Interactive and unimodal relationships between plant biomass, abiotic factors, and plant diversity in global grasslands.

Grasslands cover approximately a third of the Earth's land surface and account for about a third of terrestrial carbon storage. Yet, we lack strong predictive models of grassland plant biomass, the primary source of carbon in grasslands. This lack of predictive ability may arise from the assumption of linear relationships between plant biomass and the environment and an underestimation of interactions of environmental variables.

Neoadjuvant nivolumab and chemotherapy in early estrogen receptor-positive breast cancer: a randomized phase 3 trial.

Patients with estrogen receptor-positive (ER+), human epidermal growth factor receptor 2-negative (HER2-) primary breast cancer (BC) have low pathological complete response (pCR) rates with neoadjuvant chemotherapy. A subset of ER+/HER2- BC contains dense lymphocytic infiltration. We hypothesized that addition of an anti-programmed death 1 agent may increase pCR rates in this BC subtype.

Pembrolizumab and chemotherapy in high-risk, early-stage, ER/HER2 breast cancer: a randomized phase 3 trial.

Addition of pembrolizumab to neoadjuvant chemotherapy followed by adjuvant pembrolizumab improved outcomes in patients with high-risk, early-stage, triple-negative breast cancer. However, whether the addition of neoadjuvant pembrolizumab to chemotherapy would improve outcomes in high-risk, early-stage, estrogen receptor-positive/human epidermal growth factor receptor 2-negative (ER/HER2) breast cancer remains unclear. We conducted a double-blind, placebo-controlled phase 3 study (KEYNOTE-756) in which patients with previously untreated ER/HER2 grade 3 high-risk invasive breast cancer (T1c-2 (≥2 cm), cN1-2 or T3-4, cN0-2) were randomly assigned (1:1) to neoadjuvant pembrolizumab 200 mg or placebo Q3W given with paclitaxel QW for 12 weeks, followed by four cycles of doxorubicin or epirubicin plus cyclophosphamide Q2W or Q3W.

Intermittent documentation of blood pressure values does not provide comprehensive evaluation of the hemodynamic response during continuous intravenous medication administration.

Blood pressure (BP) is a dynamic measure that is frequently discussed in static terms. There exist many limitations in current documentation systems whereby documented BP values may not be reflective of the dynamic variability of BP. This study used an observational, prospective, non-randomized study design to examine the variability in BP response during intravenous vasoactive medication administration in an intensive care unit setting.

Humanized dual-targeting antibody-drug conjugates specific to MET and RON receptors as a pharmaceutical strategy for the treatment of cancers exhibiting phenotypic heterogeneity.

Cancer heterogeneity, characterized by diverse populations of tumorigenic cells, involves the occurrence of differential phenotypes with variable expressions of receptor tyrosine kinases. Aberrant expressions of mesenchymal-epithelial transition (MET) and recepteur d'origine nantais (RON) receptors contribute to the phenotypic heterogeneity of cancer cells, which poses a major therapeutic challenge. This study aims to develop a dual-targeting antibody-drug conjugate (ADC) that can act against both MET and RON for treating cancers with high phenotypic heterogeneity.

The association of origin and environmental conditions with performance in professional IRONMAN triathletes.

We have (i) little knowledge about where the fastest professional IRONMAN triathletes originate from and where the fastest races take place and (ii) we have no knowledge of the optimal weather conditions for an IRONMAN triathlon. The aims of the present study were, therefore, (i) to investigate the origin and the fastest IRONMAN race courses for professional triathletes and (ii) to evaluate the best environmental conditions (i.e.

Measurements of groundwater, hydrodynamics, and sand characteristics at a dissipative sea turtle nesting beach.

Beach groundwater and nearshore hydrodynamic data were collected during a field experiment along two dissipative beach transects on Galveston Island, Texas, in the fall of 2023. The monitored beaches serve as nesting habitat for the critically endangered Kemp's ridley sea turtle. Conditions ranged from calm to stormy, with two storms occurring during the experiment, inundating the entire beach up to the dune toe.

GnIH secreted by green light exposure, regulates bone mass through the activation of Gpr147.

Reproductive hormones associated with the hypothalamic-pituitary-gonadal (HPG) axis are closely linked to bone homeostasis. In this study, we demonstrate that Gonadotropin inhibitory hormone (GnIH, one of the key reproductive hormones upstream of the HPG axis) plays an indispensable role in regulating bone homeostasis and maintaining bone mass. We find that deficiency of GnIH or its receptor Gpr147 leads to a significant reduction in bone mineral density (BMD) in mice primarily by enhancement of osteoclast activation in vivo and in vitro.

TRAF2 and RIPK1 redundantly mediate classical NFκB signaling by TNFR1 and CD95-type death receptors.

This study suggests a modified model of TNFR1-induced complex I-mediated NFκB signaling. Evaluation of a panel of five tumor cell lines (HCT116-PIK3CAmut, SK-MEL-23, HeLa-RIPK3, HT29, D10) with TRAF2 knockout revealed in two cell lines (HT29, HeLa-RIPK3) a sensitizing effect for death receptor-induced necroptosis and in one cell line (D10) a mild sensitization for TNFR1-induced apoptosis. TRAF2 deficiency inhibited death receptor-induced classical NFκB-mediated production of IL-8 only in a subset of cell lines and only partly.

Dyad leadership blueprint: nine strategies for effective collaboration.

Background/aim: The physician-administrator dyads are a strategic method of collaboration in healthcare organisations. Dyad leaders are part of a multidisciplinary team that integrates their expertise to generate better patient, physician, and organisational outcomes. An assumption of team science is that diverse experts, while knowledgeable, struggle to work together to resolve problems because of their vastly different decision-making and implementation strategies.

Exploring Mixed Reality for Patient Education in Cerebral Angiograms: A Pilot Study.

Background: Cerebral aneurysms (CAs) affect 3-5% of the general population, with saccular aneurysms being the most common type. Despite advances in treatment, patient understanding of CAs and associated procedures remains limited, impacting informed consent and treatment outcomes.

Objectives: This pilot study aims to evaluate the effectiveness of mixed reality (MR) technology in enhancing patient education and understanding of cerebral angiograms and aneurysm treatment, thereby improving the patient-surgeon communication process.

Vagus nerve stimulation rescues impaired fear extinction and social interaction in a rat model of autism spectrum disorder.

Clinical diagnosis of anxiety disorders is highly prevalent in autism spectrum disorders (ASD). Available treatments for anxiety offer limited efficacy in the ASD population. Vagus nerve stimulation (VNS) has an anxiolytic effect in rats and, when coupled with fear extinction training, VNS enhances extinction of fear in healthy rats.

Low socioeconomic status adversely affects outcomes after coronary artery bypass grafting.

Objectives: Although socioeconomic status (SES) is believed to affect patient outcomes after coronary artery bypass grafting (CABG), readmission data are sparse. In a national cohort, we analyzed the influence of SES on readmission, resource utilization, and mortality after CABG.

Methods: We queried the Nationwide Readmissions Database to identify patients who underwent isolated CABG from January 2016 through December 2018.
