Infertility-related Stress and Marital Satisfaction among Pakistani Infertile Individuals

Infertility is a reproductive health problem that is widely researched with reference to numerous psychological concerns faced by infertile individuals. Childless couples face numerous personal and social consequences with every passing day. Among them, immediate family members' expectations to carry on the family’s name significantly weigh down marital union in the form of marital dissatisfaction among infertile individuals. Therefore, the relationship between stress related to infertility and its impact on the marital union, individuals (N = 150) of 18-40 years (M = 29.19, SD = 5.59) were taken from Rawalpindi, Islamabad, and Attock. The sample was approached at infertility centers, hospitals, offices, and their homes using snowball and purposive sampling techniques. Fertility Problem Inventory (FPI) and ENRICH Marital Satisfaction (EMS) Scale was administered on the sample. The results established satisfactory Cronbach alpha reliabilities (α = .63 to α = .93) for all scales. Hypotheses testing revealed that stress due to infertility negatively affects the marital satisfaction of infertile individuals and accounted for a 7% variance. Lastly, non-significant gender differences were observed across the variables of the study. These findings would be helpful in understanding the dynamics of stress, faced by childless individuals and would be beneficial in the investigation of cultural buffering factors. Non-significant gender differences across infertility-related stress further highlight the significance of devising and providing intervention-based programs and therapies for both men and women to cope with the stress and strengthen the marital union of infertile individuals

Sewage Treatment Using Nanoparticles

This chapter provides a brief overview of nanomaterials, including classification, shape and structure, nanomaterial types, and applications in the degradation of recalcitrant organic contaminants. With the rapid advancement of nanotechnology science, the use of nanomaterials in environmental applications, particularly water treatment, has piqued the scientific community’s interest in recent decades. Nanomaterials have unique properties such as surface-to-volume ratio, quantum effect, low band-gap energy, and so on, which enhance catalytic performance. Wastewater treatment is a critical task of the twenty-first century since it protects the health of our environment and living beings. Because of its ability to affect both living and nonliving organisms, wastewater is always viewed as a serious source of environmental contamination. Many physical, biological, and chemical modes of treatment are implied to comply with wastewater discharge standards set by competent national agencies for environmental protection

Insights into the consequence of (Al–Zn) dual-doping on structural, morphological, and optoelectrical properties of CdO thin films

The present study explores the structural, morphological, optical, and electrical properties of spray pyrolyzed (Al–Zn) dual-doped CdO thin films. The un-doped and (Al–Zn) dual-doped CdO thin films have been deposited on glass substrate using spray pyrolysis route at 325 °C. The physical properties of the doped samples were analyzed as a function of Zn concentration (2–5 mol%) with constant Al (3 mol%) concentration. XRD analysis confirms the successful incorporation of (Al–Zn) dual-doping into CdO crystal as well as the polycrystalline nature was evident. No phase transitions were apparent from XRD data while revealing the single cubic structure of all the samples. The surface morphology of the samples studied by SEM. It shows the formation of rock-shaped microstructure and the variation of grain size with doping concentrations. Optical analysis was done using UV–vis spectroscopy within the range of 300–1200 nm. Maximum value of transmittance was attained for 3% (Zn–Al)-doped CdO sample. The dual doping exhibits the broadening of band gap values (2.61–3.84 eV) whereas a decrease in extinction coefficient was noticed as a function of Zn doping concentration. Electrical analysis was done using the four-probe method and a high resistivity was seen for higher Zn concentration. Obtained results and precise comparison with some similar films suggested that 2% Zn and 3% Al co-doping can be a suitable candidate for optoelectronic devices

Effect of gamma irradiation on chemical composition, antioxidant activity, antibacterial activity, shelf life, and cytotoxicity in the peels of two mango varieties grown in Bangladesh

Mango (Mangifera indica) is perhaps the most notable sound natural product, however short-lived. A few synthetic compounds like calcium carbide, pesticides, formalin and calcium-based arrangements have been utilizing for its protection, notwithstanding, those synthetic compounds are perilous for our human wellbeing. Besides, mango strip is a food-handling by-product that is discarded since it isn't economically reasonable. For this study, the nutritional, antibacterial, and antioxidant properties of peels from two mango cultivars (Amrapali, and BARI-11) were analyzed with four doses (0.5, 1.0, 1.5, and 2 kGy) of gamma irradiation. The impacts of radiation on storage quality and life span of usability were likewise investigated. Mango peels were found to have many phytochemicals. Be that as it may, radiation altogether impacted tested parameters like fat, protein, carb, fiber, sugar, energy, soluble solids, etc. in both of the mango peels. On the other hand, the peel samples showed 50% DPPH scavenging activity at varied dosages. Moreover, samples exposed to 1.5 kGy of radiation showed higher antioxidant activity. At a radiation dose of 1.5 kGy, amrapali peel proved to be less hazardous to brine shrimp lethality assay than other samples. The widest inhibitory zones against Pseudomonas sp. were obtained at a dosage of 150 µg/disc. After two weeks of storage, the 1.5 kGy radiation dosage left the mangoes' texture firm, indicating that it was extending the fruit's shelf life by greatly reducing the microbial attack. Thus mangoes could be preserved using radiation without significantly affecting their nutritional value

Guide on Diabetes and COVID-19 for Healthcare Professionals in Bangladesh

The world is suffering from a pandemic of coronavirus disease-2019 (COVID-19), and people with diabetes mellitus (DM) are more vulnerable to the serious effects of the COVID-19. This interaction is alarming, considering the high transmission rate of COVID-19 and the global prevalence of DM. Considering the importance of the link between COVID-19 and DM, Bangladesh Diabetic Association has formed a panel of national and international experts in the field of public health, diabetes, and endocrinology to provide some evidence-based guidance for the prevention and care of people with DM during the COVID-19 pandemic
