Frequency, duration, and intensity of hot-weather events are all predicted to increase with climate warming. Despite this, mechanisms by which temperature increases affect individual fitness and drive population-level changes are poorly understood. We investigated the link between daily maximum air temperature (tmax) and breeding success of Kalahari common fiscals (Lanius collaris) in terms of ...

Recombinant high density lipoprotein (rHDL) particles were prepared by cosonication of purified lipids and human apoproteins and incubated with partly purified cholesteryl ester transfer protein (CETP) and low density lipoprotein (LDL) containing [3H]cholesteryl ester. Increasing the triglyceride content relative to cholesteryl ester in rHDL significantly decreased the ability of the particles ...

BACKGROUND AND PURPOSE Acute stroke patients with unknown time of symptom onset are ineligible for thrombolysis. The diffusion-weighted imaging and fluid-attenuated inversion recovery (FLAIR) mismatch is a reasonable predictor of stroke within 4.5 hours of symptom onset, and its clinical usefulness in selecting patients for thrombolysis is currently being investigated. The accuracy of the visua...

The primary objective of the paper was to characterize climatic conditions in winter season Poland years 1966/67–2019/20. study based on daily values minimum (Tmin) and maximum air temperature (Tmax), snow cover depth. showed an increase both Tmin Tmax winter. most intensive changes were recorded north-eastern northern regions. coldest winters first half analyzed multiannual period, exceptional...

ion reactions reach their maximum rates, however, in the high-temperature region, where thermal decomposition reactions are also most active. Formation and Consumption of Other Olefins. Despite the model-dependent differences in reactions of heptene isomers, the chemistry of other olefins is very similar for all three mechanisms, especially for larger olefins. Reactions that involve oxygenated ...

PURPOSE To investigate if delays in resting-state spontaneous fluctuations of the BOLD (sfBOLD) signal can be used to create maps similar to time-to-maximum of the residue function (Tmax) in Moyamoya patients and to determine whether sfBOLD delays affect the results of brain connectivity mapping. MATERIALS AND METHODS Ten patients were scanned at 3 Tesla using a gradient-echo echo planar imag...

To determine whether left ventricular (LV) end systole and end ejection uncouple in patients with long-term mitral regurgitation, 59 patients (22 control patients with atypical chest pain, 21 patients with aortic regurgitation, and 16 patients with mitral regurgitation) were studied with micromanometer LV catheters and radionuclide angiograms. End systole was defined as the time of occurrence (...

PURPOSE The aim of this study was to evaluate the changes in salivary gland function in patients with chronic renal failure (CRF) undergoing hemodialysis. METHODS The group consisted of 23 patients with CRF (13 female, 10 male; mean age: 40 +/- 13 yr) and 14 healthy control subjects (mean age: 40 +/- 13 yr). All underwent dynamic salivary gland scintigraphy with gustatory stimulation. After i...

The significance of hepatobiliary scintigraphy (HBS) for hepatic graft function assessment was established mostly on retrospective studies and was not widely recognized due to the lack of quantitative data and variation in accuracy. This prospective study was performed to investigate the effectiveness of quantitative HBS for assessing hepatocyte dysfunction and biliary complication in liver tra...

Abstract Using the daily 2 m maximum temperature (Tmax), minimum (Tmin) and cloud cover data measured at ground sites of China Meteorological Administration in North from 2000 to 2017, this study investigates influence clouds on range (DTR) defined as difference between Tmax Tmin. As expected, shows similar averaged spatial distribution monthly variation with Surprisingly, it also average Tmax,...
