Helicobacter pylori(H. pylori) infection is highly prevalent in human,affecting nearly half of the world's population; however,infection remains asymptomatic in majority of population. During its co-existence with humans,H. pylori has evolved various strategies to maintain a mild gastritis and limit the immune response of host. On the other side,presence of *** is also associated with increased risk for the development of various gastric pathologies including gastric cancer(GC). A complex combination of host genetics,environmental agents,and bacterial virulence factors are considered to determine the susceptibility as well as the severity of outcome in a subset of individuals. GC is one of the most common cancers and considered as the third most common cause of cancer related death worldwide. Many studies had proved H. pylori as an important risk factor in the development of non-cardia GC. Although both H. pylori infection and GC are showing decreasing trends in the developed world,they still remain a major threat to human population in the developing countries. The current review attempts to highlight recent progress in the field of research on H. pylori induced GC and aims to provide brief insight into H. pylori pathogenesis,the role of major virulence factors of H. pylori that modulates the host environment and transform the normal gastric epithelium to neoplastic one. This review also emphasizes on the mechanistic understanding of how colonization and various virulence attributes of H. pylori as well as the host innate and adaptive immune responses modulate the diverse signaling pathways that leads to different disease outcomes including GC.

Various studies have confirmed that high thermal resistance in roof & wall can reduce the heat transfer load of the buildings. In this study, experimental investigation of the effects of some sustainable features (such as green roof, reflective coated roof & Fly ash brick (FAB) etc.) on the building has been conducted in the Indian context. For the purpose, two scaled building models i.e. Model I (conventional design) & Model II (green design) have been examined with different design configurations. The sensible heat transfer (SHT) load of the building is reduced by 21% - 29% through the use of FAB with cavity wall in place of Fired clay brick (FCB) wall. The load reduction increases to 26% - 44% by using FAB cavity wall with reflective coating on the roof. This reduction further increases to 64% - 68% with FAB cavity wall along with green roof. In this final scenario, the monthly electrical energy saving for air-conditioning is approximately 5.1 kWhe/m2 per unit envelope area, with associated reduction in GHG emissions up to 6.36 kg CO2eq/m2 per unit envelope area, assuming continuous operation of HVAC systems.

A perfect solution to the present natural convective flow problem of a vertical transfinite plate owing to the impulsive motion in the ubiety of first ordered chemical reaction, radiation absorption, radiation, Newtonian heating and species concentration in its plane is evolved by applying the method of Laplace transforms in closed form at the plate. Exact results for velocity, temperature, concentration fields are prevailed and expressions for heat and mass transfer rates are also found. The effects are analyzed for the respective invariables for both ammonia and water vapor.

A case of 16 yrs male patient with parosteal lipoma affecting the lower metaphyseal end of the left femur is presented. Clinical suspicion, plain radiographs, CT (Plain and 3 D) as well as MRI suggested a diagnosis of parosteal lipoma. Lipomas may be defined as benign lesions of mature adipose tissue without evidence of cellular atypia [1]. Lipomas are the most common soft tissue lesions and surprisingly are among the rarest bone neoplasias. The most frequent complaints are a tumoral convexity presenting as a visible or palpable mass or a mild-intensity, dull pain. The parosteal type is a rare tumor accounting for 0.3% of all lipomas [2] and is usually asymptomatic. It is seen commonly affecting adults aged over 40 [3]. The present article describes a rare case of parosteal lipoma located in the femur, with extensive hyperostosis visible on plain xray and confirmed by imaging studies (CT and MRI). Unlike the parosteal lipomas reported in adults over 40 yrs in this case it presented in a much younger age group.
