Toxicological evaluation of a nonlethal riot control combinational formulation upon dermal application using animal models.

Numerous adverse effects on human health have been reported in epidemiological studies of oleoresin capsicum (OC) and other riot control agents (RCAs). Importantly, the daunting risk of such RCAs can be neutralized by optimizing the desired concentration of such agents for mob dispersal. Hence, a nonlethal riot control combinational formulation (NCF) was prepared for dispersing rioters without imparting fatal outcomes.

Evaluation of water quality index and geochemical characteristics of surfacewater from Tawang India.

In this study,the water samples were collected from 31 sites of Tawang, Arunachal Pradesh, India (North-Eastern Himalaya), during the winter season to check the suitability of water for drinking and irrigation purposes.The study scientifically demonstrates the estimation of Water quality index (WQI) andhydrogeochemical characteristics of surface water samples by utilizing multivariate statistical methods. The main water quality parameters considered for this study were TDS, conductivity, salinity, pH, hardness, cations and anions.

Exploring the frostbite healing potential of hyaluronic acid based hydrogel of Manuka honey through antithrombotic and anti-platelet studies of major phytoconstituents and evaluation in Wistar rat model.

Objective: Development of Frostbite healing hydrogel of Manuka honey and hyaluronic acid.

Significance: Frostbite is a cold-induced ischemic vascular injury non-responsive to most of the wound healing products. Thrombus-induced ischemia is the main cause of frostbite-related necrosis.

Frostbite: Current status and advancements in therapeutics.

Frostbite is a severe ischemic injury which occurs due to the tissue vascular damage after sub-zero temperature tissue exposure. Deep frostbite can result in necrosis and may need amputation of affected tissue. Though a serious injury, it is not very well understood, and further scientific exploration is needed.

Innate inflammatory response to acute inhalation exposure of riot control agent oleoresin capsicum in female rats: An interplay between neutrophil mobilization and inflammatory markers.

The use of oleoresin capsicum (OC) sprays, due to their irreversible health effects has now grown into a matter of heated debate. In the present study, the early phase pulmonary events involving chemotactic and inflammatory mediators after short-exposure duration to OC have been presented. Female Wistar rats used in the evaluation of respiratory parameters at 1 h, 3 h, and 24 h post-exposure, were sacrificed for the evaluation of blood cell counts, BALF cytokine estimation, lung capillary leakage, study of oxidative stress and histopathology of the lungs.

Formulation development and accelerated stability testing of a novel sunscreen cream for ultraviolet radiation protection in high altitude areas.

The present study is aimed at the development of a sunscreen cream for use in high altitude areas which have been found to possess superior sun protection factor (SPF) along with remarkable antioxidant activity. The topical formulation is a standard oil-in-water emulsion of a combination of United States Food and Drug Administration (US FDA) approved ultraviolet filters; along with melatonin and pumpkin seed oil. The in-silico optimized formulation was characterized using established methods and the stability study was carried out as per International Conference on Harmonization guidelines.

Amelioration of UV radiation-induced photoaging by a combinational sunscreen formulation via aversion of oxidative collagen degradation and promotion of TGF-β-Smad-mediated collagen production.

The presence of 40-50% more UV radiation in high altitude areas renders the plethora of sunscreen products available in the market virtually ineffective. In this light of event, four US FDA approved UV filters were combined with melatonin and pumpkin seed oil to produce a broad spectrum sunscreen cream, which is envisaged to provide optimum sunprotection along with enhanced antioxidant activity. The objective of this study is to evaluate the protective effect of the sunscreen cream against UV radiation-induced skin photoaging in adult Wistar albino rats and identify its possible underlying mechanism.
