Thyrotropin Receptor Blocking Antibodies.

2018

AbstractAutoantibodies (Ab) against the thyroid-stimulating hormone receptor (TSHR) are frequently found in autoimmune thyroid disease (AITD). Autoantibodies to the TSHR (anti-TSHR-Ab) may mimic or block the action of TSH or be functionally neutral. Measurement of anti-TSHR-Ab can be done either via competitive-binding immunoassays or with functional cell-based bioassays. Antibody-binding assays do not assess anti-TSHR-Ab functionality, but rather measure the concentration of total anti-TSHR binding activity. In contrast, functional cell-based bioassays indicate whether anti-TSHR-Ab have stimulatory or blocking activity. Historically bioassays for anti-TSHR-Ab were research tools and were u…

Follow-Up and Relook Hysteroscopy

2020

Intra-uterine adhesions (IUAs) after initial treatment in patients with Asherman’s Syndrome are one of the main challenging issues in the gynecological practice, since its incidence has been increasing over the last few decades, with a reported recurrence rate up to 30%. Asherman syndrome is characterized by variable scarring inside the uterine cavity that can lead to partial or complete dysfunction of the endometrium with impairment of fertility and menstrual pattern (amenorrhea and hypomenorrhea).

OP0048 Outcomes in Systemic Lupus Erythematous (SLE) Patients Treated with Belimumab in Clinical Practice Settings: Results from the Observe Study in…

2014

Background Large-scale clinical trials have demonstrated clinical efficacy of belimumab in SLE patients. Objectives This study examined the clinical outcomes associated with belimumab in clinical practice settings in Germany. Methods OBSErve (GSK 117214) is a multi-center retrospective medical chart review study. Twenty-one rheumatologists from Germany treating >10 SLE-patients annually and with at least >5 yrs of practice experience were selected for data reporting. Adult SLE patients meeting the ACR classification criteria who received belimumab (10mg/kg) as part of usual care were identified for chart abstraction. Index date was the date of belimumab initiation. The primary outcome measu…

Stability of Cannabinoids in Hair Samples Exposed to Sunlight

2000

It has been well recognized that hashish and marihuana lose potency during storage because of a decrease in the content of tetrahydrocannabinol (THC), which is the major psychoactive constituent of cannabis (1). The effect of oxygen on stored plant and resin materials or solutions of pure cannabinoids seems much less significant than that of higher temperatures (≥37 °C) or light (2)(3)(4)(5)(6)(7). A few data are available on the stability of THC and major metabolites in blood (8)(9)(10)(11). However, the stability of cannabinoids in the hair shaft has not been addressed, although scalp hair represents one of the most exposed parts of the body. Therefore, a study was performed to elucidate …

The determination of trace element concentrations in fly ash samples using ultrasound-assisted digestion followed with inductively coupled plasma opt…

2009

A method of ultrasound-assisted digestion followed by inductively coupled plasma optical emission spectrometry (ICP-OES) used for the determination of trace element (chromium, copper, lead, nickel, vanadium and zinc) concentrations in fly ash samples was developed. All the measurements were performed in robust plasma conditions. Ultrasound-assisted digestion procedures using digestion solutions of aqua regia and hydrofluoric acid (HF) resulted in recovery rates of over 80% for all the analyte elements. Ultrasound-assisted two-step digestion with digestion solutions of 6 mL of HNO₃(Step 1) and 3 mL of HNO₃+ 3 mL of HF (Step 2) resulted in recovery rates of over 92% for all the analyte elemen…

An ultrasound-assisted digestion method for the determination of toxic element concentrations in ash samples by inductively coupled plasma optical em…

2007

method of ultrasound-assisted digestion followed by inductively coupled plasma optical emission spectrometry (ICP-OES) used for the determination of toxic element concentrations (arsenic, barium, cobalt, copper, lead, nickel, strontium, vanadium and zinc) in ash samples was developed. All the measurements were performed in robust plasma conditions which were tested by measuring the Mg(II) 280.270 nm/Mg(I) 285.213 nm line intensity ratios. The highest line intensity ratios were observed when a nebulizer gas flow of 0.6 L minˉ¹, auxiliary gas flow of 0.2 L minˉ¹ and plasma power of 1400 W were used for radially viewed plasma. The analysis of SRM 1633b showed that the ultrasound-assisted metho…

A new aid modality for Africa

2013

Preprint of an article published in the Journal of Economic Policy Reform with the title:“Stimulating economic growth in the least developed countries: Direct cash transfers for the retired via mobile phones,” The result of current aid policies is that only a small percentage of foreign aid reaches the poorest of the poor in the least developed countries. Current trends of urbanisation and self-reliance place elderly people in an increasingly difficult situation. This paper aims to stimulate debate by introducing an alternative mechanism for foreign aid. With the help of an economic model, we demonstrate how direct cash transfers to elderly people can spur economic growth. Targeting all eld…

Effects of Personal Traits on Generation Y Consumers' Attitudes Toward the Use of Mobile Devices for Communication and Commerce

2012

The purpose of this study was to investigate the effects of young adult consumers’ personal traits (high-tech involvement, experiment proclivity, and fashion/brand leadership) on their perceptions of and attitudes toward using mobile devices for communications and commerce. The integrated stimulus-organism-responses paradigm (Fiore & Kim, 2007) served as the overarching framework, combining the uses and gratifications theory (Blumler & Katz, 1974) and the extended technology acceptance model (Kim, Ma, & Park, 2009). A convenience sample of 504 college students in 2 U. S. universities provided usable responses to our survey. Causal modeling analysis results showed that personal trait varia…

An EEMD Aided Comparison of Time Histories and Its Application in Vehicle Safety

2017

In the context of signal processing, the comparison of time histories is required for different purposes, especially for the model validation of vehicle safety. Most of the existing metrics focus on the mathematical value only. Therefore, they suffer the measuring errors, disturbance, and uncertainties and can hardly achieve a stable result with a clear physical interpretation. This paper proposes a novel scheme of time histories comparison to be used in vehicle safety analysis. More specifically, each signal for comparison is decomposed into a trend signal and several intrinsic mode functions (IMFs) by ensemble empirical mode decomposition. The trend signals reflect the general variation a…
