The Layout of Plantar Loading with Centers of Gravity Balance and Rearfoot Posture in Daily Lives of Taiwanese College Elite Table Players
Authors: Chow Tong-Hsien , Lee Yu-Ling 
Published: June 2023

Abstract
Background
Table tennis is an asymmetric sport involving the powerful forward swing of the upper limbs depends on the solid support of the lower limbs. The foot drive really affects the weight balance and stroke accuracy even though the distance and momentum of the lower limb displacement are limited within a limited range. Given that previous research on table tennis has typically focused on the footwork and stroke performance of professional players, the study aimed to investigate the daily static and dynamic plantar load distribution as well as the centers of gravity balance and rearfoot posture among Taiwanese college elite table tennis players.
Methods
This is a cross-sectional study of 70 elite males and 77 same-gender amateur table tennis players aged 19 to 21 years from Taiwanese universities. The JC Mat optical plantar pressure analyzer was applied to determine the plantar load distribution along with arch index (AI) and centers of gravity balance. Assessment of rearfoot postural alignment was mainly used to contrast the performance of the centers of gravity balance.
Results
The static arch indices of both feet in the elite group were symmetrical and considered normal arches during their non-training and non-competition daily lives. Their static plantar loads were symmetrically concentrated on the bipedal lateral metatarsals as well as shifted to the medial and lateral heels and the lateral metatarsals during the walking midstance phase. Additionally, the plantar loads were mainly applied to the bipedal medial and lateral heels during the transitional changes between both states. Elite athletes had symmetrical and evenly distributed centers of gravity on both feet when standing statically, along with symmetrical rearfoot angles and neutral position of the subtalar joint even though they were statistically lower than those of the amateur athletes.
Conclusions
The daily static and dynamic foot patterns of Taiwanese college elite table tennis players were characterized by plantar load distribution on the lateral metatarsals and the entire calcaneus along with balanced centers of gravity and normal rearfoot posture. This foot and posture layout outlines the excellent athletic performance of the foot and ankle in professional athletes.

Abstract
Background
This study was carried out to investigate the antidiabetic activity of acarbose produced by Actinoplanes specie isolated from selected soils in streptozotocin induced diabetic rats. Acarbose produced by Actinoplanes utahensis was purified consecutively with dialysis, gel filtration and high-performance liquid chromatography, the test isolate can be exploited for large scale production of acarbose.
Results
Seven Actinoplanes species (Actinoplanes missouriensis, Actinoplanes utahensis, Actinoplanes aureus, Actinoplanes ramoplaninifer, Actinoplanes rhizophilus Actinoplanes auranticolour and Actinoplanes teichomyceticus.) isolated from termitary soils were screened based on the colonial morphology, microscopic, ability to assimilate carbon from various sugars. and their ability to produce acarbose. The isolates were able to produce acarbose, but Actinoplanes utahensis had a higher acarbose activity. The blood glucose level of the experimental rats reduced significantly from > 250mg/dL before treatment to ˂115mg/dL after treatment. The hematology results also showed a deviation in the red blood cells, white blood cells, lymphocyte counts and platelet counts. The red blood cell values reduced during the experiment, the white blood cells and Neutrophils increased while the lymphocytes reduced in the diabetic group during the experiment but there was a significant improvement to normalcy after treatment.
Conclusions
Actinoplanes utahensis has the highest ability to produce acarbose which can act as an antidiabetic drug for the treatment of type two diabetes.
A Data-driven Long-Short Term Load Forecasting with LSTM-RNN Networks
Authors: Waheed Waqar , Xu Qingshan 
Published: June 2023

Abstract
Operations and planning of power systems significantly rely on accurate load forecasts specifically after the
penetration of renewable energy resources. However, temporal relationships in load data are challenging to capture using
traditional statistical and machine learning methods. The application of recurrent neural networks, and more specifically
long short-term memory (LSTM) networks, to the modeling of sequence data with extensive temporal relationships has
yielded promising results. In this paper, we present a model for predicting future loads using a recurrent neural network
with long short-term memory.Effective demand response and distributed renewable energy sources can be better integrated
with this technology, which is crucial for the smart grid's stability and power demand estimation. However, it is
difficult to perform energy prediction with high accuracy because of influencing elements like climate, society, and
seasonality. We evaluate the accuracy of the model by using demand data collected from the German utility. The proposed
LSTM-RNN model exhibits significantly lower error rates in 1-24 hours and yearly load forecasts than conventional machine
learning techniques. In addition, the model is able to make accurate predictions despite receiving inadequate or noisy
inputs. Our findings imply that LSTM-RNN could be used in practice for effective load forecasting.

Published: June 2023

Abstract
The effect of Point like Global Monopole (PGM) topological defects on the energy eigenvalues of quantum systems embedded in Inverse Square Plus Yukawa (ISPY) potential under the influence of Aharonov-Bohm flux field has been studied here. ISPY potential is the superposition of inverse quadratic plus Yukawa potential. The radial part of the Schrödinger equation, a homogenous linear second-order differential equation, is solved under the framework of Asymptotic Iteration Method (AIM). Greene-Aldrich approximation scheme has been used to approximate the centrifugal barrier term which helps to find out the solutions of the Schrödinger equation for arbitrary l states. It is seen that, energy levels of a quantum system is significantly affected by the global effects of the point like global monopole, flux field and effective potential field.

Prevalence of multimorbidity and its association with socioeconomic status in Chinese older adults over time: Evidence from CHARLS 2011-2018
Authors: Liu Qin , Lu Jiehua 
Published: June 2023

Abstract
Background:
Previous studies on association between socioeconomic status and diseases mainly focused on a single disease. As people age, they are more likely to suffer from multiple coexisting chronic diseases, known as multimorbidity. This study aimed to explore the prevalence of multimorbidity and its association with socioeconomic status among older adults in China from 2011 to 2018.
Methods:
Four waves of cross-sectional data of people aged 60 and above were extracted from the China Health and Retirement Longitudinal Study (CHARLS) in 2011 to 2018 were used for secondary analysis. The prevalence of multimorbidity was calculated by descriptive analysis, while the association between socioeconomic status and multimorbidity was analyzed using the Logistic Regression Model and the Negative Binomial Regression Model.
Results:
The prevalence of multimorbidity among older adults in China demonstrated an increasing trend over the years, from 46.16% in 2011 to 57.50% in 2018. Significant association was detected between the socioeconomic status and multimorbidity of older adults, which was manifested as the higher the socioeconomic status, the higher the likelihood of being multimorbid. However, the influence of socioeconomic status on multimorbidity gradually disappearing and subsequently reappearing in a reversed direction over time.
Conclusions:
Multimorbidity has become a critical health problem that should not be ignored for older adults in China, and the relationship between socioeconomic status and multimorbidity may be changing over time, which needs to be further explored with data over a longer time span.

Published: June 2023

AbstractObjective:Due to the different surgical approaches for hyperplasia and adenoma in primary hyperparathyroidism, accurate preoperative diagnosis and identification are key factors affecting the surgery.18F-FCH PET/CT imaging is one of the effective methods for preoperative localization of hyperparathyroidism and can quantify parathyroid function by metabolic parameters. Therefore, the aim of this study was to analyze the diagnostic and differential value of18F-FCH PET/CT for hyperplasia and adenoma.Methods:This was a retrospective analysis of data related to 63 patients undergoing18F-FCH PET/CT at the First Hospital of Chongqing Medical University between December 2017 and December 2022. All procedures were completed, and postoperative pathological data were available for all patients. Comparison of laboratory parameters such as PTH and serum calcium between different patients to assess whether hyperplasia and adenoma can be distinguished based on laboratory indices, and analysis of PET/CT diagnosis and differences in metabolic parameters based on individual parathyroid lesions.The Mann–Whitney U test and binary logistic stepwise regression analysis were also used for univariate and multivariate analyses of information related to hyperplasia and adenomas, and the indicators found to be significant on multivariate analysis were used to determine cutoff values by receiver operating characteristic analysis.Results:A total of 75 parathyroid lesions were ultimately removed postoperatively in 63 patients, including 41 hyperplasia and 34 adenoma, and multiple lesions were present simultaneously in 9 patients. There were no significant differences in laboratory parameters between the different patient groups (P > 0.05). Based on the analysis of individual lesions, the sensitivity of PET/CT for the diagnosis of hyperplasia was 68.29% and that of adenoma was 97.06%. The sensitivity of PET/CT for adenoma was significantly higher than that of hyperplasia, and the size of the lesion may be the main factor affecting the sensitivity; in terms of differences in metabolic parameters, dual-phase SUVmax, MTV and TLG were significant in univariate analysis, and multivariate analysis showed the delayed TLG (cut-off value of 6.421) was a more reliable index for differentiating hyperplasia from adenoma (P=0.002).Conclusion:The diagnostic value of18F-FCH PET/CT for adenoma is higher than that of hyperplasia. Delayed TLG can differentiate hyperplasia from adenoma at the imaging level and help in the selection of clinical treatment options.

Abstract
Intention of our work is to develop cost-efficient, instant, sensitive and synergistic liquid-liquid extraction and spectrophotometric method for determination of silver(I) coupled with N'',N'''-bis[(E)-(4-fluorophenyl)methylidene] thiocarbonohydrazide i.e. bis-(4-fluoroPM)TCH and pyridine. The reagent (bis-(4-fluoroPM)TCH) and synergent pyridine instantly forms stable faint yellow colored complex with silver(I) at room temperature having composition 1:2:2 (M:L:Py) and quantitatively extracted into iso amyl acetate at pH 5.0. The extracted species exhibits absorption maximum at 375 nm against reagent blank. Experimental conditions were optimized and Beer’s law was observed in the concentration range of 1.0 to 7.0 µg mL− 1 of silver(I) and optimum concentration range obtained from Ringbom’s plot was found to be 2–6 µg mL− 1. The composition of silver(I)–bis-(4-fluoroPM)TCH–pyridine adduct was established by slope ratio, molar ratio & Jobs method. Molar absorptivity and Sandell’s sensitivity value of silver(I) chelate were 1.08 x104 lit/mol cm and 0.001µg/cm2 respectively. Selectivity of method was enhanced by use of suitable masking agents. Method has been successfully applied for determination of silver(I) in thin films, nano powders, hypo solutions, photographic wastes, X ray washings, pharmaceuticals, and synthetic mixtures. Accuracy of method was judged by using AAS which tested the validity of method.
Sucrose Recovery from Diluted Cane Molasses by Using Mass-transfer to The Third Liquid Layer at Contacting with Ethanol
Authors: OTANI Taketo , ANDO Hiroki , MIZUTA Kei , NII Susumu 
Published: June 2023

Abstract
A simple rate-based method for recovering sucrose from sugarcane molasses is proposed, focusing on the feasibility of continuous processing. When ethanol is gently poured onto diluted molasses, sucrose is transferred to ethanol along with water, resulting in the formation of a distinct third layer composing sucrose positioned between the ethanol and diluted molasses. Although the third liquid layer is metastable and dissipates when vigorously stirred, its sucrose concentration reaches a level suitable for sucrose crystal formation. Consequently, by continuously withdrawing the third layer while supplying ethanol to the diluted molasses, a semi-continuous operation for sucrose recovery from diluted molasses is achieved. To predict the concentration changes of sucrose over time within the third liquid layer, simple mass-transfer models based on diffusion and axial dispersion are employed. While the prediction yields limited success, it underscores the significance of mass-transfer from the liquid jet in the third layer and the role of mild mixing within the layer in facilitating its growth and interior mass-transfer. This study presents the first description of the effective utilization of the third liquid layer in solvent extraction and a method to control its formation and mass-transfer for sugar recovery from molasses.

Abstract
Many commercial pharmaceutical drugs and herbal remedies derived from medicinal plants rely on these metabolites. In this study, we investigated the influence of climatic factors and soil composition on the quantity, quality and efficiency of phenolic compounds in the typical species Aristolochia longa L. from three stations in eastern Algeria, each of which is located in a different bioclimatic stage.To characterize the chemical profile of crude methanolic extracts of three parts of Aristolochia longa L. from three different regions using liquid chromatography-mass spectrometry (LC-MS) analysis, also, their biological and pharmacological properties were evaluated: the antioxidant capacities (DPPH., ABTS−+, CUPRAC, FRAP, β-carotene-linoleic acid bleaching assays, ability to inhibit enzymes against acetylcholinesterase (AChE) and buthyrylcholinesterase (BChE)]. Secondary metabolites were extracted from leaves, stems and roots of Aristolochia longa L. The amount of polyphenols, flavonoids, flavones and flavonols were determined by colorimetric method. Various in vitro biochemical tests were performed to evaluate the antioxidant and free radical scavenging properties, the neuroprotective abilities of different extract were examined against the acetylcholinesterase and buthyrylcholinesterase enzymes. The components of the active extracts were identified by LC-MS and compared to reference substances. The antibacterial activity was evaluated using the agar disk diffusion method on reference strains of ATCC types. The results showed that Aristolochia longa L. extracts had strong antioxidant activity in all assays and a strong inhibitory effect against AChE and BChE enzymes, as well as antibacterial capacities against different strains. LC-MS analysis revealed the presence of eight phenolic compounds in methanolic extract of Aristolochia longa L. from leaves: apigenin, diosmin, quercetin, quercetine-3-glycoside, apigenin 7-O glycoside, rutin, neohesperidin and taxifolin. This work revealed significant differences in the yield sand chemical composition of leaves of Aristolochia longa L., collected from three locations in Algeria. Although the main components of the all extracts of leaves are common, however, their percentages are different. Furthermore, our study demonstrates a high variation in biological activity potentials according to parts of species and populations. This point out the importance of the geographic origin of the populations and the growing conditions which could significantly affect the composition and their biological activities.

Abstract
Background Alveolar echinococcosis is considered to be one of the most potentially lethal parasitic zoonotic diseases. However, the molecular mechanisms by which Echinococcus multilocularis interact with host are poorly understood and only limited treatments available. Due to the great advantages of cell culture systems for molecular research, numerous attempts have been made to establish primary cell cultures for Echinococcus multilocularis. In this study, we developed a simple, rapid and economic method, which allows Echinococcus multilocularis metacestodes tissue blocks to generate daughter vesicles without the presence of host feeder cells in regular medium.
Methods We performed anaerobic, hypoxic (1% O2), normoxic and semi-anaerobic (in sealed tubes) cultures for Echinococcus multilocularis metacestodes tissues to produce daughter vesicles. Then the daughter vesicles were cultured at three distinct oxygen consentrations (anaerobic, 1% O2, normoxic) to search optimal cultivation conditons. The daughter vesicle’s viability was assayed by carboxyfluorescein succinimidyl ester staining. These vesicles with good vigor were subsequently used for testing antiparasitic effect of albendazole, isolating primary cells and infecting animals.
Results After 4 weeks incubation, we found that Echinococcus multilocularis metacestodes tissues only cultured in sealed tubes produced daughter vesicles. And the daughter vesicles were observed remarkably enlarged under anaerobic conditions after 8 days of culture, while vesicles cultured under other two conditions showed a mild increase in volume. Our in vitro cultivated vesicles had good viability and can be used for testing of antiparasitic drugs, isolating primary cells and infecting animals.
Conclusions In the present work we established a simple, quick and economic method for in vitro generation vesicles from tissue blocks of Echinococcus multilocularis metacestodes in the absence of host feeder cells. Our in vitro cultivated vesicles with good viability are suitable for screening drugs for treatment of alveolar echinococcosis in vitro and in vivo.

Abstract
Background
Neuroendocrine breast carcinoma (NEBC) is a rare special histologic type of breast cancer. Information on the clinical outcomes of NEBC patients remains scant, with only some small sample studies documenting contradictory results.
Methods
We conducted a retrospective case‒control study of clinical characteristics and outcomes among patients with primary NEBC (pNEBC) versus invasive carcinoma of no special type (NST) between November 2004 and November 2017 in the Peking Union Medical College Hospital, Beijing. NST patients were strictly matched 1:4 during the same period based on TNM stage. Statistical comparisons were performed to determine the differences in survival between NST and pNEBC patients and to identify clinical factors that correlate with prognosis.
Results
A total of 121 participants affected by pNEBC were included in our analysis from November 2004 to November 2017. Elderly persons (>60 years of age) were more likely to have pNEBC than young persons (p=0.001). In addition, pNEBC patients had significantly higher odds of having tumors 2-5 cm (36.5%) and >5 cm (6.1%) in size than NST patients. Despite a significant difference in tumor size, the proportion of patients with lymphatic metastasis showed no difference between the two groups(p=0.021). In addition, the rate of patients with ER-negative tumors in the pNEBC group (4.2%) was significantly lower than that in the NST group (29.8%). Significant differences were noted in the PR-negative (13.3% versus 36.6%, P<0.001) and HER2-negative (90.5% versus 76.4%, P=0.001) expression statuses among these patients. Of 121 pNEBC patients, 11 (9.1%) experienced relapses during the follow-up period. We found that tumor size was an independent risk factor for relapse. For hormone receptors on tumor cells, ER-positive breast cancer patients had significantly lower odds of relapse than receptor-negative patients.
Conclusions
Our data demonstrate that there is no significant difference in mortality and relapse between the pNEBC and NST groups. The tumor size in the pNEBC group wassignificantly larger than that in the NST group. In addition, the absence of ER independently increased the relapse rate for breast carcinoma patients.
