The immense increase in metaphor theory and research over the past decades is posing a threat of fragmentation to the field, which has been responded to by calls for new and more encompassing approaches to virtually all aspects metaphorical. This article argues that the opposite response may be more productive. By focusing on a different way of theorizing metaphor and its comprehension, existing theories and data can be re-ordered in an alternative and coherent way, which moreover breaks new grounds in tying up both with a general theory for all utterance comprehension as well as a general theory for all cognition as involving fast and slow thinking.

The GnRH-agonists are the only clinically available drugs in this indication, but their use and mechanisms of protection are still controversial. Recently, we have investigated new targeted drugs based on microRNA (miRNA) replacement therapy, and have identified the let-7a miRNA as candidate for fertility preservation strategies.

We report a clinical case series, illustrating the dilemma in deciding the best treatment should denosumab be stopped.

Anticancer treatments may have an additional negative impact on the ovarian reserve and subsequently on the fertility of young patients carrying such mutations. Recently, the combination of carboplatin and paclitaxel is being recommended to these BRCA-mutated patients as neoadjuvant therapy.

To date, the impact of Let-COH on the follicular microenvironment has been poorly investigated, although a high androgen/estrogen ratio was previously associated with low oocyte quality.
Methods: In this prospective study, follicular fluid (FF) steroid levels (estradiol, testosterone, progesterone) and cumulus cell (CC) gene expression related to oocyte quality (HAS2, PTGS2, GREM1) were compared between 23 BC patients undergoing Let-COH for FP and 24 infertile patients undergoing conventional COH without letrozole.
This work is focused on the role of temperature in the de-mixing of absorbance spectra measured in mixed aqueous NaSO and NaNO solutions. First, the influence of temperature on the absorbance spectrum of demineralized water was determined. Second, the absorbance spectra of five separate electrolytes (NaNO, NaNO, CaCl, KCO, and NaOH) at three temperatures (4°C, 25°C, and 50°C) for concentrations ranging from 0.

The aim of this study is to identify whether bone turnover markers, relevant biochemical parameters or total body fat and muscle composition affect the response to rPTH and to establish if these parameters in particular change during treatment.

Still, we know little about how such concepts are formed, processed, and represented in mind. For example, because abstract concepts do not designate referents that can be experienced through our body, the role of perceptual experiences in shaping their content remains controversial.

Summary Answer: The absence of FSH in vivo and the direct exposition of ovarian follicles to GnRH analogues in vitro did not prevent chemotherapy-induced ovarian damage.
What Is Known Already: The potential mechanisms of action of GnRH analogues in protecting ovaries against chemotherapy damage remain poorly understood. We previously showed that GnRH analogues have a limited inhibitory effect on gonadotropin secretion and follicular growth in mice.
This article considers co-creation as a new persuasive strategy in health campaigns. Co-creation enables target audience members to become active campaign producers. A recent Dutch anti-smoking campaign applied co-creation, inviting the target audience to complete the slogan "smoking is sóóó .

Diffusion tensor imaging (DTI) has shown promise in TBI, but much less is known about aSAH.
Objective: To explore the use of whole-brain DTI tractography in TBI and aSAH as a biomarker and early endpoint.
As many chemotherapy regimens induce follicular depletion, fertility preservation became a major concern in young cancer patients. By maintaining follicles at the resting stage, gonadotropin-releasing hormone analogues (GnRHa) were proposed as an ovarian-protective option during chemotherapy. However, their efficacy and mechanisms of action remain to be elucidated.

The effects of 16 dissolved salts were investigated in the wavelength range from 14000 to 9091 wavenumbers (714-1100 nm) by linear fits of the differential absorbance values (Y(υ,c)=offset(υ)+b(υ)×c) recorded for each wavenumber (υ) and concentration (c) ranges from 500 to 30 mM. The slopes (b) of these fits resulted in clear fingerprints of the electrolytes.

Design: Expression of breast markers was evaluated by quantitative polymerase chain reaction in ovarian tissue from patients with benign or cancerous diseases. Suspected tissues were long-term xenografted into mice.
In this article, we offer a critical view of Thibodeau and Boroditsky who report an effect of metaphorical framing on readers' preference for political measures after exposure to a short text on the increase of crime in a fictitious town: when crime was metaphorically presented as a beast, readers became more enforcement-oriented than when crime was metaphorically framed as a virus. We argue that the design of the study has left room for alternative explanations. We report four experiments comprising a follow-up study, remedying several shortcomings in the original design while collecting more encompassing sets of data.

Here, we investigate how SOX9 operates in pancreatic tumourigenesis.
Design: We analysed genomic and transcriptomic data from surgically resected PDAC and extended the expression analysis to xenografts from PDAC samples and to PDAC cell lines.
Background: The growing number of web-based psychological treatments, based on textual communication, generates a wealth of data that can contribute to knowledge of online and face-to-face treatments. We investigated whether clients' language use predicted treatment outcomes and adherence in Master Your Mood (MYM), an online group course for young adults with depressive symptoms.
Methods: Among 234 participants from a randomised controlled trial of MYM, we tested whether their word use on course application forms predicted baseline levels of depression, anxiety and mastery, or subsequent treatment adherence.
Background: Presence of the 3-epi-25-hydroxyvitamin D3 [3-epi-25(OH)D3] metabolite affects accurate determination of 25(OH)D3 by most routine liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods and to an unknown extent in present immuno- and protein binding assays. We studied 3-epi-25(OH)D3 cross-reactivity in a competitive protein binding (CPB) assay (Roche Elecsys).
Methods: Neonatal samples, containing up to 58% of 3-epi-25(OH)D3 were used for measurement by the CPB assay and by an LC-MS/MS method separating 25(OH)D3 and 3-epi-25(OH)D3.
In this work we report on the ultrafast photodynamics of the photosensitizer zinc phthalocyanine (ZnPc) and manipulation thereof. Two approaches are followed: active control via pulse shaping and passive control via strategic manipulation in the periphery of the molecular structure. The objective of both of these control experiments is the same: to enhance the yield of the functional pathway and to minimize loss channels.

Histologically, the onset of this switch is characterised by the co-expression of acinar and ductal markers in acini, a lesion called acinar-to-ductal metaplasia (ADM). The transcriptional regulators required to initiate ADM are unknown, but need to be identified to characterise the regulatory networks that drive ADM.

Methods: We assessed the prevalence of HBP in women at the time of the first pregnancy visit using both a prospective cohort (N = 703) and a retrospective series of women selected at random (N = 588). For the purpose of analysis, the population was divided into a high risk and a low risk group for HBP based on maternal ethnicity.
