The study aimed to evaluate the diagnostic accuracy of intraoperative intact parathyroid hormone (IO-iPTH) in patients with secondary hyperparathyroidism (HPT). The cut-off for IO-iPTH monitoring remains unknown. This was a single-center retrospective review of 226 consecutive patients (107 males and 119 females) who underwent parathyroidectomy data for secondary HPT between May 2010 and March ...

For the first time, tribological behaviour of 316 L stainless steel (316 SS) additively manufactured via laser powder bed fusion (L-PBF) with ultrafine- and nano-grains obtained from high-pressure torsion (HPT) processing has been investigated. The pin-on-disk dry sliding wear test results demonstrate enhancement performance after HPT processing, as indicated by consistently lower coefficient f...

Ternary Mg–Y–Zn alloys have attracted considerable attention due to their excellent mechanical properties and unique microstructures. Microstructural variation and the resulting mechanical properties can be affected by various processing routes, particularly those involving severe plastic deformation of a cast billet. The following approach was used in this work to perform a comparative study: ...

Sir, Progressive image technologies are improving the accuracy for determining the localization of enlarged parathyroid glands (PTGs) in hyperparathyroidism (HPT). However, the identification of an unusually located cervical nodule as an ectopic PTG remains uncertain. The measurement of parathyroid hormone (PTH) in the aspirated material with a fine needle has shed light on this diagnostic diff...

The study of the fundamentals ? ? ? and ? phase transformations induced by high-pressure torsion (HPT) in Ti–Nb-based alloys is presented current work. Prior to HPT, three with 5, 10, 20 wt% Nb were annealed temperature range 700–540°C order obtain (? + ?)-phase state a different amount ?-phase. samples for long time reach equilibrium content ?-solid solution. Scanning electron microscope (SEM)...

An important aspect of machine learning (ML) involves controlling the process for ML method in question to maximize its performance. Hyperparameter tuning (HPT) selecting suitable parameters that control process. Given HPT can be conceptualized as a black box optimization problem subject stochasticity, simulation (SO) methods appear well suited this purpose. Therefore, we conceptualize discrete...

The Hybrid Phenomena Theory (HPT) is a framework for formalizing how dynamic state space models of physical systems are built from first principles. The HPT descends from the Qualitative Process Theory (QPT), [Forb us, 1984], from which it inherits basic concepts like views, phenomena and influences. However, the HPT redefines some of these concepts in a more strict manner in order to represent...

A cortical lesion of the tibial diaphysis in a young patient poses a diagnostic challenge to the clinician. Brown tumors, although not very common, may mimic malignancies on radiographs. Brown tumors are destructive lytic lesions of the bone due to increased osteoclastic activity and fibroblastic proliferation in patients with uncontrolled hyperparathyroidism (HPT). They occur after primary or ...

Obesity is a major public health issue worldwide. Current pharmacological treatments are largely unsuccessful. Determining the complex pathways that regulate food intake may aid the development of new treatments. The hypothalamic-pituitary-thyroid (HPT) axis has well-known effects on energy expenditure, but its role in the regulation of food intake is less well characterised. Evidence suggests ...
