Optimizing approaches for targeted integration of transgenic cassettes by integrase mediated cassette exchange in mouse and human stem cells.

To enable robust expression of transgenes in stem cells, recombinase mediated cassette exchange at safe harbour loci is frequently adopted. The choice of recombinase enzyme is a critical parameter to ensure maximum efficiency and accuracy of the integration event. We have explored the serine recombinase family of site-specific integrases and have directly compared the efficiency of PhiC31, W-beta and Bxb1 integrase for targeted transgene integration at the Gt(ROSA)26Sor locus in mouse embryonic stem cells.

Role of chemokines in aging and age-related diseases.

Chemokines (chemotactic cytokines) play essential roles in developmental process, immune cell trafficking, inflammation, immunity, angiogenesis, cellular homeostasis, aging, neurodegeneration, and tumorigenesis. Chemokines also modulate response to immunotherapy, and consequently influence the therapeutic outcome. The mechanisms underlying these processes are accomplished by interaction of chemokines with their cognate cell surface G protein-coupled receptors (GPCRs) and subsequent cellular signaling pathways.

Rare and risky: a unique case of concurrent chronic pulmonary aspergillosis and lemierre syndrome.

Lemierre Syndrome is a condition that appears to have been overlooked in recent decades in clinical practice, often resulting in death or long-lasting sequelae when left undetected and untreated. Typically, it occurs following an upper respiratory tract infection, often stemming from tonsillitis, leading to thrombosis of the internal jugular vein and subsequent multiple septic emboli. Here, we present a case a 46-year-old patient with the clinical presentation of pneumogenic sepsis.

A review on exploring pyrolysis potential of invasive aquatic plants.

The rapid spread of invasive aquatic plants poses significant ecological and economic challenges, necessitating effective management strategies. Pyrolysis, a thermochemical decomposition process in an oxygen-free environment, offers a promising solution for converting these plant-based biomass sources into biochar. Biochar, produced through the pyrolysis of organic materials in low-oxygen environments, has high carbon content, excellent resistance to degradation, and high aromaticity, making it a valuable resource for various industries, including agriculture, environment, and energy sectors and supports the circular economy.

Preliminary Study on Multi-Scale Modeling of Asphalt Materials: Evaluation of Material Behavior through an RVE-Based Approach.

This study employs a microstructure-based finite element modeling approach to understand the mechanical behavior of asphalt mixtures across different length scales. Specifically, this work aims to develop a multi-scale modeling approach employing representative volume elements (RVEs) of optimal size; this is a key issue in asphalt modeling for high-fidelity fracture modeling of heterogeneous asphalt mixtures. To determine the optimal RVE size, a convergence analysis of homogenized elastic properties is conducted using two types of RVEs, one made with polydisperse spherical inclusions, and another made with polydisperse truncated cylindrical inclusions, each aligned with the American Association of State Highway and Transportation Official's maximum density gradation curve for a 12.

Luteolin: A promising modulator of apoptosis and survival signaling in liver cancer.

Due to the increasing incidence of cancer and the difficulties in determining the safety profile of existing therapeutic approaches, cancer research has recently become heavily involved in the search for new therapeutic approaches. The therapeutic significance of natural substances, especially flavonoids, against the onset and progression of cancer has been emphasized in traditional food-based medicine. Interestingly, the flavone luteolin possesses biological effects that have been linked to its anti-inflammatory, antioxidant, and anticancer effects.

The long noncoding RNA (LINC-RBE) expression in testicular cells is associated with aging of the rat.

Long noncoding RNAs (lncRNAs) are important regulatory biomolecules responsible for many cellular processes. The aging of mammals is manifested by a slow and gradual decline of physiological functions after adulthood, progressively resulting in age-related diseases. Testis comprises different cell-types with defined functions for producing haploid gametes and androgens in males, contributing gene-pool to the next generation with genetic variations to species for evolutionary advantage.

Dendritic Cells and the Establishment of Fetomaternal Tolerance for Successful Human Pregnancy.

Pregnancy is a remarkable event where the semi-allogeneic fetus develops in the mother's uterus, despite genetic and immunological differences. The antigen handling and processing at the maternal-fetal interface during pregnancy appear to be crucial for the adaptation of the maternal immune system and for tolerance to the developing fetus and placenta. Maternal antigen-presenting cells (APCs), such as macrophages (Mφs) and dendritic cells (DCs), are present at the maternal-fetal interface throughout pregnancy and are believed to play a crucial role in this process.

Effects of the multiscale porosity of decellularized platelet-rich fibrin-loaded zinc-doped magnesium phosphate scaffolds in bone regeneration.

In recent years, metallic ion-doped magnesium phosphate (MgP)-based degradable bioceramics have emerged as alternative bone substitute materials owing to their excellent biocompatibility, bone-forming ability, bioactivity, and controlled degradability. Conversely, incorporating a biomolecule such as decellularized platelet-rich fibrin (d-PRF) on scaffolds has certain advantages for bone tissue regeneration, particularly in enhanced osteogenesis and angiogenesis. The present study focuses on the impact of d-PRF-loaded multiscale porous zinc-doped magnesium phosphate (Zn-MgP) scaffolds on biodegradability, biocompatibility, and bone regeneration.
