Candida albicans is among the most prevalent opportunistic fungal pathogens. Its capacity to cause life-threatening bloodstream infections is associated with the ability to form biofilms, which are intrinsically drug resistant reservoirs for dispersal. A key regulator of biofilm drug resistance and dispersal is the molecular chaperone Hsp90, which stabilizes many signal transducers. We previously identified 226 C. albicans Hsp90 genetic interactors under planktonic conditions, of which 56 are involved in transcriptional regulation. Six of these transcriptional regulators have previously been implicated in biofilm formation, suggesting that Hsp90 genetic interactions identified in planktonic conditions may have functional significance in biofilms. Here, we explored the relationship between Hsp90 and five of these transcription factor genetic interactors BCR1, MIG1, TEC1, TUP1, and UPC2. We deleted each transcription factor gene in an Hsp90 conditional expression strain, and assessed biofilm formation and morphogenesis. Strikingly, depletion of Hsp90 conferred no additional biofilm defect in the mutants. An interaction was observed in which deletion of BCR1 enhanced filamentation upon reduction of Hsp90 levels. Further, although Hsp90 modulates expression of TEC1, TUP1, and UPC2 in planktonic conditions, it has no impact in biofilms. Lastly, we probed for physical interactions between Hsp90 and Tup1, whose WD40 domain suggests that it might interact with Hsp90 directly. Hsp90 and Tup1 formed a stable complex, independent of temperature or developmental state. Our results illuminate a physical interaction between Hsp90 and a key transcriptional regulator of filamentation and biofilm formation, and suggest that Hsp90 has distinct genetic interactions in planktonic and biofilm cellular states.
To identify appropriate dimensional items in objective diagnostic analysis for attractiveness of frontal posed smile in Japanese female patients by comparing with the result of human judgments.

Photographs of frontal posed smiles of 100 Japanese females after orthodontic treatment were evaluated by 20 dental students (10 males and 10 females) using a visual analogue scale (VAS). The photographs were ranked based on the VAS evaluations and the 25 photographs with the highest evaluations were selected as group A, and the 25 photos with the lowest evaluations were designated group B. Then 12 dimensional items of objective analysis selected from a literature review were measured. Means and standard deviations for measurements of the dimensional items were compared between the groups using the unpaired t-test with a significance level of P < .05.

Mean values were significantly smaller in group A than in group B for interlabial gap, intervermilion distance, maxillary gingival display, maximum incisor exposure, and lower lip to incisor (P < .05).

Significant differences were observed only in the vertical dimension, not in the transverse dimension. Five of the 12 objective diagnostic items were correlated with human judgments of the attractiveness of frontal posed smile in Japanese females after orthodontic treatment.

Lipopolysaccharide (LPS)/Endotoxin is hypothesized to play an important role in chronic inflammation associated with Type-1 diabetes (T1DM) and its complications. Endotoxin core antibodies (EndoCAb), LPS binding protein (LBP) and soluble CD14 (sCD14) act as modulators of LPS induced activation of innate immune system in vivo. For the present study we estimated the levels of LPS and its translocation markers in T1DM subjects with and without microvascular complications (MVC) and correlate them with clinical parameters of T1DM and serum inflammatory cytokine levels (TNF-α, IL-6, IL-1β and GM-CSF).

A total of 197 subjects (64 normal glucose tolerance (NGT) subjects, 97 T1DM subjects without MVC and 36 with MVC) were included in this study and the levels of serum LPS, its translocation markers and cytokines measured by immunoassays.

Compared to NGT, T1DM subjects (both with and without MVC) had significantly higher levels of LPS, reduced levels of LBP and EndoCAb along with significant increase in the levels of IL-1β, IL-6, TNF-α and GM-CSF (p<0.05). No significant change was seen in the levels of these biomarkers between T1DM subjects with and without MVC.

Decreased levels of EndoCAb and LBP suggest sustained endotoxin activity in T1DM subjects even before the onset of microvascular complications.

Endothelial dysfunction associated with many cardiovascular diseases is largely due to reduced nitric oxide (NO) derived from endothelial NO synthase (eNOS). Piceatannol (trans-3,4,3',5'-tetrahydroxystilbene; Pic) is reported to have cardiovascular therapeutic effects. However, the cellular and molecular mechanisms underlying the cardioprotective effects of Pic are still unclear. Here, we investigated whether Pic could influence endothelial NO release in human umbilical vein endothelial cells (HUVECs).

In HUVECs exposed to Pic, NO production and phosphorylation of eNOS and protein kinase B (Akt) were determined by using a commercially available NO assay kit and Western blot analysis, respectively.

Pic stimulated dose- and time-dependent NO production via eNOS phosphorylation. Pic also stimulated dose-dependent phosphorylation of Akt. Interestingly, NO production and eNOS phosphorylation in response to Pic were significantly abolished by the phosphoinositide 3-kinase (PI3K)/Akt inhibitor LY294002.

Pic is capable of inducing eNOS phosphorylation and the subsequent NO release, presumably, by activating PI3K/Akt pathway. The potential efficacy of Pic, a natural hydroxylated analog and a metabolite of resveratrol, may aid in the prevention of cardiovascular diseases characterized by endothelial dysfunction.

Non-alcoholic fatty liver disease (NAFLD) is an increasingly recognized health problem. Various treatment strategies such as thiazolidinediones, metformin, lipid-lowering agents and antioxidants have been evaluated. So far, no single intervention has convincingly improved liver histology. Experience of using silymarin alone or in combination with other agents in patients with NAFLD is limited in the medical literature. The present study was conducted to evaluate the efficacy of silymarin plus vitamin E in the treatment of NAFLD.

A sample of 36 patients was enrolled. The diagnosis of NAFLD was confirmed by percutaneous liver biopsy. All patients were randomized to one of the following intervention groups group I treated with 2 tablets per day of silymarin plus vitamin E (Eurosil 85®, MEDAS SL) and a lifestyle modification program consisting of hypocaloric diet (1520 kcal, 52% of carbohydrates, 25% of lipids and 23% of proteins) and exercise for 3 months and group II (only with the hypocaloric diet). Anthroograms.DIA-2 is a herbal mixture containing standardized extract of Allium sativum and Lagerstroemia speciosa. selleck Recently we have reported the anti-diabetic effect of DIA-2 in high fat diet (HFD) and streptozotocin (STZ) induced type 2 diabetic (T2D) rats. The purpose of this study was to investigate and compare the effects of DIA-2 with Rosiglitazone (RG) on plasma biomarkers of hepatocellular injury, liver carbohydrate metabolizing enzymes, glycogen content, oxidant/antioxidant status and histopathological changes in T2D rats. ALT and ALP levels were significantly decreased after DIA-2 and RG treatment compared to T2D rats. Total protein and albumin remained unaltered in all the groups. Significant decrease in AST levels were observed after DIA-2 (125 mg/kg) and RG treatment. Hepatic hexokinase activity was significantly increased after RG and DIA-2 treatment and fructose-1, 6-bisphosphatase activity were inversely correlated with hexokinase activity. Hepatic gucose-6-phosphatase activity was significantly (p less then 0.05) reduced after DIA-2 (62.5 mg/kg) and RG treatment. Lipid peroxides levels was significantly decreased in the liver of DIA-2 (62.5; p less then 0.01 & 125 mg/kg; p less then 0.05) treated animals. Hepatic glycogen content (p less then 0.05) and antioxidant enzymes [SOD (p less then 0.01; 62.5 mg/kg); GPx and GSH (125 mg/kg; p less then 0.01)] were significantly increased after DIA-2 treatment. RG treatment on hepatic glycogen, GPx (p less then 0.01) and SOD, GSH (p less then 0.05) levels were significant when compared to T2D rats. These biochemical parameters were also correlated with histopathological evaluation. The above findings revealed that administration of DIA-2 could ameliorate the biochemical and histopathological changes in liver of T2D rats indicating the protective role of DIA-2 against HFD/STZ induced diabetes. In addition, DIA-2 and RG treatment resulted in amelioration of hepatic steatosis in T2D rats.
We studied the association of single nucleotide polymorphisms (SNPs) rs7903146, rs12255372 and rs4506565 in type 2 diabetes mellitus (T2DM) susceptibility gene, transcription factor 7 like 2 (TCF7L2) with T2DM among the population of the Eastern Province of Saudi Arabia.

In a case-control study, blood samples were collected from 359 T2DM patients and 351 age and sex-matched normoglycemic controls. Genotyping was done by allele specific PCR assay.

Our results revealed a strong association between risk T alleles in variants rs12255372 (OR G/T=1.4233; T/T=2.0395) and rs4506565 (OR A/T=1.6066; T/T=3.1301) and T2DM among the Saudi population of the Eastern Province of Saudi Arabia. This is the first time that this association has been identified in a Saudi population. However, a common variant, rs7903146, often found to be associated with T2DM in other populations failed to demonstrate any association to T2DM with the present population. These data further strengthens the hypothesis that Saudi populations might carry a distinct risk allele in T2DM susceptibility gene TCF7L2.

The present results confirm that rs12255372 and rs4506565 variants of TCF7L2 show an association, but not rs7903146, with T2DM for the Saudi population of the Eastern Province of Saudi Arabia.

Invasive ductal carcinoma (IDC) comprises the largest group of breast cancers. This study aimed to investigate telomerase activity and apoptosis using immunohistochemical and Western blot methods.

In total, 75 cases that had been diagnosed as IDC and 20 cases that had undergone a freezing procedure were included. The histological sections were stained with Bax, Bcl-2, hTERT and BNIP3. The ages of the patients, as well as their hormonal status and tumour sizes and grades were evaluated, as well as the staining characteristics of the antibodies in question.

A decrease in Bcl-2 positivity and an increase in Bax positivity were found immunohistochemically with increasing tumour grades. The data obtained by western blot method showed that Bcl-2 was highest in grade 1 tumours although these results were not statistically significant. The relationship between estrogen and progesterone receptor positivity and Bcl-2 was statistically significant, suggesting there is hormonal control through apoptosis. BNIP3 was found to be decreased with increasing tumour grades.
