Updating, correcting, and calibrating the narrative about premature ejaculation.

Introduction: The narrative surrounding premature ejaculation (PE) has developed and solidified over the past 25 years. Unfortunately, portions of that narrative are outdated and do not reflect more recent conceptualizations or empirical findings regarding this disorder.

Objective: In this review we sought to identify existing narratives about PE in need of updating and to provide revised narratives based on the recent research literature.

A genetically encoded sensor for visualizing leukotriene B4 gradients in vivo.

Leukotriene B (LTB) is a potent lipid chemoattractant driving inflammatory responses during host defense, allergy, autoimmune and metabolic diseases. Gradients of LTB orchestrate leukocyte recruitment and swarming to sites of tissue damage and infection. How LTB gradients form and spread in live tissues to regulate these processes remains largely elusive due to the lack of suitable tools for monitoring LTB levels in vivo.

Why Men Masturbate: Reasons and Correlates in Men with and without Sexual Dysfunction.

Men purportedly masturbate for a variety of reasons, but systematic investigation of men's reasons has been lacking. We analyzed reasons why men masturbate ( = 2967, mean age = 37.7, SD = 12.

Microarchitecture of the Augmented Bone Following Sinus Elevation with an Albumin Impregnated Demineralized Freeze-Dried Bone Allograft (BoneAlbumin) versus Anorganic Bovine Bone Mineral: A Randomized Prospective Clinical, Histomorphometric, and Micro-Computed Tomography Study.

Serum albumin has been identified as an endogenous protein that is integral to early bone regeneration. We hypothesized that albumin addition to allografts may result in better bone remodeling than what can be achieved with anorganic xenografts. Sinus elevations were performed at 32 sites of 18 patients with the lateral window technique.
