Furthermore, the average friction coefficient of a composite containing 4 wt.% MoS2 is 16.14% lower, and the volume wear rate is 92.84% lower than that of pure EP.Olive tree with its main final product, olive oil, is an important element of Mediterranean history, considered the emblematic fruit of a civilization. Despite its wide diffusion and economic and cultural importance, its evolutionary and phylogenetic history is still difficult to clarify. As part of the Mediterranean basin, Algeria was indicated as a secondary diversification center. However, genetic characterization studies from Maghreb area, are currently underrepresented. In this context, we characterized 119 endemic Algerian accessions by using 12 microsatellite markers with the main goal to evaluate the genetic diversity and population structure. In order to provide new insights about the history of olive diversification events in the Central-Western Mediterranean basin, we included and analyzed a sample of 103 Italian accessions from Sicily and, a set of molecular profiles of cultivars from the Central-Western Mediterranean area. The phylogenetic investigation let us to evaluate genetic relationships among Central-Mediterranean basin olive germplasm, highlight new synonymy cases to support the importance of vegetative propagation in the cultivated olive diffusion and consolidate the hypothesis of more recent admixture events occurrence. This work provided new information about Algerian germplasm biodiversity and contributed to clarify olive diversification process.Depression and anxiety are major mental health problems in all parts of the world. These illnesses are associated with a number of risk factors, including oxidative stress. Psychotropic drugs of a chemical nature have demonstrated several side effects that elevated the impact of those illnesses. Faced with this situation, natural products appear to be a promising alternative. The aim of this study was to evaluate the anxiolytic and antidepressant effects of the Petroselinum sativum polyphenols in vivo, as well as its correlated antioxidant properties in vitro. Anxiolytic activity of the extract (50 and 100 mg/kg) was evaluated using the open field and the light-dark chamber tests, while the antidepressant activity was evaluated using the forced swimming test. The antioxidant activity of the extract was evaluated by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical test and the FRAP (iron-reducing capacity) test. The phenolic extract showed very powerful anxiolytic and antidepressant-like effects, especially at a dose of 100 mg/kg, decreasing the depressive behavior in mice (decreased immobility time) and also the anxiolytic behavior (tendency for discovery in the center and illuminated areas) better even than those of paroxetine and bromazepam (classic drugs) concomitant with those results the extract also showed an important antioxidant capacity. These preliminary results suggest that Petroselinum sativum exhibits anxiolytic and antidepressant potential for use as a complement or independent phytomedicine to treat depression and anxiety.Patients treated for gynaecological cancer (GC) generally experience impaired sexual function. Research on their sexual life experiences and perceptions on the sexuality care they receive is warranted. This study aimed to examine the perceptions of Chinese patients treated for GC regarding the effects of cancer treatment on their sexual function and femininity, their relationships with their partners, and the adequacy of the sexual information received from healthcare professionals during treatment. Individual, semi-structured interviews were conducted with 21 Chinese patients treated for GC, collecting data on their perceptions regarding the effects of cancer treatment on their sexual lives, femininity, and relationships with partners; and their views about the quality of sexuality care received. Data were analysed using content analysis. Participants experienced impaired sexual function, reduced sex drive, and expressed dissatisfaction with their sex lives. They perceived a loss of femininity and poor body image. They desired more information about how to address sexual problems and opted to receive this information from female healthcare professionals in individual counselling sessions during which the professionals could initiate such discussions. Overall, Chinese patients treated for GC have concerns about multiple sexual issues and a strong desire for information about strategies to address these issues. Nurse-led interventions should be implemented via a shared care approach to enhance patients' awareness about managing their sexual and psychological symptoms.The aim of this study was to investigate the effect of acute Ramadan fasting (RF) on the muscle function and buffering system. Twelve male athletes with 8 years of professional sports experience (age, 23.2 ± 1.3 years, body mass index 24.2 ± 2.2 kg/m2) participated in this study. The subjects were tested twice, 3 weeks after the beginning of RF and 2 weeks after the end RF. Muscle function, buffering capacity, and rating of perceived exertion (RPE) were measured during and after RF by using the Biodex isokinetic machine, blood gas analyzer, and RPE 6-20 Borg scale, respectively. Venous blood samples for pH and bicarbonate (HCO3-) were measured during and after RF by using the Biodex isokinetic machine, blood gas analyzer, and RPE 6-20 Borg scale, respectively. Venous blood samples for pH and bicarbonate (HCO3-) were taken immediately after 25 repetitions of isokinetic knee flexion and extension. Measures taken during isokinetic knee extension during RF were significantly lower than those after RF in extension peak torque (t = -4.72, p = 0.002), flexion peak torque (t = -3.80, p = 0.007), extension total work (t = -3.05, p = 0.019), extension average power (t = -4.20, p = 0.004), flexion average power (t = -3.37, p = 0.012), blood HCO3- (t = -2.02, p = 0.041), and RPE (Z = -1.69, p = 0.048). No influence of RF was found on the blood pH (t = 0.752, p = 0.476). RF has adverse effects on muscle function and buffering capacity in athletes. It seems that a low-carbohydrate substrate during RF impairs muscle performance and reduces the buffering capacity of the blood, leading to fatigue in athletes.The degradation and mechanical properties of potential polymeric materials used for green manufacturing are significant determinants. In this study, cellulose nanofibre was prepared from Schizostachyum brachycladum bamboo and used as reinforcement in the PLA/chitosan matrix using melt extrusion and compression moulding method. The cellulose nanofibre(CNF) was isolated using supercritical carbon dioxide and high-pressure homogenisation. The isolated CNF was characterised with transmission electron microscopy (TEM), FT-IR, zeta potential and particle size analysis. The mechanical, physical, and degradation properties of the resulting biocomposite were studied with moisture content, density, thickness swelling, tensile, flexural, scanning electron microscopy, thermogravimetry, and biodegradability analysis. The TEM, FT-IR, and particle size results showed successful isolation of cellulose nanofibre using this method. The result showed that the physical, mechanical, and degradation properties of PLA/chitosan/CNF biocomposite were significantly enhanced with cellulose nanofibre. The density, thickness swelling, and moisture content increased with the addition of CNF. Also, tensile strength and modulus; flexural strength and modulus increased; while the elongation reduced. The carbon residue from the thermal degradation and the glass transition temperature of the PLA/chitosan/CNF biocomposite was observed to increase with the addition of CNF. The result showed that the biocomposite has potential for green and sustainable industrial application.Myrosinase is a plant defence enzyme catalysing the hydrolysis of glucosinolates, a group of plant secondary metabolites, to a range of volatile compounds. One of the products, isothiocyanates, proved to have neuroprotective and chemo-preventive properties, making myrosinase a pharmaceutically interesting enzyme. In this work, extracellular expression of TGG1 myrosinase from Arabidopsis thaliana in the Pichia pastoris KM71H (MutS) strain was upscaled to a 3 L laboratory fermenter for the first time. Fermentation conditions (temperature and pH) were optimised, which resulted in a threefold increase in myrosinase productivity compared to unoptimised fermentation conditions. check details Dry cell weight increased 1.5-fold, reaching 100.5 g/L without additional glycerol feeding. Overall, a specific productivity of 4.1 U/Lmedium/h was achieved, which was 102.5-fold higher compared to flask cultivations.The COVID-19 pandemic has had a significant impact on the operation of medical facilities. In this period, they have seen increased absence of medical staff from work, a decrease in the number of hospitalizations and in the value of healthcare services provided. We assess the impact of this pandemic on the operation of a non-COVID-19 orthopedic and rehabilitation hospital using International Classification of Functioning, Disability and Health (ICF) categories. The authors analyzed these parameters in relation to the operation of a non-COVID-19 orthopedic, rehabilitation and rheumatological hospital in Q1 2020 compared to Q1 2019. For the analysis, the categories and qualifiers of the ICF were used, allowing for a simple and easily readable data analysis. In March 2020, in comparison to March 2019, the average working time of medical workers (p less then 0.001) and the number of hospitalizations (p less then 0.034) decreased significantly. In April 2020, compared to April 2019, the average working time of medical workers ( less then 0.001) and the number of hospitalizations (0.002) also decreased significantly. In addition, in April 2020, the percentage value of the contracted services provided decreased significantly (p = 0.017), which was not observed in March of that year. The COVID-19 pandemic has affected the operation of a non-COVID-19 hospital, causing an increase in staff absences from work, a decrease in the number of hospitalizations and a decrease in the value of the revenue generated from health services provided. The ICF is a useful tool for the evaluation of a hospital's healthcare services.A high-stretch positive temperature coefficient (PTC) surface heating textile (PTC-SHT) was fabricated using a composite of PTC powder and multiwall carbon nanotubes (MWCNTs). The PTC-SHT (heating area = 100 × 100 mm2) was produced by screen-printing the PTC-MWCNT composite paste onto a high-stretch textile with embroidered electrodes. Overall, the temperature increased to 56.1 °C with a power consumption of 5 W over 7 min. Subsequently, the surface temperature of the PTC-SHT remained constant despite the continued decrease in power consumption. This indicated that heating was accompanied by an increase in resistance of the PTC-SHT, which is typical of this process-i.e., heating to a constant temperature under a constant voltage over an extended period of time. In addition, 4.63 W power was required to heat the PTC-SHT surface from an external temperature of 5 to 45 °C in 10 min, after which stable low-temperature heat generation behavior was observed at a constant temperature of 50 °C, which was maintained over 40 min.
