Possibility and also basic safety in the successive usage of distal transradial gain access to regarding coronary angiography as well as intervention within the same supply.
We observe that the identity of the silyloxy substituent impacts the degree of planarity of the porphyrin in the solid state as well as the redox potentials.The development of earth-abundant transition-metal-based electrocatalysts with bifunctional properties (oxygen evolution reaction (OER) and hydrogen evolution reaction (HER)) is crucial to commercial hydrogen production. In this work, layered double hydroxide (LDH)-zinc oxide (ZnO) heterostructures and oxygen vacancies are constructed synchronously by plasma magnetron sputtering of NiFe-LDH. Using the optimal conditions, ZnO nanoparticles are uniformly distributed on the NiFe-LDH nanoflowers, which are prepared uniformly on the three-dimensional porous Ni foam. In the LDH-ZnO heterostructures and oxygen vacancies, electrons are depleted at the Ni cations on the NiFe-LDH surface and the active sites change from Fe cations to Ni cations during OER. Ferroptosis inhibition Our theoretical assessment confirms the change of active sites after the deposition of ZnO and reveals the charge-transfer mechanism. Owing to the significant improvement in the OER dynamics, overall water splitting can be achieved at only 1.603 V in 1 M KOH when the Ni/LDH-ZnO and Ni/LDH are used as the anode and cathode, respectively. The work reveals a novel design of self-supported catalytic electrodes for efficient water splitting and also provides insights into the surface modification of catalytic materials.
Oxidative stress has been suggested as a possible mechanism for the adverse effects of heavy metal toxicity on male reproduction. Cichorium intybus L. is used in Iranian folk medicine as a hepatoprotective agent as well as for its supposed fertility-enhancing properties. The present study was performed to investigate whether the ethanolic extract of C. intybus leaves could protect male rats against lead-induced testicular oxidative stress.

In this experimental study, adult Wistar rats were treated with 0.1% lead acetate in drinking water alone or with 50, 100, or 200 mg/ kg body weight of C. intybus extract via gavage once daily for 70 days. The weight of their reproductive organs, levels of serum hormones, histometric parameters of the seminiferous tubules, epidydimal sperm quality, and oxidative stress status were evaluated.

The testis weight, seminiferous tubule diameter, epididymal sperm count, serum testosterone level, and testicular levels of superoxide dismutase and glutathione peroxidase were significantly reduced (p<0.05) in the lead-treated rats. Moreover, significantly (p<0.05) higher levels of malondialdehyde were observed in the lead-exposed group compared to the control. However, the co-administration of C. intybus ethanolic extract in lead-treated rats was associated with a significant improvement in reproductive parameters.

We conclude that C. intybus leaf extract has the potential to prevent lead-induced testicular toxicity and to suppress the adverse effects of lead on male reproductive health.

The pathophysiological process involves fibrous inflammation of the capsule and intraarticular adhesion of synovial folds leading to capsular thickening and contracture. Regarding the multidirectional limitation of motion, a limitation in external rotation is especially prominent, which is related to not only global fibrosis but also to a localized tightness of the anterior capsule. Ultrasound and magnetic resonance imaging studies can be applied to rule out other structural lesions in the diagnosis of adhesive capsulitis. Hydraulic distension of the shoulder joint capsule provides pain relief and an immediate improvement in range of motion by directly expanding the capsule along with the infusion of steroids. However, the optimal technique for hydraulic distension is still a matter of controversy, with regards to the infusion volume and rupture of the capsule. By monitoring the real-time pressure-volume profile during hydraulic distension, the largest possible fluid volume can be infused without rupturing the capsule. The improvement in clinical outcomes is shown to be greater in capsule-preserved hydraulic distension than in capsule-ruptured distension. Moreover, repeated distension is possible, which provides additional clinical improvement. Capsule-preserved hydraulic distension with maximal volume is suggested to be an efficacious treatment option for persistent adhesive capsulitis.
The purpose of this study was to evaluate the predictive performance of OncoOVARIAN Dx algorithm, which takes into account tumor markers (beta HCG, CA 19.9, CEA, AFP, CA 125, HE4), general biochemistry and clinical data (age, menopause, comorbidities) in patients scheduled for surgical removal of a suspicious adnexal tumor in comparison with the Risk of Malignancy Algorithm (ROMA) model.

Consecutive women diagnosed with an adnexal tumor mass and scheduled for surgical intervention at a single tertiary cancer between October 2018 - June 2019 were enrolled. Preoperative values of tumor markers and general biochemistry (ASAT, ALAT, GGT, total bilirubin, creatinine) were determined. Following surgery with adequate surgical staging, a definite pathological diagnosis was made and used as reference.

A total of 50 patients were selected, including 20 benign, 5 borderline and 25 malignant epithelial ovarian cancer (EOC) cases on final pathology. Borderline tumors comprised 3 serous and 2 mucinous FIGO stage I cases. Malignant tumors included 17 high grade serous, 4 endometrioid and 4 mucinous types, FIGO stage IA-IIIC. The two models demonstrated very good correlation (Phi 0.78, p<0.001). The sensibility (Se), specificity (Sp), positive predictive value (PPV), negative predictive value (NPV) of OncoOVARIAN Dx versus ROMA model were 76.66% vs. 60%, 95% vs. 100%, 95.83% vs. 100%, 73.07% vs. 62.5%, respectively. In postmenopausal patients higher Se (85.71%), Sp (100%) and PPV (100%) were observed for OncoOVARIAN Dx.

OncoOVARIAN Dx model demonstrated higher Se and NPV compared to ROMA and could be a useful marker in the preoperative management of adnexal masses; however larger studies are warranted to validate and further refine this algorithm.
