Saving a hopeless tooth with a four-wall bone defect: A case report.

Background: Recombinant human fibroblast growth factor-2 (rhFGF-2) has been shown to effectively promote the formation of new periodontal tissues, and its efficacy has been demonstrated in clinical settings. Moreover, the clinical and radiographic outcomes in the treatment of periodontal infrabony defects can be improved by using rhFGF-2 in combination with a bone substitute. Here, we present a case of four-wall bone defect in a tooth treated by combination regenerative therapy using rhFGF-2 and beta-tricalcium phosphate (β-TCP).

Brain-derived neurotrophic factor promotes bone regeneration in a canine model of peri-implantitis.

Purpose: The present study aims to determine whether the brain-derived neurotrophic factor (BDNF)/high-molecular-weight hyaluronic acid (HMW-HA) complex could regenerate bone around implants lost due to peri-implantitis.

Methods: Dogs had their three premolars extracted, and three implants were placed on each side. After osseointegration, 3-0 silk threads were ligated around the healing abutment for 12 weeks.

Effects of Low-Dose Tadalafil in a Patient with Biventricular Heart Failure: A Case Report.

Phosphodiesterase type 5 (PDE5) inhibitors such as tadalafil, can improve cardiac output by increasing left ventricular preload; however, there are concerns that this can increase the risk of heart failure due to pulmonary congestion in patients with elevated left ventricular end-diastolic pressure. We encountered a case in which low dose tadalafil improved the hemodynamics of a 66-year-old male patient with dilated cardiomyopathy (DCM) with congestion and low cardiac output due to biventricular dysfunction. The patient received a cardiac resynchronization therapy defibrillator (CRT-D) and appropriate medical therapy for heart failure.

Involvement of Rac1 in macrophage activation by brain-derived neurotrophic factor.

Brain-derived neurotrophic factor (BDNF) enhances periodontal tissue regeneration. Tissue regeneration is characterized by inflammation, which directs the quality of tissue repair. This study aimed to investigate the effect of BDNF on the phagocytic activity of RAW264.

Trends in nutritional intake and coronary risk factors over 60 years among Japanese men in Tanushimaru.

We investigated the relationship between time trends in nutrient intake and coronary risk factors/mortality rates in Tanushimaru, a Japanese cohort of the Seven Countries Study. All men between the ages of 40 and 64 were enrolled. Subjects numbered 628 in 1958, 539 in 1977, 602 in 1982, 752 in 1989, 402 in 1999, 329 in 2009, and 160 in 2018.

Habitual coffee intake reduces all-cause mortality by decreasing heart rate.

It is well known that subjects with metabolic syndrome show an elevated resting heart rate. We previously reported that elevated heart rate was significantly related to all-cause mortality, and that coffee consumption was inversely associated with metabolic syndrome. We hypothesized that higher coffee consumption may decrease all-cause mortality by reducing resting heart rate.

Association between physical activity, occupational sitting time and mortality in a general population: An 18-year prospective survey in Tanushimaru, Japan.

Aims: It is well known that a decline in physical activity is associated with an increase of all-cause death including cardiovascular events and cancer. Few studies have examined the association between occupational sitting time and mortality. Therefore, we investigated this issue in a general population.

Twenty-four-Hour Urinary Potassium Excretion, But Not Sodium Excretion, Is Associated With All-Cause Mortality in a General Population.

Background: Few studies have examined the relationship between accurate monitoring of sodium or potassium consumption and mortality. We aimed to investigate the association between 24-hour urinary sodium or potassium excretion and ≈30-year mortality in a Japanese population using 24-hour urine collection.

Methods And Results: We enrolled a total of 1291 participants, aged 21 to 85 years, who underwent health checkups, including a blood test and 24-hour urine collection.

Impact of cystatin C and microalbuminuria on cognitive impairment in the population of community-dwelling Japanese.

Background And Aims: Cognitive impairment is an important element affecting our well-being, and as such, early diagnosis is critical today. We investigated whether serum cystatin C and microalbuminuria are associated with cognitive impairment.

Methods: A total of 1943 subjects (774 males, 1169 females, mean age 65.

Elevated Plasma Transforming Growth Factor β1 Levels Predict the Development of Hypertension in Normotensives: The 14-Year Follow-Up Study.

Background: Transforming growth factor β1 (TGF-β1) is a multifunctional cytokine. There is growing evidence that TGF-β1 is involved in the pathogenesis of hypertension and the development of target organ damage in hypertensives. Although several studies have shown that TGF-β1 induced vascular hypertrophy and remodelling in various vascular diseases, there are no longitudinal data on hypertension in the epidemiological studies.

Trends in coronary risk factors and electrocardiogram findings from 1977 to 2009 with 10-year mortality in Japanese elderly males - The Tanushimaru Study.

Background: An understanding of the trends in regard to coronary risk factors and electrocardiogram (ECG) findings has an important role in public health. We investigated the trends in coronary risk factors and main ECG findings in 1977, 1989, 1999, and 2009 in the Japanese cohort of the Seven Countries Study, in Tanushimaru, a typical farming town on Kyushu Island.

Methods And Results: A total of 1397 subjects (231 in 1977, 332 in 1989, 389 in 1999, and 445 in 2009) were enrolled in this study, and all of them were males aged over 65 years.

Augmentation index (AI) in a dose-response relationship with smoking habits in males: The Tanushimaru study.

We investigated the relationship between augmentation index (AI) and smoking habits in community-dwelling Japanese.This cross-sectional study enrolled 1926 subjects (769 males and 1157 females) aged 40 to 95 years who underwent a health check-up in a Japanese cohort of the Seven Countries Study, in Tanushimaru, a typical farming town in Kyushu Island in 2009. The subjects' medical history, alcohol intake, smoking habit, and current medications for hypertension, dyslipidemia, and diabetes were ascertained by questionnaire.

The ecological perspective of microbial communities in two pairs of competitive Hawaiian native and invasive macroalgae.

Marine macroalgae are known to harbor large populations of microbial symbionts, and yet, microbe symbiosis in invasive macroalgae remains largely unknown. In this study, we applied molecular methods to study microbial communities associated with two invasive algae Acanthophora spicifera and Gracilaria salicornia and the two native algae Gracilaria coronopifolia and Laurencia nidifica at spatial and temporal scales in Hawaiian coral reef ecosystems. Bacterial communities of both the invasive and native macroalgae displayed little spatial and temporal variations, suggesting consistent and stable bacterial associations with these macroalgae.
