Toll-like receptors (TLRs) are the key regulators of innate and adaptive immunity and are highly expressed during sepsis. Thus, studying the expression of TLRs in an animal septic model might indicate their possible association with acute kidney injury in sepsis. Seventy-two male C57BL/6J mice were used for this study.

Sepsis was induced by cecal ligation and puncture (CLP) in the mice of the three septic (S) groups (euthanized at 24 hours, 48 hours and 72 hours).

We hypothesized that specific TLR members (TLR2, TLR3, TLR4, TLR8) may play a role in atherosclerosis progression and its accompanying inflammatory response. We determined the association of atherosclerotic lesions and TLR mRNA expression in different aortic sites.

Analysis of 25-year mortality data from the 16 cohorts of participants indicated that the cohort from Crete had the lowest age-standardised all-cause and coronary heart disease death rates.
Methods: At baseline, 686 Cretan men (98% of those invited) participated in health examinations.

Study Objective: Mortality over 25 years has been low in the Italian and very low in the Greek cohorts of the Seven Countries Study; factors responsible for this particularity were studied in detail.
Participants And Settings: 1712 Italian and 1215 Greek men, aged 40-59 years, cohorts of the Seven Countries Study, representing over 95% of the populations in designated rural areas.
Design: Entry (1960-61) data included age, systolic blood pressure (SBP), smoking habits, total serum cholesterol, body mass index (BMI), arm circumference, vital capacity (VC), and forced expiratory volume in 3/4 seconds (FEV); the same data were obtained 10 years later.
Background: This analysis explores whether 'typical' clinical manifestations of coronary heart disease (CHD) such as myocardial infarction and sudden death, relate to major cardiovascular risk factors in the same way as the 'atypical' manifestations, e.g. heart failure and chronic arrhythmias.

Sixteen cohorts of all men aged 40-59 in seven countries (one cohort in the USA, two in Finland, one in the Netherlands, three in Italy, two in Croatia (former Yugoslavia), three in Serbia (former Yugoslavia), two in Greece, two in Japan) were surveyed from 1958 to 1964. Risk factors and personal characteristics were measured and follow-up for vital status and cause of death was then carried out over 25 years.

The objective of this work was to study the risk of death during a 15-year follow-up of middle-aged men in relation to six chronic diseases. Fifteen cohorts of men aged 50-69, totalling 8122 subjects, were examined around 1970 in seven countries: Finland, The Netherlands, Italy, Croatia (former Yugoslavia), Serbia (former Yugoslavia), Greece and Japan.

Objective: To study the relationship between trends in coronary deaths and changes in blood cholesterol in the Seven Countries Study.
Material And Methods: Sixteen cohorts of men aged 40-59 years from seven countries (U.S.
Background And Purpose: This report explores the prediction of long-term stroke mortality in cohorts of the Seven Countries Study.
Methods: Sixteen cohorts of men aged 40 to 59 years at entry were examined at years 0, 5, and 10, with mortality follow-up through 25 years.
Results: Stroke death rates in 25 years were high in rural Serbia, Croatia, and Japan; intermediate in Italy, Greece, and urban Serbia; and low in Finland, the Netherlands, and the United States.
Background: It was hypothesized that among eight national groups of men aged 40-59 years enrolled in the Seven Countries Study, the multivariate coefficients of major risk factors predicting coronary heart disease mortality over 25 years would be relatively similar.
Materials And Methods: Sixteen cohorts were located in eight nations and pooled, comprising one cohort in the USA, two in Finland, one in the Netherlands, three in Italy, two in Croatia (former Yugoslavia), three in Serbia (Yugoslavia), two in Greece and two in Japan, for a total of over 12000 subjects at entry. Coronary heart disease (CHD) mortality was defined as fatal myocardial infarction or sudden coronary death, and proportional hazard models were solved, for each country, with age, serum cholesterol level, systolic blood pressure and cigarette consumption as covariates.
Objective: To compare the relationship between serum total cholesterol and long-term mortality from coronary heart disease (CHD) in different cultures.
Design: Total cholesterol was measured at baseline (1958 through 1964) and at 5- and 10-year follow-up in 12,467 men aged 40 through 59 years in 16 cohorts located in seven countries: five European countries, the United States, and Japan. To increase statistical power six cohorts were formed, based on similarities in culture and cholesterol changes during the first 10 years of follow-up.
This ecologic study aimed to investigate whether differences in population mortality from lung, stomach and colorectal cancer among the 16 cohorts of the Seven Countries Study could be explained by differences in the average intake of anti-oxidant (pro)vitamins. In the 1960s, detailed dietary information was collected in small sub-samples of the cohorts by the dietary record method. In 1987, food-equivalent composites representing the average food intake of each cohort at baseline were collected locally and analyzed in a central laboratory.

All analyses concern only intercohort comparisons.
Methods: In the baseline surveys carried out between 1958 and 1964, risk factors for coronary heart disease were measured among 12,763 middle-aged men constituting 16 cohorts in seven countries.
Objective: To determine whether flavonoid intake explains differences in mortality rates from chronic diseases between populations.
Design: Cross-cultural correlation study.
Setting/participants: Sixteen cohorts of the Seven Countries Study in whom flavonoid intake at baseline around 1960 was estimated by flavonoid analysis of equivalent food composites that represented the average diet in the cohorts.
Sixteen cohorts of men aged 40-59 years at entry were examined with the measurement of some risk factors and then followed-up for mortality and causes of death for 25 years. These cohorts were located in the USA (1 cohort), Finland (2), the Netherlands (1), Italy (3), the former Yugoslavia (5), Greece (2), and Japan (2), and included a total of 12,763 subjects. Large differences in age-adjusted coronary heart disease (CHD) death rates were found, with extremes of 45 per 1000 in 25 years in Tanushimaru, Japan, to 288 per 1000 in 25 years in East Finland.

A Cox model analysis of fatal coronary events over 15 years showed that serum cholesterol in men aged 40-59 years, cholesterol in men aged 45-64 years, and systolic blood pressure in men aged 50-69 played a predictive role. The coefficient of age became more significant with advancing age and that of cigarette smoking only at 25 years follow-up.

Large differences in 20-year death rates from stroke were recorded among cohorts, with the highest levels in the pool of the Yugoslavia (67 per 1000) and Japanese cohorts (62 per 1000) and the lowest in the Dutch cohort (22 per 1000). The simple linear correlation (among cohorts) of stroke mortality on mean levels at entry of some factors showed inverse significant coefficients for systolic (-0.

Risk factors for coronary heart disease were studied in healthy middle-aged Cretan men in order to compare them with the middle-aged men of a previous generation studied in 1960 as the Cretan cohort of the Seven Countries Study (1960). In the present cohort mean values for total cholesterol were 5.48 mmol/L, for HDL-cholesterol 1.
