(13) Dictated by underlying physicochemical constraints, deceived at times by the lulling tones of the siren entropy, and constantly vulnerable to the vagaries of other more pervasive forms of biological networking and information transfer encoded in the genes of virus and invading microorganisms, protein biorecognition in higher life forms, and particularly in mammals, represents the finely tuned molecular avenues for the genome to transfer its information to the next generation.
(14) It encodes a homeobox gene closely related to the developmentally regulated homeotic genes of flies and mammals.
(15) Based on the fact that all hibernators, at their regulated minimal body temperature, display a uniform turnover rate, related to body weight, the hypothesis is developed that cold tolerance of mammals is generally limited by a common specific minimal metabolic rate, which larger organisms, because of their lower basal metabolism, already attain in less profound hypothermia.
(16) Based on morphological, virological, biochemical and molecular biological data, it is proposed that the presence of endogenous retrovirus particles in the placental cytotrophoblasts of many mammals is indicative of some beneficial action provided by the virus in relation to cell fusion, syncytiotrophoblast formation and the creation of the placenta.
(17) Thus, the possibility exists that androgen secretion in some chelonian systems may exhibit a high degree of LH specificity like that of mammals and birds.
(18) Chlorinated ethylenes are metabolized in mammals, as a first step, to epoxides.
(19) This agrees with previous ultrastructural observations that, in small mammals, neither basement membranes nor large connective tissue spaces are found inside enteric ganglia.
(20) In recent studies, we have found that Gal alpha 1----3Gal beta 1----4GlcNAc residues are abundant on red cells and nucleated cells of nonprimate mammals, prosimians, and New World monkeys, but their expression is diminished in Old World monkeys, apes, and humans.
Proboscidea
Definition:
(n. pl.) An order of large mammals including the elephants and mastodons.
Example Sentences:
(1) Various pathways of development and different functional loading define existence of several modifications of the MSH: a) the medial part of the muscle develops (Didelphys, Rodentia, Insectivora, Proboscidea, Dama dama, Capreolus capreolus; b) the lateral part of the musculus develops (Lagomorpha, Canis lupus, Ursidae, Felidae, Pinnipedia, Cavicornia); c) both parts of the musculus develop, determining position of the m. digastricus between these two parts (Alces alces, Pseudaxis sica, Cervus elaphus, Macaca rhesus, Erythrocebus patas, Perissodastyla).
(2) In Perissodactyla, Artiodactyla and Proboscidea, the fibrinogen level was abnormal more often than the neutrophil count.
(3) Inspection of the amino acid differences among hemoglobin sequences of a wide range of mammalian species suggested that at alpha 19, alpha 110, alpha 111, beta 23, beta 44, and beta 56, synapomorphies group manatee (Trichechus inungius, Sirenia), Indian and African elephant (Elephas maximus and Loxodonta africana, Proboscidea), and rock hyrax (Procavia habessinica, Hyracoidea) into a monophyletic clade.
