Product Information

The maintenance required to keep these tanks in excellent condition is minimal, making them ideal for both experienced aquarists and those just getting started with aquatic life. Borneo Fern Aquarium

Cutting your plants in this way can induce too much stress on them, especially on weakened or early developing plants, cutting too much and in the wrong places can stunt or even kill the plant. Britain had narrowly missed out on a medal over the first two days in Fukuoka, with the women's 4x100m freestyle relay team coming fourth on Sunday and Jacob Peters and Ben Proud finishing fourth and fifth respectively in the men's 50m butterfly final on Monday. If this is the case, then how do we properly anchor the plants and prevent them from just floating around the aquarium? Similar to other drugs or pollutants, MeNPs may have negative effects on reproductive organ function and development. The potential adverse effect of AuNPs on the reproductive system has been investigated by histological observations and assessment of AuNP accumulation in male or female reproductive organs, evaluation of the sperm quality and fertility of males, as well as the quantification of the sex hormones in the serum of the blood. More specifically, AuNPs can accumulate in the testes and cause the reduction of testosterone production through the downregulation of the expression of 17α-hydroxylase [ 125, 126].

You can also use elastic bands to tie down a plant, but be warned that the rubber can leach poisonous microplastics into the water, and can be devastating if swallowed by a large fish. This plant can be grown under most lighting conditions, though it needs moderate light levels to maintain its growth rate and vibrant colors. In 1597 Sir Francis Bacon said: “ ipsa scientia potestas est” (”knowledge itself is power”). Aur’a Gold Water delivered with the knowledge of its benefits, is a powerful combination.

While Pothos is not a true aquatic species, it will boost the water quality of your aquarium. Only the roots of the plant should be kept in water as they help to get rid of waste. CEN/TC 352:WI = 00352043; Guidance on the determination of aggregation and agglomeration state of nano-objects. The examination of excretion and metabolism of nanoparticles at various time points after exposure. AuNPs are known to be able to disrupt cell membrane integrity. Thus, monitoring the leakage of specific cell components such as lactate dehydrogenase assay (LDH) or adenosine tri-phosphate assay (ATP) in specific assays can be used to assess AuNPs’ cytotoxicity. When cells are damaged, there is a leakage of lactate dehydrogenase, which can be further quantitatively measured and compared to the control cells [ 74]. Cell adhesion (the ability of cells to fix a solid support) can be impaired by AuNPs, and thus can be used as a parameter to estimate their cytotoxicity. Estimation between the living/adherent and dead/detached cells can be performed using simple crystal violet staining. This dye can easily bind to the proteins and DNA only of viable cells [ 71]. It worth mentioning that in such assays, the optical properties of AuNPs and absorption ability may affect the test quantification [ 75].

Sea stories

Although a significant number of nanodrugs and nanopharmaceuticals have been approved in recent decades for a variety of indications, FDA-approved materials are heavily weighted towards polymeric and liposomal NMs. At present, there is a trend towards development of inorganic and metal nanoparticles, and indeed, AuNPS are well represented in this field. However, only a few examples of AuNPs currently are under investigation in clinical trials [ 161, 162]. According to the literature, Aurimune CYT-6091 (Cytimmune) is the first tumor-targeted nanomedicine consisting of tumor necrosis factor-α (TNF) covalently linked to pegylated colloidal gold nanoparticles [ 163, 164]. The conclusion after finishing the phase I clinical trial was that CYT-6091 targeted tumors in humans and was well tolerated at doses greater than maximum tolerated dose for native TNF. However, further clinical studies with chemotherapy combinations are planned. Among intravenous nanoparticle therapies that are not clinically approved and are currently undergoing clinical trials are AuroLase (Nanospectra Biosciences, ClinicalTrials.gov Identifier {"type":"clinical-trial","attrs":{"text":"NCT01679470","term_id":"NCT01679470"}}NCT01679470) for thermal ablation of solid and metastatic lung tumors, and NU-0129 (Northwestern, ClinicalTrials.gov Identifier {"type":"clinical-trial","attrs":{"text":"NCT03020017","term_id":"NCT03020017"}}NCT03020017) for patients with recurrent glioblastoma multiforme or gliosarcoma [ 161]. The plant can brighten up the surface of your tank with its vibrant green color. The roots will depend on the nutrients in the tank’s water to grow.
