If we are in a circumstance to pick between eating fish or bacon and we are agonized over our health then we will in all likely choose fish. This is the right decision, at any rate more often. Fish contains colossal amount of proteins; in fact it doesn't contain much fat and accompanies a few advantages for our health. On the other hand, there are a wide range of types of fish available and on top of that, some of them are brought up in an unnatural way, so we should likely mull over a couple of things before we begin speaking good things about each fish. Why You Should Never Eat Tilapia?
1) Present the gel electrophoresis image of plasmid digestion experiment with the correct label. Describe the results of the experiment and list down possible problem that you observe based on the electrophoresis image. Plasmid P1-1 and P1-2 undergo single digestion. Plasmid P1-3 undergoes double digestion. Single digestion is only one restriction enzyme which has been used to digest a DNA.
DISSECTION METHOD TO APPROACH THE HUMAN CORACOID PROCESS OF THE SCAPULA 3.1 Introduction Dissection is a traditional approach to medical laboratory education(Waters, 2008). Using human cadavers one of the most widely used model in medical and clinical research for several decade .Considerable amount of literature have been published on different dissection methods of human body . (Romanes et al.,1986;Tank et al.,2008). These currant dissection manuals showed different approach to access different part of human body. However it is hard to find a standard literature which described the dissection method to access the coracoid process which can allow researchers, scientists and anatomists to approach this important anatomical structure with
However a single non-conservative mutation (Arg345Trp) in the gene EFEMP1 (for EGF-containing fibrillin-like extracellular matrix protein 1) was found to be responsible for ML.4 However, the diagnosis of ML is clinical. On fundus examination, the most prominent feature of ML is the development of small and large drusen which can develop as early as adolescence. Initially, small drusen, located in the macular area and on the nasal edge of the optic disc, show a radial distribution to the peripheral retina and, in the later stage of the disease, they progressively increase and confluent in honeycomb appearance.5 Patients with ML may occasionally present with choroidal neovascularization (CNV).6 We report the optical coherence tomography angiography (OCT-A) features of ML compared with our observations on fundus examination, autofluorescence, fluorescein angiography (FA) and indocyanine green angiography (ICGA) in XX eyes. METHODS Ten eyes of five consecutive patients affected with ML (xx females, xx male) were prospectively included. They presented to Ophthalmology Department of Intercity Hospital, Creteil, France, between Mars 2016 to May 2016 with complaints of metamorphopsia or loss of vision.
For example, using biomanipulation to improve water quality in nutrient-rich lakes. Biomanipiulation is the alteration of a food web to restore ecosystem health (Shapiro et al. 1975). The basic proposition is that secondary consumers (planktivorous fishes) are removed either through the addition of tertiary consumers (piscivorous fishes) or harvesting, which allows for the dominance of large-bodied, generalist grazers (e.g., Daphnia) to control phytoplankton. When the population of planktivorous fishes increases and there is no predation refuge (e.g., oxygenated hypolimnion) for large-bodied zooplankton, less efficient small-bodied zooplankton grazers (e.g., rotifers and herbivorous copepods) typically dominate zooplankton communities, thus allowing for the overgrowth of phytoplankton.
From the result, the general trend for the mean concentration of cadmium in the tissues revealed that; Flesh> Gills (Bones). The average lead concentrations of the same tissues of the dried Clarias gariepinus are 0.03841, 0.07521 and 0.02990 µgg-1 for the bones, gills and flesh respectively, with a grand average concentration of 0.04781µgg-1. The general trend for the average concentration of lead in the tissues showed that; Gills>Bones>Flesh. The average cadmium concentrations of the tissues of dried Oreochromis niloticus fish are 0.00161, 0.00140 and 0.00121µgg-1 for the bones, gills, and flesh respectively with a grand average cadmium concentration of 0.0014 1µgg-1 . The general trend for the average Cadmium concentration in the tissues showed that: Bone> Gills> Flesh.
However, as I was examining the object, I realized that the complexity of the object did not truly matter. What really mattered were my observation skills and ability to find something interesting even in a seemingly dull object. Being unable to take the bag clip out of the bag, I started to carefully inspect it using my tactile perception. I was touching, rubbing, scrubbing, and caressing the object. My first observations were about the shape and the size of the bag clip.
Feed is recognized as the most costly component of fish farming which constitutes 60-70% of total production costs of tilapia (Oreochromis niloticus) for small-scale, rural farmers in the Philippines (ADB 2005). The cost of commercial fish feeds are rising sharply as the market demand increases to supply growing aquaculture and the availability of fishmeal declines. About 40% of feed costs are attributable to fishmeal, which constitutes 15-20% of the feed formulation. Reductions in both the amount of feed used for grow-out of marketable fish and in the cost of formulated feeds are two approaches to containing feed costs that can effectively increase income for tilapia farmers. Much of the fishmeal used for tilapia in the Philippines is
For female fish it is also a relative measure of the ova diameter, independent of the length of the fish (Schaefer and Orange 1956). GONADOSOMATIC INDEX (GSI) The gonadosomatic index (GSI) is the ratio of ovary weight divided by fish weight or the equivalent (Davies 1956). It can be used to detect hydrated ovaries since the wet weight of hydrated ovaries is two or more times that of other maturity stages. GSI has the inherent problem that; dividing by an expression of body size usually does not compensate completely ("normalize") for the effects of fish size (Vlarning et al., 1982) and for the same reproductive state, small fish usually have a lower GSI than larger fish as this effect increases with maturation of the ovary. In other words, ovary weight increases faster with fish length than does somatic weight (Vlaming et al.
The Ekurhuleni Metropolitan Municipality alone has 1644 different species, 255 of birds’ species, 14 amphibians and 41 species of reptiles (Ekurhuleni Metropolitan Municipality, 2004). On an international scale, scientists have noticed a decline in the population of amphibians and some to the point of extinction. Amphibians are mostly affected by habitat destruction and pollution due to human activities (Primack, 1998). Amphibians are sensitive to global environmental factors like climate changes, increased ultraviolet radiation, habitat fragmentation, chemical pollution and acid rain. Chemical pollution easily penetrates in the amphibians’ epidermis and a slight change in the water pH can destroy eggs and tadpoles (Primack, 1998).
