pyruvate kinase/asthenia

Red cell pyruvate kinase deficiency is the most common glycolytic defect associated with congenital non-spherocytic hemolytic anemia. The disease, transmitted as an autosomal recessive trait, is caused by mutations in the PKLR gene and is characterized by molecular and clinical heterogeneity; anemia

BACKGROUND Erythrocyte pyruvate kinase deficiency (PK deficiency) is an inherited hemolytic anemia that has been documented in the Abyssinian and Somali breeds as well as random bred domestic shorthair cats. The disease results from mutations in PKLR, the gene encoding the regulatory glycolytic

Myotonic dystrophy type 1 (DM1) is caused by expansion of CTG repeats in the 3' UTR of the DMPK gene. Expression of CUG expansion (CUG(exp)) RNA produces a toxic gain of function by disrupting the functions of RNA splicing factors, such as MBNL1 and CELF1, leading to splicing changes associated with

OBJECTIVE Pyruvate kinase deficiency (PKD) is a rare disease and understanding of its epidemiology and associated burden remains limited. With no current curative therapy, clinical manifestations can be life threatening, clinically managed by maintaining adequate hemoglobin levels through

An 11-year-old female crossbred dog showed signs of polyuria, polydipsia, vomiting, posterior weakness and ataxia. Clinical and laboratory findings suggested the diagnosis of polycythaemia vera. The haematological values shown over a six-month period are presented. In four samples some aspects of

Glycogen disease type III (GSDIII), a rare incurable autosomal recessive disorder due to glycogen debranching enzyme deficiency, presents with liver, heart and skeletal muscle impairment, hepatomegaly and ketotic hypoglycemia. Muscle weakness usually worsens to fixed myopathy and cardiac involvement

Background: Dietary fish oil (DFO) has been identified as a micronutrient supplement with the potential to improve musculoskeletal health in old age. Few data are available for effects of DFO on muscle contractility, despite the

Extended longevity is often accompanied by frailty and increased susceptibility to a variety of crippling disorders. One of the most striking features of human aging is sarcopenia, which is defined as the age-related decline in skeletal muscle mass and strength. Although various metabolic and
