Relationship between the lateral circumflex femoral vein and the deep femoral artery: Cadaveric study and classification

open access: yesTranslational Research in Anatomy
Background: The lateral circumflex femoral vein is ligated and transected to access the proximal portion of the deep femoral artery during femoral tripod revascularization.

Ubiquitination of ACSL4 by Parkin Suppresses Ferroptosis and Rescues Glucocorticoid‐Induced Bone Loss

open access: yesAdvanced Science, EarlyView.
GCs reduce Parkin, leading to ACSL4 accumulation and PUFA‐phospholipid‐driven ferroptosis in BMSCs, which impairs osteogenesis and promotes adipogenesis, causing GIOP. Parkin restoration (via OE‐Parkin or Parkin‐LNP@DSS6) ubiquitinates and degrades ACSL4, inhibiting ferroptosis, rescuing bone formation, and rescues GIOP bone loss.

Implante de resincronizador cardiaco por vía femoral: Una alternativa para accesos subclavios difíciles Cardiac resynchronization device implantation via the femoral artery: An alternative to difficult subclavian access

open access: yesRevista Colombiana de Cardiología, 2012
Pese a que no hay duda del beneficio de la terapia de resincronización cardiaca, el incremento del uso de esta técnica deja entrever dificultades en el posicionamiento de los electrodos y en particular del electrodo izquierdo.

A Glucose Metabolism‐Modulatory Nanobiohybrid Vaccine Platform Promotes Anti‐Tumor Immunity by Orchestrating Autophagy‐Dependent Cross‐Presentation and H2S‐Enhanced NLRP3 Inflammasome Signaling

open access: yesAdvanced Science, EarlyView.
A nanobiohybrid vaccine was designed by constructing a hydrogen‐bonded organic framework coencapsulated with glucose oxidase (GOx) and tumor antigens. This nanobiohybrid vaccine executed a GOx‐catalyzed enzyme reaction that disrupted glucose metabolism and induced redox imbalance in dendritic cells, leading to autophagy‐dependent antigen cross ...

Virtual Machining of Total Knee Replacement Products Based on Finite Element Analysis (FEA) and Re-Design Optimization by ISO 14243

open access: yesManagement Systems in Production Engineering
This study evaluates the performance of total knee replacement (TKR) components by examining the design, simulation, and machining processes involved. The purpose was to assess the suitability of computer-aided design (CAD) about established standards ...

Pyrazole‐Derived Antibacterial Compounds Effectively Treat Methicillin‐Resistant Staphylococcus Aureus Infections by Inhibiting Aspartate Transcarbamoylase

open access: yesAdvanced Science, EarlyView.
This study unveils a novel antibacterial mechanism against MRSA, in which the compound Py‐27 selectively targets and inhibits aspartate transcarbamoylase (ATCase), a key enzyme in pyrimidine synthesis. This inhibition disrupts DNA replication, induces oxidative damage, leading to potent bactericidal activity.

In Situ Profiling of Nanoscale Strains Uncovers Mechano‐Architectural Predictors of Aging and Osteoarthritis Emergence

open access: yesAdvanced Science, EarlyView.
In situ mechanical loading of osteoarthritis‐prone murine knee joints reveals that spatial alterations in subchondral plate microarchitecture precede cartilage loss and promote a shift from coordinated epiphyseal strain dissipation in healthy joints to focal subchondral strain concentration in osteoarthritis‐prone joints.

The IRE1‐XBP1s Axis Drives Inflammatory Osteolysis by Regulating a 5‐HT Dependent Endogenous Anti‐Autophagy Mechanism

open access: yesAdvanced Science, EarlyView.
A previously unrecognized IRE1‐XBP1s‐Slc6a4 signaling axis links endoplasmic reticulum stress to serotonin metabolism, autophagy, and inflammatory osteoclastogenesis. By promoting intracellular serotonin uptake and reducing endogenous 3‐methyladenine accumulation, this pathway accelerates inflammatory bone destruction and provides a promising ...

YAP1‐Driven Pathogenic Fibro‐Adipogenic Progenitors Secrete IL‐6 and FGF21 to Mediate Muscle‐Bone Crosstalk and Promote Bone Loss

open access: yesAdvanced Science, EarlyView.
Fibro‐adipogenic progenitors (FAPs) in atrophic muscle undergo YAP1‐driven pathogenic activation, secreting IL‐6 and FGF21 as bone‐catabolic myokines that mediate muscle‐bone crosstalk and promote bone loss. Genetic or pharmacological targeting of this YAP1‐FAP‐myokine axis rescues skeletal deterioration, identifying FAP‐derived myokines as therapeutic

The Coronal Angulation of the Femur in Thai Osteoarthritic Knee Patients with Varus Deformity

open access: yesSiriraj Medical Journal, 2020
Objective: To determine the angulation of the distal femoral axis - femoral mechanical axis and the coronal femoral bowing in varus OA knees. This information is necessar, because the routine distal femoral valgus cut can potentially lead to error in ...
