The spread of artemisinin-resistant parasites could lead to higher incidence of patients with malaria complications. However, there are no current treatments that directly dislodge sequestered parasites from the microvasculature. We show that four common antiplasmodial drugs do not disperse rosettes (erythrocyte clusters formed by malaria parasites) and therefore develop a cell-based high-throu...

We describe a source capable of producing single barium ions through nuclear recoils in radioactive decay. The source is fabricated by electroplating (148)Gd onto a silicon α-particle detector and vapor depositing a layer of BaF(2) over it. (144)Sm recoils from the alpha decay of (148)Gd are used to dislodge Ba(+) ions from the BaF(2) layer and emit them in the surrounding environment. The simu...

This paper presents the high-capacity blind text watermarking algorithm that is robust to print and scan operations and this method based on the odd-even quantization. First, segment the binary images of Chinese text characters. And the text image is segmented into the embedded part, adjust part, and dislodge part. After segmentation, the quantization function is built on the basis of invariabl...

The purpose of this study was to determine the effectiveness of ultrasonic vibration in removing Paraposts from extracted teeth. Paraposts were cemented in mandibular premolars to a depth of 9 mm with zinc phosphate cement and the teeth placed in four groups. Group 1 received no vibration. Group 2 received vibration for 4 min, group 3 received vibration for 12 min, and group 4 received vibratio...

Introduction Foreign body cases are common in otolaryngologic practice, usually occurring children. An impacted penetrating impaling foreign can be one of the most challenging emergencies Management revolves around safe extraction object and prevention complications. Here we share our experience with such case unusual at an site, extensive review literature discussing management & complicat...

eral incisors or ectopic teeth into the main archwire can be both difficult and problematic.1 First, the forces used to create space in the arch can oppose those needed to align the teeth. This can cause binding and notching of the wire at the locations of the most misaligned teeth, resulting in increased friction and thus negating the archwire’s superelastic properties.2,3 Potentially harmful ...

We describe a case in which a Weck Hem-o-lok clip (Teleflex, Research Triangle Park, USA) migrated into the collecting system and acted as a nidus for stone formation in a patient after robot-assisted partial nephrectomy. The patient presented 2 years postoperatively with left-sided renal colic. Abdominal computed tomography scan showed a 10 millimeter renal calculus in the left middle pole. Af...

Long posterior wall (LPW) Charnley acetabular implants are widely used as it is believed that the LPW helps to prevent dislocation. This has, however, not been proven statistically. In a preliminary study of these implants removed at revision marked erosion of the LPW was frequently seen, indicating that repetitive impingement may occur. The influence of the long posterior wall was therefore in...
