“…In the present study, the control group also showed pain improvement post-intervention, but the degree of pain improvement was negligible compared with that in the rESWT group, in which the difference was statistically significant. The placebo effects of ESWT have been suggested in various musculoskeletal conditions, including shoulder pain and soft-tissue lesions [ 24 25 26 ]. The placebo and time effect can influence the results of pain improvement in a placebo group [ 27 ], but in the present study, the placebo effect seemed minimal.…”

ObjectiveTo investigate the effect of radial extracorporeal shock wave therapy (rESWT) on hemiplegic shoulder pain (HSP) syndrome.MethodsIn this monocentric, randomized, patient-assessor blinded, placebo-controlled trial, patients with HSP were randomly divided into the rESWT (n=17) and control (n=17) groups. Treatment was administered four times a week for 2 weeks. The visual analogue scale (VAS) score and Constant-Murley score (CS) were assessed before and after treatment, and at 2 and 4 weeks. The Modified Ashworth Scale and Fugl-Meyer Assessment scores and range of motion of the shoulder were also assessed.ResultsVAS scores improved post-intervention and at the 2-week and 4-week follow-up in the intervention group (p<0.05). Respective differences in VAS scores between baseline and post-intervention in the intervention and control groups were –1.69±1.90 and –0.45±0.79, respectively (p<0.05), between baseline and 2-week follow-up in the intervention and control groups were –1.60±1.74 and –0.34±0.70, respectively (p<0.05), and between baseline and 4-week follow-up in the intervention and control groups were –1.61±1.73 and –0.33±0.71, respectively (p<0.05). Baseline CS improved from 19.12±11.02 to 20.88±10.37 post-intervention and to 20.41±10.82 at the 2-week follow-up only in the intervention group (p<0.05).ConclusionrESWT consisting of eight sessions could be one of the effective and safe modalities for pain management in people with HSP. Further studies are needed to generalize and support these results in patients with HSP and a variety conditions, and to understand the mechanism of rESWT for treating HSP.

“…Arsenic (As) is known as one of the most toxic chemical elements at very low concentrations, contamination of natural waters by inorganic arsenic (As) has dire consequences for public health all around the world because of its potential synonymy with toxicity. 1,2 The release of As can occur naturally from geothermal and groundwater, 3 or by anthropogenic activities, such as mining, 4 feed additives 5 and wood preservation. 6 High As concentrations in groundwater have been found in Argentina, Bangladesh, Chile, China, Hungary, Mexico, West Bengal (India), and Vietnam.…”

“…The bacterial biosensor demonstrates a quantitative range from 10 to 500 μg·L −1 of As 3+ in 3 h reaction time. The shelf life for this biosensor is about 9 days in 4 °C and 3–5 days at room temperature [ 136 ]. In addition, biosensors including thermoresponsive magnetic nanobiosensors using green fluorescent protein-tagged sensor proteins [ 137 ], metallothionein-based biosensor [ 138 ], and multicolor fluorescent sulphur doped carbon dots-based sensor [ 139 ] are also used for detecting As 3+ in water sources.…”

Practical Application of Aptamer-Based Biosensors in Detection of Low Molecular Weight Pollutants in Water Sources

Water pollution has become one of the leading causes of human health problems. Low molecular weight pollutants, even at trace concentrations in water sources, have aroused global attention due to their toxicity after long-time exposure. There is an increased demand for appropriate methods to detect these pollutants in aquatic systems. Aptamers, single-stranded DNA or RNA, have high affinity and specificity to each of their target molecule, similar to antigen-antibody interaction. Aptamers can be selected using a method called Systematic Evolution of Ligands by EXponential enrichment (SELEX). Recent years we have witnessed great progress in developing aptamer selection and aptamer-based sensors for low molecular weight pollutants in water sources, such as tap water, seawater, lake water, river water, as well as wastewater and its effluents. This review provides an overview of aptamer-based methods as a novel approach for detecting low molecular weight pollutants in water sources.
