The noncentrosomal cortical microtubules (CMTs) of land plants form highly ordered parallel arrays that mediate cell morphogenesis by orienting cellulose deposition. Since new CMTs initiate from dispersed cortical sites at random orientations, parallel array organization is hypothesized to require selective pruning of CMTs that are not in the dominant orientation. Severing of CMTs at crossover ...

BACKGROUND Hospital-acquired anemia (HAA) during acute myocardial infarction (AMI) is associated with higher mortality and worse health status and often develops in the absence of recognized bleeding. The extent to which diagnostic phlebotomy, a modifiable process of care, contributes to HAA is unknown. METHODS We studied 17,676 patients with AMI from 57 US hospitals included in a contemporar...

The aim of this study was to evaluate the effects of the headgear activator (HGA) and Herbst appliance during active treatment and retention and at follow-up in children with a skeletal Class II malocclusion. The two groups comprised 16 consecutive male patients (mean age 11.6 +/- 1.42 years) treated with a HGA and 16 male patients (mean age 12.6 +/- 1.13 years) treated with a Herbst appliance ...

We analize the properties of dense granular systems by assuming a hydrodynamical description , based on conservation laws for the particle number density and linear momentum. We combine analytical methods and experimental and numerical results obtained by ensemble-averaging of data on creep during compaction and molecular dynamics simulations of convective ow. 1 INTRODUCTION In spite of the ear...

OBJECTIVE Self-management of type 2 diabetes including avoidance of hypoglycemia is complex, but the impact of cognition on safe self-management is not well understood. This study aimed to assess the effect of baseline cognitive function and cognitive decline on subsequent risk of severe hypoglycemia and to assess the effect of different glycemic strategies on these relationships. RESEARCH DE...

Raw water from the Songhua River was treated by four types of coagulants, ferric chloride (FeCI3), aluminum sulfate (AI2(SO4)3), polyaluminum chloride (PACI) and composite polyaluminum (HPAC), in order to remove dissolved organic matter (DOM). Considering the disinfection byproduct (DBP) precursor treatability, DOM was divided into five chemical fractions based on resin adsorption. Trihalometha...

Abstract The Bohai Bay Basin in East Asia is a rift basin created by Cenozoic subduction of the oceanic Pacific plate beneath continent. Many prior studies suggest that was initially formed Paleocene with development several NNE-trending extensional grabens, but subsequently impacted right-lateral shear along these existing structures middle Eocene, transforming into transtensional and producin...

Aim. To develop the composition and laboratory technology of a therapeutic preventive mouthwash based on plant active ingredient study number its quality indicators. Materials methods. When developing drug, pharmaceutical ingredients (APIs) excipients approved for medical use widely used in practice were selected. The information-search, information-analytical, organoleptic, physicochemical, ph...
