The liquid shampoo is a product that is generally used to clean hair and scalp. The additional active ingredient used in the liquid shampoo is neem leaves which contain polyphenols that have antibacterial effects. Neem leaves extract was made by hot infusion method with coconut oil as a solvent. The purposes of this research were to find the best concentration of neem leaves infused oil for liquid shampoo material and compare the qualities of liquid shampoo with Indonesian National Standard (SNI) of Shampoo 06-2692-1992. The method of this research was a laboratory experiment with descriptive analysis. This research was conducted in five treatments. Concentration neem leaves infused oil for liquid shampoo materials were ratio between coconut oil and neem leaves in sample A = 720:0 (w/w); B = 720:22,5 (w/w); C = 720:30 (w/w); D = 720:45 (w/w); and E = 720:90 (w/w). The result showed that all of the shampoos met the SNI of Shampoo 06-2692-1992 according to organoleptic, moisture content, and pH. The best shampoo based on organoleptic observation was shampoo C (720:30 (w/w)) with a hedonic percentage of 40%, moisture content of 69.89%, pH 7.03, and specific gravity of 1.0223 g/g. The highest antibacterial activity against S. aureus was shampoo E (720:90 (w/w)) with an inhibition zone diameter was 9.5 mm. Shampoo with the highest antibacterial activity resulted from the highest addition of coconut oils infused Neem leaves. It proved that neem leaves were effective as an additive in making shampoo to boost its antimicrobial properties.

Abstract Increasing the quality and reliable reproducibility of large-size composite structures molding using the vacuum infusion method, which is gaining popularity in various industries, is achieved in practice through numerous tests by try and errors that require significant costs and time. The purpose of these tests is to determine the layout of the ports for the resin injection and vacuum supply, as well as the temperature regime that ensures the absence of isolated non-impregnated zones, the minimum porosity and the required reinforcement volume fraction in the composite. The proposed approach removes the simplifying assumptions used in commercial software for modeling the process, which reduce the accuracy of reconstruction of its dynamics and the sensitivity to the formation of unrepairable defects such as dry spots. It involves multiphysics modeling of resin filling in a porous preform by describing the resin front dynamics by the phase field equation, pressure distribution in an unsaturated porous medium by the Richards equation, the evolution of the degree of cure by the convection / diffusion / thermokinetics equation, and thermal processes by the heat transfer equation using modified models of viscosity, the diffusion coefficient of the degree of cure, the boundary condition for the vacuum port. To reduce the finite element computation time of the investigated variants of the process, which is necessary for its computer optimization, the predictive partial sub-criteria were used, which give a reliable prediction before the beginning of the resin gel and solidification. Due to this, a gain in computation time is 30-50% with a significant prediction accuracy of quality objectives and the presence of possible defects.

Abstract Purpose. Given the recent and rapid development of peptide receptor radionuclide therapy (PRRT), increasing emphasis should be placed on the early identification and quantification of therapeutic radiopharmaceutical (thRPM) extravasation during intravenous administration. Herein, we provide an analytical model of 177Lu-DOTA0-Tyr3-octreotate (Lutathera®) infusion for real-time detection and characterization of thRPM extravasation. Methods. For 33 Lutathera®-based PRRT procedures using the gravity infusion method, equivalent dose rates (EDRs) were monitored at the patient’s arm. Models of flow dynamics for nonextravasated and extravasated infusions were elaborated and compared to experimental data through an equivalent dose rate (EDR) calibration. Nonextravasated infusion was modeled by assuming constant volume dilution of 177Lu activity concentration in the vial and Poiseuille-like laminar flow through the tubing and patient vein. Extravasated infusions were modeled according to their onset times by considering elliptically shaped extravasation with different aspect ratios. Results. Over the 33 procedures, the peak of the median EDR was reached 14 min after the start of the infusion with a value of 450 uSv/h. On the basis of experimental measurements, 1 mSv/h was considered the empirical threshold for Lutathera® extravasation requiring cessation of the infusion and start again with a new route of injection. According to our model, the concentration of extravascular activity was directly related to the time of extravasation onset and its duration, a finding inherent in the gravity infusion method. This result should be considered when planning therapeutic strategy in the case of RPM extravasation because the local absorbed dose for β-emitters is closely linked to activity concentration. For selected EDR values, charts of extravasated activity, volume, and activity concentration were computed for extravasation characterization. Conclusion. We proposed an analytical model of Lutathera® infusion and extravasation (gravity method) based on EDR monitoring. This approach could be useful for the early detection of thRPM extravasation and for the real-time assessment of activity concentration and volume accumulation in the extravascular medium.

Tomato is a fruit of great commercial importance and highly cultivated. However, postharvest losses represent one of the main problems of this crop and can be minimized as alternative techniques. Therefore, the objective of the present work was to maintain tomato firmness by applying calcium chloride-associated pectin-methylesterase (PME) by the vacuum infusion method. Tomatoes of cultivar IAP-6 were submitted to vacuum infusion with water, vacuum infusion with 5% calcium chloride and vacuum infusion with PME associated with 5% calcium chloride, fruits without infusion were used as control. Fresh mass loss, fruit firmness, peel color, soluble solids content, pH, total acidity, PME activity and calcium activity were evaluated. The experiment was carried out in a completely randomized design in a 4x5 factorial scheme with three replications for 12 days, evaluated every 3 days. The means were compared using the Tukey test (p <0.05). Data were analyzed graphically with confidence interval (CI p <0.05). Regarding the loss of fresh mass there was an increase over time in all treatments. The PME + CaCl2 5% treatment was the most suitable for reducing firmness loss, as well as presenting the smallest variation of PME activity, as well as low levels of organic acids. Therefore, vacuum infusion with PME + CaCl2 in tomatoes maintains acceptable firmness and physicochemical characteristics as well as CaCl2 infusion.

Purpose: It is routine to administer oxytocin following delivery of the neonate during cesarean section. However, there are many kinds of administration methods. Heesen et al. published an international consensus statement in 2019 on the use of uterotonic agents, including oxytocin during cesarean section [1]. Our institution adapted the guideline-based oxytocin infusion method. We verified the validity of the new approach after one year. Methods: A single-center retrospective study of consecutive patients who underwent cesarean section with a new protocol or the conventional manner from November 2019 to December 2020 was conducted. The primary endpoint was a significant difference in the amount of intraoperative hemorrhage and the total oxytocin amount. Secondary endpoints included differences in the incidence of intraoperative complications. Results: The study included 174 patients: 66 in the new protocol group and 108 in the conventional group. There was a statistically significant difference between the two groups for oxytocin amount (new protocol 4.2 [3.2-5.9] vs. conventional 5.0 [5.0-10] IU, p<0.01) with equivalent intraoperative hemorrhages (new protocol 558 [337-963] vs. conventional 683 [484-1012] g, p=0.08). There was no significant difference in the incidence of nausea. Conclusion: The new guideline-based oxytocin administration safely decreased the intraoperative oxytocin amount in our institution.
