Expression of Vascular and Tissue Repair Factors in Laryngeal Granulomas.

Voice abuse, chronic cough, laryngeal surgery, and tracheal intubation may lead to injury and subsequent repair/remodeling in the vocal fold mucosa. Periostin is known to be involved in airway remodeling and is also associated with various otolaryngological diseases. D-β-aspartic acid is the major isomer of D-aspartic acid found in tissues of elderly individuals.

Preparation and Application of Decanoic Acid/Arginine Hydrogels to a Transdermal Formulation.

We prepared a supramolecular hydrogel composed of decanoic acid and arginine (C10/Arg gel) and evaluated its application to a transdermal formulation. C10/Arg gel adjusted to pH 7 with 1 M NaOH aq or 1 M HCl aq provided a translucent hydrogel with a lamellar liquid crystal structure in the concentration region of decanoic acid ≥12% and arginine ≤9%. Rheological measurements showed that C10/Arg gel is a viscoelastic material with both solid and liquid properties, with elasticity being dominant over viscosity in the low shear stress region.

Impact of the novel coronavirus infection on pediatric surgery: an analysis of data from the National Clinical Database.

Purpose: The coronavirus disease 2019 (COVID-19) pandemic limited the delivery of medical resources. Although surgeries are triaged according to disease severity and urgency, a delay in diagnosis and surgery can be detrimental. We conducted this study to analyze data on the impact of the COVID-19 pandemic on pediatric surgery for different diseases or disorders.

Synthesis, Structure, and Redox and Optical Properties of 5,10,15,20-Tetraaryl-5-azaporphyrinium Salts.

The fundamental properties of azaporphyrins can be modulated over a wide range by changing the number of meso-nitrogen atoms. Reported herein are the first examples of 5,10,15,20-tetraaryl-5-azaporphyrinium (MTAMAP) salts, which were prepared via metal-templated cyclization of the corresponding zinc(II) and copper(II) complexes of 10-aryl-1-chloro-19-benzoyl-5,15-dimesityl-10-azabiladiene-ac. The inclusion of one meso-nitrogen atom in the 5,10,15,20-tetraarylporphyrin skeleton considerably changes the redox and optical properties as well as the degree of aromaticity of the porphyrin ring.

A Case of Uterine Tumor Resembling Ovarian Sex Cord Tumor With Prominent Myxoid Features.

Uterine tumor resembling ovarian sex cord tumor (UTROSCT) is a rare tumor with low malignant potential that commonly occurs in middle age. Although more than 100 cases have been reported to date, myxoid morphology is not well documented. Here, we present a 75-yr-old woman with abnormal vaginal bleeding, with an 8-cm mass in the uterine corpus detected by irregular, high-intensity signaling on T2-weighted imaging.

Objective/hypothesis: Middle ear cholesteatoma is characterized by abnormal growth of the keratinizing squamous epithelium of the temporal bone. d--aspartic acid is the major isomer of d-aspartic acid found in elderly tissue. We assessed the immunoreactivity to k--aspartic acid of congenital and acquired middle ear cholesteatomas.

Expression and clinicopathological significance of glucocorticoid receptor, SGK1, and NDRG1 in hormone-naïve prostate carcinoma.

Glucocorticoid receptor (GR) has been implicated in prostate carcinoma growth and progression. Glucocorticoid receptor beta (GRβ) acts as an inhibitor of GR; however, its function is not well understood. Serum- and glucocorticoid-regulated kinase 1 (SGK1) is a GR-responsive gene that phosphorylates N-myc downstream-regulated gene 1 (NDRG1) and is involved in cancer growth and invasion.

Expression of Periostin in Vocal Fold Polyps.

Long-term voice abuse or sudden vocal fold microvascular disruption may lead to injury and subsequent repair/remodeling in the vocal fold mucosa. Periostin is known to be involved in airway remodeling and also in various otolaryngological diseases. The aim of this article was to investigate the expression and the role of periostin in the formation of vocal fold polyps.

Murine Double Minute 2 Antagonist Nutlin-3 Enhanced Chemosensitivity in Esophageal Squamous Cell Carcinoma.

Background/aim: Murine double minute 2 (MDM2) is well known to inhibit p53 function and its over-expression is associated with poor prognosis in several human malignancies. Nutlin-3, a small-molecule inhibitor of MDM2, exerts antitumor effects on various solid tumors harboring wild-type p53. We aimed to clarify its effects on esophageal cancer.

Machine Learning Algorithms: Prediction and Feature Selection for Clinical Refracture after Surgically Treated Fragility Fracture.

Background: The number of patients with fragility fracture has been increasing. Although the increasing number of patients with fragility fracture increased the rate of fracture (refracture), the causes of refracture are multifactorial, and its predictors are still not clarified. In this issue, we collected a registry-based longitudinal dataset that contained more than 7000 patients with fragility fractures treated surgically to detect potential predictors for clinical refracture.

Aberrant expression of MYD88 via RNA-controlling CNOT4 and EXOSC3 in colonic mucosa impacts generation of colonic cancer.

In 2020, the worldwide incidence and mortality of colorectal cancer (CRC) were third and second, respectively. As the 5-y survival rate is low when CRC is diagnosed at an advanced stage, a reliable method to predict CRC susceptibility is important for preventing the onset and development and improving the prognosis of CRC. Therefore, we focused on the normal colonic mucosa to investigate changes in gene expression that may induce subsequent genetic alterations that induce malignant transformation.

Clinicopathological Significance of Estrogen Receptor and Estrogen Synthesizing/Metabolizing Enzymes in Urothelial Carcinoma of Urinary Bladder.

Sex-specific differences in the incidence of urinary bladder carcinomas are well known, and the possible involvement of sex steroids has been proposed. We previously reported the association of the loss of androgen receptors and androgen-producing enzymes with tumor progression of urinary bladder cancer patients. Clinically, the selective estrogen receptor modulators (SERMs) were reported to suppress the progression of these tumors but the status of estrogen receptors (ERs) has not been well studied in patients with bladder urinary cancer.

Endoscopic Treatment of Sinonasal Leiomyosarcoma: A Case Report in Light of the Literature.

A 49-year-old Japanese man presented with a rare case of sinonasal leiomyosarcoma with left nasal bleeding for 12 months. He had no history of irradiation or malignancies, including retinoblastoma. Preoperative histological examination suggested vascular leiomyoma.

Loss of H3K27 trimethylation is frequent in IDH1-R132H but not in non-canonical IDH1/2 mutated and 1p/19q codeleted oligodendroglioma: a Japanese cohort study.

Oligodendrogliomas are defined by mutation in isocitrate dehydrogenase (NADP(+)) (IDH)1/2 genes and chromosome 1p/19q codeletion. World Health Organisation diagnosis endorses testing for 1p/19q codeletion to distinguish IDH mutant (Mut) oligodendrogliomas from astrocytomas because these gliomas require different treatments and they have different outcomes. Several methods have been used to identify 1p/19q status; however, these techniques are not routinely available and require substantial infrastructure investment.

Melatonin ameliorates oxidative stress and DNA damage of rats subjected to a chemically induced chronic model of Maple Syrup Urine Disease.

Maple Syrup Urine Disease (MSUD) is an inborn error of metabolism caused by a deficiency of branched α-ketoacid dehydrogenase complex (BCKDC) activity. Branched-chain amino acids (BCAA) accumulation is, at least in part, responsible for neurological disturbances characteristic of this metabolic disorder. Experimental studies demonstrated that high levels of BCAA induce brain oxidative stress.

Endoscopic Treatment of Sinonasal Glomangiopericytoma: A Case Report in Light of the Literature.

A 71-year-old Japanese male patient presented with a rare case of Glomangiopericytoma (GPC) of the left nasal with obstruction. Complete resection with endoscopic surgery was performed. Immunohistochemical staining for smooth muscle actin, β catenin, cyclin D1, vimentin, and factor 13 were helpful in establishing a definitive diagnosis.

Evaluation of the mindfulness-augmented "Trampoline" programme - a German prevention programme for children from substance-involved families tested in a cluster-randomised trial.

Background: Children of substance-abusing parents are at a substantial risk of developing substance-use and other mental disorders. Children involved in substance abuse - not diagnosed with substance-use problems but integrated in psychiatric treatment or youth welfare services - constitute a particular high-risk group that is in need of substance use prevention. Emerging evidence indicates that self-regulatory determinants of substance use and other mental disorders, particularly stress reactivity, are modifiable by mindfulness-based interventions, such as mindfulness-based stress reduction.
