Is the isolation of S. epidermidis from pre-operative synovial fluid culture a predictor of S. epidermidis prosthetic joint infection?

Pathogen identification is key to the management of periprosthetic joint infection (PJI). Staphylococcus epidermidis is a major cause of PJI. Differentiating between invasive and contaminating S.

Biomechanically induced regulation of Damage-Regulated Autophagy Modulator 1 in periodontal cells and tissues.

Purpose: Autophagy is an important adaptive process for mechanotransduction, in which Damage-Regulated Autophagy Modulator 1 (DRAM1) has a key function in cell fate determination. This study aimed to analyze the influence of biomechanical loading on DRAM1 expression in periodontal cells and tissues.

Methods: Human periodontal ligament (PDL) fibroblasts were stimulated with different pressure protocols, physiological load and overload, in the presence and absence of autophagy inhibitor 3-methyladenine (3-MA) and compared with untreated cells.

Staphylococcus epidermidis alters macrophage polarization and phagocytic uptake by extracellular DNA release in vitro.

Biofilm formation shields Staphylococcus epidermidis from host defense mechanisms, contributing to chronic implant infections. Using wild-type S. epidermidis 1457, a PIA-negative mutant (1457-M10), and an eDNA-negative mutant (1457ΔatlE), this study examined the influence of biofilm matrix components on human monocyte-derived macrophage (hMDM) interactions.

A New Model to Advance a Collaborative Clinical Education Placement Process: A Consortium Core Network.

Background And Purpose: The 2014 Clinical Education (CE) Summit and subsequent scholarly work prompted development of collaborative, mutually beneficial, innovative processes to mitigate CE challenges and inefficiencies. Contemporary practice advocates for collaboration among physical therapist (PT) academic programs (Programs) and clinical partners (Partners) to create a sustainable placement process with mutual benefits for stakeholders. The purpose of this article is to describe the design and implementation of the Ohio Kentucky Consortium of Physical Therapy Educators (Consortium) Consortium Core Network's (CCN) centralized PT CE Placement Process (PT-CEPP) model and share participants' experience perspectives.

Feed injection in liquid chromatography: Reducing the effect of large-volume injections from purely organic diluents in reversed-phase liquid chromatography.

In liquid chromatography (LC), discrepancies in liquid properties such as elution strength and viscosity lead to a mismatch between the sample diluent and mobile phase. This mismatch can result in peak deformation, including peak splitting or even breakthrough, particularly when large sample volumes are injected. The formation of a T-junction between sample solution and mobile phase flow stream, a technique previously used in supercritical fluid chromatography, is the key enabler of feed injection in LC.
