Effectiveness of in-office tooth whitening therapy with different service methods on teeth color adjustments as well as level of sensitivity: Any randomized medical study.
The three themes emerged from 15 sub-themes. Our findings emphasized that young adults with CP faced psychosocial challenges in social relationships, participation in education and work settings and striving towards independence. The transition to young adulthood led to a series of new challenges that the young adults were not prepared for. Medical challenges included managing CP-related physical and cognitive symptoms and navigating adult health care services, where new physicians with insufficient knowledge regarding CP were encountered. Conclusion The young adults with CP were not prepared for the challenges and changes they faced during their transition into adulthood. They felt that they had been abandoned by the healthcare system and lacked a medical home. Better transitional care is urgently needed to prepare them for the challenges in young adulthood.Background Despite recognition of the important role of health workers in providing adolescent-friendly sexual and reproductive health services (AFSRHS), evidence on strategies for improving performance is limited. This review sought to address (1) which interventions are used to improve health worker performance in delivering AFSRHS? and (2) how effective are these interventions in improving AFSRHS health worker performance and client outcomes? Methods Building on a 2015 review, a search for literature on 18 previously identified programs was conducted to identify updated literature and data relevant to this review. Data was systematically extracted and analyzed. Results Due to the parent review's eligibility criteria, all programs included health worker training. Otherwise, supervision was the most frequently reported intervention used (n=10). Components and methods related to quality of trainings and supervision varied considerably in program reports. Nearly half of programs described employing processes timprove health worker performance in delivering AFSRHS. The findings indicate a need for additional effectiveness and cost-effectiveness evaluations of such interventions. In the meantime, existing evidence on improving health worker performance within and outside adolescent health must be integrated more thoughtfully into program planning and implementation.Objectives Repeated exposure to anoxic stress damages the brain through cortisol-mediated increases in oxidative stress and cellular-antioxidants depletion. Thus, compounds with antioxidant property might confer protection against anoxic stress-induced brain injuries. In this study, we further examined the protective effect of methyl jasmonate (MJ), a potent anti-stress agent against anoxic stress-induced convulsions in mice. Methods Thirty-six male Swiss mice randomized into six groups (n=6) were given MJ (25, 50 and 100 mg/kg, i.p.) or vehicle (10 mL/kg, i.p.) 30 min before 15 min daily exposure to anoxic stress for 7 days. The latency(s) to anoxic convulsion was recorded on day 7. The blood glucose and serum corticosterone levels were measured afterwards. The brains were also processed for the determination of malondialdehyde, nitrite, and glutathione levels. Results Methyl jasmonate (MJ) delayed the latency to anoxic convulsion and reduced the blood glucose and serum corticosterone levels. The increased malondialdehyde and nitrite contents accompanied by decreased glutathione concentrations in mice with anoxic stress were significantly attenuated by MJ. Conclusions These findings further showed that MJ possesses anti-stress property via mechanisms relating to the reduction of serum contents of corticosterone and normalization of brain biomarker levels of oxidative stress in mice with anoxic stress.Objectives For revealing the peculiarities of the drug-drug interaction of rivaroxaban (substrate CYP3A4 and P-gp) and calcium channel blockers (CCBs) (verapamil - inhibitor CYP3A4 and P-gp and amlodipine - substrate CYP3A4) in patients 80 years and older with nonvalvular atrial fibrillation (NAF) we studied 128 patients. Methods All patients were divided into groups depending on the therapy taken the 1st - rivaroxaban + amlodipine (n=51), the 2nd - rivaroxaban + verapamil (n=30), the control group - rivaroxaban without CCBs (n=47). A trough steady-state plasma concentration (C min,ss) of rivaroxaban, prothrombin time (PT) in the blood plasma and the event of clinically relevant non-major (CRNM) bleeding were assessed for each patient. Results Patient in group 2 had higher C min,ss of rivaroxaban, PT and CRNM than subjects in the control group (Me 73.8 [50.6-108.8] ng/mL vs. 40.5 [25.6-74.3] ng/mL; Me 14.8 [13.4-17.3] s vs. 13.8 [12.6-14.4] s; 34% vs. 13%, respectively, p0.05 for all). Conclusions In patients ≥80 years with NAF, the use of rivaroxaban in combination with verapamil may not be safe and can lead to CRNM bleeding.Objectives Oncological diseases are an urgent medical and social problem. The chemotherapy induces not only the death of the tumor cells but also contributes to the development of their multidrug resistance and death of the healthy cells and tissues. In this regard, the search for the new pharmacological substances with anticancer activity against drug-resistant tumors is of utmost importance. In the present study we primarily investigated the correlation between the expression of TrkA and p75 receptors with the nerve growth factor (NGF) and cisplatin or temozolomide sensitivity of anaplastic astrocytoma (AA), glioblastoma (GB) and medulloblastoma (MB) cell cultures. We then evaluated the changing of copy numbers of MYCC and MYCN and its correlation with cytotoxicity index (CI) in MB cells under NGF exposition. Methods The primary cell cultures were obtained from the tumor biopsy samples of the patients with AA (n=5), GB (n=7) or MB (n=25) prior to radiotherapy and chemotherapy. The cytotoxicity effect of NGF) and its correlation with CI of NGF and its combinations in AA and GB cells point to the mechanism involving a cell death signaling pathway. NGF downregulates (p less then 0.05) some increased copy numbers of MYCC and MYCN in the human MB cell cultures, and upregulates normal two copies of both oncogenes (p less then 0.05).Lysosomes contains numerous enzymes and proteins closely linked with cellular metabolism. The variation of lysosomal pH is closely related to cell homeostasis while hydrogen sulfide (H2S) has been regarded as an important gasotransmitter. Herein, via rational design, a high-sensitivity fluorescent probe ANp-Rh-Lys was synthesized for logical detection and bioimaging of H2S and pH in lysosomes of living cells. The probe showed different fluorescence signals towards H2S and lysosomal pH. Significantly, ANp-Rh-Lys is membrane-permeable and suitable for visualization of both pH variations and endogenous H2S in lysosomes. This logical design strategy may have great potential for detection of multiple analytes in complicated biological systems.Topochemical assembly carbon materials with unique structure rarely investigated and reported. Herein, we demonstrate the feasibility of using topochemical assembly levodopa nanoparticles with dendritic structure (LNDS) network as a new high-performance biosensing platform based on noncovalent functionalization of LNDS with a fluorescent oligonucleotide. The proposed platform is dependent on the competition of π-π stacking and electrostatic repulsion interactions between LNDS and fluorescent oligonucleotide. The obtained LNDS with 96.1% quenching efficiency is synthesized by using levodopa as the single precursor by natural oxidation or microwave irradiation. The constructed platform can be used for simple and efficient probing single-nucleotide polymorphisms (SNPs) and cDNA by fluorescence restoration with a highly sensitivity and selectivity, remarkably superior to those based on graphenes. Additionally, an aptasensor is further constructed for small molecule ATP detention in serum with a low detection limit of 4 μM. To the best of our knowledge, this is the first attempt to use LNDS to design a biosensing platform, and therefore opens possibilities for new types of nanoparticle-based molecule approaches, and sequencing technologies.African swine fever virus (ASFV) is a large and complex DNA virus that causes a highly contagious and often lethal swine viral disease, for which no vaccine and effective treatments are available yet. Hence, ASFV presents significant economic consequences for the swine industry. A rapid and simple diagnostic method is urgently needed to monitor ASFV-specific antibodies for controlling the spread of ASFV. In this study, we chose the truncated p54 protein as an antigen and combined it with Eu-doped fluorescent microspheres as tracers to detect anti-ASFV antibodies specifically. Results showed that the truncated p54 protein had high specificity to ASFV antibody and had no cross-reactions with other swine virus antibodies. The results between our fluorescent immunochromatography test strip (FICTS) and commercial ELISA kits showed high consistency. The proposed FICTS offers a rapid, sensitive, specific, and visual method for ASFV antibody detection and shows great potential for ASF epidemic surveillance and control.In this report, a non-toxic Dual Template Molecularly Imprinted Polymers (DMIPs) was synthesized with quercetin and schisandrin b as template molecules, using deep-eutectic solvents as functional monomers for the first time. The DMIPs were used to efficiently and simultaneously enrich quercetin and schisandrin b from the mixed crude extracts of penthorum and schisandra. The results indicated that the DMIPs exhibited rapid adsorption kinetics (80 min for adsorption equilibrium) and high selectivity. The largest adsorbing capacities to quercetin and schisandrin b were 23.58 mg/g and 41.64 mg/g, respectively. After presaturation with quercetin and schisandrin b, the nontoxic saturated DMIPs were fed to the mice. Blood samples of the mice were taken and both quercetin and schisandrin b were successfully detected. The pharmacokinetics of quercetin and schisandrin b were similar to reports in the literature where mice were directly fed with botanicals. Our study provides a reliable protocol such that DMIPs can be used to separate and enrich several target molecules simultaneously from complex biological systems. Our findings suggested that the DMIPs have potential application as a drug delivery system of compound herbal formulas.Rapid analysis of trace analytes in complex biological samples is a great challenge for direct mass spectrometry, which suffers from low detection sensitivity. In this study, molecular imprinting technology was explored on the stainless steel sheet and integrated with the electrospray ionization method for direct sample analyses. The molecularly imprinted polymer-coated stainless steel sheet (MIPCS) was prepared and used as a solid-phase microextraction tip for rapid sampling of trace fluoroquinolone antibiotics in milk samples and then applied as an electrospray ionization tip to couple MS for sensitive detection. Our results shown that MIPCS could significantly enrich the trace fluoroquinolone antibiotics in milk samples. In our study, the extraction process of milk sample was completed within 30 min and the direct MS analysis was accomplished within 1 min. In addition, this proposed MIPCS-ESI-MS method showed a good linearity (R2>0.99) ranged from 1 to 1000 ng mL-1. The limits of detection (LODs) and limits of quantitation (LOQs) for the analytes range from 0.
