Cushing Syndrome II: Pathophysiology01:19

Cushing Syndrome II: Pathophysiology

Cortisol production is normally governed by the hypothalamic–pituitary–adrenal (HPA) axis, which maintains hormonal balance through tightly regulated feedback mechanisms. Disruption of this regulatory system is central to the development of Cushing syndrome, whether the excess cortisol originates from external medications or internal pathology. Persistent cortisol elevation alters metabolism, immune function, and endocrine signaling, producing the characteristic clinical features of the...
Cross-bridge Cycle01:26

Cross-bridge Cycle

As muscle contracts, the overlap between the thin and thick filaments increases, decreasing the length of the sarcomere—the contractile unit of the muscle—using energy in the form of ATP. At the molecular level, this is a cyclic, multistep process that involves binding and hydrolysis of ATP, and movement of actin by myosin.
Chronic Obstructive Pulmonary Disease01:24

Chronic Obstructive Pulmonary Disease

COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
Huntington Disease l: Introduction01:21

Huntington Disease l: Introduction

Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show reduced penetrance,...
Chronic Pancreatitis I: Introduction01:24

Chronic Pancreatitis I: Introduction

The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
Chronic Pancreatitis I: Introduction01:25

Chronic Pancreatitis I: Introduction

Chronic pancreatitis is a long-standing, relapsing inflammation of the pancreas, characterized by irreversible damage to the gland. It results in progressive destruction of the pancreatic parenchyma, fibrosis, and eventual loss of both exocrine and endocrine function. The disease may evolve gradually after multiple episodes of acute pancreatitis or develop independently.EtiologyChronic pancreatitis can arise from a variety of causes:Alcohol use is the leading cause, accounting for 70–80% of...

Area of Science:

  • Veterinary neurology and wildlife pathology.
  • Prion disease epidemiology and host-pathogen interactions.

Background:

  • Chronic wasting disease (CWD) is a significant epidemic affecting free-ranging animals, primarily in North America.
  • As the most efficiently transmitted prion disease, CWD poses a potential risk for intercontinental spread.
  • Understanding CWD's host range and transmission dynamics is crucial for wildlife health management.

Purpose of the Study:

  • To provide a comprehensive review of the host range of Chronic Wasting Disease (CWD).
  • To explore potential transmissibility of CWD to humans and other species.
  • To summarize current knowledge on CWD pathogenesis, clinical signs, and detection methods.

Main Methods:

  • Literature review of experimental CWD infections in various animal models.
  • Analysis of reported CWD cases in wild and captive animal populations.
  • Compilation of data on CWD pathogenesis, clinical manifestations, and diagnostic techniques.

Main Results:

  • CWD affects a broad range of cervid species and has been experimentally transmitted to several other animal models.
  • The high efficiency of CWD transmission necessitates vigilance regarding its potential spread.
  • Established methods for CWD detection and understanding of its pathogenesis are detailed.

Conclusions:

  • Chronic wasting disease represents a major threat to wildlife populations due to its efficient transmission and broad host range.
  • Continued research into CWD's transmissibility, pathogenesis, and detection is essential for effective management and mitigation strategies.
  • The potential for CWD to spread globally underscores the need for international surveillance and cooperation.
