This article has an associated First Person interview with the first author of the paper.Hair braiding that incorporates synthetic extensions has increased in popularity across all age groups. As part of the styling process, the ends of the braid are commonly dipped in scalding water; an increasing number of patients have presented to our center after containers of recently boiled water are accidentally tipped over and spilled onto patients. A retrospective chart review was performed of all patients who sustained burn injuries related to at-home hair braiding presenting to an ABA-verified burn center between January 1, 2006 and July 31, 2020. A total of 41 patients presented over the study period, and the frequency of this type of burn increased over time, with 54% of injuries occurring in the past 3 years (2018-2020). The mean patient age was 7.5 years, and the majority of patients were under 18 years of age (97%), female (95%), and African-American (98%). Seventy-three percent of injuries occurred in the home and 88% involved another person in the hair braiding process. The mean TBSA burned was 5% (range 1-20%). The most commonly involved areas were the back (54%), thigh/leg (37%), and neck (24%). Ninety percent were partial-thickness injuries only, with 10% having some degree of full-thickness injury. Ninety percent of patients required inpatient admission, and 34% of patients required at least one operative procedure. Hair braiding, with the use of scalding water to seal and set the ends of braids, can lead to burn injuries that require hospitalization and the need for surgical intervention.Plants produce a broad variety of specialized metabolites with distinct biological activities and potential applications. Despite this potential, most biosynthetic pathways governing specialized metabolite production remain largely unresolved across the plant kingdom. The rapid advancement of genetics and biochemical tools has enhanced our ability to identify plant specialized metabolic pathways. Further advancements in transgenic technology and synthetic biology approaches have extended this to a desire to design new pathways or move existing pathways into new systems to address long-running difficulties in crop systems. This includes improving abiotic and biotic stress resistance, boosting nutritional content, etc. In this review, we assess the potential and limitations for (1) identifying specialized metabolic pathways in plants with multi-omics tools and (2) using these enzymes in synthetic biology or crop engineering. The goal of these topics is to highlight areas of research that may need further investment to enhance the successful application of synthetic biology for exploiting the myriad of specialized metabolic pathways.The gut microbiota plays a crucial role in protecting against enteric infection. However, the underlying mechanisms are largely unknown owing to a lack of suitable experimental models. Although most gut commensals are anaerobic, intestinal epithelial cells require oxygen for survival. In addition, most intestinal cell lines do not produce mucus, which provides a habitat for the microbiota. Here, we have developed a microaerobic, mucus-producing vertical diffusion chamber (VDC) model and determined the influence of Limosilactobacillus reuteri and Ruminococcus gnavus on enteropathogenic Escherichia coli (EPEC) infection. Optimization of the culture medium enabled bacterial growth in the presence of mucus-producing T84/LS174T cells. Whereas L. reuteri diminished EPEC growth and adhesion to T84/LS174T and mucus-deficient T84 epithelia, R. gnavus only demonstrated a protective effect in the presence of LS174T cells. Reduced EPEC adherence was not associated with altered type III secretion pore formation. In addition, co-culture with L. reuteri and R. gnavus dampened EPEC-induced interleukin 8 secretion. The microaerobic mucin-producing VDC system will facilitate investigations into the mechanisms underpinning colonization resistance and aid the development of microbiota-based anti-infection strategies.

The population of the European Union is progressively ageing, therefore frailty is becoming a crucial public health issue. In recent years there is a growing interest in a multidimensional concept of frailty, that is not only physical but also psychological and social, in line with a person-centered care.

To measure frailty represents a fundamental step to evaluate the needs for care at both population and individual levels. Of course, to assess frailty in a large population is essential to find short and quick tools able to give reliable results in terms of risk of occurrence of negative events, to stratify older adults according to their frailty level. In this way the most appropriate strategies can be chosen and applied, to delay the functional decline associated to frailty and its consequences, such as hospitalization, institutionalization, low quality of life, and death.

In this review we searched on PubMed for articles about scales assessing frailty with peculiar characteristics published for the eeds for care, but this approach is not common for community care in the EU yet.Zwitterionic hydrogels have attracted a myriad of research interests for their excellent flexibility and biocompatibility as flexible wearable sensors. It is desired to create E-skins that integrate high mechanical strength, sensory sensitivity, and broad adhesion, possessing potential in the fields of intelligent robots and bionic prostheses. In this work, a novel macromolecular cross-linker (MPU) based on waterborne polyurethane (WPU) was designed and applied to synthesize multifunctional conductive hydrogels (PASU-Zn hydrogels). Importantly, in the presence of MPU, the hydrogels exhibited well-balanced mechanical properties (elongation at break 1193%, tensile strength 1.02 MPa, outstanding puncture resistance, and self-recovery abilities). When assembled as wireless strain sensors, PASU-Zn sensors displayed distinguished sensing characteristics to detect mechanotransduction signals of human movements in real-time. Specifically, owing to the dipole-dipole interaction and hydrogen bonding of zwitterions and MPU, the hydrogels have remarkable self-adhesion properties to various surfaces of wood, PDMS, and pigskin, allowing them to stick to skins by themselves without using any adhesive tapes when used. It is deemed that the as-designed zwitterionic hydrogels show great promise for wearable devices and bionic skins.Correction for 'Incorporation of Fmoc-Dab(Mtt)-OH during solid-phase peptide synthesis a word of caution' by Pak-Lun Lam et al., Org. Biomol. Chem., 2022, DOI 10.1039/d2ob00070a.Polyprodrugs with drugs as the structural units have been recognized as promising drug self-delivery systems (DSDSs) for tumor chemotherapy, especially ones in which the drug structural units are linked with both pH- and reduction-cleavable conjugations. However, stable DOX derivatives are released after the acid/reduction co-triggered degradation, exhibiting low antitumor efficacy due to their low solubility. Herein, a novel acid/reduction co-triggered degradable amphiphilic copolyprodrug was designed via the facile polycondensation of an acid-labile dimer (D-DOXADH) and disulfide-containing monomer (DNC) with a PEGylated dimer (D-DOXADH-PEG) as an end-capping reagent. The resultant amphiphilic copolyprodrug (PDOXSS-ADH-PEG) with a high DOX content of 61.1% could easily self-assemble into nanoparticles around 154 nm in size, possessing excellent acid/reduction co-triggered DOX release and enhanced inhibition of tumor growth compared to free DOX towards HepG2 cells but showed good cytocompatibility towards L02 cells.Pyrrolo[2,1-a]isoquinolines occur frequently in a large number of bioactive natural products and pharmaceutically important molecules. The synthesis of pyrrolo[2,1-a]isoquinoline derivatives is an easy and useful way to produce artificial molecules with potential applications. selleck A huge number of excellent methodologies for constructing pyrrolo[2,1-a]isoquinolines have been reported in the last decade. This review summarizes the recent advances in this research field covering from 2011 to 2021.In this paper, we have proposed a novel strategy to combine electrochemical anodization and electropolymerization for the in situ preparation of metal oxide/conductive polymer hybrid electrodes in supercapacitors. The feasibility of such a strategy was further verified by applying it to the iron oxide/polyaniline (Fe3O4/PANI) hybrid electrode material system.The resonance-stabilized 2-methylallyl radical, 2-MA, is considered as a possible intermediate in the formation of polycyclic aromatic hydrocarbons (PAHs) in combustion processes. In this work, we report on its contribution to molecular growth in a high-temperature microreactor and provide mass-selective IR/UV ion dip spectra of the radical, as well as the various jet-cooled reaction products, employing free electron laser radiation in the mid-infrared region. Small (aromatic) hydrocarbons such as fulvene, benzene, styrene, or para-xylene, as well as polycyclic molecules, like (methylated) naphthalene, were identified with the aid of ab initio DFT computations. Several reaction products differ by one or more methyl groups, suggesting that molecular growth is dominated by (de)methylation in the reactor.In consideration of the mounting attention drawn by the ionic liquid cyphos 101 (trihexyl(tetradecyl)phosphonium chloride [P66614][Cl]) in the recovery of rare earth metals and other valuable species from their waste matrices, an effort was made using luminescence spectroscopy to study the detailed liquid-liquid extraction and coordination behavior of Eu(III) using the nitrate form of cyphos 101 (cyphos nitrate [P66614][NO3]) in its undiluted form. Eu(III) complexation with [P66614][NO3] at each stage of the extraction process was investigated using the luminescence spectroscopy technique. Various extraction parameters such as aqueous phase acidity, concentrations of ionic liquid extractant and initial Eu(III) ion, extraction time, experimental temperature, etc. were tuned to discover their impact on the complexation process. The uniqueness of the nitrate ion in ionic liquid was explored by comparing the emission patterns of Eu(III) with [P66614]-based ionic liquids containing different anions. In addition, the affirmative effect of increasing the initial aqueous phase nitrate ion concentration in the coordination process was underscored by comparing the emission patterns in the chloride medium. The luminescence results of the Eu(III)- [P66614][NO3] complex were compared both in unirradiated and irradiated ionic liquid phases. Asymmetry ratio (AR) and lifetime data under each experimental condition were ascertained, thereby revealing the precise nature of complex formation and strength of the metal-solvate species (metal-ligand complex formation) formed. The stripping of the loaded Eu(III) from the [P66614][NO3] phase was established and the results were presented in the form of the emission patterns of Eu(III) in both phases.Depression remains one of the most prevalent psychiatric disorders, and it has been confirmed that it is related to the dysfunction of the microbiota-gut-brain axis. Manipulation of the gut microenvironment by probiotics might improve mental health and prevent stress-related psychiatric disorders. The present study aimed to determine whether Lactobacillus rhamnosus (L. rhamnosus) zz-1 could prevent the occurrence of depression and its potential mechanisms using a mouse model with chronic unpredictable mild stress (CUMS). The results indicated that L. rhamnosus zz-1 intervention ameliorated CUMS-induced depression-like behaviors of mice with reduced body growth rate, lowered sucrose preference, increased immobility time, as well as decreased curiosity and mobility. Moreover, L. rhamnosus zz-1 significantly inhibited hormones released due to hyperactivity of the hypothalamic-pituitary-adrenal (HPA) axis, alleviated CUMS-induced deficits of monoamine neurotransmitters, and increased the expression of brain-derived neurotrophic factor (BDNF) and tyrosine kinase receptor B (TrkB).
