Cellular structure and molecular functions of plants, animals, bacteria, and viruses [PDF]
Plant cells are the basic unit of life in organisms of the kingdom Plantae. These organisms as eukaryotic cells have a true nucleus along with particular structures called organelles that perform various functions.

Climate warming can directly affect biological processes in marine environments. Here, we investigated if warming (+2 °C) can change dynamics in viral and prokaryotic populations in the cold seasons in natural seawaters. We monitored the changes in viral

A novel prokaryotic promoter identified in the genome of some monopartite begomoviruses. [PDF]
Geminiviruses are known to exhibit both prokaryotic and eukaryotic features in their genomes, with the ability to express their genes and even replicate in bacterial cells.

Cell Biology of Prokaryotic Organelles [PDF]
Mounting evidence in recent years has challenged the dogma that prokaryotes are simple and undefined cells devoid of an organized subcellular architecture. In fact, proteins once thought to be the purely eukaryotic inventions, including relatives of actin and tubulin control prokaryotic cell shape, DNA segregation, and cytokinesis.

Optimization of Interleukin-5 Protein Expression in BL21 Strain of Escherichia Coli
Background: In asthma, the relationship between number of eosinophils and severity of this disease supports the hypothesis that eosinophil is the major effector cell in inflammation of airway. Evolution of eosinophils is regulated by interlukin-5 (IL-5).

Modeling the winter-to-summer transition of prokaryotic and viral abundance in the Arctic Ocean. [PDF]
One of the challenges in oceanography is to understand the influence of environmental factors on the abundances of prokaryotes and viruses. Generally, conventional statistical methods resolve trends well, but more complex relationships are difficult to ...

How Do Prokaryotic Cells Cycle? [PDF]
This issue of Current Biology features five reviews covering various key aspects of the eukaryotic cell cycle. The topics include initiation of chromosome replication, assembly of the mitotic spindle, cytokinesis, the regulation of cell-cycle progression, and cell-cycle modeling, focusing mainly on budding yeast, fission yeast and animal cell model ...

Infrared nanoscopy and tomography of intracellular structures
Kanevche and colleagues present a combined imaging method employing scattering-type scanning near-field optical microscopy and Fourier-transform infrared spectroscopy to visualize the internal structures of cells. Demonstrating their method on eukaryotic
