Early exposure to common weed killer impairs amphibian development

... than normal, compared with 2% to 3% for the two control groups. ectopic Cell Death The Tufts scientists also examined atrazine exposed ... we observe suggest that atrazine may cause tissue malformation by inducing ectopic programmed cell death, either directly or indirectly through a mechanism ...

Ovarian transplantation: First baby is born after a new technique

... were retrieved and produced 16 embryos, which in turn produced seven blastocysts. Unfortunately the first time round this patient developed an ectopic pregnancy, but she is now pregnant again." The technique was developed by Dr. Piver and his team, he told the conference. "This is the first time ...

UTSA wins San Antonio Area Foundation grant to further chlamydia research

... the disease generally progresses without exhibiting noticeable symptoms. Left untreated, chlamydia infections can do severe damage in women, causing ectopic pregnancies, pelvic inflammatory disease and even infertility. In men, complications can occur but are generally less severe. Murthy, a ...

7th annual [BC]2 Basel Computational Biology Conference 'Molecular Evolution' June 18-19, 2009

... and his collaborators. The demonstration that targeted expression of one and the same master control gene, that is, Pax6 can induce the formation of ectopic eyes in both insects and vertebrates, necessitates a reconsideration of the dogma of a polyphyletic origin of the various eye types in all the animal ...

UTSA, Health Science Center collaborate with Merck & Co. to develop chlamydia vaccine

... because they are not aware they have the infection. Long-term C. trachomatis infection in females can lead to pelvic inflammatory disease, ectopic pregnancy, serious complications for newborn infants and infertility. Macrolide (erythromycin-like) antibiotics can successfully eradicate the ...

Researchers find signal that switches on eye development -- could lead to 'eye in a dish'

... was not the only surprise. When it was introduced in some cells that formed body parts outside the head area it could still produce an additional ectopic eye leading to tadpoles with an additional eye in their side, abdomen or even along their tail. E-NTPDase2 quickly latches on to ATP converting it ...

News tips from the Journal of Neuroscience

... of ERM protein expression by small interfering RNA decreased the density and length of filopodia while accelerating spine maturation, whereas ectopic expression of constitutively active ezrin induced the formation of dendritic filopodia. KisspeptinGPR54 Signaling in Sexual Differentiation ...

The synapse is a shotgun

... broader neurotransmitter distribution is called ectopic release. "We can only be sure of data on this ... we are confident that this evidence points to ectopic release, and this means that you can't really ... right now," he said. "There is speculation that ectopic release represents some sort of spillover that ...

Research identifies protein that signals flowering in squash plants

... to confounding results. The authors found that C. moschata plants could be induced to flower under the normally non-inducing LD conditions following ectopic expression of FT by the ZYMV vector. Analysis of such induced plants showed that the infection zone of ZYMV was not coincident with the plant’s ...

Malignant melanoma cells secrete protein required for embryo formation

... cells into developing zebrafish embryos, which were used as "biosensors" for tumor cell-derived signals, and were consequently able to induce ectopic (abnormal) embryonic skull and backbone (axes) formation. "This finding highlights the convergence of tumorigenic and embryonic signaling ...

Fruit fly research set to revolutionize study of birth defects

... by a widely-prescribed drug known to cause birth defects. Methotrexate (MTX), a popular cancer-fighting drug also used to treat psoriasis, ectopic pregnancies, rheumatoid arthritis, and lupus, lasts a long time in the body and causes birth defects in children from women who have it in their ...

Harmful chemicals may reprogram gene response to estrogen

... and premature deliveries. Daughters of women who used DES are at increased risk for reproductive tract abnormalities, pregnancy complications such as ectopic pregnancies and preterm deliveries, infertility, and a rare vaginal and cervical cancer called clear-cell adenocarcinoma. Other research conducted by ...

Hirsute Or Hairless? Two Proteins May Spell The Difference

... knockout mice lacking TGF-β2 but not from their nonmutant littermates. Conversely, transgenic mice with elevated TGF-β2 signaling activity displayed ectopic expression of Snail. Knockout mice lacking TGF-β2 also showed higher levels of E-cadherin—normally down-regulated by Snail—than their nonmutant ...
