Phytic acid-loaded polyvinyl alcohol hydrogel promotes wound healing of injured corneal epithelium through inhibiting ferroptosis.

As the important barrier of intraocular tissue, cornea is easy to suffer various kinds of injuries. Among them, acute alkali burn is a thorny ophthalmic emergency event, which can lead to corneal persistent epithelial defects, ulcers, and even perforation. Ferroptosis, a mode of regulatory cell death, has been found to play a key role in the process of corneal alkali burn, of which lipid peroxidation and intracellular iron levels are considered to be the possible therapeutic targets.

Ferroelectric-defined reconfigurable homojunctions for in-memory sensing and computing.

Recently, the increasing demand for data-centric applications is driving the elimination of image sensing, memory and computing unit interface, thus promising for latency- and energy-strict applications. Although dedicated electronic hardware has inspired the development of in-memory computing and in-sensor computing, folding the entire signal chain into one device remains challenging. Here an in-memory sensing and computing architecture is demonstrated using ferroelectric-defined reconfigurable two-dimensional photodiode arrays.

A thin film comprising silk peptide and cellulose nanofibrils implanting on the electrospun poly(lactic acid) fibrous scaffolds for biomedical reconstruction.

Conjunctival reconstruction using biocompatible polymers constitutes an effective treatment for conjunctival scarring and associated visual impairment. In this work, a thin film comprising silk peptide (SP), cellulose nanofibrils (CNF) and Ag nanoparticles (AgNPs) that implanted on the poly(lactic acid) (PLA) electrospun fibrous membranes (EFMs) was designed for biomedical reconstruction. SP and CNF as thin films can improve the surface hydrophilicity of the as-prepared scaffolds, which synergistically enhanced the biocompatibility.

Downregulation of VPS13C promotes cisplatin resistance in cervical cancer by upregulating GSTP1.

Cisplatin resistance remains a major obstacle limiting the effectiveness of chemotherapy in cervical cancer. However, the underlying mechanism of cisplatin resistance is still unclear. In this study, we demonstrate that vacuolar protein sorting 13 homolog C (VPS13C) deficiency promotes cisplatin resistance in cervical cancer.

SETD8, a frequently mutated gene in cervical cancer, enhances cisplatin sensitivity by impairing DNA repair.

Background: Cisplatin is commonly used to treat cervical cancer while drug resistance limits its effectiveness. There is an urgent need to identify strategies that increase cisplatin sensitivity and improve the outcomes of chemotherapy.

Results: We performed whole exome sequencing (WES) of 156 cervical cancer tissues to assess genomic features related to platinum-based chemoresistance.

Enhanced adipose-derived stem cells with IGF-1-modified mRNA promote wound healing following corneal injury.

The cornea serves as an important barrier structure to the eyeball and is vulnerable to injuries, which may lead to scarring and blindness if not treated promptly. To explore an effective treatment that could achieve multi-dimensional repair of the injured cornea, the study herein innovatively combined modified mRNA (modRNA) technologies with adipose-derived mesenchymal stem cells (ADSCs) therapy, and applied IGF-1 modRNA (modIGF1)-engineered ADSCs (ADSC) to alkali-burned corneas in mice. The therapeutic results showed that ADSC treatment could achieve the most extensive recovery of corneal morphology and function when compared not only with simple ADSCs but also IGF-1 protein eyedrops, which was reflected by the healing of corneal epithelium and limbus, the inhibition of corneal stromal fibrosis, angiogenesis and lymphangiogenesis, and also the repair of corneal nerves.

Knockdown of PRKD2 Enhances Chemotherapy Sensitivity in Cervical Cancer the TP53/CDKN1A Pathway.

Background: Chemotherapy is the common treatment for cervical cancer, and the occurrence of drug resistance seriously affects the therapeutic effect of cervical cancer. Our previous study found that PRKD2 mutations occurred only in cervical cancer patients with chemotherapy resistance. However, the relationship between PRKD2 and drug resistance of cervical cancer remains unknown.

Direct oral mucosal epithelial transplantation supplies stem cells and promotes corneal wound healing to treat refractory persistent corneal epithelial defects.

Persistent corneal epithelial defects (PED) can lead to irreversible blindness, seriously affecting the social function and life quality of these patients. When it comes to refractory PED, such as limbal stem cell deficiency (LSCD), that does not respond to standard managements, stem cell therapy is an ideal method. Oral mucosal epithelium (OME) abundant with stem cells within the base, is a promising autologous biomaterial, with much resemblance to corneal epithelial structures.

and Properties of an Injectable Hydrogel Derived From Acellular Ear Cartilage Extracellular Matrix.

Extracellular matrix (ECM) hydrogels provide advantages such as injectability, the ability to fill an irregularly shaped space, and the adequate bioactivity of native matrix. In this study, we developed decellularized cartilage ECM (dcECM) hydrogels from porcine ears innovatively via the main method of enzymatic digestion and verified good biocompatible properties of dcECM hydrogels to deliver chondrocytes and form subcutaneous cartilage . The scanning electron microscopy and turbidimetric gelation kinetics were used to characterize the material properties and gelation kinetics of the dcECM hydrogels.

Insight into levofloxacin loaded biocompatible electrospun scaffolds for their potential as conjunctival substitutes.

The rehabilitation of visual acuity with severe conjunctival fibrosis depends on ocular reconstruction with suitable conjunctival substitutes. In this study, we have developed poly(lactic acid) (PLA) electrospun nanofibrous membranes (EFMs) surface coated by cellulose nanofibrils (CNF) and/or silk peptide (SP). The CNF coating improved the hydrophilicity and the SP coating proliferated conjunctival epithelial cells (CjECs).

A Fifteen-Gene Classifier to Predict Neoadjuvant Chemotherapy Responses in Patients with Stage IB to IIB Squamous Cervical Cancer.

Neoadjuvant chemotherapy (NACT) remains an attractive alternative for controlling locally advanced cervical cancer. However, approximately 15-34% of women do not respond to induction therapy. To develop a risk stratification tool, 56 patients with stage IB-IIB cervical cancer are included in 2 research centers from the discovery cohort.

Subconjunctival Injection of Regulatory T Cells Potentiates Corneal Healing Via Orchestrating Inflammation and Tissue Repair After Acute Alkali Burn.

Purpose: This study aimed to investigate the therapeutic effects and underlying mechanisms of locally delivered regulatory T cells (Tregs) on acute corneal wound healing after alkali burn.

Methods: After corneal alkali burn, the mice were injected subconjunctivally with regulatory T cells (Tregs) isolated from syngeneic mice. The wound healing process was monitored by clinical manifestation, flow cytometry, and enzyme-linked immunosorbent assay (ELISA).

A systematic comparison of the anti-tumoural activity and toxicity of the three Adv-TKs.

Adenovirus 5 vectors, known respectively as, the first generation, second generation and oncolytic adenovirus, have been studied extensively in preclinical and clinical trials. However, hitherto few systemic evaluations of the efficacy and toxicity of these adenoviral vectors that have reflected the vertical history of adenovirus based cancer gene therapy strategies have been undertaken. This study has chosen Adv-TK, the well-established adjuvant treatment in cancer, and compared its efficacy and safety with those of the two newly synthesized oncolytic adenovirus vectors encoding the HSV-TK gene, namely M7 and M8.

Abrogation of constitutive Stat3 activity circumvents cisplatin resistant ovarian cancer.

The aim of the present study was to investigate the role of Stat3 in cisplatin resistant ovarian cancer. It was first demonstrated that higher activated Stat3 was detected in cisplatin-resistant ovarian cancer cell lines. To provide evidence that supported the hypothesis that phosphorylated-Stat3 expression may promote cisplatin resistance, ectopic Stat3 was expressed by IL-6 stimulation that partially abrogates Stat3, as opposed to the knock-down of Stat3 by specific siRNA that restores cisplatin sensitivity against ovarian cancer cells.
