Interspecific Comparison of Orthologous Short Interspersed Elements Loci Using Whole-Genome Data.

The polymorphism of SINE-containing loci reflects the evolutionary processes that occurred both during the period before the divergence of the taxa and after it. Orthologous loci containing SINE in two or more genomes indicate the relatedness of the taxa, while different copies may have a specific set of mutations and degree of difference. Polymorphic insertion can be interpreted with a high degree of confidence as a shared derived character in the phylogenetic reconstruction of the history of the taxon.

Do kids with forearm fractures need opioids at discharge from the emergency department? Analgesic prescribing and pain control following closed reduction of pediatric forearm fractures.

Objective: The purpose of this 2-part study is to determine opioid prescribing patterns and opioid use and pain control after discharge following closed reduction of pediatric forearm fractures.

Methods: A retrospective study was conducted from December 2016 to January 2018 at a level 1 trauma center to determine opioid prescribing habits for patients 1-17 years old with forearm fractures treated with closed reduction. A prospective study was then conducted from August 2019 to October 2020 to determine pain control and opioid use after discharge.

Early Total Hip Arthroplasty is a Cost-Effective Treatment for Severe Radiographic Slipped Capital Femoral Epiphysis Over an Individual's Lifetime.

Background: Slipped capital femoral epiphysis (SCFE) causes degenerative changes warranting total hip arthroplasty (THA) in approximately 50% of patients by age 60 years. For severe SCFE, a reorienting intertrochanteric osteotomy (ITO) following in situ pinning (ISP) can decrease impingement with hip flexion, but by altering proximal femoral geometry, complicates subsequent conversion THA. We hypothesized that increasing implant survivorship would affect the most cost-effective treatment strategy (ISP followed by ITO [ISP + ITO] with later THA versus ISP alone [ISPa] with earlier THA) over a patient's lifetime.

The mixed liver and kidney transcriptome dataset of Darevskia valentini rock lizard.

Objectives: This study is performed in the frame of a bigger study dedicated to genomics and transcriptomics of parthenogenesis in vertebrates. Among vertebrates, obligate parthenogenesis was first described in the lizards of the genus Darevskia. In this genus, all found parthenogenetic species originated via interspecific hybridization.

First Genome of Rock Lizard Involved in Formation of Several Parthenogenetic Species.

The extant reptiles are one of the most diverse clades among terrestrial vertebrates and one of a few groups with instances of parthenogenesis. Due to the hybrid origin of parthenogenetic species, reference genomes of the parental species as well as of the parthenogenetic progeny are indispensable to explore the genetic foundations of parthenogenetic reproduction. Here, we report on the first genome assembly of rock lizard , a paternal species for several parthenogenetic lineages.

De novo transcriptome assembly and annotation of parthenogenetic lizard and its parental ancestors and .

rock lizards include 29 sexual and seven parthenogenetic species of hybrid origin distributed in the Caucasus. All seven parthenogenetic species of the genus were formed as a result of interspecific hybridization of only four sexual species. It remains unknown what are the main advantages of interspecific hybridization along with switching on parthenogenetic reproduction in evolution of reptiles.

Recurrent Hemarthrosis following Resections of Benign Bone Tumors: A Case Report of Two Pediatric Cases.

. Two pediatric patients presenting with benign bone tumors of the distal femur at the level of the suprapatellar fat pad developed late onset recurrent knee hemarthrosis following surgical treatment of the lesions. A sinus tract from the intramedullary bone to the knee capsule was discovered in both patients during surgical exploration.

Principles of Amputation Surgery, Prosthetics, and Rehabilitation in Children.

Pediatric patients may benefit from extremity amputations with potential prosthetic fitting when addressing limb deficiencies, trauma, infection, limb ischemia, or other pathologies. The performance of a quality amputation is a fundamental skill to an orthopaedic surgeon, yet avoidance of pitfalls can be elusive in children. The need for surgical precision and sound decision-making is amplified in pediatric amputations, where the skeleton is dynamic and growing, anatomy can be miniscule and (in the case of congenital anomalies) variable.

Pain Control and Medication Use in Children Following Closed Reduction and Percutaneous Pinning of Supracondylar Humerus Fractures: Are We Still Overprescribing Opioids?

Background: The purpose of this 2-part study is to determine opioid prescribing patterns and characterize actual opioid use and postoperative pain control in children following discharge after closed reduction and percutaneous pinning of a supracondylar humerus fracture.

Methods: A retrospective study was conducted from 2014 to 2016 to determine pain medication prescribing patterns at a single level 1 trauma center. Next, a prospective, observational study was conducted from 2017 to 2018 to determine actual pain medication use and pain scores in the acute postoperative period.

Origin, clonal diversity, and evolution of the parthenogenetic lizard Darevskia unisexualis.

Background: The hybridization of female D. raddei and male D. valentini gave rise to the parthenogenetic Caucasian rock lizard Darevskia unisexualis.

Multiple interspecific hybridization and microsatellite mutations provide clonal diversity in the parthenogenetic rock lizard Darevskia armeniaca.

Background: The parthenogenetic Caucasian rock lizard Darevskia armeniaca, like most other parthenogenetic vertebrate species, originated through interspecific hybridization between the closely related sexual Darevskia mixta and Darevskia valentini. Darevskia armeniaca was shown to consist of one widespread allozyme clone and a few rare ones, but notwithstanding the origin of clonal diversity remains unclear. We conduct genomic analysis of D.

MOLECULAR GENETIC CHARACTERISTICS OF ALLELE VARIANTS OF MICROSATELLITE LOCI DU281, DU215, AND DU323 IN THE PARTHENOGENETIC LIZARDS DAREVSKIA ROSTOMBEKOVI (FAMILY LACERTIDAE) .

One of the main questions-in the study of the unisexual (parthenogenetic) species of vertebrates is the determination of their genetic diversity. Nuclear and mitochondrial genetic markers can be used for this purpose. One of the most effective genetic markers is the microsatellite DNA, which mutates at a high rate.

[Molecular structure of allelic variants of microsatellite loci Du281 and Du47 in unisexual and bisexual lizard species of the genus Darevskia].

Experimental data on the molecular structure and variability of microsatellite loci in unisexual and bisexual lizard species of the genus Darevskia were analyzed.
