Enhancing awareness of personal cleanliness and antibacterial resistance has intensified the antibacterial substance request on consumable products. Antibacterial agents that have been commercialized nowadays are produced from inorganic and non-renewable substances. This provides several drawbacks, particularly against health and environm.n.al issues. Therefore, m.n. scientists work on substituting fossil-fuel-based antibacterial agents with natural ones such as from biomass. Biomass derivatives, natural abundances of biopolymers in the world, amount to major compounds including polysaccharides (cellulose, hemicellulose, and chitosan) and polyphenol (tannin and lignin) substances which are capable to combat the growth of Gram-positive bacteria and Gram.n.gative bacteria. To date, no report focuses on a deep understanding of antibacterial properties derived from biomass and the internal and external factors effects. This work provides that gap because comprehensive knowledge is necessary before applying biomass to the products. The potency of biomass derivatives as antibacterial additives is also summarized. Basic knowledge of antibacterial characteristics to the application in products is highlighted in this review. Besides, the discussion about challenges and future perspectives is also delivered.

Given a graph g=( V,A ) , we define a space of subgraphs m with the binary operation of union and the unique decomposition property into blocks. This space allows us to discuss a notion of m.n.mal subgraphs (m.n.mal coalitions) that are of interest for the game. Additionally, a partition of the game is defined in terms of the gain of each block, and subsequently, a solution to the game is defined based on distributing to each player (node and edge) present in each block a paym.n. proportional to their contribution to the coalition.

Introduction: necrotizing pancreatitis m.n.gem.n. is complex and varies significantly am.n. clinicians. m.n.mally invasive approaches like transgastric necrosectomy via laparoscopy are emerging as effective treatm.n. options. This case report underscores the technique’s efficacy, clinical outcomes, and role in reducing complications. Clinical Observation: A 59-year-old male with a history of smoking and alcoholism presented with severe abdom.n.l pain, nausea, and vomiting. Over the following weeks, he developed symptoms including asthenia, weight loss, and melena. Diagnostic workup revealed severe anemia and Balthazar E necrotizing pancreatitis, with significant intra-abdom.n.l fluid collections and signs of infection. After initial conservative m.n.gem.n., the patient underwent transgastric necrosectomy via laparoscopy due to deteriorating clinical status. The procedure involved removing necrotic tissue and perform.n. a cystogastroanastomosis and jejunostomy. Postoperative care included fasting, parenteral nutrition, broad-spectrum antibiotics, and enzymatic replacem.n.. The patient recovered well, with reduced necrotic tissue on follow-up imaging, and was discharged twelve days post-surgery [1]. Conclusion: Transgastric necrosectomy by laparoscopy is a valuable first-line surgical option for patients with symptomatic necrotizing pancreatitis, particularly in cases without prior interventions. This m.n.mally invasive technique helps reduce major complications and mortality, offering a less invasive alternative to traditional open necrosectomy. The multidisciplinary approach and careful postoperative m.n.gem.n. were crucial to the patient’s favorable outcome. The case highlights the potential of transgastric necrosectomy as an effective treatm.n. strategy in m.n.ging complex pancreatitis cases, including those with associated duodenal perforation [2].

Background: The protective role of (poly)phenols against metabolic disorders has been extensively studied in adults but not in ***: To assess associations of dietary (poly)phenols and their subclasses with cardiometabolic health parameters in adolescents. methods: A cross-sectional study was conducted in 944 individuals aged 11 to 14 years enrolled in the SI! Program for Secondary Schools trial (nCT03504059). (Poly)phenol intake was assessed using semi-quantitative food frequency questionnaires and the Phenol-Explorer database. The measured cardiometabolic parameters were waist circumference (WC) age-sex z-score， blood pressure (BP) age-sex z-score， blood glucose (BG)， triglycerides (TG)， and high-density lipoprotein cholesterol (HDL-c). multilevel mixed-effect linear regression models were applied to exam.n. the association between (poly)phenol quintiles and cardiometabolic health ***: Compared to the lowest quintile， adolescents in the highest quintile of total (poly)phenol intake had lower WC z-scores (β=-0.09， 95%CI=-0.09;-0.08， P-for trend=0.002)， mean arterial pressure z-scores (β =-0.11， 95%CI=-0.12;-0.09， P-for trend=0.206)， and HDL-c (β=-1.52， 95%CI=-2.90;-0.14， P-for trend=0.108)， after multivariable adjustm.n.. The WC z-scores (β=-0.11， 95%CI=-0.19;-0.03， P-for trend=0.013) and HDL-c (β=-2.16， 95%CI=-3.78;-0.53， P-for trend=0.046) were lower in the highest quintile of flavonoid intake compared to the lowest quintile. The highest quintile of phenolic acid intake was associated with a lower WC z-score (β=-0.14， 95%CI=-0.26;-0.02， P-for trend=0.011) and TG levels (β=-8.83， 95%CI=-12.37;-5.30， P-for trend nd the highest quintile of stilbene intake with lower BG (β=-1.83， 95%CI= -3.103;-0.64， P-for trend nd TG (β=-3.22， 95%CI= -4.95;-1.49， P-for trend=0.034)， and with higher HDL-c (β=2.328， 95%CI= 1.40;3.17， P-for trend=0.466) compared to the lowest quintile.

The possibility of determ.n.ng the integrity of a real structure subjected to non-invasive and non-destructive m.n.toring, such as that carried out by a series of accelerometers placed on the structure, is certainly a goal of extreme and current interest. In the present work, the results obtained from the processing of experim.n.al data of a real structure are shown. The analyzed structure is a lattice structure approximately 9 m high, m.n.tored with 18 uniaxial accelerometers positioned in pairs on 9 different levels. The data used refer to continuous m.n.toring that lasted for a total of 1 year, during which m.n.r damage was caused to the structure by alternatively removing some bracings and repositioning them in the structure. Two methodologies detecting damage based on decomposition techniques of the acquired data were used and tested, as well as a methodology combining the two techniques. The results obtained are extremely interesting, as all the m.n.r damage caused to the structure was identified by the processing methods used, based solely on the m.n.tored data and without any knowledge of the real structure being analyzed. The results use 15 acquisitions in environm.n.al conditions lasting 10 m.n.each, a reasonable amount of time to get immediate feedback on possible damage to the structure. © 2024 The Authors.
