Ultrasonography in the diagnosis of rotator cuff avulsion fracture.

Deepening the understanding of morphology and corresponding sonographic features of the greater tuberosity and the various fracture lines in avulsion fracture like the "horizontal line sign" and "double-line sign" and sharp bony prominence besides the defect on the greater tuberosity, can make it simple to identify avulsion fracture accurately and quickly.

Targeting metabolic driving and minimization of by-products synthesis for high-yield production of D-pantothenate in Escherichia coli.

Background: d-Pantothenate (DPA) is an important functional chemical that has been widely applied in healthcare, cosmetics, animal food, and feed industries.

Methods And Results: In this study, a high-yield DPA-producing strain was constructed by metabolic engineering strategies with targeting metabolic driving and by-products minimization. The metabolic driving force of push and pull was firstly obtained to improve the production of DPA via enrichment of precursor pool and synthetic pathway, accumulating 4.

Efficient production of an ezetimibe intermediate using carbonyl reductase coupled with glucose dehydrogenase.

Ezetimibe is a top-selling hypolipidemic drug for the treatment of cardiovascular diseases. Biosynthesis of (4S)-3-[(5S)-5-(4-fluorophenyl)-5-hydroxypentanoyl]-4-phenyl-1,3-oxazolidin-2-one ((S)-ET-5) using carbonyl reductase has shown advantages including high catalytic efficiency, excellent stereoselectivity, mild reaction conditions, and environmental friendness, and was considered as the key step for ezetimibe production. The regeneration efficiency of the cofactor, nicotinamide adenine dinucleotide (phosphate) (NAD(P)H) is one of the main restricted factor.

The Value of Percutaneous Shoulder Puncture with Contrast-enhanced Ultrasound in Differentiation of Rotator Cuff Tear Subtypes: A Preliminary Prospective Study.

Imaging tests perform relatively well in the detection of rotator cuff tears (RCTs), exhibiting high sensitivity and specificity, mainly among larger full-thickness tears (tear width >1 cm). However, these tests are relatively less accurate in the detection of small full-thickness tears and partial-thickness tears. The purpose of this study was to determine the feasibility of percutaneous ultrasound-guided tendon lesionography (PUTL) using the SonoVue and the value of percutaneous shoulder puncture via contrast-enhanced ultrasound (CEUS)-a combination of percutaneous ultrasound-guided subacromial bursography (PUSB) and PUTL-in the detection of RCT subtypes.
