Statistical approaches for assessing meat quality and heifer rumen histology based on dietary forage.

Introduction: Feeding local forages to ruminants is a promising strategy for enhancing metabolic processes, promoting sustainable farming, and improving product quality. However, studies comparing the effects of different forages on rumen histology and meat attributes of heifers are limited and variable.

Material And Methods: This study evaluated the benefits of incorporating local forages into heifer diets by comparing barley straw (BS) and oat hay (OH) on heifer attributes focusing on meat quality (MQ) and rumen status (RS).

Multivariate Statistical Techniques: A New Approach to Identify the Commercial Properties of Mixtures of Flours of and Cocoa Pod Husk.

is known to show high nutritional and organoleptic properties and can be mixed with different by-products in the production of new foods with important functional characteristics. Cocoa pod husk (CPH) is the main by-product in the cocoa industry and presents important bioactivities. In this research, two mixtures were applied based on mushroom flour from fifty different strains (strain 1 to strain 50) and cocoa pod husk flour (CPHF): 60% mushroom flour from each strain mixed with 40% CPHF (Mixture 1), and 80% mushroom flour from each strain mixed with 20% CPHF (Mixture 2).

New cut-off points of PHQ-9 and its variants, in Costa Rica: a nationwide observational study.

The PHQ-9 questionnaire is a screening test worldwide used to measure depression. But it cannot be used in Costa Rica, due to the fact that it has not previously been validated for its population. The present study aims to show the validation of the PHQ-9 questionnaire and its variants (PHQ-2, PHQ-4, PHQ-8) in a population sample of adults residing in Costa Rica.

STATIS multivariate three-way method for evaluating quality of life after corneal surgery: Methodology and case study in Costa Rica.

Vision-related quality of life (QoL) analyzes the visual function concerning individual well-being based on activity and social participation. Because QoL is a multivariate construct, a multivariate statistical method must be used to analyze this construct. In this paper, we present a methodology based on STATIS multivariate three-way methods to assess the real change in vision-related QoL for myopic patients by comparing their conditions before and after corneal surgery.

A reproducible and repeatable digital method for quantifying nasal and sinus airway changes following suture palatine expansion.

Purpose: The airway complex is modified by palatine expansion. Computer tomography has been used in the past to determine the change in volume, but there was a lack of a specific, reproducible method for this purpose. The present study sought to determine the accuracy, reproducibility, and repeatability of an innovative digital measurement technique for analyzing the volume of maxillary and nasal sinus airways following suture palatine expansion performed with the Hyrax disyuntor appliance.

Effectiveness and types of interventions to reduce mental illness-related stigma among Medical university students: A literature review (1997-2020).

There is a high prevalence of stigma among medical students towards mental illness, which can have far reaching negative consequences. It is essential to intervene and modify their preconceptions in order to fight against stigma.

Detection of response shift in health-related quality of life studies: a systematic review.

Background: Response Shift (RS) refers to the idea that an individual may undergo changes in its health-related quality of life (HRQOL). If internal standard, values, or reconceptualization of HRQOL change over time, then answer to the same items by the same individuals may not be comparable over time. Traditional measures to evaluate RS is prone to bias and strong methodologies to study the existence of this phenomenon is required.

Pain Experienced during Various Dental Procedures: Clinical Trial Comparing the Use of Traditional Syringes with the Controlled-Flow Delivery Dentapen Technique.

: Currently, one of the most discouraging aspects for many patients undergoing dental procedures is the administration of anaesthesia. Consequently, there is a constant search for new techniques to avoid the invasive and painful nature of the injection. A new motorised syringe system (Dentapen) has recently been developed, standing out for its convenience and ease of use.

Data-Mining Techniques: A New Approach to Identifying the Links among Hybrid Strains of with Culture Media.

In this study, a data set of mycelial and cultural characteristics of hybrid strains of and were analyzed using three data-mining techniques: the K-medoids clustering algorithm, PCA biplot and the association rules algorithm. The characteristics evaluated were as follows: maximum velocity; lag phase; biomass; and exopolysaccharides content in the cultivation of 50 hybrid strains of and 50 hybrid strains of Different mixtures of culture media were used to supplement Ecuadorian agricultural products. Data of the parameters obtained in the experimental methods were grouped into four clusters, obtaining a presentation of the hybrid strains of with a higher relation to each characteristic measured.

Application of K-Means Clustering Algorithm to Commercial Parameters of spp. Cultivated on Representative Agricultural Wastes from Province of Guayas.

Data of the commercial parameters of and were analyzed using the data mining technique: K-means clustering algorithm. The parameters evaluated were: biological efficiency, crop yield ratio, productivity rate, nutritional composition, antioxidant and antimicrobial activities in the production of fruit bodies of 50 strains of and 50 strains of , cultivated on the most representative agricultural wastes from the province of Guayas: 80% sugarcane bagasse and 20% wheat straw (M1), and 60% wheat straw and 40% sugarcane bagasse (M2). The database of the parameters obtained in experimental procedures was grouped into three clusters, providing a visualization of the strains with a higher relation to each parameter (vector) measured.

Childhood wheezing phenotypes and their association to perinatal factors: a longitudinal study.

Introduction: Multiple gestational and early life factors have been described as the variables that increase the risk for each phenotype of infantile wheezing. Our objective was to study the evolution of wheezing in a cohort of children followed up to 9-10 years of age and its relationship with different perinatal risk factors.

Methods: A longitudinal study was made on the evolution of wheezing, over time, in 1164 children from Salamanca (Spain) included in the International Study of Wheezing in Infants, when the children were 12 months old.
