Aim. To study the role and degree of influence of various clinical factors on osseointegration and the success of direct and delayed dental implantation using implant systems with different surface microstructure.
Material and methods. Implant systems with different surface microstructures were used for the clinical study: Alfa Bio, Mis, Astra Tech, Dentium, Osstem, Antogher and Humana Dental.
The study included 414 patients aged 20 to 70 years. All patients involved in the study were divided into two groups. The first group consisted of 109 patients who, after extraction, underwent direct implantation into the socket of the extracted tooth, followed by immediate loading. The second group, out of 305 patients, underwent delayed implantation. A total of 1302 implants were installed. Before the start of surgery, all patients underwent a thorough clinical and laboratory, X-ray and functional examination, as well as computed tomography. Dynamic observation was carried out on the basis of clinical, radiological and functional methods. In the course of treatment, starting from the moment of implantation at different times, the devices "Periotest" and "Osstel Mentor" were used to determine the stability of the implants and the dynamics of the quality of the osseointegration process.
Results. The study found that implants placed in the lower jaw had higher success rates than implants placed in the upper jaw. There was no direct relationship between the length and diameter of implants and their survival rate. However, implants with a longer length and diameter are the best option for increasing primary stability. The analysis of implantation methods showed no statistically significant difference between the percentage of implant survival during immediate and delayed implantation. The highest percentage of implantation failures was noted with simultaneous implantation and sinus lifting, as well as with a horizontal increase in bone tissue volume.
Conclusions. The findings of the study demonstrated that the long-term success of dental implantation depends on a combination of many factors, including bone volume and quality, shape, geometry, implant design, and surface microstructure.

Published: May 2021

Objective: Sleep Disordered Breathing (USB) is one of the most common childhood disorders ranging from simple snoring to obstructive sleep apnea (OSA), and most common cause of it is the adenotonsillar hypertrophy (ATH). Otitis Media with Effusion (OME) is another important problem in children with USB due to ATH. The aim of this study was to evaluate the possible risk factors for the development of EOM in children with USB due to ATH.
Material and Methods: 171 pediatric patients with ATH-related snoring and sleep apnea complaints were included in the study. The patients were divided into two groups. Group 1: patients with ATH + OME and Group 2: patients with ATH alone. A pre-operative standard questionnaire was used to assess USB severity. Twenty-one different parameters were evaluated for both groups.
Results: Age, sex, exposure to tobacco smoke, cow milk exposure before 12 months, breast milk only for at least 6 months, duration of symptoms, USB symptom scores, history of recurrent tonsillitis, adenoid / nasopharynx (AN) ratio, tonsil size, body mass index (BMI), hemoglobin (Hb) level, hematocrit (Hct) ratio, mean platelet volume (MPV), eosinophil ratio, neutrophil-lymphocyte ratio (NLR), thyroid function tests (TSH, fT4), folate and vitamin B12 levels were evaluated. There was no statistically significant difference between these parameters except BMI. BMI values were 16.08 ± 1.96 in Group 1 and 17.11 ± 2.81 in Group 2, respectively (p: 0.006).
Conclusion: Many different parameters were evaluated for EOM, a multifactorial disease. Among the groups, only BMI was different. Further study is required to identify risk factors for the development of EOM in patients with ATH.

Panorama das cooperativas de crédito no Brasil
Authors: De Souza Leonardo Rafael 
Published: May 2021

O presente estudo apresenta um panorama sobre a realidade do cooperativismo de crédito brasileiro desde a sua origem rural e solidária até a atual tendência de bancarização da sua atividade em detrimento dos aspectos humano e social que orientam com igual importância todo e qualquer empreendimento cooperativo. Ao discorrer ainda sobre a consolidação das bases legais das sociedades cooperativas de crédito no Brasil, este ensaio busca identificar o processo de transformação do pensamento cooperativo de crédito brasileiro, atualmente tendente a um processo de «companização» da sua legislação e funcionamento. Ao final reflete-se —a partir de exemplos e destaques normativos— sobre os riscos deste fenômeno para as perspectivas das cooperativas de crédito à luz da identidade cooperativa.

Authors: Abdel-Wahab Tamer Ibrahim , Abdel-Wahab Eman Ibrahim 
Published: May 2021

Background: Broomrape (Orobanche crenata Forsk.) is a major biotic stress of faba bean and affects the yield adversely. The impact of intercropping to curb the spread and progress of parasite was tested by using two faba bean cultivars under heavily soil infested conditions of broomrape. The present study was aimed to evaluate intercropping of fenugreek, flax, garlic or radish with two faba bean cultivars on broomrape incidence to increase faba bean yield, land usage and economic return in heavy soil infestation of broomrape. Methods: This study was carried out at Giza Agricultural Research Station (Lat. 30°00′30″ N, Long. 31°12′43″ E, 26 m a.s.l), Agricultural Research Center, Giza, Egypt. During winter seasons of 2017/2018 and 2018/2019, the treatments were the combinations of two faba bean cultivars (Nubaria 1 and Nubaria 2) and four intercrops (fenugreek, flax, garlic and radish), as well as sole plantings of all the tested crops under heavily infestation of broomrape were tested in field conditions. A split-plot design with three replicates was used. Faba bean cultivars were assigned in the main plots and intercropping and sole plantings of faba bean were arranged in sub plots. Result: Results showed that Nubaria 2 had two mechanisms to broomrape offensive, mainly including cell wall build-up and stamping of vascular tissues. It also had higher soil oxalic and ascorbic acid concentrations than Nubaria 1. Sole Nubaria 1 rhizosphere had higher soil formic acid whereas, fenugreek + Nubaria 2 had higher soil oxalic, ascorbic and salicylic acids concentrations in faba bean rhizosphere. Lower number of spikes per m2 and their dry weight per m2 were obtained by radish + Nubaria 2 followed by flax + Nubaria 2. Radish + Nubaria 2 recorded higher land equivalent ratio and economic return followed by flax + Nubaria 2. Growing one row of radish or flax between two rows of Nubaria 2 in ridges 60 cm width could be an integrated control strategy to increase faba bean productivity, land usage and economic return under heavily soil infested with broomrape.

Dyes are widely used for various manufacturing processes. However, the high use of synthetic dyes has resulted in pollution and health problems. To overcome this problem, one way that can be done is to return to using natural dyes. Natural dyes can be obtained from various plants, one of which is the Indonesian mangrove plant (Rhizophora mucronata). This research has succeeded in extracting natural dyestuffs from mangrove bark using the microwave-assisted extraction method. Mangrove wood extraction was carried out with solvents, namely distilled water and ethanol 96%, which was optimized based on the ratio of sample mass to volume of solvent and extraction power. The results showed that qualitatively the mangrove extract contained tannins, flavonoids, and quinones as compounds that gave chocolate color. The color resistance of mangrove extracts is very strong in textiles under alkaline conditions. Based on the results of extraction optimization, the optimum conditions were obtained at a ratio of 0.067 g/mL of 96% ethanol at 380 watts of power, with a yield percentage reaching 53.053%. Keywords: extraction, mangrove wood, microwave Zat warna banyak digunakan untuk berbagai proses manufaktur. Namun, tingginya penggunaan zat pewarna sintetis mengakibatkan pencemaran dan masalah kesehatan. Untuk mengatasi masalah tersebut, salah satu cara yang dapat dilakukan adalah kembali menggunakan zat warna alami. Zat pewarna alami dapat diperoleh dari berbagai tumbuhan, salah satunya tanaman bakau Indonesia (Rhizophora mucronata). Penelitian ini telah berhasil melakukan ekstraksi zat warna alami kulit kayu bakau dengan metode microwave-assisted extraction. Ekstraksi kayu bakau dilakukan dengan pelarut yaitu akuades dan etanol 96% yang dioptimasi berdasarkan rasio massa sampel–volume pelarut dan daya ekstraksi. Hasil penelitian menunjukkan bahwa secara kualitatif ekstrak kayu bakau mengandung tanin, flavonoid, dan kuinon sebagai senyawa pemberi warna coklat. Ketahanan warna ekstrak kayu bakau sangat kuat pada bahan tekstil pada kondisi basa. Berdasarkan hasil optimasi ekstraksi, kondisi optimum didapatkan pada rasio massa sampel-volum pelarut sebesar 0,067 g/mL dan daya sebesar 380 Watt sehingga diperoleh persentase yield mencapai 53,053%.

Published: May 2021

ABSTRACTThere has long been debate about the origin of long, linear, isolated shallow marine sandstones. In the 1980s these were routinely interpreted as wave- or tide-modulated shelf sandstones. With the advent of sequence stratigraphy, many of these sandstones were reinterpreted as top-truncated forced-regressive to lowstand delta or shoreface, inviting the question regarding whether the concept of a shelf sandstones remain a viable depositional model. More recent syntheses demonstrate that shelf sands tend to be derived by reworking of underlying sediment through transgressive erosion and show varying levels of detachment and reworking into discrete ridges and bars by wave and tidal processes as they become more evolved.The Late Cretaceous Tocito Sandstone in the Western Interior Seaway, which overlies the regressive Gallup Formation, is a candidate for a transgressive shelf sandstone. In this study, we present detailed facies analysis, based on sedimentological sections measured from well-exposed outcrops of the Tocito Sandstone and its related stratigraphic units in northwest New Mexico, USA. With high-resolution sequence stratigraphic control, facies analysis, detrital-zircon anatomy, and petrographic analysis are integrated to investigate the sequence stratigraphic evolution and depositional processes of the Tocito Sandstone. Detrital zircons indicate that the Tocito, Torrivio, and Gallup deposits are derived from different source areas, and therefore imply separate sequence stratigraphic origins. The Tocito Sandstone is interpreted to have been deposited as shelf sand ridges in retrogradational estuarine to drowned-barrier-system environments with tidal and wave influence, characterized by intense bioturbation. The Tocito was deposited in an overall transgressive systems tract and sourced from reworking of the underlying Torrivio and Gallup units through processes of transgressive erosion.

Abstract
Aim: The present study seeks to provide insight into the management of patients with chronic kidney disease (CKD) infected with COVID-19.Material and methods: Patients with COVID-19 were included in the study if they met the inclusion criteria. 78 eligible patients were divided into four groups. After reviewing clinical charts, nursing records, laboratory findings, radiological reports and other medical records of CKD patients with COVID-19 confirmed infection, clinical presentation, laboratory data, radiology findings, and results were extracted from documented medical records using data collection forms. laboratory tests were performed again before discharge. Independent t-test, paired t-test, and chi-square were used to compare the clinical features of patients with COVID-19. A P< 0.05 was considered to indicate statistical significance. All the statistical analyses were performed by the SPSS. v 26.0.Results: Hypertension (72.5%), diabetes (63.8%), and Cardiovascular disease (38.2%) were the most common among patients, respectively. Among all participants, 40 (52.6%) patients died. The most common symptom was dyspnea (56.6%), followed by dry cough (38.7%). Comparison of blood, inflammatory, biochemical, and clinical indices between the four groups in patients show that LDH (P=0.022), AST (P=0.038), and ALT (P= 0.004) indices were significantly different between groups of patients. According to the results in Table 3, Unilateral ground-glass opacity (GGO) in the radiological findings of the Non-dialysis CKD group was significantly (P=0.50) higher than the other groups.Conclusion: It can be concluded that CKD is an important factor that can cause poor prognosis in COVID-19 patients.

Abstract
BackgroundKidney involvement in COVID-19 may manifest as acute kidney injury (AKI). This study aimed to analyze and compare AKIs in different stages of COVID-19.Methods1056 hospitalized COVID-19 patients were retrospectively evaluated and 383 of them met the inclusion criteria. Eighty-nine patients who developed AKI, but didn’t have prior kidney diseases were involved in the final analysis. Patients were classified into three groups, those who had AKI on admission, those who developed AKI in the first week and those who developed AKI starting from the 7th day. Electrolytes, acid-base status and changes in the inflammatory markers were compared. ResultsAKIs that were seen on hospital admission day were generally transient. Patients who developed AKI after the 7th day had higher peak CRP and D-dimer levels and lower nadir lymphocyte counts (p=0.000, 0.004 and 0.003 respectively). AKI that developed later was more related to immunologic response and had significantly higher mortality, reaching as high as 44% after 7th day. Hematuria and proteinuria (p=0.001; OR: 2.4; 95% CI: 1.4 – 3.8 and p=0.015; OR: 4.34; 95% CI: 1.3 – 14.3 respectively) were more common in patients who died. Hypernatremia (p=0.000, OR: 6.5; 95% CI:3.0 – 13.9) and hyperchloremia (p=0,002, OR:3,8; 95%CI: 1,7 – 8,4) were also observed more often in patients who died.ConclusionsAKI in COVID-19 is not of one kind. When developed, AKI should be evaluated in conjunction with the disease stage and possible etiologies. AKI that develops later has worse prognosis and is more related to electrolyte abnormalities even in patients with normal kidney functions.

Abstract
Background/Objectives: The present study identified the independent risk factors of R1 resection in pancreaticoduodenectomy (PD) and distal pancreatosplenectomy (DP) for patients with pancreatic ductal adenocarcinoma (PDAC).Methods：Consecutive patients who were operated from 1st December 2017 to 30th December 2018 with curative intent were analyzed retrospectively. A standardized pathological examination with digital whole-mount slide images (DWMSIs) was utilized for the resection margin status. R1 was defined as microscopic tumor infiltration within 1 mm to the resection margin. The potential risk factors of R1 resection for PD and DP were analyzed separately by univariate and multivariate logistic regression analyses. Results：For the 240 patients who underwent PD, and the 146 patients who underwent DP, the R1 resection rates were 30.8% and 35.6 %, respectively. Univariate analysis on risk factors of R1 resection for PD were tumor location, absence of tumor necrosis, N staging, and TNM staging; while those for DP were perineural invasion, T staging, and TNM staging. Multivariate logistic regression analysis showed the location of tumor in the neck and uncinate process, and N1/2 staging were independent risk factors of R1 resection for PD; while those for DP were T3/4 staging. Conclusions：The clarification of the risk factors of R1 resection might clearly make surgeons take better decisions on surgical strategies for different surgical precedures in patients with PDAC.

Abstract
The emergent cooling technologies based on the caloric effect provide a green alternative to the conventional vapor-compression one which brings about the serious environment problem. However, the existing caloric materials are much inferior to their traditional counterparts in cooling performance. Here we report the colossal barocaloric effect in liquid-solid-transition materials, i.e. n-alkanes. Their excellent cooling performance is superior to those for existing caloric materials and comparable to those of traditional refrigerants. Theoretical calculations suggest the liquid state n-alkanes has huge configuration entropy characterized by large dispersion of bond lengths. Appling pressure significantly reduces the configuration entropy and eventually induces the liquid-solid-transition, leading to the colossal barocaloric effect. This work provides promising refrigerants for caloric cooling technology, and opens a new avenue for exploring colossal barocaloric materials.

Abstract
Background

Gallbladder stone diseases being common disorder, prior studies have identified an association between gallstones and abnormal lipids, type 2 diabetics have higher rates of significant abnormalities in lipid metabolism, so the prevalence of dyslipidemia may be higher in gallstone disease patients with type 2 diabetes mellitus (T2DM) than in the general population. This study aimed to compare the serum lipid and lipoprotein abnormalities between gallbladder stone patients who have T2DM and controls in China.
Methods

Retrospective analysis of serum lipid and apolipoprotein levels in patients aged 40 years and older with gallbladder stone combined with T2DM, T2DM, gallbladder stone, and a normal group of 407 individuals in four groups. 135 cases with gallbladder stones combined with T2DM were compared with 102 cases with T2DM, 119 cases with gallbladder stones, and 51 normal individuals respectively among four groups. Triglyceride (TG), total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL), very low-density lipoprotein (VLDL), serum apolipoprotein (apo) AI (ApoAI), apolipoprotein (apo) B (ApoB) and their ratio (ApoAI/ApoB) were collected from the four groups and compared. One-way ANOVA and nonparametric tests (Kruskal-Wallis H tests) were used to compare groups. P < 0.05 was considered statistically significant.
Results

Compared to three control groups, the patients over 40 years old with gallbladder stone combined with T2DM had significant abnormal changes in lipids: the LDL and APoB levels were significantly raised in patients with gallbladder stones combined with T2DM (P < 0.05), and in males LDL levels were significantly higher in gallbladder stones patients with concomitant T2DM (P < 0.05).
Conclusions

The study showed that LDL and APoB levels were statistically significant in patients over 40 years of age with concurrent gallbladder stone disease and T2DM, with male patients having significantly higher LDL levels but no statistically significant parameters were found in female patients.
