Postoperative outcome of screw fixation with autogenous bone grafting for the management of hallux sesamoid fracture nonunion.

Introduction: Although sesamoid-preserving procedures have been attempted to complement sesamoidectomy for hallux sesamoid fracture nonunion, few reports document the results. Accordingly, the objective of this study was to review the outcomes of patients with hallux sesamoid fracture nonunion who underwent screw fixation with autogenous bone grafting.

Materials And Methods: Medical records of patients who underwent surgery between January 2013 and September 2022 were reviewed.

Threshold of Quantitative Cytomegalovirus DNA PCR for Preemptive Treatment in Pediatric Hematopoietic Stem Cell Transplant Recipients.

Background: Consensus cytomegalovirus (CMV) DNA viral load thresholds for intervention in hematopoietic stem cell transplant (HSCT) recipients have not been established, especially in children. This study aimed at obtaining viral load thresholds of CMV DNA to guide preemptive management in pediatric HSCT recipients.

Materials And Methods: A total of 465 blood samples from 177 children who received HSCT between 2015 and 2019 were included in a single center in Korea.

Concentration Gradient Induced Delithiation Failure of MoO for Li-Ion Batteries.

Electric vehicle manufacturers worldwide are demanding superior lithium-ion batteries, with high energy and power densities, compared to gasoline engines. Although conversion-type metal oxides are promising candidates for high-capacity anodes, low initial Coulombic efficiency (ICE) and poor capacity retention have hindered research on their applications. In this study, the ICE of conversion-type MoO is investigated, with a particular focus on the delithiation failure.

High-Ni cathode material improved with Zr for stable cycling of Li-ion rechargeable batteries.

The Zr solvent solution method, which allows primary and secondary particles of LiNiCoMnO (NCM) to be uniformly doped with Zr and simultaneously to be coated with an LiZrO layer, is introduced in this paper. For Zr doped NCM, which is formed using the Zr solvent solution method (L-NCM), most of the pinholes inside the precursor disappear owing to the diffusion of the Zr dopant solution compared with Zr-doped NCM, which is formed using the dry solid mixing method from the (NiCoMn)(OH) precursor and the Zr source (S-NCM), and LiZrO is formed at the pinhole sites. The mechanical strength of the powder is enhanced by the removal of the pinholes by the formation of LiZrO resulting from diffusion of the solvent during the mixing process, which provides protection from cracking.

The preliminary study for three-dimensional alveolar bone morphologic characteristics for alveolar bone restoration.

Background: The concept of the ideal morphology for the alveolar bone form is an important element to reconstruct or restore the in maximizing esthetic profile and functional alveolar bone restoration. The purpose of this preliminary study is to evaluate the normal alveolar bone structure to provide the standard reference and guide template for use in diagnosing for implant placement, determining the correct amount of bone augmentation in actual clinical practice and producing prostheses based on three-dimensional imaging assessment of alveolar bone.

Methods: This study was included 11 men and 11 women (average age, 22.

S6K1 controls epigenetic plasticity for the expression of pancreatic α/β cell marker genes.

The failure of insulin production by pancreatic β cells is a common hallmark of type 1 diabetes mellitus (T1DM). Because administration of exogenous insulin is associated with diabetes-derived complications, endogenous α to β cell transition can be an attractive alternative. Although decreased β cell size and hypoinsulinaemia have been observed in S6K1-deficient mice, the molecular mechanism underlying the involvement of S6K1 in the transcriptional regulation of insulin remains elusive.

Estimation of heritability and genetic correlation of body weight gain and growth curve parameters in Korean native chicken.

Objective: This study estimated the genetic parameters for body weight gain and growth curve parameter traits in Korean native chicken (KNC).

Methods: A total of 585 F chickens were used along with 88 of their F birds. Body weights were measured every 2 weeks from hatching to 20 weeks of age to measure weight gain at 2-week intervals.

Chemically Driven Enhancement of Oxygen Reduction Electrocatalysis in Supported Perovskite Oxides.

Perovskite oxides have the capacity to efficiently catalyze the oxygen reduction reaction (ORR), which is of fundamental importance for electrochemical energy conversion. While the perovskite catalysts have been generally utilized with a support, the role of the supports, regarded as inert toward the ORR, has been emphasized mostly in terms of the thermal stability of the catalyst system and as an ancillary transport channel for oxygen ions during the ORR. We demonstrate a novel approach to improving the catalytic activity of perovskite oxides for solid oxide fuel cells by controlling the oxygen-ion conducting oxide supports.

An accurate method for quantifying and analyzing copy number variation in porcine KIT by an oligonucleotide ligation assay.

Background: Aside from single nucleotide polymorphisms, copy number variations (CNVs) are the most important factors in susceptibility to genetic disorders because they affect expression levels of genes. In previous studies, pyrosequencing, mini-sequencing, real-time PCR, invader assays and other techniques have been used to detect CNVs. However, the higher the copy number in a genome, the more difficult it is to resolve the copies, so a more accurate method for measuring CNVs and assigning genotype is needed.

Clinical Significance of the Levels of Serum Cholesterol in Patients with Gastric Cancer.

Purpose: The relationship between serum cholesterol levels and mortality is complex. Serum cholesterol levels correlate positively with coronary artery disease, but some studies have suggested a negative relationship in cancer patients. Because the serum cholesterol levels are one of the most frequently assayed laboratory values, trends in the levels of cholesterol were investigated, in patients with gastric cancer and assumed a possible role in cancer screening.
