Improving adult pulsatile minimal invasive extracorporeal circulation in a mock circulation.

Background: Pulsatile extracorporeal circulation (ECC) may improve perfusion of critical organs during cardiac surgery. This study analyzed the influence of the components of a minimal invasive ECC (MiECC) on the transfer of pulsatile energy into the pseudo-patient of a mock circulation.

Methods: An aortic model with human-like geometry and compliance was perfused by a diagonal pump.

A novel pulsatile blood pump design for cardiothoracic surgery: Proof-of-concept in a mock circulation.

Background: Pulsatile perfusion during extracorporeal circulation is a promising concept to improve perfusion of critical organs. Clinical benefits are limited by the amount of pulsatile energy provided by standard pumps. The present study investigated the properties of a novel positive displacement blood pump in a mock circulation.

An Unprecedented Tolerance to Deletion of the Periplasmic Chaperones SurA, Skp, and DegP in the Nosocomial Pathogen Acinetobacter baumannii.

The outer membrane (OM) of Gram-negative bacteria efficiently protects from harmful environmental stresses such as antibiotics, disinfectants, or dryness. The main constituents of the OM are integral OM β-barrel proteins (OMPs). In Gram-negative bacteria such as Escherichia coli, Yersinia enterocolitica, and Pseudomonas aeruginosa, the insertion of OMPs depends on a sophisticated biogenesis pathway.

[Physical therapy knowledge, skills, and competencies in the care of people with chronic pain].

Background: Between 8 and 16 million people in Germany are affected by chronic pain, causing costs of up to 28.7 billion euros annually. Chronic pain is complex and has biopsychosocial aspects.

A Disease Pathway Framework for Pain Point Identification and Elaboration of Product Requirements Across Patient Care Plan Using Innovation Think Tank Global Infrastructure.

Healthcare providers as well as medical technologists lay a strong focus on clinical conditions for patient centric care delivery. Currently, the challenges are to (1) obtain a consolidated view of various stakeholders and pain points for the entire disease lifecycle, (2) identify interdependencies between different stages of the disease, and (3) prioritize solutions based on customer needs. A structured approach is required to address clinical needs across disease care plans tailored to different geographies and ethnicities.

Loss of LDOC1 expression by promoter methylation in cervical cancer cells.

Cervical cancer lacks reliable prognostic factors for both progression and chemotherapeutic responsiveness. The expression of the LDOC1 tumor suppressor candidate was therefore investigated. In four of six cervical cancer cell lines tested, expression of LDOC1 was silenced.

Analysis of the relationship between the inner structure and the magnitude of atherosclerotic plaques.

The aim of this study was ultrasound evaluation of atherosclerotic plaque morphology in relation to the degree of coronary artery lumen narrowing in patients with ischaemic heart disease. Intravascular ultrasound was performed on 38 patients (30 men and 8 women) aged 35 to 77 (average age 60 +/- 11 years old) with symptoms of ischaemic heart disease. The structure of atherosclerotic plaques with a degree of lumen narrowing of < 50% (1st group) was distinctly different from the structure of plaques with a degree of lumen narrowing of 50-75% (2nd group, p = 0.
