Ruthenium nanoparticles supported on hydroxyapatite as an efficient and recyclable catalyst for cis-dihydroxylation and oxidative cleavage of alkenes

Impregnation of hydroxyapatite with colloidal ruthenium results in the formation of a catalyst that effects cis-dihydroxylation and oxidative cleavage of alkenes to their respective cis-1,2-diols and carbonyl products in good to excellent yields (see scheme). The supported ruthenium catalyst can be easily recycled and reused for consecutive reaction runs without significant deterioration of the catalytic activities. R1, R2 = H, alkyl, aryl.postprin

Reconstructive surgery for burn patients

Reconstructive surgery in burn patients is difficult because of the intense scarring and the necessity to carry out multiple operative procedures for different reconstructive needs in a single patient. The primary aim of the surgeon is to prevent hypertrophic scar by early wound closure, and proper postburn treatment using a combination of silicone gel, splinting, and pressure therapy. Reconstructive procedures should be deferred until the wounds have matured. Accurate preoperative assessment and appreciation of the true tissue deficiency, appropriate application of different reconstructive options, and the establishment of the priorities of reconstruction in relation to individual requirements are essential for a successful outcome. In general, functional needs have to be met before attending to aesthetic concerns and priority should be given to restore active before passive function. Different reconstructive options using direct closure, skin grafts, flaps, free tissue transfer, and tissue expansion are discussed.published_or_final_versio

Analysis of recurrence after surgical treatment of advanced laryngeal carcinoma

The pattern of recurrences after surgical treatment of 276 patients with stage T3 and T4 laryngeal carcinoma was reviewed. Nodal recurrence was the commonest site and occurred mainly in patients with supraglottic and transglottic carcinoma. Distant metastasis was the second commonest site of recurrence, and the most distant metastases developed without locoregional recurrence. Local recurrence alone was uncommon in patients treated with primary surgery.published_or_final_versio

Reconstruction after craniofacial trauma

Management of craniofacial trauma has became a sophisticated branch of reconstructive surgery in the last 20 years. New operative techniques and advanced technologies have evolved to allow much better treatment results to be achieved. The general principles of diagnosis and management of craniofacial trauma are discussed. The approach to individual fractures is also highlighted.published_or_final_versio

Short- and medium-term outcomes of accelerated infant growth in a Hong Kong Chinese birth cohort.

1. In a large, population representative,Chinese birth cohort, higher birth weight and rapid growth, particularly at 0-3 months, were associated with higher body mass index (BMI) at 7 years. 2. Boys born heavy who had grown fast had the highest BMI, but rapid growth had the largest impact in lighter-born boys. 3. Rapid growth at 0-3 months or 3-12 months was not associated with a compensatory lower risk of serious infectious morbidity. 4. The ability to grow fast may be an embodiment of good health status, rather than fast growth being causally protective.published_or_final_versio
