    Aqueous extracts of Zingiber officinale rhizomes were studied to evaluate their antidiabetic effects on protein glycation and on the diffusion of glucose in vitro in the present study. Zingiber officinale rhizome aqueous extract were examined at concentrations of 5, 10, 20 and 40 g/L. The antidiabetic effects were found to be dose-dependent. Antidiabetic potential of Zingiber officinale was mainly through inhibition of the glucose diffusion and to a limited extent by reducing the glycation. However, further studies are needed to determine in vitro effects of therapeutic potential by restraining postprandial glucose absorptions and plasma protein glycations in diabetic subjects.Extratos aquosos de rizomas Zingiber officinale foram estudados para avaliar os seus efeitos antidiabĂ©ticos em glicação de proteĂ­nas e sobre a difusĂŁo de glicose in vitro, no presente estudo. Extratos aquosos de Zingiber officinale foram examinados nas concentraçÔes de 5, 10, 20 e 40 g extrato de planta/L. Os efeitos antidiabĂ©ticos observados eram dependentes da dose. O potencial antidiabĂ©tico de Zingiber officinale se verificou, principalmente, atravĂ©s da inibição da difusĂŁo de glicose e, em menor extensĂŁo, atravĂ©s da redução da glicação.

    Objective: To compare motivation to become a doctor in both genders Study Design: Observational cross-sectional study Place and Duration of Study:  Rawalpindi Medical University in March 2019. Materials and Methods: First and second-year M.B.B.S students were included in the study. Age, year of study, and gender were recorded.  The questionnaire included 18 questions assessing six motivational dimensions: status and security; nature of the occupation; career opportunities; patient care and working with people; use of personal skills; and interest in science. Responses were recorded as ‘agree’ or ‘disagree’ for each question and results were analyzed using SPSS v19. Results: Out of 350 medical students, 247 (70.6%) were female and 103 (29.4%) were male. Most frequent motivational factors for females were “Opportunity to care for/ help people” (n=240; 97.1%) followed by “responsible job” (n=220; 89%) and “use of mental skills” (n=217; 87.8%). Male students were motivated mostly by “use of mental skills” (n=90; 87.3%) followed by “provides secure career” (n=87; 84.4%) and “challenging field” (n=83; 80.5%). In our study, (n=61; 25%) of females responded in agreement that boosts in marriage perspective was an underlying motivational factor for their choice of studying medicine while (n=41; 40%) males agreed to it. There was a significant difference between both genders with a p-value of 0.005.  Conclusions: We infer that female medical students have more humanitarian grounds for choosing the medical profession and are more motivated than their male counterparts

    Potential of Functionalized Magnetite (Fe3O4) in Decontamination of Pathogenic Bacteria from Milk

    Get PDF
    Magnetite (Fe3O4) is getting popular due to its super-paramagnetic properties, high biocompatibility and lack of toxicity to humans. Magnetite (Fe3O4) nanoparticles have high surface energy thus these nanoparticles aggregate quickly. This aggregation strongly affects the efficiency of these nanoparticles. So these magnetite nanoparticles are coated with organic or inorganic substance to prevent aggregation. These coatings not only stabilize magnetic nanoparticles but can also be used for further functionalization. The aim of this study was to evaluate the efficiency of functionalized magnetite to remove pathogenic bacteria (E.coli and B.cereus) from milk considering binding capability of magnetite with bacterial cell wall. Magnetite (Fe3O4) was prepared by co-precipitation method and subsequently functionalized with oleic acid (OA) and ethylene diamine (EDA). In present study role of magnetite (Fe3O4) and functionalized magnetite (EDA-Fe3O4, OA-Fe3O4) in removal of pathogenic bacteria (E.coli and B.cereus) from milk was investigated. The morphology of functionalized magnetite was determined by Scanning Electron microscopy (SEM). Their removal efficiency was studied based on time (10, 20 and 30 minutes). Concentration of uncoated magnetite (Fe3O4) and coated magnetite (EDA-Fe3O4, OA-Fe3O4) was fixed at 4mg/50mL. Magnetite was successfully synthesized in range of +/- 3nm. Highest capturing efficiency (74.45%) of oleic acid magnetite (OA-Fe3O4) was observed for Bacillus cereus at 30 minutes. However for Escherichia coli, both ethylene-diamine magnetite (EDA-Fe3O4) and oleic acid magnetite (OA-Fe3O4) showed maximum capturing efficiency (61.65% and 63.91% respectively). It was concluded from the study that magnetite coated with oleic acid and ethylenediamine removed pathogenic bacteria from milk efficiently. However, more research is required to study the effect of these magnetic nanoparticles on nutritional composition of milk.Peer reviewe

    Multisystem inflammatory syndrome (MIS-C) in Pakistani children: A description of the phenotypes and comparison with historical cohorts of children with Kawasaki disease and myocarditis

    Objectives: To determine clinical, laboratory features and outcomes of Multisystem Inflammatory Syndrome in children (MIS-C) and its comparison with historic Kawasaki Disease (KD) and Viral Myocarditis (VM) cohorts.Methods: All children (1 month- 18 years) who fulfilled the World Health Organization criteria of MIS-C presenting to two tertiary care centers in Karachi from May 2020 till August 31st were included. KD and VM admitted to one of the study centers in the last five years prior to this pandemic, was compared to MIS-C.Results: Thirty children with median age of 24 (interquartile range (IQR)1-192) months met the criteria for MIS-C. Three phenotypes were identified, 12 patients (40%) with KD, ten (33%) VM and eight (26%) had features of TSS. Echocardiography showed coronary involvement in 10 (33%), and moderate to severe Left Ventricular dysfunction in 10 (33%) patients. Steroids and intravenous immunoglobulins (IVIG) were administered to 24 (80%) and 12 (41%) patients respectively while 7 (23%) received both. Overall, 20% children expired. During the last five years, 30 and 47 children were diagnosed with KD and VM, respectively. Their comparison with MIS-C group showed lymphopenia, thrombocytosis, and higher CRP as well as more frequent atypical presentation in MIS-C KD group with less coronary involvement. The MIS-C VM was more likely to present with fulminant myocarditis.Conclusions: Our MIS-C cohort is younger with higher mortality compared to previous reports. MIS-C is distinct from historic cohorts of KD and VM in both in clinical features and outcomes

    Goats play a vital role in the economy of common man. It acts as pivotal point in the uplift of socio-economic status of females. The goats are such delicate and fragile animals that encounter a lot of infectious and non-infectious diseases including viruses, bacteria and gastrointestinal parasites (GIP). The goat being a range animal is selective feeder. It needs a lot of managemental practices which safeguards its health. This chapter focuses on management, impact of gastrointestinal parasites, role of intestinal immunity, various breeds reared in Pakistan, role of plant based phytochemicals to treat against GIT parasites and various models to predict the status of health in animals

    Criss cross heart; a challenging diagnosis, case series

    No full text
    Crisscross heart (CCH) is a rare anomaly characterized by twisting of the inflow streams of right and left ventricles. The etiology of CCH is not known. Its frequency is less than 8/10, 00,000 live births. Cyanosis is common in neonatal age, while shortness of breath is the main presenting complaint in older children. We present a case series of CCH with array of associations, diagnosed by echocardiography. CCH is a rare heart defect that can be diagnosed by echocardiography by a vigilant operator. Early diagnosis is the key to successful management resulting in increased survival rate, better outcomes and improved quality of life. Keywords: Criss-Cross heart, mitral valve lesions, coarctation of aorta, Echocardiography, case series

    No full text
    Pulsus alternans is a well-recognized clinical entity in which alternating strong and weak pulses are detected. It usually is secondary to underlying myocardial failure. Murmur alternans (alternation in murmur intensity) has been described in aortic stenosis and a few right-sided lesions such as pulmonary hypertension and embolism. This report describes a case of murmur alternans in critical pulmonary stenosis that also showed Doppler alternans on echocardiography. The underlying cause was right ventricular systolic dysfunction
