PHYSIOLOGICAL STUDIES USING TISSUE CULTURES OF PLATYCERIUM CORONARIUM (KOENIG) DESV
… dependent on the photosynthetic status of the tissue which, in turn, was dependent on the CO2 availability in the headspace of the cultures. Photosynthesis, nitrate uptake and nitrate assimilation are therefore closely linked phenomena governing growth and development of P. coronarium tissues …

Development and characterisation of air-liquid interface exposure systems for cell and tissue cultures
… how aerosolised substances impact respiratory tissues, cellular responses, toxicity, and overall health. Aerosols possess opposing qualities, serving both as hazards and therapeutic tools, which underscores the critical necessity for rigorous safety testing. This thesis describes the …

The microbiological causes of chronic osteomyelitis at the University Teaching Hospital,Lusaka
… study involving the collection of deep tissue cultures following sequestrectomy and subjecting them to microscopy, culture and sensitivity examination so as to determine the causative organisms and their antimicrobial sensitivity pattern. RESULTS: Staphylococcus aureus was the most …

Free radical mediated oxidative stress in plant cancers
… stress and antioxidant protection in plant tissue cultures undergoing various stages of ageing and neoplastic progression towards a cancerous state. Two experimental systems were investigated: (1) <i>Beta Vulgaris</i> cultures comprising two fully habituated (cancerous), lines, one partially …

Physiological and morphological variation within and between populations of Suillus granulatus, as determined by mycorrhizal synthesis experiments
… Suillus granulatus differ in host specificity. Tissue cultures of Suillus granulatus used were from Nepal, (associated with Pinus wallichiana), Korea (Pinus densiflora) and the U.S. (Pinus strobus). Mycorrhizal effectiveness was used to measure host specificity. Useful characters for measuring …

Synthesis of labelled precursors of podophyllotoxin
… labelled precursors into intact plants and tissue cultures can give a much improved insight into the lignan biogenesis. The first part of the work has been to the synthesis of two diastereotopically labelled with ²H at C-4. Desoxypodophyllotoxin is the penultimate intermediate of the …

Developing a Functional in Vitro Model of the Neuromuscular Interface
… long-term, functionally contractile muscle tissue while providing compartmentalization and clear optical access for live imaging of muscle and motor neuron co-cultures. This work therefore presents STAMP, a microgroove patterning method for creating aligned, more physiologically relevant, …

Use of an Atg16l1 mouse model to study the role played by autophagy in neuroprotection
… central nervous system and in various other tissues. While polyubiquitinated aggregates are commonly associated with human neurodegenerative diseases, cell damage or accumulation of pathogenic proteins was not observed. To investigate autophagy in the context of virus‐host interaction, …

Development of simple 3D-printed scaffolds for liver tissue engineering
… liver transplants is to grow implantable liver tissue in the lab. A tissue-engineered liver for transplantation will require complex structures to support cell differentiation and integration with surrounding vasculature. Recent developments in 3D-printing (3DP™) technology allow the …

Estudo citoquímico de enzimas mitocondriais de Trypanosoma cruzi em culturas de tecido
… rnitochondrial enzymes in Trypanosoma cruzi in tissue cultures a cytochemical study at light and electron rnicroscopic levels was performed using chick embryo heart rnuscle cultures infected by the Y strain of the parasite. Tetrazolium salts were used as hidrogen aceptors of the reaction to …

Studying the biology of, and developing countermeasures to, a tick-transmitted hemorrhagic fever virus
… drive strong expression of CCHFV-GP in tissue cultures, with the replication competent vector possessing CCHFV-GP on the virion surface of rVSV. This permitted studies for the biology of the CCHFV-GPC and the application to a serological detection and characterization means for CCHFV …

Evaluation of fertile lines derived from the hybridization of Glycine max and G. tomentella
… the use of colchicine, hormone treatments, and tissue cultures. After two to five backcrosses with the cultivar Dwight, we obtained genetically stable lines with 2n=40 and 2n=42. Phenotypic evaluation of plant height, maturity, and seed protein and oil concentration, confirm introgression of G. …

Metabolic, biochemical and molecular profiling of Catharanthus roseus flower cultivars and transformed hairy roots for monoterpenoid indole alkaloid accumulation /
… procedure. Alternatively, CatharanthllS tissue cultures have been investigated as a source of these agents; however they do not produce vindoline, which is an obligate precursor to vinblastine and vincristine. The interest in developing high MIA cultivars of Catharantlws rosellS has …

Free radical mediated mechanisms in stress and development in in vitro crop plant systems
… the involvement of oxidative stress in plant tissue cultures. <i>Daucus carota</i> was used as a model system for the study of somatic embryogenesis and for the development of an enzyme linked immunosorbant assay (ELISA) technique, for the detection of hydroxynonenal-protein adducts in plant …

PROPAGATION OF PLANTS BY SOMATIC EMBRYOGENESIS
… the induction of somatic embryos in tissue cultures of four very different important crop species (coffee, kiwi-fruit, banana and pineapple). Large numbers of embryos of coffee were produced; alterations in the pattern of this regeneration under different cultural conditions were …

Isolation of novel antibiotic producing microorganisms from invertebrates
… by HPLC. As facilities for large scale liquid cultures were not available large scale preparation was performed from agar medium and the active fractions. HPLC showed that the extracts were complex and contained more than one active component. The purified fractions were chemically …
