The effects of music on pulse rate and blood pressure in healthy young adults

Background: Music is a combination of frequency, beat, density, tone, rhythm, repetition, loudness and lyrics. Cardiovascular autonomic function syncs with the different musical rhythms and modulates the cardiovascular system. When we are exposed to slow beat music the parasympathetic nervous system is stimulated decreasing the heart rate and while listening to fast beat music the sympathetic nervous system is stimulated and increases the heart rate. The purpose of the study was to evaluate the effects of slow and fast beat music on pulse rate and blood pressure.Methods: We conducted a cross-sectional study in 100 healthy adults of age group 18-25yrs. The subject was made to lie down in a couch and pulse rate and blood pressure is measured by LED BP apparatus. After that slow beat music (“The weightless” most relaxing song of 2011) was played through the headphone. Then the pulse rate and blood pressure were recorded immediately after the music. After a period of 5 minutes rest, again pulse rate and blood pressure were measured. Then, fast beat music (“World Wide chopper”) was played and the pulse rate and blood pressure were measured immediately after the fast music.Results: There was significant reduction in pulse rate and blood pressure after listening to slow music whereas there was significant increase in pulse rate and blood pressure after listening to fast music.Conclusions: We concluded that listening to slow beat music lowers the pulse rate and blood pressure, thereby improving the cardiac autonomic regulation

AYURVEDA MANAGEMENT OF TRAUMATIC ARTHRITIS OF KNEE (JANU VATA) WITH SPECIAL REFERENCE TO ARJUNA KSHEERA PAKA- A CLINICAL STUDY

In this clinical study 40 Traumatic arthritis patients aged 35-65 years were selected at random in OPD of TTDs S.V Ayurvedic Hospital PG Dravyaguna Dept, Tirupati. In Group I, 20 patients were treated with Terminalia arjuna powder TAP (oral intake of Arjuna powder boiled with milk). In group II, 20 patients were treated with Terminalia arjuna Ksheerapaka powder TAKP (Arjuna powder boiled with milk and filtered into semisolid and made into fine powder). The aim of the study was comparative clinical evaluation between group I and group II in the management of Traumatic arthritis.Guggulu tablets are used for joint pains. But it has Lekhana and Medohara properties and causes Vata prakopa. Thats why there is an acute need for safe herbal drug. Therefore Arjuna, a Bhagna sandhanakara drug mentioned in Vrindamadhava is taken for the study. The form of drug is Arjuna bark powder by boiled with milk (Bhagna pibeth tvak payasarjunasya).It is observed that there is no significant difference between group I and group II in the mean values of fatigue, Pain radiating to other parts and walking time but significant difference were observed in ESR before and after treatment in group I and group II. Group II showed better results in reducing restricted movement and Group I shows better results in reducing inflammation.Based on all the observed results it can be concluded that Group II has showed highly significant improvement when compared in between groups, this may be due to Jeevaniya and Sandhaniya karma of milk which causes synergetic action of Arjuna karmas. No complications were observed in the clinical study

A PHARMACOLOGICAL STUDY ON AYURVEDA MANAGEMENT ON HEALING PROCESS OF TIBIA OF RATS WITH SPECIAL REFERENCE TO ARJUNA KSHEERA PAKA

The present study was under taken to evaluate the effect of Terminalia arjuna Linn on the healing process of experimentally fractured tibia of rats. 12 Adult male wistar rats were grouped into I, II and III groups. Arjuna, a Bhagna Sandhanakara drug, mentioned in Vrindamaddhava is taken for the study.The solution of test drugs for Group I is 2mg of Terminalia arjuna powder TAP boiled with milk and Group II by 8mg of Terminalia arjuna Ksheera paka powder TAKP (Arjuna powder boiled with milk and heated till it is semisolid and after cooling it is made into fine powder) and Group III with 2mg Placebo (PG) rice powder with milk. The test solution was introduced into the oral cavity of male wister rats by rat feeding needle.On observing the radiological images, Group I and Group II shows improvement in healing process of tibia by 30th day after treatment due to Jeevaniya and Sandhaniya karma of milk which causes synergetic action of Arjuna karmas than Group III. Group II shows early healing capacity of calcification than Group 1 by 20th day compared in between group I and Group III. Based on all the observed results it can be concluded that Group 2 (Terminalia arjuna ksheerapaka powder (TAKP) is highly significant in calcification between the three groups

STUDY ON RECYCLED AGGREGATE CONCRETE WITH BLENDED GGBS

Abstract With the rapid growth in construction activities, it is important to assess the amount of construction and demolition waste being generated and analyse the practices needed to handle this waste from the point of waste management and disposal and also with regard to waste utilization in concrete from the sustainability aspects. Construction and Demolition (C&D) waste constitutes a major portion of total solid waste production in the world, and most of it is used in landfills. Research by concrete engineers has clearly suggested the possibility of appropriately treating and reusing such waste as aggregate once again in concrete, especially in applications such as bed concrete and in road beds for pavement i.e. where works are of less importance as regards to the strength. The use of such waste as recycled aggregate in concrete can be useful for both environmental and economic aspects in the construction industry. In present study, five concrete mixes were used; first mix had only natural coarse aggregate and in remaining mixes natural coarse aggregate was partial replaced by 10%, 20%, 30% and 40% recycled coarse aggregate. In all the mix cement was replaced by 10% GGBS. Here an attempt is made to assess the strength and durability characteristics of concrete made using construction and demolition waste recycled coarse aggregate

Carbohydrate specificity and salt-bridge mediated conformational change in acidic winged bean agglutinin

Structures of two crystal forms of the dimeric acidic winged bean agglutinin (WBAII) complexed with methyl-α-D-galactose have been determined at 3.0 Å and 3.3 Å resolution. The subunit structure and dimerisation of the lectin are similar to those of the basic lectin from winged bean (WBAI) and the lectin from Erythrina corallodendron (EcorL). The conformation of a loop and its orientation with respect to the rest of the molecule in WBAII are, however, different from those in all the other legume lectins of known structure. This difference appears to have been caused by the formation of two strategically placed salt bridges in the former. Modelling based on the crystal structures provides a rationale for the specificity of the lectin, which is very different from that of WBAI, for the H-antigenic determinant responsible for O blood group reactivity. It also leads to a qualitative explanation for the thermodynamic data on sugar-binding to the lectin, with special emphasis on the role of a tyrosyl residue in the variable loop in the sugar-binding region in generating the carbohydrate specificity of WBAII

Use of aqueous foams for the synthesis of gold nanoparticles of variable morphology

In this paper we describe the facile synthesis of gold nanocrystals of variable morphology using aqueous foam as a template. The aqueous foams are formed by bubbling an aqueous solution of AuCl−4 ions electrostatically complexed with the surfactant cetyltrimethylammonium bromide (CTAB). The gold ions in the stable foam are then reduced by hydrazine vapours, this process leading to the formation of gold nanoparticles of spherical, flat plate and flake-like structures. The variation in morphology of the gold nanoparticles derived from the foam is believed to arise from the complex spatial structure of reaction sites in the foam. The foam-derived gold nanoparticles were analysed by UV-vis spectroscopy, X-ray diffraction, Fourier transform infrared spectroscopy and transmission electron microscopy
