The Role of Pharmacometrics in Advancing the Therapies for Autoimmune Diseases.

Autoimmune diseases (AIDs) are a group of disorders in which the immune system attacks the body's own tissues, leading to chronic inflammation and organ damage. These diseases are difficult to treat due to variability in drug PK among individuals, patient responses to treatment, and the side effects of long-term immunosuppressive therapies. In recent years, pharmacometrics has emerged as a critical tool in drug discovery and development (DDD) and precision medicine.

Cyclodextrin Inclusion Complexes with Hydrocortisone-Type Corticosteroids.

The hydrocortisone-type corticosteroid (HTC) group includes valuable active pharmaceutical ingredients (APIs) such as hydrocortisone, hydrocortisone acetate, cortisone acetate, tixocortol pivalate, prednisolone, methylprednisolone, and prednisone. Unfortunately, those APIs are characterized by low solubility, which hampers their application and reduces their therapeutic efficacy. The low polarity of HTC molecules allows them to form inclusion complexes with various cyclodextrins (CDs); however, as shown in this review, the type of applied CDs has a major impact on the final properties of the formed complex.

Log BB Prediction Models Using TLC and HPLC Retention Values as Protein Affinity Data.

However, there is limited knowledge regarding the efficacy of joining PLA/PHBV-based biocomposites modified with nanocrystalline cellulose (NCC) using vibration welding, which restricts their potential applications.

Analysis of the Impact of the Post-Consumer Film Waste Scenario and the Source of Electricity on the Harmfulness of the Mass Packaging Process.

Life cycle analysis (LCA) is a popular tool for determining the environmental impacts of a product in use. The aim of this study is to carry out a life cycle analysis, gate-to-gate, of a mass packaging process using a polyethylene shrinking film with a focus on energy consumption, raw material use and associated emissions, and film post-consumer disposal scenarios. Two different scenarios for the disposal of the shrinking film used in the packaging process were analyzed, namely recycling and landfills.

Multigenerational Consequences of Prenatal Exposure to Benzophenone-3 Demonstrate Sex- and Region-Dependent Neurotoxic and Pro-Apoptotic Effects in Mouse Brain.

Benzophenone-3 (BP-3), commonly used as a UV filter in personal care products and as a stabilizer, is an alleged endocrine disruptor with potential neurodevelopmental impacts. Despite its abundance in the environment, the studies on its effect on brain development are scarce, especially in terms of multigenerational impact. In this work, for the first time, we examined neurotoxic and pro-apoptotic effects of BP-3 on mouse brain regions (cerebral cortex and hippocampus) in both the first (F) and second (F) generations after maternal exposure to environmentally relevant BP-3 levels.

Assessing Environmental Risks of Local Contamination of Garden Urban Soils with Heavy Metals Using Ecotoxicological Tests.

Heavy metal soil contamination in urban areas poses a significant environmental hazard, particularly in regions with historical or ongoing industrial activities. These areas are often polluted with metals such as Pb, Cu, Cd, and Zn, which can be absorbed by plants and pose risks to both ecosystems and human health. This study investigates soil contamination in urban gardens in Wroclaw, Poland, where elevated levels of trace elements were detected.

Long-Term Follow-Up After Bariatric Surgery: Key to Successful Outcomes in Obesity Management.

: Bariatric surgery (BS) is considered one of the most effective interventions for the treatment of obesity. To achieve optimal long-term results, continuous follow-up (FU) within a multidisciplinary treatment team is essential to ensure patient compliance and maximize the benefits of BS. However, many patients find it difficult to maintain regular FU, which can affect the quality of care and lead to postoperative complications.

The Protective Role of Vitamin K in Aging and Age-Related Diseases.

Aging is an inevitable aspect of life, but age-related diseases are not an inseparable part of the aging process, and their risk can be reduced through a healthy lifestyle. Vitamin K has a broader impact than just blood clotting, and yet it remains overshadowed by other vitamins and underestimated by both doctors and consumers. Vitamin K (VK) is a multifunctional micronutrient with anti-inflammatory and antioxidant properties, whose deficiency may cause age-related diseases such as cardiovascular diseases, neurodegenerative diseases and osteoporosis.

Dietary Patterns, Serum BDNF and Fatty Acid Profiles in Physically Active Male Young Adults: A Cluster Analysis Study.

Although physical activity and balanced diet may increase peripheral brain-derived neurotrophic factor (BDNF) concentration, little is known about whether these factors modify BDNF content in physically active individuals and whether the serum fatty acid (FA) profile is related. This study aimed to evaluate quality of diet, identify specific dietary patterns and assess their influence on BDNF and FA levels in serum. It is hypothesized that there is a correlation between diet quality and the concentrations of BDNF and FA in the serum of physically active male individuals.
