Dril Procedure: Treatment for Vascular Access Induced Hand Ischemia. Case Report
Authors: Helgiu Claudiu 
Published: April 2021

Abstract
Native vascular access (AVF arteriovenous fistula) for chronic hemodialysis (CH) performed proximally to the diabetic patient, between the brachial artery and the basilic vein or cephalic vein, determines the risk of distal (hand) ischemia. The correction of the ischemia can be done differently depending on its severity, starting from the vasodilator medication, reaching the cancellation of the vascular access with the accomplishment of the chronic hemodialysis on the central venous catheter. DRIL procedure (Distal Revascularization and Interval Ligation) corrects distal ischemia while maintaining functional vascular access, an important aspect in diabetic patients in whom vascular capital is deficient. We further describe a case of a diabetic patient with right L-T brachiocephalic arteriovenous fistula, with important ischemic phenomena in which the DRIL procedure resolved the ischemia, the patient using vascular access as usual, the second postoperative day.

Published: April 2021

Abstract
Neovascular Glaucoma (NVG) is a severe form of glaucoma characterized by neovascularization and the proliferation of fibrovascular tissue in the anterior chamber angle. Patients with NVG generally present with elevated intraocular pressure (IOP) and may experience severe pain. Ocular surface is affected by high IOP and can lead from moderated to marked conjunctival congestion that is frequently associated with edematous cornea. The aim of the study is to show how the high IOP can affect the ocular surface of the NVG patients and how we can treat and prevent the suffering. Materials and methods: We took in the study a number of 38 eyes from 35 patients with NVG in stage 3 with angle closure glaucoma, that presented high IOP and impaired ocular surface. Results and discussions: The ocular surface was damaged in patients that presented IOP between a minimum of 38 mmHg and maximum of 89 mmHg. The symptoms that patients presented were: conjunctival congestion in particular perikeratic, epithelial and stromal corneal edema, epithelial bubble, corneal ulcerations. Treatment followed rapid drop in IOP and the restoration and protection of ocular surface. The management of neovascular eye with high IOP was medical, laser and surgical. The restoration of ocular surface was made with lubricating hyperosmotic ophthalmic solutions, regenerative and protective agents. In all cases after the treatment was performed the ocular surface was restored. Conclusions: NVG is a very difficult pathology and is very hard to manage. The uncontrolled IOP in NVG patients affect the ocular surface and leads to complications. Long-term maintenance of normal intraocular pressure is important in NVG management but also in protecting the ocular surface.

Abstract
anastomotic leakage is one of the most important postoperative complications for colorectal cancer patients undergoing curative surgery. Early recognition of patients in risk would be essential for preventing the high mortality rates associated with these complications. C reactive protein (PCR), tumour necrosis factor (TNF-alpha), cortisol levels and granulocyte/lymphocyte ratio (G/L) were compared in this period in patients who developed leakage vs patients without this complication. Material and methods: 52 colorectal cancer patients who underwent elective surgery in a private clinical hospital were evaluated preoperatively and postoperatively for the patients. Results: 14 patients (26,9%) developed clinically significant anastomotic leakage. The best cut-off value for preoperative G/L ratio of 5,8 had sensitivity of 71,43% and specificity of 73,68%. Conclusions: Preoperative G/L ratio can be used as a largely available tool for identifying the colorectal cancer patients at high risk for anastomotic leakage.

Abstract
Chronic kidney disease is an important comorbidity of HIV infection causing real problems in the evolution and medical healthcare of HIV-positive patients. In recent years, a significant number of HIV-positive patients develop renal dysfunction, several mechanisms being incriminated: direct effect of the virus, toxic effect secondary to of antiretroviral medication, secondary to associated comorbidities, given that life expectancy has increased significantly in the last decade, thanks to the use of antiretroviral therapies. There are few studies in the literature to evaluate malformative renourinary pathology in patients with HIV infection. We present the case of a patient with HIV infection, horseshoe kidney, chronic kidney disease and incomplete Fanconi syndrome, secondary to the administration of tenofovir fumarate, a nucleoside reverse transcriptase inhibitor. Malformations, abnormalities or dysmorphysms of the renal tract should be considered in the HIV-positive patient with secondary renal dysfunction because they take a wide range of forms, are underdiagnosed and predispose to multiple complications, with varying degrees of severity, such as urinary tract infections, renal stones or progression of chronic kidney disease. Tenofovir fumarate and atazanavir must be avoided in patients with HIV infection and chronic renal dysfunction.

Published: April 2021

Abstract
Gastric cancer is one of the most common malignancies, associated with a high mortality and morbidity rate, especially in the elderly, the fourth leading cause of cancer mortality in Europe. Although the rate of diagnosis has declined in recent years, the prognosis of the disease and the mortality rate is still quite high. Laparoscopic surgery, accompanied by lymphadenectomy, is a curative method of treatment, used more and more frequently, especially in Eastern countries, both in the incipient disease and in advanced stages of the disease, which has many advantages over classical surgery.
We report the case of an 86-year-old man, who presented for marked physical asthenia, weight loss and severe anemia, in whom we performed laparoscopic distal radical gastrectomy with D2 lymphadenectomy and Roux-en-Y reconstruction. Histopathological examination established the diagnosis of low-grade / well-differentiated tubular adenocarcinoma G1 (WHO) / intestinal carcinoma (Lauren), with invasion in the lamina propria, developed on an intestinal-type adenoma. 21 lymph nodes were taken without tumor invasion.
This case highlights the complexity of laparoscopic intervention, with the proven advantages for the patient, like reduced surgical trauma and pain, with the decrease of postoperative complications, but also the difficulty of the surgical technique which requires advanced laparoscopic skills. Thus, in addition to its proven efficacy in cases of early gastric cancer, the technique can be extended to advanced malignancies, without affecting the oncological safety limit.

Published: April 2021

Abstract
Chemical analysis of different materials at the place where analytes are present (on-site analysis) has several advantages in comparison to analysis of these materials after delivering the samples to laboratory. Mobile devices, possessing expected properties in terms of using energy, mass and volume are needed for such analyses. The obtained results should be comparable to those obtained with the stationary instruments. Mass and ion mobility spectrometers are examples of the instruments fulfilling these requirements. At the beginning, the article describes the developments in combining of mass and ion mobility spectrometers (MS, IMS) with miniature gas chromatographs (GC). Both systems are used for analyses in the field, mainly for determination of environmental pollutions. They are used not only for analysis of typical chemicals present in different environmental compartments (in air, water and soil samples) but also for analysis of explosives, drugs and chemical warfare agents when fast results are needed. Particularly noteworthy is their applications in space exploration on the International Space Station. The selected examples of applications of miniaturised GC-MS and GC-IMS devices are presented in the second part of this mini review.

Abstract
Achieving energy conservation and emission reduction in the industry is an inevitable way to promote harmony between society and nature and achieve sustainable human development. China’s infrastructure construction industry is developing rapidly. Still, there is a lack of a well-established industry standard for evaluating the potential and level of energy reduction in infrastructure construction. A severe lack of quantitative research on energy-saving and CO2 outflow decreases the benefits of green development advances. This study takes the energy conservation and outflow decrease of construction waste slurry treatment in Guangdong Province, China, as the background, establishes an evaluation system with three rule levels: social, economic, and environmental, and adopts rough set theory to determine the weights of each index to ensure the objectivity of each index. According to the recommendations of the carbon emission calculation guidelines, select the relevant data to evaluate the energy-saving and emission reduction benefits of the new green construction technology of grouted piles in a road project in Guangdong Province. The results show that the development level and potential of energy saving and emission reduction technology in the construction sector in Guangdong Province are increasing year by year. It’s potential changes with the increase or decrease of highway mileage, and it is an urgent need to increase investment in pollution control. The research results can evaluate the benefits of energy-saving and carbon dioxide emission reduction in the construction industry, also be used as a reference to assess energy-saving and emission reduction in the construction industry in other countries.
Quantifying Urban Vegetation Coverage Change with a Linear Spectral Mixing Model: A Case Study in Xi’an, China
Authors: Zhao Xuan , Liu Jianjun 
Published: April 2021

Abstract
With the rapid development of urban area of Xi’an in recent years, the contradiction between ecological environmental protection and urban development has become prominent. The traditional remote sensing classification method has been unable to meet the accuracy requirements of urban vegetation monitoring. Therefore, how to quickly and accurately conduct dynamic monitoring of urban vegetation based on the spectral component characteristics of vegetation is urgent. This study used the data of Landsat 5 TM and Landsat 8 OLI in 2011, 2014 and 2017 as main information source and LSMM, region of variation grid analysis and other methods to analyse the law of spatial-temporal change of vegetation components in Xi’an urban area and its influencing factors. The result shows that: (1) The average vegetation coverage of the study area from 2011 to 2017 reached more than 50 %, meeting the standard of National Garden City (great than 40 %). The overall vegetation coverage grade was high, but it had a decreasing trend during this period. (2) The vegetation in urban area of Xi’an experienced a significant change. From 2011 to 2017, only 30 % of the low-covered vegetation, 24.39 % of the medium-covered vegetation and 20.15 % of the high-covered vegetation remained unchanged, while the vegetation in the northwest, northeast, southwest and southeast of the edge of the city’s third ring changed significantly. (3) The vegetation quality in urban area of Xi’an has decreased from 2011 to 2014 with 6.9 % of vegetation coverage reduced; while from 2014 to 2017, the overall vegetation quality of this area has improved with 2.1 % of the vegetation coverage increased, which was mainly attributed to urban construction and Urban Green Projects. This study not only can obtain the dynamic change information of urban vegetation quickly, but also can provide suggestions and data support for urban planning of ecological environmental protection.

Published: April 2021

Abstract
The unbalanced growth of FDI in China has seriously affected the coordinated development of China’s regional economies. Therefore, to achieve comprehensive, coordinated and sustainable development, China’s main strategic task is determining how to adopt positive and effective FDI policies to reduce this regional imbalance in FDI. The purpose of this paper is to explore and study the spillover effects of foreign direct investment (FDI) on China’s sustainable development. In this paper, based on the new political economics theory and overflow effects, comparative research and statistical research methods are adopted that combine static and dynamic analysis. Empirical research methods are combined with normative research to analyse the spillover effects of FDI on China’s sustainable development, particularly under the new situation of global crisis and the accompanying difficulties, to determine how to promote China’s FDI and the development of China’s sustainable progress strategy. The study found that in 2018, FDI in China reached a value of 13.466 billion US $, and the year-on-year growth in FDI in recent years has been basically stable at approximately 4 %. Asia is the main source of FDI in China. In 2018, the amount of FDI in Asia reached $109.1938.7 billion, accounting for 83.33 % of the total investment. Hong Kong, with its unique advantages, accounted for 72.12 % of FDI in China. FDI inflows are mainly directed to primary industry and the service sector, and the growth rate of foreign investment in 2016 in these sectors was 68.52 and 170.77 %, respectively, compared with 2007. FDI also mainly flows to the eastern region of China. By the end of 2018, the amount of foreign capital utilized in the eastern region reached $1,622.9 billion, representing 85.4 % of the aggregate FDI in China. The effect of FDI on China mainly focuses on three areas: economic growth, social development and environmental protection. FDI has brought positive spillover effects to China’s sustainable evolution, but with China’s continuous development, especially the change in its economic development mode, it has been consistently exposed to negative spillover effects.
Pollination Studies on Both Floret and Capitulum Levels in an Oil Seed Crop, Guizotia abyssinica (L.f.) Cass.

Published: April 2021

Abstract
Niger, Guizotia abyssinica (L.f.), is an important oilseed crop widely grown in Ethiopia and India, but poor pollination is one of the major constraints in achieving the yield potential of the crop. Our aim was to understand better the pollination biology and role of flower insect visitors in reproduction success. Results indicated that full anthesis occured in the morning between 06.00 and 08.00 h and pollen dehiscence eight to eleven hours after anthesis. Stigma receptivity commenced nine hours after anthesis and lasted for the next 24 h. A total of eighteen insect species representing six families visited Niger flowers, and among these, Apis florea and A. cerana were dominant. The flowers were self-incompatible as there was no seed set upon the selfing of floret and selfing of capitulum. The maximum seed set (78.33±0.14%) was noticed when flowers were allowed for open pollination and the lowest was recorded when the whole plant was caged to exclude pollinator visits (0.33±0.67). The time spent by A. cerana and A. florea was 1.35±0.48 and 1.83±0.12 seconds per floret, respectively and 9.63±0.69 and 14.9±0.94 seconds per capitulum, respectively. A. cerana and A. florea were found to be more efficient pollinators of G. abyssinica. Introducing bee colonies might greatly improve the yield, and it is also important to conserve bees in the vicinity of G. abissynica fields during the flowering period. Hence, introducing bee colonies might greatly improve the yield of Niger.
Embryo transfer as an option to improve fertility in repeat breeder dairy cows
Authors: Nowicki Arkadiusz 
Published: April 2021

Abstract
Repeat breeding is a serious reproductive disorder in dairy cattle. The causes of repeat breeding are multifactorial and there are two main mechanisms: failure of fertilisation or early embryo death, mainly due to poor quality of oocytes and an inadequate uterine environment. Many methods have been used to increase the pregnancy rate for repeat breeder cows, such as intrauterine infusion of antibacterial agents or antibiotics, hormonal treatments for oestrus synchronisation and induction of ovulation, and progesterone supplementation or induction of accessory corpus luteum; however, the results were inconsistent between studies. Embryo transfer (ET) has the capability to minimalise the effects of poor oocyte quality and unfavourable uterine environments on early embryo development during the first seven days after ovulation in repeat breeder cows, and several studies showed that ET significantly improved the pregnancy rate in this group of animals. Thus, ET can be considered an option to increase the conception rate in repeat breeder dairy cows.
Synthesis, spectroscopic and thermogravimetric interpretations of UO2(II), ZrO(II), Zr(IV), VO(II) and V(V) ciprofloxacin antibiotic drug complexes
Authors: Albedair Lamia A. 
Published: April 2021

Abstract
New five ciprofloxacin (CIP) complexes of dioxouranium(II), oxozirconium(II), zirconium(IV), oxovanadium(II) and vanadium(IV) in the proportion 1:2 have been prepared using CIP as a drug chelate with UO2(NO3)2. 6H2O, ZrOCl2. 8H2O, ZrCl4, VOSO4. xH2O and V2O5 respectively. The CIP complexes have been characterized based on the elemental analysis, molar conductance, magnetic, (FTIR & 1HNMR) spectral and thermal studies. The molar conductance studies of the synthesized complexes in DMSO solvent with concentration of 10–3 M indicate their non-electrolytic properties. At room temperature, the magnetic moment measurements revealed a diamagnetic behavior for all CIP prepared complexes. The different formulas of the new complexes can be represented as [UO2(CIP)2(NO3)2] (I), [VO(CIP)2(SO4)(H2O)] (II), [V2(O)(O2)2(CIP)2] (III), [Zr(O)(CIP)2(Cl)2] (IV), and [Zr(CIP)2(Cl)4] (V). The thermal analysis data of the complexes indicates the absence of coordinated water molecules except for vanadyl(II) complex (II). The CIP chelate is a uni-dentate ligand coordinated to the mentioned metal ion through terminal piperazinyl nitrogen. The transmission electron microscopy (TEM) investigation confirms the nano-structured form of the complexes.

Abstract
Trimethoprim drug (TMP) complexes of copper (II), cobalt (II), and nickel (II) were prepared and discussed by using elemental analysis (C, H, N analysis), magnetic, molar conductance, FTIR, Raman spectroscopy, electron spin resonance (ESR) and UV-vis spectroscopy analyses. TMP drug coordinated as a tridentate ligand towards the respected three metal ions through two nitrogen atoms of amino groups and nitrogen atom of pyrimidine ring which flanked between –NH2 groups, these assignments confirmed by spectroscopic, magnetic, ESR and thermogravimetric analyses with formulas [Cu(TMP)(H2O)3]Cl2, [Co(TMP)(H2O)3]Cl2 and [Ni(TMP) (H2O)]Cl2. Copper (II) and cobalt (II) complexes have an octahedral geometrical structure included one TMP molecule, three coordinated water molecules and two uncoordinated chlorine atoms while, nickel(II)–TMP complex has a tetrahedral geometric configuration that involved one TMP molecule, one coordinated water molecule and two uncoordinated chlorine atoms. The activation energies and other kinetic thermodynamic parameters were estimated based on the employed of the Coats-Redfern and Horowitz-Metzger equations. The nano–structured form of the synthesized TMP complexes was confirmed dependent on the transmission electron microscopy (TEM).
The Hero in the Lyrical Epic Poem Detvan in the Context of Contemporary Nationalism
Authors: Fülöpová Marta 
Published: April 2021

Abstract
The analytical-interpretative study examines the depiction of literary characters in the lyrical-epic work Detvan written by Andrej Sládkovič. It interprets the ingenious system of relations between the Slovak nation represented by the main character Martin and King Matthias Corvinus. The study notes the shifts in meaning and symbolization of relationships in this work and reveals the influence of national ideology in the creation of characters and their relations. It proves that the relationship between the king and the main character is a poetic expression of the national program, and that the story line is determined by the Slovak autostereotype of a peaceful nation. The article was written on the occasion of the 200th anniversary of Andrej Sládkovič’s birth.

Published: April 2021

Abstract
The thyroid hormones (THs) play an important role in the regulation of the rate of metabolism, affect the growth and function of different systems in the organism. The aim of this study was to assess serum concentration of total triiodothyronine (T3), total thyroxine (T4) as well as T3/T4 ratio in serum from healthy fresh water fish from Salmonidae, Acipenseridae, Cyprinidae, and Clariidae families to determine species-specific reference intervals. Mean concentrations of T3 and T4 levels varied significantly among fish. Finally, the test results show clear differences in the serum concentration of the T3 and T4 and give new insight into the thyroid hormones reference values in some commercial fresh water fish species.
