Spinocerebellar ataxia type 1 (SCA1) is a neurodegenerative disorder caused by expansion of a CAG trinucleotide repeat. We analyzed CAG repeat expansion in one Japanese SCA1 family with mild clinical manifestations. Clinically, this SCA1 family showed less frequent nystagmus...

We report here a novel point mutation in exon 5 of the Cu/Zn superoxide dismutase (SOD) gene resulting in an amino acid substitution of valine(148) by isoleucine (V148I) in a Japanese family with amyotrophic lateral sclerosis (FALS). In this...

Concise set of files for smooth return to work in employees with mental disorders.

Springerplus. 2013 Nov 23;2:630. doi: 10.1186/2193-1801-2-630. eCollection 2013.

Sick leave due to mental disorders is a societal problem. It carries a high cost in terms of loss of labor productivity and absenteeism. Partial remission increases the risk of relapse after a return to work. There is sometimes...

Colorectal flat-type tumors include laterally spreading tumors (LSTs) and flat depressed-type tumors. The former of which shows a predominant lateral spreading growth rather than an invasive growth. The present study examined the morphological characteristics of LSTs, in comparison with...

Metal ion concentrations in the joint fluid immediately after total knee arthroplasty.

Modern rheumatology

Niki Y, Matsumoto H, Otani T, Suda Y, Toyama Y.
PMID: 24383725
Mod Rheumatol. 2001 Sep;11(3):192-6. doi: 10.3109/s101650170003.

Abstract Extensive research has demonstrated increased levels of blood metal ions caused by corrosion or wear of the metal after prosthetic implantations. However, metal ion levels in the joint fluid immediately after prosthetic implantation have not been investigated. We...

Promoting effects of antiandrogenic agents on rat ventral prostate carcinogenesis induced by 3,2'-dimethyl-4-aminobiphenyl (DMAB).

Prostate cancer and prostatic diseases
