I-labeled m-iodobenzylguanidine ([
I]MIBG) has been used to treat neuroblastoma patients, but [
I]MIBG may be immediately excreted from the cancer cells by the adenosine triphosphate binding cassette transporters, similar to anticancer drugs. The purpose of this study was to clarify the efflux mechanism of [
I]MIBG in neuroblastomas and improve accumulation by inhibition of the transporter in neuroblastomas.

[
I]MIBG was incubated in human embryonic kidney (HEK)293 cells expressing human organic anion transporting polypeptide (OATP)1B1, OATP1B3, OATP2B1, organic anion transporter (OAT)1 and OAT2, organic cation transporter (OCT)1 and OCT2, and sodium taurocholate cotransporting polypeptide, and in vesicles expressing P-glycoprotein (MDR1), multidrug resistance associated protein (MRP)1-4, or breast cancer resistance protein with and without MK-571 and probenecid (MRP inhibitors). Time activity curves of [
I]MIBG with and without MK-571 and probenecid were established using an SK-N-SH neuroblastoma cee ratios of [
I]MIBG are improved by inhibition of MRPs with probenecid in neuroblastoma. ADVANCES IN KNOWLEDGE [
I]MIBG, widely used for treatment of neuroendocrine tumors including neuroblastoma, is excreted via MRP1 and MRP4 in neuroblastoma.

Loading with probenecid, OAT, and MRP inhibitors improves [
I]MIBG accumulation.
Loading with probenecid, OAT, and MRP inhibitors improves [131I]MIBG accumulation.Enterocytozoon bieneusi is the most common species responsible for human and animals microsporidiasis. A total of 250 samples were collected weekly from 25 newborn dairy calves of a farm in Southern Xinjiang, China at one to ten weeks of age. Enterocytozoon bieneusi was identified and genotyped by nested PCR amplification and sequencing of internal transcribed spacer (ITS) region.The cumulative prevalence of E. bieneusi infection was 100% (25/25), and the average infection was 52.0% (130/250). click here The highest infection rate was recorded at six weeks of age (92.0%, 23/25), and no infection was observed at one and two weeks of age. Sequencing analysis showed nine E. bieneusi genotypes (J, EbpC, PigEBITS5, CHV4, CHC3, CS-9, KIN-1, CH5, and CAM5) were identified. The highest genetic polymorphism was observed at ten weeks of age. Genotype J was the predominant E. bieneusi genotype. Phylogenetic analysis clustered genotype J into Group 2 and other eight genotypes (EbpC, PigEBITS5, CHV4, CHC3, CS-9, KIN-1, CH5, and CAM5), detected in 22 (16.9%, 22/130) samples, into Group 1. Among the genotypes, EbpC, KIN-1, and J have been identified in humans. The highest E. bieneusi infection rate (57.9%, 124/214) was observed in fecal samples with formed feces with no diarrhea (p less then 0.01), and high genetic polymorphism was observed in class I fecal samples. The presence of zoonotic E. bieneusi genotypes in dairy calves suggests the possibility of transmitting zoonotic infections to humans. It provides the basic data on dynamic change of E. bieneusi in calves.Leptospirosis is a disease with major economic impact on livestock industry. The objective of this work was to determine the presence of Leptospira spp. DNA by qPCR in bovine fetuses with presumptive diagnosis of leptospirosis as the cause of abortion. Leptospira spp. DNA was detected by qPCR in 11 out of 34 fetuses. These specimens (10/11) had histopathological findings in hepatic and/or renal tissues compatible with leptospirosis. qPCR detection rate (32.4 %) was higher compared with direct immuno-fluorescence antibody test (DFAT) (11.8 %). click here The concordance coefficient between both techniques was 0.44. qPCR is a rapid and sensitive technique for the diagnosis of leptospirosis and improved the detection rate in fetal tissues compared with DFAT. Implementation of molecular techniques may increase the accurate detection of leptospirosis as a cause of bovine abortion allowing the application of rapid therapeutic and prophylactics measures in order to reduce the impact of this zoonotic disease.The global increase in multidrug-resistant pathogens has caused severe problems in the treatment of infections. To overcome these difficulties, the advent of a new chemical class of antibacterial drug is eagerly desired. We aimed at creating novel antibacterial agents against bacterial type II topoisomerases, which are well-validated targets. TP0480066 (compound 32) has been identified by using structure-based optimization originated from lead compound 1, which was obtained as a result of our previous lead identification studies. The MIC90 values of TP0480066 against methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococci (VRE), and genotype penicillin-resistant Streptococcus pneumoniae (gPRSP) were 0.25, 0.015, and 0.06 μg/mL, respectively. Hence, TP0480066 can be regarded as a promising antibacterial drug candidate of this chemical class.Aiming to develop novel ATX inhibitors, an indole-3-carboxylic acid lead Indole-1 was identified through high-throughput screening (HTS) efforts. The Indole-1 analogs 1-7 was firstly prepared which exerted mild activity comparable to Indole-1 (740 nM) in ATX enzyme assay. Further structural modification to identify type IV ATX inhibitors was proceeded through derivatization of the indole-3-carboxylic acid group. Resultantly, compounds 8-17 containing acyl hydrazone linker displayed poor activity (over 3.49 μM). Alternatively, replacing the acylhydrazone linker with urea counterpart by the amide bond reversal principle, the acquired compounds 18-22 achieved obvious improvements with submicromolar activities. Furthermore, with the aim to reducing cLogP, the thiazole ring of 18-22 was altered to the benzamide (23-32) with the urea linker unchanged. Remarkably, the benzamide derivative 24 with 4-hydroxy piperidine fragment was identified which exhibited prominent activity with IC50 value of 2.3 nM. Especially, dedicated molecular docking study was throughout the modification process which qualified 24 as optimal entity in accordance with the ATX inhibitory results.Due to their broad-spectrum antibacterial activity and low cost, tetracyclines (TCs) are a class of antibiotics widely used for human and veterinary medical purposes and as a growth-promoting agent for aquaculture. Interrelationships between TCs and nitrogen cycling have attracted scientific attention due to the complicated processes mediated by microorganisms. TCs negatively impact the nitrogen cycling; however, simultaneous degradation of TCs during nitrogen cycling mediated by microorganisms can be achieved. This review encapsulates the background and distribution of TCs in the environment. Additionally, the main nitrogen cycling process mediated by microorganisms were retrospectively examined. Furthermore, effects of TCs on the nitrogen cycling processes, namely nitrification, denitrification, and anammox, have been summarized. Finally, the pathway and microbial mechanism of degradation of TCs accompanied by nitrogen cycling processes were reviewed, along with the scope for prospective studies.
