Calcium is an important factor in the ability of plants to resist salt stress, possibly because of its role in maintaining membrane integrity. We studied the effects of NaCl stress on membrane-associated Ca in corn root protoplasts (Zea mays L. cv Pioneer 3377) using the fluorescent Ca probe chlorotetracycline (CTC). Protoplasts were isolated from the cortex of primary roots of corn seedlings (...
The effect of disease-causing missense mutations on protein folding is difficult to evaluate. To understand this relationship, we developed the unfolding mutation screen (UMS) for in silico evaluation of the severity of genetic perturbations at the atomic level of protein structure. The program takes into account the protein-unfolding curve and generates propensities using calculated free energ...
Renal disease related to Waldenström macroglobulinaemia: incidence, pathology and clinical outcomes.
The incidence and prognostic impact of nephropathy related to Waldenström macroglobulinaemia (WM) is currently unknown. We performed a retrospective study to assess biopsy-confirmed WM-related nephropathy in a cohort of 1391 WM patients seen at a single academic institution. A total of 44 cases were identified, the estimated cumulative incidence was 5·1% at 15 years. There was a wide variation ...

the effect of learning strategies on the speaking ability of iranian students in the context of language institutes abstract language learning strategies are of the most important factors that help language learners to learn a foreign language and how they can deal with the four language skills specifically speaking skill effectively. acknowledging the great impact of learning strategies...
Abstract In the present study, optimization of microbiologically induced calcium carbonate precipitation (MICP) to produce biosandstone regarding compressive strength is shown. For production, quartz sand was treated sequentially with ureolytic microorganism Sporosarcina pasteurii (ATCC 11859) and a reagent containing urea chloride. Response surface methodology (RSM) applied investigate influen...
Abstract We inaugurate a program of “mass production” microlensing planets discovered in 2021 KMTNet data, with the aim laying basis for future statistical studies. While we ultimately plan to quickly publish all meeting some minimal criteria, current sample four was chosen simply on having low initial estimates planet–host mass ratio, q . It is therefore notable that two members this suffer fr...

BackgroundThe evidence for temperature control comatose survivors of cardiac arrest is inconclusive. Controversy exists as to whether the effects hypothermia differ per circumstances or patient characteristics.MethodsAn individual data meta-analysis Targeted Temperature Management at 33°C versus 36°C after Cardiac Arrest (TTM) and Hypothermia Normothermia Out-of-Hospital (TTM2) trials was condu...
previous studies have aimed at testing a hypothesis but the present study is data-first research in which researcher tries to form a theory from data rather than the use of data to test a hypothesis. this study aims at exploring teachers perceptions of the strengths and weaknesses of the current syllabus for college preparatory course. eight experienced teachers were selected to collect data du...
