Chronic alcoholism decreases neuronal nuclear size in the human entorhinal cortex


The effect of chronic alcoholism in the neuronal nuclear area (karyometry) of the lateral entorhinal cortex at three rostro-caudal levels (rostral, intermediate and caudal) has been studied in 19 alcoholic subjects and in 15 aged-matched controls. Cases were distributed into three groups according to their age (29–44, 45–60 and 61–70 years of age). In the second group (45–60 years), the nuclear size in layers II and III of the caudal entorhinal cortex showed a very significant decrease compared to controls. The first group (29–44 years) also showed a significant reduction in size, while the third group presented the smallest differences. The presence of cirrhosis in the alcoholic group did not vary the observed results. Thus, chronic alcoholism significantly decreases the nuclear size in layers II and III of the lateral entorhinal cortex, and thus the entorhinal output to the hippocampus may be altered in alcoholism.

Mutation analysis of the PTEN/MMAC1 gene in lung cancer


We studied PTEN/MMAC1, a newly discovered candidate tumor suppressor gene at 10q23.3, for mutations in lung cancer. One hundred and thirty-six lung cancer cell line DNAs (66 small cell lung cancers, SCLC, 61 non-small cell lung cancers, NSCLC, four mesotheliomas, five extrapulmonary small cell cancers) were analysed for PTEN/MMAC1 homozygous deletions and five (8%) SCLC lines showed homozygous deletions interrupting the PTEN/MMAC1 gene. Using single stranded conformation polymorphism (SSCP) analysis, we screened the PTEN/MMAC1 open reading frame of 53 lung cancer cell line cDNAs for point mutations and found that 3/35 SCLCs and 3/18 NSCLCs contained homozygous amino acid sequence altering mutations. Northern blot analysis revealed that expression of the PTEN/MMAC1 gene was considerably lower in all the tumor cell lines with point mutations while no expression was detected for cell lines with PTEN/MMAC1 homozygous deletions. Mutation analysis of 22 uncultured, microdissected, primary SCLC tumors and metastases showed two silent mutations, and two apparent homozygous deletions. We also discovered a processed pseudogene (PTEN2) which has 98.5% nt identity to PTEN/MMAC1, that needs to be accounted for in cDNA mutation analysis. Our findings suggest that genetic abnormalities of the PTEN/MMAC1 gene are only involved in a relatively small subset of lung cancers.

Learn Secreted frizzled related protein 1 knowledge


Secreted frizzled-related protein 1 (SFRP1) is a member of the SFRP family that contains a cysteine-rich domain homologous to the putative Wnt-binding site of Frizzled proteins. SFRPs act as soluble modulators of Wnt signaling. SFRP1 and SFRP5 may be involved in determining the polarity of photoreceptor cells in the retina. SFRP1 is expressed in several human tissues, with the highest levels in heart.
The Secreted frizzled-related protein (SFRP) family consists of five secreted glycoproteins in humans (SFRP1, SFRP2, SFRP3, SFRP4, SFRP5) that act as extracellular signaling ligands. Each SFRP is ~ 300 amino acids in length and contains a cysteine-rich domain (CRD) that shares 30-50% sequence homology with the CRD of Frizzled (Fz) receptors. SFRPs are able to bind Wnt proteins and Fz receptors in the extracellular compartment. The interaction between SFRPs and Wnt proteins prevents the latter from binding the Fz receptors. SFRPs are also able to downregulate Wnt signaling by the formation of an inhibitory complex with the Frizzled receptors The Wnt pathway plays a key role in embryonic development, cell differentiation and cell proliferation. It has been shown that the deregulation of this critical developmental pathway occurs in several human tumor entities.
SFRP1 is a 35 kDa prototypical member of the SFRP family. It acts as a biphasic modulator of Wnt signaling, counteracting Wnt-induced effects at high concentrations and promoting them at lower concentrations. It is located in a chromosomal region (8p12-p11.1 ) that is frequently deleted in breast cancer and is thought to harbour a tumor suppressor gene.

Silymarin extract with Special Antioxidant Benefits


Silymarin refers to three active flavonoid components of milk thistle: primarily silybin with smaller amounts of silydianin and silychristin. This trio neutralizes toxins and improves liver function. Its action rests primarily upon the ability to inhibit production and activity of hepatotoxic (liver toxic) compounds. More recent evidence indicates that it benefits the health of several other organs as well.
The liver is the primary organ for detoxification. Many toxins are either free radicals, or encourage free radical production and may subsequently interfere with the liver's defenses against free radicals. As a potent antioxidant, silymarin intervenes in free radical generation and protects against many reactive oxygen species.In some measurement systems, silymarin is ten times more effective than vitamin E in preventing unwanted oxidation. The extract also increases the liver's content of the antioxidant enzyme glutathione (GSH) by ~35 percent, and increases the levels of the body's major antioxidant enzyme, superoxide dismutase (SOD). Silymarin also modulates the actions of lipoxygenase in the liver. Lipoxygenase acts upon polyunsaturated fatty acids to produce pro-inflammatory compounds called leukotrienes, which cause damage to liver cell membranes.
Silymarin is active against all of these assaults upon liver cell integrity and function. It therefore has direct and indirect antioxidant benefits by elevating the body's own defenses. Research has shown that milk thistle extracts also significantly enhance cellular immune biomarkers.

Tetrandrine anti angina pectoris



Tetrandrine on animal papillary muscle, from heart and cardiovascular aspects such as the aorta is present different pharmacological effects. The animal experiments found that the drug can reduce the myocardial contraction force, slow cardiac frequency, the expansion of the peripheral blood vessels, reduce the peripheral resistance, reduce cardiac afterload and reduce the myocardial oxygen consumption, inhibition of excited a vascular smooth muscle contraction coupling and relaxation. To animals left atrium muscle contraction frequency dependence and membrane potential dependent inhibition, and have significantly reduced the animal heart strong muscle cell action potential schedule, for the slow response action potential amplitude and time history has obvious inhibitory effect. Through the contrast experiments show that the above function and the effect of slow channel blockers verapamil is extremely similar, this effect was dose and time dependent. When the concentration of 30 umoi/umol/L and 100 L, 100 min after the treatment, slow inward current peak respectively by dosing before 47.9 + / - 5.6 nA and 38.4 + / - 21.5 nA fell to 21 nA + / - 7.8 and 6.3 + / - 7.7 nA, p0.01, R if use Tetrandrine100umol/L of mediated by divalent cations Sr2 + slow inward current also has obvious inhibitory effect. The results suggest that Tetrandrine is a good slow channel blockers.

A brief introduction IGF1-R ELISA Kit



To acknowledge the IGF1 acuteness of breast tumors we detected IGF1-R with a biochemical appraisal (RRA). We again localized and quantified IGF1-R on arctic tissue sections by histo-autoradiographic assay (HAA). In some cases, the IGF1 and IGF1-R mRNA announcement were advised by Northern blemish analysis. We aswell advised the IGF1 claret absorption in primary breast cancers compared to controls. IGF1-R (RRA) were begin in 87% (n = 297) of the breast cancers. The beggarly geometric amount was 3.87% (specific bounden as allotment of absolute radioactivity); we begin a awful cogent alternation amid IGF1-R and ER on the one duke (P = 0.0001) and PgR on the added (P = 0.0001) (Spearman test). The attendance of IGF1-R was associated with a bigger prognosis, either on relapse-free adaptation (actuarial analysis: P = 0.004; Cox analysis: P = 0.005) or all-embracing adaptation (respectively P = 0.003; P = 0.005). The average continuance of aftereffect was 30 months. By Cox assay IGF1-R was a bigger anxiety agency than ER and PgR. In a alternation of 77 cases of amiable breast ache alone 47% (36/77) were positive; the beggarly geometric akin was 1.8%. The HAA IGF1-R altitude in 20 breast carcinomas and 12 cases of amiable breast ache accepted the RRA after-effects and approved that the labeling was localized on the epithelial component. In four breast cancers, we did not ascertain IGF1 mRNA; IGF1-R delving approved two above mRNAs of 11 and 7 kB. Finally we begin that IGF1 claret akin was college in breast blight patients than in advantageous controls of the aforementioned age. These after-effects appearance that IGF1 is active in breast blight advance and advance that anti-IGF1 analysis ability be advantageous in animal breast cancer: for this reason, we and others agitated out a appearance II analytic balloon with somatostatin.

The introduction of the HBMEC


Most cases of neonatal bacterial meningitis advance as a aftereffect of a hematogenous spread, but it is not bright how circulating bacilli cantankerous the blood-brain barrier. Attempts to acknowledgment these questions accept been bedfast by the abridgement of a reliable archetypal of the animal blood-brain barrier. Human brain microvascular endothelial cells(HBMEC) were abandoned and transfected with a pBR322 based plasmid absolute simian virus 40 ample T antigen (SV40-LT). The transfected HBMEC apparent agnate academician endothelial corpuscle characteristics as the primary HBMEC, i.e. gamma glutamyl transpeptidase and a top transendothelial electrical resistance. Escherischia coli and Citrobacter spp, two important Gram-negative bacilli causing neonatal meningitis, were begin to transcytose beyond primary and transfected HBMEC, after affecting the candor of the monolayer. In addition, E. coli and C. freundii invaded transfected HBMEC as apparent ahead with primary HBMEC. We achieve that E. coli and C. freundii are able to access and transcytose HBMEC and these bacterial-HBMEC interactions are agnate amid primary and transfected HBMEC. Therefore, our transfected HBMEC should be advantageous for belief pathogenesis of CNS infections.

In the presence of biological phospholipids, phosphatidylethanolamine (Cephalin) after the lecithin content, in E. coli, and it accounts for about 80% of the total phospholipids. Each fatty acid composition varies due to biological, microbiological and yolk saturated fatty acid composition than animal tissue. Still exist in the biosphere containing monomethyl amine, dimethyl amine derivatives. All these make the S-adenosylmethionine and methylation of phosphatidylethanolamine is formed, E. P. Ke-nnedy etc. (1956,1964) demonstrated in microorganisms, phosphatidyl ethanolamine by decarboxylation phosphatidyl serine formed. In animals, it is through the CDP ethanolamine and 1,2 - diacylglycerol produced in the reaction. Generated by hemolysis phosphatidylethanolamine role of phospholipase A. It is very road, in rat liver, which together with the lecithin between microsomes and mitochondria be transferred.
