When renin is administered intramuscularly to the rat, massive proteinuria occurs without a significant elevation of mean arterial blood pressure. The intravenous administration of renin to normal rats results in a great increase in urinary protein excretion. This response to renin is abolished by bilateral adrenalectomy. While the adrenalectomized rat fails to respond to intravenous renin with...

BACKGROUND AND AIMS The determination of the prevalence of cardiopulmonary complications at a liver transplant center in Iran. METHODS Ninety-nine patients (61 male and 38 female) with a mean age of 36.5 (15-66) years with proven cirrhosis were enrolled in this study. Patients with primary cardiac disease, current smokers, those with sepsis, hepatocellular carcinoma, recently ruptured esophag...

The control of tissue growth, which is a key to maintain the protective barrier function of the epithelium, depends on the balance between cell division and cell extrusion rates [1, 2]. Cells within confluent epithelial layers undergo cell extrusion, which relies on cell-cell interactions [3] and actomyosin contractility [4, 5]. Although it has been reported that cell extrusion is also dependen...

The link between the digestive tract and atopic dermatitis has been studied for many years, and new ground has been broken thanks to studies on the intestinal flora made possible with bacterial metagenomic techniques. Through the detailed analysis of the fecal microbiome of atopic and non atopic subjects, Korean researchers have found no major difference in the diversity patterns of the species...

Color light therapy is a therapeutic method in complementary medicine. In color therapy, light of two contrasting colors is often applied in a sequential order. The aim of this study was to investigate possible physiological effects, i.e., changes in the blood volume and oxygenation in the brain and calf muscle of healthy subjects who were exposed to red and blue light in sequential order. The ...

Alcohol has been shown to interact with lead to influence haem biosynthesis. The aim of this study was to define the dependence of this interaction on the degree of exposure to lead. Exposure to alcohol was estimated by measurement of alcohol concentrations in a sample of urine collected during the morning (AlcUM) (0.82 (SD 4.36) mmol/l) and in a sample collected during the afternoon (AlcUA) (1...

Mammalian oocytes can undergo artificial parthenogenesis in vitro and develop to the blastocyst stage. In this study, using real-time PCR, we analyzed the expression of genes representative of essential events in development. In vitro matured oocytes were either fertilized or activated with ionomycin + 6-DMAP and cultured in simple medium. The pluripotency-related gene Oct3/4 was downregulated ...

We retrospectively reviewed 419 HIV/AIDS patients in Hospital Kuala Lumpur from 1994 to 2001. In the male group, the age range was 20-74, with a mean age 37 years, while in the female group it was 17-63, with a mean age of 33 years. With regard to age group, it was found that the preponderant age group was 25-34 years. The majority of male subjects were Chinese (52.5%), single (56.3%), and unem...

Allopolyploidy has played a prominent role in organismal evolution, particularly in angiosperms. Allohexaploidization is a critical step leading to the formation of common wheat as a new species, Triticum aestivum, as well as for bestowing its remarkable adaptability. A recent study documented that the initial stages of wheat allohexaploidization was associated with rampant genetic and epigenet...

A review of the very full literature upon the concentration of ammonia in blood discloses much confusion and divergence in the reported values. For example, the range of values for the systemic blood of normal dogs is from a few hundredths of a mg. (Folin and Denis, 1) to 5 mg. (MacCallum and Voegtlin, 2) or more of ammonia nitrogen in 100 cc. Even more pronounced are variations in the data of ...
