Post-synaptic specialization is critical to the neurotransmitter release and action potential conduction. The neuromuscular junctions (NMJs) are the synapses between the motor neurons and muscle cells and have a more specialized post-synaptic membrane th

Bifidobacteria, which commonly inhabit the primate gut, are beneficial contributors to host wellbeing. Anatomical differences and natural habitat allow an arrangement of primates into two main parvorders; New World monkeys (NWM) and Old World monkeys (OWM). The number of newly described bifidobacter...
1 Molecular characterization and mapping of the two alveolar capillary cell types. a, Feature plots showing log-transformed expression of marker genes used to annotate five molecularly distinct clusters (see t-SNE plot in Fig. 1b) derived by unsupervised clustering of lung endothelial cells in the...
The first, and simplest, arises when the whole body is in movement; the second, and more specific, occurs during movements of the jaw. What is more, the roles of two simple reflexes that I will discuss, the myotatic or stretch reflex of the jaw-closing muscles and the jaw-opening ...
of events that leads to the disassembly of synaptic sites during the synapse elimination process, we surveyed the distribution of molecular elements of the postsynaptic specialization, the basal lamina, and supporting Schwann cells during the process of synapse elimination that occurs after reinnervation....
aralocaspica occurs through carbon acquired by C[sub 4] photosynthesis. The development of this unique single-cell C[sub 4] system in chlorenchyma cells was studied by analysis of young (0.2-0.3 cm length), intermediate (ca. 0.5-0.6 cm length), and mature leaves (ca. 3 cm length). ...
compounds soluble in organic solvents entered the cells more rapidly than compounds soluble in water. These differences were attributed to the “selective solubility” of the membrane, that is, lipid-soluble materials would pass into the cell by dissolving in the corresponding lipid elements...
Amplification of endogenous silencing signals occurs by distinct secondary small interfering RNA (siRNA)-biogenesis mechanisms that involve RNA-dependent RNA polymerases in various lineages. Plant genomes can spawn new microRNA (miRNA)-generating loci de novo by inverted duplication of protein-coding seque...
region in that report. Therefore, we decided to repeat these observations and confirm how early the first molting occurs in the FFF region in the chicken. In contrast to the morphology of natal down feathers on the abdominal surface at one day post hatching (dph) (Fig.1b), feathers in ...
