Radial growth responses of three coniferous species to climate change on the southern slope of Funiu Mountains, China.

Funiu Mountains are located in a transition region between warm temperate zone and northern subtropical region, where a variety of plant species are distributed with sensitive response to climate change. Their response characteristics to climate change are still unclear. We developed the basal area increment (BAI) index chronologies of , , and in the Funiu Mountains to examine their growth trend and their sensitivity to climatic change.

Etching process enhanced HO sensing performance of SnO/ZnSnO with reliable anti-humidity ability.

In this work, sol-gel and chemical etching methods are adopted to synthesize zinc hydroxystannate materials. Cubic tin dioxide and zinc stannate composite materials with a definite structure are successfully prepared at varied annealing temperatures and times by using the synthesized zinc hydroxystannate as a sacrificial template. After a gas sensing test, tin dioxide and zinc stannate composite samples etched at 650 °C and annealed for 4 h exhibit a strong response and outstanding selectivity to hydrogen peroxide.

A Novel Homozygous Frameshift Mutation in ITGB3 Causes Glanzmann's Thrombasthenia.

LncRNA SNHG5 upregulation induced by YY1 contributes to angiogenesis via miR-26b/CTGF/VEGFA axis in acute myelogenous leukemia.

Acute myelogenous leukemia (AML) is the most common acute leukemia in adults. Despite great progress has been made in this field, the pathogenesis of AML is still not fully understood. We report here the biological role of lncRNA small nucleolar RNA host gene 5 (SNHG5) in the pathogenesis of AML and the underlying mechanisms.

High flux hemodialysis in elderly patients with chronic kidney failure.

Background: Hemodialysis is an advanced blood purification technique to manage kidney failure. However, for conventional hemodialysis, the high prevalence of dyslipidemia may cause cardiovascular diseases and an increase in mortality. Moreover, toxins accumulating in the body over time may induce some complications.

Spatial distribution patterns of rock fragments and their underlying mechanism of migration on steep hillslopes in a karst region of Yunnan Province, China.

In mountainous areas, rock fragments (RFs) are a common feature on the soil surface and in topsoil. Few studies, however, have investigated the spatial distribution of RFs and the relevant mechanisms underpinning their distribution on steep hillslopes, especially in karst regions. We have collected and measured the RF cover, size, and content at the soil surface and within the topsoil of secondary forest, man-made forest, and non-forest land hillslopes in a karst region in Yunnan Province, southwest China.

Up-regulation of HCRP1 inhibits proliferation and invasion in glioma cells via suppressing the ERK and AKT signaling pathways.

Hepatocellular carcinoma-related protein 1 (HCRP1), also known as the homologue of vacuolar protein sorting 37A (hVps37A), serves as a membrane trafficking complex to mediate internalization and degradation of ubiquitinated membrane receptors. Recently, more and more researchers have showed that HCRP1 plays a critical role in tumorigenesis. However, the biological roles of HCRP1 in glioma remain to be elucidated.

Photoluminescence properties and thermal stability of blue-emitting BaCl(PO):xEu (0.004≤x≤0.016) phosphors.

A series of blue-emitting BaCl(PO):xEu (0.004≤x≤0.016) phosphors were synthesized by conventional high-temperature solid state reaction.

Direct contact with bone marrow stromal cells promotes the invasions of SHI-1 leukemia cells.

Background: Interactions of tumor cells with the microenvironment were deemed to promote the tumor invasion and metastasis. CXC chemokine receptor 4 (CXCR4) and extracellular matrix metalloproteinase inducer (EMMPRIN) had reported to participate in this process. However the roles of bone marrow microenvironment in leukemic infiltration were not well investigated.

Background: Acinetobacter baumannii, a significant nosocomial pathogen, has evolved resistance to almost all conventional antimicrobial drugs. Bacteriophage therapy is a potential alternative treatment for multidrug-resistant bacterial infections. In this study, one lytic bacteriophage, ZZ1, which infects A.

Effect of interactions between Mip and PrtA on the full extracellular protease activity of Xanthomonas campestris pathovar campestris.

Mip (macrophage infectivity potentiator) and Mip-like proteins have been demonstrated to be involved in virulence of several animal pathogens, but as yet none of their native bacterial targets has been identified. Our previous work demonstrated that the Mip-like protein found in the plant pathogen Xanthomonas campestris pv. campestris (Xcc) (hereafter called Mip(Xcc)) is also involved in virulence.
