Magnetic resonance imaging makes it possible to inspect the status of the rotator cuff and the shape of the acromion. To clarify the relationship between acromial shapes and rotator cuff tears, we evaluated magnetic resonance images obtained in 192 shoulders. We classified the acromial shapes into 3 types: type I (flat), type II (curved), and type III (hooked). Among a group of 91 shoulders wit...

OBJECTIVE The purpose of this study was to determine whether occult bony injuries or other characteristic MR abnormalities are frequent in patients suspected of having traumatic tears of the rotator cuff. SUBJECTS AND METHODS MR arthrography of the shoulder was performed in 24 consecutive patients with suspected traumatic tears of the rotator cuff. MR findings were analyzed with regard to abn...

Hydrocarbon liquid dropout can cause a number of problems in gas transmission lines, including increased pressure drop, reduced line capacity, and equipment problems such as compressor damage. To avoid liquid dropout, most current operating specifications for gas transmission lines require that the lines be operated above the hydrocarbon dew point (HDP) or cricondentherm hydrocarbon dew point (...

PURPOSE To determine amounts and biochemical characteristics of substance P-like immunoreactivity (SPLI) in tears of normal human subjects. METHODS Forty-three healthy subjects (16 males and 27 females; age range, 17-80 years) participated. Ten microliters of unstimulated tears were collected with a micropipette from one eye of all subjects. Tear samples were partially purified by C-18 cartri...

INTRODUCTION Meniscal tears are common debilitating injuries that can have dramatic consequences especially for young athletes. Healing of meniscal tears following surgical repair is essentially only feasible for tears within the peripheral, vascular, zone. By comparison, tears that occur within the inner, avascular, zone do not heal and most commonly are treated by excision. This in turn great...

patients and methods seventy patients with chronic partial supraspinatus tears in magnetic resonance imaging were randomized into two groups; prp (n = 35) and pt (n = 35). before the treatment, at the end of the treatment and at the 12th month after the end of the treatment, range of motion (rom), visual analog scale (vas) for pain, disabilities of arm, shoulder and hand questionnaire (dash), n...
