End-to-side neurorrhaphy in the reconstruction of peripheral segmental neural loss: an experimental study.

Purpose: To evaluate the effects on peripheral neural regeneration of the end-to-side embracing repair technique compared to the autograft repair technique in Wistar rats.

Methods: Fifteen male Wistar rats were divided into three groups with five animals each: denervated group (GD), autograft group (GA), and embracing group (EG). For the evaluation, the grasping test, electroneuromyography (ENMG), and muscle weight assessment were used.

Low cost and easy acquisition: corn grain in microsurgery training.

Objectives: develop an easily accessible model for training the initial motor practice in microsurgery using corn kernels.

Methods: ten corn kernels (Zea mays) were used. A 7mm longitudinal cut was made on one side of the corn grain.

Incisional hernia repair in rats: description of the sublay technique under videomagnification system.

Purpose: To describe the technique of sublay correction of incisional hernia in Wistar rats under videomagnification system.

Methods: Five male rats of the species Rattus norvegicus, of the Wistar lineage, with body weight between 250-350 g and 60 days old were used. Incisional hernia was inducted in all animals.

Do Brazilian medical journals reference Brazilian articles? A cross-sectional study.

Background: The quantity and quality of Brazilian scientific output increases decade by decade. However, there is a tendency to undervalue Brazilian journals, illustrated by the low number of citations compared with texts in international journals, with the tacit justification that foreign articles are of superior quality.

Objectives: To investigate the differences in numbers of citations of Brazilian and international periodicals in three Brazilian journals from 2016 to 2020.

Criteria for assessing peripheral nerve injury. Behavioral and functional assessment in non-operated Wistar rats.

Purpose To evaluate the normality pattern in functional tests of peripheral nerves. Methods Sixty female and sixty male Wistar rats were submitted to vibrissae movement and nictitating reflex for facial nerve; grooming test and grasping test for brachial plexus; and walking tracking test and horizontal ladder test for lumbar plexus. The tests were performed separately, with an interval of seven days between each.
