BACKGROUND: Extracellular vesicles (EVs) are derived from internal cellular compartments, and have potential as a diagnostic and therapeutic tool in degenerative disease associated with aging. Mesenchymal stem cells (MSCs) have become a promising tool for functional EVs production. This study investigated the efficacy of EVs and its effect on differentiation capacity. METHODS: The characteristics of MSCs were evaluated by flow cytometry and stem cell differentiation analysis, and a production mode of functional EVs was scaled from MSCs. The concentration and size of EVs were quantitated by Nanoparticle Tracking Analysis (NTA). Western blot analysis was used to assess the protein expression of exosomespecific markers. The effects of MSC-derived EVs were assessed by chondrogenic and adipogenic differentiation analyses and histological observation. RESULTS: The range of the particle size of adipose-derived stem cells (ADSCs)- and Wharton’s jelly -MSCs-derived EVs were from 130 to 150 nm as measured by NTA, which showed positive expression of exosomal markers. The chondrogenic induction ability was weakened in the absence of EVs in vitro. Interestingly, after EV administration, type II collagen, a major component in the cartilage extracellular matrix, was upregulated compared to the EV-free condition. Moreover, EVs decreased the lipid accumulation rate during adipogenic induction. CONCLUSION: The results indicated that the production model could facilitate production of effective EVs and further demonstrated the role of MSC-derived EVs in cell differentiation. MSC-derived EVs could be successfully used in cell-free therapy to guide chondrogenic differentiation of ADSC for future clinical applications in cartilage regeneration.

Background and Purpose It is essential to develop a reliable predictive serum biomarker for Parkinson’s disease (PD). Te accumulation of alpha-synuclein (αSyn) and up-regulated expression of Rab35 participate in the etiology of PD. Te purpose of this investigation was to determine whether the combined assessment of serum αSyn and Rab35 is a useful predictive biomarker for PD. Methods Serum levels of αSyn or Rab35 were determined in serum samples from 59 sporadic PD patients, 19 progressive supranuclear palsy (PSP) patients, 20 multiple system atrophy (MSA) patients, and 60 normal controls (NC). Receiver operating characteristics (ROC) curves were calculated to determine the diagnostic accuracy of αSyn or/and Rab35 in discriminating PD patients from NC or atypical parkinsonian patients. Results The levels of αSyn and Rab35 were increased in PD patients. The serum level of Rab35 was positively correlated with that of αSyn in PD patients. Compared to analyzing αSyn or Rab35 alone, the combined analysis of αSyn and Rab35 produced a larger area under the ROC curve and performed better in discriminating PD patients from NC, MSA patients, or PSP patients. When age was dichotomized at 55, 60, 65, or 70 years, the combined assessment of αSyn and Rab35 for classifying PD was better in the group below the cutof age than in the group above the cutof age. Conclusions Combined assessment of serum αSyn and Rab35 is a better biomarker for discriminating PD patients from NC or atypical parkinsonian patients, and is a useful predictive biomarker for younger sporadic PD patients.

Noise and vibration on the bogie of a mass rapid train

Hsiu-Ying Hwang,Jia-Shiun Chen 대한기계학회 2011 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.25 No.10

This paper investigated a noise and vibration concern on a metro train while the train made turns. The study was conducted to identify the root causes of the vibration and noise through hardware experimental testing as well as dynamic computer simulation. The initial investigation indicated the noise came from the bogie of the train. It was between the slewing ring bearing and the friction sets. A lab test was established to duplicate the reported problem and to root out the causes. One-factor-at-a-time method was used to screen the main key factors. Under certain contact conditions, unsmooth turning would occur and cause the noise and vibration. Dynamic simulation was proposed in the study to predict the potential issue. A multibody dynamic model was built with train body, underbody, slewing ring bearing and friction set to simulate the train turning motion. The results showed unsmooth/discontinuous dynamic motions and torque oscillation behaviors. The stop-and-go and stick-and-slip motion led to the vibration. The analysis confirmed the unsmooth friction forces and adhesion could cause the noise and vibration. The computer simulation showed good correlation with the hardware testing. It demonstrated the computer dynamic simulation could be used to predict the potential friction induced vibration issues. In the study, a different substitute material was also investigated through the computer simulation. The results showed the vibration could be effectively reduced if ceramic compound friction material was used.

Yi-Ying Chang,Hsiu-Chou Liu,Chih-Feng Chen Asian Australasian Association of Animal Productio 2023 Animal Bioscience Vol.36 No.3

Objective: Few studies have genetically monitored chickens over time, and no research has been conducted on ducks. To ensure the sustainable management of key duck breeds, we used microsatellite markers to monitor Brown Tsaiya ducks over time genetically. Methods: The second, fourth, sixth to eighth generations of the Brown Tsaiya duck selected for feeding efficiency and control lines were included in this study to investigate the genetic variations, effective population size, population structure and the differentiation between populations over time with 11 microsatellite markers derived from Brown Tsaiya duck. Results: The results showed there were a slight decrease in the genetic variations and an increase in within-population inbreeding coefficient (F_IS) in both lines, but no consistent increase in F_IS was observed in each line. The effective population size in the second and eighth generations was 27.2 for the selected line and 23.9 for the control line. The change in allele richness showed a downward trend over time, and the selected line was slightly lower than the control line in each generation. The number of private alleles (N_p) in the selected line were higher than in the control line. Moderate differentiation was observed between the second and eighth generations in the selected line (F_ST = 0.0510) and the control line (F_ST = 0.0606). Overall, differentiation tended to increase with each generation, but genetic variation and structure did not change considerably after six generations in the two lines. Conclusion: This study provides a reference for poultry conservation and helps to implement cross-generation genetic monitoring and breeding plans in other duck breeds or lines to promote sustainable management.

Study Question: To evaluate the most ideal interval between blastocyst biopsy and vitrification in preimplantation genetic screening (PGS). Study Design, Size, Duration: This is a retrospective study and total 224 patients underwent the PGS from 2012 Dec. to 2015 Mar. All of patients underwent blastocyst vitrification after biopsy and 1~2 euploid blastocyst for transfer after warming. The primary outcome measures were the implantation and pregnancy rates per PGS-frozen embryo transfer cycle. Materials, Setting, Methods: The blastocyst grading including grade 4, 5 and 6 (according to Gardner grading system) on day 5 or day 6 were selected for trophectoderm biopsy. All blastocyst underwent vitrification immediately (interval: 0.5 hour) or 1 to 7 hours after biopsy. At the time of vitrification the grade of blastocyst expansion was also recorded. All patients were divided into two groups according to the grade of expanded (Group1: ≤1/2 expansion (n=41), Group2: ≥3/4 expansion (n=183)). Furthermore, combined two factors including the interval and morphology of blastocyst after biopsy, all patients were further divided into interval 1 (<3 hours and ≤1/2 expansion) and interval 2 (≥3 hours and ≥3/4 expansion). The morphologically best euploid blastocyst(s) (1~2 embryos) was/were selected first for transfer on the next cycle. Main Results: Assessment morphology of blastocyst after biopsy in different interval, at 0.5 hour after biopsy, 100% blastocyst was non-expansion; at 1 hour after biopsy, only 17% blastocyst was 3/4 expansion or all-expansion; at 3 hours after biopsy, 86% blastocyst was 3/4 expansion or all-expansion and after 5.5 hours, 100% blastocyst was all-expansion or hatching. All blastocysts were survival (100%, 359/359) after warming. The mean of embryo transfer number between all groups were no significantly difference. The implantation rate in Group2 (63.4%) was significantly higher than that in Group1 (46.9%, p=0.014). The pregnancy rates in Group4 (73.8%) was sig-nificantly higher than that in Group1 (51.2%, p=0.004). The implantation and pregnancy rates in the group of embryo ≥3/4 expansion combined with ≥3 hours after biopsy (63.6%, 178/280; 73.8%, 127/172) were significantly higher than that in the group of ≤1/2 expansion with <3 hour (45.6, 26/57; 50.0%, 18/36; p=0.0113 and p=0.0056, respectively). Conclusion: The most ideal interval between biopsy and vitrification was least 3 hours and ≥3/4 expansion of blastocyst after biopsy could improve the implantation and pregnancy rates for PGS.

Glycogen synthase kinase-3β (GSK-3β) is an important serine/threonine kinase that implicates in multiple cellular processes and links with the neurodegenerative diseases including Alzheimer’s disease (AD). In this study, structure-based virtual screening was performed to search database for compounds targeting GSK-3β from Enamine’s screening collection. Of the top-ranked compounds, 7 primary hits underwent a luminescent kinase assay and a cell assay using human neuroblastoma SH-SY5Y cells expressing Tau repeat domain (TauRD) with pro-aggregant mutation ΔK280. In the kinase assay for these 7 compounds, residual GSK-3β activities ranged from 36.1% to 90.0% were detected at the IC50 of SB-216763. In the cell assay, only compounds VB-030 and VB-037 reduced Tau aggregation in SH-SY5Y cells expressing ΔK280 TauRD-DsRed folding reporter. In SH-SY5Y cells expressing ΔK280 TauRD, neither VB-030 nor VB-037 increased expression of GSK-3α Ser21 or GSK-3β Ser9. Among extracellular signal-regulated kinase (ERK), AKT serine/threonine kinase 1 (AKT), mitogen-activated protein kinase 14 (P38) and mitogenactivated protein kinase 8 (JNK) which modulate Tau phosphorylation, VB-037 attenuated active phosphorylation of P38 Thr180/ Tyr182, whereas VB-030 had no effect on the phosphorylation status of ERK, AKT, P38 or JNK. However, both VB-030 and VB-037 reduced endogenous Tau phosphorylation at Ser202, Thr231, Ser396 and Ser404 in neuronally differentiated SH-SY5Y expressing ΔK280 TauRD. In addition, VB-030 and VB-037 further improved neuronal survival and/or neurite length and branch in mouse hippocampal primary culture under Tau cytotoxicity. Overall, through inhibiting GSK-3β kinase activity and/or p-P38 (Thr180/Tyr182), both compounds may serve as promising candidates to reduce Tau aggregation/cytotoxicity for AD treatment.
