Biodegradation is utilizing microorganisms to degrade materials into products that are safe for the environment, such as carbon dioxide, water, and biomass. The current study aims to isolate and characterize bacteria with polyethylene terephthalate (PET) degradation ability isolated from Shatt al-Arab water and sewage from Basra, the bacteria were identified as Klebsiella pneumonia. According to the findings, the isolates showed a highly significant difference in degradation of PET (24% during 7 days) and the percent of degradation increased to 46% at 4 weeks compared to the control. The study also involved determining the optimum temperature of K. pneumonia growth, which was 37°C, while the preferred pH was 7-8. The research revealed that PET biodegradation by K. pneumonia can be used as a suitable and environmentally friendly tool.

About 12,000 chemical compounds isolated from medicinal plants and used to conduct crucial biological functions. These phytochemicals offer long-term health benefits for humans, thus they can be used effectively for treat a variety of human ailments. The goal of this study was to assess the in vitro free radical scavenging and antibacterial activities of glycoside, flavonoid and alkaloid extracts of Tilia cordata plant. According to the findings, flavonoid extract exhibits strong inhibitory action against Staphylococcus aureus but no activity against Escherichia coli. The free radical scavenging activity exhibited that the flavonoid extract was more effective in inhibiting lipid peroxidation more than alkaloid extract, whereas the glycoside extract had no antioxidant activity.

Background: Burnout affects >50% of physicians, especially women. This study aimed to examine how negative workplace interactions can predict burnout, and whether positive social interactions can mitigate risk. Materials and Methods: In a study of 1627 physician mothers who responded to a survey by the Physician Moms Group, an online Facebook group, we first examined the association between workplace sexual harassment and burnout. In an embedded experiment, we then measured the causal impact of priming perceived social support and connectedness on the three dimensions of employee burnout. Results: Two-thirds of respondents reported having experienced sexual harassment in the past year. Sexual harassment by patients was associated with 0.27 points higher emotional exhaustion, one dimension of burnout (95% confidence interval [CI] 0.12-0.41), equivalent to the predicted impact of an additional 22 weekly work hours on emotional exhaustion. Sexual harassment by patients was also associated with 0.40 points higher patient depersonalization, another dimension of burnout (95% CI 0.27-0.53). Sexual harassment by colleagues was associated with 0.16 points higher emotional exhaustion (95% CI 0.02-0.30), but not other dimensions of burnout. We found no significant relationship between experiences of sexual harassment and levels of personal accomplishment (the third dimension of burnout) among this sample. Priming physician mothers to reflect on their connectedness with other physician mothers significantly increased their sense of personal accomplishment. The priming intervention did not yield a significant effect on emotional exhaustion or depersonalization. Conclusions: Negative and positive social interactions each affect different dimensions of burnout. Sexual harassment-a pervasive type of negative social interaction-strongly predicts emotional exhaustion and depersonalization. Reflecting on social connectedness-a type of positive social interaction-can improve one's sense of personal accomplishment with an effect similar in magnitude to more intensive in-person interventions, suggesting that social connectedness through online groups merits further consideration as a tool to mitigate burnout.

Herpes are a group of similar viruses that are responsible for a number of infecting diseases, the most important of which are herpes simplex, herpes zoster and pseudopox. Resistance to traditional antiviral medications is becoming increasingly common, making treatment of such infections even more difficult. For example, the usage of nucleoside analogues like acyclovir to target the DNA-polymerase of the virus on a regular and long-term basis promotes the generation of resistant viruses. As a result, a different treatment is required. Natural products, such as herbal remedies, have been shown to have in vitro and in vivo activity against herpes viruses, and have shown to be a valuable source for new antivirals development and separation. The goal of this review is to highlight the most promising extracts and pure chemicals obtained from plants and marine species that have in vivo anti-herpes simplex virus (HSV-1 and HSV-2) action. Natural products as new anti-HSV medications offer a number of benefits, including fewer side effects, minimal toxicity, and lowered resistance, and a variety ways of deed.

Objectives: The coronavirus disease 2019 (COVID-19) pandemic has presented extreme challenges for health care workers. This study sought to characterize challenges faced by physician mothers, compare differences in challenges by home and work characteristics, and elicit specific needs and potential solutions. Methods: We conducted a mixed-methods online survey of the Physician Moms Group (PMG) and PMG COVID19 Subgroup on Facebook from April 18th to 29th, 2020. We collected structured data on personal and professional characteristics and qualitative data on home and work concerns. We analyzed qualitative data thematically and used bivariate analyses to evaluate variation in themes by frontline status and children's ages. Results: We included 1,806 participants in analysis and identified 10 key themes. The most frequently identified need/solution was for Community and Government Support (n = 545, 47.1%). When comparing frontline and nonfrontline physicians, those on the frontline more frequently raised concerns about Personal Health and Safety (67.8% vs. 48.4%, p

The letter presents a study on the impact of COVID-19 on mental health of physician mothers To quantify the mental health impact of the COVID-19 pandemic on a predominantly U S cohort of physician mothers, authors surveyed the Physician Moms Group on Facebook from April 18 to April 29, 2020, after receiving approval from the institutional review board at Stanford University The rates of anxiety among physician mothers in this study appear substantial;for context, in the general U S population in normal circumstances, about 19% of adults had any anxiety disorder in the past year (PsycInfo Database Record (c) 2021 APA, all rights reserved)
