In this study, we have used density functional theory (DFT) calculations to characterize if and how defects influence the stability electronic/mechanical properties of M B 2 (AlB -type) for different transition metal . From a point defect analysis including vacancies, interstitials, anti-sites, identify vacancies be most favored, or least unfavored. To provide insight into possible vacancy orde...
A number of compounds have been found to prevent the diabetic action of alloxan when administered immediately before the al1oxan.l The writers have observed that the oxidation-reduction dye, methylene blue, not only is protective against the diabetogenic action of alloxan when given before the alloxan, but also exerts a marked blood sugarlowering effect when administered to rats previously made...
INTRODUCTION The mesiobuccal root of the maxillary first molar has generated more research and clinical investigation than any root. An inability to detect and treat a second mesiobuccal (MB2) canal is a reason for endodontic failure in maxillary first molars. Modifications in the endodontic access and detection techniques, along with advancements in illumination and magnification technology, h...
We measured total creatine kinase (CK), CK-MB isoenzyme, and the MB isoforms in 202 serum and plasma samples from nine groups of patients and normal individuals: 39 with acute myocardial infarction (MI), divided according to time between the onset of chest pain and blood collection (1-6 h, 7-12 h, and 13-48 h); 26 with chest pain for whom an MI was ruled out, sampled at admission; 17 undergoing...
Mycobacteria of the Mycobacterium tuberculosis complex (MTBC) greatly affect humans and animals worldwide. The life cycle of mycobacteria is complex and the mechanisms resulting in pathogen infection and survival in host cells are not fully understood. Recently, comparative genomics analyses have provided new insights into the evolution and adaptation of the MTBC to survive inside the host. How...
Background: A system based on the B-cell phenotype has recently been proposed to classify patients suffering from common variable immunodefi ciency (CVID). Immunophenotypic T-cell abnormalities have also been correlated with clinical fi ndings, although they have never been used in classifi cation strategies. Objective: To simultaneously assess T and B-cell subset abnormalities in CVID patients...
بیان مسأله: جهت برداشت پلاک میکروبی از سطوح دندانی، تاکنون روشهای مختلفی برای مسواکزدن ارائه شده است. توانایی این روشها در برداشت پلاک میکروبی و نیز زمان لازم برای آموزش، یادگیری و انجام آنها، میتواند متفاوت باشد؛ ضمن این که کارایی هر یک از این روشها ممکن است در طول زمان به دلیل کاهش دقت عمل کننده در رعایت اصول آموخته شده، کاهش یابد؛ به همین دلیل انتخاب مؤثرترین روش مسواکزدن مطلبی قابل بررسی...
2. "The majority of maxillary first molars had four root canals (59.5%), while only 40.5% had three root canals." 60% versus 40% is not such difference to use "only".We have corrected this sentence. The new sentence is as follows: “The majority of maxillary first molars had four root canals (59.5%), while 40.5% had three root canals.” 3. "There are differences in the number and configuration of...
The tail-flip escape behavior is a stereotypical motor pattern of decapod crustaceans in which swift adduction of the tail to the thorax causes the animal to rotate, move vertically into the water column and accelerate rapidly backwards. Previous predictions that a strong jet force is produced during the flip as the tail adducts to the body are not supported by our simultaneous measurements of ...
Denitrifying NO reductases are transmembrane protein complexes that are evolutionarily related to heme/copper terminal oxidases. They utilize a heme/nonheme diiron center to reduce two NO molecules to N2O. Engineering a nonheme Fe(B) site within the heme distal pocket of sperm whale myoglobin has offered well-defined diiron clusters for the investigation of the mechanism of NO reduction in thes...
