Stapes and Stapes Revision Surgery: Preoperative Air-Bone Gap Is a Prognostic Marker.

Objective: Stapes surgery is considered an effective treatment in otosclerosis, but controversy remains regarding predictors of surgical outcome.

Study Design: Retrospective cohort study.

Setting: Tertiary referral center.

Nutrient quality of vertebrate dung as a diet for dung beetles.

At the basis of a trophic web, coprophagous animals like dung beetles (Scarabaeoidea) utilize resources that may have advantages (easy gain and handling) as well as drawbacks (formerly processed food). Several studies have characterized the nutrients, e.g.

Carbohydrate intake and training efficacy - a randomized cross-over study.

Carbohydrate (CHO) availability during endurance exercise seems to attenuate exercise-induced perturbations of cellular homeostasis and might consequently diminish the stimulus for training adaptation. Therefore, a negative effect of CHO intake on endurance training efficacy seems plausible. This study aimed to test the influence of carbohydrate intake on the efficacy of an endurance training program on previously untrained healthy adults.

Tree Species Composition and Harvest Intensity Affect Herbivore Density and Leaf Damage on Beech, Fagus sylvatica, in Different Landscape Contexts.

Most forests are exposed to anthropogenic management activities that affect tree species composition and natural ecosystem processes. Changes in ecosystem processes such as herbivory depend on management intensity, and on regional environmental conditions and species pools. Whereas influences of specific forest management measures have already been addressed for different herbivore taxa on a local scale, studies considering effects of different aspects of forest management across different regions are rare.

A new nanosecond UV laser at 355 nm: early results of corneal flap cutting in a rabbit model.

Purpose: A new 355 nm UV laser was used for corneal flap cutting in an animal model and tested for clinical and morphologic alterations.

Methods: Corneal flaps were created (Chinchilla Bastards; n = 25) with an UV nanosecond laser at 355 nm (150 kHz, pulse duration 850 ps, spot-size 1 μm, spot spacing 6 × 6 μm, side cut Δz 1 μm; cutting depth 130 μm) and pulse energies of 2.2 or 2.
