RÉSUMÉ

Aim: Salt stress adversely affects plant growth and development. Various mitigating strategies have been employed to enhance the adaptability of plants to salt stress. The present study was conducted with the objective of evaluating the recently developed CO55 rice variety's ability to withstand salt-induced stress during seedling growth. This evaluation included foliar spraying of plant growth promoting substances like melatonin, salicylic acid, silicon, and selenium, along with the identification of effective plant growth-promoting substances that exhibit tolerance to salinity. This study is required to develop salt-tolerant varieties capable of withstanding salinity stress during the seedling stage. The seedling stage is more susceptible to salinity, and also to increase the growth and yield of rice, thereby satisfying the country's agricultural needs.Study Design: Completely randomized design.Place and Duration of Study: Department of Crop Physiology, Tamil Nadu Agricultural University, Coimbatore; March-April 2023.Methodology: In the hydroponics experiment, the CO55 rice variety was subjected to foliar spraying of various plant growth promoting substances such as melatonin, salicylic acid, orthosilicic acid, and sodium selenate. Parameters like leaf drying score, osmotic potential, osmotic adjustment, sodium content, potassium content, and Na+/K+ ratio were assessed. One-way ANOVA was used to analyze the data.Results: Specific pairwise differences between means were assessed at the 0.05 significance level using Fisher's least significant difference (LSD) test. Among the treatments applied, salicylic acid recorded the highest potassium content (3.94%), and the lowest potassium content (2.60%) was found in orthosilicic acid. On the other hand, from the standard evaluation score, it was observed that CO55 rice variety seedlings were found to be tolerant when treated with salicylic acid, whereas it was susceptible under orthosilicic acid treatment.Conclusion: Observations indicated that foliar application of salicylic acid at the concentrations of 50µM and 100µM exhibited higher tolerance towards salinity during the seedling growth stages.

RÉSUMÉ

Objective: It was investigated to enlighten the phytochemical screening and antihyperlipidemic activity of seeds of Canavalia ensiformis (L.) in High fat diet Streptozotocin-induced diabetic rats. Methods: The ethanolic seed extract of Canavalia ensiformis (EECE) at a dose of 400 mg/kg and 200 mg/kg was administered to diabetic rats. Simvastatin (4 mg/kg) is used as a standard drug. Results: The statistics were assessed by using one way ANOVA followed by Dunnet’s multiple comparison tests. To unfold the mechanism we studied all the biochemical parameters like Total cholesterol (TC), Triglycerides (TG), high-density lipoproteins (HDL), low-density lipoproteins (LDL) and histopathological examination of Liver tissue section. The ethanolic extracts of seeds of Canavalia ensiformis showed significant reduce of the level of cholesterol, triglycerides, LDL, VLDL and a significant increase in the serum level of HDL at 400 mg/kg rather than 200 mg/kg. Conclusion: Further the characterization and isolation of the constituents could be done to know the exact mechanism of hyperlipidemic activity. Statistical analysis of this screening method conforms that the proposed method is appropriate and it can be useful, gives the basic idea to the researcher who is working in an area like Antihyperlipidemic activity.

RÉSUMÉ

Dipeptidyl peptidase (DPP)-IV inhibitors are a new approach to the treatment of type 2 diabetes. DPP-IV is a member of a family of serine peptidases that includes quiescent cell proline dipeptidase (QPP), DPP8, and DPP9. DPP-IV is a key regulator of incretin hormones, but the functions of other family members are unknown. To determine the importance of selective DPP-IV inhibition for the treatment of diabetes, we conducted molecular docking studies on clinical inhibitors of DPP-IV.

RÉSUMÉ

The most challenging and appreciated area in the field of Prosthodontics is the rehabilitation of maxillary defects. Tumors of the head and neck are the common cause for acquired maxillofacial defects. Surgical consequences predispose the patient to hypernasal speech, fluid leakage into nasal cavity, impaired masticatory function, and cosmetic deformity. The Prosthodontists play a significant role in the intervention and improve the quality of life of such patients. The current article describes two clinical case reports of completely edentulous patients with acquired maxillary defects.
