Abstract:Aim: \nIn this article we present a rare complication of laparoscopic adjustable gastric banding: Emphysematous gastritis with gastric necrosis secondary to superior mesenteric artery syndrome. Which unlike the rest of the articles, it is explained the cause that led to this syndrome. \nCase presentation:\nA 29 –year-old French woman with a bariatric history (BMI= 55.9; Height=166cm, weight = 154) underwent laparoscopic gastric banding for morbid obesity and was emergency re-operated for band slippage and regained weight. In 2017 she experienced acute abdominal pain associated with nausea without being able to vomit for which she was admitted to the emergency hospital. The computed tomographic revealed a massive distension of her stomach and duodenum, pneumatosis and portal venous gas. A junction syndrome at 3rd level of the duodenum linked to a superior mesenteric artery syndrome. Surgery treatment was needed considering the massive gastric necrosis for which a total gastrectomy with Roux en Y eophagojejunostomy anastomosis was performed. Due to fear of a possible rupture of the duodenum remaining part may occur, a 2cm latero-later duodenojejunostomy anastomosis was performed to ensure a good biliary drainage of the duodenum. The patient was discharged from the hospital within 10 days.\nConclusion\nThe fastest way to treat the patient was to prescribe her parenteral nutrition with the intention of gaining weight but because gastric emptying cannot be achieved the SMA can become a lethal complication due to the gastric necrosis.
Abstract:The paper presents the elucidation of the concept of migration and theories describing the process of migration, determines the issue of openness to immigration and presents its theoretical explanation. The factors determining the attitude towards immigration and immigrants are examined by dividing the factors into the main groups of economic and social-cultural factors. Analysis of immigration trends in Lithuania is presented. The paper aims to develop theoretical framework for assessment of employer openness to immigrants by revealing the main factors determining the attitudes of employers to labour immigrants and apply this framework in order to determine whether it is possible to integrate labour immigrants into the labour market in Lithuania.
Abstract:The Coronavirus (COVID-19) pandemicmanaged to overturn the entire organization of the medical system and changed all medical protocolsincluding surgical ones. Elective and otherroutine operations have been cancelled or postponedwhichled to congestionand hazard between long-established appointments andnew appointments during the COVID-19 pandemic. Small hernias repair should be carefully done respecting all the reported recommendationsfor Coronavirus (COVID-19).
Abstract:Surgeons have sufficient knowledge and should be motivated regarding adopting novel surgical devices, techniques, principles in order to provide the best care for the patients. Not everyone can become a great surgeon, but a great surgeon can come from anywhere. The same principle can be applied also in innovation. Surgery involves not only knowledge, concentration and precision but also imagination and creativity and if the imagined device can facilitate your work why not design it. The role of this article is to help any surgeon regardless of which hospital his working: poor hospital with lack of materials or very developed one with everything a surgeon needs. The device created by us is a very cheap one and any hospital can afford it. We have created a prototype (surgical device for safe and fast surgical swans count) that can be diversified or improved by using electronic technology. The role of this surgical device is to facilitate the collection of the used surgical swabs and to reduce the time allocated to the surgical swabs counting, which implies reducing surgical time.
Abstract:We have demonstrated that LC3Bylation, a covalent modification of target protein lysine residue with the microtubule-associated protein 1 light chain 3B (LC3B) by Atg16L complex as a positive feedback regulation loop, is required for the late autophagy process, instead of its phosphatidylethanolamine (PE) lipidation which is responsible for elongation and recruitment to an autophagosome. We observed that the expression of PIG3 (p53-inducible gene 3; quinone oxidoreductase; PIG3) was enhanced up to 11 times in LC3B overexpression cell line than in its background HEK293 cells based on RNA sequencing analysis. Consequently, we observed that LC3Bylation on 257K in 256FKRG259 of PIG3 was only recognized by site directed mutagenesis. With PIG3 expression alone, cell autophagy activity was enhanced 11 times. These results suggest that PIG3 is feed-backed by its own autophagy machinery through LC3Byaltion to recruit into the autophagosome, eventually enhancing autophagy activity. PIG3 as one target protein of LC3Bylation can enhance cell autophagy and oncogenic activity without showing TP53 expression change.
Abstract:A snowpit study was conducted in the vicinity of the Jang Bogo Station (JBG).\nSeasonal variations of the isotopic and chemical compositions of snowpits can provide useful\ntools for dating the age of the snowpit and examining the sources of aerosol. Distinct seasonal\nvariations of stable water isotopes of the snowpit were observed, with a slope of 8.2 from the\nlinear isotopic relationship between oxygen and hydrogen, which indicates that the snow\naccumulated during three years without a significant post-depositional process. Based on the\nseasonal layers with δD and δ18O maxima and minima, it was determined that the snowpit\ncontained snow deposited over a three-year period (2008–2010). The positive correlations (r >\n0.85) between sea-salt ions and the values of the MSA and nssSO4\n2– warm period indicate the\ncontribution of an oceanic source. This study will support further investigations in this region.
Abstract:The main objective of this research was the realization of advanced oxide materials, obtained by technologies consistent with sustainable development, materials that are used in special operating conditions (the existence of a temperature difference of over 10000C between the mold wall and steel crust) as in the case of continuous casting of steel. These are the lubricating powders for the crystallizer, in the composition of which the blast furnace slag was harnessed as a basic raw material.
Abstract:Background: Lichen planus (LP) carries the increased risk of cardiovascular events as it is a chronic inflammatory disease. Arrythmias are the main risk factors especially in terms of cardiovascular events. We aimed in this study to determine in the patients with LP the relationship between total atrial conduction time, P-wave dispersion and the left atrium global strain, which are the predictors of atrial arrythmias most commonly affecting the society. \nMethods: 40 patients as a control group and 40 patients with lichen planus were included in this study. Conventional 2D echocardiography, assessment of left atrial function has been performed by measuring volumes. The average peak values of left atrial strain during the left ventricular systole were measured (LAGLS). Total atrial conduction time (TACT) values were assessed by 2D tissue doppler imaging. \nResults: The global peak systolic LA myocardium strain during the left ventricular systole (LAGLSRs) and the global peak negative LA myocardial strain rate during the early ventricular diastole (LAGLSRe) values were significantly lower in the patients with LP in proportion to the control according to the strain measurements (1.7±0.07 vs 1.9±0.1 % p=0,001; 1.23±0.04 vs 1.2±0.08 s-1 p=0,001 ) respectively. When considered in terms of the atrial conduction features, total atrial conduction time (TACT) value was found significantly longer (102.6±6.3 ms) in the patients with LP in proportion to the control group (96.3±5.3 ms. p=0,001). \nConclusions: Our study demonstrated that the subclinical cardiac involvement in LP could be predicted by the prolonged TACT and the impaired left atrial myocardial deformation values
