Axillary Reverse Mapping Using Indocyanine Green in Breast Cancer: Standardization of the Technique.

Purpose: To validate the Axillary Reverse Mapping (ARM) technique with indocyanine green (ICG), focusing on the detection rate and the procedure's feasibility. The predictive factors for metastatic involvement of ARM nodes are also analyzed to define the target population for ARM indication.

Methods: This prospective, observational, non-randomized study of patients with breast cancer included patients with an indication for axillary lymph node dissection (ALND) performed between June 2021 and June 2023.

Highly Rigid, Yet Conformationally Adaptable, Bisporphyrin -Cage Receptors Afford Outstanding Binding Affinities, Chelate Cooperativities, and Substrate Selectivities.

If we aim to develop efficient synthetic models of protein receptors and enzymes, we must understand the relationships of intra- and intermolecular interactions between hosts and guests and how they mutually influence their conformational energy landscape so as to adapt to each other to maximize binding energies and enhance substrate selectivities. Here, we introduce a novel design of cofacial (Zn)bisporphyrin cages based on dynamic imine bonding, which is synthetically simple, but at the same time highly robust and versatile, affording receptors composed of only -hybridized C and N atoms. The high structural rigidity of these cages renders them ideal hosts for ditopic molecules that can fit into the cavity and bind to both metal centers, leading to association constants as high as 10 M in chloroform.

Piloting "From the Inside Out" - a toolkit addressing tuberculosis-related self-stigma.

Background: Self-stigma among people who have tuberculosis (TB) can contribute to non-adherence to medication and disengagement from care. It can manifest in feelings of worthlessness, shame, and guilt, leading to social withdrawal and disengagement from life opportunities. Self-stigma may also affect families of those who have TB, or healthcare workers who treat them.

Probing the Intramolecular Folding of Nucleic Acids with Native Ion Mobility Mass Spectrometry: Strategies and Caveats.

The goal of native mass spectrometry is to obtain information on noncovalent interactions in solution through mass spectrometry measurements in the gas phase. Characterizing intramolecular folding requires using structural probing techniques such as ion mobility spectrometry. However, inferring solution structures of nucleic acids is difficult because the low-charge state ions produced from aqueous solutions at physiological ionic strength get compacted during electrospray.
