A four-legged hen with two cloacae and three caeca
Here we report a fourteen-month-old fourlegged local hen in Nigeria with two cloacae and three caeca. The hen walked with only the normal two limbs, which were larger and cranial to the extra two limbs. The extra limbs were usually suspended in the air and pointed caudally during motion, being attached to the pygostyle by cartilage and skin tissue. Investigations of the bird were carried out us...
متن کاملEggshell and Histology Provide Insight on the Life History of a Pterosaur with Two Functional Ovaries.
The counterpart of a previously described non-pterodactyloid pterosaur with an egg revealed the presence of a second egg inside the body cavity of this gravid female. It clearly shows that pterosaurs had two functional oviducts and demonstrates that the reduction of one oviduct was not a prerequisite for developing powered flight, at least in this group. Compositional analysis of one egg sugges...

متن کاملSphingosine-1 phosphate receptor (S1p1), a critical receptor controlling human lymphocyte trafficking, is expressed in hen and human ovaries and ovarian tumors
BACKGROUND Sphingosine-1 receptor 1 (S1P1) plays a major role in regulating lymphocyte egress from peripheral lymph tissue. Lymphocyte trafficking is potentially a critical response to tumors and to tumor vaccines. Also, the receptor has been shown to influence metastasis. However, there is little information on its expression in the aged ovary or ovarian tumors. As a basis for further studies ...
متن کاملProfesseur René HEN
Selective serotonin reuptake inhibitors (SSRIs) display a delayed onset of antidepressant action of several weeks. Past work demonstrated evidence that the 5-HT4 receptor may be a direct target for treating depression and a new hope for fast acting antidepressant treatment. However, the 5-HT4 hypothesis still needs to be validated in models of anxiety/depression. We decided to investigate wheth...
