Most Schistosoma mansoni infections are egg-negative after a single dose of oxamniquine. A cohort of 661 infected children was treated at 6-month intervals and assessed for nutritional and parasitological status. Initial biochemical and immunologic markers were measured in a subset of 84 children. All were treated at the start of therapy and at 6 months. Immunoglobulins only served as markers for active infection. No markers were predictive of cure or reinfection, except initial infection intensity and serum low-density lipoprotein. Ten percent were persistently infected and had no change in infection intensity at any time-point. Several factors suggest that this group was biologically different. In addition to failing to reduce their worm burden, they had significantly higher initial intensity of infection (100 versus 65 eggs/g, P = 0.001) and significantly lower initial serum low-density lipoprotein (72 versus 104 mg/dL, P = 0.045). The biologic plausibility of this observation is discussed.

Background: Environmental allergens induce the release of danger signals from the airway epithelium that trigger type 2 immune responses and promote airway inflammation.
Objective: To investigate the role of allergen-stimulated P2Y receptor activation in regulating ATP, IL-33 and DNA release by human bronchial epithelial (hBE) cells and mouse airways.
Methods: hBE cells were exposed to Alternaria alternata extract and secretion of ATP, IL-33 and DNA were studied in vitro.

Among the various causes of rhomboencephalitis, infection is the most common. However, conventional microbiological methods often yield negative results, making diagnosis challenging and leading to extensive, often inconclusive, diagnostics. Advanced molecular techniques like metagenomic next-generation sequencing (mNGS) offer a powerful and efficient approach to pathogen identification.

Chronic consequences of diabetes that are most commonly encountered are diabetic foot ulcers (DFUs), driven by microbiota-immune system dyshomeostasis, eventually leading to delayed wound healing. Available therapies, such as systemic or topical administration of anti-inflammatory or antimicrobial agents, are limited due to antibiotic resistance and immune dysfunction. Herein, a hybrid hydrogel dressing is developed as the artificial bioadhesive barrier at wound sites to maintain microbial and immunological homeostasis locally and have potent anti-inflammatory effects.

Phthalates are the emerging environmental toxicants derived from phthalic acid and its constituents, which are moderately present in plastics and many personal care products. Phthalate exposure occurs through various environmental factors, including air, water, and soil, with absorption facilitated via ingestion, inhalation, and dermal contact. Upon exposure, phthalates become bioavailable within the biological systems and undergo biotransformation and detoxification processes in the liver.

Background/objectives: The neurometabolic function is controlled by a complex multi-level physiological system that includes neurochemical, hormonal, immunological, sensory, and metabolic components. Functional disorders of monoamine systems are often detected in clinical practice together with metabolic dysfunctions. An important part of the mentioned pathological conditions are associated with disturbances in protein metabolism, some of the most important biomarkers which are aminotransferases and transcription factors that regulate and direct the most important metabolic reactions.
