Acute Effects of Episodic PCB Congeners on the Hypothalamo -Pituitary-Thyroid (Hpt) Axis in Weanling Female Rats
… PCBs can cause alterations in the HPT axis in immature animals. The data indicate that ortho-PCBs 95 or 101 cause secondary or pituitary-related hypothyroidism. There is also evidence that these PCBs may be affecting the HPT-axis through multiple mechanisms.

Processing of aluminium and titanium alloys by severe plastic deformation
… pressing (ECAP) and high pressure torsion (HPT) were considered as very important SPD techniques. Very high deformation is applied to the samples in ECAP and HPT which refines the grain size and enhances the properties of materials.<br/>In the present research, the evolution of homogeneity …

Using the health policy triangle framework to describe local, regional and national healthcare policy changes within Ireland's diverse healthcare settings
… by Walt and Gilson’s health policy triangle (HPT). The HPT model is a policy analysis framework universally used and applied in the literature to analyse various health-related issues, mainly at national or international level. Robust research is required to seek a greater understanding of the …

A Needs Assessment Of The Knowledge, Skills And Use Of Finance Competencies By Human Performance Technology Practitioners
… questions: (1) What finance knowledge do HPT practitioners possess? and (2) How do HPT practitioners use their finance knowledge and skills in their work? An online survey was administered to obtain answers directly from practicing HPT professionals. Sixty seven HPT practitioners …

Effect of cell- and species-differences in the expression of drug metabolism enzymes on chemical-induced injury to the rat and human kidney
… Freshly isolated human proximal tubular (hPT) cells expresses CYP4A11, GSTA, GSTP, and GSTT but not GSTM. Tri and DCVC were toxic to freshly isolated hPT cells in a manner not affected by P450 or cysteine S-conjugate β-lyase inhibition. Tri was metabolized to its GSH conjugate but not to …

Severe plastic deformation in highly immiscible copper alloys: self-organization
… angular pressing (ECAP), high pressure torsion (HPT), high energy ball milling (BM), accumulative roll bonding (ARB), are well known to refine the microstructures of metals and alloys into non-equilibrium states with nanometer-size grains, and they are gaining widespread interest for processing …

Patterns of HIV, TB, and non-communicable disease multi-morbidity in an informal peri-urban setting in Cape Town, South Africa
… (TB), diabetes (T2DM), and hypertension (HPT) were identified between Sept 2012-May 2013 on electronic databases. Using unique patient identifiers, drugs prescribed across all facilities in the province were linked to each patient and each drug class assigned a condition. RESULTS: These 4 …

Elucidating Collagen Degradation Synergy between Col G and Col H from Hathewaya (Clostridium) histolytica and Identifying novel structural features in HPT and REC domains from VarS histidine kinase in V. alginolyticus
… used to show that Cys892 is fairly conserved in HPT domains across species. qRT-PCR showed that in the presence of menadione VarS induced transcription of sRNA2 was slightly downregulated. This study speculates that Cys883/Cys892 disulfide bond stops collagenase expression in the presence of …

Stress response genes in the human proximal tubules
… previously with mortal human proximal tubule (HPT) cells, where acute stress by all three stimuli elicited marked increases in hsp 27, hsp 60 and hsp 70 mRNA and protein. The basal levels of expression of hsp 27 and hsp 60 in the HK-2 cells were elevated compared to unstressed HPT cells. These …

A Case Study Of The Impact Of A Sytematic Evaluation Process In A Graduate Medical Education Residency Program
… methodology. Human Performance Technology (HPT) offers models suitable for residency program evaluation as well as trained evaluators who are experts in evaluation. Leaders in the field of HPT have called for empirical studies to examine the impact of HPT models in a variety of contexts. …

Hydrostatic Pressure Testing of a Square-Cross Section Stainless Steel Propellant Tank Manufactured Using Selective Laser Sintering
… by performing a hydrostatic pressure test (HPT) of a metal SLS manufactured propellant tank, constructed for a nano-satellite of the cubesat class. Strain measurements from twelve strain gage locations on the propellant tank were recorded. A finite element analysis (FEA) model, which assumes …

Pattern and distribution of peripheral arterial disease in diabetic patients with critical limb ischemia (Rutherford Clinical Category 4-6)
… and risk factor combinations [ Group1 = (DM, HPT, Dyslipidemia); Group 2= (DM, HPT, dyslipidemia, exsmoker); Group 3 = (DM, HPT, dyslipidemia, smoker)]. The three risk combination groups formed the majority of our study group (79%).

Glycoprotein hormone receptors in sea lamprey (Petromyzon marinus): Identification, characterization and implications for the evolution of the vertebrate hypothalamic-pituitary-gonadal/thyroid axes
… (HPG) and hypothalamic-pituitary-thyroid (HPT) endocrine axes involve specific interaction between pituitary glycoprotein hormones GpH (lutropin LH, follitropin FSH, thyrotropin TSH) and glycoprotein hormone receptors GpH-R (LH-R, FSH-R and TSH-R respectively).</p><p>GpHs and GpH-Rs …

Polychlorinated biphenyl effects on avian hepatic enzyme induction and thyroid function
… PCBs affect the hypothalamic-pituitary-thyroid (HPT) axis in quail, and activation of the HPT axis appears to be inhibited in mice. Overall, quail showed a lesser response than mice to equivalent doses of Aroclor 1254, so it appears that birds may be less vulnerable to PCBs than mammals.

Signaling between Two Sensor Kinases Controls Biofilms and Host Colonization in a Bacterial Symbiont
… a single non-enzymatic domain within SypF, the HPt domain, was critical in vivo. Remarkably, this domain within SypF directly interacted with RscS, permitting a bypass of RscS's own HPt domain and SypF's enzymatic function. These unique findings represent the first in vivo example of a …

The effects of induced hypothyroidism on the glucocorticoid stress response in Japanese quail (Coturnix japonica)
… between the hypothalamic-pituitary thyroid (HPT) and hypothalamic-pituitary adrenal (HPA) axes of control. I used the thyroid inhibitor ammonium perchlorate (AP) for 2 weeks and 5 weeks to induce two states of decreased thyroid function: a thyroid challenged state, in which birds have …
