[LAPAROSCOPIC LIVE DONOR NEPHRECTOMY WITH HORSESHOE KIDNEY: A CASE REPORT].

We performed laparoscopic live donor nephrectomy (LDN) on approximately 200 patients in Ehime Prefectural Center Hospital between 2003 and 2016. In 2016, a fifty-something woman who was a donor candidate for her husband was revealed to have a horseshoe kidney through contrast-enhanced computed tomography; other LDN procedures used a retroperitoneal approach, but this one used a transperitoneal approach since the latter approach allowed for a more favorable visual field. The left kidney was selected since renal scintigraphy showed equal bilateral renal function and renal arteries are simpler on the left side.

A case of an advanced renal collecting duct carcinoma in which initial therapeutic effect was achieved with pembrolizumab plus axitinib.

Introduction: Renal collecting duct carcinoma is often found in advanced cancers and has a poor prognosis. Here, we present the case of symptomatic metastatic collecting duct carcinoma in which we observed an initial therapeutic effect of immune checkpoint inhibitors plus tyrosine kinase inhibitors.

Case Presentation: The patient was a 69-year-old male who was referred to our hospital for examination of a right chest tumor and related pain.

A simple and selective fluorometric assay for dopamine using a calcein blue-Fe2+ complex fluorophore.

A novel fluorimetric assay for dopamine using calcein blue (CB) complexed with Fe(2+) ion as a chemical sensor is described. The fluorescence arising from CB of the CB-Fe(2+) complex is quenched by the Fe(2+) ion. When dopamine is added to a solution of the CB-Fe(2+) complex, a dopamine-Fe(2+) complex is formed as the result of a ligand exchange reaction between CB and dopamine which permits the fluorescence from CB to be recovered.

An amphiphilic fluorescent probe for the visualization of histamine in living cells.

A novel fluorescent probe composed of two moieties, Nile Red and an iminodiacetic acid-Ni(2+) complex, for the detection of histamine in living cells is described. The probe was successfully applied to visualizing histamine in RAW264 cells, representing the first demonstration of the imaging of histamine itself in living cells.

Selective fluorescence detection of histamine based on ligand exchange mechanism and its application to biomonitoring.

We report on a novel histamine monitoring method by using a fluorescent probe, a complex between Ni(2+) and calcein, based on a ligand exchange mechanism. The fluorescence intensity of this probe, which has been reduced due to effective quenching by Ni(2+) ion, increases drastically by an addition of histamine. Furthermore, the probe shows high selectivity toward histamine among the various neurotransmitters in 0.

Sequential injection chemiluminescence immunoassay for anionic surfactants using magnetic microbeads immobilized with an antibody.

A rapid and sensitive immunoassay for the determination of linear alkylbenzene sulfonates (LAS) is described. The method involves a sequential injection analysis (SIA) system equipped with a chemiluminescence detector and a neodymium magnet. Magnetic beads, to which an anti-LAS monoclonal antibody was immobilized, were used as a solid support in an immunoassay.

Phospholipid-linked coumarin: a fluorescent probe for sensing hydroxyl radicals in lipid membranes.

A fluorescent probe, DPPEC (1,2-dipalmitoylglycerophosphorylethanolamine labeled with coumarin) was developed for detecting hydroxyl radical (*OH) in lipid membranes. The coumarin moiety contributes to the fluorescent detection of *OH and the phospholipids moiety gives a driving force to localize the probe in lipid membranes. DPPEC in liposomal membranes rapidly reacted with *OH and increased the fluorescence intensity, depending on the concentration of *OH.

Methodology of reversible protein labeling for ratiometric fluorescent measurement.

The first fluorescent labeling technology, which can induce not only an increase in the fluorescence intensity but also a shift in the fluorescence spectrum, has been developed for "ratiometric" measurements for a protein by utilizing a newly designed "field-sensitive" fluorescent probe and its corresponding unique amino acid tag.
