Polypyrrole-based sensor for hydrazine and ammonia (1990)
Journal Article

An ultra-thin layer of polypyrrole can be coated on non-conducting substrates, e.g., acrylic, by dip coating into a colloidal suspension of polypyrrole. This thin coating reversibly combines with low concentrations of ammonia or hydrazine with a conc... Read More about Polypyrrole-based sensor for hydrazine and ammonia.

Arterial pulse modulates steady-state ocular accommodation (1990)
Journal Article

Rapid and continuous fluctuations in ocular focus are known to occur when the eye views a stationary target. The advent of high-speed infra-red optometers has established that these microfluctuations of ocular accommodation have two dominant componen...

An immunological study of the secretory activity of neurons producing melanin-concentrating hormone in a teleost (1989)
Journal Article

The melanin-concentrating hormone is a general vertebrate neurosecretory peptide which, in bony fish, serves as a neurohypophysial hormone influencing pigmentary changes in response to background colour. Young carp were reared for six months in white... Read More about An immunological study of the secretory activity of neurons producing melanin-concentrating hormone in a teleost.

Immunocytochemical demonstration of melanin-concentrating hormone and proopiomelanocortin-like products in the brain of the trout and carp (1989)
Journal Article

Immunocytochemistry on frozen sections revealed that in both the trout and the carp, parvocellular neurones located in the medial basal hypothalamus (medial nucleus lateralis tuberis) were immunostained by antisera against three molecules known to be...

A promising material for non-linear optics: Observation of second harmonic generation from 4-[N-(4-carboxypentyl)-N-methylamino]-4′-nitrostilbene- coated substrates (1988)
Journal Article

Glass coated with a nitro amino stilbene carboxylic acid using the Langmuir-Blodgett technique gave a non-centrosymmetric material exhibiting second harmonic generation, 1.06 to 0.53 μm.

Localisation and identification of melanocyte-stimulating hormones in the fish brain (1988)
Journal Article

The existence of melanocyte-stimulating hormone (MSH) in fish brains was investigated by a range of techniques: radioimmunoassay, HPLC, bioassay, and immunocytochemistry. Immunoreactive αMSH (irαMSH) was detected by radioimmunoassay in all regions of... Read More about Localisation and identification of melanocyte-stimulating hormones in the fish brain.

Opioid binding sites in the fish brain: An autoradiographic study (1988)
Journal Article

Cryostat sections of trout brains were incubated with tritiated opioid ligands (5 nM [3H]etorphine or 4 nMd-[3H]Ala2, Met5 enkephalinamide) with the initial aim of locating opioid binding sites associated with the hypothalamo-pituitary axis. Naloxone... Read More about Opioid binding sites in the fish brain: An autoradiographic study.

IR studies of pyroelectric Langmuir-Blodgett films (1987)
Journal Article

Alternate-layer Langmuir-Blodgett (LB) assemblies, consisting of 22-tricosenoic acid with three different amine derivatives, have been fabricated. The pyroelectric activity in the films has been assessed and correlated with their structures determine... Read More about IR studies of pyroelectric Langmuir-Blodgett films.

Pyroelectric behaviour of Langmuir-Blodgett films containing polar chromophores (1987)
Journal Article

The pyroelectric behaviour of Langmuir-Blodgett films containing several different polar chromophores was studied. Two distinct levels of activity are seen. By comparison with films containing no chromophores it is shown that the lower level of activ... Read More about Pyroelectric behaviour of Langmuir-Blodgett films containing polar chromophores.

Hypothalamo-pituitary-interrenal responses to opioid substances in the trout. I. Effects of morphine on the release in vitro of corticotrophin-releasing activity from the hypothalamus and corticotrophin from the pituitary gland (1987)
Journal Article

The effects of morphine and naloxone on the secretion in vitro of corticotrophin (ACTH) and and corticotrophin-releasing factor (CRF) by the pars distalis and hypothalamus, respectively, have been studied in the trout. The spontaneous in vitro secret... Read More about Hypothalamo-pituitary-interrenal responses to opioid substances in the trout. I.
