Urology Department, Dorset County Hospital, Dorchester, UK.
Introduction: Prostate cancer (PCa) is the commonest urologic cancer worldwide and the leading cause of male cancer deaths in Nigeria. In Nigeria, orchidectomy remains the primary androgen deprivation therapy. Dihydrotestosterone (DHT) is the active prostatic androgen, but its relationship with PCa severity has not been extensively studied in Africa.

Objective: Metabolic reprogramming plays a critical role in modulating the innate and adaptive immune response, but its role in cutaneous autoimmune diseases, such as cutaneous lupus erythematosus (CLE), is less well studied. An improved understanding of the metabolic pathways dysregulated in CLE may lead to novel treatment options, biomarkers and insights into disease pathogenesis. The objective was to compare metabolomic profiles in the skin and sera of CLE and control patients using liquid chromatography-mass spectrometry (LC-MS).

Background: Dichloroacetate (DCA) has shown potential in modulating cellular metabolism and inflammation, particularly in cardiac conditions. This study investigates DCA's protective effects in a mouse model of myocardial infarction (MI), focusing on its ability to enhance cardiac function, reduce inflammation, and shift macrophage polarization from the pro-inflammatory M1 to the anti-inflammatory M2 phenotype.
Methods: An acute MI model was created using left anterior descending coronary artery ligation.

Objective: This study aimed to evaluate the effects of different cold acclimation strategies on exercise performance in male mice exposed to low-temperature environments.
Methods: Male mice were subjected to five distinct acclimation regimens over 8 weeks: immersion at 10 °C (10 °CI) or 20 °C (20 °CI), swimming at 10 °C (10 °CS), 20 °C (20 °CS), or 34 °C (34 °CS). During the first 2 weeks, the acclimation time progressively decreased from 30 min to 3 min per day, and the water temperatures were lowered from 34 °C to the target levels, followed by 6 weeks of consistent exposure.

The novel diiron amine complexes [FeCp(CO)(NHR')(μ-CO){μ-CN(Me)(Cy)}]CFSO [R' = H, 3; Cy, 4; CHCHNH, 5; CHCHNMe, 6; CHCH(4-CHOMe), 7; CHCH(4-CHOH), 8; Cp = η-CH, Cy = CH = cyclohexyl] were synthesized in 49-92 % yields from [FeCp(CO)(μ-CO){μ-CN(Me)(Cy)}]CFSO, 1a, using a straightforward two-step procedure. They were characterized by IR and multinuclear NMR spectroscopy, and the structure of 7 was confirmed through X-ray diffraction analysis. Complexes 3-8 and the acetonitrile adducts [FeCp(CO)(NCMe)(μ-CO){μ-CN(Me)(R)}]CFSO (R = Cy, 2a; Me, 2b; Xyl = 2,6-CHMe, 2c) were assessed for their water solubility, octanol-water partition coefficient and stability in physiological-like solutions.
