Examining Baseline Relations Between Parent-Child Interactions and STEM Engagement and Learning.

Several studies suggest that children's learning and engagement with the content of play activities is affected by the ways parents and children interact. In particular, when parents are overly directive and set more goals during play with their children, their children tend to play less or are less engaged by subsequent challenges with the activity on their own. A concern, however, is that this directed interaction style is only compared with other styles of parent-child interaction, not with a baseline measure of engagement or learning.

Enabling systemic identification and functionality profiling for Cdc42 homeostatic modulators.

Maintaining body homeostasis is the ultimate key to health. There are rich resources of bioactive materials for the functionality of homeostatic modulators (HMs) from both natural and synthetic chemical repertories. HMs are powerful modern therapeutics for human diseases including neuropsychiatric diseases, mental disorders, and drug addiction (e.

Primary malignant melanoma of the genitourinary tract: case series of a rare form of primary mucosal melanoma.

Primary malignant melanoma of the genitourinary tract is extremely rare. We present two such cases in elderly Caucasian females. An 81-year-old female with urinary retention and polypoid urinary bladder mass and a 72-year-old female with gross hematuria and urethral caruncle.

Evaluation of Thermal Support during Anesthesia Induction on Body Temperature in C57BL/6 and Nude Mice.

Heat supplementation during surgery is a common practice; however, thermal support is not commonly used during anesthesia induction. Mice lose body temperature quickly, and air movement can exacerbate this, potentially putting mice at a thermal deficit before surgery. Whether the method of warming during induction affects overall heat loss during anesthesia is unknown.

Enabling Systemic Identification and Functionality Profiling for Cdc42 Homeostatic Modulators.

Unlabelled: Homeostatic modulation is pivotal in modern therapeutics. However, the discovery of bioactive materials to achieve this functionality is often random and unpredictive. Here, we enabled a systemic identification and functional classification of chemicals that elicit homeostatic modulation of signaling through Cdc42, a classical small GTPase of Ras superfamily.

From triple quandary to talent quest: The past, present, and future of A. Wade Boykin's contributions to psychology.

A. Wade Boykin's scholarship has provided key insights into the psychological realities of racially minoritized people and catalyzed revolutionary changes in psychology and education. Combining insights from personal and research experiences, Boykin authored the foundational triple quandary (TQ), a framework describing how Black Americans must navigate the often conflicting values and priorities of dominant mainstream society, the heritage culture of Black communities, and dynamics associated with being racially minoritized.

Constructs, Tape Measures, and Mercury.

This is a Lewinian-field-theory approach to understanding the Graduate Record Examination (GRE) in the context of racism to contribute to the debate about whether graduate schools should remove GRE scores from admissions processes. Woo and colleagues (this issue) review the empirical literature on bias from a psychometric perspective. In this commentary, I challenge the definition of the underlying construct measured by the GRE and offer alternative definitions of what is measured.

Pharmacological Modulators of Small GTPases of Rho Family in Neurodegenerative Diseases.

Classical Rho GTPases, including RhoA, Rac1, and Cdc42, are members of the Ras small GTPase superfamily and play essential roles in a variety of cellular functions. Rho GTPase signaling can be turned on and off by specific GEFs and GAPs, respectively. These features empower Rho GTPases and their upstream and downstream modulators as targets for scientific research and therapeutic intervention.

Intratumor δ-catenin heterogeneity driven by genomic rearrangement dictates growth factor dependent prostate cancer progression.

Only a small number of genes are bona fide oncogenes and tumor suppressors such as Ras, Myc, β-catenin, p53, and APC. However, targeting these cancer drivers frequently fail to demonstrate sustained cancer remission. Tumor heterogeneity and evolution contribute to cancer resistance and pose challenges for cancer therapy due to differential genomic rearrangement and expression driving distinct tumor responses to treatments.

Therapeutic Effect of Y-27632 on Tumorigenesis and Cisplatin-Induced Peripheral Sensory Loss through RhoA-NF-κB.

Chemotherapy-induced peripheral neuropathy (CIPN) is a major side effect of cancer therapy that frequently requires a reduction or cessation of treatments and negatively impacts the patient's quality of life. There is currently no effective means to prevent or treat CIPN. In this study, we developed and applied CIPN in an immunocompetent, syngeneic murine Lewis Lung Carcinoma (LLCab) model that enabled the elucidation of both tumor and host responses to cisplatin and treatments of Y-27632, a selective inhibitor of Rho kinase/p160.

On the prevalence of racial discrimination in the United States.

Boutwell, Nedelec, Winegard, Shackelford, Beaver, Vaughn, Barnes, & Wright (2017) published an article in this journal that interprets data from the Add Health dataset as showing that only one-quarter of individuals in the United States experience discrimination. In Study 1, we attempted to replicate Boutwell et al.'s findings using a more direct measure of discrimination.

Reducing negative affect and increasing rapport improve interracial mentorship outcomes.

Research suggests that interracial mentoring relationships are strained by negative affect and low rapport. As such, it stands to reason that strategies that decrease negative affect and increase rapport should improve these relationships. However, previous research has not tested this possibility.

National Beef Quality Audit-2016: assessment of cattle hide characteristics, offal condemnations, and carcass traits to determine the quality status of the market cow and bull beef industry.

To continue the series that began in 1994, the National Beef Quality Audit () - 2016 was conducted to quantify the quality status of the market cow and bull beef sector, as well as determine improvements made in the beef and dairy industry since 2007. The NBQA-2016 was conducted from March through December of 2016, and assessed hide-on carcasses ( = 5,278), chilled carcasses ( = 4,285), heads ( = 5,720), and offal items ( = 4,800) in 18 commercial processing facilities throughout the United States. Beef cattle were predominantly black-hided; 68.

Comparison between active (pumped) and passive (diffusive) sampling methods for formaldehyde in pathology and histology laboratories.

This study was to determine occupational exposures to formaldehyde and to compare concentrations of formaldehyde obtained by active and passive sampling methods. In one pathology and one histology laboratories, exposure measurements were collected with sets of active air samplers (Supelco LpDNPH tubes) and passive badges (ChemDisk Aldehyde Monitor 571). Sixty-six sample pairs (49 personal and 17 area) were collected and analyzed by NIOSH NMAM 2016 for active samples and OSHA Method 1007 (using the manufacturer's updated uptake rate) for passive samples.

δ-Catenin, a Wnt/β-catenin modulator, reveals inducible mutagenesis promoting cancer cell survival adaptation and metabolic reprogramming.

Mutations of Wnt/β-catenin signaling pathway has essential roles in development and cancer. Although β-catenin and adenomatous polyposis coli (APC) gene mutations are well established and are known to drive tumorigenesis, discoveries of mutations in other components of the pathway lagged, which hinders the understanding of cancer mechanisms. Here we report that δ-catenin (gene designation: CTNND2), a primarily neural member of the β-catenin superfamily that promotes canonical Wnt/β-catenin/LEF-1-mediated transcription, displays exonic mutations in human prostate cancer and promotes cancer cell survival adaptation and metabolic reprogramming.

EC144 is a potent inhibitor of the heat shock protein 90.

Alkyne 40, 5-(2-amino-4-chloro-7-((4-methoxy-3,5-dimethylpyridin-2-yl)methyl)-7H-pyrrolo[2,3-d]pyrimidin-5-yl)-2-methylpent-4-yn-2-ol (EC144), is a second generation inhibitor of heat shock protein 90 (Hsp90) and is substantially more potent in vitro and in vivo than the first generation inhibitor 14 (BIIB021) that completed phase II clinical trials. Alkyne 40 is more potent than 14 in an Hsp90α binding assay (IC(50) = 1.1 vs 5.

Structure-based design of 2,6,7-trisubstituted-7H-pyrrolo[2,3-d]pyrimidines as Aurora kinases inhibitors.

This Letter reports the optimization of a pyrrolopyrimidine series as dual inhibitors of Aurora A/B kinases. This series derived from a pyrazolopyrimidine series previously reported as inhibitors of aurora kinases and CDKs. In an effort to improve the selectivity of this chemotype, we switched to the pyrrolopyrimidine core which allowed functionalization on C-2.

Synthesis, SAR and biological evaluation of 1,6-disubstituted-1H-pyrazolo[3,4-d]pyrimidines as dual inhibitors of Aurora kinases and CDK1.

Since the early 2000s, the Aurora kinases have become major targets of oncology drug discovery particularly Aurora-A and Aurora-B kinases (AKA/AKB) for which the selective inhibition in cells lead to different phenotypes. In addition to targeting these Aurora kinases involved in mitosis, CDK1 has been added as a primary inhibition target in hopes of enhancing the cytotoxicity of our chemotypes harboring the pyrazolopyrimidine core. SAR optimization of this series using the AKA, AKB and CDK1 biochemical assays led to the discovery of the compound 7h which combines strong potency against the 3 kinases with an acceptable microsomal stability.

Design, synthesis, and biological evaluation of pyrazolopyrimidine-sulfonamides as potent multiple-mitotic kinase (MMK) inhibitors (part I).

A novel class of pyrazolopyrimidine-sulfonamides was discovered as selective dual inhibitors of aurora kinase A (AKA) and cyclin-dependent kinase 1 (CDK1). These inhibitors were originally designed based on an early lead (compound I). SAR development has led to the discovery of potent inhibitors with single digit nM IC(50)s towards both AKA and CDK1.

Cucurbitacin IIa: a novel class of anti-cancer drug inducing non-reversible actin aggregation and inhibiting survivin independent of JAK2/STAT3 phosphorylation.

Background: Cucurbitacin (Cuc) and triterpene-derived natural products exhibit anti-cancer potential in addition to their conspicuous anti-bacterial and anti-inflammatory activity. Recently, inhibition of Janus kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) signaling was shown to underlie the effects of Cuc family on inducing cell death in cancer.

Method: We purified Cuc IIa, the active component from the medicinal plant Hemsleya amalils Diels, which shows different structural modifications from other Cuc derivatives.
