Robert Hooke, a scientist, was the first person in 1665 to discover the presence of cells, using a microscope. Anton van Leeuwenhoek first discovered free-living algae Spirogyra cells in water in the pond in 1674 with the improved microscope. The living cells were first discovered by Antony V...

Previously studies have indicated that the number of fish species as well as the total fish biomass in the Chishui River increased gradually along the upstream–downstream gradient, because of the increase in living space, habitat availability and food diversity (Wu et al. 2011a, 2011b). In ...
cells, within the closely opposing cells of a single tubule, within numerous cells of several closely opposed tubules, or generally throughout the tubules of the hepatopancreas. Often, epithelial cells containing virus-infected nuclei detached from the basement membrane of the tubule and were ...
1. All living organisms are made of one or more cells. 2. Cells are the basic units of structure and function. 3. Cells come only from pre-existing cells. CELL DIVERSITY Cell Shape –A cell’s shape reflects its function. Cell Size –Cell size is limited by a cell’s surface area–...
During the last ten years three oceanographic expeditions were conducted to search for the presence of living fauna in the sediments of the deep anoxic hypersaline L'Atalante basin (Mediterranean Sea). We report here that the sediments of the L'Atalante basin are inhabited by three species of th...
A total of 47 juvenile mussels were found in four of the 75 samples collected from the two study sites in Fildes Bay. Whereas mussels were observed at both sites, virtually all individuals (44) were collected in a single core dominated by the spongeKirkpatrickia variolosa(Kirkpatrick, 1907),...
We found that first investments were similar across groups, but feedback learning abilities were compromised in patients relative to HCs, but not different between patient groups. The novel, trial-by-trial, proportional assessment method revealed results that were similar to the method using ...
Regarding the cellular migration of HUVEC cells towards a wound (scratch assay), the native and PEG-CdtVEGF (5 nM) induced wound closure after 12 h of 49.5% and 35.8%, respectively (Figure 6B,C), demonstrating that the effects observed in the presence of both forms of CdtVEGF were ...
