Suitability of Killai backwaters for prawn farming-a preliminary micro level survey

Brackishwater areas have been given much importance for prawn farming. No information was available on the Killai backwaters about factors like water quality, topography, contour, extent of the area, tidal amplitude, seed potential and possibilities of flooding etc. Hence during 1982-'84 Klllai area was thoroughly surveyed on the above aspects and the results have been discussed in this paper. From this it is inferred that a total area of about 155 ha is readily available for undertaking both pond and pen culture in this backwater

CARDIOVASCULAR DISEASES ASSOCIATED WITH PSEUDOEXFOLIATION SYNDROME – A PROSPECTIVE CROSS-SECTIONAL STUDY

Objectives: In recent years, pseudoexfoliation syndrome (PXF) is recognized as a systemic disorder and as an independent risk factor for cardiovascular diseases including hypertension, angina, myocardial infarction, and stroke. We studied the prevalence of cardiovascular diseases associated in patients with PXF. Methods: It was a prospective cross-sectional study done over a period of 2 years from January 2017 to December 2018 at the Department of Ophthalmology in Sree Balaji Medical College and Hospital. A total of 100 patients with PXF both male and female above the age of 50 were included in the study. They were given a standard questionnaire to evaluate common cyclic vomiting syndrome symptoms and a history of angina, myocardial infarction, and cerebrovascular accident was noted. All patients underwent blood pressure (BP) measurement and electrocardiogram (ECG) recording. Results: In our study which included 100 patients with PXF there were 57 male patients and 43 female patients. Most of the patients (59%) were above 65 years of age and 36 patients were diagnosed with open-angle glaucoma. A total of 62 patients had persistently elevated BP on three different occasions. Only five patients gave a positive history of angina at some point in their lives and among them, only four patients showed demonstrable changes in ECG. One patient gave a history of myocardial infarction (two showed changes in ECG) and none of the patients had cerebrovascular accidents. Conclusion: Our study showed that more than 60% of patients with PXF had hypertension; however, a statistically significant association with other conditions was not noted

Nutritional Analysis of Mature Unripen and Ripen Edible Fruits of Aegle tamilnadensis Abdul Kader (Rutaceae)

Nutritive analysis of mature unripe and ripe fruits of Aegle tamilnadensis which is a close relative of A. marmelos (L) Correa was carried out at Presidency College, Chennai during 2016. Mature unripen fruits were plucked from the tree while ripen fruits were gathered from the ground after their natural fall during the month of December 2016 from the campus of Govt. Siddha Medical College, Arumbakkam, Chennai, Tamil Nadu, India. Seeds were removed; fresh fruit pulp was collected and weighed. Such pulp was used for the extraction of nutrients using methanol in Soxtron apparatus (Socs Plus - SCS 06 E). The moisture content was estimated by hot air oven method and expressed on dry weight basis [10]. The methanol fruit pulp extracts were used with standard methods for the estimation of protein, carbohydrate (sugar), energy, fat, vitamins, and minerals such as calcium, sodium and iron. The results showed that the mature unripe fruit contain high protein, sodium and calcium contents while cholesterol and fat contents were lower than those present in the ripe fruits. On the contrary in ripe fruit, vitamin C and iron contents were high. Therefore, both mature unripe and ripe fruits of Aegle tamilnadensis Abdul Kader can be used as a potential natural nutraceutical

SARS-CoV-2 seroprevalence among the general population and healthcare workers in India, December 2020–January 2021

Background: Earlier serosurveys in India revealed seroprevalence of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) of 0.73% in May–June 2020 and 7.1% in August–September 2020. A third serosurvey was conducted between December 2020 and January 2021 to estimate the seroprevalence of SARS-CoV-2 infection among the general population and healthcare workers (HCWs) in India. Methods: The third serosurvey was conducted in the same 70 districts as the first and second serosurveys. For each district, at least 400 individuals aged ≥10 years from the general population and 100 HCWs from subdistrict-level health facilities were enrolled. Serum samples from the general population were tested for the presence of immunoglobulin G (IgG) antibodies against the nucleocapsid (N) and spike (S1-RBD) proteins of SARS-CoV-2, whereas serum samples from HCWs were tested for anti-S1-RBD. Weighted seroprevalence adjusted for assay characteristics was estimated. Results: Of the 28,598 serum samples from the general population, 4585 (16%) had IgG antibodies against the N protein, 6647 (23.2%) had IgG antibodies against the S1-RBD protein, and 7436 (26%) had IgG antibodies against either the N protein or the S1-RBD protein. Weighted and assay-characteristic-adjusted seroprevalence against either of the antibodies was 24.1% [95% confidence interval (CI) 23.0–25.3%]. Among 7385 HCWs, the seroprevalence of anti-S1-RBD IgG antibodies was 25.6% (95% CI 23.5–27.8%). Conclusions: Nearly one in four individuals aged ≥10 years from the general population as well as HCWs in India had been exposed to SARS-CoV-2 by December 2020
