BACKGROUND Lumbar disc disease has a disabling impact on global people with heavy burden on society, mainly consisting of lumbar disc degeneration (LDD) and lumbar disc herniation (LDH). The recently released lumbar disc nomenclature version 2.0 deepens our understandings on the diseases. Consequently, there is an urgent need to clarify the occurrence and distribution features of LDD and LDH in...

BACKGROUND Hypertension and diabetes are significantly associated with insulin resistance (IR), which could affect the vasodilatory capacity and microcirculation. The aim of the study was to verify whether IR is associated with a reduced microvascular blood flow in normoglycemic mild hypertensives. METHODS Eighty-four untreated grade-1 hypertensives were equally divided, according to the IR h...

Glucose is a main metabolic substrate in the central nervous system (CNS). Recently, lactate has attracted renewed attention because it plays an important role in the CNS as a metabolic substrate between neurons and astrocytes. Lactate and lactate dehydrogenase (LDH), a key enzyme for lactate and pyruvate interconversion, have been investigated. The glycogen body (GB) is a gelatinous tissue in ...

BACKGROUND The prognosis of patients with metastatic osteosarcoma remains poor. However, the chance of survival can be improved by surgical resection of all metastases. In this study we investigate the value of serum alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) in predicting the presence of metastatic disease at time of diagnosis. METHODS Sixty-one patients with histologically c...

In acute aortic syndromes (AAS), organ malperfusion represents a key event impacting both on diagnosis and outcome. Increased levels of plasma lactate dehydrogenase (LDH), a biomarker of malperfusion, have been reported in AAS, but the performance of LDH for the diagnosis of AAS and the relation of LDH with outcome in AAS have not been evaluated so far.This was a bi-centric prospective diagnost...

PURPOSE Circulating molecules play important roles in lung cancer diagnosis. In addition, plasma lactate dehydrogenase (LDH) and creatine kinase (CK) have been shown to be closely related to tumor progression in breast cancer, prostate cancer, and colonel cancer. However, the relationships between LDH and CK levels with metastasis occurrence and the survival status of lung cancer patients remai...

BACKGROUND Bronchiolitis is the leading cause of hospitalization in infants. Biomarkers of disease severity might help in clinical management. OBJECTIVE To determine the clinical predictiveness of NW-LDH, NW-caspase 3/7, and NW-LDH/NW-caspase 3/7 ratio in bronchiolitis. METHODS Previously healthy children less than 24 months of age with bronchiolitis were recruited from the Texas Children's...

BACKGROUND To investigate the impact of pre-treatment lactate dehydrogenase (LDH) levels on the outcome of patients with metastatic colorectal cancer treated with first-line chemotherapy with or without the anti-VEGF monoclonal antibody, bevacizumab, in a phase III prospective multicentre randomized ITACa (Italian Trial in Advanced Colorectal Cancer) trial. METHODS Three hundred and seventy p...

To evaluate the potential role of mitochondrial lactate dehydrogenase (LDH) in tissue lactate clearance and oxidation in vivo, isolated rat liver, cardiac, and skeletal muscle mitochondria were incubated with lactate, pyruvate, glutamate, and succinate. As well, alpha-cyano-4-hydroxycinnamate (CINN), a known monocarboxylate transport inhibitor, and oxamate, a known LDH inhibitor were used. Mito...

Higher rate of glycolysis has been long observed in cancer cells, as a vital enzyme in glycolysis, lactate dehydrogenase A (LDH-A) has been shown with great potential as an anti-cancer target. Accumulating evidence indicates that inhibition of LDH-A induces apoptosis mediated by oxidative stress in cancer cells. To date, it's still unclear that whether autophagy can be induced by LDH-A inhibiti...
