Self-proclaimed female physician Ann Trow was a women?s reproductive health specialist as well as an abortion [3] provider in New York City, New York during the mid 1800s. Although she had no formal medical training or background, Trow provided women with healthcare and abortions under the alias Madame Restell. Restell gained attention across the United States for her career as a professional a...
Setaria Beauvois, 1812 is a genus of economically important forage species, including Setaria italica (Linnaeus, 1753) Beauvois, 1812 and Setaria viridis (Linnaeus, 1753) Beauvois, 1812, closely related species and considered as model systems for studies of C4 plants. However, complications and uncertainties related to taxonomy of other species of the genus are frequent due to the existence of ...
With the use of neuraminidase (NA) inhibitors (BCX-1812, oseltamivir, or zanamivir), drug-resistant variants of influenza A viruses were generated that lacked characteristic markers of resistance, such as substitutions in the NA active center or in the hemagglutinin. Drug resistance was associated with the accumulation of defective (Delta) RNA segments encoding NA. This phenomenon could be expl...
We present the identification of the optical counterparts to the low-mass X-ray binaries 1A 1246−588 and 4U 1812−12. We determine the X-ray position of 1A 1246−588 from ROSAT /PSPC observations and find within the error circle a blue star with V = 19.45, B − V = 0.22 and R − I = 0.22 which we identify as the counterpart. Within the Chandra error circle of 4U 1812−12, a single star is present wh...
There exists a group of persistently faint galactic X-ray sources that, based on their location in the galaxy, high Lx/Lopt, association with X-ray bursts, and absence of low frequency Xray pulsations, are thought to be low-mass X-ray binaries (LMXBs). We present results from Chandra observations for eight of these systems: 4U 1708–408, 2S 1711–339, KS 1739–304, SLX 1735–269, GRS 1736–297, SLX ...
