Cost-Effective Laser Powder Bed Fusion of Ti-6Al-4V Grade 5: The Effect of Expanding Powder Size Distribution on Mechanical Performance.

This study aims to assess the feasibility of expanding the powder size distribution (PSD) of Ti-6Al-4V grade 5 powder for LPBF to achieve cost reduction. Parameter optimization to minimize the degradation of mechanical properties due to the expanded particle size distribution was conducted. Mechanical tests for specimens built using optimized parameters revealed minor reductions in strength: 3.

Uncovering potential causal genes for undiagnosed congenital anomalies using an in-house pipeline for trio-based whole-genome sequencing.

Background: Congenital anomalies (CAs) encompass a wide spectrum of structural and functional abnormalities during fetal development, commonly presenting at birth. Identifying the cause of CA is essential for accurate diagnosis and treatment. Using a target-gene approach, genetic variants could be found in certain CA patients.

hsa-mir-483-3p modulates delayed breast cancer recurrence.

Patients with estrogen receptor-positive breast cancer undergoing continuous adjuvant hormone therapy often experience delayed recurrence with tamoxifen use, potentially causing adverse effects. However, the lack of biomarkers hampers patient selection for extended endocrine therapy. This study aimed to elucidate the molecular mechanisms underlying delayed recurrence and identify biomarkers.

The microbial metabolite imidazole propionate dysregulates bone homeostasis by inhibiting AMP-activated protein kinase (AMPK) signaling.

Microbial metabolites provide numerous benefits to the human body but can also contribute to diseases such as obesity, diabetes, cancer, and bone disorders. However, the role of imidazole propionate (ImP), a histidine-derived metabolite produced by the intestinal microbiome, in bone metabolism and the development of osteoporosis is still poorly understood. In this study, we investigated the role of ImP and its underlying mechanisms in regulating bone homeostasis.

Evaluating the efficacy and safety of 2-methoxy-6-methylpyridine: a promising topical agent for gallstone dissolution in a porcine model.

While methyl-tertiary butyl ether (MTBE) remains the sole clinical topical agent for gallstone dissolution, its utility is limited due to side effects, largely stemming from its relatively low boiling point (55°C). In this study, we introduced 2-methoxy-6-methylpyridine (MMP), a novel gallstone-dissolving compound featuring an aromatic moiety and a substantially higher boiling point (156°C), designed to mitigate these side effects. We conducted a comprehensive evaluation of the efficacy and potential toxicities of MMP compared to MTBE using both in vitro and in vivo models.
