Effect of Hypertonic Versus Isotonic Saline Resuscitation on Heme Oxygenase-1 Expression in Visceral Organs Following Hemorrhagic Shock in Rats

To compare the early effects of hypertonic and isotonic saline resuscitation on heme oxygenase-1 （HO-1） expression in organs of rats with hemorrhagic shock. Rats were randomly divided into hypertonic saline resuscitation （HTS）, normal saline resuscitation （NS） and sham groups. HO-1 mRNA, protein expression and apoptosis were evaluated in organs. In the HTS group, significant difference was noted in HO-1 protein in small intestinal mucosa and liver compared with the NS and sham groups, and in HO-1 mRNA in liver and kidney compared with the sham group. The apoptosis of small intestinal mucosa, liver, heart, and lung was significantly lower in the HTS group than that in the NS group. In this study, small volume resuscitation with HTS can efficiently up-regulate the expression level of HO-1 in small intestinal mucosa and liver, which may be one of the mechanisms alleviating organ damage.

Efficacy of Isotonic Seawater Solution on Inflammation of the Ocular Surface in Matrix Metalloproteinase MMP-9-Positive Dry Eye Disease Patients

Purpose: Prospective study to evaluate the anti-inflammatory efficacy of isotonic seawater solution on metalloproteinase 9 (MMP-9) levels in the tears of patients with dry eye disease (DED). Methods: A total of 50 patients were included, with the following dry eye criteria in both eyes: InflammaDry? test initially positive, ocular surface disease index (OSDI) score ≥ 12 and <33, tear film breakup time (TBUT) ≤ 10 seconds, Shirmer I test result ≤ 10 mm/5 minutes, corneal staining ≥ 1. Additionally, all the patients selected corresponded to a dry eye type 2 - 3 severity degree - mild and moderate - Dry Eye Workshop Study (DEWS) classification. The InflammaDry test is used to measure levels of MMP9 at the beginning and the end of the study. All patients were treated exclusively with isotonic seawater solution 5 times a day for 3 weeks. Results: The InflammaDry test was positive in 100% of the patients (n = 50) and in 100% (n = 100) of the eyes before treatment. In 14 (28%) patients the test became negative in both eyes, and in 15 (30%) it was negative in one of the eyes. In 43% (n = 43) of the positive eyes, MMP-9 became undetectable in the tear fluid following treatment with isotonic seawater. This change was statistically significant (p < 0.001). Conclusions: The washes with ophthalmic isotonic seawater solution have a significant impact on inflammation of the ocular surface in dry eye disease, with an ability to make MMP-9 levels negative in 43% of cases.

The Effect of Isometric and Isotonic Exercises of Lower Limbs Extensor Sling on Static and Dynamic Balance in Basketball Players with Patellofemoral Pain

Background: Patellofemoral Pain Syndrome (PFPS) is one of the most common conditions among athletes. Although there are various causes for this condition, reduced balance is the problem most frequently expressed by these patients. The aim of the present study was to examine the effect of Extensor Muscle Sling Isometric and Isotonic (EMSII) exercises of lower limbs on female basketball players suffering from PFPS. Method: A total of 30 participants, all female basketball players suffering from PFPS, with an average age of 20 - 30 years, were divided into two isometric/isotonic and control experimental groups. Eight weeks of isometric and isotonic exercises were recommended to the participants with a focus on EMSII exercises of lower limbs in two four-week phases. The control group received no specific exercise program. Pre-test and post-test included the use of Stork balance test (SBT) and Y Balance tests (YBT) to assess the static and dynamic balance, respectively. Results: After eight weeks of performing separate isometric and isotonic exercises on the mentioned muscles, and according to the results of the pre-test, a significant increase was observed in the results of both static and dynamic balance tests (P Conclusion: EMSII exercises of lower limbs showed a significant effect on the increased balance. Recommended exercises can be suggested according to the type of exercises as a factor for increasing static and dynamic balance.

On the Behavior of Connectedness Properties in Isotonic Spaces under Perfect Mappings

The topological study of connectedness is heavily geometric or visual. Connectedness and connectedness-like properties play an important role in most topological characterization theorems, as well as in the study of obstructions to the extension of functions. In this paper, the behaviour of these properties in the realm of closure spaces is investigated using the class of perfect mappings. A perfect mapping is a type of map under which the image generally inherits the properties of the mapped space. It turns out that the general behaviour of connectedness properties in topological spaces extends to the class of isotone space.

Quadratic Loss of Isotonic Normal Means under Simultaneous Order Restrictions

For two normal populations with unknown means μ and unknown variances σ2, assume that there are simple order restrictions among the means and variances: μ1 < μ2 and σ12 >σ22 > 0. This case is said to be simultaneous order restriction by Shi (Maximum likelihood estimation of means and variances from normal populations under simultaneous order restrictions, J. Multivariate Anal., 50(1994), 282-293.) and an iterative algorithm of computing the order restricted maximum likelihood estimates of μi and σi2 was given in that paper. This paper shows that the restricted maximum likelihood estimate of μi has smaller mean square loss than the usual estimate xi under some conditions.

Isotopic Ratio, Isotonic Ratio, Isobaric Ratio and Shannon Information Uncertainty

The isoscaling and the isobaric yield ratio difference(IBD) probes, both of which are constructed by yield ratio of fragment, provide cancelation of parameters. The information entropy theory is introduced to explain the physical meaning of the isoscaling and IBD probes. The similarity between the isoscaling and IBD results is found, i.e.,the information uncertainty determined by the IBD method equals to β- α determined by the isoscaling(α(β) is the parameter fitted from the isotopic(isotonic) yield ratio).

Corneal collagen crosslinking in patients treated with dextran versus isotonic hydroxypropyl methylcellulose (HPMC) riboflavin solution: a retrospective analysis

Background:Corneal collagen crosslinking(CXL)is a widely used treatment for halting the progression of keratoconus.Although initial studies of CXL were performed with a riboflavin solution containing dextran,recent protocols for CXL have indicated the use of a riboflavin solution containing isotonic hydroxypropyl methylcellulose(HPMC).This study was performed to investigate differences in visual outcomes and Scheimpflug(Pentacam)analysis in patients who have undergone epithelium-off CXL with riboflavin solution containing either 20%dextran versus 1.1%HPMC.Methods:All patients in this non-randomized,non-masked,retrospective cohort analysis were treated at Edward S.Harkness Eye Institute,Columbia University Medical Center,New York,NY,USA.Thirty-seven eyes of 33 patients were crosslinked with a dextran solution and 19 eyes of 19 patients crosslinked with an isotonic HPMC solution,both using an epithelium-off 30-min,3 mW/cm2 protocol.All patients had a diagnosis of keratoconus or postrefractive surgery ectasia.Best spectacle corrected visual acuity(BSCVA)and Pentacam parameters were compared at all follow up visits(1,6,12,and 24 months).Differences between groups treated with HPMC and dextran were compared using student’s t-test.Differences between treated eye and fellow eye were calculated and compared between HPMC and dextran groups using paired t-test.Results:Patients treated with a dextran solution had significantly greater improvement in BSCVA at 1,6,and 24 months(p<0.05)compared to the isotonic HPMC-treated group.Kmax increased in both groups at 1 month;however,HPMC-treated patients had a greater increase compared to dextran-treated patients(p=0.01).Kmax decreased in both groups at 6 and 12 months,although this finding was only significant in the HPMC-treated group at 12 months.Conclusions:Our data suggest that crosslinking with the dextran solution may result in significantly better visual outcomes(demonstrated by visual acuity)compared to the isotonic HPMC riboflavin solution.Dextran solutions may have other potential advantages intrinsic to its biochemical properties facilitating more efficient crosslinking.Further research and long-term evidence regarding the use of dextran versus HPMC riboflavin solutions in collagen crosslinking is necessary.

Comparison of isotonic and hypotonic contrast agent in inducing contrast induced nephropathy after percutaneous coronary intervention

Background The incidence of contrast induced nephropathy （CIN） is increasing while patients are more and more frequently undertaking coronary angiography and percutaneous coronary intervention （PCI）. CIN correlates with the later cardiovascular events, the rising mortality risks and the increasing one-year target vessel revascularization. At present, few articles reported on whether the incidence of CIN induced by isotonic and hypotonic contrast agent after PCI is different or not. Objectives To investigate the different effect of isotonic and hypotonic contrast agent in inducing CIN in patients with coronary artery disease after PCI. Methods We enrolled 355 patients with coronary artery disease who undertook PCI from January 2007 to December 2008 as subjects. Renal functions of all 355 patients were normal. Patients were randomly divided into isotonic group and hypotonic group. Concentrations of serum creatinine （SCr） were measured before, 48～72 hours and 7 days （if needed） after PCI. The glomerular filtration rate （eGFR） was calculated according to MDRD formula. The incidence of CIN was defined as the concentration of SCr ≥0.5 mg/dL（44.2 μmol/L）. Hemodialysis rates and mortality were recorded in the hospital. Results There was no significant difference in the basline eGFR （79.52±5.28 vs 81.03±6.09, P0.05）, dosages of contrast agent （125.68±15.88 mL vs 123.51±16.38 mL, P0.05）, eGFR of 48-72 hours after PCI （70.26±9.48 vs 69.06±9.59, P0.05） and incidences of CIN （5.56% vs 5.78%, P0.05） between the two groups. eGFR and concentrations of SCr 7 days after PCI showed no significant difference between the two groups （P0.05）. No patient was dead or needed hemodialysis in hospital. Conclusions The effect of isotonic and hypotonic contrast agent in inducing CIN in patients with coronary artery disease after PCI has no difference.

Description of the evolution of mixed-symmetry states in the N=78 isotonic chain with IBM2

The characteristics of the lowest mixed-symmetry states 2＋msand 1＋ms for132Xe,134 Ba and136Ce in the even-even N = 78 isotones are investigated within the framework of the IBM2 model. The lowest mixed-symmetry state 2＋mslevels for both a single isolated state in132 Xe and136Ce and a fragmented state in134 Ba are reproduced by the predictions. The agreement between the IBM2 calculation and the experimental values is good for the B（E2）and B（M1） transition probabilities both quantitatively and qualitatively. The predicted summed B（M1） strength follows the experimental data, remaining nearly constant as a function of proton number along the chain of the N =78isotones.

Jonzac Thermal Spring Water Reinforces Skin Barrier Function of Human Skin and Presents a Soothing and Regenerating Effect

The skin is a formidable physical and biological barrier which communicates continuously with the outside of the body. And the stratum corneum, the outermost layer of human epidermis, plays a central role in the interaction between the cutaneous tissue and the external environment. The horny layer, and more generally the whole skin layers, avoid the penetration of harmful exogenous agents, produce molecules named anti-microbial peptides which impact the composition of the cutaneous microbiota, regulate the internal corporal temperature, avoid the water loss from the inside of the body and constitute an incredible efficient anti-oxidant network. Nevertheless, nowadays, the skin is more and more solicited by the different elements of the cutaneous exposome, including atmospheric pollution and solar radiations, which can cause a dramatic acceleration of the skin ageing process. As a consequence, due to the multifunctional protective role of the skin, during the recent decade the cosmetic industry invested massively in the development of new raw materials and end-products (dermo-cosmetics) able to preserve an optimal state of the skin regarding the external environment. Based on their physical-chemical properties thermal spring waters, which are extremely rich in inorganics ions, are interesting and powerful candidates to be part, as integral component, of new efficient dermo-cosmetic formulations dedicated to protect the skin from the external stimuli. The aim of the present work was to investigate and characterize the activity of Jonzac thermal spring water on the skin. Using different models, we proved for the first time that Jonzac thermal spring water reinforces the barrier function of the skin by modulating the expression of key markers including filaggrin and human beta defensin 2 on ex vivo human skin. The ex vivo and in vivo hydration activity, by Raman spectroscopy and corneometry respectively, has been also demonstrated. We have also shown that Jonzac thermal spring water ameliorates significantly the cutaneous microrelief in vivo. To conclude, we characterize the soothing effect of Jonzac thermal spring water by the analysis of histamine release in Substance P treated skin explants and by measuring the redness of the skin following UV exposure of the skin in vivo. We observed that both parameters decreased following a preventive treatment of the skin with Jonzac thermal spring water. Taken together our results indicate that Jonzac thermal spring water is a promising and powerful dermo-cosmetic which can be used to preserve an optimal state of the cutaneous tissue.

An Non-parametrical Approach to Estimate Location Parameters under Simple Order

This paper deals with estimating parameters under simple order when samples come from location models. Based on the idea of Hodges and Lehmann estimator (H-L estimator), a new approach to estimate parameters is proposed, which is difference with the classical L1 isotonic regression and L2 isotonic regression. An algorithm to compute estimators is given. Simulations by the Monte-Carlo method is applied to compare the likelihood functions with respect to L1 estimators and weighted isotonic H-L estimators.

On Pseudo-Category of Quasi-Isotone Spaces

Recent developments in mathematics have in a sense organized objects of study into categories, where properties of mathematical systems can be unified and simplified through presentation of diagrams with arrows. A category is an algebraic structure made up of a collection of objects linked together by morphisms. Category theory has been advanced as a more concrete foundation of mathematics as opposed to set-theoretic language. In this paper, we define a pseudo-category on the class of isotonic spaces on which the idempotent axiom of the Kuratowski closure operator is assumed.
