Abstract Conducting polymers are semiconductors whose applications cover a wide range of devices. Their versatility is due, in addition to other factors, properties that can be easily modulated according the intended application. It therefore important study and map electronic structure these materials for better correlation between properties. Electrochemical scanning tunneling spectroscopy (E...

Chalcone and stilbene synthases (CHS and STS) catalyze condensation reactions of p-coumaroyl-CoA and three C(2)-units from malonyl-CoA, but catalyze different cyclization reactions to produce naringenin chalcone and resveratrol, respectively. Condensing activities of wild-type CHS and STS as well as STS-C60S mutant were inhibited by iodoacetamide (Idm) and diethyl pyrophosphate (DPC). DPC also ...

Sodium Tanshinone IIA sulfonate (STS) is a derivative of Tanshinone IIA (Tan IIA). Tan IIA has been reported to possess neuroprotective effects against Alzheimer's disease (AD). However, whether STS possesses effect on AD remains unclear. This study aims to estimate whether STS could protect against scopolamine- (SCOP-) induced learning and memory deficit in Kunming mice. Morris water maze resu...

[Purpose] The purpose of this study was to compare the relative levels of activation of the gluteus medius (Gmed) and rectus femoris (RF) muscles during natural (N) sit-to-stand (STS) and STS with hip abduction (ABD) in young and elderly females. [Subjects] We recruited 15 healthy young females and 15 healthy elderly females. [Methods] The activities of the dominant lower extremity gluteus medi...

T cells play a central role in the recognition and elimination of foreign pathogens. Signals through the T cell receptor (TCR) control the extent and duration of the T cell response. To ensure that T cells are not inappropriately activated, signaling pathways downstream of the TCR are subject to multiple levels of positive and negative regulation. Herein, we describe two related proteins, Sts-1...

Calciphylaxis is a rare but life-threatening complication seen in dialysis patients. We report a case with calciphylaxis and severe secondary hyperparathyroidism. Sodium thiosulfate (STS) was used for treatment in this case. The painful skin ulcers improved significantly soon after treatment, with a slight reduction in the calcium-phosphorus product. Total parathyroidectomy was carried out 6 mo...

This paper describes the SAARSHEFF systems that participated in the English Semantic Textual Similarity (STS) task in SemEval2016. We extend the work on using machine translation (MT) metrics in the STS task by automatically annotating the STS datasets with a variety of MT scores for each pair of text snippets in the STS datasets. We trained our systems using boosted tree ensembles and achieved...

It is well known that some sera giving false positive reactions with the standard serological tests for syphilis (STS) show a pattern which is very seldom found in syphilitic sera, while in other falsely reacting sera the strength or pattern of the STS give no clue to specificity. Less attention seems to have been paid to the course of the STS titres in chronic positive STS reactors who are neg...

[Purpose] The purpose of this study was to compare the activation of the tibialis anterior (TA) and soleus (SOL) muscles during the sit-to-stand (STS) task with hip adduction and hip abduction in elderly females. [Subjects] We recruited 16 healthy elderly females with no pain in the knee joint and no other orthopedic problems of the lower limbs. [Methods] The activities of the dominant lower ex...
