    Introduction: Dyslipidaemia is one of the risk factors contributing to the pathogenesis of cardiovascular
    diseases (CVDs). This study was conducted to investigate the effect of wet cupping on lipid profile.

    Methods: This randomized controlled trial was conducted in 2012 at the School of Medical Sciences,
    Universiti Sains Malaysia, Malaysia. Sixty-two healthy volunteers ranging from 30 to 60 years old were
    randomized into control and intervention groups. Subjects in the intervention group were assigned to two
    sessions of wet cupping at the beginning of the study and at the third month; individuals in the control group
    did not undergo any cupping procedure. Venous blood sample was collected for serum lipid profile: Total
    Cholesterol (TC), High Density Lipoprotein Cholesterol (HDL-C), Low Density Lipoprotein Cholesterol (LDL-C),
    and triglycerides; measured at baseline, first, third and fourth month.

    Results: Subjects in the cupping
    group had significant improvements from baseline to third and fourth month for TC (MD=-0.56, P=0.004),
    HDL-C (MD=-0.22, P

    Canine mammary gland tumor (CMT) is the most common tumor in intact female dog. Zerumbone (ZER) has promising anticancer properties, but plagued with poor water solubility, poor absorption, bioavailability, and delivery to target tissues. To solubilize, ZER was loaded into nanostructured lipid carrier (NLC) to produce ZER-loaded NLC (ZER-NLC). The objectives of this study were to determine the antiproliferative effect and the mode of cell death induced by ZER-NLC and ZER on a canine mammary gland tumor (CMT) adenocarcinoma primary cell line. There was no significant difference (p>0.05) between ZER-NLC and ZER treatments in the inhibition of CMT cell proliferation; thus, the loading of ZER into NLC did not compromise the cytotoxic effect of ZER. Microscopically, ZER-NLC- and ZER-treated CMT cells showed apoptotic cell morphology. ZER-NLC and ZER treatments significantly downregulated the antiapoptotic Bcl-2 and upregulated the proapoptotic Bax gene expressions in CMT cells. Both ZER-NLC and ZER-treated CMT cells showed significant (p<0.0001) increases in caspase-8, -9, and -3/7 protein activities. In conclusion, ZER-NLC induced CMT cell death via regulation of Bcl-2 and Bax gene expressions and caspase activations, indicating the involvement of both the intrinsic and extrinsic pathways of apoptosis. This study provided evidences for the potential of ZER-NLC as an anticanine mammary gland adenocarcinoma chemotherapy.

    Microalgae biorefinery is presently receiving a lot of attention as driven by its production of high value-added products. In this study, an oleaginous microalga Aurantiochytrium limacinum SR21 was cultured for docosahexaenoic acid (DHA) production using 20% (w/v) of K2HPO4-waste feedstock to replace 0.005% (w/v) of KH2PO4 in the flask culture. DHA is an essential nutrient for human's brain functionalities. Collectively, the K2HPO4-waste feedstock with working concentration of 0.005% (w/v) in the cultivation prompted a higher lipid content (8.29%) and DHA production (128.81 mg.L-1). Moreover, natural plant pigment products containing stabilised betacyanins were utilised as natural red colourants for hard candy production. This study develops microalgal cultivation using salt-rich waste feedstock for a higher lipid and DHA content as well as application of natural colouring agents in food products.

    Filamentous fungi such as Fusarium equiseti KR706303 and Penicillium citrinum KR706304
    are capable of sequestering heavy metals from aqueous solutions. In the present study, the role
    play by various functional groups present in the cell wall of F. equiseti KR706303 and P.
    citrinum KR706304 during lead and copper ions biosorption was investigated. The fungal
    biomass was chemically treated to modify the functional groups present in their cell wall. These
    modifications were studied through biosorption experiments. It was found that an esterification
    of the carboxyl and phosphate groups, methylation of the amine groups and extraction of lipids
    significantly decrease the biosorption of both lead and copper ions studied. Therefore, the
    carbonyl, hydroxyl and amide groups were recognized as important in the biosorption of metal
    ions by the tested fungi. The study showed that there was no release of any metal ions from the
    biomass after biosorption, indicating that ion exchange may not be a key mechanism in the
    biosorption of lead and copper ions by these fungi but complexation of metal ions within the
    fungal cell wall.

    Slaughtering is the first step in meat processing. It involves killing an animal for the production of meat. Effectiveness of slaughter is determined by the amount of blood removed from the animal. This study aimed to compare the chemical changes and microbiological quality of broiler chicken meat slaughtered by Halal and Non-Halal slaughter methods during refrigerated storage. A total of sixty (60) broiler chickens were slaughtered by: i) Neck cutting (NC) - by severing the jugular veins, carotid arteries, trachea and the oesophagus according to the Islamic ritual method of slaughter and (ii) Neck poking (NP) - by poking the neck of the bird with a sharp object. Residual blood was quantified by measuring the haem iron content in the breast meat samples. Storage stability of chicken meat was evaluated by measuring the extent of lipid oxidation determined by thiobarbituric acid reactive substances (TBARS) and by assessing the microbiological quality of the meat. Haem iron content decreased significantly (P0.05) on chicken meat lipid oxidation at 1, 3, and 9 day of storage at 4oC. However, at 5 and 7 day of storage, significant differences (P

    BACKGROUND: Anu Tailam, an Ayurvedic medicated oil where 'anu' meant for atom and 'tailam' meant for oil and virtually meant for 'oil of subtle or atomic size particles'. Since the major active ingredients in this formulation are incorporated from the polyherbal decoction, it is expected to contain predominantly water soluble ingredients.

    OBJECTIVES: It is hypothesized that these polar active botanical ingredients are present in the formulation should be either suspended in the form of submicron particles or entrapped in the submicron vesicular structures since the formulation did not show any precipitation or phase separation instead showed a monophasic oily liquid with very little moisture.

    MATERIALS AND METHODS: In the present investigation, the micro architecture of the anu tailam is studied via column chromatography and high performance thin layer chromatography to prove the contents are polar hydrophilic compounds followed by optical microscopy, photon correlation Spectroscopy (PCS) and environmental scanning electron microscope (ESEM) to study the particle/vesicle size of the formulation.

    RESULTS: In this study, it was proved that the formulation contained only polar ingredients and can be extracted in polar solvents like methanol and ethanol. It was also found that the formulation taken for study contained nano particles of the active botanical ingredients embedded in a network of vesicular structures of the lipid base.

    CONCLUSION: The selected Ayurvedic formulation 'anutailam' found to contain novel nano drug delivery system to deliver water soluble ingredients across barriers.

    Long term environmental problems of non-biodegradable plastic, the need to conserve finite fossil fuels and the impact of globalization of food supply are some of the driving forces in looking towards biodegradable plastics as an alternative to the existing petrochemical-based polymers for food packaging application. The stability of nutritional composition, lipid oxidation, physical traits of beef patties packed with different types of plastics and the surface morphology of plastics after 3 months of frozen storage (-18 were studied. Beef patties were packed with either non-biodegradable high density polyethylene (PE), hydro-biodegradable low density polyethylene/ thermoplastic sago starch plastic (PEs), hydro-biodegradable polylactic acid plastic (PIA) or oxo-biodegradable plastic (oxo)). There were no differences in most of the nutrients analyzed and lipid oxidation values of beef patties packed with either biodegradable or non-biodegradable plastics after storage. There were significant (p decreased in fat for cooked patties and moisture for both raw and cooked patties. Lipid oxidation indices of beef patties increased after storage but they were not significant (p Beef patties packed with biodegradable packaging materials were able to retain moisture without jeopardizing the diameter reduction during storage. In summary, the application of biodegradable plastics for packing beef patties was considered acceptable and can be suggested as an alternative packaging item to replace conventional polyethylene plastic packaging.

    Background: Metabolic syndrome (MetS), which consists of cluster of conditions, hypertension, hyperlipidemia, hyperglycemia, and visceral obesity, is affecting population worldwide. Studies have shown that plant derived flavonoids have the ability to alleviate MetS. Naringin is a type of glycoside flavonoid found in most plant and it plays a critical role in the treatment of MetS due to its antioxidant activity and ability to regulate cytokines.

    Methods: A systematic review was done to study the effects of naringin on the metabolic diseases using electronic databases which include Ovid and Scopus using specific descriptors published from the year 2010 till present to provide updated literature on this field. The articles were assessed and chosen based on the criteria in which the mechanisms and effects of naringin on different metabolic diseases were reported.

    Results: Thirty-four articles were identified which referred to the studies that correspond to the previously stated criteria. Subsequently after screening for the articles that were published after the year 2010, finally, 19 articles were selected and assessed accordingly. Based on the assessment, naringin could alleviate MetS by reducing visceral obesity, blood glucose, blood pressure, and lipid profile and regulating cytokines.

    Conclusions: Naringin is an antioxidant that appears to be efficacious in alleviating MetS by preventing oxidative damage and proinflammatory cytokine release. However, the dosage used in animal studies might not be achieved in human trials. Thus, adequate investigation needs to be conducted to confirm naringin's effects on humans.

    Currently, oxidative stress (OS) has become a major interest in point of basic science and clinical research. The imbalance between generations and clearances of oxidants leads to OS. Oxidants are mainly composed of reactive oxygen species (ROS) and reactive nitrogen species (RNS) which are manifested as oxidized macromolecules causing deleterious effects in several organs. Lipid, protein and DNA oxidation products can provide extensively approach of potential oxidative stress biomarkers. OS leads to the fundamental cellular and tissue damages and consequence effect to various organs or systems. This review emphasizes the systemic pathology induced by OS that particularly affect to specialized organs or systems including the nervous system, the cardiovascular system, the lung, the liver and the kidney.

    In recent decades, minimizing the frequency of nutrient deficiency and malnutrition in rural areas of developing
    countries becomes an alarming issue. Oyster mushrooms are rich source of both macro and micro nutrients. The
    objective of this paper was to evaluate the yield of newly introduced oyster mushroom strains viz. Pleurotus sajorcaju
    (PSC), Pleurotus flabellatus (FLB), Pleurotus florida (FLO), Pleurotus ostreatus (PO2
    and PO3
    ), Pleurotus ostreatus
    (HK-51) and Pleurotus geesteranus (PG1
    and PG3
    ) and to justify their nutritional values when grown in the climatic
    condition of Bangladesh. Strain HK-51 produced the highest amount of fresh sporophore (197.80 g). In contrast, the
    highest number of fruiting body was obtained from the strain FLO (82 g) followed by strain PSC (69 g). Strain PG1 has
    recorded the highest biological yield (278 g), productivity (55%) and biological efficiency (96%). Nutrient and mineral
    analysis of sporophore of strain PG1 showed protein (31.80%), lipid (3.6%), potassium (1.3 mg/100 g), phosphorus
    (0.8 mg/100 g), calcium (32 mg/100 g), iron (43 mg/100 g), magnesium (12 mg/100 g), copper (3.5 mcg/100 g), zinc
    (12.5 mcg/100 g) and manganese (2.3 mcg/100 g). This study showed that the strain PG1
    performed well with regard to
    quality and productivity as compared to other strains. Hence, oyster mushroom strain PG1
    is a potential cheap source
    of nutrients and minerals to combat socioeconomic problems including malnutrition, diseases linked to malnutrition,

    Malaysian economy relies on palm oil industries as a driver for rural development. However, palm oil mill effluent
    (POME) that is generated from palm oil processing stages causes major environmental challenges. Before being
    released to the environment, POME treatment is crucial to comply with standard discharge limit. Microalgae have
    demonstrated excellent potential for phycoremediating POME and capturing CO2
    . In this study, local microalgae isolate
    such as Chlamydomonas sp. UKM 6 and Chlorella spp. UKM 8 were used for POME treatment in 21 days with different
    inoculum sizes (5%, 10% and 15%). In addition, an integrated treatment process was performed by taking the treated
    POME supernatant for cultivation of Chorella spp. UKM 2, Chorella sorokiniana UKM 3 and Chlorella vulgaris for CO2
    sequestration study. Different CO2
    concentrations (5%, 10% and 15%) were used and the experiments were carried
    out in 10 days under continuous illumination. The results showed that among two species involves in POME treatment,
    Chlamydomonas sp. UKM 6 showed a great potential to remove pollutant such as COD (56%), nitrogen (65%) and
    phosphorus (34%). The biomass after POME treatment and CO2
    biofixation content high lipid (90 mg lipid/g biomass)
    which can be the potential source for biodiesel production. In CO2
    sequestration study, C. sorokininana UKM3 able
    to takes up to 15% CO2

    A strict and adherence treatment is required by the patient with diabetes mellitus and it demands a proper self-medication by the patient. Pharmacists are involved in providing self-management support to the patients. This review evaluates the interventions of pharmacist for patients to improve self-management with diabetes mellitus and also to improve the clinical outcomes of diabetes mellitus. A comprehensive literature search was performed by using different keywords "pharmacist-led intervention," "diabetes," "effect of pharmacist on outcome of diabetes," and "self-management of diabetes" with the help of various electronic databases such as PubMed, Science Direct, Embase, Web of Science, and the Cochrane Library from the beginning of the database through September 2018. The primary outcome was glycated hemoglobin (HbA1c), whereas the secondary outcomes were blood glucose level, blood pressure (BP) measure, body mass index, lipids, adherence to medication, and quality of life. Twenty-five studies comprising 2997 diabetic patients were included in the analysis. Pharmacist-led intervention was involved in all included studies in the form of education on diabetes and its complications, medication adherence, lifestyle, and education about self-management skills. Pharmacist-led interventions are able to reduce HbA1c levels with a mean of 0.75%. Most studies do not expose the material and methods used in pharmacist-led intervention. The variation in the reduction of HbA1c, fasting blood sugar, BP, and lipid profile was due to the lack of this standardization. The included studies indicated that pharmacist-led interventions in diabetes mellitus can significantly improve the outcomes of diabetes mellitus and its complication later on. Hence, these long-term improvements in outcomes added more value of pharmacists in health-care system of the world.

    A gold nanoparticle (AuNP) has a localized surface plasmon resonance peak depending on its size, which is often utilized for surface-enhanced Raman scattering (SERS). To obtain information on the cholesterol (Chol)-incorporated lipid membranes by SERS, AuNPs (5, 100 nm) were first functionalized by 1-octanethiol and then modified by lipids (AuNP@lipid). In membrane surface-enhanced Raman spectroscopy (MSERS), both signals from 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC) and Chol molecules were enhanced, depending on preparation conditions (size of AuNPs and lipid/AuNP ratio). The enhancement factors (EFs) were calculated to estimate the efficiency of AuNPs on Raman enhancement. The size of AuNP100nm@lipid was 152.0 ± 12.8 nm, which showed an surface enhancement Raman spectrum with an EF2850 value of 111 ± 9. The size of AuNP5nm@lipid prepared with a lipid/AuNP ratio of 1.38 × 104 (lipid molecule/particle) was 275.3 ± 20.2 nm, which showed the highest enhancement with an EF2850 value of 131 ± 21. On the basis of fluorescent probe analyses, the membrane fluidity and polarity of AuNP@lipid were almost similar to DOPC/Chol liposome, indicating an intact membrane of DOPC/Chol after modification with AuNPs. Finally, the membrane properties of AuNP@lipid systems were also discussed on the basis of the obtained MSERS signals.

    Nowadays, many of the tropical fruits have been commercialized worldwide due to increasing demand. In 2018, global tropical fruit has reached an unprecedented peak of 7.1 million tonnes. As such, a lot of large scale farming has been initiated to cultivate the fruit for commercialization. The nature of tropical fruit is perishable make the fruit easily undergo post-harvest losses especially when the fruit travels in a long distance for distribution. Losses of tropical fruit is estimated around 18-28% after harvesting. Then, the losses will continually develop during the trading process. Applying fruit coating on the fruit can minimize substantial privation. This article compendiously reviews the needs of coating and discuss different types of coating materials. The efficiency of different coating materials; polysaccharide, protein, lipid and composite based coating on tropical fruit is highlighted. There are various types of coating available for major fruit such as banana, mango, pineapple and avocado that can effectively extend the post-harvest life, minimize water loss, reduce chilling injuries and fight against post-harvest disease. Coating from minor fruit such as durian, rambutan, passion-fruit and mangosteen are still limited especially made from lipid and protein coating. In choosing the most appropriate coating for tropical, the nature of fruit needs to be understood. In addition, the chemistry of coating components and techniques of application is important in modulating the fruit quality.

    Background: Accumulative evidences on the beneficial effects of palm oil are progressively reported; however, there are still several controversies related to their effects on the risks of cardiovascular disease (CVD). This review explores the effects of palm oil and its liquid fraction namely palm olein, which is commonly used as cooking oil on four lipid parameters; total cholesterol (TC), triglyceride (TG), high-density lipoprotein-cholesterol (HDL-C) and low-density lipoprotein-cholesterol (LDL-C), which play an important role as CVD-related biomarkers. A systematic review of the literature was conducted to identify the relevant studies on palm oil and the lipid parameters specifically focusing on the in-vivo animal model. Methods: A comprehensive search was conducted in Medline via EBSCOhost, Medline via OVID and Scopus. Studies were limited to the English language published between the years of 2000 and 2019. The main inclusion criteria were as follows: (1) Study with in-vivo animal experiments [the animal should be limited to mammals] (2) Study should have evaluated the effects of palm oil or palm olein on plasma or serum lipid parameter (3) Study should have used palm oil or palm olein in the form of pure or refined oil (4) The treatment of palm oil or palm olein was assessed using the following outcomes: plasma or serum TC, TG, HDL-C, and LDL-C concentration (5) Study should have control group and (6) studies on specific fatty acid, fraction enriched tocotrienol and tocopherol, crude palm oil, kernel oil, red palm oil, thermally oxidized palm oil, hydrogenated palm oil, and palm oil or palm olein based products namely margarine, palm milk, butter and cream were excluded. The quality and the risk of bias on the selected studies were assessed using the ARRIVE Guideline and SYRCLE's Risk of Bias tools, respectively. Results: The literature search successfully identified 17 potentially relevant articles, whereby nine of them met the inclusion criteria. All research articles included in this review were in vivo studies comprising seven rats, one hamster and one mice model. Conclusion: Significant positive outcomes were observed in several lipid parameters such as TC and LDL-C. The evidence from this review supported that palm oil and palm olein possess high potential as lipid-lowering agents.

    Introduction:Acyclovir, a widely marketed antiviral drug is used for the treatment of Herpes Simplex infection. High doses of acyclovir are prescribed to patients to attain its maximum therapeutic effect due to its poor absorption and low oral bioavailability. The current therapeutics regiment of acyclovir are known to cause unwarranted adverse effects, thus prompted the need for a suitable drug carrier to improve the pharmacokinetic limitations. Develop-ment of solid lipid nanoparticles for oral delivery of acyclovir proposed in this study aimed to enhance acyclovir oral bioavailability. Methods: Comprehensive experiments and a series of optimization process were carried out to ensure reproducibility and assurance of product quality. The physicochemical characteristics of the solid lipid nanoparticles developed from plant-based solid lipid, Biogapress Vegetal 297 ATO with polysorbate 80 as an emul-sifying agent were also evaluated. Results: The spherical-shaped nanoparticles had an average size of 123 nm with good drug entrapment efficiency, up to 80%. The in vitro drug release study showed that solid lipid nanoparticles had prolonged acyclovir release in simulated intestinal fluid for 24 hours. The nanoparticles formulation was con-sidered stable during storage at refrigerated temperature for at least three months. In vivo oral bioavailability study showed that acyclovir-loaded solid lipid nanoparticles possessed superior oral bioavailability when compared with the commercial acyclovir suspension. Conclusion: In conclusion, this study exhibited the feasibility of solid lipid nanoparticles as an oral delivery vehicle for acyclovir and therefore represent a new promising therapeutic concept of nanoparticulate delivery system.

    Acyclovir is an antiviral drug used for the treatment of herpes simplex virus infection. Its oral bioavailability is low; therefore, frequent and high doses are prescribed for optimum therapeutic efficacy. Moreover, the current therapeutic regimen of acyclovir is associated with unwarranted adverse effects, hence prompting the need for a suitable drug carrier to overcome these limitations. This study aimed to develop solid lipid nanoparticles (SLNs) as acyclovir carriers and evaluate their in vivo pharmacokinetic parameters to prove the study hypothesis. During the SLN development process, response surface methodology was exploited to optimize the composition of solid lipid and surfactant. Optimum combination of Biogapress Vegetal 297 ATO and Tween 80 was found essential to produce SLNs of 134 nm. The oral bioavailability study showed that acyclovir-loaded SLNs possessed superior oral bioavailability when compared with the commercial acyclovir suspension. The plasma concentration of acyclovir-loaded SLNs was four-fold higher than the commercial suspension. Thus, this investigation presented promising results that the method developed for encapsulation of acyclovir offers potential as an alternative pathway to enhance the drug's bioavailability. In conclusion, this study exhibited the feasibility of SLNs as an oral delivery vehicle for acyclovir and therefore represents a new promising therapeutic concept of acyclovir treatment via a nanoparticulate drug delivery system.

    Classical homeopathy was shown to be beneficial in climacteric syndrome in many studies, but the clinical effect is unclear. To inspect if individualized classical homeopathy has a role in treating complaints after surgical menopause through real world case, we present a case of a 54-year-old Russian woman treated with individualized classical homeopathy for multimorbid conditions after surgical menopause examined for changes from homeopathic treatment. We assessed changes in climacteric symptoms, changes in comorbidities, and the general well-being of the patient. The woman had severe climacteric syndrome, pelvic inflammatory disease, dyslipidemia, obesity, hepatic steatosis, pancreatic lipomatosis, gall bladder disease, and mild subclinical hypothyroidism to begin with. She was treated with individualized classical homeopathy and followed up for 31 months. She was relieved of the vasomotor symptoms and psychological disturbances of climacteric syndrome, her weight reduced, the ultrasound scan showed absence of lipomatosis/gall bladder disease/hepatic steatosis. Blood tests showed reduction of thyroid stimulating hormone and a balance in the lipid status. Individualized classical homeopathy may have a role in the climacteric syndrome and comorbidities after surgical menopause. The efficacy of homeopathic therapy in climacteric problems must be scientifically investigated further.

    This study investigated combination nanocarrier and microwave system for α-tocopherol and γ-tocotrienol delivery against dermatitis, without skin thinning effect of steroids. The vitamin E was formulated into water-rich/water-poor nanoemulsions, and had their droplet size, zeta potential, morphology, therapeutic content, encapsulation efficiency and release, in vitro skin therapeutics/nanoemulsion penetration, retention and permeation profiles, and in vivo pharmacodynamics characteristics examined, with skin pre-treated by precision microwave when applicable. The nanoemulsions had droplet sizes <150 nm and negative zeta potential values. The skin pre-treatment by microwave (1 mW/3985 MHz) promoted therapeutics accumulation in epidermis through enhancing nanoemulsion penetration into skin. The combination nano- and microwave technologies fluidized skin lipid and protein domains with epidermal microstructures being fluidized to a greater extent than dermis, allowing a relatively high epidermal-to-dermal nanoemulsion distribution. Microwave of lower or higher than 3985 MHz brought about lower skin therapeutics/nanoemulsion accumulation due to insufficient lipid/protein domain fluidization or microwave-skin interaction limiting at skin surfaces only. Using water-rich nanoemulsion with higher therapeutic release and skin pre-treatment with 3985 MHz microwave, dermatitis was alleviated in vivo without skin thinning of standard steroid. The use of combination microwave and nanotechnology promotes vitamin delivery and translates to positive dermatitis treatment outcome that warrants future investigation.
