BACKGROUND The aim of the present study was to evaluate the presence of cardiac systolic and diastolic dysfunction in pediatric patients with steroid sensitive nephrotic syndrome (NS). METHODS The study population consisted of 19 patients with debut-relapse of NS aged 1-18 years and 30 sex and age-matched healthy controls. selleck products Blood, urine samples, two M-mode Conventional echocardiogram and Tissue Doppler velocity imaging (TDI) were evaluated in both attack and remission periods RESULTS With regard to conventional pulse wave Doppler (cPWD), steroid sensitive NS patients (both in debut/relapse and in remission periods) had a higher peak of late diastolic flow velocities (A peak) and patients in debut/relapse had a lower E/A ratio than control group indicating diastolic dysfunction (overall p=0.003 and p=0.006, respectively). Based on TDI echocardiography results, patients in debut/relapse had a higher A' and a lower E'/A' ratio (overall p less then 0.001 and p=0.001, respectively). There was also a significant difference in the cPWD E/TDI E' ratio between the patients showing an increased cPWD E/TDI E' ratio in remission compared to in debut/relapse period (p=0.09). The albumin levels were positively correlated with E'/A' and E/ E' ratio (r=0.609; p=0.007, r=0.472; p=0.041 respectively). CONCLUSIONS Systolic cardiac functions are preserved but diastolic functions are affected in steroid sensitive NS patients both in debut/relapse and in remission periods in a relatively short time period. The persistence of LV dysfunction during remission period requires special attention during the follow-up period for early detection of cardiac abnormalities. This article is protected by copyright.

To validate new animal models, a multi-domain panel (battery) approach is essential in that dementia is, by definition, not merely a memory disorder but rather a multi-domain cognitive/behavior disorder animal modeling with a certain type of dementia would develop cognitive impairments in multiple (two at minimum) domains in a specific order according to unique spreading patterns of its neuropathology. In new drug development, the availability of highly sensitive tools assessing animal cognition is crucial to the detection of cognitive decline at the earliest stage of the disease, which may be an optimal time point to test a drug candidate. Using inter-species translatable (analogous) cognitive tasks would also be necessary to successfully predict the efficacy of drug candidates in subsequent clinical trials. Currently, this translational prediction is seriously limited given discrepancies in behavioral assessment methods between animals and humans in the preclinical and clinical trials, respectively. Since neurodegenerative diseases are often accompanied by not only cognitive but also affective and movement disorders, simultaneous assessment of task-relevant locomotor behavior and motivation is also important to rule out the effects of potential confounders. The touchscreen operant platform may satisfy these needs by offering several advantages over conventional methodology. In this review, we discuss the touchscreen operant chamber system and highlight some of its qualities as a promising and desirable tool for translational research of dementia.

In this study we aimed to establish a lncRNAs classifier to improve the accuracy of recurrence prediction for thymic epithelial tumors (TETs). METHODS TETs RNA sequencing (RNA-seq) data set and the matched clinicopathologic information were downloaded from the Cancer Genome Atlas. Using univariate Cox regression and least absolute shrinkage and selection operator (LASSO) analysis, we developed a lncRNAs classifier related to recurrence. Functional analysis was conducted to investigate the potential biological processes of the lncRNAs target genes. The independent prognostic factors were identified by Cox regression model. Additionally, predictive ability and clinical application of the lncRNAs classifier were assessed, and compared with the Masaoka staging by receiver operating characteristic (ROC) analysis and decision curve analysis (Der published by China Lung Oncology Group and John Wiley & Sons Australia, Ltd.OBJECTIVES To document ophthalmic findings, Schirmer's tear test I (STT), and intraocular pressure (IOP) values for anesthetized chimpanzees (Pan troglodytes). ANIMALS STUDIED Ten captive chimpanzees from Zoo Knoxville and Chattanooga Zoo. PROCEDURES Ten chimpanzees were anesthetized for annual physical examinations, blood collection, and ophthalmic examination. Each was anesthetized with intramuscular (IM) injections of dexmedetomidine, midazolam, and ketamine. Ophthalmic findings and STT and IOP values in addition to general health information were recorded for each chimpanzee. Pupillary diameter was measured after topical tropicamide administration. A Shapiro-Wilk test of normality was done for age, weight, STT values, IOP values, and pupil size. RESULTS Ages ranged from 11 to 42 years. Weight range was 40.9-83.6 kg. The mean STT was 13.4 ± 5.3 mm/min. The mean IOP was 14 ± 4.2 mm Hg. Seven of the 10 chimpanzees were considered geriatric, and each had perilimbal lipid deposits. Sedative-associated miosis was successfully counteracted with a regimen of repeated applications of tropicamide, enabling complete fundic examination. CONCLUSIONS A complete ophthalmic examination can be done on anesthetized chimpanzees with the protocol used in this study. © 2020 American College of Veterinary Ophthalmologists.Treatment with the CXCR4 antagonist, plerixafor (AMD3100), has been proposed for clinical use in patients with WHIM (warts, hypogammaglobulinemia, infections, and myelokathexis) syndrome and in pulmonary fibrosis. However, there is controversy with respect to the impact of plerixafor on neutrophil dynamics in the lung, which may affect its safety profile. In this study, we investigated the kinetics of endogenous neutrophils by direct imaging, using confocal intravital microscopy in mouse bone marrow, spleen, and lungs. Neutrophils are observed increasing their velocity and exiting the bone marrow following plerixafor administration, with a concomitant increase in neutrophil numbers in the blood and spleen, while the marginated pool of neutrophils in the lung microvasculature remained unchanged in terms of numbers and cell velocity. Use of autologous radiolabeled neutrophils and SPECT/CT imaging in healthy volunteers showed that plerixafor did not affect GM-CSF-primed neutrophil entrapment or release in the lungs.
