Species of Phragmoceras in the Silurian of Gotland and Britain are reviewed and revised. One new species P. exaggeratus is described from the Ludlow Series of the Welsh Borderland. There are comments on the broader distribution of the genus and on its mode of life.
A blend of rapeseed and butter oil was transesterified using immobilized Thermomyces lanuginosus lipase (Lipozyme (R) TL IM) as catalyst. The reaction was followed by reversed-phase HPLC and the triacylglycerol peaks were tentatively identified from their elution times by calculating equivalent carbon numbers. Further identification was made using HPLC-electrospray tandem mass spectrometry. A few
Trypsinogen is a serine proteinase produced mainly by the pancreas, but it has recently been found to be expressed also in several cancers such as ovarian and colon cancer and in vascular endothelial cells. In this study, we found that trypsinogen-1 and -2 are present at high concentrations (median levels, 0.4 and 0.5 mg/L, respectively) in human seminal fluid and purified them to homogeneity by i
BACKGROUND: The Case Method (Case) and Problem Based Learning (PBL) are two student active methods, increasingly used in medical education. AIM: The aim of this study was to compare medical student satisfaction with the two different active methods of learning and to see if there was any variation in preference between two stages in medical training. METHODS: A short questionnaire was given out to
The aim of this study was to illuminate the pattern of confusional episodes with regard to the content of elderly patients' actions and speech. Fifty-one (11.2%) out of 457 people admitted to an orthopaedic clinic developed acute confusional state. Non-participant direct observations and daily clinical bedside follow-up observations were made during the confusional episodes, focusing on the patien
Objective. To examine, in an inception cohort of systemic lupus erythematosus (SLE) patients, the association between neuropsychiatric (NP) events and anti-ribosomal P (anti-P), antiphospholipid (lupus anticoagulant [LAC], anticardiolipin), anti-beta 2-glycoprotein I, and anti-NR2 glutamate receptor antibodies. Methods. NP events were identified using the American College of Rheumatology case defi
The FUS gene at 16p11 fuses with DDIT3 and ATF1 as the result of translocations with chromosome band 12q13 in myxoid liposarcoma and angiomatoid fibrous histiocytoma, respectively, and with ERG as the result of a t(16;21)(p11;q22) in acute myeloid leukemia. We here show that a t(7;16)(q33;p11) in two cases of low grade fibromyxoid sarcoma fuses the FUS gene to BBF2H7, a previously uncharacterized
In cooperative, breeding vertebrates, indirect fitness benefits would be maximized by subordinates that accurately assess their relatedness to group offspring and preferentially help more closely related kin. In the Seychelles warbler (Acrocephalus sechellensis), we found a positive relationship between subordinate-nestling kinship (determined using microsatellite marker genotypes) and provisionin
Recent evidence suggests that many Australian agamids show temperature-dependent sex determination (TSD) with variation in sex determining mechanisms among closely related taxa. However, as shown in other vertebrates, sex ratios can also be influenced by genetic or phenotypic differences among females in their propensity to produce sons or daughters, and these influences might confound any thermal
The Leon-Chinandega plains are located in the north-western part of Nicaragua and represent the most important groundwater reservoir of the country. The aquifer is comprised of three hydrogeological units. The top unit is an unconfined alluvial and below a more consolidated volcanic aquifer is found. These aquifers rest on an ignimbrite unit that acts as the basement of the aquifer. The plains are
This review paper focuses on modelling of wastewater treatment plants (WWTP). White-box modelling is widely applied in this field, with learning, design and process optimisation as the main applications. The introduction of the ASM model family by the IWA task group was of great importance, providing researchers and practitioners with a standardised set of basis models. This paper introduces the n
To use nutrition in order to limit the negative consequences of physical and mental stress is not new. Recent advances in immunology and particularly in the understanding of the chemical language used to communicate both by eukarytic and prokarotic cells has made it easier to objectively evaluate effects of various immunomodulating efforts including the use of nutrients, vitamins and antioxidants
Wrap-gate (111) InAs nanowires (NWs) were studied after HfO2 dielectric coating and Cr metallic deposition by a combination of grazing incidence x-ray techniques. In-plane and out-of-plane x-ray diffraction (crystal truncation rod analysis) allow determining the strain tensor. The longitudinal contraction, increasing with HfO2 and Cr deposition, is significantly larger than the radial dilatation.
