Retroperistalsis is the reverse of the involuntary smooth muscle contractions of peristalsis.It usually occurs as a precursor to vomiting.Local irritation of the stomach, such as bacteria or food poisoning, activates the emetic center of the brain which in turn signals an imminent vomiting reflex.
Common symptoms of food poisoning include stomach aches and pain, nausea, fever, vomiting, diarrhea and headache. "Those most at risk for severe foodborne illness include children under 5 ...
Some food poisoning cases can last 14 days, where you can just have continuous diarrhea,” Majlesi added. “Generally speaking, the more severe, the shorter the duration.” Is there a way to ...
Anabolism (/ ə ˈ n æ b ə l ɪ z ə m /) is the set of metabolic pathways that construct macromolecules like DNA or RNA from smaller units. [1] [2] These reactions require energy, known also as an endergonic process. [3] Anabolism is the building-up aspect of metabolism, whereas catabolism is the breaking-down aspect. Anabolism is usually ...
Degradation of nucleic acids is a catabolic reaction and the resulting parts of the nucleotides or nucleobases can be salvaged to recreate new nucleotides. Both synthesis and degradation reactions require multiple enzymes to facilitate the event. Defects or deficiencies in these enzymes can lead to a variety of diseases. [1]
Ornithine transcarbamylase (OTC) (also called ornithine carbamoyltransferase) is an enzyme (EC 2.1.3.3) that catalyzes the reaction between carbamoyl phosphate (CP) and ornithine (Orn) to form citrulline (Cit) and phosphate (P i). There are two classes of OTC: anabolic and catabolic. This article focuses on anabolic OTC.
The vomiting center of the brain refers to the groups of loosely organized neurons in the medulla that include the CTZ within the area postrema and the nucleus tractus solitarii. [2] One of the ways the chemoreceptor trigger zone implements its effects on the vomiting center is by activation of the opioid mu receptors and delta receptors. [6]
Prolonged and excessive vomiting depletes the body of water (dehydration), and may alter the electrolyte status. Gastric vomiting leads to the loss of acid (protons) and chloride directly. Combined with the resulting alkaline tide, this leads to hypochloremic metabolic alkalosis (low chloride levels together with high HCO − 3 and CO
