Fucoidan in Pharmaceutical Formulations: A Comprehensive Review for Smart Drug Delivery Systems

Fucoidan is a heterogeneous group of polysaccharides isolated from marine organisms, including brown algae and marine invertebrates. The physicochemical characteristics and potential bioactivities of fucoidan have attracted substantial interest in pharmaceutical industries in the past few decades. These polysaccharides are characterized by possessing sulfate ester groups that impart negatively charged surfaces, low/high molecular weight, and water solubility. In addition, various promising bioactivities have been reported, such as antitumor, immunomodulatory, and antiviral effects. Hence, the formulation of fucoidan has been investigated in the past few years in diverse pharmaceutical dosage forms to be able to reach their site of action effectively. Moreover, they can act as carriers for various drugs in value-added drug delivery systems. The current work highlights the attractive biopharmaceutical properties of fucoidan being formulated in oral, inhalable, topical, injectable, and other advanced formulations treating life-quality-affecting diseases. Therefore, the present work points out the current status of fucoidan pharmaceutical formulations for future research transferring their application from in vitro and in vivo studies to clinical application and market availability

Fabrication of TiO2/NiO p-n Nanocomposite for Enhancement Dye Photodegradation under Solar Radiation

A p-n nanocomposite based on TiO2 nanotubes (NTs) and NiO nanoparticles (NPs) was designed and optimized in this study to improve the photocatalytic performance of methylene blue (MB). The hydrothermal technique has been used to produce TiO2/NiO nanocomposites with different NiO NPs weight ratios; 1TiO2:1NiO, 1TiO2:2NiO, and 1TiO2:3NiO. The crystal phase, chemical composition, optical properties, and morphology of TiO2/NiO were explored by various techniques. TiO2 NTs have a monoclinic structure, while NiO NPs have a cubic structure, according to the structural study. The bandgap of TiO2 NTs was reduced from 3.54 eV to 2.69 eV after controlling the NiO NPs weight ratio. The TiO2/2NiO nanocomposite showed the best photodegradation efficiency. Within 45 min of solar light irradiation, the efficiency of MB dye degradation using TiO2/2NiO hits 99.5% versus 73% using pure TiO2 NTs. Furthermore, the catalytic photodegradation efficiency did not deteriorate significantly even after five reusability cycles, intimating the high stability of the TiO2/2NiO nanocomposite. This suggests that the loading of NiO NPs into TiO2 NTs lowers the recombination of photo-produced electron/hole pairs and enlarged solar spectral response range, which results in improved photocatalytic activity. The mechanism of charge transfer in the TiO2/NiO and kinetic models were discussed for the photodegradation of MB

Cell free DNA as a biomarker in medicolegal assessment in burn patients

Background: Burn victims have higher levels of cell free DNA (cfDNA), which allows its use as a direct indicator of cellular damage and burn vitality. Aim: Determination of cfDNA levels in burn patients and their correlation with total body surface area burned percent (TBSA%). Subjects and methods: Burn cases were evaluated to determine the prevalence of age and sex variations, period of admission, TBSA%, and the etiology and manner of burns. The plasma cfDNA concentration was measured within 24 hours of the burn injury in 40 burn cases and 20 control subjects. Results: The mean age of the cases was 34.38 years (median 33 years). Most patients were males (62.5%). Burning by flame or scalding represented 50% of the cases. Accidental burns were the most predominant. The mean of admission periods was 36.55 days while the mean value of TBSA% of the cases was 16.68%. There was a statistically significant difference in cfDNA values between cases and control subjects (p = 0.001). A positive correlation was found between cfDNA levels and TBSA% (r = 0.7; p < 0.001). Conclusion and recommendations: Levels of cfDNA were significantly different between burn cases and controls

Evaluating cognitive and affective abilities among medical students: behavioural and medicolegal perspectives

Medical students attending university for the first time experience a new environment, full of significant social, cultural, and intellectual challenges. Moreover, drug abuse and bullying among university students are major global concerns. The aim of the current study was to assess the impact of medicolegal issues on undergraduate and postgraduate students. It is a cross-sectional survey-based study, with each set of questions investigating cognitive functions, aggression, personality, and exposure to medicolegal issues. Males and those with a chronic disease have been significantly exposed to medicolegal issues; exposed students were significantly older than nonexposed ones. The scores of aggression were significantly higher among exposed and male students. The cognitive scores were higher for the students from rural areas than in urban areas, and females were more neurotic than males. The current study recommends conducting campaigns to educate university students on the importance of formally disclosing unethical behaviors and listening to the victims to facilitate overcoming their negative feelings. As many victims feel comfortable disclosing victimization to their friends, we recommend conducting peer educational programs to help friends support their colleagues regarding unethical misconduct

Use of Virtual Reality (VR) for medical training: Applications at different medical departments

Background: The rapid evolution of medical practice necessitates innovative training methods to keep pace with the demands of modern healthcare. Traditional education methods are increasingly complemented by simulation-based approaches, which provide practical and clinically relevant experiences. Virtual Reality (VR) has emerged as a significant tool in this realm, offering immersive, interactive training environments that aim to enhance learning outcomes. Aim: This paper explores the application of VR across various medical departments, including emergency medicine, health information management, nursing, and pharmacy. It examines VR's effectiveness in providing experiential learning, its advantages over traditional methods, and the challenges associated with its implementation. Methods: The study involves a comprehensive review of current literature and practical implementations of VR in medical training. It assesses the benefits and limitations of VR, evaluates evidence supporting its use, and discusses its applications in different medical fields. Key metrics include knowledge gain, cost efficiency, and user engagement. Results: VR offers distinct advantages such as immersive learning experiences, repeatable practice opportunities, and cost-effective simulation solutions. It simplifies access to clinical training, supports flexible learning schedules, and fosters engagement through gamification.&nbsp
