Abstract: Rhizobacteria is a prosperous for promoting plant growth for the superiority of reducing environmental damages. Two Strains of Chlorobium limicola and Rhodopseudomonas palustris were supplied in the experiment as potential inoculants for cucumber. Significant enhancement of the availability of macronutrient elements N, P and K were observed in soil, and further improvement on the uptake of them was also obtained in cucumberplants. Accumulation of essential micronutrients of Fe and Zn were detected both in roots and in shoots. The two stains increased chlorophylland carotinoid synthesis, plant height, stem diameter, wet weight and dry weight. Various dose has significantly effect on plant growth stimulation, C. Limicola with 107 cells mL-1 and R. Palustris with 108 cells mL-1 seem to be better on the whole. Keywords: Biofertilizer, cucumber, growth, nutrien.Download Full Article |
Abstract : Biomolecule Damage (DNA and Lipid) is Elevated in Patients with Type 1 Diabetes with and without Diabetic Complications

Abstract: There is strong evidence that oxidative stress is involved in the aetiology and pathogenesis of diabetes and its complications. Increased production of reactive oxygen species in vivo can lead to cellular biomolecule damage, such as lipid peroxidation and DNA damage. The aim of this study was to determine the extent of this damage by measuring in vivo antioxidant status, levels of lipid peroxidation, and levels of neutrophil DNA damage in 50 participants with type 1 diabetes and 50 age- and sex-matched, healthy controls. Gylcaemic control (%HbA1c) was relatively good with a group mean of 7.71% which increased to 8.12 % in those with complications. Compared to the control group there were significantly elevated levels of neutrophil DNA damage (% tail DNA, p<0.0001) and plasma MDA levels (p<0.05) in the Type 1 group as a whole, this significance rose to p<0.01 in those with complications. There were significant alterations in markers of antioxidant status including, reduced levels of superoxide dismutase (p<0.0001), uric acid (p<0.05) and Vitamin C (p<0.05) and elevated levels of catalase (p<0.001). These results indicate that even with acceptable glycaemic control significant oxidative damage still occurs and this damage increases, in some indices, with the onset of complications. Keywords: DNA damage, Type 1 Diabetes, Lipid damage, Glycaemic control, oxidative stress. |

Abstract: Physical inactivity, overweight, and obesity are serious issues plaguing the American public. The extent to which regular yoga participation may be associated with the adoption and maintenance of health enhancing behaviors necessitates further investigation. Through a mixed method of inquiry, this study investigated the exercise and eating habits of adults who participate in yoga on a regular basis exploring facets of mindful eating, exercise habits, and body mass index. Survey packets were distributed across seven yoga studios and fitness facilities in central New Jersey; 87 adults with a mean age of 47 years self-selected to participate. Quantitative and qualitative data were collected including a Mindful Eating Questionnaire, a 7-Day Physical Activity Recall, height and weight, yoga tenure recorded in months/years of consistent yoga participation, and average daily fruit and vegetable intake. Results showed thatmindful eating was inversely correlated with Body Mass Index (BMI) and that 72% of the yoga participants had a BMI of 24.9 or less, placing them in the normal weight category. A significant difference existed in mindful eating score relative to yoga tenure and vegetable and fruit intake relative to yoga tenure. Participants reported a mean of 239 minutes of weekly exercise other than yoga participation. Qualitative data were collected throughtwo open-ended questions to ascertain the participants’ perceptions of yoga and their health-related behaviors; the data revealed that 87% of participants felt yoga enhanced their exercise adherence and 91% reported yoga promoted the adoption of positive health habits. The results suggest that yoga participation is associated with mindful eating and the adoption and maintenance of other positive health-related outcomes such as regular physical activity and weight management.

Abstract : The Dietary Intakes of Calcium and Bone Health Related Nutrients Among Individuals with and without Spinal Cord Injury

Abstract: Objectives: The purposes of this observational study were to: 1) describe and compare the intakes of nutrients related to bone health among a group of individuals with traumatic spinal cord injury (SCI) versus a group of age, gender and weight matched non–SCI peers; and 2) contrast the participant’s nutrient intakes against current dietary reference intakes (DRIs). Methods: Consenting participants included: 87 individuals with SCI (C2-T10 AIS A-D) aged 18-68 years and 85 non-SCI individuals. Participants’ nutrient intakes were determined using a 24-hour dietary recall. Participants were grouped by gender, age (19-30yrs, 31-50yrs, 51-68yrs), and impairment (SCI and non-SCI). Additionally, the nutrient intakes were contrasted with the DRIsparameters.
Results: The range for mean calcium intakes across all age strata was 870-1087mg/day for SCI men and 848-1087mg/day for SCI women. The range for mean calcium intakes of the non-SCI participants were similar (men: 900-909mg/day; women: 796-1160mg/day). The majority of SCI and non-SCI men (64 - 86% of participants) in all age groups and SCI and non-SCI women in the 52-68 yrs group (72 and 73% of participants) did not meet the DRIs recommendation for calcium.. Additionally many participants did not meet the DRIs recommendation for magnesium (38-55%) and potassium (71-95%) regardless of gender and impairment. The majority (60-70%) of participants consumed excessive amounts of sodium with the exception of non-SCI women.
Conclusions: Dietary calcium intakes among SCI and non-SCI participants were not significantly different from each other. However, the dietary calcium intakes of both impairment groups were less than the recommended DRIs; SCI men and women are a target for nutritional interventions based on their calcium, magnesium potassium and sodium intakes.

Abstract: Aims:The specific aim of this review was to compile the first systematic review of systematic reviews and meta-analyses from a range of studies that evaluates the evidence that elevated homocysteine may be a risk factor for CVD. Data Synthesis:379 entries were identified by initial screening using set criteria revealing eleven meta-analyses, one systematic review, two systematic reviews/meta-analyses and ten other studies, between 1994 and 2013.These studies compared homocysteine levels and its relationship with twelve different types of CVD chronic conditions. Final methodological quality assessment was conducted independently using the instrument AMSTAR for the systematic reviews and meta-analyses. The remaining studies were assessed using data extraction tools from JBI QARI, Appendix 2 & 4 packages. Conclusions:From the selected studies, 82.8% of the CVD conditions demonstrated that epidemiologic and clinical data strongly indicated that elevated homocysteine levels is a risk factor for primary CVD. 71.4% of the CVD conditions demonstrated that plasma tHcy can be employed as an independent biomarker. Despite 46.2% of the CVD conditions finding that reducing plasma tHcy lowers the risk of many CVD events, it remains unclear whether the reduction in plasma tHcy will reduce the risk of some CVD events; it is therefore considered prudent to take precautionary measures to aim for normal levels of homocysteine to avoid the risk of developing or exacerbating CVD. Moreover, it was shown that levels of homocysteine can be profoundly affected by diet, supplementation and lifestyle. The present study will help to clarify the present scientific understanding of this subject. Keywords: Hyperhomocysteinemia, cardiovascular disease, metabolism, diet, lifestyle.Download Full Article |
