BACKGROUND We established a rat model of chronic mountain sickness using acetyl-L-cysteine. Then we studied the effects and mechanisms of acetyl-L-cysteine (Da) in rats with chronic mountain sickness using nuclear magnetic resonance (H1-NMR) metabolomics methods. MATERIAL AND METHODS Using NMR spectroscopy combined with pattern recognition and orthogonal partial least squares discriminant ana...

b a ckground: a two year seroepidemiological study was designed to find out the seroprevalence and risk factors ofcanine visceral leishmaniasis (cvl) among stray and owned dogs in tehran and alborz provinces of iran. me t hods: blood samples of  602 dogs living in  11  counties of  tehran and  alborz  provinces were  taken by venipuncture in 2008–2010. after separation of blood sera, anti-leish...

Introduction: Polyorchidism is a rare medical condition, which is presence of more than two testes within the scrotum. Triorchidism is the more common form and the diagnosis is made with ultrasonography. One of the common anomalies associated with polyorchidism is testicular torsion. Case Report: We report a case with four testes and testicular torsion in one testis. Conclusion: Testicular tors...

The general aim of this study, which was conducted for the first time in Iran, was to evaluate the seroprevalence and geographical distribution of Ehrlichia canis in a dog population in Iran, followed by molecular confirmation using PCR and sequencing. Blood samples were collected from 240 dogs in different areas of Alborz and Tehran Provinces and initially analyzed using the immunofluorescent ...

In India, Kerala state is known to have relatively high lightning incidence. The nature of spatial and temporal distribution of past incidents, type of thunderclouds which cause lightning, the topography, proximity to a mountain range and sea point to the possibility of the mountain weather aiding in Cb formation. For investigating the role of mountain weather in convective Cb formation a field...

1. introduction the effect of climate of the earth's surface is the result of interaction of different levels of atmosphere and lithosphere. one of the factors which influences that interaction is the way the system pressure transcends it. in this way, the system pressure changes and can be changed and eventually may become an environmental hazard and geomorphodynamic phenomenon. hazards are an...

In this paper, we study a kind of anisotropic p-Laplacian equations in R n. Nontrivial solutions are obtained using mountain pass theorem given by Ambrosetti-Rabinowitz [1].

The classic Coupon-Collector Problem (CCP) is generalized. Only basic probability theory is used. Centerpiece rather is an algorithm that efficiently counts all k-element transversals of a set system.
