Nonunion is a major complication in fracture repair and remains a challenge in orthopaedics and trauma surgery. In this study, we aimed to evaluate the effectiveness of treatment of nonunion with a large radial defect using a bone-targeting liposome-encapsulated salvianic acid A (SAA-BTL)-incorporated collagen sponge and further elucidate whether the effects were closely related to histone deacetylase 3 (HDAC 3)-mediated endochondral ossification in nonunion healing process.

Fifteen New Zealand female rabbits were randomly divided into three groups. Segmental radius critical size defects (15 mm) were created via surgery on both the forelimbs of the rabbits. The SAA-BTL/SAA/saline-incorporated collagen sponges were implanted into the defects in the three groups, respectively, for four weeks of treatment. X-ray imaging, micro-computed tomography (CT) analysis, histology, and immunofluorescence analysis (HDAC3, collagen II, VEGFA, and osteocalcin) were performed to determine the effects of the treatments. Inreversed these effects in the HDAC3 knockdown cell model.

SAA-BTL can improve nonunion healing through the regulation of HDAC3-mediated endochondral ossification.

Overexpression of c-Met, or hepatocyte growth factor (HGF) receptor, is commonly observed in tumor biopsies and often associated with poor patient survival, which makes HGF/c-Met pathway an attractive molecular target for cancer therapy. A number of antibody-based therapeutic strategies have been explored to block c-Met or HGF in cancers; however, clinical efficacy has been very limited, indicating that blockade of c-Met signal alone is not sufficient. check details Thus, an alternative approach is to develop an immunotherapy strategy for c-Met-overexpressing cancers. c-Met/CD3 bispecific antibody (BsAb) could bridge CD3-positive T lymphocytes and tumor cells to result in potent tumor cell killing.

A bispecific antibody, BS001, which binds both c-Met and CD3, was generated using a novel BsAb platform. Western blotting and T cells-mediated killing assays were utilized to evaluate the BsAb's effects on cell proliferation, survival and signal transduction in tumor cells. Subcutaneous tumor mouse models were used to analyzby T cells and through inhibition of c-Met signal transduction.
c-Met/CD3 bispecific antibody BS001 exhibited potent anti-tumor activities in vitro and in vivo, which was achieved through two distinguished mechanisms through antibody-mediated tumor cell killing by T cells and through inhibition of c-Met signal transduction.β-thalassemia is caused by mutations in the β-globin gene which diminishes or abolishes β-globin chain production. This reduction causes an imbalance of the α/β-globin chain ratio and contributes to the pathogenesis of the disease. Several approaches to reduce the imbalance of the α/β ratio using several nucleic acid-based technologies such as RNAi, lentiviral mediated gene therapy, splice switching oligonucleotides (SSOs) and gene editing technology have been investigated extensively. These approaches aim to reduce excess free α-globin, either by reducing the α-globin chain, restoring β-globin expression and reactivating γ-globin expression, leading a reduced disease severity, treatment necessity, treatment interval, and disease complications, thus, increasing the life quality of the patients and alleviating economic burden. Therefore, nucleic acid-based therapy might become a potential targeted therapy for β-thalassemia.Here we discuss antibody, cell and gene-based therapies that are currently available and under investigation for both wet and dry age-related macular degeneration (AMD). We initially discuss ocular anatomy, AMD modelling as well as the underlying pathophysiology of AMD. The antibody-based trials which have revolutionised the management of wet AMD are reviewed. The latest concepts in antibody therapy for wet AMD such as the port delivery systems, bispecific antibodies, designed ankyrin repeat protein (DARPINs) and brolucizumab are explored. Furthermore, the antibody-based trials targeting the complement pathway to reduce progression of geographic atrophy (GA) in dry AMD are discussed. Stem cell therapy and gene therapy are novel treatment modalities with no established clinical use in wet or dry AMD. Here, we discuss their efficacy so far in clinical trials. Their benefits and risk in the treatment of both wet and dry AMD are evaluated.
To evaluate the performance and safety of the Extended Depth of Focus Implantable Collamer
Lens (EDOF ICL) for improvement of uncorrected near, intermediate and distance visual acuity in phakic subjects with myopia and presbyopia.

Prospective multicenter study.

Presbyopic subjects who required an EDOF ICL in the range of -0.50 D to -18.00 D, exhibited ≤ 0.75 D refractive astigmatism and required from +1.00 to +2.50 D reading add were implanted bilaterally. Assessments at 6 months included uncorrected near, intermediate and distance visual acuities, defocus curves, contrast sensitivity, responses to the National Eye Institute Refractive Error Quality of Life Questionnaire and a Task Assessment Questionnaire.

A total of 34 subjects completed the study. Investigators targeted emmetropia in all eyes. Mean binocular uncorrected near, intermediate and distance visual acuities measured logMAR -0.01 ± 0.05 (20/20), -0.02 ± 0.08 (20/19) and 0.07 ± 0.10 (20/23), respectively. Mean monocular uncorrected near, ce and satisfaction.
This multicenter, prospective clinical investigation demonstrated the ability of the EDOF ICL to correct myopia and presbyopia, resulting in improvement of uncorrected near, intermediate and distance visual acuity without compromising the quality of vision. The EDOF ICL allowed subjects to perform tasks of daily living without glasses or contact lenses. Subjects reported significant improvements in quality of life with high levels of spectacle independence and satisfaction.
To determine the effect of lifitegrast ophthalmic solution 5% on improving the tear film, biometry/keratometry, and refractive accuracy for dry eye patients scheduled for cataract surgery.

Multicenter, prospective, open-label study of 100 eyes of 100 patients undergoing cataract surgery who had a confirmed diagnosis of dry eye. Patients underwent biometry at baseline and again after a 28-day course of lifitegrast 5% BID. Primary outcome was an improvement in the accuracy of preoperative anterior corneal power measurements at predicting postoperative spherical equivalent (SE) pre- and post-lifitegrast treatment. Secondary outcomes included changes in dry eye symptoms and corneal staining.

The accuracy of the biometry readings for the achieved refractive SE within 0.25 D in 47% and 50% of eyes before and after the initial lifitegrast treatment, respectively; within 0.5 D in 71% and 79% of eyes before and after the initial lifitegrast treatment; and within 0.75 D in 81% and 91% of eyes before and after the initial lifitegrast treatment (p < 0.
