Contrasting range changes of terrestrial orchids under future climate change in China.

Climate change has impacted the distribution and abundance of numerous plant and animal species during the last century. Orchidaceae is one of the largest yet most threatened families of flowering plants. However, how the geographical distribution of orchids will respond to climate change is largely unknown.

Geographic patterns of taxonomic and phylogenetic β-diversity of aquatic angiosperms in China.

China covers a vast territory harbouring a large number of aquatic plants. Although there are many studies on the β-diversity of total, herbaceous or woody plants in China and elsewhere, few studies have focused on aquatic plants. Here, we analyse a comprehensive data set of 889 aquatic angiosperm species in China, and explore the geographic patterns and climatic correlates of total taxonomic and phylogenetic β-diversity as well as their turnover and nestedness components.

Metagenomic Features Characterized with Microbial Iron Oxidoreduction and Mineral Interaction in Southwest Indian Ridge.

The Southwest Indian Ridge (SWIR) is one of the typical representatives of deep-sea ultraslow-spreading ridges, and has increasingly become a hot spot of studying subsurface geological activities and deep-sea mining management. However, the understanding of microbial activities is still limited on active hydrothermal vent chimneys in SWIR. In this study, samples from an active black smoker and a diffuse vent located in the Longqi hydrothermal region were collected for deep metagenomic sequencing, which yielded approximately 290 GB clean data and 295 mid-to-high-quality metagenome-assembled genomes (MAGs).

Medial patellofemoral ligament reconstruction: A review.

Introduction: Reconstruction of the medial patellofemoral ligament (MPFL) is an effective surgical method for the treatment of lateral patellar instability. At present, there is not much controversies regarding the femoral attachment, however, the controversies regarding patellar attachment versus attachment, number of graft strands, tension, isometry and so on. The following electronic databases will be searched: PubMed, the Cochrane Library, Embase, Web of Science, Medline.

Impact of the Result of Continued Thrombolysis After Stenting Following Pharmacomechanical Thrombectomy for Iliofemoral Deep Vein Thrombosis-A Retrospective Study.

Objective: The aim of this study is to compare the procedure and treatment outcomes of using either direct stenting alone following pharmacomechanical thrombectomy or continued catheter-directed thrombolysis after stenting for treatment of acute left iliofemoral deep vein thrombosis while clot removal degree achieved grade III.

Methods: From March 2018 to May 2019, 82 patients who underwent iliac venous stenting for treatment of acute left iliofemoral deep vein thrombosis with iliac vein stenosis after pharmacomechanical thrombectomy therapy using the AngioJet system while Clot removal degree achieved grade III were divided into two groups: Direct stenting alone group ( = 39) and continued catheter-directed thrombolysis after stenting group ( = 43). Comparisons were made regarding the treatment outcomes, stent patency rate, and Villalta scale between these two groups.

RBP-J promotes cell growth and metastasis through regulating miR-182-5p-mediated Tiam1/Rac1/p38 MAPK axis in colorectal cancer.

Background: RBP-J is involved in number of cellular processes. However, the potential mechanisms of RBP-J on colorectal cancer (CRC) development have not been clearly defined. In this study, we aimed to investigate the role and molecular mechanism of RBP-J in CRC.

Modeling impacts of climate change on the potential distribution of six endemic baobab species in Madagascar.

Madagascar, a globally renowned biodiversity hotspot characterized by high rates of endemism, is one of the few remaining refugia for many plants and animal species. However, global climate change has greatly affected the natural ecosystem and endemic species living in Madagascar, and will likely continue to influence species distribution in the future. Madagascar is home to six endemic baobab ( spp.

LncRNA FTX Promotes Colorectal Cancer Cells Migration and Invasion by miRNA-590-5p/RBPJ Axis.

Colorectal cancer (CRC) is one of the most lethal human cancers all over the world. Moreover, it ranks fourth for cancer-related deaths among males. Although many efforts have been made to cure CRC, the effect remains limited.

Endovascular treatment for long segment iliac artery occlusion involving the iliac artery opening.

Objective: This retrospective nonrandomized study investigated the outcomes of endovascular therapy for long-segment iliac artery occlusion involving the iliac artery opening.

Methods: During a 5-year period (from Mar 2012 to Mar 2017), 32 patients (two women and 30 men; mean age, 69.0 years; range, 51-90 years) received endovascular therapy, with or without catheter-directed thrombolysis (CDT), for long-segment iliac artery occlusion (mean lesion length, 129.

A new species of (Annelida, Eunicida, Dorvilleidae) from hydrothermal vents on the Southwest Indian Ridge.

Dorvilleids were collected from hydrothermal vents on the Southwest Indian Ridge by manned submersible . These represent a new species of that is here described as This is the first dorvilleid described from vents on the Southwest Indian Ridge. It most closely resembles another vent species, Blake, 1985 from the Galapagos Rift, but can be distinguished by its antennae, palps, jaw structure.

Aquaticitalea lipolytica gen. nov., sp. nov., isolated from Antarctic seawater.

A Gram-stain-negative, rod-shaped bacterium, designated Ar-125, was isolated from Antarctic seawater. It produced carotenoid-like pigments and did not produce Bchl a. Ar-125 was positive for hydrolysis of DNA, aesculin, gelatin, starch, Tween 40 and Tween 60.

[Development and application of Jingcen DY-1 spraying tanker for Oncomelania hupensis snail control].

Objective: To develop a Jingcen DY-1 type spraying tanker for Oncomelania hupensis snail control and evaluate its effect of field application as well as the cost.

Methods: The currently available tractor was used as a vector, and the mechanical and electrical equipments and containers were integrated with shafts, pipelines and electric lines to produce a spraying tanker for snail control, with the functions of carrying people and molluscicides, generating electric power and getting water, mixing stocking solutions, adjusting molluscicide solutions evenly, and spraying drugs. The volume of the molluscicide solution, flow rate of water injection, and the flow rate, range and advance speed of the spray gun were tested, and the solution concentrations of molluscicide in the tanker and at the muzzle of the spray gun at different time were detected.

Muricauda antarctica sp. nov., a marine member of the Flavobacteriaceae isolated from Antarctic seawater.

A Gram-stain-negative, rod-shaped bacterium with appendages, designated Ar-22(T), was isolated from a seawater sample collected from the western part of Prydz Bay, near Cape Darnley, Antarctica. Strain Ar-22(T) grew optimally at 35 °C, at pH 7.5 and in the presence of 1-3% (w/v) NaCl.

Identification and characteristics of a novel E1 like gene nUBE1L in human testis.

A gene, presumably involved in spermatogenesis, was identified and characterized by using cDNA microarray. Hybridization intensity was 2.13 fold higher in adult testis than that in fetal testis.

Expression of a novel HsMCAK mRNA splice variant, tsMCAK gene, in human testis.

Identification of specifically expressed genes in the adult or fetal testis is very important for the study of genes related to the development and function of the testis. In this study, a human adult testis cDNA microarray was constructed and hybridized with 33P-labeled human adult and embryo testis cDNA probes, respectively. After differential display analyzing, a number of new genes related to the development of testis and spermatogenesis had been identified.
