In the present study, the effects of prenatal manganese (Mn) intoxication on the anxiolytic-like effects of diazepam and the 5-HT(1A) receptor agonist R-(+)-8-hydroxy-dipropylaminotetralin (8-OH-DPAT) were examined.Wistar dams were exposed to MnCl(2).4H(2)O at 5,000 ppm in the drinking water for the duration of pregnancy. On the day of parturition, Mn was discontinued as an additive in the drin...

The application of metaldehyde to agricultural catchment areas to control slugs and snails has caused severe problems for drinking water supply in recent years. In the River Thames catchment, metaldehyde has been detected at levels well above the EU and UK drinking water standards of 0.1 μg l-1 at many sites across the catchment between 2008 and 2015. Metaldehyde is applied in autumn and winter...

We have previously demonstrated that calcitonin gene-related peptide (CGRP) plays a counterregulatory role in subtotal nephrectomy-salt (SN-salt) hypertension through an increase in vascular responsiveness to the dilator activity of this neuropeptide. Substance P (SP) is often co-localized with CGRP in perivascular sensory nerves. To determine the role and mechanism of action of SP in SN-salt h...

SKADHAWCE, E., AND S. Il. BRADSHAW. Saline drinking and cloacal excretion of salt and zvater in the zebra finch. Am. J. Physiol. 227(6) : 1263-1267. 1974.-Zebra finches (‘Ihenio@ygia castanotis) from Western Australia were studied in order to investigate whether wild-caught animals were able to concentrate their urine to a higher degree than domesticated birds and whether they could drink fluid...

BACKGROUND To design the most appropriate interventions to improve water quality and supply, information is needed to assess water contamination in a variety of community settings, including those that rely primarily on unimproved surface sources of drinking water. OBJECTIVES We explored the role of initial source water conditions as well as household factors in determining household water qu...

during the past two centuries, production and consumption of nitrate, especially in agricultural field, have been increased considerably. currently many countries in the world including iran encounter to a high nitrate level in drinking water. the main reason is the seepage of agricultural runoff and municipal and industrial wastewater to water resources, particularly groundwater. from the old ...

background: cement production is associated with heavy metal emissions and environmental pollution by cement dust. the degree of contamination of drinking water sources by major and trace elements present in cement dust generated by united cement factory (unicem) is still uncertain. this study estimated the element content of ground and surface water samples (hand-dug wells, boreholes and strea...

introduction: giardia and cryptosporidium are two of the most common parasitic protozoa that cause acute intestinal infections in children, all of the world. these parsites find in water environments, such as untreated water , wastewaters and even treated water. according to, a precise study on surface water was not done, in our country, necessity of precise study by ifa method that is prescise...

An experiment was conducted to assess the impact of increasing levels of supplemental soybean meal (SBM; 45.7% CP) in cattle consuming tropical grass hay (Panicum maximum cultivar Gatton; 7.0% CP and 81.8% NDF) and drinking low salt water (LS) or high salt water (HS). Six ruminally fistulated beef steers (BW = 375 ± 43 kg) were used in a 6-treatment, 4-period crossover experiment. Treatments we...
