Summary: In this study, the multiscale structure, molecular composition, and biomechanics of collagen fibrils in connective tissues of healthy women and POP patients were analyzed. The correlation between these properties and clinical POP quantification scores was established. The study revealed that collagen characteristics change with the progression of POP, suggesting a link between severe prolapse and altered collagen properties. The findings also indicate that the deterioration of the collagen matrix is synchronized with prolapse progression. These results highlight the potential of using non-invasive clinical tests to quantitatively assess collagen abnormalities and guide personalized treatment for POP patients.

Summary: This article discusses the evolution of clinical practice in primary care, from traditional small practices to today's electronic medical records and value-based payment systems. It emphasizes the need to reset expectations regarding current practice structures and patient care expectations in order to meet the evolving demands of patients, society, and practicing internists.

Summary: Cells recognize collagen fibrils as the first step in adherence process. Chicken skin actinidain-hydrolyzed collagen (LASCol) with telopeptides removed causes cells to form spheroids instead of monolayer. LASCol fibrils have looser molecular packing compared to pepsin-hydrolyzed collagen (PepCol) fibrils, promoting cell spheroid formation.

Summary: Using molecular dynamics simulations and experimental studies, it was found that double-fragment peptide fibrils have lower relative beta-sheet content compared to single-fragment peptide fibrils. The morphological differences, such as short protofibrils, elongated, twisted, and rod-like structures, in non-capped and capped double-fragment peptide systems were confirmed through TEM analysis. The differences in Thioflavin T fluorescence lifetime profiles upon fibril binding suggest potential morphological differences in the fibril samples.

Summary: Several degenerative amyloid diseases have no effective treatment and are associated with the formation of protein aggregates and insoluble amyloid fibrils. Developing a reliable and economic screening protocol to identify potential fibril disruptors is important for finding new therapeutic strategies.

Summary: This study reports a new approach using fibrillized collagen microparticles (F-CMPs) as intercellular binders to form hepatocyte-based 3D tissues. Thick and stable tissues were successfully created by mixing these microparticles with hepatocytes, with a thickness of approximately 200 microns. The incorporation of F-CMPs improved cell viability and hepatocyte-specific functions, demonstrating the significance of this method for hepatocyte-based tissue engineering.

Summary: This study investigated the emulsion-based food stabilization mechanism using fish-derived collagen hydrolysate, with CH samples from Pacu skin and Tilapia bones showing excellent emulsifying properties and potential as food stabilizers. The CH samples significantly enhanced the emulsion stability of a drug, retained the emulsion properties of butter and chocolate sauce, and exhibited no cytotoxic effects on leukocytes and Vero cells, indicating promising applications in the food industry. Structural studies revealed a unique quasifibrillar network formed by CH peptides, which contributed to their surface activity and optimal orientation in interacting with multiple phases.

Summary: This study investigated the effects of using acellular dermal matrix (ADM) as a tissue expander cover on dermal changes during tissue expansion. The results showed that using ADM can mitigate disruption in the dermal structure, excessive collagen deposition, and capsule formation, improving the outcomes of tissue expansion.

Summary: The contribution of intrinsic toughening mechanisms on the dynamic fracture behavior of bovine cortical bone is investigated. It is shown that as the heat treatment temperature increases, there is a weak but decreasing trend in fracture toughness, and the mode-II fracture initiation toughness is larger than the mode-I fracture initiation toughness for the 160℃ and 190℃ treated specimens.

Summary: This study investigated the adverse changes in bone quality due to the accumulation of advanced glycation end-products (AGEs) and their influence on fracture mechanics of cortical bone tissue. The results showed that AGE accumulation enhances some pre-and post-yield properties of the tissue, but does not play a role in bone fragility at fall-related loading rates.

Summary: Grounded in hedonic assumptions, this study examined the affective response to resistance training and found that immediate assessment after each set is an effective method. The results also showed that exercisers with different preference and tolerance profiles exhibited distinct patterns of affective response, calling for a differentiated approach to affective regulation.

Summary: This study investigated the relationship between the microscale compressive mechanical properties of bone and mineralized collagen fibril orientation, finding a strong dependence of compressive micromechanical properties on fibril orientation with high anisotropy. It also revealed a transition from softening to hardening behavior at approximately 50 degrees. The combination of methods used provides a reliable way to determine structure-property relationships at the microscale, offering insights into bone quality assessment.

Summary: This study investigates the microstructural damage of cerebral arteries under different loading rates using collagen hybridizing peptide (CHP). The results show that collagen fibrils aligned with the loading direction experience less denaturation at high rates compared to low rates. These findings have important implications for traumatic brain injury and intracranial balloon angioplasty.

Summary: Mammals generally do not regenerate injured organs due to wound contraction during wound healing, which hinders endogenous regeneration mechanisms, leading to scar formation. Engineered treatments like DRT can block wound contraction and promote regeneration instead of scar formation in wound healing.

Summary: This study investigates the influence of collagen fibril orientation, hydration, and interaction on the mechanical properties of bone. The results show that the orientation of collagen fibrils significantly affects the mechanical properties of bone, with longitudinal force providing greater strength compared to perpendicular force. Additionally, the orientation of hydrated and un-hydrated collagen fibrils leads to significant differences in ultimate tensile strength and toughness. Substituting glycine with other amino acids also impacts the mechanical properties and strength of the collagen-hydroxyapatite interface and, consequently, the hydroxyapatite.
