Muscle Recovery and Fatigue01:24

Muscle Recovery and Fatigue

1.9K
Muscle fatigue refers to the decline in a muscle's ability to maintain the force of contraction after prolonged activity. It primarily stems from changes within muscle fibers. Even before experiencing muscle fatigue, one may feel tired and have the urge to stop the activity. This response, known as central fatigue, occurs due to changes in the central nervous system, namely the brain and spinal cord. While there is no single mechanism that induces fatigue, it may serve as a protective...

Overview of Protein Metabolism01:21

Overview of Protein Metabolism

704
Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...

Lysosomal Hydrolases01:22

Lysosomal Hydrolases

3.7K
Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...

Disorders of the Skeletal Muscle01:28

Disorders of the Skeletal Muscle

860
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Smooth Endoplasmic Reticulum01:21

Smooth Endoplasmic Reticulum

5.6K
Smooth endoplasmic reticulum or smooth ER is a sub-organelle with specialized functions in animal cells and plant cells. It is often associated with the tubule morphology of the endoplasmic reticulum.
The ER provides optimal conditions for synthesizing steroid hormones and lipids, such as phospholipids and triglycerides. Traditionally, lipid metabolism was considered to be a smooth ER function. However, there is no direct evidence to prove that rough ER is completely excluded from lipid...

Amyloid Fibrils03:03

Amyloid Fibrils

9.2K
Amyloid fibrils are aggregates of misfolded proteins.  Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils. 
Amyloid deposits were observed as early as 1639 in the liver and the spleen.   In 1854, Rudolph Virchow performed iodine staining,...

Area of Science:

  • Equine medicine
  • Veterinary internal medicine
  • Equine exercise physiology

Background:

  • Exertional rhabdomyolysis (ER) is a common equine condition causing muscle damage.
  • Clinical signs include stiffness, pain, and reluctance to move.
  • Diagnosis relies on elevated serum creatine kinase (CK) activity concurrent with clinical signs.

Purpose of the Study:

  • To provide a comprehensive overview of exertional rhabdomyolysis (ER) in horses.
  • To focus on the treatment of acute ER and the causes and management of sporadic ER.
  • To discuss differential diagnoses for chronic ER, including recurrent ER and malignant hyperthermia.

Main Methods:

  • Literature review and synthesis of current knowledge on equine exertional rhabdomyolysis.
  • Discussion of diagnostic criteria and laboratory findings (e.g., serum CK).
  • Exploration of different ER classifications: sporadic (extrinsic causes) and chronic (intrinsic abnormalities).

Main Results:

  • Acute ER requires prompt diagnosis and management to prevent further muscle damage.
  • Sporadic ER is often linked to extrinsic factors and requires identification and avoidance of triggers.
  • Chronic ER encompasses intrinsic muscle function abnormalities, necessitating long-term management strategies.

Conclusions:

  • Effective management of equine exertional rhabdomyolysis involves accurate diagnosis and tailored treatment plans.
  • Understanding the distinct categories of ER (sporadic vs. chronic) is crucial for appropriate therapeutic approaches.
  • Further research into the pathophysiology and genetic predispositions of chronic ER forms is warranted.
