There are numerous reports suggesting that fibroblast activating protein-α (FAP-α) plays an important role in invasion of various tumor types. We studied the expression pattern of FAP-α in esophageal squamous cell carcinoma (ESCC) patients who had not been treated primarily and those who had received neoadjuvant radiochemotherapy. Our goal was to establish whether readily available tissue specimens fixed in formalin and stored in paraffin blocks for years might still be a source of FAP-α RNA for PCR analysis...

Tumor heterogeneity is a major challenge when it comes to treating cancer and also complicates research aimed at determining genetic sources for tumorigenesis. Leveraging high-throughput sequencing technology has been an effective approach for advancing our understanding of genetic diseases, and this type of data can also be used to better understand and make inferences about tumor heterogeneity. Here we describe the basics of genomics data analysis, as well as analysis pipelines for investigating tumor heterogeneity with next-generation sequencing data...

Drought and low water potential induce large increases in Abscisic Acid (ABA ) content of plant tissue. This increased ABA content is essential to regulate downstream stress resistance responses; however, the mechanisms regulating ABA accumulation are incompletely known. Thus, the ability to accurately quantify ABA at high throughput and low cost is important for plant stress research. We have combined and modified several previously published protocols to establish a rapid ABA analysis protocol using gas chromatography-tandem mass spectrometry (GC-MS/MS)...

Rheumatoid arthritis and spondyloarthritis are inflammatory joint disorders with an autoimmune pathogenesis and systemic involvement. The skin is one of the most frequently affected extraarticular sites with a number of manifestations or distinct diseases, including common conditions, such as rheumatoid nodules and psoriasis, and rare diseases like neutrophilic dermatoses. The latter are clinically characterised by polymorphic lesions, including pustules, bullae, abscesses, papules, nodules, plaques and ulcers, and histologically by neutrophil-rich inflammatory infiltrates...

Degeneration of the intervertebral discs is a progressive cascade of cellular, compositional and structural changes that is frequently associated with low back pain. As the first signs of disc degeneration typically arise in the disc's central nucleus pulposus (NP), augmentation of the NP via hydrogel injection represents a promising strategy to treat early to mid-stage degeneration. The purpose of this study was to establish the translational feasibility of a triple interpenetrating network hydrogel composed of dextran, chitosan, and teleostean (DCT) for augmentation of the degenerative NP in a preclinical goat model...

Docetaxel (DTX) and tamoxifen (TMX) are first-line drugs used to treat breast cancer. However when used in combination, they produce antagonism because of their differential metabolic pathways. In order to prevent this antagonism, an amphiphilic copolymer, cholesterol modified hyaruronic acid (HA-CHOL), was synthesized for investigating the co-delivery of TMX and DTX. In vitro drug release experiment of the Co-encapsulated (encapsulated DTX+TMX) nanoparticles (Co-NPs) revealed that NPs with unique release mechanism can markedly reduce the release of these drugs in the circulatory system...

Type 1 cannabinoid (CB1) and dopamine 2 long form (D2L) receptors can physically interact to form heteromers that display unique pharmacology in vitro compared to homomeric complexes. Co-expression of CB1 and D2L and co-application of CB1 and D2 agonists increases cAMP levels while administration of either agonist alone decreases cAMP levels. To understand the observed co-agonist response, our first goal of the current study was to define the stoichiometry of CB1/D2L/Gα protein complexes. Using bioluminescence resonance energy transfer 2 (BRET(2)), we confirmed that, CB1 homodimers, D2L homodimers, and CB1/D2L heteromers are formed...

Coronary artery disease is one of the leading causes of death worldwide. The stenotic coronary vessels are generally treated with coronary artery bypass grafts (CABGs), which can be either arterial (internal mammary artery, radial artery) or venous (saphenous vein). However, the different mechanical properties of the graft can influence the outcome of the procedure in terms of risk of restenosis and subsequent graft failure. In this paper, we perform a computational fluid-structure interaction (FSI) analysis of patient-specific multiple CABGs (Y-grafts) with the aim of better understanding the influence of the choice of bypass (arterial vs venous) on the risk of graft failure...

Genetic engineering of mesenchymal stem cells (MSCs) and neuronal stem cells (NSCs) has been used to treat spinal cord injuries (SCI). As a mechanism of therapy, MSCs secrete high amounts of anti-inflammatory cytokines and trophic factors, while NSCs can differentiate into neuronal lineages and aid in tissue replacement. Additionally, the forced overexpression of secreted proteins can enhance the secretome of transplanted cells, which can increase therapeutic efficacy. This study utilized a combinational treatment consisting of MSCs, NSCs, and the forced overexpression of the chemokine stromal-derived factor-1 (SDF-1) from MSCs (SDF-1-MSCs), to treat a rat model of SCI...

Invasive cervical resorption (ICR) is a type of external resorption that can involve the coronal, middle, and apical parts of the root in its advanced stages. The diagnosis and treatment of ICR depend on the extent of the resorption into the dentin. The treatment of advanced ICR is challenging, and these teeth have poor prognoses. This article describes 4 cases of class 4 ICR diagnosed by using cone-beam computed tomography and treated with a minimally invasive internal approach with sodium hypochlorite irrigation and calcium hydroxide dressing...

A hybrid stochastic-deterministic approach for computing the second-order perturbative contribution E((2)) within multireference perturbation theory (MRPT) is presented. The idea at the heart of our hybrid scheme-based on a reformulation of E((2)) as a sum of elementary contributions associated with each determinant of the MR wave function-is to split E((2)) into a stochastic and a deterministic part. During the simulation, the stochastic part is gradually reduced by dynamically increasing the deterministic part until one reaches the desired accuracy...
