Solar cells sensitized by donor-linked concerted companion dyes

Journal of Materials Chemistry C, 2023
Donor-linked concerted companion dyes have been synthesized for fabricating solar cells. The results indicate that a longer linking chain is favorable for improving the proportion of double anchoring, resulting in superior photovoltaic performance.

Cat Red Blood Cell Thiopurine S-Methyltransferase: Companion Animal Pharmacogenetics

The Journal of Pharmacology and Experimental Therapeutics, 2004
A common genetic polymorphism for thiopurine S-methyltransferase (TPMT) is a major factor responsible for individual variation in the toxicity and therapeutic efficacy of thiopurine drugs in humans. We set out to determine whether inheritance might also influence the level of TPMT activity in the domestic cat, Felis domesticus.

Plastids in sieve elements and companion cells of Tilia americana

Planta, 1971
Contrary to an earlier report, the sieve elements and companion cells of Tilia americana contain plastids. In young sieve elements and companion cells the plastids contain a moderately electronopaque matrix and internal membranes; the latter are very numerous in the plastids of the sieve elements.

Nanoparticles and cells: good companions and doomed partnerships

Organic & Biomolecular Chemistry, 2007
Engineered nanoparticles are emerging as useful tools for different purposes in life sciences, medicine and agriculture. Nanomedicine, an emerging discipline, involves the application of nanotechnology (usually regarded within the size range of 1-1000 nm) in the design of systems and devices that can facilitate our understanding of disease ...

Intercommunication between mammalian oocytes and companion somatic cells

BioEssays, 1991
AbstractCellular interactions in the mammalian ovarian follicle between its germ‐line and somatic cell components are crucial for its development and function. These interactions are mediated by both membrane gap junctions and paracrine factors. Somatic cell‐to‐oocyte communication is essential for oocyte growth and the regulation of meiotic maturation.

Companion Cells and Transfer Cells

1975
Phloem tissue as a whole, according to the introduction of this term by Nageli (1858), consists of sieve elements, sclerenchymatic elements and parenchymatic elements. Companion cells and transfer cells, the two cell types to be considered more in detail in the following, belong to the latter group.
