Quantitative analysis of phospholipids by 31P-NMR.
High-field 31P nuclear magnetic resonance spectroscopy was used to quantitate phospholipids in mixtures in organic solvents. The sample is dissolved in chloroform-methanol and analyzed at 161.7 MHz with decoupling of the protons. Signals were identified using authentic compounds, and their relative distribution was measured in mole percent. The method has good accuracy and reproducibility, and ...
متن کاملThe lymphocytic cholinergic system and its modulation by organophosphorus pesticides.
Clinical and basic mechanism observations reveal interactions between neural and immune systems. These two systems create a complex network for recognizing danger to the host and its protection from outside pathogenic elements as well as from inside overreactions of inflammatory character. Here, we review the interactions of these two systems in relation to the effects of pesticides that clearl...
متن کاملOrganophosphorus Pesticides - Mechanisms Of Their Toxicity
In this rapidly developing, capitalist world, people are continually exposed to numerous environmental pollutants such as industrial waste, polluted air and pesticides. These invariably comprise complex mixtures of chemicals. The effects of the mixtures and their mode of action in humans are insufficiently well studied. The majority of pollutants are potentially toxic for organisms, some being ...

در این پایان نامه نشان داده ایم که چگونه می توان مدل ریسک بیمه ای اسپیرر اندرسون را به کمک زنجیره های مارکوف تعریف کرد. سپس به کمک روش های آنالیز ماتریسی احتمال برشکستگی ، میزان مازاد در هنگام برشکستگی و میزان کسری بودجه در زمان وقوع برشکستگی را محاسبه کرده ایم. هدف ما در این پایان نامه بسیار محاسباتی و کاربردی تر از روش های است که در گذشته برای محاسبه این احتمال ارائه شده است. در ابتدا ما نشا...
15 صفحه اولMultidimensional profiling platforms reveal metabolic dysregulation caused by organophosphorus pesticides.
We are environmentally exposed to countless synthetic chemicals on a daily basis, with an increasing number of these chemical exposures linked to adverse health effects. However, our understanding of the (patho)physiological effects of these chemicals remains poorly understood, due in part to a general lack of effort to systematically and comprehensively identify the direct interactions of envi...
