Polyurethane Foams From a Triblock Copolymer Polyol With CO2‐Derived, High‐Tg Polycarbonate Segments

Journal of Applied Polymer Science, EarlyView.
Polyurethane foam (PUF) properties are tuned by incorporating polyol with 0–15 wt% CO2‐derived poly(cyclohexene carbonate) (PCHC) segments (Tg = 104°C). Network PUFs are synthesized using CO2‐derived triblock copolymer polyol with PCHC hard segments and a polycaprolactone soft segment.

Barrier Properties and Crystalline Structure of Biowax‐Containing Water‐Based Polymer Dispersions Under Different Processing Conditions

Journal of Applied Polymer Science, EarlyView.
This study investigates the nanoscale structures of biowax materials using the wide‐angle x‐ray scattering method. The biowaxes are combined with water‐based polymer dispersions to create barrier coatings for fiber‐based food packaging materials.

Diol Chain‐Length Effects in Adipate and Succinate Polyesters for Thermoplastic Polyurethanes

Journal of Applied Polymer Science, EarlyView.
This study examines 20 aliphatic polyesters as soft segments for thermoplastic polyurethanes (TPU), synthesized from adipic or succinic acid and diols (C2, C3, C4, C5, and C6). A pronounced odd‐even effect shows that even diols crystallize, while odd diols remain amorphous.

Biomechanical strain patterns in Meckel's cartilage underlie mandibular variation in FGFR2 mouse models

The Anatomical Record, EarlyView.
Abstract Sequence variations in fibroblast growth factor receptor 2 (FGFR2) are associated with craniosynostosis syndromes, disrupting craniofacial development, yet early mandibular alterations remain poorly characterized. This study examined Meckel's cartilage (MC) and mandibular morphology in mouse models of Apert (Fgfr2+/P253R) and Crouzon ...

Cable Reinforcement Combined With Biologic Tuberoplasty Restores Muscle Forces and Scapular Strain in an Irreparable Rotator Cuff Tear Model: A Cadaveric Study

Arthroscopy, EarlyView.
Purpose To investigate the biomechanical impact of an irreparable rotator cuff tear and compare the isolated and combined effects of rotator cable reconstruction (CR) and biologic tuberoplasty (BioTB). Methods Eight cadaveric shoulders were tested using an ex vivo dynamic shoulder simulator in forward flexion (FF) and scapular plane abduction (SPA ...

Surgical Technique for Arthroscopic Rotator Cuff Repair With All‐Polyester Patch Augmentation

Arthroscopy Techniques, EarlyView.
Abstract Rotator cuff repair failure remains a challenging problem, particularly in the setting of poor tendon quality or revision surgery. Patch augmentation has been introduced to reinforce repair constructs and improve healing rates, but many biologic and synthetic materials introduce drawbacks such as inflammatory response, increased bulk, donor ...

Arthroscopic Suture‐Only Intra‐articular Soft‐Tissue Long‐Head Biceps Tenodesis to the Rotator Cuff

Arthroscopy Techniques, EarlyView.
Abstract Pathology of the long head of the biceps tendon (LHBT) is a prevalent source of shoulder pain and is often concomitant with rotator cuff diseases. Various treatment modalities exist for addressing this condition, including surgical approaches, anatomical sites for tenodesis fixation, and types of fixation devices employed.
