Programming Surface Motility and Modulating Physiological Behaviors of Bacteria via Biosurfactant-Mimetic Polyurethanes.

Modulating microbial motility and physiology can enhance the production of bacterial macromolecules and small molecules. Herein, a platform of water-soluble and amphiphilic peptidomimetic polyurethanes is reported as a means of regulating bacterial surface behavior and the concomitant production of extracellular polymeric substances (EPS). It is demonstrated that carboxyl (-COOH)-containing polyurethanes exhibited 17-fold and 80-fold enhancements in () swarming and twitching areas, respectively.

Clip and Blue-An Easy and Cost-Effective Prechemotherapy Localization Technique in Patients With Breast Cancer Planned for Breast Conservation.

Purpose: Breast conservation after systemic therapy requires accurate localization of the lesion and its margins, especially in nonpalpable tumors. The present study aims to describe a cost-effective technique of tumor localization using the combination of surgical clips and methylene blue.

Methods: A minimum of three or four clips were inserted into the tumor to allow easy visualization of the clip mass.

Guidance for Canadian Breast Cancer Practice: National Consensus Recommendations for Clinical Staging of Patients Newly Diagnosed with Breast Cancer.

The accurate staging of breast cancer is fundamental for guiding treatment decisions and predicting patient outcomes. However, there can be considerable variation in routine clinical practice based on individual interpretation of guidelines and depending on the healthcare provider initially involved in working up patients newly diagnosed with breast cancer, ranging from primary care providers, triage nurses, surgeons, and/or oncologists. The optimal approach for clinical staging, particularly in asymptomatic patients presenting with intermediate-risk disease, remains a topic of dialogue among clinicians.

Guidance for Canadian Breast Cancer Practice: National Consensus Recommendations for the Systemic Treatment of Patients with HER2+ Breast Cancer in Both the Early and Metastatic Setting.

Human epidermal growth factor receptor 2-positive (HER2+) breast cancer is an aggressive subtype of breast cancer associated with a poor prognosis when sub-optimally treated. Recent advances include new and effective targeted therapies that have significantly improved outcomes for patients. Despite these advances, there are significant gaps across Canada, underscoring the need for evidence-based consensus guidance to inform treatment decisions.

Undergraduate dermatology education in Ireland: a survey of interns.

Background: Dermatological conditions are the fourth most common of all diseases affecting humans, and affect almost one third of the world's population, necessitating effective undergraduate dermatology education.

Aims: 1. To enquire about the self-perceived confidence of newly qualified junior doctors in recognising and diagnosing dermatological conditions.
