BACKGROUND Previous studies have confirmed that serum concentrations of actin-free Gc globulin (Af-Gc globulin) may provide prognostic information in patients withacute liver failure (ALF). However, until now the relation between plasma Af-Gc globulin levels and chronic or acute-on-chronic liver failure (CLF or ACLF) caused by HBV is unknown. METHODS Plasma Af-Gc globulin in 56 patients with ...

While the prognosis of gastric cancer (GC) remains poor, PD-1 and PD-L1/L2 are promising prognostic biomarkers. We evaluated PD-1 and PD-L1/L2 expression in tumor cells (TCs) and tumor-infiltrating immune cells (TIICs). We determined the Helicobacter pylori (Hp) and Epstein-Barr virus (EBV) infection status in a GC cohort (n=340), then analyzed the relationship between the expression of PD-1, P...

In this study, a simple and reliable method by gas chromatograph–mass spectrometry (GC–MS) was developed for the fast and regular identification of 3, 4-MDMA impurities in ecstasy tablets. In so doing, 8 samples of impurities were extracted by diethyl ether under alkaline condition and then analyzed by GC–MS. The results revealed high MDMA levels ranging from 37.6% to 57.7%. The GC-MS method sh...

AIM To evaluate associations between miRNA target genes IL12B, INSR, CCND1 and IL10 polymorphisms and gastric cancer (GC) in European population. METHODS Gene polymorphisms were analyzed in 508 controls and 474 GC patients from 3 tertiary centers in Germany, Lithuania and Latvia. Controls were patients from the out-patient departments, who were referred for upper endoscopy because of dyspepti...

In a recent paper, a GC-compositional strand bias, or GC-skew (=(C-G)/(C+G)) was reported, where C and G denote the numbers of cytosine and guanine residues, respectively, near the transcription start sites (TSS) in Arabidopsis [4]. However, it is unclear whether other eukaryotic species have similar GC-skews, and the biological meaning of that remains unknown. In this study, we conducted compa...

in order to compare planting season effect on agronomic of characters and yield of dill (anethum graveolens l.) an experiment based on completely randomized design with three replications was conducted in 2006-07 in esfahan province and three planting seasons (spring, summer and autumn) were evaluated. essential oil compositions were obtained by clevenger and recognized by gc-mass and gc. accor...

AIM To conduct a retrospective analysis regarding treatment strategies for early glottic cancer (GC) at ten institutions. PATIENTS AND METHODS A questionnaire-based survey was used to obtain personal and medical information on patients who started radiation therapy for T1 or T2 GC between January 2000 and December 2005. RESULTS A total of 279 patients were registered for the survey, of whom...

Two modified methods for assaying sodium diclofenac were developed by GC and HPLC. Diclofenac was converted into methyl ester derivative by methyl iodide in acetone. The ester was extract and subjected to GLC with flame ionization detector. %5 SE-30/chrom W-HP (80-100 mesh) was used as a column in GC. For reversed phase HPLC, the mobile phase was methanol and water (55-45). The separation was p...

Group specific component (Gc) is an abundant plasma protein whose functional role is not clearly established. Gc protein is synthesised in the liver and is known to bind vitamin D, vitamin D metabolites, and G actin; Gc protein is also implicated in macrophage activation. Several polymorphic electrophoretic variants of Gc protein are found in all human populations; the most common alleles are G...
