Effects of a rollator on fall prevention in Community-Dwelling people with Parkinson's Disease: A prospective cohort study.

Introduction: This study aimed to investigate the effect of a rollator on the prevention of falls in patients with Parkinson's disease (PD) during outdoor walks.

Method: This study examined 30 community-dwelling patients with PD. Factors associated with falls were classified into clinical patient background, physical function, and psychophysiological function factors.

Biological effects of carbon ion beams with various LETs on budding yeast Saccharomyces cerevisiae.

It has been established that irradiation with higher linear energy transfer (LET) increases lethality and mutagenicity more than that with lower LET. However, the characteristics specific to carbon ion beam have not yet been elucidated. Yeast cells were irradiated with carbon ions with an LET of 13 or 50keV/μm, and cell survival and mutation frequency were analyzed.

Clustered DNA damage on subcellular level: effect of scavengers.

Clustered DNA damages are induced by ionizing radiation, particularly of high linear energy transfer (LET). Compared to isolated DNA damage sites, their biological effects can be more severe. We investigated a clustered DNA damage induced by high LET radiation (C 290 MeV u(-1) and Fe 500 MeV u(-1)) in pBR322 plasmid DNA.

Increased serum GP88 (Progranulin) concentrations in rheumatoid arthritis.

GP88 (Progranulin; PGRN) is a secreted glycosylated protein with important functions in several processes, including immune response and cancer growth. Recent reports have shown that PGRN is a therapeutic target for rheumatoid arthritis (RA) because of its capability to bind with tumor necrosis factor receptor (TNFR). However, the serum PGRN level in RA patients has not been investigated.

Effects of various phytochemicals on indoleamine 2,3-dioxygenase 1 activity: galanal is a novel, competitive inhibitor of the enzyme.

Indoleamine 2,3-dioxygenase (IDO) 1, that catalyzes the first and rate-limiting step in the degradation of L-tryptophan, has an important immunomodulatory function. The activity of IDO1 increases in various inflammatory diseases, including tumors, autoimmune diseases, and different kinds of inflammation. We evaluated the suppressive effect of plant extracts or phytochemicals on IDO1 induction and activity; sixteen kinds of plants extracts and fourteen kinds of phytochemicals were examined.
