Pluripotent stem cells (PSCs) have been described in naïve or primed pluripotent states. Domestic dogs are useful translational models in regenerative medicine, but their embryonic stem cells (cESCs) remain narrowly investigated. Primed-like cESCs expanded in the presence of leukemia inhibitory factor and fibroblast growth factor 2 (LIF-FGF2) acquire features of naïve pluripotency when exposed to chemical inhibitors and LIF (2iL). However, proliferation of cESCs is influenced by the pluripotent state and is comparatively slower than human or mouse PSCs...

Cancer stem cells (CSCs) contribute to multidrug resistance, tumor recurrence and metastasis, making them prime therapeutic targets. Their ability to differentiate and lose stem cell properties makes them challenging to study. Currently, there is no simple assay that can capture and trace the dynamic phenotypic changes on the CSC surface. Here, we report rapid discrimination of breast CSCs from non-CSCs using a nanoparticle-fluorescent-protein based sensor. This nanosensor was employed to discriminate CSCs from non-CSCs, as well CSCs that had differentiated in vitro in two breast cancer models...

Musical rhythm and the grammatical structure of language share a surprising number of characteristics that may be intrinsically related in child development. The current study aimed to understand the potential influence of musical rhythmic priming on subsequent spoken grammar task performance in children with typical development who were native speakers of English. Participants (ages 5-8 years) listened to rhythmically regular and irregular musical sequences (within-participants design) followed by blocks of grammatically correct and incorrect sentences upon which they were asked to perform a grammaticality judgment task...

Footprint is one of the most common types of physical evidence recovered at a crime scene. The forensic footprint evidence may play an important role in establishing the identity of a person; therefore, its examination is of prime importance. A link may be established by observing and comparing the morphological features of footprints with the perpetrator. These barefoot prints may be present as a two-dimensional print or a three-dimensional imprint depending on the substrate upon which they have been impressed upon and accordingly different methods and techniques are implemented in order to identify the questioned prints...

OBJECTIVE: Endovenous thermal ablation in the form of radiofrequency ablation (RFA) or endovenous laser ablation (EVLA) has quickly ascended to a prime position in the treatment of venous insufficiency. While there is good data examining the rates of thrombotic complications, there is a relative paucity of data examining the recanalization rates after endovenous thermal ablation (ETA). METHODS: Data analysis was performed for 1475 thermal ablations in 485 patients from 2012-2015 as a retrospective chart review...

The objective of this study was to innovate an effective oral sustained release hepatoprotective formula for - the water soluble drug - caffeine. Caffeine is rapidly absorbed and eliminated which dictates frequent administration to achieve adequate therapeutic effect. A w/o Pickering emulsion incorporating caffeine in the internal phase was primed. It contained wheat germ oil and was stabilized by synthesized magnesium oxide nanoparticles (MgO NPs). Components selection was based on their antioxidant, hepatoprotective and anticarcinogenic effects...

Platelets play a crucial role in the survival of metastatic cells in the blood circulation. Interaction of tumor cells with platelets leads to the production of plethoric factors among which our review will focus on lysophosphatidic acid (LPA) because platelets are the highest producers of this bioactive lysophospholipid in the organism. LPA promotes platelet aggregation and blocking platelet function leads to inhibition of breast cancer cell metastasis through decreased LPA signaling. Autotaxin (ATX), a lysophospholipase D responsible for basal concentration of LPA in blood, was detected in platelet α-granules...

Standardized uptake value ratios (SUVRs) are commonly used to quantify tracer uptake in amyloid beta positron emission tomography (Aβ-PET). Here, we explore the impact of target and reference region of interest (ROI) selection on SUVR effect size using interventional data from the ongoing Phase Ib PRIME study (NCT01677572) of aducanumab (BIIB037) in patients with prodromal or mild Alzheimer's disease (AD). Methods: Florbetapir PET SUVR was calculated at baseline (screening) and Weeks 26 and 54 for patients randomized to placebo and each of four aducanumab doses (1, 3, 6, and 10 mg/kg), using whole cerebellum, cerebellar grey matter, cerebellar white matter, pons, and subcortical white matter as reference regions...

Coculture systems are widely used in tissue engineering to mimic cell-cell interactions between different populations. This study aimed to find an improved and convenient system for the corneal epithelial differentiation of conjunctiva derived mesenchymal stem cells (CJMSCs). Thus, the cells were used to reconstruct corneal epithelial cells. Obtained by flow cytometry data, 51.9% of isolated CJMSCs were immune reactive for SSEA4+ antibody which are more potent to differentiate into corneal epithelial cells...

Mcl-1 is a highly labile protein, subject to extensive posttranslational regulation. This distinguishes Mcl-1 from other anti-apoptotic proteins and necessitates further study to better understand how interactions with pro-apoptotic Bcl-2 proteins affect its regulation. One such protein, Bim, is known to stabilize Mcl-1, and Bim phosphorylation has been associated with increased Mcl-1 binding. Consequently, we investigated the potential impact of Bim phosphorylation on Mcl-1 stability. We found that Bim stabilizes and primes Mcl-1 in RPCI-WM1 cells and is constitutively phosphorylated...

This study evaluated the accuracy of the lactate minimum test, in comparison to a graded-exercise test and established threshold concepts (OBLA and mDmax) to determine running speed at maximal lactate steady state. Eighteen subjects performed a lactate minimum test, a graded-exercise test (2.4 m·s-1 start,+0.4 m·s-1 every 5 min) and 2 or more constant-speed tests of 30 min to determine running speed at maximal lactate steady state. The lactate minimum test consisted of an initial lactate priming segment, followed by a short recovery phase...

Loading of small RNAs into Argonaute, the core protein in RNA silencing, requires the Hsp70/Hsp90 chaperone machinery. This machinery also activates many other clients, including steroid hormone receptors and kinases, but how their structures change during chaperone-dependent activation remains unclear. Here, we utilized single-molecule Förster resonance energy transfer (smFRET) to probe the conformational changes of Drosophila Ago2 mediated by the chaperone machinery. We found that empty Ago2 exists in various closed conformations...

Type IV pili are expressed by a wide range of prokaryotes, including the opportunistic pathogen Pseudomonas aeruginosa. These flexible fibres mediate twitching motility, biofilm maturation, surface adhesion, and virulence. The pilus is composed mainly of major pilin subunits while the low abundance minor pilins FimU-PilVWXE and the putative adhesin PilY1 prime pilus assembly and are proposed to form the pilus tip. The minor pilins and PilY1 are encoded in an operon that is positively regulated by the FimS-AlgR two-component system...

We present a theory to address the photoluminescence (PL) intensity and valley polarization (VP) dynamics in monolayer WSe$_2$, under the impact of excitonic dark states of both excitons and biexcitons. We find that the PL intensity of all excitonic channels including intravalley exciton (X$_{\rm b}$), intravalley biexciton (XX$_{\rm k,k}$) and intervalley biexciton (XX$_{\rm k,k^\prime}$) in particular for the {XX$_{\rm k,k}$} PL is enhanced by laser excitation fluence. In addition, our results indicate the anomalous temperature dependence of PL, i...

The aim of this paper is discussion of a new middle-range theory of patient safety goal priming via safety culture communication. Bedside nurses are key to safe care, but there is little theory about how organizations can influence nursing behavior through safety culture to improve patient safety outcomes. We theorize patient safety goal priming via safety culture communication may support organizations in this endeavor. According to this theory, hospital safety culture communication activates a previously held patient safety goal and increases the perceived value of actions nurses can take to achieve that goal...

Inflammation is an innate immune response to noxious stimuli to protect the body from pathogens and dangers. Inflammatory responses consist of two main steps: priming and triggering. In priming, inflammatory cells increase expressions of inflammatory molecules, while in triggering, inflammasomes are activated, resulting in cell death and pro-inflammatory cytokine secretion. Inflammasomes are protein complexes comprising intracellular pattern recognition receptors (PRRs) (e.g. nucleotide-binding oligomerization domain-like receptors (NLRs), absent in melanoma 2 (AIM2), and caspases-4/5/11) and pro-caspase-1 with or without a bipartite adaptor molecule ASC...

Rice crop is highly susceptible to the toxic levels of lead (Pb) during early growth stages. Moreover, a sufficient availability of mineral nutrients is critical for survival of plants particularly under stressful conditions. An experiment was carried out to unravel the coordinated effects of Pb stress (1-mM PbCl2 ) and different nutrient treatments (sufficient nutrient supply, nitrogen (N) deprivation, phosphorus (P) deprivation, and potassium (K) deprivation) on morphological growth, reactive oxygen species (ROS), antioxidants, and nutrient status in primed and non-primed rice seedlings...
