Grazing Cow Behavior’s Association with Mild and Moderate Lameness

peer-reviewedAccelerometer-based mobility scoring has focused on cow behaviors such as lying and walking. Accuracy levels as high as 91% have been previously reported. However, there has been limited replication of results. Here, measures previously identified as indicative of mobility, such as lying bouts and walking time, were examined. On a research farm and a commercial farm, 63 grazing cows’ behavior was monitored in four trials (16, 16, 16, and 15 cows) using leg-worn accelerometers. Seventeen good mobility (score 0), 23 imperfect mobility (score 1), and 22 mildly impaired mobility (score 2) cows were monitored. Only modest associations with activity, standing, and lying events were found. Thus, behavior monitoring appears to be insufficient to discern mildly and moderately impaired mobility of grazing cows

Validation of the Abbreviated Socio‑Political Control Scale for Youth (SPCS‑Y) Among Urban Girls of Color

This study tested and validated the factor structure of the abbreviated Sociopolitical Control Scale for Youth (SPCS-Y) among a sample of urban girls of color. Participants include (N = 830) urban girls of color from a northeastern United States community. Confirmatory Factor analyses (CFA) were conducted using AMOS Structural Equation Modeling Software. Cluster groups were created using Latent Class Cluster Analysis (LCA) and tested using Multivariate analysis of covariance (MANCOVA) with conceptually related variables. CFA results supported the two-factor structure of the abbreviated SPCS-Y among the sample. Following the creation of cluster groups, MANCOVA analyses revealed significant heterogeneity among cluster groups of participants on neighborhood sense of community, social support, ethnic identity, and lower levels of drug use. Findings support the factor structure of the SPCS-Y and its use to measure empowerment among girls of color. Results contribute significantly to the field of social work and encourages the importance of promoting strengths-based approaches among girls of color. Implications for social work practice with girls of color are conveyed in light of the need for reliable measurement tools for practitioners

Social exclusion among urban ethnic minority youth in the Northeast United States: A reflective view on community supportive structures

Social exclusion occurs as a combination of challenges (e.g., unemployment, high poverty, family conflict) that limits life opportunities. Social exclusion has been researched within European contexts, among middle-class families, and from quantitative perspectives. However, research on the topic among urban ethnic minority youth and using qualitative methodologies has remained elusive in the U.S. Although collaborative efforts between governmental institutions and community-based coalitions have helped develop intervention efforts to decrease social exclusion among youth in low-income urban areas, it continues to develop within families, communities, and societies. Therefore, this research explored experiences of social exclusion among low-income minority youth in an urban community in the Northeast U.S. Data were collected from nine focus groups (N = 58). The goal was to explore how urban ethnic minority youth understood social exclusion and the community resources they used to navigate its challenges. Findings included economic and societal exclusion in the form of economic deprivation and lack of appropriate safety nets. Although youth expressed a lack of community connection in the form of community exclusion, they applied a reflective view on how inequality shaped their lives, while discussing pathways towards social inclusion. This reflection was emphasized by the importance of developing bridging and bonding relationships (mentoring)

The American Dream eludes many urban youth of color. And they think it's their own fault.

Segregation is not a thing of the past for young people of color in the US; many attend under-resourced and segregated school districts. Despite these disadvantages, America's leaders tell young people of color that they can achieve the "American Dream" via hard work and determination. In new research, David T. Lardier Jr., Kathryn G.

Investigating episodic accretion in a very low-mass young stellar object

Very low-mass Class I protostars have been investigated very little thus far. Variability of these young stellar objects (YSOs) and whether or not they are capable of strong episodic accretion is also left relatively unstudied. We investigate accretion variability in IRS54, a Class I very low-mass protostar with a mass of M$_{\star}$ ~ 0.1 - 0.2 M$_{\odot}$. We obtained spectroscopic and photometric data with VLT/ISAAC and VLT/SINFONI in the near-infrared ($J$, $H$, and $K$ bands) across four epochs (2005, 2010, 2013, and 2014). We used accretion-tracing lines (Pa$\beta$ and Br$\gamma$) and outflow-tracing lines (H$_2$ and [FeII] to examine physical properties and kinematics of the object. A large increase in luminosity was found between the 2005 and 2013 epochs of more than 1 magnitude in the $K$ band, followed in 2014 by a steep decrease. Consistently, the mass accretion rate ($\dot{M}_{acc}$) rose by an order of magnitude from ~ 10$^{-8}$ M$_{\odot}$ yr$^{-1}$ to ~ $10^{-7}$ M$_{\odot}$ yr$^{-1}$ between the two early epochs. The visual extinction ($A_V$) has also increased from ~ 15 mag in 2005 to ~ 24 mag in 2013. This rise in $A_V$ in tandem with the increase in $\dot{M}_{acc}$ is explained by the lifting up of a large amount of dust from the disc of IRS54, following the augmented accretion and ejection activity in the YSO, which intersects our line of sight due to the almost edge-on geometry of the disc. Because of the strength and timescales involved in this dramatic increase, this event is believed to have been an accretion burst possibly similar to bursts of EXor-type objects. IRS54 is the lowest mass Class I source observed to have an accretion burst of this type, and therefore potentially one of the lowest mass EXor-type objects known so far

Characterization of Phenolic Compounds of Arnica montana Conventional Extracts

Arnica montana L. (Asteraceae family) is a plant commonly used in traditional medicine, and several reports have characterized this plant’s bioactivities, especially its phenolic compounds. These compounds are well known for their numerous beneficial biological properties. Consequently, industry stakeholders from the feed, food, cosmetic, and pharmaceutical sectors are seeking extracts rich in phenolic compounds, which could be interesting for the development of bio-based applications. The objective of the present study was to characterize the phenolic profile of this species to lay the groundwork for further optimization studies to obtain the highest amount of phenolic compounds. Therefore, A. montana was extracted with an ethanol/water ratio of 80:20 (v/v) at room temperature for 1 h, and phenolic compounds were identified and quantified through UPLC (HPLC Dionex Ultimate 3000) with a mass detector (TSQ Quantis). In the extract, phenolics belonging to different groups were identified, namely eriodictyol-O-glucuronide (flavanone), hispidulin and luteolin (flavones), kaempferol and 6-methoxykaempferol, (flavonols), p-coumaric, feruloylquinic, caffeoylquinic, and dicaffeoylquinic isomers (hydroxycinnamic acids). However, only four of them could be quantified: kaempferol and the three hydroxycinnamic acids. The total phenolic content (mg/g of dry sample) was estimated to be 27.34 mg/g, with the most prevalent compounds being the dicaffeoylquinic acids (accounting for 79.5% of the total phenolics). It has been demonstrated that dicaffeoylquinic acids present anti-inflammatory and antioxidant activities, which have been linked to several beneficial effects. Thus, obtaining phenolic-rich extracts of A. montana may allow us to exploit this plant’s significant biological properties, and it could be a new ingredient for developing new applications in the nutraceutical, cosmetic, and/or pharmaceutical industries.The research from which these results were derived was supported by MICINN via the Ramón y Cajal grant for M.A. Prieto (RYC-2017-22891) and the contract for P.

Review: Towards the agroecological management of ruminants, pigs and poultry through the development of sustainable breeding programmes. II. Breeding strategies

Agroecology uses ecological processes and local resources rather than chemical inputs to develop productive and resilient livestock and crop production systems. In this context, breeding innovations are necessary to obtain animals that are both productive and adapted to a broad range of local contexts and diversity of systems. Breeding strategies to promote agroecological systems are similar for different animal species. However, current practices differ regarding the breeding of ruminants, pigs and poultry. Ruminant breeding is still an open system where farmers continue to choose their own breeds and strategies. Conversely, pig and poultry breeding is more or less the exclusive domain of international breeding companies which supply farmers with hybrid animals. Innovations in breeding strategies must therefore be adapted to the different species. In developed countries, reorienting current breeding programmes seems to be more effective than developing programmes dedicated to agroecological systems that will struggle to be really effective because of the small size of the populations currently concerned by such systems. Particular attention needs to be paid to determining the respective usefulness of cross-breeding v. straight breeding strategies of well-adapted local breeds. While cross-breeding may offer some immediate benefits in terms of improving certain traits that enable the animals to adapt well to local environmental conditions, it may be difficult to sustain these benefits in the longer term and could also induce an important loss of genetic diversity if the initial pure-bred populations are no longer produced. As well as supporting the value of within-breed diversity, we must preserve between-breed diversity in order to maintain numerous options for adaptation to a variety of production environments and contexts. This may involve specific public policies to maintain and characterize local breeds (in terms of both phenotypes and genotypes), which could be used more effectively if they benefited from the scientific and technical resources currently available for more common breeds. Last but not least, public policies need to enable improved information concerning the genetic resources and breeding tools available for the agroecological management of livestock production systems, and facilitate its assimilation by farmers and farm technicians

Outcome of gastric electrical stimulator with and without pyloromyotomy for refractory gastroparesis.

BACKGROUND Surgical treatments of refractory gastroparesis include pyloromyotomy and gastric electrical stimulator (GES). It is unclear if patients may benefit from a combined approach with concomitant GES and pyloromyotomy. METHODS Retrospective cohort analysis of all patients with refractory gastroparesis treated with GES implantation with and without concomitant pyloromyotomy at Cleveland Clinic Florida from January 2003 to January 2023. Primary endpoint was efficacy (clinical response duration and success rate) and secondary endpoints included safety (postoperative morbidity) and length of stay. Success rate was defined as the absence of one of the following reinterventions during follow-up: Roux-en-Y gastric bypass (RYGB), pyloromyotomy, GES removal. RESULTS During a period of 20 years, 134 patients were treated with GES implantation. Three patients with history of previous surgical pyloromyotomy or RYGB were excluded from the analysis. Median follow-up was 31 months (IQR 10, 72). Forty patients (30.5%) had GES with pyloromyotomy, whereas 91 (69.5%) did not have pyloromyotomy. Most of the patients had idiopathic (n = 68, 51.9%) or diabetic (n = 58, 43.3%) gastroparesis. Except for preoperative use of opioids (47.5 vs 14.3%; p < 0.001), patient's characteristics were similar in both groups. There were no significant differences between the two groups in terms of overall postoperative complications (17.5% vs 14.3%; p = 0.610), major postoperative complications (0% vs 2.2%; p = 1), and length of stay (2(IQR 1, 2) vs 2(IQR 1, 3) days; p = 0.068). At 5 years, success rate was higher in patients with than without pyloromyotomy however not statistically significant (82% versus 62%, p = 0.066). Especially patients with diabetic gastroparesis seemed to benefit from pyloromyotomy during GES (100% versus 67%, p = 0.053). In an adjusted Cox regression, GES implantation without pyloromyotomy was associated with a 2.66 times higher risk of treatment failure compared to GES implantation with pyloromyotomy (HR 2.66, 95% CI 1.03-6.94, p = 0.044). CONCLUSION Pyloromyotomy during GES implantation for gastroparesis seems to be associated with a longer clinical response with similar postoperative morbidity and length of hospital stay than GES without pyloromyotomy. Patient with diabetic gastroparesis might benefit from a combination of GES implantation and pyloromyotomy
