Cancer immunity is dependent on dynamic interactions between T cells and dendritic cells (DCs). Polymer-based nanoparticles target DC receptors to improve anticancer immune responses. In this paper, DC surface receptors and their specific coupling natural ligands and antibodies are reviewed and compared. Moreover, reaction mechanisms are described, and the synergistic effects of immune adjuvants are demonstrated. Also, extracellular-targeting antigen-delivery strategies and intracellular stimulus responses are reviewed to promote the rational design of polymer delivery systems., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier B.V.

Psilocybin and its active metabolite psilocin are hallucinogenic serotonergic agonists with high affinity for several serotonin receptors. In addition to underlying the hallucinogenic effects of these compounds, serotonin receptor activation also has important effects on decision-making and goal-directed behaviors. The impact of psilocybin and psilocin on these cognitive systems, however, remains unclear. This study investigated the effects of psilocybin treatment on decision-making and motivation in healthy male and female rats. We compared probability and delay discounting performance of psilocybin treated (1 mg/kg) to vehicle rats (n = 10/sex/group), and further assessed motivation in each group using a progressive ratio task. We also confirmed drug action by assessing head twitch responses after psilocybin treatment (1 mg/kg). Results from this study demonstrated that exposure to 1 mg/kg psilocybin did not affect decision-making in the probability and delay discounting tasks and did not reduce response rates in the progressive ratio task. However, psilocybin treatment did cause the expected increase in head twitch responses in both male and female rats, demonstrating that the drug was delivered at a pharmacologically relevant dosage. Combined, these results suggest that psilocybin may not impair or improve decision-making and motivation. Considering recent interest in psilocybin as a potential fast-acting therapeutic for a variety of mental health disorders, our findings also suggest the therapeutic effects of this drug may not be mediated by changes to the brain systems underlying reward and decision-making. Finally, these results may have important implications regarding the relative safety of this compound, suggesting that widespread cognitive impairments may not be seen in subjects, even after chronic treatment., Competing Interests: Competing Interests JAJ, WJG, and MSM are co-inventors on several related patent applications.

Recycling of agro-wastes presents a great economic and ecologic value. In this study, TEMPO-oxidized nanofibrillated cellulose (TONFC) originating from sugarcane bagasse pulp was exploited in regenerative medicine. TONFC in combination with glucosamine HCl (G) were used to prepare a 3D aerogel implant loaded with rosuvastatin as an integrative approach for extraction-socket healing. Comparing the prepared devices, aerogel composed of TONFC: G (4:1 wt ratio) had the best mechanical properties and integrity. Strontium borate-based bioactive ceramic particles were prepared and characterized for crystal structure, shape, porosity, and zeta potential. The particles had a crystalline diffraction pattern relative to Sr 3 B 2 O 6 , and they were rod in shape with nanopores with a zeta potential value of -16 mV. The prepared bioactive ceramic (BC) was then added in different concentrations (3 or 6% w/w) to the selected aerogel implant. The BC had a concentration-dependent effect on the aerogel properties as it ameliorated its mechanical performance (compressive strength = 90 and 150 kPa for 3 and 6%, respectively) and retarded drug release (mean release time = 2.34 and 3.4 h for 3 and 6%, respectively) (p < 0.05). The microphotograph of the selected aerogel implant loaded with BC showed a rough surface with an interconnective porous structure. During cell biology testing, the selected implant loaded with the lower BC concentration had the highest ability to increase MG-63 cells proliferation. In conclusion, TONFC is a promising material to formulate rosuvastatin-loaded aerogel implant with the aid of glucosamine and bioactive ceramic for dental socket preservation., (Copyright © 2022 Elsevier B.V.

The preparation of a cationic beta-cyclodextrin polymer (CPbetaCD) and its complexes with butylparaben and triclosan were reported in this paper. FT-IR and 2D 1H-1H gCOSY NMR spectra confirmed that the antibiotics could be included inside of the lipophilic cavities of CPbetaCD. The formation of complexation of CPbetaCD with the antibiotics significantly improved the water solubility. The solubility of the antibiotics linearly increased with the concentration of CPbetaCD, and the values of the association constant K1:1 of the butylparapben/CPbetaCD and triclosan/CPbetaCD complexes were 3800 and 3082 M(-1), respectively. The results also suggested that it was easier for butylparaben, which had relative smaller molecular size, to form the complexes with CPbetaCD than triclosan. Due to the targeting effect after the complexation with CPbetaCD, the antimicrobial activity of butylparaben can be significantly improved. Meanwhile, this improvement effect was not obvious for triclosan.

A dot-blot hybridization assay for serum B19 DNA is described using a non-radioactive (digoxigenin) M13 single-stranded DNA probe. The assay is sensitive (0.3 pg of B19 DNA) and has several advantages over similar assays which use radioactive or non-radioactive labelled plasmid probe for the routine detection of B19 DNA in sera.
