A comparison was made of beta-endorphin (B-END) concentrations versus post-translation products during the perinatal period in the hypothalamus and the caudal medulla oblongata. The concentration of B-END-like immunoreactivity did not differ statistically between embryonic day 21 (E21) and postnatal day 1 (P1) in either area. There were significant differences in forms, with a shift from larger...
BACKGROUND HER2 is a membrane receptor whose overexpression is strongly associated with poor prognosis in breast carcinomas. Inhibition of HER2 activity can reduce tumor growth, which led to the development of Herceptin, an anti-HER2 monoclonal antibody (MAb) that is already in clinical use. However, the objective response rate to Herceptin monotherapy is quite low. HER2 activity can also be in...
Between embryonic day 14 (E14) and embryonic day 21 (E21), the rat neopallium develops from a relatively homogeneous band of mitotic precursor cells into a complex laminated structure containing diverse classes of neurons. In order to identify some of the molecular components underlying this process, 2-dimensional PAGE was used to compare proteins expressed before cortical neurons are born (E14...
The capacity of yolk sac (YS) utilization by the chick embryo may be affected by structural changes in the YS membrane (YSM) and by the mechanisms within its cells for digestion, absorption, and transfer of nutrients. Two experiments were conducted to examine structural and digestive changes in the YS of the broiler chick embryo; weights of embryo, YS, and YSM, as well as the total area of the ...

Animals are adapted to respond quickly to threats in their environment. In many invertebrate and some vertebrate species, the evolutionary pressures have resulted in rapidly conducting giant axons, which allow short response times. Although neural circuits mediating escape behavior are identified in several species, little attention has been paid to this behavior in the medicinal leech, a model...
Let e1, . . . , ek be complex n× n matrices such that eiej = −ejei whenever i 6= j. We conjecture that • rk(e21) + rk(e 2 2) + · · ·+ rk(e 2 k) ≤ O(n log n). We show that (i). rk(en1 ) + rk(e n 2 ) + · · ·+ rk(e n k ) ≤ O(n log n), (ii). if e21, . . . , e 2 k 6= 0 then k ≤ O(n), (iii). if e1, . . . , ek have full rank, or at least n−O(n/ log n), then k = O(log n). (i) implies that the conjectur...
