Chemotherapy-Induced Nausea and Vomiting: Cannabinoids01:21

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids

889
Tetrahydrocannabinol (THC) is a phytocannabinoid that primarily interacts with the CB1 receptor, a type of G protein-coupled receptor (GPCR) predominantly in and around the chemoreceptor trigger zone (CTZ) and emetic center. THC also blocks the serotonin receptor activity in the dorsal vagal complex (DVC) by inhibiting serotonin release. THC exerts its anti-emetic effects through these interactions, which are beneficial for patients undergoing chemotherapy.
Two synthetic agonists of THC,...

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids01:24

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids

1.1K
CNS stimulants, such as cocaine, amphetamines, and cannabinoids, have varying structures and mechanisms of action that lead to different therapeutic effects and side effects. Cocaine, with its molecular formula C17H21NO4, is a tropane alkaloid and a tertiary amino compound. It has two chemical forms: the hydrochloride salt and the "freebase." The former is in powder form, while the latter involves removing the hydrochloride salt to create a form that can be smoked. Cocaine exerts its...

Opioid Receptors: Overview01:22

Opioid Receptors: Overview

5.9K
Opioid receptors, including the mu (μ, MOR), delta (δ, DOR), and kappa (κ, KOR) types, belong to the rhodopsin family of G protein-coupled receptors. These receptors are located throughout the central and peripheral nervous systems and in non-neuronal tissues such as macrophages and astrocytes. Opioid receptor ligands can be categorized into agonists or antagonists. Highly selective agonists include [d-Ala2, MePhe4, Gly(ol)5]-enkephalin or DAMGO for MOR, [D-Pen2,...

Gonadal and Placental Hormones

3.7K
The gonads, namely the testes in males and the ovaries in females, are pivotal in producing gonadal hormones that orchestrate the intricate processes of sexual development and reproduction.
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair...

Analgesia and Pain Management01:25

Analgesia and Pain Management

2.6K
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

Area of Science:

  • Reproductive biology
  • Endocrinology
  • Neuroscience

Background:

  • The endocannabinoid system (eCS) comprises endogenous ligands, cannabinoid receptors (CB1, CB2), and associated enzymes.
  • The eCS is increasingly recognized for its significant role throughout mammalian reproduction.

Purpose of the Study:

  • To review the multifaceted role of the eCS in key reproductive stages, including implantation, pregnancy progression, and placentation.
  • To explore the molecular mechanisms underlying eCS involvement in pregnancy.
  • To discuss the challenges in therapeutically targeting the eCS for female infertility.

Main Methods:

  • Comprehensive literature review of animal and human studies.
  • Analysis of evidence on eCS function in implantation, early-to-late pregnancy, and placentation.
  • Examination of molecular pathways and regulatory mechanisms.

Main Results:

  • The eCS is integral to successful embryo development, blastocyst implantation, decidualization, and placentation.
  • Dysregulation of the eCS, through exogenous cannabis use or endogenous cannabinoid imbalance, is linked to adverse pregnancy outcomes.
  • Specific molecular mechanisms of eCS action during pregnancy require further elucidation.

Conclusions:

  • The endocannabinoid system is a critical regulator of successful pregnancy, with significant implications for reproductive health.
  • Understanding eCS function is vital for addressing pregnancy complications and female infertility.
  • Targeting the eCS presents therapeutic potential but also significant challenges in clinical application.
