Galactinol synthase 4 requires sulfur assimilation pathway to provide tolerance towards arsenic stress under limiting sulphur condition in Arabidopsis.

Heavy metalloid stress such as arsenic (As) toxicity and nutrient imbalance constitute a significant threat to plant productivity and development. Plants produce sulfur (S)-rich molecules like glutathione (GSH) to detoxify arsenic, but sulfur deficiency worsens its impact. Previous research identified Arabidopsis thaliana ecotypes Koz2-2 (tolerant) and Ri-0 (sensitive) under low-sulfur (LS) and As(III) stress.

Ethylene regulates miRNA-mediated lignin biosynthesis and leaf serration in Arabidopsis thaliana.

microRNAs (miRNAs) regulate target gene expression by pairing to target mRNAs, leading to mRNA degradation or translation inhibition. Out of several miRNAs in Arabidopsis, miR397b and miR857 regulate secondary growth by modulating lignin polymerization and deposition in secondary xylem cells by targeting laccases. Interestingly, the phytohormone ethylene is also suggested to have a role in lignin biosynthesis in tension wood formation.

Clinical and Radiographic Analysis of Novabone Putty with Platelet-Rich Fibrin in the Treatment of Periodontal Intrabony Defects: A Randomized Control Trial.

Background: Periodontal regeneration remains one of the crucial issues in the field of periodontology. Periodontal intrabony defects could be treated by surgical intervention through various alloplastic bone graft substitutes. The Food and Drug Administration approved, Novabone putty is one of the recently marketed bone graft substitutes, which has been used in the present study.

Light-regulated expression of terpene synthase gene, AtTPS03, is controlled by the bZIP transcription factor, HY5, in Arabidopsis thaliana.

The terpenoid pathway serves as an essential source of all isoprenoid precursors and metabolites that are of great pharmacological importance. The major enzymes for the synthesis of these diverse molecules is the terpene synthases (TPSs), which catalyse the final step of the synthesis of the important secondary products, the terpenes. Previous studies have reported that the various environmental factors, including light govern the synthesis of terpenoids.

Role of 0.5 M mannitol as an adjuvant with lidocaine with or without epinephrine for inferior alveolar nerve block: A randomized control trial.

Background: The most commonly used local anesthetic in dentistry is lidocaine. For decades, mannitol is the most widely used agent in the management of raised intracranial pressure and as prophylaxis against acute renal failure surgeries.

Material And Methods: 120 patients were randomly divided into four groups, 30 patients in each group.
