Climate warming is shifting the elevational boundary between forests and tundra upwards, but the related belowground responses are poorly understood. In the pristine South and Polar Urals with shifts of the treeline ecotone documented by historical photographs, we investigated fine root dynamics and production of extramatrical mycorrhizal mycelia (EMM) along four elevational transects reaching from the closed forest to the treeless tundra. In addition, we analysed elevational differences in climate and vegetation structure, and excavated trees to estimate related changes in the partitioning between below- and aboveground biomass...

BACKGROUND: Multiple reconstruction techniques have been described in the management of chronic scapholunate (SL) instability, either based on the capsulodesis or tenodesis principle. It is uncertain which surgical method produces the best patient outcomes. We describe results of a technique using palmaris longus (PL) tendon for surgical reconstruction of the SL ligament and provide functional outcomes scores. MATERIALS AND METHODS: We surgically reconstructed the SL ligament using a PL tendon graft secured with Mitek(®) bone anchors...

The smallest flying insects commonly possess wings with long bristles. Little quantitative information is available on the morphology of these bristles, and their functional importance remains a mystery. In this study, we (1) collected morphological data on the bristles of 23 species of Mymaridae by analyzing high-resolution photographs and (2) used the immersed boundary method to determine via numerical simulation whether bristled wings reduced the force required to fling the wings apart while still maintaining lift...

BACKGROUND: Knowledge of the risk factor profile of patients presenting with late-stage age-related macular degeneration (AMD) could help identify the most frequent modifiable AMD precursors among people who are referred for treatment. We aimed to assess dietary behaviours by comparing adjusted mean intakes of micronutrients and major food groups (fruits, vegetables, fish) among patients with AMD and a sample of age-sex-matched controls. METHODS: Cross-sectional analysis of 480 late AMD cases and 518 population-based age-sex-matched controls with no AMD signs...

BACKGROUND: Conifer populations appear disproportionately threatened by global change. Most examples are, however, drawn from the northern hemisphere and long-term rates of population decline are not well documented as historical data are often lacking. We use a large and long-term (1931-2013) repeat photography dataset together with environmental data and fire records to account for the decline of the critically endangered Widdringtonia cedarbergensis. Eighty-seven historical and repeat photo-pairs were analysed to establish 20th century changes in W...

BACKGROUND: Alar retraction is a challenging condition in rhinoplasty marked by exaggerated nostril exposure and awkwardness. Although various methods for correcting alar retraction have been introduced, none is without drawbacks. Herein, we report a simple procedure that is both effective and safe for correcting alar retraction using only conchal cartilage grafting. METHODS: Between August 2007 and August 2009, 18 patients underwent conchal cartilage extension grafting to correct alar retraction...

The federal channel at Port of Miami, Florida, USA, was dredged between late 2013 and early 2015 to widen and deepen the channel. Due to the limited spatial extent of impact-assessment monitoring associated with the project, the extent of the dredging impacts on surrounding coral reefs has not been well quantified. Previously published remote sensing analyses, as well as agency and anecdotal reports suggest the most severe and largest area of sedimentation occurred on a coral reef feature referred to as the Inner Reef, particularly in the sector north of the channel...

BACKGROUND: Most patients treated with orthognathic surgery for facial asymmetry would value improvement in residual soft tissue asymmetry. Autologous fat transfer is widely used to augment facial soft tissue. We assessed the effect of combining orthognathic surgery with autologous fat transfer for treating patients with facial asymmetry. METHODS: In this retrospective study, 15 consecutive adults underwent combined orthognathic surgery and autologous fat transfer between January 2013 and December 2015...

Throughout history, the technological advancements of conventional clinical photography in plastic surgery have refined not only the plastic surgeon's armamentarium, but have invigorated the profession through technology. The technology of the once traditional two-dimensional photograph has since been revolutionized and refashioned to incorporate novel applications, which have since become the standard in clinical photography.Contrary to traditional standardized two-dimensional photographs, three-dimensional photography provides the surgeon with an invaluable volumetric and morphological analysis by demonstrating true surface dimensions both pre and postoperatively...

BACKGROUND: Photographic stimuli are commonly used to assess cue reactivity in the research and treatment of alcohol use disorder. The stimuli used are often non-standardized, not properly validated, and poorly controlled. There are no previously published, validated, American-relevant sets of alcohol images created in a standardized fashion. OBJECTIVES: We aimed to: 1) make available a standardized, matched set of photographic alcohol and non-alcohol beverage stimuli, 2) establish face validity, the extent to which the stimuli are subjectively viewed as what they are purported to be, and 3) establish construct validity, the degree to which a test measures what it claims to be measuring...

Krista A Ehinger, Ruth Rosenholtz
People are good at rapidly extracting the "gist" of a scene at a glance, meaning with a single fixation. It is generally presumed that this performance cannot be mediated by the same encoding that underlies tasks such as visual search, for which researchers have suggested that selective attention may be necessary to bind features from multiple preattentively computed feature maps. This has led to the suggestion that scenes might be special, perhaps utilizing an unlimited capacity channel, perhaps due to brain regions dedicated to this processing...

Importance: Though it has been a common practice to use sharp needles to administer local anesthesia for upper blepharoplasty, the evidence for their benefit is lacking. Objective: To evaluate whether there is any benefit of using blunt-needle injection for local anesthesia when performing upper blepharoplasty to reduce postoperative bruise, hematoma, and pain. Design, Setting, and Participants: Randomized clinical trial of 44 patients who underwent bilateral upper blepharoplasty in an academic medical setting were randomized to receive local anesthesia injections (lidocaine, 2%; 27-gauge needle) with a blunt needle in one eyelid and a sharp needle in the other eyelid...

Importance: Within cosmetic facial plastic surgery, there is considerable difficulty in producing high-quality scientific publications because of the lack of scientific tools that serve to transform sensations, such as more beautiful or rejuvenated, into numbers capable of being used in statistical analysis. Objective: To validate an objective evaluation method that can be used to define the perception of facial age in scientific studies. Design, Setting, and Participants: This is a cross-sectional, observational study of evaluation by plastic surgeons of 70 photographs of patients from a private care hospital performed from March 1, 2015, through April 30, 2016...
