The results indicate that chlorpyrifos was the most toxic and dicofol was least toxic to adult red flour beetles. The order of toxicity of the insecticides was chlorpyrifos>lambda-cyhalothrin>malathion> cypermethrin> carbosulfan>dicofol. The results also showed a marked decrease in the effectiveness of all insecticides tested with a lowering of temperature. This difference may be related to the l owered activity of the beetles observed at low temperatures although other factors, such as a slower penetration of insecticide through the cuticle and less rapid internal transport of the insecticide to the site of action may also reduce effectiveness at lower temperatures.

Because of having particular meaning structures, these compounds make the audience interpret them in a way as desired by the authority, hence achieving the goals of persuasion. These metaphorical and metonymical compound expressions do not follow the regular morphological structures of English compounding but are motivated by metaphorical and/or metonymical realization of the word, which helps the company present their products and services in a new fashion that has not been thought of by the audience before. The paper further highlights the benefits that the companies may derive because of using such compounds instead of the traditional compound expressions in the brand names and advertisement slogans of the products and services.

That is why the term „World Englishes‟ is often used to designate these various kinds of Englishes. Like many other parts of the world, different varieties of the English are also to be found in the South Asian countries as well. As such the label “South Asian Englishes” are sometimes used as an umbrella term to designate all the variations of English used in the South Asian countries – India, Pakistan, Sri Lanka, Bangladesh, and so on. Restoring to a web-derived newspaper corpus of South Asian Englishes, namely South Asian Varieties of English (SAVE) corpus compiled on the basis of newspaper articles from online editions of twelve printed daily newspapers from six South Asian countries between the years 2002 to 2007, the present study identifies the extent to which Bangladeshi English and Indian English differ in their ...

The aims of this study were to evaluate in vitro antioxidant activities and antimicrobial property of Litseasalicifolia(ROXB.EX NEES) leaf.In total phenol content determination methanolic extract showed highest value of 102±1.414 mg/gm as Gallic Acid Equivalent (GAE). Ethyl acetate extract showed highest total flavonoid content with 285.5±6.364 mg/gm as Quarcetin Equivalent (QE) and total anti-oxidant capacity with 264.5 ±10.607 mg/gm as Ascorbic Acid Equivalent (AAE). Methanolic extract showed highest tannin content with 253.5714 ±5.051mg/gm as Tannic Acid Equivalent (TAE) and good DPPH free radical scavenging activity with IC50 of 251.227 μg/mL. In antimicrobial assay extracts showed poor activity. Further studies are needed to isolate active compounds.

The effect of chronic administration of Makardhvaja on the hematological parameters and serum iron profi le was studied in this experiment. The acute toxicity test of MD recorded no death, even at the highest dose of 80 ml/kg body weight. During the chronic toxicity test, animals were divided into two groups. The fi rst group was given MD preparation at a dose of 40 mg/kg body weight for 28 days while the second group that served as the control received water for the same period. After 28 days of chronic administration of the MD preparation to the male Sprague-Dawley rats, the following hematological changes were noted. Erythrocytic indices such as red blood count (RBC), hemoglobin, Hematocrit, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), and red cell volume distribution widt...

However, the expression of these relationships through the use of second person deixis varies significantly in the two languages as it necessarily involves both linguistic as well as social aspects. Being an Asian language, Bengali has a detailed and somewhat complex system of encoding the role relationship of the participants, their interrelationships, their social status, level of formality and politeness involved, and so on by the use of second person deixis. In contrast, English, a European language, exhibits relatively simple and straight forward ways of encoding the aforementioned issues of conversation. Based on the intuitive observation of the utterances of the two languages, the present study intends to make a comparative analysis of the use of second person deixis in Bengali and English with a view to exploring the extent to which the two languages differ linguistically and pragmatically in their encoding of social information with the use of such deictic expressions.

It exercises the ability to strongly oppose both cancer and inflammation, partially due to the fact that both conditions are highly interrelated. Endothelium hyperpermeability is considered the hallmark of severe lung inflammation, and the cardinal feature of the lethal acute respiratory distress syndrome. An emerging body of evidence suggests a strategic role of P53 towards vascular barrier integrity. The “endothelium defender” orchestrates meticulously devised responses; to counteract toxin‐induced destructions of endothelium monolayers. The present effort seeks to further our understanding on the expanding P53 universe, discussing the most recent information regarding the involvement of that molecule in the pulmonary function.

The effect of chronic administration of KTJ on the serum lipid profile was studied in this experiment. After 28 days of chronic administration of the KTJ preparation to the male Sprague-Dawley rats at a dose of 40 ml/kg the following biochemical changes were noted. There was a statistically very highly significant (p=0.001) increase in serum LDL-C level whereas a significant increase was noted in case of total cholesterol (TC) level (p=0.013). A significant (p=0.039) decrease was noticed in HDL-C level but in case of Non-HDL-C level, a highly significant (p=0.002) increase was noticed. Besides, a statistically very highly significant (p=0.001) decrease was noted in case of serum triglyceride (TG) and VLDL-C level; thus leading to a statistically highly significant increase (p=0.004) in Cardiac Risk Ratio (CR...

The present study is conducted to evaluate the effect of conventionally prepared MRS on different lipid profile parameters in experimental animals. Acute toxicity tests were conducted to determine the LD50 of the drug. To find out the effect of chronic administration of MRS on serum lipid profile it was administered chronically to the male Sprague-Dawley rats at a dose of 40 mg/kg for 28 days. The drug (MRS) did not affect triglyceride (TG), total cholesterol (TC), LDL-C, VLDL-C, HDL-C and Non HDL-C level significantly; thus leading to an insignificant change in atherogenic indices like Cardiac Risk Ratio (TC/HDL-C), Atherogenic Coefficient [(TC HDL-C)/HDL-C)], Castelli’s Risk Index-II (CRI-II) (HDL-C/LDL-C) and Atherogenic Index of Plasma (AIP) (log (TG/HDL-C)).
