Artificial Cornea Substitute Based on Hydrogel Skeletons with Natural Stromal Hierarchical Structure and Extracellular Matrix for Sutureless Transplantation

open access: yesAdvanced Science, EarlyView.
Humanized corneal stroma‐like adhesive patches (HCSPs) are developed for lamellar keratoplasty and corneal perforation repair. HCSPs exhibit histological, optical, and biomechanical characteristics similar to those of the natural cornea, with improved wet tissue adhesion, anti‐degradation, and anti‐swelling capabilities compared to conventional tissue ...

Chemical characteristics and source apportionment of particulate matter (PM2.5) in Dammam, Saudi Arabia: Impact of dust storms

open access: yesAtmospheric Environment: X, 2022
Atmospheric particulate matter (PM) is known to be harmful to human and environmental health, with factors including particle size and composition thought to be key drivers of toxicity. Understanding the composition and hence sources of PM is critical to

Application of a Self-Organizing State Space Model to the Leonid Meteor Storm in 2001 [PDF]

open access: yes2003, PASJ, 55, 535, 2012
The Leonids show meteor storms in a period of 33 years, and known as one of the most active meteor showers. It has recently shown a meteor stream consisting of several narrow dust trails made by meteoroids ejected from a parent comet. Hence, an analysis of the temporal behavior of the meteor flux is important to study the structure of the trails ...

In Vivo Reprogramming of Tissue‐Derived Extracellular Vesicles for Treating Chronic Tissue Injury Through Metabolic Engineering

open access: yesAdvanced Science, EarlyView.
Inspired by exercise‐induced metabolic rewiring and EV secretion, this study shows that in vivo metabolic engineering strategy can reprogram EV secretion pattern and simultaneously attenuate multiple tissue injury in CKD status, highlighting that it is a potential strategy for treating diverse chronic diseases.

Rise in Mid-Tropospheric Temperature Trend (MSU/AMSU 1978–2022) over the Tibet and Eastern Himalayas

open access: yesApplied Sciences, 2023
The high-altitude Hindu Kush-Himalayan region (HKH, average ~5 km from msl) and the adjacent Indo-Gangetic plains (IG plains, ~0–250 m msl), due to their geographical location and complex topography, are reported to be highly sensitive to climatic ...

Simulation of the 2018 Global Dust Storm on Mars Using the NASA Ames Mars GCM: A Multi-Tracer Approach [PDF]

open access: yes, 2019
Global dust storms are the most thermodynamically significant dust events on Mars. They are produced from the combination of multiple local and regional lifting events and maintained by positive radiative-dynamic feedbacks. The most recent of these events, which began in June 2018, was monitored by several spacecraft in orbit and on the surface, but ...

Rational Design and Organoid‐Based Evaluation of a Cocktail CAR‐γδ T Cell Therapy for Heterogeneous Glioblastoma

open access: yesAdvanced Science, EarlyView.
A novel “prof” cocktail therapy is designed. It screens antigens, selects personalized antigen panels, engineers optimized CAR‐Vδ1 T cells, and tests in patient‐derived GBM organoids, offering hope for effective CAR‐T drugs against heterogeneous solid tumors. Abstract Various challenges, including tumor heterogeneity and inadequate T cell infiltration,

A micro‐geoarchaeological investigation of a cultivation pit (maite) on Teti'aroa atoll, Central‐East Polynesia

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT Cultivation pits represented the principal form of horticultural features developed by past atoll communities in Central‐East Polynesia (CEP), and they are still utilised on some atolls in Oceania. The majority of information about the use of cultivation pits in CEP derives from ethnographic and preliminary archaeological investigations.
