Stratification research in the status attainment tradition contends that adolescent educational expectations are a central determinant of educational attainment. Little research, however, has assessed the robustness of the powerful expectations-attainment associations revealed in cross-sectional models. Using data from the National Longitudinal Study of Adolescent to Adult Health to estimate OLS, school fixed effects, and sibling fixed effects models, this study examines the association between adolescent expectations and educational attainment. The analysis reveals that adolescent expectations may play a much smaller role in predicting educational attainment than revealed in cross-sectional models. Point estimates of the association between adolescent expectations and educational attainment from sibling fixed effects models are over 50 percent lower than OLS estimates, suggesting that family-level characteristics confound this relationship. Results from these analyses demonstrate that respondents' educational expectations likely exert less influence on educational attainment than status attainment research would suggest.A novel NIR (near infrared) active photothermal agent, CNTs-PAMAM-Ag2S has been synthesized by covalent grafting of polyamidoamine (PAMAM) to carbon nanotubes (CNTs) and subsequent deposition of Ag2S nanocrystallites. The potential of CNTs-PAMAM-Ag2S as a NIR active photothermal agent was preliminarily accessed by its electronic absorption spectrum measured in UV-vis-NIR region. The CNTs-PAMAM-Ag2S exhibited excellent photothermal effect and photothermal conversion efficiency of 26% under illumination with 980 nm laser, the efficiency was found to be higher than popular gold and copper based photothermal agents. Temperature attained by CNTs-PAMAM-Ag2S during measurement of its photothermal effect was 64.7 °C at 1 g/mL, which far exceeds the temperature tolerance level of cancer cells. So that CNTs-PAMAM-Ag2S could destroy the cancer cells in an effective manner. Furthermore, it was found the linear dependence of photothermal effect of CNTs-PAMAM-Ag2S over its concentration. CNTs-PAMAM-Ag2S possessed excellent stability against photo-bleaching and photo-corrosiveness. In consideration of its outstanding photothermal effect and photothermal conversion efficiency, CNTs-PAMAM-Ag2S could be a promising photothermal agent to employ in future photothermal therapy.Soft-tissue tumors are rare in the pediatric population. First described in 1969 as myxoma of the nerve sheath, the neurothekeoma is a benign tumor lesion with presumable origin in the nerve sheath. It occurs mainly in female children and presents as a mass of slow, subcutaneous growth, asymptomatic and without alteration of the local pigmentation. It is predominantly located in the head, neck, and extremities of the upper limbs. This report presents the case of a 16-year-old male with a tumor mass originating from the nerve sheath in the 4 th left metacarpal, intraosseous, and relapsed after previous surgical resection 2 years before this observation.  https://www.selleckchem.com/products/suzetrigine.html  A marginal resection of the tumor mass was performed on the distal region of the fourth metacarpal, followed by curettage of the proximal phalanx and filling with structural autologous bone graft. The patient maintained a favorable postoperative clinical evolution, without local pain or range of motion limitation in his fingers. Radiologically, a progressive trabecular filling of the proximal phalanx of the fourth metacarpal was observed. At 17 months of follow-up, the patient is asymptomatic and shows no signs of relapse. The description of this case serves to increase the familiarity with this rare pathology, and aid its diagnosis and treatment.The use of cephalomedullary devices has gained popularity in the treatment of proximal femoral fractures. Despite their biomechanical advantages, several complications are well described in the literature. One of these complications, which is rarely reported, is the medial migration of the cephalic screw. The authors present this unusual complication in a case of a long-nail implant, which was treated with removal of the implants as a first step, and posterior osteosynthesis with a locked proximal femur plate as a second step, as well the outcome until fracture consolidation and resolution of the case.Osteoid osteoma is a benign neoplasm commonly found in young men, but that can be found in every age, which affects mainly long bones, clinically characterized by continuous and limiting pain that is relieved by salicylates. It is a small lesion composed of immature osteoid tissue, central hypervascularization and surrounding sclerotic area. Its diagnosis is performed by the clinic and aided by imaging tests, such as common radiography and computed tomography. Radiography shows a central radiolucent lesion and peripheral sclerosis. The biopsy takes place only in cases of diagnostic doubt. Surgical treatment involves resection of the niche, providing greater symptomatic relief, as well as percutaneous techniques. The technique of radioisotope-guided resection has good acceptance in the scientific community for its fast surgical procedure directed to the lesion; however, the percutaneous technique that stands out is radiofrequency ablation. In the present study, all of the patients submitted to the technique presented total improvement of the pain.The donation of bone and tendon tissues is an important source of biological material used in several surgical techniques. The removal of such tissues generates an important aesthetic sequel in the donor that requires limb reconstruction before returning the corpse to the relatives. The technique used by the Banco de Ossos do Paraná (Bone Bank from Paraná), Brazil, employs metal rebar, silicone tubes and nylon clamps to rebuild the limbs, it is easy to perform and has satisfactory aesthetic results.Objective  To evaluate the functional results of patients submitted to reverse shoulder arthroplasty for the treatment of rotator cuff arthropathy refractory to conservative treatment. Methods  A retrospective study of 20 patients (21 shoulders), 17 women (81%) and 3 men (19%), underwent a reverse shoulder arthroplasty between October 2012 and September 2017, for a rotator cuff arthropathy treatment, operated by a single surgeon in a single center. The patients were assessed using the Disabilities of the Arm, Shoulder and Hand (DASH) score, the Short-Form (36) Health Survey (SF-36), the visual analogue scale (VAS) of pain rating, and the University of California - Los Angeles (UCLA) score. The mean age at surgery was of 66 years old (range 55 to 83 years old). The duration of symptoms before surgery was of ∼ 2.5 years (range 12 months to 6 years). The mean follow-up was of 42.4 months (range 19 to 56.7 months). Results  The mean postoperative scores were 18.2 points in DASH; 2 points in EVA, of which 16 (77%) corresponded to mild pain, 4 (18%) to moderate pain, and 1 (5%) to severe pain; 29 points in UCLA, of which 6 patients presented a regular result (28%), 10 patients a good result (48%), and 5 patients an excellent result (24%); and 63 points in the SF-36.
