Bench-to-bedside review: Distal airways in acute respiratory distress syndrome
Manu Jain, J Iasha Sznajder
Critical Care , 2007, DOI: 10.1186/cc5159
Abstract: The lung can be partitioned into the airways and parenchyma. The airways form the conduits between the outside world and the primary gas exchanging unit, the alveolus. There are three major groups of intrapulmonary airways; cartilaginous bronchi, membranous bronchioles and gas exchange ducts. Distal airways, defined in this review as airways less than 2 mm in diameter, are comprised of both membranous bronchioles and gas exchange ducts [1]. Because evaluating distal airways is challenging, relatively little has been published on their role in respiratory failure of various causes. In the present review we will highlight the experimental and clinical findings for the role of distal airways in acute respiratory distress syndrome (ARDS) as well as evaluating their function in mechanically ventilated patients.The trachea divides into two primary bronchi that enter the lung at each hilum. After entering the lungs the primary bronchi branch downward and outward repeatedly, giving rise to smaller bronchi, which results in a dramatic increase in the number of airways and a progressive decrease in the diameter of each airway (Figure 1). Eventually, bronchi enter a pulmonary lobule and are then termed a bronchiole. Bronchioles are intralobular airways with diameters less than 5 mm that branch into five to seven terminal bronchioles. Each terminal bronchiole subdivides into two or more respiratory bronchioles that transition into alveolar ducts. Alveolar ducts open into atria that communicate with alveolar sacs, which terminate into alveoli. Saclike structures measuring about 200 μm in diameter, alveoli can evaginate from respiratory bronchioles, alveolar ducts and alveolar sacs. For the purposes of this review, distal airways will refer to airways less than 2 mm in diameter that consist of small membranous, terminal and respiratory bronchioles as well as alveolar ducts. The small membranous and terminal bronchioles carry out conductive functions, whereas respiratory bronchiol

Abstract: A crucial step in the development of muscle cells in all metazoan animals is the assembly and anchorage of the sarcomere, the essential repeat unit responsible for muscle contraction. In Caenorhabditis elegans, many of the critical proteins involved in this process have been uncovered through mutational screens focusing on uncoordinated movement and embryonic arrest phenotypes. We propose that additional sarcomeric proteins exist for which there is a less severe, or entirely different, mutant phenotype produced in their absence. We have used Serial Analysis of Gene Expression (SAGE) to generate a comprehensive profile of late embryonic muscle gene expression. We generated two replicate long SAGE libraries for sorted embryonic muscle cells, identifying 7,974 protein-coding genes. A refined list of 3,577 genes expressed in muscle cells was compiled from the overlap between our SAGE data and available microarray data. Using the genes in our refined list, we have performed two separate RNA interference (RNAi) screens to identify novel genes that play a role in sarcomere assembly and/or maintenance in either embryonic or adult muscle. To identify muscle defects in embryos, we screened specifically for the Pat embryonic arrest phenotype. To visualize muscle defects in adult animals, we fed dsRNA to worms producing a GFP-tagged myosin protein, thus allowing us to analyze their myofilament organization under gene knockdown conditions using fluorescence microscopy. By eliminating or severely reducing the expression of 3,300 genes using RNAi, we identified 122 genes necessary for proper myofilament organization, 108 of which are genes without a previously characterized role in muscle. Many of the genes affecting sarcomere integrity have human homologs for which little or nothing is known.

Abstract: In the nation’s economic growth, the significance of technology and the growth of a viable advantage for companies cannot be over emphasized. It is obvious that in many developing and developed countries the higher educational institutions have been a main source of science and technology advancement. Therefore, the effective transfer of technology from higher educational institutions to companies or industry has been a vital concern on the behalf of governments and an appealing research topic on part of academics for more than two decades. This paper provides certain practical guidelines for government and companies concerned. The overall model presented in this paper address the main problem of the factors that affects higher education institutions performance in term of transfer and development of technology in China. A transfer and development of technology case study at Tsinghua University proposes that fruitful practice of transfer and development of technology already exist.

Open Journal of Social Sciences (JSS) , 2018, DOI: 10.4236/jss.2018.612013
Abstract: University Science Parks in China were the outcome of commercialization of the Research and Development grants and the proximity of the Higher Education Institutions and enterprise’s association. The Chinese government considers University Science Parks as a key ingredient in the nation’s inventive system. The continuous success and achievements of the TusPark are no exception. Along with the government backing, TusPark exploits different efficient tactics to encourage Science and Technology marketization, inventive actions, and nation’s economic development. However, TusPark also encounters various external and internal institutions; it has fetched its benefits into complete production and developed to the utmost prominent China’s University Science Park. The evolution flight of TusPark is exceptional; however, its skills can aid towards the interpretation of the science parks within the progressive and further developing nations in the proliferation’s framework. The functional development and progress and, various strengths and challenges of TusPark were reviewed in this paper.

Point of sale tobacco advertisements in India
Chaudhry S,Chaudhry S,Chaudhry K
Indian Journal of Cancer , 2007,
Abstract: Background : The effect of any legislation depends on its implementation. Limited studies indicate that tobacco companies may tend to use such provision for surrogate advertising. The point of sale advertisement provision has been placed in the Indian Tobacco Control legislation. The study was undertaken to assess the Indian scenario in this regard. Objective : To assess if there are any violations related to provision of point of tobacco sale advertisements under India′s comprehensive tobacco Control legislation in different parts of India. Materials and Methods : Boards over various shops showing advertisements of tobacco products were observed in the cities of Delhi, Mumbai, Kolkata, Trivandrum and Jaipur, between September 2005 and March 2006. Results : The point of sale advertisements mushroomed after the implementation of 2004 tobacco Control legislation. Tobacco advertisement boards fully satisfying the point of sale provision were practically non-existent. The most common violation of point of sale advertisements was the larger size of the board but with tobacco advertisement equal to the size indicated in the legislation and remaining area often showing a picture. Invariably two boards were placed together to provide the impression of a large single repetitive advertisement. More than two boards was not common. Tobacco advertisement boards were also observed on closed shops/ warehouses, shops not selling tobacco products and on several adjacent shops. Conclusion : The purpose of the point of sale advertisements seem to be surrogate advertisement of tobacco products, mainly cigarettes.

Golden Research Thoughts , 2013, DOI: 10.9780/22315063
Abstract: The term Social Worker is used very casually for any person doing any spiritual, political or welfare work for the benefit of society. The role and function of such social workers vary with their personal interest and motives. However, in social work literature we have considerable body of literature which defines the role and responsibilities of a social worker in various contexts. In India the role of a social worker is understood in lines of role of social reformers or political thinkers. The complex nature of Indian society further makes the role of social worker very challenging. The present paper is an attempt to explore the role of social workers in non-government organization. The objective of present paper is to understand the difficulties faced by social workers in delivery of their service and also to identify the areas where the role of professional social workers could be strengthened.
BENEFIT-COST RATIO OF OPEN SPACE PRESERVATION FOR THE CAUSE OF ENVIRONMENT & TOURISM DEVELOPMENT IN AN INDIAN CITY
Pradeep Chaudhry
Tourismos : an International Multidisciplinary Journal of Tourism , 2012,
Abstract: Governments in developing countries, generally, convert open spaces meant for greenery or some recreation project, to concrete forest for revenue maximization. In this way, long term gains of preserving such spaces for the benefits of residents or tourists are ignored. Nek Chand’s Rock Garden in the Chandigarh city of India is an environmental education spot visited by millions of tourists each year. City administration considered this project as violation of city’s master plan in the beginning but later on agreed to maintain this monument. Annual tourism value of this spot is very handsome but amount spent by city administration on its maintenance and expansion is still not adequate. Need for maintaining this important site by way of high benefit cost ratio (B/C ratio) has been emphasized in the article.
