AIM2 immunoreactivity of the PSCI group was primarily co-localized with Iba-1 (microglial marker) and CD31 (endothelial cell marker) immunoreactivities but not NeuN (neuronal marker) and GFAP (astrocyte marker) immunoreactivities, suggesting that microglia or endothelial cell-induced AIM2 production mediated PSCI pathogenesis. Additionally, inflammasome-induced pyroptosis might contribute to acute and chronic neuronal death after stroke. AIM2 knockout (KO) and Ac-YVAD-CMK-induced caspase-1 inhibition in mice significantly improved cognitive function and reversed brain volume in the hippocampus relative to those in stroke mice. Conclusively, AIM2 inflammasome-mediated inflammation and pyroptosis likely aggravated PSCI; therefore, targeting and controlling AIM2 inflammasome could potentially treat PSCI. BACKGROUND Adverse childhood experiences (ACEs) have long been known to be related to poorer health across the life course. Previous studies typically relied on cumulative risk scores or individual adversities measured through retrospective self-reports. However, these approaches have important limitations. Cumulative risk scores assume equal weighting of adversities and the single adversity approach ignores the high probability that adversities co-occur. In contrast, latent class analysis (LCA) offers an alternative approach to operationalise ACEs that respects the clustering of adversities and may identify specific patterns of ACEs important for health outcomes. Furthermore, prospective and retrospective reports of ACEs show poor agreement. Therefore, it is important to compare findings based on prospective and retrospective measures in the same individuals. Despite an increasing number of studies applying LCA to ACEs data, no studies have yet simultaneously investigated LCA to cumulative risk and single adlatent classes were identified in the prospective data - 'Low ACEs' (95.7%), 'Household dysfunction' (2.8%) and 'Parental loss' (1.5%) which were related to increased inflammation in mid-life, as were high ACE scores and individual measures of offending, death, divorce, physical neglect and family conflict. Four latent classes were identified in the retrospective data - 'Low ACEs', 'Parental mental health and substance misuse', 'Maltreatment and conflict' and 'Polyadversity.' The latter two (5.2%) were related to raised inflammation in mid-life, as was a retrospective ACE score of 4+ (8.3%) and individual measures of family conflict, psychological and physical abuse, emotional neglect and witnessing abuse. CONCLUSIONS Specific ACEs or ACE combinations might be important for chronic inflammation. LCA is an alternative approach to operationalising ACEs data but further research is needed. Patient to patient variability is one of the issues when administering medications to individuals with different health conditions, pharmacokinetic, age, fitness, gender, and race. This requires introducing smart and personalised drug delivery systems with controlled release profile manufactured using novel approaches. Additive manufacturing (AM) provides opportunities such as full customisation, design freedom, and on-site manufacturing, and materials recycling. As a result, the academic and industrial demand for additive manufacturing for drug delivery has been continuously increasing and showing impressive results for a wide range of products. This paper provides an extensive overview of AM technologies and their applications for drug delivery. The review discusses AM technologies including their working principles, processed materials, as well as current progress in drug delivery to produce personalized dosages for every patient with controlled release profile. AM potentials, industrial scale, and challenges are investigated with regards to practice and industrial applications. The paper covers novel possibilities of AM technologies and their pharmaceuticals applications, which indicate a promising healthcare future. Hypoxia is a characteristic feature of various ischemic diseases, including cancer. This study describes the development of glycol chitosan nanoparticles, hydrophobically modified with 4-nitrobenzyl chloroformate and folic acid (FA), that can specifically release drugs under hypoxic conditions. This hypoxia-responsive glycol chitosan nanoparticle conjugated with FA (HRGF) possesses tumor-targeting properties by virtue of conjugated FA and is able to release drugs in a nitroreductase (NTR)-dependent manner because its structure is cleaved by NTR under hypoxic conditions. HRGF nanoparticles showed improved in vivo cancer-targeting ability compared with HRG nanoparticles without FA. In vitro drug release profiles revealed that doxorubicin (DOX)-loaded HRGF (D@HRGF) nanoparticles showed rapid release under hypoxia conditions than normoxic conditions. In vitro cytotoxicity tests and microscopic observations showed that D@HRGF nanoparticles were more toxic towards hypoxic cells than normoxic cells, and that the release of DOX was more effective in hypoxia than normoxia. In vivo, D@HRGF nanoparticles showed more effective antitumor activity in mice compared with D@HRG and free DOX. Collectively, these results show that HRGF nanoparticles function as an effective drug-delivery system in hypoxic conditions. Moreover, these hypoxia-responsive nanoparticles would be effective not only in cancer, but also in other ischemic diseases. Gold nanoparticle (AuNP) interaction with the blood compartment as a function of their charge and the binding energy of their surface ligand was explored. Citrate, polyallylamine and cysteamine stabilized AuNP along with dihydrolipoic acid and polyethylene glycol capped AuNP were synthesized and fully characterized. Their interactions with model proteins (human albumin and human fibrinogen) were studied. Complexes formed between AuNP and protein revealed several behaviors ranging from corona formation to aggregation. Protein fluorescence quenching as a function of temperature and AuNP concentration allowed the determination of the thermodynamic parameters describing these interactions. The hemolysis induced by AuNP was also probed an increasing or a decreasing of hemolysis ratio induced by AuNP was observed as of function of protein corona formation. Taken together, our results drew up a composite sketch of an ideal surface ligand for blood compatible AuNP. This capping agent should be strongly bound to the gold core by one or more thiol groups and it must confer a negative charge to the particles. V.Low rates of adult patient participation have been a persistent problem in cancer clinical trials and have continued to be a barrier to efficient drug development. The routine use of significant exclusion criteria has contributed to this problem by limiting participation in studies and creating significant clinical differences between the study cohorts and the real-world cancer patient populations. These routine exclusions also unnecessarily restrict opportunities for many patients to access potentially promising new therapies during clinical development. Multiple efforts are underway to broaden eligibility criteria, allowing more patients to enroll in studies and generating more robust data regarding the effect of novel therapies in the population at large. Focusing specifically on lung cancer as an example, a multistakeholder working group empaneled by the LUNGevity Foundation identified 14 restrictive and potentially outdated exclusion criteria that appear frequently in lung cancer clinical trials. As a part of the project, the group evaluated data from multiple recent lung cancer studies to ascertain the extent to which these 14 criteria appeared in study protocols and played a role in excluding patients (screen failures). The present report describes the working group's efforts to limit the use of these routine exclusions and presents clinical justifications for reducing the use of 14 criteria as routine exclusions in lung cancer studies, potentially expanding trial eligibility and improving the generalizability of the results from lung cancer trials. Transmembrane member 16A (TMEM16A) encoded Ca2+-activated Cl- channels were found to be involved in tumorigenesis. Previous studies suggest the effect of TMEM16A gene amplification on tumorigenic proliferation is exerted through its channel function. TMEM16A-specific and potent small molecule inhibitors have been proposed to potentially be useful for the treatment of cancer. Thus, we screened six analogues of avermectin for their inhibitory activities on TMEM16A mediated currents. A whole-cell patch technique was used to record the currents. The IC50 and Emax values for TMEM16A inhibition of five tested avermectins (avermectin B1, ivermectin, doramectin, selamectin, and moxidectin) were 0.15-1.32 μM and 65-87 %, respectively. In addition, these avermectins significantly inhibited endogenous TMEM16A mediated currents and thus, the proliferation, migration, inducing apoptosis of LA795 cancer cells. Eprinomectin (4"-(acetylamino)-4"-deoxy-avermectin B1) and two other important macrolides (erythromycin and azithromycin), which have minimal or no TMEM16A inhibitory effects, were used as negative control drugs. These drugs were found to have limited effects on the proliferation, migration, and apoptosis of LA795 cells. Selleck ALK inhibitor Finally, avermectin B1 and ivermectin dramatically inhibited the growth of xenograft tumors in mice. These data demonstrate that avermectins are novel TMEM16A inhibitors and are potentially useful in specific cancer therapies. These findings also provide a new opportunity to develop TMEM16A modulators. The aim of this systematic review and dose-response meta-analysis was to determine the effect of Nigella Sativa (N.S) supplementation on liver and kidney parameters. We searched PubMed, Scopus, ISI Web of Science, Cochrane central register for controlled trials and Google Scholar from database inception to April 2019 for relevant controlled trials. Mean differences and standard deviations for each outcome were pooled using a random-effects model and a dose-response analysis was performed using a fractional polynomial model. Quality of evidence was evaluated using Cochrane Collaboration Risk of Bias tool and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology. Nineteen trials (n = 1295 participants) were included in the meta-analysis. We observed that N.S supplements had significant reducing effects on alkaline-phosphatase (ALP) [9 trials, n = 710 participants, weighted mean difference (WMD)= -10.825; 95%CI -19.658, -1.992 U/L; P = 0.016; I2 = 75.7 %; P-heterogeneity = 0.0icipants, WMD= -1.016; 95% CI -1.760, -0.273 U/L; P = 0.007; I2 = 87.7%; P-heterogeneity = 0.000). Our data suggested that N.S supplementation had significant impacts on liver and kidney parameters leading to a decrease in ALP and BUN levels. Longer duration of intervention and normal daily dosages of N.S supplements led to significant reductions in ALP and AST concentrations, respectively, while higher daily dosages increased BUN levels. Hence, in spite of favorable impacts of N.S supplements on liver and kidney parameters, due to the herbal nature of N.S, more studies with high-quality, large-scale, long-term intervention and precise baseline characteristics are needed to assess the exact effective dose, duration and efficacy of N.S supplementation on kidney and liver parameters.
