Abstract:

Rice blast caused by the ascomycete fungus Magnaporthe oryzea is one of the most widespread and destructive rice diseases worldwide. The most economical and effective strategy for controlling rice blast is the rational use and promotion of disease-resistant varieties. To enhance disease resistance, it is essential to analyze the resistance levels of rice varieties and the role of resistance (R) genes. To investigate blast resistance, R gene distribution, and their contributions in japonica rice, 287 varieties were evaluated through artificial inoculation. PCR detection was also performed using

Abstract:

HIGHLIGHTS The DIVA scoring tool has previously been validated in the pediatric ED setting. Our project applied DIVA to an inpatient pediatric sample. DIVA may not predict likelihood of PIV success in the inpatient setting. Background: First-attempt success rate for placing pediatric peripheral intravenous (PIV) catheters ranges from to 24% to 52%. Multiple attempts can increase risk of deleterious outcomes. It is essential to screen pediatric patients appropriately to identify those who will require additional resources for successful PIV placement. Methods: A convenience sample of hospitaliz

Abstract Introduction: Parainfluenza virus (PIV) often causes self-limiting upper respiratory tract infection (URTI) in the immunocompetent host, but can result in severe and even life-threatening lower respiratory tract infection (LRTI) in patients with hematologic malignancies or following stem cell transplantation. In contrast to respiratory syncytial virus or seasonal influenza, PIV is transmitted all year round. Here we analyze clinical characteristics of PIV infection in immunocompromised patients, assess possible risk factors for severe infection and report on nosocomial transmission as

Abstract:

Imidazolium salts with complex anions [Co₂Li₂(Piv)₈]²⁻ are formed as undesirable products of the reactions of heterometallic compound [Co₂Li₂(Piv)₆(Py)₂] with N-heterocyclic carbenes ItBu and IPr. The study of the magnetic properties of complex (HItBu)₂[Co₂Li₂(μ₂-Piv)₆(Ƙ¹-Piv)₂] shows that this compound is a single molecule magnet. Slow magnetic relaxation in the complex occurs due to a combination of the direct and Raman mechanisms.

ABSTRACT Piv, a unique prokaryotic site-specific DNA invertase, is related to transposases of the insertion elements from the IS110/IS492 family and shows no similarity to the site-specific recombinases of the tyrosine- or serine-recombinase families. Piv tertiary structure is predicted to include the RNase H-like fold that typically encompasses the catalytic site of the recombinases or nucleases of the retroviral integrase superfamily, including transposases and RuvC-like Holliday junction resolvases. Analogous to the DDE and DEDD catalytic motifs of transposases and RuvC, respectively, four

It is well known that the aneurysm is formed and ruptured at the site of high wall shear stress (WSS).

Pseudomonas aeruginosa is a leading cause of bacterial keratitis, especially in users of contact lenses. These infections are characterized by extensive degradation of the corneal tissue mediated by Pseudomonas protease activities, including both Pseudomonas protease IV (PIV) and the P. aeruginosa small protease (PASP). The virulence role of PIV was determined by the reduced virulence of a PIV-deficient mutant relative to its parent strain and the mutant after genetic complementation (rescue). Additionally, the non-ocular pathogen Pseudomonas putida acquired corneal virulence when it produced

AbstractThe fourth Painlevé equation PIV is known to have symmetry of the affine Weyl group of type with respect to the Bäcklund transformations. We introduce a new representation of PIV, called the symmetric form, by taking the three fundamental invariant divisors as the dependent variables. A complete description of the symmetry of PIV is given in terms of this representation. Through the symmetric form, it turns out that PIV is obtained as a similarity reduction of the 3-reduced modified KP hierarchy. It is proved in particular that the special polynomials for rational solutions PIV, called

Reaction of 2,2′-bipyridine (2,2′-bipy) or 1,10-phenantroline (phen) with [Mn(Piv)2(EtOH)]n led to the formation of binuclear complexes [Mn2(Piv)4L2] (L = 2,2′-bipy (1), phen (2); Piv− is the anion of pivalic acid). Oxidation of 1 or 2 by air oxygen resulted in the formation of tetranuclear MnII/III complexes [Mn4O2(Piv)6L2] (L = 2,2′-bipy (3), phen (4)). The hexanuclear complex [Mn6(OH)2(Piv)10(pym)4] (5) was formed in the reaction of [Mn(Piv)2(EtOH)]n with pyrimidine (pym), while oxidation of 5 produced the coordination polymer [Mn6O2(Piv)10(pym)2]n (6).

Abstract:

Cessation of blood flow during ischemia will decrease both distending and shear forces exerted on endothelium and may worsen ischemic lung injury by decreasing production of nitric oxide (NO), which influences vascular barrier function. We hypothesized that increased intravascular pressure (Piv) during ventilated ischemia might maintain NO production by increasing endothelial stretch or shear forces, thereby attenuating ischemic lung injury. Injury was assessed by measuring the filtration coefficient ( Kf) and the osmotic reflection coefficient for albumin (ςalb) after 3 h of ventilated (95% O
