Although many studies have demonstrated the physiological action of motilin on the migrating motor complex, the precise mechanisms remain obscure. To obtain new insights into the mechanisms, we focused on the house musk shrew (Suncus murinus, suncus used as a laboratory name) as a small model animal for in vivo motilin study, and we studied the physiological characteristics of suncus gastrointe...

Spermatozoa mediated gene transfer has become a promising technology to generate transgenic animals with disease resistance. However, exogenous DNA invasion may cause changes in spermatozoon natural defense system which result in spermatozoon dysfunction.The objective of this study was to investigate the changes of mitochondrial function and motility in goat spermatozoa after pre-incubation and...

BACKGROUND The 5-HT1 agonist sumatriptan, used in the treatment of migraine, can cause chest pain. AIM To investigate the effect of a therapeutic dose of sumatriptan (6 mg s.c.) on oesophageal motility. METHODS In 16 normal healthy subjects aged 19-32 years (9 males), the manometric response of the lower oesophageal sphincter (sleeve sensor), oesophageal body (four sites), stomach and phary...

BACKGROUNDS AND AIMS This study aimed to compare the esophageal motility between gastroesophageal reflux disease (GERD) patients with typical symptoms but without globus sensation and GERD patients only with globus symptoms. METHODS A total of 57 consecutive GERD patients diagnosed by endoscopy or by 24-hour pH monitoring between May 2013 and September 2015 were included retrospectively into ...

The aim of this study is to evaluate the benefits of laparoscopic Doppler ultrasound (LDU) application during laparoscopic varicocelectomy (LV), and to compare the surgical outcomes and complications between LDU-assisted LV (LDU-LV) and conventional LV for infertile patients with varicoceles; 147 infertile patients were randomly divided into two groups. Operative and postoperative parameters, s...

BACKGROUND The aim of this study was to investigate whether any esophageal motor dysfunction exists in patients with iron deficiency anemia (IDA). METHODS The study included 39 patients (34 women, mean age: 44.17 ± 14.21 years) who met WHO diagnostic criteria for IDA. An additional 30 functional dyspepsia patients were also included as a control group. Esophageal motility testing was performe...

Sperm cryopreservation is a valuable tool for the genetic management of ex situ populations. This study was conducted to assess: (1) semen characteristics of wild-born cheetahs; and (2) the impact of three types of glycerol influence (duration of exposure, temperature, and method of addition) on sperm cryosensitivity. To evaluate the impact of duration of glycerol exposure, spermatozoa were inc...

Objective(s):This study was carried out to investigate the effects of COX-2 selective inhibitor (Celecoxib) or non-selective COX inhibitor (Ibuprofen) on gastrointestinal motility. Materials and Methods: The rats were randomly divided into five groups including: intact, sham, traumatic brain injury (TBI) group (intact rats under TBI), Celecoxib group (10 mg/kg), Ibuprofen group (10 mg/kg). Rats...

Using a newly developed gradient chamber to provide independent measurements of chemokinesis (stimulated motility) and chemotaxis (stimulated motility up a concentration gradient) of individual T-helper cells, it was recently demonstrated that HIV-induced T-cell syncytia release two distinct chemotactic activities that are separable by their rates of diffusion. The molecular masses of the two c...

Background: Iron deficiency, is a common worldwide complication, especially in preschool children. Iron deficiency anemia (IDA) is associated with changes in the mental and motor development, defects of immune system, cardiovascular, diseases and disruption of lipid profile. In IDA, the occurrence of dyslipidemia is controversial. We aimed to investigate the association between IDA and serum li...
