Bulk Viscous Bianchi Type V Space-Time with Generalized Chaplygin Gas and with Dynamical G and Λ  [PDF]
Shubha S. Kotambkar, Gyan Prakash Singh, Rupali R. Kelkar
International Journal of Astronomy and Astrophysics (IJAA) , 2015, DOI: 10.4236/ijaa.2015.53025
Abstract: In this paper, bulk viscous Bianchi type V cosmological model with generalized Chaplygin gas, dynamical gravitational and cosmological constants has been investigated. We are assuming the condition on metric potential \"\". To obtain deterministic model, we have considered physically plausible relations like \"\", and the generalized Chaplygin gas is described by equation of state \"\". A new set of exact solutions of Einstein’s field equations has been obtained in Eckart theory, truncated theory and full causal theory. Physical behavior of the models has been discussed.
L-proline catalyzed efficient and clean synthesis of polysubstituted benzenes in the ionic liquid [bmim]PF6
Jain Shubha,Keshwal Balwant S.,Rajguru Deepika
Journal of the Serbian Chemical Society , 2012, DOI: 10.2298/jsc111211067j
Abstract: A clean and efficient synthesis of polysubstituted benzenes has been developed via sequential vinylogous Michael addition and nucleophilic cyclization reactions of arylethylidenemalonodinitriles with arylidenemalo-nodinitriles in ionic liquid [bmim]PF6 catalyzed by L-proline.
A case of organophosphate poisoning presenting with seizure and unavailable history of parenteral suicide attempt
Pandit Vinay,Seshadri Shubha,Rao S,Samarasinghe Charmaine
Journal of Emergencies, Trauma and Shock , 2011,
Abstract: Organophosphate (OP) poisoning is common in India. Only few case reports of parenteral OP poisoning have been described. We report a case of self-injected methyl parathion poisoning, presenting after four days with seizure, altered sensorium, and respiratory distress which posed a diagnostic and therapeutic dilemma. Despite nonavailability of history of OP poisoning, he was treated based on suspicion and showed a good clinical response to treatment trial with atropine and pralidoxime, and had a successful recovery. Atypical presentations may be encountered following parenteral administration of OP poison, and even a slight suspicion of this warrants proper investigations and treatment for a favorable outcome. Persistently low plasma cholinesterase level is a useful marker for making the diagnosis.
False-positive widal in melioidosis
Valsalan Rohith,Shubha S,Mukhopadhyay C,Saravu K
Indian Journal of Medical Sciences , 2009,
Abstract: Enteric fever is endemic in this part of the world, and Widal test is one of the time-honored laboratory tests that are being used for years to diagnose the disease. On the other hand, melioidosis is a newly emerging disease from this region, which is most often misdiagnosed or underdiagnosed by clinicians. It is well accepted that false-positive Widal reactions following certain non-typhoid Salmonella infections may occur commonly. Three cases of high titers of Widal test are described, where melioidosis was the actual diagnosis in every occasion and was never suspected until diagnosed microbiologically. All the patients had shown a partial response to ceftriaxone. Blood and pus cultures grew Burkholderia pseudomallei, whereas Salmonella typhi was not isolated from blood in any patient. With appropriate antibiotics, the patients showed clinical and microbiological improvement with lowering of Widal titers. These 3 cases show that high Widal titer in any patient may mislead the diagnosis of melioidosis, and further laboratory workup should always be done to rule out melioidosis, especially in cases with nonresponsiveness to treatment.

Solvent-Free Green and Efficient One-Pot Synthesis of Dihydropyrano[3,2-c]chromene Derivatives
Shubha Jain,Deepika Rajguru,Balwant S. Keshwal,Aman D. Acharya
ISRN Organic Chemistry , 2013, DOI: 10.1155/2013/185120
Abstract: A rapid, clean, and highly efficient method for synthesis of dihydropyrano[3,2-c]chromene derivatives by one-pot, three-component condensation of aromatic aldehydes, malononitrile, and 4-hydroxycoumarin using DABCO as catalyst in solvent-free neat conditions is described. The present method has the advantages of mild reaction conditions, short reaction times, easy isolation of products, and excellent yields. 1. Introduction Multicomponent reactions (MCRs) are very important in organic synthesis due to the formation of carbon-carbon and carbon-hetero atom bonds in one pot [1–3]. Simple procedures, high bond forming efficiency, time and energy saving, and low expenditures are among the advantages of these reactions [4]. Over the past several years, chemists have been aware of the environmental implications of their chemistry. Nowadays, they are trying to develop new synthetic methods, reaction conditions, and uses of chemicals that reduce the risks to humans and the environment. Organic solvents are high on the list of hazardous chemicals because they are used in large amounts and are usually volatile liquids. Therefore, in recent years, solventless organic reactions have attracted great interest. They have many advantages such as high efficiency and selectivity, operational simplicity, low costs, mild reaction conditions, and reduced pollution [5–7]. Pyrano[3,2-c]chromenes are a class of important heterocycles with a wide range of biological properties [8] such as spasmolytic, diuretic, anticoagulant, anticancer, and antianaphylactic activity [9]. Moreover, they have been used as cognitive enhancers, for the treatment of neurodegenerative diseases, including Alzheimer’s disease, Parkinson’s disease, Huntington’s disease, amyotrophic lateral sclerosis, AIDS associated dementia, and Down’s syndrome as well as for the treatment of schizophrenia and myoclonus [10]. In addition, aminochromene derivatives exhibit a wide spectrum of biological activities including antihypertensive and anti-ischemic behavior [11–13]. Several methods have been reported for the synthesis of pyrano[3,2-c]chromene derivatives. 2-Amino-4-aryl-5-oxo-4H,5H-pyrano[3,2-c]chromene-3-carbonitriles have previously been prepared from aromatic aldehydes, malononitrile, and 4-hydroxycoumarin in the presence of organic bases like piperidine or pyridine in an organic solvent, that is, ethanol and pyridine [14]. They have also been prepared in the presence of diammonium hydrogen phosphate (DAHP), (S)-proline [15], K2CO3 under microwave irradiation [16], TBAB [17], MgO [18], H6P2W18O62 18H2O [19],
End-of-life care in the Indian context: The need for cultural sensitivity
Shubha R
Indian Journal of Palliative Care , 2007,
Abstract: End-of-life care requires dealing with challenging issues along various dimensions - physical, psychological, social and cultural. In addition to physical care, the importance of mental healthcare for patients at the end of life is now clearly recognised. However, there is much less awareness about the cultural factors that are involved in end-of-life care. Sensitivity to these factors is essential to providing high quality care and satisfaction to patients. In India, patients come from varied backgrounds. Their end-of-life needs differ according to their belief systems and values relating to life and death in general. In turn, these are influenced by the position they occupy along various dimensions, such as class, religion, caste, community, language, gender, to name a few. Moreover, cultural variations in attitudes and values have important practical implications for individuals making crucial medical decisions. It is therefore important for medical, paramedical and mental health professionals to be cognizant of these factors so as to provide effective and satisfying end-of-life care to patients. This paper discusses some of the issues in providing culture-sensitive care, using examples from the Indian context.
