Uğur Bozkaya
Efficient implementations of analytic gradients for the orbital-optimized MP3 and MP2.5 and their standard versions with the density-fitting approximation, which are denoted as DF-MP3, DF-MP2.5, DF-OMP3, and DF-OMP2.5, are presented. The DF-MP3, DF-MP2.5, DF-OMP3, and DF-OMP2.5 methods are applied to a set of alkanes and noncovalent interaction complexes to compare the computational cost with the conventional MP3, MP2.5, OMP3, and OMP2.5. Our results demonstrate that density-fitted perturbation theory (DF-MP) methods considered substantially reduce the computational cost compared to conventional MP methods...

BACKGROUND: Renal ischemia-reperfusion (IR) leads to alterations of tubular epithelial cells, interstitial microvasculopathy and endothelial cell dysfunction in peritubular capillaries. Although dextrans have deteriorative effects on healthy kidney, their favorable effects on post-ischemic microvascular disturbances have been demonstrated. Therefore, we aimed to investigate in vivo effects of systemic Dextran 70 administration in kidney tissue with ischemia-reperfusion injury. METHODS: Twenty-one rats were allocated as sham, IR and IR+ Dextran 70 treatment groups...

Adult survivors of childhood cancers are more prone to developing poor reproductive and obstetrical outcomes than their siblings and the general population as a result of previous exposure to chemotherapy and radiation during childhood. Chemotherapy drugs exert cytotoxic effects systemically and therefore can damage the ovaries, leading to infertility, premature ovarian failure, and, to a lesser extent, spontaneous abortions. They have very limited or no deleterious effects on the uterus that can be recognized clinically...

Previous studies have evidenced that inflammation and endothelial dysfunction have a crucial role in erectile dysfunction (ED). Increased monocyte count or activity and lower high-density lipoprotein cholesterol (HDL-C) levels have been associated with inflammation. The monocyte to HDL-C ratio (MHR) is a recently emerged indicator of inflammation. We aimed to investigate the relationship between MHR and ED. In this retrospective study, a total of 120 patients were enrolled, 60 of them having ED and 60 having a normal erectile function...

Virus-like particles (VLPs) displaying foreign antigens have become an important tool in vaccination including the induction of immune responses against self-antigens. Claudin 6 (CLDN6) has been identified as tumor-associated antigen and is therefore a potential target for tumor vaccination strategies. However, as tetra-membrane spanning protein its incorporation into VLPs while preserving a native fold is challenging. Here, we attempted the incorporation of a panel of engineered CLDN6 variants into the membrane of retrovirus-derived VLPs...

Aortic intramural hematoma (IMH) is a variant of acute aortic syndrome, which can be life-threatening. Ascending aorta IMHs, particularly accompanied by penetrating aortic ulcer (PAU), can cause dissection, rupture, and cardiac tamponade. Therefore, early surgical treatment is recommended for IMHs of the ascending aorta. Herein, we present the case of a 60-year-old male patient who was on warfarin sodium treatment and in whom an IMH localized to the arcus aorta was detected incidentally via computed tomography, with the suspicion of pulmonary embolism, and an endovascular stent graft was inserted into the arcus aorta...
