Investigation of the Relationship Between Trefoil Factor Family Peptides and Sinonasal Inflammation.

The trefoil factor family (TFF) is a relatively new family of peptides. In some studies, an association between trefoil factors and inflammatory diseases of the nasal and paranasal sinuses has been suggested. However, it is still not clear whether there is a relationship between trefoil peptides and inflammation of the respiratory tract.

A Chemically Induced Experimental Colitis Model with a Simple Combination of Acetic Acid and Trinitrobenzene Sulphonic Acid.

Background: It was aimed to induce a new experimental colitis model by using acetic acid and trinitrobenzene sulphonic acid together and to investigate the severity of inflammation biochemically and histopathologically in comparison with other models.

Methods: Fifty-six Wistar albino male rats were randomly divided into 4 groups as control, acetic acid, trinitrobenzene sulphonic acid, and combined groups, and the animals were sacrificed following the induction of colitis on the third day and on the seventh day. The serum amyloid A and myeloperoxidase were tested in plasma samples, and the tumor necrosis factor-alpha, interleukin 33, and ST2 were assayed in colon tissue samples with enzyme-linked immunosorbent assay in addition to histopathological examination.

Platelet-Rich Plasma for Skin Graft Storage: An Experimental Study Using Rabbit Ears.

Background: Storage of surplus grafts for later use is one of the standard procedures used in plastic surgery. For the delayed use of skin grafts, various methods and media have been investigated for short-term storage. This study aimed to investigate the effect of platelet-rich plasma (PRP) skin graft storage on the survival of skin grafts obtained from rabbit ears.

Effects of device variables to radiofrequency (RF) applications.

RF devices have frequency, power and duration setting options, it is important to make sure that the device meets the targeted values at the head output. This study was made to evaluate the RF device output value accuracy and the effects of different frequencies on the tissue heat levels. RF was applied to invitro tissues obtained from surgical operations, and invivo tissues during operations.

Propofol attenuates cytokine-mediated upregulation of expression of inducible nitric oxide synthase and apoptosis during regeneration post-partial hepatectomy.

Purpose:: To determine the effects of propofol and ketamine anesthesia on liver regeneration in rats after partial hepatectomy (PHT).

Methods:: Male Wistar albino rats were assigned randomly to four groups of 10. Anesthesia was induced and maintained with propofol in groups 1 and 2, and with ketamine in groups 3 and 4.

The Effectiveness of Porcine Dermal Collagen (Permacol(®)) on Wound Healing in the Rat Model.

Porcine acellular dermal collagen (PDC), which is a biological material derived from processing porcine dermis, has already been used for urologic, gynecologic, plastic, and general surgery procedures up to now. The aim of this study is to investigate the effectiveness of PDC on wound healing as a dermal substitute in the rat model. Twenty Wistar albino rats were divided into two groups.

Comparison of the efficacy and histopathological effects of three hemostatic agents in a partial nephrectomy rat model.

Purpose: The major complications of partial nephrectomy are bleeding and urine leakage. While various hemostatic agents are used to control bleeding, the histopathological characteristics of these hemostatic agents have not been investigated adequately. We aimed to investigate and compare the histopathological and hemostatic effects of local hemostatic agents in a partial nephrectomy rat model.

A retrospective multicenter evaluation of cutaneous melanomas in Turkey.

Background: We defined melanoma distribution in a large series of Turkish patients and evaluated the prognostic parameters of melanomas.

Materials And Methods: A total of 1574 patients' data was retrospectively collected at 18 centers in Turkey. Demographic characteristics were questioned and noted.

The effect of microneedling with a roller device on the viability of random skin flaps in rats.

Background: In a random pattern skin flap, distal flap necrosis occurs as a result of inadequate blood flow. Microneedling with a handheld roller device is a new treatment modality, especially for facial rejuvenation. In this study, the authors used microneedling to increase flap viability.

Oral high-dose ankaferd administration effects on gastrointestinal system.

Background And Aims: Ankaferd Blood Stopper (ABS) is a herbal extract obtained from five different plants. It has a therapeutic potential for the management of external hemorrhage and controlling gastrointestinal bleeding. However, ABS's effects are not unknown on gastrointestinal systems.

Beneficial effects of Ankaferd Blood Stopper on dermal wound healing: an experimental study.

Ankaferd Blood Stopper(®) (ABS) is a folkloric medicinal plant extract used as a haemostatic agent in traditional Turkish medicine. The aim of this study was to investigate the efficacy of ABS on the healing of dermal wounds in a rat model. Twenty Wistar albino rats were divided into two groups.

Fine-needle aspiration of follicular patterned lesions of the thyroid: diagnosis, management, and follow-up according to thyroid Bethesda system.

Objective: The goal of this study was to report an experience with thyroid fine-needle aspiration (FNA) cases that can be placed into National Cancer Institute-designated thyroid FNA diagnostic categories for follicular patterned lesions divided into three diagnostic categories: follicular lesion of undetermined significance/atypia of undetermined significance (AUS/FLUS), suspicious for follicular neoplasm (SFON), and suspicious for malignancy.

Study Design: The study cohort included 4,284 cases for the period between January 2007 and July 2011 and all available follow-up data was obtained. All cases classified as 'atypical' and 'rule out follicular neoplasm' were included in the AUS/FLUS category (n = 3,903), whereas cases classified as 'suspicious for' or 'consistent with follicular or Hürthle cell neoplasm' (n = 381) were included in the SFON diagnostic category and compared with histopathologic follow-up.

Effects of renin-angiotensin-aldosterone system blockade on chlorhexidine gluconate-induced sclerosing encapsulated peritonitis in rats.

Sclerosing encapsulated peritonitis (SEP) is a rare complication of long term peritoneal dialysis. Renin-angiotensin-aldosterone system (RAAS) may play a role in the development of peritoneal fibrosis in CAPD patients. We aimed to evaluate the effect of aliskiren, valsartan, and aliskiren + valsartan therapy on SEP.
