Phototargeting oral black-pigmented bacteria.
We have found that broadband light (380 to 520 nm) rapidly and selectively kills oral black-pigmented bacteria (BPB) in pure cultures and in dental plaque samples obtained from human subjects with chronic periodontitis. We hypothesize that this killing effect is a result of light excitation of their endogenous porphyrins. Cultures of Prevotella intermedia and P. nigrescens were killed by 4.2 J/...
متن کاملThe Black Bug Myth: Selective photodestruction of pigmented pathogens.
BACKGROUND AND OBJECTIVE It is commonly believed that pigmented pathogens are selectively targeted by dental lasers. To test this notion optical diffuse reflection spectroscopy (DRS) was used to obtain absorption spectra for the periodontal pathogens, Porphyromonas gingivalis (Pg) and Prevotella intermedia (Pi). MATERIALS AND METHODS Spectra from 400 to 1,100 nm wavelengths of Pg colonies cul...
متن کاملInternet Appendix to ``Speculative Betas'' citecolor=black
A. Proof of Theorem 1 Proof. We solve the model here allowing for heteroskedastic dividends σ2 i . Theorem 1 can then be proved as the special case σ 2 = σ 2 i . We assume that assets are ranked in ascending order of β/σ2. We first posit an equilibrium structure. We then check ex-post that it is indeed an equilibrium and that it is a unique equilibrium. Let ī ∈ [2, N ] and let μi be the share h...

which can be shown to be equivalent to MMDH(q, p) 2 = Ex,x′∼p[k(x, x′)]− 2Ex∼p;y∼q[k(x, y)] + Ey,y′∼q[k(y, y′)]. We show that kernelized discrepancy is equivalent to MMDHp(q, p), equipped with the p-Steinalized kernel kp(x, x ′). Proposition 1.1. Assume (3) is true, we have S(q, p) = MMDHp(q, p). Proof. Simply note that Ex′∼p[kp(x, x′)] = 0 for any x, we have MMDHp(q, p) 2 = Ex,x′∼q[kp(x, x′)] ...
متن کاملDoes the Appendix Location Change During Pregnancy?
Background: Early diagnosis of appendicitis is important during pregnancy. Unlike omentom, cecum and appendix are not likely to be displaced by the growing uterus, so the concept of position change of the appendix during pregnancy is questionable. Objective: To determine the anatomical location of appendix during pregnancy. Methods: In a prospective study from October 1995 to March 1999, 291 w...
