Cardiac and gastrointestinal malformations, a marked increase in the incidence of LEUKEMIA, and the early onset of ALZHEIMER DISEASE are also associated with this condition. Pathologic features include the development of NEUROFIBRILLARY TANGLES in neurons and the deposition of AMYLOID BETA-PROTEIN, similar to the pathology of ALZHEIMER DISEASE.

The functional hereditary units of INSECTS.
Single-stranded complementary DNA synthesized from an RNA template by the action of RNA-dependent DNA polymerase. cDNA (i.e., complementary DNA, not circular DNA, not C-DNA) is used in a variety of molecular cloning experiments as well as serving as a specific hybridization probe.
The prophase of the first division of MEIOSIS (in which homologous CHROMOSOME SEGREGATION occurs). It is divided into five stages: leptonema, zygonema, PACHYNEMA, diplonema, and diakinesis.
A characteristic showing quantitative inheritance such as SKIN PIGMENTATION in humans. (From A Dictionary of Genetics, 4th ed)
A method for ordering genetic loci along CHROMOSOMES. The method involves fusing irradiated donor cells with host cells from another species. Following cell fusion, fragments of DNA from the irradiated cells become integrated into the chromosomes of the host cells. Molecular probing of DNA obtained from the fused cells is used to determine if two or more genetic loci are located within the same fragment of donor cell DNA.
A large collection of DNA fragments cloned (CLONING, MOLECULAR) from a given organism, tissue, organ, or cell type. It may contain complete genomic sequences (GENOMIC LIBRARY) or complementary DNA sequences, the latter being formed from messenger RNA and lacking intron sequences.
The presence of apparently similar characters for which the genetic evidence indicates that different genes or different genetic mechanisms are involved in different pedigrees. In clinical settings genetic heterogeneity refers to the presence of a variety of genetic defects which cause the same disease, often due to mutations at different loci on the same gene, a finding common to many human diseases including ALZHEIMER DISEASE; CYSTIC FIBROSIS; LIPOPROTEIN LIPASE DEFICIENCY, FAMILIAL; and POLYCYSTIC KIDNEY DISEASES. (Rieger, et al., Glossary of Genetics: Classical and Molecular, 5th ed; Segen, Dictionary of Modern Medicine, 1992)
Enzymes that are part of the restriction-modification systems. They catalyze the endonucleolytic cleavage of DNA sequences which lack the species-specific methylation pattern in the host cell's DNA. Cleavage yields random or specific double-stranded fragments with terminal 5'-phosphates. The function of restriction enzymes is to destroy any foreign DNA that invades the host cell. Most have been studied in bacterial systems, but a few have been found in eukaryotic organisms. They are also used as tools for the systematic dissection and mapping of chromosomes, in the determination of base sequences of DNAs, and have made it possible to splice and recombine genes from one organism into the genome of another. EC 3.21.1.
Congenital conditions of atypical sexual development associated with abnormal sex chromosome constitutions including MONOSOMY; TRISOMY; and MOSAICISM.
Endogenous substances, usually proteins, which are effective in the initiation, stimulation, or termination of the genetic transcription process.

Partial monosomy and partial trisomy 18 in two offspring of carrier of pericentric inversion of chromosome 18. (1/140)

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)

Pseudohermaphroditism with clinical features of trisomy 19 in an infant trisomic for parts of chromosomes 16 and 18: 47,XY,der(18),t(16;18)(p12;q11)mat. (2/140)

The case is presented of an infant who was diagnosed clinically as trisomy 18 with pseudohermaphroditism. Cytogenetic studies revealed an extra chromosome which represented a translocation chromosome derived from a balanced, reciprocal translocation between chromosomes 16 and 18: [der(18),t(16;18)(p12;q11)mat]. The infant's mother and a number of her relatives were found to be translocation carriers: ]46,XX,t(16;18)(p12;q11)].  (+info)

G-banding analysis of complex aneuploidy in multiple myeloma bone marrow cells. (3/140)

Chromosome studies with the banding technique have been performed in a considerable number of cases of myeloproliferative diseases, but technical difficulties have so far prevented detailed studies of chromosomal abnormalities in multiple myeloma. The karyotypes of bone marrow cells from two patients with multiple myeloma have been analyzed by a trypsin-Giemsa banding technique. Evidence is given for clonal evolution which in one patient has probably occurred by cell fusion and subsequent chromosome loss. Eight different marker chromosomes are characterized. Nonrandom chromosomal participation in the translocations and the existence of specific vulnerable points on chromosomes 1, 3, and 16 are suggested.  (+info)

Chromosomal banding patterns in acute nonlymphocytic leukemia. (4/140)

Bone marrow chromosomes obtained from 50 of 55 consecutive adult patients with acute nonlymphocytic leukemia were analyzed with quinacrine fluorescence. Twenty-five patients showed a normal karyotype and 25 an abnormal karyotype on the initial samples available for analysis. Among the 25 patients with abnormalities, the marrow cells contained 48 chromosomes in one case, 47 in two, 46 in ten, 45 in nine, 43 in two, and 42 chromosomes in one case. Seven of the ten patients with 46 chromosomes had abnormalities, primarily balanced translocations, that were not detected with the standard Giemsa stains. The analysis of all of the data available revealed the presence of nonrandom chromosome changes such as the addition of No. 8, the loss of No. 7, and a gain or loss of one No. 21. the most frequent structural rearrangement was the translocation between the long arm of No. 8 and No. 21, which may also be associated with the loss of a sex chromosome. Chromosomal abnormalities decreased or disappeared during remission; the same abnormality recurred in relapse. Chemotherapy did not appear to produce a stable clone of aberrant cells. Evolution of the karyotype occurred in eight patients, in five of whom an additional No. 8 was observed. This pattern of chromosomal evolution in patients with acute leukemia was very similar to that observed in patients with chronic myelogenous leukemia in the blast phase.  (+info)

Trisomy 21 with 47,+18 lymphocyte cell line: double mitotic nondisjunction. (5/140)

A patient with Down's syndrome was found to have 47,XX,+18/47,XX,+21 mosaicism. Chromosome 18 trisomy was found only in 18% of lymphocytes and not in skin fibroblasts. A likely interpretation is double nondisjunction in a single lymphocyte precursor of a trisomy 21 embryo. A brief review of other cases of mitotic multiple nondisjunction and double aneuploid mosiacism is presented.  (+info)

Nature of telomere dimers and chromosome looping in human spermatozoa. (6/140)

Specific and well-organized chromosome architecture in human sperm cells is supported by the prominent interactions between centromeres and between telomeres. The telomere-telomere interactions result in telomere dimers that are positioned at the nuclear periphery. It is unknown whether composition of sperm telomere dimers is random or specific. We now report that telomere dimers result from specific interactions between the two ends of each chromosome. FISH using pairs of subtelomeric DNA probes that correspond to the small and long arms of seven human chromosomes demonstrates that subtelomeres of one chromosome are brought together. Statistical analysis confirmed that telomere associations could not result from the random proximity of DNA sequences. Therefore, chromosomes in human sperm nuclei adopt a looped conformation. This higher-order chromosome structure is most likely required for chromosome withdrawal/decondensation during the early fertilization events leading to zygote formation.  (+info)

Transformation of human cells by SV40 virus. (7/140)

Fibroblast cultures were prepared from skin biopsies from 29 patients and tested for their susceptibility to transformation by simian virus SV40. Cells with a normal chromosome complement showed a mean transformation frequency of 25/106 cells but for cells from a single patient with Fanconi's anaemia, the value was 152/106 cells. An increased susceptibility to transformation was observed for cells from 6 patients with Down's syndrome 3 patients with trisomy 18, a patient with trisomy 18 for 5% of cells and a patient with trisomy 13. No increased susceptibility to transformation was found for cells with a chromosome complement of XO, XXY, XX/XX + 8, XX + partial 15q or XX + 9p. The susceptiability to transformation was related to susceptibility to SV40 virus infection, as measured by the number of infected cells which contained SV40 virus induced T antigen. This latter test was technically easier to perform and could serve to detect persons of increased susceptiability to transformation, since this may indicate an increased risk of natural malignant disease.  (+info)

Cigarette smoking, familial hematopoietic cancer, hair dye use, and risk of t(14;18)-defined subtypes of non-Hodgkin's lymphoma. (8/140)

Some evidence suggests that smoking, a family history of hematopoietic cancer, and use of hair dyes are associated with t(14;18)-defined subsets of non-Hodgkin's lymphoma (NHL) in men. To further evaluate these associations and to expand them to women, the authors determined t(14;18)(q32;q21) status by fluorescence in situ hybridization in 172 of 175 tumor blocks from a population-based case-control study conducted in Nebraska during 1983-1986. Exposures in 65 t(14;18)-positive cases and 107 t(14;18)-negative cases were compared with those among 1,432 controls. Odds ratios and 95% confidence intervals were calculated using polytomous logistic regression. Among men, smoking was not associated with risk of t(14;18)-positive or -negative NHL. Among women who had ever smoked cigarettes, there was an association with risk of t(14;18)-negative NHL (odds ratio (OR) = 1.9, 95% confidence interval (CI): 1.1, 3.3) but not t(14;18)-positive NHL (p-difference = 0.01). The risks for t(14;18)-negative NHL among women increased with longer duration (>30 years: OR = 2.1, 95% CI: 1.1, 4.1) and early initiation (age +info)

Since paper was expensive, he used and re-used every scrap that became available. Most interestingly, however, he made his own notebooks, not only to save expense but because it allowed for flexibility of size and arrangement. Edwardss method, as was common for the time, was stab sewing, in which a needle and thread would be drawn through the assembled pages at the margin, usually in three to five holes, depending on the size of the paper, and knotted at an end hole. Sometimes, perhaps because the sheets were not bound tightly enough or the first stitching had become loose, he added a new set of stitches through different holes. He ran the thread through the holes, connecting them, so that the thread paralleled the left edge of the paper, several millimeters from that edge.[3} he also made the covers of stiffer paper, sometimes adorned with pictures and wallpaper. His notebooks usually had around 98 pages, which he covered with writing on both sides ...

A. W. F. Edwards is one of the most influential mathematical geneticists in the history of the discipline. One of the last students of R. A. Fisher, Edwards pioneered the statistical analysis of phylogeny in collaboration with L. L. Cavalli-Sforza, and helped establish Fishers concept of likelihood as a standard of statistical and scientific inference. In this book, edited by philosopher of science Rasmus Grønfeldt Winther, Edwardss key papers are assembled alongside commentaries by leading scientists, discussing Edwardss influence on their own research and on thinking in their field overall. In an extensive interview with Winther, Edwards offers his thoughts on his contributions, their legacy, and the context in which they emerged. This book is a resource both for anyone interested in the history and philosophy of genetics, statistics, and science, and for scientists seeking to develop new algorithmic and statistical methods for understanding the genetic relationships between and among ...
Although this species may have a restricted range, it is not believed to approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence ,20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (,30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (,10,000 mature individuals with a continuing decline estimated to be ,10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern ...

The mere ability to classify people into races using their genes is unremarkable. Nigerians and Swedes can be discriminated almost perfectly using skin colour, so even the handful of genes coding for skin colour must be a sufficient tell-tale. It doesnt follow that Swedes and Nigerians are necessarily distant in DNA-space, where all DNA bases are taken into account. But Lewontins 15% is an Fst statistic-(an estimate of) genetic distance between populations, averaged across all gene loci-so it doesnt privilege genes coding for visible, racially distinctive features.. Edwardss point is that 15% between-population variation, averaged across all gene loci, makes populations distant from one another (at least on average) in gene-space. Although not as comprehensive as DNA-space, gene-space is an unbiased proxy.. We can also make Lewontins 15% more tangible. Henry Harpending proves in Kinship and Population Subdivision (2002) that Fst, the measure Lewtonin refers to, is approximately equal to ...

I have not referred to my friend Albert Edwardss views for a while. Given the rather difficult juncture at which the U.S. stock market finds itself, I thought it opportune to consult with the big guy over at Société Générale in London.. In short, Albert sees that the structural bear market in equities has not yet reached bottom. We have long said that the de-bubbling process would end only when equities become very cheap and revulsion in equities as an asset class hangs in the air like a fog, commented the famed strategist.. Equity investors are in for a rude shock. The global economy is sliding back into recession and they are still not even aware that these events will trigger another leg down in valuations, the third major bear market since the equity valuation bubble burst.

In the late 1970s Moore moved to Hollywood, where he had a supporting role in the hit film Foul Play (1978) with Goldie Hawn and Chevy Chase. The following year saw his breakout role in Blake Edwardss 10, which became one of the biggest box-office hits of 1979 and gave him an unprecedented status as a romantic leading man. Moore followed up with the comedy film Wholly Moses!, which was not a major success. In 1981 Moore appeared in the title role of the comedy Arthur, an even bigger hit than 10. Co-starring Liza Minnelli and Sir John Gielgud, it was both commercially and critically successful, Moore receiving an Oscar nomination for Best Actor, whilst Gielgud won the Best Supporting Actor Oscar for his role as Arthurs stern but compassionate manservant.

Studio 13/16 by Mathieu Lehanneur at the Centre Pompidou. This area dedicated to adolescents and designed by Mathieu Lehanneur for the Centre Pompidou (Paris) opens on 11th September 2010. This initiative called Studio 13/16, inevitably risky for a museum when aimed at a volatile teenage population, finds a functional and formal solution based on the ergonomics of the desire I dreamed about a place which was conceived and built like a television, cinema or music studio. I wanted this place to offer teenagers the same potential for action and creation as the professional equivalent. A far cry from an attempt to reconstruct a hypothetical teen style, from adolescence I have only kept this desire - and at times this capacity - to contort things and places.

Breast cancer is the second most common malignant condition after cervical carcinoma in India. The first sign is usually a palpable lump in the breast, which is diagnosed further with other investigative procedures like mammography and final diagnosis is confirmed by histological techniques through biopsy of the specimen. The genetic basis of breast cancer has been studied excessively77. BRCA 1 has been excessively implicated in breast cancer. Dermatoglyphics is a scientific method of study of patterns in finger tips, palms and soles. This pattern is unique to every individual and permanently fixed, with no changes after a set formation. In various studies, the dermatoglyphic pattern variations in patients with genetic diseases like Downs syndrome, schizophrenia, and certain cancer types, like, breast cancer, ovarian cancer has been studied extensively. Therefore, this method of non- invasive technique can be used as a predictor in persons prone for certain diseases when there is significant ...
Dumb Science, Kerrys Religion We already knew Kerry had a plan for everything -- ending the war, not getting in the war in the first place, getting allies to join us in the war, saving Social Security, lowering taxes, vastly increasing spending, cutting the deficit in half. You know. Miracles. But who knew that Kerry and Edwards could cause the crippled to rise up and walk? I dont think that has ever been promised in a political campaign before. I was amused when Kerry said, during the second debate, I believe in science. That was a pretty clear contrast with George W. Bush, who believes in God. The real difference in their faiths is that George W. Bush has actually read the Bible and gone to church, so chances are he knows something about what Christians believe about God. Unfortunately, John Kerry has no idea what scientists believe about science.

From NCBI Gene:. The gene variously symbolized ALL1, HRX, or MLL located on 11q23 has been demonstrated to be fused with a number of translocation partners in cases of leukemia. t(1;11)(q21;q23) translocations that fused the MLL gene to a gene on chromosomal band 1q21 in 2 infants with acute myelomonocytic leukemia have been demonstrated. The N-terminal portion of the MLL gene is critical for leukemogenesis in translocations involving band 11q23. This gene encodes 90 amino acids. It was found to be highly expressed in the thymus but not in peripheral lymphoid tissues. In contrast to its restricted distribution in normal hematopoietic tissue, this gene was expressed in all leukemic cell lines tested. [provided by RefSeq, Jul 2008]. From UniProt: ...

Jonathan Edwards and Transatlantic Print Culture tells the story of how Edwardss works were published in the eighteenth century. Indiviidual chapters discuss the contributions of the various people who were involved on both sides of the Atlantic and their motivations. In the process of this narrative, Jonathan Edwards and Transatlantic Print Culture explains what the printing, publishing, and editing of Jonathan Edwardss publications can tell us about religious print culture in the eighteenth century. More specifically, it clarifies how the way in which his books were put together shaped the understanding of him as an author, and how such details as the formats, costs, quality of paper, length, bindings, and the number of reprints and abridgments affected the reception of his works in America and Europe. The book situates Edwards and his works in the specifics of his time and place, with extensive background on colonial commerce and the contributions of geography to printing and publishing.
