In the limb bud, patterning along the anterior-posterior (A-P) axis is controlled by Sonic Hedgehog (Shh), a signaling molecule secreted by the "Zone of Polarizing Activity", an organizer tissue located in the posterior margin of the limb bud.We have found that the transcription factors GATA4 and GATA6, which are key regulators of cell identity, ar
The successful delivery of genetic material to gametes requires tightly regulated interactions between the parental chromosomes.Central to this regulation is a conserved Audio chromosomal interface called the synaptonemal complex (SC), which brings the parental chromosomes in close proximity along their length.While many of its components are known
The persistence of virtually every single species depends on both the presence of other species and the specific environmental conditions in a given location.Because in natural settings many of these conditions are unknown, research has been centered on finding the fraction of possible conditions (probability) leading to species coexistence.The foc
Cervical teratoma (CT) is Audio a rare disease which accounts for approximately three to five per cent of all teratomas in children.Airway compromise is the most serious postnatal complication of cervical teratoma.Prenatal diagnosis is crucial for early recognition of neck IBS RELIEF BIOTIC masses that could obstruct the airway.We present our exper
Nails are considered epidermal appendages, and as such, are commonly affected in patients with psoriasis, 80% of whom are likely to develop nail psoriasis as a result of their condition.Two patterns of nail disorders have been shown to be caused by psoriasis.Nail matrix involvement can result in features such as Compression Sock leukonychia, pittin
