TO THE EDITOR: Drs. Lepers and colleagues (1) have written an interesting commentary in response to our recently published paper (2) on aerobic power in octogenarian athletes and healthy untrained age-matched men. Our primary intent was to evaluate aerobic potential at the whole body and myocellular level to gain more insight into the health benefits of lifelong endurance exercise in individual...

TO THE EDITOR—We thank Thysen et al for their cautionary perspective on BCG vaccination policy changes. Although we found improved immunogenicity of BCG vaccine in human immunodeficiency virus (HIV)–exposed infants vaccinated at 8 weeks of age, compared with immu-nogenicity among those vaccinated at birth [1], we do not recommend changes to vaccine-delivery services on the basis of these data. ...

TO THE EDITOR—We read with interest the correspondence by Karagoz et al [1] regarding our article on the prevalence of Middle East respiratory syndrome coro-navirus (MERS-CoV) nasal carriage and compliance with the Saudi health recommendations among pilgrims attending the 2013 Hajj [2]. On behalf of all authors of our original article, we would like to respond to their correspondence. Karagoz e...

REPLY: We are grateful for the comments by Ahissar et al. on our recent manuscript (Masri et al. 2008) and for the opportunity to respond to these comments. Our manuscript focused on testing the hypothesis—formulated by Ahissar and collabo-rators—that the paralemniscal pathway in the rat's vibrissae system functions as a phase-locked loop (PLL) (Ahissar et al. 2000; Sosnik et al. 2001). We emph...

To the Editor: Thank you for your attention to our recent publication (1). As the primary focus of this manuscript was to improve understanding in how multiplex testing and Next-generation sequencing (NGS) technology are being integrated into clinical practice, details on our approach to specific variant classification are outside the scope of this report. However, the classification of DNA var...

Stimulated by our 2015 Current Biology paper [1], Zambon et al. reinvestigated how three myosin isoforms participate in the formation and constriction of the contractile ring in fission yeast. Our paper presented evidence that these myosin isoforms have distinct roles: "Conventional myosin-II Myo2 is crucial to ring assembly, unconventional myosin-II Myp2 is most important for ring constriction...
