Many patients with arthritis are using alternative modes of therapy, including nutritional supplements, to treat their arthritis. Most patients never tell their doctors that they are taking alternative medications, and few doctors even ask about such activities. Over-the-counter supplements are expensive and consume large amounts of patients' healthcare dollars. Glucosamine has been widely tout...

Patients receiving gentamicin or tobramycin were studied to determine whether there were differences in the urinary excretion of N-acetyl-beta-D-glucosaminidase (NAG) between the two groups. The average daily increases in NAG excretion were significantly higher in the group receiving gentamicin. In individual patients, the best correlation with nephrotoxicity was with high initial rates of NAG ...

INTRODUCTION Ischaemia-reperfusion injury (IRI) is a factor leading to the damages of the transplanted kidney, what affects mainly the proximal tubules. Early monitoring of tubule damage can be an efficient tool to predict the allograft dysfunction. Present in proximal tubules, N-acetyl-beta-glucosaminidase (NAG) is a lysosomal enzyme whose excretion rises as a result of IRI or acute rejection....

The present study aimed to determine the relationships between time of administration and dose of aminoglycosides, the extent of proximal tubule damage, evaluated by the urine N-acetyl-beta-D-glucosaminidase (NAG) activity, and to compare proximal tubule dysfunction in the patients treated with gentamicin and those receiving amikacin. The measurement of activity of NAG in urine was chosen to mo...

Gastric antral vascular ectasia (GAVE) and its nodular antral gastropathy (NAG) variant is a unique lesion associated with hypergastrinemic hormonal alterations that may be compounded by concurrent proton pump inhibitor (PPI) therapy. The use of octreotide as a somatostatin analogue and its role in the down regulation of variousenteric hormones has been well documented however its use in the ma...

Resumo Neste artigo, cujo objetivo é discutir condições de implementação um Modelo Praxeológico Alternativo – MPA, embasado em inter-relações entre domínios matemáticos, são apresentados aspectos epistemológicos-históricos três grandes matemáticos e algumas noções base da Antropologia Didática, para posterior apresentação características MPA. É feito recorte a saber: numérico-algébrico geométri...

niosomes are non-ionic surfactant vesicles that have potential applications in the delivery of hydrophilic and hydrophobic drugs. the topical form of n-acetyl glucosamine (nag) recently has been considered in the treatment of hyperpigmentation disorders due to its inhibitory effect on thyrosinase enzymes in melanocytes. to improve nag penetration into the skin we formulated the drug in niosomes...
