Hyphessobrycon klausannisp. n. is described from small drainages of the upper Guaviare River (Orinoco River Basin) in Colombia. It differs from all congeners by having a wide, conspicuous, dark lateral stripe extending from the anterior margin of the eye across the body and continued through the middle caudal-fin rays, and that covers (vertically) three or four horizontal scale rows. It also di...

OBJECTIVE AND IMPORTANCE Compression of the cerebral peduncle against the tentorial incisura contralateral to a supratentorial mass lesion, the so-called Kernohan-Woltman notch phenomenon, can be an important cause of false localizing motor signs. Here, we demonstrate a case in which clinical, radiological, and electrophysiological findings were used together to define this syndrome. CLINICAL...

This report describes the case of two male HIV-positive patients who were not receiving treatment and whose diagnosis was confirmed by serology testing. Both developed midbrain stroke syndrome structural injury, whichwas caused a central nervous system infection due to cerebral toxoplasmosis, verified brain magnetic resonance imaging. condition cerebrospinal fluid testing.Weber’s is very rare t...

Pollination is one of the most decisive practices in cocoa cultivation; therefore, to determine self-compatibility and evaluate morphology flower, it was carried out experimental farm "La Represa", Quevedo, Ecuador. For this purpose, a completely randomized DCA design used, with forty treatments, considering treatments hybrids three repetitions. Tukey's multiple range test (P≤0.05) applied diff...

A 43-year-old man was admitted to our hospital for polypectomy because of multiple colonic polyps. He had no history of hemorrhage or abdominal trauma, and was not being treated with anticoagulant therapy. His laboratory results, including coagulation testing, were all normal. A ball-like polyp was identified in the descending colon (●" Fig.1a) and was removed using a snare to leave a 10-mm ped...

Rachises of grape (Vitis vinifera L.) clusters that appeared healthy or displayed symptoms of the ripening disorders berry shrivel (BS) or bunch-stem necrosis (BSN) were treated with the cellular viability stain fluorescein diacetate and examined by confocal microscopy. Clusters with BS and BSN symptoms experienced a decrease of cell viability throughout the rachis, and their berries contained ...

Neurogenesis in the rat olfactory peduncle was examined with [3H]thymidine autoradiography. Animals in the prenatal groups were the offspring of pregnant females given an injection of [3H]thymidine on two consecutive gestation days. Nine groups of embryos were exposed to [3H]thymidine on embryonic days (E) E13-E14, E14-E15,...E21-E22, respectively. One group of postnatal animals was given four ...

Axial patterning of the aboral end of the hydra body column was examined using expression data from two genes. One, shin guard, is a novel receptor protein-tyrosine kinase gene expressed in the ectoderm of the peduncle, the end of the body column adjacent to the basal disk. The other gene, manacle, is a paired-like homeobox gene expressed in differentiating basal disk ectoderm. During regenerat...

Two species of the cumacean genus Atlantocuma from the southern coast of Honshu, Japan, 781–861 m depth, A. gamoi sp. nov. and A. ojii sp. nov., and Pseudopicrocuma japonicum gen et sp. nov. from Nansei Islands, 566–1769 m depth, are described. Atlantocuma gamoi is characterized by (1) carapace elevated in preparatory and ovigerous female, (2) antero-lateral angle of carapace with 3 teeth in fe...
