Spheroid cultures of primary human hepatocytes (PHH) are used in studies of hepatic drug metabolism and toxicity. The cultures are maintained under different conditions, with possible confounding results. We performed an in-depth analysis of the influence of various culture conditions to find the optimal conditions for the maintenance of an like phenotype. The formation, protein expression, and function of PHH spheroids were followed for three weeks in a high-throughput 384-well format. Medium composition affected spheroid histology, global proteome profile, drug metabolism and drug-induced toxicity. No epithelial-mesenchymal transition was observed. Media with fasting glucose and insulin levels gave spheroids with phenotypes closest to normal PHH. The most expensive medium resulted in PHH features most divergent from that of native PHH. Our results provide a protocol for culture of healthy PHH with maintained function - a prerequisite for studies of hepatocyte homeostasis and more reproducible hepatocyte research.

BackgroundTherapeutic plasma exchange (TPE) with albumin replacement has emerged as a potential treatment for Alzheimer's disease (AD). The AMBAR trial showed that TPE could slow cognitive and functional decline, along with changes in core and inflammatory biomarkers in cerebrospinal fluid.ObjectiveTo evaluate the safety and effectiveness of TPE in a real-world setting in Argentina.

Background: Metabolic reprogramming is an important hallmark of cervical cancer (CC), and extensive studies have provided important information for translational and clinical oncology. Here we sought to determine metabolic association with molecular aberrations, telomere maintenance and outcomes in CC.
Methods: RNA sequencing data from TCGA cohort of CC was analyzed for their metabolic gene expression profile and consensus clustering was then performed to classify tumors into different groups/subtypes.

Immunoglobulin A nephropathy (IgAN), the most prevalent primary glomerulonephritis globally, is characterized by mesangial IgA deposition and heterogeneous clinical trajectories. Historically, management relied on renin-angiotensin system inhibition and empirical immunosuppression, yet high lifetime kidney failure risk persists despite optimized care. This review synthesizes advances in molecular pathogenesis, highlighting how the traditional multi-hit hypothesis-while foundational for targeted therapy development-fails to capture IgAN's recurrent, self-amplifying nature.

Asthma is one of the most prevalent chronic respiratory illnesses, significantly impacting patients through shortness of breath and even death. Acute exacerbations are usually controlled with a short-acting beta agonist, such as an albuterol inhaler, as well as long-acting agents to prevent the occurrence of exacerbations and status asthmaticus. Status asthmaticus is an emergent episode of asthma that is refractory to standard treatment.

Multiple myeloma (MM) is an incurable blood cancer characterized by clonal bone marrow plasmacytosis, hypercalcemia, renal failure, anemia, and osteolytic bone disease. Approximately 20% of NDMM patients, not predicted to have high-risk disease at diagnosis, progress early, despite optimal induction +/- ASCT and lenalidomide maintenance, and are subsequently categorized as functional high-risk (FHR) disease. Standardized risk-stratification models incorporate biomarkers of tumor burden, existence of high-risk cytogenetics, with the presence/absence of plasma cell leukemia/extramedullary disease to attribute high-risk at diagnosis; however, depth/duration of response to novel agent-based induction (NA-IND) as dynamic markers of disease risk have not been defined.
