post-traumatic stress disorder/phosphatase

Patients suffering from severe head injury and fractures of long bones or large joints often show enhanced osteogenesis, with hypertrophic callus formation and/or heterotopic ossifications. The advantage of this phenomenon is early consolidation of the fractures. An extreme disadvantage is extensive

BACKGROUND Research in rodents demonstrated that psychological stress increases circulating levels of alanine transaminase, aspartate transaminase, and alkaline phosphatase reflecting liver injury. Moreover, chronic posttraumatic stress disorder and transaminases predicted coronary heart

OBJECTIVE To observe the changes of apoptosis and protein kinase B/the mammalian target of Rapamycin (Akt/mTOR) signal pathway in hippocampal neurons of rat with post-straumatic stress disorder (PTSD), and to investigate the mechanism of PTSD. METHODS Sixty male adult SD rats were divided into

Epilepsy is a significant but potentially preventable complication of traumatic brain injury (TBI). Previous research in animal models of acquired epilepsy has implicated the calcium-sensitive phosphatase, calcineurin. In addition, our lab recently found that calcineurin activity in the rat

Post-traumatic stress disorder (PTSD) is a mental disease associated with the exposure of traumatic stress, and results in the structural and functional changes of hippocampus. Calcineurin (CaN), a calcium/calmodulin-regulated protein phosphatase ubiquitously expressed in brain, has a very important

Post-traumatic acalculous cholecystitis is a potentially lethal complication that may develop in patients during hospitalization for trauma. Three case reports illustrate that obscuration of many early diagnostic symptoms and signs may make this complication particularly treacherous in the

Striatal-enriched protein tyrosine phosphatase (STEP) is a CNS-enriched protein implicated in multiple neurologic and neuropsychiatric disorders. STEP regulates key signaling proteins required for synaptic strengthening as well as NMDA and AMPA receptor trafficking. Both high and low levels of STEP

As latexin has been linked with chondrocyte hypertrophic differentiation it is possible that this protein may also be involved in the mineralization of cartilage in OA. Therefore, we correlated latexin expression with the mineralization marker, alkaline phosphatase and determined the mineral

BACKGROUND Osteoarthritis (OA) is a degenerative joint disease with poorly understood etiology and pathobiology. Mitogen activated protein kinases (MAPKs) including ERK and p38 play important roles in the mediation of downstream pathways involved in cartilage degenerative processes. Dual specificity

BACKGROUND Formation of long-term memories is critically dependent on extracellular-regulated kinase (ERK) signaling. Activation of the ERK pathway by the sequential recruitment of mitogen-activated protein kinases is well understood. In contrast, the proteins that inactivate this pathway are not as

Complex brain diseases and neurological disorders in human generally result from the disturbance of multiple genes and signaling pathways. These disturbances may derive from mutations, deletions, translocations or rearrangements of specific gene(s). However, over the past years, it has become clear

Previous studies showed that SDF-1α is a catabolic factor that can infiltrate cartilage, decrease proteoglycan content, and increase MMP-13 activity. Inhibiting the SDF-1α/CXCR4 signalling pathway can attenuate the pathogenesis of osteoarthritis (OA). Recent studies have also shown that SDF-1α

There are no treatments in clinical practice known to mitigate the neurobiological processes that convert a healthy brain into an epileptic one, a phenomenon known as epileptogenesis. Downregulation of protein phosphatase 2A, a protein that causes the hyperphosphorylation of tau, is implicated in

Hemobilia should be considered in all cases of blunt or penetrating trauma to the liver, no matter how trivial it may appear, whenever right upper quadrant pain and a persistently elevated alkaline phosphatase level give evidence of an otherwise unexplained biliary obstructin or hepatic mass lesion.
