regularized structural equation modeling.a new method is proposed that extends the use of regularization in both lasso and ridge regression to structural equation models. the method is termed regularized structural equation modeling (regsem). regsem penalizes specific parameters in structural equation models, with the goal of creating easier to understand and simpler models. although regularization has gained wide adoption in regression, very little has transferred to models with latent variables. by adding penalties to specific parame ...201627398019
autoantigen-specific immunosuppression with tolerogenic peripheral blood cells prevents relapses in a mouse model of relapsing-remitting multiple sclerosis.dendritic cells (dcs) rendered suppressive by treatment with mitomycin c and loaded with the autoantigen myelin basic protein demonstrated earlier their ability to prevent experimental autoimmune encephalomyelitis (eae), the animal model for multiple sclerosis (ms). this provides an approach for prophylactic vaccination against autoimmune diseases. for clinical application such dcs are difficult to generate and autoantigens hold the risk of exacerbating the disease.201627131971
binding of cfa/i pili of enterotoxigenic escherichia coli to asialo-gm1 is mediated by the minor pilin cfae.cfa/i pili are representatives of a large family of related pili that mediate the adherence of enterotoxigenic escherichia coli to intestinal epithelial cells. they are assembled via the alternate chaperone-usher pathway and consist of two subunits, cfab, which makes up the pilus shaft and a single pilus tip-associated subunit, cfae. the current model of pilus-mediated adherence proposes that cfa/i has two distinct binding activities; the cfae subunit is responsible for binding to receptors of u ...201626975993
epigenetic regulation of spinal cord gene expression contributes to enhanced postoperative pain and analgesic tolerance subsequent to continuous opioid exposure.opioids have become the mainstay for treatment of moderate to severe pain and are commonly used to treat surgical pain. while opioid administration has been shown to cause opioid-induced hyperalgesia and tolerance, interactions between opioid administration and surgery with respect to these problematic adaptations have scarcely been addressed. accumulating evidence suggests opioids and nociceptive signaling may converge on epigenetic mechanisms in spinal cord to enhance or prolong neuroplastic c ...201627094549

developing physical frailty specifications for investigation of frailty pathways in older people.different frailty definitions are suitable for different purposes. when investigating its key multidimensional predictors and effects, narrower definitions of frailty that exclude these elements may be more desirable. for this purpose, candidate physical frailty specifications are constructed and then evaluated on their construct and concurrent validity. for 4638 participants aged 65 to 89 years from wave 2 (2004) of the english longitudinal study of ageing, confirmatory factor analysis is perfo ...201627059656
stability of the encoding plasmids and surface expression of cs6 differs in enterotoxigenic escherichia coli (etec) encoding different heat-stable (st) enterotoxins (sth and stp).enterotoxigenic escherichia coli (etec), one of the most common reasons of diarrhea among infants and children in developing countries, causes disease by expression of either or both of the enterotoxins heat-labile (lt) and heat-stable (st; divided into human-type [sth] and porcine-type [stp] variants), and colonization factors (cfs) among which cs6 is one of the most prevalent etec cfs. in this study we show that etec isolates expressing cs6+sth have higher copy numbers of the cssabcd operon en ...201627054573
a single amino acid substitution prevents recognition of a dominant human aquaporin-4 determinant in the context of hla-drb1*03:01 by a murine tcr.aquaporin 4 (aqp4) is considered a putative autoantigen in patients with neuromyelitis optica (nmo), an autoinflammatory disorder of the central nervous system (cns). hla haplotype analyses of patients with nmo suggest a positive association with hla-drb1* 03:01. we previously showed that the human (h) aqp4 peptide 281-300 is the dominant immunogenic determinant of haqp4 in the context of hla-drb1*03:01. this immunogenic peptide stimulates a strong th1 and th17 immune response. aqp4281-300-speci ...201627054574
synthesis and characterization of a disubstituted piperazine derivative with t-type channel blocking action and analgesic properties.t-type calcium channels are important contributors to signaling in the primary afferent pain pathway and are thus important targets for the development of analgesics. it has been previously reported that certain piperazine-based compounds such as flunarizine are able to inhibit t-type calcium channels. thus, we hypothesized that novel piperazine compounds could potentially act as analgesics.201627053601
inflammatory and neuropathic cold allodynia are selectively mediated by the neurotrophic factor receptor gfrα3.tissue injury prompts the release of a number of proalgesic molecules that induce acute and chronic pain by sensitizing pain-sensing neurons (nociceptors) to heat and mechanical stimuli. in contrast, many proalgesics have no effect on cold sensitivity or can inhibit cold-sensitive neurons and diminish cooling-mediated pain relief (analgesia). nonetheless, cold pain (allodynia) is prevalent in many inflammatory and neuropathic pain settings, with little known of the mechanisms promoting pain vs. ...201627051069
sialylation converts arthritogenic igg into inhibitors of collagen-induced arthritis.rheumatoid arthritis (ra)-associated igg antibodies such as anti-citrullinated protein antibodies (acpas) have diverse glycosylation variants; however, key sugar chains modulating the arthritogenic activity of igg remain to be clarified. here, we show that reduced sialylation is a common feature of ra-associated igg in humans and in mouse models of arthritis. genetically blocking sialylation in activated b cells results in exacerbation of joint inflammation in a collagen-induced arthritis (cia) ...201627046227
substance use and depression symptomatology: measurement invariance of the beck depression inventory (bdi-ii) among non-users and frequent-users of alcohol, nicotine and cannabis.depression is a highly heterogeneous condition, and identifying how symptoms present in various groups may greatly increase our understanding of its etiology. importantly, major depressive disorder is strongly linked with substance use disorders, which may ameliorate or exacerbate specific depression symptoms. it is therefore quite plausible that depression may present with different symptom profiles depending on an individual's substance use status. given these observations, it is important to ...201627046165
recent progress in endothelial progenitor cell culture systems: potential for stroke therapy.endothelial progenitor cells (epcs) participate in endothelial repair and angiogenesis due to their abilities to differentiate into endothelial cells and to secrete protective cytokines and growth factors. consequently, there is considerable interest in cell therapy with epcs isolated from peripheral blood to treat various ischemic injuries. quality and quantity-controlled culture systems to obtain mononuclear cells enriched in epcs with well-defined angiogenic and anti-inflammatory phenotypes h ...201627041632

macrophage-colony stimulating factor derived from injured primary afferent induces proliferation of spinal microglia and neuropathic pain in rats.peripheral nerve injury induces proliferation of microglia in the spinal cord, which can contribute to neuropathic pain conditions. however, candidate molecules for proliferation of spinal microglia after injury in rats remain unclear. we focused on the colony-stimulating factors (csfs) and interleukin-34 (il-34) that are involved in the proliferation of the mononuclear phagocyte lineage. we examined the expression of mrnas for macrophage-csf (m-csf), granulocyte macrophage-csf (gm-csf), granulo ...201627071004
highlights of the 8th international conference on vaccines for enteric diseases: the scottish encounter to defeat diarrheal diseases.infectious diarrhea is a leading cause of morbidity and of mortality; the burden of disease affects individuals of all ages but particularly young children, especially those living in poor regions where the disease is endemic. it is also a health concern for international travelers to these areas. experts on vaccines and enteric infections and advocates for global health improvement gathered in scotland from 8 to 10 july 2015 to discuss recent advances in the assessment and understanding of the ...201626936100
chitosan-based intranasal vaccine against escherichia coli o157:h7.enterohemorrhagic escherichia coli (ehec) o157:h7 is an infectious zoonotic pathogen causing human infections. these infections, in some cases, can lead to hemolytic uremic syndrome and its life-threatening complications and even death worldwide. the first intimate bacterial adhesion, intimin (i), with its own receptor translocated intimin receptor (tir) and e. coli secreted protein a, acting as tir conduit, are highly immunogenic proteins for vaccine development against e. coli o157:h7.201626724233
the autoimmunity-associated gene rgs1 affects the frequency of t follicular helper cells.rgs1 (regulator of g-protein signaling 1) has been associated with multiple autoimmune disorders including type i diabetes. rgs1 desensitizes the chemokine receptors ccr7 and cxcr4 that are critical to the localization of t and b cells in lymphoid organs. to explore how rgs1 variation contributes to autoimmunity, we generated rgs1 knockdown (kd) mice in the nonobese diabetic (nod) model for type i diabetes. we found that rgs1 kd increased the size of germinal centers, but decreased the frequency ...201627029527
oxygen depletion recorded in upper waters of the glacial southern ocean.oxygen depletion in the upper ocean is commonly associated with poor ventilation and storage of respired carbon, potentially linked to atmospheric co2 levels. iodine to calcium ratios (i/ca) in recent planktonic foraminifera suggest that values less than ∼2.5 μmol mol(-1) indicate the presence of o2-depleted water. here we apply this proxy to estimate past dissolved oxygen concentrations in the near surface waters of the currently well-oxygenated southern ocean, which played a critical role in c ...201627029225
social justice and social order: binding moralities across the political spectrum.two studies explored the relationship between political ideology and endorsement of a range of moral principles. political liberals and conservatives did not differ on intrapersonal or interpersonal moralities, which require self-regulation. however differences emerged on collective moralities, which involve social regulation. contrary to moral foundations theory, both liberals and conservatives endorsed a group-focused binding morality, specifically social justice and social order respectively. ...201627031103
