A family-based behavioral group obesity randomized control feasibility trial across a clinical trials network: a focus on contact hours.
J Pediatr Psychol
January 2025
Psychiatry and Human Behavior, Warren Alpert Medical School of Brown University, Providence, RI, United States.
Objective: This ancillary study's purpose is to describe the relationship between dose of treatment and body mass index (BMI) outcomes in a tele-behavioral health program delivered in the IDeA States Pediatric Clinical Trials Network to children and their families living in rural communities.
Methods: Participants randomized to the intervention were able to receive 26 contact hours (15 hr of group sessions and 11 hr of individual sessions) of material focused on nutrition, physical activity, and behavioral caregiver training delivered via interactive televideo. Dose of the intervention received by child/caregiver dyads (n = 52) from rural areas was measured as contact hours.
Phase I Clinical Trial of High Doses of Seleno-L-methionine in Combination with Axitinib in Patients with Previously Treated Metastatic Clear Cell Renal Cell Carcinoma.
Clin Cancer Res
January 2025
Roswell Park Cancer Institute, Buffalo, NY, United States.
Background: Data in clear cell renal cell carcinoma (ccRCC) xenografts defined the seleno-L-methionine (SLM) dose and the plasma selenium concentrations associated with the enhancement of HIF1α/2α degradation, stabilization of tumor vasculature, enhanced drug delivery, and efficacy of axitinib. The data provided the rationale for the development of this phase I clinical trial of SLM and axitinib in advanced or metastatic relapsed ccRCC.
Patients And Methods: Patients were ≥18 years with histologically and radiologically confirmed advanced or metastatic ccRCC who had received at least one prior systemic therapy, which could include axitinib (last dose ≥6 months prior to enrollment).
Correcting a pathogenic mitochondrial DNA mutation by base editing in mice.

Graduate Program in Human Genetics, University of Miami Miller School of Medicine, 1501 NW 10th Avenue (M-860), Miami, FL 33136, USA.
Primary mitochondrial disorders are most often caused by deleterious mutations in the mitochondrial DNA (mtDNA). Here, we used a mitochondrial DddA-derived cytosine base editor (DdCBE) to introduce a compensatory edit in a mouse model that carries the pathological mutation in the mitochondrial transfer RNA (tRNA) alanine (mt-tRNA) gene. Because the original m.

Cypermethrin is a pyrethroid showing nephrotoxicity by generating ROS-impaired oxidative stress and changes in inflammatory and apoptotic markers. The harmful consequences are intended to be mitigated by the imbalance between oxidants and antioxidants. The anti-inflammatory and antioxidant possessions of nanocurcumin (NC) with improved bioavailability ameliorate Cyp toxicity in rat kidneys.

The CCl-induced hepatotoxicity model is a traditional preclinical assay applied to evaluate potential hepatoprotective compounds. However, several studies have used it with inappropriate dose and exposure time, generating both weak response or irreversible liver injury, as well as lack of representative liver and plasma biomarkers. Therefore, this study aims to determine the best dose and exposure time of CCl in Wistar rats, permitting a proper evaluation of potential hepatoprotective effect.
