ABSTRACT
Abstract Diabetes mellitus (DM), an endocrine syndrome characterized by high blood glucose levels due to abrogated insulin activity. The existing treatments for DM have side effects and varying degrees of efficacy. Therefore, it is paramount that novel approaches be developed to enhance the management of DM. Therapeutic plants have been accredited as having comparatively high efficacy with fewer adverse effects. The current study aims to elucidate the phytochemical profile, anti-hyperlipidemic, and anti-diabetic effects of methanolic extract D. salicifolia (leaves) in Alloxan-induced diabetic mice. Alloxan was injected intraperitoneally (150 mg kg-1, b.w), to induced diabetes in mice. The mice were divided into three groups (n=10). Group 1 (normal control) received normal food and purified water, Group II (diabetic control) received regular feed and clean water and group III (diabetic treated) received a methanolic extract of the plant (300 mg kg-1) for 28 days with a typical diet and clean water throughout the experiment. Blood samples were collected to checked serum glucose and concentration of LDL, TC, TG. The extract demonstrated significant antihyperglycemic activity (P 0.05), whereas improvements in mice's body weight and lipid profiles were observed after treatment with the extract. This study establishes that the extract has high efficacy with comparatively less toxicity that can be used for DM management.
Resumo Diabetes mellitus (DM) é uma síndrome endócrina caracterizada por níveis elevados de glicose no sangue devido à atividade anulada da insulina. Os tratamentos existentes para o DM têm efeitos colaterais e vários graus de eficácia. Portanto, é fundamental que novas abordagens sejam desenvolvidas para aprimorar o manejo do DM. As plantas terapêuticas foram acreditadas como tendo eficácia comparativamente alta com menos efeitos adversos. O presente estudo visa elucidar o perfil fitoquímico, efeitos anti-hiperlipidêmicos e antidiabéticos do extrato metanólico de D. salicifolia (folhas) em camundongos diabéticos induzidos por aloxana. Alloxan foi injetado por via intraperitoneal (150 mg kg-1, b.w), para induzir diabetes em camundongos. Os camundongos foram divididos em três grupos (n = 10). Grupo 1 (controle normal) recebeu ração normal e água purificada, Grupo II (controle diabético) recebeu ração regular e água limpa, e o grupo III (tratamento diabético) recebeu extrato metanólico da planta (300 mg kg-1) por 28 dias com uma dieta típica e água limpa durante todo o experimento. Amostras de sangue foram coletadas para verificar a glicose sérica e a concentração de LDL, TC, TG. O extrato demonstrou atividade anti-hiperglicêmica significativa (P 0,05), enquanto melhorias no peso corporal e no perfil lipídico dos camundongos foram observadas após o tratamento com o extrato. Este estudo estabelece que o extrato tem alta eficácia com comparativamente menos toxicidade e pode ser usado para o controle do DM.
ABSTRACT
Abstract The present investigation was aimed to examine the concentrations of trace metals including e.g copper (Cu), manganese (Mn), nickel (Ni), and zinc (Zn) in water samples collected from nursery pond of grass carp (Ctenopharyngodon idella) in Bannu Hatchery of Khyber Pakhtunkhwa during the period from April 2018 to January 2019. The temperature and pH of each water sample were measured for the whole study duration. The concentration of Copper (Cu), Manganese (Mn), Nickel (Ni), and Zinc (Zn) in collected water samples were measured in mg/liter by using Atomic Absorption Spectrophotometer. The blank and standard solutions for device calibration Standard solutions i.e., 2.0 mg, 4.0 mg, and 6.0 were used to measure the concentration of these metals in water samples to verify the measurements. The data was statistically analyzed on descriptive statistics (estimation of proportions and standard deviation) used to summarize mean concentration. The results obtained of both temperature and pH of water samples were found in ranged 10 to 36 0C and 7.0 to 8.44; whereas the size of fry stages was ranged from 4.0 to 56.0 mm in total length. The results of investigated metals found in pond water samples are in order of Zn>Mn>Ni>Cu, respectively. As optimum temperature and pH for grass carp were mostly between 15 0C and 30 0C and pH 6.5 to 8.0. It was concluded from obtained results that temperature, pH, and trace metals were found appropriate for the growth of Ctenopharyngodon idella from fry to fingerling stages, but the highest amount of zinc can cause its mortality. It is a preliminary study on grass carp culturing in Bannu fish hatchery so, it would provide useful information for model fish seed production unit in a hatchery.
Resumo A presente investigação teve como objetivo examinar as concentrações de metais traço, incluindo cobre (Cu), manganês (Mn), níquel (Ni) e zinco (Zn) em amostras de água coletadas de viveiro de carpa-capim (Ctenopharyngodon idella) em Incubatório de Bannu de Khyber Pakhtunkhwa durante o período de abril de 2018 a janeiro de 2019. A temperatura e o pH de cada amostra de água foram medidos durante todo o período do estudo. A concentração de cobre (Cu), manganês (Mn), níquel (Ni) e zinco (Zn) nas amostras de água coletadas foi medida em mg / litro usando espectrofotômetro de absorção atômica. As soluções em branco e padrão para as soluções padrão de calibração do dispositivo, ou seja, 2,0 mg, 4,0 mg e 6,0, foram usadas para medir a concentração desses metais em amostras de água para verificar as medições. Os dados foram analisados estatisticamente em estatística descritiva (estimativa de proporções e desvio padrão) usada para resumir a concentração média. Os resultados obtidos tanto de temperatura quanto de pH das amostras de água variaram de 10 a 36 0C e 7,0 a 8,44, enquanto o tamanho dos estágios de alevinos variou de 4,0 a 56,0 mm no comprimento total. Os resultados dos metais investigados encontrados em amostras de água de lagoas são da ordem de Zn > Mn > Ni > Cu, respectivamente. A temperatura e o pH ótimos para a carpa-capim foram principalmente entre 15 0C e 30 0C e pH 6,5 a 8,0. Concluiu-se, a partir dos resultados obtidos, que temperatura, pH e traços de metais foram considerados adequados para o crescimento de Ctenopharyngodon idella desde os estágios de alevinos até alevinos, mas a maior quantidade de zinco pode causar sua mortalidade. É um estudo preliminar sobre a cultura da carpa-capim em incubatório de peixes Bannu, portanto forneceria informações úteis para modelo de unidade de produção de sementes de peixes em um incubatório.
ABSTRACT
Leech invasion into a bodily cavity or orifice is known as hirudiniasis. This article’s objective is to explain an uncommon cause of epistaxis brought on by a leech infestation in the nasal cavity, nasopharynx, or oropharynx in the hilly Rajouri district of Jammu and Kashmir, as well as how to manage it. This retrospective case series consisted of seven cases. All the cases present with unilateral epistaxis. Anterior rhinoscopy with or without endoscope reveal smooth, grayish-black mobile leech inside nasal cavity, nasopharynx, or oropharynx which was removed by suction or forcep.
ABSTRACT
Introduction: Parkinson’s disease (PD) is a neurological condition that impacts the physical and psychological functioning of the patients. The physical and cognitive changes come with social stigma and threats to roles previously associated with their identities. Objectives: The current paper attempts to study the influence of the disease on the personal identity of the patients. Methods: A systematic review was done on PD and personal identity following the Preferred Reporting Items for Systematic Reviews and Meta‑Analyses 2020 guidelines. The Consolidated Criteria for Reporting Qualitative Research checklist was used to assess the quality of the papers. The selected papers were synthesized to understand the relationship between PD and personal identity. Results: The emerging themes were: (1) dissociation of old personal identity: (1.1) Influence of physical symptoms, (1.2) influence of society and stigma, and (1.3) threats to roles associated with identity and (2) changing family dynamics. AModel of Personal, Family, and Disease Dynamics was also developed based on clinical first‑hand experience with the patients and the review. Conclusion: The personal identity of the PD patients shifts drastically as a result of their physical and psychosocial experiences. This also results in changed family dynamics, with the patient feeling sidelined due to loss of control and responsibilities in the family.
ABSTRACT
Aim: The aim of the present study was to identify biosurfactant produced by Pseudomonas aeruginosa and to determine the effectiveness of biosurfactants (rhamnolipid) against P. infestans causing late blight of potato. Methodology: Pseudomonas aeruginosa strains were isolated from soil samples and the potential strain PA 1, selected because of its antagonistic ability, was used to optimize anti-metabolite production and its characterization using HPLC-Mass spectrometry. Rhamnolipid based formulation was developed and its efficacy was tested against late blight disease. Results: The results revealed that four rhamnolipids congeners were identified, among them three were mono-rhamno-di-lipidic congeners and one was di-rhamno-di-lipdic congeners, abundantly present in the crude biosurfactant obtained from P. aeruginosa PA1. The mass spectra of mono-rhamno-di-lipidic Rha-C12-C14 peak value (m/z 584), Rha-C12.1-C10.CH3 peak value (m/z 545), Rha-C12-C-12-CH3 peak value (m/z 575) and di-rhamno-di-lipidic. Rha-Rha-C10-C10 peak value (m/z 651) were also detected. Rhamnolipid-based formulation was developed and evaluated at different concentration ranging from 0.012 and 0.3% in detached leaf test. Significant reduction in lesion area was recorded at 0.2% concentration (lesion area 0.06 cm2 as against 9.8 cm2 on 5th day of inoculation). Interpretation: Microbial produced rhamnolipid based formulation at 0.2% concentration was found effective against late blight of potato in detached leaf test. Further, it could be used in field study as green chemical which would help in replacing application of chemicals in agriculture.
ABSTRACT
Background: In elderly mental disorders are overlooked or underdiagnosed. Almost 20% of elderly above 60 years of age suffer from a mental or neurological disorder, and the most common ones are dementia and depression. Studies have pointed out the increased prevalence of depression in old‑age homes. Objectives: The objectives are as follows: (1) To estimate and compare the prevalence of geriatric depression among people living in public and private old‑age homes and (2) to study the factors associated with depression and compare the facilities in public and private old‑age homes. Materials and Methods: A cross‑sectional questionnaire‑based study was conducted among geriatric population in old‑age homes of Mysore. Depression was assessed using the short form of geriatric depression scale‑15, cognitive impairment using Mini‑Mental State Examination‑30. Data relating to sociodemographic variables and facility assessment were collected separately. Results: The overall prevalence of depression in old‑age homes of Mysore was 33.3% (46.3% in public and 21.6% in private old‑age homes with P = 0.002). The facilities offered and reason for stay also varied significantly across both homes. Marital status, education, economical dependency, and uncorrected impairment were the factors associated with depression. Among the psychosocial factors, feeling of loneliness, and neglect were significant predictors in both settings. Other psychosocial factors such as feeling satisfied by the status of their children’s life, advice taken by their children, financial and personal losses in the past 1 year, and presence in social events were significant predictors only in private old‑age home. Conclusion: Prevalence of depression in the old‑age homes differs significantly with the type of home, the facilities offered, and the reason cited by the inmates for admission probably is the contributing factor for the variation in depression.
ABSTRACT
Background: Helicobacter pylori infection is recognised as type 1 carcinogen by the International Agency of Research on Cancer. Previous studies in our hospital have revealed high prevalence of H. pylori in our population with a high recurrence rate after completion of treatment. This prompted us to undertake this study. Aim: This study aimed to determine common gene mutations leading to resistance to clarithromycin, metronidazole, tetracycline and quinolones in H. pylori in patients attending our hospital. Settings and Design: This is a cross-sectional hospital-based study. The study was approved by the Institutional Ethics Committee. Materials and Methods: This study was conducted on 196 adult dyspeptic patients with an indication for upper gastrointestinal endoscopy. Gastric biopsies collected from them were subjected to histopathological examination, rapid urease test (RUT) and culture. Of the 196 patients, 95 met the inclusion criteria. Drug susceptibility testing (DST) by various polymerase chain reaction-based methods was done for 47 RUT-positive biopsies and 13 H. pylori isolates. Results: Maximum resistance was seen to metronidazole (81.66%) followed by clarithromycin (45%) and quinolones (3.33%). No high-level resistance was seen to tetracycline. In clarithromycin-resistant cases, A2142G mutation was more prevalent than A2143G mutation. Multidrug resistance (resistance to metronidazole and clarithromycin) was seen in 41.66% of patients. Conclusions: Tetracycline and quinolones could be the antibiotics of choice in the eradication of H. pylori in this region, while recurrence of the infection with H. pylori could be expected among patients receiving either metronidazole or clarithromycin, for eradication therapy. DST should be done on a routine basis utilising both phenotypic and genotypic methods to prevent further emergence of resistance in this region.
ABSTRACT
Biofilms are adherent, multi-layered colonies of bacteria that are typically more resistant to the host immune response and routine antibiotic therapy. HA biomaterial comprises of a single-phased hydroxyapatite scaffold with interconnected pore structure. The device is designed as osteoconductive space filler to be gently packed into bony voids or gaps following tooth extraction or any surgical procedure. Gentamycin-coated biomaterial (locally made hydroxyapatite) was evaluated to reduce or eradicate the biofilm on the implant materials. The results indicated that the HA coated with gentamycin was biocompatible to human osteoblast cell line and the biofilm has been reduced after being treated with different concentrations of gentamycin-coated hydroxyapatite (HA).
