Yeasts and humans have had a close relationship for millenia. Yeast have been used for food production since the first human societies. Since then, alternative uses have been discovered. Nowadays, antibiotic resistance constitutes a pressing need worldwide. In order to overcome this threat, one of the most important strategies is the search for new antimicrobials in natural sources. Moreover, biopreservation based on natural sources has emerged as an alternative to more common chemical preservatives. Yeasts constitute an underexploited source of antagonistic activity against other microorganisms. Here, we compile a summary of the antagonistic activity of yeast origin against other yeast and other microorganisms, such as bacteria or parasites. We present the mechanisms of action used by yeasts to display these activities. We also provide applications of these antagonistic activities in food industry and agriculture, medicine and veterinary, where yeast promise to play a pivotal role in the near future.Clay minerals are important reactive centers in the soil system. Their interactions with microorganisms are ubiquitous and wide-ranging, affecting growth and function, interactions with other organisms, including plants, biogeochemical processes and the fate of organic and inorganic pollutants. Clay minerals have a large specific surface area and cation exchange capacity (CEC) per unit mass, and are abundant in many soil systems, especially those of agricultural significance. They can adsorb microbial cells, exudates, and enzymes, organic and inorganic chemical species, nutrients, and contaminants, and stabilize soil organic matter. Bacterial modification of clays appears to be primarily due to biochemical mechanisms, while fungi can exhibit both biochemical and biomechanical mechanisms, the latter aided by their exploratory filamentous growth habit. Such interactions between microorganisms and clays regulate many critical environmental processes, such as soil development and transformation, the formation of soil aggregates, and the global cycling of multiple elements. Applications of biomodified clay minerals are of relevance to the fields of both agricultural management and environmental remediation. This review provides an overview of the interactions between bacteria, fungi and clay minerals, considers some important gaps in current knowledge, and indicates perspectives for future research.Isoprenoids, as the largest group of chemicals in the domains of life, constitute more than 50,000 members. These compounds consist of different numbers of isoprene units (C5H8), by which they are typically classified into hemiterpenoids (C5), monoterpenoids (C10), sesquiterpenoids (C15), diterpenoids (C20), triterpenoids (C30), and tetraterpenoids (C40). In recent years, isoprenoids have been employed as food additives, in the pharmaceutical industry, as advanced biofuels, and so on. To realize the sufficient and efficient production of valuable isoprenoids on an industrial scale, fermentation using engineered microorganisms is a promising strategy compared to traditional plant extraction and chemical synthesis. https://www.selleckchem.com/products/th5427.html Due to the advantages of mature genetic manipulation, robustness and applicability to industrial bioprocesses, Saccharomyces cerevisiae has become an attractive microbial host for biochemical production, including that of various isoprenoids. In this review, we summarized the advances in the biosynthesis of isoprenoids in engineered S. cerevisiae over several decades, including synthetic pathway engineering, microbial host engineering, and central carbon pathway engineering. Furthermore, the challenges and corresponding strategies towards improving isoprenoid production in engineered S. cerevisiae were also summarized. Finally, suggestions and directions for isoprenoid production in engineered S. cerevisiae in the future are discussed. Type 2 diabetes has been associated with increased risk of gynecologic cancers, yet the effect of gestational diabetes mellitus (GDM) on gynecologic cancers is unclear. To examine associations between GDM history and subsequent gynecologic cancers in parous women, and to explore whether gestational hypertension (GH) plays a role in the associations. The population-based cohort study included 15,941 individuals from the Swedish Twin Registry. The history of GDM and GH was ascertained based on self-reports. Incident cases of gynecologic cancers (including cancers of the cervix, uterus, ovaries and other female genitalia) were obtained from the National Patients Registry and the Swedish Cancer Registry. Generalized estimating equation models were applied to analyze associations between GDM and gynecologic cancers. Stratified analysis was used to explore whether associations between GDM and gynecologic cancers differed by GH. Additive and multiplicative interactions were calculated between GDM and GH. Of all participants, 350 (2.2%) had GDM, and 1762 (11.1%) had incident gynecologic cancers. No statistically significant associations were found between GDM and risks of any gynecologic cancers. However, GDM was associated with an increased risk of ovarian cancer (OR = 5.29, 95% CI 1.63-17.19) in women with GH. Interactions between GDM and GH were observed on the additive scale (Attributable proportion due to interaction 0.86, 95% CI 0.42-1.30, P < 0.001). The associations between GDM and risks of gynecologic cancers were not evident, but the effect of GDM on the risk of ovarian cancer was modified by GH. Further validation in larger cohorts is warranted.

Patients with serous endometrial cancer are often diagnosed at earlier disease stage, but remain at higher risk of recurrence and poorer prognosis when compared stage-for-stage with endometrioid subtype endometrial cancer. Serous endometrial cancers are characterized by marked nuclear atypia and abnormal p53 staining in immunohistochemistry. The mainstay of treatment for newly diagnosed serous endometrial cancer includes a multi-modal therapy with surgery, chemotherapy and/or radiotherapy. Unfortunately, despite these efforts, survival outcomes still remain poor. Recently, The Cancer Genome Atlas (TCGA) Research Network classified all endometrial cancer types into four categories, of which, serous endometrial cancer mostly is found within the "copy number high" group. This group is characterized by the increased cell cycle deregulation (e.
