To achieve improved drug delivery efficiency to hepatocellular carcinoma (HCC), biodegradable poly (ethylene glycol)-poly (lactic-co-glycolic acid) (PEG-PLGA) nanoparticles (NP), surface-modified with SP94 peptide, were designed for the efficient delivery of cryptotanshinone to the tumor for the treatment of HCC. Cryptotanshinone NP and SP94-NP were prepared by using nanoprecipitation. VE-821 datasheet The physicochemical and pharmaceutical properties of the NP and SP94-NP were characterized, and the release kinetics suggested that both NP and SP94-NP provided continuous, slow release of cryptotanshinone for 48 h. The in vitro cellular experiment demonstrated that SP94-NP significantly enhanced the cellular uptake of cryptotanshinone and induced high cytotoxicity and cellular apoptosis of hepatocellular carcinoma (HepG2) cells. The in vivo detecting results of targeting effect using the Cy5.5 probe evidenced that SP94-NP showed an accumulation in tumor more efficiently than that of unconjugated ones. Meanwhile, SP94-NP exhibited the smallest tumor size than other groups and showed no toxicity to body. The results of this study provide a promising nanoplatform for the targeting of HCC.Faces are processed in a network of areas within regions of the ventral visual stream. However, familiar faces typically are characterized by additional associated information, such as episodic memories or semantic biographical information as well. The acquisition of such non-sensory, identity-specific knowledge plays a crucial role in our ability to recognize and identify someone we know. The occipital face area (OFA), an early part of the core face-processing network, is recently found to be involved in the formation of identity-specific memory traces but it is currently unclear if this role is limited to unimodal visual information. The current experiments used transcranial magnetic stimulation (TMS) to test whether the OFA is involved in the association of a face with identity-specific semantic information, such as the name or job title of a person. We applied an identity-learning task where unfamiliar faces were presented together with a name and a job title in the first encoding phase. Simultaneously, TMS pulses were applied either to the left or right OFA or to Cz, as a control. In the subsequent retrieval phase, the previously seen faces were presented either with two names or with two job titles and the task of the participants was to select the semantic information previously learned. We found that the stimulation of the right or left OFA reduced subsequent retrieval performance for the face-associated job titles. This suggests a causal role of the OFA in the association of faces and related semantic information. Furthermore, in contrast to prior findings, we did not observe hemispherical differences of the TMS intervention, suggesting a similar role of the left and right OFAs in the formation of the visual-semantic associations. Our results suggest the necessity to reconsider the hierarchical face-perception models and support the distributed and recurrent models.Personality factors have been associated with Alzheimer's disease (AD) and dementia, but they have not been examined against markers of regional brain glucose metabolism (a primary measure of brain functioning) in older adults without clinically diagnosed cognitive impairment. The relationship between personality factors derived from the five-factor model and cerebral glucose metabolism determined using positron emission tomography (PET) with [18F]-2-fluoro-2-deoxy-D-glucose (18F-FDG-PET) was examined in a cohort of 237 non-demented, community-dwelling older adults aged 60-89 years (M ± SD = 73.76 ± 6.73). Higher neuroticism and lower scores on extraversion and conscientiousness were significantly associated with decreased glucose metabolism in brain regions typically affected by AD neuropathological processes, including the hippocampus and entorhinal cortex. Furthermore, while there were significant differences between apolipoprotein E (APOE) ε4 allele carriers and non-carriers on 18F-FDG-PET results in the in delay or ideally preventing the onset of the cognitive impairment.Retinitis pigmentosa (RP) is a neurodegenerative disorder that causes irreversible vision loss in over 1.5 million individuals world-wide. The genetic heterogeneity of RP necessitates a broad therapy that is able to provide treatment in a gene- and mutation- non-specific manner. In this study, we identify the therapeutic benefits of metabolic reprogramming by targeting pyruvate kinase M2 (PKM2) in a Pde6β preclinical model of RP. The genetic contributions of PKM2 inhibition in retinal degeneration were evaluated through histology and electroretinogram (ERG) followed by a statistical analysis using a linear regression model. Notably, PKM2 ablation resulted in thicker retinal layers in Pde6β-mutated mice as compared to the controls, suggesting greater photoreceptor survival. Consistent with these anatomical findings, ERG analyses revealed that the maximum b-wave is on average greater in Pkm2 knockout mice than in mice with intact Pkm2, indicating enhanced photoreceptor function. These rescue phenotypes from Pkm2 ablation in a preclinical model of RP indicate that a metabolome reprogramming may be useful in treating RP.PURPOSE Understanding the supportive care and unmet care needs of patients with melanoma is essential for informing the development or evaluation of supportive care services and interventions for patients with melanoma. METHODS Three electronic databases (CINAHL, Medline and PsycINFO) were searched from 2000 to November 2019 to identify eligible quantitative and qualitative studies. The quality of evidence was assessed using the Mixed Methods Appraisal Tool. RESULTS Fourteen studies (10 quantitative, three qualitative and one mixed-methods) were included. Informational care and unmet needs were the most commonly reported in patients with melanoma, followed by psychological, then social and physical. Findings were consistent between quantitative and qualitative studies; however, findings from qualitative data complimented those from quantitative data by providing more depth and insight into the prevalence, effects and associations of the different care needs. Patients' care and unmet needs were found to also be present all throughout their cancer journey and vary according to the stage throughout.
