Rapid detection of ricin at trace levels in complex matrices by asialofetuin-coated beads and bottom-up proteomics using high-resolution mass spectrometry.

Ricin is a toxic protein regarded as a potential chemical weapon for bioterrorism or criminal use. In the event of a ricin incident, rapid analytical methods are essential for ricin confirmation in a diversity of matrices, from environmental to human or food samples. Mass spectrometry-based methods provide specific toxin identification but require prior enrichment by antibodies to reach trace-level detection in matrices.

Laparoscopic Approach for Ectopic Pregnancy in a Rudimentary Horn: Stepwise Demonstration of Surgical Technique.

Objective: To provide a comprehensive, step-by-step presentation of the laparoscopic resolution of ectopic pregnancy within a rudimentary uterine horn.

Design: A detailed demonstration of the laparoscopic technique presented through narrated video footage.

Setting: Pregnancy occurring in the rudimentary horn of a unicornuate uterus represents a rare form of ectopic pregnancy [1].

Endovascular transplantation of mRNA-enhanced mesenchymal stromal cells results in superior therapeutic protein expression in swine heart.

Heart failure has a poor prognosis and no curative treatment exists. Clinical trials are investigating gene- and cell-based therapies to improve cardiac function. The safe and efficient delivery of these therapies to solid organs is challenging.

2.5-Minute Fast Brain MRI with Multiple Contrasts in Acute Ischemic Stroke.

Purpose: To assess the performance of a 2.5-minute multi-contrast brain MRI sequence (NeuroMix) in diagnosing acute cerebral infarctions.

Methods: Adult patients with a clinical suspicion of acute ischemic stroke were retrospectively included.

[High-risk endometrial carcinoma in early stages: Hospital Italiano de Buenos Aires, oncological results].

Introduction: Endometrial cancer is the second most frequent gynecological tumor in Argentina, representing 6% of all cancers in women. The objective of this study is to evaluate the oncological and perioperative results in patients with high-risk endometrial cancer (HREC) limited to the uterus, treated at the Hospital Italiano de Buenos Aires, between January 2010-2018.

Methods: Retrospective cohort study that evaluated perioperative results, disease-free survival at 2, 4 years in patients with HREC.
