Acute hemolytic transfusion reaction caused by anti-Yt.

Immunohematology 2021 Mar;37(1):13-17

Department of Transfusion Medicine and Transplantation Biology, University Clinical Hospital Zagreb , Zagreb , Croatia .

Many patients with anti-Yt receive multiple transfusions of Yt(a+) red blood cells (RBCs) with no ill effects. However, anti-Yt has been implicated in hemolytic transfusion reactions. Antibody identification typically determines specificity of antibodies and their clinical significance to justify blood requirements for antigen-negative blood when clinically significant antibodies are involved.

Microvesicles and Exosomes Released by Amnion Epithelial Cells Under Oxidative Stress Cause Inflammatory Changes in Uterine Cells.

Biol Reprod 2021 May 7. Epub 2021 May 7.

Division of Maternal-Fetal Medicine and Perinatal Research, Department of Obstetrics and Gynecology, The University of Texas Medical Branch at Galveston, Galveston, TX 77555, USA.

Extracellular vesicles (EVs) play a crucial role in feto-maternal communication and provide an important paracrine signaling mechanism in pregnancy. We hypothesize that fetal cells-derived exosomes and microvesicles (MVs) under oxidative stress carry unique cargo and traffic through feto-maternal interface, which cause inflammation in uterine cells associated with parturition. Exosomes and MVs, from primary amnion epithelial cell (AEC) culture media under normal or oxidative stress (OS)-induced conditions, were isolated by optimized differential centrifugation method followed by characterization for size (nanoparticle tracking analyzer), shape (transmission electron microscopy), and protein markers (western blot and immunofluorescence).

Biol Reprod 2021 May 7. Epub 2021 May 7.

Department of Animal Science, South Dakota State University, Brookings SD; USA.

Embryo survival and pregnancy success is increased among animals that exhibit estrus prior to fixed time artificial insemination (AI), but there are no differences in conceptus survival to d16. The objective of this study was to determine effects of preovulatory estradiol on uterine transcriptomes, select trophectoderm transcripts, and uterine luminal fluid (ULF) proteins. Beef cows/heifers were synchronized, artificially inseminated (d0), and grouped into either high (highE2) or low (lowE2) preovulatory estradiol. Read More

Low plasma angiotensin-converting enzyme 2 level in diabetics increases the risk of severe COVID-19 infection.

Aging (Albany NY) 2021 May 6;13. Epub 2021 May 6.

Department of Cardiology, The Affiliated Sir Run Run Hospital of Nanjing Medical University, Nanjing, China.

Patients with pre-existing chronic diseases are more susceptible to coronavirus disease 2019 (COVID-19), yet the underlying causes of increased risk are of infection remain unclear. Angiotensin-converting- enzyme 2 (ACE2), the cell surface receptor that recognizes the coronavirus spike protein has protective effects against inflammation and chronic hyperglycemia in animal models. The roles of ACE2 in severe SARS-CoV-2 infections remains ambiguous due to contradictory findings. Read More

The predictive value of intraoperative visual evoked potential for visual outcome after extended endoscopic endonasal surgery for adult craniopharyngioma.

J Neurosurg 2021 May 7:1-11. Epub 2021 May 7.

1Department of Neurosurgery, Beijing Tiantan Hospital, and.

Objective: Due to the proximity of craniopharyngioma to the optic apparatus, one of the most common complications after surgery is visual deterioration. Intraoperative visual evoked potential (VEP), as a means of real-time visual function monitoring, has been integrated into transsphenoidal surgery for pituitary adenoma to predict postoperative visual outcome. Compared with pituitary tumor, craniopharyngioma often adheres to optic nerves, with increased risk of postoperative visual impairment. Read More

Department of Industrial Engineering, University of Trento, Via Sommarive 9, 38123 Trento, Italy.

The neuroscience field has increased enormously over the last decades, achieving the possible real application of neuronal cultures not only for reproducing neural architectures resembling in vivo tissues, but also for the development of functional devices. In this context, surface patterning for cell confinement is crucial, and new active materials together with new protocols for preparing substrates suitable for confining cells, guiding their processes in the desired configuration are extremely appreciated. Here, TiO sol-gel derived films were selected as proof-of-concept materials to grow neurons in suitable confined configurations, taking advantage of the biocompatible properties of modified TiO substrates.

Pulse wave velocity is decreased in acromegaly compared to non-acromegaly study participants with similar cardiovascular risk profile.

Growth Horm IGF Res 2021 Apr 29;57-58:101395. Epub 2021 Apr 29.

Almazov National Medical Research Centre, Ulica Akkuratova 2, St. Petersburg 197341, Russia.

Objective: Acromegaly patients were reported to have an increased arterial stiffness that could contribute to the frequent cardiovascular complications in this population. The chronic excess of GH and IGF-1 may lead to arterial stiffening via different mechanisms, including hypertension, impaired glucose tolerance and dyslipidemia, however, it is not known whether the activation of GH/IGF-1 axis might influence arterial stiffening independently of cardiovascular risk factors. The objective of this prospective case-control study was to compare arterial stiffness assessed with pulse-wave velocity (PWV) in acromegaly versus non-acromegaly group with similar cardiovascular risk profile.
