How long dose zinc supplimention need to treat zinc deficincy?
4 answers
Zinc supplementation duration for treating zinc deficiency varies based on the specific condition. In cases of transient zinc deficiency in breastfed preterm infants, a 15-week-old baby girl showed complete healing of zinc deficiency-related lesions after a two-week trial of oral zinc supplementation at 3 mg zinc gluconate/kg body weight/day, with treatment withdrawal at six months of age. However, in a study evaluating different doses and frequencies of zinc supplementation in children aged 9-11 months, the interventions over a 24-week period did not effectively reduce diarrhea incidence, indicating that longer durations or different dosages may be needed for zinc supplementation to treat diarrhea effectively. Therefore, the duration of zinc supplementation for treating zinc deficiency can range from a few weeks to several months, depending on the specific circumstances and conditions being addressed.
Is zinc defficency assosiated with hight blood pressure?
4 answers
The association between zinc deficiency and high blood pressure is supported by a body of research that suggests a complex relationship influenced by dietary intake, serum levels, and the presence of chronic conditions. Zinc deficiency has been identified as a potential hidden driver in the cycle of chronic kidney disease (CKD) and hypertension, with evidence suggesting that urinary zinc wasting can fuel zinc deficiency in CKD, which in turn may accelerate the progression of hypertension and kidney damage. Studies assessing healthy subjects have also explored the link between zinc deficiency and prehypertension, indicating a broader relevance of zinc status in blood pressure regulation beyond those with chronic conditions. Research further indicates that zinc deficiency alone can exacerbate hypertension, highlighting the importance of zinc in blood pressure regulation. In children and adolescents, dietary intake of zinc has been associated with the risk of high blood pressure, suggesting that the impact of zinc on blood pressure may begin early in life. A systematic review and meta-analysis of randomized clinical trials found that zinc supplementation significantly reduced systolic blood pressure in adults, although it had no significant effect on diastolic blood pressure. This finding is supported by a study showing lower serum zinc levels in hypertensive subjects compared to non-hypertensive subjects. However, the relationship between zinc, copper, and hypertension appears to be complex, with some studies not finding an independent association between zinc and hypertension in adults. In obese Korean women, dietary zinc intake was inversely associated with systolic blood pressure, suggesting that dietary zinc may be an independent risk factor for elevated systolic blood pressure in specific populations. The joint effect of multi-metal co-exposure, including zinc, on blood pressure has also been investigated, revealing a positive association between zinc and blood pressure in the context of multi-metal exposure. Lastly, a large study within the Iranian population found no association between serum zinc levels and systolic blood pressure, but a significant association was observed with diastolic blood pressure in certain quartiles. In summary, the evidence suggests that zinc deficiency is associated with high blood pressure, although the relationship can be influenced by factors such as dietary intake, serum levels, the presence of other metals, and specific population characteristics.
How does the biotin function in skin and scalp?

How do microbial communities respond to plastic and zinc as substitutes for tire abrasion?
4 answers
Microbial communities respond differently to plastic and zinc as substitutes for tire abrasion. When exposed to environmentally realistic concentrations of plastic and zinc, microbial communities showed generally unchanged diversity with zinc causing a change in community structure. In coastal sediments, pristine and aged tire wear particles (TWPs) altered bacterial community structures, affecting nitrogen metabolism, with aged TWPs being more toxic due to changes in surface characteristics. Microplastics in aquatic environments can change the structure and function of attached bacterial communities, with PET and PVC microplastics showing different effects on bacterial diversity and function, influenced by water depth. In soil-plant systems, microplastics and ZnO NPs influenced maize growth and arbuscular mycorrhizal fungal communities, impacting plant fitness and soil microbial diversity.
What are the potential negative effects of excessive intake of vitamin C?
5 answers
Excessive intake of vitamin C can lead to various negative effects. High doses of vitamin C may not prevent Covid-19 infection and can be harmful, with toxic effects observed for Vitamin D and zinc as well. In terms of dental health, chewable vitamin C tablets can cause acid erosion of enamel, resulting in significant tooth wear if consumed excessively.

Therefore, it is crucial for individuals to be aware of the potential harmful effects of excessive vitamin C intake on overall health, dental health, and metabolic health.
What is zinc excretion in kidney?
4 answers
Zinc excretion in the kidney is a complex process influenced by various physiological and pathological conditions. Studies have shown that urinary zinc levels can be elevated in several disorders, including solid tumors, hematologic malignancies, autoimmune rheumatic disorders, bacterial infections, diabetes mellitus, and nephropathy, suggesting a significant relationship between urinary zinc loss and the acute phase response. Chronic kidney disease (CKD) patients exhibit lower circulating zinc levels and higher urinary zinc excretion compared to individuals without CKD, indicating that zinc deficiency in CKD is not compensated by reduced renal zinc excretion. In diabetic patients, particularly those with insulin-dependent diabetes mellitus (IDDM), an increase in urinary zinc excretion and renal zinc clearance has been observed, suggesting that insulin may play a role in inhibiting urinary zinc excretion. The influence of amino acids on zinc excretion has been demonstrated in animal studies, where infusions of cysteine significantly increased urinary zinc excretion, indicating that plasma and urine concentrations of certain amino acids are major determinants of urinary zinc excretion. Diuretic treatment, particularly with thiazides, has been shown to increase urinary zinc excretion, highlighting the impact of medication on zinc loss. In Drosophila, a model organism for studying zinc homeostasis, specific zinc transporters have been identified in the Malpighian tubules (analogous to mammalian kidneys) that play critical roles in zinc excretion and reabsorption, suggesting a highly regulated process of zinc handling in the kidney. Furthermore, the immune system's activation, as indicated by elevated urinary neopterin excretion in various disorders, has been correlated with increased urine zinc output, suggesting a protective role of zinc in renal pathology. However, patients with urolithiasis have shown lower urinary zinc excretion, indicating that zinc excretion patterns can vary significantly across different renal pathologies. Zinc deficiency has been associated with the development and progression of CKD and its complications, emphasizing the importance of zinc homeostasis in kidney health. Collectively, these studies underscore the multifaceted nature of zinc excretion in the kidney, influenced by disease states, nutritional status, hormonal regulation, and possibly genetic factors related to zinc transporters.
