In Vitro Assessment of Chitosan-PEG Hydrogels Enriched with MSCs-Exosomes for Enhancing Wound Healing.

Regenerating skin tissue remains a major challenge in medical science, especially due to the risk of scarring and prolonged healing, which becomes even more complicated in people with diabetes. Recent advancements have led to the creation of therapeutic dressings incorporating drug-delivery systems to tackle these issues. Exosomes (Exos) derived from mesenchymal stem cells (MSCs) have gained significant attention for mediating therapy without directly using cells, thanks to their natural anti-inflammatory and tissue repair properties mirroring those of MSCs.

Baicalin nanoemulsion mitigates cisplatin-induced hepatotoxicity by alleviating oxidative stress, inflammation, and restoring cellular integrity.

Cisplatin is a widely used chemotherapeutic agent, but its clinical utility is limited by side effects affecting different systems and organs, including hepatotoxicity in some cases. Baicalin, a flavonoid isolated from Scutellaria baicalensis, possesses antioxidant, anti-inflammatory and hepatoprotective properties, but its low bioavailability limits its therapeutic use. This study aimed to investigate whether a nanoemulsion formulation of baicalin could enhance its efficacy against cisplatin-induced hepatic injury in rats.

Blood cancer prediction model based on deep learning technique.

This paper focuses on improving blood cancer diagnosis using advanced deep learning techniques like ResNetRS50, RegNetX016, AlexNet, Convnext, EfficientNet, Inception_V3, Xception, and VGG19.

PDO screw threads versus fractional CO laser, after subcision, for atrophic acne scar remodelling: a randomized group-based comparative study.

Atrophic acne scars present a significant therapeutic challenge. While subcision with various adjunctive treatments, including fractional CO₂ lasers and polydioxanone (PDO) threads, has been employed for scar remodeling, comparative evidence on their efficacy remains limited. This study aims to compare the clinical efficacy and patient satisfaction between subcision with fractional CO₂ laser and subcision with PDO screw threads in managing atrophic acne scars.

Functions of the Bloom Syndrome Helicase N-terminal Intrinsically Disordered Region.

Bloom Syndrome helicase (Blm) is a RecQ family helicase involved in DNA repair, cell-cycle progression, and development. Pathogenic variants in human BLM cause the autosomal recessive disorder Bloom Syndrome, characterized by predisposition to numerous types of cancer. Prior studies of Drosophila Blm mutants lacking helicase activity or protein have shown sensitivity to DNA damaging agents, defects in repairing DNA double-strand breaks (DSBs), female sterility, and improper segregation of chromosomes in meiosis.

Silymarin nanoparticles counteract cognitive impairment induced by doxorubicin and cyclophosphamide in rats; Insights into mitochondrial dysfunction and Nrf-2/HO-1 axis.

Most cancer patients suffer cognitive impairment following chemotherapy, recognized as "chemobrain". Principally, doxorubicin and cyclophosphamide are frequently utilized conjointly for the treatment of several kinds of tumors. Silymarin was reported to possess anti-inflammatory, antioxidant, and neuroprotective impacts.

Predicting the tumor microenvironment composition and immunotherapy response in non-small cell lung cancer from digital histopathology images.

Immune checkpoint inhibitors (ICI) have become integral to treatment of non-small cell lung cancer (NSCLC). However, reliable biomarkers predictive of immunotherapy efficacy are limited. Here, we introduce HistoTME, a novel weakly supervised deep learning approach to infer the tumor microenvironment (TME) composition directly from histopathology images of NSCLC patients.

Management of Synthol-induced Fibrosis.

Site enhancement oils, such as synthol, are sometimes used by bodybuilders to artificially increase muscle size and shape. However, these injections can lead to severe complications, including fibrosis, infections, and impaired muscle function. We report the case of a 45-year-old male patient who presented with severe fibrosis and recurrent infections in the pectoral region following synthol injections.

Impact of chemical oxygen demand to nitrogen ratio on ANAMMOX bacterial growth in an up-flow anaerobic sludge blanket reactor.

While several studies have investigated the effect of varying carbon-to-nitrogen (C/N) ratios on the ANAMMOX performance, there is still a research gap in illustrating the shift in 16S rRNA gene copy number and functional microbial population during operation. Hence, this study focuses on utilizing a reference gene and target functional genes to demonstrate the synergetic interaction between ANAMMOX, ammonia-oxidizing bacteria (AOB), and nitrite-oxidizing bacteria (NOB), using an up-flow anaerobic sludge blanket (UASB) under different C/N conditions. It was demonstrated that elevating the C/N ratio from 1.

Acid ceramidase controls proteasome inhibitor resistance and is a novel therapeutic target for the treatment of relapsed / refractory multiple myeloma.

Multiple myeloma (MM) patients are often refractory to targeted therapies including proteasome inhibitors (PIs). Here, analysis of RNA sequencing data derived from 672 patients with newly diagnosed or relapsed/refractory disease identified the acid ceramidase, ASAH1, as a key regulator of PI resistance. Genetic or pharmacological blockade of ASAH1 remarkably restored PI sensitivity and protected mice from resistant MM progression in vivo.

Histone deacetylase upregulation of neuropilin-1 in osteosarcoma is essential for pulmonary metastasis.

The lungs represent the most common site of metastasis for osteosarcoma (OS). Despite our advances in developing targeted therapies for treating solid malignancies, broad acting chemotherapies remain the first line treatment for OS. In assaying the efficacy of approved therapeutics for non-OS malignancies, we previously identified the histone deacetylase 1 and 2 (HDAC1 and 2) inhibitor, romidepsin, as effective for the treatment of established lung metastatic OS.
