1942 > .05) with increase of the F doping. A significant difference was obtained the microhardness values between La3+ and F- ions co-doped HA materials and pure HA (p [.0053] less then .05). Accordingly, this study confirmed that since the La3+ and F- ions can potentially increase the efficacy of HA. According to the spectral, mechanical, and microstructure analysis result, this material can be as a good candidate product for use as an occluding material for dental application.Molecules are fascinating candidates for constructing tunable and electrically conducting devices by the assembly of either a single molecule or an ensemble of molecules between two electrical contacts followed by current-voltage (I-V) analysis, which is often termed "molecular electronics". Recently, there has been also an upsurge of interest in spin-based electronics or spintronics across the molecules, which offer additional scope to create ultrafast responsive devices with less power consumption and lower heat generation using the intrinsic spin property rather than electronic charge. Researchers have been exploring this idea of utilizing organic molecules, organometallics, coordination complexes, polymers, and biomolecules (proteins, enzymes, oligopeptides, DNA) in integrating molecular electronics and spintronics devices. Although several methods exist to prepare molecular thin-films on suitable electrodes, the electrochemical potential-driven technique has emerged as highly efficient. In this Review we describe recent advances in the electrochemical potential driven growth of nanometric various molecular films on technologically relevant substrates, including non-magnetic and magnetic electrodes to investigate the stimuli-responsive charge and spin transport phenomena.
Ripretinib 150 mg once daily (QD) is indicated for advanced gastrointestinal stromal tumors (GISTs) as at least fourth-line therapy. In INVICTUS, ripretinib intrapatient dose escalation (IPDE) to 150 mg b.i.d. was allowed after progressive disease (PD) on 150 mg QD by blinded independent central review using modified RECIST 1.1. We report the efficacy and safety of ripretinib IPDE to 150 mg b.i.d. after PD among patients randomized to ripretinib 150 mg QD in the INVICTUS study.
Tumor imaging was performed every 28-day cycle for the first four cycles in the ripretinib 150 mg QD period and then every other cycle, including the 150 mg b.i.d.
Among the ripretinib IPDE patients, progression-free survival (PFS)1 was the time from randomization until PD; PFS2 was the time from the first dose of ripretinib 150 mg b.i.d. to PD or death.
Among 43 ripretinib IPDE patients, median PFS1 was 4.6 months (95% confidence interval [CI], 2.7-6.4) and median PFS2 was 3.7 months (95% CI, 3.1-5.3). Median overall survival dicate ripretinib IPDE to 150 mg b.i.d. may provide additional clinical benefit in patients with PD on ripretinib 150 mg QD, for whom limited treatment options exist.
Of the 85 patients with advanced gastrointestinal stromal tumor having received at least three prior anticancer therapies randomized to ripretinib 150 mg once daily (QD) in the phase III INVICTUS study, 43 underwent ripretinib intrapatient dose escalation (IPDE) to 150 mg b.i.d. after progressive disease (PD). Median progression-free survival was 4.6 months before and 3.7 months after ripretinib IPDE. The safety profile of ripretinib 150 mg b.i.d. was acceptable. These findings indicate ripretinib IPDE to 150 mg b.i.d. may provide additional clinical benefit in patients with PD on ripretinib 150 mg QD, for whom limited treatment options exist.
Peritoneal dialysis (PD) as a modality of kidney replacement therapy (KRT) is largely underutilized globally. We analyzed PD utilization, impact of economic status, projected growth and impact of state policy(s) on PD growth in South Asia and Southeast Asia (SA&SEA) region.
The National Nephrology Societies of the region responded to a questionnaire on KRT practices. The responses were based on the latest registry data, acceptable community-based studies and societal perceptions. The representative countries were divided into high income and higher-middle income (HI & HMI) and low income and lower-middle income (LI & LMI) groups.
Data provided by 15 countries showed almost similar percentage of GDP as health expenditure (4%-7%). But there was a significant difference in per capita income (HI & HMI -US$ 28 129 vs. LI & LMI - US$ 1710.2) between the groups. Even after having no significant difference in monthly cost of haemodialysis (HD) and PD in LI & LMI countries, they have poorer PD utilization as compared to HI & HMI countries (3.4% vs. Rapamycin 10.1%); the reason being lack of formal training/incentives and time constraints for the nephrologist while lack of reimbursement and poor general awareness of modalities has been a snag for the patients. The region expects ≥10% PD growth in the near future. Hong Kong and Thailand with 'PD first' policy have the highest PD utilization.
Important deterrents to PD underutilization were lack of PD centric policies, lackadaisical patient/physician's attitude, lack of structured patient awareness programs, formal training programs and affordability.

To present the findings of a systematic review on reported quality of life following the formation of a urinary diversion as a result of cystectomy due to urinary bladder neoplasm.
Bladder cancer is the most commonly occurring cancer of the urological system. Treatment often involves undergoing a radical cystectomy with an ileal conduit formation. Quality of life issues associated with this surgery are complex and varied.
A systematic review using thematic synthesis.
A comprehensive search, using The Cochrane Library, CINAHL, PubMed and PsycInfo databases, focusing on the years from 2007 to 2020.
The Preferred Reporting Items for Systematic Reviews and Meta-Analyses was the chosen checklist used. Studies were critically appraised using the Crowe Critical Appraisal Tool.
The formation of an ileal conduit negatively affects respondent's quality of life particularly regarding body image, social distress, reduced sexual activity and employment. Poor research focus on the impact of ileal conduit formation on sexual well-being postoperatively was apparent.
Further research using qualitative methodologies is needed to gain a deeper understanding of how this life-changing procedure impacts quality of life.

Recent studies show that the catalytic efficiency of MoS2 for HER can be promoted by the presence of 1T-phase MoS2 . It is hard to precisely control the formation of 1T-MoS2 , however, due to its metastability relative to 2H-MoS2 . Elevating the stability of 1T phase allotrope is therefore of great importance and could be realized by replacing divalent S with monovalent elements or groups according to crystal field theory, which has been demonstrated through our first-principles density functional theory (DFT) calculation results. Differential Gibbs free energy analysis for hydrogen adsorption (ΔGH* ) suggest that 1T and 1T' MoSO (O doped MoS2 ) might be taken as potential candidate catalysts for HER process with better performance than 1T and 1T' MoS2 . We also propose a probable approach to synthesize 1T and 1T' MoSO under oxidation circumstance environment of graphene oxide.Secondary ligand-metal interactions are decisive in many catalytic transformations. While arene-gold interactions have repeatedly been reported as critical structural feature in many high-performance gold catalysts, we herein report that these interactions can also be replaced by Au⋅⋅⋅H-C hydrogen bonds without suffering any reduction in catalytic performance. Systematic experimental and computational studies on a series of ylide-substituted phosphines featuring either a PPh3 (Ph YPhos) or PCy3 (Cy YPhos) moiety showed that the arene-gold interaction in the aryl-substituted compounds is efficiently compensated by the formation of Au⋅⋅⋅H-C hydrogen bonds. The strongest interaction is found with the C-H moiety next to the onium center, which due to the polarization results in remarkably strong interactions with the shortest Au⋅⋅⋅H-C hydrogen bonds reported to date. Calorimetric studies on the formation of the gold complexes further confirmed that the Ph YPhos and Cy YPhos ligands form similarly stable complexes. Consequently, both ligands showed the same catalytic performance in the hydroamination, hydrophenoxylation and hydrocarboxylation of alkynes, thus demonstrating that Au⋅⋅⋅H-C hydrogen bonds are equally suited for the generation of highly effective gold catalysts than gold-arene interactions. The generality of this observation was confirmed by a comparative study between a biaryl phosphine ligand and its cyclohexyl-substituted derivative, which again showed identical catalytic performance. These observations clearly support Au⋅⋅⋅H-C hydrogen bonds as fundamental secondary interactions in gold catalysts, thus further increasing the number of design elements that can be used for future catalyst construction.
The aim of this study was to determine the effect of a lifestyle training package that consisted of a 60- to 90-min session of group training, educational booklet and text messages on physical activity and nutritional status in obese and overweight pregnant women.
In this randomized controlled trial, 140 obese or overweight women (gestational age 16-20 weeks) covered by health centres in Tehran, Iran, were equally randomized into two parallel groups using block randomization and stratified by the body mass index. Participants completed the Food Frequency Questionnaire and International Physical Activity Questionnaire at baseline and fourth and eighth weeks after intervention. Participants were 38 obese and 102 overweight women who were later followed-up.
After the intervention, the mean weekly intake of the vegetable and fruit subgroups was significantly higher; and intake of fats and oils and the confections subgroups were significantly lower in the intervention compared with the control group (p < 0.05). Although physical activity was higher in the intervention group, 8weeks after the intervention, this difference was not statistically significant (p > 0.05).
The training package appears to offer a suitable strategy for adjusting the intake of the recommended food subgroups in obese and overweight pregnant women.
