Zinc and Selenium Mitigate Abiotic Stresses in Plants
Abiotic stress factors are considered a serious threat to various growth parameters of crop plants. Stressors such as drought, salinity, and heavy metals (HMs) hamper the chlorophyll content in plants, resulting in low photosynthesis, hinder the integrity of cell membranes, reduce biomass, and overall growth and development of crops which ultimately results in the sharp decline of crop yield. Under such stressful conditions, various strategies are employed to overcome hazardous effects. Application of Zinc (Zn) or Selenium (Se) in different forms is an effective way to alleviate the abiotic stresses in plants. Zn and Se play a pivotal role in enhancing the chlorophyll level to improve photosynthesis, reducing oxidative stress by limiting reactive oxygen species (ROS) production, controlling HMs absorption by plant roots and their accumulation in the plant body, maintaining homeostasis, and alleviating all the detrimental effects caused by abiotic stress factors.

Zinc and Health
Zinc is a redox-inert trace element that is second only to iron in abundance in biological systems. In cells, zinc is typically buffered and bound to metalloproteins, but it may also exist in a labile or chelatable (free ion) form. Zinc plays a critical role in prokaryotes and eukaryotes, ranging from structural to catalytic to replication to demise.

Zinc and Dog Food
Zinc is an essential trace element, required for enzymatic, structural, and regulatory functions. As body reserves are scarce, an adequate zinc status relies on proper dietary supply and efficient homeostasis. Several biomarkers have been proposed that enable the detection of poor zinc status, but more sensitive and specific ones are needed to detect marginal deficiencies. The zinc content of commercial dry dog foods has great variability, with a more frequent non-compliance with the maximum authorized limit than with the nutritional requirement. The bioavailability of dietary zinc also plays a crucial role in ensuring an adequate zinc status.

Zinc and autophagy in AMD
Zinc supplementation is reported to slow down the progression of age-related macular degeneration (AMD), but there is no general consensus on the beneficiary effect on zinc in AMD. As zinc can stimulate autophagy that is declined in AMD, it is rational to assume that it can slow down its progression. As melanosomes are the main reservoir of zinc in the retina, zinc may decrease the number of lipofuscin granules that are substrates for autophagy. The triad zinc–autophagy–AMD could explain some controversies associated with population studies on zinc supplementation in AMD as the effect of zinc on AMD may be modulated by genetic background. This aspect was not determined in many studies regarding zinc in AMD. Zinc deficiency induces several events associated with AMD pathogenesis, including increased oxidative stress, lipid peroxidation and the resulting lipofuscinogenesis. The latter requires autophagy, which is impaired. This is a vicious cycle-like reaction that may contribute to AMD progression. Promising results with zinc deficiency and supplementation in AMD patients and animal models, as well as emerging evidence of the importance of autophagy in AMD, are the rationale for future research on the role of autophagy in the role of zinc supplementation in AMD.

Zimbro
Zimbro or common juniper (Juniperus communis) is traditionally used to treat renal suppression, acute and chronic cystitis, bladder catarrh, albuminuria, leucorrhea, and amenorrhea. These uses are mainly attributed to its bioactive composition, which is very rich in phenolics, terpenoids, organic acids, alkaloids, and volatile compounds. In the last few years, several studies have analyzed the huge potential of this evergreen shrub, describing a wide range of activities with relevance in different biomedical discipline areas, namely antimicrobial potential against human pathogens and foodborne microorganisms, notorious antioxidant and anti-inflammatory activities, antidiabetic, antihypercholesterolemic and antihyperlipidemic effects, and neuroprotective action, as well as antiproliferative ability against cancer cells and the ability to activate inductive hepato-, renal- and gastroprotective mechanisms.

Zika Virus Properties
ZIKV belongs to the genus of Flavivirus in the Flaviviridae family that comprises multiple deadly human pathogens, including the dengue virus (DENV), Japanese encephalitis (JEV), the yellow fever virus (YFV), and the West Nile virus (WNV). ZIKV infection is known to result in severe manifestations including neurological complications in adults and congenital abnormalities in newborns.

Zika Virus Pathogenesis
ZIKV (Zika virus) is a mosquito-borne, positive-sense single-stranded RNA virus belonging to the family Flaviviridae (genus Flavivirus). ZIKV is further classified by homology to the Spondweni virus (SPONV) in the Spondweni viral clade or serogroup, both viruses were first characterized in Africa in 1947 and 1952, respectively.

Zika Virus in Brief
The Zika virus, a member of the Flaviviridae family, stands as a testament to the ever-evolving landscape of global health concerns in the early 21st century. In its nascent years, this virus inhabited the shadows of medical obscurity, inflicting sporadic, seemingly inconsequential bouts of mild illness primarily within the continents of Africa and Asia. Its existence remained relegated to the annals of medical journals and local health records, with little resonance in the broader global health discourse. However, this viral entity was destined for a meteoric rise to infamy, an emergence that would reverberate throughout the international community. The watershed moment transpired in 2015 when the Zika virus, once a modest player on the infectious disease stage, seized the spotlight by inciting a large-scale epidemic that unfurled across the vast expanse of the Americas. This sudden and dramatic expansion of the virus's reach thrust it into the forefront of global public health concerns, sending shockwaves through scientific, medical, and governmental circles. As we embark on this comprehensive review, it is essential to unravel the multifaceted tapestry of the Zika virus's journey. Beyond its mere identification and characterization, this exploration will delve deep into its enigmatic origins, intricate modes of transmission, the myriad impacts it has wrought upon human health, and the concerted efforts undertaken globally to wrest control from its insidious grip. This virus, once consigned to relative obscurity, has compelled the world's attention, ushering in a new era of infectious disease management and prompting a collective response from the global community. The story of the Zika virus serves as both a cautionary tale and a testament to the resilience and adaptability of pathogens in the face of a changing world.

ZIKA Virus and Male Infertility
Zika virus (ZIKV) has been reported by several groups as an important virus causing pathological damage in the male reproductive tract. ZIKV can infect and persist in testicular somatic and germ cells, as well as spermatozoa, leading to cell death and testicular atrophy. ZIKV has also been detected in semen samples from ZIKV-infected patients. This has huge implications for human reproduction. Global scientific efforts are being applied to understand the mechanisms related to arboviruses persistency, pathogenesis, and host cellular response to suggest a potential target to develop robust antiviral therapeutics and vaccines. Here, we discuss the cellular modulation of the immunologic and physiologic properties of the male reproductive tract environment caused by arboviruses infection, focusing on ZIKV. We also present an overview of the current vaccine effects and therapeutic targets against ZIKV infection that may impact the testis and male fertility.
