β-Caryophyllene attenuates oxidative stress and inflammatory response in LPS induced acute lung injury by targeting ACE2/MasR and Nrf2/HO-1/NF-κB axis.

Acute lung injury (ALI) and its severe form, acute respiratory distress syndrome (ARDS), is a clinical syndrome that can cause pulmonary edema, inflammation, oxidative stress, and immunological dysregulations. β-Caryophyllene (BCP), a natural bicyclic sesquiterpene, possesses a variety of pharmacological properties and has the potential to be a therapeutic agent. This study aimed to comprehend the effect of BCP on Nrf2/HO-1/NF-κB and ACE2/MasR axis in a rat model of ALI by lipopolysaccharide (LPS) and the underlying mechanisms during this process.

Amelioration from the ocular irritant Capsaicin: development and assessment of a Capsazepine gel system for ocular delivery.

Background: Defense personnel utilize capsaicin-based ocular sprays as non-lethal agents for law implementation during instances of mob violence. This study involves the capsaicin antagonist Capsazepine and the investigation of whether Capsazepine's antagonistic approach can be favorably utilized for defense utilization to block capsaicin-initiated pain and inflammation via the ocular pathway.

Research Design And Methods: Ocular capsazepine gels were prepared with polymers Pluronic F-127 and Chitosan; optimized formulation was quantified in ocular tissues chromatographically and by live ocular imaging; anti-inflammatory efficacy was determined by eye irritation testing, corneal and retinal imaging, ocular prostaglandin estimation, and by viability and proliferation testing using human ocular cell lines, etc.

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.

Prophylactic efficacy of some chemoprotectants against abrin induced lethality.

Abrin is a highly toxic protein produced by . Exposure to abrin, either through accident or by act of terrorism, poses a significant risk to human health and safety. Abrin functions as a ribosome-inactivating protein by depurinating the 28S rRNA and inhibits protein synthesis.

Acute and sub-acute toxicity of an insect pheromone, N-heneicosane and combination with insect growth regulator, diflubenzuron, for establishing no observed adverse effect level (NOAEL).

Aedes aegypti mosquito is one of the most notorious vectors of dangerous diseases like dengue hemorrhagic fever and chikangunya. One method of control of the vectors is by the use of semiochemicals or pheromones. The pheromone n-heneicosane (C21) has been proved to be effective in attracting the female Aedes aegypti to lay eggs in the treated water and the growth of the larva is controlled by insect growth regulator diflubenzuron (DB).

Analgesic and anti-inflammatory activity of amifostine, DRDE-07, and their analogs, in mice.

Objectives: To find out the analgesic and anti-inflammatory activity, if any, of Amifostine [S-2(3 amino propyl amino) ethyl phosphorothioate], DRDE-07 [S-2(3 amino ethyl amino) ethyl phenyl sulphide] and their analogs DRDE-30 and DRDE-35, the probable prophylactic agent for sulphur mustard (SM).

Materials And Methods: In order to find out the analgesic activities of the compounds two methods were employed, namely, acetic acid-induced writhing test and formalin-induced paw licking. The persistent pain model of formalin-induced hind paw licking was carried out to test the effect of the compounds on neurogenic pain or early phase (0 to 5 minutes) and on the peripheral pain or the late phase (15 to 30 minutes).
