Combination strategies with PARP inhibitors in BRCA-mutated triple-negative breast cancer: overcoming resistance mechanisms.

Triple-negative breast cancer (TNBC) is a particularly aggressive breast cancer subtype, characterised by a higher incidence in younger women, rapid metastasis, and a generally poor prognosis. Patients with TNBC and BRCA mutations face additional therapeutic challenges due to the cancer's intrinsic resistance to conventional therapies. Poly (ADP-ribose) polymerase inhibitors (PARPis) have emerged as a promising targeted treatment for BRCA-mutated TNBC, exploiting vulnerabilities in the homologous recombination repair (HRR) pathway.

Enhancing Liver Transplant Outcomes through Liver Precooling to Mitigate Inflammatory Response and Protect Mitochondrial Function.

Transplanted organs experience several episodes of ischemia and ischemia-reperfusion. The graft injury resulting from ischemia-reperfusion (IRI) remains a significant obstacle to the successful survival of transplanted grafts. Temperature significantly influences cellular metabolic rates because biochemical reactions are highly sensitive to temperature changes.

Hemodynamic Renal Reserve Response in Conscious Normotensive and Hypertensive Mice.

Introduction: Renal function may be compromised following recovery from kidney insults. Renal functional reserve (RFR) is a measure of the difference between the kidney's maximum capacity and its baseline function, which helps identify any areas of the kidney with compromised function. Usually, RFR is evaluated using acute volume expansion (AVE), but this is typically done in anesthetized animals, which may not accurately represent the kidney's complete functional capacity.

A therapeutic antibody targeting annexin-A1 inhibits cancer cell growth in vitro and in vivo.

In this study we conducted the first investigation to assess the efficacy of a novel therapeutic antibody developed to target annexin-A1 (ANXA1). ANXA1 is an immunomodulatory protein which has been shown to be overexpressed in, and promote the development and progression of, several cancer types. In particular, high ANXA1 expression levels correlate with poorer overall survival in pancreatic and triple-negative breast cancers, two cancers with considerable unmet clinical need.

Symptomatic and Functional Outcomes Among Individuals at High Risk for Psychosis Participating in Step-Based Care.

Validated, multicomponent treatments designed to address symptoms and functioning of individuals at clinical high risk for psychosis are currently lacking. The authors report findings of a study with such individuals participating in step-based care-a program designed to provide low-intensity, non-psychosis-specific interventions and advancement to higher-intensity, psychosis-specific interventions only if an individual is not meeting criteria for a clinical response. Among individuals with symptomatic or functional concerns at enrollment, 67% met criteria for a symptomatic response (median time to response=11.
