The results suggest that a defective metabolic state might play a role in neurocognitive performance of schizophrenia patients. Glioblastoma multiforme (GBM) is the most common primary malignancy in the adult central nervous, and is characterized by high aggressiveness and a high mortality rate. The high mortality rate is largely due to the development of drug resistance. Temozolomide (TMZ) resistance is considered to be one of the major reasons responsible for GBM therapy failure. CXCL12/CXCR4 has been demonstrated to be involved in cell proliferation, migration, invasion, angiogenesis, and radioresistance in GBM. However, its role in TMZ resistance in GBM is unknown. In this study, we aimed to evaluate the role of CXCL12/CXCR4 in mediating the TMZ resistance to GBM cells and explore the underlying mechanisms. We found that the CXCL12/CXCR4 axis enhanced TMZ resistance in GBM cells. Further study showed that CXCL12/CXCR4 conferred TMZ resistance and promoted the migration and invasion of GBM cells by up-regulating FOXM1. This resistance was partially reversed by suppressing CXCL12/CXCR4 and FOXM1 silencing. Our study revealed the vital role of CXCL12/CXCR4 in mediating the resistance of GBM cells to TMZ, and suggested that targeting CXCL12/CXCR4 axis may attenuate the resistance to TMZ in GBM. Accounting and finance are not typically a core educational offering in medical education. However, for physician leaders and leaders-in-grooming, it is prudent to be familiar with key financial indicators and ratios. The purpose of this review article is to provide fundamental information for emerging radiology physician leaders by describing important financial indicators and ratios, how they are defined and calculated, and, most importantly, how they can be interpreted and utilized for improving practice performance. SUMMARY SENTENCE Understanding and implementing key financial ratios and indicators is important to maintain and improve financial performance in radiology practices. The past decade has witnessed a paradigm shift in cancer therapy owing to the introduction of immune checkpoint inhibitors (ICIs) and it is now commonplace for radiologists to image patients on therapy with these agents. The purpose of this review is to detail the mechanism, radiological manifestations and clinical significance of ICI related toxicities, according to the organ system involved. ICI related toxicities that have known imaging manifestations include colitis, enterocolitis, pancreatitis, hepatitis, endocrine toxicities, pneumonitis, cardiovascular toxicity and musculoskeletal toxicity. These toxicities may be acute, recurrent or chronic in nature. Radiologists must be aware of the imaging features and clinical significance of these toxicities in order to effectively participate in personalized cancer therapy. see more BACKGROUND For adults with attention/hyperactivity disorder (ADHD), research is scarce on their coping with stress (despite studies demonstrating other self-regulation deficits) and their attachment patterns (despite rare research in younger persons with ADHD showing high vulnerability to insecure attachments). Attachment was linked with coping and self-regulation in general populations but not yet in ADHD. This study explored the possible mediational role of attachment patterns in explaining associations between adults' ADHD symptoms and dysregulated coping. METHODS Participants comprised 62 adults (32 females, 30 males) ages 21-40 years (M = 27.60, SD = 4.80) in two groups 31 adults with formally diagnosed ADHD and 31 demographically matched adults without ADHD. Instruments included computerized neuropsychological tests (sustained/executive attention) and self-reports (ADHD, coping, attachment). RESULTS Disorder status was verified via ADHD-symptom self-reports and computerized testing. Preliminary analyses revealed significant intergroup differences on coping strategies and attachment. PROCESS analyses (Hayes, 2013) pinpointed attachment measures' mediating role (especially attachment anxiety) regarding ADHD's association with coping. CONCLUSIONS Significantly more maladaptive attachment and coping outcomes emerged for adults with ADHD than controls. Attachment insecurity's role in mediating ADHD's association with coping was partially supported. Possible unique adaptive value of attachment relationships was discussed for coping with stressors in adulthood with ADHD. Idiopathic pulmonary fibrosis (IPF) is a progressive, life-threatening and interstitial lung disease with the median survival of only 3-5 years. However, due to the unclear etiology and problems in accurate diagnosis, up to now only two drugs were approved by FDA for the treatment of IPF and their outcome responses are limited. Numerous studies have shown that TGF-β is the most important cytokine in the development of pulmonary fibrosis and plays a role through its downstream signaling molecule TGF-binding receptor Smads protein. In this paper, compounds bearing 2(1H)-quinolone scaffold were designed and their anti-fibrosis effects were evaluated. Of these compounds, 20f was identified as the most active one and could inhibit TGF-β-induced collagen deposition of NRK-49F cells and mouse fibroblasts migration with comparable activity and lower cytotoxicity than nintedanib in vitro. Further mechanism studies indicated that 20f reduced the expression of fibrogenic phenotypic protein α-SMA and collagen Ⅰ by inhibiting the TGF-β/Smad dependent pathways and ERK1/2 and p38 pathways. Moreover, compared with the nintedanib, 20f (100 mg/kg/day, p.o) more effectively alleviated collagen deposition in lung tissue and delayed the destruction of lung tissue structure both in bleomycin-induced prevention and treatment mice pulmonary fibrosis models. The immunohistochemical experiments further showed that 20f could block the expression level of phosphorylated Smad3 in the lung tissue cells, which resulted in its anti-fibrosis effects in vivo. In addition, 20f demonstrated good bioavailability (F = 41.55% vs 12%, compare with nintedanib) and an appropriate elimination half-life (T1/2 = 3.5 h), suggesting that 20f may be a potential drug candidate for the treatment of pulmonary fibrosis.
