COVID-19, neurovascular thrombotic problem and short summary on blood coagulation disorder: a brief review

COVID-19 is the present global public health problem. This respiratory viral infection can manifest atypical presentation including neurological presentations. An important neurological problem in COVID-19 is neurovascular thrombosis. The basic pathogenesis of thrombosis in neurological system is explainable by the basic principle of thrombohemostasis. A hypercoagulability is a possible problem seen in some COVID-19 cases. In this brief review, the authors summarize venous and arterial thrombosis of neurovascular system as a complication of COVID-19. The updated pathophysiology of COVID-associated blood coagulation disorder is discussed. In addition, consideration regarding new COVID-19 vaccine related thrombotic adverse event is also raised.

Shaymaa Neamah Mohammed ALMKHELIF

Orhan Pamuk is considered one of the most important novelists and short story writers in Turkish Literature. The full name is Ferit Orhan Pamuk. He was born in Istanbul in 1952. He is now 69 year old and still alive. He is considered the first Turkish writer who wins Noble Prize for literature for the year 2006. He won several other prizes, one of which is Noble Prize because he has several short stories and novels. The White Castle is one of the most important novels for the author Orhan Pamuk who won the Noble Prize. It is considered a historical novel that belongs to the Ottoman Empire era in the 17th century. The novel revolves on one of the passengers who travels to Napoli through the sea. The Ottoman pirates captivate him and sell him to one of the Turkish people as slave. Both the master and the slave almost share the same features although they are from different geographic areas. The novel deals with the similarities and differences among the people of the and the people of the west in an accurate way. The concept of dream is to wish something favorable in the future. There were several types and ways of daydreams. This concept is different from one person to another. This term cannot be clearly defined because of its subjective nature. It appears in a very wide area, from the ability to maintain the thing dreamt to achieve to the world of dreams of the dreamer. Hence, the reality of daydreams is a wonderful art that is different from one person to another. We start the research by giving inclusive summary. In the Introduction, there is short summary for the life and literary personality of the Turkish author Orhan Pamuk as well as his works. The research introduces information about the novel which is the subject of the research paper. It introduces, through detailed study for the novel The White Castle, a detailed explanation about the art of dreams.

Promoting Students' Soft Skills in a Telecommunication Engineering Course with an Elevator Pitch Activity

An elevator pitch is a short summary used to quickly and simply define a process, product, service, organization, or event and its value proposition. The name comes from the idea that it should be possible to deliver the sum-mary within the time span of an elevator ride, so anywhere between 30 sec-onds and 2 minutes, which means the key points need to get across quickly. In this particular educational context, technical students have been encour-aged to defend, under the typical rules of the elevator pitch, the knowledge acquired during the semester in a specific subject. This contribution focuses on the classroom experience and how the transversality of the activity can help students to strive and think in a different way than they are used to in the classroom of a technical career.

Quenching and Distortion*

This paper is based on a keynote lecture presented by Prof. Fechte-Heinen during the 2nd International Conference on Quenching and Distortion Engineering in April 2021. Firstly, it presents a short summary of the basics of distortion formation. The mechanisms and the potential for distortion with its carriers are discussed in more detail. Furthermore, the method of Distortion Engineering is explained. Finally, selected examples are presented that illustrate the connections between distortion and the quenching process.

Phospholipases and Reactive Oxygen Species Derived Lipid Biomarkers in Healthy and Diseased Humans and Animals – A Focus on Lysophosphatidylcholine

Phospholipids (PL) are converted into lipid biomarkers by the action of phospholipases and reactive oxygen species (ROS), which are activated or released under certain physiological and pathophysiological conditions. Therefore, the in vivo concentration of such lipid biomarkers [e.g., lysophospholipids (LPLs)] is altered in humans and animals under different conditions such as inflammation, stress, medication, and nutrition. LPLs are particularly interesting because they are known to possess pro- and anti-inflammatory properties and may be generated by two different pathways: either by the influence of phospholipase A2 or by different reactive oxygen species that are generated in significant amounts under inflammatory conditions. Both lead to the cleavage of unsaturated acyl residues. This review provides a short summary of the mechanisms by which lipid biomarkers are generated under in vitro and in vivo conditions. The focus will be on lysophosphatidylcholine (LPC) because usually, this is the LPL species which occurs in the highest concentration and is, thus, easily detectable by chromatographic and spectroscopic methods. Finally, the effects of lipid biomarkers as signaling molecules and their roles in different human and animal pathologies such as infertility, cancer, atherosclerosis, and aging will be shortly discussed.

Some preliminary notes on the limited 2020 campaign of the Palamas Archaeological Project (PAP)

This paper presents a short summary of archaeological operations carried out in 2020 in the area of the modern village of Vlochos on the western Thessalian plain, Greece, as part of the Palamas Archaeological Project (PAP). Initially, the project aimed to conduct a significant campaign of fieldwork during the 2020 season, but operations were severely scaled back by limitations imposed by the COVID-19 pandemic. Therefore, only a small-scale campaign, aimed at method testing and exploratory investigation, could be carried out. Fieldwork included an evaluation of complimentary geophysical techniques, cleaning operations, and oral history enquiries. The work—despite its limitations—highlighted the value of using multiple geophysical techniques, as well as proving the importance of a systematic cleaning of the site. Overall, the first season of PAP highlighted the productivity of the research project and will act as a strong foundation for the forthcoming field seasons.

An unusual triphasic transmitral flow: A special case of “mid-diastolic mitral regurgitation” due to acute aortic regurgitation

Short summary A 51-year-old man presented with decompensated heart failure due to acute aortic regurgitation; he also showed “mid-diastolic mitral regurgitation”, presumably originating from pressure crossover between the left ventricle and atrium.

The first molecular phylogeny of the weevil subfamily Lixinae (Coleoptera: Curculionidae) casts doubts on the monophyly of its tribes

This paper targets the nearly cosmopolitan weevil subfamily Lixinae. A phylogenetic analysis of one mitochondrial and two nuclear DNA fragments obtained from 87 Lixinae and 49 outgroup terminals strongly supports the monophyly of the subfamily. The molytine tribe Mecysolobini is the likeliest sister group of Lixinae; adults of both taxa share the likely synapomorphic condition of the greatly shortened labial palpi. Phylogenetic relationships within the subfamily are poorly resolved. None of three Lixinae tribes is recovered as monophyletic. The subfamily’s oldest dichotomy is formed by a clade of two genera Rhabdorrhynchus plus Pachycerus sister to the rest of the subfamily. The genera Chromonotus, Larinus, Lixus, and Stephanocleonus are recovered as non-monophyletic. The genera Asproparthenis, Chromonotus, and Maximus form a strongly supported clade. The genus Eumecops is the likeliest sister to the clade formed by the genera Stephanocleonus plus Coniocleonus. The cleonine genus Scaphomorphus is a sister to a subset of externally most similar species of the genus Lixus; the same clade likely includes the genus Lixoglyptus not represented in the analysis. As an aside we provide a short summary of active flight in adult Cleonini.
