Molecular Design of Polymeric Metal-Organic Nanocapsule Networks for Solid-State Lithium Batteries.

Solid-state electrolytes (SSEs) have emerged as high-priority materials for ensuring the safe operation of solid-state lithium (Li) batteries. However, current SSEs still face challenges of balancing stability and ionic conductivity, which limits their practical applications in solid-state Li batteries. Here, we report a general strategy for achieving high-performance SSEs by constructing a Li-conducted polymeric metal-organic nanocapsule (PolyMONC(Li)) network through molecular design.

Amlexanox (ALX) is a small-molecule drug for the treatment of inflammatory, autoimmune, metabolic, and tumor diseases.

Energy consumption, environmental pollution, and technological innovation efficiency: taking industrial enterprises in China as empirical analysis object.

Facing increasingly serious environmental problems, technological innovation has become the key for industrial enterprises to coordinate energy conservation and emission reduction constraints and achieve steady growth of the industrial economy. Considering the impact of energy consumption and environmental pollution on the technological innovation efficiency of industrial enterprises, this paper incorporates industrial energy consumption, pollution control, and wastewater and exhaust emissions into the technical inefficiency equation. Based on the panel data of industrial enterprises in 30 provinces and autonomous regions in China from 2009 to 2016, the stochastic frontier analysis (SFA) model is used to study the effect of energy consumption and environmental pollution on technological innovation efficiency of industrial enterprises.

Dickkopf-1 enhances migration of HEK293 cell by beta-catenin/E-cadherin degradation.

Migration is an important process during cellular activity and embryo development.

Developmental and hormonal regulation of meltrin beta (ADAM19) expression in mouse testes during embryonic and postnatal life.

More than half of ADAM (a disintegrin and metalloprotease) family members are expressed in mammalian male reproductive organs such as testis and epididymis. The ADAM19 gene identified in mouse is a member of the ADAM family and is highly enriched in testes of a newborn mouse. The present study was performed to determine its expression pattern in whole mouse testes in vivo as well as its in vitro action and regulation in testis cells from 2-day-old mice.

Role of sonic hedgehog in maintaining a pool of proliferating stem cells in the human fetal epidermis.

Background: The mammalian epidermis is maintained by the ongoing proliferation of a subpopulation of keratinocytes known as epidermal stem cells. Sonic hedgehog (Shh) can regulate morphogenesis of hair follicles and several types of skin cancer, but the effect of Shh on proliferation of human putative epidermal stem cells (HPESCs) is poorly understood.

Methods And Results: We first found that Shh, its receptors Patched1 (Ptc1) as well as Smoothened (Smo) and its downstream transcription factor Gli-1 were expressed in the basal layer of human fetal epidermis and freshly sorted HPESCs.
