Epidemiological variations and trends in glaucoma burden in the Belt and Road countries.

Background: Analyzing the glaucoma burden in "Belt and Road" (B&R) countries based on age, gender, and risk factors from 1990 to 2019 in order to provide evidence for future prevention strategies.

Methods: We applied global burden of disease(GBD) 2019 to compare glaucoma prevalence and Years lived with disabilities (YLDs) from 1990 to 2019 in the B&R countries. Trends of disease burden between 1990 and 2019 were evaluated using the average annual percent change and the 95% uncertainty interval (UI) were reported.

Uppermost global tree elevations are primarily limited by low temperature or insufficient moisture.

The impact of anthropogenic global warming has induced significant upward dispersal of trees to higher elevations at alpine treelines. Assessing vertical deviation from current uppermost tree distributions to potential treeline positions is crucial for understanding ecosystem responses to evolving global climate. However, due to data resolution constraints and research scale limitation, comprehending the global pattern of alpine treeline elevations and driving factors remains challenging.

Hydrogel-mediated tumor T cell infiltration and immune evasion to reinforce cancer immunotherapy.

Cancer immunotherapy has received increasing attention in tumor therapy. However, insufficient infiltration of T cells and over-expressed PD-L1 checkpoint in tumor cells severely impede cancer immunotherapy. Here, an injectable hydrogel was designed to reinforce T cell infiltration and inactivate PD-L1 for powerful cancer immunotherapy.

Triazine herbicide reduced the toxicity of the harmful dinoflagellate Karenia mikimotoi by impairing its photosynthetic systems.

Triazine herbicides are common contaminants in coastal waters, and they are recognized as inhibitors of photosystem II, causing significant hinderance to the growth and reproduction of phytoplankton. However, the influence of these herbicides on microalgal toxin production remains unclear. This study aimed to examine this relationship by conducting a comprehensive physiological and 4D label-free quantitative proteomic analysis on the harmful dinoflagellate Karenia mikimotoi in the presence of the triazine herbicide dipropetryn.

Variation in intracellular polyphosphate and associated gene expression in response to different phosphorus conditions in the dinoflagellate Karenia mikimotoi.

Polyphosphate (polyP) has long been recognized as a crucial intracellular reservoir for phosphorus in microorganisms. However, the dynamics of polyP and its regulatory mechanism in eukaryotic phytoplankton in response to variations in external phosphorus conditions remain poorly understood. A comprehensive investigation was conducted to examine the intracellular polyP-associated metabolic response of the dinoflagellate Karenia mikimotoi, a harmful algal bloom species, through integrated physiological, biochemical, and transcriptional analyses under varying external phosphorus conditions.

A single-shot prophylactic tumor vaccine enabled by an injectable biomembrane hydrogel.

Prophylactic tumor vaccines hold great promise against tumor occurrence. However, their clinical efficacy remains low due to inadequate activation of strong-sustainable immunity. Herein, a biomembrane hydrogel was designed as a powerful single-shot prophylactic tumor vaccine.

Tumor lysates-constructed hydrogel to potentiate tumor immunotherapy.

T cell-based immunotherapy (TCBI) is an emerging approach to combat tumors. However, the outcome of TCBI is still far from satisfaction clinically, owing to stumbling blocks from insufficient immunogenicity, T cell exhaustion and immune evasion from programmed death-1/programmed death-ligand 1 (PD-1/PD-L1) pathway. Herein, an injectable tumor lysates-constructed hydrogel is reported to address these issues.

Pulsed Ultrasound-Mediated Enhancement on Transscleral and Transconjunctival Fluorescein Sodium Delivery to Rabbit Eye .

To investigate the efficacy and safety of pulsed ultrasound (PUS) in enhancing fluorescein sodium (NaF) transport to the rabbit eye through the transscleral and transconjunctival routes . PUS and NaF were applied onto the supratemporal sclera/conjunctiva of healthy rabbit eyes. PUS (1 MHz, 2.

7,8-Dihydroxiflavone protects retinal ganglion cells and promotes axonal regeneration through TrkB signaling pathway followed by AKT and ERK activation.

The aim of this study was to investigate the effects of 7,8-dihydroxyflavone (7,8-DHF) in protecting retinal ganglion cells (RGCs) and promoting axonal regeneration, and to explore its potential molecular mechanisms. We used three-dimensional retinal culture system and optic nerve crush (ONC) rat models in this study. The pro-axonal regenerative effect of 7,8-DHF was determined with light microscopy observation and immunofluorescence staining of Thy1.

A photodynamic-mediated glutamine metabolic intervention nanodrug for triple negative breast cancer therapy.

"Glutamine addiction" is a unique feature of triple negative breast cancer (TNBC), which has a higher demand for glutamine and is more susceptible to glutamine depletion. Glutamine can be hydrolyzed to glutamate by glutaminase (GLS) for synthesis of glutathione (GSH), which is an important downstream of glutamine metabolic pathways in accelerating TNBC proliferation. Consequently, glutamine metabolic intervention suggests potential therapeutic effects against TNBC.

Radiotherapy-mediated redox homeostasis-controllable nanomedicine for enhanced ferroptosis sensitivity in tumor therapy.

Ferroptosis has received increasing attentions in cancer therapy owing to its unique advantages over apoptosis. However, ferroptosis is governed by the efficiency of reactive oxygen species (ROS) production and the tumor cell antioxidant microenvironment that compromises therapeutic efficacy of ferroptosis. It is of great significance to develop a strategy that can both achieve high-efficiency ROS production and modulate tumor cell antioxidant microenvironment to amplify ferroptosis.

7,8-Dihydroxyflavone Simultaneously Provides Neuroprotection of Retinal Explants and Proangiogenesis of Human Umbilical Vein Endothelial Cells via the Tropomyosin-Related Kinase Receptor B Signaling Pathway .

This study aimed to investigate the simultaneous neuroprotective and proangiogenic effects of 7,8-dihydroxyflavone (7,8-DHF) and explore the potential underlying molecular mechanisms. A coculture system of rat retinal explants and human umbilical vein endothelial cells (HUVECs) was established to determine the optimal concentration of 7,8-DHF, promoting neurite regeneration and HUVEC proliferation. Subsequently, the neuroprotective effect, proangiogenesis properties, and action mechanism of 7,8-DHF at an optimal concentration were investigated.

An Injectable Hydrogel to Modulate T Cells for Cancer Immunotherapy.

T cell exhaustion caused by mitochondrial dysfunction is the major obstacle of T cells-based cancer immunotherapy. Besides exhausted T cells, the insufficient major histocompatibility complex class I (MHC I) on tumor cells leads to inefficient T cell recognition of tumor cells, compromising therapeutic efficacy. Therapeutic platform to regulate T cell exhaustion and MHC I expression for boosting T cells-based cancer immunotherapy has not been realized up to date.

A modified fabrication procedure of retinal explant and optimized formulation of culture medium in a three-dimensional retinal culture system.

Background: Three-dimensional culture system of retinal explant is commonly used to study retinal ganglion cell (RGC) axon regeneration in vitro. The retinal explants fabricated by traditional procedure in culture system, however, are usually too small (merely 0.5 × 0.
