Abstract
Testicular torsion is a urological emergency that involves the twisting of the spermatic cord along its course. Compelling pieces of evidence have implicated oxidative stress-sensitive signaling in pathogenesis of testicular I/R injury. Although, surgical detorsion is the mainstay management; blockade of the pathways involved in the pathogenesis may improve the surgical outcome. Experimental studies using various testicular I/R models have been reported in a bid to explore the mechanisms associated with testicular I/R and evaluate the benefits of potential therapeutic measures; however, most are limited by their shortcomings. Thus, this review was intended to describe the details of the available testicular I/R models as well as their merits and drawbacks, the pathophysiological basis and consequences of testicular I/R, and the pharmacological agents that have being proposed to confer testicular benefits against testicular I/R. This provides an understanding of the pathophysiological events and available models used in studying testicular I/R. In addition, this research provides evidence-based molecules with therapeutic potentials as well as their mechanisms of action in testicular I/R.

Abstract
Testicular torsion is twisting of the spermatic cord around its axis, which impairs blood flow and causes ischemia and formation of free radicals. Ferulic acid is a phenolic acid of the hydroxycinnamic family that is found in the seeds and leaves of plants; it is present in substantial amounts in fruits and vegetables. We investigated the protective effect of ferulic acid on experimental testicular torsion in rats. Animals were divided randomly into five groups: control, ethyl alcohol, torsion, torsion-detorsion, and torsion-detorsion + ferulic acid. Histopathology was assessed using hematoxylin and eosin, and periodic acid-Schiff staining. Tissues were assessed using TUNEL, active caspase-3, myeloperoxidase and inducible nitric oxide synthase immunostaining. Biochemical changes were assessed using assays for superoxide dismutase, malondialdehyde, glutathione peroxidase and glutathione. Ferulic acid reduced the levels of free radicals and increased the levels of antioxidants. Ferulic acid also reduced histopathological changes and germ cell differentiation in the testis following torsion-detorsion. Ferulic acid should be investigated further as a potential treatment for sequelae of torsion-detorsion injury.

Salidroside Exerts Beneficial Effect on Testicular Ischemia-Reperfusion Injury in Rats. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2022; 2022:8069152. [PMID: 35602096 PMCID: PMC9117026 DOI: 10.1155/2022/8069152] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/20/2022] [Revised: 04/14/2022] [Accepted: 04/19/2022] [Indexed: 11/17/2022]
Abstract
Testicular torsion-detorsion results in testicular ischemia-reperfusion injury, which is associated with overgeneration of reactive oxygen species. Salidroside, a major bioactive ingredient extracted from Rhodiola rosea, has strong antioxidant activity. The purpose of this study was to examine the effect of salidroside on testicular ischemia-reperfusion injury. Sixty rats were randomly separated into 3 experimental groups: group A = sham-operated control; group B = testicular ischemia-reperfusion; and group C = testicular ischemia-reperfusion treated with salidroside. The rats in the sham-operated control group received all surgical procedures except testicular torsion-detorsion. The testicular ischemia-reperfusion group underwent 2 hours of left testicular torsion followed by detorsion. The rats in the salidroside-treated group received the same surgical procedure as in testicular ischemia-reperfusion group, but salidroside was injected intraperitoneally at reperfusion. Testicular malondialdehyde content (a reliable index of reactive oxygen species) and protein expression of superoxide dismutase and catalase which are primary antioxidant enzymes in testes were measured at 4 hours after reperfusion. Testicular spermatogenesis was evaluated at 3 months after reperfusion. The malondialdehyde content increased significantly, while superoxide dismutase and catalase protein expression and testicular spermatogenesis reduced significantly in ipsilateral testes of testicular ischemia-reperfusion group, as compared with sham-operated control group. Therapy with salidroside significantly reduced malondialdehyde content and significantly enhanced superoxide dismutase and catalase protein expression and spermatogenesis in ipsilateral testes, as compared with testicular ischemia-reperfusion group. The present findings indicate that treatment with salidroside ameliorates testicular ischemia-reperfusion injury by reducing reactive oxygen species level by upregulating superoxide dismutase and catalase protein expression.

Abstract
Manganese (Mn) pollution is an important environmental problem because of the potential toxicity to human and animal health. However, the effects of Mn on energy metabolism and autophagy are not clear. Consequently, we examined the effects of excessive and chronic exposure to Mn on liver function, oxidative stress, respiratory chain complex activity, and autophagy in chicken liver. Our results indicated that the accumulation of Mn in the liver and levels of AST and ALT in the serum of the Mn-exposed group were significantly higher (P < 0.05) than those in the control group at 90 days; the activities of GSH-Px, SOD, CAT, Na+-K+-ATPase, Mg2+-ATPase, Ca2+-ATPase, and respiratory chain complexes (I, II, III) in the Mn-exposed group were significantly decreased (P < 0.05) compared to the control group. However, the MDA content, NO content, iNOS activity, mRNA and protein levels of iNOS, and autophagy-related genes in the Mn-exposed group were significantly increased (P < 0.05) compared to the control group. In contrast, the mRNA level and protein expression of mTOR were significantly decreased (P < 0.05) compared to the control group. Furthermore, the characteristic autophagic vacuolar organelles were observed in the Mn-exposed group. These results suggested that excess Mn exposure can cause a disorder of energy metabolism by mitochondrial injury and induce oxidative stress and autophagy, which eventually lead to liver damage.

Abstract
Sertoli cell death contributes to spermatogenesis impairment, which is associated with male infertility. Testicular ischemia‑reperfusion (I/R) injury induces the cell death of germ cells and Sertoli cells, whereas inhibition of cell death ameliorates acute testicular I/R damage. The aim of the present study was to investigate the mechanism of I/R stress-induced cell death in TM4 cells. Oxygen‑glucose deprivation and reoxygenation (OGD/R) was demonstrated to induce I/R injury and cell death in TM4 cells. Cell death was blocked by the reactive oxygen species (ROS) inhibitor N‑acetylcysteine, as well as lipid peroxidation inhibitors Liproxstatin‑1 and iron chelator deferoxamine; however, inhibitors of apoptosis, necrosis or autophagy had no effect. It was also demonstrated that iron and lipid ROS levels were elevated in I/R injury and that mitochondria decreased in size and increased in membrane density, which is indicative of ferroptosis. Furthermore, the generation of lipid ROS suggests iron accumulation and glutathione (GSH) depletion. The expression of ferroportin (Fpn) protein and mRNA was decreased in TM4 cells. Notably, overexpression of Fpn inhibited ferroptosis, lipid ROS generation and iron accumulation. In addition, GSH‑dependent peroxidase 4 (GPX4) was inactivated via GSH depletion following I/R injury, whereas GPX4 activation blocked I/R‑induced ferroptosis by reducing lipid ROS levels. The mitogen‑activated protein kinase (MAPK) pathway was also investigated in the present study; it was observed that I/R‑induced ferroptosis was blocked by inhibiting p38 MAPK activation. The results of the present study demonstrate that ferroptosis is a pervasive and dynamic type of cell death induced by OGD/R injury in Sertoli cells. This may provide a novel insight into the application of cytoprotection in testicular I/R damage‑induced cell loss.

Abstract
Purpose of review Rhodiola rosea extracts have been used as a dietary supplement in healthy populations, including athletes, to non-specifically enhance the natural resistance of the body to both physical and behavior stresses for fighting fatigue and depression. We summarize the information with respect to the new pharmacological activities of Rhodiola rosea extracts and its underlying molecular mechanisms in this review article. Recent findings In addition to its multiplex stress-protective activity, Rhodiola rosea extracts have recently demonstrated its anti-aging, anti-inflammation, immunostimulating, DNA repair and anti-cancer effects in different model systems. Molecular mechanisms of Rhodiola rosea extracts's action have been studied mainly along with one of its bioactive compounds, salidroside. Both Rhodiola rosea extracts and salidroside have contrast molecular mechanisms on cancer and normal physiological functions. For cancer, Rhodiola rosea extracts and salidroside inhibit the mTOR pathway and reduce angiogenesis through down-regulation of the expression of HIF-1α/HIF-2α. For normal physiological functions, Rhodiola rosea extracts and salidroside activate the mTOR pathway, stimulate paracrine function and promote neovascularization by inhibiting PHD3 and stabilizing HIF-1α proteins in skeletal muscles. In contrast to many natural compounds, salidroside is water-soluble and highly bioavailable via oral administration and concentrated in urine by kidney excretion. Summary Rhodiola rosea extracts and salidroside can impose cellular and systemic benefits similar to the effect of positive lifestyle interventions to normal physiological functions and for anti-cancer. The unique pharmacological properties of Rhodiola rosea extracts or salidroside deserve further investigation for cancer chemoprevention, in particular for human urinary bladder cancer.

Abstract
Background: Antioxidants are potent scavengers of free radicals and have beneficial effects on human health. Objective: The aim of this study was to investigate the potential protective antioxidant activity of the edible portion of date fruit extract in an experimental testicular torsion/detorsion (T/D) model in rats. Materials and Methods: To investigate the potential protective effects of date palm (DP), 30 male Spraque-Dawley rats were divided into three groups: sham-operated, T/D, and T/D + DP-treated (500 mg/kg, PO) groups. Testicular ischemia was induced via keeping the left testis under 720° clockwise torsion for 2 h (h), afterward, detorsion was performed. All rats were sacrificed 4 h after detorsion. Serum malondialdehyde (MDA) concentration, total oxidative status (TOS), total antioxidant status (TAS), oxidative stress index (OSI), and histopathological damage score were evaluated. Results: Serum MDA, TOS, and OSI levels rose significantly in the T/D group. These values were lower in the T/D + DP group. TAS values decreased significantly in T/D group and rose in T/D + DP group. Severe injury was seen in the twisted testes of T/D group. In contrast, ipsilateral-twisted testicular tissue in the DP-treated group showed moderate-to-mild changes. Contralateral testicular tissue in the T/D group had a mild-to-moderate tissue injury; meanwhile, treated group revealed normal-to-mild changes. Spermatogenesis was significantly improved in DP-treated group when compared with the T/D group. Conclusion: The findings suggest a possible protective effect of DP against testicular oxidative damage induced by T/D; however, more detailed studies are warranted. SUMMARY Given the presence of several phenolic compounds possessing high antioxidant activity in DP, it could potentially be used to reduce testis ischemia/reperfusion-induced damage.

Abstract
Rhodiola rosea L. (roseroot) is a common member of the family Crassulaceae, known as one of the most important popular medicinal plants in the northern region of Europe. The roots of R. rosea possess a wide range of pharmacological activities such as antioxidant, antiinflammatory, anticancer, cardioprotective, and neuroprotective effects that are because of the presence of different phytochemicals such as phenols and flavonoids. In addition, the presence of salidroside, rosavins, and p-tyrosol are responsible for its beneficial effects for the treatment of on depression, fatigue, and cognitive dysfunction. A plethora of studies report that R. rosea has potent neuroprotective effects through the suppression of oxidative stress, neuroinflammation, and excitotoxicity in brain tissues and antagonism of oncogenic p21-activated kinase. However, to our knowledge, no review articles have been published addressing the neuroprotective effects of R. rosea. Therefore, the present article aims at critically reviewing the available literature on the beneficial effects of R. rosea on as a therapeutic strategy for the treatment of Alzheimer's disease and other neurodegenerative diseases where oxidative stress plays a major role in disease development and progression. We also discuss the cultivation, phytochemistry, clinical impacts, and adverse effects of R. rosea to provide a broader insight on the therapeutic potential for this plant.

Abstract
The aim of this study was to evaluate the histopathological and apoptotic changes occurring in the rat ipsilateral and contralateral testes, after experimental spermatic cord torsion, and to explore and the role of poly(ADP-ribose) polymerase (PARP) cleavage in testicular torsion-detorsion injury. A total of 37 Wistar albino rats were subjected to 720° unilateral spermatic cord torsion for 1, 2 and 4 h, followed by 4-h reperfusion, or else to a sham operation (control group). Histology of the testicle was evaluated using haematoxylin-eosin (H&E) staining and Johnsen's scoring system. Germ cell apoptosis was evaluated via active caspase-3 immunostaining, and PARP expression levels were evaluated via Western blotting. The mean Johnsen's tubular biopsy scores (JTBS) of the ipsilateral testicles were lower for all torsion groups than for the controls (P < 0.05), but the JTBS of the contralateral testicles were only lower in the 4-h torsion group (P < 0.05). The mean apoptosis score (AS) of the ipsilateral and contralateral testicles was significantly higher in the torsion groups than in the sham group. AS increased correlatively with torsion time, in both testicles. The effect of testicular torsion on PARP cleavage was time dependent, with the highest effect observed after 4 h of testicular torsion (P < 0.05). Testicular torsion caused time-dependent histological changes, apoptosis and increases in PARP cleavage. Our results suggest that testicular torsion-detorsion injury caused cell damage and germ cell apoptosis that apparently involved cleavage of PARP. Increased PARP cleavage could, in turn, lead to enhanced apoptosis.
