Photodynamic therapy (PDT) efficacy in cancer cells is affected by sub-physiological hypoxia caused dysregulated and chaotic tumor microvasculature. However, current traditional O2-replenishing strategies are undergoing their own intrinsic deficiencies. In addition, resistance mechanisms activated during PDT also lead the present situation far from satisfactory. Methods: We propose a nitric oxi...
BACKGROUND & OBJECTIVES The Arg>Pro polymorphism in codon 72 of p53 gene is known to affect the susceptibility of cervical cancer differently in different population worldwide although information regarding its role in determining survival status and disease outcome in patients is lacking. The present study was conducted to determine the genotype frequency and prognostic role of p53 codon 72 Ar...
هدف: تحقیق حاضر با هدف مقایسه تأثیر یک هفته مکملسازی سیترولین-مالات (Cit) و ال-آرژنین (Arg) بر مقادیر هورمون رشد و پاسخهای متابولیکی مردان کشتیگیر متعاقب آزمون شبیه ساز کشتی انجام شد. روش: در یک مطالعه نیمهتجربی، 20 کشتیگیر 25-19 ساله (وزن، 90-60 کیلوگرم و درصد چربی 20-12 درصد) انتخاب و به صورت تصادفی و دوسویهکور در دو گروه همگن مکملسازی یک هفتهای Arg (چهارگرم در روز) و Cit (چهارگرم در ...
Carbon nanotubes (CNTs) have very promising applications for inhibition of microbial growth. The aim of this study is investigation and comparison of the effect of temperature and acidity on antimicrobial activities of pristine Multiwalled Carbon nanotubes (MWCNTs) and Multiwalled Carbon nanotubes-Arginine (MWCNTs-Arg). Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Conc...
Purpose: We studied of quality and quantity differentation of mouse uterus after the injection of L-Name, L-Arg and normal saline on the 3rd, 4th and 5th days of pregnancy. Materials and Methods: Twenty mice that were 8 weeks old and 200-250g were kept in animal house conditions for one week. By looking at the vaginal plaque, we devided the pregnant mice into 4 groups of 5, consisting of: 1/co...
An argument is a reason or justification of a claim. It has an intrinsic strength and may be attacked by other arguments. Hence, the evaluation of its overall strength is mandatory. Such an evaluation is done by acceptability semantics. In this talk, we provide the foundations of a semantics, i.e., key concepts and principles on which an evaluation is based. Each concept (principle) is describe...
Arginine (Arg) is a conditionally-essential amino acid that is taken up by bovine mammary gland in excess of its output in milk. In this study we evaluated the effects of Arg concentration on the expression of casein and signaling pathway-related genes in mammary epithelial cells. The treatments (applied for 24 h) were designed to be devoid of Arg 0X (control; 0.00 mg/L), resemble the profile o...
A functional urea cycle with both cytosolic (ARG I) and mitochondrial (ARG II) arginase activity is present in the liver of an ureogenic air-breathing teleost, Heteropneustes fossilis. Antibodies against mammalian ARG II showed no cross-reactivity with the H. fossilis ARG II. ARG II was purified to homogeneity from H. fossilis liver. Purified ARG II showed a native molecular mass of 96 kDa. SDS...
L-arginine and arginine analogues: effects on isolated blood vessels and cultured endothelial cells.
1. The present study examined effects of arginine (Arg) and various Arg analogues on the vascular tone of rabbit and rat aortic rings, the release of nitrite from cultured bovine aortic endothelial cells and the metabolism of L-Arg in bovine and porcine endothelial cell homogenates. The respective D-enantiomers or N-alpha-benzoyl-L-arginine ethyl ester did not substitute for L-Arg. 2. In bovine...
Although there have been several studies investigating a possible association between essential hypertension and TSC gene Arg904Gln polymorphisms, the results have been inconsistent. We conducted a meta-analysis of four case-control studies (one study in Europe and three studies in Asia), including 1811 essential hypertension cases and 1381 controls. The pooled results showed no significa...
