A 51-year-old female underwent recurrent open incisional hernia repair with retrorectus meshplacement. Early in the post-operative course, she developed a hernia reoccurrence secondary tobreakdown of the staple line, at the level of the posterior rectus sheath, resulting in a small bowelobstruction. This hernia could not be felt upon physical examination but was detected by imaging. The patient was promptly taken to the operating room for laparoscopic reduction of the incarceratedloop of small intestine, along with laparoscopic repair of the posterior rectus sheath defect. It iscritical for surgeons to recognize the possibility of a staple line breakdown at the level of posteriorrectus sheath early on in the diagnosis which would prompt urgent surgical intervention in thesetting of a bowel obstruction.
On interpolation functions of the twisted generalized Frobenius-Euler numbers
Y. Simsek,V. Kurt,O. Yurekli 장전수학회 2007 Advanced Studies in Contemporary Mathematics Vol.15 No.2
The main purpose of this paper is to apply Mellin transform to the generating functions of q-generalized Frobenius-Euler numbers and twisted q-generalized Frobenius-Euler numbers. By using this result, we define integral representation of twisted lH;q-function, which interpolates twisted q-generalized Frobenius- Euler numbers at negative integers. We also define twisted q-zeta functions. Furthermore, we give relation between twisted lH;q-functions and twisted q-zeta functions. We obtain new results related to the twisted lH;q-function, as well.
Applications of Euler-Seidel matrices
A. Dil,V. Kurt 장전수학회 2009 Advanced Studies in Contemporary Mathematics Vol.18 No.2
In this paper we give some applications of Euler-Seidel matrices. We use the algorithm method to investigate structures of Fibonacci and Lucas num- bers. We also proved that p (p - 1) + 1 - th row of the Euler-Seidel matrices over Zp (p is prime) is either zero sequence or it repeats the initial sequence.

Diabetes is the leading cause of chronic renal failure. Our purpose was to determine the effects of N-nitro-l-arginine (l-NNA) and an extract of Stevia rebaudiana (Bertoni) (SrB) leaves on renal function in streptozotocin-nicotinamide (STZ-NA)–induced diabetic rats. Rats were divided into seven groups. Three of these groups were controls. Diabetes was induced by STZ-NA in the other four. Diabetic rats were treated with SrB (200 mg/kg), _L-NNA (100 mg/kg), or SrB + _L-NNA for 15 days after 5–8 weeks of diabetes. At the end of the experiments, urine and blood samples were collected from the rats, and kidney tissue samples were collected with the animals under ether anesthesia. Renal filtration changes were determined by measuring urine pH, urine volume, and serum and urine creatinine. Nitric oxide synthase (NOS) activity was measured in kidney homogenates. Alterations in kidney ultrastructure were determined by electron microscopy, and histological changes were examined by hematoxylin and eosin staining. No statistical differences were observed in urine creatinine or creatinine clearance. Even so, we observed higher NOS activity in SrB-treated diabetic rats. SrB-treated diabetic rats had less mitochondrial swelling and vacuolization in thin kidney sections than other diabetic groups. The control groups showed normal histological structure, whereas in the diabetic groups, membrane thickening, tubular epithelial cells, and cellular degeneration were observed. Thus, SrB has beneficial effects on diabetes compared with _L-NNA. Our results support the validity of SrB for the management of diabetes as well as diabetes-induced renal disorders.

In this paper, explicit generalizations of Hardy-Berndt sums, which are arising in the transformation formula of the logarithms of the classical theta functions, are de¯ned. The connection between generalized Dedekind sums is also given, and some ¯nite and in¯nite series representations are obtained in terms of trigonometric functions and Hurwitz's zeta function. By using contour integration, the reciprocity laws and some relations for these generalized sums are given as well.
Twisted Dedekind type sums associated with Barnes' type multiple Frobenius-Euler l-functions
M. Can,M. Cenkci,V. Kurt,Y. Simsek 장전수학회 2009 Advanced Studies in Contemporary Mathematics Vol.18 No.2
The aim of this paper is to construct new Dedekind type sums. We construct generating functions of Barnes' type multiple Frobenius-Euler numbers and polynomials. By applying Mellin transformation to these functions, we de¯ne Barnes' type multiple l-functions, which interpolate Frobenius-Euler numbers at negative integers. By using generalizations of the Frobenius-Euler functions, we de¯ne generalized Dedekind type sums and prove corresponding reciprocity law. We also give twisted versions of the Frobenius-Euler polynomials and new Dedekind type sums and corresponding reciprocity law. Furthermore, by using p-adic q-Volkenborn integral and twisted (h,q)-Bernoulli functions, we construct p-adic (h,q)-higher order Dedekind type sums. By using relation between Bernoulli and Frobenius-Euler functions, we also de¯ne analogues of Hardy-Berndt type sums. We give some new relations related to to these sums as well.

I. N.. Cangul,H. Ozden,V. Kurt,Y. Simsek 장전수학회 2009 Advanced Studies in Contemporary Mathematics Vol.19 No.1
Main purpose of this paper is to study on higher-order w-q-Genocchi numbers and polynomials by using p-adic q-deformed fermi- onic integral on Zp. We derive some identities related to higher-order w-q- Genocchi numbers and polynomials. We also give interpolation functions of these numbers and polynomials.
