A Rare Variation of the Retro-Aortic Left Renal Vein with Anastomotic Afluent from Inferior Mesenteric Vein International Journal of Morphology
Andrade,F. M.; Rocha,R. P.; Pereira,H. M.; Fernandes,R. M. P.; Babinski,M. A..
We report an uncommon anatomical variations of the left renal vein was found on dissected specimen in an elderly male cadaver: a retroaortic left renal vein. No other vascular anomalies were noted in this specimen. The anomaly result may be related to a particular pattern of left inferior vena cava. The abnormality have to be known for it may be undetected or be misleading in imaging. This anatomical curiosity should be kept in mind by clinicians and academics that may manipulate this anatomical area

Anomalies, Aneurysm and Histology of the Middle Cerebral Artery in Nigerian Africans International Journal of Morphology
Idowu,O. E; Shokunbi,M.T; Malomo,A. O; Akang,E. E. U.
The histology of the middle cerebral artery (MCA) in Nigerian Africans has not been previously studied. One hundred MCAs obtained at autopsy from fifty adult Nigerians were studied. The vessels were processed and stained with Ehrlich's haematoxylin and eosin, elastic Van Gieson and Masson's trichrome stains. Early branches were given off before the perforators in two middle cerebral arteries, and there was one accessory MCA, making an incidence of anomalies of 3%. No aneurysm was observed in any of the cases. The internal elastic laminas were well developed but the external elastic laminas of the vessels were poorly developed. Cióse to the bif urcations the túnica media tapered gradually and at the bif urcations, the túnica media was completely deficient...

Anomalous Origin of Left Internal Thoracic Artery from the Second Intercostal Artery International Journal of Morphology
Mehmet,O. C; Bahar,O. C; Pasaoglu,Ilhan.
Left internal thoracic artery (LITA) has increased importance and common use in coronary bypass grafting because of long-term better patency rate and improvement in both the duration and quality of survival of patients. LITA is a branch of the first part of the subclavian artery. We report a case in which the LITA originated from the second left intercostal artery. A 71-year-old man with a history of angina pectoris for 1 month was admitted to the hospital because of progressive increase in anginal symptoms. During the operation, it was noted that the LITA originated from the second intercostal artery. LITA used as a free graft. LITA was anastomosed to the left anterior descending coronary artery. He was free of symptoms 4 weeks after operation. To our...

Differentiating Lithogenic Supplies, Water Mass Transport, and Biological Processes On and Off the Kerguelen Plateau Using Rare Earth Element Concentrations and Neodymium Isotopic Compositions ArchiMer
Grenier, Melanie; Garcia-solsona, Ester; Lemaitre, Nolwenn; Trull, Thomas W.; Bouvier, Vincent; Nonnotte, Philippe; Van Beek, Pieter; Souhaut, Marc; Lacan, Francois; Jeandel, Catherine.
Distributions of dissolved rare earth element (REE) concentrations and neodymium isotopic compositions (expressed as epsilon(Nd)) of seawater over and off the Kerguelen Plateau in the Southern Ocean are presented. The sampling took place during the austral spring bloom in October-November 2011 (KEOPS2 project, GEOTRACES process study) and aimed to further the investigations of the KEOPS1 austral summer study in terms of sources and transport of lithogenic material, and to investigate the impact of local biogeochemical cycles on the REE distributions. The REE signature of the coastal eastern Kerguelen Islands waters was characterized by negative europium anomalies (Eu/Eu*) and negative epsilon(Nd) in filtered samples. By contrast, the unfiltered sample...

The aim of this work was to evaluate the direct protective action of oral fatty acid supplementation against the deleterious effect of hyperglycemia on maternal reproductive outcomes; fetal growth and development on female Wistar rats. The animals were distributed into four experimental groups: G1= non-diabetic without supplementation (Control group); G2= non-diabetic treated with linoleic (LA) and gammalinolenic acid (GLA) (1 mL of Gamaline-V/day); G3= diabetic without supplementation and G4= diabetic treated with LA and GLA. Diabetes was induced by streptozotocin (40 mg/kg). At day 21 of pregnancy, the gravid uterus was weighed and dissected to count the dead and live fetuses, resorption, implantation, and corpora lutea numbers. The fetuses were analyzed...

Etude des anomalies chromosomiques chez Crassostrea gigas ArchiMer
Lapegue, Sylvie; Mccombie, Helen; Leitao, Alexandra; Bouilly, Karine; Sabatier, Sebastien; Heurtebise, Serge; Boudry, Pierre; Thiriot, Catherine; Gerard, Andre.
Divers travaux menés depuis 1984 montrent qu'il existe, chez l'huître creuse Crassostrea gigas, des cellules montrant un nombre anormal de chromosomes (2n = 19, 18 ou même 17 au lieu de 2n = 20). Le niveau d'aneuploïdie est déterminé par le décompte des chromosomes à partir de suspensions cellulaires de tissu branchial. Le pourcentage de cellules aneuploïdes est toujours significativement supérieur dans les "lots de queue", c'est-à-dire les huîtres présentant des croissances plus faibles, et peut atteindre plus de 30 %. Récemment, une étude réalisée au sein du programme européen « Genephys » a démontré que plus de 50 % de la variance pour la vitesse de croissance était liée au taux d'aneuploïdie. Cependant, de nombreux points concernant ce phénomène...

Genetic investigation of swimbladder inflation anomalies in the European sea bass, Dicentrarchus labrax L. ArchiMer
Peruzzi, Stefano; Westgaard, Jon-ivar; Chatain, Beatrice.
Although the actiology of swimbladder inflation anomalies in important aquaculture species such as European sea bass D. labrax is not fully determined, culture conditions are commonly suggested as main contributory factors. Little information is available on whether swimbladder inflation has a genetic basis for its expression too. In this work, 24 full-sibling sea bass families from a 4 dams x 6 sires factorial crossing were reared under communal conditions. The larvae developing normal and abnormal (uninflated or hyper-inflated) swimbladders were genotyped at four microsatellite loci, Labrax-3, Labrax-13, Labrax-17, Labrax29, and allocated to the individual breeders. Out of 273 offspring, 97% could be assigned to a single parental pair. The genotype and...

High Prevalence of Sternal Foramen: Quantitative, Anatomical Analysis and its Clinical Implications in Acupuncture Practice International Journal of Morphology
Babinski,Marcio A; Rafael,Fábio A; Steil,Alisson D; Sousa-Rodrigues,Célio F; Sgrott,Emerson A; de Paula,Rafael Cisne; Fernandes,Rodrigo M. P.
The aim of our study was to verify the prevalence of the sternal foramen in adult cadavers and dry bones, as well as to determine its exact localization and relation to acupuncture points. One hundred eighty sternums fixed and contained in 10% formaldehyde solution were examined, of which 100 were dry bones and 80 belonged to adult cadavers. The morphometric measures were expressed in millimeters when measuring the length: 1) from jugular incision to the foramen (JI-F); 2) from sternal angle to the foramen (EA-F); 3) from xiphoid process to the foramen (XP-F). Statistical analysis was performed to compare expected vs obtained foramina frequency, using Fisher's test (p0.05 was considered significant). The results showed 16.6% sternal foramina, significant...

Ocular tentacle malformation in Deroceras reticulatum (Mollusca: Gastropoda: Agriolimacidae) Pap. Avulsos de Zool. (São Paulo)
Daglio,Eduardo Daniel; Lucía,Micaela de; Robinson,David Gwyn; Gregoric,Diego Eduardo Gutiérrez.
Abstract Malformations in animals have long been known. In gastropod, natural and induced malformations are mentioned in different systems and in ocular tentacles, mainly linked to cases of parasitism and exposure to pollutants (molluscicides and chemicals). In this study we present a new malformation not documented in the ocular tentacles of slug Deroceras reticulatum that could be due to the action of pesticides. This malformation in D. reticulatum is the first malformation to be mentioned for South America in nursery gardens.

Potencial erosivo e índice de anomalias de chuvas no polo de produção de grãos de Paragominas, Pará. Repositório Alice
COSTA, D. C.; MARTORANO, L. G.; MORAES, J. R. da S. C. de..
A erosão hídrica tem causado perdas nas camadas superficiais do solo e promovido sérios danos ambientais, econômicos e sociais em sistemas de cultivos agrícolas convencionais no Brasil. Objetivou-se com este trabalho estimar o potencial erosivo das chuvas para subsidiar estratégias de manejo sustentável no polo de produção de grãos de Paragominas. O Fator R da equação universal de perda de solos (USLE) foi calculado para identificar anos com maior ou menor potencial erosivo. Também, para identificar o padrão pluvial, utilizou-se o índice de anomalias de chuvas (IAC) para auxiliar nas avaliações em anos úmidos e secos, considerando a serie histórica referente ao período de 1985 a 2010, disponibilizada pela Agencia Nacional de Águas (ANA). Os resultados...

Short-term variability in alongshore winds and temperature off Swakopmund, Namibia, during a non-upwelling event in 1998-1999. OceanDocs
Bartholomae, Ch.; Hagen, E..
Swakopmund is a popular coastal resort in Namibia, especially during the summer holiday season when daily sea temperatures can fluctuate several degrees in a short period. Hourly measurements of the nearbottom water temperature were collected off the Swakopmund Jetty to investigate the thermal variability in relation to local winds. The thermal regime of this coastal region appears to be controlled by the locally forced Ekman offshore transport. Related changes in offshore transport led those of the surf-zone temperature by about one day. A transfer of kinetic energy from the alongshore wind into the temperature field of the nearshore zone dominated relative short time scales (hourly). The longer periods (7–9 days) are associated with the forcing of...

Use of environmental parameters to explain the variability in spawnerrecruitment OceanDocs
Kirchner, C. H.; Bartholomae, C. H.; Kreiner, A..
This study attempts to explain the variability in recruitment of sardine in the northern Benguela and to develop potential models by including environmental information to predict recruitment. Two different recruitment and spawner number datasets were available: a VPA-developed dataset, for the period 1952–1987, and data from a simple age-structured model for 1992–2007. In all, four environmental indices were used: the degree of the intrusion of the warm Angola Current into northern Namibia, termed the Angola–Benguela front index; the extent of the upwelling area off central Namibia; average sea surface temperature (SST) over the northern and central Namibian shelf; and wind stress anomalies at Lüderitz as an indicator of upwelling strength. Contrary to...

Аномалии пигментации черноморской камбалы калкана Psetta (= Scophthalmus) maxima maeotica (Pleuronectiformes: Scophthalmidae). IBSS Repository
Ханайченко, А. Н.; Гирагосов, В. Е.; Ельников, Д. В.; Данилюк, О. Н..
Впервые проведен анализ аномалий пигментации черноморской камбалы калкана Psetta (= Scophthalmus) maxima maeotica из района юго-западного шельфа Крымского п-ова. Аномалии отнесены к 2 типам: первичной и вторичной пигментации. Предложено систематизировать вариации первичной пигментации калкана и других камбалообразных по 6 категориям в зависимости от степени гипермеланизации правой стороны тела. Полная пигментация правой стороны тела калкана сопряжена с аномалиями миграции глаза. Относительное количество аномально пигментированных особей во всех проанализированных уловах 2005 – 2007 гг. составило 9.8 %. Обнаруженные аномалии предположительно индуцируются нарушением состава пищи во время поздней планктонной фазы развития калкана и закрепляются необратимо в...
