Stem cell therapy for developing new trachea using Tissue engineering

Researchers from Children’s Hospital of Boston have reconstructed defective windpipes using tissue engineering in fetal lambs. The researchers used amniotic fluid for growing the sections of cartilage tube // and then implanted these living tissues into lambs, while they were in the womb. This technique of tissue engineering is used for altering birth defects. Undifferentiated stem cell from amni...

Trachoma cannot be obliterated with just one dose of antibiotic

A study carried in eight Ethiopian villages for two years found that a single dose of an antibiotic is insufficient to nip infection causing trachoma, which happens to be the// primary cause of blindness. A previous study in one Tanzanian village had seemed to show that a single distribution exercise of one antibiotic was enough to completely negate the infection. A new study has sugg...

New Test For Detecting Trachoma

Trachoma, an infection caused by Chlamydia trachomatis bacteria leads to blindness in over one million women and children. Although the infection is very treatable there is a difficulty// in diagnosing it accurately especially in remote areas. Now scientists have developed a ‘sight-saving’ dipstick test that can give results in under half an hour. In a trial involving over 600 Masai c...

Blindness And Trachoma

A study in the September 27 issue of JAMA says that using antibiotic azithromycin to treat trachoma in Vietnam had increased the risk of reinfections.// Trachoma is an infectious disease where scar tissue forms underneath the eyelid. In 1995 the WHO reported that 15 percent of all blindness was caused by trachoma. This was the second biggest cause of blindness after cataract. At that t...

Trachoma not Curable by Antibiotics Alone

A study conducted in Vietnam has indicated that antibiotic therapy against Trachoma is not effective in the long term. When children affected with trachoma //(second leading cause of blindness after cataract) were treated with azithromycin, it was seen that there was only a short-lived improvement. Dr. Deborah Dean, senior scientist at Children's Hospital Oakland Research Institute in California...

Newly Identified Strains Of Chlamydia Trachomatis – A Gateway To New Disease

Chlamydia trachomatis, a bacterium, which is one of the leading cause for sexually transmitted diseases and the second leading cause for blindness globally, is said to be// evolving at a rate faster than scientists would have imagined. The scientists from Children’s Hospital Oakland Research Institute (CHORI) were the first to conclude this with the help of a new study. The Scientist...
