Use of Lipidic Extracts in the Development of Healthier Pastry Products with Reduced Fat Contents.

Pastry products constitute a significant segment of the food market. However, the high amount of fat used in their production poses a challenge when competing for the attention of modern consumers, who are more conscious of the health problems associated with the consumption of high-fat products. With this in mind, the main objective of this study is the reduction of the total fat and saturated fat contents of two bakery products, brioche-type bread and rice cake, by partial substitution of the main fat source with lipid extracts obtained through non-thermal high-pressure extraction (HPE).

Guardians' perceptions of the benefits of dogs in family dynamics during the pandemic.

During the pandemic, there were a lot of lockdowns that brought changes to the population's daily routine, reducing social interactions, changing work and study methods, isolating the family at their home, which brought changes to family dynamics. These changes sparked the interest of nursing students in carrying out a research study. Starting from the question: What is the role of the dog in the family dynamics in times of pandemic? and the objective: identify the guardians' perceptions about the role of the dog in the family dynamics in a period of confinement, a qualitative, exploratory, and descriptive study was carried out, collecting data through a focus group with six guardians from different families.

Extraction of Antioxidants from Brown Macroalgae .

In this study, different extraction methods and conditions were used for the extraction of antioxidants from brown macroalgae . The extraction methodologies used were ultrasound-assisted extraction (ultrasonic bath and ultrasonic probe), extraction with a vortex, extraction with an Ultra-Turrax homogenizer, and high-pressure-assisted extraction. The extracts were analyzed for their total phenolic content (TPC) and their antioxidant activity, and evaluated through the 2,2-difenil-1-picrilhidrazil (DPPH) free radical scavenging method and ferric reducing antioxidant power (FRAP) assay.

Inhibition of TGF-β signaling enables long-term proliferation of mouse primary epithelial stem/progenitor cells of the tympanic membrane and the middle ear mucosa.

The surface of the middle ear is composed of the tympanic membrane (TM) and the middle ear mucosa (MEM). A number of diseases and conditions such as otitis media, middle ear cholesteatoma, and perforation of the TM have been reported to cause dysfunction of the middle ear, ultimately leading to high-frequency hearing loss. Despite its importance in repairing the damaged tissues, the stem/progenitor cells of the TM and the MEM epithelia remains largely uncharacterized due, in part, to the lack of an optimal methodology to expand and maintain stem/progenitor cells long-term.

Seasonal study of the nutritional composition of unexploited and low commercial value fish species from the Portuguese coast.

Target species diversification is essential for fisheries sustainability and fish market revitalization. Fish discards are a widely recognized problem resulting from fisheries worldwide, and are of major concern for all sector players, from administrations, to fishermen, and scientists. However, non-target species are seldom studied, and information on nutritional profiles and seasonal changes in nutritional properties is generally lacking.

Annual variations in the mineral element content of five fish species from the Portuguese coast.

The most consumed fish species in Portugal do not correspond to the most caught fish species on the Portuguese coast. From the point of view of ocean sustainability and economics, it is important to study unexploited or underexploited fish species that have the potential to be introduced into the food market. This potential can be reflected by their nutritional value, where mineral elements are often overlooked despite their importance in human health.

Fabry Disease: A Atypical Presentation.

Fabry Disease (FD) is a rare X-linked recessive disease caused by mutations in the GLA gene that lead to a decrease or lack of activity of the enzyme alpha galactosyl A. This lysosomal storage disorder results in progressive damage and dysfunction of several organs and, depending on the type of mutation and gender of the patient, and it may have different manifestations. As FD is a multisystem disease with a progressive character and varying severity, the diagnosis can be challenging, especially when it comes to non-classical forms.

Adding Value to Bycatch Fish Species Captured in the Portuguese Coast-Development of New Food Products.

We live in a world of limited biological resources and ecosystems, which are essential to feed people. Consequently, diversifying target species and considering full exploitation are essential for fishery sustainability. The present study focuses on the valorization of three low commercial value fish species (blue jack mackerel, ; black seabream, ; and piper gurnard, ) and of two unexploited species (comber, and boarfish, ) through the development of marine-based food products with added value.

Seasonal Sensory Evaluation of Low Commercial Value or Unexploited Fish Species from the Portuguese Coast.

Overfishing is increasing over time, and according to FAO (Food and Agriculture Organization), about one third of the world's fish stocks are now overfished. Thus, diversifying the target species is essential for fisheries sustainability contributing to improve resource-efficient processes. Non-target species can be valuable resources for the development of new food products.

Quality Assessment of Chilled and Frozen Fish-Mini Review.

Fish is a very perishable food and therefore several storage strategies need to be employed to increase its shelf-life, guaranteeing its safety and quality from catch to consumption. Despite the advances in modern fish storage technologies, chilling and freezing are still the most common preservation methods used onboard. The present review aims to summarize strategies to increase the shelf-life of fresh (chilled) and frozen fish, as whole, gutted, or fillet, involving the assessment of different traditional cooling and freezing conditions of different fish species caught in different locations.

The Simplest Protocol for Rapid and Long-Term Culture of Primary Epidermal Keratinocytes from Human and Mouse.

Although mouse models have been used as an essential tool for studying the physiology and diseases of the skin, propagation of mouse primary epidermal keratinocytes remains challenging. In this chapter, we introduce the simplest, at least to our knowledge, protocol that enables long-term expansion of p63 mouse epidermal keratinocytes in low Ca media without the need of progenitor cell-purification steps or support by a feeder cell layer. Pharmacological inhibition of TGF-β signaling in crude preparations of mouse epidermis robustly increases proliferative capacity of p63 epidermal progenitor cells, while preserving their ability to differentiate.

Long-Term Expansion of Mouse Primary Epidermal Keratinocytes Using a TGF-β Signaling Inhibitor.

Mouse models have been used to study the physiology and pathogenesis of the skin. However, propagation of mouse primary epidermal keratinocytes remains challenging. In this chapter, we introduce a newly developed protocol that enables long-term expansion of p63 mouse epidermal keratinocytes in low-Ca media without the need of progenitor cell purification steps or support by a feeder cell layer.

Promotion of Human Epidermal Keratinocyte Expansion in Feeder Cell Co-culture.

Co-culture of human epidermal keratinocytes with mouse 3T3-J2 feeder cells, developed by Green and colleagues, has been used worldwide to generate skin autografts since the early 1980s. In addition, co-culture with 3T3-J2 cells has served as a fundamental tool in skin stem cell biology as it allows the evaluation of self-renewal capacity of epidermal stem cells. This chapter describes a recent improvement in the Green method to promote further the expansion of human epidermal keratinocytes utilizing a small-molecule inhibitor of TGF-β signaling.

Inhibition of TGF-β signaling supports high proliferative potential of diverse p63 mouse epithelial progenitor cells in vitro.

Mouse models have been used to provide primary cells to study physiology and pathogenesis of epithelia. However, highly efficient simple approaches to propagate mouse primary epithelial cells remain challenging. Here, we show that pharmacological inhibition of TGF-β signaling enables long-term expansion of p63 epithelial progenitor cells in low Ca media without the need of progenitor cell-purification steps or support by a feeder cell layer.

Inhibition of TGF-β signaling promotes expansion of human epidermal keratinocytes in feeder cell co-culture.

Cultured epidermal autografts have been used worldwide since 1981 for patients with extensive third-degree burn wounds and limited skin donor sites. Despite significant progress in techniques toward improving clinical outcome of skin grafts, the long in vitro preparation time of cultured autografts has remained a major factor limiting its widespread use. Here, we show that pharmacological inhibition of TGF-β signaling promotes the expansion of human epidermal keratinocytes (HEKs) with high proliferative potential in co-cultures with both murine 3T3-J2 cells and human feeder cells, including dermal fibroblasts and preadipocytes.

Effect of Heavy Metals in Plants of the Genus Brassica.

Several species from the Brassica genus are very important agricultural crops in different parts of the world and are also known to be heavy metal accumulators. There have been a large number of studies regarding the tolerance, uptake and defense mechanism in several of these species, notably Brassica juncea and B. napus, against the stress induced by heavy metals.

Optimal isolation and xeno-free culture conditions for limbal stem cell function.

Purpose: To preserve limbal stem cell (LSC) function in vitro with xenobiotic-free culture conditions.

Methods: Limbal epithelial cells were isolated from 139 donors using 15 variations of three dissociation solutions. All culture conditions were compared to the baseline condition of murine 3T3-J3 feeders with xenobiotic (Xeno) keratinocyte growth medium at 20% O2.

Optimization of direct fibroblast reprogramming to cardiomyocytes using calcium activity as a functional measure of success.

Direct conversion of fibroblasts to induced cardiomyocytes (iCMs) has great potential for regenerative medicine. Recent publications have reported significant progress, but the evaluation of reprogramming has relied upon non-functional measures such as flow cytometry for cardiomyocyte markers or GFP expression driven by a cardiomyocyte-specific promoter. The issue is one of practicality: the most stringent measures - electrophysiology to detect cell excitation and the presence of spontaneously contracting myocytes - are not readily quantifiable in the large numbers of cells screened in reprogramming experiments.

Effects of sitagliptin treatment on dysmetabolism, inflammation, and oxidative stress in an animal model of type 2 diabetes (ZDF rat).

The purpose of this paper is to evaluate the chronic effect of sitagliptin on metabolic profile, inflammation, and redox status in the Zucker Diabetic Fatty (ZDF) rat, an animal model of obese type 2 diabetes. Diabetic and obese ZDF (fa/fa) rats and their controls (ZDF +/+) were treated during 6 weeks with vehicle (control) and sitagliptin (10 mg/kg/bw). Glucose, HbA1c, insulin, Total-c, TGs, IL-1beta, TNF-alpha, CRPhs, and adiponectin were assessed in serum and MDA and TAS in serum, pancreas, and heart.

p63 Is essential for the proliferative potential of stem cells in stratified epithelia.

The distinguishing feature of adult stem cells is their extraordinary capacity to divide prior to the onset of senescence. While stratified epithelia such as skin, prostate, and breast are highly regenerative and account disproportionately for human cancers, genes essential for the proliferative capacity of their stem cells remain unknown. Here we analyze p63, a gene whose deletion in mice results in the catastrophic loss of all stratified epithelia.
