中文Endogenous analgesics: do humans have the ability to synthesise morphine?
ABSTRACT The alkaloid compound morphine is one of the strongest known opioid analgesic compounds and has a wide range of therapeutic applications (Yaksh 1997). Morphine was first isolated from the opium poppy Papaver somniferum, where it can be found in high levels (Shukla et al 2006). Trace amounts of morphine have been found in human […]
Role of EBV infected lymphocytes in the pathogenesis of Nasopharyngeal carcinoma
Summary We investigated the association between EBV-infected lymphocytes and the pathogenesis of Nasopharyngeal carcinoma (NPC). In situ hybridisation (ISH) and Immunohisto chemistry (IHC) were used to test the frequency and distribution of EBV-infected lymphocytes in specimens of tonsils from patients with NPC. In situ hybridisation was used for EBV encoded RNAs (EBER) and Immunohistochemical expression […]
Papillary Thyroid Cancer: Radiation induced versus Genetic Causes
Abstract Carcinoma of the Thyroid is clinically acknowledged to be a rare malignancy and contributing for less than 1 per cent of all human malignant neoplasms although it is the most common amongst cancerous growths in the human endocrine system. Apart from the conventional form of Papillary Thyroid Carcinoma (PTC), a selection of some special […]
The role of extrinsic and intrinsic regulators in haemopoiesis
Abstract Haemopoiesis requires a highly complex series of cellular events in which a small population of stem cells needs to generate continuously large populations of maturing cells. Normally, the diverse proliferative, differentiative, and maturation events required to achieve this occur with precision, which indicates that the regulatory mechanisms involved are complex. Control mechanisms tend to […]
The characteristics that such an insecticide would possess and the reasons why these are desirable
Introduction Insecticides are used throughout the world to protect against unwanted damage by insects. An insecticide causes death or irreversible damage to the targeted insect by affecting it at any stage in its life-cycle. Insecticides have great importance in the agricultural industry as they can minimise the quantity of crops lost through insect damage, thus […]
