The hog deer (Axis porcinus) is threatened by habitat alteration, fragmentation, and poaching, which have led to a drastic decline of its wild population. Two subspecies of A. porcinus have been described from its distribution range. A. p. porcinus is reported to occur from Pakistan along the Himalayan foothills through Nepal, India and Myanmar, and A. p. annamiticus is found in Thailand, Indo-China, Laos, Cambodia, and Vietnam. However, the current distribution range of A. p. annamiticus is still unclear. We used the partial control region (CR) of mitochondrial DNA (mtDNA) and seven microsatellite loci to investigate the intra-species structure, differentiation, and demographic history of hog deer populations from three landscapes, the Terai Arc, Northeast, and Indo-Burma (Keibul Lamjao National Park (KLNP), Manipur, India) landscapes. We also carried out divergence time estimation using the complete mitogenome. The level of variation was ~4%, and the time of divergence of the KLNP population and the other Indian populations was about 0.22 Mya, i.e., during the last glaciation periods of the Late Pleistocene/Early Holocene. The KLNP haplotypes of the control region were shared with the Southeast Asian subspecies, A. p. annamiticus. The results of the investigations of the microsatellite loci supported the mtDNA results unambiguously. Two genetically distinct lineages are found in India: one is found from the Terai Arc to Assam (A. p. porcinus) and the other in Manipur (A. p. annamiticus). The genetic diversity in KLNP was low and exhibited a higher degree of genetic differentiation compared with major Indian populations. The Bayesian skyline plots indicated that after a long phase of historic demographic stability, the populations of both the lineages of hog deer suffered pronounced declines during the period from ~800 years BP to 5000 years BP. In summary, our finding provided evidence that the KLNP population is probably a prime, isolated and sustaining stock of A. p. annamiticus and should be managed as evolutionarily significant units (ESUs).

The endangered Kashmir musk deer (Moschus cupreus) is native to the high altitudinal 2 region of the Himalayas. In this study, we sequenced, annotated and characterized the 2 complete mitogenome of M. cupreus to gain insight into the molecular phylogeny and 2 evolution of musk deer. The mitogenome of M. cupreus, which is 16,354 bp long comprised 2 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), two ribosomal RNA genes 2 (rRNAs) and non-coding control region. The M. cupreus mitogenome composition was 2 highly A+T biased 68.42%, and exhibited a positive AT skew (0.082) and negative GC skew 2 (0.307). The phylogenetic analysis suggested that KMD is the most primitive extant species 2 in the genus Moschus whereas Alpine musk deer (M. chrysogaster) and Himalayan musk 2 deer (M. leucogaster) are closely related. This result confirmed the placement of M. cupreus 2 within the monotypic family Moschidae of musk deer. This study provides a better 3 understanding of lineage identification and musk deer evolution for further research.

Objective:The aim of this study was to determine any relationship, if exists, between the patient's mental attitude with age, sex, or educational qualification.Methods:A total of 200 patients who attended the outpatient department during a span of 1 year, for the fabrication of new complete dentures, were chosen for the study. After completing a routine case history and examination, a questionnaire was filled by the clinician as answered by the patient. Participants were evaluated and categorized based on the questionnaire and clinical experience during treatment according to a predefined classification of determining mental attitudes. Outcomes from the survey were correlated with participant gender, age, and educational status.Results:The male to female ratio was 83:117, out of the 200 enrolled participants. The results from the questionnaire showed that females were found to be more exacting (P = 0.007) in nature, while males, on the other hand, revealed more indifferent attitude (P = 0.02); both differences being statistically significant. Of the three age group categories: Participants in the age group of 45–54 years revealed a significant inclination toward an exacting attitude when compared with other age groups (P < 0.001). In regards to educational status, an illiterate or minimally educated group significantly outnumbered the college graduates in the indifferent attitude group (P < 0.001).Conclusions:Within the limitations of this study, it could be said that the mental attitudes of patients could vary according to gender, age, and educational status, which could affect patient cooperation and satisfaction with oral rehabilitation, eventually manipulating the overall success of the treatment rendered.

BackgroundThe mitochondrial DNA (mtDNA) control region is extensively used in the phylogeography of species. We examined sequence variations in the mtDNA control region of sambar (Rusa unicolor) populations from the South, Central and North India.ResultsMost of the samples collected from the south India exhibited a 40 bp insertion in the mtDNA control region. This insertion was not observed in the North and Central Indian populations.ConclusionThis study provided a potential marker for molecular screening and identification of sambar populations in the form of a distinct 40 bp insertion. Some populations in South India did not exhibit this insertion. It indicates that there could be an ecological barrier that might be preventing the expansion of insertion-positive sambar population.
