INTRODUCTION Most of traumatic tympanic membrane perforations have inverted or everted edges, however, the effects of inverted and everted edges on the spontaneous healing of the eardrum remain controversial. OBJECTIVE We investigated the influence of inverted or everted edges on the spontaneous healing of traumatic tympanic membrane perforations. METHODS The clinical records of patients wi...

BACKGROUND AND THE PURPOSE OF THE STUDY Many drug substances along with a variety of naturally occurring dietary or herbal components interact with the CYP enzyme system. The present study was aimed to investigate the effect of pomegranate juice pre-treatment on the transport of carbamazepine across the rat intestine. METHODS The transport of carbamazepine across different parts of rat intest...

For more than 100 years it has been known that the sclerotised median lobe of beetles harbours a membranous structure (the "internal sac" or "endophallus") which is everted during copula inside the female genital tract. In order to explore the functional role of this structure and those associated with it, we cryofixed copulating pairs of Donacia semicuprea and Lilioceris lilii and studied the ...

The Na(+)-glucose cotransporter is a key transport protein that is responsible for absorbing Na(+) and glucose from the luminal contents of the small intestine and reabsorption by the proximal straight tubule of the nephron. Robert K. Crane originally described the cellular model of absorption of Na(+) and glucose by a "cotransport process" in 1960. Over the past 50+ yr, numerous groups have te...

Many drug substances interact with each other and affect the CYP enzyme system and transport properties of other drugs. The present study was aimed to investigate the effect of ketoconazole and rifampicin pre-treatment on the transport of carbamazepine across the intestine in rats. The transport of carbamazepine across different parts of intestine was studied by the everted and non-everted sac ...

Abstract Background Congenital hernia of umbilical cord is a rare congenital anomaly. Due to its presentation as herniation small bowel or other viscera into the cord, it often misdiagnosed omphalocele minor. Case We are reporting case which presented with rupture sac and evisceration loops reverse ileal intussusception via patent vitellointestinal duct. It was managed by first repositioning gu...

Abstract Thin sections of three Palaeozoic bryozoans reveal fossilized soft tissues that show the position organic cuticle and internal structures such as membranous sac gut. The fossilization occurred apparently due to fast burial under anoxic conditions. a in Permian trepostome Rhombotrypella superangustata is indicative progressive polypide cycle.
