Elective tonsillectomy remains one of the most commonly performed operations in otolaryngology, with postoperative hemorrhage (PTH) being the most significant potential complication. Anecdotal evidence among ENT Surgeons suggested that bodybuilding athletes may be at increased risk of suffering from PTH, a notion corroborated by a recent case report, regarding primary PTH. The problem has been ...

SERCA2a is the cardiac-specific isoform of Ca -ATPase of the sarcoplasmic reticulum (SR). A reduction of SERCA2a has been implicated in the contractile dysfunction of heart failure, and partial knockout of the SERCA2 gene (Atp2a2 / mice) reiterated many of the features of heart failure. Yet, mice with a mutation of Atp2a2, resulting in full suppression of the SERCA2a isoform and expression of t...

INTRODUCTION Malaria and HIV-1 infection cause significant morbidity and mortality in children in sub-Saharan Africa. Recurrent malaria infection increases HIV-1 viral load in adults and increases the rate of progression of HIV-1 infection to AIDS. The effect of malaria on viral loads in children living with AIDS (CLWA) is not clearly known. METHODS One hundred thirty five afebrile HIV-1 posi...

Emerging Infectious Diseases • www.cdc.gov/eid • Vol. 10, No. 12, December 2004 2257 species can cause disease (symptomatic infection) and death. C. felis and C. meleagridis infections showed low oocyst shedding (all seven patients had low to moderate oocyst loads in samples). On the contrary, C. parvum produced similar clinical manifestations but showed higher oocyst shedding; 46% had high to ...

BACKGROUND To investigate the accommodative loads change needed to maintain binocular fusion in patients with intermittent exotropia (IXT). METHODS Seventeen consecutive patients with basic IXT and 15 normal controls were recruited. The WAM-5500 autorefractor (GrandSeiko, Fukuyama, Japan) was used to measure refractive error (D) under binocular and monocular viewing conditions at 6 m, 50 cm, ...

BACKGROUND To explore the association between the rupture of posterior cruciate ligament (PCL) and the radial displacement of medial meniscus under the conditions of different flexion and various axial loads. METHODS The radial displacement value of medial meniscus was measured for the specimens of normal adult knee joints, including 12 intact PCLs, 6 ruptures of the anterolateral bundle (ALB...

BACKGROUND There is limited information regarding load responses of the posterior oblique and superficial medial collateral ligaments to applied loads. HYPOTHESES The degree of knee flexion affects loads experienced by the posterior oblique ligament and both divisions of the superficial medial collateral ligament. The posterior oblique ligament provides significant resistance to valgus and in...

In this work, homogeneous thermochemical co-precipitation method was used to fabricate W-25wt%Cu nanocomposite. Synthesized nanocomposite powder was calcined and reduced. A hydrogen atmosphere sintering at 1200oC for 105 consolidated the product up to a density close to 98% theoretical density. Wear experiment were carried out using a pin-ondisc set up at three normal loads of 5, 10 and 15 N an...
