Acetate cellulose fibrous scaffold is suitable for cultivated fat production.

Fat is an essential component of meat which contributes to its sensory characteristics. Therefore, producing cultivated fat is essential to replicate the texture, flavor, and juiciness of conventional meat. One of the challenges in obtaining cultivated fat is that once adipocytes reach differentiation in culture, they tend to float.

Random cellulose acetate nanofibers: a breakthrough for cultivated meat production.

Overcoming the challenge of creating thick, tissue-resembling muscle constructs is paramount in the field of cultivated meat production. This study investigates the remarkable potential of random cellulose acetate nanofibers (CAN) as a transformative scaffold for muscle tissue engineering (MTE), specifically in the context of cultivated meat applications. Through a comparative analysis between random and aligned CAN, utilizing C2C12 and H9c2 myoblasts, we unveil the unparalleled capabilities of random CAN in facilitating muscle differentiation, independent of differentiation media, by exploiting the YAP/TAZ-related mechanotransduction pathway.

Identification of Potential Multitarget Compounds against Alzheimer's Disease through Pharmacophore-Based Virtual Screening.

Alzheimer's disease (AD) is a neurodegenerative disease characterized by progressive loss of cognitive functions, and it is the most prevalent type of dementia worldwide, accounting for 60 to 70% of cases. The pathogenesis of AD seems to involve three main factors: deficiency in cholinergic transmission, formation of extracellular deposits of β-amyloid peptide, and accumulation of deposits of a phosphorylated form of the TAU protein. The currently available drugs are prescribed for symptomatic treatment and present adverse effects such as hepatotoxicity, hypertension, and weight loss.

Busch-Hoffa fracture: A systematic review.

Background: Accomplish a thorough review on the existing biomechanical and clinical studies about coronal plane fractures of the distal femur.

Methods: We performed an electronic search of PubMed/MEDLINE database from April to June, 2023. The terms for the database search included "Hoffa fractures," OR "Busch-Hoffa fractures" OR "coronal plane fractures of the distal femur.

Impacts of smoking on oral health-what is the role of the dental team in smoking cessation?

Data Sources: Electronic searches were conducted on databases (PubMed, EMBASE, and Google Scholar). In addition, websites of national organisations (US Food and Drug Administration, National Cancer Institute, Centres for Disease Control and Prevention, American Dental Association, Office of Disease Prevention and Health Promotion, National Institute on Drug Abuse, Agency for Healthcare Research and Quality) were also searched.

Study Selection: To achieve the objectives of the study, systematic reviews, controlled clinical trials, and observational studies published between October 2021 and February 2022 were considered.

Correlation of the presence of acrolein with higher alcohols, glycerol, and acidity in cachaças.

Acrolein is a toxic aldehyde that can be present in various beverages, such as cachaça and other distilled spirits from sugarcane. The objective of this work was to detect and quantify acrolein in samples of cachaça produced by different processes in all regions of Brazil and to evaluate the possible routes of formation of this contaminant from the correlation with other secondary compounds present in the beverage using principal component analysis. Approximately 27.

Experimental dataset on the residual performance of fiber-reinforced cementitious composite subjected to high temperature.

The present dataset refers to the research article entitled "A multiscale investigation on the performance improvement of fiber-reinforced cementitious composites after exposure to high temperatures" [1]. Supplementary data on raw materials characterization, temperature recording, mass loss, water absorption, compressive strength, flexural behavior, pull-out response, fiber-matrix interface, and surface, microstructure and hardness of fibers are presented here. The continuous matrix was produced from cementitious grout containing Portland cement, sand, silica fume, superplasticizer, and water.

Association of urban inequality and income segregation with COVID-19 mortality in Brazil.

Socioeconomic factors have exacerbated the impact of COVID-19 worldwide. Brazil, already marked by significant economic inequalities, is one of the most affected countries, with one of the highest mortality rates. Understanding how inequality and income segregation contribute to excess mortality by COVID-19 in Brazilian cities is essential for designing public health policies to mitigate the impact of the disease.

Access to urban activities during the Covid-19 pandemic and impacts on urban mobility: The Brazilian context.

Social distancing has been adopted as a strategy to contain the advance of the pandemic until specific solutions to combat the virus are available. Many economic sectors and social activities need to continue despite the viruses, and most social distancing policies disregard individual choices, resulting in greater or lesser adherence to isolation. In this paper, we characterize the differentiation of access to essential activities within Brazilian cities during social distancing and the intention to maintain behavior changes concerning these activities in the post-pandemic period.

Cellulose acetate nanofibers loaded with crude annatto extract: Preparation, characterization, and in vivo evaluation for potential wound healing applications.

In this study we prepared annatto-loaded cellulose acetate nanofiber scaffolds and evaluated both in vitro cytotoxicity and potential for wound healing in a rat model. Annatto extract, which has been used to accelerate wound healing, was added to cellulose acetate polymer and the resulting material was used to produce nanofiber scaffolds via electrospinning. Physicochemical, and thermal evaluation of the resulting nanofiber mats showed that incorporating annatto did not significantly affect the thermal or chemical stability of the polymer.

Lactic Acid Bacteria as Delivery Vehicle for Therapeutics Applications.

Lactic acid bacteria comprise a large group of Gram-positive organisms capable of converting sugar into lactic acid. They have been studied due to their therapeutic potential on the mucosal surface. Among the species, Lactococcus lactis is considered the model bacterium and it has been explored as an important vehicle for providing therapeutic molecules and antigens in the mucosa.

Current-Mode Self-Amplified CMOS Sensor Intended for 2D Temperature Microgradients Measurement and Imaging.

This paper presents the design of a current-mode CMOS self-amplified imager operating in dark conditions, for thermal imaging, which provides an innovative solution for precision thermal contact mapping. Possible applications of this imager range from 3D CMOS integrated circuits to the study of in-vivo biological samples. It can provide a thermal map, static or dynamic, for the measurement of temperature microgradients.

Structure-Based Virtual Screening: From Classical to Artificial Intelligence.

The drug development process is a major challenge in the pharmaceutical industry since it takes a substantial amount of time and money to move through all the phases of developing of a new drug. One extensively used method to minimize the cost and time for the drug development process is computer-aided drug design (CADD). CADD allows better focusing on experiments, which can reduce the time and cost involved in researching new drugs.

Strategy for phytomanagement in an area affected by iron ore dam rupture: A study case in Minas Gerais State, Brazil.

In 2015, the Fundão tailing dam collapsed over the district of Bento Rodrigues (Mariana, Minas Gerais, Brazil) causing deaths, hundreds of homeless families and incalculable environmental degradation. Environmentally, economically and socially sustainable strategies are needed for the recovery of the affected areas. The main goal of this study was to evaluate the development, biomass production and toxic mineral elements absorption of three species of aromatic grasses (Chrysopogon zizanioides, Cymbopogon citratus and Cymbopogon winterianus).
