Multihormonal islet cell carcinoma in a greater bushbaby (Galago crassicaudatus argentatus).
the synthesis or assembly of the molecules of compact myelin. Blakemore et a1.l reported that protein and lipid analyses of myelin from affected white substance were not abnormal except for some lowering of total protein content. Internodal myelin and much of that surrounding the paranodes appears normal. Some circumferential thinning of myelin sheaths has been described, but no lesions of the ...
متن کاملSomatic Koniocortex in the Prosimian Galago
Microelectrode mapping methods were used to determine the organization of somatosensory cortex in galagos, a prosimian primate. A systematic representation of the controlateral body surface was found within somatic koniocortex with an organization comparable to that of Area 3b ofparietal cortex of monkeys (S-I proper) and primary somatosensory cortex (S-I) of other mammals. Limited studies of t...
متن کاملCharacterization of a third major SINE family of repetitive sequences in the galago genome.
In addition to the Alu family of short interspersed repetitive DNA elements (SINEs), we have previously characterized one other repetitive DNA family (Type II) in the prosimian, Galago crassicaudatus. We present here a detailed analysis of seventeen members of a third galago SINE family designated as the Monomer family. Both the Monomer and Type II families are shown to be specific for the gala...
متن کاملNaturally Occurring Ehrlichia chaffeensis Infection in Two Prosimian Primate Species: Ring-tailed Lemurs (Lemur catta) and Ruffed Lemurs (Varecia variegata)
A naturally occurring infection of Ehrlichia chaffeensis in lemurs is described. DNA of Ehrlichia chaffeensis was identified by polymerase chain reaction in peripheral blood from six of eight clinically ill lemurs. Organisms were cultured from the blood of one lemur exhibiting clinical and hematologic abnormalities similar to those of humans infected with E. chaffeensis.
متن کاملMating season aggression and fecal testosterone levels in male ring-tailed lemurs (Lemur catta).
The challenge hypothesis (J. C. Wingfield, R. E. Hegner, B. G. Ball, and A. M. Duffy, 1990, Am. Nat. 136, 829-846) proposes that in birds, reptiles, and fish, "the frequency or intensity of reproductive aggression as an effect of T[estosterone] is strongest in situations of social instability, such as during the formation of dominance relationships, the establishment of territorial boundaries, ...
