Action spectra are important biological weighting functions for risk/benefit analyses of ultraviolet (UV) radiation (UVR) exposure. One human benefit exposure to terrestrial solar UVB (∼295 315 nm) is the cutaneous synthesis vitamin D
An earlier study on theoretical identifiability of parameters for a two-step nitrification model showed that unique estimation the yield YA1 is possible with combined respirometric-titrimetric data, contrary to case where only one type measurement available. Here, practical was investigated via evaluation output sensitivity functions and corresponding Fisher Information Matrix (FIM). It appeared FIM not sufficiently powerful predict this measurements as could indeed be identified despite...
Rapid genomic diagnostics in the Neonatal Intensive Care Unit represents a paradigm shift medicine with increasing evidence of utility early diagnosis, impacting management. The goal Utah NeoSeq Project was to implement and evaluate multidisciplinary longitudinal rapid sequencing program while transitioning CLIA-certified sequencing. Enrollment 65 infants resulted 26 (40%) diagnostic variant(s) 7 (11%) harboring strong candidate. This includes re-analyses resulting four additional diagnoses....
Summary Many people take holidays in sunny locations with the express aim of sunbathing. This may result sunburn, which is a risk factor for skin cancer. We investigated 25 D anish sun seekers during week's holiday C anary I slands. The percentage body surface area sunburn was determined by daily examinations same observer. Erythemally effective ultraviolet radiation ( UVR ) exposure assessed time‐stamped personal dosimeters worn on wrist. Volunteers reported their clothing cover and...
Objective: To examine if wound aetiology has an effect on the pain-relieving properties of ibuprofen-releasing foam dressing, which was previously shown to reduce pain in wounds various aetiologies, compared with local best practice (LBP). Method: This a secondary analysis data from multicentre, randomised, parallel group trial patients painful exuding aetiologies. Wound determined at enrolment. Of 853 enrolled into trial, 688 belonged subgroup that included > 25 and were reported here....

Photodynamic therapy (PDT) is followed by significant inflammation. Protoporphyrin (Pp)IX still formed in the skin after PDT and patients are sensitive to daylight 24-48 h treatment. Exposure may therefore increase inflammation.To investigate whether protection with inorganic sunscreen, foundation or light-blocking plaster can reduce inflammation caused daylight-activated PpIX.On right arm of 15 subjects sun-damaged skin, four identical squares (3 × 3 cm) were given conventional Immediately...
The effect of low dose infusions somatostatin on meal stimulated gastric acid secretion was studied in eight healthy volunteers by intragastric titration after a peptone test with radioimmunoassay control the plasma concentrations and pancreatic hormones glucagon insulin. Infusion 100 ng/kg/h, resulting concentration 13.4 +/- 2.1 pmol/l, inhibited significantly, 800 corresponding 66.5 12.0 pmol/l virtually abolished. Plasma insulin decreased significantly during infusion 200 ng/kg/h (24.5...
The main side-effects of photodynamic therapy (PDT) for actinic keratoses (AKs) are post-treatment erythema and oedema, pain during illumination. Severe after PDT enhances the down time associated with treatment.To evaluate in a randomized intraindividual study whether pulse-PDT corticosteroid would reduce treatment-induced compared conventional PDT.Twenty-two patients multiple mild AKs on face scalp were treated methyl aminolaevulinate (MAL)-PDT three similar areas. Two areas incubated MAL...

The effect on gastric acid secretion of blocking transmembrane Ca2+ influx into the parietal cells has been studied in isolated guinea pig fundic mucosa and healthy volunteers. Verapamil inhibited a dose-related manner histamine-stimulated mucosa, whereas stimulation with theophylline dibutyryl cyclic-AMP was unaffected. verapamil (Isoptin®, 2.0 mg/h) stimulated by increasing doses (50,200, 500 ng/kg-h) 15-leucine synthetic human gastrin I seven volunteers, alone combination infusion calcium...
The concentration of gastrin in serum from 47 fasting patients with duodenal ulcer was measured two radioimmunoassays, one specific for the COOH- and other NH2-terminal sequence gastrin-17. COOH-terminal assay 13 ± 2 pmol 42 7 pmol-equivalent gastrin-17 per litre (mean S.E.M.). This result, corroborated by gel chromatography, shows that an fragment gastrin-17, presumably tridecapeptide, circulates concentrations higher than those four known components. abundance suggests complementary...
Activated sludge plants for enhanced biological phosphorus removal (EBPR) are often disturbed by short periods of low organic loading. Depending on the exact nature disturbance this may result in a partial or complete depletion internal PHB stores. and phosphate measurements pilot-scale EBPR process show that recovery from such disturbances is slow temporarily results high concentrations. The strongly suggest main reason dependency P-uptake slowly rising level PHB. In number batch...
The objective of this 6-hour study was to compare rate pain relief, analgesic efficacy and tolerability a novel ibuprofen formulation, sodium dihydrate, with that acid in subjects postoperative dental pain.The test formulation dihydrate (256 mg salt) the reference product both contain 200 ibuprofen. Subjects moderate-to-severe after extraction third molars were randomized receive two tablets either (198 subjects) or double-blind, multicenter trial. Pain measured using traditional descriptor...
The objective of this study was to investigate non-invasive imaging methods update the used regression equation for stationary tested boars. A total 94 boars were examined. 20 dissected provide reference LMP. Performance data (PD) from right carcasses available all groups. left studied by MRI & DXA. Based on LMP and DXA data, equations developed. estimates based calculate new entire male carcass halves linear PD. Further 33 PD sets served as independent sample, which included in a Monte...
