Background: Constipation is one of the most common gastrointestinal complaints during pregnancy. Consuming fruits and vegetables is often the first line of treatment due to their fiber content. Therefore, the purpose of the present study was to determine the effect of combined fig-walnut syrup on functional constipation (FC) and quality of life (QoL) in pregnant women.

- Electrospun fibers, while desirable for their features, are mechanically fragile and require support, leading to the development of bio-based multilayer films using strong sage seed gum-gelatin as outer layers and zein-pomegranate extract in the middle.
- These multilayer films showed improved thickness (0.18 to 0.25 mm), tensile strength (increased from 60.8 to 70.2 MPa), and reduced permeability to water vapor and oxygen by 72.4% and 82.6%, respectively.
- The research demonstrates significant enhancements in antioxidant activity and antimicrobial properties as the electrospun layer thickness increases, indicating potential for sustainable packaging solutions.
In the current study, the sage seed gum/gelatin-TiO (SG/Ge-TiO) nanocomposite films were prepared. Their physical, mechanical, chemical, barrier, surface, structural, and microbial characteristics are determined as a function of different ratios of sage seed gum (SG) to gelatin (1 to 2, 2 to 1 and 1 to 1) and different concentrations of TiO nanoparticles (0, 2, 4 % based on biopolymer (w/v)). The results indicated increases in the tensile strength, elongation at break, thickness, brightness (L*), whiteness index (WI), and contact angle, as gelatin content and concentration of TiO nanoparticles increase.

Specifically, it investigated the associations between the dietary inflammatory index (DII) and the energy-adjusted dietary inflammatory index (E-DII) with sperm motility, morphology, and count in men undergoing routine semen analysis.
Methods: A cross-sectional study was conducted with 144 men enrolled, where semen samples were collected and evaluated according to the 2010 World Health Organization guidelines.
Background: Weight loss failure after bariatric surgery imposes great stress on patients and surgeons and great costs on healthcare systems. The literature review shows that weight loss failure is the most common cause of redo bariatric surgery. Therefore, identifying the predictors of weight loss failure in patients in the early stages can help bariatric surgeons.
