REVIEW
M Merad, A Alibay, S Ammari, S Antoun, A Bouguerba, S Ayed, F Vincent
Pulmonary tumor thrombotic microangiopathy syndrome is a rare clinicopathological entity in which tumor cell micro-emboli in the pulmonary microcirculation induced thrombotic microangiopathy. This can cause respiratory failure, and acute or sub-acute right heart failure. Histological features include micro tumor emboli in the small arteries and arterioles of the lung associated with thrombus formation and fibro-cellular and fibro-muscular intimal proliferation. The diagnosis is however extremely difficult to make before death...

Type 2 diabetes (T2DM) is associated with increased risk of fractures. Soy supplementation has been shown to have a beneficial effect on bone turnover markers (BTM) in postmenopausal women. However, the effect of soy supplementation on BTM in T2DM and particularly in men is unclear. We performed an analysis of a randomized double blind parallel study of 200 men with T2DM treated with soy, either with or without isoflavones. Outcome measures were type I collagen crosslinked beta C-telopeptide (βCTX), and type 1 procollagen-N-propeptide (P1NP)...

Phyllodes tumours (PTs) of the breast are uncommon fibroepithelial neoplasms comprising 0.3-1.0% of all primary breast tumours. The majority of PTs are benign and generally well managed with surgery. However, malignant PTs, and occasionally borderline PTs, can behave in a clinically aggressive manner by metastasizing to distant organs. Although distant metastasis is rare, the prognosis of patients with metastasis is dismal as many are unresponsive to standard chemotherapy and the risk of death is high. In this study, we correlated clinicopathological parameters to survival outcomes in a cohort of patients diagnosed with malignant PTs in our institution...

Ayed O Ayed, Sameer A Parikh
The past two decades have witnessed a paradigm shift in the management of patients with chronic lymphocytic leukemia (CLL), particularly with the introduction of targeted therapies to clinical practice. Ibrutinib is an irreversible inhibitor of Bruton's tyrosine kinase (BTK) and has shown significant efficacy and tolerability, even in heavily treated patients. Despite improvement in outcomes, patients do ultimately relapse. Those who develop disease progression on ibrutinib are a particularly high-risk population with poor outcomes...

Hyperproliferative endothelial cells (ECs) play an important role in the pathogenesis of PAH. Anoctamin-1 (Ano1), a calcium activated chloride channel, can regulate cell proliferation and cell cycle in multiple cell types. However, the expression and function of Ano1 in the pulmonary endothelium is unknown. We examined whether Ano1 was expressed in pulmonary ECs and if altering Ano1 activity would affect EC survival. Expression and localization of Ano1 in rat lung microvascular ECs (RLMVECs) was assessed using immunoblot, immunofluorescence, and subcellular fractionation...

The ligand-binding βI and αI domains of integrin are the best-studied von Willebrand factor A (VWA) domains undergoing significant conformational changes for affinity regulation. In both βI and αI domains, the α1- and α7-helixes work in concert to shift the metal-ion-dependent-adhesion-site between the resting and active states. An absolutely conserved Gly in the middle of the α1-helix of βI helps maintain the resting βI conformation, while the homologous position in the αI α1-helix contains a conserved Phe...

The bacterial cell division regulators MinD and MinE together with the division inhibitor MinC localize to the membrane in concentrated zones undergoing coordinated pole-to-pole oscillation to help ensure that the cytokinetic division septum forms only at the mid-cell position. This dynamic localization is driven by MinD-catalyzed ATP hydrolysis, stimulated by interactions with the MinE anti-MinCD domain. This domain is buried in the 6-β-stranded MinE closed structure, but is liberated for interactions with MinD, giving rise to a 4-β-stranded open structure through an unknown mechanism...
