Precision Medicine Assessment of the Radiographic Defect Angle of the Intrabony Defect in Periodontal Lesions by Deep Learning of Bitewing Radiographs.

In dental diagnosis, evaluating the severity of periodontal disease by analyzing the radiographic defect angle of the intrabony defect is essential for effective treatment planning. However, dentists often rely on clinical examinations and manual analysis, which can be time-consuming and labor-intensive. Due to the high recurrence rate of periodontal disease after treatment, accurately evaluating the radiographic defect angle of the intrabony defect is vital for implementing targeted interventions, which can improve treatment outcomes and reduce recurrence.

Conformation-gated binding drives negative cooperativity in ATP:cob(I)alamin Adenosyltransferase for optimized cobalamin handling.

Unlabelled: Vitamin B (cobalamin) is a high-value yet scarce cofactor required for various metabolic processes, making its efficient handling important for maintaining metabolic homeostasis. While the involvement of ATP:cob(I)alamin adenosyltransferases (MMAB) in the synthesis, delivery, and repair of 5'-deoxyadenosylcobalamin (AdoCbl) is well established, the kinetic mechanisms that regulate this process, particularly its negative cooperativity, remain poorly understood. Understanding these mechanisms is key to clarifying how MMAB efficiently uses AdoCbl, prevents resource wastage, and supports bacterial survival in nutrient-limited environments.

High-entropy NASICON-Type LiAlTiZrSnTa(PO) with high electrochemical stability for lithium-ion batteries.

LiAlTi (PO) (LATP) is a promising NASICON-type solid electrolyte for all-solid-state lithium-ion batteries (ASSLIBs) owing to its high ionic conductivity, low cost, and stability in ambient atmosphere. However, the electrochemical stability of LATP suffers upon contact with lithium metals, resulting in a reduction of Ti to Ti in its structure. This limitation necessitates interface modification processes, hindering its use in lithium-ion batteries.

Three-Dimensional Surface Reconstruction for Specular/Diffuse Composite Surfaces.

This paper presents an effective three-dimensional (3D) surface reconstruction technique aimed at profiling composite surfaces with both specular and diffuse reflectance. Three-dimensional measurements based on fringe projection techniques perform well on diffuse reflective surfaces; however, when the measurement targets contain both specular and diffuse components, the efficiency of fringe projection decreases. To address this issue, the proposed technique integrates digital holography into the fringe projection setup, enabling the simultaneous capture of both specular and diffuse reflected light in the same optical path for full-field surface profilometry.

Audiological Features in Patients with Rheumatoid Arthritis: A Systematic Review.

Hearing impairment in patients with rheumatoid arthritis has been underestimated for decades. Rheumatoid arthritis can affect both the middle ear (specifically, the incudomalleolar and incudostapedial joints) and inner ear (including the cochlea and acoustic nerve) simultaneously. Despite ongoing research, consensus on effective treatments for hearing impairment in these patients remains elusive.

Prognostic Value of Neutrophil, Monocyte, Lymphocyte, and Platelet/High-Density Lipoprotein Ratios in Ischemic Heart Disease: An NHANES Analysis.

Reversing Signs of Parkinsonism in a Cell Model Using Mitochondria-Targeted Organoiridium Catalysis.

We report the application of organoiridium complexes as catalytic agents for the detoxification of biogenic reactive aldehyde species (RASP), which are implicated in the pathogenesis of neurodegenerative disorders. We show that Ir complexes functionalized with phosphonium cations localize selectively in the mitochondria and have better cellular retention compared to that of their parent Ir species. In a cell model for Parkinsonism, the mitochondria-targeted iridium catalysts exhibited superior cell protecting abilities and longer-lasting effects (up to 6 d) than conventional RASP scavengers, which failed to be effective beyond 24 h.

Human transporter de-oligomerization regulates copper uptake into cells.

Copper is an essential element involved in various biochemical processes, such as mitochondrial energy production and antioxidant defense, but improper regulation can lead to cellular toxicity and disease. Copper Transporter 1 (CTR1) plays a key role in copper uptake and maintaining cellular copper homeostasis. Although CTR1 endocytosis was previously thought to reduce copper uptake when levels are high, it was unclear how rapid regulation is achieved.

Discovery and biological evaluation of potent 2-trifluoromethyl acrylamide warhead-containing inhibitors of protein disulfide isomerase.

Protein disulfide isomerase (PDI) regulates multiple protein functions by catalyzing the oxidation, reduction, and isomerization of disulfide bonds. The enzyme is considered a potential target for treating thrombosis. We previously developed a potent PDI inhibitor, CPD, which contains the propiolamide as a warhead targeting cysteine residue in PDI.

The relationship between tissue inhibitor of metalloproteinases-1 and KCNJ5 mutation in aldosterone-producing adenoma patients.

KCNJ5 somatic mutations in aldosterone-producing adenoma (APA) are linked to higher left ventricular mass index (LVMI) and worse diastolic function. We previously identified an association between plasma tissue inhibitor of metalloproteinases-1 (TIMP-1) and an aldosterone-induced increase in LVMI and diastolic dysfunction. This study aimed to investigate the association between the presence of KCNJ5 somatic mutation and plasma TIMP-1 in APA patients.
