Abstract	A spot urine creatinine-to-osmolality ratio (sUCr/Osm) is proposed as a surrogate of the urinary excretion rate of creatinine (Cr) and convenient for forecasting serum Cr (SCr) trends. The lower the sUCr/Osm, the lower the excreted Cr amount accompanied by per unit of osmoles, the higher the risk of Cr accumulation. For exploring the reference intervals of sUCr/Osm in general adults, a cross-sectional analysis was performed on a subset of data from the National Health and Nutrition Examination Survey (NHANES) 2011–2012. Of the eligible 3,316 adults aged 18.0 to 79.9 years, the age (mean±SD) was 45.2±17.2 years old, women was 45.02%, body weight (BW) was 76.1±14.5 kg, and African Americans was 23.6%. Blood urea nitrogen (BUN) was 12.6±4.7 mg/dL; SCr was 0.89±0.34 mg/dL. As spot urine Cr and osmolality were 127.1±84.0 mg/dl and 649±266 mOsm/kg, respectively, sUCr/Osm was 0.19±0.08. With adjustment of factors related to personal urinary excretion of Cr and osmoles by multivariable regression analysis, the estimated sUCr/Osm (esUCr/Osm) for an individual was 0.153×age in year−0.070×BW in kg0.283×1.244 if African American×BUN in mg/dL−0.310×SCr in mg/dL0.681. The index of sUCr/Osm to personalized esUCr/Osm was 1.05±0.39. When only low urinary excretion of Cr is likely to be of clinical concern, further analysis showed 157 individuals (4.7%, outside the 5th percentile) had their original sUCr/Osm<0.08; 157 had the sUCr/Osm indexed for personalized esUCr/Osm<0.50.

Abstract	Non-alcoholic fatty liver disease (NAFLD) is a chronic liver disease caused by oxidative stress, inflammation and lipid deposition within liver cells, and is subsequently contributing to cardiovascular diseases such as atherosclerosis. Deep sea water (DSW) is characterized by its clearance and abundant nutrients with antioxidant and anti-inflammatory activity to confer therapeutic potential. We aimed to explore the therapeutic capability of our prepared multi-filtration DSW-dissolved organic matter (DSW-DOM) on high-fat diet-induced hyperlipidemia and endothelial dysfunction in hamsters. A high-fat/high-cholesterol diet led to increased oxidative stress, including blood reactive oxygen species (ROS), plasma malondialdehyde (MDA) and hepatic CYP2E1 expression; an increased hyperlipidemic profile and SREBP 1-mediated fatty liver; promoted NFκB p65-mediated hepatic inflammation; triggered PARP-mediated hepatic apoptosis; and enhanced endothelial intercellular adhesion molecule-1 (ICAM-1) and von Willebrand factor (VWF)-mediated atherosclerosis associated with the depressed hepatic antioxidant Paraoxonase 1 (PON1) expression. The DSW-DOM-enriched 1295 fraction, with strong H 2 O 2 scavenging activity, efficiently reduced several oxidative stress parameters, the lipid profile, inflammation, and apoptosis, possibly through the PON1-mediated antioxidant capability. Furthermore, DSW-DOM treatment significantly decreased the endothelial ICAM-1 and VWF expression, subsequently leading to the elongation of time to occlusion of FeCl 3 -induced arterial thrombosis and to the inhibition of FeCl 3 -induced fluorescent platelet adhesion to mesentery arterioles in the high-fat diet. Based on the above results, our data suggest that DSW-DOM intake via antioxidant defense mechanisms confers protective effects against high-fat diet-enhanced, oxidative stress-mediated hyperlipidemia, and endothelial dysfunction evoked atherosclerosis by downregulating oxidative injury, lipogenesis, inflammation and apoptosis.

Abstract	(1) Background: We established a new bladder ischemia rat model through bilateral partial iliac arterial occlusion (BPAO) and investigated the therapeutic effect of adipose-derived stem cells (ADSCs) and ADSC-derived microvesicles (MVs); (2) Methods: The study included four groups: (1) sham, (2) BPAO, (3) BPAO + ADSCs, and (4) BPAO + ADSC-derived MVs. Female Wistar rats with BPAO were injected with ADSCs or ADSC-derived MVs through the femoral artery. Doppler flowmetry and real-time laser speckle contrast imaging were performed to quantify blood flow in the common iliac arteries and bladder microcirculation. A 24-h behavior study and transcystometrogram were conducted after 2 weeks. Bladder histology, immunostaining, and lipid peroxidation assay were performed. The expressions of P2X2, P2X3, M2, and M3 receptors and nerve growth factor (NGF) were evaluated; (3) Results: BPAO significantly reduced bladder microcirculation, intercontraction interval (ICI), and bladder volume and increased the amplitude of nonvoiding contraction, neutrophil infiltration, and malondialdehyde and NGF levels. ADSCs and ADSC-derived MVs significantly ameliorated these effects. The results of Western blot showed that the BPAO group exhibited the highest expression of M3 and P2X2 receptors. ADSCs significantly attenuated the expressions of M2 and P2X2 receptors. ADSC-derived MVs significantly attenuated the expressions of M3 and P2X2 receptors; (4) Conclusions: ADSCs and ADSC-derived MVs ameliorated the adverse effects of BPAO including bladder overactivity, bladder ischemia, and oxidative stress. Inflammation, muscarinic signaling, purinergic signaling, and NGF might be involved in the therapeutic mechanism.

Abstract	Nutritional strategies to reduce hyperlipidemia and the risk of cardiovascular disease are gaining more public favor and medical professionals’ attention. The authors of this study explored the effect of sweet potato leaf powder (SPLP) feeding on the parameters of plasma lipids, reactive oxygen species, and time to thrombosis formation in Syrian hamsters fed with high-cholesterol diets. The animals were separated into six groups: a feeding control diet, a control diet containing 0.1% cholesterol, a control diet containing 0.2% cholesterol, a control diet containing 0.1% cholesterol plus 2.5% SPLP, a control diet containing 0.1% cholesterol plus 5% SPLP, and a control diet containing 0.2% cholesterol plus 5% SPLP for six weeks. The levels of serum total cholesterol (51% increase), low-density lipoprotein cholesterol (70.6% increase), very-low-density lipoprotein cholesterol (51.3% increase), and the triglyceride and atherogenic index (LDL-C/HDL-C) significantly increased in the high-cholesterol diet groups. Concomitant 5% sweet potato leaf powder ingestion significantly decreased the lipid profiles, with a 20.6% total cholesterol reduction in the 0.1% cholesterol diet groups, a 17.2% reduction in the 0.2% group, a 48.7% LDL reduction in the 0.1% cholesterol group, and a 30.3% reduction in the 0.2% group, with a consequent decrease in the atherogenic index. SPLP feeding was found to be associated with increased fecal sterol contents, with a 188.6% increase in the 0.1% cholesterol-fed group and a 177.3% increase in the 0.2% group. The SPLP-fed groups had depressed ROS levels, elongated FeCl 3 -induced times to thrombosis formation, and increased liver superoxide dismutase contents and SREBP-1 protein expression. Sweet potato leaf intake could reduce plasma total cholesterol, LDL, and oxidative stress. We suggest sweet potato leaf intake as a choice of nutritional strategy for hyperlipidemia and cardiovascular disease prevention.

Abstract	We explored the effects of silicon-containing water (BT) intake on gastrointestinal function and gut microbiota. BT was obtained by pressuring tap water through silicon minerals (mullite, Al6Si2O13) column. BT decreased H2O2 chemiluminescence counts, indicating its antioxidant activity. Four weeks of BT drinking increased H2O2 scavenging activity and glutathione peroxidase activity of plasma. BT drinking did not affect the body weight but significantly reduced the weight of feces and gastrointestinal motility. BT drinking significantly suppressed pylorus ligation enhanced gastric juice secretion, gastric reactive oxygen species amount, erythrocyte extravasation, IL-1β production by infiltrating leukocyte, and lipid peroxidation within gastric mucosa. Data from 16S rRNA sequencing revealed BT drinking significantly increased beneficial flora including Ruminococcaceae UCG-005, Prevotellaceae NK3B31, Weissella paramesenteroides, Lactobacillus reuteri, and Lactobacillus murinus and decreased harmful flora including Mucispirillum, Rodentibacter, and Staphylococcus aureus. This study pioneerly provided scientific evidences for the potential effects of water-soluble forms of silicon intake on antioxidant activity, gastrointestinal function, and gut microbiota modulation.

Abstract	Exendin-4 (Ex-4) is an incretin mimetic agent approved for diabetes treatment and neuronal protection. However, the required frequent injections restrict its clinical application. We prepared Ex-4-loaded poly(d,l-lactide-co-glycolide) nanoparticles (PEx-4) and investigated their effect on cerebral ischemia/reperfusion (IR) injury associated with micturition center damage-induced cystopathy in diabetic rats. Using ten minutes of bilateral carotid artery occlusion combined with hemorrhage-induced hypotension of the IR model in streptozotocin-induced type 1 diabetic (T1DM) Wistar rats, we compared the effects of Ex-4 and PEx-4 on prefrontal cortex edema, voiding function and oxidative stress including cerebral spinal fluid (CSF) reference H 2 O 2 (RH 2 O 2 ) and HOCl (RHOCl) levels, endoplasmic reticulum (ER) stress, apoptosis, autophagy and pyroptosis signaling in brain and bladder by Western blot and immunohistochemistry. Single injection of PEx-4 displayed higher CSF antioxidant activity and a long-lasting hypoglycemic effect compared to Ex-4 in rats. T1DM and IR primarily enhanced CSF RH 2 O 2 , and pIRE-1/caspase-12/pJNK/CHOP-mediated ER stress, caspase-3/PARP-mediated apoptosis, Beclin-1/LC3B-mediated autophagy and caspase-1/IL-1β-mediated pyroptosis signaling in the damaged brains. Our data further evidenced that PEx-4 were more efficient than Ex-4 in attenuating IR-evoked prefrontal cortex edema, the impairment in micturition center and the enhanced level of CSF RH 2 O 2 and HOCl, ER stress, apoptosis, autophagy and pyroptosis parameters in the damaged brains, but had less of an effect on IR-induced voiding dysfunction in bladders of T1DM rats. In summary, PEx-4 with stronger antioxidant activity and long-lasting bioavailability may efficiently confer therapeutic efficacy to ameliorate IR-evoked brain damage through the inhibitory action on oxidative stress, ER stress, apoptosis, autophagy and pyroptosis signaling in diabetic rats.

Abstract	The urothelium displays mechano- and chemosensory functions via numerous receptors and channels. The calcium-sensing receptor (CaSR) detects extracellular calcium and modulates several physiological functions. Nonetheless, information about the expression and the role of CaSR in lower urinary tract has been absent. We aimed to determine the existence of urothelial CaSR in urinary bladder and its effect on micturition function. We utilized Western blot to confirm the expression of CaSR in bladder and used immunofluorescence to verify the location of the CaSR in the bladder urothelium via colocalization with uroplakin III A. The activation of urothelial CaSR via the CaSR agonist, AC-265347 (AC), decreased urinary bladder smooth muscle (detrusor) activity, whereas its inhibition via the CaSR antagonist, NPS-2143 hydrochloride (NPS), increased detrusor activity in in vitro myography experiments. Cystometry, bladder nerve activities recording, and bladder surface microcirculation detection were conducted to evaluate the effects of the urothelial CaSR via intravesical administrations. Intravesical AC inhibited micturition reflex, bladder afferent and efferent nerve activities, and reversed cystitis-induced bladder hyperactivity. The urothelial CaSR demonstrated a chemosensory function, and modulated micturition reflex via regulating detrusor activity. This study provided further evidence of how the urothelial CaSR mediated micturition and implicated the urothelial CaSR as a potential pharmacotherapeutic target in the intervention of bladder disorders.

Abstract	Negative air ions (NAIs) being bioactive and negative charged molecules may confer antioxidant and anti-inflammatory activity. We assessed the effect of NAIs on two inflammatory diseases in animal models including lipopolysaccharide (LPS) induced acute lung injury (ALI) and wound healing in diabetic rats. We used intra-tracheal infusion of LPS to induce ALI and made a full-thickness cutaneous wound in streptozotocin-induced diabetic female Wistar rats. We evaluated NAIs effects on reactive oxygen species amount, leukocyte infiltration, wound healing rate, western blot, and immunohistochemistry in the lungs of ALI and skin sections of wounds. Our data found NAIs exposed saline displayed higher antioxidant activity vs. non-exposed saline. NAIs exposure did not significantly affect arterial blood pressure and respiratory frequency in control and LPS treated groups. LPS increased leukocyte infiltration, caspase 3/Poly-ADP-ribose-polymerase-mediated apoptosis formation and decreased Beclin-1/LC3-II-mediated autophagy in lungs. NAIs exposure conferred pulmonary protection by depressed leukocyte infiltration and caspase 3/Poly-ADP-ribose-polymerase mediated apoptosis and enhanced LC3-II-mediated autophagy in LPS induced ALI. NAIs treatment resulted in a significantly accelerated wound closure rate, decreased erythrocyte accumulation and leukocyte infiltration mediated oxidative stress and inflammation, and upregulated expression of skin collagen, vascular endothelial growth factor receptor-2 (VEGFR-2) and factor transforming growth factor-beta 1 (TGF-β1) vs non-treated group. Based on these results, it is suggested that NAIs conferred a protection through the upregulating LC3-II-dependent autophagy mechanism and downregulating leukocyte infiltration mediated inflammation and caspase 3/Poly-ADP-ribose-polymerase signaling in the LPS-treated ALI and promoted diabetic wound healing through the enhancing skin collagen synthesis, VEGFR-2 and TGF-β1 pathways.

Abstract	Background: Hyperglycemia evoked oxidative stress contributing to diabetes (DM)-induced voiding dysfunction. We explored whether antioxidant sulforaphane,a NF-E2-related nuclear factor erythroid-2 (Nrf-2) activator, may ameliorate DM-induced bladder dysfunction. Methods: DM was induced by streptozotocin and sulforaphanewas administered before DM induction.Bladder reactive oxygen species (ROS) were determined by an ultrasensitive chemiluminescence analyzer. Mitochondrial function index mitochondrial Bax and cytosolic cytochrome c, antioxidant defense Nrf-2/HO-1, endoplasmic reticulum stress marker ATF-6/CHOP, and caspase 3/PARP were evaluated by Western blot. Results: DM increased Keap1 and reduced Nrf-2 expression, associated with increase of bladder ROS, mitochondrial Bax translocation, cytosolic cytochrome c release, ATF-6/CHOP, caspase-3/PARP in bladders which resulted in voiding dysfunction by increased intercontraction intervals and micturition duration. However, sulforaphanesignificantly increased nuclear Nrf-2/HO-1axis expression, decreased bladder ROS amount, mitochondrial Bax translocation, cytochrome c release, ATF-6/CHOP and caspase 3/PARP/apoptosis, thereby improved the voiding function by the shortened intercontraction intervals and micturition duration. Conclusion: We suggest that sulforaphanevia activating Nrf-2/HO-1 signaling preserved mitochondrial function and suppressed DM-induced ROS, endoplasmic reticulum stress, apoptosis and voiding dysfunction.
