Enhancing Osteogenesis and Mechanical Properties through Scaffold Design in 3D Printed Bone Substitutes.

In the context of regenerative medicine, the design of scaffolds to possess excellent osteogenesis and appropriate mechanical properties has gained significant attention in bone tissue engineering. In this review, we categorized materials into metallic, inorganic, nonmetallic, organic polymer, and composite materials. This review provides a more integrated and multidimensional analysis of scaffold design for bone tissue engineering.

Ferroptosis combined with photodynamic therapy (PDT) has emerged as a powerful approach to induce cancer cell death by producing and accumulating lethal reactive oxygen species (ROS) in the tumor microenvironment (TME). Despite its efficacy and safety, challenges persist in delivering multiple drugs to the tumor site for enhanced antitumor efficacy and improved tissue targeting. Hence, we designed a method of inducing ferroptosis through laser-mediated and human homologation-specific efficient activation, which is also a ferroptosis therapy with higher safety through ROS-mediated.

Purpose: Local recurrence of prostate cancer (PCa) after radiation therapy (RT) typically occurs at the site of dominant tumor burden, and recent evidence confirms that magnetic resonance imaging (MRI) guided tumor dose escalation improves outcomes. With the emergence of prostate-specific membrane antigen (PSMA) positron emission tomography (PET), we hypothesize that PSMA-PET and MRI may not equally depict the region most at risk of recurrence after RT.
Methods And Materials: Patients with intermediate- to high-risk PCa and MRI plus PSMA-PET performed before RT were identified.
Pitfalls in performing genome-wide association studies on ratio traits.

Insitro, South San Francisco, CA, USA.
Genome-wide association studies (GWAS) are often performed on ratios composed of a numerator trait divided by a denominator trait. Examples include body mass index (BMI) and the waist-to-hip ratio, among many others. Explicitly or implicitly, the goal of forming the ratio is typically to adjust for an association between the numerator and denominator.

Rationale And Objectives: Alzheimer's disease (AD) is the most common pathogenesis of dementia, and mild cognitive impairment (MCI) is considered as the intermediate stage from normal elderly to AD. Early detection of MCI is an essential step for the timely intervention of AD to slow the progression of this disease. Different form previous studies in the whole-brain spontaneous activities, this research aimed to explore the low-frequency amplitude spectrum activities of patients with MCI within the default mode network (DMN), which has been involved in the process of maintaining normal cognitive function.
