Summary: Several studies have shown that pesticides have the most oxidative impact in rural areas where they are heavily used. Pyrethroids can promote neurodegeneration, oxidative stress, mitochondrial impairments, a-synuclein overexpression, and neuronal cell loss. This study evaluated the effects of early-life exposure to a commercial formulation containing deltamethrin and cypermethrin on brain antioxidant activity and a-synuclein levels in rats. The results showed increased antioxidant levels in the brain regions, reduced striatal a-synuclein expression, and potential adaptive responses.

Summary: Melatonin treatment through seed priming and foliar application improved the growth, physiological, and biochemical traits of pearl millet under drought stress. It regulated the expression of antioxidant-responsive genes, increased proline content, and reduced oxidative damage. The activities of antioxidant enzymes were also enhanced. Seed priming at 120 mu M and foliar application at 160 mu M were particularly effective.

Summary: This study aimed to investigate the activity of several enzymes related to oxidative stress and the concentration of glutathione in the circadian rhythm. The results showed that the activity of these enzymes and the concentration of glutathione peaked at 2 a.m. during sleep. This suggests that the processes maintaining the redox balance are intensified during sleep, thus reducing oxidative stress.

Summary: Melatonin protects plants from heavy metal stress by immobilizing the metals in cell walls and storing them in root cell vacuoles, reducing their translocation to shoots. It enhances osmolyte production, increases antioxidant enzyme activity, and improves photosynthesis, thereby improving cellular functions. Understanding melatonin-mediated response and signaling is important for sustaining crop production in heavy metal-stressed soils.

Summary: Entomopathogenic nematodes (EPNs) are effective biopesticides used in insect control, but their low popularity is due to the reduced infectivity caused by periodic release of stored EPNs. This study focuses on storing EPNs for a longer period of time using encapsulating beads. The results show that Arabic gum-sodium alginate combination is a promising approach and semi-field trials proved the efficacy of storing encapsulated EPNs in mosquito larval control.

Summary: In this study, bioactive compounds from Penicillium sp. were isolated and tested for insecticidal activity on Spodoptera litura and Culex quinquefasciatus larvae. Functional groups such as chloroalkanes, sulfonates, phosphines, amines, carboxylic acid, alkanes, and isocyanates were identified by FTIR. Ethyl acetate extract of Penicillium sp. showed significant larvicidal activity and high antifeedant activity against the larvae.

Summary: Black pepper, known as black gold, has been traded like gold in the past. The market value of black pepper is determined by its color, lustre, and density. Sun-drying is a common drying method, but it affects the shiny black color. Blanching is one technique to retain the color but requires extra time and resources. An experiment was conducted to find an alternative method to retain the black color without affecting quality, and covering the berries with a 100-gauge polythene sheet for 3 or 5 hours and subsequent drying under direct sunlight proved to be effective.

Summary: In this study, immune-related proteins were identified in the larval hemolymph of Spodoptera litura after Bacillus thuringiensis bacterial challenge. The high expression of immune defense protein was observed in the treated sample. Arylphorin, ecdysone receptor, and apolipophorin-III were identified as the top-score immune proteins through MALDI-TOF/MS analysis. The docking result revealed the interaction between bacterial cell membrane protein (lipopolysaccharide) and the isolated proteins.

Summary: Synthetic pesticides pose significant problems in both terrestrial and aquatic habitats. Green pesticides derived from fungi provide efficient alternatives to chemical pesticides. Secondary metabolites from Metarhizium anisopliae showed low toxicity against major disease mosquitos and non-target species, while also exhibiting minimal harm to earthworms. The primary components of the fungal crude extract were identified, and the functional groups potentially responsible for mosquitocidal activity were revealed.
