Objective: Occupational health staff and managers play important roles in supporting workers with mental health concerns and mutual co-operation among them is a necessary element. However, when co-operating with other professionals, several problems arise that often make such co-operation a challenge. Effective mutual actions are needed to promote such co-operation, and relationships must be formed for this purpose.

The biologic activities of C1INH can be divided into the regulation of vascular permeability and anti-inflammatory functions. The objective was to clarify the serial change of C1INH in patients with sepsis.

We report a 4-year-old Japanese girl who presented with fever, facial erythema, joint pain, and oral ulceration. Complement deficiencies were suspected because of her persistent hypocomplementemia and normal levels of the complement proteins C3 and C4.

This is a 2010 year version and will be updated according to any pertinent medical advancements.

Invasive infections with Streptococcus pneumoniae that produce neuraminidase are a well-recognized cause of HUS without diarrhea. The Thomsen- Friedenreich antigen (T antigen) plays a role in the pathophysiology of pneumococcal HUS.

Here we present the case of a 27-year-old Japanese woman whose obstetric history involved three mid-trimester miscarriages (at 22 weeks', 18 weeks' and 21 weeks' gestation) and one early spontaneous miscarriage. Her fifth pregnancy was successfully managed by cervical cerclage at 13 weeks' gestation, followed by clindamycin administration (600 mg/day for 7 days) and progesterone injections (250 mg/week).

Patients with HAE are restricted in various medical treatments, which can induce an HAE attack. We herein report the first case of psoriatic arthritis (PSA) with type 1 HAE successfully treated with 25 mg of etanercept without HAE attack.

Tests revealed hypocomplementemia and elevated Antistreptolysin-O titers, and renal biopsy revealed endocapillary and mesangial proliferative glomerulonephritis with double contours of the glomerular basement membrane (GBM). Despite methylprednisolone pulse therapy and the administration of oral prednisolone, overt proteinuria and hypocomplementemia persisted.

First, we demonstrated that p21Waf1 expression was increased by TPA in other leukemia cell lines also, including THP-1, U937, and KG-1, which differentiate into monocytes/macrophages by TPA. Secondly, we demonstrated the signal transduction pathways of cyclin D1 and p21Waf1 expressions in TPA-treated HL60 cells.

Lack of caveolin-1 expression has been implicated in the pathogenesis of oncogenic cell transformation and tumorigenesis in many cancers. On the other hand, over-expression has also been associated with tumor progression and metastasis in prostate cancers.
View Article and Find Full Text PDFCaveolin, the essential structural component of caveolae, serves as a scaffolding protein onto which signaling molecules are assembled, and functions as a negative regulator for signal transduction. Caveolin-1 and -2 are expressed in most cell types, but are not expressed in normal blood cells and cell lines. We previously demonstrated that caveolin-1 is expressed in a panel of human leukemia cell lines that show an activated T cell phenotype.
