Native C-reactive protein (CRP) is composed of five identical subunits arranged in a pentameric structure (pCRP). Binding of pCRP to damaged cell membranes produces a second isoform, modified CRP, which has similar antigenicity to isolated monomeric subunits of CRP (mCRP). Emerging evidence indicates that modified CRP plays a role in ...

Accumulation of microdamage in aging and disease can cause skeletal fragility and is one of several factors contributing to osteoporotic fractures. To better understand the role of microdamage in fragility fracture, the mechanisms of bone failure must be elucidated on a tissue-level scale where interactions between bone matrix properties, the ...

Increased expression of DNA repair genes contributes to the extreme resistance shown by melanoma to conventional DNA-damaging chemotherapeutics. One such chemotherapeutic effective against a range of other cancers, but not melanoma, is cisplatin. The DNA repair protein, ERCC1, is needed to remove cisplatin-induced DNA damage. We have shown that ERCC1 ...

Hormones, and hormone responses to social contexts, are the proximate mechanisms of evolutionary pathways to pair bonds and other social bonds. Testosterone (T) is implicated in tradeoffs relevant to pair bonding, and oxytocin (OT) and arginine vasopressin (AVP) are positively tied to social bonding in a variety of species. Here, ...

Gangliogliomas are rare tumors of the central nervous system, usually containing neoplastic ganglion cells and astrocytic components. Few cases of ganglioglioma containing only oligodendrocytic tissue have been reported to date. We present a case of a 40-year-old woman with ganglioglioma consisting mostly of oligodendroglial components. Magnetic resonance imaging showed a ...

Haematogones are normal, maturing B-cell precursors. They can be confused with neoplastic immature lymphoid cells of B lymphoblastic leukaemia/lymphoma or B-cell acute lymphoblastic leukaemia (B-ALL). Though multi-colour flow-cytometry strategies for distinguishing haematogones from cells of B-ALL are well-described, similar strategies have not been determined for bone marrow trephine biopsies (BMTB). ...

BACKGROUND: Recent experience with the ipsilateral TRAM flap has shown that it has the advantage of a longer functional pedicle length, which allows tension-free inset of well-vascularized tissue into the breast pocket. This leads to better positioning and shaping of the reconstructed breast with minimal disruption of the inframammary fold. ...

Vascular graft infections are associated with the potential for devastating sequelae, including hemorrhage, septicemia, amputation, and death. Graft excision and debridement of the infected bed with revascularization via an extra-anatomic site or orthotopic vein bypass has been the traditional treatment of choice. Because the morbidity of these operations is substantial, ...

Abstract We report the fabrication and characterization of new self-assembled monolayers (SAMs) formed from dihexadecyldithiophosphinic acid ((C16)2DTPA) molecules on gold substrates. In these SAMs, the ability of the (C16)2DTPA head group to chelate to the gold surface depends on the morphology of the gold substrate. Gold substrates fabricated by e-beam ...

Foxp3+CD4+ regulatory T (T(reg)) cells are a key population in controlling the immune response. Recently, their roles have been expanded to broader, non-immune, contexts, in particular the metabolic consequences downstream of obesity-induced inflammation, e.g. type-2 diabetes and cardiovascular disease. This review highlights the major innate and adaptive immune cell subsets ...

We report the case of a 53-year-old hemodialysis patient with severe aortic stenosis, who developed acute systemic hypoperfusion after arteriovenous fistula (AVF) construction. He presented with hypotension and repeated syncope soon after distal radiocephalic AVF construction, and finally developed a respiratory arrest. His blood pressure and hemodynamics recovered promptly by ...

Current evidence indicates that rises in systemic levels of estrogen create in the uterus an inhibitory environment for sympathetic nerves. However, molecular insights of these changes are far from complete. We evaluated if semaphorin 3F mRNA, a sympathetic nerve repellent, was produced by the rat uterus and if its expression ...

HSulf-1 gene encodes an extracellular 6-O-endosulfatase and regulates the sulfation status of heparan sulfate proteoglycans (HSPGs). We have demonstrated that promoter hypermethylation correlates with the HSulf-1 silencing in gastric cancer. To investigate the functional importance of the HSulf-1 silencing in gastric cancer, we restored the HSulf-1 expression in gastric cancer ...

In the 1990s, there was a lack of information on patient doses in most developing countries. In 2004, the International Atomic Energy Agency initiated projects aimed at assessing 'how safe are patients in radiological procedures and how to make them safer'. The major obstacle was a lack of medical physicists ...
