Quorum sensing signals of the grapevine crown gall bacterium, sp. Rr2-17: use of inducible expression and polymeric resin to sequester acyl-homoserine lactones.

Background: A grapevine crown gall tumor strain, sp. strain Rr2-17 was previously reported to accumulate copious amounts of diverse quorum sensing signals during growth. Genome sequencing identified a single luxI homolog in strain Rr2-17, suggesting that it may encode for a AHL synthase with broad substrate range, pending functional validation.

Carbidopa and ZnCarbidopa Induce Reductive Stress in MDA-MB-231 Cells.

The redox imbalance, caused by depletion or generation of reactive oxygen species (ROS), is a key mechanism by which metal complexes exert anticancer effects. Carbidopa has shown the ability to inhibit the MDA-MB-231 cell line, a highly aggressive triple-negative human breast adenocarcinoma, by inducing reductive stress. The metal complex of carbidopa with zinc (ZnCarbi) was designed to modify carbidopa's structure and exhibited increased cytotoxicity against MDA-MB-231 cells.

Clinical and cost-effectiveness of first contact physiotherapy for musculoskeletal disorders in primary care: the FRONTIER, mixed method realist evaluation.

Background: First-contact physiotherapists assess and diagnose patients with musculoskeletal disorders, determining the best course of management without prior general practitioner consultation.

Objectives: The primary aim was to determine the clinical and cost-effectiveness of first-contact physiotherapists compared with general practitioner-led models of care.

Design: Mixed-method realist evaluation of effectiveness and costs, comprising three main phases: A United Kingdom-wide survey of first contact physiotherapists.

A liberalized diet does not improve caloric intake during neutropenia in patients undergoing hematopoietic stem cell transplants: A prospective randomized controlled trial.

Background: The neutropenic diet has been a long-standing approach to preventing infection in patients with hematopoietic stem cell transplants (HSCTs), although data on its efficacy are inconclusive and its restrictive nature might contribute to harm by reducing dietary intake in this patient population who typically experiences poor oral intake. The aim was to determine if a liberalized diet (LD), in comparison with a neutropenic hospital diet (ND), would improve energy intake and lessen weight loss during neutropenia in patients with HSCTs.

Methods: A randomized controlled trial was conducted in a single-center HSCT/hematologic malignancy unit.
