Perfluoroalkyl Substances (PFAS) Exposure and Preeclampsia Risk: Impaired Angiogenesis Through Suppression of VEGF Signaling.

Per- and polyfluoroalkyl substances (PFAS) are linked to preeclampsia (PE), a condition involving abnormal angiogenesis. Prior research on this association has been inconclusive. We investigated the relationship between maternal PFAS exposure and PE risk in Wisconsin.

Regulatory T cell therapy is associated with distinct immune regulatory lymphocytic infiltrates in kidney transplants.

Background: Adoptive transfer of autologous regulatory T cells (Tregs) is a promising therapeutic strategy aimed at enabling immunosuppression minimization following kidney transplantation. In our phase 1 clinical trial of Treg therapy in living donor renal transplantation, the ONE Study (ClinicalTrials.gov: NCT02129881), we observed focal lymphocytic infiltrates in protocol kidney transplant biopsies that are not regularly seen in biopsies of patients receiving standard immunosuppression.

Zinc-lysine and iron-lysine mitigate chromium toxicity in pearl millet (Pennisetum glaucum) through modulating photosynthetic and antioxidant system and inhibiting chromium uptake and translocation.

Chromium (Cr) is an ever-present abiotic stress that negatively affects crop cultivation and production worldwide. High rhizospheric Cr concentrations inhibit nutrients uptake and their translocation to aboveground parts, thus can affect the growth and development of crop plants. This experiment was designed to evaluate the effects of sole and combined zinc-lysine and iron-lysine applications on photosynthetic efficacy, antioxidative defense, oxidative stress, and nutrient uptake and translocation under Cr stress.

Adsorption and Sensing Performance of Transition Metal Decorated Graphene Quantum Dots for AsH, NH, PH, and HS.

We have conducted a systematic study employing density functional theory (DFT) and quantum theory of atoms in molecules (QTAIM) to explore the gas sensing capabilities of nitrogen-doped single vacancy graphene quantum dots (SV/3N) decorated with transition metals (TM = Mn, Co, Cu). We have studied the interactions between TM@SV/3N and four different target gases (AsH, NH, PH, and HS) through the computation of adsorption energies, charge transfer, noncovalent interaction, density of states, band gap, and work function for 12 distinct adsorption systems. Our comprehensive analysis included an in-depth assessment of sensors' stability, sensitivity, selectivity, and reusability for practical applications.
