Synchronous BI-RADS category 3 lesions detected by preoperative breast MRI in patients with breast cancer: may follow-up be adequate?

Objective: The purpose of this study was to analyze the rate of malignancy of synchronous Breast Imaging Reporting and Data System (BI-RADS) category 3 lesions identified by preoperative magnetic resonance imaging (MRI) in patients with breast cancer that were followed up rather than biopsied.

Methods: From electronic medical records, we identified 99 patients treated in our institution for whom preoperative breast MRI identified synchronous BI-RADS 3 lesions. Lesion characteristics, rate of second-look ultrasonography (US), rate of collegial decision-making, and rate of biopsies performed during the period of monitoring were analyzed.

[Systematic second opinion review of outside imaging in breast cancer diagnosis: An added value].

Introduction: The systematic second opinion review in cancer centers after breast cancer detection is currently under development. The purposes were the evaluation of review's consequences, in particularly of the axillary staging and the evolution of the delays.

Methods: A retrospective study was conducted on patients who consulted a clinician at Cancer Center of Lorraine in Nancy from January 1st, 2016 to December 31th, 2016.

Inhibitory effect of αS1- and αS2-casein hydrolysates on angiotensin I-converting enzyme in human endothelial cells in vitro, rat aortic tissue ex vivo, and renovascular hypertensive rats in vivo.

A great number of milk-derived peptides have been shown to exhibit angiotensin converting enzyme (ACE) inhibitory properties and thus potential utility in the regulation of blood pressure. The present work aimed to investigate the effects of 2 milk trypsin hydrolysates from alpha(S1)- and alpha(S2)-casein (CH1 and CH2, respectively) on ACE activity evaluated in human umbilical vein endothelial cells (HUVEC) in vitro, rat aortic tissues ex vivo, and renovascular hypertensive rat in vivo. Incubation of HUVEC and rat aortic tissues with CH1 or CH2 induced a concentration-dependent inhibition of hydrolysis of the ACE substrate hippuryl-histidyl-leucine (HHL), the hydrolysates being much less potent than perindopril (an ACE inhibitor).

Expression of Nav1.6 sodium channels by Schwann cells at neuromuscular junctions: role in the motor endplate disease phenotype.

In addition to their role in action potential generation and fast synaptic transmission in neurons, voltage-dependent sodium channels can also be active in glia. Terminal Schwann cells (TSCs) wrap around the nerve terminal arborization at the neuromuscular junction, which they contribute to shape during development and in the postdenervation processes. Using fluorescent in situ hybridization (FISH), immunofluorescence, and confocal microscopy, we detected the neuronal Nav1.
