Black liquor, one of the by-products of pulp and paper industry, is an underexplored resource with greatpotential for the recovery of valuable biopolymers such as lignin and hemicelluloses. In this work, thehemicellulose was recovered from this liquor, containing 17 % of total dissolved solids, using ZnO/polyethersulfone ultrafiltration membrane. The hemicellulose was concentrated into the retentatestream while lignin was permeated through these membranes. The effects of transmembrane pressure(1 to 4 bar), time (up to 8 h) and crossflow velocity (0.1 and 0.2 m/s) were studied for ultrafiltration processoperating in crossflow mode. The highest rejection of hemicellulose was achieved up to 90.7 ± 1.9 %at 4 bar. At 3 bar, the yield of hemicellulose was 90 % and 84 % for the volume reduction up to 60 % and78 %, respectively. Mathematical modeling was applied to analyze the membrane fouling mechanismresponsible for the flux reduction during filtration at constant pressure, as well as to predict the changesin hemicellulose and lignin concentration during the filtration process.

Purpose: Lower urinary tract symptoms are numerous, but the specific impact of each of these symptoms on the quality of life (QoL) has not been evaluated in community-dwelling men. An assessment of these symptoms and their effects on QoL was the focus of this study. Methods: We performed a cross-sectional study with 373 men aged >50 years from a community setting. Patients completed the International Prostate Symptom Score questionnaire, which includes questions on each of the specific urinary symptoms and a question addressing health-related QoL that are graded from 0 to 5. We used the Pearson correlation test to assess the impact of each symptom on QoL. Results: Nocturia (58.9%) was the most prevalent urinary symptom. The mean score was 0.9±1.4 for incomplete emptying, 1.0±1.5 for frequency, 0.9±1.3 for intermittency, 0.8±1.3 for urgency, 1.0±1.5 for weak stream, 0.5±1.0 for straining, and 2.0±1.6 for nocturia. Nocturia and frequency were the only symptoms associated with poorer QoL, with nocturia showing a stronger association. Conclusions: Nocturia affects 50% of community dwelling men aged >50 years, and is the lower urinary tract symptom with the greatest negative impact on QoL.

The capability for Artificial Intelligence in the beauty industry is enormous, as customers are demanding increasingly customized offers that only these strategies can offer. However, there is still a scarcity of empirical research on customer experiences enabled by AI, which highlights this research's relevance, which we intend to bridge.

Sepsis is a major health problem worldwide, with an extremely high rate of morbidity and mortality, partly due to delayed diagnosis during early disease. Currently, sepsis diagnosis requires bacterial culturing of blood samples over several days, whereas PCR-based molecular diagnosis methods are faster but lack sensitivity. The use of biosensors containing nucleic acid aptamers that bind targets with high affinity and specificity could accelerate sepsis diagnosis. Previously, we used the systematic evolution of ligands by exponential enrichment technique to develop the aptamers Antibac1 and Antibac2, targeting the ubiquitous bacterial peptidoglycan. Here, we show that these aptamers bind to four gram-positive and seven gram-negative bacterial sepsis agents with high binding efficiency. Thus, these aptamers could be used in combination as biological recognition elements in the development of biosensors that are an alternative to rapid bacteria detection, since they could provide culture and amplification-free tests for rapid clinical sepsis diagnosis.
