Abstract
Captive breeding has been explored in Chinese sturgeon (Acipenser sinensis) for species protection. However, gonad development from stage II to IV of cultured female broodstocks is a handicap. This study aimed to explore the physiological and metabolic changes during the ovary development from stage II to IV of female Chinese sturgeon and the related energy regulatory mechanism, which may be helpful to address the developmental obstacle. The results showed that the oocyte volume increased and the muscle lipid content decreased with the ovary development. Ovarian RNA levels of most genes related to lipid and amino acid metabolism were higher in stage II and III than in stage IV. Serum contents of differential metabolites in arginine, cysteine, methionine, purine, tyrosine, lysine, valine, leucine and isoleucine metabolism pathways peaked at stage III, while the contents of sarcosine, alanine and histidine, as well as most oxylipins derived from fatty acids peaked at stage IV. These results indicated the more active amino acids, lipid metabolism, and energy dynamics of fish body in response to the high energy input of ovary developing from stage II to III, and the importance of alanine, histidine, taurine, folate and oxylipins for fish with ovary at stage IV.

Abstract
Induction and activation of arginase is among the fastest responses of the heart to ischemic events. Induction of arginase expression and enzyme activation under ischemic conditions shifts arginine consumption from nitric oxide formation (NO) to the formation of ornithine and urea. In the heart such a switch in substrate utilization reduces the impact of the NO/cGMP-pathway on cardiac function that requires intact electromechanical coupling but at the same time it induces ornithine-dependent pathways such as the polyamine metabolism. Both effects significantly reduce the recovery of heart function during reperfusion and thereby limits the success of reperfusion strategies. In this context, changes in arginine consumption trigger cardiac remodeling in an unfavorable way and increases the risk of arrhythmia, specifically in the initial post-ischemic period in which arginase activity is dominating. However, during the entire ischemic period arginase activation might be a meaningful adaptation that is specifically relevant for reperfusion following prolonged ischemic periods. Therefore, a precise understanding about the underlying mechanism that leads to arginase induction as well as of it's mechanistic impact on post-ischemic hearts is required for optimizing reperfusion strategies. In this review we will summarize our current understanding of these processes and give an outlook about possible treatment options for the future.

Abstract
BACKGROUND Previous studies found that urea transporter UT-B is abundantly expressed in bladder urothelium. However, the dynamic role of UT-B in bladder urothelial cells remains unclear. The objective of this study is to evaluate the physiological roles of UT-B in bladder urothelium using UT-B knockout mouse model and T24 cell line. METHODOLOGY/PRINCIPAL FINDINGS Urea and NO measurement, mRNA expression micro-array analysis, light and transmission electron microscopy, apoptosis assays, DNA damage and repair determination, and intracellular signaling examination were performed in UT-B null bladders vs wild-type bladders and in vitro T24 epithelial cells. UT-B was highly expressed in mouse bladder urothelium. The genes, Dcaf11, MCM2-4, Uch-L1, Bnip3 and 45 S pre rRNA, related to DNA damage and apoptosis were significantly regulated in UT-B null urothelium. DNA damage and apoptosis highly occurred in UT-B null urothelium. Urea and NO levels were significantly higher in UT-B null urothelium than that in wild-type, which may affect L-arginine metabolism and the intracellular signals related to DNA damage and apoptosis. These findings were consistent with the in vitro study in T24 cells that, after urea loading, exhibited cell cycle delay and apoptosis. CONCLUSIONS/SIGNIFICANCE UT-B may play an important role in protecting bladder urothelium by balancing intracellular urea concentration. Disruption of UT-B function induces DNA damage and apoptosis in bladder, which can result in bladder disorders.

Abstract
OBJECTIVE To investigate the interactions between inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in response to ischaemia-reperfusion (I/R) of rabbit bladder. MATERIALS AND METHODS Rabbit bladders were exposed to 2 h of ischaemia by bilaterally clamping the major arteries entering the bladder and then a subsequent 36 h of reperfusion (I/R) with or without intraperitoneal administration of a selective iNOS inhibitor n-(3-(amynomethyl)benzyl)acetamidine (1400W) or a selective COX-2 inhibitor NS-398 given 1 h before killing. The bladder tissues were processed for isometric tension experiments, enzymatic NOS activitiy, tissue contents of nitrite/nitrate (NO(X) ), cyclic guanosine monophosphate (cGMP) and COX activity determined by prostaglandin E(2) (PGE(2) ) production. RESULTS iNOS and constitutive NOS (cNOS) activities, NO(X) and PGE(2) contents in the bladder tissues at 36 h after reperfusion were significantly higher than those in the sham group with no significant increase in cGMP. Treatment with 1400W abrogated the increases in iNOS activity and NO(X) as well as PGE(2) without changing cNOS activity. In the tension experiments, a NOS substrate, l-arginine, induced detrusor contraction only in the I/R group, which was inhibited by 1400W or NS-398 but not by a selective soluble guanylate cyclase inhibitor 1H-[1,2,4] oxadiazole[4,3-a]quinoxalin-1-one (ODQ). 8-Br-cGMP induced detrusor relaxation in the sham and I/R groups. Also, l-arginine increased NO(X) and PGE(2) in the bladder tissues only in the I/R group, which were inhibited by pretreatment with 1400W. While, l-arginine increased cGMP contents in the I/R group and this increase was suppressed by ODQ but not by 1400W. CONCLUSION These results show that NO derived from an up-regulation of iNOS after I/R increases COX-2-derived PG via a cGMP-independent mechanism. NO-mediated activation of COX-2 may be an important mechanism for the modulation of bladder function after I/R injury.

Abstract
Dehydroepiandrosterone (DHEA) has been implicated not only to prevent N-methyl-D-aspartate (NMDA)-induced neurotoxicity but also to enhance Ca(2+) influx through NMDA receptor (NMDAr). However, these DHEA effects, which would produce inconsistent outcomes about neuronal damages, are not well studied in ischemia-induced cerebral damages. Herein, we report that a single administration of DHEA (20 mg/kg) during 3 to 48 h after transient global cerebral ischemia in rats exerted neuroprotective effects such as reduction of ischemia-induced neuronal death in the hippocampal CA1 and improvement of ischemia-induced deficits in spatial learning. By contrast, at 1 h before or after ischemia, the administration of DHEA exacerbated the ischemia-induced neuronal death and learning impairment. This DHEA neurotoxicity appeared to be caused by DHEA itself, but not through its metabolite testosterone, and was inhibited by a pretreatment with the NMDAr blocker MK801 or the sigma-1 (sigma(1)) receptor antagonist NE100. However, the DHEA neuroprotection was blocked by NE100. These results show that DHEA not only provides robust ischemic neuroprotection with a long therapeutic opportunity but also exerts neurotoxicity when administered during ischemia and early reperfusion, which points to the importance of administration timing of DHEA in the clinical treatment of brain damages by the transient brain ischemia including stroke.

Abstract
OBJECTIVES We investigated the effects of an arginase inhibitor on bladder overactivity and measured bladder arginase I and II mRNA levels in rats with chronic spinal cord injury (SCI). METHODS We performed awake cystometrograms 3 to 4 weeks after spinal cord transection in female rats. Cystometric parameters such as mean amplitudes and number of non-voiding contractions (NVCs), voided volume, voiding efficiency, and micturition pressure were evaluated before and after intravenous (i.v.) injection of an arginase inhibitor (nor-NOHA: N(omega)-hydroxy-nor-L-arginine) in SCI rats. We also examined the effects of an NOS inhibitor (L-NAME: N(omega)-nitro-L-arginine methyl ester hydrochloride) to determine whether suppression of bladder overactivity by arginase inhibition is mediated by increased production of NO. In addition, we measured mRNA levels of arginase I and II in SCI bladders using quantitative real-time polymerase chain reaction (qRT-PCR). RESULTS We found that nor-NOHA (10 mg/kg, i.v.) significantly decreased the amplitude and number of NVCs. There were no significant changes in other parameters before and after administration of vehicle or nor-NOHA at any dose. When we administered L-NAME (20 mg/kg, i.v.) before nor-NOHA injection (10 mg/kg, i.v.), nor-NOHA-induced inhibition of NVCs was prevented. The relative levels of both arginase I and II mRNA in the bladder were significantly higher in SCI rats compared with spinal cord-intact rats. CONCLUSIONS These results suggest that arginase inhibition can suppress SCI-induced bladder overactivity as indicated by a reduction in NVCs. Thus, arginase inhibition could be an effective treatment for neurogenic bladder overactivity in pathological conditions such as SCI.

Abstract
The aim of our study is to investigate the effects of chronic sacral neuromodulation on Nitric Oxide (NO) metabolism in the rat bladder. 26 female Sprangue-Dawley rats were considered: group I, normal control rats; group II, a sham treatment, in whom catheters for electrical stimulation were placed in the S1 foramen bilaterally and left in place for 21 days, without performing neuromodulation; group III in whom electrical sacral neuromodulation was performed for 21 days. Finally a cystectomy was performed and the bladder biopsy specimens were sent for immunostaining with n-NOS and i-NOS. Morphological and immunohistochemical analysis was carried out, and evaluated in urothelial cells, endothelial cells and muscle fibers of the muscularis propria. Differences between the 3 groups were analyzed by Student Newman-Keuls test. We could observe that urothelial and endothelial i-NOS (37.00±4.69 and 59.00±7.42 respectively) and urothelial n-NOS (36.80±7.85) expression are significantly increased in neuromodulated rats, compared to groups 1 and 2 (p < 0.005). In conclusion, the increase of i-NOS expression on endothelial cells after sacral neuromodulation could be in some way related to angiogenetic responses in the microvascular structures; the increase of n-NOS and i-NOS expression on urothelial cells can suggest that NO is able to influence the plasticity of bladder response, inducing the release of messengers within the urothelium. This study can therefore improve our understanding of the mechanisms of sacral neuromodulation on chronic bladder dysfunction; further studies will need to better demonstrate the role of angiogenesis in the bladder after sacral neuromodulation and to investigate the effects of neuromodulation in rats with chronically induced bladder dysfunction.
