Immunoglobulin A nephropathy (IgAN) is one of the most common glomerular diseases worldwide. Various studies have identified a host of microRNAs (miRNAs) abnormally expressed in IgAN and might affect the pathogenesis and progression of IgAN. However, miR-200bc/429 cluster in the pathopoiesis of IgAN remains poorly understood. For this study, we found that miR-200bc/429 cluster is downregulated in IgAN tissues and IgAN podocytes and HK2 cells compared with their matched controls respectively. In addition, overexpression of miR-200bc/429 cluster in IgAN podocytes and HK2 cells could attenuate the release of inflammatory cytokines MCP-1, IL-6 and RANTES...

There are several barriers to annual hepatitis C virus antibody (HCVAb) testing, including lack of provider knowledge of the changing HCV epidemic and provider underestimation of a patient's risk. We identified low rates of testing for HCVAb in people living with human immunodeficiency virus (HIV) in our outpatient HIV Infectious Diseases clinic, and we developed a quality improvement project to increase rates of HCVAb screening.

Sarcopenia is a complex multifactorial process, some of which involves fat infiltration. Intramyocellular lipid (IMCL) accumulation is postulated to play a role on sarcopenia during aging, which is believed to be due alterations in glucose homeostasis in the skeletal muscle. Sarcopenia, along with intramuscular lipids, is associated with physical inactivity. Resistance training (RT) has been indicated to minimize the age-induced muscle skeletal adaptations. Thus, we aimed to investigate the effects of RT on mRNA levels of regulatory components related to intramyocellular lipid, glucose metabolism and fiber size in soleus and gastrocnemius muscles of aged rats...

Adipose tissue releases bioactive mediators called adipokines. This review focuses on the effects of omentin, vaspin, cardiotrophin-1, Tumor necrosis factor-like Weak Inducer of Apoptosis (TWEAK) and nephroblastoma overexpressed (NOV/CCN3) on obesity and diabetes. Omentin is produced by the stromal-vascular fraction of visceral adipose tissue. Obesity reduces omentin serum concentrations and adipose tissue secretion in adults and adolescents. This adipokine regulates insulin sensitivity, but its clinical relevance has to be confirmed...

TNF-related weak inducer of apoptosis (TWEAK) and TNF-related apoptosis-inducing ligand (TRAIL) are members of TNF superfamily, which has various roles in immunologic and inflammatory reactions in the organism. Pathophysiology in bipolar disorder is still under investigation and altered serum levels of cytokines are often encountered. Aim of this study is to detect serum TWEAK and TRAIL levels of patients with bipolar disorder and healthy controls. For this purpose, 55 patients with bipolar disorder -27 manic episode (ME), 28 remission (RE) and 29 healthy controls (HC) were included...

Oral inhalation (OI) of nano-chemotherapeutics holds great potentials in the treatment of lung cancers as it enables direct targeting of drugs to lung tissues, spatial and temporal control of drug release, and decrease in drug-associated systemic and local lung toxicity. Therefore, the design of chemistry of the nanocarriers and their OI formulations for chemotherapeutics delivery to the peripheral lungs and extrapulmonary tissues of relevance such as lymph nodes, may thus afford new opportunities for treating such relevant diseases...

This article examines the role of testing and innovation in sixteenthcentury Italian pharmacy. I argue that apothecaries were less concerned with testing drugs for efficacy or creating novel products than with reactivating an older Mediterranean pharmacological tradition and studying the materials on which it relied. Their practice was not driven by radical experimentation but by a "culture of tweaking"-of minute operational changes to existing recipes and accommodation of their textual variants-which was rooted in the guild economy fostering incremental over radical innovation and in a humanist reevaluation of past autorities...

Nanocrystalline diamond particles are promising candidates for copious applications in materials science, biology and electronics. In this work, diamond nucleation density was unprecedentedly enhanced via a non-invasive electrostatic self-assembly seeding approach. By addition of glutamic acid to the nanodiamond seeding solution, the positively charged amino-group of glutamic acid, which is adsorbed on nanodiamond particles, enhances the adsorption on negative charged cemented carbide substrate. The highest nucleation density (1...

OBJECTIVES: Urinary levels of TWEAK (uTWEAK) may be correlated with the degree of lupus nephritis (LN) activity. Our objective was to determine the sensitivity and specificity of uTWEAK in Mexican patients with untreated active lupus nephritis. METHODS: An exploratory study was performed; four groups of patients were analyzed as follows: 1) patients with systemic lupus erythematosus (SLE) without renal activity (SLE-LN), 2) patients with SLE with renal activity (SLE+LN), 3) patients with other types of glomerulopathy (glomerulonephritis, GMN), 4) and healthy patients (controls)...

Psoriasis is characterized by keratinocyte resistance to apoptosis. We recently demonstrated an increase in serum tumour necrosis factor-like weak inducer of apoptosis (TWEAK) in patients after topical treatment for psoriasis. We decided to verify whether narrowband ultraviolet B (NB-UVB) has a similar effect. Serum concentration of TWEAK was estimated in patients with exacerbated plaque psoriasis treated with NB-UVB. Baseline TWEAK levels were similar in patients with psoriasis and healthy controls, and Psoriasis Area and Severity Index (PASI) correlated inversely with TWEAK levels...

Complex mass spectrometry based proteomics data sets are mostly analyzed by protein database searches. While this approach performs considerably well for sequenced organisms, direct inference of peptide sequences from tandem mass spectra, i.e., de novo peptide sequencing, oftentimes is the only way to obtain information when protein databases are absent. However, available algorithms suffer from drawbacks such as lack of validation and often high rates of false positive hits (FP). Here we present a simple method of combining results from commonly available de novo peptide sequencing algorithms, which in conjunction with minor tweaks in data acquisition ensues lower empirical FDR compared to the analysis using single algorithms...

The adsorption behaviour of 2H-5,10,15,20-tetraphenyltetrabenzoporphyrin (2HTPTBP) on different metal surfaces, i.e., Ag(111), Cu(111), Cu(110), and Cu(110)-(2 × 1)O was investigated by scanning tunnelling microscopy at room temperature. The adsorption of 2HTPTBP on Ag(111) leads to the formation of a well-ordered two-dimensional (2D) island structure due to the mutual stabilization through the intermolecular π-π stacking and T-type-like interactions of phenyl and benzene substituents of neighboring molecules...

Acute kidney injury (AKI) is characterized by tubular cell death and interstitial inflammation. TWEAK promotes experimental kidney injury and activates the transcription factor NF-κB, a key regulator of genes involved in cell survival and inflammatory response. In search of potential therapeutic targets for AKI, we compared a transcriptomics database of NF-κB-related genes from murine AKI-kidneys with a transcriptomics database of TWEAK-stimulated cultured tubular cells. Four out of twenty-four (17%) genes were significantly upregulated (false discovery rate, FDR<0...

Comparison of small molecules is a common component of many cheminformatics workflows, including the design of new compounds and libraries as well as side-effect predictions and drug repurposing. Currently, large-scale comparison methods rely mostly on simple fingerprint representation of molecules, which take into account the structural similarities of compounds. Methods that utilize 3D information depend on multiple conformer generation steps, which are computationally expensive and can greatly influence their results...

Circadian clocks are innate oscillators that drive daily rhythms in metabolism, physiology, and behavior. 24-h rhythms in gene expression, driven by core clock transcription factors, reflect the epigenetic state of the cell, which in turn is dictated by the metabolic environment. Cancer cells alter their metabolic state and gene expression and therefore are likely to tweak circadian clock function in their favor. Over the past decade, we have witnessed an extraordinary increase in systems-level studies that suggest intricate mechanistic links between the cellular metabolome and the circadian epigenome...

The Common Rule originally issued in 1991 and last amended in 2005 is scheduled to be replaced on January 19, 2018 by a revised Common Rule (the final rule). The goal of the revisions is to modernize and improve applicability of the rule to a research landscape that has dramatically changed since 1991. Translating these changes into action will require comprehensive understanding of the final rule and detailed implementation planning by Human Research Protection Programs. This paper presents select changes that require substantial attention; including for example: expansion of the exempt category, changes to continuing review requirements, changes to the informed consent form and the use of single IRBs for domestic multi-site research...
