Pathogenic strains of Vibrio cholerae are responsible for endemic and pandemic outbreaks of the disease cholera. The complete toxigenic mechanisms underlying virulence in Vibrio strains are poorly understood. The hypothesis of this work was that virulent versus non-virulent strains of V. cholerae harbor distinctive genomic elements that encode virulence. The purpose of this study was to elucida...

In this paper C denotes a category and o1, o2, o3 denote objects of C. Let C be a non empty category structure with units and let o be an object of C. Observe that 〈o, o〉 is non empty. The following propositions are true: (1) Let v be a morphism from o1 to o2, u be a morphism from o1 to o3, and f be a morphism from o2 to o3. If u = f · v and f −1 · f = id(o2) and 〈o1, o2〉 6= ∅ and 〈o2, o3〉 6= ∅...

Intertidal organisms may employ circatidal rhythms to track the tidal cycle, but tidal patterns may vary within a species range and necessitate adaptation to the local tides. Circatidal rhythms were examined in populations of the eastern Pacific fiddler crab Uca princeps (Smith) from four sites with differing tidal characteristics, La Paz (24 10¢N; 110 21¢W), San Blas (21 33¢N; 105 18¢W) and Ma...

Background Abnormalities in the neurophysiological oscillatory mechanisms generating dominant resting-state eyes closed electroencephalographic (rsEEG) rhythms portray Alzheimer’s disease (AD) continuum, from preclinical to dementia stage. Here, we tested whether these abnormalities may be reproducible by analyzing rsEEG signals acquired bipolar configuration with a montage consisting of only f...

We use the abbreviation x1:k for x1, . . . , xk, o1:k for o1, . . . ok, h1:k for h1, . . . , hk. The sequence of DDO times up to observation time tk is denoted τ (1, k) = {ti : hi = 1, i = 1, . . . , k}. Forward functions are defined as αtk(u) = P [o1:k, τ (1, k),h1:k, Xk = u] and backward functions as βtk(u) = P[ok+1:n, τ (k + 1, n),hk+1:n|Xk = u]. The forward function is initialized with αt1(...

The emergence and spread of Vibrio cholerae O1 El Tor variant strains causing severe diarrhea has been witnessed worldwide in recent years. In the state of Odisha, India, the spread of the V. cholerae O1 El Tor variant strains was studied during outbreaks in 2008 and 2009. Analysis of 194 V. cholerae O1 Ogawa strains revealed that V. cholerae O1 El Tor variant strains are spreading gradually th...

Vibrio cholerae are Gram-negative bacteria that are differentiated into O1/O139 and non-O1/non-O139 serogroups depending on their ability to agglutinate with specific antiserum. In contrast to non-O1/non-0139 Vibrio cholerae, which are more prone to invade the bloodstream, Vibrio cholerae O1 is rarely the cause of bacteremia. We report a case of O1 Vibrio cholera bacteremia and primary peritoni...

Electroencephalographic (EEG) coherence was assessed during a 4-s aiming period prior to trigger pull in expert marksmen (n = 10) and skilled shooters (n = 9) over the course of a regulation round of small-bore rifle shooting. Although both groups were highly experienced, the skilled group had lower ability. Given that specialization of cortical function occurs as domain-specific expertise incr...

BACKGROUND Human immunodeficiency virus (HIV)-infected individuals are at increased risk of herpes zoster (HZ), even in the antiretroviral therapy (ART) era. Because concerns exist about the use of live-attenuated vaccines in immunocompromised individuals, a subunit vaccine may be an appropriate alternative. METHODS This phase 1/2, randomized, placebo-controlled study evaluated the immunogeni...

In this section we show that our rules from Figure 2 are sound for MTAL0, assuming no type abstraction or type naming is present. We begin by stating some lemmas about MTAL0 (Figure 4). Lemma 2.1 (Preservation) If ` O1 link O2 ; O then ` O Lemma 2.2 (Associativity of link) If ` (O1 link O2) link O3 ; O then ` O1 link (O2 link O3) ; O. Lemma 2.3 (Commutativity of link) If ` O1 link O2 ; O then `...
