Gorlin-Goltz syndrome (GGS), also known as nevoid basal cell carcinoma syndrome, is an autosomal dominant inherited disorder with high penetrance and variable expressivity. The classic triad originally described by Gorlin and Goltz in 1960 is composed of multiple nevoid basal cell carcinomas (NBCCs), odontogenic keratocysts (OKCs) in the jaws and bifid ribs. in 1977, this triad was modified by Rayner et al, and to GGS diagnosis, the OKCs had to appear in combination with calcification of the cerebellar falx or palmar and plantar pits...

Bifid Spine is a multisystem malformation incurable and transmissible with a lot of important sequelae, some of them with treatment and some other avoidable. They affect and limit not only health but social-work life too. The main objective must be prevention. The primary prevention, meaning not occurrence, could be done by recognizing the possible etiologic factors that affect the population. This is a responsibility of health policies based in scientific evidences and expert's opinions. Secondary prevention would be to make efforts to decrease the consequences and improve newborns with bifid spine lif's quality and life expectancy...

Studies on discrete traits of the human cervical vertebrae, appearing at certain intervals during the last century, posed some questions regarding evolutionary processes that human cervical spine underwent during phylogenesis. To address questions of significance of these morphological traits we need first a good knowledge of the extent of their variation in modern humans. The aim of the current work was to integrate available data on the occurrence of various non-metric traits in the human cervical spine and search for the pattern of their distribution on intra- and inter-population levels...

Several specimens of the giant deep-sea isopod genus Bathynomus were collected by a deep-sea lander at a depth of 898 m near Hainan Island in the northern South China Sea. After careful examination, this material and the specimens collected from the Gulf of Aden, north-western Indian Ocean, previously reported as Bathynomus sp., were identified to be the same as a new species to the genus. Bathynomus jamesi sp. nov. can be distinguished from the congeners by: the distal margin of pleotelson with 11 or 13 short straight spines and central spine not bifid; uropodal endopod and exopod with distolateral corner slightly pronounced; clypeus with lateral margins concave; and antennal flagellum extending when extended posteriorly reaches the pereonite 3...

The Klippel-Feil syndrome is a congenital malformation of the skull flap involving complex cervical vertebrae and organs, characterized by a classic triad: short neck, limitation of movement of the head due to cervical spine fusion and low hairline in occipital region. It results from an error in the axial skeleton segmentation of the embryo; its incidence is estimated at 1/40,000-42,000 births and predominates in females. The aim of this paper is to describe the clinical picture of a patient with Klippel-Feil syndrome and multiple malformations, including tracheoesophageal fistula, bifid thumb and intracranial lipomas/angiolipomas,that have not been previously described in the syndrome, so it is considered an exceptional finding...

Nematodes belonging to genus Hedruris Nitzsch, 1821 (Nematoda: Hedruridae) were found in the stomach of the freshwater fish Oligosarcus jenynsii (Günther, 1864) (Characidae) from a shallow eutrophic lake in Argentina. Morphological comparisons with congeneric relatives showed that these nematodes belong to a new species, for which H. bifida n. sp. is proposed. Hedruris bifida n. sp. can be distinguished from its congeners by the following combination of characters: bifid deirids, absence of precloacal papillae and nine pairs of postcloacal papillae and non-mammillated eggs...

The widespread tropical gobionelline fish genus Oxyurichthys is monophyletic due to its species sharing two characters considered derived within the Stenogobius Group of the Gobionellinae (Gobioidei: Gobiidae), a transversely broadened (spatulate) third neural spine that is usually bifid, and no preopercular cephalic lateralis canal. It is most closely related to Oligolepis, also of the Indo-west Pacific, and Ctenogobius, an Atlantic-eastern Pacific genus. Sixteen valid species of Oxyurichthys are redescribed and illustrated and four new species are described, O...

BACKGROUND: Aneurysms affecting the aorta are a common condition associated with high mortality as a result of aortic dissection or rupture. Investigations of the pathogenic mechanisms involved in syndromic types of thoracic aortic aneurysms, such as Marfan and Loeys-Dietz syndromes, have revealed an important contribution of disturbed transforming growth factor (TGF)-β signaling. OBJECTIVES: This study sought to discover a novel gene causing syndromic aortic aneurysms in order to unravel the underlying pathogenesis...

Archamia is restricted to a single species, A. bleekeri. A recently described genus, Kurtamia, a reference to a suggested relationship with the enigmatic Kurtus, is the junior synonym of Archamia. Kurtamia bykhovskyi is a junior synonym of A. bleekeri. Archamia is redescribed using osteological, color pattern, pore and free neuromast patterns supplementing those characters used in other publications noting clear differences between A. bleekeri and all other species formerly in that genus. The new genus Taeniamia, type species Archamia leai contains the remaining species...
