The leaching behavior of five additives, including citric acid (CA), wood vinegar (WV), 1-hydroxyethylidene-1,1-diphosphonic acid (HEDP), polyaspartic acid (PASP) and FeCl3, was investigated to evaluate the possibility of enhanced phytoextraction of Pennisetum sp. from cadmium-contaminated soil. FeCl3 and CA have the highest leaching potential due to the ability that could convert large amounts of mobile fractions of Cd. The pot experiment showed that HEDP, WV, and PASP treatments could not only significantly increase the biomass of Pennisetum sp., but also maintain high uptake capacity of Cd by activating the stable fractions. HEDP has the highest Cd extraction efficiency and metal extraction ratio (MER) value. The phytoremediation efficiency could be improved mainly by increasing the biomass of the tolerant shoots, and Pennisetum sp. seems to have the maximum potential of phytoextraction to Cd with HEDP which could achieve a higher phytoextraction effect than Cd-hyperaccumulator.BACKGROUND For costal cartilage-based rhinoplasty, a method that could properly manage warping of the columellar strut graft and facilitate establishing a stable cartilaginous framework remains desirable. In this study, the authors present a new graft design named bilateral septal extension strut. It utilizes a pair of cartilage grafts with the shape of a fan, which are bilaterally fixated to the septum. Such "sandwiched" structure undertakes the combined functional roles of a columellar strut and a septal extension graft. METHODS Fifty-two female patients, ranging in age from 18 to 37 years, received augmentation rhinoplasty surgery based on the bilateral septal extension strut. Among these patients, 20 of them were primary cases, 26 secondary, and other six cases were tertiary. RESULTS Patients' own evaluations on the overall improvements in the nose rendered high satisfaction rate. There was no case of graft extrusion or infections. During the long-term follow-up, one case presented dorsal onlay graft warping and two cases presented in significant asymmetrical nostrils due to the deviation of the columellar at 12 months postoperatively and were corrected in the revision surgery. CONCLUSIONS The application of the bilateral septal extension struts can help mitigate the negative impact of strut graft warping, making it more manageable. As a result, reliable as well as sustainable support for both tip and lower lateral cartilages can be achieved in the long term.

Inositol pyrophosphates are necessary for these cellular responses. Inositol pyrophosphates are molecules composed of the phosphorylated myo-inositol ring that carries one or more diphosphates. Mutations in the enzymes that metabolize these molecules lead to altered patterns of stress resistance, altered morphology, and defective sporulation. Mechanisms to alter the synthesis of inositol pyrophosphates have been recently described, including inhibition of enzyme activity by oxidation and by phosphorylation. Cells with increased levels of 5-diphosphoinositol pentakisphosphate have increased nuclear localization of Msn2 and Gln3. The altered localization of these factors is consistent with the partially induced environmental stress response and increased expression of genes under the control of Msn2/4 and Gln3. Other transcription factors may also exhibit increased nuclear localization based on increased expression of their target genes. These transcription factors are each regulated by TORC1, suggesting that TORC1 may be inhibited by inositol pyrophosphates. Inositol pyrophosphates affect stress responses in other fungi (Aspergillus nidulans, Ustilago maydis, Schizosaccharomyces pombe, and Cryptococcus neoformans), in human and mouse, and in plants, suggesting common mechanisms and possible novel drug development targets.Cortical facilitation assessed with triad conditioning transcranial magnetic stimulation has been termed triad-conditioned facilitation (TCF). TCF has been supposed to reflect increased intracortical facilitation (ICF) at short interstimulus intervals (ISI) around 10 ms and an intrinsic rhythm of the motor cortex at longer ISI around 25 ms. To gain further insight into the pathophysiological mechanism of TCF, we systematically studied the effect of suprathreshold conditioning stimulus (CS) and test stimulus (TS) intensity on TCF. Various CS intensities and TS intensities were used in a triad-conditioning paradigm that was applied to 11 healthy subjects. ISI between pulses were studied between 5 and 200 ms. TCF at 10 ms ISI enhanced with increasing CS intensity but decreased with increasing TS intensity. The duration of facilitation was longer with higher CS intensity. However, TCF at 25 ms ISI could not be elicited with none of the CS and TS intensities addressed here. Our results are consistent with the notion of TCF at short ISI reflecting ICF. The enhanced and prolonged facilitation with increase of CS without additional isolated facilitation at longer ISI suggest a prolongation of ICF.Somatosensory afferent transmission strength is controlled by several presynaptic mechanisms that reduce transmitter release at the spinal cord level. We focused this investigation on the role of α-adrenoceptors in modulating sensory transmission in low-threshold myelinated afferents and in pathways mediating primary afferent depolarization (PAD) of neonatal mouse spinal cord. We hypothesized that the activation of α-adrenoceptors depresses low threshold-evoked synaptic transmission and inhibits pathways mediating PAD. Extracellular field potentials (EFPs) recorded in the deep dorsal horn assessed adrenergic modulation of population monosynaptic transmission, while dorsal root potentials (DRPs) recorded at root entry zone assessed adrenergic modulation of PAD. We found that noradrenaline (NA) and the α1-adrenoceptor agonists phenylephrine and cirazoline depressed synaptic transmission (by 15, 14 and 22%, respectively). DRPs were also depressed by NA, phenylephrine and cirazoline (by 62, 30, and 64%, respectively), and by the α2-adrenoceptor agonist clonidine, although to a lower extent (20%).
