Background: Facial pigmentation includes various entities such as melasma, lichen planus pigmentosus (LPP), and pigmented contact dermatitis. The pathogenesis may involve certain allergens, which be responsible for causing a disturbance in the dermoepidermal junction. elimination of inciting allergens aid successful treatment these patients. Objective: aim was to detect with patch photopatch te...

In general, lodging has been controlled by restricting nitrogen fertilizer application and/or using short cultivars. Growth retardants can also be used to solve this problem.The objective of this study was to evaluate the effect of rates and application times of three growth retardants on Pioneiro wheat cultivar. The trial was carried out in Viçosa-MG, from May to September 2005, in a factorial...

The cycloaddition of a diazoacetamide with ethyl 4,4,4-trifluorocrotonate proceeds with k = 0.1 M-1s-1. This second-order rate constant rivals those of optimized strain-promoted azide- alkyne cycloadditions, even though the reaction does not release strain. The regioselectivity and a computational distortion/interaction analysis of the reaction energetics are consistent with the formation of an...

OBJECTIVE To test whether well-child care visit anticipatory guidance can safely reduce emergency department (ED) visits. DESIGN Retrospective analysis comparing an intervention site with control sites using a "difference-in-differences" regression model. SETTING Primary care practices at the Mayo Clinic. PARTICIPANTS Children who attended a 15-month well-child care visit. INTERVENTIONS...

Three topical anesthetic agents namely Eutectic mixture of Local anesthetic 5% cream, Produit Dentaire ( 20% benzocaine) and Lignocaine 15% spray used in pediatric patients during various dental procedures requiring local anesthesia administration were evaluated in terms of onset of action and clinical efficacy for pain perception. In this study 210 patients aged between 6-14 years were randoml...

In the title compound, C(14)H(30)N(2) (2+)·2Cl(-), the N,N'-dicyclo-hexyl-ethyl-enediammonium cation posseses crystallographic symmetry, and thus the compound crystallizes with two formula units per unit cell. In the crystal, the cations and anions are linked by N-H⋯Cl hydrogen bonds, giving a two-dimensional network with {6,3} topology.

The experimental measurement and modeling of liquid chemical agent spread and sorption on a porous substrate are described. Experimental results with the nerve agent O-ethyl S-(2-diisopropylaminoethyl) methylphosphonothiolate (VX) demonstrate that the wetted imprint volume increases, even after the sessile drop volume is exhausted. This indicates the wetted imprint is only partially saturated, ...

The asymmetric unit of the title compound, C(17)H(13)N(3), contains two independent mol-ecules, which are non-planar as they are buckled owing to the ethyl-ene portion. The dihedral angle between the benzene rings is 26.4 (1)° in one mol-ecule and 32.9 (1)° in the other. In the crystal, the mol-ecules are disposed about a false inversion center, and are linked by two N-H⋯N hydrogen bonds, gener...
