Usefulness of Fibrinogen/Fibrin Degradation Products Value in Differential Diagnosis Between Acute Ischemic Stroke and Acute Aortic Dissection.

A post-marketing surveillance study reported fatalities following tissue plasminogen activator administration in acute aortic dissection (AAD) with the symptoms of acute ischemic stroke (AIS) patients. Therefore, it is important to discriminate AAD from AIS. The present study aimed to investigate whether fibrinogen/fibrin degradation products (FDP) value can be useful in differential diagnosis between AAD and AIS.

A Case of Infectious Enterocolitis with Hyperammonemia.

Case reports of hyperammonemia due to urease-producing bacteria are found occasionally, but most of them are associated with urinary tract infections. We experienced a case of infectious enterocolitis with hyperammonemia in which the causative bacteria was speculated to be urease-producing bacteria. A Japanese woman in her 70s had been diagnosed with microscopic polyangiitis in a nearby hospital and was transferred to our hospital.

[A Case of Life-Threatening Angioedema Occurred During Prolonged Angiotensin-Converting Enzyme Inhibitor Treatment].

Although angiotensin-converting enzyme (ACE) inhibitors are widely used as the first choice drug for treating hypertension, we have only a superficial understanding of their relationship to angioedema. We report a case of life-threatening angioedema. The case was a 60-year-old man who had been taking an ACE inhibitor for hypertension for 11 years.

[Examination of relationship between lactate clearance and neurologic outcome in cardiac arrest induced by ventricular fibrillation].

A significant relationship between lactate clearance and mortality rates in cardiac arrest cases has been reported. However, the relationship between lactate clearance and neurologic outcomes in cardiac arrest cases is not clear. We examined lactate clearance in cardiac arrest cases induced by ventricular fibrillation.

[A case of accidental hypothermia caused by cervical spinal cord injury].

Accidental hypothermia is the state in which body temperature falls due for exposure to a chilly environment. In accidental hypothermia, the mortality rate is higher the lower the body temperature. We report a case of a consciousness disorder and severe hypothermia, with a body temperature below 28 degrees C, in which it later became clear that a cervical spinal cord injury had been caused by a small external force.

Continuous mild heat stress induces differentiation of mammalian myoblasts, shifting fiber type from fast to slow.

Local hyperthermia has been widely used as physical therapy for a number of diseases such as inflammatory osteoarticular disorders, tendinitis, and muscle injury. Local hyperthermia is clinically applied to improve blood and lymphatic flow to decrease swelling of tissues (e.g.

Age-related increase of insoluble, phosphorylated small heat shock proteins in human skeletal muscle.

Among mammalian heat shock proteins (Hsps), small Hsps (sHsps) are constitutively expressed in skeletal muscles. We investigated age-related changes of phosphorylation and cellular distribution of representative sHsps (Hsp27 and alphaB-crystallin) in human vastus lateralis muscle under resting conditions. We also examined upstream kinases which may be responsible for phosphorylation of sHsps, namely p38 mitogen-activated protein kinase (MAPK), MAPK-activated protein kinase-2, and extracellular signal-regulated kinase-1/2.

Molecular aspects of adrenal regulation for circadian glucocorticoid synthesis by chronic voluntary exercise.

Chronic voluntary running of mice is known to increase the circadian peak of plasma corticosterone without change in the level of adrenocorticotropic hormone (ACTH). In order to investigate how chronic exercise modulates the circadian HPA axis, we used two weeks of voluntary wheel running of mice and confirmed the significant increase of the circadian peak of plasma corticosterone without alteration in ACTH level. To elucidate the mechanisms of exercise modulation on corticosterone synthesis, we first examined the levels of transcripts involved in corticosterone synthesis of the adrenal gland.

Antiamyloidogenic and neuroprotective functions of cathepsin B: implications for Alzheimer's disease.

Alzheimer's disease (AD) may result from the accumulation of amyloid-beta (Abeta) peptides in the brain. The cysteine protease cathepsin B (CatB) is associated with amyloid plaques in AD brains and has been suspected to increase Abeta production. Here, we demonstrate that CatB actually reduces levels of Abeta peptides, especially the aggregation-prone species Abeta1-42, through proteolytic cleavage.

Suppression of cofilin phosphorylation in insulin-stimulated ruffling membrane formation in KB cells.

Various cellular events such as cell motility and division are directed by the actin cytoskeleton under the control of its regulatory system. Cofilin is a low molecular weight actin-modulating protein that severs and depolymerizes F-actin and is shown to enhance actin filament dynamics. The activity of cofilin is negatively regulated by phosphorylation at Ser-3.
