The ultrathin structure of amoeboid flagellate Thaumatomastix sp. is considered. The cell is surrounded by two-layered triangular scales. They are formed on the surface of mitochondria. Pseudopodia grabbing bacteria run from ventricular furrow, which is armored with two longitudinal bands of ...
Further development is associated with a lengthening of the newly formed rudiment, nucleus, and flagella. The posterior end of the microgamete is attached to the cytoplasm of the gametocyte, and finally the entire microgamete buds off from the surface of the gametocyte. A mature microgamete,...
In future studies, we envision that by changing the molecular weight of the PEG or by changing the structure of the PEG chain to obtain a defect-free surface of the PEG brushes, a complete anti-biofouling effect can be achieved.Data availability No datasets were generated or analysed during ...
High-throughput, sensitive UPLC combined with our automated software for chromatographic analysis will accelerate the discovery of peptidoglycan composition and the molecular mechanisms of cell wall structure determination. 展开 关键词: cell wall, cytoskeleton, high-performance liquid chromatography (HPLC), ...
d Growth dynamics of Bdellovibrio species. Flagellated Bdellovibrio penetrates the outer membrane of Gram-negative bacteria into the periplasmic space (losing its flagella in the process), grows and elongates without cell division, resulting in a helical filament with multiple copies of the genome. As...
P. aeruginosa can colonize in airway epithelium with its surface appendages such as flagella and pili. And it produces toxins such as type III secretion protein, pyocyanin and LPS, and rapidly causes serious lung inflammation. A comprehensive reaction of immune cells such as macrophages, neutrophils...
An ultrathin dual-band planar chiral metamaterial (CMM) with giant optical activity using Fermat’s Spiral structure (FSs) was proposed, which could yield ... J Zhao,Y Cheng - 《Applied Physics B Lasers & Optics》 被引量: 1发表: 2018年 Challenges, recent advances and improvements for enhan...
A very short transitional helix (perhaps two rings) is present in the flagellar transition region, together with a short one-piece stellate structure. Numbering of individual flagella in different species of Pyramimonas has shown a surprising variation in the orientation of the flagellar apparatus ...
Nuclear pores were seen at all stages of development, but w... BV Deurs 被引量: 14发表: 1975年 EXCEPTIONS TO THE PREVAILING PATTERN OF TUBULES (9 + 9 + 2) IN THE SPERM FLAGELLA OF CERTAIN INSECT SPECIES Various deviations from classical 9 + 2 flagellar structure are found in sperm ...
Calcium bound calaxins inhibit activity of dynein motors within axoneme of the cell and result in high-amplitude asymmetric bending of flagella [19]. Exposure to high levels of cadmium [20] and lead [21] is reported to increase reactive oxygen species (ROS) production in testes and decrease...
