Marontades pumilum is claimed to have beneficial effects in the treatment of diabetes mellitus (DM), however the underlying mechanisms were not fully identified. In this study, we hypothesized that M. pumilum could help to enhance cellular glucose uptake and reduces pancreatic complications, which contributed towards its beneficial effects in DM.
METHODS: Two parameters were measured (i) rate of glucose uptake by 3T3-L1 adipocyte cells in-vitro (ii) degree of pancreatic destruction in streptozotocin-nicotinamide induced male diabetic rats receiving M. pumilum aqueous extract (M.P) (250 and 500mg/kg/day) as reflected by levels of pancreatic oxidative stress, inflammation and apoptosis. In the meantime, phyto-chemical compounds in M.P were also identified by using LC-MS.
RESULTS: M.P was found able to enhance glucose uptake by 3T3-L1 adipocyte cells in-vitro while its administration to the male diabetic rats causes decreased in the fasting blood glucose (FBG), glycated haemoglobin (HbA1c), total cholesterol (TC), triglycerides (TG), low-density lipoprotein (LDL) levels but causes increased in insulin and high-density lipoprotein (HDL) levels, to near normal. Levels of oxidative stress in the pancreas as reflected by levels of lipid peroxidation product (LPO) decreased while levels of anti-oxidantive enzymes (SOD, CAT and GPx) in pancreas increased. Additionally, levels of inflammation as reflected by NF-κB p65, Ikkβ and TNF-α levels decreased while apoptosis levels as reflected by caspase-9 and Bax levels decreased. Anti-apoptosis marker, Bcl-2 levels in pancreas increased.
CONCLUSIONS: The ability of M.P to enhance glucose uptake and reduces pancreatic complications could account for its beneficial effects in treating DM.

PMID: 27261624 DOI: 10.1016/j.biopha.2016.04.032

INTRODUCTION: Protective effects of Vitis Vinifera seed aqueous extract (VVSAE) against pancreatic dysfunctions and elevation of oxidative stress, inflammation and apoptosis in the pancreas in diabetes were investigated. Histopathological changes in the pancreas were examined under light microscope.
METHODS: Blood and pancreas were collected from adult male diabetic rats receiving 28days treatment with VVSAE orally. Fasting blood glucose (FBG), glycated hemoglobin (HbA1c), insulin and lipid profile levels and activity levels of anti-oxidative enzymes (superoxide dismutase-SOD, catalase-CAT and glutathione peroxidase-GPx) in the pancreas were determined by biochemical assays. Histopathological changes in the pancreas were examined under light microscopy and levels of insulin, glucose transporter (GLUT)-2, tumor necrosis factor (TNF)-α, Ikkβ and caspase-3 mRNA and protein were analyzed by real-time PCR (qPCR) and immunohistochemistry respectively. Radical scavenging activity of VVSAE was evaluated by in-vitro anti-oxidant assay while gas chromatography-mass spectrometry (GC-MS) was used to identify the major compounds in the extract.
RESULTS: GC-MS analyses indicated the presence of compounds that might exert anti-oxidative, anti-inflammatory and anti-apoptosis effects. Near normal FBG, HbAIc, lipid profile and serum insulin levels with lesser signs of pancreatic destruction were observed following administration of VVSAE to diabetic rats. Higher insulin, GLUT-2, SOD, CAT and GPx levels but lower TNF-α, Ikkβ and caspase-3 levels were also observed in the pancreas of VVSAE-treated diabetic rats (p<0.05 compared to non-treated diabetic rats). The extract possesses high in-vitro radical scavenging activities.
CONCLUSION: In conclusions, administration of VVSAE to diabetic rats could help to protect the pancreas against oxidative stress, inflammation and apoptosis-induced damage while preserving pancreatic function near normal in diabetes.

Obesity has become a worldwide epidemic and its prevalence continues to increase at an alarming rate. It is considered a major risk factor for the development of several comorbidities, including type 2 diabetes, stroke, other cardiovascular diseases and even cancer. Conventional treatments for obesity, such as dietary interventions, exercise and pharmacotherapy, have proven to have limited effectiveness and are often associated with undesirable side effects. Therefore, there is a growing interest in exploring alternative therapeutic approaches. Nigella sativa (NS), a medicinal plant with multiple pharmacological properties, has gained attention due to its potential role in the treatment of obesity and its associated complications. The aim of this review is therefore to assess the effects of NS on obesity and its complications and to provide insights into the underlying mechanisms. From this review, NS appears to play a complementary or supportive role in the treatment of obesity and its complications. However, future studies are needed to verify the efficacy of NS in the treatment of obesity and its complications and to prove its safety so that it can be introduced in patients with obesity.

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.

INTRODUCTION: Noise-induced hearing loss (NIHL) is the second most common form of sensorineural hearing loss. It is one of the occupational health concerns worldwide with a prevalence rate of 16%. In Malaysia, there is an increasing trend of occupational NIHL prevalence encompassing agriculture, manufacturing, transportation, and construction sectors. The Malaysian Armed Forces (MAF) personnel, particularly the marine technicians of the Royal Malaysian Navy (RMN), have a heightened risk of developing NIHL due to prolonged exposure to hazardous noise levels onboard the military vessels. Previous studies involving MAF participants recorded a prevalence rate of approximately 22%. However, limited information is available regarding occupational NIHL among the RMN marine technicians. This study aimed to determine the prevalence of occupational NIHL and its associated factors among marine technicians working on the RMN vessels.
MATERIALS AND METHODS: A cross-sectional study was conducted among 127 randomly selected participants among marine technicians working on RMN vessels stationed at the Lumut Naval Base, Perak, Malaysia. The research instruments were questionnaires that contained information about sociodemographic, socioeconomic, occupational characteristics, and lifestyle behaviours, followed by a pure tone audiometric (PTA) assessment. Diagnosis of NIHL was made when the hearing threshold was ≥25 dB at 3 kHz to 6 kHz, with a recovery at 8 kHz on PTA.
RESULTS: The participants' median age was 32 years (interquartile range=27-37 years). The prevalence of occupational NIHL was 29.9% (95% CI=22.1-38.7). Factors associated with occupational NIHL on unadjusted regression analysis include age >30 years (OR=2.56, p=0.0185), middle household income (OR=2.76, p=0.0227), military rank especially the warrant officer (OR=7.12, p=0.0038), and length of service ≥15 years (OR=2.40, p=0.0246). After adjusting for ethnicity, smoking status, types of vessels, and participation in noise-related leisure activities, middle household income (OR=3.15, 95% CI=1.29- 7.87, p=0.0121) and warrant officer (OR=4.38, 95% CI=1.08- 20.52, p=0.0384) remained as significant predictors for occupational NIHL in this population.
CONCLUSION: In this study, the marine technicians working on board the RMN vessels had a higher prevalence of occupational NIHL compared to the prevalence among other MAF personnel as well as the global data. In addition, the probabilities of having occupational NIHL were significantly higher for middle-income technicians and those who ranked as warrant officers. These findings highlight the need for routine audiometric assessment and adoption of hearing conservation initiatives for individuals at high risk within this occupational cohort.

Eur J Pharmacol, 2016 Jan 15;771:173-90.
PMID: 26703866 DOI: 10.1016/j.ejphar.2015.12.028

Effect of Rhinacanthin C on hyperglycaemia, hyperlipidemia and pancreatic dysfunction in diabetes was investigated. In-vitro effect of Rhinacanthin C on glucose uptake was studied in 3T3-L1 cell line. Meanwhile, in-vivo effect of 28-days treatment with 5mg/kg/day or 20mg/kg/day Rhinacanthin C was studied in streptozotocin-nicotinamide induced male diabetic rats. Following completion of treatment, fasting blood glucose (FBG), HbA1c, insulin and lipid profile levels were measured by biochemical assays. Histopathological changes in pancreas were observed by light microscopy while levels of pancreatic oxidative stress were determined by enzymatic assays. Expression of insulin, TNFα, Ikkβ and caspase-3 in pancreas were quantified by immunohistochemistry. Molecular docking was used to identify interactions between Rhinacathin C with SOD or GPx enzymes. Dose-dependent increase in glucose uptake was observed with increasing doses of Rhinacathin C. Plasma FBG, HbA1c and lipid profile except LDL levels and pancreatic malonaldehyde level were reduced but serum insulin and pancreatic anti-oxidative enzymes (SOD, CAT and GPx) levels were increased in diabetic rats receiving Rhinacanthin C treatment. Decreased pancreatic histopathological changes with higher pancreatic insulin and Glut-2 levels but lower TNFα, Ikkβ and caspase-3 levels were observed in diabetic rats receiving Rhinacanthin C (P<0.05 compared to non-treated diabetic rats). In diabetic rats which received Rhinacathin C, changes in the above parameters did not achieve the value in non-diabetic rats. Docking shows Rhinacathin C possesses high degree interactions with SOD and GPx. By possessing these effects, Rhinacanthin C could be used as agent to alleviate pancreatic and other complications in diabetes.

This review aims to gather and summarize up-to-date information on the potential health benefits of Nigella sativa (NS) on diabetes mellitus (DM) and its complications from different animal models, clinical trials and in vitro studies. DM is one of the most prevalent metabolic disorders resulting from chronic hyperglycaemia due to problems in insulin secretion, insulin action or both. It affects people regardless of age, gender and race. The main consequence of DM development is the metabolic dysregulation of glucose homeostasis. Current treatments for DM include pharmacological therapy, insulin and diabetic therapy targeting β cells. Some of these therapeutic approaches are promising; however, their safety and effectiveness remain elusive. Since ancient times, medicinal plants have been used and proven effective against diseases. These plants are believed to be effective and benefit physiological and pathological processes, as they can be used to prevent, reduce or treat multiple diseases. Nigella sativa Linn. is an annual indigenous herbaceous plant belonging to Ranunculaceae, the buttercup family. NS exhibits multifactorial activities; it could ameliorate oxidative, inflammatory, apoptotic and insulinotropic effects and inhibit carbohydrate digestive enzymes. Thus, this review demonstrates the therapeutic potential of NS that could be used as a complement or adjuvant for the management of DM and its complications. However, future research should be able to replicate and fill in the gaps of the study conducted to introduce NS safely to patients with DM.

In this work, two low-cost wastes, bivalve shell (BS) and Zea mays L. husk leaf (ZHL), were investigated to adsorb malachite green (MG) from aqueous solutions. The ZHL was treated with calcined BS to give the BS-ZHL, and its ability to adsorb MG was compared with untreated ZHL, calcined BS and Ca(OH)(2)-treated ZHL under several different conditions: pH (2-8), adsorbent dosage (0.25-2.5 g L(-1)), contact time (10-30 min), initial MG concentration (10-200 mg L(-1)) and temperature (303-323 K). The equilibrium studies indicated that the experimental data were in agreement with the Langmuir isotherm model. The use of 2.5 g L(-1) BS-ZHL resulted in the nearly complete removal of 200 mg L(-1) of MG with a maximum adsorption capacity of 81.5 mg g(-1) after 30 min of contact time at pH 6 and 323 K. The results indicated that the BS-ZHL can be used to effectively remove MG from aqueous media.

In this study, calcined Lapindo volcanic mud (LVM) was used as an adsorbent to remove an anionic dye, methyl orange (MO), from an aqueous solution by the batch adsorption technique. Various conditions were evaluated, including initial dye concentration, adsorbent dosage, contact time, solution pH, and temperature. The adsorption kinetics and equilibrium isotherms of the LVM were studied using pseudo-first-order and -second-order kinetic equations, as well as the Freundlich and Langmuir models. The experimental data obtained with LVM fits best to the Langmuir isotherm model and exhibited a maximum adsorption capacity (q(max)) of 333.3 mg g(-1); the data followed the second-order equation. The intraparticle diffusion studies revealed that the adsorption rates were not controlled only by the diffusion step. The thermodynamic parameters, such as the changes in enthalpy, entropy, and Gibbs free energy, showed that the adsorption is endothermic, random and spontaneous at high temperature. The results indicate that LVM adsorbs MO efficiently and could be utilized as a low-cost alternative adsorbent for the removal of anionic dyes in wastewater treatment.
