Evaluation of Aloe Vera Gel Combined with Cinnamon Oil with Antibacterial Activity for Wound Healing Application.

Treatment of chronic wounds has been shifted to traditional approaches due to surge in antibiotic resistance. Wounds that fail to heal satisfactorily may result in the amputation of the organ. In this research work, cinnamon oil (CO) and aloe vera (AV) that have been traditionally used as antibacterial agents are combined in a unique gel (COVA) and its antibacterial activity has been evaluated through in vitro and in vivo studies. Antibacterial activity was measured through disk diffusion and agar dilution method against Pseudomonas aeruginosa and Staphylococcus aureus. To check antibacterial and wound healing activity, diabetic excision wound healing rat model was used. Wound closure, wound contraction, tissue hydroxyproline content, antioxidant capacity (TAC), and malondialdehyde (MDA) level were monitored. The minimum inhibitory concentrations of CO + AV for bacterium P. aeruginosa and S. aureus were 100 and 200 µg/ml, respectively. After 14 days, the wounds covered with COVA therapy reached to nearly full wound closure (79% wound contraction) compared to control. The collagen content and level of TAC increased significantly (P < 0.05) in treated groups; therefore, 25% fast healing was observed in wounds treated with CO and AV gel combined. Reduced levels of tissue MDA were observed in all treated groups and specially wound covered with COVA (0.43 mM/mg in control vs 0.25 mM/mg in COVA). Histopathological examination also supported the outcomes. Significantly elevated increase in the level of hydroxyproline was found in rats of COVA treatment group (37.1 ± 0.44). Combination of CO and AV can be potentially used to prevent infection in wound; as these herbal agents not only inhibit the growth of pathogenic bacteria but also accelerate tissue repair.

Reversed intestinal malrotation presenting as bowel obstruction in pregnancy: Case report and literature review.

Introduction: Midgut malrotation is a congenital condition caused by insufficient normal intestinal rotation following physiologic gut herniation. Reverse rotation of the midgut is the rarest kind of intestinal malrotation, accounting for about 2%-4% of all cases. Case presentation: We report a case of a 26-year-old South Asian gravida with a previous history of quadruple miscarriage and ovulation induction, presented as intestinal obstruction due to reverse malrotation. An MRI of the abdomen indicated that the mesentery had become twisted around the SMA, resulting in a "whirlpool" pattern. Open exploration was done to accomplish lysis of restricting bands with appendectomy. Conclusion: Intestinal obstruction in pregnancy is uncommon, but when unrecognized in a timely fashion, it is associated with significant maternal and fetal mortality. A simple release of constricting bands without antimesenteric transposition seems to be the safest option in this situation.

Doxorubicin Loaded Gold Nanoparticles Mitigate Liver Fibrosis and Inflammatory Cytokines Gene Expression in Rat.

BACKGROUND: Gold nanoparticles have the potential to be used as a carrier in drug delivery system due to their small size, large surface area and short circulation time in blood. OBJECTIVE: This study aims that doxorubicin conjugation with gold nanoparticles (AuNPs) may reduce its toxicity as well as improve therapeutic efficacy. METHODS: Five groups of Albino rats were used; 1: healthy control, 2: Injured, 3: injured and treated with Dox, 4: Injured and treated with AuNPs, 5: Injured and treated with AuNPs: Dox. At the end of the experiment, blood and liver tissues were processed for biochemical and histopathological analysis. The expression of collagen, HO-1, IL-6 and TNF-α genes involved in liver fibrosis was observed through real-time PCR. RESULTS: At the end of the experiment, it was observed that the body weights of DOX treated rats decreased by 0.72%, however, AuNPs and Au: DOX treated rats were 15.3% and 29.13% respectively. The percentage of liver protection determined through alanine aminotransferase and aspartate aminotransferase levels in DOX, AuNPs and AuNPs: DOX treated groups were 39.21%, 79.26%, 98.17% and 47.77%, 84.17%, 97.92% respectively. That represents better recovering liver in Dox-AuNPs treated rats compared to others. Histopathological and gene expression studies further support the findings. The mRNA expression levels of inflammatory and oxidative stress related genes HO-1, IL-6 and TNF-α were upregulated in the injured group but downregulated in the treated group. CONCLUSION: As depicted through biochemical, histopathological and gene expression studies, Au: DOX conjugate group seems to be protective against liver fibrosis.

Recent advances in bioremediation of heavy metals and persistent organic pollutants: A review.

Heavy metals and persistent organic pollutants are causing detrimental effects on the environment. The seepage of heavy metals through untreated industrial waste destroys the crops and lands. Moreover, incineration and combustion of several products are responsible for primary and secondary emissions of pollutants. This review has gathered the remediation strategies, current bioremediation technologies, and their primary use in both in situ and ex situ methods, followed by a detailed explanation for bioremediation over other techniques. However, an amalgam of bioremediation techniques and nanotechnology could be a breakthrough in cleaning the environment by degrading heavy metals and persistant organic pollutants.

Fungal and bacterial assisted bioremediation of environmental toxicant (N-[2-[3-chloro-5-(trifluoromethyl)-2-pyridinyl] ethyl]-2-(trifluoromethyl) benzamide) holding benzamidic genesis elucidating the eco-friendly strategy.

Fluopyram (FLP) containing benzamidic genesis utilized for seed detoxification and as a foliar application is associated with low profound toxicity in mammals but long-term toxicology investigations have revealed that FLP can stimulate tumor growth. FLP attenuation has been the first time scrutinized employing microorganisms originally identified from soils. Biodegrative assays of four fungal strains; Aspergillus fumigatus (AFu), Aspergillus terreus (AT), Aspergillus flavus (AF), Aspergillus niger (AN), and three bacterial strains: Streptococcus pneumoniae (SP) Streptococcus pyogenes (SPy), and Escherichia coli (EC), were employed. Ten milligrams per liter FLP concentration was made employing separately microbe and analyzed for 35 days. The analytical technique was inclusive of ultraviolet-visible spectrophotometric and high-performance liquid chromatography procedure endeavored to test FLP biodegradation. SP and AT exhibited maximal potentiality to metabolize FLP. HPLC is indicative of several metabolites formations. FLP degradation by AFu, EC, SPy, AN, AF, AT, SP was observed to be 24.2%, 82.7%, 89.8%, 90.7%, 91.3%, 95.4%, and 99.3%, explicating the efficacy of all strains employed in FLP degradation. Current investigations are indicative of significant bioremediation strategies for xenobiotic mitigation. Furthermore, the current examinations are inclusive of the augmentation of biodegradative assays to be utilized on a large scale for efficient environmental management cost-effectively and sustainably.

Cross-cultural prevalence of sleep quality and psychological distress in healthcare workers during COVID-19 pandemic.

BACKGROUND: Poor quality sleep and emotional disturbances are expected in times of crisis. COVID-19 has severely impacted healthcare worldwide and with that comes the concern about its effects on healthcare workers. The purpose of the present study was to assess sleep quality and psychological distress in healthcare workers during the COVID-19 pandemic. METHODS: The present work is a multi-centric cross-sectional study targeting healthcare workers from India, Pakistan, and Nepal. It used an online version of the Pittsburg Sleep Quality Index and the General Health Questionnaire, and data were analyzed using SPSS V.24. RESULTS: A total of 1790 participants completed the questionnaire. Of the 1790 participants, 57% reported poor sleep quality, and 10% reported a high level of psychological distress. A cross-cultural comparison found some differences between the different groups of participants. The details of the differences were further explored in the article. CONCLUSION: The present study highlights that a significant proportion of healthcare workers are affected by poor sleep quality and psychological distress during the COVID-19 pandemic. It also emphasizes the imperative to provide them with psychosocial support to avoid potential short- and long-term psychological consequences of these troubling times.
