Physiologic and psychological effects of substance use are common occurrences. They may be the proximate purpose of the exposure or related to an unintended complication. Acute short-term exposure effects may not be the same as long-term effects. These effects are mediated by different receptors they act on and the homeostatic changes that occur due to repeat exposure. We review in this article the physiologic and psychological effects from exposure to commonly encountered drugs, ethanol, sedative hypnotics, cocaine, amphetamines, marijuana, opioids, nicotine, hydrocarbons (halogenated and non-halogenated), and nitrous oxide.

Background: The effect of high consumption of psychoactive substances of codeine (CDE), tramadol (TMD), and Cannabis sativa (CNB) as concoction has been associated with altered brain cognitive and neurochemical functions. However, the understanding of the complex mechanism behind the intake of Cannabis sativa co-administration with tramadol and codeine on both cardiac and brain function, neurotransmitters, purinergic, and antioxidant enzymes activities in the brain and heart of rats remains unreported.
Method: The measure of cognition using morris water maze (MWM) and Y-maze tests, hemodynamic parameters namely systolic blood pressure (SBP) and heart rate (HR), acetylcholinesterase (AChE), butyl-cholinesterase (BCHE), adenosine deaminase (ADA), arginase, catalase (CAT), superoxide dismutase (SOD) enzymes' activities, reduced glutathione (GSH) and malondialdehyde (MDA), nitric oxide (NO) levels, in the brain and heart of CNB, TMD, and CDE exposed rats was done.

Background: Alzheimer's disease is a brain disorder that causes neurodegeneration and is linked with insulin resistance at molecular, clinical, and demographic levels. Defective insulin signaling promotes Aβ aggregation and accelerates Aβ formation in the brain leading to Type III diabetes.
Objective: The objective of this research project is to demonstrate a linkage if any between the risk of developing Alzheimer's disease and insulin resistance.

Background: Despite some advances in treatment, a cure for Alzheimer's disease (AD) remains elusive. Disease hallmarks include heightened neuroinflammation and oxidative stress, associated with progressive decline in mobility and cognitive functions. Natural compounds provide a valuable reservoir of novel bioactive substances with therapeutic potential, fewer side effects, and increased affordability.

Background: Reducing chronic inflammation has been linked to anti-inflammatory foods and may be implicated in treating Alzheimer's disease (AD). Plants produce antioxidants, such as phytochemicals, that appear to reduce the incidence of chronic inflammatory diseases. Phytochemicals may include active substances like polyphenols.

Aim: Lebrikizumab is an interleukin (IL)-13 inhibitor that specifically blocks IL-13 signaling. Here, we report the effects of lebrikizumab on asthma serum biomarkers in 2 phase 3 clinical studies.
Methods: LAVOLTA I and LAVOLTA II are replicate, double-blind, placebo-controlled trials with 52-week placebo-controlled treatment periods that evaluated lebrikizumab 37.
