The redox homeostasis and photosynthetic pigments changes vary with Tetranychus ludeni infestation, with longer-cycle genotypes showing greater tolerance and efficiency in antioxidant defense. Infestations of Tetranychus ludeni Zacher (Tetranychidae) have been frequently observed in soybean plants. In this context, understanding the oscillation of redox homeostasis is crucial for detecting and assessing the stress levels caused in the plants by these organisms.

Prev Vet Med

December 2024

Division of Veterinary Epidemiology and Economics, Institute of Veterinary Medicine, Warsaw University of Life Sciences-SGGW, Nowoursynowska 159c, Warsaw 02-776, Poland. Electronic address:

Caprine arthritis-encephalitis (CAE) is a progressive disease of goats caused by small ruminant lentivirus (SRLV) and is considered as one of the most important threats for goat farming in developed countries. The disease prevalence has never been investigated in the Lithuanian goat population. Therefore, a descriptive cross-sectional study was carried out in 2021-2022 to determine if SRLV infection was present in the Lithuanian goat population and, in the case of a positive result, to estimate the true herd-level prevalence of SRLV infection and specify genotypes and subtypes of SRLV responsible for the infection.

Background/objectives: Among the most important challenges associated with the gluten-free diet are the high costs and limited availability of gluten-free products, accompanied by the lower nutritional value of gluten-free products. The aim of the presented study was to assess gluten-free products' availability and satisfaction in a Polish population of coeliac-disease patients and their caregivers.

Methods: The study was conducted in a population of Polish female coeliac-disease patients and female family members/relatives of patients diagnosed with coeliac disease, being members of the Polish Coeliac Society and purchasing gluten-free products.

The potato is the most important non-cereal food crop, and thus improving potato growth and yield is the focus of agricultural researchers and practitioners worldwide. Several studies reported beneficial effects of silicon (Si) fertilization on potato performance, although plant species from the family Solanaceae are generally considered to be non-Si-accumulating. We used results from two field experiments in the temperate zone to gain insight into silica accumulation in potato plants, as well as corresponding long-term potato yield performance.

Background: Dietary composition is one of the factors influencing the acid-base balance of the body by providing acid or base precursors. One of the methods for assessing the acid-forming potential of a diet is to calculate its potential renal acid load (PRAL). The aim of this study was to identify the sociodemographic, lifestyle, and health factors related to the PRAL.

Influence of Heat Treatment and Lactic Acid Fermentation on the Physical and Chemical Properties of Pumpkin Juice.

Molecules

September 2024

Department of Gastronomy Science and Functional Foods, Faculty of Food Science and Nutrition, Poznan University of Life Sciences, Wojska Polskiego 31, 60-624 Poznan, Poland.

Article Synopsis
  • - Pumpkin is a nutritious fruit that is often turned into juice to minimize waste due to its perishability; this study focused on fermenting pumpkin juice using various lactic acid bacteria (LAB) strains.
  • - Heat treatment before fermentation showed minimal effects on most components except for a decrease in carotenoid and polyphenol levels; fermentation consistently increased acidity and decreased pH without significant differences among LAB strains.
  • - The study confirms that certain LAB strains are effective for fermenting pumpkin juice, emphasizing the importance of thermal processing to enhance shelf life, nutritional value, and safety in the food industry.

Objectives: Genetic characterization of the antibiotic resistance determinants and associated mobile genetic elements (MGEs) among Streptococcus pyogenes [Group A streptococci (GAS)] clinical isolates of an M77 serotype collected in Poland between 2003 and 2017.

Methods: The genomes of 136 M77 GAS isolates were sequenced using Illumina, and selected with long-read approach (Oxford Nanopore). Whole genome sequences were analyzed to determine the presence of macrolide resistance determinants, and their genetic context.

The purpose of this case report is to present a poorly differentiated sarcoma in a pet rat. A veterinarian detected a small-sized nodular lesion in the ventral region of the neck during a follow-up visit related to another ailment. The anatomical structures found in the neck region in the rat and the differential diagnosis when deformities are palpated in this body part are discussed in detail.

Introduction And Objective: Dietary variety (DV) is recognized as a key indicator of diet quality. It is based on the premise that eating a wide variety of foods ensures an adequate intake of essential nutrients which, in turn, leads to better diet quality. The aim of the study is to examine the relationships between DV, diet quality and selected anthropometric parameters in older adults.

Coniferous Bark as Filler for Polylactic Acid-Based Biocomposites.

Polymers (Basel)

September 2024

Institute of Wood Sciences and Furniture, Warsaw University of Life Sciences-SGGW, 159 Nowoursynowska St., 02-776 Warsaw, Poland.

Article Synopsis
  • The study investigates coniferous bark as a potential filler for wood-polymer composites (WPCs) and its effects on important properties like strength and water resistance.
  • Six types of bark-PLA composites were created, varied by filler amounts and particle sizes, alongside similar composites made from sawdust for comparison.
  • Results showed that bark-filled composites had better water resistance but lower strength compared to sawdust composites, with filler content being the most significant factor affecting properties.

Assessment of Changes in Selected Features of Pine and Birch Wood after Impregnation with Graphene Oxide.

Materials (Basel)

September 2024

Institute of Wood Sciences and Furniture, Department of Technology and Entrepreneurship in Wood Industry, Warsaw University of Life Sciences-SGGW, 159 Nowoursynowska St., 02-776 Warsaw, Poland.

In this work, pine and birch wood were modified by graphene oxide using a single vacuum impregnation method. The research results indicate that the impregnation of wood with graphene oxide increases the crystallinity of cellulose in both pine and birch wood, and the increase in crystallinity observed in the case of birch was more significant than in the case of pine. FT-IR analyses of pine samples impregnated with graphene oxide showed changes in intensity in the absorption bands of 400-600, 700-1500 cm, and 3200-3500 cm and a peak separation of 1102 cm, which may indicate new C-O-C connections.

The carapace morphology of tortoises is a crucial characteristic used for species identification, with features such as shell shape, roughness, and color patterns varying among species. Understanding this morphological diversity is valuable not only for taxonomic classification but also for more specialized clinical approaches. This study investigated the morphological differences in the shells of Leopard tortoises (), African spurred tortoises (), and Greek tortoises (spur-thighed tortoises; ) raised in captivity.

Article Synopsis
  • The study investigated how high hydrostatic pressure (HHP) affects inulin-soy protein hydrogels using different pressure levels and times.
  • Changes in pressure from 150 to 300 MPa improved the hydrogels' microstructure, stability, yield stress, and other properties, particularly in those with lower protein content.
  • Increasing pressure to 500 MPa did not enhance the hydrogel structure and negatively impacted the stability of those with higher soy protein isolate content.
