Tetracycline and analogues are among the most used antibiotics in the dairy industry. Besides the therapeutic uses, tetracyclines are often incorporated into livestock feed as growth promoters. A considerable amount of antibiotics is released unaltered through milk from dairy animals. The presence of antibiotic residues in milk and their subsequent consumption can lead to potential health impacts, including cancer, hypersensitivity reactions, and the development of antibiotic resistance. Thus, it is important to monitor residual levels of tetracyclines in milk. The purpose of this study is to develop a quick and simple method for simultaneously extracting five tetracycline analogues from bovine milk. Specifically, five tetracycline analogues: Chlortetracycline (CTC), demeclocycline (DEM), doxycycline (DC), minocycline (MC), and tetracycline (TC) were simultaneously extracted from milk using trifluoroacetic acid. Subsequently, the extracted analogues were separated by reverse-phase high-performance liquid chromatography (RP-HPLC) and detected at 355 nm using UV/Vis. Calibration curves for all five tetracycline analogues show excellent linearity (r2 value > 0.99). Percent recovery for MC, TC, DEM, CTC, and DC were: 31.88%, 96.91%, 151.29, 99.20%, and 85.58% respectively. The developed extraction method has good precision (RSD < 9.9% for 4 of the 5 analogues). The developed method with minimal sample preparation and pretreatment has the potential to serve as an initial screening test.

Context: Breast cancer is a high-mortality disease. Early detection has considerably reduced mortality in developed countries. Objectives: To assess the knowledge, attitudes and practices of Congolese women in Kinshasa on breast cancer, their levels and to identify factors associated with insufficient knowledge, negative attitudes and non-beneficial practices. Material and Methods: This was a descriptive cross-sectional study with analytical aims, carried out from June 1 to September 30, 2023, in Kinshasa. It involved 1170 female respondents, aged 18 to 65, who agreed to take part in the survey. Data were collected using a pre-established questionnaire. Data analysis was performed using SPSS software version 20.0. The study variables were socio-demographics, morbid history, knowledge, attitudes and practices of respondents regarding breast cancer. Statistical measures and tests used were Mean ± standard deviation, median, proportions, logistic regression Backward stepwise and p Results: 60% had insufficient knowledge, 75% had negative attitudes and 80% had non-beneficial practices. The risk factors common to insufficient knowledge, negative attitudes and non-beneficial practices towards breast cancer were low level of education, membership of revivalist or Muslim churches, and primiparity. Conclusion: 60% of Congolese women in Kinshasa have insufficient knowledge about breast cancer, 75% have negative attitudes and 80% have non-beneficial practices, with a positive association between insufficient knowledge and negative attitudes on the one hand, and insufficient knowledge and non-beneficial practices on the other. In this context, increasing the population’s literacy and access to information are essential.

We study the long time formation of rarefaction waves appearing in balance laws by means of singular perturbation methods. The balance laws are non standard because they contain a variable u that appears only in the flux terms. We present a concrete example occurring in flow of steam, nitrogen and water in porous media and an abstract example for a class of systems of three equations. In the concrete example the zero-order equations resulting from the expansion yield a type of conservation law system called compositional model in Petroleum Engineering. In this work we show how compositional models originate from physically more fundamental systems of balance laws. Under appropriate conditions, we prove that certain solutions of the system of balance laws decay with time to rarefaction wave solutions in the compositional model originating from the system of balance laws.

Water quality impact due to excessive nutrients has been extensively studied. In recent years, however, micro-pollutants such as pharmaceuticals and hormonal products used in animal agriculture have added an additional impact to overall water quality. Pharmaceuticals used in the poultry, swine, beef, and dairy industries have been detected in various environmental matrices such as, soil, groundwater and surface water. In this study, 26 surface water samples were collected throughout the Bosque River Watershed （BRW） with samples representing a range of land use conditions and locations of major dairy operations. Samples were analyzed using commercially available Enzyme-Linked Immunosorbent Assay test. Of the 26 samples, three samples consistently tested positive for monensin antibiotic with concentration ranging from 0.30 to 3.41 μg/L. These three samples were collected from sites that received varying amount of agriculture wastes （11.7% to 31.3%） and located downstream from sites associated with moderate levels of animal agriculture. The preliminary results suggest that there is a potential for monensin occurrence in the BRW, although initial findings indicate only very low levels.
