Background Teleost fishes account for over half of extant vertebrate species. A core question in biology is how genomic changes drive phenotypic diversity that relates to the origin of teleost fishes. Results Here, we used comparative genomic analyses with chromosome assemblies of diverse lineages of vertebrates and reconstructed an ancestral vertebrate genome, which revealed phylogenomic trajectories in vertebrates. We found that the whole-genome-wide chromosome fission/fusions took place in the Monopterus albus lineage after the 3-round whole-genome duplication. Four times of genomic fission/fusions events resulted in the whole genome-wide chromosome fusions in the genomic history of the lineage. In addition, abundant recently evolved new genes for reproduction emerged in the Monopterus albus after separated from medaka. Notably, we described evolutionary trajectories of conserved blocks related to sex determination genes in teleosts. Conclusions These data pave the way for a better understanding of genomic evolution in extant teleosts.Organ homeostasis is essential for organ physiology and disease prevention. In adult vertebrates, the intestinal epithelium is maintained through constant cell proliferation in the crypt and apoptosis of differentiated epithelial cells, mainly at the tip of the villus. Based on studies with altered cell proliferation and tissue damage in the adult mouse intestine, we hypothesize that there is a communication between cell proliferation in the crypt and cell death on the villus, likely via cell-cell and cell-ECM (extracellular matrix) interactions, to coordinate the rate of cell proliferation and death, thus ensuring epithelial homeostasis.Post-operative neurocognitive disorders are becoming well-documented conditions, with their pathogenesis remaining unclear. Vitamin C is a molecule that has recently demonstrated both a potential link with cognitive function and a significant post-operative decline. Here, we present a case study of a 72-year-old male who underwent total knee replacement surgery. The patient demonstrated a substantial decline in plasma vitamin C concentrations, indicative of a severe deficiency, during the first post-operative week (post-operative Days 3 and 7). Similarly, at these time points, a number of validated paper and pen tests revealed a substantial decline in cognition on tasks relating to total recall, delayed recall, motor speed, recognition and motor speed, with no signs of delirium. These results provide the justification for larger, cohort studies to determine whether post-operative plasma vitamin C depletions could contribute to cognitive deficits post-operatively.Foreign body ingestion is a common condition in clinical practice, thankfully most of the cases do not require any surgery as most foreign bodies can pass through the bowel without injuring it. this website Treatment depends on the size and kind of foreign bodies. When complications arise, patients may require urgent medical attention. Self-harm by sharp foreign body ingestion is a rare event that must always be promptly treated and should always be prevented. Psychiatric patients and inmates are the most affected population. A high index of suspicion is required to treat this rare condition, which may be preventable if there is adequate mental and medical therapy along with close monitoring and family support. We present the case of a 31-year-old psychiatric patient. After prompt treatment, two razor blades were surgically removed from her intestines. She fully recovered and is doing well on follow-up controls.Mild- to moderate-sized lip defects that affect one- to two-thirds of the total lip length often require that utilization of local soft tissue rearrangement in order to re-establish lip anatomy, function and esthetics. The use of local flaps in lip reconstruction often follows oncologic resection of common skin malignancies including basal cell carcinoma and squamous cell carcinoma. When considering the types of flaps to use for lip defects of one- to two-third total length, a variety of flaps designs have been described, each with its benefits in drawbacks. In this article, we reintroduce the use and value of the bilateral mucomyocutaneous ‘bandoneon’ flaps for lower lip reconstruction in two of our patients. When compared with other flap designs, it can be used as a single-stage procedure with a very good esthetic outcome, minimal to no microstomia and preservation of lip competence and sensory function.Angiomyofibroblastoma is a rare mesenchymal benign tumor that frequently occurs in young- to middle-aged women, arising from the genital tract. There are many overlapping radiological and immunohistochemical features with other stromal cell lesions, making the diagnosis difficult. We report here a case of a 29-year-old woman admitted for a pelvic mass, in whom, the histopathological and immunohistochemical studies led to the diagnosis of angiomyofibroblastoma.Genetic diversity defines the evolutionary potential of a species, yet mounting evidence suggests that epigenetic diversity could also contribute to adaptation. Elucidating the complex interplay between genetic and epigenetic variation in wild populations remains a challenge for evolutionary biologists, and the intriguing possibility that epigenetic diversity could compensate for the loss of genetic diversity is one aspect that remains basically unexplored in wild plants. This hypothesis is addressed in this paper by comparing the extent and patterns of genetic and epigenetic diversity of phylogenetically closely related but ecologically disparate species. Seven pairs of congeneric species from Cazorla mountains in south-eastern Spain were studied, each pair consisting of one endemic, restricted-range species associated to stressful environments, and one widespread species occupying more favourable habitats. The prediction was tested that endemic species should have lower genetic diversity due to population friation as a source of phenotypic diversity before a realistic understanding of the evolutionary relevance of epigenetic phenomena in plant adaptation can be achieved.
