The influence of secondary hyperparathyroidism (2 HPT) on the set point of the parathyroid hormone (PTH)-Ca(2+) curve is controversial. In vitro experiments have shown an increase in the set point. However, clinical studies with hemodialysis patients have provided a variety of results (increases, decreases and no changes in the set point have been reported). The present study was designed to in...
BACKGROUND Perchlorate (ClO4(-)) is an environmental contaminant known to disrupt the thyroid axis of many terrestrial and aquatic species. ClO4(-) competitively inhibits iodide uptake into the thyroid at the sodium/iodide symporter and disrupts hypothalamic-pituitary-thyroid (HPT) axis homeostasis in rodents. OBJECTIVE We evaluated the proposed mode of action for ClO4(-)-induced rat HPT axis...
The organization of the human metallothionein (MT) gene family is more complex than the commonly used mouse and rat models. The human MTs are encoded by a family of genes consisting of 10 functional and 7 nonfunctional MT isoforms. One objective of this study was to determine if the accumulation of MT protein in cultures of human proximal tubule (HPT) cells exposed to metals is similar to that ...
X-linked hypophosphatemic rickets (XLH) is a dominant disorder characterized by hypophosphatemia due to impaired renal tubular reabsorption of inorganic phosphate. Cardinal manifestations include defective calcification of cartilage and bone, growth retardation and resistance to phosphorus and vitamin D therapy. Although secondary hyperparathyroidism (HPT) is a common complication of treatment,...
Conventional microbiology methods used to detect bacteria include multiple cultures and identification processes, so the results of lab work are painstaking and time-consuming. In recent years, more and more tend to use the diagnostic tests which are based on DNA; hence, DNA diagnostic biosensors have been created to perform DNA identification better. In this study, GUS and hpt genes were used ...
Hyperparathyroidism Jaw-Tumour Syndrome (HPT-JT) is characterized by primary hyperparathyroidism (PHPT), maxillary/mandible ossifying fibromas and by parathyroid carcinoma in 15% of cases. Inactivating mutations of the tumour suppressor CDC73/HRPT2 gene have been found in HPT-JT patients and also as genetic determinants of sporadic parathyroid carcinoma/atypical adenomas and, rarely, typical ad...
The hyperbolic Pascal triangle HPT 4,q (q ≥ 5) is a new mathematical construction, which is a geometrical generalization of Pascal’s arithmetical triangle. In the present study we show that a natural pattern of rows of HPT 4,5 is almost the same as the sequence consisting of every second term of the well-known Fibonacci words. Further, we give a generalization of the Fibonacci words using the h...
Background: The field of parathyroidectomy (PTx) is complex and brings together many specialists. Even if the surgical approaches changed from classical to minimally invasive PTx, a good outcome is correlated with an adequate localization before and during PTx, while blood assays, such as parathormone (PTH) or 25-hydroxyvitamin D, become useful additional markers. Aim. Specific aspects related ...
Influence of HPT and Accumulative High-Pressure Torsion on the Structure and Hv of a Zirconium Alloy
The authors previously used the accumulative high-pressure torsion (ACC HPT) method for first time on steel 316, β-Ti alloy, and bulk metallic glass vit105. On low-alloyed alloys, in particular, zirconium alloy Zr-1%Nb, new was not used. This has a tendency to α → ω phase transformations at using simple HPT. When ACC HPT, transformation can be influenced greater extent. article studies sliding ...
It is important for mass storage system to distribute access requests dynamically and balanced between several metadata servers (MDS). Based on analyzing the features of metadata management in the mass storage system, this paper designs the structure of metadata management module, proposes the hash postfix table(HPT) based metadata management algorithm, uses HPT to adjust the distribution of ac...
