Roots of 3-days old <i>B. juncea</i> seedlings were inoculated with <i>S. indica</i> and raised in toxic Cd concentrations (10 µM, 30 µM and 50 µM Cd) till 12 days after inoculation in plant growth chamber with conditions of 16-h light/8-h dark photoperiod, temperature 25 °C (± 2 °C) and 80% relative humidity. The seedlings were tested for various morpho-physiological parameters like seed germination, plant biomass and %age heavy metal tolerance index. Also, various non-enzymatic antioxidants like vitamin A, vitamin C, phenols, flavonoids, total soluble sugars, reducing and non-reducing sugars were analyzed. Cd led to reduction in the % age germination of <i>B. juncea</i> seeds<i>. Serendipita indica</i> inoculation incremented the growth parameters like fresh weight, dry weight, root length, shoot length which were diminished by Cd stress. Enhancement of 20.66% in root length was observed in inoculated and Cd stressed seedlings. The content of phenols increased under unstressed conditions by 26.6% and by 55.29% under Cd stressed conditions in <i>S. indica</i> inoculated seedlings along with increasing contents of vitamin A and C. Overall, the content of carbohydrates was enhanced with <i>S. indica</i> inoculation.

In recent years, there has been increasing concern about the health problems associated with HPV infection. To better understand the mechanisms by which high-risk human papillomavirus infection leads to cervical cancer, many studies have begun to explore the role of the vaginal microenvironment in this context. The female vagina is an open cavity with a special anatomical structure, which constitutes the first barrier to protect the vaginal microenvironment. At the same time, the female reproductive tract is a typical micro-ecosystem with a wide variety of microflora, which maintains a dynamic and balanced relationship of symbiosis, coexistence, and mutual control with the external environment and the host. Hormonal changes during the physiological cycle, especially estrogen, have an important influence on the structure and stability of the vaginal flora. In addition, the vagina has an important role in immune homeostasis, where the immune system plays a crucial role in maintaining tissue homeostasis, eliminating pathogens, and avoiding barrier damage. When a pathogen such as human papillomavirus enters the vagina, the immune system initiates an associated immune response to clear the virus and restore tissue health. However, in some cases, the immune system may not be able to effectively respond to human papillomavirus infection, leading to the development of persistent infections. Dysregulation of vaginal microecology may be an important factor in persistent human papillomavirus infection. This review focuses on this topic by describing the vaginal microenvironment, human papillomavirus, and the mechanisms involved in influencing the vaginal microecology causing persistent human papillomavirus infection and thus accelerating cervical carcinogenesis.</p>","PeriodicalId":13316,"journal":{"name":"Indian Journal of Microbiology","volume":"431 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142220318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The carbon nanotube (CNT)-based drug delivery systems for specific OC therapy are highlighted in this review. These systems have several advantages against free drugs, including nontoxicity, biological compatibility, high biodegradability, increased therapeutic impact, and non-inflammatory effects. Crucially, functionalized CNTs with particular ligands like cancer antigen (CA125), Human epididymis protein 4 (HE4), Mucin 1, and folic acid (FA) allow for selective targeting of OC and ultimately increase therapeutic potential in comparison to their nonfunctionalized counterparts.

For <i>P. vivax</i> disease severity, the data related to immunological and inflammatory status in human host is very limited. In the present study clinical parameters, cytokine profile and <i>integrin</i> gene were analyzed in <i>P. vivax</i> clinical patients. A total of 169 <i>P. vivax</i> samples were collected and categorized into severe vivax malaria (SVM; n = 106) and non-severe vivax malaria (NSVM; n = 63) according to WHO severity criteria. We measured host biomarker levels of interferon (IFN-γ), superoxide dismutase (SOD-1), interleukins viz. (IL-6, IL-10), and tumor necrosis factor (TNF-α) in patient plasma samples by ELISA for pro- and anti-inflammatory cytokines in severe malaria. Host <i>integrin</i> gene was genotyped using PCR assay. In our study, thrombocytopenia and anemia were major symptoms in severe <i>P. vivax</i> patients. In analyzed SVM and NSVM groups a significant increase in cytokine levels (IL-10, IL-6, and TNF-α) and anti-oxidant enzyme SOD-1 was found. Our study results also showed a higher pro-inflammatory (TNF-α, IL-6 and IFN-γ) to anti-inflammatory (IL-10) cytokine ratio in severe vivax patients. <i>Integrin</i> gene showed no mutation with respect to thrombocytopenic patients among clinically defined groups. It was observed that severe vivax cases had increased cytokine levels irrespective of age and sex of the patients along with thrombocytopenia and other clinical manifestations.
