The utility of the irritability scale in Huntington's disease patients with evidence of irritability or aggression.

Introduction: Irritability, a common neuropsychiatric symptom in Huntington's disease (HD), lacks a standardized measurement. The Irritability Scale (IS), tailored for HD, has patient and informant versions, but variable interrater agreement has been reported frequently in previous studies. To enhance the clinical utility of the IS, this study aimed to identify the most reliable components estimating the underlying construct and develop a shortened version for time-limited contexts.

KF-catalyzed direct thiomethylation of carboxylic acids with DMSO to access methyl thioesters.

With dimethyl sulfoxide (DMSO) as the methylthio source, a KF-catalyzed strategy was employed for the direct thiomethylation of carboxylic acids with DMSO for the preparation of methyl thioesters. In this process, a wide range of methyl thioesters were obtained in moderate to excellent yields. This novel strategy features the first use of DMSO as a methylthiolating agent for the construction of methyl thioesters, transition metal-free conditions, inexpensive reagents, easy workup, broad substrate scope and sustainability.

Giant Multilocular-Cystic Metaplastic Thymoma: A Case Report.

The metaplastic thymoma with giant multilocular-cyst formation had not been documented. The metaplastic thymoma is an extremely rare primary thymic epithelial tumor with an indolent clinical course. It is characterized by a histologic biphasic appearance, which is consisted of solid epithelial areas and spindle cells as the background.

Clinicopathologic features, tumor immune microenvironment and genomic landscape of EBV-related and EBV-unrelated poorly differentiated nonkeratinizing squamous cell carcinoma of the thymus.

Objectives: Knowledge regarding thymic EBV-related poorly differentiated nonkeratinizing squamous cell carcinoma (PDNKSCC), also known as lymphoepithelial carcinoma (LEC), is extremely limited due to its rarity.

Materials And Methods: This multi-institutional study enrolled 85 patients with thymic PDNKSCC. DNA in situ hybridization was performed to evaluate the EBV status of all 85 cases.

Clear cell sarcoma of soft tissue with plasmacytoid morphology: A rare case report.

Rationale: Clear cell sarcoma of soft tissue (CCSST) is a rare malignant tumor that occurs in the extremities of young adults. CCSST has been documented to have atypical histopathological features, such as epidermotropism or myxoid differentiation, which may set pitfalls in the differential diagnosis. We report a case of CCSST with plasmacytoid morphology which has never been described.

Diffuse midline glioma with H3-K27M mutation: A rare case with GFAP-positive anucleate whorled patterns.

Introduction: Diffuse midline glioma with H3-K27M mutation is an infiltrative high-grade glioma, with predominantly astrocytic differentiation.

Patient Concerns: A 54-year-old Chinese woman presented with memory loss for a month and walking instability for 15 days.

Diagnosis: Magnetic resonance imaging showed a mass shadow of isometric T1 and slightly longer T2 with mild mixed signals in the third ventricle of the suprasellar region.

[Corrigendum) RNA interference‑mediated FANCF silencing sensitizes OVCAR3 ovarian cancer cells to adriamycin through increased adriamycin‑induced apoptosis dependent on JNK activation.

After the publication of the article, an interested reader drew to the authors' attention that there appeared to be a pair of overlapping data panels in Fig. 4C on p. 1726 [specifically, the 'Untransfected' and 'Control shRNA' data panels for the ADM (24 h) experiments].

Undifferentiated Large Cell Carcinoma of the Thymus Associated with Plasma-Cell Type Castleman Disease-Like Reaction: A Case Series.

Undifferentiated large cell carcinoma of the thymus with a Castleman disease (CD)-like reaction is a thymic carcinoma accompanied by an inflammatory reaction closely resembling the morphological features of CD. This disease is extremely rare and distinctive, only five cases have been documented in a single report, and all five cases were associated with a reaction like the hyaline vascular type CD. For the first time, we report two cases of undifferentiated large cell carcinoma of the thymus with a plasma cell type CD-like reaction.

PTP-PEST Regulated Membranous/Cytoplasmic Translocation of p120ctn in the Lung Cancer Resistance to Tyrosine Kinase Inhibitor.

Our previous studies indicate that resistance induction using first-generation tyrosine kinase inhibitors (TKIs) in lung cancer is accompanied with p120-catenin (p120ctn) cytoplasmic translocation from the membrane. However, the molecular mechanism underlying p120ctn intracytoplasmic translocation has not yet been reported. We performed immunohistochemistry to detect the correlation of p120ctn distribution with protein tyrosine phosphatase non-receptor type 12 (PTP-PEST) and p120ctn Y335 phosphorylation levels in non-small cell lung cancer (NSCLC) patients.

Diagnosis of NUT Carcinoma Despite False-Negative Next-Generation Sequencing Results: A Case Report and Literature Review.

Nuclear protein in testis (NUT) carcinoma (NC) is a poorly differentiated malignant tumor with a poor prognosis, which is caused by the gene rearrangement. Positive staining of NUT using immunohistochemistry (IHC) or gene rearrangement of revealed by genetic analysis, such as fluorescence in situ hybridization (FISH) or next-generation sequencing (NGS), are important strategies used for accurate diagnosis. In the current study, we present a case of NC in an 18-year-old man who had a chief complaint of nasal congestion, nasal bleeding, and anosmia.

Bronchiolar Adenoma Transforming to Invasive Mucinous Adenocarcinoma: A Case Report.

Bronchiolar adenoma (BA) is recognized as a neoplasm with benign clinical course. Histologically, BA is characterized by nodular proliferation of the bilayered bronchiolar-type epithelium, including multipartite epithelial cells and a continuous layer of basal cells. Recent reports have revealed the frequent presence of driver gene mutations in BA, suggesting its neoplastic nature.

Supratentorial ependymoma with YAP1:FAM118B fusion: A case report.

We report a case of a 26-year-old Chinese man who had experienced three grand mal seizures in the past two months. Magnetic resonance imaging revealed a relatively well-circumscribed lesion in the left frontal lobe. A craniotomy with total excision of the tumor was performed.

HPV 16 E6/E7 Promote the Glucose Uptake of GLUT1 in Lung Cancer Through Downregulation of TXNIP Due to Inhibition of PTEN Phosphorylation.

High-risk human papillomavirus (HPV) infection play an important role in the development of lung cancer. Our previously study showed that E6 and E7 in HPV16 upregulated the expression of GLUT1 in lung cancer cells. However, whether they can promote the glucose uptake by GLUT1 and the underlying molecular mechanism has not been identified.

Genomic Study of Chinese Quadruple-negative GISTs Using Next-generation Sequencing Technology.

Purpose: Approximately 10% of gastrointestinal stromal tumors (GISTs) are devoid of KIT, PDGFRA (platelet-derived growth factor-alpha), BRAF, and SDH alterations. The aim of this study was to characterize molecular drivers in Chinese patients with quadruple-negative GISTs.

Patients And Methods: In 1022 Chinese patients with GIST, mutations of KIT and PDGFRA were analyzed by direct sequencing.

HPV16 E6/E7 promote the translocation and glucose uptake of GLUT1 by PI3K/AKT pathway relieving miR-451 inhibitory effect on CAB39 in lung cancer cells.

Background: HPV16 E6/E7 proteins are the main oncogenes and only long-term persistent infection causes lung cancer. Our previous studies have shown that HPV16 E6/E7 protein up-regulates the expression of GLUT1 in lung cancer cells. However, whether E6 and E7 protein can promote the glucose uptake of GLUT1 and its molecular mechanism are unclear.

First case of bronchiolar adenoma lined purely by mucinous luminal cells with molecular analysis: A case report.

Rationale: Bronchiolar adenoma (BA) is a newly designated rare entity of the lung, including both the currently designated ciliated muconodular papillary tumor (CMPT) and so-called non-classic CMPT. The most prominent histological feature of BAs is the bilayered cell structures composed of the continuous basal cell layer and the luminal layer which consists of different proportion of mucinous cells, ciliated cells, Clara cells and/or type II pneumocytes. BA purely covered by mucinous cells without other components in the luminal layer has never been reported.
