Extraction is crucial for herbal extraction to ensure high quality of bioactive compounds from natural herbs. In the current work, Zingiber Zerumbet was extracted via subcritical water extraction (SWE) and is compared with the conventional solvent extraction, Soxhlet. The quality of the extract was investigated in terms of zerumbone concentration, radical scavenging activity (RSA) and total phenolic content (TPC). For zerumbone concentration, extraction via SWE gave 19.82 ±0.004 mg/g as compared with Soxhlet; 28.51±0.079 mg/g. However, the extraction time required for SWE to yield such concentration only required 40 minutes instead of Soxhlet which took 480 minutes. The same trend was recorded for RSA, which yielded 60.70±0.070% inhibition for SWE and 68.81±0.024% inhibition from Soxhlet extraction. In contrast to TPC, SWE recorded a higher response than Soxhlet extraction, which was 19.19±0.003 mgGAE/g DW, while Soxhlet; 8.30±0.019 mgGAE/g DW. Therefore, the SWE method is more favorable for obtaining a higher value of TPC, slightly good in antioxidant properties but lower zerumbone concentration value than organic solvent extraction. However, the reduced extraction time was almost 12 times quicker for SWE when compared with Soxhlet extraction. Overall, SWE is a promising alternative environmentally friendly since it only uses water as solvent and is comparable to the conventional method.

The prevalence of antibodies to HCV (anti-HCV) in patients undergoing maintenance dialysis therapy (MDT) was found to be one of the highest among different risk groups and there is wide variation in the prevalence of HCV infection among different dialysis units and countries. Therefore, the prevalence of anti-HCV was studied in patients undergoing MDT. The current study is a cross section one, where a sample of 361 HD patients were selected randomly from HD centers in three governmental hospitals in Makkah city and they were subjected to assessment for the prevalence of anti-HCV by using questionnaires in addition to clinical measurements. The overall prevalence of anti-HCV among HD patients was 49.9% according to clinical measurements and questionnaires. The overall prevalence of anti-HCV among HD patients in Makkah city (49.9%) was comparable to that reported from other parts of the Kingdom of Saudi Arabia (KSA) and it is almost similar to the already reported positivity rate of (43.2%) from the eastern region of KSA and southern regions of KSA (45.5%). However, strict adherence to universal precautions as recommended by the Center for Diseases Control (CDC), meticulous regular disinfection of HD machines, strict isolation of HCV-positive patients, dedicated dialysis machines and nursing staff at new dialysis set-up could possibly be the reasons of relatively low anti-HCV positivity at the current study than that reported by Shaheen et al [34], from four centers in the western region of KSA, (72.3%) and that by Huraib et al [29] in their multi-center study in KSA, (68%) as well as the mean national rate. On the other hand, the use of more sensitive third generation enzyme - linked immunosorbent assay (ELISA) technique, long duration on HD, multiple blood transfusions, patients with dialysis treatment in multi-centers, factors related to infrastructure, environment and operational system might be responsible for the high prevalence of anti-HCV found in this study than that reported by Saeed, et al from Riyadh and those observed in the central region of KSA. Although routes of transmission are still unclear, early detection of all infected patients is mandatory for HCV prophylaxis in HD patients. Furthermore, an intensive educational program for staff members, HD patients and proper evaluation of the HD situation are needed. Thus, observation of appropriate preventive measures by all HD-centers is paramount.

Biodiesel is regarded as one of the most beneficial forms of renewable energy, with qualities similar to diesel fuel. Commercially, biodiesel is used in the form of blends – a mixture of diesel and biodiesel, and they have proven to reduce hazardous emissions in the environment. The desire for Euro 5 fuel adoption is essential to meet growing market demands and limited legal emission restrictions. An installation of pricey special equipment is required for measuring the emission based on the European Union legislation. Therefore this paper proposes a calculation method of conversion for percentage volumetric emission into specific emission (g/km).

Objective: to conduct a comprehensive analysis of the clinical, functional, hemodynamic profile of patients with pulmonary arterial hypertension associated with congenital heart disease (PAH-CHD) according to the Russian Registry.

Materials and methods: The study involved 30 patients with Eisenmenger syndrome, 25 patients with PAH associated with prevalent systemic-to-pulmonary shunts and 26 patients with PAH after defect correction. All patients had been entered in the Russian registry (NCT03707561). A comparative analysis of clinical, functional, hemodynamic parameters was held. The diagnosis was established by the algorithm proposed in the Russian guidelines for the diagnosis and treatment of PH (2016).

Results: The patients of three subgroups of PAH-CHD were comparable in age and sex. The time from the onset of symptoms to the final diagnosis in the first and second PAH-CHD subgroups was significantly longer: on average, it took three years to establish the diagnosis, whereas in patients with PAH after defect correction, on average, after 9 months the correct diagnosis was made (p=0,0006). Patients with Eisenmenger syndrome were characterized by significantly high values of mean pulmonary artery pressure (mPAP) and pulmonary vascular resistance (PVR) according to right heart catheterization (mPAP (81,0 [72,0;92,0] mm Hg against 52,0 [41,0;75,0] mm Hg, p=0,001 and PVR 2329,0 [1333,0;2778,0] dyn*sec*cm-5 vs. 954,5 [591,0;1439,0] dyn*sec*cm-5, p=0,02) compared with the second subgroup of PAH-CHD, and significant decrease in arterial blood oxygen saturation (SpO2) (90,0 [85,0;93,0]% vs. 94,5 [92,5;96,0]% and 96,0 [92,0;98;0]%) compared with patients of the other subgroups (p=0,002).

Conclusions: Patients with PAH-CHD are a heterogeneous population, the division of which is presented in the clinical classification, and therefore have a different course of the disease. Analyzing the data of patients with PAH-CHD, we found various clinical, functional, physical and hemodynamic features of these patients. With comparable 6MWT and FC (WHO), patients with Eisenmenger syndrome have the highest values of PAP and PVR, as well as lower values of arterial blood oxygen saturation compared to other subgroups of PAH-CHD. In the group of patients with PAH associated with prevalent systemic-to-pulmonary PVR was significantly less compared to other groups of PAH-CHD. In patients with PAH after defect closure, the correlation between 6MWT and FC (WHO) and the area of the right atrium was detected. The obtained data can be useful in the choice of management of these patients

This article presents the impact of changing the operating parameters of a building’s indoor climate systems on a building’s management system. The study is performed using the dynamic energy modelling program DesignBuilder. The created dynamic energy model is based on the documentation of an actual administrative building and the data recorded by the building management system. The developed model changes the operating modes and parameters of the components of microclimate systems. After the changes, simulations are performed to obtain new results for the building’s energy needs. These results are compared, and the impact of different parameters on energy consumption is analyzed. The study found that a proper setting of indoor climate performance can lead to a 26% reduction in heat and a 7% reduction in cooling costs, which does not adversely affect the comfort of the people.

The Imaging X-ray Polarimetry Explorer (IXPE) is a NASA Small Explorer mission—in partnership with the Italian Space Agency—dedicated to X-ray polarimetry in the 2–8 keV energy band. The IXPE telescope comprises three grazing incidence mirror modules coupled to three detector units hosting each one a Gas Pixel Detector, a gas detector that allows measuring the polarization degree by using the photoelectric effect. A wide and accurate ground calibration was carried out on the IXPE Detector Units at INAF-IAPS, in Italy, where a dedicated facility was setup at this aim. In this paper, we present the results obtained from this calibration campaign to study the IXPE focal plane detector response to polarized radiation. In particular, we report on the modulation factor, which is the main parameter to estimate the sensitivity of a polarimeter.
