PHT-splines (polynomials splines over hierarchical T-meshes) are a generalization of B-splines over hierarchical T-mesheswhich possess a very efficient local refinement property. This property makes PHT-splines preferable in geometric processing, adaptive finite elements and isogeometric analysis. In this paper, we first make analysis of the previously constructed basis functions of PHT-splines...

Portal hypertension (PHT) is a rare complication associated with choledochal cysts. Management issues of PHT patients are inadequately addressed, as its incidence is low and underlying causes variable. We report three cases of choledochal cyst with PHT. All patients had type IVa choledochal cysts, and the causes of PHT were secondary biliary cirrhosis (SBC) (two cases) and alcoholic liver disea...

BACKGROUND The pressure half-time (PHT) method has been widely used to estimate mitral valve area (MVA) in patients with mitral stenosis (MS), in the belief that this simple method provides reliable information on true MVA. However, its limitation has been repeatedly recognized under different circumstances. The aim of this study was to evaluate the effect of cardiac rhythm on PHT-derived MVA c...

Action of antiepileptic drugs in immature brain may differ from that in adult brain. The aim of our study was to study an anticonvulsant action of lamotrigine and phenytoin, i.e. two drugs active against partial seizures in adult experimental animals as well as human patients, in a model of simple partial seizures in immature rats. Epileptic foci were induced by local application of bicuculline...

Vimalamitra’s (ca. the 8th–9th cent.) *Āryaprajñāpāramitāhṛdayaṭīkā (hereafter PHT) sparks interest not only because of its detailed verbal commentary on Prajñāpāramitāhṛdaya or Heart Sūtra but also it developed various philosophical arguments. However, these arguments have always been clear due to difficulty surrounding Tibetan translation and complexity discussion. For instance, in 2021, Math...

Plasmon hybridization theory (PHT) is an analytical model developed for understanding plasmonic interactions within complex metallic nanostructures, and gives a useful insight for optimizing design parameters. However, this theory is based on the electrostatic limit, which restricts the model to nanostructures much smaller than the free space wavelength of light. Here, we extend the PHT to inco...

The asymmetric unit of the title compound, [Zn(C(7)H(8)N(4)S)(2)](NO(3))(2)·2H(2)O, contains two Zn(pht)(2) cations (pht is pyridine-2-carbaldehyde thio-semicarbazone), four nitrate anions and four water mol-ecules. In the cations, each Zn(II) ion adopts a distorted octa-hedral coordination geometry, being chelated by two tridentate pht ligands. In the crystal, the cations, anions and water mol...

INTRODUCTION The aim of this report is to present a severe case of phenytoin (PHT)-induced gingival hyperplasia in a Saudi patient. MATERIALS AND METHODS A 12-year-old male epileptic patient, undergoing PHT therapy, was diagnosed clinically with severe gingival hyperplasia. His treatment consisted meticulous oral care and weekly professional prophylaxis. The patient was advised oral folic aci...

The asymmetric unit of the title complex, [Ni(pht)(2)(pn)(2)] (pht is 5,5-diphenyl-hydantoinate and pn is propane-1,2-diamine) or [Ni(C(15)H(11)N(2)O(2))(2)(C(3)H(10)N(2))(2)], contains one-half [Ni(pht)(2)(pn)(2)] mol-ecule. The Ni(II) atom is situated on a crystallographic center of inversion and shows a distorted octa-hedral coordination geometry. A three-dimensional network structure is ass...

This paper forms the second part of the debate on prehospital thrombolysis (PHT). It is argued that large scale studies have failed to show a benefit for PHT, even when the time saved over conventional treatment was considerably greater than would be the case in the UK urban setting. In practice, a relatively small proportion of the total population receiving thrombolysis would receive PHT. Oth...
