Applied anatomy and clinical significance of the maxillofacial and mandibular regions of the barking deer (Muntiacus muntjak) and sambar deer (Rusa unicolor)

Background: There is no previously reported information on the applied anatomy and clinical significance of the maxillofacial and mandibular regions of the barking deer and sambar deer. Materials and methods: Therefore, the present study was designed to provide some important clinical landmarks related to tracking of the infraorbital, mental and mandibular nerves with its clinical implications in regional anaesthesia in both the species. Results: In the present study, the distance between the most lateral bulging of the facial tuberosity to the infraorbital foramen and from the latter to the root of the alveolar tooth directly ventral to it was found to be 2.65 ± 0.01 cm and 0.90 ± ± 0.02 cm in males; 2.75 ± 0.01 cm, 1.11 ± 0.01 cm in females of barking deer and 4.57 ± 0.01 cm and 1.83 ± 0.02 cm in males; 4.52 ± 0.02 cm and 1.76 ± 0.02 cm in females of sambar deer. The infraorbital foramen was small, elliptical and was located at the level of first superior premolar teeth in barking deer and sambar deer. The facial tuberosity was located above the third superior premolar teeth in the barking deer but was located at the level of the first superior molar teeth in sambar deer. The distance between the lateral alveolar root of the third inferior incisor tooth to the mental foramen was 2.84 ± 0.01 cm in males, 2.78 ± 0.01 cm in females of barking deer and 3.04 ± 0.02 cm in males, 2.96 ± 0.01 cm in females of sambar deer which is an important landmark for achieving the location of the mental foramen nerve for the regional nerve block in both the species. The mandible of both the species showed oval-shaped mental foramen with unossified mandibular symphysis. Conclusions: The present study revealed that most of the parameters showed a statistically significant difference between the sexes in barking deer and sambar deer; however, from the practical point of view, these differences were meager. The results were discussed with regard to their clinical applications in various regional anaesthesia performed in maxillofacial and mandibular regions of both the species

Not AvailableYak (Bos grunniens) is a unique bovine species and considered as lifeline of highlanders. The male subfertility in yak is a matter of concern that causes huge economic loses. The spermatogenesis and male reproduction machinery are critically governed by Y-linked genes which tend to acquire necessary information in the course of evolution. The Y-linked fertility genes are present in multiple copies with testis-limited expression. To understand this novel complexity, 12 male-specific region of Y chromosome (MSY) genes have been studied in the yak. Targeted genes are amplified in male and female genomic DNA and confirmed the male derived specificity. Moreover, testis and sperm-specific expressions of MSY genes are distinct among different tissues. The quantitative polymerase chain reaction results validate the expression pattern of these genes in various tissues with predominant expression intestis and sperm. The sequencing of resultant yak MSY genes gives significant result and shows similarity with cattle (Bos indicus), but few nucleotide mismatches define the proposition of infertile male in the F1 hybrid of cattle and yak. The identified MSY genes can be used to establish male-specific characteristics and to differentiate male and female yak genotypically. Further, these genes may act as valuable resources to understand the capacity of spermatogenesis, embryogenesis, cellular growth, azoospermia and malesubfertility in the yak.Not Availabl
