Chronic obstructive pulmonary disease (COPD) is a heterogeneous condition with airflow limitation and obstructive characteristics of respiratory function. In addition, musculoskeletal dysfunction and negative changes in body composition, among other comorbidities associated with this disease, result in a low quality of life. Pulmonary rehabilitation (PR), which includes physical exercise, can positively contribute to improving the clinical conditions in individuals with COPD.

Background/objectives: According to the World Health Organization, the gold standard for diagnosing COVID-19 is the Reverse Transcription Polymerase Chain Reaction (RT-PCR) test. However, to confirm the diagnosis in patients who have negative results but still show symptoms, imaging tests, especially computed tomography (CT), are used. In this study, using convolutional neural networks, we compared the following topics using manual and automatic lung segmentation methods: (1) the performance of an automatic segmentation of COVID-19 areas using two strategies for data partitioning, CT scans, and slice strategies; (2) the performance of an automatic segmentation method of COVID-19 when there was interobserver agreement between two groups of radiologists; and (3) the performance of the area affected by COVID-19.

Beyond the Myths: Brazilian Consumer Perceptions of Functional Food.

Foods

December 2024

Laboratório Multidisciplinar em Alimentos e Saúde, Faculdade de Ciências Aplicadas, Universidade Estadual de Campinas (UNICAMP), Limeira 13484-350, SP, Brazil.

The growing consumer interest in functional foods and healthy eating can unfortunately lead to the spread of misinformation and the belief in food-related myths. This study analyzed Brazilian consumers' perceptions and beliefs about facts and myths regarding functional foods, focusing on attitudes, reference groups, and sociocultural factors affecting their perception. A theoretical model was developed, incorporating constructs such as attitudes (reward, trust, necessity, safety), beliefs, and reference groups.

The growing focus on sustainable use of natural resources has brought attention to cashew nut shell liquid (CNSL), a by-product rich in anacardic acids (AAs) with potential applications in diabetes treatment. In this study, three different AAs from CNSL, monoene (15:1, AAn1), diene (15:2, AAn2), and triene (15:3, AAn3), and a mixture of the three (mix) were evaluated as -glucosidase inhibitors. The samples were characterized by combining 1D and 2D NMR spectroscopy, along with ESI-MS.

A creative approach to reducing food waste by reusing industrial cake waste can result in the development of a worldwide favorite snack. This study aimed to evaluate the potential of industrial cake wastes-basic mini cake (BMC), filled mini cake (FMC), and traditional mini cake (TMC)-as sustainable alternatives to wheat flour in producing ring-shaped cookies. After initial screening, FMC was upcycled at 10%, 15%, 20%, 30%, and 50% of wheat flour replacement for ring-shaped cookie processing.

The egg has natural barriers that prevent microbiological contamination and promote food safety. The use of non-destructive methods to obtain morphometric measurements of chicken eggs has the potential to replace traditional invasive techniques, offering greater efficiency and accuracy. This paper aims to demonstrate that estimates derived from non-invasive approaches, such as 3D computed tomography (CT) image analysis, can be comparable to conventional destructive methods.

Food waste (FW) is a common source of contamination, contaminating both soils and water bodies by releasing greenhouse gases. FW holds great potential for biofuel and bioproduct production, which can mitigate its environmental impact and become a valuable addition to the circular bioeconomy. Therefore, this work aimed to investigate the use of food waste as a substrate to produce fermentable sugars and bioethanol.

Biofilms are of great concern for the meat industry because, despite the implementation of control plans, they remain important hotspots of contamination by foodborne pathogens, highlighting the need to better understand the ecology of these microecosystems. The objective of this paper was to critically survey the recent scientific literature on microbial biofilms of importance for meat safety and quality, also pointing out the most promising methods to combat them. For this, the databases PubMed, Scopus, Science Direct, Web of Science, and Google Scholar were surveyed in a 10-year time frame (but preferably papers less than 5 years old) using selected keywords relevant for the microbiology of meats, especially considering bacteria that are tolerant to cleaning and sanitization processes.

Evidence for the Transcription of a Satellite DNA Widely Found in Frogs.

Genes (Basel)

December 2024

Laboratório de Estudos Cromossômicos, Instituto de Biologia, Universidade de Campinas, Campinas 13083-862, SP, Brazil.

Background: The satellite DNA (satDNA) PcP190 has been identified in multiple frog species from seven phylogenetically distant families within Hyloidea, indicating its broad distribution. This satDNA consists of repeats of approximately 190 bp and exhibits a highly conserved region (CR) of 120 bp, which is similar to the transcribed region of 5S ribosomal DNA (rDNA), and a hypervariable region (HR) that varies in size and nucleotide composition among and within species. Here, to improve our understanding of PcP190 satDNA, we searched for evidence of its transcription in the available transcriptomes of (Bufonidae) and (Leptodactylidae), two phylogenetically distantly related species.
