Evaluation of Syncope: An Overview

Syncope is defined as a sudden temporary loss of consciousness associated with a loss of postural tone, with spontaneous recovery that does not require electrical or chemical cardioversion. Syncope is a common symptom, accounting for 1% to 6% of hospital admission and up to 3% of emergency room visits. Loss of consciousness is also common in healthy young adults, although most do not seek medical attention. Syncope is a frequent symptom in the elderly. The evaluation and management of syncope has dramatically changed over the past 15 years. In the early 1980s, several studies showed that the cause of syncope was often not established, and subgroups were identified with high mortality and sudden death rates.1,2 ,3, 4 Later a large number of studies on electrophysiology testing appeared, which led to a better understanding of the roles and limitations of tests in syncope.5,6,7,8 Although tilt table testing started in 1980s, it assumed an important role in the evaluation of syncope in 1990s, showing that neurally mediated mechanism is a common etiology of unexplained syncope.9,10,11,12 The purpose of this article is to highlight the clinical approach and management of syncope

PATHYA APATHYA: IMPACT AND ROLE IN LIFESTYLE DISORDERS

Ayurveda is an ancient and most trusted Indian system of medicine commonly used by Indians since time immemorial. Lifestyle diseases/ Metabolic diseases are described as diseases related to the way an individual or group of individuals live, also are referred under Non-Communicable Diseases. Over-crowding and rapid unplanned urbanization; globalization of unhealthy lifestyles is responsible for some of the major reasons for a sedentary life leading to these diseases. It includes arteriosclerosis, heart disease, stroke, obesity and type-2 diabetes, diseases related to smoking, alcohol and drug abuse. The contribution of metabolic risk factors such as high blood pressure, blood sugar, cholesterol and that of improper diet and alcohol use resulting in health loss. Therefore, the occurrence of these disorders has doubled in India over the past quarter of a century therefore it is the need of the hour to manage them diligently. Diet plays a key role to nourish life and balanced diet is very important for maintaining good health. In Ayurveda, wholesome diet is described which plays a very important role specifically rather than in modern medicine which emphasizes only on the components in the diet like proteins, carbohydrates, fats etc. Ayurveda additionally deals with various other aspects like combination of food article, their quantity, method of preparation, their emotional effect, nature of consumer including environmental considerations. Pathya and Apathya Ahara (dietary consideration) is a significant component of almost each and every prescription in Ayurveda therapy. Sometimes, Pathya-Apathya (dietary management) is itself an entire treatment

A review of action of commonly used antihypertensive drugs in Ayurveda with special reference to Samprapti Vighatana

Hypertension stands as a disease of high mortality owing to being a major risk factor for cardiovascular diseases, stroke and kidney diseases. Treatment modalities of modern medical science do not have enough efficacies in reducing target organ damage and they have adverse effects as well. So global attention is diverted towards the Ayurveda for safe, effective and economical remedies. A number of Ayurvedic herbs are being used since time immortal to treat hypertension based on the factors involved in the Pathogenesis. So it is the need of the time to validate the claims of antihypertensive herbs on modern parameter regarding its safety and efficacy. This study is made with an aim to review the various studies done on commonly used antihypertensive herbs and their role in breaking the pathogenesis. The various pathological mechanisms contributing the manifestation of hypertension and recent study on antihypertensive herbs are compiled by going through texts, journals and internet search. The obtained data are reviewed critically to understand the actions of herbs in Samprapti Vighatana of Hypertension. It is found that the hypertension is a disorder of Vaata Dosha due to Aavarana. The causative factors are Santarpanajanya Nidaan. The various other factors involved in the manifestation of Hypertension are Rasavaha, Raktavaha, Medovaha and Manovaha Srotas. The treatment of Hypertension should be done with targeting these factors with proper assessment of strength of disease and disesed

Recent technologies for transforming textile waste into value-added products:A review

The disposal of textile waste has become a growing issue worldwide. The rising consumption of clothing and textile materials has resulted in high waste generation. This could adversely impact environmental health, including humans, animals and plants. The three textile recycling methods can be divided into mechanical, chemical, and biological processes. There has been a focus on mechanical and chemical processes, pyrolysis, enzymatic hydrolysis, biological recycling, and microbial engineering in the area of textile waste managment. This review highlight the important parameters that affect the textile recycling performance and are significant for the success of the transformation process. To reach the zero-waste goal, textile recycling and converting this waste into value-added bioproducts are the necessary steps. The present review addresses the current status of textile recycling strategies, and the valorisation processes for converting textile waste materials into value-added products like biofuels, bioplastics, and others sustainable materials.</p

Nanocolumnar Crystalline Vanadium Oxide-Molybdenum Oxide Antireflective Smart Thin Films with Superior Nanomechanical Properties

Vanadium oxide-molybdenum oxide (VO-MO) thin (21-475 nm) films were grown on quartz and silicon substrates by pulsed RF magnetron sputtering technique by altering the RF power from 100 to 600 W. Crystalline VO-MO thin films showed the mixed phases of vanadium oxides e.g., V2O5, V2O3 and VO2 along with MoO3. Reversible or smart transition was found to occur just above the room temperature i.e., at similar to 45-50 degrees C. The VO-MO films deposited on quartz showed a gradual decrease in transmittance with increase in film thickness. But, the VO-MO films on silicon exhibited reflectance that was significantly lower than that of the substrate. Further, the effect of low temperature (i.e., 100 degrees C) vacuum (10(-5) mbar) annealing on optical properties e.g., solar absorptance, transmittance and reflectance as well as the optical constants e.g., optical band gap, refractive index and extinction coefficient were studied. Sheet resistance, oxidation state and nanomechanical properties e.g., nanohardness and elastic modulus of the VO-MO thin films were also investigated in as-deposited condition as well as after the vacuum annealing treatment. Finally, the combination of the nanoindentation technique and the finite element modeling (FEM) was employed to investigate yield stress and von Mises stress distribution of the VO-MO thin films

Recent advances in hydrothermal carbonisation:from tailored carbon materials and biochemicals to applications and bioenergy

Introduced in the literature in 1913 by Bergius, who at the time was studying biomass coalification, hydrothermal carbonisation, as many other technologies based on renewables, was forgotten during the "industrial revolution". It was rediscovered back in 2005, on the one hand, to follow the trend set by Bergius of biomass to coal conversion for decentralised energy generation, and on the other hand as a novel green method to prepare advanced carbon materials and chemicals from biomass in water, at mild temperature, for energy storage and conversion and environmental protection. In this review, we will present an overview on the latest trends in hydrothermal carbonisation including biomass to bioenergy conversion, upgrading of hydrothermal carbons to fuels over heterogeneous catalysts, advanced carbon materials and their applications in batteries, electrocatalysis and heterogeneous catalysis and finally an analysis of the chemicals in the liquid phase as well as a new family of fluorescent nanomaterials formed at the interface between the liquid and solid phases, known as hydrothermal carbon nanodots
