The Influence of Dietary Lysine on Yellow Perch Female Reproductive Performance and the Quality of Eggs

The objectives of this study were to (1) evaluate if dietary lysine (Lys) has an effect on the free amino acid (FAA) pool of Yellow Perch Perca flavescens eggs, and (2) determine how dietary Lys influences the reproductive performance and eggs fertilization rate (embryo survival) of female Yellow Perch. Two-year-old Yellow Perch of initial size of approximately 75 g were randomly distributed into six 400-L tanks at 32 +/- 1 fish per tank. This experiment included two wheat gluten-based diets in triplicate Lys-deficient ([-] Lys) and Lys-supplemented ([+]Lys; 2.23% in dry feed) diets. Females from the reference group were fed a commercial diet. Females from reference, (+) Lys, and (-) Lys groups were stripped and their eggs divided into 0.4-1.2-g portions and mixed with sperm (21.4 +/- 4.3 mu L) from either reference, (+) Lys, or (-) Lys males. The mean weight of Yellow Perch females and mean total weight of ovulated eggs were the greatest in the reference group compared with both (+) Lys and (-) Lys groups. There were no differences in the ratio of weight of eggs to female body weight as well as egg size among groups. There was no difference among treatments in the concentration of free amino acids except glutamic and aspartic acids in Yellow Perch eggs. There was significant effect of female dietary treatments on the egg fertilization rate averaged across all males. The higher fertilization rate was observed in the reference and (+) Lys groups compared with the (-) Lys group. The effect of female dietary treatment on the egg survival was also dependent on the dietary treatment of males.

Diabetes mellitus e esteatose hepática em ratos: efeitos de um protocolo de treinamento aeróbio

The present study aimed to analyze the effects of exercise performed at aerobic/anaerobic transition on non-alcoholic hepatic steatosis (NAHS) markers in diabetic rats. Adult (60 days) male Wistar rats were divided into 4 groups: sedentary control (SC), trained control (TC), sedentary diabetic (i.v. alloxan injection) (SD) and trained diabetic (TD). At the beginning of the experiment, all the animals were submitted to maximal lactate steady state test (MLSS) in order to identify the aerobic/anaerobic metabolic transition during swimming exercise. The trained groups were submitted to swimming, supporting overloads (% of body weight – b.w.) equivalent to MLSS intensity, 1h/day, 5 days/week, during 8 weeks. We analyzed: serum ALT, AST, albumin, glucose and free fat acids (FFA), body weight and total lipid concentrations in the liver. The diabetic groups showed higher (ANOVA two-way, p<0.05) serum glucose (SD=200% and TD= 150%) and weight loss (SD= 15.0% and TD= 8.5%) compared to controls and the SD showed higher glucose concentration and weight loss when compared to TD. The work load (% b.w.) equivalent to the MLSS was lower in TD (4.7%) than in TC (5.6%) group. The NAHS markers (U/L) did not show... (Complete abstract click electronic access below)

Mapeamento de áreas susceptíveis para implantação de aterro sanitário no município de Rio Claro, SP

The inadequate disposal of municipal waste is one of the biggest environmental problems. The lack of long public politics makes this problem a challenge to their administrators. Finding a place for the disposal of waste is an easy task and the present work looks forward to a better understanding about the concepts involved in order to choose favorable areas for the development of sanitary landfills, minimizing environmental impacts. In this line of thought several areas in Rio Claro`s region were evaluated according to the environmental terms. The areas which were classified as good or almost good will have a more elaborated study such as field works, evaluation and understanding of the concepts analyzed so that there aren’t any waste of money, work, social and environmental waste in the area. These areas were analyzed according to secondary data such as geological and pedological formation and primary studies such as the assumption of the reality as showed in the map will be made in order to acquire better results.

Corrupción en el senado brasileño: síntoma de una crisis de larga duración

La crisis del Senado brasileño, iniciada con las acusaciones de corrupción contra su presidente, se propagó al Poder Legislativo e incluso al Ejecutivo. El artículo sostiene que se trata del reflejo de una crisis general de los partidos políticos y de los parlamentos modernos, resultado de las presiones combinadas del decisionismo gubernamental y la espontaneidad social, que limitan la capacidad de acción del Legislativo. En el fondo, esto es una consecuencia de una situación de malestar institucional más amplia, una crisis de subjetividad política, en la que los sistemas políticos se vuelven incapaces de interactuar con la cultura y la sociedad producidas por los nuevos términos de la vida globalizada.

Proposed Updates to the List of Recognised Species of Cetaceans

Addition of three species to the list is recommended based on recent literature. (Orcaella brevirostris) has been split into the Irrawaddy dolphin (O. brevirostris) and the Australian snubfin dolphin (O. heinsohni). Sotalia fluviatilis has been split into the riverine tucuxi (S. fluviatilis) and the marine "costero" (S. guianensis). Evidence to support both of these splits is convincing, and we recommend that they be recognized in the list. The existence of the Bryde's-whale-like species described in 2003 as Balaenoptera omurai has been confirmed with additional genetic (nuclear) data. While the species clearly exists, the nomenclature is still unsettled because the genetic identity of the holotype specimen of Balaenoptera edeni has not yet been determined. However, the name B. omurai is gaining wide usage in application to the new species, and we propose that it be used provisionally by the Scientific Committee pending the genetic identification of the B. edeni holotype. We recommend that India be urged to facilitate the identification. We recommend continued use of the name Balaenoptera edeni provisionally for both the "ordinary" large form and the small coastal form, recognizing that further genetic and morphological research may justify recognition of two species: B. brydei and B. edeni. We also recommend that any new specimen be referred to B. omurai only after its mtDNA has been sequenced and found to support the identification.

Levels of persistent organic pollutants and residual pattern of DDTs in small cetaceans from the coast of Sao Paulo, Brazil

The State of Sao Paulo is the most developed area in Brazil and was impacted by persistent organic pollutants for several decades. This study investigated organochlorines in five species of small cetaceans (Pontoporia blainvillei, Stenella frontalis, Sotalia guianensis, Tursiops truncatus and Steno bredanensis) found dead along the coast of Sao Paulo between 1997 and 2003. DDTs (15.9 mu g g(-1) lipid: mean for all pooled individuals) and PCBs (8.08 mu g g(-1)) exhibited the highest concentrations in the animals, reflecting large amounts formerly used in Brazil. Lower levels of mirex (0.149 mu g g(-1)), HCB (0.051 mu g g(-1)), CHLs (0.008 mu g g(-1)) and HCHs (0.007 mu g g(-1)) were detected in all species. Residual pattern of DDTs in dolphins suggests that o,p`-DDT is more recalcitrant than p,p`-DDT in the body of the animals and/or the environment. In contrast to p,p`-DDT, residues of o,p`-DDT seem to be preferentially converted into o,p`-DDD rather than op-DDE. (C) 2010 Elsevier Ltd. All rights reserved.

Identifizierung, Expression und Charakterisierung des Nanos-verwandten Proteins aus dem marinen Schwamm Suberites domuncula

Im Rahmen dieser Arbeit konnte in dem marinen Schwamm Suberites domuncula ein Gen identifiziert werden, dessen C-terminale konservierte Domäne eine hohe Sequenzähnlichkeit zu den Zinkfingerdomänen der Nanos-Proteine aufweist. Weiter konnte ein N-terminales Sequenzmotiv identifiziert werden, das eine hohe Sequenzidentität zu den konservierten NIM Motiven (CNOT1-interagierendes-Motiv) von Nanos zeigt. Nach der Klonierung der cDNA erfolgte die Expression des als Sd_nrp bezeichneten Proteins in E. coli Bakterien, für dessen 231 Aminosäuren umfassende Polypeptidkette eine theoretische Molekülmasse von 25.8 kDa berechnet wurde. Anschließend gelang ein Nachweis des Proteins mithilfe eines polyklonalen, gegen Sd_nrp gerichteten Antikörpers in drei Gewebetypen, dem Pinacoderm, den Primmorphen (3D-Zellaggregate) und den Gemmulae (Dauerstadien der Schwämme). Dabei konnte die höchste Expression von Sd_nrp in den als totipotent geltenden Stammzellen der Schwämme, den Archaeocyten innerhalb der Gemmulae beobachtet werden. Die Identifizierung der Zellstrukturen, erfolgte dabei aufgrund morphologischer Vergleiche. Speziell die Merkmale der Zellen in den Gemmulae, der große Nukleus, die amöboide Form sowie die granulären Reservesubstanzen, entsprechen den typischen morphologischen Eigenschaften der Archaeocyten, und bestätigen die Interpretation der Ergebnisse. Weiter konnte mit Hilfe des Anti-Sd_nrp Antikörpers das native Protein in Proteinextrakten aus Gewebe adulter Tiere nachgewiesen werden. Die vergleichende Sequenzanalyse von Sd_nrp mit dem Nanos-verwandten Protein der Schwammspezies Ephydatia fluviatilis und die phylogenetische Stammbaum-Analyse mit Nanos-Homologen unterschiedlicher Invertebraten und Vertebraten lässt die Schlussfolgerung zu, dass es sich bei dem hier identifizierten Protein Sd_nrp um ein Nanos-verwandtes Protein handelt. Darüber hinaus konnte anhand eines Homologiemodells bestätigt werden, dass es sich bei der konservierten C-terminalen Domäne des Proteins Sd_nrp um die für Nanos-Proteine spezifische Zinkfingerstruktur mit dem konservierten Sequenzmotiv CCHC handelt. Dieses Ergebnis konnte auch bei einem Vergleich der Zinkfingerdomäne von Sd_nrp mit den Zinkfingerdomänen der Nanos-Homologen unterschiedlicher Invertebraten- und Vertebratenspezies bestätigt werden.
