Reproducibility of dynamic balance and anterior tibiofibular gap measurements in men and women: A menstrual cycle-based longitudinal study.

Background: The reproducibility of dynamic balance is an essential component of athletic performance and injury prevention, although it is affected by sex differences. This study aimed to confirm the reproducibility of repeated dynamic balance measurements and ultrasonography assessments of the anterior tibiofibular gap that may contribute to changes in dynamic balance for each sex.

Methods: This was a longitudinal study involving 48 feet, with 12 men and 12 women.

The vertical mobility of the first tarsometatarsal joint during demi-plié with forced turnout in ballet dancers.

The forced turnout has a perceived risk of development of hallux valgus (HV) in ballet dancers. We determined how the forced turnout affects the sagittal mobility of the first tarsometatarsal (TMT) joint, which is one of the pathogenic factors of HV development. Seventeen female ballet dancers (body mass index: 18.

TP53 Variant in the Blood of a Patient with Gastric Cancer Undergoing Tumor Profiling Tests Diagnosed as Clonal Hematopoiesis.

BACKGROUND Clonal hematopoiesis is the production of a specific single clonal type of cell in the blood and is often found in cancer genomic profiling tests. When the clone carries a pathogenic variant, it may be important to differentiate between somatic or germline origin. The variant in the blood that has a lower minor allele frequency could reflect heterozygous germline origin, somatic mosaicism, and clonal hematopoiesis.

Lysine-specific demethylase 1 as a corepressor of mineralocorticoid receptor.

Mineralocorticoid receptor (MR) and its ligand aldosterone play a central role in controlling blood pressure by promoting sodium reabsorption in the kidney. Coregulators are recruited to regulate the activation of steroid hormone receptors. In our previous study, we identified several new candidates for MR coregulators through liquid chromatography-tandem mass spectrometry analysis using a biochemical approach.

Cardiac tamponade due to primary malignant pericardial mesothelioma diagnosed with surgical pericardial resection.

Primary malignant pericardial mesothelioma is an extremely rare disease. Malignant disease of the pericardium is an infrequent cause of cardiac tamponade. Hence, cardiac tamponade in the context of primary malignant mesothelioma of the pericardium is an uncommon clinical scenario.

Late-onset cerebral arteriopathy in a patient with incontinentia pigmenti.

Background: Incontinentia pigmenti (IP) is an X-linked neurocutaneous disorder that can present with cerebral arteriopathy during early infancy. However, no previous reports have demonstrated arteriopathic manifestations during postinfantile childhood in patients with IP.

Patient Description: We describe a case of IP in a 2-year-old girl who developed encephalopathic manifestations associated with influenza A infection.

Molecular analysis of low-level mosaicism of the IKBKG mutation using the X Chromosome Inactivation pattern in Incontinentia Pigmenti.

Background: Incontinentia pigmenti (IP) is a rare X-linked disorder affecting the skin and other ectodermal tissues that is caused by mutation of the IKBKG/NEMO gene. Previous studies have reported that the overall mutation detection rate in IP is ~75%. We hypothesized that a low-level mosaicism existed in the remaining cases.

Analysis of the Origin of Double Mosaic Aneuploidy in Two Cases.

We present 2 cases of double mosaic aneuploidy harboring 2 or more different aneuploid cell lines, but no line with a normal chromosome constitution. One of these cases presented mosaicism of sex chromosome aneuploid cell lines (47,XXX/45,X) along with another line containing an autosomal trisomy (47,XX,+8), while the other case showed mosaicism of 2 different autosomal trisomy cell lines (47,XY,+5 and 47,XY,+8). To elucidate the mechanisms underlying these mosaicisms, we conducted molecular cytogenetic analyses.

A female patient with retinoblastoma and severe intellectual disability carrying an X;13 balanced translocation without rearrangement in the RB1 gene: a case report.

Background: Female carriers of a balanced X; autosome translocation generally undergo selective inactivation of the normal X chromosome. This is because inactivation of critical genes within the autosomal region of the derivative translocation chromosome would compromise cellular function. We here report a female patient with bilateral retinoblastoma and a severe intellectual disability who carries a reciprocal X-autosomal translocation.

Carbon Materials with Zigzag and Armchair Edges.

Carbon materials such as graphene and graphene nanoribbon with zigzag and armchair edges have attracted much attention because of various applications such as electronics, batteries, adsorbents, and catalyst supports. Preparation of carbon materials with different edge structures at a large scale is essential for the future of carbon materials, but it is generally difficult and expensive because of the necessity of organic synthesis on metal substrates. This work demonstrated a simple preparation method of carbon materials with zigzag and armchair edges with/without nonmetallic silica supports from aromatic compounds such as tetracene with zigzag edges and chrysene with armchair edges and also determined the edge structures in detail by three types of analyses such as (1) reactive molecular dynamic simulation with a reactive force field, (2) Raman and infrared (IR) spectra combined with calculation of spectra, and (3) reactivity analyzed by oxidative gasification using thermogravimetric analysis.

Two siblings with 11qter deletion syndrome that had been rescued in their mother by uniparental disomy.

Jacobsen syndrome refers to a congenital anomaly caused by deletion at 11q23.3-qter. We here describe two siblings with the same 11q23.

Paramecium caudatum acquires heat-shock resistance in ciliary movement by infection with the endonuclear symbiotic bacterium Holospora obtusa.

Holospora obtusa is a macronucleus-specific bacterium of the ciliate Paramecium caudatum. Three types of P. caudatum cells (H.

Transplantation of cardiotrophin-1-expressing myoblasts to the left ventricular wall alleviates the transition from compensatory hypertrophy to congestive heart failure in Dahl salt-sensitive hypertensive rats.

Objectives: We investigated whether autologous transplantation of skeletal myoblasts (MB) transferred with cardiotrophin-1 (CT-1) gene could retard the transition to heart failure (HF) in Dahl salt-sensitive (DS) hypertensive rats.

Background: Although MB is a therapeutic candidate for chronic HF, little is known about the efficiency of this strategy when applied in nonischemic HF. Cardiotrophin-1 has potent hypertrophic and survival effects on cardiac myocytes.

Glycogen synthase kinase-3beta is involved in the process of myocardial hypertrophy stimulated by insulin-like growth factor-1.

Background: Glycogen synthase kinase-3 beta (GSK-3beta) is involved in many cellular processes, such as metabolism, apoptosis, differentiation and proliferation. Insulin-like growth factor-1 (IGF-1), which is well known to have a hypertrophic effect on cardiomyocytes, inactivates (phosphorylates) GSK-3beta in some cell types. The role of GSK-3beta in cardiomyocytes as a negative regulator of cardiac hypertrophy has been recently reported and the present study investigated the role of GSK-3beta in the cardiac hypertrophy of cultivated neonatal rat cardiomyocytes induced by IGF-1.

Cardiac myocytes are recruited by bone marrow-derived cells in intact murine heart.

It is generally believed that the cardiac myocytes withdraw from the cell cycle shortly after birth and thereafter any loss of myocardial tissue cannot be repaired. However, recent reports indicate that cardiac myocytes can be regenerated by stem cells derived from bone marrow in the damaged hearts. In this study, we investigated whether bone marrow-derived cells can differentiate into cardiac myocytes in the intact hearts.

Ral GDP dissociation stimulator and Ral GTPase are involved in myocardial hypertrophy.

Ras-related GTPase (Ral) is converted to the GTP-bound form by Ral GDP dissociation stimulator (Ral-GDS), a putative effector protein of Ras. Although a number of studies indicate that Ras induces cardiac hypertrophy, the functional role of Ral-GDS/Ral signaling pathway is as yet unknown in cardiac myocytes. We investigated the role of the Ral-GDS/Ral pathway in cardiac hypertrophy.
