Background: Matrix MetalloProteinases (MMPs) degrade extracellular matrix components to provide normal remodeling and contribute to pathological tissue destruction and cell migration in endometriosis. It is accepted that MMPs are resistant to suppression by progesterone in endometriotic tissues. The physiological effects of progesterone are mediated by its two progesterone receptor (PR) isoform...

Abstract Introduction: One of the contributing factors in ectopic pregnancy is genital infection. The self-treatment of genital infections is a common practice that results in infectious diseases, microbial resistance, and no patient recovery. Objective: This study aimed to determine the relationship between the self-treatment of genital infection and ectopic pregnancy. Materials and Method...

Ectopic thyroid tissue results from abnormal embryologic development and migration of the thyroid gland. True malignant transformation in ectopic thyroid tissue is extremely rare and is always diagnosed after surgical excision of the lesion by pathology examinations. There are well-documented cases of ectopic thyroid cancer while primary tumoral lesion occurs in the orthotopic thyroid, but only...

Introduction: Ectopic teeth occur in a wide variety of sites, including the maxillary sinus, mandibular condyle, coronoid process, orbital, and nasal cavities. Reported symptoms and signs associated with nasal teeth include facial pain, external nasal deformities, foul-smelling rhinorrhea, recurrent epistaxis, and oronasal fistula. Ectopic teeth occurring bilaterally in the nasal cavity is ver...

introduction: ectopic tooth eruption may result owing to one of 3 processes: developmentaldisturbance, iatrogenic activity, or pathologic process, such as a tumor or a cyst. in rare cases, occlusion of the sinus ostia may predispose a patient to develop a maxillary sinus mucocele. when the maxillary sinus is invaded, symptoms usually occur late in the process.   case report: a 17 years old boy ...

ectopic decidualization with gross involvement of the peritoneum is one of the rare findings in pregnant women particularly when ectopic decidualization disseminated as an asymptomatic intra-abdominal nodule. we present here a case of an ectopic decidualization in a 33-year-old pregnant woman with symptoms of irritable bowel syndrome during pregnancy.

The ability of parental to F(1) spleen grafts to regenerate was equal to that of parental to parental or to F(1) or F(1) spleen grafts. Cytotoxicity analysis of parental to F(1) spleen and thymic grafts indicated that these "regenerated grafts" were composed of F(1) lymphocytes. Regenerated parental to F(1) spleen grafts were incapable of producing runt disease in newborn F(1) animals.
