Vocalization of broilers can be used to identify their sex and genetic strain
Provedor de dados: 70
Autores: PEREIRA,ERICA M.; NÄÄS,IRENILZA DE A.; GARCIA,RODRIGO G.
In order to reach higher broiler performance, farmers target losses reduction. One way to make this possible is by rearing sexed broilers as male and female present diverse performance due to their physiological differences. Birds from different genetic strain also have a distinct performance at the same age. Considering that sexed flocks may present higher performance this study aimed to identify one-day-old chicks’ sex throughout their vocalization. This research also investigated the possibility of identifying the genetic strain by their vocalization attributes. A total of 120 chicks, half of them were from Cobb® genetic strain and the other half from Ross® genetic strain. From each group, a total of 30 were males and 30 females, which were previously...

NMR relaxometry as a potential non-invasive routine sensor for characterization of phenotype in Crassostrea gigas
Provedor de dados: 5
Autores: Davenel, Armel; Pouvreau, Stephane; Cambert, Mireille; Suquet, Marc; Mariette, Francois.
MR imaging is the most appropriate non-invasive technique for quantifying the growth of somatic and gonad tissues and to determine sex in the Pacific oyster, Crassostrea gigas. However, this technique is too costly for field studies where oysters are used as bioindicators of environmental quality or to be applied routinely in hatcheries. We have tested the ability of low Nuclear Magnetic Resonance relaxometry, a much less expensive technique, to obtain phenotype parameters that can be used to monitor the physiological state of oysters. NMR measurements were carried out at three different periods using a low field spectrometer equipped with a 50 mm diameter probe to investigate 60 oysters in their first year of maturity, which were then dissected to measure...

Dental Pulp Fibroblast and Sex Determination in Controlled Burial Conditions
Provedor de dados: 77
Autores: Sandoval,Catherine; Nuñez,Marcelo; Roa,Ignacio.
The need to identify bodies that are found as a result of disappearances with a diversity of causes, illegal burials and massive disasters, represent a wide percentage of dentistry practice on forensic research. The following study determined the performance of Barr Body Test, in fibroblasts of healthy teeth, under different conditions of burial (in vitro) with variations in pH, humidity and salinity in terms of general accuracy and sensitivity for men and women. Analyzed sample considered 47 dental pulps, taken from teeth under burial conditions during a period of a month. From dental pulps samples, 265 histological cuts valid for this study, were obtained, which were observed with an optical microscope under conventional H/E staining. Results showed a...

Skeletal remains are crucial in forensic identification of the sex, especially human skulls including the styloid process, a bony projection from the skull. Hence, the objectives of the present study were undertaken to assess the value of the styloid process for the sex identification of unknown skulls and also to investigate the prevalence of elongated styloid process in 102 human dry skulls from the northeast Thai population. As a result, the interstyloid distances at both base and tip of the styloid processes were found to be significantly different between male and female specimens, although no significant difference was found in the length of the styloid process between males and females. In addition, the occurrence of the elongated styloid process...

Performance Evaluation as a Diagnostic Test for Traditional Methods for Forensic Identification of Sex
Provedor de dados: 77
Autores: Suazo Galdames,Iván Claudio; Zavando Matamala,Daniela Alejandra; Smith,Ricardo Luiz.
This study assesses the quality, as a diagnostic test, of the main indicators of morphological sexual dimorphism through direct anthropometry, biostatistics tools and clinical epidemiology. This study used 284 skulls of adult Brazilians, of which 187 were male and 97 female. A study of the cross-evaluation of the diagnostic test was performed; it was a qualitative approach based on visual examination of 16 traditional indicators of morphological sexual dimorphism, where each indicator determined the level of accuracy, sensitivity, predictive values, likelihood ratios, and odds ratio. All indicators studied had high levels of accuracy (84.75­72.89%). The best indicators were found in traits whose formation is related to the insertion and action of major...
