Does the pattern of larynx cancer appear to cluster, or is it completely random? Based on this simple map, can you see any evidence to suggest that cases of larynx cancer cluster around the incinerator? Based on the map above in figure 1, the point pattern of the larynx cancer appear not completely random or is spatial distributed in the study area, there is visual evidence to suggest that there is some degree of larynx cancer clustering around the incinerator Fig 2a, b and c display 3D of...
The planets in our solar system is categorized in two parts, terrestrial the inner planets and Jovian the outer planets. Terrestrial planets are four planets which are closest to the sun, such as Mercury, Venus, Earth and Mars. According to their shapes and structure the terrestrial planets also known as rocky planets and they have roughly the same structure and shape, as a result these planets can be simplified to a central metallic core and an outer silicate rock mantle. In addition to these...
The world population has topped 6 billion people and is predicted to double in the next 50 years. Ensuring an adequate food supply for this booming population is going to be a major challenge in the years to come. GM foods promise to meet this need in a number of ways: Pest resistance Crop losses from insect pests can be staggering, resulting in devastating financial loss for farmers and starvation in developing countries. Farmers typically use many tons of chemical pesticides annually. Growing...
Diurnal rhythms or circadian rhythms are biological rhythms which are present in eukaryotes, bacteria, etc. that regulate biological processes in a 24-hour cycle which responds to light and darkness in an organism's environment. Circadian system ensures adaptation to daily environmental changes and functions on different levels-from gene expression to behaviour (Roenneberg and Merrow, 2005). The rhythms are generated by natural factors inside the body, however, they are also affected by...
To investigate the involvement of apoptosis in the pathogenesis of T3-induced pulmonary hypertension in the broiler chickens, expression of caspases 1, 2 and 3 genes were evaluated by semi-quantitative RT-PCR in the lung and heart ventricles. Chicks were reared for 7 weeks under standard conditions. T3 as a Thyroid hormone was added to the ration after week one of rearing. Pulmonary hypertension was induced at 49 days based on RV/TV ratio index. The relative amount of caspases (1, 2 and 3) mRNA...
1,25 dihydroxy-vitamin D3 (calcitriol or 1,25-dihydroxycholecalciferol) is known to regulate calcium and phosphorus metabolism, playing a major role in bone homeostasis. Over the past few years, research into non-skeletal effects of calcitriol has been emerging. It is involved in hormone release from endocrine glands, modulation of the immune system and affects cardiovascular, reproductive and neural functions in the body. Calcitriol also has anti- cancer effects against leukemia, colon,...
The worldwide increase the use of antibiotics as an important part of poultry production industry to treat and save from infectious bacterial diseases and as growth performance increases at subtherapeutic levels in poultry feed has caused the problem of the development of bacterial antibiotic resistance.The use for antibiotic in poultry feed which will effect growth efficiency and effects on intestinal microflora and effects on the host animal. The use of growth promoting antibiotics must...
Osteogenesis imperfecta is a rare genetic disorder related with bone fragility. People with OI are born without or insufficient collagen, a type of protein. This impairment causes bone which breaks easily, often from mild trauma or with no ostensible cause. The common symptoms include blue tint to the whites of their eyes (blue sclera), multiple bone fractures, early hearing loss, loose joints, flat feet and poor teeth. Symptoms of more severe forms of OI may include bowed legs and arms,...
The aim of this study was to formulate water-in-oil emulsion formulation containing Crocus sativus extracts versus its base without extracts as control, to determine its stability on different storage conditions and its effects on skin moisture contents and transepidermal water loss (TEWL). Material and Methods: The formulation contains 3% Crocus sativus (Saffron) concentrated extracts, and the base containing no extract, were formulated. Different stability tests were performed on sample kept...
Cyclic adenosine monophosphate (cAMP) is a secondary messenger which is integral to many biological pathways. Secondary messenger systems utilize rapidly produced, diffusible signalling molecules which then go on to activate effecter proteins (Karp, 2010). A principle protein target for cAMP is cAMP-dependant protein kinase (PKA). PKA regulates intercellular signal transduction in many biological systems through reversible phosphorylation. One such function of PKA is chemical synaptic...
