Background: The escalating rate of diabetes' has prompted researchers around the world to explore for early markers. A deficit of functional β-cell mass plays a central role in the pathophysiology of type 2 diabetes. The REG (Regenerating) gene, encoding a 166 amino acid REG protein was discovered in rats and humans which is released in response to β-cells damage and play a role in their regeneration. The objective of this study was to characterize serum levels of REG Iα proteins in type 2 diabetic patients as indicator of β-cell apoptosis as well as regeneration.
Methods: Unrelated type 2 diabetic patients (n = 55) of different age groups and disease duration were recruited from the Medical OPD of PNS Shifa Hospital. Age and sex matched non diabetic controls (n = 20) without family history of diabetes were selected from the same setting. Demographical details were recorded on a structured questionnaire. Biochemical parameters like FBG, HbA1c, TC and TG levels were measured. Serum levels of REG Iα protein were determined by ELISA.
Results: Levels of REG Iα protein were found significantly raised in type 2 diabetic patients compared to controls (p < 001). Patients with short duration of the disease had higher levels of REG Iα as compared to patients with longer duration of the disease. Although the patients were on anti hyperglycemic agents, a positive correlation was found between REG Iα serum levels, FBG and HbA1c levels. Patients with higher BMI had higher levels of serum REG Iα levels. Serum TC, TG and Hb levels showed no correlation.
Conclusion: REG Iα may be used as a marker/predictor of type 2 diabetes especially in the early stages of the disease.

Article Synopsis
- The study explores how disruptions in the cervicovaginal microbiome, particularly through the production of indoleacrylic acid (IAA), influence the development of gynecological cancers like endometrial cancer (EC).
- Researchers found that IAA production from certain bacterial species can promote tumor growth and affect immune cell dynamics in both patients and mouse models.
- The results indicate a connection between higher levels of IAA, increased IDO1 expression, and altered immune responses, suggesting that certain bacterial species may contribute to immune tolerance in endometrial cancer.
A comparative analysis of the cost-utility of the Philippine tax on sweetened beverages as proposed and as implemented.

Article Synopsis
- The Philippine government implemented a tax on sweetened beverages in 2018 to combat rising obesity rates, but the final tax design was influenced by the beverage industry, making it less effective than initially proposed.
- A study used dietary and pricing data to estimate the health and economic effects of the proposed versus the implemented tax, finding that the implemented tax resulted in significantly lower reductions in beverage consumption, body mass index, health-adjusted life years, healthcare savings, and tax revenue.
- Although both tax versions aim to improve public health and save costs, the implemented tax will likely provide fewer benefits compared to the originally proposed tax due to industry influence on policy.
Microwave-assisted autohydrolysis of avocado seed for the recovery of antioxidant phenolics and glucose.

This study describes the valorization of avocado seed (AS) within a green biorefinery concept using microwave-assisted autohydrolysis. After the treatment at temperatures of 150-230 °C for 5 min, the resulting solid and liquor were characterized. The temperature of 220 °C led to the simultaneous optimal values of antioxidant phenolics/flavonoids (42.

Purpose: Regular physical exercise may result in many benefits to patients with chronic kidney disease (CKD) on hemodialysis (HD), including gut microbiota modulation and solute removal. The study aimed to evaluate the effects of two programs of intradialytic exercises on uremic toxins plasma levels in HD patients.
Methods: In experiment 1, twenty HD patients [12 men, 44.
