Background: Kangaroo m.ther Care is a sim.le safe m.thod used to care for low-birth-weight babies. Low-birth-weight is a global public health issue that pose significant challenge to perinatal care system.. Globally, com.lications due to low-birth-weight are the leading cause of neonatal m.rtality, resulting in an estim.ted 1 m.llion deaths annually. Kangaroo m.ther Care (Km.) is a low-cost m.thod of care for low-birth-weight infants in areas with inadequate incubators and power outages with positive outcom.s. Objectives: To assess factors influencing acceptability of Kangaroo m.ther Care (Km.) in NICU at Arthur Davison Children’s Hospital in Ndola, Zam.ia. m.thodology: A cross sectional quantitative analytical study design was used. The study was conducted at Arthur Davison Children’s Hospital (ADCH) in Ndola, Zam.ia. The purposive sam.ling m.thod was used to select the study participants and a total of 129 m.thers with Low Weight Babies A were selected to participate structured closed ended questionnaire was used to collect data from.the participants using an interview. Data was analyzed using a Statistical Package for Social Scientists (SPSS) software version 26. Cross tabulations were done to determ.ne association of variables using a Chi square (x2) test at 95% confidence interval and were assum.tions where not m.t, fishers exact test was used. m.ltivariate binary logistic regression analysis was used to quantify the relationship between the dependent and independent variables. Results: m.st of the respondents had m.le babies 77%, 69% of the babies weighed 1000 g - 1400 g, m.jority 79% had norm.l delivery, 71% of the respondents were m.ltigravida and m.st of the respondents 79% were m.rried. The study reviewed that 85% of those who attained secondary education accepted Km., 74% of the respondents without m.nthly incom. accepted Km., 80% of the respondents had positive attitude and accepted Km.. 82% of the respondents who had positive perception accep

The Effects of the Longitudinal Axis of Loading upon Bending, Shear and Torsion of a Thin-Walled Cantilever Channel Beam

引用

World Journal of m.chanics 2024年第5期14卷 73-96页

作者： David W. A. Rees Abdelraouf m. Sam. Alsheikh College of Engineering and Design Brunel University Uxbridge UK

Three alum.nium.channel sections of US standard extruded dim.nsion are m.unted as cantilevers with x-axis sym.etry. The flexural bending and shear that arise with applied axial torsion are each considered theoretically and num.rically in term. of two longitudinal axes of loading not coincident with the shear centre. In particular, the warping displacem.nts, stiffness and stress distributions are calculated for torsion applied to longitudinal axes passing through the section’s centroid and its web centre. The stress conversions derived from.each action are superim.osed to reveal a net sectional stress distribution. Therein, the influence of the axis position upon the net axial and shear stress distributions is established com.ared to previous results for each beam.when loading is referred to a flexural axis through the shear centre. Within the net stress analysis is, it is shown how the constraint to free warping presented by the end fixing m.difies the axial stress. The latter can be identified with the action of a ‘bim.m.nt’ upon each thin-walled section.

The NORE1A/RASSF5 Tum.r Suppressor Form. a Com.lex with GSK-3β to Regulate β-Catenin

引用

Journal of Biosciences and m.dicines 2024年第8期12卷 60-75页

作者： m. Lee Schm.dt Howard Donninger Geoffrey J. Clark Departm.nt Pharm.cology and Toxicology University of Louisville Louisville USA US Worldm.ds LouisvilleUSA Departm.nt of m.dicine University of Louisville Louisville USA Experim.ntal Therapeutics Program James Graham Brown Cancer Center University of Louisville Louisville USA

NORE1A (RASSF5) is a tum.r suppressor of the RASSF fam.ly that is often down-regulated in hum.n tum.rs. NORE1A has m.ltiple roles in controlling cellular hom.ostasis, one of them.being regulating levels of β-catenin by binding and m.dulating the ubiquitin ligase substrate recognition factor β-TrCP. β-catenin is a m.jor executor of the Wnt pathway. The ubiquitin SCF-β-TrCP ligase com.lex acts on a phospho-degron site in β-catenin that can be phosphorylated by GSK-3β. We now show that in addition to binding β-TrCP, NORE1A also prom.tes the phosphorylation of the β-catenin phospho-degron by com.lexing with the kinase GSK-3β. Indeed, NORE1A enhances the form.tion of a GSK-3β/β-TrCP com.lex. A structural m.tant of NORE1A that retains β-TrCP binding but will no longer interact with GSK-3β inhibits the β-catenin degrading action of NORE1A. The GSK-3β interaction with NORE1A plays an im.ortant role in the biology of NORE1A as a GSK-3β inhibitor blocks NORE1A induced senescence. Thus, we identify a new role for the tum.r suppressor NORE1A: The regulation of GSK-3β. GSK-3β has m.ny other substrates including m.ltiple transcription factors and co-activators such as p53 and the Hippo com.onent TAZ. The work im.lies that NORE1A m.y be able to influence all of them.via this new kinase scaffolding interaction.

Quantifying the Im.act of In-Cab Alerts on Truck Speed Reductions in Ohio

引用

Journal of Transportation Technologies 2024年第3期14卷 273-288页

作者： Jairaj Desai Jijo K. m.thew Darcy m. Bullock Lyles School of Civil Engineering Purdue University West Lafayette IN USA

In-cab alerts warn com.ercial vehicle drivers of upcom.ng roadway incidents, slowdowns and work zone construction activities. This paper reports on a study evaluating the driver response to in-cab alerts in Ohio. Driver response was evaluated by m.asuring the statistical trends of vehicle speeds after the in-cab alerts were received. Vehicle speeds pre and post in-cab alert were collected over a 47 day period in the fall of 2023 for trucks traveling on interstate roadways in Ohio. Results show that approxim.tely 22% of drivers receiving Dangerous Slowdown alerts had reduced their speeds by at least 5 m.h 30 seconds after receiving such an alert. Segm.nting this analysis by speed found that of vehicles traveling at or above 70 m.h at the tim. of alerting, 26% reduced speeds by at least 5 m.h. These speed reductions suggest drivers taking actional m.asures after receiving alerts. Future studies will involve further analysis on the im.act of the types of alerts shown, roadway characteristics and overall traffic conditions on truck speeds passing through work zones.

Esophageal perforation, a rare condition, can arise from.iatrogenic, traum.tic, or spontaneous origins. Even when therapy is initiated within the first 24 hours, it is associated with a m.rtality rate of up to 25%. Due to the varied initial presentation, treatm.nt m.y be delayed, leading to poorer outcom.s. Here, we present a unique case of a 27-year-old schizophrenic patient who initially presented with acute respiratory failure and septic shock and was ultim.tely diagnosed with cavitary pneum.nia secondary to esophageal perforation.
