Comparison of compressive strength of a novel hydroxyapatite tack with titanium and resorbable tacks – an in-vitro study

The development of resorbable fixation devices has gained momentum due to limitations associated with titanium systems, including the need for device removal, soft-tissue complications, and uncertain long-term outcomes. This study introduces a novel hydroxyapatite (HA) tack desig...

Stoichiometry-driven electronic heterogeneity in covalent organic frameworks for coupled H2O2 photoproduction and chemoselective fragrance upgrading

Coupling H2O2 photoproduction with value-added organic transformations avoids the sluggish kinetics of water oxidation, yet integrating both processes within one photocatalyst remains challenging. Here, we report stoichiometry-driven electronic heterogeneity in covalent organic f...

Early oseltamivir initiation and influenza outcomes in kidney transplant recipients: a multicenter real-world study

Influenza infection poses a significant clinical threat to kidney transplant recipients due to their immunocompromised status. Although current guidelines recommend early antiviral therapy, real-world evidence supporting the effectiveness of oseltamivir, particularly regarding th...

Electrochemical click chemistry for controlled and localized biosensor surface functionalization

Biosensor performance depends strongly on the properties of the functionalized electrode interface, making robust and controllable surface modification strategies highly desirable. In this work, we investigate electrochemical click chemistry (E-click) as an electrochemically driv...

Effects of Variable-Speed Operation on the Performance and Loss Characteristics of an Industrial Centrifugal Compressor

In this study, the effects of variable-speed operation on the performance and internal flow of an industrial centrifugal compressor were investigated using computational fluid dynamics. Simulations were conducted at 100%, 90%, and 80% of the design rotational speed under identica...

Mechanical-press torrefaction of Napier grass for bio-coke production: effects of temperature and pressure on densification, fuel properties, and CO2 gasification behavior

This study investigated a mechanical-press torrefaction-assisted carbonization route for producing Napier grass-derived bio-coke. Napier grass was first torrefied under mechanical pressure at 280–340 °C and 20–70 MPa, followed by carbonization at 1000 °C. The effects of torrefact...

A tumor microenvironment acid-responsive therapy combining fenton chemistry and chemotherapy via TNF pathway for synergistic and safe lung cancer treatment

Lung cancer is one of the most common malignant tumors, but traditional treatments, particularly chemotherapy, often face significant challenges, including drug resistance and high systemic toxicity. In this study, we developed a novel acid responsive nanoparticle, La₂O₃@PDA/PTX,...

Risk factors for gestational hypertension and preeclampsia: a multivariate logistic regression analysis in a less-developed province in south-central China, 2012–2022

To explore risk factors for gestational hypertension and preeclampsia. Data were obtained from the Maternal Near-Miss Surveillance System in Hunan Province, China, 2012–2022. Multivariate logistic regression analysis (method: Enter, α = 0.05) and odds ratios (ORs) were used to id...

Analysis and optimization of process parameters affecting core-spun ring yarn properties using a soft computing-based approach

This study presents a soft computing-based framework for the analysis, modeling, and optimization of cotton/polyester core-spun yarn properties produced on a ring spinning system. The effects of pre-tension, core multi-filament linear density, twist level, and spindle speed on ya...

Mental health status and its correlates among emerging adults living in the west bank experiencing prolonged conflict: a study on depression, anxiety, war-related stress, and resilience

Emerging adults living in conflict-affected regions are exposed to chronic stressors that may adversely affect their psychological well-being. In the West Bank, prolonged exposure to war, political violence, military escalation, and radical attacks has created a persistent enviro...

Hypothalamic prolactin receptor+ dopaminergic neurons regulate energy metabolism and nociceptive threshold in mice during lactation

Women during lactation undergo significant bone loss and metabolic changes. However, the underlying mechanisms in the brain remain unclear. Herein, we found that prolactin receptor (PRLR)+ neurons in the hypothalamus control lactation physiology and metabolism in mice. Prolactin...

Optimization of Biaxial Tensile Specimens Incorporating Polymer Machinability

고분자 재료의 다축 기계적 거동 평가에는 이축 인장 시험이 필수적이다. 하지만 ISO 16842 표준 시편은 좁은 슬릿 구조로 인해 제작 공정에 제약이 있어 고분자 소재에 적용하기 어렵다. 본 연구에서는 이를 원형 홀 등간격 배열로 대체한 천공 십자형 시편을 제안하였다. 완전요인배치법으로 생성한...

Population-adapted nolla method for dental age estimation in Northwestern Romanian children

Accurate dental age (DA) estimation is essential in pediatric dentistry, orthodontic treatment planning, and forensic practice; however, the applicability of international reference standards varies across populations. This study aimed to evaluate the accuracy of a population-ada...

The missing improvers: Tau pathology, neuroplasticity, and the case for tau-informed patient selection before amyloid immunotherapy

Amyloid immunotherapy with lecanemab and donanemab has been approved on the basis of statistically significant slowing of cognitive and functional decline in early Alzheimer's disease (1,2). Yet clinicians treating individual patients face the everyday challenge of estimating whe...
