Abstract
Rodríguez-Rosell, D, Yáñez-García, JM, Sánchez-Medina, L, Mora-Custodio, R, and González-Badillo, JJ. Relationship between velocity loss and repetitions in reserve in the bench press and back squat exercises. J Strength Cond Res 34(9): 2537–2547, 2020—This study aimed to compare the pattern of repetition velocity decline during a single set to failure performed against 4 relative loads in the bench press (BP) and full back squat (SQ) exercises. After an initial test to determine 1 repetition maximum (1RM) strength and load-velocity relationships, 20 men performed one set of repetitions to failure (MNR test) against loads of 50, 60, 70, and 80% 1RM in BP and SQ, on 8 random order sessions performed every 6–7 days. Velocity against the load that elicited a ∼1.00 m·s−1 (V1 m·s−1 load) was measured before and immediately after each MNR test, and it was considered a measure of acute muscle fatigue. The number of repetitions completed against each relative load showed high interindividual variability in both BP (coefficient of variation [CV]: 15–22%) and SQ (CV: 26–34%). Strong relationships were found between the relative loss of velocity in the set and the percentage of performed repetitions in both exercises (R
2 = 0.97 and 0.93 for BP and SQ, respectively). Equations to predict repetitions left in reserve from velocity loss are provided. For a given magnitude of velocity loss within the set (15–65%), the percentages of performed repetitions were lower for the BP compared with the SQ for all loads analyzed. Acute fatigue after each set to failure was found dependent on the magnitude of velocity loss (r = 0.97 and 0.99 for BP and SQ, respectively) but independent of the number of repetitions completed by each participant (p > 0.05) for both exercises. The percentage of velocity loss against the V1 m·s−1 load decreased as relative load increased, being greater for BP than SQ. These findings indicate that monitoring repetition velocity can be used to provide a very good estimate of the number (or percentage) of repetitions actually performed and those left in reserve in each exercise set, and thus to more objectively quantify the level of effort incurred during resistance training.

Bernat-Adell, MD, Collado-Boira, EJ, Moles-Julio, P, Panizo-González, N, Martínez-Navarro, I, Hernando-Fuster, B, and Hernando-Domingo, C. Recovery of inflammation, cardiac and muscle damage biomarkers after running a marathon. J Strength Cond Res 35(3): 626–632, 2021—Physical endurance sports conditions the increase of blood biomarkers responsible for the acute inflammatory response. The purpose of this study was to observe the impact of intense physical exercise on these biomarkers and detect their recovery pattern. This is an experimental study of repeated measures (pre-post marathon). The biomarkers lactate dehydrogenase (LDH), creatine kinase (CK), high-sensitivity troponin T (hs-TNT), and C-reactive protein (CRP) were analyzed in a total of 86 runners, 24 hours before the marathon, immediately after finishing the race and at 24, 48, 96, and 144 postrace hours. The comparative analyses were performed using the Friedman and Wilcoxon tests. The correlations between dependent and independent variables were analyzed using Spearman correlations. The data were processed through the IBM SPSS package, version 23. Significant value was p ≤ 0.05. The LDH increased and showed significant differences (p ≤ 0.001) for all times, compared with the initial LDH value, normalizing after 192 hours (p = 0.667) (effect size [ES], r = 0.807). The CK increased and showed significant differences (p ≤ 0.001) (ES, r = 0.975) up to 96 hours afterward, normalizing after 144 hours. The hs-TNT presented an increase and showed significant differences (p ≤ 0.001) between the pre-post race times, 24 and 48 hours, normalizing after 96 hours, although it showed a new significant value at 192 hours (p ≤ 0.001) (ES, r = 0.519). The CRP increased and showed significant differences (p ≤ 0.001) between the pre-post race times, at 24, 48, 96, 144, and 192 hours after race. The recovery after alterations produced by the marathon varies according to the biomarker. Blood levels of biomarkers decrease with longer race times. Greater energy expenditure increases the blood levels of LDH, CK, and hs-TNT.

Abstract
Cosic, M, Knezevic, OM, Nedeljkovic, A, Djuric, S, Zivkovic, MZ, and Garcia-Ramos, A. Effect of different types of loads on the force-velocity relationship obtained during the bench press throw exercise. J Strength Cond Res 35(9): 2401–2406, 2021—This study aimed (a) to evaluate the degree of linearity of the force-velocity (F-V) relationship across different types of loads, (b) to compare the magnitude of the F-V relationship parameters (maximum values of force [F
0], velocity [V
0], and power [Pmax]) between the different types of loads, and (c) to explore the concurrent validity of F
0 with traditional measures of maximal strength. The F-V relationships of 15 physically active men (age: 20.9 ± 2.0 years, bench press 1 repetition maximum relative to body mass: 1.20 ± 0.10 kg·kg−1) were determined during the bench press throw exercise using predominantly gravitational (W), inertial (I), and combined (W + I) loads. The bench press maximal isometric force (Fiso) and the 1RM were also assessed. The individual F-V relationships were highly linear regardless of the type of load considered (median r [range] = 0.98 [0.94, 1.00]). The W + I load provided the largest value of F
0 (972 ± 45 N; 6.0 and 14.6% higher than W and I, respectively), the I load the largest value of V
0 (2.99 ± 0.34 m·s−1; 40.4 and 20.1% higher than W and W + I, respectively), and the W load the lowest value of Pmax (501 ± 46 W; −22.7 and −17.1% lower than I and W + I, respectively). The F
0 obtained from the W load presented the highest association with Fiso and 1RM values (r > 0.90). The W + I load and the I load should be recommended to work closer to the F
0 and V
0 capacities, respectively. However, the W load should be recommended to assess maximal strength capacity through the value of F
0.
Intercluster Link Management for Quality of Service Development by Mitigating the Hidden Node Problem in Wireless Sensor Networks

Published: April 2019

Abstract
A hidden node problem occurs when two different cluster heads communicate with each other. The cluster head may always establish bidirectional connections to achieve another node in a different cluster from the first nongroup node. In the correspondence between two unique clusters, the occurrence of a hidden node cannot be recognized. The intercluster link management problem occurs in the system because of the hidden node. The intercluster grouping method is proposed to eliminate the hidden node problem when there is correspondence between two unique clusters. The cluster head initiates the proposed method by the grouping method. The Group Join Request (GJREQ) is sent by each cluster head to the other cluster, which is the nongroup member. The GJREQ is received by the nongroup member in the cluster, which promotes the request to other bidirectional nodes. This request is sent until it comes to the cluster head. The cluster head assigns a response in the affirmative and sends the information to the source node. The neighbor groups are points of interest that are used for sending and receiving the information between the clusters.
On the Use of Cox Regression for Statistical Analysis of Fatigue Life Results

Published: April 2019

AbstractThe presence of scatter is inherent to fatigue life studies of materials and structures; a wide variety of statistical tools exists for analysis. Among them, Cox (proportional hazards) regression is widely encountered in survival studies of medical sciences, but has not found frequent use in fatigue of materials. Of interest is the ability to treat scatter in both applied load and fatigue life as well as censored measurements of the latter. In the present work, this statistical approach is adapted for fatigue life studies. For ease of its application, it is numerically implemented as a Python module and provided for permissive free use. The module allows us to carry out Cox regression on raw fatigue life results. Survival estimates, which provide a relationship between the probability of failure and fatigue duration, can be additionally plotted with the module. Finally, the module allows us to plot probabilistic Wöhler (S-N) curves, which leads to a more accurate representation of scatter in fatigue life results.

Published: April 2019

Abstract
ASTM E3039-16, Standard Test Method for Determination of Crack-Tip-Opening Angle of Pipe Steels Using DWTT Specimens (superseded), is limited to drop-weight tear test (DWTT) specimens with thickness B in the range 6–20 mm. There is a trend in the pipeline industry toward heavier wall pipe in the range of 25-mm thickness; hence, there is a need to test thicker DWTT specimens for crack propagation resistance. To address this need, proportionally larger DWTT geometry is proposed to allow a larger steady-state region with the same analysis procedure as in ASTM E3039. To support the development of an E3039 Annex, tests of an X70 pipe steel with B = 26.8 mm were performed at quasistatic and intermediate rates. The critical crack-tip-opening angle (CTOAB/2) of 15.0° ± 1.7°, estimated according to ASTM E3039, was close to the CTOA of 14.7° measured at midthickness sections. The effect on CTOA of varying the loading rate between 5 × 10−5 m/s and 0.1 m/s was found to be negligible. Fracture surfaces of specimens interrupted during testing showed severe crack tunneling. Finite element analysis simulations of crack propagation using a damage-mechanics model were performed on standard and proportionally large DWTT specimens to derive and compare CTOAs. These results show that ASTM E3039 can be applied successfully with proportionally scaled specimens to measure CTOA for steels of thicknesses significantly larger than 20 mm.
Dramatically Amplified Thoracic Sympathetic Postganglionic Excitability and Integrative Capacity Revealed with Whole-Cell Patch-Clamp Recordings

Published: April 2019

AbstractThoracic paravertebral sympathetic postganglionic neurons (tSPNs) comprise the final integrative output of the distributed sympathetic nervous system controlling vascular and thermoregulatory systems. Considered a non-integrating relay, what little is known of tSPN intrinsic excitability has been determined by sharp microelectrodes with presumed impalement injury. We thus undertook the first electrophysiological characterization of tSPN cellular properties using whole-cell recordings and coupled results with a conductance-based model to explore the principles governing their excitability in adult mice of both sexes. Recorded membrane resistance and time constant values were an order of magnitude greater than values previously obtained, leading to a demonstrable capacity for synaptic integration in driving recruitment. Variation in membrane resistivity was the primary determinant controlling cell excitability with vastly lower currents required for tSPN recruitment. Unlike previous microelectrode recordings in mouse which observed inability to sustain firing, all tSPNs were capable of repetitive firing. Computational modeling demonstrated that observed differences are explained by introduction of a microelectrode impalement injury conductance. Overall, tSPNs largely linearly encoded injected current magnitudes over a broad frequency range. Thus, whole-cell recordings reveal tSPNs have more dramatically amplified excitability than previously thought, with greater intrinsic capacity for synaptic integration and with the ability for maintained firing to support sustained actions on vasomotor tone and thermoregulatory function. Rather than acting as a relay, these studies support a more responsive role and possible intrinsic capacity for tSPNs to drive sympathetic autonomic function.
Cyclin C Regulated Oxidative Stress Responsive Transcriptome in Mus musculus Embryonic Fibroblasts
Authors: Stieg David C , Chang Kai-Ti , Cooper Katrina F , Strich Randy 
Published: April 2019

Abstract
The transcriptional changes that occur in response to oxidative stress help direct the decision to maintain cell viability or enter a cell death pathway. Cyclin C-Cdk8 is a conserved kinase that associates with the RNA polymerase II Mediator complex that stimulates or represses transcription depending on the locus. In response to oxidative stress, cyclin C, but not Cdk8, displays partial translocation into the cytoplasm. These findings open the possibility that cyclin C relocalization is a regulatory mechanism governing oxidative stress-induced transcriptional changes. In the present study, the cyclin C-dependent transcriptome was determined and compared to transcriptional changes occurring in oxidatively stressed Mus musculus embryonic fibroblasts. We observed a similar number (∼2000) of genes up or downregulated in oxidatively stressed cells. Induced genes include cellular repair/survival factors while repressed loci were generally involved in proliferation or differentiation. Depleting cyclin C in unstressed cells produced an approximately equal number of genes (∼2400) that were repressed by, or whose transcription required, cyclin C. Consistent with the possibility that cyclin C nuclear release contributes to transcriptional remodeling in response to oxidative stress, we found that 37% cyclin C-dependent genes were downregulated following stress. Moreover, 20% of cyclin C- repressed genes were induced in response to stress. These findings are consistent with a model that cyclin C relocalization to the cytoplasm, and corresponding inactivation of Cdk8, represents a regulatory mechanism to repress and stimulate transcription of stress-responsive genes.
Quantifying the Power and Precision of QTL Analysis in Autopolyploids Under Bivalent and Multivalent Genetic Models

Published: April 2019

AbstractNew genotyping technologies, offering the possibility of high genetic resolution at low cost, have helped fuel a surge in interest in the genetic analysis of polyploid species. Nevertheless, autopolyploid species present extra challenges not encountered in diploids and allopolyploids, such as polysomic inheritance or double reduction. Here we investigate the power and precision of quantitative trait locus (QTL) analysis in outcrossing autopolyploids, comparing the results of a model that assumes random bivalent chromosomal pairing during meiosis to one that also allows for multivalents and double reduction. Through a series of simulation studies we found that marginal gains in QTL detection power are achieved using the double reduction model when multivalent pairing occurs. However, when exploring the effect of variable genotypic information across parental homologs, we found that both QTL detection power and precision require high and uniform genotypic information contents. This effect far outweighed considerations regarding bivalent or multivalent pairing (and double reduction) during meiosis. We propose that autopolyploid QTL studies be accompanied by both marker coverage information and per-homolog genotypic information coefficients (GIC). Application of these methods to an autotetraploid potato (Solanum tuberosum L.) mapping population confirmed our ability to locate and dissect QTL in highly heterozygous outcrossing autotetraploid populations.
Antydemoniczny charakter sakramentu pokuty i pojednania
Authors: Ficoń Marta 
Published: April 2019

Sakrament pokuty i pojednania to kontynuacja zbawczej mocy Tajemnicy Paschalnej Chrystusa jako wielkiego dzieła pojednania człowieka z Bogiem, z bliźnimi, z samym sobą i z całym światem stworzonym. Jednoczy w ten sposób to, co zostało rozdzielone przez ludzki grzech, popełniony za podszeptem diabła. Przebaczenie i łaska otrzymane od Boga w tym sakramencie pozwala pokonać rozłam i podziały, które są znakiem rozpoznawczym działania złego ducha oraz wziąć udział w zwycięstwie Chrystusa nad grzechem, śmiercią i Szatanem. Sama struktura spowiedzi pozwala odkryć antydemoniczny charakter tego sakramentu oraz prawdziwą wolność dzieci Bożych w Chrystusie.
Uwielbienie Boga w przekazie medialnym: mass media w świetle pierwszego papieskiego orędzia radiowego z 1931 roku
Authors: Misztal Wojciech 
Published: April 2019

Artykuł analizuje pierwsze papieskie orędzie radiowe wygłoszone 12 lutego 1931 roku przez Piusa XI. Szczególnie zwrócono uwagę na przedstawione tam rozumienie przekazu medialnego jako skierowanego do wszystkich, a więc posiadającego charakter nie tylko globalny, ale powszechny, także w tym znaczeniu, że papież zwraca się w nim również do Boga (w akcie uwielbienia i dziękczynienia). Jest to fakt, na który, jak się wydaje, niezbyt zwraca się uwagę. Omówiono kontekst powstania pierwszego papieskiego orędzia radiowego, obraz Boga ukazany przez papieża Piusa XI, w tym dobroczynne związki Boga z innymi odbiorcami przekazu. Pierwsze papieskie orędzie radiowe Piusa XI z 1931 roku zawiera wskazania, których uwzględnienie pomaga znacznie lepiej zrozumieć i coraz pełniej wykorzystać wielkie, nawet rosnące możliwości mediów współcześnie i w przyszłości.

Prawa mniejszości etnicznych w nauczaniu papieży. Zarys problemu prawnego
Authors: Butrymowicz Magdalena 
Published: April 2019

W historii walki ludności etnicznej Ameryki Północnej o poszanowanie praw Kościół katolicki był zawsze przestawiany jako ten podmiot, który najbardziej przyczynił się do naruszenia podstawowych praw tej ludności, w tym prawa do godności i samostanowienia. Niemal całkowicie pomija się postawę rządów państw kolonialnych czy nowo powstałego państwa kanadyjskiego, Stanów Zjednoczonych, a także innych wyznań chrześcijańskich, które wspierały politykę asymilacji, wysiedlenia i marginalizacji ludności etnicznej. W szeroko prowadzonej dyskusji w Kanadzie i Stanach Zjednoczonych głos Kościoła katolickiego, który stanął w obronie rdzennych mieszkańców kontynentu amerykańskiego, jest całkowicie zapomniany. Słowa kolejnych papieży upominających się o poszanowanie praw ludności etnicznej, odcinających się od polityki dehumanizacji są ignorowane, a wręcz negowane. Dlatego warto przypomnieć, że od samego początku Kościół katolicki poprzez swojego zwierzchnika, jakim jest papież, protestował przeciwko naruszeniu praw rdzennej ludności Ameryki Północnej i stanowczo odcinał się od wszelkich działań władzy państwowej zmierzającej do asymilacji tej ludności. W rzeczywistości to dzięki pracy misjonarzy, mających poparcie Stolicy Apostolskiej, zachowała się kultura, język czy tradycja ludności indiańskiej na tym kontynencie. Niniejszy artykuł przypomina zapomniany głos papieży w obronie praw ludności etnicznej Ameryki Północnej.

Abstract

Background
Lymphopenia occurs commonly in esophageal squamous cell carcinoma (ESCC) and may influence treatment outcomes. We aimed to examine its association with treatment response and tumor progression in patients with locally advanced ESCC treated with concurrent chemoradiotherapy (CCRT).

Materials and Methods
A total of 286 patients with stage II–IVa ESCC treated with CCRT between 2015 and 2017 were analyzed. Total lymphocyte counts were assessed at baseline, weekly, and 4 weeks after CCRT. Pretreatment lymphopenia was defined as total lymphocyte count &lt;1,000 cells per mm3 at diagnosis, and treatment-related lymphopenia was defined as total lymphocyte count &lt;200 cells per mm3 with 6 weeks after starting CCRT. Univariate and multivariate logistic regression methods were used to analyze factors associated treatment-related lymphopenia and treatment response.

Results
Lymphopenia was observed in 44 patients (15.4%) at initial diagnosis. Pretreatment lymphopenia was significantly associated with greater tumor length, worse T status, body mass index ≤18.5 kg/m2, and weight loss ≥3 kg in the previous 3 months. Six weeks after starting CCRT, 89 patients (31%) developed treatment-related lymphopenia. Tumor progression and cancer-related death were more frequently observed in treatment-related lymphopenia group than those without (76.4% vs. 52.8% and 58.4% vs. 39.6%). A complete response (CR) was achieved in 62 patients (21.7%). In multivariate analysis, treatment-related lymphopenia was significantly associated with lack of clinical CR, and older age, lower tumor location, greater tumor length, and larger planning target volume were independent predictors of treatment-related lymphopenia.

Conclusion
Treatment-related lymphopenia during CCRT is an independent predictor for poor treatment response in ESCC.
