We rated some reproductive characteristics of white shrimp Litopenaeus vannamei (Boone, 1931) males using 46 farmed individuals (weighing 21.42 +/- 0.56 g) and 40 wild individuals (weighing 36.10 +/- 0.72 g). In farmed shrimps, spermatophore mean weight was 8.94 +/- 0.51 mg; total mean sperm count was 3.90 +/- 0.27 x 10(6) in each spermatophore; and mean percentage of normal sperm was 86.9 +/- ...

OBJECTIVE To describe the time course of α4-integrin receptor desaturation and disease activity return in patients with relapsing-remitting MS who discontinued natalizumab and to investigate baseline and on-study predictors for the recurrence of disease activity. METHODS In the course of TOFINGO, a 32-week, patient- and rater-blinded multicenter, parallel-group study, we performed MRI, counte...

We calculate the contributions Ji Iwo) and J2(2wo) to the NMR relaxation rate Tp~(wo) caused by the motion of proposed molecular defects in polymer liquid crystals. The results are Ji c~ w(/~ and J2 oc wj~/~ for low Lamor frequencies wo. The scaring of the J functions with chain length is also given. It is hoped that NMR may offer a way of deterrn%ing the contribution of molecular defects to dy...

AIM To evaluate the effect of coronal flaring on the amount of debris extruded apically during root canal preparation using the Reciproc, WaveOne (WO) and OneShape (OS) single-file systems. METHODOLOGY Ninety extracted single-rooted mandibular incisor teeth were randomly assigned to six groups (n = 15 for each group) for canal instrumentation. Endodontic access cavities were prepared in each ...

Iron tris(2-methylpyridyl)amine (TPA) and iron 1-(bis(2-methylpyridyl)amino)-2-methyl-2-propanoate (BPyA) salts are characterized as water oxidation catalysts (WOCs) using sodium periodate. Under the conditions used, these complexes serve as homogeneous WOCs as demonstrated via kinetic analysis and dynamic light scattering (DLS). The Fe(BPyA) salt serves as both a mononuclear and dinuclear cata...

The title compound sodium dysprosium(III) bis-[tungs-tate(VI)], NaDy(WO(4))(2), has been synthesized under high temperature solution growth (HTSG) conditions in air. The compound crystallizes with the scheelite structure and is composed of isolated WO(4) tetra-hedra ( symmetry) with one set of bond lengths and distorted [(Na/Dy)O(8)] dodeca-hedra ( symmetry; occupancy ratio Na:Dy = 1:1) with tw...
