Experimental model of peritoneal adhesion formation developing in rats and rabbits as a result of dosed autohemoperitoneum is described. The role of peritoneal macrophages, their microenvironment cells, and cytokines in the development of peritoneal adhesions is demonstrated.

In this work we present a minimal structure-based model of protein diffusional search along local DNA amid protein binding and unbinding events on the DNA, taking into account protein-DNA electrostatic interactions and hydrogen-bonding (HB) interactions or contacts at the interface. We accordingly constructed the protein diffusion-association/dissociation free energy surface and mapped it to 1D as the protein slides along DNA, maintaining the protein-DNA interfacial HB contacts that presumably dictate the DNA sequence information detection. Upon DNA helical path correction, the protein 1D diffusion rates along local DNA can be physically derived to be consistent with experimental measurements.

Background: This preregistered study compares adolescents with mild-to-borderline intellectual disability (MBID) and typically developing (TD) adolescents on their susceptibility to peer influence. To understand why adolescents with MBID are susceptible to peer influence, links with inhibition, Theory of Mind (ToM) and negative interpretation bias are investigated.
Method: We assessed 163 adolescents (111 MBID, 52 TD 14-19 years; 63% boys) using experimental tasks and self- and/or teacher-reports.

Objective: This study aims to evaluate the viability of a hypothesis for selective targeting of skin cancer cells by exploiting the spectral gap with healthy cells using analytical and numerical simulation.
Methods: The spectral gap was first identified using a viscoelastic dynamic model, with the physical and mechanical properties of healthy and cancerous skin cells deduced from previous experimental studies conducted on cell lines. The outcome of the analytical simulation was verified numerically using modal and harmonic analysis.

Hormone replacement therapy (HRT) for postmenopausal syndrome (PMS) carries high risks of undesirable side effects. This study explores irisin as a potential alternative to HRT and investigates the underlying mechanisms. Ovariectomized (OVX) female mice was used as an animal model.

Smartphone-based colorimetric (bio)sensing is a promising alternative to conventional detection equipment for on-site testing, but it is often limited by sensitivity to lighting conditions. These issues are usually avoided using housings with fixed light sources, increasing the cost and complexity of the on-site test, where simplicity, portability, and affordability are a priority. In this study, we demonstrate that careful optimization of color space can significantly boost the performance of smartphone-based colorimetric sensing, enabling housing-free, illumination-invariant detection.
