The blood is a connective tissue which flows all the parts of the human body. It is important for the circulation of gases, nutrients, and other necessary components. The blood is viscous than water. Blood is slightly basic, with a normal pH range of about 7.35- 7.45....
Describe the physical characteristics and function of blood. Describe the structure and functions of stems. Describe the composition, function and physical characteristics of whole blood and explain why it is classified as a connective tissue.
Fermentation of grain fiber takes place throughout the large intestine affecting beneficially the composition of gut microbiota, hence decreasing the permeability of gut barrier. Improved gut barrier function reduces leaking of endotoxic bacterial lipopolysaccharides (LPS) into the circulation. Lower ...

Leakiness of blood vessels in tumors may contribute to disease progression and is key to certain forms of cancer therapy, but the structural basis of the leakiness is unclear. We sought to determine whether endothelial gaps or transcellular holes, similar to those found in leaky vessels in ...
In this article, we review the similarities and differences between ginseng and notoginseng in terms of their chemical composition and pharmacological effects. Their chemical comparisons indicate that ginseng contains more polysaccharides and amino acids, while notoginseng has more saponins, volatile oil, ...
The mechanism of human immunodeficiency virus 1 (HIV-1) nuclear entry, required for productive infection, is not fully understood. Here, we report that in HeLa cells and activated CD4+ T cells infected with HIV-1 pseudotyped with VSV-G and native Env pro
When running a sequential mediation analysis to assess the path-specific effect not mediated by leukocyte composition in blood, the indirect effect through leukocyte composition in blood was − 2.4% in YFS and -0.8% in SKIPOGH, while it increased to 18.0% in YFS and 11.6% in SKIPOGH when...
We hypothesized that immune residency in the nasal mucosa of healthy individuals may differ across the age range. We applied single-cell RNA-sequencing and measured the cellular composition and transcriptional profile of the nasal mucosa in 35 SARS-CoV-2 negative children and adults, ranging in ...
