Cardiovascular disease is the number one cause of death globally. Poor diet constitutes a key factor in the initiation and progression of cardiovascular disease and has become the leading risk factor for disability and death worldwide. Therefore, addressing suboptimal nutrition is of key prognostic relevance in primary and secondary prevention of metabolic vascular syndrome.Metabolic vascular syndrome is a multidimensional network of acquired cardiometabolic risk factors closely related to insulin resistance (IR) and concomitant hyperinsulinemia...

The current work aims to explore the thermodynamic and conformational aspects for the binding of fluoroquinolone antibacterial drug, levofloxacin (LFC), with bovine serum albumin (BSA) using calorimetric, spectroscopic (UV-visible, fluorescence, circular dichroism, and (1)H NMR), dynamic light scattering (DLS) and computational methods (molecular docking). The binding of LFC with BSA at two sequential sites with higher affinity (~10(3)M(-1)) at the first site has been explored by calorimetry whereas the binding at a single site with affinity of the order of ~10(4)M(-1) has been observed from fluorescence spectroscopy...

Antiretroviral therapy (ART) suppresses viral replication in HIV-infected individuals but does not eliminate the reservoir of latently infected cells. Recent work identified PD-1(+) follicular helper T (Tfh) cells as an important cellular compartment for viral persistence. Here, using ART-treated, SIV-infected rhesus macaques, we show that CTLA-4(+)PD-1(-) memory CD4(+) T cells, which share phenotypic markers with regulatory T cells, were enriched in SIV DNA in blood, lymph nodes (LN), spleen, and gut, and contained replication-competent and infectious virus...

For endocytosis and exocytosis, membranes transition among planar, budding, and vesicular topographies through nanoscale reorganization of lipids, proteins, and carbohydrates. However, prior attempts to understand the initial stages of nanoscale bending have been limited by experimental resolution. Through the implementation of polarized localization microscopy, this article reports the inherent membrane bending capability of cholera toxin subunit B (CTxB) in quasi-one-component-supported lipid bilayers. Membrane buds were first detected with <50 nm radius, grew to >200 nm radius, and extended into longer tubules with dependence on the membrane tension and CTxB concentration...

It is increasingly appreciated that alternative splicing plays a key role in generating functional specificity and diversity in cancer. However, the mechanisms by which cancer mutations perturb splicing remain unknown. Here, we developed a network-based strategy, DrAS-Net, to investigate more than 2.5 million variants across cancer types and link somatic mutations with cancer-specific splicing events. We identified more than 40,000 driver variant candidates and their 80,000 putative splicing targets deregulated in 33 cancer types and inferred their functional impact...

HAb18G/CD147, an important marker in the progression of hepatocellular carcinoma (HCC), is highly expressed on the surface of HCC cells. To increase the therapeutic efficacy of Doxil (PEGylated liposomal doxorubicin) against HCC, we constructed CD147-targeted doxorubicin-loaded immunoliposomes (Anti-CD147 ILs-DOX) by conjugating F(ab')2 of a CD147-specific monoclonal antibody to DSPE-PEG-MAL, and then inserted the antibody-conjugated polymer to Doxil. Anti-CD147 ILs-DOX delivered DOX to CD147-overexpressing HCC cells specifically and efficiently in vitro and in vivo, resulting in enhanced therapeutic effects than non-targeted controls...

Objectives: HCQ has been described as having a beneficial effect in patients with APS but its mechanism of action is unclear. We hypothesized that HCQ may have effects on subnormal angiogenesis, inflammation and haemostatic biomarkers seen in APS. The aim of our study was to assess laboratory markers [annexin A5 (AnxA5) anticoagulant activity, tissue factor (TF) levels, thromboelastography (TEG), CRP, Bb, C3a and VEGF] in HCQ-naïve patients with aPL at baseline and after commencing HCQ...

Ample evidence supports a neurodevelopmental origin in some cases of schizophrenia (SZ). More inconsistent information is available for bipolar disorder (BD). We herein review studies with a focus on premorbid (adjustment and functionality) and early developmental milestones that include both SZ and BD patients. A search was performed in the PubMed electronic database, retrieving 619 abstracts; 30 were ultimately included in this systematic review. Eight prospective cohorts, 15 retrospective studies, and 7 studies based on national registries...

Transcriptomic data have become a fundamental resource for stem cell (SC) biologists as well as for a wider research audience studying SC-related processes such as aging, embryonic development and prevalent diseases including cancer, diabetes and neurodegenerative diseases. Access and analysis of the growing amount of freely available transcriptomics datasets for SCs, however, are not trivial tasks. Here, we present StemMapper, a manually curated gene expression database and comprehensive resource for SC research, built on integrated data for different lineages of human and mouse SCs...

Background: Kidney injury molecule-1 (KIM-1) and neutrophil gelatinase-associated lipocalin (NGAL) are promising biomarkers for monitoring delayed graft function (DGF) after kidney transplantation. Here we investigated localization and distribution of KIM-1 and NGAL staining in renal allograft biopsies and studied their association with histological features, functional DGF (fDGF) and the tubular function slope (TFS), a functioning proximal tubular epithelial cell (PTEC) marker. Methods: Day 10 protocol biopsies of 64 donation after circulatory death recipients were stained for KIM-1 and NGAL and the positive area was quantified using ImageJ software...

Plant immunity is initiated by extracellular detection of pathogen-associated molecular patterns (PAMPs) through surface-localized pattern recognition receptors (PRRs). PRR activation induces many responses including the activation of mitogen-activated protein kinases (MAPKs) that ultimately limit bacterial growth. Previous work identified Arabidopsis MAP kinase phosphatase 1 (MKP1) as a negative regulator of signaling pathways required for some, but not all, of PAMP-initiated responses. Specifically, loss of MAPK MPK6 in an mkp1 background suppressed a subset of the mkp1-dependent biological phenotypes, indicating the requirement for MPK6 in MKP1-dependent signaling...

Leaffooted plant bugs (LFPBs) (Leptoglossus spp., Guérin-Méneville) (Hemiptera: Coreidae) are large seed-feeding bugs native to the Western Hemisphere. In California, several Leptoglossus spp. feed on almonds, pistachios, and pomegranate and are occasional pests. The objective of this study was to survey the different species of Leptoglossus present in almond, pistachio, and pomegranate orchards in the Central Valley of California. We used two molecular markers, amplified fragment length polymorphisms (AFLPs) and mitochondrial DNA COI, to determine the number of species or strains of each species, and to infer whether individuals of each species move and possibly interbreed with populations from the other host plants...

Aims: The co-stimulatory receptor CD27 modulates responses of T cells, B cells, and NK cells. Various T cell subsets participate in atherogenesis. However, the role of CD27 in atherosclerosis remains unexplored. Methods and results: Here we investigated the effect of bone marrow-derived and systemic CD27 deficiency in Apolipoprotein E-deficient (Apoe-/-) mice in early and advanced stages of atherosclerosis. Lethally-irradiated Apoe-/- mice reconstituted with Cd27-/-Apoe-/- bone marrow and consuming an atherogenic diet displayed a markedly increased plaque size and lesional inflammation compared to mice receiving Cd27+/+Apoe-/- bone marrow...

Metallothionein (MT) family are cysteine-rich proteins that regulate zinc (Zn) homeostasis and protect against oxidative damage. Studies in transgenic mice have shown that MT favourably influence longevity, although their role in human aging is not completely understood.Within the European multicenter study MARK-AGE, we analysed MT induction after Zn treatment in peripheral blood mononuclear cells (PBMCs) and its relation with redox biomarkers in 2936 age-stratified subjects (35-75 years) including the general population (RASIG), centenarian offspring (GO) and their spouses (SGO)...

Background: Gamma (30-80 Hz) and high-gamma (80-200 Hz) thalamocortical EEG rhythms are involved in conscious processes and are attenuated by isoflurane and propofol. To explore the hypothesis that this attenuation is a correlate of anaesthetic action, we characterized the effect dexmedetomidine, a selective adrenergic α-2 agonist with lesser hypnotic potency, on these rhythms. Methods: We recorded local field potentials from barrel cortex and ventroposteromedial thalamic nucleus in ten previously instrumented rats to measure spectral power (30-50 Hz, 51-75 Hz, 76-125 Hz, 126-200 Hz bands) during baseline, at four dexmedetomidine plasma concentrations obtained by i...
