Partial monosomy and partial trisomy 18 in two offspring of carrier of pericentric inversion of chromosome 18. (1/1042)

A pericentric inversion of chromosome 18 is described in the mother of a patient with clinical diagnosis of 18q--syndrome. The propositus' chromosome complement includes the recombinant 18 with deficiency of the distal one-third of the long arm and duplication of the terminal segment of the short arm. The propositus' sister carrier the recombinant 18 with a duplication of the distal one-third of the long arm and a deficiency of the terminal segment of the short arm. The relative length of the inverted segment represents about 60% of the total chromosome 18 length. The probability of recombinant formation following the occurrence of a chiasma within the inverted segment is predicted to be high.  (+info)

Modification of non-conservative double-strand break (DSB) rejoining activity after the induction of cisplatin resistance in human tumour cells. (2/1042)

The induction of collateral radioresistance after the development of cisplatin resistance is a well-documented phenomenon; however, the exact processes that are responsible for the cisplatin-induced radioresistance remain to be elucidated. There was no obvious difference in the level of radiation-induced DNA double strand breaks (DSBs), in DSB rejoining rates, or the level of the catalytic subunit of the DNA-dependent protein kinase (DNA-PKcs) in the cisplatin- and radiation-sensitive 2780/WT and cisplatin-resistant 2780/CP cell lines. However, there was a significantly (P < 0.01) lower level of DSB misrejoining activity within nuclear protein extracts derived from the cisplatin- and radiation-sensitive 2780/WT and OAW42/WT tumour cell lines than in similar extracts from their cisplatin- (and radiation-) resistant 2780/CP and OAW42/CP counterparts. All of the DSB misrejoining events involved deletions of between 134 and 444 bp that arose through illegitimate recombination at short repetitive sequences, such as those that arise through non-homologous repair (NHR). These data further support the notion that the radiosensitivity of DSB repair proficient human tumour cell lines may be partly determined by the predisposition of these cell lines to activate non-conservative DSB rejoining pathways. Furthermore, our data suggest that the induction of acquired cisplatin resistance is associated with a two- to threefold decrease in the activity of a non-conservative DSB rejoining mechanism that appears to be a manifestation of NHR.  (+info)

Abnormalities at 14q32.1 in T cell malignancies involve two oncogenes. (3/1042)

The TCL1 oncogene on human chromosome 14q32.1 is involved in the development of T cell leukemia in humans. Its expression in these leukemias is activated by chromosomal translocations and inversions at 14q32.1. Here we report the isolation and characterization of a new member of the TCL1 gene family, TCL1b, located approximately 16 kb centromeric of TCL1. The 1.2-kb TCL1b cDNA encodes a 14-kDa protein of 128 aa and shows 60% similarity to Tcl1. Expression profiles of TCL1 and TCL1b genes are very similar: both genes are expressed at very low levels in normal bone marrow and peripheral lymphocytes but are activated in T cell leukemia by rearrangements of the 14q32.1 region. Thus, translocations and inversions at 14q32. 1 in T cell malignancies involve two oncogenes.  (+info)

Multiple DNA binding activities of the novel site-specific recombinase, Piv, from Moraxella lacunata. (4/1042)

The recombinase, Piv, is essential for site-specific DNA inversion of the type IV pilin DNA segment in Moraxella lacunata and Moraxella bovis. Piv shows significant homology with the transposases of the IS110/IS492 family of insertion elements, but, surprisingly, Piv contains none of the conserved amino acid motifs of the lambda Int or Hin/Res families of site-specific recombinases. Therefore, Piv may mediate site-specific recombination by a novel mechanism. To begin to determine how Piv may assemble a synaptic nucleoprotein structure for DNA cleavage and strand exchange, we have characterized the interaction of Piv with the DNA inversion region of M. lacunata. Gel shift and nuclease/chemical protection assays, competition and dissociation rate analyses, and cooperativity studies indicate that Piv binds two distinct recognition sequences. One recognition sequence, found at multiple sites within and outside of the invertible segment, is bound by Piv protomers with high affinity. The second recognition sequence is located at the recombination cross-over sites at the ends of the invertible element; Piv interacts with this sequence as an oligomer with apparent low affinity. A model is proposed for the role of the different Piv binding sites of the M. lacunata inversion region in the formation of an active synaptosome.  (+info)

The frequency and allelism of lethal chromosomes in isolated desert populations of Drosophila pseudoobscura. (5/1042)

Second-chromosome lethals were extracted from four populations of Drosophila pseudoobscura in Southern California. Two of the populations were from desert oases and two from the classic habitat on Mt. San Jacinto, previously studied by Dobzhansky. Allelism tests were made on the lethals within and between all locations. The frequency of lethal second-chromosomes in each location was 0.18, and this was not different from the results of other workers for samples throughout the species range. Interpopulational allelism rates were about 0.005, and not different from earlier results of Dobzhansky. Intrapopulational rates in this study were, with one exception, the same as the interpopulational rates, and significantly lower than Dobzhansky found using the third chromosome. This may be due to lethals being linked with heterotic third-chromosome inversions. The allelism rate of the exceptional population (about 0.03 and equal to Dobzhansky's intrapopulational results) may be due to heterotic lethals, or a founder effect. Two lethals were found in three populations each, possibly due to migration among these populations, which are up to 334 km apart.  (+info)

Gene differences between third-chromosome inversions of Drosophila pseudobscura. (6/1042)

Associations of alleles of the acid phosphatase-3 locus with the different third-chromosome inversions from different populations of D. pseudoobscura are described.

The Chiricahua gene arrangement is polymorphic.  (+info)

A 189-bp repeat region within the human cytomegalovirus replication origin contains a sequence dispensable but irreplaceable with other sequences. (7/1042)

The human cytomegalovirus (HCMV) replication origin exhibits a strain-dependent difference in the number of copies of a 189-bp region: the AD169 and Towne strains contain one and three copies of the region, respectively. A nearly complete deletion of the 189-bp repeat region of the Towne strain does not eliminate the origin's ability to initiate DNA synthesis. Here we report that the replication ability of the HCMV replication origin in infected cells disappeared after replacements of an internal sequence (152 bp) of the 189-bp repeat region with lambda DNA of identical and different lengths as well as after introduction of multiple nucleotide substitutions within the 152-bp internal sequence of the 189-bp repeat. In contrast, a variation in the copy number of 189-bp region (either one or two copies) or an inversion of the 152-bp internal sequence of the 189-bp repeat maintained replication abilities similar to those of the wild-type origin of the Towne strain. These results indicate that the 189-bp repeat region within the HCMV replication origin is not just a dispensable spacer sequence but instead contains an irreplaceable sequence that may play a supporting role in HCMV DNA replication.  (+info)

Selective sweep at the Drosophila melanogaster Suppressor of Hairless locus and its association with the In(2L)t inversion polymorphism. (8/1042)

The hitchhiking model of population genetics predicts that an allele favored by Darwinian selection can replace haplotypes from the same locus previously established at a neutral mutation-drift equilibrium. This process, known as "selective sweep," was studied by comparing molecular variation between the polymorphic In(2L)t inversion and the standard chromosome. Sequence variation was recorded at the Suppressor of Hairless (Su[H]) gene in an African population of Drosophila melanogaster. We found 47 nucleotide polymorphisms among 20 sequences of 1.2 kb. Neutrality tests were nonsignificant at the nucleotide level. However, these sites were strongly associated, because 290 out of 741 observed pairwise combinations between them were in significant linkage disequilibrium. We found only seven haplotypes, two occurring in the 9 In(2L)t chromosomes, and five in the 11 standard chromosomes, with no shared haplotype. Two haplotypes, one in each chromosome arrangement, made up two-thirds of the sample. This low haplotype diversity departed from neutrality in a haplotype test. This pattern supports a selective sweep hypothesis for the Su(H) chromosome region.  (+info)

When the homologous chromosomes pair in prophase I of meiosis, the genes on the chromosomes pair up. The only way this can happen after an inversion is if the homologous pairs form a loop. If a cross-over occurs within this inversion loop, it can lead to loss or gain of DNA. For this reason, people with inversions in their germ cells often have lower fertility. This is because the gametes are damaged. Families that are carriers of inversions may be offered genetic counselling and testing.[1]. ...

In summary, we propose that the relatively frequent occurrence and accumulation of inversions in genomes may be a major contributor to the phenomenon of intra-strand parity. Whereas single base substitutions might explain Chargaffs second parity rule at the level of mononucleotides, they can explain neither the high-order intra-strand parity nor the exceptional deviation of mammalian mtDNAs. In contrast, inversion events are not limited by size and can involve millions of bases of sequence. Other mechanisms may have contributed to some extent; nevertheless, they are not necessary to account for intra-strand parity if inversions are considered.. Inversions are one process contributing to genome evolution that allow for rearrangement toward optimal position, order, and orientation of genes and regulatory elements, and for escape from deleterious effects caused, for example, by some duplications. Although we acknowledge the possibility of preferential sites, inversions occur randomly as shown in ...
The human and chimpanzee genomes are distinguishable in terms of ten gross karyotypic differences including nine pericentric inversions and a chromosomal fusion. Seven of these large pericentric inversions are chimpanzee-specific whereas two of them, involving human chromosomes 1 and 18, were fixed in the human lineage after the divergence of humans and chimpanzees. We have performed detailed molecular and computational characterization of the breakpoint regions of the human-specific inversion of chromosome 1. FISH analysis and sequence comparisons together revealed that the pericentromeric region of HSA 1 contains numerous segmental duplications that display a high degree of sequence similarity between both chromosomal arms. Detailed analysis of these regions has allowed us to refine the p-arm breakpoint region to a 154.2 kb interval at 1p11.2 and the q-arm breakpoint region to a 562.6 kb interval at 1q21.1. Both breakpoint regions contain human-specific segmental duplications arranged in ...
Structural Changes in the Chromosomes Some times the material in an individual chromosome is disrupted or rearranged. This may involve the addition or loss of chromosome material like chromosome deletions, chromosome duplications, chromosome insertions, chromosome inversions or chromosome translocations. Any change in the number, size or structure of our chromosomes may cause a change in the amount or arrangement of genetic information, and further may lead to a cancer development. To find out which chromosome aberrations characterized which tumor types therefore emerged as a very fruitful field of research. In principle, three types of aberrations were found: those involving balanced interchanges of chromosomal material (translocations, insertions, inversions), those leading to loss of genomic material (deletions, unbalanced translocations, losses of whole chromosome copies), and those leading to gain of genomic material (duplications, unbalanced translocations, gains of whole chromosome ...
A site-specific inversion event is responsible for phase transition in Salmonella, as indicated by heteroduplex analysis of recombinant molecules carrying the gene coding for H2 flagellin in Salmonella. The inversion region corresponds to approximately 800 base pairs in length, and the inversion process does not appear to be dependent upon the E. coli RecA recombination pathway. Specific deletion derivatives of the cloned fragments no longer produce H2-specific flagella, effectively mapping the H2 gene within about 300 bp of the inversion region. Recombinant products of the hybrid molecules arose spontaneously, and they were used in the mapping of restriction sites within the inversion region. The restriction maps further demonstrate the extent and nature of the inversion.
A theoretical analysis of the effects of inversions on recombination and gene flux between arrangements caused by gene conversion and crossing over was carried out. Two different mathematical models of recombination were used: the Poisson model (without interference) and the Counting model (with interference). The main results are as follows. (1) Recombination and gene flux are highly site-dependent both inside and outside the inverted regions. (2) Crossing over overwhelms gene conversion as a cause of gene flux in large inversions, while conversion becomes relatively significant in short inversions and in regions around the breakpoints. (3) Under the Counting model the recombination rate between two markers depends strongly on the position of the markers along the inverted segment. Two equally spaced markers in the central part of the inverted segment have less recombination than if they are in a more extreme position. (4) Inversions affect recombination rates in the uninverted regions of the ...
This study shows that association mapping can be used to map regions within inversions controlling variation in quantitative traits. In the parental generation, we found three alleles from two separate regions within In(3R)Payne with a significant additive effect on wing size after the background effect of the inversion was taken into account. Further, we were able to show that two of the significantly associated alleles, one from each of the two regions, had effects on size that were independent of the other. None of the alleles located outside In(3R)Payne were significantly associated with wing size. The two associated genomic regions were located near the proximal breakpoint at 89E and toward the distal side of the inversion at 95C. The distances between the nearest nonassociated markers either side of the two regions were 883 and 1029 kb, respectively. These distances represent ∼0.49 and 0.57% of the total genome and each contain between 181 and 219 genes according to FlyBase (Grumbling et ...

The polymorphic inversion on 17q21, sometimes called the microtubular associated protein tau (MAPT) inversion, is an ∼900 kb inversion found primarily in Europeans and Southwest Asians. We have identified 21 SNPs that act as markers of the inverted, i.e., H2, haplotype. The inversion is found at the highest frequencies in Southwest Asia and Southern Europe (frequencies of ∼30%); elsewhere in Europe, frequencies vary from less than 5%, in Finns, to 28%, in Orcadians. The H2 inversion haplotype also occurs at low frequencies in Africa, Central Asia, East Asia, and the Americas, though the East Asian and Amerindian alleles may be due to recent gene flow from Europe. Molecular evolution analyses indicate that the H2 haplotype originally arose in Africa or Southwest Asia. Though the H2 inversion has many fixed differences across the ∼900 kb, short tandem repeat polymorphism data indicate a very recent date for the most recent common ancestor, with dates ranging from 13,600 to 108,400 years, ...

Drosophila paulistorum populations colonizing the urban area of Porto Alegre, southern Brazil, were studied with the objective of characterizing their chromosomal polymorphism in this new environment. Despite being geographically and ecologically marginal and the fact that the colonization of the urban area seems to be a recent event, the populations showed a large number of inversions on all chromosome arms. Differences regarding inversion frequencies and percentage of heterozygosis were found when we compared the samples with respect to geographical, microenvironmental and temporal aspects. Such differences, however, could be attributed to both selective and stochastic factors. ...

Chromosome 9 inversion is when there are two breaks on chromosome 9. The segment between the breakpoints flips around and reinserts back into the same place on chromosome 9. If both breaks occur in the same arm of the chromosome, this is called a paracentric inversion. If one break occurs in the short arm and the other in the long arm of the chromosome, then this is called a pericentric inversion. Chromosome 9 inversions commonly occur as a pericentric inversion ...

Significant advances have been made over the past 5 years in mapping and characterizing structural variation in the human genome. Despite this progress, our understanding of inversion variants is still very restricted. While unbalanced variants such as copy number variations can be mapped using array-based approaches, strategies for characterization of inversion variants have been limited and underdeveloped. Traditional cytogenetic approaches have long been able to identify microscopic inversion events, but discovery of submicroscopic events has remained elusive and largely ignored. With the advent of paired-end sequencing approaches, it is now possible to map inversions across the human genome. Based on the paired-end sequencing studies published to date, it is now feasible to make a first map of inversions across the human genome and to use this map to explore the characteristics and distribution of this form of variation. The current map of inversions indicates that many remain to be identified,
Background: the human chromosome 8p23.1 region contains a 3.8-4.5 Mb segment which can be found in different orientations (defined as genomic inversion) among individuals. The identification of single nucleotide polymorphisms (SNPs) tightly linked to the genomic orientation of a given region should be useful to indirectly evaluate the genotypes of large genomic orientations in the individuals. Results: we have identified 16 SNPs, which are in linkage disequilibrium (LD) with the 8p23.1 inversion as detected by fluorescent in situ hybridization (FISH). The variability of the 8p23.1 orientation in 150 HapMap samples was predicted using this set of SNPs and was verified by FISH in a subset of samples. Four genes (NEIL2, MSRA, CTSB and BLK) were found differentially expressed (p|0.0005) according to the orientation of the 8p23.1 region. Finally, we have found variable levels of mosaicism for the orientation of the 8p23.1 as determined by FISH. Conclusion: by means of dense SNP genotyping of the region,

A variety of evidence has suggested that the enigmatic Australian-Antarctic Discordance is caused by a cold zone beneath the present-day South East Indian Ridge south of Australia. We show that the present position of the subduction zone which surrounded Gondwanaland until the Mesozoic is within a few hundred kilometres of the Australian-Antarctic Discordance. Beneath the Australian-Antarctic Discordance, tomographic inversions show a north-south-trending seismic anomaly with a higher than average shear velocity in the lower mantle and a prominent, nearly circular, high-velocity anomaly within the transition zone. These seismic inversions are consistent with the predictions of three-dimensional models of mantle convection with imposed plate tectonics. However, these earlier models, incorporating only a thermal slab, resulted in a circular topographic depression on the present South East Indian Ridge and are inconsistent with the observed residual depth anomaly which is continuous from the South ...

The normal, pyramidal morphology of some of the neurons incdk5 −/− deserves further comment. Analysis of the reeler mutation raised the possibility that disruption of pyramidal morphology and cortical inversion are directly linked. In the cdk5 −/− cerebral cortex, however, the earliest cortical plate neurons are superficial to all later born cells yet still have a pyramidal morphology. One important difference between early cortical plate neurons in reelerand cdk5 −/− mice that may explain this disparity is the normal location of some layer VI cells between the subplate and marginal zone in cdk5 −/−mice. Perhaps only within the environment between subplate and marginal zone can cortical neurons achieve a normal pyramidal morphology. In this position, young neurons would be able to interact with Cajal-Retzius cells of the marginal zone and their secreted factor, reelin. This interaction might then serve as a mechanism to confer a pyramidal morphology.. A persistent question raised ...
Some inversions are hot. Others? Well, shoulderstand remains understated for a reason, but here are seven reasons youre about to introduce a lot more of it to your practice.
The effect of face inversion has been heavily studied, whereas fewer studies have investigated inversion in scenes. We investigated the influence of scene inversion on decisions and contextual guidance of eye movements during visual search. A saccade contingent display termination paradigm was used to assess the temporal dynamics of the effect. Observers searched for a computer mouse in office scenes and performed a yes/no detection task. Observers sensitivity (d) was lower for inverted images relative to upright. Observers false positive rate decreased with additional eye movements when they viewed upright images, but remained constant during the first three eye movements when viewing inverted images. The average distance of observers eye movements to the target location was greater for inverted than upright scenes. We interpret that inverting an image disrupts the rapid extraction of scene gist, subsequently disrupting guidance in eye movement behavior and slowing the process of rejecting ...

A new solution to the inversion of Fraunhofer diffraction for particle sizing was introduced. Com pared with the well-known Chin-Shifrin inversion, it is an inversion of the form of integral transform and less sensitive to noise. Simulation results with noise-contaminated data were obtained and showed that the new inversion is better than the Chin-Shifrin inversion. Especially when the particle diameter was small, the new inversion still performed well, whereas the Chin-Shifrin inversion did not converge.. © 2009 Optical Society of America.

by Wes Ishmael for Angus Productions Inc.. Trichomoniasis can be economically devastating enough that some producers who have gone through it are no longer producers, said Craig Payne, DVM, director of medical extension and continuing education at the University of Missouri (MU). Thats because of the open cows and the extended calving seasons resulting from trichomoniasis (trich) infection. Speaking at the Applied Reproductive Strategies in Beef Cattle (ARSBC) symposium in Joplin, Mo., Payne explained that the average number of open cows runs an average of 40%-50% in naïve herds exposed to trichomoniasis.. Incidentally, he explained, subsequent infections in a herd affect fewer cows because some will build immunity to the disease that can last up to 15 months.. Theres nothing new about trich, but it continues to grow beyond the western boundaries typically associated with it. For instance, Payne said, Up until the last few years, the disease was almost non-existent in Missouri, but now ...
Max Payne 2 is a classic case of horses for courses. Some of you like the film noir love story, the comic book styling, the over the top Voiceover Man narrative, and the self-referential humour in Dick Justice, Captain Baseball man and Lords And Ladies. Some of you, however, simply despise it. Opinions are like arseholes - weve all got them, its just that some of you get haemorrhoids from straining the point a little too hard. Just relax, enjoy yourself. You might have fun.. Rather than take six or seven years reinventing the wheel, Remedy has thrown in a refined bullet time system, vastly improved enemy behaviour, buddy AI, relentlessly enjoyable splendidly implemented Havok 2 physics and some of the most intricately illustrated gaming environments ever. Honestly, its hard to see whats not to like about it (although were priming the comment thread in expectation that some of you will delight in doing just that). Its the sequel to Max Payne; of course its going to be broadly similar to ...

Although inversion therapy is a time-tested method for the treatment of back pain and promotion of general health, affordable inversion tables are now bringing this proven approach into the mainstream.. Inversion therapy addresses back pain associated with spinal compression and has become a viable alternative to anti-inflammatory medications, cortisone injections and electrical stimulation.. The Paradigm 500 Inversion Table is very similar to the Ironman Gravity series. The system features comfortable foot straps and uses a patented ratchet ankle mechanism that lets you adjust the tightness of the cushions with the touch of a button. Inversion can put stress on the feet and ankles so this extra feature is essential in our opinion.. ...
The Y-STR DYS19 is firmly established in the repertoire of Y-chromosomal markers used in forensic analysis yet is poorly understood at the molecular level, lying in a complex genomic environment and exhibiting null alleles, as well as duplications and occasional triplications in population samples. Here, we analyse three null alleles and 51 duplications and show that DYS19 can also be involved in inversion events, so that even its location within the short arm of the Y chromosome is uncertain. Deletion mapping in the three chromosomes carrying null alleles shows that their deletions are less than ∼300 kb in size. Haplotypic analysis with binary markers shows that they belong to three different haplogroups and so represent independent events. In contrast, a collection of 51 DYS19 duplication chromosomes belong to only four haplogroups: two are singletons and may represent somatic mutation in lymphoblastoid cell lines, but two, in haplogroups G and C3c, represent founder lineages that have ...
Although the initial studies had suggested a shared duplication topography among the three brothers, fine mapping revealed additional chromosomal rearrangements specific for each of the three individuals. Cohybridization of YAC800A7 (green) and YAC799D2 (red; D9S1852, D9S281, and D9S1849) from the duplicated region displayed the same signal pattern for 3.3 and 3.5, but the difference detected a large inversion in 3.4 (Fig. 1C) ⇓ with the green signal flanked by two red signals to produce a red/green/red pattern. The inverted region appears to span ,12 cM. Furthermore, in 3.3 PACs, RPCI225N21 (green, D9S256) and RPCI168I6 (red, proximal to D9S269) from the proximal border of the duplicated region produced a normal signal but revealed in both 3.4 and 3.5 an inversion (Fig. 1D) ⇓ that changed the normal distal-green/proximal-red into a proximal-green/distal-red pattern. These PACs are located within a 2-cM interval inside of the inverted region in 3.4 and displayed the expected inverted ...
The Walden Inversion is the only phenomenon connected with optically active compounds for which a possible explanation is not forthcoming on the theories of Pasteur, vant Hoff and Le Bel. Since sign of rotatory power and configuration do not go hand in hand, there are two aspects of this problem Before it is known whether a Walden inversion has occurred it is necessary to decide whether the product and the parent compound have the opposite configuration, and there is also the detection of the causes which bring about the inversion. From a consideration of the reactions of the p-toluene-sulphinic and p-toluenesulphonic esters of 1(-)-beta-octanol and 1(-)-phenylmethylcarbinol, it is shown in the present work that each of these laevorotatory alcohols has the same configuration as its laevorotatory halide. Further, these esters are shown to undergo definite inversion reactions which probably have a relatively simple mechanism. A study of the decomposition of the chloro-formates of these two ...
scoreInvHap can get the samples inversion status of known inversions. scoreInvHap uses SNP data as input and requires the following information about the inversion: genotype frequencies in the different haplotypes, R2 between the region SNPs and inversion status and heterozygote genotypes in the reference. The package include this data for two well known inversions (8p23 and 17q21.31) and for two additional regions.
Just a note: If you suffer from high blood pressure, eye diseases (such as glaucoma) have heart disease or are pregnant you need to check with your doctor before you start an Inversion program. The first time anyone uses this type of therapy, you should have someone standing by just in case of any issues and to help you step out of the flatbed part.. With all the benefits of Inversion Tables you can see how this might be the right option for you. Imagine alleviating the pressure on your nerve roots and spinal cord ligaments, getting help with your posture, stimulating circulation, reducing muscle aches and stress. Using one of these devices can allow your discs to recover lost moisture due to injury and allows your discs to return to their original form. Dont forget that some of them are great for exercising your back muscles as well as your core or abdominal muscles. It is just a matter of choosing the best Inversion Therapy table for you.. Here is how the inversion table works:. You climb on ...
Possibly, you have heard about inversion tables and just how beneficial they could be in your exercise routine. Okay, here are just a little information and facts that may help you learn what they do, the theories of them and also exactly what to consider when buying one.. Inversion therapy: a quick intro. What is inversion therapy? It is the actual practice of inverting ones body (in other words, other words hanging upside down, commonly on an inversion table) so that you can lengthen and also straighten your spine. The particular concept goes that as gravity pulls down on the ones head, shoulders and also back, it can help reverse the compression which gravity causes when you are proper side up every other moment of the day.. You know why you may need inversion therapy to reverse that pressure? All the nerves within your body ultimately make their way back towards the spinal cord, which usually will go to your brain. If any of those nerves usually is kinked or pinched since the spine is ...

For this reason deinvert has a quality setting (0 to 3) for controlling the number of samples in the convolution kernels. A filter with a shorter kernel is linearly faster to compute, but has a low roll-off and will leave more unwanted harmonics.. A quality setting of 0 turns filtering off completely, and is very fast. For simple inversion this should be fine, as long as the original doesnt contain much power above the inversion carrier. Its easy to ignore the upper sideband because of its high frequency. In split-band descrambling this leaves some nasty folded harmonics in the speech band though.. Heres a descramble of the above CMX264 split-band audio using all the different quality settings in deinvert. You will first hear it scrambled, and then descrambled with increasing quality setting.. ...

Anopheles gambiae sensu stricto, one of the principal vectors of malaria, has been divided into two subspecific groups, known as the M and S molecular forms. Recent studies suggest that the M form found in Cameroon is genetically distinct from the M form found in Mali and elsewhere in West Africa, suggesting further subdivision within that form. Chromosomal, microsatellite and geographic/ecological evidence are synthesized to identify sources of genetic polymorphism among chromosomal and molecular forms of the malaria vector Anopheles gambiae s.s. Cytogenetically the Forest M form is characterized as carrying the standard chromosome arrangement for six major chromosomal inversions, namely 2La, 2Rj, 2Rb, 2Rc, 2Rd, and 2Ru. Bayesian clustering analysis based on molecular form and chromosome inversion polymorphisms as well as microsatellites describe the Forest M form as a distinct population relative to the West African M form (Mopti-M form) and the S form. The Forest-M form was the most highly diverged
An isolate originally labeled Bacillus megaterium CDC 684 was found to contain both pXO1 and pXO2, was non-hemolytic, sensitive to gamma-phage, and produced both the protective antigen and the poly-D-glutamic acid capsule. These phenotypes prompted Ezzell et al., (J. Clin. Microbiol. 28:223) to reclassify this isolate to Bacillus anthracis in 1990. We demonstrate that despite these B. anthracis features, the isolate is severely attenuated in a guinea pig model. This prompted whole genome sequencing and closure. The comparative analysis of CDC 684 to other sequenced B. anthracis isolates and further analysis reveals: a) CDC 684 is a close relative of a virulent strain, Vollum A0488; b) CDC 684 defines a new B. anthracis lineage (at least 51 SNPs) that includes 15 other isolates; c) the genome of CDC 684 contains a large chromosomal inversion that spans 3.3 Mbp; d) this inversion has caused a displacement of the usual spatial orientation of the origin of replication (ori) to the termination of replication
The human sex chromosomes have stopped recombining gradually, which has left five evolutionary strata on the X chromosome. Y inversions are thought to have suppressed X-Y recombination but clear evidence is missing. Here, we looked for such evidence by focusing on a region-the X-added region (XAR)-that includes the pseudoautosomal region and the most recent strata 3 to 5. We estimated and analyzed the whole set of parsimonious scenarios of Y inversions given the gene order in XAR and its Y homolog. Comparing these to scenarios for simulated sequences suggests that the strata 4 and 5 were formed by Y inversions. By comparing the X and Y DNA sequences, we found clear evidence of two Y inversions associated with duplications that coincide with the boundaries of strata 4 and 5. Divergence between duplicates is in agreement with the timing of strata 4 and 5 formation. These duplicates show a complex pattern of gene conversion that resembles the pattern previously found for AMELXY, a stratum 3 locus. ...
This ECG was obtained from a man in his 70s. We have no other clinical information. It is interesting for several reasons. Giant T wave inversions The most obvious abnormalities we see on first inspection are the deeply inverted T waves in Leads V3 through V6. The T wave in V3 is biphasic. There are also T wave inversions in all of the limb leads except aVR. The precordial T wave inversions are called giant T wave inversions because they are 10 mm or more in depth. There are many causes of giant T wave inversions, including, but not limited to: myocardial ischemia, coronary artery disease and reperfusion, pulmonary edema, massive pulmonary embolism, subarachnoid hemorrhage, apical hypertrophy, post-tachycardia syndrome, and post-pacing syndrome. What else? There are no Q waves or ST elevations. The ST segments are not entirely normal in shape, being flattened in most lead. The frontal plane axis is left. Even though the ECG almost meets criteria for left ventricular hypertrophy, by exclusion ...
This work focuses on the study and evaluation of the retrievals of aerosol complex refractive index (m = mr + imi) and single scattering albedo (SSA) from the inversion of multi-wavelength lidar measurements, particularly of three backscattering coefficients (β) at 355, 532 and 1064 nm and two extinction coefficients (α) at 355 and 532 nm, typically known as the stand-alone 3β + 2α lidar inversion. The focus is on the well-known regularization technique for spherical particles. It is well known that constraints in the range of refractive indices allowed in the inversion are essential, both for the real (mr) and imaginary (mi) parts, due to the under-determined nature of the problem. Usually these constraints are fixed for a given set of inversions. Using a large database of AERONET retrievals, correlations between retrieved mr and mi are observed and those correlations together with results from the GOCART model are used to define optimized, case-dependent, constraints in the stand-alone 3β ...

A DNA fragment of approximately 900 base pairs, adjacent to the fljB (H2) gene, which specifies the synthesis of phase-2 flagellin, can exist in either orientation with respect to fljB. The orientation of the inversion region controls expression of fljB. The hin gene occupies about two-thirds of the inversion region; it is required for the inversion of the fljB controlling region.

A study was made of the diurnal and seasonal variations of the vertical dewpoint gradient based on measurements taken at 1.2, 9.4 and 131 ft above ground at the Argonne National Laboratory during the period 1 December 1960 through 30 November 1965. The results of this study are used to assess the effects of the dewpoint temperature inversion on vegetative growth, dew formation and corrosion.. Case studies employing time series presentations are used to relate the magnitude and direction of the dewpoint gradient with other meteorological variables such as air and soil temperature, pressure, solar radiation, net radiation flux, wind speed and direction, relative humidity and stability. These analyses illustrate the processes operating to influence the magnitude and direction of moisture flux in the lower atmospheric layers.. Joint frequency distributions are presented relating the vertical dewpoint temperature gradient with each of the variables-air temperature between 144 and 5.5 feet, relative ...

The relationship between hyperactive ALK and Non-Small Cell Lung Cancer (NSCLC) is a relatively new discovery reported in 2007 in the journal Nature by Soda and colleagues in 5/75 patients (https://www.ncbi.nlm.nih.gov/pubmed/17625570) and also by Rikova et al., in the journal Cell in the same year (http://www.ncbi.nlm.nih.gov/pubmed/18083107?dopt=Abstract&holding=npg0. In these cases, ALK is activated as the consequence of a chromosomal inversion event whereby the Echinoderm microtubule-associated protein-like 4 (EML4) is juxtaposed to ALK creating a hyperactive fusion protein. Other, much rarer fusion partners for ALK have also been reported including TFG and KIF5B.. Interestingly, this fusion event is more common in patients that have never smoked and is normally mutually exclusive of mutations in the EGFR or KRAS. Patients also tend to be younger in age and present with a form of NSCLC called an adenocarcinoma.. ...
Major Payne likes to think of himself as a killing machine. Thats why hes devastated to be passed over for promotion and mustered out of the service. Surely, he begs his commanding officer, there must be another war to fight? Somebody else to kill? Sorry, Payne, hes told. Theres nobody else to kill. Youve killed them all. Back in civilian life and unemployed, he tries out for the police force, but gets carried away during a real life simulation and hammers an actor who is portraying a perpetrator. Then an old friend finds him a job, as the officer in charge of the junior ROTC cadet training corps at a private school in Virginia. This is not the job he was born to fill.
In a population-based prospective study of more than 5000 men and women aged 65 years or older, the Cardiovascular Health Study1 found a strong relation between three different measures of carotid atherosclerosis and the presence of any major abnormality, including T-wave inversions, on the resting ECG. Unfortunately, this study did not examine the prevalence of isolated T-wave abnormalities in relation to carotid disease separately from other major ECG abnormalities and included subjects with angina, myocardial infarction, and coronary revascularization.1 The strong association between nonspecific repolarization abnormalities, which included localized T-wave inversions, and subsequent coronary morbidity and mortality found in large population studies8 9 10 11 12 13 14 and the increased mortality in asymptomatic patients with carotid disease and similar nonspecific ECG abnormalities27 suggest that asymptomatic individuals with carotid hypertrophy and localized T-wave inversions on the resting ...

During inversion of a Volvox embryo, a series of cell shape changes causes the multicellular sheet to bend outward, and propagation of the bend from the anterior to the posterior pole eventually results in an inside-out spherical sheet of cells. We use fluorescent and electron microscopy to study the behavior of the cytoskeleton in cells undergoing shape changes. Microtubules are aligned parallel to the cells long axis and become elongated in the bend. Myosin and actin filaments are arrayed perinuclearly before inversion. In inversion, actin and myosin are located in a subnuclear position throughout the uninverted region but this localization is gradually lost towards the bend. Actomyosin inhibitors cause enlargement of the embryo. The bend propagation is inhibited halfway and, as a consequence, the posterior hemisphere remains uninverted. The arrested posterior hemisphere will resume and complete inversion even in the presence of an actomyosin inhibitor if the anterior hemisphere is removed ...
The nonprofit organization that Payne works for - Friends of Casco Bay - is on the campus of Southern Maine Community College in South Portland.. In his announcement, the 67-year-old Payne said he is leaving the position to spend more time with the Keeper of the Keeper, his wife, Kim. The couple live in Westbrook.. Protecting the bay has been about the work, but more than that its been about the people I have met along the way, Payne said. Twenty four years ago, I wasnt exactly sure what I was getting into. What I found out was that there were plenty of us who care about this community and want to do our part to ensure that the Bay is passed on to the next generation better than we found it..

There are currently 240 baykeepers - also known as waterkeepers - worldwide.. Payne described Casco Bay as the coastline, islands and ocean between Cape ...
To convert light into an electrical signal, vertebrate photoreceptors use an enzymatic transduction cascade to control the circulating current that flows into the cell through cGMP‐gated channels. The intracellular level of cGMP depends on the relative activities of light‐stimulated PDE and Ca2+‐dependent GC. The present study investigates the molecular mechanisms responsible for the Ca2+ regulation of cGMP synthesis. This issue has not been resolved and is complicated by the fact that rods contain two distinct particulate guanylate cyclases (GC1 and GC2) and two different Ca2+‐sensitive activators (GCAP1 and GCAP2).. The GCAPs are among the best characterized Ca2+ binding proteins of the calmodulin superfamily, many of which are specifically expressed in neurons. The genes encoding GCAP1 and GCAP2 are related evolutionarily. They were generated by ancient gene duplication/inversion events and share an identical gene structure. On the protein level, however, the two GCAPs share only ...
We performed Full waveform inversion on two-ship, wide-aperture multi-channel seismic reflection data collected along the southern East Pacific Rise. The analysis revealed and exploited converted shear waves not previously seen in the data. From the P- and S-wave velocity structure obtained we were able to compute Poissons Ratio, an elastic parameter: the ratio of transverse contractional strain to longitudinal extensional strain (or in other words, a measure of the degree to which a material expands outwards when squeezed). In a mid-ocean ridge setting the Poisson Ratio structure gives insight into the porosity and crack distribution of the young oceanic crust. We found that the porosity is in excess of 30% in the uppermost layer (2A, the extruded pillow lavas) but reduces to 6-7% across the 2A/2B transition where the extruded pillow basalts are replayed by induced dykes (Fig.1). These results have important implications for the lithostratigraphy of young oceanic crust and hydrothermal ...

A new paper, just out in Nature Genetics, by Zody and Jiang et al. looks at the evolutionary history of the ~1Mb 17q inversion. This inversion was first described by Stefansson et al.. Stefansson et al. found the normal allele H1 was present in many populations but that the inverted allele H2, seemed to have increased rapidly in frequency in Europeans, perhaps due to positive selection, in support of this they found that the inverted allele H2 was associated with a higher birth-rate in modern day individuals in Iceland. Further sequence analysis by Stefansson et al. suggested that the two alleles (H1 and H2) diverged ~2.5-3 million years ago, which is old for a human allele and surprising given the low frequency of H2 in Africa. Since then the region has been implicated in various diseases. Zody and Jiang et al. reconstruct the history of the region and surprisingly suggest that the H2 allele is actually the ancestral state, despite the fact that it is present at low frequency world-wide. They ...

Inversion domains in III-nitride semiconductors degrade the performance of devices fabricated in them. Consequently, it is imperative that we understand their electrostatic manifestation, the growth conditions under which such domains form, and an effective means of their identification. In what is nominally referred to as Ga-polarity samples, N-polarity domains have a polarization that is reversed with respect to the remainder of the surface, and therefore, have a different potential under strain. We have used surface-potential electric-force microscopy (SP-EFM) to image the electrostatic surface potential of GaN grown on sapphire, which is strained due to the thermal mismatch between the substrate and GaN. Employing a control sample with side-by-side Ga- and N-polarity regions, we have established the EFM mode necessary to identify inversion domains on GaN samples grown by molecular-beam epitaxy. This method is not sensitive to topology and has a spatial resolution of under 100 nm. The ...
Very true as well as the addition rate (how fast or slow) will influence the phase to volume ratio for catastrophic inversion to take place. Non-ionic O/W emulsifiers typically will go through phase inversion as heating occurs anyway and then settle to the most stable morphology. I think this is what people experience with their varied methods here. Lab Rat mentions heating to the same temp kills bugs but it also will allow for phase inversion to take place or not depending again on temperature, surfactants used, which phase is added first, how much and at what rate (how fast etc.) cooling temp and rate, shear etc.. However this is not to say inversion always takes place to produce a more stable emulsion. Many things can influence stability of emulsions, not just phase to volume ratios. The problem with catastrophic inversion and why I personally dont do this method more often is you really dont know the precise time of inversion nor the actual physical conditions you end up with. So I ...
Chromosomal rearrangements, including inversions and translocations, may play dual roles in speciation. First, rearrangements can (and must, in the case of most translocations) cause F1 hybrid sterility, generating costs of heterozygosity that make their spread to define species paradoxical. Second, they suppress recombination in heterozygotes, and thus contribute to the packaging of locally adapted traits and other reproductive barriers in the face of gene flow. Current projects include studies of inversion polymorphism within Mimulus guttatus (e.g. Lee, Fishman et al. 2016) and work on rearrangements and reproductive barriers in the M. cardinalis complex (e.g., Fishman et al. 2013, Stathos & Fishman 2014). ...

Usually organisms that have a higher rate of reproduction than their competitors have an evolutionary advantage. Consequently, organisms can evolve to become simpler and thus multiply faster and produce more offspring, as they require fewer resources to reproduce. A good example are parasites such as Plasmodium - the parasite responsible for malaria - and mycoplasma; these organisms often dispense with traits that are made unnecessary through parasitism on a host.[7] A lineage can also dispense with complexity when a particular complex trait merely provides no selective advantage in a particular environment. Loss of this trait need not necessarily confer a selective advantage, but may be lost due to the accumulation of mutations if its loss does not confer an immediate selective disadvantage.[8] For example, a parasitic organism may dispense with the synthetic pathway of a metabolite where it can readily scavenge that metabolite from its host. Discarding this synthesis may not necessarily allow ...

One hypothesis for the origin of multicellularity is that a group of function-specific cells aggregated into a slug-like mass called a grex, which moved as a multicellular unit. This is essentially what slime molds do. Another hypothesis is that a primitive cell underwent nucleus division, thereby becoming a coenocyte. A membrane would then form around each nucleus (and the cellular space and organelles occupied in the space), thereby resulting in a group of connected cells in one organism (this mechanism is observable in Drosophila). A third hypothesis is that as a unicellular organism divided, the daughter cells failed to separate, resulting in a conglomeration of identical cells in one organism, which could later develop specialized tissues. This is what plant and animal embryos do as well as colonial choanoflagellates.[26][27] Because the first multicellular organisms were simple, soft organisms lacking bone, shell or other hard body parts, they are not well preserved in the fossil ...

The evolution of mammals has passed through many stages since the first appearance of their synapsid ancestors in the Pennsylvanian sub-period of the late Carboniferous period. By the mid-Triassic, there were many synapsid species that looked like mammals. The lineage leading to today's mammals split up in the Jurassic; synapsids from this period include Dryolestes, more closely related to extant placentals and marsupials than to monotremes, as well as Ambondro, more closely related to monotremes.[1] Later on, the eutherian and metatherian lineages separated; the metatherians are the animals more closely related to the marsupials, while the eutherians are those more closely related to the placentals. Since Juramaia, the earliest known eutherian, lived 160 million years ago in the Jurassic, this divergence must have occurred in the same period. After the Cretaceous-Paleogene extinction event wiped out the non-avian dinosaurs (birds being the only surviving dinosaurs) and several mammalian groups, ...

The earliest evidence of behavioral modernity first appears during the Middle Paleolithic; undisputed evidence of behavioral modernity, however, only becomes common during the following Upper Paleolithic period.[1] Middle Paleolithic burials at sites such as Krapina in Croatia (dated to c. 130,000 BP) and the Qafzeh and Es Skhul caves in Israel (c. 100,000 BP) have led some anthropologists and archeologists (such as Philip Lieberman) to believe that Middle Paleolithic cultures may have possessed a developing religious ideology which included concepts such as an afterlife; other scholars suggest the bodies were buried for secular reasons.[3][4] According to recent[when?] archeological findings from Homo heidelbergensis sites in the Atapuerca Mountains, the practice of intentional burial may have begun much earlier during the late Lower Paleolithic, but this theory is widely questioned in the scientific community.

Even mammals, including humans, show the segmented bilaterian body plan at the level of the nervous system. The spinal cord contains a series of segmental ganglia, each giving rise to motor and sensory nerves that innervate a portion of the body surface and underlying musculature. On the limbs, the layout of the innervation pattern is complex, but on the trunk it gives rise to a series of narrow bands. The top three segments belong to the brain, giving rise to the forebrain, midbrain, and hindbrain.[9] Bilaterians can be divided, based on events that occur very early in embryonic development, into two groups (superphyla) called protostomes and deuterostomes.[10] Deuterostomes include vertebrates as well as echinoderms and hemichordates (mainly acorn worms). Protostomes, the more diverse group, include arthropods, molluscs, and numerous types of worms. There is a basic difference between the two groups in the placement of the nervous system within the body: protostomes possess a nerve cord on the ...

  • People usually have 23 pairs of chromosomes. (cdc.gov)
  • Typically there are 22 non-sex chromosome pairs called autosomes, and one sex chromosome pair. (chw.org)
  • Chromosome 16 spans more than 90 million DNA building blocks (base pairs) and represents almost 3 percent of the total DNA in cells. (nih.gov)
  • The following chromosomal conditions are associated with changes in the structure or number of copies of chromosome 16. (nih.gov)
  • The final pair of chromosomes, called the sex chromosomes, determine the sex of the individual. (encyclopedia.com)
  • Children randomly get one of each pair of chromosomes from their mother and one of each pair from their father. (cdc.gov)
  • The current study will focus on the third chromosome balancers TM3 , TM6 , and TM6B . (g3journal.org)
  • FISH results in lymphoblastoid cell lines suggest the presence of mosaicism regarding the 8p23.1 inversion. (elsevier.com)
  • Mosaicism is the presence of two or more chromosome patterns in the cells of a person. (chw.org)
  • Despite of its length, the inversion cannot be detected using karyotyping due to similar band patterns on the normal and inverted chromosomes, and is therefore likely to escape attention. (biomedcentral.com)
  • Students compare banding patterns on hominid (human and ape) chromosomes, and see striking evidence of their common ancestry. (indiana.edu)
  • 1. Chromosome banding patterns provide independent confirmation of relationship in hominids, in addition to anatomical, physiological, genetic, and molecular evidence. (indiana.edu)
  • 1. actively engage in the careful analysis of chromosome banding patterns. (indiana.edu)
