Virus neutralization assays measure neutralizing antibodies in serum and plasma, the plaque reduction test (PRNT) is considered gold standard for measuring levels of these many viral diseases. We have developed procedures PRNT, microneutralization assay (MNA) pseudotyped virus (PNA) severe acute respiratory syndrome coronavirus 2. The MNA offers advantages over PRNT by reducing time, allowing i...

Background: Malnutrition, loss of body weight, muscle and fat mass wasting are common in patients with Parkinson's disease, and are associated with disability, longer length of hospital stay, impaired immune system and increased risk of mortality. The aim of this study was to assess the nutritional status in patients with Parkinson's disease and its relation to the severity of the disease. &...

Introduction: The Mini Nutritional Assessment (MNA) has been developed to assess malnutrition in elderly and to filter those who might get benefited from early diagnosis and treatment. The objective of the present study was to examine the nutritional profile of old age hospitalized individuals through the use of the MNA in King Khalid hospital at Hail city of Saudi Arabia. Methods: Demogra...

A novel triphenyltin(IV) derivative of 2-mercaptonicotinic acid (H(2)mna) of formula {[(C(6)H(5))(3)Sn](2)(mna).[(CH(3))(2)CO]} (1) has been synthesized and characterized by elemental analysis and (1)H, (13)C-NMR, and FT-IR spectroscopic techniques. The crystal structure of complex (1) has been determined by single crystal X-ray diffraction analysis at 173(1) K. Compound (1) contains two triphe...

N1-methylnicotinamide (MNA) is found in urine as an assymilation product when administered as nicotinic acid or nicotinamide. MNA was extracted from urine as a pure product and its physicochemical properties reported (4-6). Its maximum adsorption is reported by Hochberg, Melnick, and Oser (4) to lie at 265mƒÊ, E1cm1% 265mƒÊ=258 at pH 9.7. It is stable in urine in the dark for one week, even in ...
