Context • Pain from osteoarthritis is associated with peripheral nociception and central pain processing. Given the unmet need for innovative, effective, and well-tolerated therapies, many patients, after looking for more satisfactory alternatives, decide to use complementary and alternative modalities. The analgesic mechanism of subcutaneous injections of diluted bee venom into an acupoint is thought to be part of an anti-inflammatory effect and the central modulation of pain processing. Objectives • Using the rat model of collagenase-induced osteoarthritis (CIOA), the study intended to investigate the analgesic effects of bee venom acupuncture (BVA) as they are related to the acupuncture points and dosage used and to determine whether the analgesic mechanisms of BVA for pain were mediated by opioid or adrenergic receptors...

Soil heavy metal contents were measured in newly submerged areas of the Danjiangkou Reservoir, China. We aimed to determine the heavy metal distribution in this area and the associated ecological risk. Most of these heavy metal contents (except Pb and Mn) suggest enrichment compared with the background values of soils from Henan Province, especially As and Cd with mean geo-accumulation index (Igeo) values of 0.84 and 0.54. The spatial analysis results indicated that the highest heavy metal contents were distributed in the arable soils above 160m elevation, whereas low heavy metal contents were observed under other land-use types above 160m elevation...

In an effort to explore the residual complexity of naturally occurring chalcones from the roots of Glycyrrhiza inflata (Fabaceae), two new licochalcone A (LicA) derivatives were isolated as trace metabolites from enriched fractions. Both constituents contain a dihydrofuran moiety linked to carbons C-4 and C-5 of the retrochalcone core. Compound 1 (LicAF1) represents a new chemical entity, whereas compound 2 (LicAF2) has previously been reported as a Lewis acid catalyzed rearrangement of LicA. Evaluation of chirality revealed that both dihydrofuran derivatives existed as a mixture of R and S enantiomers...

Ultrafiltration (UF) is largely used in the dairy industry to generate milk and whey protein concentrate for standardization of milk or production of dairy ingredients. Recently, it was demonstrated that high hydrostatic pressure (HHP) extended the shelf life of milk and improved rennet coagulation and cheese yield. Pressurization also modified casein micelle size distribution and promoted aggregation of whey proteins. These changes are likely to affect UF performance. Consequently, this study will determine the effect of skim milk pressurization (300 and 600 MPa, 5 min) on UF performance in terms of permeate flux decline and fouling...

In this study, the particle size-resolved distribution from a China-3 certificated light-duty diesel vehicle was measured by using a portable emission measurement system (PEMS). In order to examine the influences of vehicle specific power (VSP) and high-altitude operation, measurements were conducted at 8 constant speeds, which ranged from 10 to 80km/hr at 10km/hr intervals, and two different high altitudes, namely 2200 and 3200m. The results demonstrated that the numbers of particles in all size ranges decreased significantly as VSP increased when the test vehicle was running at lower speeds (<20km/hr), while at a moderate speed (between 30 and 60km/hr), the particle number was statistically insensitive to increase VSP...

PURPOSE: We set out to evaluate how residents in pediatric surgery learn and how they teach. We hypnotized that European residents learn as much from their peers and teach as much as their fellows worldwide, but that they receive comparably less educational training. METHODS: An online questionnaire was distributed to the participants of the combined annual meeting for German, Swiss and Austrian residents in pediatric surgery. Participants were asked whom they learn from in different workplace environments (ward, operating room, emergency department), how, when and why they adopt the role of teacher and how they were prepared for this role...
