Aims: Having shown that Lumacaftor rescued the hERG trafficking defect in the induced pluripotent stem cell-derived cardiomyocytes (iPSC-CMs) of two LQT2 patients, we tested whether the commercial association Lumacaftor + Ivacaftor (LUM + IVA) could shorten the QTc in the same two patients. Methods and results: After hospital admission and 1 day of baseline recordings, half dose LUM + IVA was administered on Day 1, followed by full dose (LUM 800 mg + IVA 500 mg) for 7 days...

BACKGROUND: It has been reported that chronic inflammation may play an important role in the pathogenesis of several serious diseases and could be modulated by diet. Recently, the Dietary Inflammatory Index (DII® ) was developed to assess the inflammatory potential of the overall diet. The DII has been reported as relevant to various diseases but has not been validated in Japanese. Thus in the present study, we analyzed the relationship between DII scores and high-sensitivity C-reactive protein (hs-CRP) levels in a Japanese population...

BACKGROUND: Neo-vascularization, an indispensible phenomenon for tissue regeneration, facilitates repair and remodeling of wound tissues. This process is impaired in chronic wounds due to reduced number and recruitment of endothelial cells (ECs), thereby necessitating development of newer strategies to enhance the EC repertoire as a therapeutic approach. METHODS: We explored the 'plasticity' of Wharton's jelly derived-mesenchymal stromal cells (WJ-MSCs) using an anti-inflammatory drug-mediated enhanced trans-differentiation into ECs, based on our observation of temporal decrease in COX-2 expression during trans-differentiation of MSCs into ECs at day 7 and 14 along with mature ECs...

BACKGROUND: Certain foods and dietary patterns have been associated with both inflammation and frailty. As chronic inflammation may play a role in frailty and disability, we examined the association of the inflammatory potential of diet with these outcomes. METHODS: Data were taken from 1948 community-dwelling individuals ≥60 years old from the Seniors-ENRICA cohort, who were recruited in 2008-2010 and followed-up through 2012. Baseline diet data, obtained with a validated diet history, was used to calculate Shivappa's Dietary Inflammatory Index (DII), an "a priori" pattern score which is based on known associations of foods and nutrients with inflammation, and Tabung's Empirical Dietary Inflammatory Index (EDII), an "a posteriori" pattern score which was statistically derived from an epidemiological study...

We identified a morphologically uncommon piscine retractor lentis muscle in the yellowfin goby Acanthogobius flavimanus. This lentis muscle has a shape similar to the Greek small letter lambda (λ). The two legs of the muscle are attached to the retinal periphery at the ventral eyecup, while the tip is connected to the lens surface by a ligament. Scanning electron microscopy showed that the fibers of the lentis muscle run along the length of both the anterior and posterior legs. Immunolabeling with antiacetylated tubulin antibody and neuronal tracing with DiI of the whole lentis muscle revealed that the anterior leg is innervated by one or more nerves...

Calcium-dependent inactivation (CDI) is a fundamental autoregulatory mechanism in CaV 1 and CaV 2 voltage-gated calcium channels. Although CDI initiates with the cytoplasmic calcium sensor, how this event causes CDI has been elusive. Here, we show that a conserved selectivity filter (SF) domain II (DII) aspartate is essential for CDI. Mutation of this residue essentially eliminates CDI and leaves key channel biophysical characteristics untouched. DII mutants regain CDI by placing an aspartate at the analogous SF site in DIII or DIV, but not DI, indicating that CaV SF asymmetry is key to CDI...

This protocol was developed to assess communication in tumor cells and to provide a dependable and standardized assay for the in vitro determination of gap junction function. The method is noninvasive; in this method, the cell population under study is divided such that 1 fraction is loaded with a lipophilic cell plasma membrane permeable dye, calcein acetoxymethyl ester, that is hydrolyzed upon cellular uptake by cytoplasmic esterases to yield calcein, a fluorescent and membrane-impermeable molecule. The other fraction is loaded with 1,1'-dioctadecyl-3,3,3',3' tetramethylindodicarbocyanine perchlorate (DiD)/1,1'-dioctadecyl-3,3,3',3'-tetramethylindocarbocyanine perchlorate [Dil; DilC18 (3)], which is a lipophilic membrane dye that diffuses laterally to stain the entire cell membrane, is impermeable, and attains an orange-red fluorescence upon incorporation into membranes...

BACKGROUND: Recent evidence suggests that pro-inflammatory states may be independently associated with the risk of suicidality, above and beyond depression. This study assesses whether four indicators of inflammation, circulating levels of C-reactive protein (CRP), white blood cell (WBC) count and immunoglobulin E (IgE), and dietary inflammatory potential, measured using the Dietary Inflammatory Index® (DII), distinguish suicidal ideation (SI) from major depression (MD). METHODS: Data come from multiple cycles of the US National Health and Nutrition Examination Survey (NCRP&WBC   = 13,912; NDII   = 17,076; NIgE   = 4,060)...

Our previous studies showed that the early use of calpain inhibitors reduces calpain activity in multiple brain regions, and that postnatal treatment with calpeptin may lead to cerebellar motor dysfunction. However, it remains unclear whether postnatal calpeptin application affects hippocampus-related behaviors. In this study, Sprague-Dawley rats were purchased from the Animal Center of Anhui Medical University of China. For the experiments in the adult stage, rats were intraperitoneally injected with calpeptin, 2 mg/kg, once a day, on postnatal days 7-14...

Neural insult during development results in recovery outcomes that vary dependent upon the system under investigation. Nerve regeneration does not occur if the rat gustatory chorda tympani nerve is sectioned (CTX) during neonatal (≤ P10) development. It is unclear how chorda tympani soma and terminal fields are affected after neonatal CTX. The current study determined the impact of neonatal CTX on chorda tympani neurons and brainstem gustatory terminal fields. To assess terminal field volume in the nucleus of the solitary tract (NTS), rats received CTX at P5 or P10 followed by chorda tympani label, or glossopharyngeal (GL) and greater superficial petrosal (GSP) label as adults...

Bone marrow (BM)-derived endothelial progenitor cells (EPCs) are the key players in angiogenesis and vascular function. Cystathionine-β-synthase (CBS), an H2 S-generating enzyme in methionine metabolism, regulates the function of these EPCs. This study aims to examine whether CBS hyper-methylation contributes to the bone marrow endothelial progenitor cell (BM-EPCs) function and subsequent bone blood flow in mice fed with a high methionine diet (HMD). Bone marrow (BM) cells were collected from HMD and control mice, differentiated into BM-EPCs, and were characterized by acLDL-DiI labeling...

BACKGROUND: Proprotein convertase subtilisin/kexin type 9 (PCSK9) has been found to play a major role in atherosclerotic cardiovascular disease (ASCVD) by promoting hyperlipidemia. Its inhibition has therefore emerged as a viable drug target for improving the outcome of ASCVD. However, current monoclonal antibody PCSK9 inhibitors are considered cost ineffective and there is the need to discover new effective and cheaper small molecule alternatives. PURPOSE: The methanolic and ethanolic crude extracts of Nauclea latifolia have been shown to possess anti-hyperlipidemic activity, but the chemical component(s) responsible for this activity and the mechanism of action have remained unknown...

Dorsoventrality in leaves has been shown to depend on the pre-patterned expression of KANADI and HD-ZIPIII genes within the plant shoot apical meristem (SAM). However, it has also been proposed that asymmetric auxin levels within initiating leaves help establish leaf polarity, based in part on observations of the DII auxin sensor. By analyzing and quantifying the expression of the R2D2 auxin sensor, we find that there is no obvious asymmetry in auxin levels during Arabidopsis leaf development. We further show that the mDII control sensor also exhibits an asymmetry in expression in developing leaf primordia early on, while it becomes more symmetric at a later developmental stage as reported previously...

BACKGROUND: Telomeres are repeats of DNA that contain the sequence TTAGGG at the ends of each chromosome, and their function is to protect DNA from damage. Little evidence exists regarding the relationship between dietary patterns and telomere length, especially derived applying longitudinal design. The aim was to study if overall dietary pattern is associated with leukocyte telomere length (LTL) or faster telomere attrition or both. METHODS: The setting was longitudinal and observational...
