Herein, the recent progress of physicochemical properties and surface modification strategies of GO for its application as both carriers and adjuvants is reviewed. STATEMENT OF SIGNIFICANCE Due to its unique physicochemical properties, graphene oxide is widely employed in medicine for purposes of photothermal treatment of cancer, drug delivery, antibacterial therapy, and medical imaging. Our work describes the surface modification of graphene oxide and for the first time summarizes that functionalized graphene oxide serves as a vaccine carrier and shows significant adjuvant activity in activating cellular and humoral immunity. In the future, it is expected to be introduced into vaccine research to improve the efficacy of vaccines.The Dunning-Kruger Effect refers to a common failure of metacognitive insight in which people who are incompetent in a given domain are unaware of their incompetence. This effect has been found in a wide range of tasks, raising the question of whether there is any 'special' domain in which it is not found. One plausible candidate is face perception, which has sometimes been thought to be 'special'. To test this possibility, we assessed participants' insight into their own face perception abilities (self-estimates) and those of other people (peer estimates). We found classic Dunning-Kruger Effects in matching tasks for unfamiliar identity, familiar identity, gaze direction, and emotional expression. Low performers overestimated themselves, and high performers underestimated themselves. Interestingly, participants' self-estimates were more stable across tasks than their actual performance. In addition, peer estimates revealed a consistent egocentric bias. High performers attributed higher accuracy to other people than did low performers. We conclude that metacognitive insight into face perception abilities is limited and subject to systematic biases. Our findings urge caution when interpreting self-report measures of face perception ability. They also reveal a fundamental source of uncertainty in social interactions.Aim The aim of this study was to improve the therapeutic index of chemotherapeutic drugs on glioblastoma cells through an improved co-drug delivery system. Materials and methods Methotrexate (MTX) and paclitaxel (PTX) were co-loaded into poly (lactic-co-glycolic acid) nanoparticles (PLGA NPs) coated with polyvinyl alcohol (PVA) and Poloxamer188 (P188). Key findings The mean size of the NPs was about 212 nm, with a zeta potential of about -15.7 mV. Encapsulation efficiency (EE%) and drug loading (DL%) were determined to be 72% and 4% for MTX and 85% and 4.9% for PTX, respectively. The prepared NPs were characterized by differential thermal analysis (DTA) and thermogravimetric analysis (TGA). Moreover, an in vitro sustained release profile was observed for both drug loaded PLGA NPs. Glioblastoma cellular uptake of the NPs was confirmed by fluorescence microscopy and cell survival rate was investigated through the 3-(4,5-dimethyl thiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) method after 48 h of incubation showing IC50 values of 24.5 μg·mL-1 for PTX and 9.5 μg·mL-1 for MTX for the MTX/PTX co-loaded PLGA nanoparticles coated with PVA/P188 (Co-2 NPs). Apoptosis and necrosis were also studied via flow cytometry, the lactate dehydrogenase (LDH) assay and the amount of anti-apoptotic protein (Bcl-2) expression. Blood compatibility of the co-delivery of PTX and MTX loaded PLGA NPs was investigated using a hemolysis method as well. Significance The co-delivery of PTX and MTX loaded PLGA NPs is promising for the treatment of glioblastoma compared to their respective free drug formulations and, thus, should be further investigated.Aims The regulation of the Ras-ERK pathway is the crucial point in pancreatic carcinogenesis, and the Ras kinase is an essential regulatory upstream signal molecule of the ERK1/2 pathway. H3K9ac is a vital histone modification, but its specific role in pancreatic cancer remains unclear. This research aims to study whether the modification level of H3K9ac can regulate the characteristic phenotype of the pancreatic cancer cells by affecting the downstream expression, proliferation, migration, and other related genes. Main methods The RasG12V/T35S were used to transfect pancreatic cancer cells, and the levels of phosphorylated ERK1/2 and H3K9ac were detected by western blotting. The colony formation assay, transwell assay, and chromatin immunoprecipitation assay were used to study cell viability, migration, and the downstream genes of the ERK1/2 pathway. Key findings The results showed that Ras ERK1/2 reduced H3K9ac expression in ASPC-1 cells, and H3K9ac significantly repressed the viability of cells, colony formation, and ASPC-1 cell movement induced by Ras ERK1/2. Besides, HDAC1 silencing increased H3K9ac expression, and changed the effect of Ras ERK1/2 on ASPC-1 cells proliferation, its movement, and mRNAs of ERK1/2 downstream genes. Moreover, Ras ERK1/2 inhibited H3K9ac expression by the degradation of PCAF via MDM2. Significance Ras ERK1/2 promotes pancreatic carcinogenesis cell movement, through down-regulating H3K9ac via MDM2 mediated PCAF degradation.Resveratrol has the ability to promote functional recovery after sciatic nerve crush injury (SNCI), though the mechanism through which this occurs in not fully understood. Resveratrol can promote autophagy, a key process in Wallerian degeneration; thus, we hypothesized that resveratrol could promote recovery from SNCI by promoting Schwann cell autophagy and acceleration of Wallerian degeneration. click here Motor function recovery was assessed by calculating Sciatic Function Indexes (SFIs) at days 7, 14, 21, 28 post SNCI. Autophagy and myelin clearance were assessed by microtubule-associated protein light chain 3B (LC3B) and myelin protein zero (MPZ) immunofluorescence and Western blot analysis on the fourth day after SNCI. The autophagy of Schwann cells following resveratrol administration was quantified by immunofluorescence in RSC96 cells. Immunofluorescence and Transmission electron microscopy (TEM) were also used in Resveratrol treated sciatic nerve four days post-SNCI to find LC3B positive areas and typical double membrane structures represent for autophagy.
