BACKGROUND The prevalence of spondyloarthritis (SpA) varies across populations. In Mexicans, the prevalence of SpA is still unknown. OBJECTIVE The objective of this study was to determine the prevalence of SpA in the community as well as that of inflammatory back pain (IBP) and ankylosing spondylitis (AS). METHODS We identified individuals older than 18(More)
Epidermal Growth Factor chemically conjugated to P64k carrier protein from Neisseria meningitidis emulsified in Montanide ISA 51 adjuvant is a cancer vaccine under clinical evaluation. We explored the influence of priming and boosting variables on the antibody response in mice. An apparently low dose fractionated in multiple anatomical sites at priming(More)
Cancer vaccines efficacy may improve inducing a rapid and persistent immune response, early at diagnosis along with standard therapies. EGF chemically conjugated to the carrier protein P64k from Neisseria meningitidis in montanide ISA 51 adjuvant is under evaluation, aiming to stimulate a B-cell response. High-dose cyclophosphamide and doxorubicin after(More)
Despite promising results in the use of anti-epidermal growth factor receptor (EGFR) Abs for cancer therapy, several issues remain to be addressed. An increasing emphasis is being placed on immune effector mechanisms. It has become clear for other Abs directed to tumor targets that their effects involve the adaptive immunity, mainly by the contribution of(More)
BACKGROUND/OBJECTIVE Electronic cigarette (E-cigarettes) emissions present a potentially new hazard to neonates through inhalation, dermal and oral contact. Exposure to nicotine containing E-cigarettes may cause significant systemic absorption in neonates due to the potential for multi-route exposure. Systemic absorption of nicotine and constituents of(More)
METHODS Timed-pregnant C57BL/6J mice were exposed to 2.4% nicotine in propylene glycol (PG) or 0% nicotine /PG once a day from gestational day 15 until delivery. After delivery, offspring and mothers were exposed to E-cigarette vapors for an additional 14 days from postnatal day 2 through 16. Following their last exposure serum cotinine levels were measured(More)
UNLABELLED Hyperoxia exposure can inhibit alveolar growth in the neonatal lung through induction of p21/p53 pathways and is a risk factor for the development of bronchopulmonary dysplasia (BPD) in preterm infants. We previously found that activation of nuclear factor erythroid 2 p45-related factor (Nrf2) improved survival in neonatal mice exposed to(More)
Primary lymphoma of the urinary bladder is exceedingly rare, representing 0.2% of all extranodal non-Hodgkin's lymphoma. Although Matsuno et al. and others state the most common type is mucosa-associated lymphoid tissue (MALT) lymphoma, 20% of all the primary lymphomas of the urinary bladder are considered to be high grade neoplasms; the majority being(More)
Investigations detailed herein, including density functional theory (DFT) calculations, demonstrate that the formation of either alkoxy- or hydroxy-Ti(III) complexes considerably decreases the energy of activation for C-O bond homolysis. As a consequence of this observation, we described two new synthetic applications of Nugent's reagent in organic(More)
EGFR [EGF (epidermal growth factor) receptor] overexpression correlates with poor prognosis and bad outcomes in different tumours. However, evidence for EGFR contribution in melanoma immunobiology is limited. We have expressed the full-length human EGFR gene in a murine melanoma cell line. EGFR protein expression in stably trnasfected B16 cells in culture(More)
