The factors affecting adherence to a long-term interval walking training program in middle-aged and older people.

No long-term exercise training regimen with high adherence and effectiveness in middle-aged and older people is broadly available in the field. We assessed the adherence to, and effects of, our long-term training program comprising an interval walking training (IWT) and an information technology network system and the factors affecting adherence. Middle-aged and older men and women [n = 696, aged 65 ± 7(SD) yr] underwent IWT.

[A case report of early-onset Alzheimer's disease with multiple psychotic symptoms, finally diagnosed as APPV717I mutation by genetic testing].

It is difficult to confirm a diagnosis of early-onset Alzheimer's disease (EOAD) because patients sometimes have non-specific cortical features, such as psychiatric symptoms, executive functional impairment, and pyramidal symptoms, along with typical symptoms, such as recent memory impairment and disorientation. We encountered a patient with multiple psychotic symptoms, finally diagnosed with EOAD on genetic testing. A right-handed sixty-year-old man, whose mother was suspected of having dementia, developed memory impairment at the age of fifty, disorientation at the age of fifty-six, and both visual hallucination and dressing apraxia at the age of fifty-nine.

Genomics of vasculitis: lessons from mouse models.

A genome analysis of mouse models may shed some light on the complex clinicopathological manifestations of systemic vasculitis. In the study of susceptibility loci to vasculitis in MRL mouse models, we found that systemic vasculitis developed through the cumulative effect of multiple gene loci, each of which by itself did not have a significant effect in inducing the related phenotype, thus indicating a polygenic system. The mice developed vasculitis in an additive manner with a hierarchical effect.

Subcutaneous injection containing IL-3 and GM-CSF ameliorates stab wound-induced brain injury in rats.

Macrophage-like cells densely accumulate in stab wound-induced brain lesions in rats. Many of these cells express the macrophage marker Iba1 and the oligodendrocyte progenitor cell marker NG2 chondroitin sulfate proteoglycan (NG2), and have been termed BINCs (brain Iba1(+)/NG2(+) cells). Results from our previous study showed that BINCs elicit neuroprotective action, and agents inducing BINC activation or proliferation are expected to ameliorate traumatic brain injuries (TBIs).

Quadriceps sarcopenia and visceral obesity are risk factors for postural instability in the middle-aged to elderly population.

Aim: Aging shifts body composition to comprising more fat and less muscle. Sarcopenia, particularly in the knee extensors, and obesity, particularly visceral obesity, either alone or in combination, may exacerbate age-related physical disability. We investigated the association between age-related quadriceps (Qc) sarcopenia and visceral obesity, as measured by cross-sectional area (CSA), on postural instability.
