Professional editorial work, especially those that have an effect on social improvements in the community, always correlates with the sustainability of the media industry and its business.
 
Opening Chromatin and Improving CRISPR / Cas9 Editing
No full textabstract: The research question explored in this thesis is how CRISPR mediated editing is influenced by artificially opened chromatin in cells. Closed chromatin poses a barrier to Cas9 binding and editing at target genes. Synthetic pioneer factors (PFs) are a promising new approach to artificially open condensed heterochromatin allowing greater access of target DNA to Cas9. The Haynes lab has constructed fusions of enzymatic chromatin-modifying domains designed to remodel chromatin and increase Cas9 editing efficiency. With a library of PFs available, this research focuses on analyzing the behavior of Cas9 in chromatin that has been artificially opened by PFs. The types and frequency of INDELs (insertions & deletions) were determined after non-homologous end joining (NHEJ) in PF and Cas9-treated cells using quantitative Sanger sequencing and Synthego’s ICE software. Furthermore, NOME-seq analysis was carried out to map nucleosome position in PF and Cas9 treated cells. Although this experiment was unsuccessful, the heat map generated with data obtained from Synthego ICE predicts a possible presence of nucleosome in the vicinity suggesting that perhaps a fully open chromatin state was not achieved. Linear Regression analysis with certain assumptions confirms that with the increase in distance downstream of cut-site, the editing frequency decreases exponentially. Nevertheless, further experimental work should be carried out to investigate this hypothesis.Dissertation/ThesisMasters Thesis Biomedical Engineering 201
Effect of maternal sensitivity on infant weight status within the first year of life in exclusively formula fed infants
No full textStatement of Problem: The global prevalence of obesity has been increasing in infants. There is evidence to support that breastfeeding is a protective factor against obesity as it promotes higher maternal sensitivity to infant hunger and satiety cues. Formula feeding has been associated with lessened maternal sensitivity, higher instances of overfeeding, as well as rapid weight gain.Objective: The purpose of this study was to determine if maternal feeding sensitivity was related to energy intake and weight-for-length status in infants. Based on the literature review, it was predicted that mothers who displayed lower levels of maternal sensitivity would have infants who have a higher energy intake, resulting in a higher weight-for-length category
Methods: A secondary data analysis was performed to examine any correlation between maternal sensitivity and feeding outcomes in the infant’s first year of life. Participants from WIC were recruited, and two-day home visits were conducted at three different time points. On the first day, interviews were conducted in which mothers were asked about feeding practices, infant activity, and fussiness. Diet recalls were also filled out by the mothers. On the second day, a trained research assistant weighed and measured the infant. The mother and the infant were observed during a feeding session and the behaviors of both were recorded using NCAST feeding scales.
Results: No significant correlations between NCAST scores and kcal intake at 6-months were found. However, higher NCAST infant responsiveness at 6-months predicted lower caloric intake at 12-months. Infant weight-for-length percentile at 6-months was the only variable that was significantly predictive of infant weight for length percentile at 12-months.
Conclusions: In the present study, maternal sensitivity did not play a significant role in predicting weight gain during the first year of life. Instead, higher infant responsiveness was associated with lower caloric intake. Infant weight-for-length percentile at 6 months was the only predictor of weight-for-length at 12 months. Apart from maternal sensitivity, the contribution of the infant should be given added credence when examining the factors that play a role in rapid infant weight gain during the first year of life.

Microcontroller-Based Automated Cloth Folding Machine for Domestic and Industrial Textile Applications
No full textManual cloth folding is a repetitive and time-consuming process that limits productivity and efficiency in both domestic and industrial contexts. This work presents the design and implementation of a microcontroller-based automatic T-shirt folding machine aimed at achieving a fully autonomous operation without manual intervention. The proposed system employs lightweight acrylic boards for structural strength and portability. It integrates sensors to ensure precise garment detection and controlled folding operations. Experimental evaluation demonstrates a folding time of 9.2 seconds per shirt, ensuring operational efficiency and precision. The system effectively addresses the limitations of previous designs, particularly in terms of automation, sensing capability, and user safety, and provides a scalable foundation for future advancements in automated garment handling
Analysis of scientific publications by professors of a Faculty of Medical Sciences
No full textIntroduction: scientific publications are considered the final step of a research and are an excellent tool to characterize the scientific output of a university. Objective: to characterize the scientific production of the faculty of the Faculty of Medical Sciences "Miguel Enriquez", based on their scientific publications, in the period 2016-2022. Methods: a descriptive, cross-sectional, retrospective, observational, descriptive study was carried out. The universe was constituted by the publications of the faculty professors, grouped by teaching departments. Articles, complete books and chapters, and monographs were included. The publications were analyzed according to the time of dedication of the professor to the teaching activity, and annual indexes of scientific productivity were calculated.Results: a total of 845 scientific publications were counted in a faculty composed of 444 professors from 17 teaching departments. In a quarter of them, the main author was from the Diagnostic Means department. The number of authorships per professor was 1487 during the period, with the Clinical Sciences Department standing out. Most of the works were published in journals indexed in prestigious international databases (Groups I-II), with a predominance of publications by full-time professors. The highest indicators of annual productivity, both per department and per professor, were obtained by the Diagnostic Means and Graduate and Research departments. Professors with a scientific degree and full professors and researchers were the most productive. Conclusions: The analysis of seven years of scientific publications of the faculty of the "Miguel Enriquez" Faculty shows that there is a diminished scientific production, which mainly corresponds to the professors of higher rank or categor
Suppressing Bias Stress Degradation in High Performance Solution Processed Organic Transistors Operating in Air
No full textSolution processed organic field effect transistors can become ubiquitous in flexible optoelectronics. While progress in material and device design has been astonishing, low environmental and operational stabilities remain longstanding problems obstructing their immediate deployment in real world applications. Here, we introduce a strategy to identify the most probable and severe degradation pathways in organic transistors and then implement a method to eliminate the main sources of instabilities. Real time monitoring of the energetic distribution and transformation of electronic trap states during device operation, in conjunction with simulations, revealed the nature of traps responsible for performance degradation. With this information, we designed the most efficient encapsulation strategy for each device type, which resulted in fabrication of high performance, environmentally and operationally stable small molecule and polymeric transistors with consistent mobility and unparalleled threshold voltage shifts as low as 0.1 V under the application of high bias stress in air
Utvärdering av ett passivt exoskelett under tunnelarbetaresarbetsuppgifter ovanför axelhöjd - ett pilotprojekt inkluderandeanvändbarhet och muskelaktivitet
No full textExoskeletons have gone through an unprecedented evolution resulting in vast evaluation approaches inresearch. Within several work sectors and industries the exoskeletons show a potential in having an impact onwork-related musculoskeletal disorders by the ability to reduce musculoskeletal load. In the context of the construction sector, field assessments of exoskeletons are lacking. This study will try toexplore the current research gap by assessing a passive upper limb supporting exoskeleton in a constructionwork setting from conducting a surface electromyographic measurement and administering a usability questionnaire. Preliminary results suggest that the exoskeleton evaluated tends to reduce muscle activation but may notprovide sufficient rest time for the users to not be in the risk zone of developing MSDs. The results also showthat preliminary usability ratings are ‘Excellent’ but decreases to ‘Good’ or ‘OK’ when more time is spentwearing and using the exoskeleton. This gives an indication of a higher acceptability of the system in shortertime of usage. When considering individual differences, the exoskeleton shows a variety in the impact onmuscle activation as well as perceived usability, which aligns with previous literature. The results also hints thatfactors connected to usability such as, comfort or adaptability which might facilitate the use of exoskeletoncould be important to consider when implementing an exoskeleton, but also in early design or developmentstages. To the knowledge of the author, there is no literature in the same spirit as this one. The fact that this is a pilotstudy provides a unique exploratory research perspective into a field assessment conducted in a large-scaleconstruction project.Exoskelett har genomgått en ofantlig utveckling vilket har resulterat i omfattande utvärderingar inomforskningen.
