A review of mentoring deaf and hard-of-hearing scholars.

Diversification of the scientific workforce usually focuses on recruitment and retention of women and underrepresented racial and ethnic minorities but often overlooks deaf and hard-of hearing (D/HH) persons. Usually classified as a disability group, such persons are often members of their own sociocultural linguistic minority and deserve unique support. For them, access to technical and social information is often hindered by communication- and/or language-centered barriers, but securing and using communication access services is just a start.

Fatty acids differentially modulate insulin-stimulated endothelial nitric oxide production by an Akt-independent pathway.

Background: Insulin increases endothelial nitric oxide (NO) production by activating endothelial nitric oxide synthase (eNOS) through protein kinase B (Akt)-mediated phosphorylation of serine residue 1179 (p-eNOS serine 1179). Because fatty acids modulate insulin-stimulated Akt signaling cascades in smooth muscle cells, we hypothesized that fatty acids would differentially regulate endothelial Akt signaling, eNOS phosphorylation, and NO production.

Methods: Porcine pulmonary artery endothelial cells (PAECs) were treated for 3 hours with 100 microM oleic (18:1) or eicosapentaenoic (20:5) acids or with an equivalent volume of ethanol vehicle (0.
