Introduction: Although prevalence of smoking in the USA has been decreasing for decades, smoking rates among low-income individuals remain elevated. Theories from behavioral economics and prior research suggest that financial stress may contribute to the difficulty that low-income smokers face in quitting. The present work is a secondary analysis of a randomized controlled trial that incorporated financial coaching and social services referrals into smoking cessation treatment. Primary analyses showed that participants randomized to the intervention (N = 208) were significantly more likely not to smoke, to have lower financial stress, and to be able to afford leisure activities (p <.05) than were control participants (N = 202). Methods: This paper investigates subgroup discrepancies in attendance of intervention sessions and in uptake of various components of this intervention through exploratory analysis. Results: Analysis using logistic regression indicated that decreased age, not having received higher education, and having income less than $1000 per month were predictive of decreased counseling attendance (p <.05). Few demographic factors were predictive of uptake of counseling components among those who attended counseling. Conclusions: These results can guide future efforts to increase participant engagement in the intervention. Trial Registration: ClinicalTrials.gov Identifier: NCT03187730.

The Par complex polarizes diverse animal cells through the concerted action of multiple regulators. Binding to the multi- PDZ domain containing protein Par-3 couples the complex to cortical flows that construct the Par membrane domain. Once localized properly, the complex is thought to transition from Par-3 to the Rho GTPase Cdc42 to activate the complex. While this transition is a critical step in Par-mediated polarity, little is known about how it occurs. Here, we used a biochemical reconstitution approach with purified, intact Par complex and qualitative binding assays and found that Par-3 and Cdc42 exhibit strong negative cooperativity for the Par complex. The energetic coupling arises from interactions between the second and third PDZ protein interaction domains of Par-3 and the aPKC Kinase-PBM (PDZ binding motif) that mediate the displacement of Cdc42 from the Par complex. Our results indicate that Par-3, Cdc42, Par-6, and aPKC are the minimal components that are sufficient for this transition to occur and that no external factors are required. Our findings provide the mechanistic framework for understanding a critical step in the regulation of Par complex polarization and activity. [ABSTRACT FROM AUTHOR] more...

CELL polarity , *BINDING site assay , *CATALYTIC domains , *BINDING energy , *PROTEIN domains - Abstract
The animal cell polarity regulator Par-3 recruits the Par complex (consisting of Par-6 and atypical PKC, aPKC) to specific sites on the cell membrane. Although numerous physical interactions have been reported between Par-3 and the Par complex, it is unclear how each of these interactions contributes to the overall binding. Using a purified, intact Par complex and a quantitative binding assay, here, we found that the energy required for this interaction is provided by the second and third PDZ protein interaction domains of Par-3. We show that both Par-3 PDZ domains bind to the PDZ-binding motif of aPKC in the Par complex, with additional binding energy contributed from the adjacent catalytic domain of aPKC. In addition to highlighting the role of Par-3 PDZ domain interactions with the aPKC kinase domain and PDZ-binding motif in stabilizing Par-3-Par complex assembly, our results indicate that each Par-3 molecule can potentially recruit two Par complexes to the membrane during cell polarization. These results provide new insights into the energetic determinants and structural stoichiometry of the Par-3-Par complex assembly. [ABSTRACT FROM AUTHOR] more...

There will be no progress in the interculturality of textbooks associated with the topic of the military occupation of the Araucanía region if attention is only paid to political or social matters. The environment should also be included. This study provides an environmental analysis of secondary education textbooks that cover this content on the history of Chile. A mixed research strategy and a multiple research design were employed. The sample was composed of eight textbooks used in the secondary school subject of History and Geography from 2008 to 2021. The data were subjected to a quantitative content analysis and a documentary analysis. The results show that there is only limited representation of biodiversity and ecosystems, as well as a lack of didactic activities that foster environmentally friendly behavior and attitudes among students. More importantly, the environment is addressed from an anthropocentric perspective, which does not consider the biocentric environmental relationship that tends to characterize aboriginal peoples and, in this case, the Mapuche people. A more effective link with the tenets of environmental history and environmental education could correct these biases. This would foster methodologies that are more focused on human diversity, the role of the environment in human history would be highlighted, and the content of textbooks would be aligned with the sustainability that is required in the modern world.

Objectives: Guidelines recommend that smokers participate in four or more counseling sessions when trying to quit, but smokers rarely engage in multiple sessions. The "decoy effect" is a cognitive bias that can cause consumer preferences for a "target" product to change when presented with a similar but inferior product (a "decoy"). This study tested the use of a decoy to guide smokers' selection of a target number of counseling sessions. During an online survey, adult tobacco users (N = 93) were randomized to one of two groups that determined the answer choices they saw in response to a question assessing their interest in multi-session cessation counseling. Group A choose between two sessions or a "target" of five sessions. Group B was given a third "decoy" option of seven sessions. Binary logistic regression was used to compare groups on the proportion of participants selecting the "target." Results: Among 90 participants with complete data, a decoy effect was not found. There was no significant difference between groups in the proportion of participants selecting the target of five sessions (47% in Group B vs. 53% in Group A; aOR = 0.76, 95%CI 0.48–1.19). Trial Registration This study was retrospectively registered at clinicaltrials.gov on December 13, 2019 (NCT04200157) [ABSTRACT FROM AUTHOR] more...

- Abstract
The research reported in this article corresponds to the results of a documentary analysis (Galeano, 2012) of "The academic writing in context: possibility of professional development of university professors". The study aims, on the one hand, to identify, through research in academic writing, the different theoretical and methodological perspectives, and, on the other hand, to analyze the relationship that exists between academic writing and the professional development of university professor. To this end, 50 documents dating from 2006 to 2016 were analyzed and published in different countries, such as Chile, Colombia, Mexico, Portugal, Argentina, Venezuela, the United States, Spain and Canada. The results show the interest of the researchers due to the difficulties that exist in the writing process, the scriptural formation of the university professor, the writing as a complex task, the use of academic writing, the explanations to the problems of reading and writing in the student leaving aside teachers, and student learning and teachers' didactics.

Trisomy and triploidy, defined as the presence of a third copy of one or all chromosomes, respectively, are deleterious in many species including humans. Previous studies have demonstrated that Caenorhabditis elegans with a third copy of the X chromosome are viable and fertile. However, the extra X chromosome was shown to preferentially segregate into the first polar body during oocyte meiosis to produce a higher frequency of euploid offspring than would be generated by random segregation. Here, we demonstrate that extra autosomes are preferentially eliminated by triploid C. elegans and trisomy IV C. elegans. Live imaging of anaphase-lagging chromosomes and analysis of REC-8 staining of metaphase II spindles revealed that, in triploids, some univalent chromosomes do not lose cohesion and preferentially segregate intact into the first polar body during anaphase I, whereas other autosomes segregate chromatids equationally at anaphase I and eliminate some of the resulting single chromatids during anaphase II. We also demonstrate asymmetry in the anaphase spindle, which may contribute to the asymmetric segregation. This study reveals a pathway that allows aneuploid parents to produce euploid offspring at higher than random frequency. [ABSTRACT FROM AUTHOR] more...

Genocide is included in most Latin American Criminal Codes that were enacted long before the adoption of the Rome Statute. Genocide's criminalization in Latin America has, to a large extent, deviated from the Genocide Convention definition with respect to the actus reus, mainly concerning the protected groups. However, the existing jurisprudence does not shed much light on the reasons or justifications for such a deviation; it is rather inconsistent in some instances. The implementation of the Rome Statute offers mixed signals as to the legal and policy trends in Latin America with regard to the scope of genocide. The fact that the codification of crimes against humanity has gained momentum with the entry into force of the Rome Statute implies an increasing need to reflect on the coherence of the domestic criminalization of core crimes.

Purpose: To identify rates and sociodemographic correlates of food insecurity among low-income smokers.Design: Cross-sectional analysis of baseline survey data from a randomized controlled trial (N = 403) testing a smoking cessation intervention for low-income smokers.Setting: Two safety-net hospitals in New York City.Sample: Current smokers with annual household income <200% of the federal poverty level.Measures: Food insecurity was measured using the United States Department of Agriculture 6-item food security module. Participant sociodemographics were assessed by self-reported survey responses.Analysis: We used frequencies to calculate the proportion of smokers experiencing food insecurity and multivariable logistic regression to identify factors associated with being food insecure.Results: Fifty-eight percent of participants were food insecure, with 29% reporting very high food insecurity. Compared to married participants, separated, widowed, or divorced participants were more likely to be food insecure (adjusted odds ratio [AOR] = 2.33, 95% confidence interval [CI]: 1.25-4.33), as were never married participants (AOR = 2.81, 95% CI: 1.54-5.14).Conclusions: Health promotion approaches that target multiple health risks (eg, smoking and food access) may be needed for low-income populations. Interventions which seek to alleviate food insecurity may benefit from targeting socially isolated smokers. [ABSTRACT FROM AUTHOR] more...- Published

Drosophila neural stem cells, or neuroblasts, rapidly proliferate during embryonic and larval development to populate the central nervous system. Neuroblasts divide asymmetrically to create cellular diversity, with each division producing one sibling cell that retains the neuroblast fate and another that differentiates into glia or neurons. This asymmetric outcome is mediated by the transient polarization of numerous factors to the cell cortex during mitosis. The powerful genetics and outstanding imaging tractability of the neuroblast make it an excellent model system for studying the mechanisms of cell polarity. This Cell Science at a Glance article and the accompanying poster explore the phases of the neuroblast polarity cycle and the regulatory circuits that control them. We discuss the key features of the cycle - the targeted recruitment of proteins to specific regions of the plasma membrane and multiple phases of highly dynamic actomyosin-dependent cortical flows that pattern both protein distribution and membrane structure.

Every war has them: a few searing images caught on film that come to epitomize the conflict. There's a war going on in Memphis right now, and a third of the way into ''Babyland,'' Friday's installment of ''20/20'' on ABC, there is such an image: workers with a steam shovel burying tiny coffins in a mass grave. The program is about infant mortality. The United States, we are told, fares poorly among industrialized nations in its survival rate for infants, and the problem is particularly acute in Memphis. ''A baby dies in Memphis every 43 hours,'' Elizabeth Vargas, who reports the segment, says. [ABSTRACT FROM PUBLISHER] more...

Background: Financial distress is a barrier to cessation among low-income smokers.Objective: To evaluate an intervention that integrated financial coaching and benefits referrals into a smoking cessation program for low-income smokers.Design: Randomized waitlist control trial conducted from 2017 to 2019.Participants: Adult New York City residents were eligible if they reported past 30-day cigarette smoking, had income below 200% of the federal poverty level, spoke English or Spanish, and managed their own funds. Pregnant or breastfeeding people were excluded. Participants were recruited from two medical centers and from the community.Intervention: The intervention (n = 208) offered smoking cessation coaching, nicotine replacement therapy, money management coaching, and referral to financial benefits and empowerment services. The waitlist control (n=202) was usual care during a 6-month waiting period.Main Measures: Treatment engagement, self-reported 7-day abstinence, and financial stress at 6 months.Key Results: At 6 months, intervention participants reported higher abstinence (17% vs. 9%, P=0.03), lower stress about finances (β, -0.8 [SE, 0.4], P=0.02), and reduced frequency of being unable to afford activities (β, -0.8 [SE, 0.4], P=0.04). Outcomes were stronger among participants recruited from the medical centers (versus from the community). Among medical center participants, the intervention was associated with higher abstinence (20% vs. 8%, P=0.01), higher satisfaction with present financial situation (β, 1.0 [SE, 0.4], P=0.01), reduced frequency of being unable to afford activities (β, -1.0 [SE, 0.5], P=0.04), reduced frequency in getting by paycheck-to-paycheck (β, -1.0 [SE, 0.4], P=0.03), and lower stress about finances in general (β, -1.0 [SE, 0.4], P = 0.02). There were no group differences in outcomes among people recruited from the community (P>0.05).Conclusions: Among low-income smokers recruited from medical centers, the intervention produced higher abstinence rates and reductions in some markers of financial distress than usual care. The intervention was not efficacious with people recruited from the community.Trial Registration: ClinicalTrials.gov Identifier: NCT03187730. [ABSTRACT FROM AUTHOR] more...- Published

Anaphase chromosome movement is thought to be mediated by pulling forces generated by end-on attachment of microtubules to the outer face of kinetochores. However, it has been suggested that during C. elegans female meiosis, anaphase is mediated by a kinetochore-independent pushing mechanism with microtubules only attached to the inner face of segregating chromosomes. We found that the kinetochore proteins KNL-1 and KNL-3 are required for preanaphase chromosome stretching, suggesting a role in pulling forces. In the absence of KNL-1,3, pairs of homologous chromosomes did not separate and did not move toward a spindle pole. Instead, each homolog pair moved together with the same spindle pole during anaphase B spindle elongation. Two masses of chromatin thus ended up at opposite spindle poles, giving the appearance of successful anaphase. [ABSTRACT FROM AUTHOR] more...

- Abstract
OBJECTIVE: To validate a new strategy to identify food groups that are associated with height. MATERIALS AND METHODS: We conducted a cross-sectional, observational, analytical and exploratory study. Length for Age and Sex [L/A/S] and 24-hour feeding data were collected from 185 healthy children 4.0 to 12.7 months of age. The proportion that each of 7 food groups contributed to total consumption were used as independent variables versus L/A/S as the dependent variable in multiple regression models. Three age groups (1 = 4-6/2 = 7-9/3 = 10-12) were evaluated. RESULTS: One age group (7-9 months) showed association with Meat, indicating that L/A/S increased with increased proportion of Meat. The age group of 10-12 months showed a negative coefficient with Breastfeeding indicating that L/A/S decreased with increased proportions of Breastfeeding. CONCLUSIONS: Our method was able to identify feeding patterns associated to growth in small groups of 47 and 77 children. We believe our approach should be expanded to other ages to gain better understanding on the relationships between feeding patterns and growth in the first years of life.

Background: Tobacco spending may exacerbate financial hardship in low-income populations by using funds that could go toward essentials. This study examined post-quit spending plans among low-income smokers and whether financial hardship was positively associated with motivation to quit in the sample. Methods: We analyzed data from the baseline survey of a randomized controlled trial testing novel a smoking cessation intervention for low-income smokers in New York City (N = 410). Linear regression was used to examine the relationship between financial distress, food insecurity, smoking-induced deprivation (SID) and motivation to quit (measured on a 0-10 scale). We performed summative content analyses of open-ended survey questions to identify the most common plans among participants with and without SID for how to use their tobacco money after quitting. Results: Participants had an average level of motivation to quit of 7.7 (SD = 2.5). Motivation to quit was not significantly related to having high financial distress or food insecurity (P >.05), but participants reporting SID had significantly lower levels of motivation to quit than those without SID (M = 7.4 versus 7.9, P =.04). Overall, participants expressed an interest in three main types of spending for after they quit: Purchases, Activities, and Savings/Investing, which could be further conceptualized as spending on Oneself or Family, and on Needs or Rewards. The top three spending plans among participants with and without SID were travel, clothing and savings. There were three needs-based spending plans unique to a small number of participants with SID: housing, health care and education. Conclusions: Financial distress and food insecurity did not enhance overall motivation to quit, while smokers with SID were less motivated to quit. Most low-income smokers, including those with SID, did not plan to use their tobacco money on household essentials after quitting. [ABSTRACT FROM AUTHOR] more...

Here, we analyzed four population‐based demographic and health surveys conducted in Bolivia between 1998 and 2016 to understand trends in anemia in children from 6 to 59 months of age by selected sociodemographic characteristics and three categories of altitude: low, medium, and high. Over the 18‐year period, the prevalence of anemia was virtually unchanged while that in children living at high altitude increased. Anemia in children living at all three altitude categories is more than 40% and a severe public health problem according to the World Health Organization. We did not identify a single consistent risk factor for anemia in children living at high altitude compared with those living at medium or low altitude. The most consistent characteristic associated with childhood anemia across the three altitude categories was diarrhea in the last 2 weeks. Low length/height for age, an adolescent or anemic mother, a mother with no or little education, and a mother who speaks Quechua or Aymara were also risk factors. We conclude that it is necessary to review anemia policies and programs and prioritize children who are at greatest risk of developing anemia, particularly those living at high altitude. As iron deficiency appears to explain only a small part of childhood anemia, there is also a need to better understand its other causes and develop appropriate interventions.
