Gallic acid and/or cerium oxide nanoparticles synthesized by gamma-irradiation protect cisplatin-induced nephrotoxicity via modulating oxidative stress, inflammation and apoptosis. Arch Biochem Biophys 2023; 740:109594. [PMID: 37023935 DOI: 10.1016/j.abb.2023.109594] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Revised: 03/26/2023] [Accepted: 03/29/2023] [Indexed: 04/08/2023]
Abstract
Cisplatin is one of the most significant anticancer. However, its use is associated with numerous toxicities especially nephrotoxicity. The main aim of this work was to examine the protective effect of Gallic acid (GA) and/or cerium oxide nanoparticles (CONPs) synthesized by gamma-irradiation on cisplatin-induced nephrotoxicity in rats. To do that, 48 adult male albino rats were separated into eight groups and received GA (100 mg/kg orally) and/or CONPs (15 mg/kg i. p.) for 10 days before injection with a single dose of cisplatin (7.5 mg/kg i. p.). The findings showed that cisplatin treatment impaired kidney functioning as shown by elevated serum levels of urea and creatinine. Additionally, the oxidative stress indicators (MDA and NO), levels of NF-kB, pro-inflammatory cytokines (IL1-and TNF-) and pro-apoptotic proteins (BAX and caspase-3) were raised after cisplatin injection, while levels of intrinsic anti-oxidants (CAT, SOD, and GSH) and anti-apoptotic protein (Bcl-2) were reduced. Moreover, renal toxicity was confirmed by alteration in normal histological architecture of the kidneys. On the other hand, pretreatment with CONPs and/or GA ameliorated cisplatin-induced nephrotoxicity as evidenced by improvement of renal function parameters and levels of oxidative stress, inflammatory and apoptotic markers in renal tissue along with the renal histopathological changes. This study clarifies how GA and CONPs protect against cisplatin-induced nephrotoxicity and demonstrates any potential synergism between them. Therefore, they can be considered as promising nephroprotective agents during chemotherapy.

Oral fluoxetine treatment changes serotonergic sympatho-regulation in experimental type 1 diabetes. Life Sci 2022; 293:120335. [PMID: 35051421 DOI: 10.1016/j.lfs.2022.120335] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2021] [Revised: 01/14/2022] [Accepted: 01/14/2022] [Indexed: 11/28/2022]
Abstract
AIMS This study investigated whether fluoxetine treatment changes the 5-HT regulation on vascular sympathetic neurotransmission in type 1 diabetes. MAIN METHODS Four-week diabetes was obtained by a single alloxan s.c. administration in male Wistar rats, administering fluoxetine for 14 days (10 mg/kg/day; p.o.). Systolic blood pressure, heart rate, glycaemia, body weight (BW) evolution, creatinine, and blood urea nitrogen (BUN) were monitored. Afterward, rats were pithed to perform the vascular sympathetic stimulation. 5-HT1A/1D/2A receptors expression was analysed by Western blot in thoracic aorta. Both i.v. norepinephrine and the electrical stimulation of the spinal sympathetic drive evoked vasoconstrictor responses. KEY FINDINGS Fluoxetine treatment significantly reduced the BW gain, hyperglycaemia, creatinine, and BUN in diabetic rats. The electrical-produced vasopressor responses were greater in untreated than in fluoxetine-treated diabetic rats. 5-HT decreased the sympathetic-produced vasopressor responses. While 5-CT, 8-OH-DPAT and L-694,247 (5-HT1/7, 5-HT1A and 5-HT1D agonists, respectively) reproduced 5-HT-evoked inhibition, the 5-HT2 activation by α-methyl-5-HT augmented the vasoconstrictions. The 5-CT sympatho-inhibition was reversed by 5-HT1A plus 5-HT1D antagonists (WAY-100,635 and LY310762, respectively), whereas ritanserin (5-HT2A antagonist) blocked the α-methyl-5-HT potentiating effect. Norepinephrine-generated vasoconstrictions were increased or diminished by α-methyl-5-HT or 5-CT, respectively. 5-HT1A/1D/2A receptors were expressed at vascular level, being 5-HT1A expression increased by fluoxetine in diabetic rats. SIGNIFICANCE Our findings suggest that fluoxetine improves metabolic and renal profiles, changes the vasopressor responses, and 5-HT receptors modulating sympathetic activity in diabetic rats: 5-HT1A/1D are involved in the sympatho-inhibition, while 5-HT2A is implicated in the sympatho-potentiation, being both effects pre and/or postjunctional in nature.

Abstract
Serotonin reuptake inhibitors (SRIs) are safe and widely used for a variety of indications including depressive disorders, anxiety, and chronic pain. Besides inhibiting the serotonin transporter, these medications have broad-spectrum properties in many systems. Their roles have been studied in cancer, Alzheimer's disease, and infectious processes. The COVID-19 pandemic highlighted the importance of drug repurposing of medications already in use. We conducted a narrative review of current evidence and ongoing research on drug repurposing of SRIs, with a focus on immunomodulatory, antiproliferative, and neuroprotective activity. SRIs may have clinical use as repurposed agents for a wide variety of conditions including but not limited to COVID-19, Alzheimer's disease, and neoplastic processes. Further research, particularly randomized controlled trials, will be necessary to confirm the utility of SRIs for new indications.

Abstract
BACKGROUND/AIM Diclofenac (DIC) is a Nonsteroidal anti-inflammatory drug (NSAID) and consumption of this drug creates side effects such as renal injury. The purpose of this work was to assess the influences of gallic acid (GA) on DIC-induced renal injury in rats. MATERIAL AND METHODS Rats were segregated into five groups. Group 1, control group; Group 2 received DIC-only (50 mg/kg bw, i.p.) for 7 consecutive days; Groups 3, received GA-only (100 mg/kg bw, po) for 7 consecutive days; group 4 received DIC (50 mg/kg bw, i.p.) plus GA (50 mg/kg, po) for 7 consecutive days and group 5 received DIC (50 mg/kg bw, i.p.) plus GA (100 mg/kg, po) for 7 consecutive days. RESULTS The data indicated that the levels of the serum protein carbonyl, sGOT, sGPT, urea, creatinine, uric acid, nitrite content, MDA, serum IL-1β, and the renal IL-1β gene expression were remarkably increased in DIC-only treated animals compared to control group. In the other hand, treatment with gallic acid led to significant improvements in abnormalities of DIC-induced oxidative stress and serum biochemical parameters. Histological changes were also ameliorated by GA oral administration. CONCLUSION The results indicated that oral injection of GA could alleviate the noxious effects of DIC on the antioxidant defense system and renal tissue.

Abstract
Depressive disorders are amongst the greatest mental health challenges, with an increasing number of patients being diagnosed each year. Though it has not yet been fully elucidated, redox metabolism imbalances and oxidative stress seem to play a major role in the pathogenesis of depressive disorders. Selective serotonin reuptake inhibitors (SSRIs) are the most prescribed antidepressants, considered to have a better tolerability. However, several adverse effects have been reported and the mechanisms involved in their pharmacological activity are not entirely understood. SSRIs have been shown to influence the redox metabolism, which could be involved in their toxicity and pharmacological effects. A comparative analysis of published in vivo and in vitro data regarding the activity of SSRIs on the redox metabolism pathways has been performed in this paper, with an emphasis on mechanistical aspects. Furthermore, a comparison between oxidative stress biomarker levels reported by different studies was attempted. The reviewed data point towards both pro- and antioxidant effects of SSRIs, dependent on tissue/cell type and dose/concentration, suggest a redox modulating potential of these compounds. In hepatic and testicular tissue, the majority of reviewed studies reported pro-oxidant effects, with possible implications towards the hepatotoxicity and sexual dysfunction that were reported following SSRI treatment; while in brain, the most common findings were antioxidant effects that could partially explain their antidepressant activity. However, given the heterogeneity of the reviewed data, further research is needed to fully understand the impact of SSRIs on redox metabolism and its implications.

Abstract
BACKGROUND Despite the progress in the treatment of acute kidney injury (AKI), current curative approaches fail to provide adequate treatment. In this study, we aimed to investigate the possible protective effects of thymosin-β-4(Tβ4) on an ischemic AKI model in rats. METHODS Rats were randomly assigned into four groups (n = 8/group): The control group (sham-operated), the ischemia-reperfusion (I/R) group; renal ischemia (90 min) by infrarenal abdominal aortic occlusion followed by reperfusion (3 h), the Tβ4 + I/R group; treated with Tβ4 before I/R, and the I/Tβ4/R group; treated with Tβ4 just before reperfusion. Besides renal function determination (creatinine (Cr) and blood urea nitrogen (BUN)); histological evaluation was also conducted. Renal tissue caspase-9, matrix metalloproteinase (MMP-9) activities, and hyaluronan levels were measured. Additionally, renal tissue oxidative stress (lipid hydroperoxide, malondialdehyde, superoxide dismutase, glutathione, pro-oxidant-antioxidant balance, ferric reducing antioxidant power, nitric oxide), inflammation (tumor necrosis factor-α, interleukin-1β, interleukin-6, nuclear factor-κβ) were evaluated. RESULTS I/R increased the level of caspase-9, MMP-9 activity, and hyaluronan (p < 0.001) and these were significantly decreased in both Tβ4 groups. Moreover, I/R led to increases in oxidative stress and inflammation parameters (p < 0.001) while the levels of antioxidants were decreased. Nevertheless, Tβ4 in both groups were able to restore oxidative stress and inflammation parameters. Furthermore, Tβ4 attenuated histologic injury caused by I/R (p < 0.01) and diminished serum urea-creatinine levels (p < 0.001). CONCLUSION These results suggest that Tβ4 has significant improving effects in ischemic acute kidney injury. This beneficial effect might be a result of the inhibition of extracellular matrix remodeling and apoptosis cascade via modulation in renal redox status and inflammation.

Protective Effect of Thymosin β4 against Abdominal Aortic Ischemia-Reperfusion-Induced Acute Lung Injury in Rats. ACTA ACUST UNITED AC 2019; 55:medicina55050187.

Abstract
Background and objectives: Ischemia-reperfusion (IR) caused by infrarenal abdominal aorta cross-clamping is an important factor in the development of ischemia-reperfusion injury in various distant organs. Materials and Methods: We investigated potential antioxidant/anti-inflammatory effects of thymosin beta 4 (Tβ4) in a rat model of abdominal aortic surgery-induced IR. Tβ4 (10 mg/kg, intravenous (i.v.)) was administered to rats with IR (90-min ischemia, 180-min reperfusion) at two different periods. One group received Tβ4 1 h before ischemia, and the other received 15 min before the reperfusion period. Results: Results were compared to control and non-Tβ4-treated rats with IR. Serum, bronchoalveolar lavage fluid and lung tissue levels of oxidant parameters were higher, while antioxidant levels were lower in the IR group compared to control. IR also increased inflammatory cytokine levels. Tβ4 reverted these parameters in both Tβ4-treated groups compared to the untreated IR group. Conclusions: Since there is no statistical difference between the prescribed results of both Tβ4-treated groups, our study demonstrates that Tβ4 reduced lung oxidative stress and inflammation following IR and prevented lung tissue injury regardless of timing of administration.

Abstract
Background Neuroinflammation is closely associated with functional outcome in subarachnoid hemorrhage (SAH) patients. Our recent study demonstrated that fluoxetine inhibited NLRP3 inflammasome activation and attenuated necrotic cell death in early brain injury after SAH, while the effects and potential mechanisms of fluoxetine on neuroinflammation after SAH have not been well-studied yet. Methods One hundred and fifty-three male SD rats were subjected to the endovascular perforation model of SAH. Fluoxetine (10 mg/kg) was administered intravenously at 6 h after SAH induction. TAK-242 (1.5 mg/kg), an exogenous TLR4 antagonist, was injected intraperitoneally 1 h after SAH. SAH grade, neurological scores, brain water content, Evans blue extravasation, immunofluorescence/TUNEL staining, quantitative real-time polymerase chain reaction (qRT-PCR), and western blot were performed. Results Fluoxetine administration attenuated BBB disruption, brain edema, and improved neurological function after SAH. In addition, fluoxetine alleviated the number of Iba-1-positive microglia/macrophages, neutrophil infiltration, and cell death. Moreover, fluoxetine reduced the levels of pro-inflammatory cytokines, downregulated the expression of TLR4 and MyD88, and promoted the nuclear translocation of NF-κB p65, which were also found in rats with TAK-242 administration. Combined administration of fluoxetine and TAK-242 did not enhance the neuroprotective effects of fluoxetine. Conclusion Fluoxetine attenuated neuroinflammation and improved neurological function in SAH rats. The potential mechanisms involved, at least in part, TLR4/MyD88/NF-κB signaling pathway.

Abstract
Depression is very common in asthmatic patients and may increases risk for morbidity and mortality. The present work aimed to investigate the protective effect of fluoxetine, on behavioral and biochemical changes, associated with ovalbumin (OVA) - induced bronchial asthma and depression in rats. Rats were sensitized with intraperitoneal administration of OVA plus aluminum hydroxide for 3 consecutive days then at day 11 followed by OVA intranasal challenge at days 19, 20, 21. Rats were either pretreated with dexamethasone, fluoxetine10mg/kg or fluoxetine 20 mg/kg. At the end of the experiment, various tests were performed, including open field, forced swimming and respiratory function tests. Blood was drawn for serum IgE detection. Finally, rats were euthanized, brain-derived neurotrophic factor (BDNF) was estimated in bronchoalveolar lavage (BAL) fluid and lung content of reduced glutathione (GSH), superoxide dismutase (SOD), tumor necrosis factor-alpha (TNF-α) and interleukin 4 (IL-4) were determined. Histopathological study was also performed. The results showed that fluoxetine significantly ameliorated OVA- induced biochemical and behavioral changes. Fluoxetine may protect against OVA-induced asthma and depression in rats. This effect may be mediated at least in part by its antioxidant, anti-inflammatory and immunosuppressant effect.

Barakat A, Hamdy MM, Elbadr MM. Uses of fluoxetine in nociceptive pain management: A literature overview. Eur J Pharmacol 2018; 829:12-25. [PMID: 29608897 DOI: 10.1016/j.ejphar.2018.03.042] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2018] [Revised: 03/28/2018] [Accepted: 03/29/2018] [Indexed: 12/16/2022]
Abstract
Fluoxetine is one of the top ten prescribed antidepressants. Other therapeutic applications were approved for fluoxetine including, anxiety disorders, bulimia nervosa, and premature ejaculation. However, the role of fluoxetine in nociceptive pain management is still unclear. In this review, we discuss an overview of five possible roles of fluoxetine in pain management: intrinsic antinociceptive effect, enhancement of acute opioid analgesia, attenuation of tolerance development to opioid analgesia, attenuation of dependence development and abstinence syndrome, and attenuation of opioid induced hyperalgesia. Conflicting data were reported about fluoxetine intrinsic anti-nociceptive effect in preclinical and clinical studies except for inflammatory pain. Similar controversy was described in preclinical and clinical studies which explored the possible enhancement of opioid analgesia by fluoxetine co-administration. However, fluoxetine was found to have a promising effect on opioid tolerance and dependence in animal and human studies. Regarding opioid induced hyperalgesia, no studies examined fluoxetine effects in this regard. Our literature review revealed that, the most likely beneficial use of fluoxetine in nociceptive pain management is for alleviation of inflammatory pain and attenuation of opioid tolerance and dependence. Non-steroidal anti-inflammatory and corticosteroids carry many adverse effects and toxicities. Effective alleviation of opioid tolerance and dependence represents a huge health burden and growing unmet medical need. Moreover, most agents used to attenuate these phenomena are either experimental or poorly tolerable drugs which limit their transitional value. Fluoxetine offers an effective, safe, and tolerable alternative for management of both inflammatory pain and opioid tolerance and dependence presently available to clinicians.

Danshen injection ameliorates STZ-induced diabetic nephropathy in association with suppression of oxidative stress, pro-inflammatory factors and fibrosis. Int Immunopharmacol 2016; 38:385-94.

Abstract
Diabetic nephropathy (DN) is one of the most frequent complications in diabetes mellitus. This study aimed to explore whether Danshen injection is protective to renal tissue in diabetes. Intraperitoneal injection of streptozotocin (STZ) (60mg/kg) was used to induce diabetes in rats. Some STZ-induced diabetic rats were also intraperitoneally injected with Danshen solution at two different dosages (0.5 or 1ml/kg/day) for 6weeks. Our results showed that serum creatinine (sCr) and blood urea nitrogen were significantly increased in STZ-induced diabetic rats, which was alleviated upon Danshen injection. Danshen injection was also found to ameliorate hypertrophy and dilatation of renal tubule and glomeruli possibly by decreasing the expression of collagen and fibronectin in association with suppression of TGF-β1/Smad pathway. Further investigation revealed that Danshen injection could increase the activity of superoxide dismutase (SOD), and reduce reactive oxygen species (ROS) and malondialdehyde (MDA) levels in STZ-induced diabetic rats, indicating suppression of oxidative stress. In addition, we also found that Danshen injection could suppress IκB/NF-κB signaling pathway and reduce the level of a number of pro-inflammatory factors, including tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and interleukin-6 (IL-6) in the diabetic renal tissue, indicating suppression of inflammation. In conclusion, our results demonstrated that Danshen injection may rescue STZ-induced diabetic nephropathy, possibly via suppressing the oxidative stress, inflammatory responses and fibrosis progression.

Abstract
Protein restriction during prenatal, postnatal, or in both periods has a close relationship with subsequent development of cardiovascular disease in adulthood. Elevated brain levels of serotonin and its metabolites have been found in malnourished states. The aim in the present study was to investigate whether treatment with fluoxetine (Fx), a selective serotonin reuptake inhibitor, mimics the detrimental effect of low-protein diet during the perinatal period on the male rat heart. Our hypothesis is that increased circulating serotonin as a result of pharmacologic treatment with Fx leads to cardiac dysfunction similar to that observed in protein-restricted rats. Male Wistar rat pups received daily subcutaneous injection of Fx or vehicle from postnatal day 1 to postnatal day 21. Male rats were euthanized at 60 days of age and the following parameters were evaluated in the cardiac tissue: mitochondrial respiratory capacity, respiratory control ratio, reactive oxygen species (ROS) production, mitochondrial membrane potential, and biomarkers of oxidative stress and antioxidant defense. We found that Fx treatment increased mitochondrial respiratory capacity (123%) and membrane potential (212%) and decreased ROS production (55%). In addition we observed an increase in the antioxidant capacity (elevation in catalase activity (5-fold) and glutathione peroxidase (4.6-fold)). Taken together, our results suggest that Fx treatment in the developmental period positively affects the mitochondrial bioenergetics and antioxidant defense in the cardiac tissue.

Nephroprotective Effects of Polydatin against Ischemia/Reperfusion Injury: A Role for the PI3K/Akt Signal Pathway. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2015; 2015:362158.

Abstract
Oxidative stress and inflammation are involved in the pathogenesis in renal ischemia/reperfusion (I/R) injury. It has been demonstrated that polydatin processed the antioxidative, anti-inflammatory, and nephroprotective properties. However, whether it has beneficial effects and the possible mechanisms on renal I/R injury remain unclear. In our present study I/R models were simulated both in vitro and in vivo. Compared with vehicle control, the administration of polydatin significantly improved the renal function, accelerated the mitogenic response and reduced cell apoptosis in renal I/R injury models, strongly suppressed the I/R-induced upregulation of the expression of tumor necrosis factor-α, interleukin-1β, cyclooxygenase-2, inducible nitric oxide synthase, prostaglandin E-2, and nitric oxide levels, and dramatically decreased contents of malondialdehyde, but it increased the activity of superoxide dismutase, glutathione transferase, glutathione peroxidase and catalase, and the level of glutathione. Further investigation showed that polydatin upregulated the phosphorylation of Akt in kidneys of I/R injury dose-dependently. However, all beneficial effects of polydatin mentioned above were counteracted when we inhibited PI3K/Akt pathway with its specific inhibitor, wortmannin. Taken together, the present findings provide the first evidence demonstrating that PD exhibited prominent nephroprotective effects against renal I/R injury by antioxidative stress and inflammation through PI3-K/Akt-dependent molecular mechanisms.

Abstract
Recent investigations have focused on the mitochondrion as a direct drug target in the treatment of metabolic diseases (obesity, metabolic syndrome). Relatively few studies, however, have explicitly investigated whether drug therapies aimed at changing behavior by altering central nervous system (CNS) function affect mitochondrial bioenergetics, and none has explored their effect during early neonatal development. The present study was designed to evaluate the effects of chronic treatment of newborn male rats with the selective serotonin reuptake inhibitor fluoxetine on the mitochondrial bioenergetics of the hypothalamus and skeletal muscle during the critical nursing period of development. Male Wistar rat pups received either fluoxetine (Fx group) or vehicle solution (Ct group) from the day of birth until 21 days of age. At 60 days of age, mitochondrial bioenergetics were evaluated. The Fx group showed increased oxygen consumption in several different respiratory states and reduced production of reactive oxygen species, but there was no change in mitochondrial permeability transition pore opening or oxidative stress in either the hypothalamus or skeletal muscle. We observed an increase in glutathione S-transferase activity only in the hypothalamus of the Fx group. Taken together, our results suggest that chronic exposure to fluoxetine during the nursing phase of early rat development results in a positive modulation of mitochondrial respiration in the hypothalamus and skeletal muscle that persists into adulthood. Such long-lasting alterations in mitochondrial activity in the CNS, especially in areas regulating appetite, may contribute to permanent changes in energy balance in treated animals.

Abstract
BACKGROUND Fluoxetine, a selective serotonin reuptake inhibitor, has been reported to reduce periodontal disease severity in a rat ligature-induced periodontitis model. The objective of the present study is to investigate the influence of fluoxetine intake on periodontal parameters in patients with periodontitis with clinical depression. METHODS A sample of 236 patients with chronic periodontitis and clinical depression were assessed for clinical parameters of periodontal disease. Of these, 115 patients were taking fluoxetine (20 mg/day) for ≥2 months, and 121 patients were not. Participants taking fluoxetine were further analyzed for correlation between duration of drug intake and periodontal parameters. RESULTS All periodontal parameters, except plaque index, were significantly lower in participants taking fluoxetine (P <0.01). Partial correlation analysis, adjusted for confounders, revealed a significant and negative correlation between duration of fluoxetine intake and attachment loss (AL) (R(2) = -0.321, P <0.05). Logistic regression analysis revealed that fluoxetine intake was associated with a lower risk of having AL ≥3 (odds ratio [OR] = 0.55, 95% confidence interval [CI] = 0.31 to 0.96) and lower odds of increased bleeding on probing (BOP) percentage values (OR = 0.62, 95% CI = 0.34 to 0.97). CONCLUSION In this observational study, use of fluoxetine was associated with lower BOP percentages and reduced AL.

Abstract
Both acute kidney injury (AKI) and chronic kidney disease (CKD) that lead to diminished kidney function are interdependent risk factors for increased mortality. If untreated over time, end stage renal disease (ESRD) is an inevitable outcome. Acute and chronic kidney diseases occur partly due to imbalance between the molecular mechanisms that govern oxidative stress, inflammation, autophagy and cell death. Oxidative stress refers to the cumulative effects of highly reactive oxidizing molecules that cause cellular damage. Autophagy removes damaged organelles, protein aggregates and pathogens by recruiting these substrates into double membrane vesicles called autophagosomes which subsequently fuse with lysosomes. Mounting evidence suggests that both oxidative stress and autophagy are significantly involved in kidney health and disease. However, very little is known about the signaling processes that link them. This review is focused on understanding the role of oxidative stress and autophagy in kidney diseases. In this review, we also discuss the potential relationships between oxidative stress and autophagy that may enable the development of better therapeutic intervention to halt the progression of kidney disease and promote its repair and resolution. The molecular mechanisms underlying the regulation of oxidative stress responses and autophagy may exhibit considerable cross-talk. The autophagy pathway may be regulated in the context of kidney diseases. Failure or disruption of the autophagy pathway may contribute to the pathogenesis of kidney diseases. Targeting the autophagy pathway may show considerable therapeutic potential in the treatment and management of kidney disorders.
