The aim of this study was to optimize the preparation method polymethyl methacrylate (PMMA) denture base loaded with nano silver (NAg), more effectively and safely impart sustainable antibacterial functions. NAg solution synthetized mixed acrylic acid methyl methyacrylate (MMA) monomer in order prepare a new type (NS)/polymer specimens (NS/PMMA). surface morphology, mechanical strength, antimic...

Epithelial ovarian cancer (EOC) remains the most lethal gynecologic malignancy in developed countries. Chronic endogenous sterile pro-inflammatory responses are strongly linked to EOC progression and chemoresistance to anti-cancer therapeutics. In the present study, the activity of epithelial NF-κB, a key pro-inflammatory transcription factor, was enhanced with the progress of EOC. This result ...

n-acetyl-b-d-glucosaminidase was purified by affinity and ionexchange chromatography. two major, a and b, and three minor intermediate forms were isolated and characterized. nag-a and nag-b were purified 440 and 1200 fold with final yields of 16 and 23 percent respectively. each activity was represented by a single protein band. after 70 min preincubation at 55°c a loss of70% activity of nag-a ...

The beta-hexosaminidase inhibitor and structural analog of the putative oxazolium reaction intermediate of lytic transglycosylases, N-acetylglucosamine thiazoline (NAG-thiazoline), was synthesized in 46% overall yield and tested as an inhibitor of Escherichia coli growth. NAG-thiazoline, at concentrations up to 1 mg/ml, was not found to affect the viability of E. coli DH5alpha. However, the com...

Serum aminoglutethimide (AG) and N-acetylaminoglutethimide (NAG) concentrations were measured by high pressure liquid chromatography (HPLC) in 24 postmenopausal women with advanced breast cancer receiving increasing doses of oral AG. Patients received 62.5mg b.d., 125mg b.d., 250mg b.d., and 500mg b.d. of AG alone, and 500mg b.d. of AG combined with hydrocortisone (HC) 20mg b.d. Dose was increa...

OBJECTIVES To assess urinary NAG/ urinary creatinine (NAG/ Cr) ratio in patients with urological abnormalities (normal and abnormal ultrasonography) and compare it with normal healthy children. METHODS A prospective study was conducted from November 2012 to April 2013. Urine samples were collected from 70 patients with various urological abnormalities, and from 40 healthy control groups, thei...

In Ralstonia sp. strain U2, the nag catabolic genes, which encode the enzymes for the pathway that catabolizes naphthalene via the alternative ring cleavage gentisate pathway, are transcribed as an operon under the same promoter. nagR, which encodes a LysR-type transcriptional regulator, is divergently transcribed compared to the nag catabolic genes. A 4-bp frameshift deletion in nagR demonstra...

BACKGROUND Renal failure is one of the most serious complications associated with autosomal dominant polycystic kidney disease (ADPKD). To date, early markers have failed to predict renal function deterioration at the early stages. This 1-year prospective study evaluated N-acetyl-β-D-glucosaminidase (NAG) as a new surrogate marker for renal function in ADPKD. METHODS A total of 270 patients w...

INTRODUCTION There are new concepts and developments in the diagnosis and management of acute pancreatitis. Current evidence suggests that there is no role of prophylactic antibiotics use in acute pancreatitis. However, it is still a common practice to administer prophylactic antibiotics in a country like Nepal. So, we have conducted a study in mild and moderately severe acute pancreatitis to s...
