Ultraviolet (UV) light is the most common cause of radiation injury to the eye which in acute exposure causes photokeratitis and photoconjunctivitis. After a whole day exposure to the sun on the Mediteranian coast patient presented with mixed conjunctival injection, chemosis, edematous corneal epithelium with superficially present fluoresceine positive small pinpoint defects. Epithelial bullous changes, circular stromal infiltration in the middle stromal perifery and reduction of corneal transparency were more pronounced on the left eye. After treatment moderate conjunctival injection remained together with circular stromal infiltration in the middle perifery, corneas were transparent, epithelialised and fluorescein negative. Anterior chambers and lenses were clear. One month after patient regained bilateral visual acuity of 1.0. To our kownledge, this case shows for the first time connection between acute ultraviolet radiation exposure and persistent circular stromal infiltration in the middle corneal perifery in humans.

Extracellular vesicles (EV) have emerged as promising cell-free therapeutics in regenerative medicine. However, translating primary cell line-derived EV to clinical applications requires large-scale manufacturing and several challenges, such as replicative senescence, donor heterogeneity, and genetic instability. To address these limitations, we used a reprogramming approach to generate human induced pluripotent stem cells (hiPSC) from the young source of cord blood mesenchymal stem/stromal cells (CBMSC).

Human thymic stromal lymphopoietin (TSLP) is a pro-inflammatory cytokine located at the top of inflammatory cascade that makes it a promising therapeutic target in allergic asthma. The cell surface receptor of TSLP is a heterodimer consisting of a TSLP receptor (TSLPR) and an interleukin-17 receptor α (IL-7Rα). The TSLPR subunit should be first added to the free TSLP to form a TSLPR/TSLP pre-complex, which further recruits the IL-7Rα subunit to obtain the final TSLPR/IL-7Rα/TSLP complex.

Imatinib (Ima), as a commonly used anticancer drug for the clinical treatment of leukemia and gastrointestinal mesenchymal stromal tumour, requires timely monitoring of patients' blood concentration to ensure efficacy while reducing complications and achieving precision medicine due to its narrow therapeutic window (1-5 μM) and the varying sensitivity and resistance of different patients to Ima. However, traditional assays are slow and cumbersome, so improved and innovative platforms for monitoring Ima in the clinic are necessary. In this work, a nanoporous electrochemical aptamer-based (E-AB) sensor was designed for the detection of Ima and imatinib mesylate (Ima-Mes) in blood.

Recent evidence has demonstrated that abnormal expression and regulation of circular RNA (circRNAs) are implicated in the development and progression of various tumors. The aim of this study was to investigate the effects of circ_SMA4 in Gastrointestinal Stromal Tumors (GISTs) malignant progression. Human circRNAs microarray analysis was conducted to identify differentially expressed (DE) circRNAs in GISTs.

In this study, a novel customized corneal cross-linking (CXL) treatment is explored that utilizes microneedles (MNs) for targeted riboflavin (RF) administration prior to the CXL procedure. Unlike the conventional "one-size-fits-all" approach, this protocol offers an option for more precise and efficacious treatment. To simulate a customized corneal crosslinking technique, four distinct microneedle (MN) molds designs, including circular, semi-circular, annular and butterfly shaped, are crafted for loading an optimized RF-hyaluronic acid solution and for the subsequent fabrication of MN arrays with varying morphologies.
