A widespread family of viral sponge proteins reveals specific inhibition of nucleotide signals in anti-phage defense.

Cyclic oligonucleotide-based antiviral signaling systems (CBASS) are bacterial anti-phage defense operons that use nucleotide signals to control immune activation. Here we biochemically screen 57 diverse and phages for the ability to disrupt CBASS immunity and discover anti-CBASS 4 (Acb4) from the phage SPO1 as the founding member of a large family of >1,300 immune evasion proteins. A 2.

MRSA Cellulitis with Orbital and Retinal Abscesses Resulting in Lemierre Syndrome Following Eyebrow Piercing.

We describe a case of orbital cellulitis with abscess formation following eyebrow piercing complicated by internal jugular vein thrombosis and subretinal abscesses requiring enucleation with orbital abscess drainage. The popularity of body piercing is increasing and physicians should be familiar with the possibility and management of vision-threatening complications of facial piercing. Following left eyebrow piercing, a 20-year-old female experienced increasing periorbital swelling, erythema, chemosis, orbital pain, decreased vision, and concomitant fever, chills, and rhinorrhea.

A Literature Review of Methods of Perioperative Pain Management in Thoracic Outlet Decompression.

Objectives: Post-operative pain control in thoracic outlet decompression (TOD) is difficult due to the complex innervation of the anatomical region. Poor post-operative pain control has been associated with worse patient experiences and prolonged inpatient stays. This study aims to identify evidence-based peri-operative analgesic strategies for thoracic outlet decompression.

ACR Appropriateness Criteria® Tracheobronchial Disease.

A variety of thoracic imaging modalities and techniques have been used to evaluate diseases of the trachea and central bronchi. This document evaluates evidence for the use of thoracic imaging in the evaluation of tracheobronchial disease, including clinically suspected tracheal or bronchial stenosis, tracheomalacia or bronchomalacia, and bronchiectasis. Appropriateness guidelines for initial imaging evaluation of tracheobronchial disease and for pretreatment planning or posttreatment evaluation are included.

Unravelling the speed-going relationship: A proof of concept study from British turf flat and jump race meetings.

The maximum galloping speeds of racehorses during a race are influenced by the functional performance of the ground ('going') amongst other factors. For turf racecourses in Britain, the ground is descriptively classified and numerically quantified on the morning of a race meeting by the clerk of the course and subsequently published to assist decision making. Importantly, this includes deciding whether a horse should or should not run.
