Cymothoa Exigua in Human and Life Cycle

Jul 04, 2012 > Various
Cymothoa exigua is a tiny crustacean that sneaks up on a fish (specifically, a red snapper) and works its way in through the gills. Typical parasite behavior so far. Then it attaches itself to the base of the fish's tongue, the tongue evidently being the tastiest part of the fish (get it!?). The parasite uses its claws to dig into the tongue and drink the fish's blood--and that's just the beginning

Cymothoa Exigua in Human

It is currently believed that Cymothoa Exigua are not harmful to humans unless picked up alive, in which case they can bite.

Cymothoa Exigua in Human and Life Cycle

A tongue-eating parasite inside the mouth of a red snapper purchased from a London fishmonger recently revolted its buyer and fascinated scientists.

Previously, scientists believed fish infected with the parasite, nicknamed the "tongue louse," existed solely in the Gulf of California. The find in England suggests the parasite's range may be expanding, according to a recent press release issued by a museum in England.

But does the Cymothoa mouth-squatter leave its fishy friend tongueless? Of course not. It does what any crafty parasite would do and replaces the old tongue with its own body.

The fish is actually able to use the parasite just like a normal tongue, only it has to share all the food with its new friend. Yes, the whole foster-tongue thing seems like a pretty nice gesture on the part of ol' Cymothoa until you remember there was nothing wrong with the fish's old tongue in the first place.

Cymothoa Exigua Life cycle

Not much is known about the life cycle of Cymothoa Exigua. It exhibits sexual reproduction. It is likely that juveniles first attach to the gills of a fish and become males. As they mature, they become females, with mating likely occurring on the gills. If there is no female present, within a pair of two males, one male can turn into a female after it grows to 10mm in length. The female then makes its way to the fish's mouth where it uses its front claws to attach to the fish’s tongue.

Cymothoa Exigua in Human and Life Cycle #0Other Drugs Of Concern
Drugs discussed in the following sections have been abused for many years. Unfortunately, some that had become less popular seem to be reappearing, along with a dangerous new generation of illicit drugs. Problems with any illegal drugs include "quality control". Because there is no federal regulation of these drugs and because people involved in transportation and distribution of illegal drugs are not always concerned with purity or quality, additives to any illegal drug may include dangerous and even poisonous substances. Also, it is frequently impossible to determine the potency of the drug. A very pure form of a drug can easily be lethal for an individual who has been using a form that has been "stepped on" and was less potent.

Harper, M.D.11.From the American Society of Bariatric Physicians Research Council, 333 West Hampden Avenue, Englewood, Colorado 80110. Twenty female patients on 500 to 550 kcal diets receiving daily injections of 125 IU of human chorionic gonadotrophin (HCG) were compared with 20 female patients on 500 to 550 kcal diets receiving placebo injections. Patients in both groups were instructed to return for daily injections 6 days each week for a total of 36 injections (unless desired weight was achieved prior to this).

The most common cause of hypothyroidism is Hashimoto's thyroiditis, a chronic autoimmune destruction of the thyroid. Other causes of hypothyroidism include radioactive iodine, thyroidectomy, thioamide drugs, and iodine ingestion. Transient hypothyroidism can occur in patients with acute thyroiditis.

Cymothoa Exigua in Human and Life Cycle #7The Scope of Noise Exposure
Noise is especially prevalent in the manufacturing industries. The US Department of Labor has estimated that 19.3% of the workers in manufacturing and utilities are exposed to daily average noise level of 90 dBA an above, 34.4% are exposed to levels above 85 dBA, and 53.1% to levels above 80 dBA. These estimates should be fairly typical of the percentage of workers exposed to hazardous level of noise in other nations. The levels are likely to be somewhat higher in less developed nations, where engineering controls are not used as widely, and somewhat lower in nations with stronger noise control programmes, such as Scandinavian Country and Germany.

Are you looking for ketamine long term side effects? Ketamine is a drug used in human and veterinary medicine. Its hydrochloride salt is sold as Ketanest, Ketaset, and Ketalar. Pharmacologically, ketamine is classified as an NMDA receptor antagonist. At high, fully anesthetic level doses, ketamine has also been found to bind to opioid μ receptors type 2 in cultured human neuroblastoma cells, however without agonist activity, and to sigma receptors in rats. Also, ketamine interacts with muscarinic receptors, descending monoaminergic pain pathways and voltage-gated calcium channels. Like other drugs of this class such as tiletamine and phencyclidine (PCP), it induces a state referred to as "dissociative anesthesia" and is used as a recreational drug.
Cymothoa Exigua in Human and Life Cycle #9Emphysema Life Expectancy Stages
Emphysema occurs when the air sacs in your lungs are gradually destroyed, making you progressively more short of breath. Emphysema is one of several diseases known collectively as chronic obstructive pulmonary disease (COPD). Smoking is the leading cause of emphysema. As it worsens, emphysema turns the spherical air sacs — clustered like bunches of grapes — into large, irregular pockets with gaping holes in their inner walls. This reduces the surface area of the lungs and, in turn, the amount of oxygen that reaches your bloodstream.

W.F. Wonnink-de Jonge, C.T.A.M. Knibbeler-van Rossum, C. van der Heul, W.H. Pasteuning 181 In this case report the typical echocardiographic features of carcinoid heart disease are presented. Newer treatments such as the use of a somatostatin analogue, interferon and hepatic de-arterialisation have improved the prognosis in patients with carcinoid syndrome. Nevertheless this syndrome portends a poor prognosis in patients with cardiac involvement. Cardiac lesions are mainly located in the right side of the heart.

Fats are an essential part of every cell. They maintain the health of the skin an hair; provide insulation and protection for body organs;help transport and absorb vitamins A, D, E, and K; and provide a concentrated source of energy. However, in excess, fats are associated with several health conditions. Health studies usually report the health risks associated with dietary fat within the context of total intake of fat and saturated fat. Although a diet high in total fat is usually linked closely with a diet high in saturated fat and vice versa, a diet may be low in one type of fat and high in the other. This can then alter the risks of developing various health conditions.

Are you looking for about bill clinton diet vegan plan? When Bill Clinton announced last year that he was dropping meat and dairy in favor of a plant-based diet, it immediately threw the spotlight on veganism and its associated health benefits. "I'm trying to be one of those experimenters," said Clinton. "Since 1986, several hundred people who have tried essentially a plant-based diet, not ingesting any cholesterol from any source, has seen their bodies start to heal themselves - break up the arterial blockage, break up the calcium deposits around the heart. 82 percent of the people who have done this have had this result, so I want to see if I can be one of them."
