Infection status of Clinostomum complanatum (Rudolphi, 1819) metacercaria from Channa punctatus of Meerut District

Metacercaria Clinostomum complanatum is a digenetic trematode, which is mainly found in fresh water fishes. Present communication deals with the infection status of C. complanatum in C. punctatus of Meerut district, which is supported by the data spreading over one year. About 250 specimens of C. punctatus from different ponds of Meerut were studied through regular periodical collection in the year Jan 2010 to Dec 2010. Overall prevalence 35.6%, mean intensity 3.06 and abundance 1.09 were reported. The infection was maximum in winter and minimum in rainy season. Prevalence, intensity and abundance of the infestation were also found to be related to different length group and sex of the hosts, the medium sized fishes were more infected and the larger size fishes were less infected while the smaller size fishes showed moderate infection. Susceptibility of infection was not significantly different between male and female fish

DESIGN AND ANALYSIS OF THREE-PHASE SPLIT SOURCE INVERTER

In many DC-AC power conversions a voltage source inverter (VSI) along with an additional DC-DC boosting stage is required. To overcome this problem in VSI, a split source inverter is preferred. This paper presents a combination of boost stage and VSI stage as a single unit DC-AC power conversion named as split source inverter (SSI). The proposed topology require three additional diodes with same number of active switches of VSI and eight same states of conventional pulse width modulation. This work present the analysis of SSI with sinusoidal pulse width modulation technique. The developed SSI model is simulated on MATLAB/SIMULINK environment. Simulation results have been obtained for inverter voltage, inductor current, output line current and total harmonic distortion of output line current

Constructing Inverse Scattering Potentials for {\alpha}-{\alpha} System using Reference Potential Approach

Background: An accurate way to incorporate long range Coulomb interaction alongside short-range nuclear interaction has been a challenge for theoretical physicists. Purpose: In this paper, we propose a methodology based on the reference potential approach for constructing inverse potentials of alpha-alpha scattering. Methods: Two smoothly joined Morse potentials, regular for short-range nuclear interaction and inverted for long range Coulomb, are used in tandem as a reference potential in the phase function method to obtain the scattering phase shifts for the S, D and G states of alpha-alpha scattering. The model parameters are optimized by choosing to minimize the mean absolute percentage error between the obtained and experimental scattering phase shift values. Results: The constructed inverse potentials for S, D and G states have resulted in mean absolute percentage errors of 0.8, 0.5, and 0.4 respectively. The obtained resonances for D and G states closely match the experimental ones. Conclusion: The reference potential approach using a combination of smoothly joined Morse functions is successful in accurately accounting for the Coulomb interaction between charged particles in nuclear scattering studies.Comment: 10 pages, 4 figures, 2 Table

Significance of evaluating mandibular parameters for the identification of an individual

Background: Estimating the age of death is a crucial step since it narrows the field of probable identities that must be compared to remains after mass tragedies. Morphological changes in the mandible are mostly driven by an individual’s age and occlusal status. The aim of this study was to determine the association of the dimensions of these parameters with the age and gender of an individual with a larger sample size using orthopantograms in the north Indian population. Methods: A retrospective radio morphometric analysis was performed for panoramic radiographs of 300 (150 males and 150 females). The digital panoramic images were saved in Dicom format and exported to MicroDicom software for linear measurements. The co-relation of study parameters with age was analyzed by one-way ANOVA and assessment of co-relation with sex by applying student’s t-test. Results: The mean values of the right and left gonial angles were higher in females, while the ramus height and bigonial width dimensions were greater in males. However, only the left gonial angle and ramus height showed statistically significant differences with gender (p<0.05). Conclusions: The present study found substantial changes in gonial angle, ramus height, and bigonial breadth based on gender and age in a larger sample size. As a result, these dimensions can be an accurate predictor of an individual’s age and sex. Thus, morphometric examination of the mandible can be a useful tool in both identifying individuals and studying growth patterns

Diagnostic utility of bone marrow aspiration in bicytopenia

Background: Haematological diseases are frequently seen now a days in different age groups. Patients can present with a variety of presentations in form of cytopenia of a single lineage or in a dual combination or with pancytopenia. Our study focusses on the utility of bone marrow aspiration for diagnosis of bicytopenias by assessment of pattern of bicytopenias in peripheral smear examination. Methods: This was a retrospective study that was conducted over a period of one year in a tertiary care institute of Northern India. Cases of bicytopenia were subjected to bone marrow aspiration and parameters such as cellularity, myeloid to erythroid ratio and cytomorphological details of the cells were documented. Results: Study consisted of male predominance with maximum patients in the age group of 21-30 years. Most common bicytopenia was found to be anaemia with thrombocytopenia and normoblastic erythroid hyperplasia was the most common aetiology.The results of this study were similar to those in the earlier literature with the inference that bone marrow aspiration performed for all cases significantly helped in arriving at the diagnosis. Conclusions: Bicytopenia is a good haematological indicator for many non-malignant and malignant diseases. Knowledge of its aetiologies can help in the diagnosis and efficient management of patients. Bone marrow study forms a cost-effective tool in interpretation of bicytopenia

A STUDY OF SEVERITY OF STROKE AND HOMOCYSTEINE LEVEL IN SOUTHERN PART OF RAJASTHAN, INDIA

Objective: Till date, a very few prospective studies have examined the association between serum homocysteine levels and the risk of stroke and stroke subtypes in Indian populations. Methods: A prospective, case - control study of Indian subjects 10–90 years of age was conducted using frozen serum samples from 103 participants in cardiovascular risk surveys collected from December 2017 to November 2018. By the end of 103, we identified 55 incidents of severe strokes, one control subject per case was selected by matching for sex, age, community, year of serum storage, and fasting status. Serum total homocysteine levels were measured by Cobas c-311. Results: Compared with control subjects, total (n_206), hemorrhagic (n_106), and ischemic (n_87) strokes had higher geometric mean values of total homocysteine and higher proportions of homocysteine −25.0 μ mol/L. Homocysteine was estimated after adjustment for body mass index, smoking, alcohol intake, hypertension, and other cardiovascular risk factors. The excess risk of total and ischemic strokes did not vary significantly according to sex, age, smoking status, or hypertensive status. Conclusion: High total homocysteine concentrations were associated with the increased risk of total stroke, more specifically ischemic stroke) Capsuloganglionic and frontoparietal infarct (8 each)., among Indian men and women

Endophytic microbes modulate plant responses to abiotic stresses: a review

Many groups of microorganisms have been studied for their benefits towards humankind due to their capacity to produce natural compounds that can be valorized in many economic sectors such as agriculture. Due to the extensive use of chemicals pesticides and fertilizers, current agriculture systems facing several major problems such as emergence of resistant in pathogens and pests, soil infertility and bioaccumulation of toxic residues in the environment and particularly in foods which negatively affects human health. The use of natural products harmless to plants, humans and biodegradable constitute a promising way to overcome these problems. Modern agriculture systems are moving toward the use of beneficial microorganisms isolated from the soil, plant surfaces and inside tissues for developing eco-friendly products such as biofertilizers and biopesticides. Recent literatures show that colonization of plants by endophytes is the rule in nature and endophyte-free plant is a rare exception. Endophytes are microbes living inside plant tissues and supporting them in growth and development, as well as stresses tolerance without causing any apparent disease symptom. Abiotic stresses have a great impact on growth, production and health of plants. Many literatures show the role of endophytes in abiotic stress tolerance as well as mechanisms involved to cope with these constraints via the induction of stress-related genes and molecules. This review provides a summary of literature on how endophytes modulate plant growth and responses to abiotic stresses which may help to better understand their role in plant adaptation to environmental constraints and valorize their use in agriculture

A Retrospective Audit of Widal Testing For Enteric Fever in the City Of Ahmedabad

Introduction: Widal test has been used extensively for the sero-diagnosis of Enteric fever in India, however, its accuracy and reliability are debatable. We studied widal testing and widal positivity rates in the entire city of Ahmedabad for the diagnosis of Enteric Fever. Methods We screened all 1700 possible diagnostic laboratory facilities, in Ahmedabad, in the public and private sector. We performed telephonic surveys for the initial filtering of facilities that could be conducting widal testing. It was followed by physical visits to probable facilities to confirm testing methods and preservation of reports of widal testing. We followed a systematic process for screening and selection of 23 laboratories, which conducted widal tests and had reliable data. While 14 laboratories refused to share data, data provided by three of them were inappropriate and couldn’t be used.  We finally analyzed data from four large public hospitals, one private trust hospital and one corporate laboratory for variable periods in a span of 15 years (2000 – 2015). Result: The Widal testing rate was found to be 8.7% and widal positivity as 12.5% in a sample of 1.2 million clinically suspected in-patients. In 15 years, the private hospital had admitted 1/10th as many cases as all the public hospitals together. However, the widal testing and positivity rates were similar in both. We observed a lower proportion of widal positivity among children below 12 years and a disproportionate, but insignificant, gender distribution of widal positivity. Conclusion: This study indicates that the widal test, which is meant to be an initial screening test, is widely used in the city. We propose linkage of testing and reporting of widal with other more reliable and accurate tests such as Typhidot and blood culture in order to strengthen our knowledge of enteric fever epidemiology in India
