Objective: To evaluate the role of developmental stimulation and nutritional supplementation in rehabilitation of malnourished children in the hospital and community settings.
Design: Prospective follow up study.
Settings: (i) Nutrition clinic of a teaching hospital; and (ii) Community Nutrition Project in coastal Kerala.
Subjects: (i) Hospital study: 100 children aged 6-24 months with moderate and severe Protein Energy Malnutrition (PEM) constituted the study group. The control group consisted of well nourished children matched for age and sex, 50 from high (Control I) and 50 from low socioeconomic (SE) status (Control II). The study group was randomized into two subgroups to administer the interventions namely composite stimulation package (STIM) or nutritional management (NUT). (ii) COMMUNITY STUDY: A cohort of 332 children aged 6-24 months with varying grades of PEM were studied. As per the area of residence, they were divided into three subgroups; 2 study groups to administer the two interventions namely STIM or NUT and a control group.
Methods: In both the hospital and community studies, environmental parameters, growth and development were assessed initially. After two years, the study groups were reassessed in comparison with the control groups. A final IQ assessment was done in each subgroup by a tester blinded to the grouping.
Results: (i) Hospital study: Control children from high SE status (Control I) had the highest overall scores compared to those from low SE status (Control II) as well as the study groups with PEM even after administering either STIM or NUT. Both the interventions produced a significant positive impact on growth and development, but STIM was found superior to NUT. (ii) Community study: There was a high prevalence of PEM in the community, which reduced significantly after the interventions. STIM was found superior in its positive impact on growth and development. In both studies, direct correlation was observed between environmental parameters and anthropometric scores and between anthropometric scores and IQ.
Conclusions: The benefit of developmental stimulation in nutritional rehabilitation and the need for providing better environment for deprived children are brought out in this study.

Objective: Acetylcholine modulates the activity of the direct and indirect pathways within the striatum through interaction with muscarinic M and M receptors. M receptors are uniquely positioned to regulate plasticity within the direct pathway and play a substantial role in reward and addiction-related behaviors. However, the role of M receptors on cholinergic neurons has been less explored.

Methyl 2-{[1-(5-fluoropentyl)-1H-indazole-3-carbonyl]amino}-3,3-dimethylbutanoate (5F-ADB), which is classified as an illicit drug in China and most European countries, is susceptible to abuse. The abuse of 5F-ADB must avoid entering the water environment. However, the aquatic toxic effects of 5F-ADB remain unclear.

Unlabelled: Diverse marine animals undergo a metamorphic larval-to-juvenile transition in response to surface-bound bacteria. Although this host-microbe interaction is critical to establishing and maintaining marine animal populations, the functional activity of bacterial products and how they activate the host's metamorphosis program has not yet been defined for any animal. The marine bacterium stimulates the metamorphosis of a tubeworm called by producing a molecular syringe called metamorphosis-associated contractile structures (MACs).

Several studies indicate various pharmacological and therapeutic effects of peroxisome proliferator-activated receptors (PPARs) in different disorders. The current review describes the influences of PPARs on respiratory, allergic, and immunologic diseases. Various databases, including PubMed, Science Direct, and Scopus, were searched regarding the effect of PPARs on respiratory and allergic disorders from 1990 to 2024.

Perfluorohexanoic acid (PFHxA) and perfluorobutanoic acid (PFBA) are widely used substitutes to perfluorooctanoic acid (PFOA). Whether these substitutes are less toxic than PFOA remains unclear owing to differences in the experimental methods, test organisms, and other experimental conditions in previous studies.
