Assessment of IL- 35 Gene Polymorphism in Periodontitis Patients with and without Diabetes - A Cross-Sectional Study.

Aim: To evaluate the IL-35 Gene Polymorphism in Periodontitis subjects with and without type 2 diabetes mellitus.

Methodology: 96 participants were categorized into three groups, Group 1: Systemically and Periodontally healthy individuals, Group 2: Systemically healthy patients with Generalized chronic periodontitis, Group 3: Generalized chronic periodontitis with type 2 diabetes Mellitus. Genomic DNA was extracted from the whole venous blood samples collected from the participants using The PureLink Genomic Kit.

Interventions to prevent the onset of frailty in adults aged 60 and older (PRAE-Frail): a systematic review and network meta-analysis.

Purpose: Frailty in older adults is associated with multiple adverse health outcomes, while evidence on its successful prevention has been scarce. Therefore, we analyzed the effectiveness of different interventions for the prevention of frailty onset.

Methods: In this systematic review, eight databases were searched for randomized controlled trials of interventions in non-frail (i.

Validation of a telephone-based administration of the simplified nutritional appetite questionnaire.

Background: Anorexia of aging is characterized by an age-associated reduction of appetite, whose aetiology in most cases is multifactorial and which often triggers malnutrition. The Simplified Nutritional Appetite Questionnaire (SNAQ) is an established screening tool. This study aimed to investigate reliability, validity, and feasibility of its telephone administration (T-SNAQ) in German community-dwelling older adults.

Multiple Genome Wide Association Mapping Models Identify Quantitative Trait Nucleotides for Brown Planthopper () Resistance in MAGIC Population of Rice.

Brown planthopper (BPH), one of the most important pests of the rice () crop, becomes catastrophic under severe infestations and causes up to 60% yield loss. The highly disastrous BPH biotype in the Indian sub-continent is Biotype 4, which also known as the South Asian Biotype. Though many resistance genes were mapped until now, the utility of the resistance genes in the breeding programs is limited due to the breakdown of resistance and emergence of new biotypes.

Emerging Concepts in Nutrient Needs.

Dietary reference intakes (DRIs) are quantitative, nutrient intake-based standards used for assessing the diets and specific nutrient intakes of healthy individuals and populations and for informing national nutrition policy and nutrition programs. Because nutrition needs vary by age, sex, and physiological state, DRIs are often specified for healthy subgroups within a population. Diet is known to be the leading modifiable risk factor for chronic disease, and the prevalence of chronic disease is growing in all populations globally and across all subgroups, but especially in older adults.

Folate nutrition and blood-brain barrier dysfunction.

Mammals require essential nutrients from dietary sources to support normal metabolic, physiological and neuronal functions, to prevent diseases of nutritional deficiency as well as to prevent chronic disease. Disease and/or its treatment can modify fundamental biological processes including cellular nutrient accretion, stability and function in cells. These effects can be isolated to a specific diseased organ in the absence of whole-body alterations in nutrient status or biochemistry.

Cleaner processing: a sulphide-free approach for depilation of skins.

The conventional unhairing process in leather making utilises large amount of lime and sodium sulphide which is hazardous and poses serious waste disposal concerns. Under acidic conditions, sodium sulphide liberates significant quantities of hydrogen sulphide which causes frequent fatal accidents. Further, the conventional unhairing process involves destruction of the hair leading to increased levels of biological oxygen demand (BOD), chemical oxygen demand (COD), total dissolved solids (TDS) and total suspended solids (TSS) in the effluent.

No effect of folic acid supplementation on global DNA methylation in men and women with moderately elevated homocysteine.

A global loss of cytosine methylation in DNA has been implicated in a wide range of diseases. There is growing evidence that modifications in DNA methylation can be brought about by altering the intake of methyl donors such as folate. We examined whether long-term daily supplementation with 0.

DNA methylation and cognitive functioning in healthy older adults.

Long-term supplementation with folic acid may improve cognitive performance in older individuals. The relationship between folate status and cognitive performance might be mediated by changes in methylation capacity, as methylation reactions are important for normal functioning of the brain. Although aberrant DNA methylation has been implicated in neurodevelopmental disorders, the relationship between DNA methylation status and non-pathological cognitive functioning in human subjects has not yet been investigated.

Genetic variation in folate metabolism is not associated with cognitive functioning or mood in healthy adults.

The present study examined the associations between genetic variation in folate metabolism on the one hand and cognitive functioning and mood on the other in healthy individuals. Two independent population-based samples were used, including 777 participants, aged 24-82 years, from the Maastricht Aging Study (MAAS); and 818 participants, aged 50-70 years, from the Folic Acid and Carotid Intima-Media Thickness (FACIT) study. Thymidylate synthase (TS) 2R→3R and serine hydroxymethyltransferase (SHMT1) 1420C→T polymorphisms were determined in both populations.

Effect of 3 y of folic acid supplementation on the progression of carotid intima-media thickness and carotid arterial stiffness in older adults.

Background: Observational studies have shown that low folate and elevated homocysteine concentrations are risk factors for vascular disease in the general population. Randomized controlled trials in vascular patients have failed to show that folic acid reduces the risk of recurrent vascular disease, whereas such trials are lacking in the general population.

Objective: The objective was to determine whether folic acid supplementation reduces the progression of atherosclerosis as measured by common carotid intima-media thickness (CIMT)-a validated marker of atherosclerosis and predictor of vascular disease risk.

Serum iron parameters, HFE C282Y genotype, and cognitive performance in older adults: results from the FACIT study.

Although iron homeostasis is essential for brain functioning, the effects of iron levels on cognitive performance in older individuals have scarcely been investigated. In the present study, serum iron parameters and hemochromatosis (HFE) C282Y genotype were determined in 818 older individuals who participated in a 3-year randomized, placebo-controlled double-blind trial examining the effects of folic acid on carotid intima-media thickness. All participants had slightly elevated homocysteine levels and were vitamin B12 replete.

Plasma very long-chain n-3 polyunsaturated fatty acids and age-related hearing loss in older adults.

Objectives: Age-related hearing loss is a common social and health problem in the older adult population. Up until now, very little scientific attention has been given to the potential role of fatty acids in age-related hearing loss. In this study we investigated whether plasma very long-chain n-3 polyunsaturated fatty acids (PUFAs) are associated with age-related hearing loss over three years.

Hemochromatosis (HFE) genotype and atherosclerosis: Increased susceptibility to iron-induced vascular damage in C282Y carriers?

Background: The C282Y mutation of the hemochromatosis (HFE)-gene increases body iron status. Among Caucasians, the carrier frequency of this mutation is 8-9%. C282Y carriers may be more susceptible to iron-induced atherosclerosis due to higher iron levels.

Methodological issues in primary prevention trials for neurodegenerative dementia.

The prevention of neurodegenerative dementias, such as Alzheimer's disease, is a public health priority. Due to the large numbers of affected patients, even interventions bringing about a relatively small delay in disease onset could have large public health effects. Randomized controlled trials (RCTs) are required to demonstrate the effectiveness of preventive interventions, but such trials raise specific methodological questions because they are new in the field of neurodegenerative diseases, and require large numbers of elderly subjects and lengthy follow-up periods.

Gender and body size affect the response of erythrocyte folate to folic acid treatment.

The recommended dietary allowance (RDA) differs between men and women for some vitamins, but not for folate. The RDA for folate is derived mainly from metabolic studies in women. We assessed if men differ from women in their response of erythrocyte folate to folic acid supplementation.

n 3 fatty acid proportions in plasma and cognitive performance in older adults.

Background: Very-long-chain n-3 polyunsaturated fatty acids (n-3 PUFAs) are suggested to be related to cognitive performance in older adults. However, limited data exist on the association between n-3 PUFAs and performance in specific cognitive domains.

Objective: We evaluated the association between plasma n-3 PUFA proportions and cognitive performance in 5 cognitive domains and determined whether plasma n-3 PUFA proportions predict cognitive change over 3 y.

Validation of a food frequency questionnaire to assess folate intake of Dutch elderly people.

Folate is required for 1-carbon metabolism and deficiency in folate leads to megaloblastic anemia. Low levels of folate have been associated with increased risk of vascular disease. To investigate whether RDA of folate are met, habitual folate intake needs to be assessed reliably.

Blood donation, body iron status and carotid intima-media thickness.

Iron could promote free radical formation, which may lead to injury of the arterial wall and atherosclerosis. Blood donation may reduce cardiovascular risk by lowering body iron status. We collected data on blood donation history and intima-media thickness of the common carotid artery (CIMT) in 819 subjects (50-70 years), who were recruited from municipal and blood bank registries in The Netherlands.

Effect of 3-year folic acid supplementation on cognitive function in older adults in the FACIT trial: a randomised, double blind, controlled trial.

Background: Low folate and raised homocysteine concentrations in blood are associated with poor cognitive performance in the general population. As part of the FACIT trial to assess the effect of folic acid on markers of atherosclerosis in men and women aged 50-70 years with raised plasma total homocysteine and normal serum vitamin B12 at screening, we report here the findings for the secondary endpoint: the effect of folic acid supplementation on cognitive performance.

Methods: Our randomised, double blind, placebo controlled study took place between November, 1999, and December, 2004, in the Netherlands.

Effects of folic acid supplementation on hearing in older adults: a randomized, controlled trial.

Background: Age-related hearing loss is a common chronic condition of elderly persons. Low folate status has been associated with poor hearing.

Objective: To determine whether folic acid supplementation slows age-related hearing loss.

Association of folate with hearing is dependent on the 5,10-methylenetetrahdyrofolate reductase 677C-->T mutation.

Vascular disease and its risk factors have been associated with the age-related hearing loss. We examined the association of elevated plasma homocysteine and its determinants with hearing levels. Pure-tone air conduction thresholds in 728 individuals with sensorineural hearing loss were not associated with homocysteine, erythrocyte folate and Vitamin B6.

Folate and the methylenetetrahydrofolate reductase 677C-->T mutation correlate with cognitive performance.

Low folate status has been associated with cognitive decline. We investigated the association of folate status and the 5,10-methylenetetrahydrofolate reductase (MTHFR) 677C-->T polymorphism with performance on a battery of neuropsychological tests. Furthermore, we investigated whether the association of folate with cognitive performance was mediated by plasma homocysteine or risk of vascular disease.
