Approximately 60% of perioperative anaphylactic reactions are thought to be immunoglobulin IgE mediated, whereas 40% are thought to be non-IgE mediated hypersensitivity reactions (both considered non-dose-related type B adverse drug reactions). In both cases, symptoms are elicited by mast cell degranulation. Also, pharmacological reactions to drugs (type A, dose-related) may sometimes mimic sym...

Kinematic synthesis of a trailing six-member mechanism has been carried out to achieve five precision points of an automotive steering mechanism. The inner wheel can be rotated up to forty five degrees with fair accuracy. Results show that the divergent end behavior of Ackermann Steering Mechanism has been overcome by the present mechanism. The work is similar to earlier work by the present ...

the goal of this study was to assess attitude towards plagiarism in faculty members of medical school at tehran university of medical sciences. one hundred and twenty medical faculty members of tehran university of medical sciences were enrolled in this cross-sectional study. they were asked to answer to valid and reliable persian version of attitude towards plagiarism questionnaire. attitude t...

background: medical education has dramatically evolved in the past decades, and scholarly behaviors have gained popularity. in this study, scholarship-of-teaching activities from mashhad university of medical sciences (mums) were evaluated for the first time in this country. methods: data related to all applicants who were nominated for promotion to associate and full professor positions were s...

In this review, Saladino et al. present an intriguing hypothesis surrounding the role of formamide in the origins of life on Earth, backed by experimental results supporting each step from formamide to RNA polymers [1]. The overall premise is that, from formamide and inorganic phosphate, RNA molecules over 100 nucleotides in length can be produced. In addition, many carboxylic acids likely rele...

Covid-19 the disease takes its origin by November 2019 devastates life of many people globally, isolates everyone from employment, education, earning and family member droplet infection, end in emergency depleting one’s health.

Samples of dark to black fayalite from ten localities around the world were examined by 57Fe Mossbauer spectroscopy to see if any contained significant proportions of ferric iron. Of these ten samples, four, including a sample of ferrifayalite from Qianan County, China, previously known to contain ferric iron, were found to contain large amounts of this cation. Ferric/ferrous ratios of these sa...

Photocatalytic organic reactions were performed using automatic photocatalytic microreactor, where several open-end capillaries with photocatalytic materials coated inside were just soaked in a test tube including a reactant solution. Organic reactions of the alkyl radicals generated from carboxylic acids due to the photo-Kolbe reaction was studied, in analogy with the reactions using a photose...

asthma is a complicated disorder, whose prevalence has increased over the past few decades.asthma is characterized by infiltration of inflammatory leukocytes along with enhancedproinflammatory cytokines and chemokines. fungi are now far more widely being considered as thedominant extrinsic trigger for asthma. fungi are linked to the severity of asthma in many ways. somedifferences between studi...
