Furthermore, analysis of the separation issues of L-ribose from the reaction solution and different purification methods is presented.Key points•l-Arabinose,l-ribulose and ribitol can be used to producel-ribose by enzymes. • Five enzymes are systematically introduced for production ofl-ribose. • Microbial transformation and enzymatic methods are promising for yieldingl-ribose.As host community diversity decreases, parasite diversity may also decline. The life cycles of trematodes involve multiple hosts from different orders, with many trematodes displaying narrow host specialization. In the 1960s and 2010s, we performed full-body necropsies of juvenile or first-year birds of four wetland bird species, Anas platyrhynchos, Aythya fuligula, Fulica atra, and Chroicocephalus ridibundus which originated from the southern Czech Republic, and examined them for the presence of trematodes. We compared the trematode species richness and diversity of the analyzed component communities. We found complete disintegration of host-parasite networks, which led to declining populations and local extinctions of the majority of trematode species, particularly those with narrow host preferences. For example, in black-headed gulls, 67% of trematode species recorded in the 1960s were absent in gulls that were examined in the 2010s. In contrast, we did not identify any trematode species that were absent in the 1960s but present in the 2010s. This collapse provides new insight into the recent debate regarding whether human-caused extinctions should be considered a problem when locally extinct host species are replaced by an equal or even higher number of nonnative species, thus maintaining local alpha diversities but leading to biotic homogenization and consequently reducing beta diversity. By documenting the collapse of the host-parasite network, we provide a strong argument that biodiversity cannot be assessed by simple measures alone, as only local-scale conservation measures allow the preservation of host-pathogen interactions and nutrient cycles and thus prevent the loss of low-visibility species, such as helminths.The presence of pharmaceuticals, which are considered as contaminants of emerging concern, in natural waters is currently recognized as a widespread problem. Monitoring these contaminants in the environment has been an important field of research since their presence can affect the ecosystems even at very low levels. Several analytical techniques have been developed to detect and quantify trace concentrations of these contaminants in the aquatic environment, namely high-performance liquid chromatography, gas chromatography, and capillary electrophoresis, usually coupled to different types of detectors, which need to be complemented with time-consuming and costly sample cleaning and pre-concentration procedures. Generally, the enzyme-linked immunosorbent assay (ELISA), as other immunoassay methodologies, is mostly used in biological samples (most frequently urine and blood). However, during the last years, the number of studies referring the use of ELISA for the analysis of pharmaceuticals in complex environmental samples has been growing. Therefore, this work aims to present an overview of the application of ELISA for screening and quantification of pharmaceuticals in the aquatic environment, namely in water samples and biological tissues. The experimental procedures together with the main advantages and limitations of the assay are addressed, as well as new incomes related with the application of molecular imprinted polymers to mimic antibodies in similar, but alternative, approaches. Graphical Abstract.BACKGROUND Patient-related risk factors for the development of postoperative pulmonary complications (PPCs) include age ≥ 60-years, congestive heart failure, hypoalbuminemia and smoking. The effect of obesity is unclear and has not been shown to independently increase the likelihood of PPCs in trauma patients undergoing trauma laparotomy. We hypothesized the likelihood of mortality and PPCs would increase as body mass index (BMI) increases in trauma patients undergoing trauma laparotomy. METHODS The Trauma Quality Improvement Program (2010-2016) was queried to identify trauma patients ≥ 18-years-old undergoing trauma laparotomy within 6-h of presentation. A multivariable logistic regression analysis was used to determine the likelihood of PPCs and mortality when stratified by BMI. RESULTS From 8,330 patients, 2,810 (33.7%) were overweight (25-29.9 kg/m2), 1444 (17.3%) obese (30-34.9 kg/m2), 580 (7.0%) severely obese (35-39.9 kg/m2), and 401 (4.8%) morbidly obese (≥ 40 kg/m2). After adjusting for covariates including age, injury severity score, chronic obstructive pulmonary disease, smoking, and rib/lung injury, the likelihood of PPCs increased with increasing BMI overweight (OR = 1.37, CI 1.07-1.74, p = 0.012), obese (OR = 1.44, CI 1.08-1.92, p = 0.014), severely obese (OR = 2.20, CI 1.55-3.14, p  less then  0.001), morbidly obese (OR = 2.42, CI 1.67-3.51, p  less then  0.001), compared to those with normal BMI. In addition, the adjusted likelihood of mortality increased for the morbidly obese (OR = 2.60, CI 1.78-3.80, p  less then  0.001) compared to those with normal BMI. CONCLUSION Obese trauma patients undergoing emergent trauma laparotomy have a high likelihood for both PPCs and mortality, with morbidly obese trauma patients having the highest likelihood for both. This suggests obesity should be accounted for in risk prediction models of trauma patients undergoing laparotomy.Uveitis (JIA-U), the most common extra-articular manifestation in juvenile idiopathic arthritis (JIA), may cause severe impairment of vision in children and affect their quality of life (QoL). Considering the lack of uveitis-related QoL assessment questionnaire, and multidimensional nature of the Juvenile Arthritis Multidimensional Assessment Report (JAMAR), commonly used for monitoring and assessing the health status of children with JIA, we performed a cross-sectional study to investigate the potential of the JAMAR in estimation of QoL in children suffering from JIA-U. buy Semaxanib The study included 42 children with JIA, 21 of whom had JIA-U. Both children and their parents completed the JAMAR. We compared two groups of children (JIA-U and JIA without uveitis) and their parents against five extracted questionnaires items (QoL, functional ability, pain level, disease activity estimation, and current emotional state of the child) using the independent-samples t test to verify the differences and the Pearson correlation coefficient to measure the strength of a linear association between variables.
