Clinical Efficacy of Preoperative CT-Assisted Planning for Primary Total Knee Arthroplasty: A Pilot Randomized Clinical Trial.

This study aims to determine the mean posterior condylar angle (PCA) in the included population and its relation to coronal alignment; and to know the clinical importance of the use of preoperative computed tomography (CT) scan in total knee arthroplasty (TKA). We randomized 50 patients with primary knee osteoarthritis into 2 groups. We used CT scan axial images to measure the PCA.

Medial Meniscus Posterior Root Tear Repair Using a 2-Simple-Suture Pullout Technique.

Medial meniscus posterior root tear is one of the underestimated knee injuries in terms of incidence. Despite its grave sequelae, using simple but effective technique can maintain the native knee joint longevity. In the current note, a 2-simple-suture pullout technique was used to effectively reduce the meniscus posterior root to its anatomic position.

Tumor necrosis factor gene expression in regular hemodialysis patients.

This study evaluates tumor necrosis factor (TNF)-alfa gene expression in patients with end-stage renal disease (ESRD) on regular hemodialysis as an expression of cardiovascular disease (CVD) risk even on a sub-clinical level and its relation to some of the parameters incriminated in the pathogenesis and the establishment of uremic arteriopathy. A total of 51 patients with ESRD on regular hemodialysis and 20 healthy subjects matching in age and gender as a control group were recruited. All selected cases were subjected to serum lipid profile, Creactive protein (CRP), TNF-alfa gene expression and Doppler study of carotid arteries to estimate carotid intimal media thickness (cIMT).

MyD88 and Src are differentially regulated in Kupffer cells of males and proestrus females following hypoxia.

Hypoxia produces sex dimorphic immune responses in males and proestrus females. Because Kupffer cells are the major source of proinflammatory cytokines, studies were conducted to discern IL-6 production in mouse Kupffer cells following hypoxia. Hypoxia enhances TLR4 expression in Kupffer cells irrespective of sex.

Transgenic prolactin-/- mice: effect of trauma-hemorrhage on splenocyte functions.

Prolactin (PRL) is involved in the regulation of immune functions under normal and pathological conditions. Trauma-hemorrhage (T-H) produces profound immunosuppression in male mice but not in proestrus female mice. Administration of PRL in males after T-H, however, restores immune functions.
