Invitro Membrane Stabilizing Potentials Of Fractionates Of Ethanolic Extract of Carica Papaya Leaf

Invitro membrane-stabilizing potentials of fractionates of ethanolic extract of Carica Papaya leaf was investigated in this study. The soxhlet extraction method was used to extract the plant, fractionated with 6 different solvents to give 6 different fractions (hexane, ethyl acetate, chloroform, butanol, methanol benzene). Hbss red blood cells samples were obtained from non-crises state sickle cell patients from Eku Baptist hospital Abraka Delta State, Nigeria. These tests involved the use of positive (p-hydroxy benzoic acid 5ug/ml) and negative controls (normal saline) for membrane stability experiments. Hbss blood was treated with 2mg/ml to 10mg/ml in seven groups with leaf fractionates. Data was analyzed using ANOVA test. The results shows that osmotic fragility was reduced by the introduction of the leaf fractionate, with the highest rate of reduction noticed in the hexane 1 fractionate. PHBA reversal rate and osmotic fragility effect was normal at low doses, but as concentration increases, reversal rate and percentage reduction of sickling decreases. It was concluded that Carica papaya leaf extract fractions, just as its crude extracts, have as much osmotic fragility activities, and this is dose-dependent and has no negative effect on tested blood samples as compared with the treatments with PHBA.

Terlipressin for Hepatorenal Syndrome-Acute Kidney Injury in Acute-On-Chronic Liver Failure: A Single-Center Retrospective Cohort Study

Objectives: Patients with hepatorenal syndrome-acute kidney injury (HRS-AKI) based on acute-on-chronic liver failure (ACLF) have a high rate of mortality. Terlipressin combined with albumin is the first line therapy for HRS-AKI in cirrhosis, however, whether it is more effective than albumin alone in ACLF is unclear. We aimed to analyze therapeutic effects of terlipressin in these patients. Methods: A retrospective study was conducted on patients with HRS-AKI based on ACLF at Beijing You’an Hospital between October 2010 and October 2019. The primary endpoint was a reversal rate of HRS-AKI, which was defined as serum creatinine (sCr) reduced to within 0.3 mg/dL of baseline. The secondary endpoints included a reversal rate of HRS in patients with sCr<1.5mg/dL and 28-day survival. Results: 221 of 755 patients meet inclusion criteria. 113 cases were treated with terlipressin plus albumin (TA group), whereas 108 cases with albumin alone (AA group). The reversal rate of HRS-AKI in TA group was higher compared to in AA group (35.39% vs 23.15%, P = 0.046). Additionally, reversal time in TA group was 8.18 ± 4.39 days, compared to 11.29 ± 3.67 days in AA group ( P = 0.005). In patients with sCr < 1.5mg/dL, reversal rate of HRS-AKI in TA group was 41.46% (17/47) compared to 19.61% (10/51) in AA group (P = 0.067). Furthermore, reversal time in TA group was 8.12±5.75 days, compared to 9.40±2.67 days in AA group (P=0.117). Notably, 28-day overall survival and transplantation-free survival in TA group was better than AA group (P < 0.001).Conclusions: Terlipressin combined albumin was effective for HRS-AKI in ACLF. Combination therapy tends to be more beneficial for patients with sCr level <1.5 mg/dL.

Does Judicial Selection Affect Judicial Performance? Evidence from a Natural Experiment

Do judges selected by merit review commissions perform better than elected judges or those directly appointed by elected officials? This is a central question in both the academic study of state judicial institutions and the policy discourse about how to reform them. To address it, we take advantage of the variation in the means of the selection for trial court judges within Arizona, a state comprised of appointed, elected, and merit-selected trial court judges. This unique context allows us to use an objective measure of judicial performance – the reversal rate of trial court cases appealed to Arizona’s state appellate courts – to evaluate judges by their means of selection. We gather an original dataset on 2919 cases heard by 176 judges, estimating multivariate models that control for characteristics of cases and of judges. Overall, we find that elected judges have a lower reversal rate than merit-selected judges. Our findings question the conventional wisdom in the state courts literature in favor of merit selection and against judicial elections, and encourage further work on the effects of judges’ means of selection beyond state supreme courts to include state appellate and trial courts.

Jumpy and Jerky: When Peripheral Vision Faces Reverse-Phi

When an annulus in fast apparent motion reverses its contrast over time, the foveal and peripheral percepts are strikingly different. In central vision, the annulus appears to follow the same path as an annulus without flicker, whereas in the periphery, the stimulus seems to randomly jump across the screen. The illusion strength depends on motion speed and reversal rate. Our observations suggest that it results from a balance between conflicting phi and reverse-phi motion, positional uncertainty, and attention. In addition to illustrating the differences between central and peripheral motion processing, this illusion shows that both discrete positional sampling and motion energy combine to generate motion percepts, although with eccentricity dependent weights that are themselves affected by attention.

Role of Reconstructive Microsurgery in Tubal Infertility in Young Women

Aim: Here, we retrospectively analyzed the success rate of reconstructive microsurgery for tubal infertility (RMTI) as a “first-line” approach to achieving tubal reversal and pregnancy after tubal infertility. Patients and Methods: During 9 consecutive years (2005–2014), 96 patients diagnosed with obstructive tubal infertility underwent RMTI (tubal reversal, salpingostomy, and/or tubal implantation) in our centre. The outcomes are presented in terms of tubal reversal rate and pregnancy and correlated with age, level of tubal obstruction, and duration of tubal infertility. Results: The overall tubal reversal rate was 87.56% (84 patients). The 48-month cumulative pregnancy rate was 78.04% (64 patients), of which seven ectopic pregnancies occurred (8.53%). The reversibility rate for women under 35 yo was 90.47%, with a birth rate of 73.01%. The reconstruction at the infundibular segments favored higher ectopic pregnancy rates (four ectopic pregnancies for anastomosis at infundibular level—57.14%, two for ampullary level—28.57%, and one for replantation technique—14.28%), with a significant value for p < 0.05. Conclusions: In the context of IVF “industrialization”, reconstructive microsurgery for tubal infertility has become increasingly less favored. However, under available expertise and proper indication, RMTI can be successfully used to restore a woman’s ability to conceive naturally with a high postoperative pregnancy rate overall, especially in women under 35 yo.

Observing the signature of the magnetic field's behaviour in the radial variation of inner core anisotropy

&lt;p&gt;The release of latent heat and lighter materials during inner core solidification is the driving force of the liquid iron flow in the outer core which generates the Earth's magnetic field. It is well known that the behaviour of the magnetic field varies over long time scales. Two clearly identifiable regimes are recognized, (i) superchrons and (ii) periods of hyperactivity (Biggin et al. 2012). Superchrons are characterized by an exceptionally low reversal rate of the magnetic pole and are associated with a low core mantle boundary (CMB) heat flux. Hyperactive periods are defined by a high reversal rate and have a high CMB heat flux.&lt;/p&gt;&lt;p&gt;Here we investigate whether the occurrence of these two regimes is related to radial variations in inner core seismic structure. Using seismic body-wave observations of compressional PKIKP-waves (Irving &amp; Deuss 2011, Waszek &amp; Deuss 2011, Lythgoe et al. 2013)., we construct a model of inner core anisotropy by comparing the difference between travel times for polar and equatorial rays. Anisotropy is the directional dependence of wave velocity and is determined by the structure of iron crystals in the inner core, hence changes in seismic anisotropy are due to changes in inner core crystal texture. We invert for radial changes in anisotropy while allowing for lateral variations and find that a model of the inner core containing five layers best fits our data. The model contains an isotropic uppermost inner core and four deeper layers with varying degrees of anisotropy.&lt;/p&gt;&lt;p&gt;Texture differences of the inner core iron crystals have been linked to changes in the solidification process of the inner core (Bergman et al. 2005), i.e. the motor of outer core flow. Therefore, the observed anisotropy variation, caused by variations of inner core solidification, might be related to changes in the behaviour of the magnetic field. Using an inner core growth model (Buffett et al. 1996) we convert depth to time for a range of inner core nucleation ages between 3.0 and 0.5 Ga (Olsen 2016). We find a remarkable correlation between the solidification time of the seismically observed layers and the occurrence of the magnetic regimes for two inner core ages; one with a nucleation at 1.4 Ga and one at 0.6 Ga, corresponding to an average CMB heat flux of 7.6 TW and 16.7 TW respectively.&lt;/p&gt;&lt;p&gt;Although we currently cannot differentiate between these two inner core ages considering our results alone, they do show that a relation between inner core structure and the behaviour of the magnetic field is possible, and suggest that seismic observations of inner core structure might provide new and independent insights into the magnetic field and its history.&lt;/p&gt;
