Staphylococcus aureus enterotoxin sensitization is associated with declined capsaicin cough sensitivity in chronic obstructive pulmonary disease.

Sensitization to Staphylococcus aureus (S. aureus) enterotoxins (SEs) A (SEA) and B (SEB) is associated with the pathogenesis of several chronic airway diseases, including asthma and chronic rhinosinusitis, but its role in chronic obstructive pulmonary disease (COPD) remains unclear. This cohort study aimed to investigate the impact of sensitization to SEs on total IgE levels, and capsaicin cough reflex sensitivity (C-CS) in COPD.

Association of Plasma Nestin With Response to Immune Checkpoint Inhibitors Combined With Chemotherapy in Extensive-stage Small-cell Lung Cancer: A Pilot Study.

Background/aim: Nestin, an intermediate filament protein expressed in stem/progenitor cells of the developing central nervous system, is involved in the progression and poor prognosis of various malignancies. Difficulties in small-cell lung cancer (SCLC) tissue biopsy reduce the accuracy of immunohistochemistry analyses; therefore, evaluating nestin in blood samples is preferred in clinical practice. This study examined the clinical significance of plasma nestin levels in SCLC.

Different molecular recognition by three domains of the full-length GRB2 to SOS1 proline-rich motifs and EGFR phosphorylated sites.

The adaptor protein human GRB2 plays crucial roles in mediating signal transduction from cell membrane receptors to RAS and its downstream proteins by recruiting SOS1. Recent studies have revealed that GRB2 also serves as a scaffold for liquid-liquid phase separation (LLPS) with SOS1 and transmembrane receptors, which is thought to regulate the magnitude of cell signalling pathways. In this study, we employed solution NMR spectroscopy to investigate the interactions of the full-length GRB2 with proline-rich motifs (PRMs) derived from ten potential GRB2-binding sites in SOS1, as well as a peptide from a phosphorylation site of EGFR.

[BRONCHOPULMONARY ASPERGILLOSIS WITH COMORBID GRANULOMATOUS POLYANGIITIS IN A PATIENT WHO PRESENTED WITH EXOPHTHALMOS: A CASE REPORT].

There have been no reports of the coexistence of allergic bronchopulmonary aspergillosis (ABPA) and granulomatosis with polyangiitis (GPA). The first case of ABPA with comorbid GPA that developed exophthalmos is reported. A 69-year-old man was referred to our hospital for exophthalmos, fever, anorexia and weight loss.

Direct evidence for a deprotonated lysine serving as a H-bond "acceptor" in a photoreceptor protein.

Deprotonation or suppression of the pa of the amino group of a lysine sidechain is a widely recognized phenomenon whereby the sidechain amino group transiently can act as a nucleophile at the active site of enzymatic reactions. However, a deprotonated lysine and its molecular interactions have not been directly experimentally detected. Here, we demonstrate a deprotonated lysine stably serving as an "acceptor" in a H-bond between the photosensor protein RcaE and its chromophore.

Endoscopic Transsphenoidal Drainage for Rathke Cleft Cyst With Sellar Xanthogranuloma - Successful Cyst Drainage and Prevention of Postoperative Cerebrospinal Fluid Leakage: 2-Dimensional Operative Video.

The etiology of sellar xanthogranuloma (SXG) remains unclear,1-5 and the surgical strategy for treating SXG is debatable. In this study, we present the surgical case of a symptomatic SXG associated with Rathke cleft cyst. The intraoperative decision to prevent postoperative cerebrospinal fluid (CSF) leakage and secure the drainage route is discussed.

A rare case of a huge malignant pleural mesothelioma presenting in the posterior mediastinum.

We report a case of a 69-year-old woman with pleural mesothelioma presenting in the posterior mediastinum with a maximum diameter of 25 cm. She had a chronic cough and a pleural effusion was noted on chest X-ray. The examination of the effusion showed high hyaluronic acid levels, and mesothelioma was suspected.

Efficacy of dupilumab for severe chronic rhinosinusitis with nasal polyps and asthma: A prospective study.

Background: Dupilumab exerts clinical effects, including improved sinus opacification, olfactory function, and quality of life, in patients with severe chronic rhinosinusitis with nasal polyps (CRSwNPs). Meanwhile, only a few studies have reported its effects on nasal airway resistance and olfactory function, particularly in the Japanese population. Predictors of response remain unclear.

Structure and Dynamics of Drk-SH2 Domain and Its Site-Specific Interaction with Sev Receptor Tyrosine Kinase.

The downstream receptor kinase (Drk), a homologue of human GRB2, participates in the signal transduction from the extracellular to the intracellular environment. Drk receives signals through the interaction of its Src homology 2 (SH2) domain with the phosphorylated tyrosine residue in the receptor tyrosine kinases (RTKs). Here, we present the solution NMR structure of the SH2 domain of Drk (Drk-SH2), which was determined in the presence of a phosphotyrosine (pY)-containing peptide derived from a receptor tyrosine kinase, Sevenless (Sev).

Comorbid functional dyspepsia reflects IL-33-mediated airway neuronal dysfunction in asthma.

Background: Neuronal dysfunction is implicated in the pathophysiology of asthma and functional dyspepsia (FD). However, the relationship between these diseases remains unclear.

Objective: This study aimed to clarify the clinical implications of comorbid FD in asthma and to explore the unified pathway between asthma and FD by focusing on airway neuronal dysfunction.

The safety of perioperative antiplatelet continuation without selection biases in microsurgical decompression surgery for single level lumbar spinal stenosis and lumbar disc herniotomy.

Purpose: Each institution or physician has to decide on an individual basis whether to continue or discontinue antiplatelet (AP) therapy before spinal surgery. The purpose of this study was to determine if perioperative AP continuation is safe during single-level microsurgical decompression (MSD) for treating lumbar spinal stenosis (LSS) and lumbar disc hernia (LDH) without selection bias.

Methods: Patients who underwent single-level MSD for LSS and LDH between April 2018 to December 2022 at our institute were included in this retrospective study.
