Article Synopsis
  • The vaginal microbiota plays a significant role in the health of women and newborns, but its ecological dynamics and stability are not fully understood.
  • This study investigates how nutritional resources, particularly glycogen and sialic acid, influence the composition of vaginal bacterial communities, highlighting the connection between resource availability and bacterial behavior.
  • Using a new mathematical model, the research finds that bacteria associated with bacterial vaginosis (BV) thrive due to their exclusive access to certain nutrients, which helps them resist changes in their community structure, providing insights for potential BV prevention strategies.

To date, nearly 300 lentiviral-based gene therapy clinical trials have been conducted, with eight therapies receiving regulatory approval for commercialization. These advances, along with the increased number of advanced-phase clinical trials, have prompted contract development and manufacturing organizations (CDMOs) to develop innovative strategies to address the growing demand for large-scale batches of lentiviral vectors (LVVs). Consequently, manufacturers have focused on optimizing processes under good manufacturing practices (GMPs) to improve cost-efficiency, increase process robustness, and ensure regulatory compliance.

The effective measurement of temperature in living systems at the nano and microscopic scales continues to be a challenge to this day. Here, we study the use of 2-(anthracen-2-yl)-1,3-diisopropylguanidine, 1, as a nanothermometer based on fluorescence lifetime measurements and its bioimaging applications. In aqueous solution, 1 is shown in aggregated form and the equilibrium between the two main aggregate types (T-shaped and π-π) is highly sensitive to the temperature.

Two series of boron derivatives with propiolamidinato ligands, [BPh{C(C≡CAr)(NR)}] (Ar = Ph, -MeOPh, -FPh, -MeNPh, or phen; R = iPr or -tolyl), were synthesized and structurally characterized. The corresponding propiolamidine (or propargylamidine) proligands have been obtained through sustainable methods. One is the catalytic hydroalkynylation of diisopropylcarbodiimide with different terminal alkynes, using simple ZnEt as a precatalyst.

Public health and safety measures (PHSM) made in response to the COVID-19 pandemic have been singular, rapid, and profuse compared to the content, speed, and volume of normal policy-making. Not only can they have a profound effect on the spread of the disease, but they may also have multitudinous secondary effects, in both the social and natural worlds. Unfortunately, despite the best efforts by numerous research groups, existing data on COVID-19 PHSM only partially captures their full geographical scale and policy scope for any significant duration of time.
