The aim of this study is to examine the protective effect of naringenin-oxime (NOX) on cisplatin-induced major organ toxicity and DNA damage in rats. Thirty-five male Wistar albino rats were equally split into five groups as follows: control (i.p., 0.1 ml of saline), Cis administration (i.p., 7 mg/kg b.w.), NOX treatment (i.p., 20 mg/kg b.w., daily for ten days), Cis + NOX20, and Cis + NOX40 co...

BACKGROUND Genetic and non-genetic factors probably act together to initiate and accelerate development of type 1 diabetes [T1D]. One suggested risk factor contributing to development of T1D is air pollution. OBJECTIVE The aim of the study was to investigate whether maternal exposure during pregnancy to air pollution, measured as nitrogen oxides [NOx] and ozone, in a low-dose exposure area wa...

Long-term administration of erythropoietin (EPO) frequently causes hypertension in humans and animals with chronic renal failure (CRF). We recently demonstrated that EPO-induced hypertension is hematocrit independent and accompanied by elevated cytosolic [Ca2+]i and nitric oxide (NO) resistance. This study was undertaken to examine the effects of therapy with EPO alone or together with calcium ...

Nitric oxide (NO)-related activity has been shown to be protective against Plasmodium falciparum in vitro. It has been hypothesized, however, that excess NO production contributes to the pathogenesis of cerebral malaria. The purpose of this study was to compare markers of NO production [urinary and plasma nitrate + nitrite (NOx)], leukocyte-inducible nitric oxide synthase type 2 (NOS2), and pla...

Reactive oxygen species are ubiquitous signaling molecules in biological systems. Four members of the NADPH oxidase (Nox) enzyme family are important sources of reactive oxygen species in the vasculature: Nox1, Nox2, Nox4, and Nox5. Signaling cascades triggered by stresses, hormones, vasoactive agents, and cytokines control the expression and activity of these enzymes and of their regulatory su...

Internet datacenters offer unprecedented computing power for a new generation of data-intensive computational tasks. There is a rapidly growing literature on the operating and distributed systems issues raised by these datacenters, but only recently have researchers turned their attention to the datacenter’s unique set of networking challenges. In contrast to enterprise networks, which usually ...

Recently, it has been shown that the degree of loading of several types of automotive exhaust aftertreatment devices can be directly monitored in situ and in a contactless way by a microwave-based method. The goal of this study was to clarify whether this method can also be applied to NOx storage and reduction catalysts (lean NOx traps) in order to obtain further knowledge about the reactions o...

The Environmental Protection Agency has recently proposed a reduction in mercury emissions from coal-fired power plants. There are two broad approaches under development to controlling mercury emissions from coal-fired electric utility boilers: (1) powdered activated carbon (PAC) injection, and (2) multipollutant control, in which Hg capture is enhanced in existing and new sulfur dioxide (SO2),...

ازن سطحی از اجزاء اصلی تشکیل اسماگ فتوشیمیایی در حضور اکسیدهای نیتروژن و ترکیبات آلی فرار به شمار می‌رود. این مطالعه با هدف تحلیل تغییرات غلظت ازن سطحی و ارتباط آن با تغییرات غلظت NOX در شهر تبریز با استفاده از داده‌های روزانه غلظت ازن و NOX در سه ایستگاه راه‌آهن، میدان نماز و آبرسان انجام شده است. بر اساس نتایج، تغییرات روزانه ازن و NOX تحت تأثیر شدید تغییرات فصلی و موقعیت ایستگاه بوده و در تم...
