The advancement in nanotechnology is the trigger for exploring the synthesis of selenium nanoparticles and their use in biomedicine. Therefore, this study aims to synthesize selenium nanoparticles using M. oleifera as a reducing agent and evaluate their antioxidant and antidiabetic potential. Our result demonstrated a change in the color of the mixture from yellow to red, and UV-Vis spectrometry of the suspension solution confirmed the formation of MO-SeNPs with a single absorbance peak in the range of 240–560 nm wavelength. FTIR analysis revealed several bioactive compounds, such as phenols and amines, that could possibly be responsible for the reduction and stabilization of the MO-SeNPs. FESEM + EDX analysis revealed that the amorphous MO-SeNPs are of high purity, have a spherical shape, and have a size of 20–250 nm in diameter, as determined by HRTEM. MO-SeNPs also exhibit the highest DPPH scavenging activity of 84% at 1000 μg/mL with an IC50 of 454.1 μg/mL and noteworthy reducing ability by reducing power assay. Furthermore, MO-SeNPs showed promising antidiabetic properties with dose-dependent inhibition of α-amylase (26.7% to 44.53%) and α-glucosidase enzyme (4.73% to 19.26%). Hence, these results demonstrated that M. oleifera plant extract possesses the potential to reduce selenium ions to SeNPs under optimized conditions with notable antioxidant and antidiabetic activities.

2-phenylchromen-4-one, commonly known as flavone, plays multifaceted roles in biological response that can be abundantly present in natural sources. The methoxy group in naturally occurring flavones promotes cytotoxic activity in various cancer cell lines by targeting protein markers, in facilitating ligand–protein binding mechanisms and activating cascading downstream signaling pathways leading to cell death. However, the lipophilic nature of these analogs is a key concern as it impacts drug membrane transfer. While lipophilicity is crucial for drug efficacy, the excessive lipophilic effects in flavonoids can reduce water solubility and hinder drug transport to target sites. Recent in vitro studies suggest that the incorporation of polar hydroxyl groups which can form hydrogen bonds and stabilize free radicals may help overcome the challenges associated with methoxy groups while maintaining their essential lipophilic properties. Naturally coexisting with methoxyflavones, this review explores the synergistic role of hydroxy and methoxy moieties through hydrogen bonding capacity in maximizing cytotoxicity against cancer cell lines. The physicochemical analysis revealed the potential intramolecular interaction and favorable electron delocalization region between both moieties to improve cytotoxicity levels. Together, the analysis provides a useful strategy for the structure–activity relationship (SAR) of flavonoid analogs in distinct protein markers, suggesting optimal functional group positioning to achieve balanced lipophilicity, effective hydrogen bonding, and simultaneously minimized steric hindrance in targeting specific cancer cell types.

Ranked as the second leading cause of death and the primary factor to adult disability worldwide, stroke has become a global epidemic problem and burden. As a developing country, Malaysia still faces challenges in providing ideal rehabilitation services to individuals with physical disabilities including stroke survivors. Conventional post-stroke care is often delivered in a team- based approach and involves several disciplines, such as physical therapy, occupational therapy, speech and language therapy, depending on the nature and severity of the deficits. Robots are potential tools for stroke rehabilitation as they can enhance existing conventional therapy by delivering a precise and consistent therapy of highly repetitive movements. In addition, robot- assisted therapy could facilitate the effectiveness of unsupervised rehabilitation and thus, may reduce the cost and duration of therapist-assisted rehabilitation. Research on robot-assisted physiotherapy for stroke in Malaysia is slowly coming into the limelight in the past two decades. This review explores the effectiveness of robot-assisted physiotherapy particularly in improving motor functions of stroke survivors in Malaysia.

Background: As the third leading cause of mortality in Malaysia, stroke is recognised as a medical emergency which requires urgent medical attention within a limited timeframe to prevent exacerbation of the brain damage and death in patients. Recent report revealed a high prevalence of pre-hospital delay amongst the stroke patients due to the lack of awareness on symptoms and risk factors of stroke, as well as poor understanding on appropriate action towards stroke. A number of studies had assessed stroke awareness amongst urban population residing in central region of Malaysia but yet amongst rural population. Methods: A cross-sectional survey was conducted amongst individuals residing in rural districts of Selangor by using a set of questionnaires assessing the sociodemographic characteristics, as well as the awareness and action towards stroke symptoms and risk factors. Results: All 343 respondents were able to recognise at least one modifiable risk factor for stroke. Meanwhile, only 36.44% were able to identify all the stroke symptoms. Despite majority of them were familiar with the stroke term, less than half of the respondents were aware of calling the emergency medical service as the appropriate action towards stroke symptoms. Conclusion: The present study indicated a poor level of awareness and action towards stroke symptoms and risk factors amongst rural population residing in Selangor.

Background The search for efficient treatments for type 2 diabetes mellitus (T2DM) has highlighted the potential of plant-based therapeutic compounds and eco-friendly processes for producing selenium nanoparticles. This study investigates the antidiabetic potential of Moringa oleifera-mediated biogenic selenium nanoparticles (MO-SeNPs) in diabetic rats. Methods Male Sprague-Dawley rats were induced with diabetes via a high-fat diet for 2 weeks followed by a single intraperitoneal injection of streptozotocin (STZ) at 45 mg/kg body weight (BW). The rats were divided into five groups: normal, diabetic control, metformin at 100 mg/kg/BW, and two groups treated with oral administration of MO-SeNPs at 0.25 and 0.5 mg/kg body weight for 28 days. Food and water intake as well as fasting blood glucose and body weight were measured weekly. After the treatment period, rats were sacrificed, and blood and liver samples were harvested for further analysis. Results MO-SeNPs treatment significantly reduced blood glucose levels (p < 0.05) and restored insulin resistance, with lower dose demonstrating better glycaemic control than larger dose. MO-SeNPs also increased hepatic antioxidant enzyme activity, including GSH-Px, CAT, and T-SOD, which neutralise oxidative stress. MO-SeNPs also improves cardiovascular health by raising HDL and lowering LDL. MO-SeNPs showed hepatoprotective benefits by lowering inflammatory markers such TNF-α, IL-6, IL-1β, iNOS, and AGEs, and reduced lipid peroxidation. Diabetes raises inflammatory indicators, causing liver damage and other problems. The reduction in these indicators shows MO-SeNPs reduce liver inflammation and protect the liver. The normalisation of liver enzyme levels (ALT, AST, ALP) showed improved liver function. Conclusions The findings suggest that the green synthesis of SeNPs using Moringa oleifera offers a viable alternative for diabetes treatment, highlighting its potential to enhance glycemic control and improve overall metabolic health.

Hypoxia-inducible factor prolyl hydroxylase (HIF-PHD) inhibitors, clinically established for treating renal anemia, are emerging as potent immunomodulators with therapeutic potential far beyond erythropoiesis. This review dissects the mechanistic basis of their action, centered on the stabilization of hypoxia-inducible factor-alpha (HIF-α), a master transcription factor that orchestrates fundamental shifts in immune cell function. We synthesize evidence showing how HIF-α stabilization alters innate immunity, recalibrates T- and B-cell responses, and reshapes inflammatory signaling. This activity translates to significant efficacy in preclinical models of autoimmune disorders, organ fibrosis, and ischemia–reperfusion injury. However, their broader clinical translation is hindered by a critical paradox in oncology. While HIF-α can potentiate anti-tumor immunity, its sustained activation risks promoting malignancy by driving angiogenesis, metabolic reprogramming, and fostering an immunosuppressive tumor microenvironment. Addressing this duality, alongside the potential for long-term immune dysregulation, is paramount. Future development must therefore prioritize precision-targeting strategies to harness the therapeutic benefits of HIF-PHD inhibitors while mitigating their pro-tumorigenic liabilities.
