Therapeutic Effects of Pimpinella anisum Fruit Extract on Polycystic Ovary Syndrome in a Rat Model: Emerging Role of Inflammatory Responses and Oxidative Stress.

Background: Polycystic ovary syndrome (PCOS) is the most common gynecological endocrine disorder. Objectives: This study evaluated the therapeutic effects of Pimpinella anisum L. (P. anisum) fruit on pro-inflammatory cytokines, oxidative stress markers, and ovarian tissue structure in a rat model of PCOS. Methods: After inducing PCOS, female Wistar rats were randomly divided into control and PCOS groups. They orally received daily doses of normal saline or hydro-alcoholic extract of P. anisum at two doses (200 and 400 mg/kg) for 21 days. At the end of the treatment period, ovarian and liver tissues were collected to measure lipid peroxidation, antioxidant status, TNF-α, IL-6 mRNA expression, and its content. Additionally, histopathological examinations of the ovarian tissue were conducted. Results: Our findings revealed a dose-dependent change in the biochemical and histopathological parameters. Treatment with P. anisum resulted in a significant decrease in TNF-α and IL-6 mRNA expression levels and their content in the ovarian and liver tissues. It also reduced MDA levels while increasing SOD and GPx activity in both ovarian and liver tissues of PCOS rats. Furthermore, the number of follicular cysts in the PCOS rat model was significantly reduced. Conclusions: The beneficial effects of P. anisum in PCOS rats are partly attributed to the inhibition of inflammatory and oxidative stress markers in ovarian tissue. These findings suggest that P. anisum could be a potential candidate for the treatment of PCOS disorders.

Knowledge, attitudes, and practices regarding brucellosis in a rural population: A cross-sectional study.

Brucellosis is recognized as a significant global zoonotic infection that disproportionately affects low-income settings. A community cross-sectional survey was carried out in a rural setting of northwest Iran between February and May 2023. Rural individuals were interviewed according to a questionnaire with questions about demographic characteristics, knowledge, attitudes, and practices relating to human brucellosis. We employed descriptive statistics to study knowledge, attitudes, and practice patterns. In addition, we applied a multivariable logistic regression model to assess potential predictors of knowledge, attitudes, and practice related to brucellosis using odds ratios and 95% confidence intervals. Among 700 participants, 91.1% were aware of brucellosis, and 85.7% identified cows, sheep, and goats as primary transmission sources. 75.6% and 78.7% recognized transmission risks via unpasteurized and raw milk products. 60.5% understood the benefits of boiling milk and using gloves. Attitudinally, 64.3% perceived higher risk for livestock owners and supported practices like milk pasteurization (70.5%), protective gear (84.4%), handwashing (92.2%), and animal vaccination (71.0%). 90% expressed a need for more information. In practice, 44.8% exclusively consumed boiled and pasteurized milk, 37.8% consumed fresh cheese, and 92.2% solely consumed thoroughly cooked animal meat. Logistic regression revealed that higher education and no prior history of the disease correlated with good knowledge and attitudes, while older participants displayed inappropriate practices compared to their younger counterparts. This study highlights the reasonably high awareness of brucellosis, particularly regarding transmission sources and preventive measures. However, the gaps in knowledge, attitudes, and practices still exist, with education level emerging as a significant factor. To improve prevention practices, tailored interventions addressing age-related disparities are necessary.

One-pot synthesis of polyhydroquinoline-1,2,3-triazole hybrids in deep eutectic solvent as anti-leishmanial agents and molecular modeling studies.

The novel hybrids with 1,2,3-triazole and polyhydroquinoline scaffolds were successfully synthesized by multicomponent reaction of propargyloxybenzaldehyde, 1,3-cyclohexadione, ethylacetoacetate and ammonium acetate followed through click reaction in the presence of deep eutectic solvent ChCl/ZnCl2 as an efficient catalyst. Their anti-leishmanial activity was evaluated against amastigote and promastigote forms of L. tropica, L. major, and two different species of L. infantum. Furthermore, to determine the cytotoxicity of the hybrids, they were evaluated against the murine macrophage cell line J774.A1. Based on the results, three hybrids showed the highest antileishmanial activity. However, they revealed low cytotoxicity. Hybrid 6j was the most potent compound against both the forms of all leishmanial types, with IC50 = 13.5 and 11.9 µg/mL for L. major, 37.5 and 25 µg/mL for L. tropica, 17.5 and 20 µg/mL for L. infantum (MCAN/IR//96/LON49) and 35.5 and 30 µg/mL for L. infantum (MCAN/ES/98/LIM-877), respectively. Finally, molecular docking and molecular dynamics simulations were also performed to identify possible mechanism antileishmanial activity.Communicated by Ramaswamy H. Sarma.

Major depressive disorder: Biomarkers and biosensors.

Depressive disorders belong to highly heterogeneous psychiatric diseases. Loss of in interest in previously enjoyed activities and a depressed mood are the main characteristics of major depressive disorder (MDD). Moreover, due to significant heterogeneity in clinical presentation and lack of applicable biomarkers, diagnosis and treatment remains challenging. Identification of relevant biomarkers would allow for improved disease classification and more personalized treatment strategies. Herein, we review the current state of these biomarkers and then discuss diagnostic techniques of aimed to specifically target these analytes using state of the art biosensor technology.
