Using a Bull Call Spread
4 pp., 1 figure, 3 tablesThe Bull Call Spread can be used to hedge against or to benefit from a rising market. The user buys a call option at a particular strike price and sells a call option at a higher strike price. Margin requirements, advantages and disadvantages of this strategy are explained
The Economic Impact of Intensive Commodity Price Risk Management Education
Research shows that risk management, and in particular price risk management, has been a major concern for agricultural producers, and as such, has been the target area of a substantial amount of Extension education programming. Analysis of survey results indicate that the Master Marketer program, a 64-hour intensive training program that develops master volunteers who extend the education through marketing clubs, is a valuable Extension program helping producers to better-manage price and production risks. On average, graduates of the program have increased their net income by more than $33,000 annually

Pb(II) Induces Scramblase Activation and Ceramide-Domain Generation in Red Blood Cells
The mechanisms of Pb(II) toxicity have been studied in human red blood cells using confocal microscopy, immunolabeling, fluorescence-activated cell sorting and atomic force microscopy. The process follows a sequence of events, starting with calcium entry, followed by potassium release, morphological change, generation of ceramide, lipid flip-flop and finally cell lysis. Clotrimazole blocks potassium channels and the whole process is inhibited. Immunolabeling reveals the generation of ceramide-enriched domains linked to a cell morphological change, while the use of a neutral sphingomyelinase inhibitor greatly delays the process after the morphological change, and lipid flip-flop is significantly reduced. These facts point to three major checkpoints in the process: first the upstream exchange of calcium and potassium, then ceramide domain formation, and finally the downstream scramblase activation necessary for cell lysis. In addition, partial non-cytotoxic cholesterol depletion of red blood cells accelerates the process as the morphological change occurs faster. Cholesterol could have a role in modulating the properties of the ceramide-enriched domains. This work is relevant in the context of cell death, heavy metal toxicity and sphingolipid signaling.AGA was a predoctoral student supported by the Basque Government and later by the University of the Basque Country (UPV/EHU).

Trial of Optimal Personalised Care After Treatment for Gynaecological cancer (TOPCAT-G): a study protocol for a randomised feasibility trial
Background: Gynaecological cancers are diagnosed in over 1000 women in Wales every year. We estimate that this is
costing the National Health Service (NHS) in excess of ÂŁ1 million per annum for routine follow-up appointments alone.
Follow-up care is not evidence-based, and there are no definitive guidelines from The National Institute for Health and
Care Excellence (NICE) for the type of follow-up that should be delivered. Standard care is to provide a regular medical
review of the patient in a hospital-based outpatient clinic for a minimum of 5 years. This study is to evaluate the
feasibility of a proposed alternative where the patients are delivered a specialist nurse-led telephone intervention
known as Optimal Personalised Care After Treatment for Gynaecological cancer (OPCAT-G), which comprised of a
protocol-based patient education, patient empowerment and structured needs assessment.
Methods: The study will recruit female patients who have completed treatment for cervical, endometrial,
epithelial ovarian or vulval cancer within the previous 3 months in Betsi Cadwaladr University Health Board
(BCUHB) in North Wales. Following recruitment, participants will be randomised to one of two arms in the trial
(standard care or OPCAT-G intervention). The primary outcomes for the trial are patient recruitment and attrition
rates, and the secondary outcomes are quality of life, health status and capability, using the EORTC QLQ-C30, EQ-
5D-3L and ICECAP-A measures. Additionally, a client service receipt inventory (CSRI) will be collected in order to
pilot an economic evaluation.
Discussion: The results from this feasibility study will be used to inform a fully powered randomised controlled
trial to evaluate the difference between standard care and the OPCAT-G intervention.

Contribution of trans regulatory eQTL to cryptic genetic variation in C-elegans
BackgroundCryptic genetic variation (CGV) is the hidden genetic variation that can be unlocked by perturbing normal conditions. CGV can drive the emergence of novel complex phenotypes through changes in gene expression. Although our theoretical understanding of CGV has thoroughly increased over the past decade, insight into polymorphic gene expression regulation underlying CGV is scarce. Here we investigated the transcriptional architecture of CGV in response to rapid temperature changes in the nematode Caenorhabditis elegans. We analyzed regulatory variation in gene expression (and mapped eQTL) across the course of a heat stress and recovery response in a recombinant inbred population.ResultsWe measured gene expression over three temperature treatments: i) control, ii) heat stress, and iii) recovery from heat stress. Compared to control, exposure to heat stress affected the transcription of 3305 genes, whereas 942 were affected in recovering animals. These affected genes were mainly involved in metabolism and reproduction. The gene expression pattern in recovering animals resembled both the control and the heat-stress treatment. We mapped eQTL using the genetic variation of the recombinant inbred population and detected 2626 genes with an eQTL in the heat-stress treatment, 1797 in the control, and 1880 in the recovery. The cis-eQTL were highly shared across treatments. A considerable fraction of the trans-eQTL (40–57%) mapped to 19 treatment specific trans-bands. In contrast to cis-eQTL, trans-eQTL were highly environment specific and thus cryptic. Approximately 67% of the trans-eQTL were only induced in a single treatment, with heat-stress showing the most unique trans-eQTL.ConclusionsThese results illustrate the highly dynamic pattern of CGV across three different environmental conditions that can be evoked by a stress response over a relatively short time-span (2 h) and that CGV is mainly determined by response related trans regulatory eQTL.<br/
