Abdominal pregnancy implanted on surface of pedunculated subserosal uterine leiomyoma: A case report.

Abdominal pregnancy is a rare form of ectopic pregnancy. Various sites of implantation in abdominal pregnancy have been reported. Uterine serosa is an extremely rare implantation site, with only a few cases reported to date.

Ovarian abscess caused by in a patient with endometriosis.

is a rarely encountered pathogen that easily induces bacteremia. Various foci of infection have been reported; however, no case of adnexal abscess caused by has been reported in the English literature. We herein report a case of ovarian abscess caused by .

Synthesis of Chiral TFA-Protected α-Amino Aryl-Ketone Derivatives with Friedel-Crafts Acylation of α-Amino Acid N-Hydroxysuccinimide Ester.

Chiral -protected α-amino aryl-ketones are one of the useful precursors used in the synthesis of various biologically active compounds and can be constructed via Friedel-Crafts acylation of -protected α-amino acids. One of the drawbacks of this reaction is the utilization of toxic, corrosive and moisture-sensitive acylating reagents. In peptide construction via amide bond formation, -hydroxysuccinimide ester (OSu), which has high storage stability, can react rapidly with amino components and produces fewer side reactions, including racemization.

Mast cell hyperactivity underpins the development of oxygen-induced retinopathy.

Mast cells are classically thought to play an important role in protection against helminth infections and in the induction of allergic diseases; however, recent studies indicate that these cells also contribute to neovascularization, which is critical for tissue remodeling, chronic inflammation, and carcinogenesis. Here, we demonstrate that mast cells are essential for sprouting angiogenesis in a murine model of oxygen-induced retinopathy (OIR). Although mouse strains lacking mast cells did not exhibit retinal neovascularization following hypoxia, these mice developed OIR following infusion of mast cells or after injection of mast cell tryptase (MCT).

Resolution of dopamine agonist-resistant hyperprolactinemia by hysterectomy: a case report.

Prolactin-producing uterine leiomyomas are very rare. Although hyperprolactinemia rapidly improves after removal of such leiomyomas, no preoperative diagnostic test has been established for prolactin-producing uterine leiomyomas. A 45-year-old Japanese woman, gravida 3 para 3, was referred to our hospital for further examination of hyperprolactinemia resistant to a dopamine agonist.
