Pathophysiology of Diabetes01:20

Pathophysiology of Diabetes

3.7K
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Hypertension II: Pathophysiology

1.1K
Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...

Pathophysiology of Vomiting01:22

Pathophysiology of Vomiting

3.2K
Vomiting is a complex physiological response to expel harmful or irritating substances from the body. It's a defensive mechanism triggered by stimuli like poisons, microbial toxins, cytotoxic drugs, and mechanical abdominal distension. The process is centrally coordinated by the vomiting (or emetic) center located in the medulla of the brainstem. This area, rich in muscarinic M1, histamine H1, neurokinin 1 (NK1), and serotonin 5-HT3 receptors, coordinates the act of vomiting through...

Gastritis-II: Pathophysiology01:17

Gastritis-II: Pathophysiology

1.4K
Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Heart Failure II: Pathophysiology01:29

Heart Failure II: Pathophysiology

1.0K
Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...

Area of Science:

  • Neurology
  • Neuroscience
  • Biomedical Engineering

Background:

  • Tremor is a rhythmic body movement impairing coordinated actions.
  • It can be a symptom (e.g., Parkinson's disease resting tremor) or a primary condition (e.g., essential, orthostatic tremor).
  • Cerebral, spinal, and muscular mechanisms are crucial in tremor development.

Purpose of the Study:

  • To review recent advances in understanding tremor pathophysiology.
  • To discuss new imaging and electrophysiological findings.
  • To explore evolving pathophysiological models of tremor.

Main Methods:

  • Review of new imaging studies.
  • Analysis of electrophysiological studies.
  • Discussion of established and emerging pathophysiological models.

Main Results:

  • Pathophysiology understanding has advanced significantly.
  • Models evolved from localized generators to network perspectives.
  • Tremor arises and spreads through brain networks.

Conclusions:

  • New insights into tremor pathophysiology are emerging.
  • Network-based models are increasingly important.
  • Translational approaches may lead to novel therapeutic strategies for tremor.
