Nutritional status predicts outcome in patients hospitalised with exacerbation of COPD
Mathew Jayant,Veena G,Kurpad Anura,D′Souza George
Lung India , 2006,
Abstract: Nutritional status affects outcome in acute illnesses. Weight loss is associated with poor lung functions and outcome in chronic obstructive pulmonary diseases (COPD). There is not much data on the effects of nutritional status on hospital outcome in patients with acute exacerbation of COPD. This study was conducted to address this issue. Twenty five patients with COPD admitted with acute exacerbation in a tertiary care teaching hospital in Southern India were studied. Lung functions were as-sessed by spirometry. Nutritional status was assessed using anthropometric mea-sures {body mass index (BMI), mid-arm circumference (MAC), triceps skin-fold thickness (TSF) and fat free mass (FFM)}. Resting energy expenditure (REE) was measured using indirect calorimetry. Hospital outcome was determined by mortal-ity, number of days to improve subjectively and number of days to discharge. Patients with a lower BMI, MAC and TSF took a longer time to recover. REE was found to be lower in patients with weight loss unlike the Western patients. On multivariate analysis, only a lower BMI was associated with a longer time to re-covery. Thus, nutritional status is an important predictor of hospital outcome in patients with COPD.

Podostemaceae family is well known as a group of aquatic angiosperms with enigmatic characters. The present work was performed to trace ecological aspects, phenology, water analysis and phylogenetic analysis of the genus Zeylanidium, in order to establish the uniqueness of the species in the fresh water habitats S-1 (9.9559°N, 76.8339°E) and S-2 (10.0538°N, 76.8294°E). Through water analysis it is revealed that the species of plants could be used as an indicator of pollution as they are present in very sensitive area of running fresh water. The phenology of the taxa understudy paved light to the co-existence of Zeylanidium maheshwari and Zeylanidium lichenoides. The data on comparison of molecular and phylogenic tree reveal that the species are highly related genetically for a sustainable coexistence.
On the Quadratic Transportation Problem  [PDF]
Veena Adlakha, Krzysztof Kowalski
Open Journal of Optimization (OJOp) , 2013, DOI: 10.4236/ojop.2013.23012

We present a direct analytical algorithm for solving transportation problems with quadratic function cost coefficients. The algorithm uses the concept of absolute points developed by the authors in earlier works. The versatility of the proposed algorithm is evidenced by the fact that quadratic functions are often used as approximations for other functions, as in, for example, regression analysis. As compared with the earlier international methods for quadratic transportation problem (QTP) which are based on the Lagrangian relaxation approach, the proposed algorithm helps to understand the structure of the QTP better and can guide in managerial decisions. We present a numerical example to illustrate the application of the proposed method.

Abstract: Leadership skills are essential among nurses to address the challenges faced by the nursing profession. This quantitative comparative study examined five components of transformational leadership skills as outlined by Kouzes and Posner among graduating baccalaureate nursing students and practicing nurses [1]. Five leadership components were used to examine if differences existed among the groups studied. The results indicated significant differences for modeling the way, inspiring a shared vision, enabling others to act, and encouraging the heart. The study revealed that nursing students graduating from generic and accelerated programs have inferior leadership skills compared to nurses in clinical practice. The results may be useful in leadership training of nursing students through collaborative practices between practice settings and nursing schools to improve patient safety.
Design of 2,4-Dichlorophenoxyacetic Acid Imprinted Polymer with High Specificity and Selectivity  [PDF]

Abstract: A widely used herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) was imprinted on poly (4-vinylpyridine) (4-VP) using (40%) ethyleneglycol dimethacrylate (EGDMA) as crosslinking agent. The classical imprinting technology makes use of a high degree of crosslinking which does not allow the template molecules to move freely. So the binding sites, located in the central area of the three dimensional polymer matrix are hard to be accessed and the template molecules cannot be extracted totally. But here we propose a low crosslinked system with high specificity and selectivity. The imprinted and non-imprinted polymers were characterized by various spectroscopic techniques. The extent of binding was followed by batch equilibration method and compared with the respective non-imprinted polymer. Conditions for maximum specific rebinding were set by altering certain factors like template/monomer ratio, concentration of template solution, rebinding medium, mass of polymer and time of incubation. The selectivity of the imprinted polymer was investigated by comparing the binding with structural analogues of 2,4-D like, phenoxyacetic acid (POA), 4-chlorophenoxyacetic acid (4-CPOA) and 2,4,5-trichlorophenoxyacetic acid (2,4,5-T). The imprinted polymer exhibited high affinity towards the template molecule and was selectively rebound to the specific sites. The binding towards the structural analogues depends on the number of chlorine in the benzene ring.
O ato de testemunhar: violência, gênero e subjetividade
Das, Veena;
Cadernos Pagu , 2011, DOI: 10.1590/S0104-83332011000200002
Abstract: the context is the partition of india in 1949, with the creation of pakistan, as seen from the point of view of punjabi culture (the punjab was the province closer to the frontiers of the new state) and particularly through the eyes of asha, a widow 21 years old in 1941, who lived with his deceased husband's family. the transformations derived from the partition give rise to asha's following reflections. a daughter's food is never heavy on her parents. but how long will one's parents live? when two pieces of bread are experienced as heavy by one's own brother… then it is better to keep one's honor… make one's peace … and live where one was destined to live. the exegesis of this text is the analytical nucleus of the text. the author is not asking how the events of the partition were present to consciousness as past events but how they came to be incorporated into the temporal structure of relationships.
Fronteiras, violência e o trabalho do tempo: alguns temas wittgensteinianos
Das, Veena;
Revista Brasileira de Ciências Sociais , 1999, DOI: 10.1590/S0102-69091999000200003
Abstract: much recent work on violence has suggested that in contemplating violence we reach some kind of limit in our capacity to represent. large scale acts of violence such as during the partition of india in 1947 provide a "stage of horror". the story of a punjabi urban family presents the ethnographic context for pondering on how healing requires the domestication of violence. in bringing wittgenstenian themes to anthropology, the author elucidates the way in which "the work of time", rather than its image or representation, puts the limits of humanhood to the test whenever language is insufficient or is simply absent.

Abstract: OBJECTIVE: To scrutinize the protective role of hydroethanolic extract of Euphorbia neriifolia leaves (HEEN) against N-nitrosodiethylamine (DENA)-induced hepatocarcinogenesis in male Swiss albino mice. METHODS: Experimental mice were pretreated with 150 and 400 mg/kg of HEEN, or 0.5% and 1% of butylated hydroxyanisole (BHA) as a standard for 14 d prior to the administration of a single dose of 50 mg/kg of DENA. Levels of xenobiotic metabolizing enzymes such as cytochrome (Cyt) P450 and Cyt b5, activities of reduced glutathione (GSH), glutathione-S-transferase (GST), aspartate aminotransaminase (AST), alanine aminotransaminase (ALT) and alkaline phosphatase (ALP), and total protein and cholesterol content in the liver tissues were measured to determine the hepatotoxicity caused by DENA.RESULTS: The levels of Cyt P450 and Cyt b5 were significantly increased, and GST and GSH were significantly depleted after DENA treatment (P<0.01). The activities of AST, ALT and ALP, and the total protein content were also significantly dropped off (P<0.01). The total cholesterol level was markedly increased by DENA as compared with the normal group (P<0.01). However, the pre-supplementation of HEEN showed a remarkable amelioration of these abnormalities, and the levels of the antioxidant enzymes in the liver were significantly restored, which exhibited the dose-dependent protective effect against DENA-induced hepatotoxicity. CONCLUSION: HEEN exerts its chemopreventive effects by alleviating the xenbiotic enzymes and enhancing the levels of antioxidants and biochemical assays in DENA-induced carcinogenesis by reducing the formation of free radicals.
Bonus or Burden: A Daughter can't be a Son in India!
Veena Sharma
Review of Research , 2012,
Abstract: Every Indian says that times have changed now as there is no difference between a son and a daughter. It is increasingly argued that a daughter is the biggest asset to her parents in contemporary times as it is she and not their son who keeps caring, loving and maintaining them till their sunset days. Also a girl is making her parents proud by excelling in the fields of sports, education, science and technology, and literature, and so on. Even the government of India and several political parties are not behind in eulogizing daughters. It sounds optimistic and it seems we are close to kicking off the age old male chauvinism. It all indicates that a gender sensitive social structure is coming up.
