Cytotoxic T lymphocytes (CTLs) are highly effective serial killers capable of destroying virally infected and cancerous targets by polarized release from secretory lysosomes. Upon target contact, the CTL centrosome rapidly moves to the immunological synapse, focusing microtubule-directed release at this point [1-3]. Striking similarities have been noted(More)
Exorex is a new topical formulation for the treatment of psoriasis; it contains 1% coal tar and a synthetic analogue resembling components identified in banana skin (a complex of esterified essential fatty acids). To determine whether the esterified essential fatty acid complex confers any therapeutic advantage over coal tar alone, patients with chronic(More)
Oligonucleotide probes containing multiple non-radioactive labels have been prepared by utilising and extending the methods used to prepare polyamide-oligonucleotide conjugates. The probes were prepared by incorporating suitable amino acid residues, such as lysines, in the polyamide, which were then used as sites for the attachment of the non-radioactive(More)
The difficulty of assessing nebulizer responses in chronic obstructive pulmonary disease (COPD) has been demonstrated before. This study aims to re-examine both the role of domiciliary nebulizers in COPD and also bronchodilator (BD) assessment in individuals. In a double-blind, randomized, cross-over trial, 19 stable patients with severe COPD were given the(More)
Eighty 4-month-old calves of both sexes and of two selected lines differing by 70 kg in their predicted total yield of milk fat and protein were injected intravenously with three of four GH secretagogues: these were, per kg liveweight; (i) 0.2 micrograms human GH-releasing factor (1-29) (GRF), (ii) 0.2 micrograms TRH, (iii) a combination of (i) and (ii),(More)
We have developed methods for the synthesis of peptide-oligodeoxyribonucleotide conjugate molecules in particular, and polyamide-oligonucleotide conjugates in general. Synthesis is carried out by a solid-phase procedure and involves the assembly of a polyamide on the solid support, conversion of the terminal amino group to a protected primary aliphatic(More)
The lymphocyte response to mitogens is frequently used as a screening method for monitoring general immunocompetence. In practice, however, the technique is potentially misleading. The results presented here suggest that temporal variation in lymphocyte response is the norm. Considerable variation in response to phytohemagglutinin was found for several dogs(More)
