Background: The purpose of this study was to investigate the suitability of nanostructured lipid carriers (NLCs) loaded with miltefosine (HePC) as an anticancer drug for the treatment of breast cancer.
Methods: HePC-NLCs were prepared using a microemulsion technique and then evaluated for particle size, polydispersity index (PDI), incorporation efficiency, in vitro release of entrapped drug, and hemolytic potential. Furthermore, pharmacokinetic, biodistribution, and liver toxicity analyses were performed in Sprague-Dawley rats, and antitumor efficacy was evaluated in Michigan Cancer Foundation-7 (MCF-7) and squamous cell carcinoma-7 (SCC-7) cells in vitro and in tumour-bearing BALB/c mice in vivo. Advanced analyses including survival rate, immunohistopathology, and terminal deoxynucleotidyl transferase dUTP nick end labelling (TUNEL) assays were performed to evaluate apoptosis in vivo.
Results: The average particle size of the HePC-NLCs was 143 ± 16 nm, with a narrow PDI (0.104 ± 0.002), and the incorporation efficiency was found to be 91 ± 7%. The NLCs released HePC in a sustained manner, and this release was significantly lower than that of free drug. The in vitro hemolytic assay demonstrated a significantly reduced hemolytic potential (~9%) of the NLCs compared to that of the test formulations. The HePC-NLCs demonstrated enhanced pharmacokinetic behaviour over free drug, including extended blood circulation and an abridged clearance rate in rats. Furthermore, the HePC-NLCs exhibited higher cytotoxicity than the free drug in MCF-7 and SCC-7 cells. Moreover, the HePC-NLCs showed significantly enhanced ( < 0.005) antitumor activity compared to that of the control and free drug-treated mouse groups. Tumour cell apoptosis was also confirmed, indicating the antitumor potential of the HePC-NLCs.
Conclusion: These findings demonstrate the ability of NLCs as a drug delivery system for enhanced pharmacokinetic, antitumor, and apoptotic effects, most importantly when loaded with HePC.

Background: Several chemical studies described the physiological efficacy of 1,4- dihydropyridines (DHPs). DHPs bind to specific sites on the α1 subunit of L-type calcium channels, where they demonstrate a more pronounced inhibition of Ca2+ influx in vascular smooth muscle compared to myocardial tissue. This selective inhibition is the basis for their preferential vasodilatory action on peripheral and coronary arteries, a characteristic that underlies their therapeutic utility in managing hypertension and angina.

Nevertheless, management remains inconsistent; corticosteroids are still frequently used. We analyzed the course of SJIA in children treated with anakinra according to the time of treatment initiation after disease onset.

Purpose: This systematic review aims to synthesize the current research on doping in combat sports, examining the prevalence, detection methods, prevention strategies, and overall impact on combat sports.
Design/methodology/approach: Of the 21 identified articles, six met the inclusion criteria. A systematic approach was used, including content analysis based on specific criteria: articles in English, original research, and relevance to sport and doping.

Introduction: Substance use disorders, particularly alcohol use disorders, represent a significant public health problem, with adolescents particularly vulnerable to their adverse effects. This study examined the possible anxiolytic and antidepressant effects of biotin, a crucial vitamin for brain function, in attenuating the behavioral and neurobiological changes associated with alcohol withdrawal in adolescent rats.
Materials And Methods: Sixty male Sprague-Dawley rats were exposed to a 20% ethanol solution for 21 days, followed by a 21-day drug-free period to assess long-term behavioral and physiological changes.
