Vascular Epiphytes of Far North Queensland There are several definitions of epiphytic plants, each with a subtle difference. Heywood (1993) states that an epiphyte is, "A plant that grows on the surface of another, without deriving food from its host". Raven (1992) states that an epiphyte is, "a plant that grows on another plant, but is not parasitic on it." Basically, a plant that derives its physical support from another plant (host = phorophyte (Luttge 1989)) is an epiphyte. Epiphytes
Although humans live an average of 85 years, things such as memory loss and lack of motor control can completely change a person and in a way kill her years before she dies. Vascular Dementia has the same general symptoms as "old age" only it typically occurs in younger people. Binswanger's Disease is a specific type of vascular dementia, probably the most common form, which affects people at approximately age 60. Most people diagnosed with this disease do not live past five years of its onset(1).
dementia in the population statistically doubles every 5 years: that is to say it affects only 1% of 60-64-year-olds but 30-40% of those over age 85 (Cummings, 1995). The most common causes of dementia are Alzheimer's Disease (Tueth, 1995), and vascular problems or problems related to a stroke (Yoshitake et al., 1995) . Depression, believed to cause some symptoms of dementia, may be as common in early dementia as it is by itself and may improve with prompt treatment even in people with dementia
in normal people to people with mental impairment, to being a mood enhancer (http://www.televar.com/alpha/biloba.html), to helping with such slight conditions as cough and asthma, to helping increase circulation in patients suffering from painful vascular diseases to actually having "slimming" applications (http://www.mmpinc.com/WHATS.HTM). If all these claims are true, then Gingko biloba extract sounds like a "mulit-cure"drug for the entire population. This paper will attempt to reduce the confusion
these muscles what to do. The structure of the eye begins with the fibrous tunic, vascular tunic And the retina. These are all on the wall of the eyeball, the fibrous tunic consist of the cornea and the sclera. The cornea is what covers the iris, and is the outermost layer of the eye through which light passes. The sclera or the “white” of the eye, this is what gives form to the eyeball. The vascular tunic has three parts to it; the choroids, ciliary body, and the iris. The choroids
Understanding Stroke Diagnosis and Clinical Features of Stroke Several researchers have attempted to determine the general public's knowledge about stroke risk factors and warning signs. The most commonly cited risk factors were hypertension and stress; the most frequently identified warning signs were dizziness, severe headaches, and unspecified weakness. Knowledge about warning signs may prompt early recognition of strokes and, hence increase the speed and aggressiveness with which people
classified symptoms and signs that are resulted (Clarke, D., Skrocki-Czerpak, K., Neumann-Potash, L). There are approximately six types of EDS that have been distinguished but other types exist that are very uncommon. Classical, Hypermobile, Vascular, Kyphoscoliosis, Arthrochalasia, and Dermatosparaxis. Classical and Hypermobile make up over 90% of all reported cases of EDS. With the Classical type of EDS a person would have hyperextensible (stretchy) skin with widened atrophic scars and joint
Cerebral vascular accident or a stroke is the destruction of brain substance, resulting from thrombosis, intracranial hemorrhage, or embolism, which causes vascular insufficiency. In addition, it is an area of the brain denied blood and oxygen that is required and damage is done to a part of the cells. The effect of the patient depends upon where the damage occurs and the severity of the stroke. Each year alone about 150,000 people in America die from a stroke or are seriously disabled. Stroke is
and grows up to about 15 feet in quietly flowing water up to three feet deep and the stem can grow up to six centimeters in width near the top (4). While the bottom portion of the stem can be up to six inches in width (7). The stem has scattered vascular bundles and no inner pith, like other typical monocots. The stem is composed of cellulose (54-68%) and lignin (24-32%), this helps to provide support for the stem and subsequently helps maintain the plant structure. There are also air ducts in the
Although Bryophytes and Pterophytes are both plant divisions with a common ancestor, they have little in common. While Bryophytes (mosses) are generally nonvascular and very short in height, Pterophytes (ferns) are vascular plants that usually grow much taller than mosses. While the dominant generation in mosses is the gametophyte, ferns exhibit the sporophyte generation. The details of their alternations of generation vary as well, although both have diploid and haploid stages. Alteration of generations
“Leave it alone, it will go away” is the instructions doctors specify to patients and parents of children with a vascular birthmark (“Vascular Birthmarks”). According to research, “It is estimated that approximately 10% of births have a vascular birthmark – that’s about 400,000 children per year in the United States alone” (“Vascular Birthmarks”). The two main types of vascular birthmarks are Hemangiomas, a non-cancerous tumor of skin composed of abnormal lymph vessels, and Malformations, an inborn

Optimizing each of these factors can provide additional benefits of decreasing the risk for Peripheral Vascular Disease. High Blood Pressure Regular physical activity can reduce blood pressure in those with high blood pressure levels. Physical activity reduces body fat, which is associated with high blood pressure. Noninsulin-Dependent Diabetes By reducing
Epilepsy Epilepsy is a condition characterized by recurrent seizures which are unprovoked by any immediately identifiable cause (Hopkins & Shorvon, 1995). It is also known as a seizure disorder. A wide range of links and risk factors are associated with the condition, but most of the time the cause is unknown. Epilepsy is one of the most common neurological disorders, affecting approximately two and half million people in the US and about 50 million worldwide. Though seizures can occur at any

Of the chemical neurotransmitter substances, serotonin is perhaps the most implicated in the treatment of various disorders, including anxiety, depression, obsessive-compulsive disorder, schizophrenia, stroke, obesity, pain, hypertension, vascular disorders, migraine, and nausea. A major factor in the understanding of the role of 5-HT in these disorders is the recent rapid advance made i... ... middle of paper ... ... needs to be discussed further.

Yet you just got stuck in the minors, and the only way you could get to the big’s was to take a pill that made you super-strong and super-fast. It would make sense to just take it. But what if that pill shrunk your testicles, hurt your heart and vascular system, and made your heart work 3 times harder than it is suppose to? An athlete would be pressured to take these pills, yet it would be smarter to say no. Why would athletes, of all people-risk harming their bodies? If I became a major league baseball
is a neurological disorder characterized by the inability to recognize familiar objects (Farah, 1990). Object recognition is the ability to place an object in a category of meaning. Most cases of visual agnosia are brought about through cerebral vascular accidents or traumatic brain injury typically inhibiting sufficient amounts of oxygen from reaching vital body tissues (Zoltan, 1996). There are a vast array of impaired abilities and deficits associated with individuals diagnosed with visual agnosia

major groups of plants are the bryophytes and the vascular plants; the latter group consists of nine divisions that have living members. Bryophytes and ferns require free water so that sperm can swim between the male and female sex organs; most other plants do not. Vascular plants have elaborate water- and food conducting strands of cells, cuticles, and stomata; many of these plants are much larger that any bryophyte. Seeds evolved between the vascular plants and provided a means to protect young individuals
The functions of rhizoids are root-like structures that absorb water and transport materials to the plants. The position of the archegonium and antheridium relates to their reproductive function by having the archegonium located under the eggs so that when the antheridium sperm is dispersed, it can reach the egg better. Antheridium is upright so that the sperm can be dispersed on top and reach the archegonium egg to fertilize the plant. They are also located near each other so that when there is
