A Conceptual Review of Shiras as Pranayatana in Charaka Samhita

Ayurveda is a life science which mainly aims at maintaining the health of an individual and at the same time treating the ailments of a diseased person. “DashaPranayatana” is a unique concept of Ayurveda mentioned in Charaka Samhita. In Sutrasthana, we find a whole chapter dedicated to the study ofDashaPranayatana and highlighted that one who knows these concepts will be known as Pranabhisara Vaidya, i.e., one who is confident and having absolute knowledge of the patient and the disease. In Charaka Samhita, we find references of ten such entities known as DashaPranayatana, which every Ayurvedic physician should be aware of, as they are seats of life or vitality. In such instance, it becomes important to understand the concept of Prana along with their seats in the context of Shareera Rachana. Shiras is one such Pranayatana mentioned in Charaka Samhita. It has been given much importance that it has been mentioned both in the context of DashaPranayatana and Marma. In this article, an attempt is made to understand and review Shiras in the context of DashaPranayatanas

Effect of Implantation Temperature on the Layer Exfoliation of H-implanted Germanium

This work describes the influence of implantation temperature on the layer exfoliation of the H-implanted Ge substrate. For the implantation at RT, post-implantation annealing showed large exfoliated regions over the sample surface. Two depths of the exfoliated regions were observed with average values of about 654 and 856 nm from the top of the H-implanted surface. In the H-implanted Ge at 300 °C, exfoliation occurred in the as-implanted state in the form of surface craters. The average depth of these craters was measured to be about 890 nm from the surface. Simulation results showed that the depth of the exfoliated regions was either located near to the damage peak or away from the H-peak depending upon the implantation temperature.

A bird’s eye view on Kesha (hair) in Charaka Samhita

Ayurveda is a Tantra which mainly aims at preserving the health of an individual and to treat the illness of a patient. The structure and function of bodily entities vary in health and disease conditions accordingly. The study of these structures acts as a yardstick to understand the health and illness of a person. One such indicator of health or disease is hair (Kesha). Kesha being one such parameter of health, description about it regarding its formation, characteristics, variation according to different body constitution (Prakruti), beneficial and harmful factors for Kesha, its maintenance, importance in clinical diagnosis and prognosis of a disease etc. is available in Ayurveda. In this article, an attempt is made to understand Kesha Sharira according to Charaka Samhita

BEP Performance Analysis of Multi-Node Self Encoded Spread Spectrum - Cooperative Diversity in Rayleigh Fading Channel

Self - encoded spread spectrum (SESS) is a novel modulation technique th at acquires its spreading sequence from the random input data stream rather than through the use of the traditional pseudo - noise code generator. It has been incorporated with multi node cooperative diversity systems as a means to combat fading in wireless channels. In this paper we analyze the cooperative SESS for Amplify and Forward CD links ( M SESS - AFCD) and SESS for Decode and forward CD links ( M SESS - DFCD) in Rayleigh fading channels. The BE P expressions are derived in closed form, and the veracity of the analysis is confirmed by numerical calculations that demonstrate excellent agreement with simulation results

CT imaging and staging of carcinoma oesophagus

Background: Over the past decades, computerized tomography (CT) technology has led to an early detection of cancers and thereby decreasing mortality rate. The objective was to demonstrate usefulness of Toshiba Activion 16 slice multi detector computerized tomography (MDCT) scan in staging of oesophageal cancer.Methods: The study was carried out in the Department of Radio diagnosis, Bapuji Hospital and Chigateri Government Hospital attached to Jagadguru Jayadeva Murugarajendra Medical College, Davangere, Karnataka, India over a period of 24 months. After taking a properly informed written consent, complete history and thorough clinical examination was done and these patients were subjected to CT scan.Results: The total numbers of patients studied in present study were 25. Out of which 10 were males and 15 were females. There were 6 patients upto the age of 54 years and 8 patients equal to or greater than 65 years of age, there were 11 patients between 55-64 years of age. Dysphagia was the most common symptom in patients and was present in all the 25 patients of present study. Other common symptoms were weight loss followed by pain in throat. Two different types of wall thickenings of the involved portion have been reported. The most common asymmetrical wall thickening was observed in maximum number of patients 18 (72%) and circumferential wall thickening was observed only in 7 number (28%) of patients out of 25 total patients showing heterogeneous/homogeneous enhancement. Lower third (40%) and middle third (40%) of the esophagus was the most common site of involvement with regards to location of oesophageal cancer followed by upper third (20%) of the esophagus. Homogeneous wall attenuation was observed in most of the cases accounting for (64%). The other type of wall attenuation noted were heterogeneous (36%).Conclusions: By performing endoscopy uncertainty lies in discrimination of muscular layer from serosal layer in most parts of esophagus. However, by employing MDCT technique separation of 2 layers of esophagus can be better judged.  Therefore, MDCT has been found to be the most valuable and preferential technique for planning operational strategy

Protective effect of Acampe praemorsa (Roxb.) Blatt. & McCann against oxidative stress

The current study was carried to make available phytochemical information and evaluation of antioxidant activity of Acampe praemorsa (Roxb.) Blatt. & McCann. The phytochemical analysis was carried out using procedures and quantified phenolic and alkaloid contents. The antioxidant activity was evaluated by in-vitro and in-vivo studies. The In-vitro antioxidant activity was carried on free radicals such as superoxide, hydroxyl DPPH, hydrogen peroxide, evaluation of reducing power. In-vivo study was carried on albino Wistar rats with different doses of extracts. The results provide that, A. praemorsa extracts have diversified phytochemicals in extracts like steroids, alkaloids, phenolics, glycosides, oils, quinones, tannins etc. The hydroalcoholic extract has more phenolic (26.80±0.51) and alkaloid (20.59±0.22) contents. The antioxidant activity results provide information that the extracts possess concentration dependent activity on tested free radicals. The hydroalcoholic extract has more protective nature against superoxide, DPPH, H2O2 free radicals and reducing power but ethyl acetate extract has more potential against hydroxyl free radical than hydroalcoholic extract. The extracts were found to be safe on toxic studies and In-vivo study results and they play significant role in controlling the oxidative enzymes such as catalase, superoxide dismutase, lipid peroxidation (malonaldehyde) in the body. Thus, it was determined that A. praemorsa have potential bioactive compounds and antioxidant activity

Radiographic imaging of metabolic bone disorders and their relative management

Background: Bone is a strong dynamic organ of the endoskeleton playing a vital role in structural integrity envisaging to keep proper shape and maintenance of the body, mineral reservoirs, blood production, coagulation and immunity. Metabolic bone diseases are a heterogeneous group of disorders that interrupt the normal homeostasis of bone formation and resorption. Bone regulates as well as acts as a host for hematopoiesis by providing niche for proliferation and differentiation of hematopoietic cell. Bone is a dynamic tissue but metabolically active as it is being constantly formed (modelling) and reformed (remodelling). Metabolic bone diseases comprise of a broad spectrum of inherited and acquired disorders characterized by abnormalities in calcium metabolism and bone cell physiology- that lead to an altered serum calcium concentration and skeletal failure.Methods: After taking a properly informed written consent and complete history, thorough clinical examination was done and these patients were subjected to radiographic imaging and biochemical analysis.Results: Serum alkaline phosphatase is a good marker in rickets and osteomalacia, ICTP in osteoporosis, pyridinoline, deoxypyridinoline in primary hyperparathyroidism, serum PICP in renal osteodystrophy.Conclusions: In cases of rickets and osteomalacia either decreased or normal values of serum calcium and serum phosphorus were obtained. But the cases pertaining to renal failure with rickets values of serum phosphorous were found to be raised. However, in all cases of rickets and osteomalacia values of serum alkaline phosphatase were also found to be raised
