(10) The body wall muscle and the blood vessel muscle are compared with other muscle types described in invertebrates.
(11) Although neither protein bound to heparin, gelatin, hexosamine, or uronic acid-Sepharose resins, their affinity for an invertebrate proteoglycan, their roles in sponge cell adhesion, and their peripheral membrane protein natures suggest that they may represent early invertebrate analogs of cell-associated vertebrate extracellular matrix adhesion proteins, such as fibronectin or vitronectin, or else an entirely novel set of cell adhesion molecules.
(12) In organisms as diverse as bacteria, plants, invertebrates, and vertebrates, synthesis of these proteins is directly correlated with the acquisition of thermotolerance.
(13) Invertebrate systems have proved to be quite useful for the development of an understanding of some processes in the central nervous system (CNS).

(17) To test the hypothesis that inositol trisphosphate (InsP3) mediates adaptation and excitation in invertebrate photoreceptors, we measured its formation on a rapid time scale in squid retinas.
(18) The cellular and circuit properties of individual identified neurons in invertebrates can be readily studied; hence it is possible to determine how the complex properties of nerve cells function in the generation of behavior.
(19) These processes may be conserved in a wide range of invertebrates and vertebrates.
(20) The action of ocular screening pigments of vertebrates (melanins) as well as those of invertebrates (ommochromes) on lipid peroxidation has been studied.
Keratose
Definition:
(n.) A tough, horny animal substance entering into the composition of the skeleton of sponges, and other invertebrates; -- called also keratode.
(a.) Containing hornlike fibers or fibers of keratose; belonging to the Keratosa.
Example Sentences:
(1) In a double-blind, randomized, within-patient comparative study, the efficacy and tolerability of Ro 14-9706 (an arotinoid methyl sulfone) in the treatment of actinic keratoses was compared with that of tretinoin (all-trans-retinoic acid).
(2) Two hundred and twenty-four people (36.4%) had a spontaneous remission of at least one of their solar keratoses.
(3) Liquid nitrogen spray followed by light electrodesiccation treatment is helpful in the management of flat warts, small skin tags, seborrheic keratoses, and cherry angiomas.
(4) Four patients are described who experienced an acute episode of eczematous dermatitis of the scrotum where 5-fluorouracil (Efudex) cream had inadvertently been applied in the course of treating warts and keratoses.
(5) A 70-year-old Japanese female with lepromatous leprosy developed squamous-cell carcinoma within a long standing area showing solar keratoses on her head.
(6) Lichen spinulosus is a benign follicular eruption seen primarily in younger persons and is frequently classified among the follicular keratoses.
(7) The proportion of the more common pathological diagnoses was unchanged between the two periods, but the proportion of correctly diagnosed naevi, cysts, and seborrhoeic keratoses increased in the second.
(8) This report documents the development of multiple cutaneous tumors, including squamous cell carcinoma, basal cell carcinoma, actinic keratoses, keratoacanthomas, and one case of lentigo maligna, in seven patients who received topical therapies for mycosis fungoides.
(9) HPV-41 was originally isolated from a facial wart, but its DNA has subsequently been detected in some skin carcinomas and premalignant keratoses (Grimmel et al., Int.
(10) Severe photoaging of the skin, which may be caused by exposure to both natural and artificial ultraviolet light, ultimately results in actinic keratoses and cancer.
(11) Comparison with other drugs and diseases suggests malignant keratoses are initiated in two stages by the cytotoxic effect of azathioprine, the role of immunosuppression remaining unproved.
(12) A 76-year-old woman with ovarian adenocarcinoma and sudden onset of many seborrheic keratoses is reported.
