two omega-3 fatty acids including docosahexaenoic acid (dha) and eicosapentaenoic acid (epa) are essential for the physiologic function of neuronal cell membrane. normal function of neuronal cell membrane requires appropriate composition of fatty in its structure. present study was designed to compare the effect of short-term and long-term pretreatment with omega-3 fatty acids on scopolamine-in...

BACKGROUND Many studies have reported significant associations between exposure to PM(2.5) and hospital admissions, but all have focused on the effects of short-term exposure. In addition all these studies have relied on a limited number of PM(2.5) monitors in their study regions, which introduces exposure error, and excludes rural and suburban populations from locations in which monitors are n...

We use a unique dataset of German banks’ exposure to interest rate risk to derive the following statements about their exposure to this risk and their earnings from term transformation. The systematic factor for the exposure to interest rate risk moves in sync with the shape of the term structure. At bank level, however, the time variation of the exposure is largely determined by idiosyncratic ...

A cyclic plastic zone area near fatigue-fractured surface was studied using a back-reflection camera and high intensity, microbeam, synchrotron X-ray source (SR) in order to measure the variation of the stress intensity factor range (AK) along the fatigue fracture. The existence of subgrains within the cyclic plastic region was shown by the appearance of small spots in the Debye-Scgerrer rings ...

SINCE 1958, the Atomic Bomb Casualty Commission (ABCC) has been conducting a long-term follow-up investigation (Adult Health Study) [ 1] of large defined population samples in Hiroshima and Nagasaki, Japan. In the course of this program the prevalence of definite rheumatoid arthritis was measured and its incidence estimated, according to observations made upon 16,269 subjects from 1958 to 1964 ...

Background: Liver is an important organ that responsible for biological detoxification. There are few studies about the effect of co-exposure to organic solvents and noise on hepatic system enzymes. The study aim was to assess the effects of short-term exposure to noise and styrene on rat liver enzymes. Materials and Methods: In this experimental study, we studied the liver enzymes of male r...

health care workers (hcw) are at high risk of occupational exposure from blood-borne pathogens. the most important pathogens that can be transmitted to hcw are hiv with prevalence of 2.24 per 100000, hbv with prevalence of 2.3%, and hcv with prevalence of 0.2% in iran. most of this occupational transmission can be prevented through standard precautions reducing exposure. these precautions, howe...

OBJECTIVES The level of benzene exposure in the petrochemical industry during regular operation has been well established, but not in turnaround (TA), where high exposure may occur. In this study, the characteristics of occupational exposure to benzene during TA in the petrochemical companies were investigated in order to determine the best management strategies and improve the working environm...

Conventionally, measurements of carbon isotopes in atmospheric CO2 (δ CO2) have been used to partition fluxes between terrestrial and ocean carbon pools. However, novel analytical approaches combined with an increase in the spatial extent and frequency of δCO2 measurements allow us to conduct a global analysis of δCO2 variability to infer the isotopic composition of source CO2 to the atmosphere...

Introduction: The effects of cannabinoids (CBs) on synaptic plasticity of hippocampal dentate gyrus neurons have been shown in numerous studies. However, the effect of repeated exposure to cannabinoids on hippocampal function is not fully understood. In this study, using field potential recording, we investigated the effect of repeated administration of the nonselective CB receptor agonist WIN5...
