Field-Deployable Computer Vision Wood Identification of Peruvian Timbers.

Illegal logging is a major threat to forests in Peru, in the Amazon more broadly, and in the tropics globally. In Peru alone, more than two thirds of logging concessions showed unauthorized tree harvesting in natural protected areas and indigenous territories, and in 2016 more than half of exported lumber was of illegal origin. To help combat illegal logging and support legal timber trade in Peru we trained a convolutional neural network using transfer learning on images obtained from specimens in six xylaria using the open source, field-deployable XyloTron platform, for the classification of 228 Peruvian species into 24 anatomically informed and contextually relevant classes.

Structural evaluation of plasma alpha2-macroglobulin in acute pancreatitis.

In this work we evaluate the proteolytic state of plasma alpha2-macroglobulin in acute pancreatitis. In addition, the plasma activity of matrix metalloproteinase-2 (MMP-2), MMP-9 and serine proteinases were analyzed. A total of 33 patients with acute pancreatitis were studied, of whom 16 were diagnosed as having mild and 17 as having severe acute pancreatitis.

[Acute carotid thrombosis in penetrating traumatism: is revascularization necessary in the patient without central neurological deficit?].

Introduction: Carotid lesions require priority in both evaluation and treatment due to their high morbidity and mortality. Controversy about therapeutic behavior in these patients with or without central neurological deficit is still under in discussion.

Objectives: To present a patient with acute carotid thrombosis due to a shotgun wound and discuss its therapeutic behavior.

[Present state in the surgical treatment of acute cecal diverticulitis].

Background: Cecal acute diverticulitis is a rare disease with symptoms similar to acute appendicitis and is therefore difficult to diagnose.

Objectives: To evaluate therapeutical conduct according to clinical for ms of presentation and the intraoperative findings.

Location: Emergency Service of Clinical National Hospital.
