Characterization of a recently synthesized microtubule-targeting compound that disrupts mitotic spindle poles in human cells

Author(s): Jaunky DB; Larocque K; Husser MC; Liu JT; Forgione P; Piekny A;

We reveal the effects of a new microtubule-destabilizing compound in human cells. C75 has a core thienoisoquinoline scaffold with several functional groups amenable to modification. Previously we found that sub micromolar concentrations of C75 caused cytotoxicity. We also found that C75 inhibited microtubule polymerization and competed with colchicine for ...

Simplifying and expanding the scope of boron imidazolate framework (BIF) synthesis using mechanochemistry

Author(s): Lennox CB; Do JL; Crew JG; Arhangelskis M; Titi HM; Howarth AJ; Farha OK; Frišcic T;

Mechanochemistry enables rapid access to boron imidazolate frameworks (BIFs), including ultralight materials based on Li and Cu(i) nodes, as well as new, previously unexplored systems based on Ag(i) nodes. Compared to solution methods, mechanochemistry is faster, provides materials with improved porosity, and replaces harsh reactants (e.g. n-butylithium) ...

Corticostriatal suppression of appetitive Pavlovian conditioned responding

Author(s): Villaruel FR; Martins M; Chaudhri N;

The capacity to suppress learned responses is essential for animals to adapt in dynamic environments. Extinction is a process by which animals learn to suppress conditioned responding when an expected outcome is omitted. The infralimbic cortex (IL) to nucleus accumbens shell (NAcS) neural circuit is implicated in suppressing conditioned responding after e ...

External validation of a shortened screening tool using individual participant data meta-analysis: A case study of the Patient Health Questionnaire-Dep-4

Author(s): Harel D; Levis B; Sun Y; Fischer F; Ioannidis JPA; Cuijpers P; Patten SB; Ziegelstein RC; Markham S; Benedetti A; Thombs BD;

Shortened versions of self-reported questionnaires may be used to reduce respondent burden. When shortened screening tools are used, it is desirable to maintain equivalent diagnostic accuracy to full-length forms. This manuscript presents a case study that illustrates how external data and indivi ...

The Dyadic Health Influence Model

Author(s): Huelsnitz CO; Jones RE; Simpson JA; Joyal-Desmarais K; Standen EC; Auster-Gussman LA; Rothman AJ;

Relationship partners affect one another's health outcomes through their health behaviors, yet how this occurs is not well understood. To fill this gap, we present the Dyadic Health Influence Model (DHIM). The DHIM identifies three routes through which a person (the agent) can impact the heal ...

Pre- and post-industrial levels of polycyclic aromatic hydrocarbons in sediments from the Estuary and Gulf of St. Lawrence (eastern Canada)

Author(s): Corminboeuf A; Montero-Serrano JC; St-Louis R; Dalpé A; Gélinas Y;

The concentrations of 23 polycyclic aromatic hydrocarbons (PAHs; 16 parent PAHs and 7 alkyl-PAHs) were determined in 45 surface sediment and 7 basal sediment box core samples retrieved from the Estuary and Gulf of St. Lawrence in eastern Canada. The concentration sums of 16 priority PAHs (S<sub>16</sub>PAHs) in the surface sediments (represent ...

Associations of the BDNF Val66Met Polymorphism With Body Composition, Cardiometabolic Risk Factors, and Energy Intake in Youth With Obesity: Findings From the HEARTY Study

Author(s): Goldfield GS; Walsh J; Sigal RJ; Kenny GP; Hadjiyannakis S; De Lisio M; Ngu M; Prud' homme D; Alberga AS; Doucette S; Goldfield DB; Cameron JD;

The brain-derived neurotrophic factor (BDNF) Val66Met polymorphism is functionally related to BDNF, and is associated with obesity and metabolic complications in adults, but limited research exists among adolescents. This study comparatively examined carriers and non-carriers of the BDNF Val66Met ...

The trade-off between pulse duration and power in optical excitation of midbrain dopamine neurons approximates Bloch's law

Author(s): Pallikaras V; Carter F; Velazquez-Martinez DN; Arvanitogiannis A; Shizgal P;

Optogenetic experiments reveal functional roles of specific neurons. However, functional inferences have been limited by widespread adoption of a restricted set of stimulation parameters. Broader exploration of the parameter space can deepen insight into the mapping between selective neural activity and behavior. In this way, characteristics of the activa ...

A comparison of the effect of physical activity and cognitive training on dual-task performance in older adults

Author(s): Vrinceanu T; Blanchette CA; Intzandt B; Lussier M; Pothier K; Vu TTM; Nigam A; Bosquet L; Karelis AD; Li KZH; Berryman N; Bherer L;

Objectives: Studies suggest that cognitive training and physical activity can improve age-related deficits in dual-task performances. However, both of these interventions have never been compared in the same study. This paper investigates the improvement in dual-task performance in two types of e ...

White matter correlates of sensorimotor synchronization in persistent developmental stuttering

Author(s): Jossinger S; Sares A; Zislis A; Sury D; Gracco V; Ben-Shachar M;

Introduction: Individuals with persistent developmental stuttering display deficits in aligning motor actions to external cues (i.e., sensorimotor synchronization). Diffusion imaging studies point to stuttering-associated differences in dorsal, not ventral, white matter pathways, and in the cerebellar peduncles. Here, we studied microstructural white matt ...

Caloric restriction causes a distinct reorganization of the lipidome in quiescent and non-quiescent cells of budding yeast

Author(s): Mohammad K; Orfanos E; Titorenko VI;

After budding yeast cells cultured in a nutrient-rich liquid medium with 0.2% glucose (under caloric restriction conditions) or 2% glucose (under non-caloric restriction conditions), ferment glucose to ethanol and then consume ethanol, they enter the stationary phase. The process of their chronological aging begins. At that point, the yeast culture starts ...
