miR-203 drives breast cancer cell differentiation.

A hallmark of many malignant tumors is dedifferentiated (immature) cells bearing slight or no resemblance to the normal cells from which the cancer originated. Tumor dedifferentiated cells exhibit a higher capacity to survive to chemo and radiotherapies and have the ability to incite tumor relapse. Inducing cancer cell differentiation would abolish their self-renewal and invasive capacity and could be combined with the current standard of care, especially in poorly differentiated and aggressive tumors (with worst prognosis). However, differentiation therapy is still in its early stages and the intrinsic complexity of solid tumor heterogeneity demands innovative approaches in order to be efficiently translated into the clinic. We demonstrate here that microRNA 203, a potent driver of differentiation in pluripotent stem cells (ESCs and iPSCs), promotes the differentiation of mammary gland tumor cells. Combining mouse in vivo approaches and both mouse and human-derived tridimensional organoid cultures, we report that miR-203 influences the self-renewal capacity, plasticity and differentiation potential of breast cancer cells and prevents tumor cell growth in vivo. Our work sheds light on differentiation-based antitumor therapies and offers miR-203 as a promising tool for directly confronting the tumor-maintaining and regeneration capability of cancer cells.

Subcellular positioning during cell division and cell plate formation in maize.

Introduction: During proliferative plant cell division, the new cell wall, called the cell plate, is first built in the middle of the cell and then expands outward to complete cytokinesis. This dynamic process requires coordinated movement and arrangement of the cytoskeleton and organelles. Methods: Here we use live-cell markers to track the dynamic reorganization of microtubules, nuclei, endoplasmic reticulum, and endomembrane compartments during division and the formation of the cell plate in maize leaf epidermal cells. Results: The microtubule plus-end localized protein END BINDING1 (EB1) highlighted increasing microtubule dynamicity during mitosis to support rapid changes in microtubule structures. The localization of the cell-plate specific syntaxin KNOLLE, several RAB-GTPases, as well as two plasma membrane localized proteins was assessed after treatment with the cytokinesis-specific callose-deposition inhibitor Endosidin7 (ES7) and the microtubule-disrupting herbicide chlorpropham (CIPC). While ES7 caused cell plate defects in Arabidopsis thaliana, it did not alter callose accumulation, or disrupt cell plate formation in maize. In contrast, CIPC treatment of maize epidermal cells occasionally produced irregular cell plates that split or fragmented, but did not otherwise disrupt the accumulation of cell-plate localized proteins. Discussion: Together, these markers provide a robust suite of tools to examine subcellular trafficking and organellar organization during mitosis and cell plate formation in maize.

Best Practice Strategies for Retaining Faculty During Times of Rapid Change.

Faculty retention is an issue of concern to schools and colleges of pharmacy. The reasons why faculty leave are multifactorial but often involve a breach of unwritten contract obligations between the faculty member and the organization. This article provides strategies for retaining faculty based on published literature that include perceived breaches of unwritten contracts and our own perspectives as departmental and university administrators and senior faculty members who have been involved in devising and implementing institutional change. Retention begins with recruitment but then needs to be nurtured during onboarding and as part of the overall enculturation process for new faculty members. Particular attention to the factors that influence the retention of underrepresented minorities must be incorporated to help ensure that pharmacy educators reflect the diversity of the US population.

Prophylactic fluconazole protocol in very low birth weight infants: invasive candidiasis prevention in a Latin American neonatal intensive care unit.

OBJECTIVE: To evaluate the effect of prophylactic fluconazole for very low birth weight infants (VLBWI) in a neonatal intensive care unit (NICU) with a 7.8% incidence of invasive candidiasis (IC). STUDY DESIGN: Interventional pre-post cohort study comparing 2 years with and without fluconazole prophylaxis protocol (2016-2018 = 228 infants and 2019-2021 = 125 infants). Fluconazole was administered to all extremely low birth weight infants (ELBWI) and infants with BW 1001-1500 g with risk factors or positive carrier cultures. Liver function tests were performed weekly. RESULTS: The incidence of IC decreased from 7.8% to 2.4% (OR:0.3, p = 0.05) with the use of prophylactic fluconazole for VLBWI and in ELBWI decreased from 16,7% to 3,7% (OR:0.1, p = 0.04). No significant differences were seen in mortality. CONCLUSIONS: Fluconazole is a safe, effective, and feasible strategy to prevent IC in a Latin American country.

Community Science Reveals High Diversity of Nectaring Plants Visited by Painted Lady Butterflies (Lepidoptera: Nymphalidae) in California Sage Scrub.

California's sage scrub habitats support a diversity of nectar and host plants for migrating and resident populations of painted lady butterflies (Vanessa cardui) throughout all seasons. North America experiences spring V. cardui migrations involving butterflies totaling in the millions in some years. These irruptive years are thought to be driven by winter weather patterns at breeding grounds near the US-Mexico border and due to their irregularity, it is difficult to study floral resource use along the migration route. Here we used the community science platform iNaturalist to quantify patterns in V. cardui nectar resource use in sage scrub over time and space during irruptive and nonirruptive years. We identified over 329 different nectaring plant species of varying functional types (72% native to California) visited by adult V. cardui, 195 of which had not been previously identified as known nectar plants for V. cardui. Vanessa cardui butterflies were observed in similar locations regardless of whether an irruptive migration occurred, indicating the presence of either sparse migrants or resident populations across California. Moreover, irruptive years were positively correlated with warmer and wetter local conditions at observation locations. Our results provide new insights into patterns of floral resource use by North American V. cardui by harnessing the power of community science data and while highlighting the factors associated with its North American migration.

[Prenatal diagnosis and early neonatal management of patients with hypoplastic left heart syndrome: Experience of a perinatal center]. / Diagnóstico prenatal y manejo neonatal precoz de pacientes con Síndrome de corazón izquierdo hipoplásico: Experiencia de un centro perinatal.

INTRODUCTION: Hypoplastic Left Heart Syndrome (HLHS) is the most common form of functional single-ventricle heart disease. Despite improvements in medical and surgical care, morbidity and mortality remain high, especially around the first surgical stage. OBJECTIVE: To describe the clinical characteristics of newborns with HLHS, seen at a perinatal referral center. PATIENTS AND METHOD: Retrospective des criptive study of all newborns with pre and/or postnatal diagnosis of HLHS between 2014 and 2019 in the Complejo Asistencial Dr. Sótero del Rio. Medical records were reviewed collecting demographic and perinatal variables, clinical evolution, mortality associated with the first surgery, and survival at one year. RESULTS: Nineteen patients were included. Most were term newborns and 13/19 were fema le. All had a prenatal diagnosis. Five patients had associated extracardiac anomalies. 16/19 required vasoactive drugs and 17/19 used invasive mechanical ventilation. Seven patients received enteral fe eding, without episodes of enterocolitis. The median age at transfer for surgery was 8 days. Thirteen patients underwent the Norwood procedure, with 31% of mortality, and 47% of survival at one year. CONCLUSIONS: Neonatal management of patients with HLHS is complex and the multidisciplinary approach is fundamental. Mortality around the first surgical stage of our cohort is greater than the international reports which could be influenced by the absence of fetal therapy and the higher inci dence of extracardiac malformations.

Expanding the Trichoderma harzianum species complex: Three new species from Argentine natural and cultivated ecosystems.

A study was performed on a collection of 84 isolates from decaying plant tissues and soils in Argentina previously identified as Trichoderma harzianum. Based on multiple phenotypic characters and multilocus phylogenetic analyses, 10 species were distinguished, three of which are described as new species: T. austroindianum, T. hortense, and T. syagri. Among the remaining seven identified species, the following five can be added to the Argentine mycobiota: T. afarasin, T. afroharzianum, T. endophyticum, T. guizhouense, and T. neotropicale. Trichoderma afroharzianum and T. endophyticum were the most frequent species found in the samples. In addition, a collection of isolates previously identified as T. harzianum with antagonistic abilities were reidentified as T. afroharzianum, thus highlighting the importance of correct identification of biocontrol species.

Innovation, entrepreneurship, promotion, and tenure.

Academic incentives must reward broader societal impacts.

Equity for and Inclusion of Non-Tenure-Track Pharmacy Faculty Within Academia.

Although there are at least twice as many non-tenure-track first-time pharmacy faculty as tenured and tenure-track first-time pharmacy faculty entering academia based on data collected from 2013 to 2019, there are ongoing equity, inclusion, and advancement issues between these categories of faculty that require consideration. Contracts with clear descriptions of responsibilities are needed along with regular evaluations and promotion opportunities based on the faculty member's performance of the assigned responsibilities, appropriate compensation including fringe benefits, inclusion in institutional voting and governance, and due process protections against abrupt termination. Further, universities and schools and colleges of pharmacy should foster a culture that values all faculty regardless of rank or position. The purpose of this commentary is to describe ongoing efforts and lessons learned by one public university with a college of pharmacy that has non-tenure-track and tenure-track faculty. Our hope is to provide insight into how these experiences could be used as a basis to inform changes in policy by other universities with a school or college of pharmacy, as well as to inform possible changes to the Academy's policies.

Identification of genes affecting milk fat and fatty acid composition in Vrindavani crossbred cattle using 50 K SNP-Chip.

The aim of this study was to identify candidate genes associated with milk fat per cent and fatty acid (FA) composition in Vrindavani cattle using the Illumina 50 K single-nucleotide polymorphism (SNP) array. After quality control, a total of 41,427 informative and high-quality SNPs were used for a genome-wide association study (GWAS) for milk fat percentage and 16 different types of fatty acids. Lactation stage, parity, test day milk yield, and proportion of exotic inheritance were included as fixed effects in the GWAS model. A total of 67 genome-wide significant (P < 1.20 × 10-06) SNPs and 176 suggestive significant (P < 2.41 × 10-05) SNPs were identified. Out of these, 15 SNPs were associated with more than one trait. The strongest associations were found on BTA14 for milk fat percentage and on BTA2 and BTA16 for polyunsaturated fatty acids. Several significant SNPs were identified close to or within the genes ELOVL6, FABP4, PMP2, PLIN1, MFGE8, GHRL2, and LDLRAD3 which are known to be associated with fat percentage and FA composition in dairy cattle breeds. This study is a step forward to better characterize the molecular mechanisms of phenotypic variation in milk fatty acids in a taurine-indicine composite cattle breed reared in tropical environments.

Donor-Site Morbidity Following Free Fibula Flap Harvest for Mandibular or Maxillary Reconstruction in Pediatric Patients.

INTRO AND AIM: The morbidity at the donor-site in the free fibula flap is a well-studied fact in the adult population, but in children, there are few reports of the long-term adverse effects at the donor site. In this study, we evaluate donor-site morbidity, complications, and functional outcome in pediatric patients undergoing free fibula flap harvest for mandibular or maxillary reconstruction, and the relation between pain and walking abilities. METHODS: A retrospective study of 22 pediatric patients undergoing free fibula flap harvest for mandibular and maxillary reconstruction between 2003 and 2014 was conducted. A certified point evaluation system was used, analyzing several factors like pain, walking ability, restriction in activities, gait alteration, paresthesia, and cosmetic appearance, and the relationship between variables. RESULTS: Mean age follow up of patient was 8.5 years (range 2-13 years). Pain was reported in 27% (n = 6), paresthesia and numbness 9% (n = 2), walking ability alteration in 50% (n = 11), restriction in activities in 18% (n = 4), gait alteration in 23% (n = 5), and cosmetic appearance alteration in the 14% (n = 3). We compare the pain and the gait alteration and did not find any relation between pain and gait alteration (P = 0.6016) and there was no relation between restriction in activities and walking ability (P = 0.1455). CONCLUSION: Free fibula flap is the gold standard for head and neck reconstruction, but the morbidity at the donor site, especially in a growing child, should not be ignored or minimized when counseling patients and their families.More studies, with more population and with a long-term follow-up should be carried out to determine the impact on the daily activities on the pediatric population.

Counterstory methodology in a university-high school collaboration to center and humanize Latina/o voices.

Educational environments can often feel hostile and inequitable for Latina/o students and teachers, with limited resources and support to humanize their experiences. Counterstorytelling methodologies can be used by students and teachers to center lived experiences, contest deficit narratives, and uncover community cultural wealth (CCW). Drawing on a CCW lens, situated in critical race theory and Latina/o critical theory, we examine a university-high school service learning collaboration in an urban setting that focused on educational equity and counterstorytelling (5 high school classes, 80 students, and 1 teacher; 1 university class, 29 undergraduates, 1 graduate student, and 1 university professor) using ethnographic observations and reflections. In a context of relationship building and discussions of educational equity across the university-high school partnership, we engaged in a counterstorytelling process that uncovered existing CCW and helped to cultivate positive relational pedagogy (social capital) and college going culture (aspirational and navigational capital) and fostered critical reflection and hope (resistant capital). Centering the unique knowledge of students can allow the teacher to facilitate a more equitable learning environment that acknowledges students' resilience.

[Hypomagnesemia in newborns with hypoxic ischemic encephalopathy and whole-body hypothermia]. / Hipomagnesemia en recién nacidos con encefalopatía hipóxico isquémica en hipotermia corporal total.

INTRODUCTION: In newborns with the diagnosis of hypoxic-ischemic encephalopathy (HIE) treated with hypother mia, metabolic alterations are observed, which are associated with neurological prognosis. Hypo magnesemia has been reported frequently in the literature in these patients, but it is not measured or corrected in all neonatal healthcare centers. OBJECTIVE: To evaluate the frequency of hypomag nesemia and hypocalcemia in newborns with HIE treated with whole-body hypothermia and to evaluate the response to the magnesium sulfate administration. PATIENTS AND METHOD: Prospective, observational and descriptive study in hospitalized newborns with the diagnosis of HIE and trea ted with whole-body hypothermia between the years 2016 and 2017. Serial blood measurement of magnesemia (Mg) and calcemia (Ca) was performed. When presenting an Mg level < 1.8 mg/dl, supplementation with magnesium sulfate was administered to maintain levels between 1.9 and 2.8 mg/dl. The frecuency of hypomagnesemia, hypocalcemia and clinical evolution was registered. A descriptive statistical analysis was performed, with central tendency measures. RESULTS: Sixteen ca ses were included, 13 of them presented hypomagnesemia (81.3%), with early-onset (6-36 hours of life), which was normalized with magnesium sulfate treatment, receiving a second dose 4 patients. Six of 16 patients presented hypocalcemia (37.5 %). CONCLUSIONS: Hypomagnesemia is frequent (80%), similar to that described in the literature, and should be controlled and corrected early, given its physiological role, in the same way that calcium is controlled.

Conversion of 3-amino-4-arylamino-1H-isochromen-1-ones to 1-arylisochromeno[3,4-d][1,2,3]triazol-5(1H)-ones: synthesis, spectroscopic characterization and the structures of four products and one ring-opened derivative.

An efficient synthesis of 1-arylisochromeno[3,4-d][1,2,3]triazol-5(1H)-ones, involving the diazotization of 3-amino-4-arylamino-1H-isochromen-1-ones in weakly acidic solution, has been developed and the spectroscopic characterization and crystal structures of four examples are reported. The molecules of 1-phenylisochromeno[3,4-d][1,2,3]triazol-5(1H)-one, C15H9N3O2, (I), are linked into sheets by a combination of C-H...N and C-H...O hydrogen bonds, while the structures of 1-(2-methylphenyl)isochromeno[3,4-d][1,2,3]triazol-5(1H)-one, C16H11N3O2, (II), and 1-(3-chlorophenyl)isochromeno[3,4-d][1,2,3]triazol-5(1H)-one, C15H8ClN3O2, (III), each contain just one hydrogen bond which links the molecules into simple chains, which are further linked into sheets by π-stacking interactions in (II) but not in (III). In the structure of 1-(4-chlorophenyl)isochromeno[3,4-d][1,2,3]triazol-5(1H)-one, (IV), isomeric with (III), a combination of C-H...O and C-H...π(arene) hydrogen bonds links the molecules into sheets. When compound (II) was exposed to a strong acid in methanol, quantitative conversion occurred to give the ring-opened transesterification product methyl 2-[4-hydroxy-1-(2-methylphenyl)-1H-1,2,3-triazol-5-yl]benzoate, C17H15N3O3, (V), where the molecules are linked by paired O-H...O hydrogen bonds to form centrosymmetric dimers.

Disentangling relationships between bicultural stress and mental well-being among Latinx immigrant adolescents.

BACKGROUND: The Acculturative Process and Context Framework (Ward & Geeraert, 2016) proposes that acculturative stressors influence psychological well-being over time. In fact, extant literature has linked bicultural stress with psychological functioning; yet, no studies have explored the causal dominance of bicultural stress. The purpose of the present study was to evaluate the directionality of prospective relations among bicultural stress and psychosocial functioning (i.e., depressive symptoms, hopefulness, and self-esteem) in Latinx immigrant adolescents across 5 waves. METHOD: There were 303 Latinx adolescents who were recruited for this study from Los Angeles and Miami and were assessed across 5 waves at 6-month intervals. Adolescents were 14.50 years old on average (SD = .88) and 53.16% were male. Adolescents reported living in the United States for 2.07 years on average (SD = 1.87). A Random-Intercept Cross-Lagged Panel Model (RI-CLPM) was used to examine the between- and within-person relations among bicultural stress, depressive symptoms, hopefulness, and self-esteem in a comprehensive model. RESULTS: The comprehensive RI-CLPM including bicultural stress, depressive symptoms, hopefulness, and self-esteem exhibited excellent model fit. Between-person, trait-like relations among constructs ranged from small to large, as expected. Within-person, cross-lagged estimates among constructs were overall inconsistent, with some evidence that, within individuals, self-esteem influences later hopefulness. CONCLUSION: Findings from this study indicate that the RI-CLPM is an effective strategy to examine bicultural stress and well-being processes among adolescents. There is a need for further research examining bicultural stress among Latinx immigrant youth, particularly within prevention and intervention studies.

Reflections from novice youth participatory action researchers: Emphasis on critical gender perspectives.

Rooted in multiracial feminist theory, this research investigated the roles of adults engaged in youth participatory action research (YPAR) projects focused on developing critical perspectives of gender, power, and critical hope with the youth of color. Across 10 weeks, two novice adult facilitators documented ethnographic observations (i.e., voice memos) of their experiences collaborating with youth in YPAR. Voice memos were transcribed and coded for emergent themes. Our findings highlight how we deconstructed adultism, prioritized humanizing youth, and integrated critical gender perspectives to understand gender as a mechanism of systemic oppression. Our purpose was to capture moments of breakthroughs, realizations, and tensions as scholars contending with inexperience in YPAR and share our journey with other researchers interested in YPAR. We provide recommendations for adults to develop pathways towards humanity for the youth of color, collective resistance and take social justice action steps towards a critically hopeful future.
