In this paper, we present a new open source dynamic quadruped robot, PADWQ (pronounced pa-dook), which features 12 torque controlled quasi direct drive joints with high control bandwidth, as well as onboard depth sensor and GPU-equipped computer that allows for a highly dynamic locomotion over uncertain terrains. In contrast to other dynamic quadruped robots based on custom actuator and machined metal structural parts, the PADWQ is entirely built from off the shelf components and standard 3Ddoi:10.3390/app11093762 doaj:d7169e734c1a40b2ba9b7ddd6509894e fatcat:dw4uziffjnbyjom256czm7oi7y

To make sure that the plastic structural parts can withstand the stress of dynamic locomotion, we performed finite element analysis (FEA) on leg structural parts as well as a continuous walking test using the physical robot, both of which the robot has passed successfully. We hope this work to help a wide range of researchers and engineers that need an affordable, highly capable and easily customizable quadruped robot.
Photoacoustic (PA) imaging can revolutionize medical ultrasound by augmenting it with molecular information. However, clinical translation of PA imaging remains a challenge due to the limited viewing angles and imaging depth. Described here is a new robust algorithm called Superiorized Photo-Acoustic Non-NEgative Reconstruction (SPANNER), designed to reconstruct PA images in real-time and to address the artifacts associated with limited viewing angles and imaging depth. The method utilizesdoi:10.1109/tmi.2021.3068181 pmid:33755561 fatcat:uh6url3jajf5fpyksk477m3ikq

A fast superiorized conjugate gradient algorithm is used for inversion. SPANNER is compared to three reconstruction algorithms: delay-and-sum (DAS), universal back-projection (UBP), and model-based reconstruction (MBR). All four algorithms are applied to both simulations and experimental data acquired from tissue-mimicking phantoms, ex vivo tissue samples, and in vivo imaging of the prostates in patients. Simulations and phantom experiments highlight the ability of SPANNER to improve contrast to background ratio by up to 20 dB compared to all other algorithms, as well as a 3-fold increase in axial resolution compared to DAS and UBP. Applying SPANNER on contrast-enhanced PA images acquired from prostate cancer patients yielded a statistically significant difference before and after contrast agent administration, while the other three image reconstruction methods did not, thus highlighting SPANNER's performance in differentiating intrinsic from extrinsic PA signals and its ability to quantify PA signals from the contrast agent more accurately.

Some amount of CuO was reduced to Cu2O by treating glucose into the solution, thereby preparing TiO2/CuxO complex. The obtained TiO2/CuxO complex showed advanced phtocatalytic activity under the sun light compared with the P-25 sample. In addition, the the TiO2/CuxO complex showed excellent antipathogenic effect.

Current treatments for osteoporosis were prevention of progression, yet it has been questionable in the stimulation of bone growth. The mesenchymal stem cells (MSCs) treatment for osteoporosis aims to induce differentiation of bone progenitor cells into bone-forming osteoblasts. We investigate whether human umbilical cord blood (hUCB)-MSCs transplantation may induce bone regeneration for osteoporotic rat model induced by ovariectomy. The ovariectomized (OVX) group (n = 10) and OVX-MSCs group (ndoi:10.1016/j.afos.2018.08.003 pmid:30775550 pmcid:PMC6362973 fatcat:gjzmdcvq2rhrzaenkh4inu4yfa

After a femoral defect was made at 9 months, Sham group and OVX group were injected with Hartmann solution, while the OVX-MSCs group was injected with Hartmann solution containing 1 × 107 hUCB-MSCs. The volume of regenerated bone was evaluated using micro-computed tomography at 4 and 8 weeks postoperation. At 4- and 8-week postoperation, the OVX group (5.0% ± 1.5%; 6.1% ± 0.7%) had a significantly lower regenerated bone volume than the Sham group (8.6% ± 1.3%; 12.0% ± 1.8%, P < 0.01), respectively. However, there was no significant difference between the OVX-MSCs and Sham groups. The OVX-MSCs group resulted in about 53% and 65% significantly higher new bone formation than the OVX group (7.7% ± 1.9%; 10.0% ± 2.9%, P < 0.05). hUCB-MSCs in bone defects may enhance bone regeneration in osteoporotic rat model similar to nonosteoporotic bone regeneration. hUCB-MSCs may be a promising alternative stem cell therapy for osteoporosis.

and Objectives:No-reflow is an important phenomenon for limiting the prognosis of patients following primary percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI). Coronary stenting is the current standard procedure for primary PCI in AMI. However, stenting is suspected to cause more microembolization, and no-reflow phenomenon. This study was performed to elucidate the risk factors for the no-reflow phenomenon following primary PCI with stenting, in patients with AMI.doi:10.4070/kcj.2004.34.4.368 fatcat:tqfe4zl43nfythoryywoicfalq

Results:29 patients (16%) showed no-reflow phenomenon (final TIMI flow grade less than 3). Conventional risk factors for coronary artery disease were not significant risk factors for the no-reflow phenomenon. In a univariate analysis, a high initial CK-MB level (>50 IU) (8.45% vs. 21.9%, p=0.04), low left ventricular ejection fraction (LV EF) (<50%) (19% vs. 5%, p=0.03) and long pre-dilatation balloon inflation time (>30 sec) (31% vs. 15%, p=0.04) were significant risk factors of the no-reflow phenomenon. A low LV EF and long pre-dilatation balloon inflation time were significant risk factors in a multivariate analysis. Conclusion:LV dysfunction at presentation and a long pre-dilatation balloon inflation time were independent risk factors for the no-reflow phenomenon following primary PCI with stenting for AMI. Preventive measures against the no-reflow phenomenon should be considered in patients with these risk factors.

Due to the lack of strong evidence on safety and efficacy of complementary and alternative medicine (CAM) approaches, the use of CAM in women during pregnancy could be hazardous for mother and fetus. Meanwhile, little is known regarding the patterns, the reasons and the factors affecting use of CAM among pregnant women in Iraq. Methods: A cross sectional survey design was used to carry out face-to-face interviews with 335 consecutive pregnant women. The questionnaire comprised of threedoi:10.1186/s12906-016-1167-0 pmid:27389024 pmcid:PMC4936269 fatcat:pfraa4kdmfbklcfwxv62nsibxa

Determinants of CAM use were assessed through the logistic regression analysis. Results: Three hundred thirty-five pregnant women completed the questionnaire. 56.7 % reported using at least one form of CAM modalities. In total, 24 different types of CAM were used; with herbal medicine (53.7 %) and multivitamins (36.3 %) the most commonly used modalities. From the logistic regression analysis, the variables positively associated with CAM use were: rural residence (odds ratio (OR) 2.0, p < 0.01), no occupation (OR 2.7, p < 0. 05), high income (OR 2.0, p < 0.05), perceived healthy status (OR 2.6, p < 0.05) and ever use of contraception (OR 2.0, p < 0.01). Only 0.5 % of CAM users disclosed their CAM use to physicians. Conclusions: The proportion of CAM users among pregnant women is relatively high and it is important to learn what types of CAM they use. However, disclosure of CAM use was extraordinarily low. Given the low rate of disclosure, it should be ensured that physicians establish good level of communication with pregnant women and have adequate knowledge of CAM.
Complementary and alternative medicine (CAM) use among infertile women is popular in many countries, including Korea. Previous research has repeatedly found more than half of infertile women surveyed use CAM therapies for fertility enhancement and overall well-being. However, there is currently little evidence to support this practice, and this raises the question of infertile women's experiences in the uptake of those modalities and sociodemographic and psychological factors associated withdoi:10.1186/s12906-019-2727-x pmid:31694617 pmcid:PMC6836421 fatcat:rwro2vzdzbfrtnj7v5voymdfsq

A cross-sectional study was conducted using data from 263 infertile women attending infertility specialty clinics in Seoul, Korea, in June 2012. The survey instrument included 47 questions on the use of CAM, demographic characteristics, health status, and infertility related factors such as duration and type of infertility, experience and satisfaction of conventional treatment, and self-perceived severity of infertility condition. Chi-square test and logistic regression were used for data analysis. Among 286 respondents (response rate, 95.3%), a total of 263 women were included in the final analysis. 63.5% of respondents used one or more types of CAM modalities during infertility treatment. The utilization of CAM was associated with employment status, duration of infertility treatment, and self-perceived severity of the disease. The most commonly used CAM modalities were multivitamin and herbal medicine, and differences in types of CAM modalities used were found between the group with a higher rating of self-perceived disease severity and the lower perceived severity group. High prevalence of CAM use among infertile women was observed in Korea. Our findings support that infertile women's own understanding of their illness and physical condition influences self-care behavior such as CAM use. This calls for an urgent need for further in-depth study of the clinical effects of popular CAM modalities among infertile women when used in conjunction with conventional treatment.
