    277-287The present study was conducted to record the ethnomedicinal plants and their uses by the Karbi tribe in Bichikri and Harlong sacred groves of West Karbi Anglong district of Assam. A prestructured questionnaire survey and quantitative analysis was carried out to record the medicinal plants and to determine the ailments categories. A total of 38 ethnomedicinal plants (36 genera and 27 families) were recorded from the study sites. Leaves were found as the dominant plant parts used for the treatment of various health ailments. The highest Fic value was recorded for cold, dermatological, skeletal muscle pain and inflammation, general health, and infectious disease and genital-urinary disorder categories. The informant agreement ratio (IAR) was found higher for 18 species. The fidelity level (FL) of 11 species secured the highest FL value (100%) and the used value (UV) was in the range of 0.05 to 0.93. The present study has revealed that the Karbi tribe living around the sacred groves depends on the plant species for their health care. However, proper management is required for the conservation of sacred groves through sustainable utilization of medicinal plants occurred in the groves

    Background: The bone marrow examination is a useful and cost-effective diagnostic procedure in haematological practice for the diagnosis of haematological disorders. It may either confirm the clinically suspected disease or may provide the previously unsuspected diagnosis. The bone marrow examination can be done by bone marrow aspiration as well as by performing bone marrow biopsy. The aim of the study is to compare the diagnostic accuracy and rate of concordance between two modalities of bone marrow examination in diagnosis of haematological malignancies. Methods: The study was conducted at haematology section of the Department of Pathology, Government Medical College, Jammu spanned over a period of 2.5 years from June 2020 to December 2022. The clinical data along with physical examination, relevant haematological, biochemical and radiological investigations were also reviewed. After taking the informed consent bone marrow aspiration and bone marrow biopsy were done under aseptic precautions. Results: A total of 250 cases of haematological malignancies were studied over a 2.5 year period. The most common haematological malignancy was found to be leukemia 194 (77.6%) cases, followed by plasma cell dyscrasia with 30 (12%) cases, lymphomas and myeloproliferative disorders each with 11 (4.4%) cases and metastatic deposits 4 (1.6%) cases. In the present study, 64/250 (25.6%) patients underwent BMA and trephine biopsy simultaneously. A positive concordance was seen in 46 (71.8%) of the cases between the two methods and diagnostic discordance was observed in 10 (16.3%) of the cases. Conclusions: Bone marrow aspiration and biopsy both complement each other and should be evaluated simultaneously. This study emphasizes the need for greater vigilance in the early diagnosis and an interdisciplinary approach for the effective management of patients as well as inclusion of trephine biopsy as regular procedure for complete evaluation of patients with haematological malignancies

    Background: Preeclampsia is idiopathic multisystem disorder specific to human pregnancy. Its incidence is 8-10% of total pregnancies in India. It is one of the leading causes of maternal and fetal morbidity and mortality worldwide. Alterations in serum calcium and magnesium levels have been suggested as effective factors in causing preeclampsia. The aim of this study was to compare serum calcium and magnesium levels in preeclamptic and normal pregnant women in third trimester of pregnancy.Methods: The study was conducted in the department of biochemistry in collaboration with department of obstetrics and gynaecology, Sri Aurobindo medical college & P. G. institute, Indore during the period January 2012 to January 2013. Subjects were divided into two groups: group-I included 100 preeclamptic women group-II included 100 age matched, healthy pregnant women. Serum calcium and magnesium was estimated by Arsenazo III method and by Calmagite method in ERBA CHEM-5 respectively (Enzymatic kit method).Results: Serum levels of calcium (8.27 ± 0.37 mg/dL vs. 9.06 ± 0.27 mg/dL) and magnesium (1.99 ± 0.13 mEq/L vs. 2.03 ± 0.13 mEq/L) were significantly lower in preeclamptic women than the control group (i.e. healthy pregnant women).Conclusions: Hypocalcaemia and hypomagnesaemia are seen in the preeclamptic women may be responsible for the vascular pathology associated with onset of preeclampsia. Hence it can be concluded that adjuvant supplementation of calcium and magnesium may prevent further progression of preeclampsia.

    Doping Independent Work Function and Stable Band Gap of Spinel Ferrites with Tunable Plasmonic and Magnetic Properties

    Tuning optical or magnetic properties of nanoparticles, by addition of impurities, for specific applications is usually achieved at the cost of band gap and work function reduction. Additionally, conventional strategies to develop nanoparticles with a large band gap also encounter problems of phase separation and poor crystallinity at high alloying degree. Addressing the aforementioned trade-offs, here we report Ni–Zn nanoferrites with energy band gap (Eg) of ≈3.20 eV and a work function of ≈5.88 eV. While changes in the magnetoplasmonic properties of the Ni–Zn ferrite were successfully achieved with the incorporation of bismuth ions at different concentrations, there was no alteration of the band gap and work function in the developed Ni–Zn ferrite. This suggests that with the addition of minute impurities to ferrites, independent of their changes in the band gap and work function, one can tune their magnetic and optical properties, which is desired in a wide range of applications such as nanobiosensing, nanoparticle based catalysis, and renewable energy generation using nanotechnology

    Photocatalytic inactivation of viruses using graphitic carbon nitride-based photocatalysts:Virucidal performance and mechanism

    Get PDF
    The prevalence of lethal viral infections necessitates the innovation of novel disinfection techniques for contaminated surfaces, air, and wastewater as significant transmission media of disease. The instigated research has led to the development of photocatalysis as an effective renewable solar-driven technology relying on the reactive oxidative species, mainly hydroxyl (OH●) and superoxide (O2●−) radicals, for rupturing the capsid shell of the virus and loss of pathogenicity. Metal-free graphitic carbon nitride (g-C3N4), which possesses a visible light active bandgap structure, low toxicity, and high thermal stability, has recently attracted attention for viral inactivation. In addition, g-C3N4-based photocatalysts have also experienced a renaissance in many domains, including environment, energy conversion, and biomedical applications. Herein, we discuss the three aspects of the antiviral mechanism, intending to highlight the advantages of photocatalysis over traditional viral disinfection techniques. The sole agenda of the review is to summarize the significant research on g-C3N4-based photocatalysts for viral inactivation by reactive oxidative species generation. An evaluation of the photocatalysis operational parameters affecting viral inactivation kinetics is presented. An overview of the prevailing challenges and sustainable solutions is presented to fill in the existing knowledge gaps. Given the merits of graphitic carbon nitride and the heterogeneous photocatalytic viral inactivation mechanism, we hope that further research will contribute to preventing the ongoing Coronavirus pandemic and future calamities

    Utilising copper screen-printed electrodes (CuSPE) for the electroanalytical sensing of sulfide

    Get PDF
    © The Royal Society of Chemistry 2016.A mediatorless sulfide electrochemical sensing platform utilising a novel nanocopper-oxide screen-printed electrodes (CuSPE) is reported for the first time. The state-of-the-art screen-printed electrochemical sensors demonstrate their capability to quantify sulfide within both the presence and absence of an array of interferents with good levels of sensitivity and repeatability. The direct sensing (using linear sweep voltammetry) of sulfide utilising the CuSPEs provides a mediatorless approach for the detection of sulfide, yielding useful analytical signatures that can be successfully quantified. The proposed novel protocol using the CuSPEs is successfully applied to the sensing of sulfide within drinking water exhibiting a high level of recovery

    Measuring routine childhood vaccination coverage in 204 countries and territories, 1980-2019 : a systematic analysis for the Global Burden of Disease Study 2020, Release 1

    Background Measuring routine childhood vaccination is crucial to inform global vaccine policies and programme implementation, and to track progress towards targets set by the Global Vaccine Action Plan (GVAP) and Immunization Agenda 2030. Robust estimates of routine vaccine coverage are needed to identify past successes and persistent vulnerabilities. Drawing from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2020, Release 1, we did a systematic analysis of global, regional, and national vaccine coverage trends using a statistical framework, by vaccine and over time. Methods For this analysis we collated 55 326 country-specific, cohort-specific, year-specific, vaccine-specific, and dosespecific observations of routine childhood vaccination coverage between 1980 and 2019. Using spatiotemporal Gaussian process regression, we produced location-specific and year-specific estimates of 11 routine childhood vaccine coverage indicators for 204 countries and territories from 1980 to 2019, adjusting for biases in countryreported data and reflecting reported stockouts and supply disruptions. We analysed global and regional trends in coverage and numbers of zero-dose children (defined as those who never received a diphtheria-tetanus-pertussis [DTP] vaccine dose), progress towards GVAP targets, and the relationship between vaccine coverage and sociodemographic development. Findings By 2019, global coverage of third-dose DTP (DTP3; 81.6% [95% uncertainty interval 80.4-82 .7]) more than doubled from levels estimated in 1980 (39.9% [37.5-42.1]), as did global coverage of the first-dose measles-containing vaccine (MCV1; from 38.5% [35.4-41.3] in 1980 to 83.6% [82.3-84.8] in 2019). Third- dose polio vaccine (Pol3) coverage also increased, from 42.6% (41.4-44.1) in 1980 to 79.8% (78.4-81.1) in 2019, and global coverage of newer vaccines increased rapidly between 2000 and 2019. The global number of zero-dose children fell by nearly 75% between 1980 and 2019, from 56.8 million (52.6-60. 9) to 14.5 million (13.4-15.9). However, over the past decade, global vaccine coverage broadly plateaued; 94 countries and territories recorded decreasing DTP3 coverage since 2010. Only 11 countries and territories were estimated to have reached the national GVAP target of at least 90% coverage for all assessed vaccines in 2019. Interpretation After achieving large gains in childhood vaccine coverage worldwide, in much of the world this progress was stalled or reversed from 2010 to 2019. These findings underscore the importance of revisiting routine immunisation strategies and programmatic approaches, recentring service delivery around equity and underserved populations. Strengthening vaccine data and monitoring systems is crucial to these pursuits, now and through to 2030, to ensure that all children have access to, and can benefit from, lifesaving vaccines.
