TL;DR: In this article, a marriage market explanation is proposed to explain the link between poverty and prostitution and show that prostitution may decrease with male income if wives and prostitutes are drawn from the same pool of women.
Abstract: Prostitution is low‐skill, labor intensive, female, and well paid. This paper proposes a marriage market explanation to this puzzle. If a prostitute compromises her marriage market prospects, she will have to be compensated for forgone marriage market opportunities. We discuss the link between poverty and prostitution and show that prostitution may decrease with male income if wives and prostitutes are drawn from the same pool of women. We point to the role of male sex ratios, and males in transit, in sustaining high levels of prostitution, and we discuss possible reasons for its low reputation and implications for marriage patterns.

TL;DR: Clinical and experimental data suggest a correlation between age at disease onset, response to sodium channel blockers and the functional properties of mutations in children with SCN2A-related epilepsy, and suggest that mutations associated with early infantile epilepsy result in increased sodium channel activity with gain-of-function.
Abstract: Mutations in SCN2A, a gene encoding the voltage-gated sodium channel Nav1.2, have been associated with a spectrum of epilepsies and neurodevelopmental disorders. Here, we report the phenotypes of 71 patients and review 130 previously reported patients. We found that (i) encephalopathies with infantile/childhood onset epilepsies (≥3 months of age) occur almost as often as those with an early infantile onset (<3 months), and are thus more frequent than previously reported; (ii) distinct phenotypes can be seen within the late onset group, including myoclonic-atonic epilepsy (two patients), Lennox-Gastaut not emerging from West syndrome (two patients), and focal epilepsies with an electrical status epilepticus during slow sleep-like EEG pattern (six patients); and (iii) West syndrome constitutes a common phenotype with a major recurring mutation (p.Arg853Gln: two new and four previously reported children). Other known phenotypes include Ohtahara syndrome, epilepsy of infancy with migrating focal seizures, and intellectual disability or autism without epilepsy. To assess the response to antiepileptic therapy, we retrospectively reviewed the treatment regimen and the course of the epilepsy in 66 patients for which well-documented medical information was available. We find that the use of sodium channel blockers was often associated with clinically relevant seizure reduction or seizure freedom in children with early infantile epilepsies (<3 months), whereas other antiepileptic drugs were less effective. In contrast, sodium channel blockers were rarely effective in epilepsies with later onset (≥3 months) and sometimes induced seizure worsening. Regarding the genetic findings, truncating mutations were exclusively seen in patients with late onset epilepsies and lack of response to sodium channel blockers. Functional characterization of four selected missense mutations using whole cell patch-clamping in tsA201 cells—together with data from the literature—suggest that mutations associated with early infantile epilepsy result in increased sodium channel activity with gain-of-function, characterized by slowing of fast inactivation, acceleration of its recovery or increased persistent sodium current. Further, a good response to sodium channel blockers clinically was found to be associated with a relatively small gain-of-function. In contrast, mutations in patients with late-onset forms and an insufficient response to sodium channel blockers were associated with loss-of-function effects, including a depolarizing shift of voltage-dependent activation or a hyperpolarizing shift of channel availability (steady-state inactivation). Our clinical and experimental data suggest a correlation between age at disease onset, response to sodium channel blockers and the functional properties of mutations in children with SCN2A-related epilepsy.

TL;DR: Historical and recent aspects of reactions and mechanisms involved in the auxin-induced signalling cascade that terminates in the dramatic elongation growth of cells and plant organs are covered.
Abstract: This article will cover historical and recent aspects of reactions and mechanisms involved in the auxin-induced signalling cascade that terminates in the dramatic elongation growth of cells and plant organs Massive evidence has accumulated that the final target of auxin action is the plasma membrane H+-ATPase, which excretes H+ ions into the cell wall compartment and, in an antiport, takes up K+ ions through an inwardly rectifying K+ channel The auxin-enhanced H+ pumping lowers the cell wall pH, activates pH-sensitive enzymes and proteins within the wall, and initiates cell-wall loosening and extension growth These processes, induced by auxin or by the "super-auxin" fusicoccin, can be blocked instantly and specifically by a voltage inhibition of the H+-ATPase due to removal of K+ ions or the addition of K+-channel blockers Vice versa, H+ pumping and growth are immediately switched on by addition of K+ ions Furthermore, the treatment of segments either with auxin or with fusicoccin (which activates the H+-ATPase irreversibly) or with acid buffers (from outside) causes an identical transformation and degradation pattern of cell wall constituents during cell-wall loosening and growth These and other results described below are in agreement with the acid-growth theory of elongation growth However, objections to this theory are also discussed

TL;DR: This investigation confirms that FDG PET is the best predictor of viable residual tumor in postchemotherapy seminoma residuals and should be used as a standard tool for clinical decision making in this patient group.
Abstract: Purpose To define the clinical value of 2-18fluoro-deoxy-D-glucose positron emission tomography (FDG PET) as a predictor for viable residual tumor in postchemotherapy seminoma residuals in a prospective multicentric trial. Patients and Methods FDG PET studies in patients with metastatic pure seminoma who had radiographically defined postchemotherapy residual masses were correlated with either the histology of the resected lesion or the clinical outcome documented by computer tomography (CT), tumor markers, and/or physical examination during follow-up. The size of the residual lesions on CT, either > 3 cm or ≤ 3 cm, was correlated with the presence or absence of viable residual tumor. Results Fifty-six FDG PET scans of 51 patients were assessable. All 19 cases with residual lesions > 3 cm and 35 (95%) of 37 with residual lesions ≤ 3 cm were correctly predicted by FDG PET. The specificity, sensitivity, positive predictive value, and negative predictive value of FDG PET were 100% (95% CI, 92% to 100%), 80% (...
