Patients with chronic lymphocytic leukemia (CLL) who develop Richter transformation (RT) have a poor prognosis when treated with chemoimmunotherapy regimens used for de novo diffuse large B-cell lymphoma. Venetoclax, a BCL2 inhibitor, has single-agent efficacy in patients with RT and is potentially synergistic with chemoimmunotherapy. In this multicenter, retrospective study, we evaluated 62 patients with RT who received venetoclax-based treatment outside of a clinical trial, in combination with a Bruton tyrosine kinase inhibitor (BTKi; n=28), rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone (R-CHOP) (n=13), or intensive chemoimmunotherapy other than R-CHOP (n=21). The best overall and complete response rates were 36%/25%, 54%/46%, and …

We describe a strategy that combines histologic and molecular mapping that permits interrogation of the chronology of changes associated with cancer development on a whole-organ scale. Using this approach, we present the sequence of alterations around RB1 in the development of bladder cancer. We show that RB1 is not involved in initial expansion of the preneoplastic clone. Instead, we found a set of contiguous genes that we term "forerunner" genes whose silencing is associated with the development of plaque-like field effects initiating carcinogenesis. Specifically, we identified five candidate forerunner genes (ITM2B, LPAR6, MLNR, CAB39L, and ARL11) mapping near RB1. Two …

Abscisic acid (ABA) plays a crucial role in promoting plant stress resistance and seed dormancy. However, how ABA regulates rice quality remains unclear. This study identifies a key transcription factor SLR1-like2 (SLRL2), which mediates the ABA-regulated amylose content (AC) of rice. Mechanistically, SLRL2 interacts with NF-YB1 to co-regulate Wx, a determinant of AC and rice quality. In contrast to SLR1, SLRL2 is ABA inducible but insensitive to GA. In addition, SLRL2 exhibits DNA-binding activity and directly regulates the expression of Wx, bHLH144 and MFT2. SLRL2 competes with NF-YC12 for interaction with NF-YB1. NF-YB1 also directly represses SLRL2 transcription. Genetic validation …

1,4-naphthoquinones (NQs) catalytically oxidize H2S to per- and polysufides and sulfoxides, reduce oxygen to superoxide and hydrogen peroxide, and can form NQ-SH adducts through Michael addition. Here, we measured oxygen consumption and used sulfur-specific fluorophores, liquid chromatography tandem mass spectrometry (LC-MS/MS), and UV-Vis spectrometry to examine H2S oxidation by NQs with various substituent groups. In general, the order of H2S oxidization was DCNQ ~ juglone > 1,4-NQ > plumbagin >DMNQ ~ 2-MNQ > menadione, although this order varied somewhat depending on the experimental conditions. DMNQ does not form adducts with GSH or cysteine (Cys), yet it readily oxidizes H2S to polysulfides and sulfoxides. …

Newborn mammalian cardiomyocytes quickly transition from a fetal to an adult phenotype that utilizes mitochondrial oxidative phosphorylation but loses mitotic capacity. We tested whether forced reversal of adult cardiomyocytes back to a fetal glycolytic phenotype would restore proliferative capacity. We deleted Uqcrfs1 (mitochondrial Rieske iron-sulfur protein, RISP) in hearts of adult mice. As RISP protein decreased, heart mitochondrial function declined, and glucose utilization increased. Simultaneously, the hearts underwent hyperplastic remodeling during which cardiomyocyte number doubled without cellular hypertrophy. Cellular energy supply was preserved, AMPK activation was absent, and mTOR activation was evident. In ischemic hearts with RISP deletion, new cardiomyocytes …

Improving Quality Of Life In Menopausal Women Through A Best Practice Protocol: The Use Of Hormone Therapy, Mindfulness-Based Module And Exercise, Claire Czerwonka

The Not-So-Benign Sickle Cell Trait: A Case Of Renal Medullary Carcinoma, Fatima Halilu, Siddartha Guru, Fuscaldo Joseph

Journal of Community Hospital Internal Medicine Perspectives

Sickle cell trait (SCT) has long been considered a benign carrier state with malarial protection, but carriers can be affected by increased venous thromboembolism, exercise-related injury, renal complications and very rarely a fatal renal malignancy. Renal medullary carcinoma is a very rare and aggressive renal tumor described almost exclusively in sickle cell trait. A review of the current literature provides clues to this link and describes trends expected in these cases. We report a case of renal medullary carcinoma in a 32-year-old female with known sickle trait who presented with cough, hemoptysis, left flank pain and gross hematuria. Initial presentation …

Nsaids Role In Triggering Ibd Exacerbations; Reality Or Misunderstanding? A Systematic Review, Alec Swartz, Malitha Hettiarachchi

Conference Presentation Abstracts

Introduction: Initial studies seemed to show that NSAID use was associated with increased risk of IBD exacerbation. Supported by known role of COX-1/2 isoenzymes (specifically their prostaglandin [PG] products) in maintaining GI mucosal barrier and mediating inflammation Combination of early research findings and COX prostaglandin knowledge resulted in NSAID avoidance in IBD patients. Recent data seemingly contradicts prior research, and NSAID use is predicted to not play a role in IBD exacerbation Methods: We conducted a systematic review of the literature using PubMed and American Journal of Gastroenterology. Of the thousands of results, we narrowed our results to 4 recent …
