Background and Objective: Denosumab is a valuable and safe therapy for skeletal disorders in adults and has received regulatory approval to treat osteoporosis and bone metastases. However, denosumab is not licensed for pediatric use due to a lack of high-quality prospective research on children. This study aimed to describe and discuss the benefits and disadvantages of denosumab in treating bone diseases in children and to summarize the current understanding of the role of denosumab therapy in children.Methods: A narrative review was conducted using the literature retrieved from the PubMed, Embase, and Cochrane Library databases.
Sodium-ion
batteries (SIBs) have attracted significant attention
as promising next-generation energy storage devices. However, the
research and development of SIBs are still in their infancy due to
the lack of suitable high-performance anode materials. As a commercial
anode material for lithium-ion batteries (LIBs), graphite often shows
a low sodium storage capacity. Herein, a graphite heterojunction material
was prepared through a facile ball-milling method. During the ball-milling
process, a defect-enriched g-C3N4/graphite heterojunction
was formed and the nitrogen-containing functional groups were regulated,
which promoted the sodium storage capacity. The resulting g-C3N4/graphite electrode can exhibit excellent long
cycle stability and rate performance, delivering a high reversible
capacity of 202 mAh g–1 at 1.0 A g–1 after 6000 cycles and 90.06 mAh g–1 at 5.0 A g–1 after 10000 cycles. Moreover, an ultrahigh rate capability
can also be obtained at 1.0 A g–1 with a capacity
of 111 mAh g–1. The superiority of heterostructures
for sodium storage and diffusion was proved via DFT calculations,
which verified the synergistic effect between graphite and g-C3N4. This study provides a simple and efficient
method for preparing g-C3N4/graphite heterostructures
as well as a deep insight into the sodium storage mechanism of a heterostructure
anode.
Unified water flow regulation has been implemented in the Yellow River, Hei River and Tarim River in China since 1999 as a result of institutional reforms. It has been one of the most important water resources management practices in China during recent years and has generated significant impacts. Based on the data of such an experiment in the Yellow River during 1999 to 2004, a "with-without" scenario analysis method is employed in the paper to evaluate the economic and hydrological impacts of regulation through a holistic model coupling economic water use and hydrologic cycle applied to the study basin. The results show that about 2.5% of GDP was increased every year and the Flow Cutoff Events were avoided as a result of the unified water flow regulation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
