Metastatic rectal adenocarcinoma within haemorrhoids: a case report.

Introduction: Metastatic tumour involvement of the anal canal is rare. Routine pathological evaluation of haemorrhoidectomy specimens has been suggested to be unhelpful and expensive. Selective rather than routine pathological evaluation of haemorrhoidectomy specimens has been recommended.

Periodontal disease in a patient receiving Bevacizumab: a case report.

Introduction: Bevacizumab is a monoclonal antibody that inhibits the action of vascular endothelial growth factor (VEGF) thereby acting as an angiogenesis inhibitor. As a result, supply of oxygen and nutrients to tissues is impaired and tumour cell growth is reduced. Reported side effects due to bevacizumab are hypertension and increased risk of bleeding.

Spectroscopic studies of amphotericin B solubilized in nanoscale bilayer membranes.

Nanodisks (ND) are discrete nanometer scale phospholipid bilayers whose perimeter is circumscribed by amphipathic apolipoproteins. The membranous environment of ND serves as a matrix for solubilizing the polyene antibiotic amphotericin B (AMB). The spectral properties of AMB in ND are dependent upon AMB concentration.

Reconstituted high density lipoprotein enriched with the polyene antibiotic amphotericin B.

The polyene antibiotic amphotericin B (AMB) is an effective antifungal agent whose therapeutic potential is limited by poor aqueous solubility and toxicity toward host tissues. Addition of apolipoprotein A-I to a multilamellar phospholipid vesicle dispersion containing 20% (w/w) AMB induces the formation of reconstituted high density lipoprotein (rHDL), with solubilization of the antibiotic. Density gradient ultracentrifugation resulted in flotation of the complexes to a density of 1.
