Authors: Hara Yukinori , Tajiri Yasuhito , Kawano Kenichi , Hoshikawa Shinya , Kita Yusuke
Published: July 2020

Background: Amyloidosis treatment has advanced rapidly along with the discovery of drugs to prevent amyloid deposition. Therefore, it is vital to detect amyloidosis at an early stage. Wild-type transthyretin, which can cause carpal tunnel syndrome, may also cause finger tenosynovitis. However, the correlation between wild-type transthyretin amyloid and finger tenosynovitis is unclear. Here, we investigated pathological and clinical findings for 20 patients with finger tenosynovitis who underwent operation at our hospital to determine the frequency of transthyretin amyloid deposition in idiopathic finger tenosynovitis.

Methods: To check for the presence of amyloid deposition, all specimens (tendon synovium tissue or flexor tendon sheath) resected during the operation were stained by the direct fast scarlet method. Amyloid-positive specimens were evaluated by immunohistochemical staining using an anti-transthyretin antibody. Patient characteristics were evaluated with respect to amyloid presence.

Results: Thirteen (65%) of 20 finger tenosynovitis cases had amyloid deposition. Nine (69.2%) of the 13 amyloid-positive cases exhibited extensive transthyretin staining and were considered to have transthyretin amyloid. Amyloid deposition was more frequent in men. The mean number of fingers with tenosynovitis was significantly higher in amyloid-positive cases (3.8 fingers) than in amyloid-negative cases (2.0 fingers).

Conclusions: Men with multiple finger tenosynovitis tended to have transthyretin amyloid deposition. Our results support that multiple finger tenosynovitis may serve as an initial indication of evaluation for transthyretin amyloidosis.

Published: July 2020

Introduction. People with Parkinson’s disease (PD) have lower life satisfaction (LS) than healthy peers. No study has yet identified predictors of LS in people with PD. Such information would be valuable for health care and future interventions that aim to maintain or increase LS. Aim. To examine how LS evolved in people with PD over a 3-year period, as well as to identify predictive factors of LS. Methods. We used data from baseline assessments and a 3-year follow-up of 163 people with PD (baseline, mean age 68 years; median PD duration 8 years, 35% women). LS was assessed with item 1 of the Life Satisfaction Questionnaire (LiSat-11). Dichotomized LS data from the 3-year follow-up were used as the dependent variable in multivariable logistic regression analyses. In the first step, independent variables included baseline information on sex, education, general self-efficacy, motor symptoms, perceived walking difficulties, fall-related activity avoidance, and difficulties with/need help in activities of daily living. At the second step, depressive symptoms were added as an independent variable. Results. The proportion of those who reported being satisfied with their lives reduced from 63.2% at baseline to 49.7% 3 years later (p=0.003). When depressive symptoms were not included in the analysis, general self-efficacy (odds ratio, OR = 1.081; 95% CI = 1.019–1.147) and perceived walking difficulties (OR = 0.962; 95% CI = 0.929–0.997) were significant (p<0.05) predictors of LS 3 years later. With depressive symptoms included, the influence of walking difficulties diminished, and depressive symptoms (OR = 0.730; 95% CI = 0.607–0.877) and general self-efficacy (OR = 1.074; 95% CI = 1.010–1.142) were the only significant predictors of LS 3 years later. Conclusions. LS is reduced over a 3-year period. The study suggests that perceived walking difficulties, general self-efficacy, and depressive symptoms are important predictors of LS in people with PD.

Published: July 2020

Objective. To report a rare case of an acute attack of calcium pyrophosphate dihydrate (CPPD) deposition disease in a patient with lumbar spondylolytic spondylolisthesis, which demonstrated widespread lesion with neurological deficit. Methods. An 86-year-old woman presented with high fever and bilateral neurological deficit of the lower extremities. Results. CRP was elevated (20.9 mg/dl). Plain radiographs and computed tomography images showed bilateral L4 spondylolytic spondylolisthesis. Sagittal magnetic resonance (MR) images revealed effusion at the L3-4 interspinous space, and a gadolinium- (GD-) enhanced epidural mass was observed at the level of L4 vertebral body. Axial MR images showed an intra- or epidural lesion at L2-3. Moreover, epidural GD-enhanced masses compressed the dural sac in the shape of a cross at the L3-4 and L4-5 segments. The patient was suspected of having pyogenic arthritis of the lumbar spine in initial diagnosis. A total of 1.2 ml of fluid with a murky, pus-like synovial effusion was aspirated from the L3-4 interspinous space under the fluoroscopic image. Smear speculum of synovial fluid tested negative for bacteria and fungi; however, a number of crystals were seen. Based on the result of smear speculum, we suspected the pathology as crystal deposition disease. Based on polarized light microscopy, which revealed monocle or triclinic intracellular crystals with a positive birefringence, the patient was diagnosed with pseudogout of the lumbar spine. Nonsteroidal anti-inflammatory drugs (NSAIDs) were administered by intravenous drip injection for 3 days, and local and systemic inflammatory signs, as well as neurological deficits, dramatically improved. Conclusions. We encountered the rare case of an acute attack of pseudogout with the wide lesion in the lumbar spondylolytic spondylolisthesis. Multiple culture of the effusion provided a definitive diagnosis, which allowed for appropriate, minimally invasive treatment for 8 weeks of NSAID administration that provided the satisfactory recovery from the symptoms.

Published: July 2020

Let G be a graph of order n with vertices labeled as v1,v2,…,vn. Let di be the degree of the vertex vi, for i=1,2,…,n. The difference adjacency matrix of G is the square matrix of order n whose i,j entry is equal to di+dj−2−1/didj if the vertices vi and vj of G are adjacent or vivj∈EG and zero otherwise. Since this index is related to the degree of the vertices of the graph, our main tool will be an appropriate matrix, that is, a modification of the classical adjacency matrix involving the degrees of the vertices. In this paper, some properties of its characteristic polynomial are studied. We also investigate the difference energy of a graph. In addition, we establish some upper and lower bounds for this new energy of graph.

Published: July 2020

Background. The prevalence of peripheral vascular disease has led to the re-emergence of percutaneous axillary vascular access as a suitable alternative access site to femoral artery. We sought to investigate the efficacy and safety of manual hemostasis in the axillary artery. Methods. Data were collected from a prospective internal registry of patients who had a Maquet® (Rastatt, Germany) Mega 50 cc intra-aortic balloon pumps (IABP) placed in the axillary artery position. They were anticoagulated with weight-based intravenous heparin to maintain an activated partial thromboplastin time (aPTT) of 50–80 seconds. Anticoagulation was discontinued 2 hours prior to the device explantation. Manual compression was used to achieve the hemostasis of the axillary artery. Vascular and bleeding complications attributable to manual hemostasis were classified based on the Valve Academic Research Consortium-2 (VARC-2) and Bleeding Academic Research Consortium-2 (BARC-2) classifications, respectively. Results. 29 of 46 patients (63%) achieved axillary artery homeostasis via manual compression. The median duration of IABP implantation was 12 days (range 1–54 days). Median compression time was 20 minutes (range 5–60 minutes). There were no major vascular or bleeding complications as defined by the VARC-2 and BARC-2 criteria, respectively. Conclusion. Manual compression of the axillary artery appears to be an effective and safe method for achieving hemostasis. Large prospective randomized control trials may be needed to corroborate these findings.
Your Knock Is My Command: Binary Hand Gesture Recognition on Smartphone with Accelerometer
Authors: Zhang Huixiang , Xu Wenteng , Chen Chunlei , Bai Liang , Zhang Yonghui
Published: July 2020

Motion-based hand gesture is an important scheme to allow users to invoke commands on their smartphones in an eyes-free manner. However, the existing scheme is facing some problems. On the one hand, the expression ability of one single gesture is limited. As a result, a gesture set consisting of multiple gestures is typically adopted to represent different commands. Users must memorize all gestures in order to make interaction successfully. On the other hand, the design of gestures needs to be complicated to express diverse intensions. However, complex gestures are difficult to learn and remember. In addition, complex gestures set a high recognition barrier to smart APPs. This leads to an imbalance problem. Different gestures have different recognition accuracy levels, which may result in instability of recognition precision in practical applications. To address these problems, this paper proposes a novel scheme using binary motion gestures. Only two simple gestures are required to express bit “0” and “1,” and rich information can be expressed through the permutation and combination of the two binary gestures. Firstly, four kinds of candidate binary gestures are evaluated for eyes-free interactions. Then, an online signal cutting and merging algorithm is designed to split accelerometer signals sequence into multiple separate gesture signal segments. Next, five algorithms, including Dynamic Time Warping (DTW), Naive Bayes, Decision Tree, Support Vector Machine (SVM), and Bidirectional Long Short-Term Memory (BLSTM) Network, are adopted to recognize these segments of knock gestures. The BLSTM achieves the top performance in terms of both recognition accuracy and recognition imbalance. Finally, an Android application is developed to illustrate the usability of the proposed binary gestures. As binary gestures are much simpler than traditional hand gestures, they are more efficient and user-friendly. Our scheme eliminates the imbalance problem and achieves high recognition accuracy.
High-Precision Dynamics Characteristic Modeling Method Research considering the Influence Factors of Hydropneumatic Suspension
Authors: Wu Wenguang , Tang Hongliang , Zhang Sha , Hu Lin , Zhang Fanhao
Published: July 2020

In recent years, hydropneumatic suspension (HPS) has come into widespread use for improving the ride comfort and handling of mining dump trucks and off-road vehicles. Therefore, it is critical to improve the mathematical modeling accuracy to enhance the design and control efficiency and accuracy of HPS. This paper aims to propose a model for improving the modeling precision by considering the effect of different factors on HPS characteristics. A computational fluid dynamic (CFD) model of a HPS was developed, and the volume of fluid (VOF) method was used for the transient calculations in order to simulate the fluid dynamic characteristics and determine the damping and stiffness forces of HPS. The effect of temperature, oil viscosity, nitrogen dissolution rate, and suspension vibration speed on the nonlinear characteristics of HPS was investigated. A limited number of simulation sample points were designed based on the variation ranges of the above factors using the design of experiment (DOE) method. The corresponding damping and stiffness force of each sample point were calculated by CFD simulation. The obtained simulation data were utilized for the fitting of a Kriging model. The results demonstrated that the Kriging model can provide high accuracy, with a prediction error lower than 5%. The proposed modeling method of the HPS nonlinear characteristics is highly efficient, accurate, and faster than traditional methods.

Authors: Joo Sunghee , Kim Junghyun , Lee Yongwoo , Song Changho
Published: July 2020

Background. Spinal manipulation (SM) has been widely recognized and used with success in health care fields for spinal joint dysfunction and pain. SM is a procedure that involves small amplitude manipulative thrusts performed with speed. These forces are complex three‐dimensional (3‐D) forces delivered to create forces and moments at the joint of interest to cause joint movements. The aim of this study was to conduct a 3‐dimensional analysis of the magnitude and direction of the forces transmitted in 2 techniques of thoracic spinal manipulation (TSM). Materials/Methods. Thirty‐two healthy participants were recruited from the university community. The physical therapist performed TSM using anterior (A) to posterior (P) and P to A techniques once at each of T3, T7, and T12 spinal levels. The magnitude and direction of the forces transmitted during TSM were sensed by the force plates, and the camera system monitored vertebral motion by tracking motion markers. Results. There were no significant differences on the x‐axis while there were significant differences on the y‐axis between the measured spinal levels in the P to A technique. There were significant differences found at preload force maximum, preload force minimum, and peak force between T3 and T12 and between T7 and T12 and at peak base force between T7 and T12 on the z‐axis. In the A to P technique, there were significant differences in the change of force in measured spinal levels at different axes. Conclusion. These study findings can help therapists better understand the mechanism of TSM and enhance the clinical usefulness of TSM.

Published: July 2020

During hundreds of years of medication, it is believed that the steamed Panax notoginseng (SPN) can enrich and regulate the blood, replenish the body, and improve the health. The aim of this study was to optimize the steaming conditions of SPN which are related to the hematopoietic effect. In the study, network pharmacology and pharmacological experiments were used to predict and verify the potential hematopoietic active ingredients of SPN. Three variables including the steaming time (2‐10 h), steaming temperature (90‐130°C), and different producing areas of PN were investigated by using single‐factor analysis. Box‐Behnken design response surface methodology (BBD‐RSM) was performed to explore the optimized steaming conditions which are responsible for the hematopoietic effect of SPN. Furthermore, the hematopoietic effect of the optimized SPN was evaluated. Results demonstrated that ginsenoside Rd, Rh1, Rh4, Rk3, and 20(S)‐Rg3 can significantly increase blood routine parameters and expressions of hematopoietic factors in anemia mice. The total contents of the five ginsenosides were selected as evaluation indexes of the response surface method. We found that the PN from Wenshan steamed at 120°C for 5 h could significantly increase the levels of blood routine parameters and hematopoietic factor expression compared with the model group. The study not only provides data support for the determination of hematinic effect‐related markers for SPN but also gives a scientific reference for the processing of SPN which has a better hematopoietic effect. The underlying mechanisms require further research.

Published: July 2020

Background

The prevalence of ischemic heart disease (IHD) in women of child‐bearing age is rising. Data on pregnancies however are scarce. The objective is to describe the pregnancy outcomes in these women.

Methods and Results

The European Society of Cardiology‐EURObservational Research Programme ROPAC (Registry of Pregnancy and Cardiac Disease) is a prospective registry in which data on pregnancies in women with heart disease were collected from 138 centers in 53 countries. Pregnant women with preexistent and pregnancy‐onset IHD were included. Primary end point were maternal cardiac events. Secondary end points were obstetric and fetal complications. There were 117 women with IHD, of which 104 had preexisting IHD. Median age was 35.5 years and 17.1% of women were smoking. There was no maternal mortality, heart failure occurred in 5 pregnancies (4.8%). Of the 104 women with preexisting IHD, 11 women suffered from acute coronary syndrome during pregnancy. ST‐segment‒elevation myocardial infarction were more common than non‒ST‐segment‒elevation myocardial infarction, and atherosclerosis was the most common etiology. Women who had undergone revascularization before pregnancy did not have less events than women who had not. There were 13 women with pregnancy‐onset IHD, in whom non‒ST‐segment‒elevation myocardial infarction was the most common. Smoking during pregnancy was associated with acute coronary syndrome. Caesarean section was the primary mode of delivery (55.8% in preexisting IHD, 84.6% in pregnancy‐onset IHD) and there were high rates of preterm births (20.2% and 38.5%, respectively).

Conclusions

Women with IHD tolerate pregnancy relatively well, however there is a high rate of ischemic events and these women should therefore be considered moderate‐ to high‐risk. Ongoing cigarette smoking is associated with acute coronary syndrome during pregnancy.

Authors: Kamran Saadat , Singh Rajvir , Akhtar Naveed , George Pooja , Salam Abdul , Babu Blessy , Own Ahmed , Hamid Tahir , Perkins Jonathan D.
Published: July 2020

Background

Cardiac features diverge in Asians; however, it is not known how these differences relate to embolic stroke of unknown source (ESUS) in Southeast Asian and Eastern Mediterranean regions.

Methods and Results

A retrospective analysis of prospectively collected acute ischemic stroke data from 2014 to 2018 was performed. Stroke subtypes were noncardioembolic stroke (large‐vessel and small‐vessel disease; n=1348), cardioembolic stroke (n=532), and ESUS (n=656). Subtypes were compared by demographic, clinical, and echocardiographic factors. In multivariate logistic regression, patients with ESUS in comparison with noncardioembolic stroke were twice as likely to have left ventricular diastolic dysfunction (
P
=0.001), 3 times the odds of global hypokinesia (
P
=0.001), and >7 times the odds of left ventricular wall motion abnormalities (
P
=0.001). In the second model comparing ESUS with cardioembolic stroke, patients with ESUS were 3 times more likely to have left ventricular wall motion abnormalities (
P
=0.001) and 1.5 times more likely to have left ventricular diastolic dysfunction grade I (
P
=0.009), and 3 times more likely to have left ventricular diastolic dysfunction grades II and III (
P
=0.009), whereas age (
P
=0.001) and left atrial volume index (
P
=0.004) showed an inverse relation with ESUS. ESUS in patients ≥61 years old had higher levels of traditional risk factors such as coronary artery disease, but the coronary artery disease was not significantly different in ESUS age groups (
P
=0.80) despite higher left ventricular wall motion abnormalities (
P
=0.001).

Conclusions

Patients with ESUS and noncardioembolic stroke were younger than patients with cardioembolic stroke. While a third of the patients with ESUS >45 years old had coronary artery disease, it was unrecognized or underreported in the older ESUS age group (
≥
61 years old). In patients with ESUS from Southeast Asia and Eastern Mediterranean regions, left ventricular wall motion abnormalities and left ventricular diastolic dysfunction were related to ESUS.

Selective Preparation of Canvas as an ‘Artistic Device’ in David Hockney’s Early Paintings (1964–1972)
Authors: De Corte Hannah
Published: July 2020

In the mid-1960s and early 1970s, David Hockney opted for a particular application of primer in the ground layers of some of his paintings — that is, a partial or ‘selective’ type of preparation. By selectively preparing certain areas with one or more layers of (gesso) priming, Hockney introduced a slightly higher and white pictorial plane in selected areas while retaining the properties of raw canvas in others. In one of Hockney’s most discussed paintings, Portrait of an Artist (Pool with Two Figures), for instance, selective preparation divided the surface and set the stage from the ground up. This paper examines the impact of this highly original and hybrid formula on perception by the viewer, focusing on how the eye registers the change in properties of the paint layer. It outlines Hockney’s investigation of the primed/unprimed opposition through the use of selective preparation, and the variety of effects it allowed him to achieve in one canvas. From its anecdotal use in 1960s road trip paintings to its more pronounced use in pool paintings in which Hockney used unprimed canvas to convey the ‘wetness’ of water, selective preparation was a device for him to compellingly increase contrasts and tension. Far from producing mere formal effects or serving solely as citations (of stain paintings for instance), the perceived technical oddity produces meaning. From the ground layers up, it deeply influences the perception, and thus the interpretation of the discussed paintings.
The Jesuit Giambattista Tolomei (1653–1726): Cardinal and Philosopher
Authors: Pattenden Miles
Published: July 2020

This article sets out what is known of the life of Giambattista Tolomei (1653–1726), sometime rector of the Jesuit school in Ragusa (Dubrovnik), of the Collegio Romano, and the Collegio Germanico, cardinal of the Holy Roman Church, philosopher, theologian, bibliophile, and philologist. Tolomei’s life intersected a series of significant events in the church’s history and that of the Society of Jesus: on-going conflict with Jansenism, the Chinese Rites controversy, significant innovations in the Society’s intellectual curriculum, and its renewed incorporation within the upper echelons of the Roman Curia. Tolomei played a key part in all those developments, and his role in what transpired is explored here—placed in context to establish his significance to the Society’s history in the early eighteenth century and beyond.

Authors: Tian Jianxue , Zhang Jue , Tang Xiaofen , Dong Ting
Published: July 2020

To surmount the two-class imbalanced problem existing in the breast cancer diagnosis, a hybrid method of ROSE sampling approach with Boosted C5.0 ensemble classifier (R-Boosted C5.0) is proposed. ROSE as the sampling method is utilized to balance the class distribution. Boosted C5.0
is then used as the classifier. To serve this purpose, Wisconsin Breast Cancer Dataset (WBCD), Wisconsin Diagnosis Breast Cancer (WDBC) and three imbalanced datasets have been studied. Assessing by Matthews Correlation Coefficient (MCC), the performance of proposed method on WBCD and WDBC
datasets were 98.5% and 93.0%, respectively. The experimental results show that the proposed work outperforms in contrast with the rest of the classifiers. It can be used as a clinical decision support system to assist breast cancer prediction. In practice, the proposed methodology can be
further applied to class imbalanced data classification.

The paper aims to explore the diagnostic value of multi-parameter MRI in sub-stage of T3 rectal cancer. According to the results of clear pathological evaluation, 52 patients were divided into T3I and T3II groups according to the maximum mesorectum depth of tumor infiltration. The χ2
test was used to compare the differences of the overall morphology index, morphological index of the extramural strips, type of time-signal intensity curve (TIC), and the location index of DWI diffusion-limited distribution between the two groups. The independent sample t was used to
test and compare the differences in semi-quantitative parameters of DCE between the two lesion groups. The pathological results were used as the dependent variables, the indicators mentioned above with statistical differences were used as the independent variables, and a Logistic regression
model was established to construct joint parameters and evaluate its diagnostic efficacy. The differences in the circumferential diameter of lesions and morphological index of extramural strips (p < 0.01), and DWI diffusion restricted distribution index (p < 0.01) of the
two groups were statistically significant. The difference in the DCE semiquantitative parameter early enhancement ratio (EER) (p < 0.01) between the two groups. The maximum Youden index of a newly-constructed parameter diagnosis combination: circumferential diameter of lesions +
extramural strips + distribution locations of limited diffusion on DWI + EER was 0.73, the area under receiver operating characteristic curve(ROC) was 0.887 and the diagnostic sensitivity and specificity were 85.24% and 87.34%. By making full use of multi-parameter information, combined with
morphological index of extramural strips, circumferential diameter of lesions, EER and distribution locations of the diffusion-limited of DWI as evaluation indexes, it can provide a high diagnostic efficiency for the sub-stage of T3 rectal cancer.

Authors: Remya K. R. , Giriprasad M. N.
Published: July 2020

This paper proposes a classification technique using fuzzy inference system (FIS) for non-proliferative diabetic retinopathy (NPDR). The input variables to FIS are the extracted features from the pathologies of NPDR. Abnormalities like exudates and microaneuryms are segmented for feature
extraction. The pathological aspects of NPDR leads to fuzzy if-then rules that effectively handles the fuzziness present in some of the features. The role of FIS in NPDR classification replaces the training phase in learning based classification methods. The performance of the proposed fuzzy
approach is analyzed for stages of NPDR and diabetic retinopathy classification on various databases. The accuracy of 98.2% is observed for NPDR classification in Messidor database.

Authors: Ma Tian , Li Yurong
Published: July 2020

Because three-dimensional (3D) models of teeth are currently obtained via oral scanning, there are only the tooth crown and gingival surface part, lack of data on the roots of teeth, which is not conducive to the 3D reconstruction of teeth. In order to help doctors to carry out virtual
tooth correction, this paper studies the edge characteristics of the tooth crown model, removes the edge noise, which can better carry out the 3D reconstruction of teeth. Therefore, this paper proposes an improved method of tooth crown edge smoothing based on noise classification and fitting.
First, according to the characteristics of the tooth crown edge, the method of noise classification is proposed after fitting analysis. The noise can be divided into two types: the noise in the boundary line and the noise in the fitting curve. Then, the noise can be identified according to
the Gaussian curvature. Finally, the improved Laplacian smoothing and least squares fitting methods are used to remove the two types of noise, and the denoised tooth crown model is the output. The smoothing effect of the method is verified in terms of the noise removal rate, the patch filling
rate, and the patch deletion rate. Compared with the traditional Laplacian smoothig, the new method exhibited a noise removal rate increase of 86.0%, a probability of patch filling that approximately doubled, and a probability of patch deletion that basically remained the same. Compared with
the least squares fitting method, the new method exhibited a noise removal rate increase of 75.9%, a patch filling reduction of 22.61%, and a patch deletion reduction of 22.14%.

Published: July 2020

Wearable electrocardiogram (ECG) devices can provide real-time, long-term, non-invasive and comfortable ECG monitoring for premature beats (PB) assessment (typically presenting as premature ventricular contractions (PVC) and supraventricular premature beat (SPB)), which may foreshadow
stroke or sudden cardiac death. However, the poor quality, introduced by the dry electrode in wearable ECG monitoring system, leads to the inefficient recognition of the existing PB detection technologies. Although many methods can achieve high recognition rate on current widely-used open-access
clinical ECG databases, they still fail to work properly on dynamic ECG signals. This study presents an open-access ECG database comprises of 24-hour wearable ECG recordings. The database is used for the 3rd China Physiological Signal Challenge (CPSC 2020), where participants are expected
to recognize PVC and SPB from these recordings. All the approved algorithms are evaluated by scoring standards and regulations defined in terms of PVC detection and SPB detection, respectively.
Crystallization Behaviours of Poly(vinylidene fluoride) (PVDF) Nanocomposites with MoS2 Nanosheets with Different Surface Functional Groups
Authors: Gan Guihai , Wang Cheng , Chen Pengpeng , Liu Jichang
Published: July 2020

The crystallization behaviours of amorphous poly(vinylidene fluoride) (PVDF) nanocompositesmodified with two different kinds of molybdenum disulfide (MoS2) at different filler loadings were investigated in detail in this work. The crystallinity, melting temperature and crystallization
temperature of the PVDF/MoS2 nanocomposites were transformed from α-phase to β-phase with the addition of MoS2, MoS2-COOH and MoS2-NH2. During isothermal cold crystallization, the overall crystallization rate of
PVDF was slowed with increased MoS2 loading relative to that of neat PVDF. Moreover, the crystallization temperature of the PVDF nanocomposites increased with the addition of MoS2 despite the cooling rate during nonisothermal cold crystallization. DMA tests showed that
the storage modulus of PVDF was decreased with the addition of MoS2, while those of PVDF/MoS2-COOH and PVDF/MoS2-NH2 were enhanced to different degrees. The decomposition of the PVDF/MoS2 nanocomposites were also discussed. Relative to
neat PVDF, the thermal stability of PVDF was obviously improved with the addition of MoS2, MoS2-COOH and MoS2-NH2, which could be ascribed to the increased degree of crystallinity.

Published: July 2020

To study the effects of drug delivery using solid lipid nanoparticles in the treatment of acute noise exposure-induced cochlea damage. The solid lipid nanoparticles (SLNs) were used as carriers to effectively encapsulate the drug clozapine, improve drug stability in the carrier system,
and increase drug bioavailability in vivo. Solid lipid nanoparticles carrying clozapine were produced by ultrasonic technology. The clozapine solution or sulphate SLN was administered though intratympanic or intravenous injection on the first day of noise exposure Guinea pigs were exposed
to 110 dB sound pressure level (SPL) noise (2 h per day with center frequencies of 0.25–4.0 kHz for 4 days). After noise exposure, the guinea pigs were subjected to auditory brainstem response (ABR) threshold measurements. Reactive oxygen species (ROS) levels were detected in the cochlea
by electron spin resonance (ESR), and outer hair cell counts (OHCs) were obtained using silver nitrate (AgNO3). SLN particles carrying clozapine exhibited protective effects on the cochlea. The threshold shift and ROS production in treated animals, especially in animals treated
with clozapine SLN through intraperitoneal injection, were significantly lower than those in untreated animals.

Published: July 2020

Conventional thermal fluids with suspended nanoparticles, known as nanofluids, have been developed for heat transfer applications. Heat transfer loss could be reduced significantly if the thermophysical properties of the heat transfer fluid are improved, which to some extent, could
reduce the present global environmental challenges associated with energy utilization, such as climate change and global warming. In this work, the role of the concentration of sodium dodecyl-benzene sulfonate (SDBS) in the stability of Al2O3/bio-oil nanofluid is investigated
the zeta potential value, and its implications to the viscosity and thermal conductivity of the nanofluid are explored. The bio-oil based nanofluid is fixed using a two-step method in which the prepared base fluid is added with 13-nm alumina nanoparticles powder. Various weight fractions of
SDBS (0.1, 0.2, 0.4, 0.6, and 1.0 wt%) are used for both 0.1 and 0.2 wt% Al2O3 to investigate the significance of the stability of a nanofluid on its thermal conductivity and viscosity. Results indicate that a stable nanofluid has reduced viscosity and increased thermal
conductivity.

Published: July 2020

A microflower-like C/Bi2O2CO3/TiO2 nanocomposite was prepared via a two-step method. Scanning electron microscopy (SEM) showed the sample to have a layered petal-like microstructure consisting of many nanosheets with an average diameter of
2–5 μm, along with activated carbon (AC) or carbon nanotubes (CNTs) and TiO2 nanoparticles deposited on the surface. Compared with pure Bi2O2CO3, Bi2O2CO3/TiO2 photocatalyst loaded with
microflower-like carbon has a good degradation rate of methyl orange (MO) under visible light (0.019 min−1). The highest photodegradation efficiency of MO by AC or CNT-loaded Bi2O2CO3/TiO2 microflowers reached a maximum of 95% degradation
after 180 minutes of reaction. The results show that the photocatalytic reaction of the hole and the hydroxyl free radical groups were important for the process of the photocatalytic degradation, and the effect of the hole was slightly greater than that of the hydroxyl free radical. After
comparing the different photocatalysts, it showed that C and TiO2 could improve the photocatalytic activity of Bi2O2CO3-based photocatalysts.

Published: July 2020

Mechanical and degradation properties are crucial factors of guided tissue/bone regeneration (GTR/GBR) membranes. In this work, a series of fibrous membranes with different ratios of polycaprolactone (PCL) and gelatin (Gel) were prepared (PCL:Gel = 1:9 (P1G9), 3:7 (P3G7), 5:5 (P5G5),
7:3 (P7G3), and 9:1 (P9G1)) by electrospinning, and their physicochemical properties and In Vitro degradation behaviors were systematically investigated. Mechanical tests showed that tensile strength was enhanced with the presence of Gel, and the tensile strength of the P9G1 membrane
reached nearly three times that of the pure PCL membrane. The degradation rate of the composite membranes could be adjusted by controlling the ratio of PCL and Gel; the higher the Gel content was, the faster the degradation of the PCL/Gel membrane. The higher PCL content favored maintaining
the fibrous structure of the electrospun membranes. These findings will be beneficial for designing PCL/Gel composite materials for biomedical applications.
