Abstract:

In the tropics, cattle are majorly dependent on natural pastures growing on poor soils and as a result prone to trace element deficiencies. This work investigated several aspects of trace element nutri¬tion in zebu (Bos indicus) cattle, the most widely used cattle type in the tropics. Through several trials conducted at the Gilgel Gibe catchment, Ethiopia, we aimed to study factors influencing the flow of trace elements from soil to plant and grazing zebu cattle, and to investigate the impact of trace element status on health, production and trace elements in animal products. Overall, trace el

Abstract:

Biological trace elements are needed in small quantities but are used by all living organisms. A growing list of trace element-dependent proteins and trace element utilization pathways highlights the importance of these elements for life. In this minireview, we focus on recent advances in comparative genomics of trace elements and explore the evolutionary dynamics of the dependence of user proteins on these elements. Many zinc protein families evolved representatives that lack this metal, whereas selenocysteine in proteins is dynamically exchanged with cysteine. Several other elements, such as

Abstract:

Models that describe the trace element status formation in the human organism are essential for a correction of micromineral (trace elements) deficiency. A direct trace element retention assessment in the body is difficult due to the many internal mechanisms. The trace element retention is determined by the amount and the ratio of incoming and excreted substance. So, the concentration of trace elements in drinking water characterizes the intake, whereas the element concentration in urine characterizes the excretion. This system can be interpreted as three interrelated elements that are in equi

Understanding the ecology and evolution of migratory animals requires information on how populations are geographically linked between periods of the annual cycle. To examine whether trace elements could be used to track migratory birds, we analyzed concentrations of 42 trace elements in feathers of western sandpipers ( Calidris mauri (Cabanis, 1857)) that were grown at five different wintering sites ranging from San Francisco Bay (USA) to the Bay of Panama.

Six vascular bundles lie in two rows of three in the rachilla at the base of the fertile floret. Each bundle relates to a lemma or palea trace. As the rachilla bundles become traces they also produce sieve elements that interconnect to form the lower layer of the sieve-element plexus. Lodicule traces join the anterior of this lower plexus. Only the tracheary elements from the rachilla bundle related to the lemma's median trace rise higher in the rachilla, and these merge into a system of anomalous tracheary elements (xylem discontinuity) that rises toward the ovule.

Abstract:

The concentrations of trace elements in carbonate biominerals can provide critical proxy records of past chemical and physical environmental conditions. However, the concentrations of these elements within biominerals are influenced by the diverse biological processes that govern mineralisation. This allows us to use the trace element content of biominerals grown under known conditions to infer the biological, physical, and dynamical processes that are involved in biomineralisation mechanisms. Here we introduce how key biomineralisation mechanisms can influence trace element incorporation, and

Abstract:

Background: Oral Submucous Fibrosis (OSF) is a chronic, progressive condition characterized by fibrosis and restriction of oral mucosal tissues. It is primarily associated with areca nut chewing, which is prevalent in many parts of Asia. Imbalances in trace elements, such as zinc, copper, iron, and selenium, may influence the pathogenesis and severity of OSF. Objectives: To investigate the correlation between trace element imbalances and the severity of OSF in a Pakistani population, focusing on zinc, copper, iron, and selenium levels. Study Design & Setting: This study employed a cross-se

Abstract:

This paper summarizes speciation results in human milk samples. Information is presented about why these elements were speciated, which techniques were applied, and which speciation results were gained in human milk. We focus on a few selected elements, such as Zn, Se, I, and Mn. Each of these elements is regarded as an "essential" element and of specific importance for newborns. At the end of each element section, we attempt to extract the overall speciation information from the different literature sources. In short, for Zn it can be concluded that this element is bound predominantly to low-

Abstract:

BACKGROUND: Oxidative stress and trace elements in erythrocytes are linked to impaired nitric oxide that can lead to endothelial dysfunction in preeclampsia patients. The morphology of erythrocytes could also be affected by oxidative stress and trace elements. While the relationships between erythrocyte index, superoxide dismutase (SOD) activity, and oxidative stress in preeclampsia have been well established, less attention has been given to the erythrocyte trace elements and their role in disease progression. This study was performed to examine the erythrocyte trace element profile in women

Research highlights: this article refers to the deep storage of trace elements as a result of the podzolization process under different types of vegetation cover. This is also an attempt to trace differentiation in the distribution of trace elements in mountain soils under the podzolization process. Background and objectives: we focused on estimating whether the podzolization process of soils under various vegetation covers led to the deep storage of trace elements in the subsoil. Furthermore, the potential contamination of studied soils with trace elements using pollution indices was assessed

Unlike the commonly used methods for comparing the content of individual elements and groups of elements, this method, based on the use of the entire set of available trace element data, provides more robust results. The factual basis of the analysis is a database compiled of a large number of analyzes by different authors and including trace e

Abstract. The aim of this work was to study the role of the seagrass Posidonia oceanica on the cycling of a wide set of trace elements (Ag, As, Ba, Bi, Cd, Co, Cr, Cs, Cu, Fe, Ga, Li, Mn, Ni, Pb, Rb, Sr, Tl, V and Zn). We measured the concentration of these trace elements in the different compartments of P. oceanica (leaves, rhizomes, roots and epibiota) in a non-polluted seagrass meadow representative of the Mediterranean and calculated the annual budget from a mass balance. We provide novel data on accumulation dynamics of many trace elements in P. oceanica compartments and demonstrate that

Maintaining the homeostasis balance of trace elements is crucial for the health of organisms. Human health is threatened by diseases caused by a lack of trace elements. Saccharomyces cerevisiae has a wide and close relationship with human daily life and industrial applications. It can not only be used as fermentation products and single-cell proteins, but also as a trace elements supplement that is widely used in food, feed, and medicine. Trace-element-enriched yeast, viz., chromium-, iron-, zinc-, and selenium-enriched yeast, as an impactful microelements supplement, is more efficient, more e

Abstract:

To investigate process behaviour and process disturbances in anaerobic digestion (AD) plants, samples of more than 1500 main digesters were taken and concentrations of macro- and micronutrients as well as volatile fatty acids were analyzed. Out of these samples, 600 digesters using energy crops only and 80 digesters using waste substrates were selected to compare the chemical composition as a result of different substrate feeding. High variations in element concentrations were found in both groups. In 60 plants with low micronutrient levels, trace elements were added and process changes were o
