Objective. The purpose of this investigation was to describe two sonographically guided popliteus tendon sheath injection techniques and determine their accuracy in a cadaveric model. Methods. A single experienced operator completed 24 sonographically guided popliteus tendon sheath injections, 12 using a longitudinal approach and 12 using a transverse approach relative to the tendon. The inject...

Tendon sheath fibromas are rare, benign soft tissue tumors that are predominantly found in the fingers, hands, and wrists of young adult men. This article describes a tendon sheath fibroma that developed in the thigh of a 70-year-old man, the only known tendon sheath fibroma to form in this location. Similar to tendon sheath fibromas that develop elsewhere, our patient's lesion presented as a p...

OBJECTIVES Evaluate ENT endoscope sheaths as barriers to virus passage. STUDY DESIGN "Defective" sheaths covering an endoscope were challenged with virus to determine how many virus particles could be recovered from the endoscope. METHODS Sheaths with small laser-drilled holes (2 to 30 microm) were challenged with high-titer virus suspensions (10(8) viruses/mL). The inside of the sheath and...

Isolated mesophyll cells and bundle sheath cells of Digitaria sanguinalis were used to study the light-absorbing pigments and electron transport reactions of a plant which possesses the C(4)-dicarboxylic acid cycle of photosynthesis. Absorption spectra and chlorophyll determinations are presented showing that mesophyll cells have a chlorophyll a-b ratio of about 3.0 and bundle sheath cells have...

The design of cement slurry for horizontal wellbores is challenging as it must present very high quality cement slurry properties e.g. zero free water, less than 50 cc API fluid loss value, appropriate rheology and yield point for effective displacement, adequate compressive strength, which is critical for lightweight slurries, and finally stable cement column behind casing. The main objective ...

RATIONALE The combination of an ultrathin bronchoscope, navigational technology, and endobronchial ultrasound (EBUS) seems to combine the best of mutual abilities for evaluating peripheral pulmonary lesions, but ultrathin bronchoscopes that allow the use of EBUS have not been developed so far. OBJECTIVES To compare the diagnostic yield of transbronchial biopsy under EBUS, fluoroscopy, and vir...

During the oxide layer etching process, particles in capacitively coupled plasma equipment adhere to wafer edge and cause defects that reduce yield from semiconductor wafers. To particle contamination equipment, we propose changes voltage temperature of electrostatic chuck, discharge sequence, gas flow, pressure parameters during process. The proposed reduction method was developed by analyzing...

In an on-going effort of the FoSHoL project of ActionAid Bangladesh to evaluate the farmers’ perception and effect of system of rice intensification on the yield, 85 farm families of Tala, Satkhira Sadar, Biswamvampur, Noakhali, Ulipur and Koira Upazilla of Satkhira, Sunamganj, Noakhali, Kurigram and Khulna districts conducted the study in their own lands in a participatory action research appr...

A patient with acquired immunodeficiency syndrome (AIDS) developed crytpococcal meningitis, complicated by papilledema and severe progressive visual loss despite medical therapy. Bilateral optic sheath fenestration resulted in significant improvement in vision and resolution of papilledema. Histopathologic evaluation of the optic nerve sheath demonstrated numerous cryptococci. Optic nerve sheat...
