Blindness Common from Uveitis - Eye Disorders including cataracts, Lasik eye surgery, blindness, glaucoma and eye allergy
Blindness Common from Uveitis
Background: Uveitis is inflammation of the part of the eye called the uvea. Loss of vision with this disease usually is due to low grade but chronic inflammation. There is typically very slow damage to the macula, which is responsible for fine central vision.

Antidepressants as a Treatment for Hot Flashes in Women
Introduction
Hot flashes are one of the most bothersome problems for many menopausal women and breast cancer survivors. They are described as transient occurrences of flushing and extreme warmth, often in conjunction with palpitations and anxiousness, followed by profuse sweating and occasionally chills and shaking.[1,2] The frequency, duration, and intensity of hot flashes vary. In the majority of women, they are prevalent during the first two years of menopause.[2] While the exact pathogenesis of hot flashes has not been fully established, hot flashes are vasomotor symptoms thought to originate within the anterior hypothalamus and are associated with a lack of thermoregulation due to estrogen withdrawal.[3] A relationship also seems to exist between the onset of hot flashes and the release of luteinizing hormone, though hot flashes have been reported in patients with diminished or absent levels of this hormone. Other theories suggest that, in addition to estrogen withdrawal, other centrally acting mediators (i.e., 3-methoxy-4-hydroxyphenylglycol [a metabolite of norepinephrine], dopamine, and serotonin) may be responsible for or associated with the development of hot flashes.[5,6]

RedNova News: Improved Laser Surgery Good for Eyes: "Wavefront-guided LASIK improves clarity, glare problems
HealthDayNews -- Wavefront-guided LASIK provides much improved contrast sensitivity compared with standard LASIK, says an Israeli study in the March issue of Ophthalmology.
Contrast sensitivity refers to the eyes' ability to detect subtle shades of gray between an object and its background.
In this study, 24 eyes of 13 people were treated with wavefront-guided LASIK and 22 eyes of 12 people were treated with standard LASIK. "

Mars: A Water World? Evidence Mounts, But Scientists Remain Tight-Lipped: "PASADENA, California -- Evidence that suggests Mars was once a water-rich world is mounting as scientists scrutinize data from the Mars Exploration rover, Opportunity, busily at work in a small crater at Meridiani Planum. That information may well be leading to a biological bombshell of a finding that the red planet has been, and could well be now, an extraterrestrial home for life.
There is a palpable buzz here at the Jet Propulsion Laboratory (JPL) in Pasadena, California that something wonderful is about to happen in the exploration of Mars.

In a small patch of Martian soil, scientists see spheres and fragmented pebbles, sand grains and finer material, and a range of colors suggesting different compositions.

Opportunity made this close-up images of spherules embedded in the wall of a trench it dug with one wheel. These spheres are more reflective than those previously found on the Martian surface.
