Development and Rapid Intensification of Tropical Cyclone OCKHI (2017) over the North Indian Ocean

Tropical Cyclone OCKHI over the North Indian Ocean during 2017 underwent dramatic development and rapid intensification very close to the land - Sri Lanka, extreme South Indian coast and Lakshadweep area during its initial developmental stage and caused extensive damages over these areas. On examining the physical and structural mechanism involved in such development, it is observed that the initial development was associated with axi-symmetrisation of the vortex that could be associated with Vortex Rossby waves near the eyewall. Associated with the expulsion of high vorticity from the centre during asymmetry mixing, there was outward propagation of eddy angular momentum flux in the lower levels that strengthened a low level anticyclone to the northeast of the TC centre which in turn enhanced the cyclonic inflow near the TC centre. The rapid intensification phase was associated with vertical non-uniform heating with upper and lower tropospheric warming associated with latent heat release in convection. During the mature phase, the system sustained ‘very severe’ intensity even under increasing vertical shear and lower ocean heat flux under the influence of a break in the sub tropical ridge to the north of the system centre that enhanced the poleward outflow in the upper troposphere

Effect Of Alloxan Mixed Diet On Blood Parameters And Its Management By Silkworm Pupae Meal Diet In Common Carp

This paper presents a brief overview on the entry of alloxan into foods and its fatal link to blood parameter in carp. The management of silkworm pupae meal diet induced Alloxan blood parameter in carp. Five series of experiments were conducted to investigate the induced alloxan on blood parameter studied In the 8th series of experiments, utilization of Silkworm pupae meal diets on the reduction of alloxan toxicity on blood parameter, were estimated. The increase in the levels of alloxan decreases the Hb and RBC level where as WBC, Esr and Ht increases during the exposure period. Then treatment with silkworm pupae meal diet there an opposite trend was obtained. The administration of silkworm pupae meal might be beneficial for the restoration of hematological parameters, in the present study have revealed that incorporate silkworm pupae meal diet reduced the blood nonfunctional plasma enzymes and liver function parameters in Alloxan induced hyperglycemia in common carp. On the other hand Alloxan-induced diabetes could increase the liver enzyme levels. The increase in these enzymes may occur due to peroxidation reactions, arising from Alloxan biotransformation during diabetes and these reactions may inflict oxidative injury to cellular components. Our data shows that the silkworm is a good edible resource of natural Silkworm pupae meal diet with hypoglycemic activity which retards the ill effect of alloxan induced hyperglycemia

To Determine The Acute Toxicity Pesticide Of Malathion And Metabolic Activities And Respiratory Responses In Freshwater Fish Labeo Rohita

The water pollution of aquatic environment with wide array of pesticides has become a menace to the aquatic flora and fauna. The organophosphorus pesticide malathion has been widely used in agriculture for several crops such as paddy, cotton and vegetables to control serious insects and mites. These chemicals cause severe damage to aquatic ecosystem especially to fishes. The main aim and objective of present study is to evaluate the impact on protein and glycogen in fingerlings of Labeo rohita an economically important Indian major carp. The 96 hrs LC50 value of malathion for L.rohita was 9.0 ml/L. No mortality was observed below the concentration of 7.5 ml/L. The changes in biochemical parameters such as protein and glycogen are important to indicate the susceptibility of organs system to pollutants by altering their function. In the present investigation the protein and glycogen contents of muscles, gills, liver, kidney and brain of L.rohita were analysed. Fish reared in control group registered high protein and glycogen contents when compared with malathion treated groups during 24, 48, 72 and 96 hrs respectively. The similar results were obtained in the oxygen consumption of L.rohita during 24, 48, 72 and 96 hrs respectively It is concluded that malathion concentrations (low and high) is very toxic and causes alterations in vital organs of fish L. rohita

Evaluation of safety, efficacy, acceptance and expulsion of post placental intrauterine contraceptive device in a tertiary care centre

Background: Postpartum intrauterine device provides an effective temporary method of contraception for the woman who needs birth spacing rather than birth limitation and also a quasi-permanent family planning method. The aim of this study was to study the efficacy, acceptance, safety and complication of PPIUCD insertion.Method: This a retrospective analytical study done in a tertiary care teaching institute, Institute of Obstetrics and Gynaecology Egmore for a six-year period from January 2010 to December 2015 with a sample size of 81204. Outcomes measured were safety, efficacy, acceptance (patients and professionals) and complications.Results: For the study period of six years the total number of women delivered were 81204. A steady increase was noted in the insertion of PPIUCD from 2010 (1.98%) to 2015 (58%). 50.5% had insertion following caesarean section and 49.5% following vaginal delivery. Primipara had a higher rate of acceptance amounting to 74.74%. Most common complication reported was missing strings 9.25% and a greater part of the patients (83%) did not have any complaints.Conclusions: Enthusiasm and conviction on the part of the health care provider goes a long way in improving the acceptance rate of PPIUCD. It is an indispensable contraceptive tool for our country since our women most often do not return for postnatal contraceptive options

Effect of short-term naturopathy and yoga intervention on anthropometric variables, lipid profile and thyroid profile in obese hypothyroid patients: a randomised controlled trial

Background: Hypothyroidism reflects decreased thyroid function and is one of the most common conditions seen in clinical practice. Practice of naturopathy and yoga has shown improvement in anthropometric variables and lipid profile in obesity and other chronic diseases. So, the aim of this study was to find out the effect of naturopathy and yoga in obese hypothyroid patients.Methods: A total of 60 subjects, of which 29 males (age 44.2±7.0 years) and 31 females (age 40.6±7.4 years) with body mass index (BMI), ≥30 were randomly assigned to case group (n=30) and wait list control group (n=30). The subjects of case group underwent naturopathy and yoga intervention for 10 days. Anthropometric variables, viz., body weight, BMI, waist circumference (WC) and hip circumference, serum lipid profile, and serum thyroid profile were assessed at 1st day (pre), at the end of 10 day (post).Results: The result showed a significant reduction in body weight, BMI, WC, total cholesterol, low density lipoprotein-cholesterol (LDL-C) and thyroid stimulating hormone (TSH) along with significant improvement in high density lipoprotein-cholesterol (HDL-C) in case group compared with control group in independent samples t test. Significant reduction in body weight, BMI, total cholesterol, LDL-C and TSH were observed in case group unlike in control group in student's paired t test.Conclusions: Reduction in the body weight, BMI and improvement in serum lipid profile and serum thyroid profile in case group subjects compared to control group suggest that naturopathy and yoga have therapeutic and protective effects in the management of obese hypothyroid patients

Understanding the etiopathogenesis of Uttana Vatarakta (peripheral vascular disease) - An Observational Study

Advanced life style and changing food habits affects the activities of individual which leads to many diseases and Peripheral Vascular Diseases are one among them. They are characterized by reduction of blood flow and oxygen supply through peripheral vascular vessels. This can happen in arteries or veins. The incidence of Varicose vein is more common with age and high prevalence is after 30 years of life. PAD occurs in patients over 40 years old; the highest incidence occurs in the sixth and seventh decades of life and it affects 10-15% of the general population. The symptoms of Uttana Vatarakta owing to the Margavarana pathology simulate with the symptoms of Peripheral vascular diseases and some of the etiological factors of Uttana Vatarakta in the writing are specific in inclining Peripheral Vascular Diseases. Ayurveda emphasise the importance of study on etiopathogenesis of disease before the planning of treatment protocol. In this study an effort is done to identify the Nidanas and pattern of Samprapti in relation with Peripheral vascular diseases for the better understanding of different clinical presentations of Uttana Vatarakta

An observational study to explore the Samprapti Ghatakas in Hypothyroidism

Background: Hypothyroidism is the most common functional disorder of the thyroid gland. It is a hypometabolic clinical state resulting from inadequate production of thyroid hormones for prolonged periods. The prevalence of this disease in India is 6% and more than 10 million cases per year are reported. It is a multisystemic disorder which has a wide range of clinical symptoms. This condition is not mentioned in Ayurveda classics by any specified name. In Ayurveda, determining the elements that contribute to Samprapti is essential in developing a treatment plan. Hence, the current study attempts to evaluate the Samprapti Ghatakas and as a result, formulate probable Samprapti. Objectives: To study and explore the Samprapti Ghatakas of hypothyroidism and to propose possible Samprapti. Methods: The study was conducted in 100 cases of hypothyroidism between the age of 16 to 70 years. A case proforma was prepared which includes history taking, physical signs and symptoms and required examination. The calculations were done in Microsoft excel and the values obtained were assessed on the basis of percentage of individual parameters in relation with Samprapti Ghatakas of hypothyroidism. Results: Kapha and Vata are the main Doshas involved in the Samprapti. Important Dooshyas are Rasa, Meda. Agni involved is Dhatwagni and the disease is caused primarily due to Dhatwagnimandya. Udakavaha, Annavaha, Medovaha, Swedavaha, Purishavaha, Rasavaha are the main Srotas involved with Sanga type of Srotodushti. Udbhava Sthana can be considered as Amashaya; Sanchara Sthana, Vyakta Sthana and Adhishtana is Sarva Shareera. All the three Rogamarga are involved

Tunability of the spin reorientation transitions with pressure in NdCo5

We present pressure-dependent magnetization measurements carried out in the domain of the spin reorientation transitions (SRTs) of a NdCo5 single crystal. The application of a hydrostatic pressure leads to a shift in the SRTs to higher temperatures. This shift is found to be very sensitive to pressure, with the SRT temperatures increasing at a rate of ≈17 K/GPa. To explain the experimental results, we have also performed first-principles calculations of the SRT temperatures for different applied strains, which corroborate the experimental findings. The calculations attribute the pressure dependence of the SRTs to a faster weakening of the Co contribution to the magnetocrystalline anisotropy with pressure compared to the Nd contribution

ALTERATIONS OF LIPID PROFILE LEVELS IN 7,12-DIMETHYLBENZ(A)ANTHRACENE INDUCED ULCERATIVE COLITIS RAT MODEL

Objective: Ulcerative colitis is a type of inflammatory bowel disease is a chronic gastrointestinal disorder characterized by intestinal inflammation and mucosal tissue damage. We examined the lipid profile levels in murine model of 7,12 Dimethylbenz(a)anthracene induced ulcerative colitis.Methods: Serum was separated from whole blood and was used to determine the lipid profile such as total cholesterol (TC), phospholipids (PL), triglycerides (TG), free fatty acids, high density lipoprotein (HDL-C) and low density lipoprotein (HDL-C).Results: Ulcerative colitis rats exhibit low level of low density lipoprotein cholesterol and total cholesterol. No significant difference was observed in high density lipoprotein and triglycerides and significant difference was observed in phospholipids and free fatty acid serum levels. This communication highlights the lipid profile that occurs in ulcerative colitis.Conclusion: This study, thus, provides valuable information about the disturbances in the lipids and lipoproteins occur in ulcerative colitis.Keywords: Ulcerative colitis, 7,12-Dimethylbenz(a)anthracene, Lipoprotein, Low-density lipoprotein, Phospholipids
