Localization of sterodogenic acute regulartory (StAR) protein in testis of Thai red jungle fowl (Gallus Gallus Gallus)
Journal of Morphological Sciences, 2020Co-Authors: S. Iamsaard, A. Chaichun, W. SukhorumAbstract:Abstract Introduction: Thai red jungle fowl (Gallus Gallus Gallus) has been focusing on genetic profiles besides phenotypical features. The husbandry of this species is still limited. Basic understanding of its reproductive systems may be useful for breeding applications. Additionally, the morphology of testes and epididymis of Thai red jungle fowl has never been elucidated. Material and Methods: This study has examined the gross structure and histology of those organs of male Thai Gallus Gallus Gallus at 24th weeks (age and sexual maturity). Moreover, the localization of sterodogenic acute regulartory (StAR) protein in the testis was also performed by immunohistochemistry. Results: The results showed that the mature testes were oval shape with 1.56 ± 0.584 cm. in length and 1.20 ± 0.067 cm. in width, respectively. General histology of testes and epididymis was similar to those of maturely domestical birds. Expectedly, the StAR protein was first localized in the leydig cells of Thai red jungle fowl. Conclusion: These findings are fundamental data that may be applied to the breeding process.

one subspecies of the red junglefowl Gallus Gallus Gallus suffices as the matriarchic ancestor of all domestic breeds
Proceedings of the National Academy of Sciences of the United States of America, 1994Co-Authors: Akishinonomiya Fumihito, Tetsuo Miyake, Shinichiro Sumi, Masaru Takada, Susumu Ohno, Norio KondoAbstract:Abstract The noncoding control region of the mitochondrial DNA of various gallinaceous birds was studied with regard to its restriction fragment length polymorphism (RFLP) and sequences of the first 400 bases. Tandem duplication of the 60-base unit was established as a trait unique to the genus Gallus, which is shared neither by pheasants nor by quails. Unlike its close ally Gallus varius (green junglefowl), the red junglefowl Gallus Gallus is a genetically very diverse species; the 7.0% sequence divergence was seen between those from Thailand (G. g. Gallus and G. g. spadiceus) and the other from the Indonesian island of Java (G. g. Bankiva). Furthermore, the divergence increased to 27.83% if each transversion is regarded as an equivalent of 10 transitions. On the other hand, a mere 0.5-3.0% difference (all transitions) separated various domestic breeds of the chicken from two G. g. Gallus of Thailand, thus indicating a single domestication event in the area inhabited by this subspecies of the red junglefowl as the origin of all domestic breeds. Only transitions separated six diverse domesticated breeds. Nevertheless, a 2.75% difference was seen between RFLP type I breeds (White Leghorn and Nagoya) and a RFLP type VIII breed (Ayam Pelung). The above data suggested that although the mitochondrion of RFLP type V was the main contributor to domestication, hens of other RFLP types also contributed to this event.

What are the similarities between stress, sudden cardiac death in Gallus Gallus and sudden unexpected death in people with epilepsy
Arquivos De Neuro-psiquiatria, 2010Co-Authors: Fulvio A. Scorza, Ricardo Mario Arida, Carla A. Scorza, Ricardo De Albuquerque, Marly De Albuquerque, Vera C. Terra, Hélio Rubens Machado, Roberta M. Cysneiros, Esper A. CavalheiroAbstract:Individuals with epilepsy are at higher risk of sudden unexpected death in epilepsy (SUDEP), responsible for 7.5% to 17% of all deaths in epilepsy. Many factors are current associated with SUDEP and possible effect of stress and cardiac arrhythmia are still not clear. Sudden death syndrome (SDS) in chickens is a disease characterized by an acute death of well-nourished and seeming healthy Gallus Gallus after abrupt and brief flapping of their wings, similar to an epileptic seizure, with an incidence estimated as 0.5 to 5% in broiler chickens. A variety of nutritional and environmental factors have been included: but the exactly etiology of SDS is unknown. Studies had suggested that the hearts of broiler chickens are considerably more susceptible to arrhythmias and stress may induce ventricular arrhythmia and thus, sudden cardiac death. In this way, SDS in Gallus Gallus could be an interesting model to study SUDEP.

Could sudden death syndrome (SDS) in chickens (Gallus Gallus) be a valid animal model for sudden unexpected death in epilepsy (SUDEP)
Medical Hypotheses, 2009Co-Authors: Fulvio A. Scorza, R. S. De Albuquerque, Ricardo Mario Arida, Beny Schmidt, Antonio-carlos G. De Almeida, Carla A. Scorza, Esper A. CavalheiroAbstract:Summary Epilepsy is the most common serious neurological disorder and approximately 1% of the population worldwide has epilepsy. Moreover, sudden unexpected death in epilepsy (SUDEP) is the most important direct epilepsy-related cause of death. Information concerning risk factors for SUDEP is conflicting, but potential risk factors include: young age, early onset of epilepsy, duration of epilepsy, uncontrolled seizures, seizure frequency, AED number and winter temperatures. Additionally, the cause of SUDEP is still unknown; however, the most commonly suggested mechanisms are cardiac abnormalities during and between seizures. Similarly, sudden death syndrome (SDS) is a disease characterized by an acute death of well-nourished and seeming healthy Gallus Gallus after abrupt and brief flapping of their wings and incidence of SDS these animals has recently increased worldwide. Moreover, the exactly cause of SDS in Gallus Gallus is unknown, but is very probable that cardiac abnormalities play a potential role. Due the similarities between SUDEP and SDS and as Gallus Gallus behavioral manifestation during SDS phenomenon is close of a tonic–clonic seizure, in this paper we suggest that epilepsy could be a new possible causal factor for SDS.
