Insights into Treponema pallidum genomics from modern and ancient genomes using a novel mapping strategy.

Background: Treponemal diseases are a significant global health risk, presenting challenges to public health and severe consequences to individuals if left untreated. Despite numerous genomic studies on Treponema pallidum and the known possible biases introduced by the choice of the reference genome used for mapping, few investigations have addressed how these biases affect phylogenetic and evolutionary analysis of these bacteria. In this study, we ascertain the importance of selecting an appropriate genomic reference on phylogenetic and evolutionary analyses of T.

Elderflowers ( L.): A Potential Source of Health-Promoting Components.

Elderflowers are used for both culinary and health purposes. Their composition and, therefore, their properties depend on the variety from which they were obtained. The aim of this study was to compare six cultivated varieties with the wild form.

Effect of Cold Brew Coffee Storage in Industrial Production on the Physical-Chemical Characteristics of Final Product.

The purpose of this article is to present information about changes in physical properties (pH, TA, and color) and chemical components with bioactive activity in cold brew coffee beverages, during storage before and after HTST processing. Coffee samples were tested using industrial technology (12,000 bottles per batch). The antioxidant activity of the samples was analyzed using ABTS and FRAP methods, the concentration of polyphenols was determined using the UPLC-MS chromatography coupled with mass spectrometry method, and microbiological tests were performed according to PN-ISO/PN-EN ISO standards.

Comparison of the Chemical Composition of Selected Varieties of Elderberry with Wild Growing Elderberry.

Elderberries of wild-growing shrubs are most often used; however, various cultivated varieties of this shrub appear more and more often. The aim of this research was to compare the fruit composition of specific varieties with those grown wild in urban and ecologically clean conditions. Six varieties of elderberry grown on one experimental farm and two wild-growing samples from the city center and the landscape park were assessed.

Assessing weaning stress - Relations between enamel hypoplasia, δO and δC values in human teeth obtained from early modern cemeteries in Wroclaw, Poland.

Objectives: The aim of this paper is to assess linear enamel hypoplasia (LEH) on canines of adults from early modern Wroclaw cemeteries to compare δC and δO values in enamel formed before, during and after LEH formation, and to attempt to find a link between the selected indicators of the weaning process.

Material And Methods: 15 permanent canines with visible LEH were selected for analysis. Age at LEH formation was estimated using the Reid and Dean method.

Effect of Vacuum Impregnation with Apple-Pear Juice on Content of Bioactive Compounds and Antioxidant Activity of Dried Chokeberry Fruit.

Food technology seeks ways to preserve products while maintaining high bioactive properties. Therefore, an attempt was made to assess the effect of the process of impregnation with apple-pear juice and the drying process on the content of bioactive compounds in chokeberry fruit. Chokeberry fruits were subjected to impregnation with apple-pear juice at three levels of vacuum pressure, 4, 6, and 8 kPa; then, they were dried using microwave-vacuum technology.

Effect of pulsed electric field treatment on shelf life and nutritional value of apple juice.

The aim of this study was to assess shelf life and nutritional value of apple juice, including the content of bioactive compounds, after pulsed electric field (PEF) treatment, taking into account different number of cycles: 4, 6, 8 (total 200, 300, and 400 pulses, respectively). Determination of vitamin C and polyphenols concentration, antioxidant activity as well as microbiological analysis were conducted immediately after PEF process and after 24, 48 and 72 h of storage. The results showed that PEF did not affect the content of bioactive compounds.

Rheological, Chemical and Physical Characteristics of Golden Berry (Physalis peruviana L.) after Convective and Microwave Drying.

Studies on methods for fixing foods (with a slight loss of bioactive compounds) and obtaining attractive products are important with respect to current technology. The drying process allows for a product with highly bioactive properties. Drying of fruit was carried out in a conventional manner, and in a microwave under reduced pressure at 120 W and 480 W.

Comparison of old cherry cultivars grown in Czech Republic by chemical composition and bioactive compounds.

Sweet cherry fruits are readily consumed by humans, and they contain significant quantities of bioactive compounds. Fifteen sweet cherry (Prunus avium L.) old cultivars grown in the Czech Republic were examined.

Effect of Film-Forming Alginate/Chitosan Polyelectrolyte Complex on the Storage Quality of Pork.

Meat is one of the most challenging food products in the context of maintaining quality and safety. The aim of this work was to improve the quality of raw/cooked meat by coating it with sodium alginate (A), chitosan (C), and sodium alginate-chitosan polyelectrolyte complex (PEC) hydrosols. Antioxidant properties of A, C, and PEC hydrosols were determined.

Colour, phenolic content and antioxidant capacity of some fruits dehydrated by a combination of different methods.

The objective of this study was to improve product quality of dehydrated fruits (apple, pear, papaya, mango) using combined drying techniques. This involved investigation of bioactivity, colour, and sensory assessment on colour of the dried products as well as the retention of the bio-active ingredients. The attributes of quality were compared in regard to the quality of dehydrated samples obtained from continuous heat pump (HP) drying technique.
