Cell Nucleus Structures
Structures that are part of or contained in the CELL NUCLEUS.
Plastic Embedding
The infiltrating of histological specimens with plastics, including acrylic resins, epoxy resins and polyethylene glycol, for support of the tissues in preparation for sectioning with a microtome.
Cell Nucleus
Within a eukaryotic cell, a membrane-limited body which contains chromosomes and one or more nucleoli (CELL NUCLEOLUS). The nuclear membrane consists of a double unit-type membrane which is perforated by a number of pores; the outermost membrane is continuous with the ENDOPLASMIC RETICULUM. A cell may contain more than one nucleus. (From Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed)
Active Transport, Cell Nucleus
Gated transport mechanisms by which proteins or RNA are moved across the NUCLEAR MEMBRANE.
Nucleus Accumbens
Collection of pleomorphic cells in the caudal part of the anterior horn of the LATERAL VENTRICLE, in the region of the OLFACTORY TUBERCLE, lying between the head of the CAUDATE NUCLEUS and the ANTERIOR PERFORATED SUBSTANCE. It is part of the so-called VENTRAL STRIATUM, a composite structure considered part of the BASAL GANGLIA.
Thalamic Nuclei
Several groups of nuclei in the thalamus that serve as the major relay centers for sensory impulses in the brain.
Solitary Nucleus
GRAY MATTER located in the dorsomedial part of the MEDULLA OBLONGATA associated with the solitary tract. The solitary nucleus receives inputs from most organ systems including the terminations of the facial, glossopharyngeal, and vagus nerves. It is a major coordinator of AUTONOMIC NERVOUS SYSTEM regulation of cardiovascular, respiratory, gustatory, gastrointestinal, and chemoreceptive aspects of HOMEOSTASIS. The solitary nucleus is also notable for the large number of NEUROTRANSMITTERS which are found therein.
Cell Nucleus Shape
The quality of surface form or outline of the CELL NUCLEUS.
Cytoplasm
The part of a cell that contains the CYTOSOL and small structures excluding the CELL NUCLEUS; MITOCHONDRIA; and large VACUOLES. (Glick, Glossary of Biochemistry and Molecular Biology, 1990)
Cochlear Nucleus
The brain stem nucleus that receives the central input from the cochlear nerve. The cochlear nucleus is located lateral and dorsolateral to the inferior cerebellar peduncles and is functionally divided into dorsal and ventral parts. It is tonotopically organized, performs the first stage of central auditory processing, and projects (directly or indirectly) to higher auditory areas including the superior olivary nuclei, the medial geniculi, the inferior colliculi, and the auditory cortex.

FISH analysis of six chromosomes in unfertilized human oocytes after polar body removal. (1/173)

PURPOSE: To develop an improved technique for estimating chromosomal abnormalities in human oocytes by fluorescence in situ hybridization (FISH) and to correlate the position of single chromatids with the chromosomal status of the oocytes. METHODS: Oocytes that were at metaphase II about 17-20 hr after insemination or intracytoplasmic sperm injection (ICSI) were treated with pronase to remove the zona pellucida and polar body (PB) and then spread on slides using HCl and Tween 20. Two rounds of FISH were performed using direct-labeled probes: chromosomes 1, 13, 21 (round 1); chromosomes X, 7, 18 (round 2). RESULTS: Of the 63 oocytes from 18 patients (mean age, 32 years), 48 (76%) had one DNA complement as expected, 9 (14%) had 2 DNA complements, 3 (5%) gave incomplete FISH signals, and 3 (5%) were not analyzable. Of the 48 oocytes with one set of DNA, 48% were haploid, 44% were aneuploid for one or more chromosomes, and 8% were polyploid. We also found an increased frequency of predivision of chromatid bivalents in aneuploid oocytes, especially for chromosome 21. CONCLUSIONS: This technique enables simultaneous assessment of six chromosomes in human oocytes, and therefore can be useful for accurately determining the incidence and causes of genetic imbalances in human oocytes and apparently low fertilization rates.  (+info)

Formation of nuclear HSF1 granules varies depending on stress stimuli. (2/173)

In concert with the stress-induced activation of human heat shock factor 1 (HSF1), the factor becomes inducibly phosphorylated and accumulates into nuclear granules. To date, these processes are not fully understood. Here, we show that although stress caused by the proteasome inhibitors MG132 and clasto-lactacystine beta-lactone induces the expression of Hsp70, the formation of HSF1 granules is affected differently in comparison to heat shock. Furthermore, proteasome inhibition increases serine phosphorylation on HSF1, but to a lesser extent than heat stress. Our results suggest that, depending on the type of stress stimulus, the multiple events associated with HSF1 activation might be affected differently.  (+info)

ICP0 induces the accumulation of colocalizing conjugated ubiquitin. (3/173)

Herpes simplex virus type 1 (HSV-1) immediate-early protein ICP0 is a general activator of viral gene expression which stimulates the initiation of lytic infection and reactivation from quiescence and latency. The importance of ICP0 to the biology of HSV-1 infection has stimulated interest in its mode of action. Previous studies have reported its interactions with other viral regulatory molecules, with the translation apparatus, with cyclin D3, and with a ubiquitin-specific protease. It has been demonstrated that ICP0 is able to induce the proteasome-dependent degradation of a number of cellular proteins, including components of centromeres and small nuclear substructures known as ND10 or PML nuclear bodies. ICP0 has a RING finger zinc-binding domain which is essential for its functions. In view of several recent examples of other RING finger proteins which modulate the stability of specific target proteins by acting as components of E3 ubiquitin ligase complexes, this study has explored whether ICP0 might operate via a similar mechanism. Evidence that the foci of accumulated ICP0 in transfected and infected cells contain enhanced levels of conjugated ubiquitin is presented. This effect was dependent on the RING finger region of ICP0, and comparison of the properties of a number of ICP0 mutants revealed an excellent correlation between previously established functions of ICP0 and its ability to induce concentrations of colocalizing conjugated ubiquitin. These results strongly support the hypothesis that a major factor in the mechanism by which ICP0 influences virus infection is its ability to induce the degradation of specific cellular targets by interaction with the ubiquitin-proteasome pathway.  (+info)

Alphaherpesvirus proteins related to herpes simplex virus type 1 ICP0 affect cellular structures and proteins. (4/173)

The herpes simplex virus type 1 (HSV-1) immediate-early protein ICP0 interacts with several cellular proteins and induces the proteasome-dependent degradation of others during infection. In this study we show that ICP0 is required for the proteasome-dependent degradation of the ND10 protein Sp100 and, as with the other target proteins, the ICP0 RING finger domain is essential. Further, comparison of the kinetics and ICP0 domain requirements for the degradation of PMI and Sp100 suggests that a common mechanism is involved. Homologues of ICP0 are encoded by other members of the alphaherpesvirus family. These proteins show strong sequence homology to ICP0 within the RING finger domain but limited similarity elsewhere. Using transfection assays, we have shown that all the ICP0 homologues that we tested have significant effects on the immunofluorescence staining character of at least one of the proteins destabilized by ICP0, and by using a recombinant virus, we found that the equine herpesvirus ICP0 homologue induced the proteasome-dependent degradation of endogenous CENP-C and modified forms of PML and Sp100. However, in contrast to ICP0, the homologue proteins had no effect on the distribution of the ubiquitin-specific protease USP7 within the cell, consistent with their lack of a USP7 binding domain. We also found that ICP0 by itself could induce the abrogation of SUMO-1 conjugation and then the proteasome-dependent degradation of unmodified exogenous PML in transfected cells, thus demonstrating that other HSV-1 proteins are not required. Surprisingly, the ICP0 homologues were unable to cause these effects. Overall, these data suggest that the members of the ICP0 family of proteins may act via a similar mechanism or pathway involving their RING finger domain but that their intrinsic activities and effects on endogenous and exogenous proteins differ in detail.  (+info)

DNA replication progresses on the periphery of nuclear aggregates formed by the BCL6 transcription factor. (5/173)

The BCL6 proto-oncogene, frequently alterated in non-Hodgkin lymphoma, encodes a POZ/zinc finger protein that localizes into discrete nuclear subdomains. Upon prolonged BCL6 overexpression in cells bearing an inducible BCL6 allele (UTA-L cells), these subdomains apparently coincide with sites of DNA synthesis. Here, we explore the relationship between BCL6 and replication by both electron and confocal laser scanning microscopy. First, by electron microscope analyses, we found that endogenous BCL6 is associated with replication foci. Moreover, we show that a relatively low expression level of BCL6 reached after a brief induction in UTA-L cells is sufficient to observe its targeting to mid, late, and at least certain early replication foci visualized by a pulse-labeling with bromodeoxyuridine (BrdU). In addition, when UTA-L cells are simultaneously induced for BCL6 expression and exposed to BrdU for a few hours just after the release from a block in mitosis, a nuclear diffuse BCL6 staining indicates cells in G(1), while cells in S show a more punctate nuclear BCL6 distribution associated with replication foci. Finally, ultrastructural analyses in UTA-L cells exposed to BrdU for various times reveal that replication progresses just around, but not within, BCL6 subdomains. Thus, nascent DNA is localized near, but not colocalized with, BCL6 subdomains, suggesting that they play an architectural role influencing positioning and/or assembly of replication foci. Together with its previously function as transcription repressor recruiting a histone deacetylase complex, BCL6 may therefore contribute to link nuclear organization, replication, and chromatin-mediated regulation.  (+info)

The matrix protein of vesicular stomatitis virus inhibits nucleocytoplasmic transport when it is in the nucleus and associated with nuclear pore complexes. (6/173)

The matrix (M) protein of vesicular stomatitis virus (VSV) is a potent inhibitor of bidirectional nuclear transport. Here we demonstrate that inhibition occurs when M protein is in the nucleus of Xenopus laevis oocytes and that M activity is readily reversed by a monoclonal antibody (alphaM). We identify a region of M protein, amino acids 51 to 59, that is required both for inhibition of transport and for efficient recognition by alphaM. When expressed in transfected HeLa cells, M protein colocalizes with nuclear pore complexes (NPCs) at the nuclear rim. Moreover, mutation of a single amino acid, methionine 51, eliminates both transport inhibition and targeting to NPCs. We propose that M protein inhibits bidirectional transport by interacting with a component of the NPC or an NPC-associated factor that participates in nucleocytoplasmic transport.  (+info)

Essential roles for Caenorhabditis elegans lamin gene in nuclear organization, cell cycle progression, and spatial organization of nuclear pore complexes. (7/173)

Caenorhabditis elegans has a single lamin gene, designated lmn-1 (previously termed CeLam-1). Antibodies raised against the lmn-1 product (Ce-lamin) detected a 64-kDa nuclear envelope protein. Ce-lamin was detected in the nuclear periphery of all cells except sperm and was found in the nuclear interior in embryonic cells and in a fraction of adult cells. Reductions in the amount of Ce-lamin protein produce embryonic lethality. Although the majority of affected embryos survive to produce several hundred nuclei, defects can be detected as early as the first nuclear divisions. Abnormalities include rapid changes in nuclear morphology during interphase, loss of chromosomes, unequal separation of chromosomes into daughter nuclei, abnormal condensation of chromatin, an increase in DNA content, and abnormal distribution of nuclear pore complexes (NPCs). Under conditions of incomplete RNA interference, a fraction of embryos escaped embryonic arrest and continue to develop through larval life. These animals exhibit additional phenotypes including sterility and defective segregation of chromosomes in germ cells. Our observations show that lmn-1 is an essential gene in C. elegans, and that the nuclear lamins are involved in chromatin organization, cell cycle progression, chromosome segregation, and correct spacing of NPCs.  (+info)

A chromatin insulator determines the nuclear localization of DNA. (8/173)

Chromatin insulators might regulate gene expression by controlling the subnuclear organization of DNA. We found that a DNA sequence normally located inside of the nucleus moved to the periphery when the gypsy insulator was placed within the sequence. The presence of the gypsy insulator also caused two sequences, normally found in different regions of the nucleus, to come together at a single location. Alterations in this subnuclear organization imposed by the gypsy insulator correlated with changes in gene expression that took place during the heat-shock response. These global changes in transcription were accompanied by dramatic alterations in the distribution of insulator proteins and DNA. The results suggest that the nuclear organization imposed by the gypsy insulator on the chromatin fiber is important for gene expression.  (+info)

Although bystin has been identified as a protein potentially involved in - GLO1 inhibitors for neuropsychiatricAlthough bystin has been identified as a protein potentially involved in - GLO1 inhibitors for neuropsychiatric
Although bystin has been identified as a protein potentially involved in embryo implantation (a process unique to mammals) in humans the bystin gene is evolutionarily conserved from yeast to humans. by RNAi (RNA interference). Pulse-chase analysis of ribosomal RNA processing suggested that bystin knockdown delays processing of 18S ribosomal RNA a component of the 40S subunit. Furthermore this knockdown significantly inhibited cell S(-)-Propranolol HCl proliferation. Our findings suggest that bystin may promote cell proliferation by facilitating ribosome biogenesis specifically in the production of the 40S subunit. Localization of bystin to the nucleolus the site of ribosome biogenesis was blocked by S(-)-Propranolol HCl low concentrations of actinomycin D a reagent that causes nucleolar stress. When bystin was transiently overexpressed in HeLa cells subjected to nucleolar stress nuclear bystin was included in particles different from the nuclear stress granules induced by heat shock.

DISEASES - PML
PML [ENSP00000268058]. Tripartite motif-containing protein 19; Functions via its association with PML-nuclear bodies (PML-NBs) in a wide range of important cellular processes, including tumor suppression, transcriptional regulation, apoptosis, senescence, DNA damage response, and viral defense mechanisms. Acts as the scaffold of PML-NBs allowing other proteins to shuttle in and out, a process which is regulated by SUMO-mediated modifications and interactions. Isoform PML-4 has a multifaceted role in the regulation of apoptosis and growth suppression: activates RB1 and inhibits AKT1 via interactions with PP1 and PP2A phosphatases respectively, negatively affects the PI3K pathway by inhibiting MTOR and activating PTEN, and positively regulates p53/TP53 by acting at different levels (by promoting its acetylation and phosphorylation and by inhibiting its MDM2-dependent degradation). Isoform PML-4 also: acts as a transcriptional repressor of TBX2 during cellular senescence and the repression is ...

Cardiolite is a nuclear radioactive isotope termed Technetium Tc99m Sestamibi. Cardiolite is injected through an IV and it travels in the bloodstream and through the coronary arteries until it is picked up by the heart muscle cells. The areas of the heart that have an adequate blood supply pick up the tracer right away and more completely. Areas that do not have adequate blood supply pick up the tracer very slowly or not at all.. Cardiolite gives off a small amount of radiation that is detected with a nuclear scanning camera. A computer processes the information and produces the images of the radioactivity distributed in the heart.. If an area receives less blood than the rest of the heart (because of a blocked or narrowed artery), it will pick up a lower level of radioactivity and will show up as a lighter area, called a defect.. Cardiolite is injected while you are at rest and while your heart is under stress. Rest and stress images are taken to allow doctors to compare how much blood flows ...

In answer to some questions on your forum on how I found out that my heart was clear from plaque.:::: I had a Nuclear Stress test late in 2006 that showed my heart in real distress. The pictures that the test recorded, showed that my hearts arteries were nearly completely darkened in by plaque. This means that the arteries were all clogged, i.e., getting very little oxygen. My doctor said that I needed a bypass or a stent and must start on statin drugs immediately. I turned it all down. Needless to say he was really worried. I was very sick...couldnt walk far or fast, out of breath, blue feet...I felt like I was dying. Sooooo I started taking the Linus Pauling cure that I had been reading about... smile...

The entire test will take approximately four to six hours, although you will be walking on the treadmill for approximately 10 minutes of that time. An IV will be started in your arm, and a small dose of radioactive isotope will be injected. After this injection, you will be asked to wait approximately 45 minutes to allow this material to be taken up by your heart cells. After the 45-minute wait time, you will lie on a scanning table and a special camera (gamma camera) will be positioned close to your chest, and you will be asked to lie still. The gamma camera takes pictures of your heart. This part of the test takes approximately 10-15 minutes. The stress laboratory is equipped with a Philips ADAC Cardio MD dual head camera.. After the image session, a specially-trained nurse will place electrodes on your chest, and wires will be attached to the electrodes so that the electrocardiogram (ECG) can be monitored continuously during the test.

In recent years, by RNA sequencing and annotation by the GENECODE project, thousands of lncRNAs have been discovered, the functions of which have not been established. EGFR module/PDGFR module-based glioma classification forms a framework towards establishing molecular diagnostic tools and identifying novel therapeutic targets to combat gliomas (5). These results indicate that NEAT1 functions as an oncogene in glioblastoma. In this study, we compared the lncRNA profiles of glioma tissues from different grades using public data sets. We discovered that the lncRNA NEAT1 was driven by EGFR pathway activity. NEAT1 is an essential architectural component of paraspeckle nuclear bodies. The tumor anoxia microenvironment can activate NEAT1 and induce nuclear paraspeckle formation through HIF-2α, leading to breast cancer cell survival (10). In prostate cancer, NEAT1 has an oncogenic character and alters the epigenetic landscape of target gene promoters to favor transcription (37). NEAT1 showed the ...

Nuclear speckles are self-assembled organelles composed of RNAs and proteins. They are proposed to act as structural domains that control distinct steps in gene expression, including transcription, splicing, and mRNA export. Earlier studies identified differential localization of a few components within the speckles. It was speculated that the spatial organization of speckle components might contribute directly to the order of operations that coordinate distinct processes. By performing multi-color structured illumination microscopy, we characterized the multilayer organization of speckles at a higher resolution. SON and SC35 localize to the central region of the speckle, whereas MALAT1 and snRNAs are enriched towards the speckle periphery. Coarse-grained simulations indicate that the non-random organization arises due to the interplay between favorable, sequence-encoded intermolecular interactions of speckle-resident proteins and RNAs. Finally, we observe positive correlation between the total ...

RBM45 interactors. RBM45 monomers assemble into multimers that associate with TDP-43 via a bridging RNA. Multimers may end up in stress granules in the cytoplasm, or stress bodies in the nucleus. [Courtesy of Li et al., Scientific Reports.] What about interactions with other proteins? Li has not yet examined nuclear stress bodies but did study how RBM45 interacts with TDP-43 in the cytoplasm. The two proteins co-immunoprecipitated-but not, however, if Li treated the cells with RNase. She thinks they may bind and co-regulate the same transcripts. Because RBM45 also needed the HOA to associate with TDP-43, Li thinks RBM45 must bind RNAs as an oligomer. The researchers are now trying to identify the RNAs that bind both RBM43 and TDP-43 (Li et al., 2015).. In another recent paper, Bowser and colleagues focused on the cytoplasmic activities of RBM45. They found that like TDP-43 and FUS, it moved from the nucleus to the cytoplasm in cultured motor neurons that were undergoing oxidative stress. There, ...

ECG electrodes will be attached to your chest. The electrodes are small, sticky patches with wires. Your resting blood pressure and ECG readings will be taken.. The cardiac stress test is done on a treadmill or a stationary bike. You will slowly start walking or riding. At regular intervals, the speed and elevation will be increased. Your ECG, blood pressure, heart rate, and symptoms will be closely monitored.. The test may be stopped early if you feel extremely tired, get chest pain, have trouble breathing, or if you have any symptoms that suggest heart problems. Significant changes in the ECG will also stop the test. After exercise is complete, your blood pressure, heart rate, and ECG will be monitored until levels return to normal.. A blood flow imaging exam may also be ordered. This is called a nuclear stress test. A small amount of radioactive chemical will be injected into a vein when you are exercising at your peak.

Notes from Dr. RW: January 2015Notes from Dr. RW: January 2015
While regadenoson has become the vasodilator stress agent of choice and has streamlined and simplified stress protocols in many nuclear stress laboratories, the adverse effect of dyspnea is still experienced by many patients, and even more so by those with COPD and asthma. While patients and practitioners should anticipate this symptom, several studies have shown that the subjective experience of dyspnea is not correlated with and is not caused by bronchoconstriction. Available data from observational studies as well as controlled clinical trials, as summarized in Table 1, indicate that the use of regadenoson in patients with mild to moderate asthma and mild to moderate COPD is safe. The current data in patients with severe COPD, while limited, are reassuring and indicate that regadenoson is probably safe, particularly in those with stable lung disease. Clinical data are limited in COPD patients who require 24-hour/day home oxygen administration, have previously been intubated for respiratory ...

US Scientists take a new look at nuclear stress - The Engineer The EngineerUS Scientists take a new look at nuclear stress - The Engineer The Engineer
Scientists at the US Department of Energys Pacific Northwest National Laboratory have performed first-of-a-kind, high-resolution examinations of cracks in stainless steel core components from commercial nuclear reactors, dispelling many of the traditionally held beliefs about how cracks develop and spread.. According to the DOE, it has been long held that cracks in nuclear reactor components are the result of alloy embrittlement or local changes to the water environment caused by radiation. With the use of analytical electron microscopy and a new approach to access buried corrosion interfaces for study, however, Larry Thomas and Steve Bruemmer have discovered that the crack advance is promoted by radiation-enhanced, corrosion-induced material changes ahead of the tip of the crack.. While cracking of metal components inside nuclear reactors has been a continuing problem over many years, the ability to directly evaluate cracking mechanisms has been limited. Most research has been performed ...

Tumor hypoxia induces nuclear paraspeckle formation through HIF-2α dependent transcriptional activation of NEAT1 leading to cancer cell survival. Oncogene, 34 (34), pp. 4482-4490. , Show Abstract , Read more Activation of cellular transcriptional responses, mediated by hypoxia-inducible factor (HIF), is common in many types of cancer, and generally confers a poor prognosis. Known to induce many hundreds of protein-coding genes, HIF has also recently been shown to be a key regulator of the non-coding transcriptional response. Here, we show that NEAT1 long non-coding RNA (lncRNA) is a direct transcriptional target of HIF in many breast cancer cell lines and in solid tumors. Unlike previously described lncRNAs, NEAT1 is regulated principally by HIF-2 rather than by HIF-1. NEAT1 is a nuclear lncRNA that is an essential structural ...

Antisense protein of HTLV-2 (APH-2) associates with PML nuclear bodies: molecular determinants and functional implications |...Antisense protein of HTLV-2 (APH-2) associates with PML nuclear bodies: molecular determinants and functional implications |...
Antisens Protein of HTLV-2 (APH-2) was described in 2009. APH-2 mRNA is expressed in vivo in most HTLV-2 carriers. In recent years, several laboratories have searched for similarities and/or differences between APH-2 and the antisens protein of HTLV-1, HBZ. Similarly to HBZ, APH-2 negatively regulates HTLV-2 transcription. However, it does not promote cell proliferation. In vivo, APH-2 localizes in discrete nuclear domains distinct from nucleoli. We therefore characterized APH-2 subcellular localization, in order to decipher the determinants of such localization and to correlate it or not with APH-2 functions. We first identify APH-2-containing nuclear domains as PML nuclear bodies (PML-NB). PML-NB are modulators of a number of cellular processes ranging from transcription regulation to cell proliferation and death. We show that both an in silico-identified nuclear localization signal and the carboxy-terminal LXXLL motif contribute to APH-2 targeting to PML-NB. Covalent modification of APH-2 by ...

Dr. Wes: Living With Atrial FibrillationDr. Wes: Living With Atrial Fibrillation
Dr Wes--I consider myself fortunate, as a 56 yr male paroxysmal ATF patient (primarily nocturnal & highly symptomatic; prevented me from sleeping), to have had good luck with flecainide, 100mg daily. It took me a while to determine that there are 2 types of cardiologists: plumbers and electricians. Once I determined that I needed what I found out was your specialty, a Cardiac Electrophysiologist, and once my doctor got a good capture on a Holter Monitor, he prescribed the flecainide after the nuclear stress test and an echocardiogram, and I never looked back. Five years later, and a second stress test, no problems. Hopefully the medication, which is thankfully generic, will continue to work well. For me, at least, its a triumph of modern pharmacology. I enjoy your commentary on this blog; youve referred me to a number of informative sources that have helped educate this engineer as to what ATF is all about. Keep up the great work! ...

I had a bad feeling about my HR, whilst I do about an hour of cardio a day I still am not unusually athletic by any stretch of the imagination…so I went to my GP. They did an EKG which showed multiple PVCs…early heartbeats that do not show up on a regular heart rate monitor. This meant that my HR readings of 40-50 bpm are way off. Apparently pvcs are extremely common, effecting about 2/3rds of us, although most are only getting a couple of hundred a day. My doctor said pvcs are nothing to worry about and I still had a good resting heartrate of about 65 when pvcs are accounted for. However because my father had a heart attack at 58 he referred me to a cardiologist. The cardiologist has done a stress test, a halter monitor test, a nuclear stress test, ekgs bloodwork/cholesterol (which is fantastic - yay me) and an echo.

Nuclear stress test utilizes nuclear isotope (most commonly Cardiolite) which traces blood flow to the heart. This nuclear tracer in the blood is taken up by heart muscle in proportion to coronary blood flow, i.e., normal uptake if the flow is intact and less uptake if the flow is reduced due to coronary blockage. This blood flow pattern is shown by nuclear camera which scans the small amount of radioactivity emitted by the isotope taken up by heart tissue. Hence the test is primarily designed to detect signs of coronary artery disease. This isotope is well-tolerated by most and is cleared from the body in 24 to 36 hours.. This is carried out in two parts: stress images and resting images. The stress part can be done with treadmill stress test or chemical stress test (most commonly Lexiscan or Persantine) if you cannot physically exercise. At peak exercise or following injection of Lexiscan, Cardiolite is injected and the patient is scanned under the nuclear camera. The resting images are also ...

Promyelocytic leukemia (PML) bodies are nuclear multi-protein domains. The observations that viruses transcribe their genomes adjacent to PML bodies and that nascent RNA accumulates at their periphery suggest that PML bodies function in transcription. We have used immuno-FISH in primary human fibroblasts to determine the 3D spatial organisation of gene-rich and gene-poor chromosomal regions relative to PML bodies. We find a highly non-random association of the gene-rich major histocompatibilty complex (MHC) on chromosome 6 with PML bodies. This association is specific for the centromeric end of the MHC and extends over a genomic region of at least 1.6 megabases. We also show that PML association is maintained when a subsection of this region is integrated into another chromosomal location. This is the first demonstration that PML bodies have specific chromosomal associations and supports a model for PML bodies as part of a functional nuclear compartment ...
