| Males of sexually dimorphic anthribid species display structural modifications that suggest sexual selection. Polyphenism, which is expressed through morphological and behavioral novelties, is an important component of the evolutionary process of these beetles. In this study, we endeavored to ascertain the presence of variations in selected monomorphic traits, polyphenism in males, and variation in structures associated with sexual dimorphism and allometric patterns in two species: Systaltocerus platyrhynus Labram & Imhoff, 1840 and Hypselotropis prasinata (Fahraeus, 1839). To that end, we used Principal Components Analysis (PCA) and Canonical Variate analysis (CVA) to statistically analyze 26 measurements of 91 specimens. The PCA discriminated... |

| The study was carried out with the objective of verifying which measures and morphometric ratios are more directly related to the body yield of Nile tilapia, Oreochromis niloticus, in two weight classes. Data were analyzed from 257 specimens of tilapia divided into two weight classes: p1 = 400 to 599 g and p2 = 600 to 900 g. The morphometric measurements standard length (SL), head length (HL), body height (BH) and body width (BW), and the ratios of these measures (HL / SL, BH / SL, BW / SL, HL / BH, BW / BH, BW / HL) were evaluated. The following body yields were calculated: carcass (RCAR), fillet (RFILE) and head (RCAB). The data were initially submitted to the "stepwise" procedure to eliminate problems of multicollinearity among the morphometric... |

| The purpose of this work is to calibrate a not expensive microscope to be applied in Optical Disector estimation. The evaluation of "Z-axis" bias and the "Z-axis" calibration were made utilizing a cover slip and a "manual digimatic outside micrometer scale" (Mitutoyo, Japan). Calibrating the cover slip we performed the calibration of the "Z-axis" of a microscope. In the cover slip two lines were painted with different colors using a pen glass. A blue line was painted on the up surface and another line (red) on the bottom surface of the cover slip forming a cross. Two metal rings with one palette welded in each were adapted in the microscope. Other palette was welded in the gross focuses in order to restrict the route of the fine focuses (Z-axis study)... |

| In restinga areas of Marambaia, Rio de Janeiro, we recorded nine species of lizards, grouped in four families. The morphometric analysis suggested an invasion-structured pattern, with two distinct groups of species in the community: the "ground-runners", composed of animals with robust bodies and long limbs, represented by Tropidurus torquatus (Wied, 1820), Ameiva ameiva (Linnaeus, 1758), Liolaemus lutzae Mertens, 1938, Cnemidophorus littoralis Rocha, Araujo, Vrcibradic & Costa, 2000 and Tupinambis merianae (Duméril & Bibron, 1839); and the "hiders", composed of small-bodied animals with short limbs, represented by Hemidactylus mabouia (Moreau de Jonnès, 1818), Gymnodactylus darwinii (Gray, 1845), Mabuya agilis (Raddi, 1823) and M.... |

| Cadmium in the air, drinking water and food has the potential to affect the health of people, mainly those who live in highly industrialized regions. Cadmium affects placental functions, can cross the placental barrier and directly disturbs fetal development. It is also excreted into milk. The organism is particularly susceptible to cadmium exposure at perinatal period. The effect on rat maxillary molar junctional epithelium a continuous exposure to drinking water containing low level of cadmium during lactation was studied. Female rats received drinking water ad libitum containing 300 mg/l CdCl2 throughout the whole lactation. Control animals received a similar volume of water without cadmium. Lactent rats (21 day-old) were killed by lethal dose of... |

| ABSTRACT This study aimed to verify whether the criterion of exhibition contests adopted for Campolina and Mangalarga Marchador breeds has been successful in recent years, i.e., if the subsequent generations have the morphology recommended by the standard of the breed allied with high-quality marcha, a four-beat ambling gait. The classifications achieved by each horse during national horse shows in morphology and gait contests underwent Spearman's correlation to verify the number of contests with a correlation between the classifications in the two judgments and those with no correlation. Next, the number of contests with or without such correlation underwent a frequency distribution test considering the variables breed, year, age, marcha category, and... |

| The objective of this study was the evaluation of aspartame effects on morphometric alterations of the glomerulus, proximal and distal convoluted tubules and collecting ducts of the rat fetal kidney during organogénesis. Fifteen pregnant rats averaging 24 g body weight, were divided into 3 groups (n=5 each) of controls, rats treated with aspartame exposed to room temperature and rats treated with aspartame heated to 40°C. Animals were given 14mg / kg aspartame by the intragastric route on the 9th, 10th, and 11th days of pregnancy. Karyometric and stereological techniques estimated morphological changes. A significant decrease of fetal body weight was observed in the group given aspartame kept at room temperature, compared to controls. Karyometry permitted... |

| The aim of this study was to evaluate the possible beneficial effects of Catuaba Cristal® (CC), an alcoholic drink made from wine and Erythroxylum catuaba Ar. Cam on testis. Wistar rats either received CC solution (n=8) or water (n=9). Results showed significant body weight reduction within the CC group, although, no weight changes were observed for liver, kidney, testis, epididymis, seminal vesicle and prostate. The volumetric proportion and volume of interstitial tissue and lymphatic space were reduced in the treated group. In the CC group, although the nuclear volume of Leydig cells (LC) decreased, the number of LC per testis increased. These results suggested that CC had no beneficial effect on spermatogenesis of Wistar rats. |

| The purpose of this study was to evaluate the effects of maternal protein and energy restriction during lactation on the body weight and tibiae dimensions of pups at aging. At parturition, Wistar rat dams were randomly assigned to the following groups: 1) control group (C) - free access to a standard laboratory diet containing 23% protein, 2) protein-energy restricted group (PR) - free access to an isoenergetic, protein-restricted diet containing 8% protein, and 3) energy-restricted group (ER) - fed restricted amounts of a standard laboratory diet. At weaning, all pups were separated of dams and received free access to a standard laboratory diet containing 23% protein until 180 days when the rats were anesthetized and sacrificed. The dimensions of excised... |

| The contents of soybean can modify the structure of the reproductive system, especially, when consumed for prolonged periods. In this study, we evaluated the effects of the consumption of transgenic soybean on rat penis morphology after prolonged use. Wistar rats (n = 30) were divided into three groups according to diet: Transgenic Soybean (TS) group, Organic Soybean (OS) group and Control (C) group. After 455 days of intake, the rats were sacrificed and the penises were excised and fixed in formalin for subsequent histological processing. The samples were stained with hematoxylin and eosin, Weigerts resorcin-fuchsin stain, and picrosirius red with polarization. The images were scanned for the histomorphometric analyses of the corpora cavernosa, corpus... |

| The study of larvae nutritional condition allows to assess the physiologic state that reflects the environmental situation they were exposed to. It represents a useful instrument to determine favourable nursery areas, provides tools for the management of a population subject to fishing and furnishes information to establish appropriate closed areas and periods. The material analyzed derived from three cruises carried out to assess Argentine anchovy Northern stock during the 2003, 2004 and 2006 reproductive peak (SW Atlantic Ocean, Argentine Sea). The objective of this work was to study the nutritional status of Argentine anchovy first feeding larvae caught in the coastal and mid-shelf of the Río de la Plata River maritime front in relation to the... |
