Free sucrose, lactose, galactose, glucose and fructose were determined in yoghurts, milk and honey using on-line coupling of capillary electrophoresis with microdialysis. The dairy products were diluted 50-fold with 10 mmol/L NaOH and sampled using laboratory-made microdialysis probes. The microdialysate was brought to the entrance of the electrophoretic capillary and the coupling consisted in a polydimethylsiloxane (PDMS) cross connector working in the flow-gating interface regime. The electrophoretic analysis was performed in 50 mmol/L NaOH (pH 12.6) background electrolyte, where baseline separation of the five saccharides was achieved in 3.5 min. The LOQs varied in the range 2.3-7.3 mg/L, the number of separation plates varied between 176,000 plates/m for glucose to 326,000 plates/m for galactose and the relative standard deviation (RSD) for ten consecutive analyses of fruit yoghurt was 0.2% for the migration time and 4.4-7.6% for the peak area. The debittering of natural table olives is a very slow process. The effect of acetic, lactic and citric acids on the hydrolysis rate of oleuropein was studied in vitro and at pilot plant scale. The acid hydrolysis of oleuropein was faster with lactic and citric acids than acetic acid, running the experiments at the same pH of 3.8-4.0 units. The temperature exerted a high effect of the hydrolysis of oleuropein in a range of 10-30 °C and the concentration of the organic acid did not show a significant trend. Moreover, the in vitro results were confirmed with three lots of olives that presented a higher content of oleuropein after 3-7 months of preservation when they were processed with acetic acid rather than lactic acid and the opposite for hydroxytyrosol. These results open the possibility of accelerating the debittering of natural olives by preserving them with lactic acid instead of acetic acid. This study evaluated structural and technological properties of beef emulsion modeling systems prepared with tropical flours. Treatments consisted of a control (0% flour inclusion) and three inclusion levels (1%, 2% and 4%) of two breadfruit flours and a banana flour. Flour type affected starch content of cooked beef emulsions, with greater starch content for emulsions prepared with banana flour compared with breadfruit flour, yet flour type did not affect cooking loss. Hardness and chewiness of cooked beef emulsion prepared with breadfruit flour decreased as inclusion level increased from 0% to 4%, while hardness was not affected by inclusion level of banana flour. Redness values of cooked beef emulsions increased as flour inclusion level increased, but were not affected by flour type. Evaluation of the beef emulsion microstructure and storage modulus revealed that the starch granules of banana flour behaved remarkably different than breadfruit flour. Overall, there were positive structural and technological attributes when tropical flours were included in beef emulsions. BACKGROUND Medications for opioid use disorder (OUD) are the most effective treatment for OUD, but uptake of these life-saving medications has been extremely limited in US prisons and jail settings, and limited data are available to guide policy decisions. The objective of this study was to estimate the impact of screening and treatment with medications for OUD in US prisons and jails on post-release opioid-related mortality. METHODS We used data from the National Center for Vital Statistics, the Bureau of Justice Statistics, and relevant literature to construct Monte Carlo simulations of a counterfactual scenario in which wide scale uptake of screening and treatment with medications for OUD occurred in US prisons and jails in 2016. RESULTS Our model predicted that 1840 (95% Simulation Interval [SI] -2757 - 4959) lives would have been saved nationally if all persons who were clinically indicated had received medications for OUD while incarcerated. The model also predicted that approximately 4400 (95% SI 2675 - 5557) lives would have been saved nationally if all persons who were clinically indicated had received medications for OUD while incarcerated and were retained in treatment post-release. These estimates correspond to 668 (95% SI -1008 - 1812) and 1609 (95% SI 972 - 2037) lives saved per 10,000 persons incarcerated, respectively. CONCLUSIONS Prison and jail-based programs that comprehensively screen and provide treatment with medications for OUD have the potential to produce substantial reductions in opioid-related overdose deaths in a high-risk population; however, retention on treatment post-release is a key driver of population level impact. Food protein-induced allergies are primarily aggravated due to imbalance immune responses. Earlier studies by different research groups have reported that the intervention of Lactobacillus pentosus (L. Bemnifosbuvir cost pentosus) S-PT84 can modulate T-helper (Th)1/Th2 balance through regulatory T cells and can effectively promote type 1 immunity by activating dendritic cells and natural killer cells, such biological activity makes L. pentosus S-PT84 a potential mediation in controlling food allergy. Thus, this study aimed to evaluate the effects of L. pentosus S-PT84 against egg ovalbumin (OVA)-induced allergic response in mice. BALB/c mice (n = 12/group) were sensitized with OVA (50 μg/mice) via intraperitoneal injection (IP) for four weeks and subsequently administered with three different doses of L. pentosus S-PT84 via pelleted diet. The allergenic status was assessed by clinical signs, serum histamine, mouse mast cell protease (MMCP) level, and antibody activity, cytokines level in splenocytes, and expression of T regulatory cells (T-regs) in blood. The intervention of L. pentosus S-PT84, precisely at the high dose (0.6 % L. pentosus S-PT84 in pelleted diet) group, significantly reduced the clinical allergenic symptoms and reduced the histamine and MMCP levels in serum. However, the intervention of L. pentosus S-PT84 did not affect the OVA-specific IgE, IgG concentration, but led to lower the total IgE and IgG titers, suggesting that the therapeutic effect of L. pentosus S-PT84 may be due to development of immune tolerance. Moreover, differences in the immune response were observed after L. pentosus S-PT84 intervention, as it significantly reduced the production of IL-4, IL-17, and increased the population of CD25+Foxp3+ cells. Thus, it can be concluded that the intervention of L. pentosus S-PT84 provides a potential therapeutic strategy to reduce the chicken egg OVA-induced allergic symptoms. OBJECTIVE Electronic dance music (EDM) party attendees are a high-risk population for drug use and associated adverse effects. We examined trends in past-year drug use within this population to better inform prevention and harm reduction efforts. METHODS Each summer from 2016 through 2019, we used time-space sampling to survey a cross-section of adults entering EDM parties at randomly selected nightclubs and at dance festivals in New York City. Ns ranged from 504 (2019) to 1,087 (2016). We estimated log-linear trends in past-year use of 16 different synthetic drugs or drug classes. RESULTS Between 2016 and 2019, estimated past-year prevalence of use of ketamine increased from 5.9% to 15.3% (a 157.6% relative increase; P = .007), LSD use increased from 9.9% to 16.6% (a 67.7% relative increase, P 3 drugs increased from 12.7% to 20.5% (a 61.4% relative increase; P = .013); however, estimated past-year use of unknown powders decreased from 2.0% to 1.1% (a relative 44.7% decrease; P = .038) and ecstasy/MDMA/Molly use was stable across years (at 25.0 to 28.5 %; P = .687). CONCLUSIONS Reports of powder cocaine, LSD, ketamine, and GHB are becoming more prevalent among EDM party attendees. Prevention and harm reduction efforts are needed to address increasing use. Research is also needed to examine whether increasing media coverage of medical use of ketamine and other psychedelics affects prevalence of recreational use. Advance guide signs for exit ramps along urban expressways are increasingly critical, enhancing safety and mobility by improving the flow of vehicles exiting urban expressways. However, research has devoted scant attention to advance guide signs for exit ramps. This study aimed to identify and propose optimal design alternatives for exit ramp advance guide signs for different types of exit spacing. This study conducted a driving simulation experiment consisting of five design alternatives of advance guide signs and two exit ramp spacing variation. Eight indicators were measured. The repeated-measure analysis of variances (ANOVA) and the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) were performed for the influence analysis and efficiency evaluation of different schemes. Influence analysis results showed better design alternatives in five schemes of advance guide signs, enabling drivers to more easily locate destination exits and change lanes fewer times, in addition to reducing drivers' need to decelerate, and improving traffic flow in the key influence range of destination exit ramps. The percentage of drivers successfully locating the destination exits also increased with optimal design alternatives of advance guide signs. When the exit ramp spacing tightened, on the other hand, drivers had to make more lane changes and accelerate and decelerate more frequently in the key influence range. As a result, a lower percentage of drivers successfully located destination exits. Efficiency evaluation results were also obtained. In tight spacing, three advance guide signs are recommended to be placed at 1 km, 0.5 km and 0 km prior to the beginning of the tapered deceleration lane. If conditions are limited, at least two advance guide signs should be used. With greater spacing, four advance guide signs are recommended, located at 2 km, 1 km, 0.5 km, and 0 km prior to the beginning of the tapered deceleration lane. If road conditions are limited, three advance guide signs should be used. The mechanisms of melanoma metastasis have been the subject of extensive research for decades. Improved diagnostic and therapeutic strategies are of increasing importance for the treatment of melanoma due to its high burden of mortality in the advanced stages of the disease. Intercellular communication is a critical event for the progression of cancer. Collective evidence suggests that exosomes, small extracellular membrane vesicles released by the cells, are important facilitators of intercellular communication between the cells and the surrounding environment. Although the emerging field of exosomes is rapidly gaining traction in the scientific community, there is limited knowledge regarding the role of exosomes in melanoma. This review discusses the multifaceted role of melanoma-derived exosomes in promoting the process of metastasis by modulating the invasive and angiogenic capacity of malignant cells. The future implications of exosome research and the therapeutic potential of exosomes are also discussed. Biowaste material is a good candidate for the production of energy in urban territories. The presence of undesirable or constituents mixed with the biowaste collected by municipalities makes it difficult to recycle organic matter of sufficient quality for agricultural uses. Methane production is particularly attractive for energy recovery notably because this energy vector can be distributed using the grid already in place for natural gas in many cities. Depending on the origin and biochemical composition of biowaste, methane can be produced using thermochemical (gasification then syngas methanation) or biological processes (anaerobic digestion). The objective of this work was to characterize the ability of biowaste to be used as a feedstock for anaerobic digestion. Based on considerations such as the quantities produced and the availability, four categories of biowaste produced in the city of Lyon were identified as potential key resources Garden biowaste (GBW), restauration biowaste (RBW), household biowaste (HBW) and supermarkets biowaste (SMBW).
