The kidney is a complex organ with more than 20 types of specialized cells that play an important role in maintaining the body's homeostasis. The epithelial tubular cell is formed during embryonic development and has little proliferative capacity under physiological conditions, but after acute injury the kidney does have regenerative capacity. However, after repetitive or severe lesions, it may undergo a maladaptation process that predisposes it to chronic kidney injury. Regenerative medicine includes various repair and regeneration techniques, and these have gained increasing attention in the scientific literature...

Increasing evidence indicates that reduced intracellular drug accumulation is the parameter most consistently associated with platinum drug resistance, and emphasizes the need to directly measure intra-tumor drug concentration. In the era of precision medicine and with the advent of powerful imaging and proteomics technologies, there is an opportunity to better understand drug resistance, by exploiting these techniques to provide new knowledge on drug-target interactions. Here, we are contributing to this endeavor by reporting on the development of a fluorine-18 labeled carboplatin derivative ((18)F-FCP) that can be used to potentially image drug uptake and retention, including intra-tumoral distribution, by positron emission tomography (PET)...

Makiko Shimizu, Hiroshi Yamazaki
Trimethylamine, a dietary- and medicinal carnitine-derived amine, is extensively metabolized by liver to non-malodorous trimethylamine N-oxide. Although trimethylamine and trimethylamine N-oxide under daily dietary consumption or carnitine treatment are generally regarded as nontoxic, they have been, and remain, of toxicological and clinical interest because of their potential association with atherosclerosis. The aim of the current study was to model the pharmacokinetics of trimethylamine after oral administration of trimethylamine in humans and compare the results with reported measured values...

BACKGROUND: Despite the advances in cardiovascular medicine, acute coronary syndrome (ACS) is still a major cause of morbidity and mortality worldwide. Synergy between PCI ™ with TAXUS and Cardiac Surgery (SYNTAX) score is used to determine the extensivity and complexity of coronary artery disease (CAD). Renal resistive index (RRI), a renal Doppler ultrasound parameter, is used to detect renal hemodynamics. Although some risk factors for CAD, including hypertension and diabetes mellitus were demonstrated to have an association with RRI, direct relationship between the presence...

Application of ultrasound contrast media has become a standard in diagnostic imaging in cardiology and in the characterization of focal lesions in multiple organs, especially of the liver. In the past years there was a growing body of evidence for their usefulness in vascular medicine. The development of contrast media, microbubbles with a stabilizing envelope and filled with gaz, small enough to pass through pulmonary capillaries made real-time imaging of organ perfusion possible. Ultrasound contrast media are rapidly eliminated by exhalation and can safely be administered to patients with renal failure...

Lorenzo Signorini, Simona Granata, Antonio Lupo, Gianluigi Zaza
Oxidative stress is a well-described imbalance between the production of reactive oxygen species (ROS) and the antioxidant defense system of cells and tissues. The overproduction of free radicals damages all components of the cell (proteins, lipids, nucleic acids) and modifies their physiological functions. As widely described, this condition is a biochemical hallmark of chronic kidney disease (CKD) and may dramatically influence the progression of renal impairment and the onset/development of major systemic comorbidities including cardiovascular diseases...

A 64-year-old man was diagnosed with chronic-phase chronic myelogenous leukemia(CML)in May 2009. He was treated with imatinib and achieved complete cytogenetic response(CCyR)in 2 months. After 4 months of treatment, he developed interstitial pneumonia and became intolerant to imatinib. He was then switched to nilotinib from October of the same year. In June 2013, he was diagnosed with drug-induced pericarditis resulting from nilotinib use, and thus, nilotinib was discontinued. Subsequently, he was followed up without specific treatment for CML...

REVIEW
C Stelzner, N Abolmaali, U Hecker, S Schellong
Visceral vessel processes are primarily or secondarily included in a multitude of clinical abdominal symptoms, with which the specialist in internal medicine is confronted. The spectrum ranges from more sharply outlined manifestations, such as chronic ischemic bowel disease up to dysfunctional disturbances of blood pressure regulation, such as high-grade renal artery stenosis. Sometimes diseases with prognostic implications, such as arterial aneurysms, are revealed as incidental findings. As a rule the B‑mode and duplex ultrasound can often be complemented by computed tomography (CT) and magnetic resonance imaging (MRI), as in aneurysms or portal vein thrombosis or the indications for subsequent digital subtraction angiography (DSA) and catheter-based therapy can be directly obtained from duplex and Doppler ultrasound...

The present study aimed to determine the effect of Astragalus polysaccharide (APS) in an in vivo and in vitro rat model of muscle atrophy (cachexia) caused by chronic renal failure (CRF), along with the potential corresponding roles of atroglin-1 and the ubiquitin-proteasome pathway. A rat model of CRF was established using subtotal bilateral nephrectomy. It was observed by reverse transcription-quantitative polymerase chain reaction and western blot analysis that APS and the specific inhibitor of nuclear factor (NF)-κB, pyrrolidine dithiocarbamate (PDTC), significantly reduced the expression of atrogin-1, ubiquitin and the NF-κB subunit p65 mRNA in rat skeletal muscle in vivo and in vitro, respectively (P<0...

REVIEW
João S Orvalho, Larry D Cowgill
Cardiorenal syndrome (CRS) has not been well characterized in veterinary medicine, yet an accurate appreciation of the kidney and the cardiovascular system and their interactions may have practical clinical implications. A consensus for cardiovascular-renal axis disorders of dogs and cats was recently attempted. The outcome of patients with CRS is likely to improve with the increasing awareness and ability to identify and understand the pathophysiologic characteristics of CRS. The utilization of existing and emerging organ-specific biomarkers with greater sensitivities than conventional diagnostics forecast new opportunities to diagnose and manage cardiac disease...
