T cell activation, proliferation, and differentiation are fundamentally driven by shifts in cellular metabolism, with mitochondria playing a central role. Cytochrome c oxidase (COX, complex IV) is a key player in this process, as its activity is crucial for apoptosis, mtDNA maintenance, mitochondrial transcription, and mitochondrial respiration (MR), all of which influence T cell fate and function. Despite its known roles, the specific functions of COX required for T cell activity in vivo remain unclear.

The complexity of macrophage (MΦ) plasticity and polarization states, which include classically activated pro-inflammatory (M1) and alternatively activated anti-inflammatory (M2) MΦ phenotypes, is becoming increasingly appreciated. Within the M2 MΦ polarization state, M2a, M2b, M2c, and M2d MΦ subcategories have been defined based on their expression of specific cell surface receptors, secreted cytokines, and specialized immune effector functions. The importance of immunometabolic networks in mediating the function and regulation of MΦ immune responses is also being increasingly recognized, although the exact mechanisms and extent of metabolic modulation of MΦ subtype phenotypes and functions remain incompletely understood.

Macrophages (MΦs) are prevalent innate immune cells, present throughout human bodily tissues where they orchestrate innate and adaptive immune responses to maintain cellular homeostasis. MΦs have the capacity to display a wide array of functional phenotypes due to different microenvironmental cues, particularly soluble bacterial secretory products. Recent evidence has emerged demonstrating that metabolism supports MΦ function and plasticity, in addition to energy and biomolecular precursor production.

BioOrthogonal Non-Canonical Amino acid Tagging (BONCAT) is a powerful tool for tracking protein synthesis on the level of single cells within communities and whole organisms. A basic premise of BONCAT is that the non-canonical amino acids (NCAA) used to track translational activity do not significantly alter cellular physiology. If the NCAA would induce changes in the metabolic state of cells, interpretation of BONCAT studies could be challenging.

Macrophages (MΦs) are phagocytic immune cells that are found in nearly all human tissues, where they modulate innate and adaptive immune responses, thereby maintaining cellular homeostasis. MΦs display a spectrum of functional phenotypes as a result of microenvironmental and stress-induced stimuli. Evidence has emerged demonstrating that metabolism is not only crucial for the generation of energy and biomolecular precursors, but also contributes to the function and plasticity of MΦs.

The taphylococcal espiratory egulator (SrrAB) modulates energy metabolism in Studies have suggested that regulated protein catabolism facilitates energy homeostasis. Regulated proteolysis in is achieved through protein complexes composed of a peptidase (ClpQ or ClpP) in association with an AAA family ATPase (typically, ClpC or ClpX). In the present report, we tested the hypothesis that SrrAB regulates a Clp complex to facilitate energy homeostasis in Strains deficient in one or more Clp complexes were attenuated for growth in the presence of puromycin, which causes enrichment of misfolded proteins.

Bald's eyesalve is an Anglo-Saxon medicinal remedy that has been used through ancient times to treat eye sty infections and may represent a source of ancientbiotics. This study assessed the efficacy of Bald's eyesalve against several strains of Staphylococcus aureus and Pseudomonas aeruginosa, including a multi-drug resistant phenotype, and identified the principal compound conveying antibacterial activity. Bald's eyesalve formulations were produced by combining garlic, onion or leek, wine, bovine bile, and brass, with specific ingredient omissions in several formulations, followed by incubation at 4 °C for 9 days.

Objective: Ecological niche modeling (ENM) has been used to assess how abiotic variables influence species distributions and diversity. Baboons are broadly distributed throughout Africa, yet the degree of climatic specialization is largely unexplored for individual taxa. Also, the influence of climate on baboon phylogenetic divergence is unknown.

Background: Metabolomics aims to characterize the metabolic phenotype and metabolic pathways utilized by microorganisms or other cellular systems. A crucial component to metabolomics research as it applies to microbial metabolism is the development of robust and reproducible methods for extraction of intracellular metabolites. The goal is to extract all metabolites in a non-biased and consistent manner; however, most methods used thus far are targeted to specific metabolite classes and use harsh conditions that may contribute to metabolite degradation.

Background: The aim of this study was to evaluate pediatric oncology providers' attitudes toward fertility preservation (FP), their use of educational materials, their approach to FP discussion, and their FP knowledge specifically pertaining to adolescent males.

Methods: A 40-item online survey was distributed to physicians, advanced practice nurses (APN), and nurses within pediatric oncology.

Results: About 78.

Objective: To report a single institutional experience with urethroplasty outcomes and success rates at long-term follow up.

Methods: A retrospective review was carried out of all urethroplasties performed by a single surgeon from 2000 to 2010. A total of 347 patients underwent urethroplasty during this time period, of which 227 had minimum 1-year follow-up data available.

Objective: To report the long-term outcomes of urethroplasty using abdominal wall skin (AWS) grafts. Men with long-segment strictures, prior urethroplasty, and lichen sclerosus (LS) pose challenges in surgical management, including the choice of graft tissue for urethral reconstruction. AWS grafts are an alternative when buccal mucosa or penile grafts are not feasible or chosen by the patient.

Objective: To determine the temporal relationship between vasectomy, varicocele, and hypogonadism diagnosis. Many young men undergo their first thorough genitourinary examination in their adult lives at the time of vasectomy consultation, providing a unique opportunity for diagnosis of asymptomatic varicoceles. Varicoceles have recently been implicated as a possible reversible contributor to hypogonadism.

Background Context: Previous publications have reported results with respect to functional outcome and sexual function in young women after traumatic injuries to the pelvis. It is well known that anterior spinal surgery has the possibility of causing reproductive dysfunction in men. Little has been described concerning deleterious effects of anterior spinal surgery in women of childbearing age.
