Management of Vipadika (Palmoplantar Psoriasis) with Ayurveda - A Case Study

Vipadika is explained under the context of Kshudra Kushta. The symptoms are correlated with palmoplantar psoriasis. Vatakaphadosha predominantly involved in this disease. It is characterized by Panipadasphutana and Teevravedana. Here is a case of 8 year old child with history of cracks in foot with pealing and discoloration, pain, itching and occasional bleeding since 3 years. Patient was treated with Vatakaphahara treatment with Sneha and Sweda and Veshtana Chikitsa for 1 week and Shamana Oushadis for 15 days. Patient had good relief in symptoms

Antibodies directed to the phospho-tau peptide (residues 111-137) dissociate tau oligomers and reduce the spatial memory deficits in non-transgenic tauopathy model rats

355-359In dementia, Alzheimer’s disease (AD) is the most common type, characterized by the deposits of neurofibrillary tangles and senile plaques with concomitant deterioration in spatial memory and other cognitive functions. Till date, although no cure is available for AD, a few treatment options offer help in reducing the symptoms. In the present study, the sequence 111-137 in the distal N-terminal charge transition region of tau, harbouring the pathologically relevant phospho-serine (pSer 113) and phospho-threonine (pThr 123) (111TPpSLEDEAAGHVpTQARMVSKSKD GTGS137) was selected as a potential immunotherapeutic peptide. Polyclonal anti-peptide antibodies raised in rabbits effectively dissociated the oligomers/aggregates of recombinant human tau in vitro. Administration of affinity purified anti-peptide antibodies to the okadaic acid induced tauopathy model rats resulted in a significant progress in spatial memory functions in Barnes maze task with concomitant reduction in p-tau levels in the hippocampal homogenates. Thus, targeting the phospho-residue sequence 111-137 in tau may be therapeutically relevant for AD and other related tauopathies. These antibodies may also have a clinical value in terms of immunosassay development for quantitation of pathology associated pSer113 and pThr 123 in AD samples

Urdhwagata Amlapitta – A Case Study

Amlapitta, a gastrointestinal tract (GIT) disorder, has acquired majority of the causative factors like improper diet and habits, stress, spicy irritant food, oily foods, bakery products, etc., A single clinical trial with pre test, follow up and post test assessment was done with drug, Triphala Churna advised twice daily after food for a month and also lifestyle including Ahara, Vihara and Achara was advised. By the present study it can be concluded that Triphala Churna and lifestyle modification helps in controlling and is a safe and effective treatment for Urdhwagata Amlapitta

Publication productivity of Prof. P.S. Narayanan: A Scientometric Portrait

Understanding of Unmada in Ayurveda and Rational Application of Herbal Drugs - A Review

Unmada depicts a range of different psychological conditions described under a single heading. The various components affected can be broadly classified under Mana (psyche), Buddhi (Intellect) and physical components. And depending on these different entities involved in the presentation of Unmada, the drugs are to be selected and treatment should be planned. With this idea, the classical texts and Nighantus were searched and the mode of action of drugs was analysed depending on their properties. Their possible role in different types of Unmada depending on Dosha predominance was assessed. The possible clinical application of these drugs in different Psychiatric conditions was supported with evidences from recent researches. It was found that among various drugs used in Unmada, some act by their nootropic property and the others by their high anti-oxidant activity. Some drugs help in repairing the damaged neurons. Some act directly on the neuro-humoral mechanisms (Glutaminergic, Dopaminergic). Some are found to have a potent anxiolytic effect. Some drugs have a depressant effect on CNS whereas others act as stimulants. Thus with this analysis, selection of drugs becomes easier in a given condition of Psychosis

Sensor/Control Surface Fault Detection and Reconfiguration using Fuzzy Logic

In the aircraft flight control systems, a quick detection of the faults, that occur in actuators, control surfaces or sensors, is necessary. In this paper, sensor fault detection and reconfiguration is performed using Kalman filter by estimating the states of the plant and comparing them with respective measured values from the sensors. Sensor fault detection and reconfiguration is carried out using non-model-based fuzzy logic technique. Control surface fault detection and reconfiguration is carried out by identifying the elements of control distribution matrix using extended Kalman filter and fuzzy logic. In estimating the factor of effectiveness of the control surface using fuzzy logic, different implication methods such as Mamadani's minimum, Larsen's product, bounded product and drastic product have been used and a comparison is made.Defence Science Journal, 2010, 60(1), pp.76-86, DOI:http://dx.doi.org/10.14429/dsj.60.11
