Integrated structural model of the palladin-actin complex using XL-MS, docking, NMR, and SAXS.

Unlabelled: Palladin is an actin binding protein that accelerates actin polymerization and is linked to metastasis of several types of cancer. Previously, three lysine residues in an immunoglobulin-like domain of palladin have been identified as essential for actin binding. However, it is still unknown where palladin binds to F-actin.

Environmental impacts of genetically modified crops.

Genetically modified (GM) crops have been adopted by some of the world's leading agricultural nations, but the full extent of their environmental impact remains largely unknown. Although concerns regarding the direct environmental effects of GM crops have declined, GM crops have led to indirect changes in agricultural practices, including pesticide use, agricultural expansion, and cropping patterns, with profound environmental implications. Recent studies paint a nuanced picture of these environmental impacts, with mixed effects of GM crop adoption on biodiversity, deforestation, and human health that vary with the GM trait and geographic scale.

Manipulation of soil mycorrhizal fungi influences floral traits.

Most plants form root hyphal relationships with mycorrhizal fungi, especially arbuscular mycorrhizal fungi (AMF). These associations are known to positively impact plant biomass and competitive ability. However, less is known about how mycorrhizas impact other ecological interactions, such as those mediated by pollinators.

Evaluation of laboratory and on-farm tests to estimate colostrum quality for dairy cows.

The objectives of this study were to evaluate different analytical methods to determine colostrum quality in dairy cattle, including one laboratory-based method (ELISA) and 4 on-farm tests. We hypothesized that the colostral IgG concentration using different analytical methods, such as ELISA (mg/mL), digital Brix refractometer (% Brix), colostrometer (specific gravity and mg/mL), an outflow funnel (seconds), and a lateral flow assay (mg/mL), were highly correlated with the reference method, radial immunodiffusion (RID; mg/mL) and would generate comparable results. Colostrum samples were collected from 209 Holstein Friesian cows on 2 commercial dairy farms in Germany.

Colostrum insulin supplementation does not influence immunoglobulin G absorption in neonatal Holstein bulls.

Since insulin has been demonstrated to suppress IgG absorption in other neonatal species, we had the objective to delineate how colostral insulin concentrations affect IgG absorption in neonatal bovines. We enrolled Holstein bull calves (n = 48; body weight = 46.3 ± 0.

Evaluating different methods of serum collection to detect failed transfer of passive immunity in newborn calves via refractometry.

The objective of the study was to compare 4 different methods of serum collection to assess failed transfer of passive immunity (FTPI) in dairy calves. We hypothesized that centrifuged serum, filtered serum and clotted serum at room temperature, and clotted serum at refrigerator temperature measured with Brix refractometry would highly correlate with IgG concentration assessed by radial immunodiffusion (RID; gold standard) in centrifuged serum. Blood samples were collected from 321 newborn dairy calves.

The fifteenth topical meeting on Optical Interference Coatings (OIC) was held June 19-24, 2022 in Whistler, British Columbia, Canada. This feature issue of Applied Optics collects selected papers presented during this conference. The OIC topical meeting takes place every three years and is a pivotal event for the international community working in the field of optical interference coatings.

Functional comparison of full-length palladin to isolated actin binding domain.

Palladin is an actin binding protein that is specifically upregulated in metastatic cancer cells but also colocalizes with actin stress fibers in normal cells and is critical for embryonic development as well as wound healing. Of nine isoforms present in humans, only the 90 kDa isoform of palladin, comprising three immunoglobulin (Ig) domains and one proline-rich region, is ubiquitously expressed. Previous work has established that the Ig3 domain of palladin is the minimal binding site for F-actin.

Axillary lymph node recurrence following wire-directed sentinel lymph node dissection for breast cancer patients with biopsy-proven axillary metastases prior to neoadjuvant chemotherapy at a safety net medical center.

Background: Although sentinel lymph node dissection (SLND) after neoadjuvant chemotherapy (NAC) is feasible, axillary management for patients with pretreatment biopsy-proven axillary metastases and who are clinically node-negative after NAC (ycN0) remains unclear. This retrospective study was performed to determine the rate of axillary lymph node recurrence for such patients who had wire-directed (WD) SLND.

Methods: Patients treated with NAC from 2015 to 2020 had axillary nodes evaluated by pretreatment ultrasound.

Common pesticides disrupt critical ecological interactions.

Critical ecological interactions can be disrupted by pesticides, leading to serious ecosystem and economic harm. For the most part, however, the extent and magnitude of these impacts are unknown. We argue for increased investigation of ecosystem impacts of common pesticides by scientists and scrutiny by regulators.

Benign Breast Disease: Periareolar Mastitis, Granulomatous Lobular Mastitis, and Lymphocytic or Diabetic Mastopathy.

Periareolar mastitis, granulomatous lobular mastitis, and lymphocytic or diabetic mastopathy are benign inflammatory breast conditions that require specialized knowledge of the pathophysiology to reduce the morbidity from surgical management.

Impact of vaccine pause due to Thrombosis with thrombocytopenia syndrome (TTS) following vaccination with the Ad26.COV2.S vaccine manufactured by Janssen/Johnson & Johnson on vaccine hesitancy and acceptance among the unvaccinated population.

Background: In response to reports of thrombosis with thrombocytopenia syndrome (TTS) post-vaccination, the Johnson & Johnson (J&J) vaccine was paused and then restarted in April 2021. Our objective was to assess whether this pause adversely impacted vaccine confidence.

Methods: Two large internet-based surveys were conducted in the US among adults to measure knowledge, attitudes and perceptions of the J&J vaccine pause and rates of vaccine hesitancy among unvaccinated persons before, during and after the pause.

New Evidence Suggests No Sex Bias in Herbivory or Plant Defense.

AbstractDioecious plants can exhibit sexual dimorphism across a suite of plant traits, including susceptibility to herbivory and secondary chemistry. One hypothesis is that because of greater costs of reproduction in females, males should grow faster and invest less in defense, resulting in male-biased herbivory. Indeed, a series of articles and a prominent meta-analysis have established male-biased herbivory as a rule.

Riparian buffers: Disrupting the transport of E. coli from rural catchments to streams.

High levels of E. coli and associated faecal microbes in waterways as a result of agricultural and residential land use can pose environmental, human health, and economic risks. This study aims to understand the impacts of land use, climatic variables, and riparian buffers on in-stream E.

Use of Random Domain Intercept Technology to Track COVID-19 Vaccination Rates in Real Time Across the United States: Survey Study.

Background: Accurate and timely COVID-19 vaccination coverage data are vital for informing targeted, effective messaging and outreach and identifying barriers to equitable health service access. However, gathering vaccination rate data is challenging, and efforts often result in information that is either limited in scope (eg, limited to administrative data) or delayed (impeding the ability to rapidly respond). The evaluation of innovative technologies and approaches that can assist in addressing these limitations globally are needed.

Breast Trauma: A Decade of Surgical Interventions And Outcomes From us Trauma Centers.

Background: Traumatic breast injuries that require surgical intervention are rare and incompletely studied. The study objective was to define the incidence, mechanism/burden of injury, interventions, and outcomes after breast injuries requiring surgery nationally.

Methods: All patients with breast trauma necessitating surgery were identified from the National Trauma Data Bank (NTDB) (2006-2017) using ICD-9 and -10 codes, without exclusions.

Seamless Gene Correction in the Human Cystic Fibrosis Transmembrane Conductance Regulator Locus by Vector Replacement and Vector Insertion Events.

Gene correction homology directed repair (HDR) in patient-derived induced pluripotent stem (iPS) cells for regenerative medicine are becoming a more realistic approach to develop personalized and mutation-specific therapeutic strategies due to current developments in gene editing and iPSC technology. Cystic fibrosis (CF) is the most common inherited disease in the Caucasian population, caused by mutations in the CF transmembrane conductance regulator (CFTR) gene. Since CF causes significant multi-organ damage and with over 2,000 reported mutations, CF patients could be one prominent population benefiting from gene and cell therapies.

Masks, money, and mandates: A national survey on efforts to increase COVID-19 vaccination intentions in the United States.

Various efforts to increase COVID-19 vaccination rates have been employed in the United States. We sought to rapidly investigate public reactions to these efforts to increase vaccination, including self-reported responses to widespread reduced masking behavior, monetary incentive programs to get vaccinated, and work vaccination requirements. Using a unique method for data collection (Random Domain Intercept Technology), we captured a large (N = 14,152), broad-based sample of the United States Web-using population (data collected from June 30 -July 26, 2021).

The objective was to determine safety of ACS initial assessment of acute breast pathology.

Factors associated with relapse-free survival after neoadjuvant chemotherapy for breast cancer at a safety net medical center.

Background: This study was designed to assess prognostic factors associated with relapse-free survival (RFS) after neoadjuvant chemotherapy (NAC) for breast cancer.

Methods: A single-institution retrospective analysis was performed including clinical, radiographic, and pathologic parameters for all breast cancer patients treated with NAC from 2015 to 2018. All patients had pre-and post-NAC MRI.

An investigation of emotional and evaluative implicit associations with police using four versions of the Implicit Association Test.

In two studies (total = 829), we assessed civilian implicit associations with police using four modified Implicit Association Tests (IAT). Across studies and IATs, individuals harbored stronger negative implicit associations (associating police with fear/bad) than positive implicit associations (associating police with safety/good). The predictive validity of the implicit associations and magnitude of D scores varied across IAT.
