The Principles of Kurinjithinai in Agathinai

Thinai refers to the land, which is the primary object and the focus of the activities of the people. In addition to stating the governance details and material conditions, it also categorizes the objects and gives explanations accordingly. It will classify how literary material is situated, and the race will separate and specify its meanings. The study of Kurinjithinai theory has briefly examined the Thinai, the doctrines of the Thinai, the history of the Kurinji land, the reasons for the names, the hill stations, and the first theme, the theme, etc. In this, the information about Thinai is clearly mentioned. The names of the hill land and the land of Kurinji are mentioned in detail. In addition, the article contains the principles of the life of the ancient Tamils, such as the Mutharporul (five elements and time), the Karupporul (fourteen subject matters that include God), and the Uripporul (morals performed by people). Therefore, it clearly mentions the information about Thinai

Effect of organic and inorganic nutrients on rice (Oryza sativa var. CO 51) productivity and soil fertility in the Western zone of Tamil Nadu, India

In sustainable agriculture, to ensure high-quality food production, a combination of organic and inorganic nutrient sources are required. During the winter season of 2020, a field experiment was undertaken in the western zone of Tamil Nadu to assess the effects of organics and inorganics on the growth, yield, and soil properties of rice, Oryza sativa var. CO 51. The experiment was framed in Random Block Design (RBD) comprising of 8 treatments viz., Recommended dose of fertilizer Soil Test Crop Response (STCR) approach (T1), RDF 75 % + Farm yard manure @ 12.5 t ha-1 (T2), T2 + Seed treatment with Azospirillum and Phosphobacteria + Soil application of AM fungi (T3), RDF 75 % + Vermicompost @ 5 t ha-1 (T4), T4 + Seed treatment with Azospirillum and Phosphobacteria + Soil application of AM fungi (T5), FYM @ 12.5 t ha-1 + Seed treatment with Azospirillum and Phosphobacteria + Soil application of AM fungi (T6), Vermicompost @ 5 t ha-1+ Seed treatment with Azospirillum and Phosphobacteria + Soil application of AM fungi (T7) and absolute control (T8) , replicated thrice. Among the integrated nutrient management practices, T5 proved its superiority over other treatments with respect to growth and physiological parameters followed by T3. This would have been because of the solubilization of phosphorus in the soil by AM organisms which is made accessible for crop growth. Utilization of biofertilizer enhanced the N availability and solubilized the inaccessible phosphorus, which thus recorded higher N accessibility and better phosphorus uptake when applied along with a recommended dose of fertilizer for rice.

Impact of perioperative period on disease-free survival among carcinoma ovary patients treated with the interval cyto-reductive surgery at a tertiary cancer centre in Kerala, India: a retrospective study

Background: Global incidence of ovarian malignancies is 300,000 as per GLOBOCAN 2018. The treatment protocol for advanced ovarian malignancies (stage IIIc and stage IV) includes neo-adjuvant chemotherapy and surgery followed by adjuvant chemotherapy. Aims of the study was to determine the effect of duration of chemo interruption on disease free survival of ovarian malignancies treated by interval cytoreduction followed by surgery.Methods: A total 48 patients were studied for events such as recurrence, death, patient’s status on last follow up, peri-operative period between 3rd cycle of chemo therapy and 4th cycle of chemo therapy. Based on the median duration of peri operative period patients was classified as early or delayed receivers of adjuvant chemo therapy. Difference in duration of over-all survival and disease-free survival was analysed through Kaplan Meier survival analysis using log-rank test. Hazard ratio adjusted for background characteristics such as staging, performance status, grade of tumour were analysed using cox proportional hazard model.Results: The two peri operative period categories based on mean value (85 days) didn’t show any significant association to disease free interval (minimum-21days, maximum-146 days, Hr = 1.3, p-value = 0.52). Other established factors like stage, extent of resection, response to chemotherapy, also didn’t show any significant association. Serum marker level showed a significant negative correlation with disease free survival (minimum-9 days, maximum-30659, p-value =.04, Hr = 3.19).Conclusions: The study could not establish any correlation between peri operative period and median disease-free survival. The small sample size is a limiting factor, well controlled randomized trials may needed for further clarification

Estimation of repeatability and phenotypic correlation of reproductive traits in zebrafish Danio rerio

This study was conducted to estimate the repeatability and phenotypic correlation of reproductive traits of zebrafish Danio rerio, in captive condition. Breeding trials were conducted on 10 breeding pairs (2 male:1 female). The data on fecundity, fertility, hatchability and survival rate were recorded. The repeatability values were computed as a measure of consistency using the intra-class correlation coefficient. The repeatability estimates for fecundity, fertility, hatchability of total eggs, hatchability of fertilised eggs, survival rate of total eggs and survival rate of larvae were 0.701, 0.406, 0.336, 0.049, 0.295 and 0.314, respectively. Most of the reproductive traits analysed had moderate repeatability values barring the hatchability of fertilised eggs. The phenotypic correlation was calculated using the Pearson correlation method. The phenotypic correlations of fertility with hatchability of fertilised eggs; hatchability of total eggs; survival rate of total eggs and survival rate of larvae were highly significant (p≤0.01). This study provided valuable information on the consistency of reproductive parameters which would serve as model for conducting research in other fish species

Cytotoxic effect of crude venom isolated from Sea anemone Calliactis tricolor on human cancer cell lines

601-609The present study was made to analyze the antiproliferative effect of crude venom isolated from sea anemone Calliactis tricolor against human cancer cell lines such as Human Neuroblastoma cell (SHSY5Y), Human Lung Cancer cells (A549) and Human Colon Cancer cells (HT-29). The protein profile of venom was performed by Native PAGE and subunit profile was analyzed by SDS-PAGE. The in vitro cytotoxic effect of crude venom against SHSY5Y, A549, HT-29 and Vero cell lines was evaluated by MTT assay method. All the cells exposed to crude venom showed dose-dependent cytotoxic effect with IC50 of 60 µg/ml for both SHSY5Y and A549 cells and 75 µg/ml for HT-29 cells compared to with IC50 of 100 µg/ml for the Vero cell control. The significant decrease in cell viability was observed in SHSY5Y Human Neuroblastoma cells among other cancer cells. The cellular and nuclear morphological observations revealed the loss of cell morphological integrity along with the prominent damage of nucleus in the cell. This was further confirmed by DNA fragmentation assay. Based on the preliminary results, it could be clearly stated that the crude venom of C. tricolor may have a potential anti-cancerous molecules which can be further explored and used as a tool for Neuroblastoma chemotherapy. 

Endocrine Autoimmunity in Association with Female Infertility

Infertility is the inability to conceive after a year of regular unprotected sexual intercourse, affecting 10-15% of couples. Advanced age, obesity, and certain medications can hinder fertility. Endocrine autoimmunity is increasingly recognized as a significant contributor to female infertility, often complicating various gynecological conditions. Autoimmune issues involving the hypothalamus, pituitary gland, thyroid, adrenal glands, and ovaries can impact fertility. A multidisciplinary approach is essential for diagnosing infertility, with a crucial focus on identifying potential endocrine disorders. Here we discuss how to identify endocrine autoimmune patients with ovulatory dysfunction. Women must be advised about limiting factors to be avoided, to protect their fertility. A comprehensive understanding of the underlying mechanisms, coupled with appropriate diagnostic and therapeutic approaches, is crucial for effectively managing this complex condition and helping women achieve their reproductive goals
