Isocaloric high-fat diet decreases motivation in the absence of obesity.

Objective: Obesogenic diets induce persistent changes in physical activity and motivation. It remains unclear whether these behavioral changes are driven by weight gain or exposure to obesogenic diets themselves. We investigated how exposure to a high-fat diet (HFD) in the absence of obesity affected physical activity, food motivation, and circadian patterns in mice.

Succinate receptor 1 signaling mutually depends on subcellular localization and cellular metabolism.

Succinate is a pivotal tricarboxylic acid cycle metabolite but also specifically activates the G- and G-coupled succinate receptor 1 (SUCNR1). Contradictory roles of succinate and succinate-SUCNR1 signaling include reports about its anti- or pro-inflammatory effects. The link between cellular metabolism and localization-dependent SUCNR1 signaling qualifies as a potential cause for the reported conflicts.

Distinct subcellular localization of tau and alpha-synuclein in lewy body disease.

Lewy bodies and neurofibrillary tangles, composed of α-synuclein (α-syn) and tau, respectively, often are found together in the same brain and correlate with worsening cognition. Human postmortem studies show colocalization of α-syn and tau occurs in Lewy bodies, but with limited effort to quantify colocalization. In this study, postmortem middle temporal gyrus tissue from decedents (n = 9) without temporal lobe disease (control) or with Lewy body disease (LBD) was immunofluorescently labeled with antibodies to phosphorylated α-syn (p-α-syn), tau phosphorylated at Ser202/Thr205 (p-tau), or exposure of tau's phosphatase-activating domain (PAD-tau) as a marker of early tau aggregates.

A perinatal psychiatry access program to address rural and medically underserved populations using telemedicine.

Background: Although highly prevalent, most perinatal mental health and substance use disorders often go unrecognized, undiagnosed, and untreated.

Completely Multipolar Model for Many-Body Water-Ion and Ion-Ion Interactions.

This work constructs an advanced force field, the Completely Multipolar Model (CMM), to quantitatively reproduce each term of an energy decomposition analysis (EDA) for aqueous solvated alkali metal cations and halide anions and their ion pairings. We find that all individual EDA terms remain well-approximated in the CMM for ion-water and ion-ion interactions, except for polarization, which shows errors due to the partial covalency of ion interactions near their equilibrium. We quantify the onset of the dative bonding regime by examining the change in molecular polarizability and Mayer bond indices as a function of distance, showing that partial covalency manifests by breaking the symmetry of atomic polarizabilities while strongly damping them at short-range.

In Utero Nano-Titanium Dioxide Exposure Results in Sexually Dimorphic Weight Gain and Cardiovascular Function in Offspring.

Engineered nanomaterials (ENM) are capable of crossing the placental barrier and accumulating in fetal tissue. Specifically, the ENM nano-titanium dioxide (nano-TiO), has been shown to accumulate in placental and fetal tissue, resulting in decreased birthweight in pups. Additionally, nano-TiO is an established cardiac toxicant and regulator of glucose homeostasis, and exposure in utero may lead to serious maladaptive responses in cardiac development and overall metabolism.

The Shu complex interacts with the replicative helicase to prevent mutations and aberrant recombination.

Homologous recombination (HR) is important for DNA damage tolerance during replication. The yeast Shu complex, a conserved homologous recombination factor, prevents replication-associated mutagenesis. Here we examine how yeast cells require the Shu complex for coping with MMS-induced lesions during DNA replication.

Targeting BRCA1-deficient PARP inhibitor-resistant cells with nickases reveals nick resection as a cancer vulnerability.

Tumors lacking the BRCA1 and BRCA2 (BRCA) hereditary breast cancer genes display heightened sensitivity to anti-cancer treatments, such as inhibitors of poly (ADP-ribose) polymerase 1 (PARP1). However, when resistance develops, treatments are lacking. Using CRISPR technology, we discovered that enhancing homologous recombination through increased DNA end resection in BRCA1-deficient cells by loss of the 53BP1-Shieldin complex-which is associated with resistance to PARP inhibitors-also heightens sensitivity to DNA nicks.
