CELL BIOLOGY: Bending Bugs

Sitting on the Fence: Biology, Feminism and Gender-bending Environments

Synopsis — In this article, I use the example of “gender-bending” chemicals to explore some of the ways we think about “nature.” Feminist biologists occupy a tricky position, having both to accept the reality of nature to some degree (especially if working in the lab, or when critiquing biological determinism); but we must also recognize the ways in which knowing about nature is socially constr...

Good Bugs Vs . Bad Bugs

Control of micro-organisms during completion of hydraulically fractured wells is a significant component in successful development of a production system. Detrimental bacteria—“bad bugs”—such as sulfate-reducing bacteria (SRB) introduced into the reservoir during drilling or completion, can facilitate biogenic sulfide production, resulting in souring of production fluids and gas, iron sulfide f...

A review of Biology and clinical use of Mesenchymal stem cell: an immune -modulator progenitor cell

Human mesenchymal stem cells (hMSCs), which also called mesenchymal stromal cells, are multipotent stem cell. Human MSCs typically are positive for the surface markers CD44, CD73, CD90, CD105, CD106, and also negative for hematopoietic markers CD34 and CD45.These cells can be isolated from postnatal bone marrow, adipose tissue, placenta, and scalp tissue, as well as from various fetal tissues. ...

Bugs versus bugs: probiotics, microbiome and allergy.

exposure to infections. Although exposure to infections may be one source of immune education, the most extensive interaction of the human body with microbes occurs within our own gut, which, in addition to being the site of greatest bacterial colonization, is also the largest lymphoid organ in the body. Over 40 years ago, it was reported that germ-free status resulted in spontaneous allergy an...
