Oxidative stress has been implicated as a core contributor to the initiation and progression of multiple neurological diseases. Genetic and environmental factors can produce oxidative stress through mitochondrial dysfunction leading to the degeneration of dopaminergic and other neurons underlying Parkinson disease (PD). Although clinical trials of antioxidants have thus far failed to demonstrate slowed progression of PD, oxidative stress remains a compelling target. Rather than prompting abandonment of antioxidant strategies, these failures have raised the bar for justifying drug and dosing selections and for improving study designs to test for disease modification by antioxidants...

During gestation the developing human fetus is exposed to a diverse range of potentially immune-stimulatory molecules including semi-allogeneic antigens from maternal cells, substances from ingested amniotic fluid, food antigens, and microbes. Yet the capacity of the fetal immune system, including antigen-presenting cells, to detect and respond to such stimuli remains unclear. In particular, dendritic cells, which are crucial for effective immunity and tolerance, remain poorly characterized in the developing fetus...

BACKGROUND: Allergic asthma is a chronic lung disease resulting from inappropriate immune responses to environmental antigens. Early tolerance induction is an attractive approach for primary prevention of asthma. OBJECTIVE: We analysed the mechanisms of perinatal tolerance induction to allergens with particular focus on the role of B cells in preconceptional and early intrauterine immune priming. METHODS: Wild type (WT) and B cell deficient mice received ovalbumin (OVA) intranasally before mating...

The tumor stroma is increasingly recognized as a key player in tumorigenesis through its effects on cell signaling, immune responses, and access of therapeutic agents. A major component of the extracellular matrix is hyaluronic acid (HA), which raises the interstitial gel fluid pressure within tumors and reduces drug delivery to malignant cells, and has been most extensively studied in pancreatic ductal adenocarcinoma (PDA). Pegylated recombinant human hyaluronidase (PEGPH20) is a novel agent that degrades HA and normalizes IFP to enhance the delivery of cytotoxic agents...

The important pathogen vector Dermacentor silvarum is widely distributed in China. However, the tick's adaptation to low winter temperatures remains poorly understood. We therefore investigated the cold hardiness and physiological and biochemical responses of D. silvarum ticks exposed to low temperatures. The results indicated that the lower lethal temperatures (LT50s) for larvae, nymphs, females and males were -16.9°C, -15.8°C, -20.0°C and -20.1°C, respectively. The discriminating temperatures (resulting in 20% survival) for larvae, nymphs, females and males were -18...

Fontan completion, resulting in a total cavopulmonary connection (TCPC), is accomplished using a lateral tunnel (LT), extracardiac conduit (ECC), or recently a bifurcated Y-graft. The local energetic differences between these graft types have not been substantially analyzed under exercise conditions. The present study evaluates the energetic performance of Y-grafts under simulated exercise conditions, compares their performance to the previous LT/ECC Fontan options, and discusses implications for exercise tolerance and hemodynamic predictability...

We aimed to compare Toll-like receptors (TLR) and cytokines expression in local Piau breed and a Commercial line (Landrace×Large White crossbred) pigs in response to vaccination against Pasteurella multocida type D. Seronegative gilts for Pasteurella multocida type D and Mycoplasma hyopneumoniae were used, from which peripheral blood mononuclear cells (PBMC) were collected in four time points (T0, T1, T2 and T3; before and after each vaccination dose). For bronchoalveolar lavage fluid cells (BALF), we set groups of vaccinated and unvaccinated animals for both genetic groups...

Potassium (K+) is the most abundant cation in dental plaque fluid. Previously, we reported the link between K+ transport via Trk2 in Streptococcus mutans and its two critical virulence attributes: acid tolerance and surface adhesion. Herein, we build further on the intimate link between K+ levels and S. mutans biology. High (>25 mM) versus low (≤5 mM) K+ concentrations in the growth medium affected conformational epitopes of cell surface-localized adhesin P1. At low K+, the expression of stress response elements gcrR and codY, cell-adhesion-associated genes such as spaP and metabolism-associated genes such as bglP was induced at stationary phase (P<0...

Harpagophytum procumbens has a long story of use for the treatment of inflammatory diseases. Considering both the antiinflammatory effects of H. procumbens in multiple tissues and the stability of harpagoside in artificial intestinal fluid, the aim of the present study was to explore the possible protective role of a microwave-assisted aqueous Harpagophytum extract (1-1000 μg/mL) on mouse myoblast C2C12 and human colorectal adenocarcinoma HCT116 cell lines, and isolated rat colon specimens challenged with lipopolysaccharide (LPS), a validated ex vivo model of acute ulcerative colitis...

Is non-response to maintenance treatment for recurrent vulvovaginal candidosis (RCVV) related to the impaired glucose metabolism? In the ReCiDiF trial, women with RCVV were given a degressive regimen with fluconazole according to their clinical, microscopic and mycologic response. Data obtained from optimal, suboptimal and non-reponding patients were used for secondary analysis of medical history, physical status and family history for potential glucose impairment. Results were presented in means and percentages...

Numerous countermeasures have been proposed to minimize microgravity-induced physical deconditioning, but their benefits are limited. The present study aimed to investigate whether personalized aerobic exercise based on artificial gravity (AG) mitigates multisystem physical deconditioning. Fourteen men were assigned to the control group (n=6) and the countermeasure group (CM, n=8). Subjects in the CM group were exposed to AG (2Gz at foot level) for 30 min twice daily, during which time cycling exercise of 80-95% anaerobic threshold (AT) intensity was undertaken...

Neisseria meningitidis (the meningococcus) is primarily a commensal of the human oropharynx that sporadically causes septicemia and meningitis. Meningococci adapt to diverse local host conditions differing in nutrient supply, like the nasopharynx, blood, and cerebrospinal fluid, by changing metabolism and protein repertoire. However, regulatory transcription factors and two-component systems in meningococci involved in adaptation to local nutrient variations are limited. We identified novel sibling small regulatory RNAs ( Neisseriametabolic switch regulators [NmsRs]) regulating switches between cataplerotic and anaplerotic metabolism in this pathogen...

Cow's milk allergy is defined as an immunologically mediated adverse reaction to cow's milk proteins and it is usually, along with hen's egg allergy, the first food allergy identified in childhood.One of the main aspects to consider when evaluating the allergenic potential of food proteins is the effect of gastric digestion. It is known that allergens are usually able to survive the harsh acidic environment of the stomach, tolerate the presence of surfactants, and resist digestion by pepsin. They might also be digested into high molecular weight peptide fragments, which retain the same, or sometimes increased, IgE-binding...

Endometriosis is an estrogen-dependent inflammatory disease. The anti-inflammatory cytokine IL-10 is also increased in endometriosis. IL-10 production by Th17 cells is critical for limiting autoimmunity and inflammatory responses. However, the mechanism of inducing IL-10-producing Th17 cells is still largely unknown. The present study investigated the differentiation mechanism and role of IL-10-producing Th17 cells in endometriosis. Here, we report that IL-10(+)Th17 cells are significantly increased in the peritoneal fluid of women with endometriosis, along with an elevation of IL-27, IL-6 and TGF-β...

Hepatorenal syndrome (HRS) is a manifestation of extreme circulatory dysfunction and entails high morbidity and mortality. A new definition has been recently recommended by the International Club of Ascites, according to which HRS diagnosis relies in serum creatinine changes instead that on a fixed high value. Moreover, new data on urinary biomarkers has been recently published. In this sense, the use of urinary neutrophil gelatinase-associated lipocalin seems useful to identify patients with acute tubular necrosis and should be employed in the diagnostic algorithm...

BACKGROUND: One important explanation for the detrimental effects of conventional mechanical ventilation is the biotrauma hypothesis that ventilation may trigger proinflammatory responses that subsequently cause lung injury. This hypothesis has frequently been studied in so-called one-hit models (overventilation of healthy lungs) that so far have failed to establish an unequivocal link between inflammation and hypoxemic lung failure. This study was designed to develop a one-hit biotrauma model...

REVIEW
Ki-Wook Kim, Joo-Hye Song
The lymphatic vasculature has been regarded as a passive conduit for interstitial fluid and responsible for the absorption of macromolecules such as proteins or lipids and transport of nutrients from food. However, emerging data show that the lymphatic vasculature system plays an important role in immune modulation. One of its major roles is to coordinate antigen transport and immune-cell trafficking from peripheral tissues to secondary lymphoid organs, lymph nodes. This perspective was recently updated with the notion that the interaction between lymphatic endothelial cells and leukocytes controls the immune-cell migration and immune responses by regulating lymphatic flow and various secreted molecules such as chemokines and cytokines...

Patients with epidermal growth factor receptor (EGFR)-positive (EGFR(+)) non-small-cell lung cancer (NSCLC) show improved response rates when treated with tyrosine kinase inhibitors (TKIs) such as erlotinib. However, standard daily dosing of erlotinib often does not reach therapeutic concentrations within the cerebrospinal fluid (CSF), resulting in progression of central nervous system (CNS) disease. Intermittent, high-dose administration of erlotinib reaches therapeutic concentrations within the CSF and is well tolerated in patients...

BACKGROUND: MOC31PE immunotoxin was developed to rapidly kill cells expressing the tumor-associated epithelial cell adhesion molecule, which is highly expressed in colorectal cancer. Although cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) may offer long-term survival to patients with peritoneal metastasis from colorectal cancer (PM-CRC), most patients experience disease relapse and novel therapeutic options are needed. On this basis, MOC31PE is being developed as a novel therapeutic principle to target PM-CRC...
