Green manufacturing of catalysts enables sustainable advanced oxidation processes and water treatment processes for removing trace contaminants such as pesticides. An environmentally friendly biosynthesis process produced high-surface-area CuO and NiO nanocatalysts using phytochemicals in the Capparis decidua leaf extract, which served as a reductant and influenced catalyst shape. Capparis decidua is a bushy shrub, widely distributed in dry and arid regions of Africa, Pakistan, India, Egypt, Jordan, Sudan, Saudi Arabia. The synthesized CuO and NiO nanoparticles were characterized by UV-vis spectroscopy (UV-vis), field emission scanning electron microscopy (FESEM), energy-dispersive X-ray spectroscopy (EDS), Fourier transform infrared spectroscopy (FT-IR), and X-ray diffraction (XRD) and thermo-gravimetric analysis/differential thermal analysis (TGA/DTA). The produced nanoparticles were spherical and flower-like in shape and have a characteristic face-centered cubic structure of CuO and NiO. Biosynthesized catalysts were photoactive and degraded recalcitrant pesticide Lambda-cyhalothrin (L-CHT). Photocatalytic degradation of L-CHT was affected by the initial L-CHT concentration, solution pH levels between 5 and 9, and photocatalyst concentration. The L-CHT removal percentage attained by CuO photocatalyst (~99%) was higher than for NiO photocatalyst (~89%). The degradation of L-CHT follows a pseudo-first-order kinetic model, and the apparent rate constant (kapp) decreased from 0.033 min−1 for CuO to 0.0084 min−1 for NiO photocatalyst. The novel flower-shaped nanoparticles demonstrated high stability in water and recyclability for removing L-CHT pesticide contamination in water.

The purpose of this study was to determine the effect of the brief fear of negative evaluation and social anxiety in young adults. Sample of 230 young adults (110=males, 120=females)was taken from different departments of Bahaudin Zakriya University Multan. The study aimed to check the correlation between fear of negative evaluation and social anxiety and differences in fear of negative evaluation and social anxiety among males and females as well as among undergraduate and post graduate students. Brief fear of negative evaluation scale (Leary, M. R., 1983) and Liebowitz social anxiety scale (Michael R. Liebowitz, 1987) was used. Findings revealed positive correlation between social anxiety and Brief fear of negative evaluation. The study concluded that fear of negative evaluation produce social anxiety in young adults (university students). Independent t test confirmed the significant difference among male, females as well as among undergraduate and post graduate on these two variables. Female students showed more fear of negative evaluation and social anxiety than male students; similarly, undergraduate students showed more social anxiety.

Postmenopausal women who have osteoporosis are at increased risk of future fractures. Bisphosphonates are drugs that are used to treat osteoporosis by acting on the osteoclasts to inhibit bone resorption. Several studies have shown that bisphosphonates can maintain or even increase bone mineral density in osteoporosis patients. This review study analyzed the literature on clinical experiments with bisphosphonate therapy in postmenopausal women to determine if these drugs are efficacious in preventing future fractures. Four out of five studies found that women treated with bisphosphonates were at a decreased risk of future fractures, and six of six studies found that bisphosphonate therapy increases bone mineral density relative to placebo control. Although further work is warranted to understand the level of bone mineral density increase that is associated with fracture prevention, this study implies that bisphosphonate therapy can be used to help prevent future fractures in postmenopausal osteoporotic women. The study is significant in that it helps to underscore the efficacy of bisphosphonate therapy in postmenopausal women, and it may be generalizable to other populations with osteoporosis who are at increased risk of fractures.

Background: Social anxiety is common among adolescents in Pakistan and is associated with low self-esteem. Among the recommended treatments, cognitive behavioural therapy (CBT) is effective, and self-help approaches are encouraged. Aim: To determine the effectiveness of culturally adapted CBT-based guided self-help (CACBT-GSH) intervention, using a manual ‘Khushi aur Khatoon’, for treating social anxiety when added to treatment as usual (TAU) compared with TAU only. Method: A total of 76 adolescents with social anxiety aged 13–16 years from six schools in Multan, Pakistan were recruited into this randomized controlled trial. Participants were divided into intervention and control groups in a 1:1 ratio. Social anxiety, self-esteem and fear of negative evaluation were assessed through the Liebowtiz Social Anxiety Scale for children and adolescents, the Rosenberg Self-Esteem Scale and the Brief Fear of Negative Evaluation, respectively, at baseline and at the end of the study. Guided self-help using culturally adapted CBT (CACBT)-based self-help manual (eight sessions, one session per week) was provided to the intervention group. The effect of the CACBT-GSH intervention was analysed with ANCOVA. Results: There was a statistically significant difference between the intervention and the control groups in favour of intervention. Participants in the intervention group showed reduced symptoms of social anxiety (p < .001), fear of negative evaluation (p < .001) and enhanced self-esteem (p < .001). Conclusion: The study demonstrated the effectiveness of CACBT-based guided self-help intervention in treating social anxiety and addressing the symptoms associated with it.
