Article Abstract
Myasthenia gravis (MG) is the most common disorder of neuromuscular transmission and is a heterogeneous disorder generally caused by auto-antibody to the nicotinic acetylcholine receptor. The current study presented a rare case of MG that occurred a long time after surgical resection of lung cancer. A 58-year-old man with lung adenocarcinoma underwent upper lobectomy and mediastinal lymph node dissection. Severe myasthenic symptoms began 7 years after the operation, and emergent mechanical ventilation was needed because of myasthenic crises. Levels of serum anti-acetylcholine receptor antibody were high and typical decremental responses to repetitive stimulation on electromyography were observed. Appropriate therapies for a severe acute condition were performed, and MG has been controlled for 6 years since then. There is no recurrence of lung cancer or appearance of thymoma. In conclusion, although very rare, physicians should be aware of MG as a potential comorbidity developing in patients with a history of lung cancer.

A Mg(OTf)-catalyzed asymmetric Michael addition/cyclization cascade reaction between 3-isothiocyanato oxindoles and 2-arylidene-1,3-indanediones has been developed. This transformation provides an efficient and concise approach to biologically important bispiro[indanedione-oxindole-pyrrolidinyl]s under mild conditions in good to excellent yields (70-99% yields) with moderate to good stereoselectivities (up to 99% and >95:5 d.r.

Introduction: Immunosenescence remodels immune functions and was first described with aging. It is present in 25% of cancer patients but has also been described in patients with Immune-mediated inflammatory diseases (IMIDs). This study aims at quantifying cells exhibiting a phenotype of senescence in CD4+ (T4sen) and CD8+ (T8sen) T cells, analyzing its potential drivers and the effect of anti-TNF treatment in a prospective cohort of patients with rheumatoid arthritis (RA), spondyloarthritis (SpA) and Sjögren disease (SjD).

Objectives: Bladder cancer is a common malignancy with high incidence and poor prognosis. N-methyladenosine (mA) modification is widely involved in diverse physiological processes, among which the mA recognition protein YTH N-methyladenosine RNA binding protein F2 (YTHDF2) plays a crucial role in bladder cancer progression. This study aims to elucidate the molecular mechanism by which O-linked -acetylglucosamine (O-GlcNAc) modification of YTHDF2 regulates its downstream target, period circadian regulator 1 (), thereby promoting bladder cancer cell proliferation.

Objectives: Non-small cell lung cancer (NSCLC) is associated with poor prognosis, with 30% of patients diagnosed at an advanced stage. Mutations in the and genes are important prognostic factors for NSCLC, and targeted therapies can significantly improve survival in these patients. Although tissue biopsy remains the gold standard for detecting gene mutations, it has limitations, including invasiveness, sampling errors due to tumor heterogeneity, and poor reproducibility.

Aims: We aimed to analyze CD63, a cell surface protein that has been associated with tumor aggressiveness in several cancers, including breast, colorectal, and lung cancer, as well as melanoma, in prostate cancer.
Methods: CD63 expression was analyzed immunohistochemically in a cohort of primary prostate cancers from 281 patients. The results were correlated with clinico-pathologic parameters, including biochemical recurrence.
