Tertiary Hyperparathyroidism (HPT) is an uncommon condition that affects patients with secondary HPT after a successful kidney transplant. Bone alterations are the main consequences of this endocrine condition, including the development of an osteolytic lesion called brown tumour. This paper reports an unusual case of multiple brown tumours located in the maxilla and mandible in a 58-year-old r...

In this work, we have proposed a model for the ultimate physical limit on the sensitivity of the heterojunction bipolar phototransistors (HPTs). Based on our modeling we have extracted the design criteria for the HPT for high sensitivity application. HPT with the submicron emitter and base area has the potential to be used for the low number photon resolving in near-infrared (NIR) wavelength. H...

We investigated the involvement of the HRPT2 gene by loss of heterozygosity analysis and direct sequencing in a kindred with hyperparathyroidism-jaw tumor syndrome (HPT-JT) and three kindreds with familial isolated primary hyperparathyroidism (FIHP). Seven patients with sporadic parathyroid cancers and 35 with parathyroid adenomas with no family history of primary hyperparathyroidism or HPT-JT ...

Abstract This paper focuses on the differential-mode (DM) noise of high-power thyristor (HPT) trigger circuit with switching-mode power supply (SMPS) in capacitive pulsed (CPPS). Parasitic parameter models components are discussed and analyzed. Based parasitic components, a DM prediction model HPT SMPS is developed. The generation mechanism propagation paths investigated. To reduce noise, techn...

A markerless genetic exchange system was successfully established in Methanosarcina mazei strain Gö1 using the hpt gene coding for hypoxanthine phosphoribosyltransferase. First, a chromosomal deletion mutant of the hpt gene was generated conferring resistance to the purine analog 8-aza-2,6-diaminopurine (8-ADP). The nonreplicating allelic exchange vector (pRS345) carrying the pac-resistance cas...

The pressure influence on the α → ω transformation in Ti–Co alloys has been studied during high pressure torsion (HPT). The α→ω allotropic transformation takes place at high pressures in titanium, zirconium and hafnium as well as in their alloys. The transition pressure, the ability of high pressureω-phase to retain after pressure release, and the pressure interval where α andω phases coexist d...

Few studies have included subjects with the propensity to reach old age in good health, with the aim to disentangle mechanisms contributing to staying healthier for longer. The hypothalamic-pituitary-thyroid (HPT) axis maintains circulating levels of thyroid stimulating hormone (TSH) and thyroid hormone (TH) in an inverse relationship. Greater longevity has been associated with higher TSH and l...

A new genetic technique for constructing mutants of Methanosarcina acetivorans C2A by using hpt as a counterselectable marker was developed. Mutants with lesions in the hpt gene, encoding hypoxanthine phosphoribosyltransferase, were shown to be >35-fold more resistant to the toxic base analog 8-aza-2,6-diaminopurine (8ADP) than was the wild type. Reintroduction of the hpt gene into a Delta hpt ...

The inactivation of spores of four low-acid food spoilage organisms by high pressure thermal (HPT) and thermal-only processing was compared on the basis of equivalent thermal lethality calculated at a reference temperature of 121.1°C (F(z)(121.1)(°)(C, 0.1 MPa or 600 MPa)) and characterized as synergistic, not different or protective. In addition, the relative resistances of spores of the diffe...

Zinc oxide (ZnO) with a rocksalt crystal structure is attractive because of the bandgap which lies in range visible light absorption (1.2–2.6 eV). However, not stable at ambient pressure and temperature according to an equilibrium phase diagram. Nevertheless, this study demonstrates, for first time, that it possible realize 100% fraction temperature. ZnO powder initially processed by severe pla...
