When a digital hologram is reconstructed, only points located at the reconstruction distance are in focus. We have developed a novel technique for creating an in-focus image of the macroscopic objects encoded in a digital hologram. This extended focused image is created by combining numerical reconstructions with depth information extracted by using our depth-from-focus algorithm. To our knowledge, this is the first technique that creates extended focused images of digital holograms encoding macroscopic objects. We present results for digital holograms containing low- and high-contrast macroscopic objects.

Metal-backed versus all-poly tibia in the original cartier unicompartmental knee arthroplasty: outcomes and survivorship at long-term follow-up.

Arch Orthop Trauma Surg

December 2024

Sezione di Chirurgia Protesica ad Indirizzo Robotico Unità di Traumatologia dello Sport, Fondazione Poliambulanza Istituto Ospedaliero, Brescia, Italy.

Purpose: Unicompartmental knee arthroplasty (UKA) is a viable option for localized osteoarthritis (OA) or avascular osteonecrosis with several advantages over total knee arthroplasty (TKA). UKA implants may feature a tibial component either all-polyethylene (AP) or metal-backed (MB). This study aims to retrospectively compare the clinical outcomes and survivorship of 74 UKAs over 16 years, focusing on comparing the results and survivorship of MB versus AP tibial tray.

Poultry represents a rich source of multiple nutrients. Refrigeration is commonly employed for poultry preservation, although extended storage duration can adversely affect the meat quality. Current research on this topic has focused on the analysis of biochemical indices in chilled goose meat, with limited information on changes in metabolites that influence the quality of the meat during storage.

Diabetes mellitus (DM) is a chronic disease associated with numerous complications, including cardiovascular diseases, nephropathy, and neuropathy. Sodium-glucose cotransporter 2 (SGLT-2) inhibitors, a class of novel antidiabetic agents, have demonstrated promising therapeutic effects beyond glycemic control, with potential benefits extending to the cardiovascular and renal systems. Recently, research has increasingly focused on exploring the potential role of SGLT-2 inhibitors in preventing dementia.

Background/objectives: The COVID-19 pandemic has put nurses under extreme pressure, especially affecting them by significantly increasing their workload and compromising their well-being. The lack of balance between work and personal life has caused greater stress and burnout in these professionals, deteriorating their quality of life and the care they provide. This study aims to synthesize the scientific evidence on the relationship between work-family balance and the perceived quality of life of nurses during the COVID-19 pandemic.

Targeting Reactive Oxygen Species for Diagnosis of Various Diseases.

J Funct Biomater

December 2024

Cardiovascular Institute, Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, MA 02115, USA.

Reactive oxygen species (ROS) are generated predominantly during cellular respiration and play a significant role in signaling within the cell and between cells. However, excessive accumulation of ROS can lead to cellular dysfunction, disease progression, and apoptosis that can lead to organ dysfunction. To overcome the short half-life of ROS and the relatively small amount produced, various imaging methods have been developed, using both endogenous and exogenous means to monitor ROS in disease settings.
