Plant Growth Promoting Rhizobacteria 总被引:1,自引:0,他引:1

Plant Growth Promoting Rhizobacteria (PGPR) are a group of bacteria that enhances plant growth and yield via various plant growth promoting substances as well as biofertilizers. Given the negative environmental impact of artificial fertilizers and their increasing costs, the use of beneficial soil microorganisms such as PGPR for sustainable and safe agriculture has increased globally during the last couple of decades. PGPR as biofertilizers are well recognized as efficient soil microbes for sustainable agriculture and hold great promise in the improvement of agriculture yields. 相似文献

This phenomenological study investigated the experiences of 8 Black students enrolled in a master's‐level counseling program. Five themes central to participant experiences were identified: (a) isolation as a Black student, (b) tokenization as a Black student, (c) lack of inclusion of Black counselor perspectives within course work, (d) differences between support received by faculty of color and support received by White faculty, and (e) access to support from people of color and White peers. Implications for counselor educators and study limitations are discussed. 相似文献

This paper reports a study of the accounts of pedagogic work provided by Samoan paraprofessionals responsible for forging lines of communication between government secondary schools in an Australian city and state-designated disadvantaged local communities. The paraprofessionals are viewed as representatives of the imagined communities constructed around schools in official state discourses on educational disadvantage and equality. It is shown that the discourses on Samoan pedagogy spoken by the paraprofessionals are appropriated from a highly conflictual field of anthropological and historical knowledge-production. Qualitative analysis of interview data provided by the paraprofessionals indicates that all interviewees emphasized differences in the form and content of pedagogy between the Australian school and the Samoan home and church, attributing these differences to various relations of power and control. In conclusion, it is proposed that the paraprofessionals' accounts should not be read as simply true or untrue, but in terms of their specificity as input to institutional pedagogic work-input with the potential to bring cultural difference into being as it is acted on by teachers and other educational agents. 相似文献

The case study illustrates another genre of the B2E (business to employee) model, implemented at a large Indian IT organisation to engage its employees in order to create value for its customers. The main focus of the empirical analysis is the counterintuitive strategy to ensure customer loyalty and increased revenues by transforming the relationship between the management and the employees. A brief outline is presented of the B2E model and a case analysis of issues is derived. 相似文献

Neural tube defects are congenital structural abnormalities of the brain and vertebral column resulting from improper or non-timely
closure of the neural tube. Prevalence of neural tube defects is reported to be higher among women with diabetes mellitus
and obesity. This study was designed to investigate the relation between the presence of dyslipidemia in antenatal patients
and the risk of fetal neural tube defects. The present study was an observational, cross-sectional study involving 129 pregnant
women in 16 to 18 weeks gestation period. Of these, 80 women had normal pregnancies and 49 were clinically high-risk cases
for neural tube defects. Fasting blood samples were analyzed for blood sugar and lipid profile by enzymatic assay and alpha-fetoprotein
levels using Enzyme Immunoassay. Alpha-fetoprotein (AFP) values were converted to Multiples of Median (MoM) appropriate for
the gestational age. Based on AFP values, women were labeled as screen negative (AFP <2 MoM, n= 102) and screen positive (AFP
> 2 MoM, n =27). Screen positive women were further evaluated by ultrasound and 21 women were found to carry a neural tube
defects positive pregnancy. Statistical analysis was done on SPSS software. Body weight of the women showed a significant
positive correlation with serum triglycerides, plasma sugar and AFP MoM values. A significant difference was observed in serum
cholesterol levels (p= 0.038), triglycerides (p=0.001) and plasma sugar levels (p=0.002) between normal women and those with
neural tube defects positive pregnancy. The Odds ratio for neural tube defects risk in dyslipidemic cases was 24.23 (CI 4.73
− 148.60) with a relative risk of 12.12. Dyslipidemia especially hypertriglyceridemia was found to be significantly associated
with fetal neural tube defects. 相似文献

Aqueous and alcoholic extracts of amalki (Emblica officinalis), spirulina and wheatgrass were prepared and analyzed for antioxidant
vitamin content (vitamin C and E), total phenolic compounds. Antioxidant status, reducing power and effect on glutathione
S-transferase (GST) activity were evaluated in vitro. Vitamin C content of crude amalaki powder was found to be 5.38 mg/g,
while very less amount 0.22 mg/g was detected in wheat grass. Amalki was rich in vitamin E like activity, total phenolic content,
reducing power and antioxidant activity. Total antioxidant activity of aqueous extract of amalki, spirulina and wheat grass
at 1mg/ml concentration were 7.78, 1.33 and 0.278 mmol/l respectively. At similar concentrations the total antioxidant activity
of alcoholic extract of amalaki, spirulina and wheat grass was 6.67, 1.73 and 0.380 mmol/l respectively. Amalki was also found
to be rich source of phenolic compounds (241mg/g gallic acid equivalent). Alcoholic extract of wheat grass showed 50 % inhibition
in FeCl2- ascorbic acid induced lipid peroxidation of rat liver homogenates in vitro. Both aqueous and alcoholic extracts of amalaki
inhibited activity of rat liver glutathione S-transferase (GST) in vitro in dose dependant manner. Since GST acts as powerful
drug metabolizing enzyme its inhibition by amalaki offers possibility of its use for lowering therapeutic dose of herbal preparations.
The aqueous extracts of both amalki and spirulina also showed protection against t-BOOH induced cytotoxicity and production
of ROS in cultured C6 glial cells. 相似文献

Blood glutathione was estimated in fifty patients of head and neck cancer in the age group of 18–76 years and the results
were compared with a group of normal healthy controls. Mean blood glutathione level was found to be significantly lowered
in patients than the controls. Irrespective of the site, TNM classification, histopathology, and character of lesion, fall
in blood glutathione was nearly same in all the patients. The mean level was significantly increased after radiotherapy when
compared with the levels before radiotherapy. The decreased levels of GSH in-patients with head and neck cancer, observed
in the present study, may be due to its increased utilization by the cells. The results suggest that patients with head and
neck cancer have increased oxidative stress. 相似文献

Effect of irbesartan, an angiotensin II receptor antagonist, was studied in streptozotocin (STZ) induced diabetic nephropathy.
Polyuria, proteinuria, blood urea, creatinine clearance, and urinary electrolytes were determined to assess kidney damage.
There was a significant increase in urine volume, urinary protein and blood urea in STZ induced diabetic rats. On the other
hand, irbesartan treatment resulted in a significant reduction in urinary protein and blood urea in these rats. Irbesartan
treatment also improved creatinine clearance and exhibited a natriuretic effect in these animals. Results suggest that irbesartan
treatment ameliorate STZ induced diabetic nephropathic changes, in rats. 相似文献
