BACKGROUND: Classic galactosemia results from deficient activity of galactose-1-phosphate uridylyltransferase (GALT), a key enzyme of galactose metabolism. Despite early diagnosis and early postnatal therapeutic intervention, patients still develop neurologic and fertility impairments. Prenatal developmental toxicity has been hypothesized as a determinant factor of disease. In order to shed light on the importance of prenatal GALT activity, several studies have examined GALT activity throughout development...

Haemophilus parasuis is the causative agent of Glasser's disease in pigs. Cytolethal distending toxin (CDT) is an important virulence factor of H. parasuis. It is composed of three subunits: CdtA, CdtB and CdtC and all were successfully expressed in soluble form in Escherichia coli when the signal peptides were removed. Purified CdtB had DNase activity, i.e. caused DNA double strand damage, in vitro and in vivo prior to cell arrest and apoptosis. Flow cytometry analysis showed CdtB alone could induce cell cycle arrest and apoptosis in PK-15 porcine kidney and pulmonary alveolar macrophage (PAM) cells, which could be enhanced by CdtA or/and CdtC...

Several studies have shown Dengue Virus (DENV) nucleic acids and/or antibodies present in Neotropical wildlife including bats, suggesting that some bat species may be susceptible to DENV infection. Here we aim to elucidate the role of house-roosting bats in the DENV transmission cycle. Bats were sampled in households located in high and low dengue incidence regions during rainy and dry seasons in Costa Rica. We captured 318 bats from 12 different species in 29 households. Necropsies were performed in 205 bats to analyze virus presence in heart, lung, spleen, liver, intestine, kidney, and brain tissue...

Lymphedema distichiasis syndrome (LDS) is a rare, autosomal dominant genetic condition, characterized by lower limb lymphedema and distichiasis. Other associated features that have been reported include varicose veins, cleft palate, congenital heart defects, and ptosis. We update a previously reported family with a pathogenic variant in FOXC2 (c.412-413insT) where five affected individuals from the youngest generation had congenital renal anomalies detected on prenatal ultrasound scan. These included four fetuses with hydronephrosis and one with bilateral renal agenesis...

REVIEW
Yijen L Wu, Cecilia W Lo
Small animal models, particularly mouse models, of human diseases are becoming an indispensable tool for biomedical research. Studies in animal models have provided important insights into the etiology of diseases and accelerated the development of therapeutic strategies. Detailed phenotypic characterization is essential, both for the development of such animal models and mechanistic studies into disease pathogenesis and testing the efficacy of experimental therapeutics. MRI is a versatile and noninvasive imaging modality with excellent penetration depth, tissue coverage, and soft tissue contrast...

T cell depletion is widely used as induction therapy in solid organ transplants and particularly in kidney transplantation, to reduce the episodes of acute cellular rejection. The resultant reduction in T cell numbers is usually temporary, as T cells are actively replenished due to thymic output and/or lymphopenia-induced proliferation of remaining, depletion-resistant T cells. However, the extent of T cell replenishment and the persistence of lymphopenia varies between individuals, with potential impacts on protective or pathogenic immune responses...

AIM: Little is known about how toll-like receptor 4 (TLR4) influences the renal microvasculature. We hypothesized that acute TLR4 stimulation with lipopolysaccharide (LPS) impairs afferent arteriole autoregulatory behaviour, partially through reactive oxygen species (ROS). METHODS: We assessed afferent arteriole autoregulatory behaviour after LPS treatment (1 mg kg(-1) ; i.p.) using the in vitro blood perfused juxtamedullary nephron preparation. Autoregulatory behaviour was assessed by measuring diameter responses to step-wise changes in renal perfusion pressure...

AIMS: Increases in the systemic vasodilator adrenomedullin and the renal vasoconstrictors thromboxane A2 (TXA2 ) in cirrhotic patients are pathogenic factors for the development of functional acute-kidney-injury, including pre-renal azotemia (PRA) and hepatorenal syndrome (HRS), which is associated with high mortality. This study aims to find biomarkers which can diagnose HRS in early stage for treating it as soon as possible. METHODS: Acute decompensated cirrhotic patients who had been admitted to hospital were enrolled in this prospective cohort study...

BACKGROUND: Survival for patients commencing renal replacement therapy is around 90% in the first year and 83% at two years after starting dialysis. The factors that appear to predict mortality are comorbidity and frailty associated with kidney disease, glomerular filtration rate, age and biochemical factors. OBJECTIVES: To analyse the condition of patients starting renal replacement therapy, based on biomarkers commonly used in clinical practice and their association with mortality, measured 6 and 12 months after initiating replacement therapy...

A series of 2-aminoaryl-7-arylbenzoxazole derivatives have been designed, synthesized and evaluated as anti-cancer agents. Fourteen of the compounds exhibited cytotoxic effects towards Human A549 lung cancer cells. We found 12l was the most potent with an EC50 of 0.4 μM, equivalent to the anti-cancer drug doxorubicin, but had low selectivity following cross screening in monkey kidney Vero cells. Eight of the most potent or most selective compounds were further profiled in additional cell lines (MCF7, NCI-H187 and KB) to better understand their cytotoxic activity...

Ischaemia-reperfusion injury (I/RI) is a common cause of acute kidney injury (AKI). The molecular basis underlying I/RI-induced renal pathogenesis and measures to prevent or reverse this pathologic process remains to be resolved. Basic fibroblast growth factor (FGF2) is reported to have protective roles of myocardial infarction as well as in several other I/R related disorders. Herein we present evidence that FGF2 exhibits robust protective effect against renal histological and functional damages in a rat I/RI model...

AIM: The Kidney Disease Improving Global Outcomes (KDIGO) guideline recommends the incorporation of a new risk calculator that quantifies the end stage kidney disease (ESKD) risk based on a composite profile of risk factors in living kidney donor candidates (LKDCs). We compared the ESKD risk estimates in previously declined versus accepted LKDCs to evaluate the predictive capacity and potential impact of this tool. METHODS: Baseline 15-year and lifetime ESKD risk estimates without donation were calculated using the risk calculator for LKDCs assessed from two centres between 2007 and 2015...

REVIEW

The delicate balance of risk vs. benefit of using antiplatelet and antithrombotic agents in the general population is well established. The decision to use these agents in the end stage renal disease (ESRD) population remains complex and difficult. The concomitant association of a prothombotic state with high risk of bleeding in the ESRD population requires individualization and careful clinical judgment before implementing such therapy. There remains a paucity of clinical trials and lack of substantial evidence in literature for safe and effective use of antithrombotic drugs in patients with advanced chronic kidney disease...
