The purpose of this study was to investigate the relationship of the Borg scale score with leg-muscle oxygenated haemoglobin (OHb) and deoxygenated haemoglobin (HHb) levels on near infrared spectroscopy (NIRS) and the work rate, heart rate (HR), oxygen uptake (VO) and minute ventilation (VE) during supine cardiopulmonary exercise testing (CPET) in healthy adult men. We also investigated the relationships between the leg-muscle OHb and HHb levels and the work rate during supine CPET. Fifteen healthy male volunteers (mean age, 20.7 ± 0.6 years; mean height, 172.1 ± 5.7 cm; mean body weight, 61.7 ± 6.6 kg) participated in this study. The cardiopulmonary and NIRS parameters were assessed during each minute of supine CPET and at the end of the test. The Borg scale score significantly correlated with the work rate, HR, VO, and VE during supine CPET (Rs = 0.86-0.94, p < 0.05). Furthermore, the Borg scale score significantly correlated with the leg-muscle OHb and HHb levels during supine CPET (Rs = -0.6, and 0.8, respectively; p < 0.05). The leg-muscle OHb and HHb levels had significant correlations with the work rate (R = -0.62 and 0.8, respectively; p < 0.05). The Borg scale score may be used to determine the rating of perceived exertion, whole-body fatigue and local-muscle fatigue during supine exercise. Moreover, leg-muscle oxygenation is associated with the work rate in supine exercise, similar to that observed in upright exercise.

North China University of Science and Technology, Tangshan 063210, China.
Purpose: To investigate the effects of compression therapy combined with exercise for cancer patients (EXCAP) in patients with peripheral neuropathy caused by breast cancer chemotherapy.
Methods: Overall, 108 patients with peripheral neuropathy after chemotherapy for breast cancer were randomly divided into the control group (routine nursing), experimental group 1 (compression therapy), and experimental group 2 (compression therapy and EXCAP). The National Institute of Cancer Drug Toxicity Rating Scale and the Chemotherapy-Induced Peripheral Neuropathy Assessment Tool were assessed and compared between groups.

To further evaluate the effects of lymphocyte immunotherapy (LIT) for the treatment of RPL patients this study aimed to utilize this type of treatment in RPL patients with positive antinuclear antibodies (ANA) in comparison to ANA-negative RPL women. To this aim, 84 ANA-positive, 114 ANA negative, and 50 healthy pregnant women were recruited. To examine the frequency of cells before and after LIT, flowcytometry technique was employed.

Background: Cardiac surgery can lead to dysregulation with a pro-inflammatory state, resulting in adverse outcomes. Hemadsorption using the AN69 membrane (Oxiris membrane) has the properties to chelate inflammatory cytokines. We hypothesized that in patients at high risk of inflammation, the use of the Oxiris membrane could decrease inflammation, preserve endothelial function, and improve postoperative outcomes.

Pancreatic ductal adenocarcinoma (PDAC) is characterized by a dense extracellular matrix (ECM) exhibiting high stiffness and fast stress relaxation. In this work, gelatin-based viscoelastic hydrogels were developed to mimic the compositions, stiffness, and fast stress relaxation of PDAC tissues. The hydrogels were cross-linked by gelatin-norbornene-boronic acid (GelNB-BA), thiolated macromers, and a 1,2-diol-containing linear synthetic polymer PHD.

Phrynops geoffroanus has a wide distribution in South America, living in aquatic environments such as rivers, streams, and lakes, in natural and urban environments. In this work, the plastron formula and the diversity index associated with the allometric condition are established for the species. For the morphometric analyses, the following were calculated: standard error, class intervals, sample standard deviation, principal component analysis, and allometry.
