Investigation of growth curves with different nonlinear models and MARS algorithm in broiler chickens.

This study was conducted to determine the live weight model of the broiler chicks by using the most appropriate mathematical growth curves. Live weights were used in broiler chicks grown for 0-6 weeks. Logistics, Gompertz, Weibull, Hossfeld and Von Bertalanffy models and multivariate adaptive regression splines (MARS) data mining algorithm were used to define the live weights of the chickens.

Evaluation of mucosal status in the follow-up of pediatric patients with celiac disease: the role of serology.

Unlabelled: Recent guidelines suggest non-biopsy serology-based approach for the diagnosis of celiac disease; however, there is no evidence-based data regarding noninvasive follow-up of mucosal healing. The aim of this study is to investigate the efficacy of serology in reflecting mucosal status in the follow-up of pediatric patients with celiac disease. This is a validation study conducted at a university hospital.

Electrode effects on the observability of destructive quantum interference in single-molecule junctions.

Destructive quantum interference (QI) has been a source of interest as a new paradigm for molecular electronics as the electronic conductance is widely dependent on the occurrence or absence of destructive QI effects. In order to interpret experimentally observed transmission features, it is necessary to understand the effects of all components of the junction on electron transport. We perform non-equilibrium Green's function calculations within the framework of density functional theory to assess the structure-function relationship of transport through pyrene molecular junctions with distinct QI properties.

Low Titer Tissue Transglutaminase Antibodies: A Link to Helicobacter pylori Infection?

Introduction: Low serum titer of anti-tissue transglutaminase (tTG) has been described in various conditions without any evidence of celiac disease (CD). Infectious agents have been suggested to trigger autoimmunity and promote the production of anti-tTG. The aim of this study was to investigate if there is a link between a positive celiac serology and concomitant Helicobacter pylori infection in children.

Gastrointestinal sarcoidosis presenting with malabsorption at an early age.

Sarcoidosis is a chronic multisystemic granulomatous disease that predominantly involves the thoracic lymph nodes and lungs and primarily occurs in young adults. Isolated extrapulmonary localization is uncommon in adults, and exceptionally rare in the pediatric age group. A 4-year-old male patient with chronic diarrhea and abdominal distention for the last 8 months is presented.

A Rare Complication of Giardiasis in Children: Protein-losing Enteropathy.

Protein-losing enteropathy may develop as a complication of a wide spectrum of diseases. Three cases of giardiasis that presented with acute onset of hypoalbuminemia were documented, and resolution of protein loss after treatment was also confirmed. Thus, chronic enteric infections should be considered as an etiology of severe intestinal protein loss, particularly in children.

Evaluation of pain during hysterosalpingography with the use of balloon catheter vs metal cannula.

Our aim was to investigate the use of a balloon catheter device in comparison with metal cannula for hysterosalpingography (HSG) in terms of patient comfort. A total of 168 patients were randomised for HSG either with a balloon catheter (n = 83) or metal cannula (n = 85). Scores of pelvic pain during insertion of the devices, injection of the contrast medium and 1 h after the procedure were evaluated using the Wong Baker Faces Pain Rating Scale; complications and reinsertion rates were also noted.

Background: The association between blood types and ovarian reserve is investigated in this study.

Materials And Methods: As an index of ovarian reserve, women with a follicle stimulat- ing hormone (FSH) level of ≥10 mIU/ml in the early follicular phase were designated as having diminished ovarian reserve. In this prospective study, early follicular phase serum FSH and estradiol levels and blood types were evaluated in 500 patients who were admitted to the Infertility Department of Ministry of Health Etlik Zübeyde Hanım Women's Health Training and Research Hospital between January 2012 and June 2012.

Clomiphene citrate 'stair-step' protocol vs. traditional protocol in patients with polycystic ovary syndrome: a randomized controlled trial.

Purpose: To evaluate the efficacy of the stair-step protocol using clomiphene citrate (CC) and to assess the uterine and systemic side effects in patients with polycystic ovary syndrome (PCOS).

Methods: A total of 60 PCOS patients who failed to respond to 50 mg/day for 5 days of CC treatment within the cycle were randomly allocated to the control (traditional protocol) and study (stair-step protocol) groups. In the stair-step protocol,patients were treated with CC 50 mg/day for 5 days and then in nonresponsive patients, the dosage was increased to 100 mg/day for 5 days in the same cycle.

Concomitant imperforate hymen and transverse vaginal septum complicated with pyocolpos and abdominovaginal fistula.

A 13-year-old patient with a complaint of worsening lower abdominal pain during the past 4 months was admitted to the emergency department. An abdominopelvic ultrasound scan revealed a distended uterocervical cavity suggestive of hematometrocolpos. Imperforate hymen was observed on examination of the external genitalia.

High serum HTATIP2/TIP30 level in serous ovarian cancer as prognostic or diagnostic marker.

Background: Human HIV-1 TAT interactive protein 2 (HTATIP2/TIP30) is an evolutionarily conserved gene that is expressed ubiquitously in human tissues and some tumor tissues. This protein has been found to be associated with some gynecological cancers; as such, this study aimed to investigate blood HTATIP2/TIP30 levels in patients with ovarian cancer.

Methods: Twenty-three women with ovarian cancer and 18 patients with various non-cancerous gynecological complaints (for example, dysfunctional uterine bleeding, fibroids, and urinary incontinence) were included in the study.

Bilateral ovariectomy in young rats: what happens in their livers during cecal ligation and puncture induced sepsis?

Study Objective: Pediatric ovarian masses comprise a heterogeneous group of benign and malignant lesions. Surgical methods consist of emergency or programmed surgery with tumoral resection and uni/bilateral oophorectomy or salpingo-oophorectomy. We examined whether bilateral ovariectomy (OVX) worsens liver injury during the onset of cecal ligation and puncture (CLP)-induced sepsis in rats.

Background: To evaluate biochemically and histopathologically the effects of Nigella sativa (NS) in experimental ischemia and ischemia/reperfusion (I/R) injury in rat ovaries.

Methods: Thirty-six female rats were divided into 6 groups: group I = sham operation; group II = 500 mg/kg NS + sham operation; group III = bilateral ovarian ischemia; group IV = 500 mg/kg NS + ischemia; group V = 3-hour period of ischemia + 3-hour reperfusion, and group VI: 3-hour period of ischemia + 500 mg/kg NS 2.5 h after the induction of ischemia + 3-hour reperfusion.

Effects of diabetes mellitus on the rat liver during the postmenopausal period.

The present study investigated whether diabetes worsened the onset of liver injury/damage during the ovariectomized (OVX)-induced postmenopausal period in rats. Diabetes results in severe complications in humans, such as liver failure. Estrogen and its derivatives are medically acceptable, powerful antioxidant agents that can enable liver and other important organs to defend themselves against oxidative related injury.
