GFP-Margatoxin, a Genetically Encoded Fluorescent Ligand to Probe Affinity of Kv1.3 Channel Blockers
Peptide pore blockers and their fluorescent derivatives are useful molecular probes to study the structure and functions of the voltage-gated potassium Kv1.3 channel, which is considered as a pharmacological target in the treatment of autoimmune and neurological disorders. We present Kv1.3 fluorescent ligand, GFP-MgTx, constructed on the basis of green fluorescent protein (GFP) and margatoxin…
Read MoreThe Discovery and Function of Filaggrin
Keratohyalin granules were discovered in the mid-19th century in cells that terminally differentiate to form the outer, cornified layer of the epidermis. The first indications of the composition of these structures emerged in the 1960s from a histochemical stain for histidine, followed by radioautographic evidence of a high incidence of histidine incorporation into newly synthesized…
Read MoreThe Current State of Chromatin Immunoprecipitation (ChIP) from FFPE Tissues
Cancer cells accumulate epigenomic aberrations that contribute to cancer initiation and progression by altering both the genomic stability and the expression of genes. The awareness of such alterations could improve our understanding of cancer dynamics and the identification of new therapeutic strategies and biomarkers to refine tumor classification and treatment. Formalin fixation and paraffin embedding…

We have developed a low-cost optical cavity-based biosensor with a differential detection method for point-of-care medical diagnostics. To experimentally demonstrate its label-free real-time biosensing capability, we performed the detection of biotinylated bovine serum albumin (BSA). Streptavidin is introduced into the optical cavity structure and immobilized on 3-aminopropyltriethoxysilane (APTES) coated surface. After rinsing out unbound streptavidin…
Read MoreUltrasonographic observation in combination with progesterone monitoring for detection of ovulation in Labrador Retrievers
Although it is well known that the ovulation occurs during a period of time after LH surge in dogs, there are few reports of observing the entire process of development, ovulation, and luteinization of each follicle. This study aimed to detect the ovulation kinetics by ultrasonography in combination with progesterone monitoring, and therefore identify the…
Read MoreGreen synthesis of zinc oxide particles with apple-derived compounds and their application as catalysts in the transesterification of methyl benzoates
ZnO nanoparticles (ZnONPs) were successfully synthesized using bravo-de-esmolfe apple extract in aqueous medium at room temperature. ZnO microparticles, prepared with a pure apple phytochemical, quercetin (ZnOq), or without phytochemicals (ZnO) were studied for comparative purposes. The re-use of apple waste for highly efficient catalyst production, based on green synthetic routes, can be added to the…
Read MoreValidation of the Applied Biosystems 7500 Fast Instrument for the Detection of Salmonellae with SureTect Salmonella Species PCR Kit.
The Thermo Scientific SureTect Salmonella species real-time PCR assay is a rapid alternative method designed for the detection of salmonellae in a wide range of foods, animal feeds, and production-environment samples. The assay has previously been validated according to the AOAC Research Institute Performance Tested Methods(SM) program using Thermo Scientific PikoReal™ PCR cycler and Thermo…
Read MoreUtilization of a direct sandwich ELISA kit for rapid diagnosis of adenovirus hemorrhagic cystitis in a patient with adult T-cell leukemia
We report on a case of adenovirus hemorrhagi cystitis that developed in a 49-year-old woman during intensive chemotherapy for adult T-cell leukemia. Although rapid etiologic diagnosis is essential for the effective management of viral hemorrhagic cystitis, the isolation of adenovirus from urine is often too time-cousuming. We detected the adenovirus antigen in the patient’s urine…
Read MoreCrystal structure and energetic features of the cocrystal of carbamazepine with 3,5-dinitrobenzoic acid.
The synthesis and detailed description of the crystal structure and energetic features of the 1:1 cocrystal of carbamazepine (5H-dibenzo[b,f]azepine-5-carboxamide, CBZ) with 3,5-dinitrobenzoic acid (35DNBA), i.e. C15H12N2O·C7H4N2O6, are reported. The CBZ and 35DNBA molecules are packed in alternately arranged layers. Two characteristic R22(8) and R22(16) hydrogen-bond ring motifs have been found. The supramolecular architecture, besides the…
Read MoreCo-occurrence of odor-causing dioxanes and dioxolanes with bis(2-chloro-1-methylethyl) ether in Huangpu River source water and fates in O 3-BAC process
In recent years, dioxanes and dioxolanes have been intermittently detected in water environment and have caused several offensive drinking water odor incidents worldwide. In this study, the co-occurrence of eight dioxanes, twelve dioxolanes and bis(2-chloro-1-methylethyl) ether was investigated in Huangpu River watershed to explore potential sources and contributions to septic/chemical odor. Totally 8 dioxanes and…
