Template-Independent Poly(A)-Tail Decay and RNASEL as Potential Cellular Biomarkers for Prostate Cancer Development.

Cancers (Basel) 2022 Apr 29;14(9). Epub 2022 Apr 29.

Department of Chemistry, Faculty of Medicine, University of Niš, 18000 Niš, Serbia.

The post-transcriptional messenger RNA (mRNA) decay and turnover rate of the template-independent poly(A) tail, localized at the 3'-untranslated region (3'UTR) of mRNA, have been documented among subtle mechanisms of uncontrolled cancer tissue growth. The activity of Poly(A) deadenylase and the expression pattern of RNASEL have been examined. A total of 138 prostate tissue specimens from 46 PC patients (cancer specimens, corresponding adjacent surgically healthy tissues, and in their normal counterparts, at least 2 cm from carcinoma) were used.

Pulmonary tumor thrombotic microangiopathy with thrombus in pulmonary artery caused by diffuse sclerosing variant of thyroid papillary adenocarcinoma: A case report.

Pulm Circ 2022 Jan 12;12(1):e12027. Epub 2022 Jan 12.

Department of Cardiology Nagoya University Graduate School of Medicine Nagoya Japan.

Pulmonary tumor thrombotic microangiopathy (PTTM) is a fatal disease associated with malignant tumors that progresses to pulmonary hypertension. Gastric cancer is the most common cause, followed by breast cancer and lung cancer, whereas PTTM due to thyroid cancer has not been reported. In addition to pulmonary obstruction by tumor embolism, tumor cells stimulate endothelial cells to release angiogenetic factors, which induce remodeling of pulmonary arteries and veins and lead to lymphatic obstruction.

The potential role of complement alternative pathway activation in hypertensive renal damage.

Exp Biol Med (Maywood) 2022 Apr 27:15353702221091986. Epub 2022 Apr 27.

Division of Nephrology, Ruijin Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai 200025, China.

Hypertensive renal damage is a common secondary kidney disease caused by poor control of blood pressure. Recent evidence has revealed abnormal activation of the complement alternative pathway (AP) in hypertensive patients and animal models and that this phenomenon is related to hypertensive renal damage. Conditions in the setting of hypertension, including high renin concentration, reduced binding of factor H to the glomerular basement membrane, and abnormal local synthesis of complement proteins, potentially promote the AP activation in the kidney.

Impact of Cerebral Autoregulation Monitoring in Cerebrovascular Disease: A Systematic Review.

Neurocrit Care 2022 06 5;36(3):1053-1070. Epub 2022 Apr 5.

Division of Stroke and Neurocritical Care, Stanford University, Palo Alto, CA, USA.

Cerebral autoregulation (CA) prevents brain injury by maintaining a relatively constant cerebral blood flow despite fluctuations in cerebral perfusion pressure. This process is disrupted consequent to various neurologic pathologic processes, which may result in worsening neurologic outcomes. Herein, we aim to highlight evidence describing CA changes and the impact of CA monitoring in patients with cerebrovascular disease, including ischemic stroke, intracerebral hemorrhage (ICH), and aneurysmal subarachnoid hemorrhage (aSAH).
