PURPOSE: It is well known that blood perfusion is important for the survival of skin flaps. As no study has been conducted to investigate how the blood perfusion in human eyelid skin flaps is affected by the flap length and diathermy, the present study was carried out to investigate these in patients.METHODS: Fifteen upper eyelids were dissected as part of a blepharoplastic procedure, releasing a

In this paper we prove that the recently introduced method of signal apparition optimally separates signals from interfering sources recorded during simultaneous source seismic data acquisition. By utilizing a periodic sequence of source signatures along one source line, that wavefield becomes separately partially visible in the spectral domain where it can be isolated from interfering signals, pr

Large eyelid full-thickness defects are traditionally repaired using flaps with a blood-supplying pedicle, for the reconstruction of the anterior or posterior lamella or both. This is a 2-stage procedure involving occlusion of vision in the affected eye for 4-8 weeks, as the flap pedicle is not divided until vascularization is deemed adequate. However, the importance of using a flap with a pedicle

The diagnosis of bone metastases is an event with certain consequences for the patient. They often mean pain and can also mean pathological fractures, hypercalcemia, and spinal cord compression, all synonymous with a diminished quality of life and often also hospitalization. Since the advent of the intravenous bisphosphonates, things began to look a bit brighter for patients with bone metastases-b

In the present work, liquid-liquid flow patterns positioned 40 mm downstream the inlet of microchannels were experimentally investigated, including the effect of hydraulic diameter (Dh), liquid properties, aspect ratio of cross section (a) and inlet configuration. Deionized water, butanol, toluene and hexane were selected as probe fluids with water as the continuous phase. Cross-inlet microchannel

Aims and objectives: To explore the barriers for nutritional care as perceived by nursing staff at an acute orthopaedic ward, aiming to implement evidence-based nutritional care. Background: Previous studies indicate that nurses recognise nutritional care as important, but interventions are often lacking. These studies show that a range of barriers influence the attempt to optimise nutritional car

In wavefield signal apparition, acquisition with periodic variations in source activation parameters shifts all or part of a signal cone out to, e.g., the Nyquist wavenumber, enabling perfect separation of simultaneous-source (sim-source) data in a diamond-shaped region below a certain temporal frequency. Cyclic convolution in the spatial frequency domain can be exploited to separate data with kno

The Southern California Borderland is a region that experiences strong natural variations in bottom water oxygen and pH. We use marine sediments from Santa Monica Basin to reconstruct environmental conditions in the basin's bottom water from the Last Glacial Maximum (LGM) to present. We then compare the records to the adjacent Santa Barbara Basin and Santa Lucia Slope. High-resolution records of b

Obesity and cigarette smoking are correlated through complex relationships. Common genetic causes may contribute to these correlations. In this study, we selected 241 loci potentially associated with body mass index (BMI) based on the Genetic Investigation of ANthropometric Traits (GIANT) consortium data and calculated a BMI genetic risk score (BMI-GRS) for 17,037 individuals of European descent f

Knowledge on the occurrence rate of extreme solar storms is strongly limited by the relatively recent advent of satellite monitoring of the Sun. To extend our perspective of solar storms prior to the satellite era and because atmospheric ionization induced by solar energetic particles (SEPs) can lead to the production of odd nitrogen, nitrate spikes in ice cores have been tentatively used to docum

Objective. To explore the prevalence and clinical associations of elevated systolic pulmonary artery pressure (sPAP), measured by Transthoracic Dopplerechocardiography (TTE) in patients with early systemic sclerosis (SSc). Methods. A cross-sectional analysis of the prospective EULAR Scleroderma Trial and Research (EUSTAR) database was performed. SSc patients with < 3 years from the first non-Rayna

Växter behöver ljus för att växa. Ljuset omvandlas till kemisk energi genom fotosyntes i växtens blad. Den kemiska energin kan sedan användas av växten. Ljusabsorptionen i växter har en begränsning. Alltför mycket ljus kommer att orsaka bildning av högenergimolekyler som är skadliga för växterna. Därför måste växter justera mängden ljus som tas upp. Ljuset i miljön förändras ständigt och exponerinLight is essential for plants and algae to process photosynthesis. However, excess of light will cause damage to the organism. A process called non-photochemical quenching (NPQ) is an important way for these organisms to protect themselves from photo oxidative damage. The NPQ process is depend on the xanthophyll cycle in thylakoids, which is controlled by the Violaxanthin de-epoxidase (VDE) and ze
