Phylogenomics and biogeographical diversification of Collabieae (Orchidaceae) and its implication in the reconstruction of the dynamic history of Asian evergreen broadleaved forests.

The tribe Collabieae (Epidendroideae, Orchidaceae) comprises approximately 500 species. Generic delimitation within Collabieae are confusing and phylogenetic interrelationships within the Collabieae have not been well resolved. Plastid genomes and nuclear internal transcribed spacer (ITS) sequences were used to estimate the phylogenetic relationships, ancestral ranges, and diversification rates of Collabieae.

Exploration of pathogenic microorganism within the small intestine of necrotizing enterocolitis.

Background: Necrotizing enterocolitis (NEC) is the most common severe gastrointestinal emergency in neonates. We designed this study to identify the pathogenic microorganisms of NEC in the microbiota of the small intestine of neonates.

Methods: Using the 16S ribosomal DNA (rDNA) sequencing method, we compared and analyzed the structure and diversity of microbiotas in the intestinal feces of different groups of neonates: patients undergoing jejunostomy to treat NEC (NP group), neonates undergoing jejunostomy to treat other conditions (NN group), and neonates with NEC undergoing conservative treatment (NC group).

Upregulation of FAM50A promotes cancer development.

FAM50A encodes a nuclear protein involved in mRNA processing; however, its role in cancer development remains unclear. Herein, we conducted an integrative pan-cancer analysis using The Cancer Genome Atlas, Genotype-Tissue Expression, and the Clinical Proteomic Tumor Analysis Consortium databases. Based on the gene expression data from TCGA and GTEx databases, we compared FAM50A mRNA levels in 33 types of human cancer tissues to those in corresponding normal tissues and found that FAM50A mRNA level was upregulated in 20 of the 33 types of common cancer tissues.

Correlation of elevated serum uric acid with coronary artery disease in Xinjiang, China: A retrospective case-control study.

Elevated serum uric acid (SUA) levels are associated with coronary artery disease (CAD). However, whether this association is independent of traditional cardiovascular risk factors remains controversial. Our study aimed to determine the concentration of SUA in the presence and severity of CAD in multi-ethnic patients in Xinjiang, China.

7,8-Dihydroxyflavone alleviates cardiac fibrosis by restoring circadian signals via downregulating Bmal1/Akt pathway.

Brain-derived neurotrophic factor (BDNF)/tyrosine kinase receptor B (TrkB) pathway is a therapeutic target in cardiac diseases. A BDNF mimetic, 7,8-dihydroxyflavone (7,8-DHF), is emerging as a protective agent in cardiomyocytes; however, its potential role in cardiac fibroblasts (CFs) and fibrosis remains unknown. Thus, we aimed to explore the effects of 7,8-DHF on cardiac fibrosis and the possible mechanisms.

Realizing Formation and Decomposition of LiO on Its Own Surface with a Highly Dispersed Catalyst for High Round-Trip Efficiency Li-O Batteries.

The rapid and effective formation and decomposition of LiO during cycling is crucial to solve the problems associated with the practical limitation of lithium-oxygen (Li-O) batteries. In this work, a highly dispersed electrocatalyst with Ru nanoclusters inside the special organic molecular cage (RuNCs@RCC3) through a reverse double-solvent method for Li-O batteries has been proposed for the first time. This RuNCs@RCC3 shows an effective catalyst enabling reversible formation and decomposition of the LiO at the interface between the LiO and the liquid electrolyte, rather than the sluggish solid-solid interface reactions on commonly used solid catalysts.

Genotyping of Klebsiella Pneumonia Strains Isolated from Eldly Inpatients by Multiple-locus Variable-number Tandem-repeat Analysis.

Objective To investigate the genotype of klebsiella pneumonia strains isolated from eldly inpatients by multiple-locus variable-number tandem-repeat analysis. Methods Totally 184 klebsiella pneumonia strains,isolated from eldly inpatients,were collected,and their genome DNA were extracted. The polymorphism of 7 variable-number tandem-repeat locus in the DNA samples was analyzed by multiple primers polymerase chain reaction and capillary electrophoresis.

Association between thrombelastography system and thromboembolic and bleeding events in Chinese aged people.

Objectives: This study was designed to obtain the knowledge about TEG indexes distribution in Chinese aged people, as well as to test the hypothesis that previous TEG indexes are associated with the subsequent thromboembolic and bleeding events in the aged population.

Methods: We conducted a two-year follow-up study in Chinese PLA General Hospital, Beijing, China. 403 aged people were enrolled in our study.

[Dynamic investigation on the co-infection status of two pathogens in ticks from tourist point in Heilongjiang province].

Objective: To monitor the co-infection status of Borrelia burgdorferi sensu lato (B.b.s.

Use of covered Cheatham-Platinum stent as the primary modality in the treatment for native coarctation of the aorta.

Background: Bare stent implantation in the treatment for native and recurrent coarctation of the aorta (CoA) has become established as an alternative to surgery and balloon angioplasty. However, this modality still encounters significant complications during the procedure and/or follow-up. The covered Cheatham-Platinum (CP) stent commonly used to be chosen as a rescue treatment in these patients.

[Effects of transcatheter closure of extracardiac Fontan fenestration by Amplatzer duct or septal occluder in three patients].

Objective: The purpose of this study was to report our experiences from the transcatheter closure of patent fenestration after total cavopulmonary connection (TCPC) with an extra cardiac conduit.

Methods: Three patients (7, 14 and 8 years old) with various forms of functionally univentricular heart lesions received a total cavopulmonary connection with an extra cardiac conduit as a final reconstructive procedure. Transcatheter occlusion of the fenestration was accomplished using a 8/6 mm Amplatzer duct occluder in one patient, and 5 mm or 10 mm Amplatzer septal occluder in the other two patients.

Assembly of helical hydrogen bonds in a new layered aluminophosphate [C6N3H17][Al2(HPO4)(PO4)2].

A new layered aluminophosphate, [C6N3H17][Al2(HPO4)(PO4)2] (denoted AlPO-CJ21), has been prepared in an alcoholic system by the use of N-(2-aminoethyl)-piperazine (AEPP) as the template. Its inorganic layer containing a series of bridged six-membered rings (MRs) is a new type of 4.6-net sheet built up from AlO4, PO2(OH)(=O), and PO3(=O) tetrahedra.

Effect of 15-HETE on potassium channels of rabbit pulmonary arterial smooth muscles during hypoxia.

This study investigated the role of 15-hydroxyeicosatetraenoic acid (15-HETE) in rabbit pulmonary arterial smooth muscle cells (PASMCs) under hypoxia by using organ bath and whole cell patch-clamp techniques. Neonatal rabbits born into normoxic environment were transferred after first feeding into normal and hypoxic environments with respectively 0.21 and 0.
