Validation of the Polish version of the Boston Carpal Tunnel Questionnaire, and the influence of treatment for disordered sleep and daytime sleepiness in carpal tunnel syndrome.

Purpose: Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy, with paresthesias and pain in the hand and wrist. CTS is also associated with insomnia and excessive daytime sleepiness (EDS) resulting from the nocturnal exacerbation of symptoms. The Boston Carpal Tunnel Questionnaire (BCTQ) was developed for the assessment of therapeutic outcomes.

Gross anatomic relationship between the human left atrial appendage and the left ventricular summit region: implications for catheter ablation of ventricular arrhythmias originating from the left ventricular summit.

Purpose: The left ventricular summit (LVS) is a source of difficult-to-treat arrhythmias because of anatomical limitations. The aim of this study was to perform detailed research of the left atrial appendage (LAA) anatomy of cadaveric hearts to analyze their complex anatomy and coverage of the LVS.

Methods And Results: Eighty human formalin fixed hearts (mean age 44.

Non-fluoroscopic radiofrequency catheter ablation of right- and left-sided ventricular arrhythmias.

Introduction: Radiofrequency catheter ablation (RFCA) is an important method of treatment of ventricular arrhythmias (VAs). In the majority of RFCA, fluoroscopy is used, exposing patients and medical staff to all related side effects. Current experience of non-fluoroscopic (NF)-RFCA in VAs from the left side is limited.

Heterogeneous Polymeric Particles Encapsulating Human T cells for Controlled Activation, Proliferation, and Delivery.

We report a particulate cell delivery platform, toroidal spiral particles (TSPs), for continuous cell activation, expansion, and local sustained release. Biocompatible TSPs, generated by a self-assembly process of polymeric droplet sedimentation in an aqueous solution and subsequent polymer solidification, possess many engineering design flexibilities to manipulate the microenvironment of the cells to control cell proliferation, migration, and release kinetics. These millimeter-size particles with desired mechanical and physicochemical properties may be potentially used for adoptive cellular therapy (ACT) delivery by a minimally invasive procedure to the tumor mass.

Distinguishing pleiotropy from linked QTL between milk production traits and mastitis resistance in Nordic Holstein cattle.

Background: Production and health traits are central in cattle breeding. Advances in next-generation sequencing technologies and genotype imputation have increased the resolution of gene mapping based on genome-wide association studies (GWAS). Thus, numerous candidate genes that affect milk yield, milk composition, and mastitis resistance in dairy cattle are reported in the literature.
