1. Kidney anatomy, histology and histometric traits associated to renosomatic index in Gymnotus inaequilabiatus (Gymnotiformes: Gymnotidae)
RESUMO Gymnotus inaequilabiatus é um peixe neotropical amplamente distribuído em áreas marginais de baías. O objetivo deste estudo foi descrever características anatômicas, histológicas e histopatológicas no rim cefálico e exócrino. Análises histométricas e a densidade volumétrica estrutural foram associadas ao índice renossomático (IRS). Frag

2. In vitro multiplication of Eucalyptus hybrid via temporary immersion bioreactor: culture media and cytokinin effects
Abstract This study aimed to assess the influence of culture medium and cytokinin type on in vitro multiplication of an Eucalyptus grandis x E. urophylla hybrid clone via temporary immersion bioreactor (TIB®). JADS, modified MS at a (NO3ˉ):(NH +) ratio, and WPM were used as liquid media; and 6-benzilaminopurine (BAP), kinetin (KIN), and thidiazuron (TDZ) w

3. Effects of low-protein diets supplemented with antioxidants on histopathology of testis and testosterone and performance of male Japanese quail ( Coturnix coturnix japonica )
ABSTRACT The present study sought to examine the effects of low-protein diets supplemented with natural and synthetic antioxidants on reproductive traits and performance of male Japanese quail. A total of 144 one-day-old quail chicks were randomly assigned to receive four different treatments, including a control diet (a basal diet) without antioxidant suppl

4. Insights into the dynamics of hind leg development in honey bee (Apis mellifera L.) queen and worker larvae - A morphology/differential gene expression analysis
Phenotypic plasticity is a hallmark of the caste systems of social insects, expressed in their life history and morphological traits. These are best studied in bees. In their co-evolution with angiosperm plants, the females of corbiculate bees have acquired a specialized structure on their hind legs for collecting pollen. In the highly eusocial bees (Apini a

5. Gross anatomy and histology of the alimentary system of Characidae (Teleostei: Ostariophysi: Characiformes) and potential phylogenetic information
A compared study of the morphology of the alimentary tract and liver of seven selected species corresponding to the main clades of the Characidae family is presented herein. Three new set of characters corresponding to 1) alimentary tract gross anatomy, 2) alimentary tract histology and 3) liver gross anatomy are evaluated as potential sources of data for fu

6. Morphology of male reproductive system of two solitary bee species (Hymenoptera: Apidae)
Bees can form all levels of social organization, from solitary to advanced eusocial societies. Although 80% of the species exist as solitary species, most researches emphasize social species. This study focuses on the description of the male reproductive system of the solitary beesThygater analis (Lepeletier) and Melitoma segmentaria (Fabricius) and searches

7. Quantitative-genetic study of muscle fibers of number and diameter in a male broiler line / Estudo genético-quantitativo de número e diâmetro de fibras musculares em linhagem macho de frangos
This research was conducted to estimate genetic and phenotypic parameters of muscle fibers of number, diameter and area, as well as of performace, carcass and meat quality traits in a male broiler line belonging to a program of selection of the type sib test, in which data from complete brothers of the individuals were selected, bred in a pedigree flock prov

8. Autosomal dominant pseudoxanthoma elasticum
Two families are described, each with a unique clinical variant of pseudoxanthoma elasticum (PXE) inherited in autosomal dominant fashion. Dominant type I PXE is characterized by a classical flexurally distributed rash, severe and frequent angina of effort, intermittent claudication and hypertension, and a very severe choroidoretinitis, often complicated by

9. Disruption of the nonneuronal tph1 gene demonstrates the importance of peripheral serotonin in cardiac function
Serotonin (5-HT) controls a wide range of biological functions. In the brain, its implication as a neurotransmitter and in the control of behavioral traits has been largely documented. At the periphery, its modulatory role in physiological processes, such as the cardiovascular function, is still poorly understood. The rate-limiting enzyme of 5-HT synthesis,

10. Traits That Influence Longevity in Mice: A Second Look
Analysis of genetic interactions in the F(2) of an intercross of (C57BL/6 X DBA/2) F(1)J revealed influences of genetic factors on life span. Females lived longer than males. Dilute brown females died sooner than females of other colors. H-2(b)/H-2(b) males died sooner than H-2(b)/H-2(d) or H-2(d)/H-2(d) males, except that among dilute brown males those of t
