Mutations in the vacuolar–type H+-ATPase B1 subunit gene ATP6V1B1 cause autosomal–recessive distal renal tubular acidosis (dRTA). We previously identified a single-nucleotide polymorphism (SNP) in the human B1 subunit (c.481G.A; p.E161K) that causes greatly diminished pump function in vitro. To investigate the effect of this SNP on urinary acidification, we conducted a genotype-phenotype analysis of recurrent stone formers in theDallas and Bern kidney stone registries. Of 555 patients examined, 32 (5.8%) were heterozygous for the p.E161K SNP, and the remaining 523 (94.2%) carried two wild–type alleles. After adjustment for sex, age, body mass index, and dietary acid and alkali intake, p.E161K SNP carriers had a nonsignificant tendency to higher urinary pH on a random diet (6.31 versus 6.09; P=0.09). Under an instructed low–Ca and low–Na diet, urinary pH was higher in p.E161K SNP carriers (6.56 versus 6.01; P,0.01). Kidney stones of p.E161K carriers were more likely to contain calcium phosphate than stones of wild-type patients. In acute NH4Cl loading, p.E161K carriers displayed a higher trough urinary pH (5.34 versus 4.89; P=0.01) than wild-type patients. Overall, 14.6% of wild-type patients and 52.4% of p.E161K carriers were unable to acidify their urine below pH 5.3 and thus, can be considered to have incomplete dRTA. In summary, our data indicate that recurrent stone formers with the vacuolar H+-ATPase B1 subunit p.E161K SNP exhibit a urinary acidification deficit with an increased prevalence of calcium phosphate– containing kidney stones. The burden of E161K heterozygosity may be a forme fruste of dRTA.

People with sequence-space synesthesia (SSS) report stable visuo-spatial forms corresponding to numbers, days, and months (amongst others). This type of synesthesia has intrigued scientists for over 130 years but the lack of an agreed upon tool for assessing it has held back research on this phenomenon. The present study builds on previous tests by measuring the consistency of spatial locations that is known to discriminate controls from synesthetes. We document, for the first time, the sensitivity and specificity of such a test and suggest a diagnostic cut-off point for discriminating between the groups based on the area bounded by different placement attempts with the same item.

FTY720 sequesters lymphocytes in secondary lymphoid organs through effects on sphingosine-1-phosphate (S1P) receptors. However, at higher doses than are required for immunosuppression, FTY720 also functions as an anticancer agent in multiple animal models. Our published work indicates that the anticancer effects of FTY720 do not depend on actions at S1P receptors but instead stem from FTY720s ability to restrict access to extracellular nutrients by down-regulating nutrient transporter proteins. This result was significant because S1P receptor activation is responsible for FTY720s dose-limiting toxicity, bradycardia, that prevents its use in cancer patients. Here, we describe diastereomeric and enantiomeric 3- and 4-C-aryl 2-hydroxymethyl pyrrolidines that are more active than the previously known analogues. Of importance is that these compounds fail to activate S1P1 or S1P3 receptors in vivo but retain inhibitory effects on nutrient transporter proteins and anticancer activity in solid tumor xenograft models. Our studies reaffirm that the anticancer activity of FTY720 does not depend upon S1P receptor activation and uphold the promise of using S1P receptor-inactive azacyclic FTY720 analogues in human cancer patients.

Coagulation factor XII (FXII) inhibitors are of interest for the study of the protease in the intrinsic coagulation pathway, for the suppression of contact activation in blood coagulation assays, and they have potential application in antithrombotic therapy. However, synthetic FXII inhibitors developed to date have weak binding affinity and/or poor selectivity. Herein, we developed a peptide macrocycle that inhibits activated FXII (FXIIa) with an inhibitory constant Ki of 22 nM and a selectivity of >2000-fold over other proteases. Sequence and structure analysis revealed that one of the two macrocyclic rings of the in vitro evolved peptide mimics the combining loop of corn trypsin inhibitor, a natural protein-based inhibitor of FXIIa. The synthetic inhibitor blocked intrinsic coagulation initiation without affecting extrinsic coagulation. Furthermore, the peptide macrocycle efficiently suppressed plasma coagulation triggered by contact of blood with sample tubes and allowed specific investigation of tissue factor initiated coagulation.

A Review of Premature Termination in Psychotherapy: Strategies for Engaging Clients and Improving Outcomes by Joshua K. Swift and Roger P. Greenberg Washington, DC: American Psychological Association. 2015. 212 pp, ISBN 978-1-4338-1801- 1. $69.95 http://dx.doi.org/10.1037/a0038612 Premature Termination in Psychotherapy: Strategies for Engaging Clients and Improving Outcomes is one of the very best examples of the new generation of psychotherapy development. Based on rigorous research findings and a deep look into the preexisting literature, this book presents practical guidelines to understand premature termination and provides evidence-based strategies for how to engage patients in treatment. It will especially be a highlight for practitioners who are interested in a broad insight of the overall empirical literature. For graduate students in clinical and counseling psychology, this book might be an excellent prototype for how to bring rigorous quantitative research and convenient practice examples together.
