Osteomyelitis of the frontal bone

Osteomyelitis of the skull is a rare clinical presentation. It usually occurs as a complication of trauma or sinusitis. Its complications can be lifethreatening though the initial symptoms and signs are subtle. Early diagnosis and appropriate management to prevent CNS complications reduce morbidity and mortality significantly. Intracranial complications of sinusitis, focal infections and meningitis remain a great challenge. Mortality from complications is 20-40%. The prevalence of skull osteomyelitis is about 1.5% of all osteomyelitis

(3,5-Dimethyl­pyrazol-1-yl)[5-(3,5-dimethyl­pyrazol-1-ylcarbon­yl)-2-thien­yl]methanone

The title compound, C16H16N4O2S, crystallizes with two symmetry-independent half-mol­ecules in the asymmetric unit. All non-H atoms in each molecule lie in a crystallographic mirror plane. The mol­ecules form sheets in the ac plane, which then form stacks along the b axis. The sheets are connected via π–π stacking inter­actions [centroid–centroid distance between pyrazolato rings = 3.6949 (8) Å]

Effect of NPK (23-10-5) on Nodulation in Two Cowpea Varieties (Asontem and Asetenapa)

Effect of NPK fertilizer on nodulation at flowering / podding and at harvesting, was investigated in two early maturing cowpea varieties (Asontem and Asetenapa) in the major cropping seasons (March to August) of 2009 and 2013. In Trial 1 (2009), three levels of NPK fertilizer, comprising (i) no fertilizer, (ii) starter fertilizer only, using 23-10-05 at 125 kg/ha applied 9 days after sowing, and (iii) starter fertilizer plus a top-dress of 50 kg/ha sulphate of ammonia 21 days after sowing were tested in  . 2 x 3 factorial in a randomized complete block design with four replications. In Trial 2, a blanket dressing of 40 kg/ha triple super phosphate was combined with four rates of 23-10-05 NPK at 0, 30, 60 and 120 kg/ha, in a 2x4 factorial randomized complete block design with eight replications. In Trial 1, total nodule count per plant was higher than active nodules (p<0.05) at early flowering (12.66 & 2.24, respectively) and at harvest  (10.49 & 0.23, respectively) in both varieties. However, in Trial 2, total and active nodules were not significantly different at the same stage of development: 6.1 & 5.9, respectively, at podding and 2.3 & 1.9, respectively,  at harvest. In the two trials, variety and fertilizer significantly affected nodulation but the trends were not consistent. In Trial 1, neither fertilizer nor variety was significant in total or active nodule count at early flowering or at harvest (p>0.05). On the other hand, in Trial 2, Asontem bore significantly more nodules at podding (8.4 per plant) than Asetenapa (3.7 per plant), though fertilizer was not significant. By harvesting time, the total number of nodules per plant had reduced to a mean of 2.2. In this, Asontem had 2.5 at harvesting, while Asetenapa had 1.9 nodules per plant.

Review of empirical and emerging breeding methods and tools for yam (Dioscorea spp.) improvement: status and prospects

Open Access Article; Published online: 05 Dec 2019Yam (Dioscorea spp.) is an important tuber crop with tremendous potential as a functional food in the tropics and subtropics. However, the crop has not shown progressive productivity gain over decades due to various production constraints. This paper reviews the progress achieved in empirical breeding endeavours and the development, status and application of emerging breeding tools and technologies to translate genetic gains in yam improvement. Significant progress has been made in yam genetic improvement over the years which has led to the identification and development of several improved clones and sources of variability for various economically important traits. Substantial efforts have also been made to develop diverse molecular markers, transcriptome and metabolome profiles of crucial traits, trait mapping and generate reference genome sequences of the key species. However, there seems to be a slow translation of research improvements into widespread applications. These advances and the integration of empirical and emerging methods and technologies into the breeding process will enhance yam breeding efforts and ensure the quick delivery of improved varieties that possess superior agronomic and quality traits

{Bis[2-(3,5-dimethyl­pyrazol-1-yl-κN 2)eth­yl]amine-κN}chloridopalladium(II) chloride 0.25-hydrate

The title compound, [PdCl(C14H23N5)]Cl·0.25H2O, is a pseudopolymorph of the previously reported compound [PdCl(C14H23N5)]Cl·2H2O [de Mendoza et al. (2006 ▶). Acta Cryst. E62, m2934–m2936]. The cationic complex and chloride anion are disordered over two positions each in a 0.584 (4):0.416 (4) ratio. The geometry about the Pd atom is distorted square-planar. The pyrazole rings are almost perpendicular, forming a dihedral angle of 86.6 (6)° to each other, to mitigate steric conflict between their methyl groups
