We present the first global analysis of fragmentation functions for light charged hadrons (π^{±}, K^{±}) at full next-to-next-to-leading order in quantum chromodynamics, incorporating world data from both single-inclusive electron-positron annihilation and semi-inclusive deep-inelastic scattering. The collinear factorization has been tested with low-momentum-transfer data and has demonstrated success at high hadron momenta. Additionally, we study the impact of current global data on hadron production to the parton distribution functions (PDFs), and find they favor a reduced asymmetry in the strange (anti)quark PDFs, as compared to the asymmetry predicted by state-of-the-art PDFs derived from inclusive data.

We perform a simultaneous global analysis of hadron fragmentation functions (FFs) to various charged hadrons (π^{±}, K^{±}, and p/p[over ¯]) at next-to-leading order in QCD. The world data include results from electron-positron single-inclusive annihilation, semi-inclusive deep inelastic scattering, as well as proton-proton collisions including jet fragmentation measurements for the first time, which lead to strong constraints on the gluon fragmentations. By carefully selecting hadron kinematics to ensure the validity of QCD factorization and the convergence of perturbative calculations, we achieve a satisfying best fit with χ^{2}/d.

The citrus red mite, , a major citrus pest distributed worldwide, has evolved severe resistance to various classes of chemical acaricides/insecticides including pyrethroids. It is well known that the resistance to pyrethroids is mainly caused by point mutations of voltage-gated sodium channel gene in a wide range of pests. However, increasing number of evidences support that pyrethroids resistance might also be resulted from the integrated mechanisms including metabolic mechanisms.

Serum samples were pre-operational collected from 86 patients with gastric cancer from Tianjin Medical University Cancer Institute and Hospital from March 2016 to August 2016. The serum of APE1 was measured by ELISA development kit and other CA242, CA724, CA199 and CEA levels by electrochemiluminescence assay.

However, sustained use of abamectin has led to the development of resistance in some target species. Previous studies on arthropod resistance to abamectin have mainly used traditional biochemical and molecular approaches.

The citrus red mite, Panonychus citri (McGregor), is a major citrus pest with a worldwide distribution and an extensive record of pesticide resistance. However, the underlying molecular mechanism associated with fenpropathrin resistance in this species have not yet been reported. In this study, synergist triphenyl phosphate (TPP) dramatically increased the toxicity of fenpropathrin, suggesting involvement of carboxylesterases (CarEs) in the metabolic detoxification of this insecticide.

Chitinases are hydrolytic enzymes that are required for chitin degradation and reconstruction in arthropods. In this study, we report a cDNA sequence encoding a putative chitinase (PcCht1) from the citrus red mite, Panonychus citri. The PcCht1 (564 aa) possessed a signal peptide, a conserver domain, and a chitin-binding domain.

The interactions of bovine serum albumin (BSA) with five novel silicon (N) phthalocyanines(SiPcl-5) axially modified by nucleosides (cytidine, 5-N-cytidine, methyl cytidine, uridine and methyl uridine) derivatives were studied by fluorescence spectroscopy. The results show that there are strong interactions between these silicon phthalocyanines and BSA with a binding constant of (4.90-83.

Acid-sensing ion channels (ASICs) are H(+), Ca(2+), and Na(+)-gated cation channels that are activated by changes in the extracellular pH, and ASIC1α may be associated with tumor proliferation and migration. Here, we investigated the role of ASIC1α in hepatocellular carcinoma (HCC) migration and invasion.

The uridine-containing compound 1 exhibits the highest photocytotoxicity against HepG2 human hepatocarcinoma cells with an IC50 value as low as 6 nM, which can be attributed to its high cellular uptake and non-aggregated nature in the biological media. This compound shows high affinity toward the mitochondria of HepG2 cells and causes cell death mainly through apoptosis upon illumination.

Objective: To report a rare case of brucellosis with myelo-dysplastic syndrome (MDS).
Clinical Presentation And Intervention: A 70-year-old woman presented with pancytopenia and fever of unknown origin (FUO). The initial diagnosis was brucellosis; the woman was treated with doxycycline and rifampin against Brucella melitensis but was later diagnosed as suffering from MDS.
Background: While fever of unknown origin (FUO) remains a challenging problem in clinical practice, fluorine-18 fluorodeoxyglucose ((18)F-FDG) positron emission tomography/computed tomography (PET/CT) has been considered helpful in diagnosing its cause. The present study is set to evaluate the diagnostic value of PET/CT for patients with FUO.
Methods: We analyzed the records of 48 patients with FUO (34 men and 14 women; mean age of 57-year-old with a range between 24- and 82-year-old).
