Thymic small cell carcinoma associated with Lambert–Eaton myasthenic syndrome
We report an extremely rare case of LEMS associated with thymic small cell carcinoma. A 71-year-old man was referred to our institution for a mediastinal tumor and a 2-month history of ptosis, fatigue, and gait disorder. Based on the radiological findings, thymoma associated with LEMS was diagnosed, and extended thymectomy was performed. After surgery, the patient’s symptoms had not improved. Anticholinesterase treatment alleviated his symptoms.
Conclusion: HTX-019 administered by 2-minute injection has a tolerable safety profile in patients with cancer, representing a viable method of HTX-019 administration for CINV prevention. PMID: 31709853 [PubMed - as supplied by publisher]

CONCLUSIONS: EGFR expression is significantly higher in HPV positive IP. Stathmin is expressed by all IP tumour cells. Stathmin was also associated with dysplasia and a trend towards a correlation between stathmin positivity and recurrence was found. Stathmin and EGFR might therefore be considered therapeutic targets. PMID: 31710049 [PubMed - as supplied by publisher]
Conclusions: the early use of IVIG could contribute to an improvement and/or stabilization of visual symptoms in this patient group due to its rapid effect and lower profile of adverse effects when administered with chemotherapy. PMID: 31710513 [PubMed - as supplied by publisher]

Page, Adam FrankelAbstractProtein arginine N-methyltransferases (PRMTs) are a family of 9 enzymes that catalyze mono- or di-methylation of arginine residues using S-adenosyl-L-methionine (SAM). Arginine methylation is an important post-translational modification that can regulate the activity and structure of target proteins. Altered PRMT activity can lead to a variety of health issues including neurodevelopmental disease, autoimmune disorders, cancer, and cardiovascular disease. Thus, developing a robust mechanistic ...
Abstract Despite the presence of methods evaluating drug resistance during chemotherapies, techniques, which allow for monitoring the degree of drug resistance in early chemotherapeutic stage from single cells in their native microenvironment, are still absent. Herein, we report an analytical approach that combines single cell mass spectrometry (SCMS) based metabolomics with machine learning (ML) models to address the existing challenges. Metabolomic profiles of live cancer cells (HCT-116) with different levels (i.e., no, low, and high) of chemotherapy-induced drug resistance were measured using the Single-probe S...
Abstract Platelet-derived growth factor-BB (PDGF-BB) is currently used as a biomarker protein for cancer early diagnosis and clinical treatment. Herein, we reported a robust and enzyme-free strategy based on aptamer recognition and proximity-induced entropy-driven circuits (AR-PEDC) for homogeneous and rapid detection of platelet-derived growth factor BB (PDGF-BB) without any washing steps or thermocycling. The proximity probes specifically recognize target protein to form the completed trigger (CT). Then, the CT reacts with three-strand complex to form intermediate, which subsequently binds to fuel strand to rele...
