The pivotal role of PACAP/PAC1R signaling from the anterior insular cortex to the locus coeruleus on anxiety-related behaviors of mice.

The neuropeptide pituitary adenylate cyclase-activating polypeptide (PACAP) and its specific receptor (PAC1R) are widely present in the central nervous system (CNS), and PACAP/PAC1R signaling has been implicated in anxiety-related behaviors. The locus coeruleus (LC), with its extensive noradrenergic (NA) projections throughout the CNS, is also implicated in anxiety. Although the LC exhibits a high expression of PAC1R, the precise role of PACAP/PAC1R signaling in the LC's involvement in anxiety remains unclear.

Radiographic scores as a predictor of oxygenation index in very low-birthweight infants.

Background: Very low birthweight infants (VLBWIs) often undergo chest radiographic examinations without standardization or objectivity. This study aimed to assess the association of two radiographic scores, the Brixia and radiographic assessment of lung edema (RALE), with oxygenation index (OI) in ventilated VLBWIs and to determine the optimal cutoff values to predict hypoxic respiratory severity.

Methods: VLBWIs who received invasive respiratory support with arterial lines between January 2010 and October 2023 were enrolled in this study (n = 144).

Significance of P53-Binding Protein 1 as a Novel Molecular Histological Marker for Hypopharyngeal Squamous Neoplasms.

The DNA damage response protein p53-binding protein 1 (53BP1) accumulates and forms foci at double-strand DNA breaks, indicating the extent of DNA instability. However, the potential role of 53BP1 as a molecular biomarker for hypopharyngeal squamous cell carcinoma (HPSCC) diagnosis remains unknown. Here, we evaluated the potential of immunofluorescence-based analysis of 53BP1 expression to differentiate the histology of hypopharyngeal neoplasms.

Long-term prognosis and DNA damage status after oral mucosal epithelial cell sheet transplantation following esophageal endoscopic submucosal dissection for squamous cell carcinoma: A case series.

Autologous oral mucosal epithelial cell sheet (AOMECS) transplantation has recently been applied in human patients to prevent postprocedural stenosis following endoscopic submucosal dissection (ESD) for esophageal squamous cell carcinoma. However, the long-term safety of AOMECS transplantation remains unclear. We evaluated the long-term outcomes of 10 patients who participated in a clinical trial of AOMECS transplantation after esophageal ESD.

F-fluorodeoxyglucose positron emission tomography/computed tomography parameters are associated with histological outcomes in superficial esophageal squamous cell carcinoma.

Endoscopic submucosal dissection is a standard treatment for early esophageal squamous cell carcinoma. However, submucosal or lymphovascular invasion increases the risk of lymph node metastasis. Although F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) parameters are associated with prognosis in patients with advanced esophageal squamous cell carcinoma, the utility of FDG PET/CT in diagnosing superficial esophageal carcinoma remains unclear.

Localization of the MTP4 transporter to trans-Golgi network in pollen tubes of Arabidopsis thaliana.

Zinc (Zn) is an essential element for plants. Numerous proteins in different cellular compartments require Zn for their structure and function. Zn can be toxic when it accumulates in high levels in the cytoplasm.

Development of a score model to predict long-term prognosis after community-onset pneumonia in older patients.

Background And Objective: The identification of factors associated with long-term prognosis after community-onset pneumonia in elderly patients should be considered when initiating advance care planning (ACP). We aimed to identify these factors and develop a prediction score model.

Methods: Patients aged 65 years and older, who were hospitalized for pneumonia at nine collaborating institutions, were included.

Prediction of Co-Occurrence of Lewy Body Disease with Alzheimer's Disease.

Identifying the coexistence of Lewy body (LB) pathology with Alzheimer's disease (AD) in clinical practice is important in the era of anti-amyloid-β antibody therapy. However, few studies have predicted the presence of comorbid LB pathology with AD using indicative biomarkers of dementia with Lewy bodies or by collecting detailed clinical symptoms. We report the clinical progression of a 67-year-old patient diagnosed with AD who developed rapid eye movement sleep disorder-like symptoms and transient visual hallucinations 10 years after AD onset and was considered to have comorbid LB pathology based on imaging indicative biomarkers of dementia with Lewy bodies.

Diagnostic performance of linked color imaging for gastric cancer by Helicobacter pylori infection status: A subanalysis of the large-scale, multicenter randomized controlled trial LCI-FIND.

Background: Linked color imaging (LCI) is a new image enhancement technology that facilitates the recognition of subtle differences in mucosal color. In the large-scale, multicenter randomized controlled trial LCI-FIND, LCI demonstrated good diagnostic performance for the detection of tumor lesions in the upper gastrointestinal tract. The aim of the present study was to exploratively evaluate the diagnostic performance of LCI according to H.

A first-in-human clinical study of laparoscopic autologous myoblast sheet transplantation to prevent delayed perforation after duodenal endoscopic mucosal dissection.

Background: The detection rate of superficial non-ampullary duodenal epithelial tumors (SNADETs) has recently been increasing. Large tumors may contain malignant lesions and early therapeutic intervention is recommended. Endoscopic mucosal dissection (ESD) is considered a feasible treatment modality, however, the anatomical and physiological characteristics of the duodenum create a risk of postoperative perforation after ESD.

(1) : Delayed perforation after gastric endoscopic submucosal dissection (ESD) for early gastric cancer is a relatively uncommon and serious complication that sometimes requires emergency surgery. This study aimed to determine the clinicopathological features, risk factors, and appropriate management strategies for delayed perforation. (2) : This study included 735 patients with 791 lesions who underwent ESD for early gastric cancer at a single institution between July 2009 and June 2019.

Colonic intussusception after endoscopic mucosal resection successfully managed by endoscopic procedure.

Adult-onset intussusception, particularly associated with colonoscopy, is extremely rare. A 78-year-old man, referred to our hospital for colonic endoscopic mucosal resection (EMR), experienced subsequent dull abdominal pain, as well as elevated peripheral blood leukocytosis and C-reactive protein levels. Abdominal computed tomography (CT) revealed a colocolonic intussusception at the hepatic flexure.

The prediction of estimated cerebral perfusion pressure with trans-systolic time in preterm and term infants.

It is important to monitor cerebral perfusion in infants because hypo- and hyperperfusion can contribute to neurological injury. This study aimed to clarify the relationship between trans-systolic time (TST) and critical closing pressure (CrCP) or estimated cerebral perfusion pressure (CPPe) in neonates. Moreover, we aimed to determine the TST values in preterm and term infants with stable cerebral perfusion to clarify normative reference data.

A high α1-antitrypsin/interleukin-10 ratio predicts bacterial pneumonia in adults with community-acquired pneumonia: a prospective cohort study.

Background: Current microbiological tests fail to identify the causative microorganism in more than half of all pneumonia cases. We explored biomarkers that could be used for differentiating between bacterial and viral pneumonia in patients with community-acquired pneumonia (CAP).

Methods: In this prospective cohort study conducted in Japan, data obtained from adult patients with bacterial pneumonia, including bacterial and viral coinfections (bacterial pneumonia [BP] group), and purely viral pneumonia (VP group) at diagnosis were analyzed using multivariate logistic regression analysis to identify predictors of bacterial pneumonia.

Oligomerization Mechanisms of Tea Catechins Involved in the Production of Black Tea Thearubigins.

Thearubigins (TRs) are chemically ill-defined black tea pigments composed of numerous catechin oxidation products. TRs contain oligomeric components; however, the oligomerization mechanisms are poorly understood. The comparison of the C nuclear magnetic resonance (NMR) spectra of TRs with different molecular sizes suggested the participation of A-ring methine carbons in the oligomerization.

Gargle sample is an effective option in a novel fully automated molecular point-of-care test for influenza: a multicenter study.

Background: We conducted a multicenter study to evaluate the performance of a novel fully automated molecular point-of-care test using transcription-reverse transcription concerted reaction that can detect influenza A and B within 15 min in nasopharyngeal swabs and gargle samples (TRCsatFLU).

Materials And Methods: This retrospective study included 103 consecutive SNADET patients (103 lesions) who underwent CEMR, UEMR, or UEMR-SIM. The UEMR-SIM procedure included (1) marking and submucosal injection, (2) filling of the duodenal lumen with 0.

Spinal Astrocyte-Neuron Lactate Shuttle Contributes to the Pituitary Adenylate Cyclase-Activating Polypeptide/PAC1 Receptor-Induced Nociceptive Behaviors in Mice.

We have previously shown that spinal pituitary adenylate cyclase-activating polypeptide (PACAP)/PACAP type 1 (PAC1) receptor signaling triggered long-lasting nociceptive behaviors through astroglial activation in mice. Since astrocyte-neuron lactate shuttle (ANLS) could be essential for long-term synaptic facilitation, we aimed to elucidate a possible involvement of spinal ANLS in the development of the PACAP/PAC1 receptor-induced nociceptive behaviors. A single intrathecal administration of PACAP induced short-term spontaneous aversive behaviors, followed by long-lasting mechanical allodynia in mice.

Efficacy and safety of vonoprazan-based regimen for Helicobacter pylori eradication therapy in Japanese adolescents: a prospective multicenter study.

Background: Vonoprazan (VPZ)-based regimen for Helicobacter pylori (H. pylori) is safe and more efficacious than the proton pump inhibitor-based regimen mainly in adults. This study aimed to evaluate the efficacy and safety of a VPZ-based regimen for H.

Cytomegalovirus Graft Duodenitis Diagnosed by Transanal Double-Balloon Endoscopy Technique in an Enteric-Drained Pancreas Transplant Recipient: A Case Report.

Duodenal graft complications are not uncommon after pancreas transplant (PTx). Although direct visualization and biopsy of the duodenal graft are important for accurate diagnosis and management, endoscopic access is often limited in cases of enteric-drained PTx. Herein, we present a case of cytomegalovirus (CMV) graft duodenitis that was successfully diagnosed by transanal endoscopy using the double-balloon technique.

The Pivotal Role of Neuropeptide Crosstalk from Ventromedial-PACAP to Dorsomedial-Galanin in the Appetite Regulation in the Mouse Hypothalamus.

We have previously shown that pituitary adenylate cyclase-activating polypeptide (PACAP) in the ventromedial hypothalamus (VMH) enhances feeding during the dark cycle and after fasting, and inhibits feeding during the light cycle. On the other hand, galanin is highly expressed in the hypothalamus and has been reported to be involved in feeding regulation. In this study, we investigated the involvement of the VMH-PACAP to the dorsomedial hypothalamus (DMH)-galanin signaling in the regulation of feeding.

Linked color imaging provides enhanced visibility with a high color difference in upper gastrointestinal neoplasms.

Background And Aim: The aim of this post-hoc analysis in a randomized, controlled, multicenter trial was to evaluate the visibility of upper gastrointestinal (UGI) neoplasms detected using linked color imaging (LCI) compared with those detected using white light imaging (WLI).

Methods: The visibility of the detected UGI neoplasm images obtained using both WLI and LCI was subjectively reviewed, and the median color difference (ΔE) between each lesion and the surrounding mucosa according to the CIE L*a*b* color space was evaluated objectively. Multivariate logistic regression analysis was performed to identify factors associated with neoplasms that were missed under WLI and detected under LCI.

Rapid and chronological expression of angiogenetic genes is a major mechanism involved in cell sheet transplantation in a rat gastric ulcer model.

Introduction: Cell sheet technology has been applied in the treatment of patients with severe cardiac failure. Although the paracrine effect of cell sheets accelerating angiogenesis is thought to be the intrinsic mechanism for improvement of cardiac function, little is known about how a cell sheet would function in the abdomen.

Methods: We used acetic acid-induced gastric ulcer rat model to elucidate the mechanisms of myoblast sheet transplantation in the abdomen.
