    The present study was aimed at evaluating antihyperglycemic and antihyperlipidemic activity of nuciferin and
    norcoclaurine constituents of N. nucifera seeds, a well-known medicinal plant. The alloxan (100 mg/kg b.w) induced
    diabetic rats (200-250 g) were divided into seven groups (n = 6). Group I; normal control, Group II; diabetic control,
    Group III; standard, Group lV-VII were fed with methanolic crude extracts (100, 200 mg/kg), nuciferin and norcoclaurine
    (10 mg/kg b.w.), received for 15 days in dose dependent manner. The study included different parameters; examination of
    oral glucose, fasting blood glucose, serum lipid profile and checking for body weight changes. In oral glucose examination,
    within 60 and 80 min of treatment, extracts, nuciferin and norcoclaurine significantly reduced blood glucose (p<0.05)
    and restored body weight in diabetic rats. Alloxan- induced diabetic rats showed 30-50% reduction of blood glucose
    level (p<0.05) and recovered 5-20% body weight at day 15 after ingestion of crude extracts (100-200 mg/kg b.w.); and
    nuciferin and norcoclaurine (each at 10 mg/kg b.w.). It also recovered significantly elevated biochemical parameters such
    as triglycerides (TG), low density lipoprotein (LDL), high density lipoprotein (HDL), total cholesterol (TC), serum urea and
    creatinine. Our findings indicated that N. nucifera seeds possess significant antihyperglycemic and antihyperlipidemic
    activity in diabetic rats.

    Medicine use review is a tool to improve medication adherence and safety. Current narrative review was planned to explore global policies and practices of medicine use review by community pharmacists in chronic diseases and its impact and way forward for low- and middle-income countries. Key words, such as ″medicine use review″, ″medication therapy management″ and ″community pharmacy″ were used for search on PubMed and CINAHL databases for articles published from 2004 to 2019. Medicine use review has opened an avenue of ongoing collaboration between community pharmacists and general practitioners. High-income countries have witnessed a gradual yet cautious adoption of these services through effective policy shift. In terms of practices and impact, the situation in high-income countries was promising where on an average ″type-II″ medicine use review was widely in practice and had improved clinical, humanistic and economic outcomes in chronic disease. However, in low- and middle-income countries, a paucity of effective policies was noted. Nevertheless, an emergent recognition of the potential of community pharmacists to contribute to the management of chronic diseases was evident.

    This study is a scholarly effort to broaden the existing literature on the impact of transportation services, urbanization, and financial development on ecological footprints in Pakistan. Data used in this study covers the period of 39 years from 1980 to 2018. This study adopted the QARDL model to tackle the non-linear association of variables and test their long-run stability across the different quantiles. The findings of this study indicated a significant negative association of transportation services and financial development with ecological footprints in Pakistan at almost all quantiles whereas, the urban population was found to be positively associated with the ecological footprint in Pakistan. Results also justify the existence of the EKC hypothesis in the scenario of Pakistan. Policymakers are advised to frame strategies for investors to invest more in eco-friendly projects to curtail the ecological footprints in Pakistan. Minimizing the dependency of the transportation sector on fossil fuel, and increased use of energy-efficient appliances in the urban population would be beneficial to control the negative influence on ecological footprints in Pakistan.

    Cephradine belongs to the first generation cephalosporin having a broad range of anti-bacterial activities. In the
    present work, Cephradine wasreacted with different metal salts. These metal salts were Iron, Copper, Cobalt and Nickel
    salts. All the complexes of Cephradine metals were synthesized at room temperature using a mechanical vibrator.
    The reactions yielded the coordinated complexes within 5-10 min with improved product yield. The synthesized
    complexes were analyzed for their antibacterial power using disc diffused assay. All the Cephradine complexes showed
    powerful antibacterial activity. The Co, Cu, Ni and Sn complexes showed good antibacterial activities 18.5 mm by Cu
    complexes against S. typhi, 17 mm against B. subtillus 16.5 mm against S. aureus, 16 mm against S. coccus. Similarly
    Sn complexes exhibited 17 mm zone of inhibition against S. coccus and 15.5 mm against B. subtillus. Cobalt and Ni
    complexes also shed significant inhibition activities against bacterial pathogenic bacterial strains. The study is of
    particular importance and new, using mechanical vibrator for the first time. The product yield is also comparatively
    good with short reaction time.

    Pathophysiological changes in diabetes like hyperglycemia, oxidative stress, insulin resistance and compensatory hyperinsulinemia predispose cells to malignant transformation and damage DNA repair mechanism. This study was designed to explore the potential synergistic toxic effects of anti-diabetic drug (Metformin), and an analgesic drug (Celecoxib) at cellular level. MTT assay run on Vero cell line revealed that the combinations of Metformin and Celecoxib augment the anti-proliferative effects, whereas Single cell gel electrophoresis spotlighted that Metformin produce non-significant DNA damage with the threshold concentration of 400μg/ml in peripheral blood mononuclear cells (lymphocytes and monocytes), while Celecoxib produced significant (P<0.05) DNA damage (class III comets) above the concentration of 75μg/ml, however the DNA damage or DNA tail protrusions by combinations of both drugs were less than what was observed with Celecoxib alone. Metformin or Celecoxib did not appear mutagenic against any mutant strains (TA 100 and TA 98) but their combination exhibited slight mutagenicity at much higher concentration. The results obtained at concentrations higher than the therapeutic level of drugs and reflect that Metformin in combination with Celecoxib synergistically inhibits the cell proliferation in a concentration dependent pattern. Since, this increase in cytotoxicity did not confer an increase in DNA damage; this combination could be adopted to inhibit the growth of malignant cell without producing any genotoxic or mutagenic effects at cellular level.

    OBJECTIVE: To investigate the effect on maternal and infant health of iron plus folate and multiple micronutrient supplements, along with deworming and health education session provided to pregnant women in rural, nonagrarian and food-insecure areas.

    METHODS: The quasi-experimental study was conducted in Tharparker and Umerkot districts, Sindh, Pakistan, in 2013-14, and comprised pregnant women in their earlier weeks of pregnancy. The enrolment and follow-up phase entailed 3 visits to each subject. Areas covered by lady health workers were designated as intervention areas, and those with non-LHW population were labelled as non-intervention areas.

    RESULTS: Of the 1204 subjects, 600(49.8%) were in the intervention group and 604(50.2%) were in the nonintervention group. By the end of the follow-up phase, significantly more women had increased number of meals in the intervention group compared to the non-intervention group (p<0.001). There was a significantly higher increase in mean haemoglobin levels and body mass index of women in the intervention arm after 3 and 6 months of interventions (p<0.05). Significantly higher mean birth weight was recorded in intervention areas compared to nonintervention areas (p<0.05).

    CONCLUSIONS: Community-based provision of multiple micronutrients to women along with deworming, health education and dietary counselling significantly reduced the prevalence of anaemia and reduced the incidence of low birth weight.

    Post-operative surgical site infections (SSI) present a serious threat and may lead to complications. Currently available dressings for SSI lack mucoadhesion, safety, efficacy and most importantly patient compliance. We aimed to address these concerns by developing a bioactive thiolated chitosan-alginate bandage embedded with zinc oxide nanoparticles (ZnO-NPs) for localized topical treatment of SSI. The FTIR, XRD, DSC and TGA of bandage confirmed the compatibility of ingredients and modifications made. The porosity, swelling index and lysozyme degradation showed good properties for wound healing and biodegradation. Moreover, in-vitro antibacterial activity showed higher bactericidal effect as compared to ZnO-NPs free bandage. In-vivo wound healing in murine model showed significant improved tissue generation and speedy wound healing as compared to positive and negative controls. Over all, thiolated bandage showed potential as an advanced therapeutic agent for treating surgical site infections, meeting the required features of an ideal surgical dressing.

    BACKGROUND: There is a growing global interest in formulating such policies and strategic plans that help devise collaborative working models for community pharmacists (CPs) and general practitioners (GPs) in primary care settings.

    OBJECTIVE: To conceptualize a stakeholder-driven framework to improve collaboration between CPs and GPs in Malaysian primary care to effectively manage medicines in chronic diseases.

    DESIGN AND SETTING: A qualitative study that involved individual semi-structured interviews of the leadership of various associations, guilds, and societies representing CPs, GPs, and Nurses in Malaysia.

    METHODS: This study collected and reported data in accordance with the guidelines of the Consolidated Criteria for Reporting of Qualitative Studies. Key informants were recruited based on purposive (expert) sampling. Interviews were transcribed verbatim and data were coded based on the principles of thematic analysis in NVivo.

    RESULTS: A total of 12 interviews (5 CPs, 5 GPs, and 2 nurses) were conducted. Five themes emerged: Theme 1 highlighted a comparison of community pharmacy practice in Malaysia and developed countries; Theme 2 involved current practices in Malaysian primary care; Theme 3 encompassed the advantages of CP-GP collaboration in chronic diseases; Theme 4 highlighted the barriers which impede collaboration in Malaysian primary care; and Theme 5 delineated the way forward for CP-GP collaboration in Malaysia.

    CONCLUSION: The actionable insights obtained from the Malaysian stakeholders offered an outline of a framework to enhance collaboration between CPs and GPs in primary care. Generally, stakeholders were interested in CP-GP collaboration in primary care and identified many positive roles performed by CPs, including prescription review, adherence support, and patient education. The framework of the way forward includes: separation of CP and GP roles through a holistic revision of relevant legislation to grant an active role to CPs in chronic care; definition of protocols for collaborative practices; incentivization of both stakeholders (CPs and GPs); and design and implementation of an effective regulatory mechanism whereby the Malaysian Ministry of Health may take a leading role.

    In recent years, antibiotic pollution has become a major environmental concern. The extensive production and widespread use of prescribed antibiotics have significantly impacted ecosystems. The main objective of the present study is to investigate the photocatalytic degradation of the antibiotic norfloxacin (NFX) under visible light. In this work photocatalysis of NFX was demonstrated under the source of visible radiation by using carbon dopped-titania (C-TiO 2 ) nanoparticles as catalyst prepared by a modified sol-gel method using n-hexane and benzene as carbon precursors. The synthesized samples were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), and energy dispersive X-ray (EDX) techniques. The effect of various parameters like initial concentration, catalyst dosage, irradiation time, pH, and inorganic ions were investigated on the photocatalysis of NFX. The XRD and SEM analysis exhibits that the synthesized C-TiO 2 nanoparticles were of anatase phase having spherical shape with a mean particle size of about 11-17 nm. The results shows that the best photocatalytic efficiency (74 % & 81 %) was achieved at pH = 8 in 150 min. The degradation of NFX follows pseudo-2nd -order kinetics, while favors Langmuir isotherm model. The inhibition effect of various inorganic ions on the photocatalysis of NFX was in the order of F⁻>SO4 2⁻>HCO3 ⁻>NO3 ⁻. The present study shows that C-TiO 2 is an optimistic and efficient catalyst for the photocatalysis of NFX antibiotics.

    Unwanted agricultural waste is largely comprised of lignocellulosic substrate which could be transformed into sugars. The production of bioethanol from garbage manifested an agreeable proposal towards waste management as well as energy causation. The goal of this work is to optimize parameters for generation of bioethanol through fermentation by different yeast strains while Saccharomyces cerevisiae used as standard strain. The low cost fermentable sugars from pomegranate peels waste (PPW) were obtained by hydrolysis with HNO3 (1 to 5%). The optimum levels of hydrolysis time and temperature were elucidated via RSM (CCD) ranging from 30 to 60 min and 50 to 100 °C respectively. The result shows that optimum values (g/L) for reducing sugars was 61.45 ± 0.01 while for total carbohydrates was 236 ± 0.01. These values were found when PPW was hydrolyzed with 3% HNO3, at 75 °C for one hour. The hydrolyzates obtained from the dilute HNO3 pretreated PPW yielded a maximum of 0.43 ± 0.04, 0.41 ± 0.03 g ethanol per g of reducing sugars by both Metchnikowia sp. Y31 and M. cibodasensis Y34 at day 7 of ethanologenic experiment. The current study exhibited that by fermentation of dilute HNO3 hydrolyzates of PPW could develop copious amount of ethanol by optimized conditions.
