The present study aims to focus on the bioprospecting of marine macroalgae of Turbinaria species, plenteous biomass of the world ocean. Three types of solvents, i.e. water, methanol:water (80:20, v/v) and hexane:isopropanol (50:50, v/v), were used for extraction. Both the biological activity, as well as the pattern of present chemicals were characterized. For the cell proliferation assay, the human embryonic kidney 293 cells, cervix / breast / pancreatic adenocarcinoma, and osteosarcoma cells were used. For the antioxidant activity determination, both intracellular assay with human embryonic kidney and cervix adenocarcinoma cells, as well as the biochemical DPPH test, were employed...

In addition to macronutrients, foods consist of a complex set of chemical compounds that can influence dietary selectivity and consumer physiology. Metabolomics allow us to describe this complexity by quantifying all small molecules, or metabolites, in a food item. In this study we use GC-MS based metabolomics to describe the metabolite profiles of foods consumed by one population of Mexican black howler monkeys (Alouatta pigra) over a 10-month period. Our data indicate that each food exhibited a distinct metabolite profile, and the average weekly intake of metabolites such as neochlorogenic acid and serotonin (5-hydroxytryptamine) was correlated with the consumption of certain plant parts...

The extracellular signal-regulated kinase (ERK) is one of the principal hub proteins that transmit growth signals from upstream oncogene products including Ras and BRaf to downstream effector proteins. However, there are both reports supporting and refuting the increase in ERK activity in cancer tissues expressing the active Ras and BRaf proteins. We considered that the cell density might account for this discrepancy. To examine this possibility, we prepared Madin-Darby canine kidney (MDCK) cells that expressed an active HRas, NRas, KRas, or BRaf and an ERK biosensor based on the principle of Förster resonance energy transfer (FRET)...

Acute kidney injury (AKI) is common after gastric surgery for gastric cancer and associated with adverse outcomes. However, the impact of transient or persistent AKI on clinical outcomes after gastric surgery for gastric cancer has not been described. We performed a retrospective study of 4,886 patients with normal renal function who underwent partial or total gastrectomy for gastric cancer between June 2002 and December 2012. AKI patients were classified as transient and persistent AKI based on the return of serum creatinine to the level indicating no AKI within 7 days...

Epithelial-mesenchymal transition (EMT) of renal tubular epithelial cells is one of the causative mechanisms of kidney fibrosis. In our study, we screened lipophilic compounds using a lipid library including approximately 200 lipids to identify those that suppressed EMT induced by a transforming growth factor (TGF)-β1 stimulus. Initial screening was performed with the immortalized HK-2 renal tubule epithelial cell line. The most promising compounds were further tested in RPTEC primary renal tubule epithelial cells...

The rat has classically been the species of choice for pharmacological studies and disease modeling, providing a source of high-quality physiological data on cardiovascular and renal pathophysiology over many decades. Recent developments in genome engineering now allow us to capitalize on the wealth of knowledge acquired over the last century. Here, we review rat models of hypertension, diabetic nephropathy, and acute and chronic kidney disease. These models have made important contributions to our understanding of renal diseases and have revealed key genes, such as Ace and P2rx7, involved in renal pathogenic processes...

OBJECTIVES: Epithelial cell layers as well as endothelia forming the blood-brain barrier can drastically reduce the efficiency of drug targeting. Our goal was to investigate lectins recognizing the glycosphingolipid globotriaosylceramide (Gb3) for their potential as carriers for transcytotic drug delivery. METHODS: We utilized an in vitro model based on Madin-Darby canine kidney cells transfected with Gb3 synthase to characterize transcytosis of the Gb3-binding lectins LecA from Pseudomonas aeruginosa and the B-subunit of Shiga toxin (StxB)...

Treating infections in pregnant patients is potentially dangerous even when herbal medicines are used. Many herbal medicines, among them extracts from plants of Rhodiola genus, have antimicrobial, anti-inflammatory, and immunostimulatory properties owing to their polyphenol content; they may, however, affect fetal development due to their antiangiogenic properties. The aim of this study was to explain whether daily feeding pregnant and lactating mice with 20 mg/kg Rhodiola kirilowii aqueous (RKW) or 50% hydro-alcoholic (RKW-A) extracts, or 0...

Atherosclerosis, a leading cause of heart disease, results from chronic vascular inflammation that is driven by diverse immune cell populations. Nanomaterials may function as powerful platforms for diagnostic imaging and controlled delivery of therapeutics to inflammatory cells in atherosclerosis, but efficacy is limited by nonspecific uptake by cells of the mononuclear phagocytes system (MPS). MPS cells located in the liver, spleen, blood, lymph nodes, and kidney remove from circulation the vast majority of intravenously administered nanomaterials regardless of surface functionalization or conjugation of targeting ligands...

BACKGROUND: Evidence has suggested that protein from dairy may be less detrimental to renal health than protein from nondairy products. However, to our knowledge, no previous studies have used cystatin C-based measures of the estimated glomerular filtration rate (eGFR). OBJECTIVE: We investigated the associations of sources of protein and dairy with the change in the eGFR in persons with a normal or mildly decreased eGFR. DESIGN: We included 3798 participants, aged 26-65 y, from the Doetinchem Cohort study who were examined ≥3 times 5 y apart...

BACKGROUND: Renal transplant recipients (RTRs) have commonly been urged to limit their potassium intake during renal insufficiency and may adhere to this principle after transplantation. Importantly, in experimental animal models, low dietary potassium intake induces kidney injury through stimulation of ammoniagenesis. In humans, low potassium intake is an established risk factor for high blood pressure. OBJECTIVE: We hypothesized that low 24-h urinary potassium excretion [UKV; urinary potassium concentration × volume], the gold standard for assessment of dietary potassium intake, represents a risk factor for graft failure and mortality in RTRs...

BACKGROUND: Adequate water intake is critical to physiologic and cognitive functioning. Although water requirements increase with body size, it remains unclear whether weight status modifies the relation between water intake and hydration status. OBJECTIVE: We examined how the association between water intake and urine osmolality, which is a hydration biomarker, varied by weight status. DESIGN: NHANES cross-sectional data (2009-2012) were analyzed in 9601 nonpregnant adults aged ≥20 y who did not have kidney failure...

Ann Goodey, Sharon Colman
An ileostomy is where the small bowel is diverted to the abdominal surface resulting in the formation of a stoma. An Ileostomy can be temporary or permanent and produces loose faeces. Some ileostomates can develop high output in the early postoperative stage. Most will resolve, some will require ongoing treatment and management. While patients are monitored closely according to protocol in hospital once discharged into the community, there appears to be little standardisation. A literature search revealed that existing guidelines are for management of patients in the acute care setting...

Li-Wei Yap, Jesper Brok, Kathy Pritchard-Jones
The cell-surface glycoprotein CD56 has three major isoforms that play important roles in cell adhesion and signaling, which may promote cell proliferation, differentiation, survival, or migration. It is an important molecule in normal kidney development and acts as a key marker in Wilms tumor stem and progenitor cells. Here, we review the structural and genetic features of the CD56 glycoprotein, and summarize its roles in the normal versus diseased metanephric blastema. We discuss areas of CD56-related research that may complement or improve existing Wilms tumor treatment strategies, including the antibody-drug conjugate lorvotuzumab mertansine that binds to CD56...

BACKGROUND: Although tacrolimus (TAC) appeared useful in inducing remission in children with refractory inflammatory bowel disease (IBD) or autoimmune gastroenteropathy (AGE), its use in maintenance therapy remains controversial. The aim of this study was to reveal the potential nephrotoxic nature of prolonged TAC use. METHODS: This retrospective study reviews children with gastrointestinal disorder who underwent kidney biopsy for the evaluation of renal damage during TAC therapy of over one year...
