Dense biological communities of large epifaunal taxa similar to those found along ridge crest vents at the East Pacific Rise were discovered in abyssal Gulf Mexico. These assemblages occur on a passive continental margin base Florida Escarpment, interface between relatively impermeable hemipelagic clays distal Mississippi Fan and jointed Cretaceous limestone Platform. The fauna apparently is nourished by sulfide rich hypersaline waters seeping out near ambient temperatures onto sea floor.

Background and Purpose —We sought to define an effective safe dose of botulinum toxin type A (Dysport) for the treatment upper limb muscle spasticity due stroke. Methods —This was a prospective, randomized, double-blind, placebo-controlled, dose-ranging study. Patients received either placebo or 1 3 doses Dysport (500, 1000, 1500 U) into 5 muscles affected arm. Efficacy assessed periodically by Modified Ashworth Scale battery functional outcome measures. Results —Eighty-three patients were...

The purpose of this study was to describe MR findings in full-thickness tears the rotator cuff. Of 102 shoulders examined by imaging, 31 were found have a tendon tear at arthroscopy/bursoscopy (five shoulders) or open surgery (26 shoulders). All imaged oblique coronal and axial planes. images evaluated for (1) presence fluid subacromial subdeltoid bursae; (2) abnormal signal supraspinatus, subscapularis, infraspinatus, teres minor tendons; (3) interruption continuity thinning tendon; (4)...

Uncertainty remains about significance increased signal intensity critical zone supraspinatus tendon without visible fibers other secondary findings commonly encountered with abnormalities, such as musculotendinous retraction or obliteration fluid subacromial space.

Short-term case cancellation causes frustration for anesthesiologists, surgeons, and patients leads to suboptimal use of operating room (OR) resources. In many facilities, >10% all cases are cancelled on the day surgery, thereby causing major problems OR management anesthesia departments. The effect hospital type service rate is unclear.In 25 hospitals different types (university hospitals, large community mid- small-size hospitals) we studied elective surgical following subspecialties over...

The signatories of this letter request significant changes to the common practices in palaeontology.With our present, multi-authored comment, we aim argue why these suggestions will not lead improvement both practice and ethics palaeontological research but, conversely, hamper its further development.Although disagree with most contents SVP letter, appreciate initiative discuss scientific underlying ethics.Here, consider different aspects by Rayfield et al. ( 2020) which see weaknesses dangers.

Amber, a natural polymer, is fossil tree resin derived from diverse botanical sources with varying chemical compositions. As such, all amber susceptible to the effects of light, temperature, relative humidity, and oxygen, as well exposure certain chemicals, will deteriorate over time in collections if left unprotected. Here we review approaches for conservation, preparation, imaging specimens their inclusions, address indications causes degradation, recommendations suitable storage...

The magnetic resonance (MR) imaging characteristics of lateral tibial rim (Segond) fractures and their associated injuries were reviewed in 12 patients with radiographic evidence this fracture. Bone marrow adjacent to the fracture emitted a focally abnormal MR signal, which indicated an injury capsular junction. Segond fragment, however, was seen on images only four patients. Associated ligamentous meniscal identified arthroscopy involved anterior (n = 11) medial 7) cruciate ligaments 4) 1)...

After the anaesthetist has induced anaesthesia, it is desirable that surgeon present and ready to start surgery, otherwise team needs wait for surgeon. From another perspective, however, does not necessarily wish be from of induction, since process can take a variable time might occupied in productive activity rather than waiting patient ready. Waiting times morning therefore source constant friction between anaesthetists surgeons. In this prospective study we used data 718 first cases day,...

This investigation evaluated the potential effect of gadolinium (Gd)-DTPA-dimeglumine on synovial membrane and joint cartilage, using macroscopic, microscopic, x-ray fluorescent spectroscopic techniques. Thirteen New Zealand white rabbits (26 knees) were used in this study, ten receiving 500 micromolar injections Gd-DTPA-dimeglumine their right knees; remainder knees served as controls. One injected knee had minimal effusion one mild hyperemia. Microscopically four exhibited focal...
