Study Design: Retrospective cohort study.

Objective: Frailty is defined as a state of minimal "physiologic reserve." The modified 5 factor frailty index (mFI-5) is a recently proposed metric for assessing frailty and has been previously studied as a predictor of morbidity and mortality.

Hepatitis C virus (HCV) is a major public health concern, and the development of an effective HCV vaccine plays an important role in the effort to prevent new infections. Supramolecular co-assembly and co-presentation of the HCV envelope E1E2 heterodimer complex and core protein presents an attractive vaccine design strategy for achieving effective humoral and cellular immunity. With this objective, the two antigens were non-covalently assembled with an immunostimulant (TLR 7/8 agonist) into virus-mimicking polymer nanocomplexes (VMPNs) using a biodegradable synthetic polyphosphazene delivery vehicle.

The cervical spine ligaments, including the anterior longitudinal ligament (ALL) and posterior longitudinal ligament (PLL), play a key role in maintaining spinal stability by limiting excessive movements. This study investigates how ageing affects the mechanical properties of these ligaments. We analysed 33 samples from 12 human cervical spines (15 ALL, 18 PLL), averaging data from the same donors for independent analysis, resulting in 18 final samples (8 ALL, 10 PLL).

The Lateral Collateral Ligament (LCL), one of the four major ligaments in the knee joint, resides on the outer aspect of the knee. It forms a vital connection between the femur and the fibula. The LCL's primary role is to provide stability against Varus forces, safeguarding the knee from undue rotation and tibial displacement.

Objective: The Heat Shock Protein 70 (HSP70) family is a highly conserved group of molecular chaperones essential for maintaining cellular homeostasis. These proteins are necessary for protein folding, assembly, and degradation and involve cell recovery from stress conditions. HSP70 proteins are upregulated in response to heat shock, oxidative stress, and pathogenic infections.
