Background: Nicotinamide adenine dinucleotide (NADH) dehydrogenase subunit-2 237 leucine/methionine (ND2-237 Leu/Met) polymorphism has been shown to modify the association of coffee consumption with the risk of hypertension, dyslipidemia, and abnormal glucose tolerance, and low serum chloride levels have been shown to be associated with all-cause and cardiovascular disease mortality. Therefore, the purpose of the present study was to investigate whether ND2-237 Leu/Met polymorphism influences the association of coffee consumption with serum chloride levels in male Japanese health checkup examinees.

Methods: From among individuals visiting the hospital for a regular medical checkup, 402 men (mean age ± standard deviation, 53.

Background: Several genetic polymorphisms have been reported to modify the effects of smoking on serum lipid levels. The objective of this study was to investigate whether longevity-associated mitochondrial DNA 5178 (Mt5178) C/A polymorphism modifies the effects of habitual smoking on the risk of dyslipidemia in middle-aged Japanese subjects.

Methods: A total of 394 male subjects (age, 53.

Pulmonary function is a crucial factor associated with longevity. Mitochondrial DNA 5178 cytosine/adenine (Mt5178 C/A) polymorphism is reported to be associated with longevity in the Japanese population. We have previously reported that Mt5178 C/A polymorphism is widely associated with physiological and biochemical status.

NADH dehydrogenase subunit-2 237 leucine/methionine (ND2-237 Leu/Met) polymorphism is associated with longevity in the Japanese population, and the ND2-237Met genotype may exert antiatherogenic effects. To investigate whether ND2-237 Leu/Met polymorphism is associated with risk of hypertension, we conducted a cross-sectional study of 398 Japanese male subjects. The frequency of hypertension was significantly higher in ND2-237Leu genotypic men than in ND2-237Met genotypic men.

NADH dehydrogenase subunit-2 237 leucine/methionine (ND2-237 Leu/Met) polymorphism is reportedly associated with longevity in the Japanese population. The ND2-237Met genotype may confer resistance to cardiovascular and cerebrovascular atherogenic diseases. Hyperuricemia is one of the risk factors for cardiovascular disease.

Mitochondrial DNA 5178 cytosine/adenine (Mt5178 C/A) polymorphism is reportedly associated with longevity in the Japanese population, and the Mt5178A genotype may resist the onset of type 2 diabetes. To investigate whether Mt5178 C/A polymorphism is associated with glucose tolerance, we conducted a cross-sectional study using the 75-g oral glucose tolerance test (OGTT) in which non-diabetic Japanese male subjects were classified into three subgroups by body mass index (BMI): BMI<22 (n=91); 22< or =BMI<25 (n=138); and BMI> or =25 (n=67). The frequency of Mt5178A was significantly lower among 'BMI<22' subjects exhibiting impaired fasting glucose and impaired glucose tolerance than among those with normal glucose tolerance.

Mitochondrial DNA 5178 cytosine/adenine polymorphism, which is also called NADH dehydrogenase subunit-2 237 leucine/methionine (ND2-237 Leu/Met) polymorphism is associated with Japanese longevity. This polymorphism is widely associated with blood pressure, serum lipid levels, hematological parameters, intraocular pressure, and serum protein fraction levels. However, there have been no reports on the association between ND2-237 Leu/Met polymorphism and serum electrolyte levels.

There are two foci of alveolar echinococcosis (AE) caused by Echinococcus multilocularis in Japan. The first focus is on Rebun Island where AE patients were found from 1937, and the second is in eastern Hokkaido where patients have been found since the 1960s. The origin of the second focus is unknown.

Mitochondrial DNA 5178 C/A (mt5178 C/A), namely NADH dehydrogenase subunit 2 237 Leu/Met, polymorphism is as reported in literature associated with longevity and susceptibility to ischemic heart disease or cerebrovascular disorders in the Japanese population. Previous reports suggested that mt5178A genotype exerts antiatherogenic effects. The aim of this study was to investigate whether mt5178 C/A polymorphism is associated with hematological parameters, such as thrombogenic risk factors for myocardial infarction and stroke, in 321 healthy Japanese men.

Strongyloidiasis is an intestinal parasite infection caused by Strongyloides stercoralis. Spontaneous cure cannot be expected due to the unique life cycle of the parasite, termed autoinfection. The disease occurs worldwide, but especially in tropical and subtropical regions.

It is difficult to completely eradicate strongyloidiasis, a human intestinal nematode infection with Strongyloides stercoralis with drugs, especially in males. To find host factors involved in the response to treatment, patients infected with S. stercoralis were examined for S.

Background: Mitochondrial DNA 5178 adenine/cytosine (mt5178 A/C) polymorphism has been reported to be associated with longevity in Japanese individuals, with experimental findings concluding that mt5178 A is an anti-atherogenic genotype. The aim of this study was to determine whether mt5178 A/C polymorphism influences intraocular pressure (IOP), and its relationship with the development of arteriosclerosis.

Methods: Four hundred and forty-nine male volunteers who had visited a general hospital for medical check-up between August 1999 and August 2000 were enrolled.

We report a 47-year-old Japanese man who was a human T-cell leukemia virus type 1 (HTLV-1) carrier with strongyloidiasis, and who was born in an area endemic for both Strongyloides stercoralis ( S. stercoralis) and HTLV-1. He presented with edema of both legs.

Mitochondrial DNA 5178 adenine/cytosine (mt5178 A/C) polymorphism is one of the longevity-associated mitochondrial DNA polymorphisms. The frequency of the mt5178A genotype is significantly higher in Japanese centenarians than in the general population. We previously reported that serum high-density lipoprotein cholesterol levels were significantly higher in men with mt5178A than in those with mt5178C.

Mitochondrial DNA 5178 adenine/cytosine (mt5178 A/C) polymorphism is reportedly associated with longevity and susceptibility to age-related diseases in Japanese individuals. We previously reported an association between mt5178 A/C polymorphism and serum protein fraction levels in healthy Japanese women. An association between habitual smoking and serum protein fraction levels has also been reported previously.

Mitochondrial DNA 5178 adenine/cytosine (mt5178 A/C) polymorphism was reported to be associated with longevity and susceptibility to adult-onset diseases in Japanese. To examine whether mt5178 A/C genotypes are associated with serum protein fraction profiles, we genotyped 461 healthy Japanese individuals, and studied the relationship of mt5178 A/C genotypes to both proportion and levels of serum protein fraction. The mt5178 A/C was genotyped using polymerase chain reaction-restriction fragment length polymorphism method.
