Weaning of mammalian progeny is associated with a change in body shape and physical characteristics. It programs growth, composition, the tempo physiological development maturation, as well litter size parity and, thereby, reproductive strategy.

Chromosomes isolated from mouse leukemia L1210 cells were taken up by mouse macrophages, HeLa cells, and rat embryo fibroblasts following simple exposure in vitro. The process, which resembles pinocytosis or phagocytosis, was traced by autoradiography of chromosomes prelabeled with thymidine-H(3), and by staining techniques and phase contrast microscopy. During the first six hours, the uptake o...

The mammalian protein siderocalin binds hydroxypyridinone complexes of trivalent rare-earth metals and f-elements through cation-π electrostatic interactions. It can also be fused with biological vectors for the targeted delivery imaging therapeutic radionuclides.

Sphingolipids (SLs) are essential structural components of mammalian cell membranes. Our group recently determined that the oral anaerobe Porphyromonas gingivalis delivers its SLs to host cells and ability P. synthesize limits elicited inflammatory response during cellular infection.

To explore the mechanism of microRNA-125a reversing resistance laryngeal cancer stem cells to cisplatin from mitochondrial autophagy. The human carcinoma cell line Hep-2 was purchased Shanghai Bioleaf Biotechnology Co., Ltd. expression messenger RNA in each group analyzed by reverse transcription-polymerase chain reaction. migration and invasion ability evaluated Transwell assay. Cell apoptosis...

The hypothesis of a connection between the onset (or intensification) Northern Hemisphere Glaciation, stepwise increase in African aridity (and climate variability), and an important mammalian (including hominin) species turnover is textbook example initiation scientific idea its propagation science. It is, however, also persistent popularity despite mounting evidence against it. A critical rev...

background: recently, the use of t7 rna polymerase instead of other viral and cellular promoters is increasing due to high efficacy of transcription in the cell cytoplasm by this polymerase. in order to translate the transcripts produced by t7 rna polymerase in mammalian cell lines, it is necessary to include internal ribosome entry site (ires) sequences. in addition, if sequence of poly a sign...

An increasing number of new subtypes avian influenza viruses (AIVs) are reported to be infecting humans, including H3N2, H5N1, H7N9, H10N8, and the recently emerged H3N8 virus in China 2022. However, genetic biological properties currently prevalent AIVs not yet fully understood. This study reports isolation a novel triple reassortment (GD-H3N8) from chicken flocks Guangdong province, China, Th...
