Lingual lipase is a water soluble enzyme that primarily catalyses the breakdown of fats and converts them to free fatty acids, monoglycerides and diglycerides. They play an important role in food digestion. Lingual lipase which was discovered in 1976 is a member of a family of digestive enzymes called triacylglycerol lipases, that use the catalytic triad of aspartate, and serine to hydrolyze medium- and long-chain triglycerides into partial glycerides and free fatty acids.
ABSTRACT The Gastro intestinal system is vital for overall secretions, digestion, absorption, and movement within the tracts. Secretions involve release of fluids, chemicals and catalytic substances that facilitates digestion and related gastrointestinal tract (GIT) activities. Digestion involves hydrolysis of condensed products of carbohydrates, proteins and fats. Absorption involves movement of molecules across the GIT into the circulatory system. Carbohydrates are hydrolysed to monosacc...
ABSTRACT Orexins are recently discovered neuropeptides synthesized by neurons located in the posteriolateral hypothalamus. There are about 10,000 to 20,000 of these neurons in the hypothalamus and their axons extend throughout the brain and spinal cord where their receptors are located. The word Orexin is a Greek word reflecting orexigenic (appetite stimulating) activity of hormone. There are two types of Orexin – Orexin-A and Orexin-B – and these are essentially the same as hypocretin...
AbstractThe endocrine system is a system of glands, each of which secretes a type of hormone directly into the bloodstream to regulate the body. Many of the body's hormones influence growth, such as growth hormone, thyroxine, insulin, and corticosteroids (all of which influence growth rate), leptin (which alters body composition), and parathyroid hormone, 1,25-dihydroxy-vitamin D, and calcitonin (all of which affect skeletal mineralization). However, the key hormone in growth is GH which is...
Digestion is the breakdown of complex food substances into simple and absorbable form by the aid of enzymes using a process known as hydrolysis. Carbohydrate basically are divided into three: Polysaccharides (example Starch), Disaccharides (Sucrose and Lactose), and monosaccharides (Fructose, Galatose and Glucose). Almost all the carbohydrates of the diet are either large polysaccharides or disaccharides, which are combinations of monosaccharides bound to one another by condensation (Guyton...
Brown-Séquard syndrome, also known as Brown-Séquard's hemiplegia and Brown-Séquard's paralysis, is a loss of sensation and motor function (paralysis and anesthesia) that is caused by the lateral hemisection (cutting) of the spinal cord. This may be seen most often in the cervical (neck) or thoracic spine. Other synonyms are hemiparaplegic syndrome, hemiplegia ethemiparaplegiaspinalis, and spinal hemiparaplegia. Brown-Séquard syndrome is characterized by loss of motor function (i.e...
Cell to cell signaling refers to the transfer of information from one cell to another. This is also called cell signaling or intercellular communication. The ability of cells to perceive and correctly respond to their microenvironment is the basis of development, tissue repair, and immunity as well as normal tissue homeostasis. Errors in cellular information processing are responsible for diseases such as cancer, autoimmunity, and diabetes. The cells of the body communicate with each other ...
Blood is a specialized connective tissue in fluid form that flows through the entire body of a person or animal. Blood flow is the continuous circulation of blood through the cardiovascular system to body tissues and organs. An adequate amount of blood supply is necessary for the proper functioning of all body organs. This is vital as the blood carries and supplies body tissues and organs with its daily metabolic requirements while it also gets rid of any waste arising from tissue metabolis...
ABSTACT The effect of 0.25mg/kg weight of diesel on the liver function of male wistar rats was investigated. Ten male wistar rats were used and were grouped into two; experimental and control. The experimental group was fed with rat chawl and a mixture of diesel with water ad-libitum while the control was fed with rat chawl and tap water for about five weeks. Data collected was analyzed using student’s t-Test and a p-value of < 0.05 was accepted as significant. The result shows diesel ...
ABSTRACTIsolated organs or tissues are body parts, organs, systems or tissues separated from the body and placed in an artificial nutrient medium similar to bloodplasma in salt composition and osmotic pressure and temporarily retaining their principal functional properties. They are used to study certain aspects of organ activity, elucidate the action of medicinal substances and poisons, provides researchers with convenient biological models that are independent of the systemic influence...
ABSTRACTInsulin treatment is the use of insulin and similar proteins to treat diseases including diabetes and its acutecomplications as an effective way of lowering blood glucose level in individuals with impaired Islet beta cellfunctions. The Islets (Island) of Langerhans are small clusters of cells scattered within the pancreas of mostvertebrates to bring about the secretion of the polypeptide hormone, Insulin, which is responsible for theevacuation of excess glucose in the blood stream whi...
Anxiety disorders as the name implies are disorders associated with excessive feelings of anxiousness and nervousness. They are among the most prevalent categories of mental illnesses (Kessler et al., 2005; Shearer, 2007) which are characterized by excessive and unrealistic worry about everyday tasks or events, or may be specific to certain objects or rituals. Anxiety in itself according to Nuss (2015) is a frequent negative emotional state characterized by feelings of worry and apprehension,...

ABSTRACTThis study investigated influence of gender and self-esteem on depression among diabetic patients. One hundred and thirty (130) diabetic patients (77 with low self-esteem and 53 with high self-esteem) were used. Males and females were 65 each. Self-rating depression scale Zung (1965) and index of self-esteem Hudson (1982) were used. A 2x2 factorial design was adopted while two way ANOVA statistics was used for data analysis. Gender was found to significantly influence depression among...
