Dynamic profile of EVs in porcine oviductal fluid during the periovulatory period.

In mammals, around the time of ovulation, the hormonal profile dynamically changes in synchrony with reproductive events occurring in the oviduct, i.e. sperm arrival, fertilization and early embryo development. Extracellular vesicles (EVs) have been recently recognized as key components of the embryonic milieu, however, composition and function of oviductal EVs during this crucial period remains to be further explored. Therefore, we initially characterized EVs from porcine oviductal fluid specifically around the critical ovulation window: i.e. estrus (E), late estrus (LE, day of expected ovulation), post ovulation (PO) and additionally diestrus (D). Total EV numbers gradually rose from D to E, LE and PO (P < 0.05), which corresponded to the total EV protein amount (P < 0.05). Strikingly, the mean size of EVs in PO was significantly smaller than in E and LE groups, which also had a lesser proportion of small EVs (P < 0.05). The EV protein cargoes during the periovulatory period were further analyzed by mass spectrometry. Qualitative analysis detected 1118 common proteins, which are most enriched in the cellular component of EVs/exosomes. Hierarchical clustering indicated similar protein profile within the biological replicates, but large discrepancy among stages. Further quantitative analysis discovered 34 and 4 differentially expressed proteins in the comparison between E and PO, and the comparison between E and LE, respectively. The dynamic EV protein profile together with the quick adaption in EV size and quantity, suggests porcine oviductal EV secretion are under the hormonal influence during the estrus cycle.
The efficacy of intra-articular fentanyl supplementation for knee arthroscopy: A meta-analysis of randomized controlled studies

Introduction: The efficacy of intra-articular fentanyl supplementation for pain control after knee arthroscopy remains controversial. We conduct a systematic review and meta-analysis to explore the influence of intra-articular fentanyl supplementation for pain intensity after arthroscopic knee surgery. Methods: We searched PubMed, EMbase, Web of Science, EBSCO, and Cochrane Library databases through May 2019 for randomized controlled trials (RCTs) assessing the efficacy and safety of intra-articular fentanyl supplementation for arthroscopic knee surgery. This meta-analysis is performed using the random-effects model. Results: Four RCTs are included in the meta-analysis. Overall, compared with control group after knee arthroscopy, intra-articular fentanyl supplementation is associated with reduced pain scores at 1 h (standard mean difference (Std MD) = −3.50; 95% confidence interval (CI) = −5.68 to −1.32; p = 0.002), 2 h (Std MD = −4.73; 95% CI = −8.75 to −0.71; p = 0.02), and 8 h (Std MD = −5.02; 95% CI = −9.73 to −0.30; p = 0.04) but shows no substantial impact on pain scores at 4 h (Std MD = −3.94; 95% CI = −7.93 to 0.05; p = 0.05) or the supplementary analgesia (risk ratio = 0.56; 95% CI = 0.09–3.59; p = 0.54). Conclusions: Intra-articular fentanyl supplementation does benefit in pain control after knee arthroscopy.
City of Hope Quality of Life-Ostomy Questionnaire Validity and Reliability Assessment on a Croatian Sample

The aim of this study was to validate City of Hope Quality of Life-Ostomy Questionnaire (CoH-QoL-OQ) for assessing the quality of life (QoL) of ostomy patients in the Republic of Croatia. The CoH-QoL-OQ is widely used, but has not been translated or validated so it can be used in the Republic of Croatia. This cross-sectional study encompassed 302 surgery patients with colostomy, ileostomy, or urostomy (182 (60.3%) male and 120 (39.7%) female), whose average age is 59 (M = 59.3, SD = 15.8). The CoH-QoL-OQ was translated into Croatian language using accepted guidelines for translation. Patients were recruited in a telephone conversation, followed by mail containing the CoH-QoL–OQ delivered to the home addresses of the patients who agreed to participate. The collected data were analyzed to verify psychometric properties of the questionnaire on the Croatian sample. All subscales showed high level of internal consistency (Cronbach α = 0.73–0.89). The test-retest reliability indicated a very satisfactory temporal stability (r = 0.99). The Confirmatory Factor Analysis (CFA), showed that the originally established model was not adequate for the data (χ2 = 4237.88, p < 0.01, CFI = 0.540, NNFI = 0.481, RMSEA = 0.113). However, after modification that excluded problematic items, the data showed a better fit with the theoretical model (except for the LR chi-square test that remained statistically significant: χ2 = 1144.28, p < 0.01, CFI = 0.869, NNFI = 0.855 RMSEA = 0.077). We conclude that the CoH-QoL-OQ is a valid, reliable, and reducible instrument for measuring the health-related quality of life (HRQoL) among Croatian patients with ostomy in clinical research and clinical practice.
Multiplexed quantitative proteomic analysis of HEK293 provides insights of molecular changes associated to the cell density effect, transient transfection and virus-like particles production.

The production of virus-like particles (VLP) has gained importance over the last few years owing to the benefits they provide compared to conventional vaccines. The biopharmaceutical industry is currently searching for safer candidates based on VLPs for new and existing vaccines and implementing new methods of manufacturing, thus allowing a more sustainable, effective and species-specific production. Despite achieving lower yields compared to traditional platforms, the use of mammalian cells provides the right post-translational modifications, and consequently, the intensification of bioprocesses using mammalian cells platforms has become a matter of pressing concern. One of the methods subject of intensification is transient gene expression (TGE), which has been proven to be highly effective regarding VLP production for preclinical or even clinical trials. In this work, a multiplexed quantitative proteomic approach has been applied to study the molecular characteristics of HEK293 cell cultures when growing at cell densities higher than 4·106 cells/mL, and the effects related to cell transfection and to VLP production. The obtained results revealed a set of functional and metabolic profiles of HEK293 under these three different conditions that allowed the identification of physiological bottlenecks regarding VLP production. Regarding the cell density effect (CDE), molecular alterations in the cell biology were proposed helping explain the difficulty for the cells to be transfected at higher densities. In addition, an overall disruption of cellular homeostasis after transfection was observed based on altered biological processes and after identifying potential pathways liable to be optimized via metabolic engineering, different solutions are proposed to improve VLP production.
In-Season Session Training Load Relative to Match Load in Professional Ice Hockey

Supplemental Digital Content is Available in the Text. Abstract Allard, P, Martinez, R, Deguire, S, and Tremblay, J. In-season session training load relative to match load in professional ice hockey. J Strength Cond Res 36(2): 486–492, 2022—The aim of this study was to describe match load and intensity across player positions and match periods, the distribution of pregame training load and intensity over training days before a match, by player position, and the cumulative weekly training load over a season. Fifty professional ice hockey players, which at one time or another were part of the roster for the Laval Rocket during the 2017-18 season of the American Hockey League, participated in this study. External load was monitored in every training session and match over the season using portable inertial measurement units. Data are reported in absolute and relative values to a match. Defensemen have a lower intensity during matches than forwards (−1.70 OIL·min−1) while load is similar across position. The first period shows a higher relative load (+5.28% relative on-ice load [OIL]) while the third has a lower relative intensity (−2.91% OIL·min−1). Defensemen seem to train at a systematic higher relative intensity than wingers and centers (+8.34% relative OIL·min−1). Finally, the weekly training load remains relatively constant throughout the season (equivalent of 3.56 ± 1.69 matches played per week). Our results support the need for player monitoring in ice hockey using an individualized approach.
Changes in genetic parameters for fitness and growth traits in pigs under genomic selection

Abstract Genomic selection increases accuracy and decreases generation interval, speeding up genetic changes in the populations. However, intensive changes caused by selection can reduce the genetic variation and can strengthen undesirable genetic correlations. The purpose of this study was to investigate changes in genetic parameters for fitness traits related with prolificacy (FT1) and litter survival (FT2 and FT3), and for growth (GT1 and GT2) traits in pigs over time. The data set contained 21,269 (FT1), 23,246 (FT2), 23,246 (FT3), 150,492 (GT1), and 150,493 (GT2) phenotypic records obtained from 2009 to 2018. The pedigree file included 369,776 animals born between 2001 and 2018, of which 39,103 were genotyped. Genetic parameters were estimated with bivariate models (FT1-GT1, FT1-GT2, FT2-GT1, FT2-GT2, FT3-GT1, and FT3-GT2) using 3-yr sliding subsets. With a Bayesian implementation using the GIBBS3F90 program computations were performed as genomic analysis (GEN) or pedigree-based analysis (PED), that is, with or without genotypes, respectively. For GEN (PED), the changes in heritability from the first to the last year interval, that is, from 2009–2011 to 2015–2018 were 8.6 to 5.6 (7.9 to 8.8) for FT1, 7.8 to 7.2 (7.7 to 10.8) for FT2, 11.4 to 7.6 (10.1 to 7.5) for FT3, 35.1 to 16.5 (32.5 to 23.7) for GT1, and 35.9 to 16.5 (32.6 to 24.1) for GT2. Differences were also observed for genetic correlations as they changed from −0.31 to −0.58 (−0.28 to −0.73) for FT1-GT1, −0.32 to −0.50 (−0.29 to −0.74) for FT1-GT2, −0.27 to −0.45 (−0.30 to −0.65) for FT2-GT1, −0.28 to −0.45 (−0.32 to −0.66) for FT2-GT2, 0.14 to 0.17 (0.11 to 0.04) for FT3-GT1, and 0.14 to 0.18 (0.11 to 0.05) for FT3-GT2. Strong selection in pigs reduced heritabilities and emphasized the antagonistic genetic relationships between fitness and growth traits. With genotypes considered, heritability estimates were smaller and genetic correlations were greater than estimates with only pedigree and phenotypes. When selection is based on genomic information, genetic parameters estimated without this information can be biased because preselection is not accounted for by the model.
Risk of excessive sleepiness in sleep restriction therapy and cognitive behavioral therapy for insomnia: a randomized controlled trial.

STUDY OBJECTIVES Sleep restriction therapy (SRT) has been shown to be comparably effective relative to cognitive behavioral therapy for insomnia (CBT-I), but with lower requirements for patient contact. As such, SRT appears to be a viable alternate treatment for those who cannot complete a full course of CBT-I. However, it is unclear whether SRT-a treatment solely focusing on restricting time in bed-increases risk for sleepiness comparably to CBT-I. The current study tested objective sleepiness as an outcome in a randomized controlled trial comparing SRT, CBT-I, and attention control in a sample of postmenopausal women in whom insomnia was diagnosed according to criteria of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. METHODS Single-site, randomized controlled trial. A total of 150 postmenopausal women (56.44 ± 5.64 years) with perimenopausal or postmenopausal onset of Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition insomnia disorder were randomized to 3 treatment conditions: sleep education control (6 sessions); SRT (2 sessions with interim phone contact); and CBT-I (6 sessions). Blinded assessments were performed at pretreatment and posttreatment. Risk of excessive sleepiness was evaluated using a symmetry analysis of sleepiness measured through the Multiple Sleep Latency Test (MSLT). RESULTS The odds ratios (ORs) of being excessively sleepy versus nonsleepy were not different than 1.0 for both SRT (OR = 0.94, 95% confidence interval [0.13-6.96]) and CBT-I (OR = 0.62, 95% confidence interval [0.09-4.46]), indicating that the odds of becoming excessively sleepy following treatment was not different from the odds of being nonsleepy. This suggests that excessive sleepiness is not of unique concern following SRT relative to CBT-I or sleep education. CONCLUSIONS SRT appears to have a comparable risk profile for excessive sleepiness as CBT-I, and thus may be considered a safe alternative to CBT-I. Future research should characterize objective measures of excessive sleepiness immediately following sleep restriction.

Sgd1 is an MIF4G domain-containing cofactor of the RNA helicase Fal1 and associates with the 5’ domain of the 18S rRNA sequence

ABSTRACT Assembly of eukaryotic ribosomal subunits is a complex and dynamic process involving the action of more than 200 trans-acting assembly factors. Although recent cryo-electron microscopy structures have provided information on architecture of several pre-ribosomal particles and the binding sites of many AFs, the RNA and protein interactions of many other AFs not captured in these snapshots still remain elusive. RNA helicases are key regulators of structural rearrangements within pre-ribosomal complexes and here we have analysed the eIF4A-like RNA helicase Fal1 and its putative cofactor Sgd1. Our data show that these proteins interact directly via the MIF4G domain of Sgd1 and that the MIF4G domain of Sgd1 stimulates the catalytic activity of Fal1 in vitro. The catalytic activity of Fal1, and the interaction between Fal1 and Sgd1, are required for efficient pre-rRNA processing at the A0, A1 and A2 sites. Furthermore, Sgd1 co-purifies the early small subunit biogenesis factors Lcp5 and Rok1, suggesting that the Fal1-Sgd1 complex likely functions within the SSU processome. In vivo crosslinking data reveal that Sgd1 binds to helix H12 of the 18S rRNA sequence and we further demonstrate that this interaction is formed by the C-terminal region of the protein, which is essential for its function in ribosome biogenesis.
Prognostic Significance and Functional Relevance of Olfactomedin 4 in Early-Stage Hepatocellular Carcinoma

OBJECTIVES: Hepatocellular carcinoma (HCC) is a leading cancer-related cause of death. Unfortunately, recurrence is common even after curative treatment of early-stage patients, and no adjuvant treatment has yet been established. Aberrant expression of OLFM4 in human cancers has been reported; yet, its specific function during tumor development remains poorly understood, and its role in HCC is unknown. The purpose of this study is to examine the prognostic significance of OLFM4 and its functional relevance in determining recurrence in patients with early-stage HCC. METHODS: Immunohistochemical staining to assess expression, cellular distribution, and prognostic significance of OLFM4 was performed in a tissue microarray comprising 157 HCC tissues and matched nontumor tissues. In addition, expression of OLFM4-coding mRNA was assessed in a separate patients' cohort. The findings were validated by in vitro functional studies using siRNA directed against OLFM4 to assess its effect on cell motility and proliferation. RESULTS: The fraction of HCC samples exhibiting positive OLFM4 staining was higher in comparison with that observed in hepatocytes from matched nontumor tissue (61% vs 39%). However, cytoplasmic-only staining for OLFM4 was associated with vascular invasion (P = 0.048), MMP-7 expression (P = 0.002), and poorer survival (P = 0.008). A multivariate analysis confirmed the independent significance of OLFM4 in determining patients' outcome (5-year survival [58.3% vs 17.3%; HR: 2.135 {95% confidence interval: 1.135–4.015}; P = 0.019]). Correspondingly, inhibition of OLFM4 by siRNA modulated the expression of MMP-7 and E-cadherin, causing inhibition of cell proliferation, motility, and migration. DISCUSSION: To the best of our knowledge, we provide the first report on the prognostic significance of OLFM4 in HCC and identify its mechanistic role as crucial mediator of MMP family protein and E-Cadherin in determining cell invasion and metastasis formation.
LC-APCI(-)-MS determination of 1-chloro-2,4-dinitrobenzene, a model substrate for glutathione S-transferases.

1-Chloro-2,4-dinitrobenzene (CDNB) is widely used as a model substrate for measuring enzyme activity of glutathione S-transferases in toxicity studies and in studies focusing on the metabol-ic capacity of different test systems. To allow the quantification of CDNB at low, non-toxic concentra-tions, we developed a sensitive liquid chromatography-mass spectrometry (LC-MS) technique, which is based on electron capture ionization using atmospheric pressure chemical ionization (APCI) in negative ion mode. Gas phase reactions occurring under atmospheric pressure produce specific ions that allow direct CDNB quantification down to 17 ng/ml in water. Using the new technique, we were able to verify CDNB exposure concentrations applied in two typical toxicity studies with early life stages of the com-mon model organisms, zebrafish (Danio rerio) and a zebrafish embryonic cell line (Pac2).
Prospective associations between childhood neuropsychological profiles and adolescent eating disorders.

OBJECTIVE Cross-sectional associations between eating disorders (EDs) and deficits in neuropsychological functioning have been well documented; however, limited research has examined whether neuropsychological functioning is prospectively associated with EDs. The current study investigated prospective associations between neuropsychological functioning in childhood (ages 8 and 10) and ED behaviours and disorders in adolescence (at ages 14, 16, and 18 years) in a population-based sample. METHOD Participants (N = 4,803) were children enrolled in the Avon Longitudinal Study of Parents and Children, a population-based, prospective study of women and their children. Regression methods tested associations between facets of neuropsychological functioning (attention, working memory, and inhibition) and eating disorder symptoms and diagnoses. RESULTS Better scores on working memory tasks in childhood were associated with decreased risk of fasting but increased risk of excessive exercise during adolescence. Better inhibitory control was associated with decreased risk for disordered eating at age 14, and attentional difficulties were associated with increased risk for binge eating disorder during adolescence among boys but not girls. CONCLUSIONS Neuropsychological functioning may enhance risk for disordered eating behaviours in specific ways. Overall, effect sizes were small, and results did not support global associations between neuropsychological differences and ED risk in this sample.
Proteomic Signature of Nucleus Pulposus in Fetal Intervertebral Disc

Study Design Profiling proteins expressed in the nucleus pulposus of fetal intervertebral disc (IVD). Purpose To evaluate the molecular complexity of fetal IVDs not exposed to mechanical, traumatic, inflammatory, or infective insults to generate improved knowledge on disc homeostasis. Overview of Literature Low back pain is the most common musculoskeletal disorder, causing a significant reduction in the quality of life, and degenerative disc disorders mainly contribute to the increasing socioeconomic burden. Despite extensive research, the causative pathomechanisms behind degenerative disc disorders are poorly understood. Precise molecular studies on the intricate biological processes involved in maintaining normal disc homeostasis are needed. Methods IVDs of nine fetal specimens obtained from medical abortions were used to dissect out the annulus fibrosus and nucleus pulposus under sterile operating conditions. Dissected tissues were transferred to sterile Cryovials and snap frozen in liquid nitrogen before transporting to the research laboratory for protein extraction and further liquid chromatography tandem mass spectrometry (LC-MS/MS) analysis. Collected data were further analyzed using Gene Functional Classification Tool in DAVID and STRING databases. Results A total of 1,316 proteins were identified through LC-MS/MS analysis of nine fetal IVD tissues. Approximately 247 proteins present in at least four fetal discs were subjected to further bioinformatic analysis. The following 10 clusters of proteins were identified: collagens, ribosomal proteins, small leucine-rich proteins, matrilin and thrombospondin, annexins, protein disulfide isomerase family proteins and peroxiredoxins, tubulins, histones, hemoglobin, and prolyl 4-hydroxylase family proteins. Conclusions This study provides fundamental information on the proteome networks involved in the growth and development of healthy fetal discs in humans. Systematic cataloging of proteins involved in various structural and regulatory processes has been performed. Proteins expressed most abundantly (collagen type XIV alpha 1 chain, biglycan, matrilin 1, and thrombospondin 1) in their respective clusters also elucidate the possibility of utilizing these proteins for potential regenerative therapies.
The effects of acculturation on neuropsychological test performance: A systematic literature review

Abstract Objectives: This systematic literature review collated a series of empirical works on the relationship between acculturation and performances on neuropsychological tests commonly used in clinical settings. Acculturation is theorized to influence test performance, but the integration between these two concepts is weak in the theoretical literature. The objective of this review was to synthesize quantitative studies of acculturative effects on neuropsychological test performance to extract common findings. Method: A systematic search strategy was conducted using four databases to find studies using a validated acculturative scale and neuropsychological test(s) that were routinely used in clinical practice. Studies that used statistical methods which accounted or controlled for potential confounding variables were included. Results: Twenty-one studies were included in the review and a majority covered American minority groups, but three studies were conducted outside the US. Scales of acculturation were mostly unidimensional, and most studies adopted a flexible approach to testing. Seven studies did not produce any significant results between acculturation and cognitive test performance. Conclusion: Considerable of heterogeneity among the studies limited efforts to synthesize the data. However, tests of verbal and visuospatial delayed memory were consistently robust against the effects of acculturation. Acculturation however, influenced a variety of verbal and non-verbal tests, but findings were dependent on sample characteristics. There were insufficient data to confirm the clinical utility of acculturation measurement alongside testing. Recommendations for future research were discussed.
