Inhibition of oxidative stress and advanced glycation end-product formation in purified BSA/glucose glycation system by polyphenol extracts of selected nuts from Pakistan.

Glycation generates advanced glycation end products (AGE) and its intermediates, thus increasing the risk of developing various ailments including diabetes mellitus. Current study was planned to explore the antioxidant and antiglycation potential of selected nuts viz, Juglans regia (Walnut), Prunus dulcis (Almond), Pistacia vera (Pistachio), and Arachis hypogaea (Peanut), locally available and readily consumed in Faisalabad, Pakistan, for their health-promoting properties. The prepared methanolic extracts of selected nuts were tested for biological activities including the antioxidant and antiglycation potential. The effect of these extracts against oxidation and AGE formation was evaluated by in vitro method using bovine serum albumin (BSA)-glucose system. Juglans regia, Pistacia vera, and Arachis hypogaea were found rich in phenolics and flavonoids contents with increased reducing potential and least IC50 due to the DPPH free radical scavenging inhibition. Dose- and time-dependent inhibition of glucose-induced advanced glycation end-product (AGE) was exhibited by fruit extracts through in vitro bovine serum albumin (BSA)-glucose system. Juglans regia and Pistacia vera were predominantly effective in the inhibition of early and intermediary glycation products at different incubation conditions. The study indicated that the extracts of selected nuts possess significant antioxidant capacity and are rich in phenolics and flavonoids, making them useful supplements as an important part of a balanced diet.

Disease specific symptoms indices in patients with celiac disease-A hardly recognised entity.

Background: Celiac disease (CD) was considered a rare disease before and was perceivably only limited to children but now affects almost 1-2% of the global population. This abrupt increase in prevalence is due to advancements in diagnostic criteria and medical facilities but still many countries lack the basic data that can assess the severity of this health issue. The present study was conducted with the aim to assess the common but rarely diagnosed condition with the identification of its underlying secondary ailments. Materials and methods: Patients visiting public sector hospitals were recruited and tested for clinical symptoms secondary to gluten-containing foods (wheat and barley, etc.), followed by serological testing for immunoglobulin A, tissue transglutaminase A, and anti-endomysial antibodies. Only seropositive candidates were included in the endoscopic and biopsy examination for the features of villous atrophy and intestinal cell damage. The secondary ailments including anemia, growth retardation, and gastrointestinal symptoms were also documented for the tested positive patients. The modified European Society of Pediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) criterion was followed throughout the study. Results: From 647 suspected cases from March 2018 to July 2019, 113 were confirmed with CD while 58% were female children and 42% were male children. The majority of them were from a lower class (75%) and 26% of them had a positive family history of CD. A total of 67% of patients with CD were underweight while wasting was observed in 38%, and 80% were stunted as well. Of the positively tested patients with CD, 49% had moderate anemia with 15% having severe anemia. Approximately 33% had hypoalbuminemia as well. The majority of them had a mild to severe range of gastrointestinal symptoms, such as abdominal pain, diarrhea, flatus, eructation, diarrhea, and steatorrhea. Conclusion: The study finding indicates an increased number of patients diagnosed with CD with an excessive sum of secondary ailments, such as anemia, growth failure, growth retardation, malnutrition, and gastrointestinal symptoms.

Antibiotic resistance of E. coli isolates from urine samples of Urinary Tract Infection (UTI) patients in Pakistan.

Drug resistance is becoming alarming with the passage of time worldwide in general and in third world countries in particular. Human urine specimens of patients of urinary tract infection at Sheikh Zayed hospital, Lahore, Pakistan were analyzed for drug resistance in Escherichia coli. A total of 69 Escherichia coli isolates from human urine specimens were obtained and screened for their antibiograms. A total of seven antibiotic resistance profiles were obtained with over 65% of the isolates showing multi-drug resistance. Very high resistance levels were detected against augmentin and gentamicin (87.5 &77.5 % respectively) while imipenem and tazocin recorded the least resistance levels (32.5% and 12.5% respectively) among the isolates.
