84 (CI-0.79-0.87). Agreement diminished with protocol A to ICC=0.62 (CI-0.37-0.76) and improved with protocol B to ICC=0.90 (CI-0.86-0.92). Intra-observer agreement without protocol was ICC=0.87, with protocol A ICC=0.87, and with protocol B ICC=0.93. The biggest improvement was seen for urologists’ agreement from no protocol to protocol B, where ICC improved from 0.81 (CI-0.70-0.87) to 0.91 (CI-0.84-0.94). CONCLUSIONS Observer agreement of HU measurement of urolithiasis without protocol is already good but using zoom, bone setting, and measuring in a representative plane is recommended. SCH900353 This protocol results in higher agreement, especially among urologists. Measuring in 3 axial planes does not increase agreement.The n-3 and n-6 polyunsaturated fatty acids (PUFA) are among the most studied nutrients in human metabolism. In the past few decades, prospective studies and controlled trials have supported the view that the effects of these essential fatty acids are clinically relevant. PUFA profiles in different blood compartments are reflections of both diet and metabolism, and their levels may be related to disease risk. Despite widespread interest, there is no consensus regarding which biomarkers best reflect PUFA status in the body. The measurement of PUFA levels is not straight-forward, and a wide variety of indices have been used in clinical studies, producing conflicting results. A major source of heterogeneity among studies is associated with research design, sampling, and laboratory analyses. To date, the n-3 index, n-6/n-3 ratio, and arachidonic acid (AA)/eicosapentaenoic acid (EPA) ratio are the most promising biomarkers associated with PUFA metabolism. Although hotly debated, these indices may be considered at least markers, if not risk factors, for several diseases, especially cardiovascular events and brain disorders. Here, we summarize the most updated evidence of n-3 and n-6 PUFA effects on human health, reviewing current controversies on the aforementioned indices and whether they can be considered valuable predictors of clinical outcomes.Aim This study examines how chimeric antigen receptor T-cell (CAR-T) therapy’s incremental effectiveness and cost-effectiveness profile fits into the recent history of anticancer treatments. Materials & methods We conducted graphical and multivariable analyses using data from the Cost-Effectiveness Analysis Registry of the Tufts Medical Center and the Institute for Clinical and Economic Review’s analysis of CAR-T therapies. We collected additional information including the US FDA approval years for pharmacologic innovations. Results CAR-T provided 5.03 (95% CI 3.88-6.18) more incremental quality-adjusted life-years than the average pharmaceutical intervention and 4.61 (95% CI 1.67-7.56) more than the average nonpharmaceutical intervention, while retaining similar cost-effectiveness. There was evidence of worsening cost-effectiveness by approval year for pharmaceutical interventions. Limitations Analysis is limited to anticancer treatments studied in cost-utility analyses, estimated to cover approximately 60% of FDA-approved antineoplastic agents. Conclusion CAR-T therapy breaks a pattern of stagnant efficacy growth in pharmaceutical innovation and demonstrates significantly greater incremental effectiveness and similar cost-effectiveness to prior innovations.Digestion and health properties of food do not solely rely on the sum of nutrients but are also influenced by food structure. Dairy products present an array of structures due to differences in the origin of milk components and the changes induced by processing. Some dairy structures have been observed to induce specific effects on digestion rates and physiological responses. However, the underlying mechanisms are not fully understood. Gastric digestion plays a key role in controlling digestion kinetics. The main objective of this review is to expose the relevance of gastric phase as the link between dairy structures and physiological responses. The focus is on human and animal studies, and physiological relevant in vitro digestion models. Data collected showed that the structure of dairy products have a profound impact on rate of nutrient bioavailability, absorption and physiological responses, suggesting gastric digestion as the main driver. Control of gastric digestion can be a tool for delivering specific rates of nutrient digestion. Therefore, the design of food structure targeting specific gastric behavior could be of great interest for particular population needs e.g. rapid nutrient digestion will benefit elderly, and slow nutrient digestion could help to enhance satiety.Francisella tularensis is a Gram-negative bacterium that causes the zoonotic disease tularemia. The historical development of tularemia as a biological weapon has led to it being characterized by the CDC as a category A biothreat agent. Neither posttranslational modification (PTM) of proteins, in particular lysine acetylation, in Francisella nor its subsequent regulation of the protein activity has been well studied. In this work, we analyze N-ε-lysine acetylation of the F. tularensis ssp. novicida proteome by mass spectrometry for the first time. To create a comprehensive acetylation profile, we enriched protein acetylation using two approaches (1) the addition of glucose or acetate into the culture medium and (2) direct chemical acetylation of N-ε-lysines with acetyl phosphate. We discovered 280 acetylated proteins with 1178 acetylation sites in the F. tularensis ssp. novicida strain U112. Lysine acetylation is an important PTM that regulates multiple cellular processes in bacteria, including metabolism, transcription, translation, stress response, and protein folding. We discovered that Francisella chitinases A and B are acetylated naturally and when chemically induced by acetyl phosphate. Moreover, chemical overacetylation of chitinases results in silencing of the enzymatic activity. Our findings suggest a novel mechanism of posttranslational regulation of the chitinase activity and that acetylation may play a role in Francisella’s regulation of the protein activity.
