1Adverse effects of oral antiviral therapy in chronic hepatitis B显示文摘Oral nucleoside/nucleotide analogues(NAs) are currently the backbone of chronic hepatitis B(CHB) infection treatment. They are generally well-tolerated by patients and safe to use. To date, a significant number of patients have been treated with NAs. Safety data has accumulated over the years. The aim of this article is to review and update the adverse effects of oral NAs. NAs can cause class adverse effects(i.e., myopathy, neuropathy, lactic acidosis) and dissimilar adverse effects. All NAs carry a 'Black Box' warning because of the potential risk for mitochondrial dysfunction. However, these adverse effects are rarely reported. The majority of cases are associated with lamivudine and telbivudine. Adefovir can lead to dose- and time-dependent nephrotoxicity, even at low doses. Tenofovir has significant renal and bone toxicity in patients with human immunodeficiency virus(HIV) infection. However, bone and renal toxicity in patients with CHB are not as prominent as in HIV infection. Entecavir and lamivudine are not generally associated with renal adverse events. Entecavir has been claimed to increase the risk of lactic acidosis in decompensated liver disease and high Model for End-Stage Liver Disease scores. However, current studies reported that entecavir could be safely used in decompensated cirrhosis. An increase in fetal adverse events has not been reported with lamivudine, telbivudine and tenofovir use in pregnant women, while there is no adequate data regarding entecavir and adefovir. Further long-term experience is required to highlight the adverse effects of NAs, especially in special patient populations, including pregnant women, elderly and patients with renal impairment.Bircan Kayaaslan Rahmet Guner 2017World Journal of Hepatology2017,9,5:17
2Rare etiology of mechanical intestinal obstruction: Abdominal cocoon syndrome显示文摘Abdominal cocoon syndrome is a rare cause of intestinal obstruction with unknown etiology. Diagnosis of this syndrome, which can be summarized as the small intestine being surrounded by a fibrous capsule not containing the mesothelium, is difficult in the preoperative period. A 47-year-old male patient was referred to the emergency department with complaints of abdominal pain, nausea, and vomiting for two days. The abdominal computed tomography examination detected dilated small intestinal loops containing air-fluid levels clustered in the left upper quadrant of the abdomen and surrounded by a thick, saclike, contrast-enhanced membrane. During exploratory surgery, a capsular structure was identified in the upper left quadrant with a regular surface that was solid-fibrous in nature. Ab-dominal cocoon syndrome is a rarely seen condition, for which the preoperative diagnosis is difficult. The combination of physical examination and radiological signs, and the knowledge of 'recurrent characteristics of the complaints' that can be learned by a careful history, may be helpful in diagnosis.Yener Uzunoglu Fatih Altintoprak Omer Yalkin Yasemin Gunduz Guner Cakmak Orhan V Ozkan Fehmi Celebi 2014World Journal of Clinical Cases2014,2,11:13
3Exp-Function Method and Fractional Complex Transform for Space-Time Fractional KP-BBM Equation显示文摘In the present article, He's fractional derivative, the ansatz method, the(G′/G)-expansion method, and the exp-function method are used to construct the exact solutions of nonlinear space-time fractional Kadomtsev–Petviashvili–Benjamin–Bona–Mahony(KP-BBM). As a result, different types of exact solutions are obtained. Also we have examined the relation between the solutions obtained from the different methods. These methods are an efficient mathematical tool for solving fractional differential equations(FDEs) and it can be applied to other nonlinear FDEs.Ozkan Guner 2017Communications in Theoretical Physics2017,67,8:10
4Bright and dark soliton solutions for some nonlinear fractional differential equations显示文摘In this work, we propose a new approach, namely ansatz method, for solving fractional differential equations based on a fractional complex transform and apply it to the nonlinear partial space–time fractional modified Benjamin–Bona–Mahoney(m BBM) equation, the time fractional m Kd V equation and the nonlinear fractional Zoomeron equation which gives rise to some new exact solutions. The physical parameters in the soliton solutions: amplitude, inverse width, free parameters and velocity are obtained as functions of the dependent model coefficients. This method is suitable and more powerful for solving other kinds of nonlinear fractional PDEs arising in mathematical physics. Since the fractional derivatives are described in the modified Riemann–Liouville sense.Ozkan Guner Ahmet Bekir 2016Chinese Physics B2016,25,3:6
5Singular and non-topological soliton solutions for nonlinear fractional differential equations显示文摘In this article, the fractional derivatives are described in the modified Riemann–Liouville sense. We propose a new approach, namely an ansatz method, for solving fractional differential equations(FDEs) based on a fractional complex transform and apply it to solve nonlinear space–time fractional equations. As a result, the non-topological as well as the singular soliton solutions are obtained. This method can be suitable and more powerful for solving other kinds of nonlinear fractional FDEs arising in mathematical physics.Ozkan Guner 2015Chinese Physics B2015,24,10:3
6Density-Dependent Conformable Space-time Fractional Diffusion-Reaction Equation and Its Exact Solutions显示文摘In this article, a special type of fractional differential equations(FDEs) named the density-dependent conformable fractional diffusion-reaction(DDCFDR) equation is studied. Aforementioned equation has a significant role in the modelling of some phenomena arising in the applied science. The well-organized methods, including the exp(-φ(ε))-expansion and modified Kudryashov methods are exerted to generate the exact solutions of this equation such that some of the solutions are new and have been reported for the first time. Results illustrate that both methods have a great performance in handling the DDCFDR equation.Kamyar Hosseini Peyman Mayeli Ahmet Bekir Ozkan Guner 2018Communications in Theoretical Physics2018,69,1:2
