Single-Cell and Spatial Transcriptomics Delineate the Microstructure and Immune Landscape of Intrahepatic Cholangiocarcinoma in the Leading-Edge Area.

Intrahepatic cholangiocarcinoma (ICC) tumor cells and their interactions with the immune microenvironment, particularly at the leading-edge area, have been underexplored. This study employs single-cell RNA sequencing (scRNA-seq) and spatial transcriptome (ST) analysis on samples from the tumor core, adjacent non-tumorous tissue, and the leading-edge area of nine ICC patients. These findings indicate that tumor cells at the leading-edge area demonstrate enhanced proliferation and are tightly associated with the stroma, including endothelial cells and POSTN+ FAP+ fibroblasts.

Validation of red flags in the workup of children with long-term abdominal pain - A retrospective study.

Aim: To evaluate red flags as an instrument to distinguish other medical conditions from Functional Gastrointestinal Disorders (FGID) in children with long-term abdominal pain.

Methods: In a retrospective follow-up, data were collected from 317 children who were referred for medical assessment due to long-term abdominal pain between the years 2011 and 2012 at three Swedish paediatric open clinic units in Sweden. Throughout the review of medical records, any documented red flags at the primary consultation and finally set diagnosis after 1 year were noted for all cases.

Combination of CRISPR-Cas9-RNP and Single-Cell RNAseq to Identify Cell State-Specific FOXJ1 Functions in the Human Airway Epithelium.

The study of the airway epithelium in vitro is routinely performed using air-liquid culture (ALI) models from nasal or bronchial basal cells. These 3D experimental models allow to follow the regeneration steps of fully differentiated mucociliary epithelium and to study gene function by performing gene invalidation. Recent progress made with CRISPR-based techniques has overcome the experimental difficulty of this approach, by a direct transfection of ribonucleoprotein complexes combining a mix of synthetic small guide RNAs (sgRNAs) and recombinant Cas9.

Investigation of Fetuin-A pathway in diabetes mellitus formation in rats exposed to elf magnetic fields.

The presence of technological devices in our lives has increased exposure to environmental electromagnetic fields. As a result of this, especially Cancer and Diabetes are increasing.Rats were divided into 3 groups with 12 rats in each group.

[The role of hyponatremia in the rapid onset of coma after Cyclophosphamide].

Introduction: Cyclophosphamide is an alkylating agent used in routine pulmonary practice, particularly in the management of connectivitis-related diffuse interstitial lung disease. Common side effects are gastrointestinal disorders and immunosuppression, and a sudden and exceptional adverse effect is severe hyponatremia.

Observation: A 78-year-old female patient treated for NSIP-OP in the context of an anti-synthetase syndrome was treated with Cyclophosphamide 15mg/kg.
