Knockdown of 14-3-3γ by siRNA transfection markedly increased BKα expression. Blockade of the ERK1/2 pathway by incubation with the MEK-specific inhibitor U0126 partially abolished 14-3-3γ-mediated inhibition of BK protein expression. Similarly, pretreatment of the lysosomal inhibitor bafilomycin A1 reversed the inhibitory effects of 14-3-3γ on BK protein expression. Furthermore, overexpression of 14-3-3γ significantly increased BK protein ubiquitination in embryonic kidney-293 cells stably expressing BKα. Additionally, 3 days of dietary K+ challenge reduced 14-3-3γ expression and ERK1/2 phosphorylation while enhancing renal BK protein expression and K+ excretion. These data suggest that 14-3-3γ modulates BK channel activity and protein expression through an ERK1/2-mediated ubiquitin-lysosomal pathway.The male mouse is underrepresented in research of the urinary tract due to the difficulty of transurethral catheterization. As a result, there is a lack of analysis of sex differences in urinary tract research. Here, we present a novel catheter design and technique that enables urethral catheterization of male mice for bladder inoculation. Our catheterization technique uses the resistance met at the level of the external urinary sphincter and prostate to guide the retraction, positioning, and advancement of the catheter into the urinary bladder. We have shown that this method can be used to reproducibly catheterize 12 male mice with minimal urogenital trauma but cannot be used as a cystometric technique. This method will facilitate the expansion of research into sex differences in various genitourinary conditions that require transurethral catheterization of mice.Introduction A number of highly selective biologic therapies that target specific immunological pathways of psoriasis have emerged, including molecules that target interleukin (IL)-17. IL-17 has been identified as a key effector pathogenic cytokine in psoriasis, and validated as a highly effective therapeutic target for the treatment of plaque psoriasis. Area covered This review examines the therapeutic efficacy and safety of IL-17 inhibitors in plaque psoriasis and provides an overview of the efficacy and safety data of brodalumab compared with other IL-17 inhibitors. Expert opinion In the real world, the treatment of psoriasis has been revolutionized by the new class of drugs belonging to IL-17 inhibitors, with secukinumab, ixekizumab, and brodalumab currently licensed and approved for the treatment of moderate-to-severe plaque psoriasis. With its distinct mechanism of action, brodalumab may offer a unique advantage over other IL-17 inhibitors due to its rapid onset of action, achievement of complete skin clearance in a high proportion of patients, and its overall favorable safety profile. Importantly, treatment with systemic biologic drugs should be established early on in the course of the disease in order to prevent comorbidities and to allow patients to achieve a stable and persistent remission.Background Glycyrrhizic acid (GL), a pentacyclic triterpenoid glycoside, has been used as a hepatoprotective agent for the treatment of acute and chronic hepatitis. However, its poor solubility and permeability across the gastrointestinal mucosa limit its clinical efficacy. This study aimed to develop mixed micelles based on pluronic F127 and d-α-tocopheryl polyethylene glycol 1000 succinate (TPGS) to improve the oral bioavailability of GL.Methods GL loaded pluronic F127/TPGS mixed micelles (GL-F127/TPGS-MMs) were prepared by thin film hydration method, and their physicochemical properties including particle size, zeta potential, entrapment efficiency (EE), drug loading (DL), X-ray diffraction (XRD) analysis, differential scanning calorimetry (DSC), and drug release were characterized. Furthermore, the pharmacokinetic and biodistribution studies of GL-F127/TPGS-MMs were evaluated in rats and compared with GL solution.Results GL-F127/TPGS-MMs were found to be of spherical shape with particle size of (27.41 ± 4.90) nm, EE% of 95.38% and DL% of 12.99%. The results of XRD and DSC indicated that GL was encapsulated in the micelles. Drug release of GL-F127/TPGS-MMs demonstrated a sustained release behavior as compared to GL solution. The pharmacokinetic and biodistribution studies showed a significantly higher oral absorption and liver accumulation of glycyrrhetinic acid (GA) after oral administration of GL-F127/TPGS-MMs as compared to GL solution.Conclusion These results suggested F127/TPGS-MMs might be a potential nanocarrier for oral delivery of GL.Objective Previous research has found lower appearance and speech satisfaction among those with cleft lip and/or palate (CL/P) compared to noncleft control groups. Less research has been conducted into which groups report the lowest satisfaction and how these two factors relate to psychosocial difficulties. This study aimed to investigate (1) differences in appearance and speech satisfaction by diagnosis and age among young people with CL/P and (2) associations between appearance and speech satisfaction and emotional and social difficulties. Design Self-report questionnaires that had been collected between June 2016 and August 2018 within routine clinical practice were analyzed. Setting A tertiary pediatric hospital in London. Patients A total 130 nonsyndromic 10- and 15-year-old patients with CL/P. buy Entinostat Main outcome measures Cleft Hearing, Appearance and Speech Questionnaire; Strengths and Difficulties Questionnaire. Results The CLP group reported significantly lower appearance satisfaction compared to the CP group (P = .005). The 15-year-olds reported significantly lower appearance satisfaction compared to the 10-year-olds (P = .008). No significant differences were found in speech satisfaction by diagnosis (P = .06) or age (P = .064). Significant negative associations were found at 15 years old between appearance satisfaction and emotional difficulties, speech satisfaction and emotional difficulties, appearance satisfaction and social difficulties, and speech satisfaction and social difficulties (P less then .05 all correlations). Only the latter two associations were significant at 10 years old (P less then .05). Conclusions The findings have important implications as appearance and speech dissatisfaction may be ways in which to identify those at risk of psychosocial difficulties within clinical settings.
