An aptamer based method is described for the determination of 8-hydroxy-2'-deoxyguanosine (8-OHdG) using resonance light scattering (RLS). Magnetic nanoparticles (MNPs) were employed as RLS probes. The probe DNA was placed on the surface of MNPs, which produces a rather low RLS signal. If, however, probe DNA hybridizes with the aptamer against 8-OHdG, a sandwich structure will be formed. This results in a significant enhancement of RLS intensity. The aptamer was used as the recognition element to capture 8-OHdG...

Renal interstitial fibrosis (RIF) is difficult to diagnose. This paper explored liquid biopsy markers in urinary exosomes derived from RIF patients. Urine samples from 32 patients with various degrees of RIF and 20 non-RIF patients were collected. The size and morphology of urinary exosomes isolated by polyethylene glycol were observed with electron microscopy. Protein biomakers of exosomes were analyzed by Western blot. qRT-PCR was used to detect the levels of biomarkers (miR-29c, miR-21, E-cadherin, and vimentin) of epithelial mesenchymal transition in urinary exosomes...

The elimination of cephalexin (CPX) using electro-generated Cl2 -active on Ti/RuO2 -IrO2 anode was assessed in different effluents: deionized water (DW), municipal wastewater (MWW) and urine. Single Ti/RuO2 and Ti/IrO2 catalysts were prepared to compare their morphologies and electrochemical behavior against the binary DSA. XRD and profile refinement suggest that Ti/RuO2 -IrO2 forms a solid solution, where RuO2 and IrO2 growths are oriented by the TiO2 substrate through substitution of Ir by Ru atoms within its rutile-type structure...

A controlled kinetic study was conducted in volunteers dermally exposed to the widely used lambda-cyhalothrin pyrethroid pesticide to document the time courses of relevant biomarkers of exposure, in order to better assess biomonitoring data in workers. Matador® EC120 formulation (120 g/l) was applied on 40 cm2 of the forearm at a 0.25 mg/kg dose of lambda-cyhalothrin and left without occlusion or washing for 6 h. The application site was then washed thoroughly with soap and water. The kinetic time courses of cis-3-(2-chloro-3,3,3-trifluoroprop-1-en-1-yl)-2,2-dimethylcyclopropane carboxylic acid (CFMP) and 3-phenoxybenzoic acid (3-PBA) metabolites were determined in plasma and urine up to 84 h post-application...

'Pregnancy of unknown location' is a non-diagnostic transvaginal ultrasound scan in early pregnancy. The scan may be non- diagnostic because the pregnancy is too small to identify, too difficult to identify or gone - already passed during the process of miscarriage. Many patients are surprised to learn that urine pregnancy tests are more sensitive in detecting a pregnancy than ultrasound scans, but as long as this remains the case, or until we discover a biomarker that can locate a pregnancy, the management of women with PUL will continue to form a significant part of the workload of Early Pregnancy Units...

We have recently developed a sensitive and specific urine-based antigen detection ELISA for the diagnosis of visceral leishmaniasis (VL). This assay used rabbit IgG and chicken IgY polyclonal antibodies specific for the Leishmania infantum proteins iron superoxide dismutase 1 (Li-isd1), tryparedoxin1 (Li-txn1), and nuclear transport factor 2 (Li-ntf2). However, polyclonal antibodies have limitations for upscaling and continuous supply. To circumvent these hurdles, we began to develop immortalized monoclonal antibodies...

Enterococcus faecium is an important health care-associated pathogen that is difficult to treat due to the high level of antibiotic resistance of clinical isolates. The identification of new potential therapeutic targets or vaccination strategies is therefore urgently needed. In this regard, we carried out a transcriptomic analysis of the E. faecium vancomycin-resistant strain AUS0004, comparing the gene expression of bacteria grown under laboratory conditions and bacteria isolated from an infection site. This analysis highlighted more than 360 genes potentially induced under infection conditions...

Nowadays, there are rising concerns about the extensive use of the antibiotics such as chloramphenicol (CAP), has threatened the human life in the form of various vicious diseases. The limited selectivity and sensitivity of confirmatory techniques (UV and electrochemical) and non-fluorescence property of CAP make its determination a challenging task in the modern pharmaceutical analysis. In order to redeem the selective, sensitive and cost-effective fluorescence methodology, here by the dual role of synthesized porous SnO2 nanoparticles were exploited; (i) a porous sorbent in a µ-QuEChERS based sample preparation and as (ii) a stimulant for the transformation of non-fluorescent analytes namely CAP and p-nitrophenol (p-NP) into their respective fluorescent product...

BACKGROUND: miR-29 is a master regulator of extracellular matrix genes, but conflicting data on its anti-fibrotic effect have been reported. miR-29 improves nitric oxide (NO) production in arterioles by targeting Lypla1. Mir29b1 targeted mutation exacerbates hypertension in a model derived from the Dahl salt-sensitive rat. We examined the effect of Mir29b1 mutation on tissue fibrosis and NO levels with a focus on kidney regions. METHODS: Mir29b1 targeted mutant rats on the genetic background of SS-Chr13BN rats were studied...
