Acute Mastoiditis - Beginning of COVID-19 Infection - Case Report
Authors: Chialda Mihaela 
Published: April 2021

Abstract
Particular onset of Sars-Cov-2 infection, by acute mastoiditis without symptoms specific to the case definition. Mastoiditis is part of inflammatory diseases of the middle ear and is important because of its frequency and life-threatening complications due to the close relationship between the middle ear and the cranial cavity. An acute middle ear inflammation may follow a serious course even if the tympanic membrane does not perforate. In the pathogenesis of acute suppurations of the middle ear, the Eustachian tube plays a major role in the appearance of inflammation and the development of the disease. The most common germ can be - a virus whose initial effect is congestion of mucosa and reduce resistance to biological defence by promoting rapid superinfection with Hemophilus Pneumococcus, Staphylococcus, and others. Sars-Cov-2 infection begins with respiratory phenomena and clinical and biological inflammatory syndrome. This article presents a case of Sars-Cov-2 infection with atypical onset of acute mastoiditis. The clinical importance lies in the fact that the virus can migrate from the nose and nasopharynx through its Eustachian tube into the middle ear and from here to the mastoid. The presence of the virus in the middle ear is almost constant even if the patient is asymptomatic. This requires precautions in all surgical maneuvers at this level in patients with Sars-Cov-2 infection.

Authors: Helgiu Alina 
Published: April 2021

Abstract
Hand pain is a common complaint in the hemodialysis patient on arteriovenous fistula. The problem is related to its etiology: nervous or vascular, which requires different therapeutic solutions. Ischaemic etiology involves a deviation of the distal flow in the anastomosed vein, with the decrease of the distal flow and the installation of distal ischaemia. Nerve etiology involves compression of the median nerve in the carpal tunnel. The purpose of the paper is to present a case study of diagnosis and treatment of median nerve compression in hemodialysis patient.

Abstract
Peripheral arterial disease (PAD) is characterized by obstruction in the lower limbs, mainly due to atherosclerosis. The prevalence of the pathology in people under 40 years of age is 6% and 15-20% in the population over 65 years old.(1,2) Approximately 50% of the affected persons are, at the time of examination, asymptomatic.(3) The most important risk factors associated with this condition are smoking, diabetes mellitus (DM), high cholesterol and high blood pressure (HBP). The current study shows that, regardless of the association of risk factors or pre-hospital treatment, these patients do not benefit from a certain type of treatment (drug or interventional), which corresponds to the existing data in the literature, which do not document the choice of type of treatment depending on the patient’s age or comorbidities.

Published: April 2021

Abstract
Platelet indices have been linked to the severity and prognosis of coronary artery disease, but a very small number of studies assessed them under dual antiplatelet therapy after percutaneous coronary intervention (PCI). The aim of this study was to evaluate changes in mean platelet volume (MPV), platelet distribution width (PDW) and platelet-large cell ratio (P-LCR) in these patients. A number of 437 patients with stable coronary artery disease, 131 patients with non ST segment elevation acute coronary syndrome and 151 patients with ST segment elevation myocardial infarction were included in the study. There was no difference between the three groups regarding platelet indices prior to PCI. Follow-up data was available for 181 patients, at a mean follow-up time of 69 (46-98) days. MPV, PDW and PLC-R were similar to those prior to PCI in all three groups. Regarding the P2Y12 inhibitor, clopidogrel or ticagrelor, there was no difference at follow-up between platelet indices irrespective of the indication for PCI.

Published: April 2021

Abstract
The alarming spread of the novel Coronavirus necessitated the cessation of elective therapeutic procedures in most health-care facilities. This strategy has limited the spread of the virus, but with a huge socio-economic impact. For this reason, the resumption of elective surgery in the context of the coronavirus pandemic is a difficult, but necessary process. Addressing this delicate situation requires interdisciplinary collaboration, so as to ensure high quality medical care for all patients, with consideration to protection of the staff involved in the care of the surgical patient.

Abstract
Multiple biological parameters were proposed to evaluate the surgical stress response in the early postoperative period. Granulocyte/lymphocyte (G/L) ratio may be a useful marker and widely available. Measuring some of known surgical stress related markers together with G/L ratio we tried to confirm the superiority of laparoscopic approach and efficiency of the G/L ratio monitoring in this period. Materials and methods: 52 colorectal cancer patients who underwent elective surgery in a private clinical hospital were evaluated preoperatively and postoperatively (day 1 and day 5) for the: TNF-α, cortisol, C reactive protein (CRP) and G/L ratio. Results: Only CRP levels were significantly lower in the laparoscopy group in day 1 (74.07 vs 50.32, p=0.0461) and day 5 (18.37 vs 7.32, p=0.0001). The G/L ratio showed strong correlation with CRP levels in all measurements. Conclusions: Measurement of postoperative CRP levels confirmed the reduced surgical stress of laparoscopic colectomy for colorectal cancer in our clinic.

Authors: Gînfălean Georgeta 
Published: April 2021

Abstract
Considering actual SARS-COV 2 pandemic, the comfort and time of the female patient’ trend is to minimize the time spent in the doctor’s office, so that auto-testing is a solving problem in this context. This paper aims at the importance of self-collected urine and vaginal samples, since actual studies are showing that is a complementary method in HPV-testing and a screening method for prevention of cervical cancer. Genital HPV infection is responsible for approximately 99% of cervical cancers, and is considered a sexually transmitted disease. Given that eight out of ten patients have at least one episode of HPV infection in their lifetime, there is a need for a method of early detection of genital HPV infection. Cervical cancer is the second type of diagnosed cancer in the rank of genital cancers and the third leading cause of cancer death among the female population. In Romania, the frequency of cervical cancer and mortality caused by this type of cancer remains high. In 2018 Globocan, it was mentioned that the occurrence of cervical cancer in Romania was 8.6%, and the mortality was 19.5/10,000 women. Worldwide, the following have been implemented: primary prevention programmes (via immunization) and secondary prevention programmes – traditional cytological testing, to which co-tests have been added. In the co-testing sector, there has been found with an updated visa – the self-harvesting test, being considered a complementary and innovative method in genital HPV testing, which aims to: identify the presence of highly oncogenic HPV strains with a marked sensitivity. Self-harvesting testing aims to: signal the presence of highly oncogenic strains, extrapolation can lead to early identification of the number of cases of precancerous lesions of the cervix and implicitly of cervical cancer.

Abstract
The objectives of this study were to determine the length-weight relationships (LWRs), chelae length (ChL)-width (ChW) relationships, carapace length (CL)-width (CW) relationships, sexual dimorphism, and condition factor (K) of Cherax gherardiae from Maybrat, West Papua Indonesia. The sex ratio of C. gherardiae was found to be 1.04:1. The LWRs for males, females, and all individuals were W = 0.225L1.96, W = 0.181L2.02, and W = 0.187L2.03, respectively. Males and females exhibited negative allometric growth (b<3). There was no significant difference in lengths between males and females; however, the weight of males was greater than that of females. The K values for males, females, and all individuals were 3.17, 3.09, and 3.13, respectively. The ChL of the crayfish ranged from 1.0 to 7.5 cm, and the ChW ranged from 0.4 to 2.5 cm. The CL of crayfish ranged from 1.6 to 6.0 cm, and the CW ranged from 0.6 to 4.1 cm. Males had longer chelae and carapaces than did females. There was no significant difference in chelae width or carapace width between males and females. The ChL-ChW relationships for males, females, and all individuals were ChW = 0.312ChL + 0.260, ChW = 0.397ChL - 0.050, and ChW = 0.345ChL + 0.119, respectively. The CL-CW relationships for males, females, and all individuals were CW = 0.750CL-0.955, CW = 0.526CL - 0.178, and CW = 0.635CL-0.543, respectively.

Abstract
This study focused on testing Artemia sp. zooplankton saturation with freshwater microalgae biomass and then using this method to correct the nutritional composition of Artemia. Accordingly, the influence of three species of microalgal monocultures was analyzed (2 freshwater – Desmodesmus armatus (Chod.) Hegew. and Chlorella vulgaris Veijerinck; one halophilous – Dunaliella viridis Teodor.). The algal monocultures were applied once in a quantity of 2-3 × 106 cells × l−1 for each 200,000 Artemia individuals hatched. The control group Artemia did not receive algae. The enrichment process lasted 24 h, and control measurements were performed every 6 h. The survival of Artemia nauplii, their proteolytic activity, and the content of proteins, lipids, and carotenoids were analyzed. The choice of algae species for Artemia enrichment was guided by the size of the algal cells and their biochemical composition. Selected algae contained about 50% protein, 20% lipid, and 12 mg of carotenoids per g of dry weight. Using algae to saturate the Artemia nauplii permitted reducing their mortality during the 24 h enrichment regime. The introduction of C. vulgaris biomass halved this value. The use of algae also increased the proteolytic activity in Artemia nauplii and the content of proteins, lipids, and carotenoids in their biomass. The best results of the bioencapsulation of Artemia nauplii with algae was with the C. vulgaris biomass.

Authors: Jan Kousar , Ahmed Imtiaz 
Published: April 2021

Abstract

Schizothorax labiatus (McClelland) is considered to be one of the most economically important fish species among Schizothorax spp. A total of twenty-four morphometric and five meristic characters were examined; 18 of the morphometric characters as percentages of total length and four characters as percentages of head length were studied. It was found that the characters of standard length, fork length, pre pelvic length, pre anal length, and pre dorsal length had the highest correlations with total length, whereas dorsal fin height followed by caudal fin height had the lowest correlations. In percentages of head length post orbital length had the highest correlation whereas snout length had the lowest correlation. Overall, the results revealed that all the morphometric characters exhibited linear relationships and depicted significantly (P < 0.05) high degree of correlation, while the meristic characters counted were constant in all sizes of S. labiatus, indicating that they were independent of body size. The study provided basic information that will be useful for fish biologists and researchers in the future management and conservation of this fish species.

Abstract
Industrial wastewater can be properly treated using nanotechnologies and nanomaterials. This paper presents the synthesis and characterization of three series of magnetic nanoparticles (MNPs) and corresponding thin films, used for the degradation of organic compounds and removal of heavy metals from industrial wastewater. The samples were obtained by co-precipitation from a ferric (Fe3+) and ferrous (Fe2+) ions solution in a molar ratio of 2:1, at temperatures between 80-95 °C. The characterization of the samples was performed by scanning electron microscopy (SEM), and X-ray diffraction (XRD) methods. The magnetic nanoparticles were deposited on glass substrates by the centrifugal coating technique and the optical and magneto-optical activity was investigated by UV-Vis spectroscopy and magnetic circular dichroism technique (MCD). The effect of the investigated samples on the decomposition under UV irradiation of organic dyes was monitored by UV-Vis spectroscopy. Our preliminary results have shown that the magnetite and maghemite MNPs can be effective in UV degradation of methylene blue (MB) dye.

Between Mobility and Inclusion: The Position of Mother Tongue Instruction in Sweden and Denmark
Authors: Broerse Inga 
Published: April 2021

Abstract
Migration to Scandinavia has taken place quite similarly in Sweden and Denmark since the Second World War. However, from the 1980s onwards, Sweden and Denmark have become increasingly dissimilar in terms of migration policy, which went hand in hand with education policy for newcomers. Mother tongue instruction for newcomers may improve the process of integration and social cohesion; nevertheless, this is provided for differently in Sweden and Denmark. This study takes into account different social dynamics in order to research what the position of mother tongue instruction is in policy documents and media discourse in both Sweden and Denmark, to determine what the effects of mother tongue instruction are, and subsequently to figure out what is necessary to find the balance between mobility and inclusion – all these for creating further social cohesion and avoiding segregation.
The Boundaries of the Carpathian Basin – Frontiers and Regions
Authors: Bakk Miklós 
Published: April 2021

Abstract
The Carpathian Basin (or Pannonian Basin) is the south-eastern part of Central Europe, its geopolitical place being defined by geography (it is placed between the Eastern Alps, the Dinaric Alps, and the Carpathian Mountains) and from historical point of view by the fact that its core region was ruled for many centuries by the Hungarian Kingdom and the Habsburg Monarchy, and the neighbouring states aimed to extend their territories in the basin reducing the central role of the basin from the margins. The changes of the spatial domination in the Carpathian Basin created several centre–periphery relations, which established, through a longue durée, specific social features in some border regions of the Carpathian Basin. This paper examines from the viewpoint of limology (border studies) three frontier regions of the basin, Spiš, Székely Land, and Banat, and investigates the historical process of the regional construction in order to ascertain what circumstances helped or blocked these periphery constructions.

Published: April 2021

Abstract
Modification of cotton with 3-chloro-2-hydroxypropyltrimethylammonium chloride (CHPTAC) has been studied extensively and can be operated by means of exhaustion, cold pad-batch, and continuous and pad-steam methods. Most of the research addresses the cationization of cotton fabric after bleaching or mercerization, or during the mercerization process. In our studies, we performed a comparison of the cationization effects on raw, enzymatic, and alkali-scoured cotton knitted fabrics applying CHPTAC according to the exhaustion method. The charge density of the cotton surface was measured using a Muetek Particle Charge Detector and a “back titration” method with polyelectrolytes. These results were compared with the nitrogen content in the samples, K/S measurements of tested samples after dyeing with anionic dye (Acid Yellow 194), and other physicochemical parameters such as weight loss, whiteness, and wettability.

Abstract
Let f and g be two nonconstant meromorphic functions sharing two finite sets, namely S ⊂ ℂ and {∞}. We prove two uniqueness theorems under weaker conditions on ramification indices, reducing the cardinality of the shared set S and weakening the nature of sharing of the set {∞} which improve results of Fang-Lahiri [7], Lahiri [17], Banerjee -Majumder-Mukherjee [5] and others.

Abstract
One of the fundamental elements of a scientist's work is the ability to lead observations of the phenomena that surround us and based on them making conclusions. These observations are conducted within the so-called scientific experiments. Lessons learned based on the results obtained in experiments allow researchers to better understand the essence of the phenomena occurring in the world around us. Drawing conclusions is not always easy. In order to achieve this skill, we must possess a well-established knowledge in the field of the phenomenon that interests us. The most striking example of how important skills are observation and drawing proper conclusions is the phenomenon of global climate warming. The main parameter influencing temperatures registered on Earth is the concentration of greenhouse gases in the atmosphere, and especially carbon dioxide created from combustion processes. A significant role in studies of the reduction of CO2 emissions plays chemists. To be sure that conducted by them experiments are optimally designed, it is necessary to ensure them with proper education already at the secondary school level. The main aim of this article was to conduct the study in order to explain chemical issues that create the greatest cognitive difficulties among students. The second aim of the article was to propose a chemical experiment to students that would allow them to find out more about the phenomena governing in the area of problematic issues. The proposed experiment is based on the concept of solubility equilibrium. Results of preliminary tests that have been carried out after applying this experiment on a small group of students, indicated their better understanding of the studied subject.
