Association of TMAO levels with indicators of ulcerative colitis activity.

Background: The diagnosis of ulcerative colitis (UC) today is limited to a small number of biomarkers. Trimethylamine-N-oxide (TMAO) is the product of reactions resulting from the degradation of dietary-free choline, phosphatidylcholine, and carnitine metabolism by the intestinal microbiota. Earlier studies showed his involvement in the pathogenesis of UC.

Notes on the Taxonomy of (Salicaceae).

L., or golden willow, was described by C. Linnaeus in 1753.

The Ovule Number Variation Provides New Insights into Taxa Delimitation in Willows ( subgen. ; Salicaceae).

, and are closely related species characterized by the lanceolate, acuminate and serrulate leaves. The boundaries between them are defined by relatively few diagnostic characters, and their identification is not fully solved. Recent studies have demonstrated that the number of ovules present in the ovaries of the willow flower can assist in the identification of the species.

Pregnancy outcome following prenatal exposure to triptan medications: a meta-analysis.

Background: Migraine is a common disorder among women of childbearing age. Triptan medications are effective and commonly used to treat migraines in pregnancy. However, the reproductive safety of this group of drugs has not yet been confirmed.

Reduced flow after tubularized incised plate urethroplasty--increased fibrogenesis, elastin fiber loss or neither?

Purpose: Low urinary flow rates are common after tubularized incised plate urethroplasty but the etiology remains unclear and may be related to low urethral compliance due to abnormal collagen concentrations and/or fewer elastic fibers in the healed urethral plate. We hypothesized that inserting a preputial mucosal graft over the dorsal raw area after the midline incision may avoid scarring and improve urethral compliance.

Materials And Methods: Adult rabbits were submitted to tubularized incised plate urethroplasty with or without inlay preputial graft according to a previously described protocol.
