Hand Gesture Interface for Robot Path Definition in Collaborative Applications: Implementation and Comparative Study.

The article explores the possibilities of using hand gestures as a control interface for robotic systems in a collaborative workspace. The development of hand gesture control interfaces has become increasingly important in everyday life as well as professional contexts such as manufacturing processes. We present a system designed to facilitate collaboration between humans and robots in manufacturing processes that require frequent revisions of the robot path and that allows direct definition of the waypoints, which differentiates our system from the existing ones.

Yttrium-90 Radioembolization in the Office-Based Lab.

Purpose: To evaluate the feasibility and benefits of performing yttrium-90 radioembolization in an office-based lab (OBL) compared to a hospital setting.

Materials And Methods: A radioembolization program was established in March 2019 in an OBL that is managed by the radiology department of a tertiary care center. Mapping and treatment angiograms performed in the OBL from March 2019 through January 2020 were compared to mapping and treatment angiograms performed in the hospital during the same time period.

Successful treatment of depressed, distensible acne scars using autologous fibroblasts: a multi-site, prospective, double blind, placebo-controlled clinical trial.

Background: A previous clinical trial evaluating autologous fibroblasts (human dermal) injections for the treatment of facial contour deformities found significantly greater improvements in wrinkle and acne scar appearance than with placebo treatment.

Objective: To compare the efficacy and safety of autologous fibroblast treatment of moderate to severe, depressed, distensible facial acne scars with that of vehicle control.

Methods: This was a randomized multicenter, double-blind, placebo-controlled trial in subjects with bilateral moderate to severe acne scarring; subjects served as their own controls.

A multicenter, double-blind, placebo-controlled trial of autologous fibroblast therapy for the treatment of nasolabial fold wrinkles.

Background: Changes associated with aging are partly due to loss of collagen and elastin. Treatment with autologous fibroblasts grown in culture (azficel-T) can help correct the appearance of aging by replacing lost dermal constituents.

Objective: To demonstrate the safety and effectiveness of autologous fibroblasts in the treatment of nasolabial fold (NLF) wrinkles.

A polydiagnostic approach to the differences in the symptoms of schizophrenia in different cultural and ethnic populations.

This study evaluates the pathoplastic influences of ethnicity and culture on the symptoms of schizophrenia. A sample of 113 schizophrenics was evaluated using the Present State Examination (PSE) and Landmark's Manual for the Assessment of Schizophrenia. The subjects were 57 coloured and 56 black individuals.
