Different approaches toward the enhancement of drug solubility and/or dissolution rate
No full textNontraditional methods such as supercritical antisolvent processing and ultrasonic processor rely on physical alterations to enhance drug solubility and dissolution rate. They are advantageous because of their application to a wide variety of drugs and relatively short processing time. Our works show reduced particle size and complexation with these techniques results in the modification of dissolution rate and or solubility. Crystalline form of a drug is preferable because most drugs occur in this form and tend to be stable at this condition. Towards this effort new nanosized crystalline coordination drug polymers are synthesized to enhance drug solubility or dissolution rate. γ-Indomethacin (IMC) is successfully processed with the supercritical antisolvent (SAS) technique. Pure, acicular (needle-like) particles of the α-polymorph are consistently obtained with SAS as the solvent, concentration, temperature and pressures are varied. Controlled changes in process parameters yield significant changes in particle size. Enhanced dissolution profiles are observed with IMC processed with SAS as opposed to the unprocessed IMC. The reduced particle size, as well as the α-polymorphic form of IMC, contributes to the enhanced dissolution rate. Hydroxypropyl-β- cyclodextrin complexation of γ-Indomethacin (IMC) was processed with the supercritical antisolvent (SAS) technique as well. SAS processing resulted in the highest initial dissolution rate of IMC complexed particles compared to both spray drying and the physical mixture. This initial increase in dissolution rate is attributed to the micronization of particles. The addition of the water soluble polymer polyvinylpyrrolidone (PVP) to the IMC complex enhanced the dissolution rate further. Finally, the synthesis of new nanosized crystalline coordination drug polymers is explored. These crystalline coordination drug polymers are composed of the drug molecules coordinated to zinc metal ion as a ligand. The dissolution is controlled mainly by the release of the bridging ligands. These new nanocrystalline CDPs serve as potential for enhanced dissolution.Ph. D.Includes bibliographical referencesIncludes vitaby Princy Ann Abraha
A study on the symptamatology and diagnostic methodology of Vatha Kannagam
No full textThe author concludes the study on Vathakannagam with fruitful results validating the symptomatology and siddha diagnostic methodology. Study on Naadi threw up a narrow identifiable (Vathapithan) for Vathakannagam. So the presence of vathapitha naadi in Vathakannagam patients should be taken as a sign of altered vatha humour followed by altered pitham humour which might lead on this disease. If normal patients found with vathapitham naadi other than pitha kaalam, they should be taken as a pathological state and preventive measures should be adapted. Nearly more than 60% of the cases were observed results a clinician can diagnose this clinical entity as Vathakannagam with confidence.
Sedentary life style, mental stress and increased exposure to air are said to be an important factor initiating or aggravating the Vathakannagam, in this study also most of the patients had initial tripping, tottering and staggering in dizziness while climbing up or getting down or trying to step high off the ground, general weakness in the whole body due to relaxing of the muscles, and spreading wide the limbes as it were a wings of the bird. It can be concluded that with the genesis of Vathakannagam and subsequently the Vathakannagam could be the path of development of the disease. So along with medicines for improving the functional disabilities yogam and physical activities or exercises, they improve the weakness in the whole body.
Vaatham humour which is the root cause of this disease, it was found to be elevated which confirms the literary standpoint said by Sage Yugi. Therefore steps should be taken to keep it under check. Most of the patients had Vathapitham thega amaippu, it is an important factor precipitating this disease.
Study on Neerkuri in this study can be taken as one of the significant diagnostic tool for diagnosing this disease. With study on udal thathukkal, it was found that all cases (100%) had affected oon, kozhuppu, enbu, moolai, and sukkilam thathu, and 30% had affected with Senneer. So the medicines should be prescribed for strengthen these udal thathukkal.
Neerkuri and Neikkuri is one of the effective diagnostic and prognostic tool used in this study. Segregation of humours depending on clearance / pale yellow and yellow colour of urine in neerkuri and vathapitham neikkuri in structural changes. By corroborating the modern knowledge to this age-old method can be enhanced and new horizons can be explored. Neikkuri (Oil spreading sign) is based on the consistency, thickness, density of urine and by seeing the shape of spread oil drop on the urine surface. These changes in the properties of the urine as compared to normal occur due to release of various excretory substances in the urine in different disease conditions which can be assessed by the patterns formed by the oil drop during this neikkuri and thereby the diagnosis and prognosis can be assessed. According to our system, due to alternation of the bodys normal physiological functions during diseases and production of Vatham,Pitham, Kapham, the chemical composition of urine also changes which ultimately changes the pattern of oil drop spreading.
CONCLUSION:
The patients with symptoms of Vathakannagam mentioned by Sage Yugi confirmed to majority of symptoms mentioned in the modern literature of Cerebellar ataxia. Thus the study validated the symptomatology elucidated by Sage Yugi and matched it with severity of the disease.
From this study, it is evident that, with Naadi, Manikadai nool, Neerkuri, Neikuri and udal thathukkal examination, this disease can be diagnosed easily and confidently. The author concludes that these diagnostic parameters can be successfully implemented by the physician at the clinical level in the diagnosis of Vathakannagam
A Comprehensive Review: COVID-19 And Post-Covid Versus Thromboembolism
No full textIn spite of the fact that COVID-19 was previously predominantly believed to be a respiratory ailment, rapidly increasing data point to a significant prevalence of venous thromboembolic consequences in the disease. This review article\u27s main goal was to determine if there was a requirement to raise knowledge of PE (Pulmonary Embolism) in the aftermath of the COVID-19 outbreak given the still-weak epidemiologic data. The gathered studies were subjected to a critical evaluation and literature search. A digital search of Science Direct, Google Scholar, PubMed, and Scopus until June 2022. COVID-19’s lasting effects on health are yet mostly unknown. The pathophysiology of pulmonary embolism is highlighted in this review, along with the significance of being aware of the possible ways that enhanced the risk of VTE (Venous Thromboembolism) in patients suffering from post- COVID-19, including those who have a moderate or asymptomatic illness. To define suitable clinical care recommendations for the avoidance of thromboembolic consequences in the critically sick and post-COVID-19 phase, further study is necessary.

No full textOn 28th January 2023 at 02:30 PM first author (PC) recorded and photographed the completely black in colour cat species during the jungle safari in the Great Rann of Kutch, Gujarat, India. Based on the photographic evidence we identified the species as Jungle cat (Felis chaus), which was affected by melanism. In this note, we highlighted the importance of color aberration on wild animals in their natural habitats. This is necessary for a better understanding of this phenomenon and its insights into the ecological and physiological implications of this condition considerably affecting animal survival
Rail Internet of Things: An Architectural Platform and Assured Requirements Model
No full textGiven the plethora of individual preferences and requirements of public transport passengers for travel, seating, catering, etc., it becomes very challenging to tailor generic services to individuals’ requirements using the existing service platforms. As tens of thousands of sensors have been already deployed along roadsides and rail tracks, and on buses and trains in many countries, it is expected that the introduction of IP networking will revolutionise the functionality of public transport in general and rail services in particular. In this paper, we propose a new communication paradigm to improve rail services and address the requirement of rail service users: the Rail Internet of Things (RIoT). To the best of our knowledge, it is the first work to define the RIoT and design an architectural platform that includes its components and the data communication channels. Moreover, we develop an assured requirements model using the situation calculus modelling to represent the fundamental requirements for adjustable, decentralised feedback control mechanisms necessary for the RIoT-ready software systems. The developed formal model is applied to demonstrate the design of passenger assistance software that interacts with the RIoT ecosystem and provides passengers with real-time information that is tailored to their requirements with runtime adaptability
