Shape memory polymers (SMPs) induced by heat or water are commonly used candidates for biomedical applications. Shape recovery inevitably leads to a dramatic decrease of Youngs modulus due to the enhanced flexibility of polymer chains at the transition temperature. Herein, we introduced the principle of phase transition-induced stiffening of shape memory metallic alloys (SMAs) to the design of molecular structures for shape memory polyurethane (SMPUs), featuring all hard segments composed main chains that are attached with poly(ethylene glycol) (PEG) dangling side chains.

The frequency-dependent contribution of spectrin, the main cytoskeletal protein of red blood cell (RBC) membrane, to the complex admittance and capacitance of suspended RBCs have revealed two dielectric relaxations, βsp (1.4 MHz) and γ1sp (7 MHz). The strength of these relaxations was related to the ability of RBC membrane to deform. Read More

The increasingly early diagnosis of breast disease and the more widespread use of primary systemic therapy leads to an increasing number of surgeries for non-palpable breast lesions (NPL) in clinical practice. Breast-conserving surgery often requires the use of an image-guided preoperative localization procedure, in which a device is placed within the lesion to be removed to guide the surgeon during surgery. These are patients with small, non-palpable tumors detected in the population screening mammogram, cases with significant reduction of the lesion after neoadjuvant chemotherapy and sometimes it is even necessary to mark axillary lymphadenopathies prior to systemic treatment.

This research aims to expand the knowledge on the level of development of segmental flexibility, to girls aged 7-14 years, who practice synchronized swimming. The study includes 112 girls aged between 7 and 14 years, divided into groups on age, every two years, and on the period of synchronized swimming between 6 months and 42 months. The study focused on three body segments, namely: torso, hip, and shoulder. Read More

Objective: The traditional anterior approach for multilevel severe cervical ossification of the posterior longitudinal ligament (OPLL) is demanding and risky. Recently, a novel surgical procedure-anterior controllable antedisplacement and fusion (ACAF)-was introduced by the authors to deal with these problems and achieve better clinical outcomes. However, to the authors' knowledge, the immediate and long-term biomechanical stability obtained after this procedure has never been evaluated. Read More
