Behavioral and hormonal effects of prenatal and maternal separation stresses in postpartum rats

ABSTRACT The aim of this study was to evaluate the hormone and anxiety levels of rat dams who were exposed to prenatal and maternal separation stress paradigms. Sprague–Dawley rat dams were divided into Prenatal Stress (PS), Maternal Separation (MS), Prenatal Stress and Maternal Separation (PS+MS), and Control (C) groups. All animals were subjected to the open field test on the 21st postnatal day. Same-day blood samples were obtained from the tail vein in order to examine corticotrophin-releasing hormone (CRH), estradiol, oxytocin, epinephrine, norepinephrine, prolactin, progesterone, brain-derived neurotrophic factor (BDNF), endorphin, and vasopressin levels of animals via enzyme-linked immunosorbent assay (ELISA). Oxytocin levels were the highest in the control group and the lowest in the MS group. CRH levels in the MS group were significantly higher than in the PS group (p < .05). Intriguingly, the BDNF level was the lowest in the control and highest in the MS group. While there was a strong correlation in the CRH, vasopressin, BDNF levels in the control group, various relations were observed in the stress groups. Stressed animals exhibited several behavioral anomalies including decreased fear responses such as freezing, enhanced duration, and increased number of entries into the central zone of the open field test apparatus. PS dams exhibited reductions in estradiol and norepinephrine levels relative to control or MS dams.
Comparison of outcomes of different osteotomy sites for hallux valgus: A systematic review and meta-analysis

Background Hallux valgus (HV) is a common foot deformity for which several corrective surgical procedures, with different osteotomy sites, have been reported. The purpose of the present study was to systematically review randomized (RCTs) or controlled (CCTs) clinical trials and perform meta-analysis on outcomes of different osteotomy sites of the first metatarsal. Methods An extensive literature search was conducted in PubMed and the Cochrane Library from January 1983 to July 2020. Studies were identified using the terms “hallux valgus” and “osteotomy”. We included RCTs or CCTs comparing different locations of osteotomy for the first metatarsal bone (distal vs. mid-shaft, distal vs. proximal, and mid-shaft vs. proximal). The surgical outcomes included postoperative hallux valgus angle (HVA), intermetatarsal angle (IMA), American Orthopaedic Foot and Ankle Society (AOFAS) score, pain visual analog scale (VAS) score, perioperative complications and recurrence of deformity. We enrolled 10 studies with a total of 793 feet in the qualitative synthesis following full-text screening. Results A majority of patients included in the enrolled trials showed mild to moderate deformity, with mean HVA <40°. Out of the 10 enrolled studies; six compared distal osteotomies with mid-shaft osteotomies and showed no significant differences in the surgical outcomes between the scarf and chevron groups; three RCTs compared distal osteotomies with proximal osteotomies with conflicting results, one RCT showed the superiority of proximal osteotomy while the other two RCTs showed equivalent outcomes; one study that compared between mid-shaft and proximal osteotomies showed equivalent outcomes between the groups. Conclusion For the management of mild to moderate HV deformity, we found no significant clinical and radiological differences between patients treated with scarf and chevron osteotomies. Further controlled trials comparing different sites of osteotomies for moderate to severe HV deformity are needed.
Artificial bee colony optimised controller for small-scale unmanned helicopter

ABSTRACT In this paper, an efficient approach to design and optimize a flight controller of a small-scale unmanned helicopter is proposed. Given the identified helicopter model, the Linear Quadratic Gaussian/Loop Transfer Recovery (LQG/LTR) robust control method is applied for trajectory tracking and attitude control of the helicopter with a two-loop hierarchical control architecture. Since the performance of the controller extremely depends on its weighting matrices, the Artificial Bee Colony (ABC) algorithm is introduced to automatically select the parameters of the matrices. Comparative studies between optimal algorithms are also carried out. A series of flight experiments and simulations are conducted to investigate the effectiveness and robustness of the proposed optimised controller.
CUSUM Charts for Monitoring the Characteristic Life of Censored Weibull Lifetimes

Companies routinely perform life tests on their products. Each of these life tests typically involves testing several units simultaneously with interest in the times to failure. Two aspects often associated with lifetime data that make the development of a control-charting procedure more demanding are that the data tend to be nonnormally distributed and censored. In this paper, one-sided lower and upper likelihood-ratio—based cumulative sum (CUSUM) control charting procedures are developed for Type I right-censored Weibull lifetime data to monitor changes in the scale parameter, also known as the characteristic life, for a fixed value of the Weibull shape parameter. Because a decrease in the characteristic life indicates a decrease in the mean lifetime of a product, a one-sided lower CUSUM chart is the main focus. We illustrate the development and implementation of the chart and evaluate its properties through a simulation study. The proposed CUSUM chart is compared with an exponentially weighted moving-average (EWMA) chart using the steady-state average run length (ARL) performance. The CUSUM chart is shown to perform better than the EWMA chart in detecting shifts for which it is designed.
Application of the Lugano Classification for Initial Evaluation, Staging, and Response Assessment of Hodgkin and Non-Hodgkin Lymphoma: The PRoLoG Consensus Initiative (Part 2—Technical)

Visual Abstract The aim of this initiative was to provide consensus recommendations from a consortium of academic and industry experts in the field of lymphoma and imaging for the consistent application of imaging assessment with the Lugano classification. Methods: Consensus was obtained through a series of meetings from July 2019 to October 2021 sponsored by the PINTaD (Pharma Imaging Network for Therapeutics and Diagnostics) as part of the ProLoG (PINTaD RespOnse criteria in Lymphoma wOrking Group) consensus initiative. Results: Consensus recommendations encompass all technical imaging aspects of the Lugano classification. Some technical considerations for PET/CT and diagnostic CT are clarified with regards to required imaging series and scan visits, as well as acquisition and reconstruction of PET images and influence of lesion size and background activity. Recommendations are given on the role of imaging and clinical reviewers as well as on training and monitoring. Finally, an example template of an imaging case report form is provided to support efficient collection of data with Lugano Classification. Conclusion: Consensus recommendations are made to comprehensively address technical and imaging areas of inconsistency and ambiguity in the classification encountered by end users. Such guidance should be used to support standardized acquisition and evaluation with the Lugano 2014.
Discussion of the gift-giving behavior in rural and urban area respectively: Empirical evidence in China

Sending gifts in specific festivals and events is a universal phenomenon. One major concern is the motivations behind the sizable and significant gift expenses. The purpose of this research is to compare the gift-giving motives between rural and urban households. Three hypotheses are formulated: baseline altruism hypothesis, social norm hypothesis, and continuation reciprocity hypothesis. All these hypotheses are then tested empirically base on the data from the 2010 China Family Panel Studies Survey (CFPS). The results show that urban households are more motivated by the social norm and baseline altruism, while rural households are more motivated by continuation reciprocity. To further assess the motivations for different income groups, the threshold regression model is applied. The estimates suggest distinct motives between the relatively higher income group and relatively lower income group. The results show that households in the relatively lower income group are not motivated by social norm motive at all. Instead, the continuation reciprocity motive seems to be dominating for them. These findings demonstrate that households in the urban and rural area with different income level react to gift-giving differently.
A non-transcriptional function of Yap regulates the DNA replication program in Xenopus laevis

In multicellular eukaryotic organisms, the initiation of DNA replication occurs asynchronously throughout S-phase according to a regulated replication timing program. Here, using Xenopus egg extracts, we showed that Yap (Yes-associated protein 1), a downstream effector of the Hippo signalling pathway, is required for the control of DNA replication dynamics. We found that Yap is recruited to chromatin at the start of DNA replication and identified Rif1, a major regulator of the DNA replication timing program, as a novel Yap binding protein. Furthermore, we show that either Yap or Rif1 depletion accelerates DNA replication dynamics by increasing the number of activated replication origins. In Xenopus embryos, using a Trim-Away approach during cleavage stages devoid of transcription, we found that either Yap or Rif1 depletion triggers an acceleration of cell divisions, suggesting a shorter S-phase by alterations of the replication program. Finally, our data show that Rif1 knockdown leads to defects in the partitioning of early versus late replication foci in retinal stem cells, as we previously showed for Yap. Altogether, our findings unveil a non-transcriptional role for Yap in regulating replication dynamics. We propose that Yap and Rif1 function as brakes to control the DNA replication program in early embryos and post-embryonic stem cells.
Surrogate-Assisted Multi-Objective Evolutionary Optimization With Pareto Front Model-Based Local Search Method

Some local search methods have been incorporated into surrogate-assisted multi-objective evolutionary algorithms to accelerate the search toward the real Pareto front (PF). In this article, a PF model-based local search method is proposed to accelerate the exploration and exploitation of the PF. It first builds a predicted PF model with current nondominated solutions. Then, some sparse points in the predicted PF are selected to guide the search directions of the local search in order to promote the search of promising sparse areas. The approximation degree of the predicted and real PFs will influence the speed of the local search, while extreme points can significantly influence the shape of the PF. To accelerate the search progress, the optima of surrogate models are utilized to promote the progress of finding extreme points. The proposed local search method is incorporated into a surrogate-assisted multi-objective evolutionary algorithm. The proposed surrogate-assisted multi-objective evolutionary algorithm with the proposed local search method is tested with Zitzler-Deb-Thiele (ZDT), Deb-Thiele-Laummans-Zitzler (DTLZ), and MAF instances. The experimental results demonstrated the efficiency of the proposed local search method and the superiority of the proposed algorithm.
Characterization of PRRSV in clinical samples and the corresponding cell culture isolates.

Isolation of porcine reproductive and respiratory syndrome virus (PRRSV) in cell culture is a primary means of obtaining virus isolates for autogenous vaccine production and other applications. However, it has not been well characterized whether cell culture isolate and the virus in clinical sample are equivalent. This study compared PRRSV ORF5 sequences from 1,024 clinical samples (995 PRRSV-2, 26 PRRSV-1, and 3 PRRSV-1 and PRRSV-2 PCR-positive) and their isolates in MARC-145 and/or ZMAC cells. For 3 PRRSV-1 and PRRSV-2 PCR-positive clinical samples, both PRRSV-1 and PRRSV-2 were isolated in ZMAC cells whereas either PRRSV-1 or PRRSV-2, but not both, was isolated in MARC-145 cells, with isolate sequences matching the respective viruses in clinical samples. Twenty-six PRRSV-1 and most of 995 PRRSV-2 PCR-positive clinical samples had matching viral ORF5 sequences with their cell culture isolates. However, 14 out of 995 PRRSV-2 cases (1.4%) had non-matching viral sequences between clinical samples and MARC-145 isolates although viral sequences from clinical samples and ZMAC isolates matched. This is concerning because, if the MARC-145 isolate is directly used for autogenous vaccine production without sequencing confirmation against the virus in the clinical sample, it is possible that the produced autogenous vaccine does not include the desired wild-type virus strain found on the farm and instead contains vaccine-like virus. Vaccine-specific PCR and next-generation sequencing performed on six selected cases indicated presence of ≥2 PRRSV-2 strains (mixed infection) in such clinical samples. In summary, PRRSV ORF5 sequences from clinical samples and cell culture isolates matched each other for majority of the cases. However, PRRSV sequences between clinical sample and MARC-145 cell culture isolate could occasionally be different when the clinical sample contains ≥2 PRRSV-2 strains. Characterizing PRRSV sequences from clinical samples and cell culture isolates should be conducted before using isolates for producing autogenous vaccines or other applications.

Association of physical therapy techniques can improve pain and urinary symptoms outcomes in women with bladder pain syndrome. A randomized controlled trial

ABSTRACT Purpose: to verify the effects of biofeedback (BF) and manual therapy (MT) associated with transcutaneous electrical nerve stimulation (TENS) or postural exercises (PE) in the treatment of bladder pain syndrome (BPS) in women regarding pain and urinary symptoms. Materials and Methods: a parallel-randomized controlled trial was conducted in BPS patients diagnosed according to NIH clinical criteria. Two specialized physiotherapists applied demographic and validated questionnaires of perineal and suprapubic pain (VAS), urinary symptoms and problems (ICSI and ICPI) and sexual function (FSFI) and a physical assessment was made to identify myofascial trigger points. Thirty-one women, mean age 51.8 ± 10.9 were randomized in three groups of treatment consisting of ten weekly sessions of BF and MT (Conventional group); BF, MT, and TENS (TENS group); and BF, MT, and PE (Postural group). Results: Postural group improved perineal and suprapubic pain after treatment (p<0.001 and p=0.001, respectively), and the suprapubic pain improvement remained persistent at 3 months of follow up (p=0.001). Postural group improved urinary symptoms and problems after treatment (p<0.001 and p=0.005, respectively) and during follow up (p<0.001 and p=0.001). Conclusions: Biofeedback and manual therapy associated with postural exercises showed a significant improvement in perineal and suprapubic pain and urinary symptoms after treatment and during follow-up. Both results suggest a possible role for the use of this physiotherapy technique to treat BPS patients. Longer follow-up and a larger number of patients are necessary to confirm these conclusions.
Modelling the temperature in joint friction of industrial manipulators

Summary In this paper, a new model for joint dynamic friction of industrial robot manipulators is presented. In particular, the effects of the temperature in the joints are considered. A polynomial-based model is proposed and the parameter estimation is performed without the need of a joint temperature sensor. The use of an observer is then proposed to compensate for the uncertainty in the initial estimation of the temperature value. A large experimental campaign show that the model, in spite of the simplifying assumptions made, is effective in estimating the joint temperature and therefore the friction torque during the robot operations, even for values of velocities that have not been previously employed.
Channel Function of Polycystin-2 in the Endoplasmic Reticulum Protects against Autosomal Dominant Polycystic Kidney Disease

Significance Statement Mutations of PKD2 encoding polycystin-2 cause autosomal dominant polycystic kidney disease (ADPKD). The prevailing hypothesis is that polycystin-2–mediated calcium ion influx in the primary cilia plays a central role in anticystogenesis. In this hypothesis, polycystin-2’s role in endoplasmic reticulum (ER) is to facilitate trafficking polycystin-1–polycystin-2 complexes to the cilia to inhibit cystogenesis. The trimeric intracellular cation (TRIC) channel TRIC-B is an ER-resident potassium ion channel that mediates potassium-calcium counterion exchange for inositol trisphosphate–mediated calcium ion release. Using TRIC-B as an experimental tool, the authors demonstrate that channel function of ER-localized polycystin-2 is important for anticystogenesis, presumably acting as a potassium channel to facilitate calcium ion release. The results help illuminate ADPKD pathogenesis and provide proof of principle for pharmacotherapy by TRIC-B activators. Visual Abstract Background Mutations of PKD2, which encodes polycystin-2, cause autosomal dominant polycystic kidney disease (ADPKD). The prevailing view is that defects in polycystin-2–mediated calcium ion influx in the primary cilia play a central role in the pathogenesis of cyst growth. However, polycystin-2 is predominantly expressed in the endoplasmic reticulum (ER) and more permeable to potassium ions than to calcium ions. Methods The trimeric intracellular cation (TRIC) channel TRIC-B is an ER-resident potassium channel that mediates potassium–calcium counterion exchange for inositol trisphosphate–mediated calcium ion release. Using TRIC-B as a tool, we examined the function of ER-localized polycystin-2 and its role in ADPKD pathogenesis in cultured cells, zebrafish, and mouse models. Results Agonist-induced ER calcium ion release was defective in cells lacking polycystin-2 and reversed by exogenous expression of TRIC-B. Vice versa, exogenous polycystin-2 reversed an ER calcium-release defect in cells lacking TRIC-B. In a zebrafish model, expression of wild-type but not nonfunctional TRIC-B suppressed polycystin-2–deficient phenotypes. Similarly, these phenotypes were suppressed by targeting the ROMK potassium channel (normally expressed on the cell surface) to the ER. In cultured cells and polycystin-2–deficient zebrafish phenotypes, polycystin-2 remained capable of reversing the ER calcium release defect even when it was not present in the cilia. Transgenic expression of Tric-b ameliorated cystogenesis in the kidneys of conditional Pkd2-inactivated mice, whereas Tric-b deletion enhanced cystogenesis in Pkd2-heterozygous kidneys. Conclusions Polycystin-2 in the ER appears to be critical for anticystogenesis and likely functions as a potassium ion channel to facilitate potassium–calcium counterion exchange for inositol trisphosphate–mediated calcium release. The results advance the understanding of ADPKD pathogenesis and provides proof of principle for pharmacotherapy by TRIC-B activators.
Deep learning model-assisted detection of kidney stones on computed tomography

ABSTRACT Introduction: The aim of this study was to investigate the success of a deep learning model in detecting kidney stones in different planes according to stone size on unenhanced computed tomography (CT) images. Materials and Methods: This retrospective study included 455 patients who underwent CT scanning for kidney stones between January 2016 and January 2020; of them, 405 were diagnosed with kidney stones and 50 were not. Patients with renal stones of 0–1 cm, 1–2 cm, and >2 cm in size were classified into groups 1, 2, and 3, respectively. Two radiologists reviewed 2,959 CT images of 455 patients in three planes. Subsequently, these CT images were evaluated using a deep learning model. The accuracy rate, sensitivity, specificity, and positive and negative predictive values of the deep learning model were determined. Results: The training group accuracy rates of the deep learning model were 98.2%, 99.1%, and 97.3% in the axial plane; 99.1%, 98.2%, and 97.3% in the coronal plane; and 98.2%, 98.2%, and 98.2% in the sagittal plane, respectively. The testing group accuracy rates of the deep learning model were 78%, 68% and 70% in the axial plane; 63%, 72%, and 64% in the coronal plane; and 85%, 89%, and 93% in the sagittal plane, respectively. Conclusions: The use of deep learning algorithms for the detection of kidney stones is reliable and effective. Additionally, these algorithms can reduce the reporting time and cost of CT-dependent urolithiasis detection, leading to early diagnosis and management.
Dietary Intakes and the Risk of Low Energy Availability in Male and Female Advanced and Elite Rock Climbers

Abstract Monedero, J, Duff, C, and Egan, B. Dietary intakes and the risk of low energy availability in male and female advanced and elite rock climbers. J Strength Cond Res 37(3): e8–e15, 2023—There is a culture among rock climbers of striving to maintain low body mass and percentage body fat to enhance performance. Diet practices based on this belief might lead to increased risk of low energy availability (LEA) or eating disorders (EDs). Twenty-five advanced or elite rock climbers (male, n = 14; female, n = 11) had body composition measured, completed 4-day food intake and physical activity diaries while wearing an accelerometer and heart rate monitor, and completed the Eating Attitudes Test (EAT)-26 and the Low Energy Availability in Females Questionnaire (LEAF-Q; n = 11 female subjects only). EAT-26 scores of 3.5 (1.8, 7.0) [median (IQR)] and 9.3 ± 6.4 (mean ± SD) for male and female subjects, respectively, indicated low risk of ED in this cohort, but 4 female subjects were at high risk of LEA according to LEAF-Q scores. Suboptimal (<45 kcal·kg·FFM−1·d−1) and LEA (<30 kcal·kg·FFM−1·d−1) were evident in 88 and 28%, respectively, of climbers. However, only the female climbers had energy intakes (1775 ± 351 kcal·d−1) significantly lower than their calculated energy requirements (2056 ± 254 kcal·d−1; p = 0.006). In all subjects, carbohydrate intakes were lower (male subjects: 3.8 ± 1.2 g·kg−1·d−1, p = 0.002; female subjects: 3.4 ± 0.7 g·kg−1·d−1, p < 0.001), and fat intakes were higher (male subjects: 1.6 ± 0.5 g·kg−1·d−1, p < 0.001; female subjects: 1.4 ± 0.4 g·kg−1·day−1, p < 0.001) than current sports nutrition recommendations, and inadequate intakes of calcium, magnesium, and vitamin D were observed. Female subjects specifically had lower than recommended intakes of protein and iron. These results show that advanced and elite rock climbers have a high prevalence of LEA and have a risk of having nutritional deficiencies as result of their diet.
