Flow cytometric analysis of platelet surface glycoproteins in the diagnosis of thirty-two Turkish patients with Glanzmann Thrombasthenia: a multicenter experience.

Turk J Med Sci 2021 May 7. Epub 2021 May 7.

Background/aim: Glanzmann thrombasthenia (GT) is a rare autosomal recessively inherited bleeding disorder characterized by the quantitative (type 1 and type 2) or qualitative (type 3) deficiency in platelet membrane glycoprotein (GP) IIb/IIIa (CD41a/CD61) fibrinogen receptors. In type 1, 2 and 3, CD41a/CD61 expression is 5%, 5-20% and above 20%, respectively. In this study, diagnosis of GT was confirmed and subgroups were identified in 32 Turkish patients by flow cytometry analysis. Read More

Vulvar Varicosities in an Adolescent Girl with Morbid Obesity: A Case Report.

Children (Basel) 2021 Mar 7;8(3). Epub 2021 Mar 7.

Center for Adolescent Medicine and UNESCO Chair on Adolescent Health Care, First Department of Pediatrics, School of Medicine, National and Kapodistrian University of Athens, Aghia Sophia Children's Hospital, 11527 Athens, Greece.

Vulvar varicosities in nonpregnant females, either isolated or as a part of the pelvic congestion syndrome, are rare. We present a case of an adolescent girl with morbid obesity with bilateral bluish protrusions on the labia minora, as an incidental finding, that coincided with her excessive weight gain. The adolescent underwent thorough clinical examination, doppler ultrasound, contrast venography and varicography, and magnetic resonance angiography to rule out alternative diagnoses. Read More

Faculty of Chemistry, Gdansk University of Technology, 11/12 Narutowicza St., Gdansk, 80-233, Poland.

Lake ecosystems are strongly coupled to features of their surrounding landscapes such as geomorphology, lithology, vegetation and hydrological characteristics. In the 2010-2018 summer seasons, we investigated an Arctic flow-through lake system Revvatnet, located in the vicinity of the coastal zone of Hornsund fjord in Svalbard, characterising its hydrological properties and the chemical composition of its waters. The lake system comprises of a small upper lake and a large lower one, the latter cone-shaped, with -29. Read More

On the Efficacy of Water Transport in Leaves. A Coupled Xylem-Phloem Model of Water and Solute Transport.

Front Plant Sci 2021 4;12:615457. Epub 2021 Feb 4.

Phenomics and Bioinformatics Research Centre, University of South Australia, Mawson Lakes, SA, Australia.

In this paper, we present and use a coupled xylem/phloem mathematical model of passive water and solute transport through a reticulated vascular system of an angiosperm leaf. We evaluate the effect of leaf width-to-length proportion and orientation of second-order veins on the indexes of water transport into the leaves and sucrose transport from the leaves. We found that the most important factor affecting the steady-state pattern of hydraulic pressure distribution in the xylem and solute concentration in the phloem was leaf shape: narrower/longer leaves are less efficient in convecting xylem water and phloem solutes than wider/shorter leaves under all conditions studied.

Dural Venous Channels: Hidden in Plain Sight-Reassessment of an Under-Recognized Entity.

AJNR Am J Neuroradiol 2020 08 16;41(8):1434-1440. Epub 2020 Jul 16.

From the Departments of Radiology (M.S., E.R., P.K.N.).

Background And Purpose: Tentorial sinus venous channels within the tentorium cerebelli connecting various cerebellar and supratentorial veins, as well as the basal vein, to adjacent venous sinuses are a well-recognized entity. Also well-known are "dural lakes" at the vertex. However, the presence of similar channels in the supratentorial dura, serving as recipients of the Labbe, superficial temporal, and lateral and medial parieto-occipital veins, among others, appears to be underappreciated.

Bioimaging Techniques Reveal Foliar Phosphate Uptake Pathways and Leaf Phosphorus Status.

Plant Physiol 2020 08 15;183(4):1472-1483. Epub 2020 Jun 15.

Department of Plant and Environmental Sciences, University of Copenhagen, 1871 Frederiksberg C, Denmark

Global demand for phosphorus (P) requires new agronomic practices to address sustainability challenges while increasing food production. Foliar P fertilization could increase P use efficiency; however, leaf entry pathways for inorganic phosphate ion (Pi) uptake remain unknown, and it is unclear whether foliar P applications can meet plant nutrient demands. We developed two techniques to trace foliar P uptake in P-deficient spring barley () and to monitor the effectiveness of the treatment on restoring P functionality. Read More

Vesicules or placental lakes in ultrasonography, determining the correct etiology.

J Gynecol Obstet Hum Reprod 2021 Jun 29;50(6):101738. Epub 2020 Apr 29.

Department of Obstetrics and Gynecology, Hospices Civils de Lyon, Hôpital Femme Mère Enfant, Université Claude Bernard, Lyon 1, Bron, Lyon 69500, France.

The prenatal examination of the placenta is often an afterthought to that of the fetus in ultrasonography. Not giving the placenta its due may however result in potentially serious placental pathologies remaining undiscovered, notably in the presence of anechoic zones. These latter have earned numerous names, including "placental lakes", "placental venous lakes", "placental lacunae" or "placental caverns" among others, but they have received little attention in the literature.

Cerebral lipiodol embolism related to a vascular lake during chemoembolization in hepatocellular carcinoma: A case report and review of the literature.

World J Gastroenterol 2018 Oct;24(37):4291-4296

Department of Radiological Sciences, Nagasaki University Graduate School of Biomedical Sciences, Nagasaki 852-8501, Japan.

A male patient underwent conventional transcatheter chemoembolization for advanced recurrent hepatocellular carcinoma (HCC).

APMIS 2018 May 6;126(5):403-412. Epub 2018 Apr 6.

Institute of Biomedical Sciences, National Sun Yat-Sen University, Kaohsiung, Taiwan.

The aim of this study was to investigate the associations among the immunoexpression levels of manganese superoxide dismutase (Mn-SOD), glutathione peroxidase (GPx), and myeloperoxidase (MPO) in lip squamous cell carcinoma (LSCC) tissues and the clinicopathological characteristics, and prognostic factors in patients with LSCC. The immunoexpression levels of Mn-SOD, GPx, and MPO were examined in 76 LSCC tissue samples using immunohistochemical staining on tissue microarray slides, and compared to those in normal lip mucosa adjacent to venous lakes (normal controls), normal tissue adjacent to corresponding tumors (NTACT), and recurrent tumors. Associations between immunoexpression levels and clinicopathological characteristics were analyzed using the Student's t-test. Read More
