Epidural Catheter Migration: A Case Report of a CT Scan Examination.

Epidural catheter placement is one of the most effective, secure, and worldwide used pain control modalities. Epidural catheter dislodgment is a common cause of epidural block failure. The diagnosis of this situation is usually presumptive, and cases in which the actual trajectory and final location of the catheter are witnessed by imaging are rare.

Costoclavicular brachial plexus block: A review of current evidence.

The brachial plexus block can be performed through several approaches. The recently described ultrasound-guided costoclavicular block at the costoclavicular space has gained popularity, presenting promising results for upper limb anaesthesia and postoperative analgesia. This block comes as an alternative to the traditional infraclavicular approach, with results suggesting improved block quality and reduced risk of complications.

Evaluation of the proteomic profiles of ejaculated spermatozoa from Saanen bucks ( ).

The Saanen goat breed has been widely explored in breeding programmes; however, there are few reports about the breed's genetic and molecular composition. Thus, this study aimed to characterize the proteomic profile of spermatozoa from Saanen breeding goats. Five breeding animals with proven fertility were selected, the spermatozoa were collected, and the protein was extracted.

Anisotropic nonlinear refractive index measurement of a photorefractive crystal via spatial self-phase modulation.

We show that the refractive index modification photoinduced in a biased nonlinear photorefractive crystal can be accurately measured and controlled by means of a background incoherent illumination and an external electric field. The proposed easy-to-implement method is based on the far-field measurement of the diffraction patterns of a laser beam propagating through a self-defocusing medium undergoing spatial self-phase modulation. For various experimental conditions, both saturation intensity and maximum refractive index modification have been measured.

Diversity of ejaculated sperm proteins in Moxotó bucks ( ) evaluated by multiple extraction methods.

This study aimed to develop protocols for the extraction of sperm proteins from Moxotó goats () and to compare the resulting proteomic maps. The sperm proteins were isolated using an extraction buffer containing 7 M urea and 2 M thiourea, 20 mM DTT, and one of the following detergents: 1% or 4% CHAPS; 1% or 4% SDS; 1% or 4% Triton X-100; or a combination of CHAPS and SDS. The 1-DE and 2-DE profiles of the isolated proteins revealed that the various isolation methods were efficient.
