An inclusive outlook on the fate and persistence of pesticides in the environment and integrated eco-technologies for their degradation.

Intensive and inefficient exploitation of pesticides through modernized agricultural practices has caused severe pesticide contamination problems to the environment and become a crucial problem over a few decades. Due to their highly toxic and persistent properties, they affect and get accumulated in non-target organisms, including microbes, algae, invertebrates, plants as well as humans, and cause severe issues. Considering pesticide problems as a significant issue, researchers have investigated several approaches to rectify the pesticide contamination problems.

Epigenetic (re)programming of gene expression changes of CB1R and FAAH in the medial prefrontal cortex in response to early life and adolescence stress exposure.

Environmental factors, including stress, that are experienced during early life (ELS) or adolescence are potential risk factors for the development of behavioral and mental disorders later in life. The endocannabinoid system plays a major role in the regulation of stress responses and emotional behavior, thereby acting as a mediator of stress vulnerability and resilience. Among the critical factors, which determine the magnitude and direction of long-term consequences of stress exposure is age, i.

Paternal Deprivation and Female Biparental Family Rearing Induce Dendritic and Synaptic Changes in Octodon degus: II. Nucleus Accumbens.

While the majority of studies on the importance of parental caregiving on offspring behavioral and brain development focus on the role of the mother, the paternal contribution is still an understudied topic. We investigated if growing up without paternal care affects dendritic and synaptic development in the nucleus accumbens of male and female offspring and if replacement of the father by a female caregiver "compensates" the impact of paternal deprivation. We compared (a) biparental rearing by father and mother, (b) monoparental care by a single mother, and (c) biparental rearing by two female caregivers.

Biological effects of ionizing radiation on aquatic biota - A critical review.

Ionizing radiation from radionuclides impacts marine aquatic biota and the scope of investigation must be wider than just invertebrates. We intend to detail and illustrate numerous biological effects that occur in both aquatic vertebrates and invertebrates, at various dose rates from all three kinds of ionizing radiation. The characteristics of radiation sources and dosages that would most effectively generate the intended effects in the irradiated organism were assessed once the biological differentiation between vertebrates and invertebrates was determined through multiple lines of evidence.

Development of ZnO/SnO/rGO hybrid nanocomposites for effective photocatalytic degradation of toxic dye pollutants from aquatic ecosystems.

The impact of ZnO/SnO/reduced graphene oxide nanocomposites (ZnO/SnO/rGO NCs) for improved photocatalytic degradation of organic dye pollution is examined in this study. The developed ternary nanocomposites had a variety of characteristics that were detected, such as crystallinity, recombination of photogenerated charge carriers, energy gap, and surface morphologies. When rGO was added to the mixture, the optical band gap energy of ZnO/SnO was lowered, which improved the photocatalytic activity.
