A Novel Surgical Solution for Sciatic Hernia: Exploring the Totally Extraperitoneal Approach.

Sciatic hernia, a rare type of pelvic floor hernia, presents significant diagnostic and therapeutic challenges. We report the first totally extraperitoneal (TEP) repair of a sciatic hernia, which was performed in a 63-year-old woman who presented with vomiting and poor dietary intake. Computed tomography revealed a strangulated femoral hernia and an incidental herniation of the sigmoid colon through the right sciatic foramen.

Exploring Molecular Descriptors and Acquisition Functions in Bayesian Optimization for Designing Molecules with Low Hole Reorganization Energy.

Organic semiconductors have been widely studied owing to their potential applications in various devices, such as field-effect transistors, light-emitting diodes, solar cells, and image sensors. However, they have a limitation of significantly lower carrier mobility compared to silicon, which is a widely used inorganic semiconductor. Therefore, to address such limitations, these molecules should be further explored.

High total Joule heat increases the risk of post-endoscopic submucosal dissection electrocoagulation syndrome after colorectal endoscopic submucosal dissection.

Background: We hypothesized that thermal damage accumulation during endoscopic submucosal dissection (ESD) causes the pathogenesis of post-ESD electrocoagulation syndrome (PECS).

Aim: To determine the association between Joule heat and the onset of PECS.

Methods: We performed a retrospective cohort study in patients who underwent colorectal ESD from May 2013 to March 2021 in Japan.

A multicolor and ratiometric fluorescent sensing platform for metal ions based on arene-metal-ion contact.

Despite continuous and active development of fluorescent metal-ion probes, their molecular design for ratiometric detection is restricted by the limited choice of available sensing mechanisms. Here we present a multicolor and ratiometric fluorescent sensing platform for metal ions based on the interaction between the metal ion and the aromatic ring of a fluorophore (arene-metal-ion, AM, coordination). Our molecular design provided the probes possessing a 1,9-bis(2'-pyridyl)-2,5,8-triazanonane as a flexible metal ion binding unit attached to a tricyclic fluorophore.

Fluorescence detection of metabolic activity of the fatty acid beta oxidation pathway in living cells.

Detection of metabolic activity in living cells facilitates the understanding of the cell mechanism. Here, we report a fluorescent probe that can detect fatty acid beta oxidation (FAO) in living cells. This probe is metabolically degraded by the sequential enzyme reactions of FAO and can visualize the FAO activity with turn-on fluorescence.

[Evaluation of Clinical Features and Growth Hormone Deficiency in Short Children Born Small For Gestational Age].

Growth hormone (GH) therapy for short children born small for gestational age (SGA) has been approved in Japan. It is important to evaluate GH secretion ability before the initiation of GH therapy because there are some differences in dose and medical expenses between short children born SGA and GH deficiency (GHD). This study was designed to elucidate the incidence of GHD and to find a useful marker for detecting it in short SGA children.

A Pediatric Case of Graves' Hyperthyroidism with Associated Glucose Intolerance Detected by a Urine Glucose Screening Program at School.

We report here a 13-year-old female with Graves' disease, whose diagnostic clue was glycosuria, which was detected by a urine glucose screening program at school. She had had mild general malaise, and a physical examination revealed a slightly enlarged thyroid gland. Hyperthyroidism (thyroid-stimulating hormone (TSH) < 0.

Reversible ratiometric detection of highly reactive hydropersulfides using a FRET-based dual emission fluorescent probe.

Hydropersulfide (R-SSH) is an important class of reactive sulfur species (RSS) involved in a variety of physiological processes in mammals. A fluorescent probe capable of real-time detection of hydropersulfide levels in living cells would be a versatile tool to elucidate its roles in cell signalling and redox homeostasis. In this paper, we report a ratiometric fluorescent probe for hydropersulfide sensing, based on a fluorescence resonance energy transfer (FRET) mechanism.

Plasma but not serum brain-derived neurotrophic factor concentration is decreased by oral glucose tolerance test-induced hyperglycemia in children.

Background: Little is known regarding the relationships among circulating brain-derived neurotrophic factor (BDNF) levels and glucose or insulin in children and adolescents. The objective of this study was to investigate whether circulating BDNF levels would change during the oral glucose tolerance test (OGTT).

Methods: We performed the OGTT and measured the serial changes in BDNF levels in both plasma and serum.

Sporadic pseudohypoparathyroidism type-1b with asymptomatic hypocalcemia.

Pseudohypoparathyroidism type 1b (PHP-1b) is usually diagnosed on various symptoms of hypocalcemia. Previous studies reported a few cases of autosomal dominant pattern PHP-1b identified on familial analysis with asymptomatic hypocalcemia. Herein we report the case of a 6-year-old male patient with sporadic PHP-1b incidentally detected on preoperative examination.

Differences in the Pulsatile Component of the Skin Hemodynamic Response to Verbal Fluency Tasks in the Forehead and the Fingertip.

Several studies have claimed that hemodynamic signals measured by near-infrared spectroscopy (NIRS) on the forehead exhibit different patterns during a verbal fluency task (VFT) in various psychiatric disorders, whereas many studies have noted that NIRS signals can reflect task-related changes in skin blood flow. If such a task-related skin hemodynamic response is also observed in the fingertip, a simpler biomarker may be developed. Furthermore, determining the difference in the response pattern may provide physiological insights into the condition.

Rational Design of a Ratiometric Fluorescent Probe Based on Arene-Metal-Ion Contact for Endogenous Hydrogen Sulfide Detection in Living Cells.

We report the design and development of a fluorescent Cd(II) ion complex that is capable of the ratiometric detection of H2 S in living cells. This probe exploits the metal-ion-induced emission red shift resulting from direct contact between the aromatic ring of a fluorophore and a metal ion (i.e.

Development of an AND logic-gate-type fluorescent probe for ratiometric imaging of autolysosome in cell autophagy.

The concomitant detection of two biological events facilitates the highly selective and sensitive analysis of specific biological functions. In this article, we report an AND logic-gate-type fluorescent probe that can concurrently sense two biological events in living cells: H2 O2 accumulation and acidification. The probe exhibits a unique fluorescence sensing mechanism, in which a xanthene fluorophore is oxidatively transformed to a xanthone derivative by H2 O2 , thereby resulting in a clear dual-emission change.

Tamoxifen treatment for pubertal gynecomastia in two siblings with partial androgen insensitivity syndrome.

Background: Although tamoxifen has been shown to be fairly safe and effective for idiopathic pubertal gynecomastia, it remains unknown whether it is also beneficial for gynecomastia associated with endocrine disorders. Here, we report the effect of tamoxifen on pubertal gynecomastia in 2 siblings with partial androgen insensitivity syndrome (PAIS).

Case Reports: Cases 1 and 2 presented with persistent pubertal gynecomastia at 13 and 16 years of age, respectively.

Design of ratiometric fluorescent probes based on arene-metal-ion interactions and their application to Cd(II) and hydrogen sulfide imaging in living cells.

Non-coordinative interactions between a metal ion and the aromatic ring of a fluorophore can act as a versatile sensing mechanism for the detection of metal ions with a large emission change of fluorophores. We report the design of fluorescent probes based on arene-metal-ion interactions and their biological applications. This study found that various probes having different fluorophores and metal binding units displayed significant emission redshift upon complexation with metal ions, such as Ag(I), Cd(II), Hg(II), and Pb(II).

An Infantile Case of Transient, Severe Hypercholesterolemia with Normalization after Complete Weaning from Breast-feeding.

A 20-d-old boy was referred to our department because of hyperthyrotropinemia at neonatal mass screening and diagnosed with neonatal transient hyperthyrotropinemia. A follow-up examination when the patient was 5 mo old revealed severe hypercholesterolemia. Familial hypercholesterolemia was first suspected because of the patient's significantly high levels of total and low-density lipoprotein cholesterol.

Influence of skin blood flow on near-infrared spectroscopy signals measured on the forehead during a verbal fluency task.

Brain activity during a verbal fluency task (VFT) has been the target of many functional imaging studies. Most studies using near-infrared spectroscopy (NIRS) have reported major activation in the frontal pole, but those using PET or fMRI have not. This led us to hypothesize that changes in the NIRS signals measured in the forehead during VFT were due to changes in skin blood flow.

[Prevalence of 'obesity disease' and 'metabolic syndrome' in obese pediatric outpatients at the University Hospital of Occupational and Environmental Health, Japan].

'Obesity Disease for Japanese Children' was defined in 2002, and very recently 'Metabolic Syndrome (MS) for Japanese Children' was also defined. We therefore aimed to determine the prevalence of these two among the obese pediatric outpatients at our university hospital. The subjects were 97 children, 58 boys and 39 girls, ranging in age from 5 to 15 years.

Plasma visfatin concentration as a surrogate marker for visceral fat accumulation in obese children.

Objective: This study was designed to elucidate whether the plasma visfatin level reflects visceral or subcutaneous fat accumulation and metabolic derangement in obese children.

Methods And Procedures: Fifty-six obese Japanese children, including 37 boys and 19 girls were enrolled in the study. The age of the subjects ranged from 5 to 15 (10.

N-acetylcysteine inhibits induction of nitric oxide synthase in 3T3-L1 adipocytes.

The present study was designed to determine whether N-acetylcysteine (NAC), a potent antioxidant, modulates nitric oxide (NO) production stimulated by lipopolysaccharide (LPS) and tumor necrosis factor-alpha (TNF-alpha) in adipocytes. Stimulation by the combination of 5 microg/ml of LPS and 100 ng/ml of TNF-alpha (LT) significantly enhanced NO production in 3T3-L1 adipocytes. Preincubation of the cells with NAC (5-20 mM) for 24 h suppressed the increased NO production in a dose-dependent manner.

Hydroxymethylglutaryl--CoA reductase inhibitor inhibits induction of nitric oxide synthase in 3T3--L1 preadipocytes.

Preadipocytes are considered to play a role in adipose tissue inflammation in obesity. The purpose of this study was to determine whether hydroxymethylglutaryl-CoA reductase inhibitor (statin) modulates the nitric oxide (NO) production via inducible NO synthase (iNOS) in preadipocytes. Undifferentiated 3T3-L1 cells, a model of preadipocytes, significantly produced NO by the treatment with the combination of lipopolysaccharide (L), tumor necrosis factor-alpha (T) and interferon-gamma (I).

Postnatal development of galanin-like peptide mRNA expression in rat hypothalamus.

We examined the developmental change of GALP mRNA in male and female rat hypothalamus during postnatal day 1 to 60, using in situ hybridization histochemistry. Neuropeptide Y (NPY) and proopiomelanocortin (POMC) mRNA in the hypothalamus were also examined because they are important in the regulation of food intake. GALP mRNA was first detected in the arcuate nucleus (ARC) on day 8.

Loss of suppressor-of-fused function promotes tumorigenesis.

The Sonic Hedgehog (SHH) signaling pathway is indispensable for development, and functions to activate a transcriptional program modulated by the GLI transcription factors. Here, we report that loss of a regulator of the SHH pathway, Suppressor of Fused (Sufu), resulted in early embryonic lethality in the mouse similar to inactivation of another SHH regulator, Patched1 (Ptch1). In contrast to Ptch1+/- mice, Sufu+/- mice were not tumor prone.

Functional differences between macaque prefrontal cortex and caudate nucleus during eye movements with and without reward.

The prefrontal cortex and the basal ganglia form mutually connected networks and are thought to play essential roles together in guiding goal-directed behaviors. Yet, these structures seem to have independent pathways to motor outputs as well, suggesting differential contributions to goal-directed behaviors. We hypothesized that the prefrontal cortex guides actions to a direction required by external demands and the basal ganglia guide actions to an internally motivated direction.
