PdP/WO3 multi-functional catalyst with high activity and stability for direct liquid fuel cells (DLFCs)
Direct liquid fuel cells are energy conversion devices which utilize formate and methanol as fuels. These systems are relieved of the problem of H2transport and storage, making them highly desirable for various practical applications. However, the low stability and activity of carbon supported catalysts such as Pt/C both in the anode and cathode is a critical hindering factor towards their further development. As a practical solution to overcome this issue, in this work, we report on the development of phosphorus-doped palladium (PdP) nanoparticle-supported tungsten oxide (WO3) nanorods (PdP/WO3) as a versatile multifunctional catalyst for facilitating the oxidation of formate and methanol in the anode and the oxygen reduction reaction (ORR) in the cathode. Strong metal-support interactions and electronic modifications incurred by the doped phosphorus help this system to achieve desirable properties to enable it to effectively function both for the anode and cathode applications. PdP/WO3showed 16-times higher mass activity compared to Pt/C even after 3000 start/stop cycles for the ORR. For formate and methanol oxidation, PdP/WO3exhibited current densities of 0.50 and 0.734 A mgPd−1, respectively, outperforming thestate-of-the-artcatalysts. With these bifunctional features, PdP/WO3stands out as a potential system to be used as an anode and cathode catalyst in direct liquid fuel cells, all the while offering an opportunity for the development of carbon-free electrocatalysts
A Survey on: Hyper Spectral Image Segmentation and Classification Using FODPSO
The Spatial analysis of image sensed and captured from a satellite provides less accurate information about a remote location. Hence analyzing spectral becomes essential. Hyper spectral images are one of the remotely sensed images, they are superior to multispectral images in providing spectral information. Detection of target is one of the significant requirements in many are assuc has military, agriculture etc. This paper gives the analysis of hyper spectral image segmentation using fuzzy C-Mean (FCM)clustering technique with FODPSO classifier algorithm. The 2D adaptive log filter is proposed to denoise the sensed and captured hyper spectral image in order to remove the speckle noise
Hyper Spectral Image Segmentation and Classification Using Least Square Clustering Based on FODPSO
The spatial analysis of the image detected and acquired by a satellite provides less accurate information on a remote location. Hyperspectral images are one of the images detected remotely, they are superior to multispectral images that provide spectral information. detailed information is one of the important requirements in many areas, such as military, agriculture, etc. The FODPSO classifier algorithm is used with the grouping technique of least squares for image segmentation. The 2D adaptive filter is proposed to eliminate the noise of the hyperspectral image detected and captured in order to eliminate the noise of the spot. Denoising the hyperspectral image (HSI) is an essential pre-processing step to improve the performance of subsequent applications
POLYCYSTIC OVARY SYNDROME: PATHOGENESIS, TREATMENT AND SECONDARY ASSOCIATED DISEASES
Polycystic ovary syndrome (PCOS) is the most common endocrinopathy in women of reproductive age. It is characterized by hyperandrogenism, polycystic ovaries, and chronic anovulation along with insulin resistance, hyperinsulinemia, abdominal obesity, hypertension, and dyslipidemia as frequent metabolic traits (metabolic syndrome) that culminate in serious long-term consequences such as type 2 diabetes mellitus, endometrial hyperplasia, and coronary artery disease. It is one of the most common causes of anovulatory infertility. A complete understanding of the underlying Pathophysiology of PCOS is still lacking. Because of the heterogeneity of this disorder, there are most likely multiple underlying pathophysiologic mechanisms. Pathogenesis of PCOS is explaining as alteration in gonadotropin-releasing hormone secretion results in increased luteinizing hormone (LH) secretion. An alteration in insulin secretion and insulin action results in hyperinsulinemia and insulin resistance. A defect in androgen synthesis that results in increased ovarian androgen production.Treatment of PCOS include maintaining a normal endometrium, antagonizing the actions of androgens on target tissues, reducing insulin resistance (when present), and correcting anovulation. Women with polycystic ovary syndrome (PCOS) are at higher risk for several other health conditions as Insulin Resistance, Metabolic Syndrome, Type 2 Diabetes, Obesity, Heart Disease and High Blood Pressure (Cardiovascular Disease)
 
Factors influencing the work performance of Mitanins (ASHA) in Bilaspur district, Chhattisgarh, India: a cross sectional study
Background: The Mitanin programme is a community health volunteer programme which was initiated by the Government of Chhattisgarh, India in 2002. The Mitanin programme further progressed to lay foundation for the Accredited Social Health Activists (ASHA) programme by the National Rural Health Mission. There is robust indication that the Community health workers could significantly contribute towards the betterment of health outcomes. The objective of the study was to study the factors influencing the work performance of Mitanins in Bilaspur district, Chhattisgarh, India.Methods: A community based cross sectional study was carried out among 180 Mitanins selected through multistage random sampling in Bilaspur district, Chhattisgarh, India during March to August 2015. A predesigned, pretested questionnaire was used for data collection.Results: Regarding counselling to pregnant mother on maternal and child health about (65.6%) Mitanins were having knowledge and out of these prevalence of its practice was found to be (75.4%). Their less knowledge for content of responsibility significantly affected their practices in community. Other major factors influencing their work performance are better training sessions (37.8%), support from health staff (65.6%), drug kit refilling (80%), and fewer hurdles in receiving incentives (85.6%.Conclusions: Less knowledge of the work component, less cooperation from health staff, delay refilling of drug kit, incentive oriented practices, delayed and inadequate payment of incentives for Mitanins influences the work performance

Cardio-renal syndromes: report from the consensus conference of the Acute Dialysis Quality Initiative
A consensus conference on cardio-renal syndromes (CRS) was held in Venice Italy, in September 2008 under the auspices of the Acute Dialysis Quality Initiative (ADQI). The following topics were matter of discussion after a systematic literature review and the appraisal of the best available evidence: definition/classification system; epidemiology; diagnostic criteria and biomarkers; prevention/protection strategies; management and therapy. The umbrella term CRS was used to identify a disorder of the heart and kidneys whereby acute or chronic dysfunction in one organ may induce acute or chronic dysfunction in the other organ. Different syndromes were identified and classified into five subtypes. Acute CRS (type 1): acute worsening of heart function (AHF–ACS) leading to kidney injury and/or dysfunction. Chronic cardio-renal syndrome (type 2): chronic abnormalities in heart function (CHF-CHD) leading to kidney injury and/or dysfunction. Acute reno-cardiac syndrome (type 3): acute worsening of kidney function (AKI) leading to heart injury and/or dysfunction. Chronic reno-cardiac syndrome (type 4): chronic kidney disease leading to heart injury, disease, and/or dysfunction. Secondary CRS (type 5): systemic conditions leading to simultaneous injury and/or dysfunction of heart and kidney. Consensus statements concerning epidemiology, diagnosis, prevention, and management strategies are discussed in the paper for each of the syndromes
Study of sternalis muscle in north Indian population- a cadaveric study
Background: Sternalis is anatomic variant of anterior thoracic region generally encountered on routine dissection, imaging procedures or surgeries. Although here is sufficient text available regarding presence and extent of sternalis muscle but state of confusion still exist regarding its nerve supply.
Aim: In our study we have tried to find out the incidence of presence of sternalis muscle in north Indian population and through fine dissection, we have focused on the innervation received by the muscle.
Materials and Method: 48 human cadavers including both male and female were dissected at Veer Chandra Singh Garhwali Government Institute of medical Science & Research, Paui- Garhwal and Sarojini naidu Medical College Agra. Special emphasis was laid on innervations and through fine dissection, detailed picture about innervations was recorded. For cases with doubt, histological examination was done and final observations were recorded.
Result: Sternalis muscle was reported in 4 out of 48 cadavers. All cases presented with unilateral type of sternalis muscle. Three were present in male while one in female cadaver. In one cadaver, it was innervated by medial pectoral nerve while in two, innervations were provided by intercostals group of nerves. Only one cadaver presented with dual nerve supply.
Conclusion: in north Indian region, incidence of sternalis is 8.3 percent with dual innervation in single cadaver
Vitamin D Dependent Rickets Type II: Late Onset of Disease and Response to High Doses of Vitamin D
Vitamin D dependent rickets Type II is a rare autosomal recessive disorder. The disorder is characterized by end organ hyporesponsiveness to vitamin D. Common presentation of the disorder is total body alopecia and onset of rickets during the second half of the first year of life. Patients may display progressive rachitic bone changes, hypocalcemia and secondary hyper-parathyroidism. It is differentiated from vitamin D dependent rickets type I by virtue of response to physiological doses of exogenous vitamin D in the later. Target organ hyporesponsiveness can be overcome by higher doses of vitamin D or its analogues. We report a case of vitamin D dependent rickets type II with onset of rickets at the age of thirteen years without alopecia progressing to marked disability by twenty three years of age. She responded to massive doses of vitamin D with significant clinical improvement after six months of therapy
