The seeds of Cucurbita maxima contain protein bodies with electrondense globoid crystals. Because of their density globoid crystals are ideal material for energy-dispersive x-ray (EDX) analysis studies of elemental composition. Fixation trials were carried out to test globoid crystal extraction during glutaraldehyde fixation, water washing, and ethanol dehydration. Glutaraldehyde fixation witho...

Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) USA300 has spread rapidly across North America, and CA-MRSA is also increasing in Australia. However, the dominant Australian CA-MRSA strain, ST93-IV [2B] appears distantly related to USA300 despite strikingly similar clinical and epidemiological profiles. Here, we compared the virulence of a recent Australian ST93 isola...

Background: In recent years, Tehran has faced major problems with air pollution for many reasons, and this issue has become a critical point in most of the days. However, less attention has been paid to the indoor air pollutants in exercise centers and their possible health effects. In this research, it was tried to briefly describe the characteristics and chemical composition of the aerosols p...

in the paper, the contents of calcium (ca), magnesium (mg), zinc (zn), copper (cu), iron (fe),manganese (mn), chromium (cr), lead (pb), cadmium (cd), aluminium (al), and nickel (ni) were determinedin the meat of roe deers, wild boars, and hares coming from central region of poland. measurements werecarried out using atomic absorption spectrometry. the ranges of median values found for the conce...

Background: Oral lichen planus (OLP) is a common inflammatory disease of unknown origins. Recent studies have considered nutritional factors concerning the pathogenesis of many autoimmune disorders. The objective of the present study was to investigate the plasma levels of magnesium (Mg), calcium (Ca), zinc (Zn), copper (Cu), and iron (Fe) in this disorder. Methods: Included in this observation...

THIS MONOLOG is part of an APS series on major findings that have shaped many of our present concepts regarding what we currently understand as physiology. The process of Ca-induced Ca release was a topic of much discussion and debate when first introduced. The seminal manuscript on this topic is often considered that of Alexandre Fabiato, “Calcium-induced release of calcium from the cardiac sa...

Virus capsid assembly constitutes an attractive target for the development of antiviral therapies; a few experimental inhibitors of this process for HIV-1 and other viruses have been identified by screening compounds or by selection from chemical libraries. As a different, novel approach we have undertaken the rational design of peptides that could act as competitive assembly inhibitors by mimi...

The hydrogeochemical properties of bottled waters (n = 37) were examined to evaluate the factors governing their quality and suggest natural background levels (NBLs) groundwater. sourced from bedrock aquifers various geological types analyzed for 14 physicochemical parameters 48 trace elements. mainly consisted Ca-HCO3 type with low TDS (mean 158.4 mg/L; n 33) regardless type, indicating degree...
