Chongqing, China. In J Huazhong Univ Sci Technolog Med Sci, 28 Feb 2014
The examinations included questionnaire investigation, visual acuity test, naked-eye examination, measurement of peripheral anterior chamber depth (Van Herrick's technique), detection of intraocluar pressure (IOP) with a Perkins hand-held applanation tonometer (HA-2) and examination of the optic disc by using a 78 diopters (D) lens (including the cup-disc ratio, cup/disc ratio asymmetries, horizontal and vertical diameter, notching and optic disc hemorrhages).
New vaccines against influenza virus.
Atlanta, United States. In Clin Exp Vaccine Res, Jan 2014
The strategies of universal vaccines include the matrix 2 protein, the hemagglutinin HA2 stalk domain, and T cell-based multivalent antigens.

Fort Worth, United States. In Cell Transplant, 2009
Moreover, the use of the NH2-terminal domain of the influenza virus hemagglutinin-2 subunit (HA2) or photosensitive PTDs has been shown to specifically enhance macropinosome escape.
Atomic structure of the ectodomain from HIV-1 gp41.
Boston, United States. In Nature, 1997
These features, and the existence of a similar reversal of chain direction in the fusion pH-induced conformation of influenza virus HA2 and in the transmembrane subunit of Moloney murine leukaemia virus (Fig. 1a-d), suggest a common mechanism for initiating fusion.
