Cell suspensions of three pathogens were exposed to hydrostatic pressure (HP), bacteriocin mixture (nisin and pediocin) or a combination of HP+bacteriocins and changes in colony forming units (cfu) and cell-morphology by scanning electron microscopy (SEM) were studied. Cell viability loss, as determined from the reduction in cfu before and after a treatment, occurred in Listeria monocytogenes b...

OBJECTIVES We sought to understand the importance of oxidative stress in explaining why the haptoglobin (Hp) genotype determines myocardial infarction (MI) size in diabetes mellitus (DM). BACKGROUND Two common alleles (1 and 2) exist at the Hp locus in humans. The Hp 2 allele is associated with increased MI size in individuals with DM. In vitro, the Hp 2 protein is associated with increased g...

BACKGROUND The association of H.pylori (HP) and insulin resistance degree (IR) has not been evaluated in the diabetic patients so far. In this study, we evaluated the association between HP seropositivity and the homeostatic model assessment for insulin resistance (HOMA-IR) in diabetic patients. METHODS In this study, 211 diabetic patients admitted to the endocrinology clinic of Shahid Behesh...

Introduction: Chronic inflammation and duodenal gastric metaplasia (DGM) increase with the presence of Helicobacter pylori (Hp). DGM is considered the earliest change in the development of duodenal ulcer in children with Hp gastritis. Until now, histopathological duodenal changes in children with Hp associated gastritis had not been studied in Mexico, where there is a high gastric Hp prevalence...

reports dealing with the higher affinity of Hp 2-2, compared with Hp 1-1, for the CD163 receptor on macrophages. The more efficient uptake of the multimeric Hp molecules is reflected in the serum concentrations of free Hb. The observed differences in free Hb between Hp phenotypes could help to explain the previously reported differences in oxidative stress markers among Hp phenotypes (3, 10). I...

The combination of nanoparticles and biological molecules is of intense interest because of the synergistic properties offered by such newly synthesized composites. Heparin (HP), conjugated to nanomaterials, has recently been investigated for its chemical and biological properties. HP has a number of biological activities that can be enhanced when composited with nanoparticles. In addition, HP ...

In vitro observations suggest a role for the mouse heterochromatin protein 1γ (HP-1γ) in the immune system. However, it has not been shown if and how HP-1γ contributes to immunity in vivo. Here we show that in mice, HP-1γ positively regulates the germinal center reaction and high-affinity antibody response to thymus (T)-dependent antigens by limiting the size of CD8(+) regulatory T-cell (Treg) ...

We let Harrington’s Principle, HP, denote the statement that there is a real x such that every x–admissible ordinal is a cardinal in L. Harrington’s proof of “Det(Σ1) implies 0 ] exists” in ZF is done in two steps: first show that Det(Σ1) implies HP and secondly show that HP implies 0 ] exists. We observe that the first step is provable in Z2. In this paper we prove via class forcing that Z2 + ...
