Micronutrient undernutrition during critical periods of growth has become an important health issue in developing and developed countries, particularly among pregnant women and children having an imbalanced diet. Zinc is...

The emerging field of nanophotonics initiated a dedicated study of single photon sources and optical resonators in new class of materials. One such material is zinc oxide (ZnO) that has been long considered onl...

Extreme light confinement observed in periodic photonic structures, such as the vortex singularities in momentum (k) space, has been associated with their topological nature. Consequently, by exploiting and tuning their ...

Nano- and micro-oxides are promising materials due to several interesting characteristics such as photocatalytic and antimicrobial role. In this work, zinc oxide nanorods were obtained by microwave-assisted solvothermal ...

The properties of two new lipophilic isomeric phthalocyanines 2,9(10),16(17),23(24)-tetrakis-[(2-dimethylamino)ethylsulfanyl] phthalocyaninatozinc(II) (Pc9) and 1,8(11),15(18),22(25)-tetrakis[(2- dimethylamino)ethylsulfa...

Abstract Various silicate compounds have been extensively used for scaffold fabrication via electrospinning. However, harnessing the bioactive properties of Calcium silicate (CS) and Zinc silicate (ZS) are less explored ...

ABSTRACT Zinc is a critical nutrient for all living organisms, including bacterial pathogens such as Corynebacterium diphtheriae, the causative agent of the severe human respiratory disease diphtheria. As such, zinc acqu...

Utilizaram-se 140 coelhos das raças Nova Zelândia Branco e Califórnia, com 60 dias de idade, de ambos os sexos, distribuídos em 14 tratamentos experimentais, com o objetivo de determinar a biodisponibilidade de zinco...

Zinc Selenide Nanoparticles (NPs) were fabricated by the aqueous techneque using cold plasma under atmospheric pressure with an exposure time of 3 min and a gas flow rate of 3 liters per minute. films' structural charact...

Abstract Biofortification is a sustainable approach to reduce Zn deficiency in Sub-Saharan Africa, yet the efficiency of common beans (Phaseolus vulgaris L.) in Zn uptake and translocation remain unclear. This study exam...

Minerals such as copper (Cu) and zinc (Zn) are essential trace elements with specific roles in the antioxidant defense system. They are also vital for the health and growth of dairy cattle. We hypothesised that simultane...

Cadmium (Cd) accumulation in rice poses a serious threat to food safety. While soil amendments with manganese (Mn) and zinc (Zn) can reduce Cd accumulation in rice, their distinct modes of action remain unclear, hinderin...

Abstract Heat stress is a major challenge in the poultry industry, adversely affecting birds’ physiological activity, appetite, growth rate, egg production, and egg quality. This study aimed to mitigate the negative ef...

Abstract Green composites are increasingly attracting interest due to their potential to address environmental issues by merging sustainable fillers with biodegradable polymers. The current study investigates the incorpo...

Purpose: Hypothyroidism has been shown to induce immunosuppression and both the thyroid status and immunity are affected by zinc deficiency. However, the impact of hypothyroidism on zinc metabolism and its possible relat...

ABSTRACT The objective of the present study was to evaluate the effect of feed type, pH, and Cu and Zn concentration on Cu and Zn binding with different feedstuffs after in vitro incubation in water. For this purpose, si...

Heavy metal soil contamination is one of the most serious environmental problems, considering both their persistence and progressive accumulation which makes possible the transference to other systems, and could potentia...

We previously showed that the combination of the non-nucleoside reverse transcriptase inhibitor (NNRTI) MIV-150 with zinc acetate (ZA) formulated in a carrageenan (CG; MZC) gel provided macaques significant protection ag...

Abstract Minimal hepatic encephalopathy (MHE) is a cognitive, motor, and sleep-related disorder resulting from liver impairment, often linked to elevated ammonia levels. Zinc deficiency is common in patients with cirrhos...

Abstract Plant tolerance, a significant parameter against saline conditions has become challenging and a hallmark for agriculture crops. There is an urgent need to incorporate green nanostructure approaches to cope with ...

Manganese dioxide cathodes offer high operating voltages and energy densities, showing great potential for use in aqueous zinc-ion batteries. However, their practical use has been limited by poor cycling stability caused...

The influence of the chemical composition of the electrolyte and its temperature on the process of sythesis of nanosized zinc compounds by electrolytic method using zinc electrodes was investigated. X-ray studies have be...
