Depression is a well-known disabling mental illness characterized by sadness, loss of interest in activities, and decreased energy. The symptoms of depression are usually recurrent in vulnerable individuals, and persistence of symptoms significantly impairs individuals' quality of life. The exact pathophysiology of depression remains ambiguous, though many hypotheses have been proposed. Brain-derived neurotrophic factor (BDNF) has recently been reported to play a vital role in the pathophysiology of depression. BDNF is an important neurotrophic factor found in the human brain and is involved in neuronal growth and proliferation, synaptic neurotransmission, and neuroplasticity. The neurotrophic theory of depression proposes that depression results from reduced BDNF levels in the brain, which can be treated with antidepressants to alleviate depressive behavior and increase BDNF levels. The aim of this review is to provide broad insight into the role of BDNF in the pathogenesis of depression and in antidepressant therapy. The studies mentioned in this review article greatly support the role of BDNF in the pathogenesis of depression and treatment of this disorder with antidepressants. Since abnormalities in BDNF levels lead to the production of diverse insults that amplify the development or progression of depression, it is important to study and explore BDNF impairment in relation to depression, neuroplasticity, and neurogenesis, and increasing BDNF levels through antidepressant therapy, showing positive response in the management of depression.Cypermethrin activates microglia, which is found to be decisive in neurodegeneration in the experimental rats. While the involvement of microglial activation in toxicant-induced neurodegeneration is reported, the effect of low concentration of cypermethrin on the expression of inflammatory proteins from the rat primary microglia is not yet properly understood. The study intended to delineate the effect of low concentration of cypermethrin on the expression and release of proteins from the microglia. Rat primary microglial cells were treated with cypermethrin to check the expression of inflammatory proteins. Cypermethrin-treated microglia conditioned media and cells were collected to measure the expression and release of inflammatory proteins. Cypermethrin augmented the protein kinase C-δ (PKC-δ), inducible nitric oxide synthase (iNOS), phosphorylated mitogen-activated protein kinase (MAPK) p38 and p42/44, matrix metalloproteinase (MMP)-3, and MMP-9 levels in the cell lysate and tumour necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) levels in the microglia conditioned media. Pre-treatment with minocycline, a microglial activation inhibitor or rottlerin, a PKC-δ inhibitor, notably reduced the release of TNF-α in the conditioned media and expression of iNOS protein in the microglia. Minocycline reduced the expression of PKC-δ, phosphorylated p38 and p42/44 MAPKs, MMP-3, and MMP-9 proteins in the microglia. While cypermethrin-treated conditioned media induced the toxicity in the rat primary neurons, minocycline or rottlerin reduced the cypermethrin treated microglia conditioned media-induced toxicity. The outcomes of the present study suggest that cypermethrin activates microglia and releases TNF-α and IL-1β as well as up-regulates the expression of PKC-δ, iNOS, phosphorylated p38 and p42/44 MAPKs, MMP-3, and MMP-9 proteins, which could contribute to neurodegeneration.The remediation of wastewater (WW) is a promising solution for limited water sources. This study aimed to evaluate rice straw (RS) and zeolite (Z) as bioadsorbents for the removal of pollutants, including heavy metals (HMs) (cadmium [Cd], nickel [Ni], and lead [Pb]) and malathion (PC), from WW and to assess the suitability of reusing remediated WW in fish rearing units. TRULI A total of 11 treatment groups with 3 replicates each were designed with different combinations of RS and/or Z for the treatment of real WW contami
