Focused Vibrotactile Stimulation with Cueing Effect on Freezing of Gait in Parkinson’s Disease: Two Case Reports

Xiu Sheng Tan,Floyd Pierres,Alex Dallman-Porter,William Hardie-Brown,권겸일 대한파킨슨병및이상운동질환학회 2021 Journal Of Movement Disorders Vol.14 No.3

Freezing of gait (FOG) is a common occurrence in patients with Parkinson’s disease (PD) that leads to significant limitations in mobility and increases risk of falls. Focused vibrotactile stimulation and cueing are two methods used to alleviate motor symptoms, including FOG, in patients with PD. While effective on their own, the effect of combining both focused vibrotactile stimulation and cueing has yet to be investigated. Two patients, both with a history of PD, suffered from frequent FOG episodes that failed to respond adequately to medication. A novel vibrotactile stimulation device that delivered rhythmic kinesthetic stimuli onto the sternum successfully reduced FOG episodes in both patients and drastically improved their mobility as measured by the Timed Up and Go test. We found that a combination of focused vibrotactile stimulation and cueing was effective in reducing FOG episodes in two patients with PD. Further well-designed prospective studies are needed to confirm our observations.

Guo Jeng Tan,Sheng Hui Kioh,Sumaiyah Mat,Maw Pin Tan,Shirley Huey Ling Chan,Jacintha Mei Ying Lee,Yee Wen Tan 대한노인병학회 2023 Annals of geriatric medicine and research Vol.27 No.4

Background: Knee osteoarthritis (OA) is a common cause of physical disability among older adults. While established risk factors for knee OA include age and increased body weight, few studies have examined psychosocial risk factors or progression of knee OA. Methods: The Promoting Independence in our Seniors with Arthritis study recruited participants aged 65 years and over from orthopedic outpatients and community engagement events. Participants were invited to annual visits during which knee OA symptoms were assessed with the Knee Injury and Osteoarthritis Outcome Score (KOOS), social network using the 6-item Lubben Social Network Scale and anxiety and depression using the Hospital Anxiety and Depression scale. Knee OA worsening was defined by a 5% reduction in mean KOOS scores at the last visit compared to the first visit. Results: Data were available from 148 participants, mean age 66.2±6.5 years and 74.1% female, of whom 28 (18.9%) experienced OA worsening over a median follow-up period of 29 months. Univariate analyses revealed that age, sex, height, grip strength, and social network were associated with OA worsening. Social network remained statistically significantly associated with OA worsening after adjustment for age and sex difference (odds ratio=0.924; 95% confidence interval, 0.857–0.997). The relationship between social network and OA worsening were attenuated by both depression and handgrip strength at baseline. Conclusion: Psychological status and muscle strength may be modifiable risk factors for social network which may in turn prevent knee OA worsening and should be targeted in future intervention studies.

Analyzing the Impact of Supply Noise on Jitter in GBPS Serial Links on a Merged I/O-Core Power Delivery Network

Tan, Fern-Nee,Lee, Sheng Chyan The Korean Microelectronics and Packaging Society 2013 마이크로전자 및 패키징학회지 Vol.20 No.4

In this paper, the impact of integrating large number of I/O (Input-Output) and Core power Delivery Network (PDN) on a 6 layers Flip-Chip Ball Grid Array (FCBGA) package is investigated. The impact of core induced supply noise on high-speed I/O interfaces, and high-speed I/O interface's supply noise coupling to adjacent high-speed I/O interfaces' jitter impact are studied. Concurrent stress validation software is used to induce SSO noise on each individual I/O interfaces; and at the same time; periodic noise is introduced from Core PDN into the I/O PDN domain. In order to have the maximum coupling impact, a prototype package is designed to merge the I/O and Core PDN as one while impact on jitter on each I/O interfaces are investigated. In order to understand the impact of the Core to I/O and I/O to I/O noise, the on-die noise measurements were measured and results were compared with the original PDN where each I/O and Core PDN are standalone and isolated are used as a benchmark.

Gadoxetate magnetic resonance imaging (MRI) is widely used in clinical practice for liver imaging. For optimal use, we must understand both its advantages and limitations. This article is the outcome of an online advisory board meeting and subsequent discussions by a multidisciplinary group of experts on liver diseases across the Asia-Pacific region, first held on September 28, 2020. Here, we review the technical considerations for the use of gadoxetate, its current role in the management of patients with hepatocellular carcinoma (HCC), and its relevance in consensus guidelines for HCC imaging diagnosis. In the latter part of this review, we examine recent evidence evaluating the impact of gadoxetate on clinical outcomes on a continuum from diagnosis to treatment decision-making and follow-up. In conclusion, we outline the potential future roles of gadoxetate MRI based on an evolving understanding of the clinical utility of this contrast agent in the management of patients at risk of, or with, HCC.

Feasibility of Laser-Induced Breakdown Spectroscopy (LIBS) for Classification of Sea Salts

Tan, Man Minh,Cui, Sheng,Yoo, Jonghyun,Han, Song-Hee,Ham, Kyung-Sik,Nam, Sang-Ho,Lee, Yonghoon Society for Applied Spectroscopy 2012 Applied spectroscopy Vol.66 No.3

<P>We have investigated the feasibility of laser-induced breakdown spectroscopy (LIBS) as a fast, reliable classification tool for sea salts. For 11 kinds of sea salts, potassium (K), magnesium (Mg), calcium (Ca), and aluminum (Al), concentrations were measured by inductively coupled plasma-atomic emission spectroscopy (ICP-AES), and the LIBS spectra were recorded in the narrow wavelength region between 760 and 800 nm where K (I), Mg (I), Ca (II), Al (I), and cyanide (CN) band emissions are observed. The ICP-AES measurements revealed that the K, Mg, Ca, and Al concentrations varied significantly with the provenance of each salt. The relative intensities of the K (I), Mg (I), Ca (II), and Al (I) peaks observed in the LIBS spectra are consistent with the results using ICP-AES. The principal component analysis of the LIBS spectra provided the score plot with quite a high degree of clustering. This indicates that classification of sea salts by chemometric analysis of LIBS spectra is very promising. Classification models were developed by partial least squares discriminant analysis (PLS-DA) and evaluated. In addition, the Al (I) peaks enabled us to discriminate between different production methods of the salts.</P>

Sheng Zeng,Yuan Shen,Bing Sun,Kaixuan Tan,Shuwen Zhang,Wenhao Ye 한국원자력학회 2022 Nuclear Engineering and Technology Vol.54 No.4

The pore structure of uranium-bearing sandstone is one of the critical factors that affect the uraniumleaching performance. In this article, uranium-bearing sandstone from the Yili Basin, Xinjiang, China, wastaken as the research object. The fractal characteristics of the pore structure of the uranium-bearingsandstone were studied using mercury intrusion experiments and fractal theory, and the fractaldimension of the uranium-bearing sandstone was calculated. In addition, the effect of the fractal characteristics of the pore structure of the uranium-bearing sandstone on the uranium leaching kinetics wasstudied. Then, the kinetics was analyzed using a shrinking nuclear model, and it was determined that therate of uranium leaching is mainly controlled by the diffusion reaction, and the dissolution rate constant(K) is linearly related to the pore specific surface fractal dimension (DS) and the pore volume fractaldimension (DV). Eventually, fractal kinetic models for predicting the in-situ leaching kinetics wereestablished using the unreacted shrinking core model, and the linear relationship between the fractaldimension of the sample's pore structure and the dissolution rate during the leaching was fitted.

Shengli Ma,Yizhuo Han,Yisheng Tan 한국공업화학회 2011 Journal of Industrial and Engineering Chemistry Vol.17 No.4

Water-gas shift coupling with methanation was carried out over metal oxide modified nanorod-NiO/γ-Al_2O_3 catalysts prepared by grind-mixing method in a continuous flow type fixed-bed reactor. The effects of promoter type, Co_3O_4 content, and reaction pressure were investigated. From the experimental results, Co_3O_4 modified nanorod-NiO/g-Al_2O_3 catalyst exhibited better activity than NiO–CuO/g-Al_2O_3and NiO–Fe_2O_3/g-Al_2O_3 with molar ratio of CO/H_2/H_2O = 3:1:1 at 593 K and atmospheric pressure. The addition of 10 wt%Co_3O_4 to nanorod-NiO/γ-Al_2O_3 catalyst was optimum. The CO conversion of 50 wt%NiO–10 wt%Co_3O_4/γ-Al_2O_3 catalyst was 7.8% and the CH_4 selectivity reached 83.2%. The NiO–MO_x/γ-Al_2O_3 catalysts were analyzed by X-ray diffraction, temperature programmed reduction and thermogravimetry techniques.
