Analysis of ecdysteroids in different developmental stages of Hymenolepis diminuta

Molecular and Biochemical Parasitology, 1987
Prepatent and patent adult Hymenolepis diminuta from the intestines of rats, H. diminuta eggs recovered from the faeces of rats harbouring patent infections, and infective cysticercoids from the beetle intermediate host were analysed for free and conjugated ecdysteroids.

rDNA subtypes and their transcriptional expression in zebrafish at different developmental stages

Biochemical and Biophysical Research Communications, 2020
Eukaryotic 18S, 5.8S and 28S rRNAs are processed from a single transcript transcribed from the 45S rDNA gene, which is normally tandemly arrayed over hundred copies in a genome. Recently, a maternal (M) subtype and a somatic (S) subtype of rDNA were identified in zebrafish, with M-subtype on chromosome 4 and S-subtype on chromosome 5.

Characteristics of osteoclasts at different developmental stages and therapeutic strategies

European Journal of Medicinal Chemistry
Osteoclasts are defined by their unique capacity to regulate bone resorption, serving as the primary effector cells in skeletal degradation and remodeling cascades. However, multiple studies show that osteoclasts are involved not only in bone resorption but also in repair, tumor spread, and neurogenesis.

Glycosylation changes in different developmental stages of Trichinella

Biologia, 2009
The in situ identification of carbohydrate structures in Trichinella spiralis intestinal larvae, adults and L1 muscular larvae was carried out by lectin histochemistry, with emphasis on the O-linked glycans. The absence of reactivity with two lectins-TML and MAL indicated that Trichinella spiralis does not synthesize sialic acid.

Characteristics of nasal mucosal barrier in lambs at different developmental stages

Developmental & Comparative Immunology, 2023
The mucosal barriers of a lamb's nasal cavity are composed of a multi-layer barrier designed to protect against the invasion of harmful microorganisms. However, despite the protective measures, respiratory pathogens still infect the sheep from the nasal cavity. Therefore, our study aimed to investigate the characteristics of lamb's nasal cavity barrier

Uptake of Metronidazole in Artemia at Different Developmental Life Stages

Journal of Aquatic Animal Health, 2011
Abstract The purpose of this study was to examine the capacity of live brine shrimp Artemia spp. to accumulate metronidazole at different developmental life stages. Metronidazole is used in fish as an antiparasitic medication. An effective drug delivery method is to enrich the Artemia with metronidazole and offer them as live feed to the

Sensitivity of different generations and developmental stages in studies on reproductive toxicity

Toxicology Letters, 2014
Numerous studies on reproductive toxicity are expected to be necessary under the EU program on Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH). Therefore, it is important to analyse existing testing strategies including also the recently implemented extended one-generation reproduction toxicity study (EOGRTS, OECD guideline

Expressed sequence tags from persimmon at different developmental stages

Plant Cell Reports, 2008
Persimmon (Diospyros kaki Thunb.) is an important fruit in Asian countries, where it is eaten as a fresh fruit and is also used for many other purposes. To understand the molecular mechanism of fruit development and ripening in persimmon, we generated a total of 9,952 expressed sequence tags (ESTs) from randomly selected clones of two different cDNA ...

Anthraquinones in different developmental stages ofGaleruca tanaceti (Coleoptera, Chrysomelidae)

Journal of Chemical Ecology, 1991
The overwintering eggs and the larvae of the leaf beetleGaleruca tanaceti (L.) contain hydroxylated anthraquinones. In both developmental stages, l,8-dihydroxy-3-methylanthraquinone (= chrysophanol) and 1,8-di-hydroxyanthraquinone (= chrysazin) were detected by GC-MS and GC-FTIR analyses. In the eggs, chrysazin was found only in traces.

Identification of different radiolabelled antigens of the developmental stages of Onchocerca volvulus

Acta Tropica, 1990
By using radioiodination methods which are thought to label preferentially the surface followed by SDS-PAGE and autoradiography, components of different developmental stages of O. volvulus have been identified. Between 2 and 10 polypeptide antigens were revealed on infective larvae (L3), females, males, eggs, nodular and skin microfilariae by using ...
