Abstract Background Robotic-assisted TKA was introduced to enhance the precision of bone preparation and component alignment with goal improving clinical results survivorship TKA. Although numerous reports suggest that knee may be improved using robotic assistance, no long-term randomized trials robotic-assisted have shown whether this in function or Questions/purposes In trial, we compared manual-alignment techniques at follow-up terms (1) functional based on Knee Society, WOMAC, UCLA...

This study was designed to determine whether preoperative VR reduce anxiety in Methods Children scheduled elective surgery under general were randomized into control or group. The group received conventional information regarding and surgery. watched 4-min video showing Pororo, famous little penguin, visiting explaining what is it. main outcome...

Background: The literature lacks studies that confirm whether the improved radiographic alignment can be achieved with computer-navigated total knee arthroplasty improves patients' activities of daily living or durability prostheses. purpose this study was to determine clinical function, alignment, and survivorship components. Methods: We prospectively compared results 520 patients osteoarthritis who underwent for one conventional other. assignment navigation not done randomly. There were...

The purpose of this prospective, randomised study was to evaluate the clinical and radiological results comparing identical cemented or cementless NexGen total knee prostheses implanted bilaterally in same patient. Sequential simultaneous bilateral replacements were performed 50 patients (100 knees). There 39 women 11 men with a mean age 58.4 years (51 67) who received prosthesis one other. follow-up 13.6 (13 14). At final review, Knee Society scores (96.2 (82 100) versus 97.7 (90 100)),...

Cobalt–rhodium heterobimetallic nanoparticle-catalyzed reductive amination of aldehydes and ketones with amines in the presence 5 atm carbon monoxide without an external hydrogen source has been developed. Water added generated situ produces via a water–gas-shift reaction. The reaction can be extended to tandem reduction nitroarenes. catalytic system is stable under conditions could reused eight times losing any activity.

Background/Aims: Inflammatory pseudotumor (IPT) of the liver is a rare disease characterized by chronic infiltration inflammatory cells.However, clinical characteristics and outcomes IPT remain uncertain.Methods: Clinical features, image findings, 55 patients with histologically proven were evaluated.Results: They consisted 26 men 19 women median age 65 years.Serum carcinoembryonal antigen carbohydrate 19-9 levels normal in 42 (93.3%).Enhanced CT scans indicated poorly defined peripheral...

Abstract Background Proponents of computer-assisted TKA suggest that better alignment the TKAs will lead to improved long-term patient functional outcome and survivorship implants. However, there is little evidence about whether position knee components obtained using computer navigation improve function longevity TKA. Questions/purposes The purpose this study was determine (1) clinical results; (2) radiographic CT scan (3) survival rate would be in patients having than results without In...

Long-term results of standard total hip arthroplasty (THA) in young patients were not optimal. There are a number reported disadvantages to longer cementless stems THA including thigh pain and proximal stress shielding. However, it is unknown whether short, metaphyseal-fitting anatomic stem without diaphyseal fixation, which represents possible alternative, will maintain fixation over the term.We therefore evaluated long-term (1) clinical using validated scoring instruments; (2)...

Background: The number of midterm or long-term studies on the current generation cementless total hip replacements with alumina-on-alumina ceramic bearings in patients younger than thirty years age is limited. purpose this study was to evaluate results metaphyseal fitting anatomic prosthesis age, a particular emphasis prevalence thigh pain, resorption bone due stress-shielding proximal part femur, aseptic loosening, and osteolysis. Methods: We reviewed cases ninety-six (127 hips) who had...

There have been comparatively few studies of the incidence osteolysis and survival hybrid cementless total hip replacements (THRs) in patients younger than 50 years age. We prospectively reviewed 78 (109 hips) with a THR having mean age 43.4 (21 to 50) 79 (110 46.8 49). The were evaluated clinically using Harris score, Western Ontario McMaster Universities (WOMAC) osteoarthritis score University California, Los Angeles (UCLA) activity score.

Background: The available comparative studies of computer navigation-assisted and conventional knee arthroplasties have short-term follow-up periods. Therefore, the clinical benefits after long-term are not clear. purposes current study were to compare outcomes, alignment components, prevalence aseptic loosening implant survival, complications total performed with without navigation. Methods: We prospectively compared results 162 consecutive patients (324 knees) osteoarthritis. These had...

Autophagy is essential to maintain tissue homeostasis, particularly in long-lived cells such as cardiomyocytes. Whereas many studies support the importance of autophagy mechanisms underlying obesity-related cardiac dysfunction, role lipid metabolism remains unclear. In heart, lipotoxicity exacerbated by lipoprotein lipase (LPL), which mediates accumulation fatty acids heart through intravascular triglyceride (TG) hydrolysis. both genetic and dietary models obesity, we observed a substantial...

A cobalt–rhodium heterobimetallic nanoparticle-catalyzed reductive cyclization of 2-(2-nitroaryl)acetonitriles to indoles has been achieved. The tandem reaction proceeds without any additives under the mild conditions (1 atm H2 and 25 °C). This procedure could be scaled up gram scale. catalytic system is significantly stable these reused more than ten times loss activity.
