g., chitosan and Eudragit® S-100) has demonstrated huge promise for colon-specific release of payload. Hence, smartly designed pectin-based multi-particulate carriers, especially in combination with other polymers and/or colon-targeting approaches (e.g., microbial-triggered + pH-triggered or microbial-triggered + pH-triggered + time-release or microbial-triggered + pH-triggered + pressure-based), can be successful colon-specific delivery systems. However, more clinical trials are necessary to bring this idea from bench to bedside.
We investigated the impact of de novo donor-specific anti-human leukocyte antigen antibodies (dnDSAs) on long-term death-censored graft survival and renal allograft rejection in kidney transplant recipients.
The sample for this retrospective cohort study comprised 121 recipients of kidney transplants with negative complement-dependent cytotoxicity crossmatches to their deceased donors. Recipients were divided into two groups dnDSAs+ (n=31) and dnDSAs- (n=90). We evaluated rejection and long-term graft survival rates in the recipients along with pathologic changes in the transplanted kidneys.
DnDSAs were identified in 31/121 patients (25.6%). The graft survival rate in the dnDSAs+ group was 87.1% (27/31) and that of the dnDSAs- group was 97.8% (88/90). The dnDSAs+ group had lower graft survival rates than patients without dnDSAs (p=0.007). There was no difference in the graft survival rates between patients with high DSA mean fluorescence intensity (≥4000) and those with low intensity (<4000) (p=0.669). There was also no difference in the graft survival rates of patients with HLA class I, II, and I+II dnDSAs (p=0.571). The presence of dnDSA in serum was associated with a higher incidence of antibody- and T-cell-mediated rejection (p<0.0001). Banff scores for arterial fibrointimal and arteriolar hyalin, thickening as well as C4d deposition differed for the dnDSAs+ and dnDSAs- groups (p<0.05).
DnDSAs were found to be associated with decreased long-term graft survival rates and increased rejection rates, often accompanied by C4d deposition.

From 2012 to 2013, there was a mass methanol poisoning outbreak in the Czech Republic. Methanol metabolites can cause specific lesions in the basal ganglia, subcortical white matter, and optic nerve. However, long-term sequelae of methanol poisoning on cognitive functioning have not yet been explored. The current study aimed to delineate the cognitive changes observed in methanol poisoning survivors in the seven years since 2012.
We conducted longitudinal research with repeated measurements in 2013, 2015, 2017 and 2019 to evaluate the development of cognitive changes after acute methanol poisoning. A complex neuropsychological battery consisted of tests of global cognitive performance, auditory and visual attention, executive functioning, learning and memory, working memory and language. Motor performance measures and depression scale were also included.
Repeated measures ANOVA of four measurements with post-hoc tests showed a significant decline in the Mini-Mental State Examination (p = 0.007); however, other parameters were not significantly decreasing. In comparison to normative values, the z-scores for each test measure, in the memory domain, in particular, ranged from 43 to 60 % of participants below 1.5 SD. Mild to severe depression levels from the onset of poisoning improved during the seven years, returning to normal in up to 27 % of participants.
In the longitudinal perspective, methanol poisoning survivors manifest progressive global cognitive decline and overall persistent below-average cognitive performance with some improvements in the frequency of depressive symptoms.

Reactive Skin Decontamination Lotion (RSDL), composed of Dekon 139 and 2,3-butanedione monoxime, has been shown highly effective against CWAs and TICs. This systematic review compares RSDL efficacy to other decontaminating agents. Online search engines PubMed, Web of Science, and Embase were explored, and all literature containing quantitative data, comparing RSDL to other decontaminating agents, investigated. Year of publication, type of study (in vitro or in vivo), model (animal or human), toxin tested, and result of each relevant article were recorded. In total, 15 relevant papers, comprising a total of 18 experimental models, were identified. Nine studies concluded that RSDL was the most effective decontaminant tested against the toxin of interest. Four studies concluded that RSDL was not the most effective decontaminant tested against the toxin of interest. The remaining 5 studies concluded RSDL displayed similar efficacy to at least one of the other decontaminating agents tested against the toxin of interest. Verteporfin in vivo There is substantial evidence supporting the efficacy of RSDL as a decontaminating agent. However, there remains to be insufficient data on this important topic, and limitations on the usefulness of current data, when applied to the broad array of potential exposures.Bisphenol F (BPF) is a member of endocrine disrupting chemicals (EDCs). As a substitute of bisphenol A (BPA), BPF is widely used in various consumer products, leading to an increased risk of people's exposure. However, there are few studies on the immunotoxicity and mechanism of BPF. This study aimed to investigate the effect of BPF on the secretion of pro-inflammatory cytokines by macrophages and explore its mechanism. In our study, RAW264.7 macrophages were treated with different concentrations of BPF (0, 5, 10 and 20 μM) for 24 h. The results showed that the secretion of pro-inflammatory cytokines (IL-6, TNF-α and IL-1β) and the production of lactate were increased in a dose-dependent manner. BPFalso led to the activation of the PI3K-AKT signaling pathway. After pretreatment with glycolysis inhibitor (2-DG) and exposure to BPF (20 μM), the secretion of pro-inflammatory cytokines induced by BPF was inhibited. PI3K inhibitor (LY294002) and estrogen receptor (ER) antagonist (ICI 182,780) could also inhibit the above effects induced by BPF (20 μM).
