Listeria monocytogenes NCTC10527 was examined with respect to its nonthermal inactivation kinetics in fermented sausages from four European countries: Serbia-Montenegro, Hungary, Croatia, and Bosnia-Herzegovina. The goal was to quantify the effect of fermentation and ripening conditions on L. monocytogenes with the simultaneous presence or absence of bacteriocin-producing lactic acid bacteria (i.e., Lactobacillus sakei). Different models were used to fit the experimental data and to calculate the kinetic parameters. The best model was chosen based on statistical comparisons. The Baranyi model was selected because it fitted the data better in most (73%) of the cases. The results from the challenge experiments and the subsequent statistical analysis indicated that relative to the control condition the addition of L. sakei strains reduced the time required for a 4-log reduction of L. monocytogenes (t4D). In contrast, the addition of the bacteriocins mesenterocin Y and sakacin P decreased the t4D values for only the Serbian product. A case study for risk assessment also was conducted. The data of initial population and t4D collected from all countries were described by a single distribution function. Storage temperature, packaging method, pH, and water activity of the final products were used to calculate the inactivation of L. monocytogenes that might occur during storage of the final product (U.S. Department of Agriculture Pathogen Modeling Program version 7.0). Simulation results indicated that the addition of L. sakei strains significantly decreased the simulated L. monocytogenes concentration of ready-to-eat fermented sausages at the time of consumption.

Various factors causing fatigue in athletes include an increase of lactic acid in muscles. According to the movement patterns of softball athletes, the energy source comes from the Lactaid anaerobic metabolism. Therefore, it is necessary to know the elimination of lactic acid in muscles, reflecting the decrease of lactic acid in the blood. This study aimed to determine the recovery time of lactic acid levels after exercise in 0 minutes, 5 minutes, 10 minutes, and 20 minutes. Accutrend Lactacid measured softball athlete lactic acid levels. The method used in this study was an experimental method with One-Shot Case Study research design, while the research subjects were randomly assigned from the viable softball athlete population in the Student Activity Unit. The samples included 12 athletes. Data analysis employed t-test paired scores with significance p ≤ 0.05 using SPSS V. 20.0 software. The results showed that the lactic acid levels returned to normal, namely the level of 2.79 mMol/L, at 20 minutes of rest. It concludes that that lactic acid levels of softball athletes increased after the start of training, decreased after 5 minutes of rest, and returned to normal in 20 minutes of rest.

Perineal Muscle

Background: Stiff perineum is caused by the nerves of the perineal muscle contain pyruvic acidwhich enters the mitochondria which are converted into lactic acid. Lactic acid causes metabolicproblems and shrinks between the perineal muscle cells, so the perineum becomes stiff. Theimpact of a stiff perineum can inhibit the second stage of labor which increases the risk of death tothe fetus and causes damage to the birth canal or laceration. Research Objectives: to accelerate thesecond stage of labor. Research Method: The design of this study uses the case study method. Thesampling method used was non probability sampling through a purposive sampling approach of 3patients. Patients used as participants were maternity patients in Cilacap District Hospital. Datawas collected from January 2 to January 25, 2019. After tabulation with data that has beenanalyzed using analysis of explanation and time series. Results: The study showed there was agreat impact of the Perineum Massage Midwifery Care for the Acceleration of Second Stage ofLabor in Maternity Women. With the results of the first participant the process of acceleratinglabor took place within 15 minutes. In the second participant, the process of labor accelerationtook place within 10 minutes. And in the third participant the process of accelerating labor tookplace within 20 minutes. Conclusion: Thus, that Perineum Massage Care for the Acceleration ofSecond Stage of Labor is really effective.
