Ingestion of sodium is essential to health, but excess sodium intake is a risk factor for hypertension and cardiovascular disease. Defining an optimal range of sodium intake in populations has been challenging and controversial. Clinical trials evaluating the effect of sodium reduction on blood pressure have shown blood pressure lowering effects down to sodium intake of less than 1.5 g/day. Findings from these blood pressure trials form the basis for current guideline recommendations to reduce sodium intake to less than 2...

Skeletal muscle function has been scarcely investigated in sickle cell disease (SCD) so that the corresponding impact of sickle hemoglobin is still a matter of debate. The purpose of this study was to investigate muscle force production and fatigability in SCD and to identify whether exercise intensity could have a modulatory effect. Ten homozygous sickle cell (HbSS), ten control (HbAA) and ten heterozygous (HbAS) mice were submitted to two stimulation protocols (moderate and intense) to assess force production and fatigability...

Both sleep loss and pathogens can enhance brain inflammation, sleep, and sleep intensity as indicated by electroencephalogram delta (δ) power. The pro-inflammatory cytokine interleukin-1 beta (IL-1β) is increased in the cortex after sleep deprivation (SD) and in response to the Gram-negative bacterial cell-wall component lipopolysaccharide (LPS), although the exact mechanisms governing these effects are unknown. The nucleotide-binding domain and leucine-rich repeat protein-3 (NLRP3) inflammasome protein complex forms in response to changes in the local environment and, in turn, activates caspase-1 to convert IL-1β into its active form...

There is evidence that Thai patients receiving standard doses of ritonavir (RTV)-boosted atazanavir (ATV/r) have high exposure to atazanavir (ATV) leading to a higher risk of toxicity. A lower dose of ATV/r may provide adequate exposure in this population. However, pharmacokinetic data on ATV/r in Thai patients required for dose adjustment are limited. This study aimed to develop a population pharmacokinetic model of ATV/r and to determine the influence of patient characteristics on ATV pharmacokinetics. Monte Carlo simulations were performed to estimate the proportion of patients achieving target ATV trough concentration (Ctrough) with the standard ATV/r dose of 300/100 mg and a low dose of 200/100 mg once daily (OD)...

A key goal for livestock science is to ensure that food production meets the needs of an increasing global population. Climate change may heighten this challenge through increases in mean temperatures and in the intensity, duration, and spatial distribution of extreme weather events, such as heat waves. Under high ambient temperatures, livestock are expected to decrease dry matter intake (DMI) to reduce their metabolic heat production. High yielding dairy cows require high DMI to support their levels of milk production, but this may increase susceptibility to heat stress...

INTRODUCTION: The 9/11 terrorist attacks on the World Trade Center resulted in elevated post-traumatic stress disorder (PTSD) and alcohol use among exposed individuals. The relationship among traumatic exposure, PTSD, and excessive drinking is well documented; however, little is known about these relationships in the long term. This study examines factors increasing binge drinking risk among exposed individuals a decade post-9/11. METHODS: In 2015-2016, data were analyzed from 28,592 World Trade Center Health Registry enrollees aged ≥18 years who completed the Wave 3 (2011-2012) survey...

A novel mitochondria targeting fluorescent probe compound S-N3 as the monitor of Hydrogen Sulfide (H2 S) in living cells has been designed and synthesized in this paper. This article contained the chemosynthesis and some studies on bioactivity of the target compound in living cells. Compound S-N3 is easy to synthesize and can remain stable under the effect of pH, system and photo. In additional, it shows low cytotoxicity in cell imaging. And it can react with H2 S highly selective in PBS or FBS solution, which would cause the obvious increase of fluorescence intensity...

Glioblastoma is a lethal disease featured with a high proliferation of tumor cells, excessive angiogenesis, and heavydrug resistance. The overall survival of glioblastoma patients was dismal even with intensive standard care. Recent advantages in immune checkpoint blockades are changing the treatment of cancers. However, the efficacy of immune checkpoint blockades in glioblastoma were unclear. Here, we investigated the roles of CD103<sup>+</sup> cells in regulating the effects of immune checkpoint blockades in glioblastoma mouse models...

We investigated the response to increasing intensity of red (R) and far-red (FR) light and to a decrease in R:FR ratio in Pinus sylvestris L. (Scots pine) seedling. The results showed that FR-high irradiance response (FR-HIR) for hypocotyl elongation may be present in Scots pine, and that this response is enhanced by increasing light intensity. However, both hypocotyl inhibition and pigment accumulation were more strongly affected by the R light compared to FR light. This is in contrast to previous reports in Arabidopsis thaliana (L...

Soil compaction causes substantial reduction in agriculture productivity and has always been of great distress for farmers. Intensive agriculture seems to be more crucial in causing compaction. High mechanical load, less crop diversification, intensive grazing, and irrigation methods lead to soil compaction. It is further exasperated when these factors are accompanied with low organic matter, animal trampling, engine vibrations, and tillage at high moisture contents. Soil compaction increases soil bulk density and soil strength, while decreases porosity, aggregate stability index, soil hydraulic conductivity, and nutrient availability, thus reduces soil health...

Mining activities are responsible for high concentrations of metals in river networks in many parts of the world. Mining activities and the resulting high loads of heavy metals interact with intensive acid rain, and often have great consequences for biodiversity. However, considering the frequently episodic nature of these heavy acid rains, there is little detailed evidence of direct impacts. In 2011 we observed a massive mortality of noble crayfish and stone crayfish in Padrťsko Special Area of Conservation (SAC) in the Brdy Mountain region of the Czech Republic...

Lampreys and hagfishes are the sole extant representatives of the early agnathan (jawless) vertebrates. We compared retinal function of fully-metamorphosed, immature Mordacia mordax (which are about to commence parasitic feeding) with those of sexually-mature individuals of its non-parasitic derivative M praecox We focused on elucidating the retinal adaptations to dim-light environments in these nocturnally-active lampreys, using electroretinography to determine the temporal resolution (flicker fusion frequency, FFF) and temporal contrast sensitivity (CS) of enucleated eyecups at different temperatures and light intensities...
