Mecanismo genético da herança de resistência à Stemphylium solani e insensibilidade a sua fitotoxina em algodoeiro.
No full textA mancha preta do algodoeiro causada por Stemphylium solani ocorre em várias regiões produtora de algodão do Brasil, causando severos prejuízos em rendimento especialmente no Estado do Paraná (Mehta, 1998; Lima et al, 1997). O patógeno ataca apenas as folhas e as infecções de maçã e do colmo até agora não foram observadas. Recentemente, Mehta & Brogin (2000), reportaram que S. solani do algodoeiro produziu fitotoxina, ..

Association of Thyroid Stimulating Hormone and Lipid Profile in Pregnancy
No full textABSTRACT
Introduction: Thyroid hormones have significant functions in embryogenesis and fetal development. Evidence suggests that thyroid stimulating hormone (TSH) may exert extra-thyroidal effects and modify the profile of blood lipids.
Aim: To determine the association between maternal blood lipid profile and thyroid stimulating hormone in second and third trimester of pregnancy.
Methods & Materials: The present study was carried out at MGM Hospital, Navi Mumbai, India. 200 antenatal cases from October, 2012 to October 2014 were enrolled after taking an informed consent. The blood samples for Thyroid stimulating hormone and lipid profile were taken at 16th and 32nd weeks.
Results: The mean TSH level in second trimester was 1.53 mIU/L, with a standard deviation of 1.147 mIU/L. In third trimester, the mean TSH level was increased to 2.60 mIU/L with a standard deviation of 0.836mIU/L. The t-stat value was found to be -10.649 (p < 0.001). In third trimester, TSH was negatively correlated with Cholesterol (r= -0.214, p < 0.01) and VLDL (r= -0.148, p < 0.05). With increase in TSH level, cholesterol level will decrease.
Conclusion: TSH levels rises according to the gestational age, being higher in third trimester as compared to second trimester. There is a significant negative correlation between TSH levels and cholesterol & VLDL in third trimester of the pregnancy. Hence, TSH levels should be looked for, especially in third trimester, in order to keep the thyroid related problems in check.

Nonlinear properties of silicon core optical fibres
No full textSilica optical fibres are renowned for the framework they have set in modern communications systems, sensors, and biotechnology. One particular trend in current research aims to investigate materials with enhanced optical functionality, high optical efficiency, robustness, and a small device footprint. Amongst the many material choices, semiconductors are emerging as a promising route. In this work, optical fibres and semiconductors are elegantly unified to create a hybrid structure with the potential of seamless integration into current fibre infrastructures. Silica capillaries form the fibre templates in which amorphous semiconductor materials such as silicon and/or germanium are impregnated. This thesis will present the first comprehensive description of the fabrication, characterisation, and the implementation of silicon optical fibres for all-optical signal processing. The fibres are fabricated via a novel high pressure chemical deposition procedure. Each fibre is analysed to determine the exact material composition, uniformity, and more importantly the optical quality. Linear and nonlinear optical characterisations are performed experimentally and supported by intensive numerical studies to validate the results.The high nonlinearity of silicon is exploited for all-optical signal processing. Several investigations have been performed to determine key nonlinear coefficients that were previously unknown in these fibres. Nonlinear absorption experiments allowed for the determination of the degenerate and non-degenerate two-photon absorption coefficients, free carrier cross sections, and free carrier lifetimes of a number of silicon fibres. Nonlinear refraction investigations were then used to establish the Kerr nonlinearity. The strength of this parameter allowed for demonstration of strong self-phase and cross-phase modulation effects. With the insight gained in nonlinear absorption and refraction in silicon optical fibres, all-optical amplitude modulation and wavelength switching was demonstrated at ultrafast sub-picosecond speeds
Acute dialysis quality initiative (ADQI)
No full textA new star is born. Its name is ADQI which stands for Acute Dialysis Quality Initiative. In the firmament of guidelines and directions for appropriate management of renal diseases, little has been done so far concerning acute renal failure and its treatment. For this reason we felt that a process seeking consensus and evidence-based statements in the field of acute renal failure was needed
Respiratory muscle aids to avert respiratory failure and tracheostomy: a new patient management paradigm
No full textAn April 2010 consensus of clinicians from 22 centers in 18 countries reported 1,623 spinal muscular atrophy type 1, Duchenne muscular dystrophy, and amyotrophic lateral sclerosis noninvasive intermittent positive pressure ventilatory support users, of whom 760 developed continuous dependence that prolonged their survival by more than 3,000 patient-years without tracheostomies. Four of the centers routinely extubated unweanable patients with Duchenne muscular dystrophy, so that none of their more than 250 such patients has undergone tracheotomy. This article describes the manner in which this is accomplished; that is, the use of noninvasive inspiratory and expiratory muscle aids to prevent ventilatory failure and to permit the extubation and tracheostomy tube decannulation of patients with no autonomous ability to breathe (ie, who are “unweanable” from ventilator support). Noninvasive airway pressure aids can provide up to continuous ventilatory support for patients with little or no vital capacity and can provide for effective cough flows for patients with severely dysfunctional expiratory muscles.Peer reviewe
