Industry requires non-destructive real-time methods for quality control of meat in order to improve production efficiency and meet consumer expectations. Near Infrared Hyperspectral Images were used for tenderness evaluation of Nellore beef and the construction of tenderness distribution maps. To investigate whether the selection of the region of interest (ROI) in the image at the exact location where the shear force core was collected improves tenderness prediction and classification models, 50 samples from Longissimus muscle were imaged (1000-2500 nm) and shear force were measured (Warner-Bratzler)...

BACKGROUND: The RARECAREnet project has updated the estimates of the burden of the 198 rare cancers in each European country. Suspecting that scant data could affect the reliability of statistical analysis, we employed a Bayesian approach to estimate the incidence of these cancers. METHODS: We analyzed about 2,000,000 rare cancers diagnosed in 2000-2007 provided by 83 population-based cancer registries from 27 European countries. We considered European incidence rates (IRs), calculated over all the data available in RARECAREnet, as a valid a priori to merge with country-specific observed data...

BACKGROUND: Breast cancer has the highest incidence in women of all cancers and its burden is expected to continue to increase worldwide, especially in middle-income countries such as Thailand. The southern region of Thailand is unique in that it is comprised of 30% Muslims, whereas the rest of Thailand is 95% Buddhist. Breast cancer incidence and survival differ between these religious groups, but the association between clinical subtype of breast cancer and survival has not yet been assessed...

For the first time, this study evaluated the use of MALDI-TOF as a typing tool for Arcobacter butzleri. A total of 104 A. butzleri strains isolated from different sources in an artisanal dairy plant in Italy were identified and typed using MALDI-TOF and compared with their multilocus sequence typing (MLST) and pulsed field gel electrophoresis (PFGE) profiles found in previous studies. MALDI-TOF correctly identified all the isolates to species level. No clearly delineated clusters appeared on dendrograms based on either the complete spectra or the significant peaks, but nine clusters were defined using the cophenetic correlation...

A secondary cervical thymus (CT) is present in the neck region in about 50% of human and mice. CT in mice is an independent and functional organ, which can be colonized by T lymphocyte progenitors and generate thymocytes that are selected by the T cell receptor repertoire following the positive and negative selection. However, CT and the main thoracic thymus (TT) have been shown in mice to have significant functional differences. In this study, we use transcriptional profiling to compare mRNA or miRNAs expression patterns in murine CT and TT...

BACKGROUND: Firefighters represent an occupational group at increased suicide risk. How suicidality develops among firefighters is poorly understood. The depression-distress amplification model posits that the effects of depression symptoms on suicide risk will be intensified in the context of anxiety sensitivity (AS) cognitive concerns. The current study tested this model among firefighters. METHODS: Overall, 831 firefighters participated (mean [SD] age = 38...

Boron (B), a trace element found in the human body, plays an important role for health of bone by promoting the proliferation and differentiation of osteoblasts. Our research group previously fabricated B-mesoporous bioactive glass (MBG) scaffolds, which successfully promoted osteogenic differentiation of osteoblasts when compared to pure MBG scaffolds without boron. However, the mechanisms of the positive effect of B-MBG scaffolds on osteogenesis remains unknown. Therefore, we performed in-vivo experiments in an OVX rat models with pure MBG scaffolds and compared them to B-MBG scaffold...

Plants maintain extensive growth flexibility under different environmental conditions, allowing them to continuously and rapidly adapt to alterations in their environment. A large portion of many plant genomes consists of transposable elements (TEs) that create new genetic variations within plant species. Different types of mutations may be created by TEs in plants. Many TEs can avoid the host's defense mechanisms and survive alterations in transposition activity, internal sequence and target site. Thus, plant genomes are expected to utilize a variety of mechanisms to tolerate TEs that are near or within genes...

Vitamin D deficiency is especially prevalent in pregnant women and children. Our recent study demonstrated that vitamin D deficiency in early life disturbed testicular development. This study investigated the effects of vitamin D deficiency in early life on prostatic hyperplasia in middle-aged mice. In control group, dams and their male pups were fed with standard-chow diets. In VDD group, dams were fed with vitamin D deficient (VDD) diets throughout pregnancy and lactation. After weaning, male pups continued to be fed with VDD diets...

The social environment of reproducing females can cause physiological changes, with consequences for reproductive investment and offspring development. These prenatal maternal effects are often found to be sex-specific and may have evolved as adaptations, maximizing fitness of male and female offspring for their future environment. Female hormone levels during reproduction are considered a potential mechanism regulating sex allocation in vertebrates: high maternal androgens have repeatedly been linked to increased investment in sons, whereas high glucocorticoid levels are usually related to increased investment in daughters...

ABC transporters are key players in drug excretion with alterations in their expression and activity by therapeutic agents potentially leading to drug-drug interactions. The interaction potential of nomegestrol acetate (NMGA), a synthetic progestogen increasingly used as oral contraceptive, had never been explored. In this work we evaluated (1) the effect of NMGA on ABC transporters in the human hepatic cell line HepG2 and (2) the underlying molecular mechanism. NMGA (5, 50 and 500 nM) increased P-glycoprotein (P-gp) expression at both protein and mRNA levels and reduced intracellular calcein accumulation, indicating an increase also in transporter activity...

The giant African snail Lissachatina fulica has been reported invading Cuba since 2014 and is now well established in areas of Havana and several nearby regions. This invasive species is of major concern to health authorities given its role as an important vector of parasites such as Angiostrongylus cantonensis, the causative agent of eosinophilic meningoencephalitis in humans. Here, we update the distribution within Cuba. We also report on our studies of experimental life-history traits to assess the population dynamics and potential for spread of this species in Cuba...

OBJECTIVE: Approximately 25% of the Czech population is currently obese. Obesity rates are expected to increase in the future. Obesity not only raises the risk of health complications for individuals, but increasing rates also represent a significant and steadily growing economic burden for healthcare systems and society as a whole. The aim of this study was to evaluate the therapeutic efficacy of three methods of bariatric surgery: laparoscopic greater curve plication (LGCP), laparoscopic sleeve gastrectomy (LSG), and Roux-en-Y gastric bypass (RYBG) in patients with type 2 diabetes mellitus (DM)...

OBJECTIVES: The aim was to explore the patterns of the coronary heart disease (CHD) mortality rates over the past almost 50 years (1968-2014) in the Czech Republic, and to predict the mortality rates in 2015-2019. METHODS: The number of deaths from CHD and the population size were stratified by sex and age. The mortality rates were age-standardized to European population. Their values in 2015-2019 were estimated using the joinpoint log-linear regression, local log-linear regression and negative binomial log-linear regression, separately for males and females...

BACKGROUND: Postural drainage is used primarily in infants with cystic fibrosis from diagnosis up to the moment when they are mature enough to actively participate in self-administered treatments. However, there is a risk of gastroesophageal reflux associated with this technique.This is an update of a review published in 2015. OBJECTIVES: To compare the effects of standard postural drainage (15º to 45º head-down tilt) with modified postural drainage (15º to 30º head-up tilt) with regard to gastroesophageal reflux in infants and young children up to six years old with cystic fibrosis in terms of safety and efficacy...

Background: Executive functioning (EF) describes a set of neurocognitive processes critical to enacting complex health behaviors. However, theoretical frameworks for understanding sexual risk behavior have generally neglected neurocognitive constructs, and beyond a few studies of individuals selected for high substance use, the literature contains virtually no research on this topic with other adults at risk for HIV infection, such as men who have sex with men (MSM). Purpose: This study tested whether EF was associated with condomless anal intercourse (CAI) among MSM...

BACKGROUND: Inclusion of people with intellectual disability (ID) in higher postsecondary academic education is on the rise. However, there are no scientific criteria for determining the eligibility for full inclusion of students with ID in university courses. This study focuses on two models of academic inclusion for students with ID: (a) separate adapted enrichment model: students with ID study in separate enrichment courses adapted to their level; (b) full inclusion model: students with ID are included in undergraduate courses, receive academic credits and are expected to accumulate the amount of credits for a B...

Improving accuracy in genetic studies would greatly accelerate understanding the genetic basis of complex diseases. One approach to achieve such an improvement for risk variants identified by the genome wide association study (GWAS) approach is to incorporate previously known biology when screening variants across the genome. We developed a simple approach for improving the prioritization of candidate disease genes that incorporates a network diffusion of scores from known disease genes using a protein network and a novel integration with GWAS risk scores, and tested this approach on a large Alzheimer disease (AD) GWAS dataset...

PURPOSE: A statistical method called "Magnitude-Based Inference" (MBI) has gained a following in the sports science literature, despite concerns voiced by statisticians. Its proponents have claimed that MBI exhibits superior Type I and Type II error rates compared with standard null hypothesis testing for most cases. I have performed a re-analysis to evaluate this claim. METHODS: Using simulation code provided by MBI's proponents, I estimated Type I and Type II error rates for clinical and non-clinical MBI for a range of effect sizes, sample sizes, and smallest important effects...
