For the avoidance of doubt, this Section 4 supplements and does not replace Your obligations under this Public License where the Licensed Rights include other Copyright and Similar Rights.

This includes, without limitation, warranties of title, merchantability, fitness for a particular purpose, non-infringement, absence of latent or other defects, accuracy, or the presence or absence of errors, whether or not known or discoverable. Where disclaimers of warranties are not allowed in full or in part, this disclaimer may not apply to You. To the extent possible, in no event will the Licensor be liable to You on any legal theory (including, without limitation, negligence) or otherwise for any direct, special, indirect, incidental, consequential, punitive, exemplary, or other losses, costs, expenses, or damages arising out of this Public License or use of the Licensed Material, even if the Licensor has been advised of the possibility of such losses, costs, expenses, or damages.

The disclaimer of warranties and limitation of liability provided above shall be interpreted in a manner that, to the extent possible, most closely approximates an absolute disclaimer and waiver of all liability. Section 6 – Term and Termination. This Public License applies for the term of the Copyright and Similar Rights licensed here. However, if You fail to comply with this Public License, then Your rights under this Public License terminate automatically. Where Your right to use the Licensed Material has terminated under Section 6(a), it reinstates: automatically as of the date the violation is cured, provided it is cured within 30 days of Your discovery of the violation; or upon express reinstatement by the Licensor. For the avoidance of doubt, this Section 6(b) does not affect any right the Licensor may have to seek remedies for Your violations of this Public License. For the avoidance of doubt, the Licensor may also offer the Licensed Material under separate terms or conditions or stop distributing the Licensed Material at any time; however, doing so will not terminate this Public License. Sections 1, 5, 6, 7, and 8 survive termination of this Public License. Section 7 – Other Terms and Conditions. The Licensor shall not be bound by any additional or different terms or conditions communicated by You unless expressly agreed.

To the extent possible, if any provision of this Public License is deemed unenforceable, it shall be automatically reformed to the minimum extent necessary to make it enforceable. If the provision cannot be reformed, it shall be severed from this Public License without affecting the enforceability of the remaining terms and conditions. No term or condition of this Public License will be waived and no failure to comply consented to unless expressly agreed to by the Licensor. Nothing in this Public License constitutes or may be interpreted as a limitation upon, or waiver of, any privileges and immunities that apply to the Licensor or You, including from the legal processes of any jurisdiction or authority.

Biological synthesis of silver nanoparticles using Citrus sinesis seeds: Effects on hepatic and renal functional integrities and antioxidant activities.
Abstract
Objective: This work reports the possible toxicological effects of AgNPs on the liver and kidney. Additionally, it also beamed its searchlight on its effects on the antioxidant defense mechanism in male Wistar rats.
Method: Male Wistar rats (n=28) were used for the study. Control animals (n=7) were exposed to only drinking ware ad-libitum for 12 weeks. The remaining 21 rats were randomized into 3 groups of 7 animals each and were exposed to 50, 150 and 250 kg/mg body weight AgNPs biosynthesized from Citrus sinensisi for the same period after which blood and liver were removed from the rats and analyzed spectrophotometrically.
Results: A non-significant reduction of plasma ALT, AST, ?GT and ALP characterized the effects of AgNPs in the animal tested. Similarly, AgNPs significantly depleted the plasma creatinine and urea level. The exposure also up-regulated the activities/concentration of antioxidant markers. Malondialdehyde concentration was also significantly depleted by AgNPs.
Conclusion: The findings from this study revealed that biologically synthesized AgNPs induced no toxicological potential on hepatic and renal structural and functional integrity. Meanwhile, it enhanced the activities and concentration of antioxidant markers.
