Establishment of a non-small-cell lung cancer-liver metastasis patient-derived tumor xenograft model for the evaluation of patient-tailored chemotherapy. Biosci Rep. 2019 Jun 20;: Authors: Yang X, Meng G Abstract In order to optimize patient-tailored chemotherapy, a non-small-cell lung cancer (NSCLC)-liver metastasis patient-derived tumor xenograft (PDTX) model is developed. Computed tomography (CT)-guided NSCLC percutaneous biopsy was subcutaneously inoculated into the flank of non-obese diabetic/severe combined immunodeficiency (NOD/SCID) female mice (PDTX F1) and allowed to reach 500 mm3 volume. Then, the tumors were re-transplanted into Balb/c nude mice and liver metastasis was confirmed (PDTX F2), which were further assigned into doxorubicin (DOX), docetaxel (DTX), and nontreatment control group. H&E staining and Keratin 20 (CK20) staining were applied to determine the consistency of PDTX models and primary tumors. Tumor growth curve, body weight, and the expression of p65 nuclear factor (NF)-κB and the secretion of interferon (IFN)-γ were investigated. The Successive transplant procedure can induce the NSCLC-liver metastasis PDTX model, and morphological and structural characteristics of PDTX models (F2) were in accordance with primary tumors. DOX and DTX could delay tumor growth, activate the NF-κB pathway, and promote IFN-γ secretion in the PDTX models. The NSCLC-liver metastasis PDTX model is established and provides a po...

ConclusionThe proposed multiparametric MRI-based SLICs+MTh method performs noninvasive assessment of NACT response in osteosarcoma that may improve cancer treatment monitoring, planning, and overall prognosis.Key Points• The simple linear iterative clustering supervoxels and Otsu multithresholding-based technique (SLICs+MTh) successfully estimates the proportion of necrosis, viable tumor, and edema in osteosarcoma in the course of chemotherapy.• The proposed technique is noninvasive and uses multiparametric MRI to measure necrosis as an indication of anticancer treatment response.• SLICs+MTh-based necrosis w...

ConclusionsThe e-ASPECTS software generates robust values for e-ASPECTS and acute infarct volumes when using ST ≤ 4 mm with ST = 1 mm yielding the best performance for predicting baseline stroke severity and clinical outcome after 90 days.Key Points•Clinical utility of automatically derived ASPECTS from computed tomography scans was shown in patients with acute ischemic stroke and treatment with mechanical thrombectomy.•Thin slices (=  1 mm) had the highest clinical utility in comparison with thicker slices (2–10 mm) by having the strongest correlation...

CONCLUSIONS: The average patient is middle aged (often male) with a history of subacute back pain, sometimes presenting fever and/or neurological damage on diagnosis. Acute phase reactants are frequently raised. Diabetes mellitus, endocarditis and immunosuppressed patients may have the worst chance of a good outcome, therefore these patients should be more carefully managed (always try to obtain an imaging-guided biopsy, correct antibiotic treatment, and a functional and clinical follow-up).

In conclusion, the concept of an epigenetic clock is compelling, but caution should be taken in interpreting associations with age acceleration. Association tests of age acceleration should include age as a covariate.

Conclusion and Perspectives The IL-6/JAK/STAT signaling cascade plays a dominant role in skeletal muscle pathophysiology. IL-6 autocrine, paracrine, and endocrine functions assign to its downstream effectors pivotal importance in skeletal muscle-wasting-associated diseases and other multiple system diseases where muscle acts in communication with other organs. Targeting the components of the JAK/STAT pathway recently emerged as a strategic approach for the treatment of inflammatory diseases and human cancer. This review highlights the opposite outcomes on muscle biology caused by the amount of local and systemic release ...

ConclusionsCirculating formate is reduced in HER2+ breast cancer, non-small cell lung cancer and highly obese patients relative to healthy controls. Further studies are required to determine the relevance of these observations in other cancer types and diseases.

Conclusion Most head and neck pathologies show a broad cellular heterogeneity making it difficult to achieve an accurate diagnosis and efficient treatment (Graf and Zavodszky, 2017; Lo Nigro et al., 2017). Single cell analysis of circadian omics (Lande-Diner et al., 2015; Abraham et al., 2018), may be a crucial tool needed in the future to fully understand the circadian control of head and neck diseases. It becomes more obvious that there is only a small genetic component but a largely unknown epigenetics and/or environmental component for most of the head and neck pathologies (Moosavi and Motevalizadeh Ardekani, 2016; He...
