Article Synopsis
  • Sosnowski hogweed is an invasive weed in Eastern-Middle Europe that poses risks to human health and the environment, and traditional control methods are limited in effectiveness.
  • The study investigated using electromagnetic radiation (microwaves) to control the weed by testing various microwave treatment durations (2.5 to 15 minutes) and assessing the impact on both the hogweed and the surrounding soil.
  • Results showed that microwave treatment significantly reduced hogweed root growth, with treated soils categorized as non-toxic or low-toxic, suggesting microwave treatment could be an environmentally friendly control method, though further research is required.

Background: To better understand the molecular mechanism responsible for the therapeutic potential of vitamin D, we conducted an analysis of the liver transcriptomes of adult female rats.

Methods: Adult female rats (n = 18) were divided into three groups, receiving different doses of vitamin D: group I, 0; group II, 1000 U/kg; and group III, 5000 U/kg. Growth, body weight, the weight of main organs, blood haematological and biochemical parameters were evaluated.

A proper formulation is crucial to improve the herbicidal effects of essential oils and their selectivity. In this study, we investigated the physicochemical properties of bio-based nanoemulsions (CNs) containing several concentrations of caraway (Carum carvi) essential oil stabilized with Eco Tween 80, as a surfactant, maintaining 1:1 proportions. Detailed physicochemical characteristics of the CNs revealed that their properties were most desired at 2% of the oil and surfactant, i.

Maintaining an appropriate concentration of vitamin D is essential for the proper functioning of the body, regardless of age. Nowadays, there are more and more indications that vitamin D supplementation at higher than standard doses may show protective and therapeutic effects. Our study identified differences in the body's response to long-term supplementation with cholecalciferol at an increased dose.

Mare endometrial fibrosis (endometrosis), is one of the main causes of equine infertility. Despite the high prevalence, both ethology, pathogenesis and the nature of its progression remain poorly understood. Recent studies have shown that microRNAs (miRNAs) are important regulators in multiple cellular processes and functions under physiological and pathological circumstances.

Knockout of TRDMT1 methyltransferase affects DNA methylome in glioblastoma cells.

J Neurooncol

May 2023

Department of Biotechnology, Institute of Biology and Biotechnology, College of Nature Sciences, University of Rzeszow, Pigonia 1, 35-310, Rzeszow, Poland.

Purpose: We have previously shown that TRDMT1 methyltransferase is a regulator of chemotherapy-associated responses in glioblastoma cells. Despite the fact that glioblastoma, a common and malignant brain tumor, is widely characterized in terms of genetic and epigenetic markers, there are no data on TRDMT1-related changes in 5-methylcytosine pools in the genome. In the present study, the effect of TRDMT1 gene knockout (KO) on DNA methylome was analyzed.

Due to climate change, heat stress is a growing problem for the dairy industry. Based on this, annual economic losses in the dairy sector are verified mainly on a large scale. Despite several publications on thermal stress in lactating dairy cows in confinement systems, there need to be published reviews addressing this issue systematically.

Trees can be used as archives of changes in the environment. In this paper, we present the results of the analysis of the impact of water stress and increase in air temperature on BAI and carbon stable isotopic composition and water use efficiency of pine. Dendrochronological methods together with mass spectrometry techniques give a possibility to conduct a detailed investigation of pine growing in four industrial forests in Silesia (Poland).

Essential oils exhibit strong antimicrobial effects that can serve as a substitute for synthetic pesticides. However, many reports mention the use of essential oils in protecting above-ground plant organs and storing raw materials and seeds, but only a few address the effects of treatments on soil microbiota. Regarding this, it is necessary to find a solution that will prevent the rapid degradation of oils in soil and extend the period of their action on the soil microbiota.

Variation of the bark depends on tree age, origin, geographic location, or site conditions like temperature and water availability. Most of these variables are characterized by very high variability but above of all are also affected by climate changes. This requires the construction of improved bark thickness models that take this complexity into account.

Salinity is the primary environmental stress that adversely affects plants' growth and productivity in many areas of the world. Published research validated the role of aspartic acid in improving plant tolerance against salinity stress. Therefore, in the present work, factorial pot trials in a completely randomized design were conducted to examine the potential role of exogenous application of aspartic acid (Asp) in increasing the tolerance of wheat ( L.

The highly infectious coronavirus disease (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is a new coronavirus that has been spreading since late 2019 and has caused millions of deaths worldwide. COVID-19 continues to spread rapidly worldwide despite high vaccination coverage; therefore, it is crucial to focus on prevention. Most patients experience only mild symptoms of COVID-19.

Ex vivo expansion of chondrocytes in monolayer (ML) culture for therapeutic purposes is burdened with difficulties related to the loss of cartilaginous phenotype. Epigenetic mechanisms responsible for regulation of gene expression are believed to underlie chondrocyte dedifferentiation. We have inspected the relevance of DNA methylation alterations for passage-related differential expression of NFATC1 gene involved in hard connective tissue turnover and development, NADSYN1 influencing redox metabolism, and JAK3 - an important driver of inflammation.

Microencapsulated Caraway Essential Oil Affects Initial Growth of Maize Cultivars.

Molecules

August 2021

Department of Agroecology and Crop Production, Faculty of Agriculture and Economics, The University of Agriculture in Krakow, Mickiewicza 21, 31-120 Kraków, Poland.

Article Synopsis
  • Caraway essential oil, specifically maltodextrin-coated caraway oil (MCEO), is being researched as a potential botanical herbicide that could impact maize growth.
  • A pot experiment tested various doses of MCEO on four maize cultivars, revealing significant delays and impairments in maize emergence and development at doses as low as 44 g m.
  • The study found that two maize cultivars, Rywal and Pomerania, were less affected by MCEO than the other two cultivars, Kurant and Podole.

MicroRNAs (miRNAs) are recognized as gene expression regulators, indirectly orchestrating a plethora of biological processes. Single nucleotide polymorphism (SNP), one of the most common genetic variations in the genome, is established to affect miRNA functioning and influence complex traits and diseases. SNPs in miRNAs have also been associated with important production traits in livestock.

The maintenance of homeostasis of the intestinal epithelium depends on the complex process of epithelial cells differentiation, which repeatedly continues throughout the entire life. Many studies suggest, that cellular differentiation is regulated by glycosylation, or at least that changes of the latter are the hallmark of the process. The detailed description and understanding of this relationship are important in the context of gastrointestinal tract disease, including cancer.

Horse musculature has been shaped through evolution by environmental and human factors, which has resulted in several extraordinary adaptations to physical effort. Skeletal muscle plasticity results from the response to mechanical stimulation causing hypertrophy, where sarcomeres increase the muscle's cross-sectional area under the influence of contractile forces. The aim of the present study was the evaluation of transcript abundance of the telethonin () gene, which is a part of the sarcomere macromolecular mechanosensory complex in the gluteus medius muscle, and the whole blood of Arabian horses during flat race training.

The ACTN3 gene codes for α-actinin-3, a protein localized in the Z-line in the skeletal muscle. Actinin-3 is critical in anchoring the myofibrillar actin filaments and plays a key role in muscle contraction. ACTN3 (α-actinin-3) cross-links glycogen phosphorylase (GP), which is the key enzyme catalysing glycogen metabolism.
