Facial volume loss has become widely accepted as one of the contributing factors in global facial aging. Some have even suggested that bony, muscular, fatty, and dermal/epidermal changes are more integral in the aging process than gravitational influence. Although detractors of autologous fat transfer persist, facial autologous fat transfer has become widely utilized as one option for volume restoration. Various techniques in harvesting, processing, and injecting autologous fat have been debated at length without clear guidelines emerging to maximize outcomes. This article aims to present one surgeon's experience in successful fat grafting philosophy and technique. Areas covered will include preparation, harvesting, processing, and injection techniques. The injection techniques are organized by facial region and into the general philosophy and thinking regarding the facial region as well as the specific technique that has been utilized over 7 years and hundreds of successful procedures.

Malignant mesenchymal tumors are a diverse group of aggressive cancers originating from mesenchymal cells in connective tissues such as bone, muscle, cartilage, and fat. These tumors often invade surrounding tissues and metastasize to distant organs, posing significant treatment challenges. Among them, malignant mesenchymal tumors located in the distal femur are particularly rare, with limited reports detailing effective surgical and functional reconstruction strategies following wide resection.

The quality of bovine colostrum, primarily determined by IgG concentration, is essential for the transfer of passive immunity and the development of the gastrointestinal tract in neonates. High IgG concentration in bovine colostrum (BC) is pivotal for the calf at first meal; however, while neonates often refuse to voluntarily drink the recommended amount of BC in the first hours of life, the dam frequently fails to produce a sufficient volume of colostrum at first milking. This study seeks to estimate the h of colostrum yield (CY) and its genetic correlations with total Ig, IgG, protein, and fat concentrations for the first time in the Italian Holstein population.

Pickering emulsions (PEs) of natural plant proteins enriched in fat-soluble components are gaining consumer interest for healthier and sustainable products. The aim of this study is to prepare PEs for stabilizing almond protein isolated (API) particles loaded with astaxanthin using ultrasound technology. The loose structure of the API at pH levels of 3 and 12, with contact angles of 68.

Autologous fat grafting is a widely used technique in plastic and reconstructive surgery, but its efficacy is often limited by the poor survival rate of transplanted adipose tissue. This study aims to enhance the survival of fat grafts by investigating the role of thymosin beta-4 (Tβ4) in facilitating mitochondrial transfer from adipose-derived stem cells (ADSCs) to adipocytes and newly formed blood vessels within the grafts via tunneling nanotubes (TNTs). We demonstrate that Tβ4 upregulates the Rac/F-actin pathway, leading to an increased formation of TNTs and subsequent transfer of mitochondria from ADSCs.
