The MTT assay revealed both free drug and drug loaded niosomes exhibited a dose-dependent cytotoxicity against breast cancer cells (MDA-MB-231 cells). Flow cytometry and qPCR analysis revealed drug loaded niosomes exert their cytotoxicity on cancerous cells via regulation of apoptotic and anti-apoptotic genes.

The prepared niosomal simvastatin showed good physicochemical and biological properties than free drug. Our study suggests that niosomal delivery could be considered as a promising strategy for the delivery of poor water-soluble drugs to cancer cells.

However, little research has been conducted on overcoming resistance to the process changes needed for adoption of big data technologies. In this article, we address this gap in the literature by investigating the impact of interactive data visualization on decision-making around operational process changes with big data. Our goal is to demonstrate how the choice of visualization of workflow and operational processes impacts decisions to embrace real-time, big data technology. To do so, we conduct a case study of patient/provider interactions in a large health care practice and compare the initial state with a revised workflow using a big data, real-time analytics platform. AZD2171 in vitro We then investigate the impact of the data visualization strategy on decision-making to implement operational changes caused by big data. The study demonstrates that interactive data visualization of operational processes can be an enabler in overcoming organizational resistance to big data technologies in a change-resistant organization. The concomitant benefit is that big data analytics is placed directly into the hands of primary decision makers.Rhinophyma is a skin condition that affects the nose. It is often characterised by a large, red, bulbous nose. It can have a physical, psychological and social impact on the patient. Management options include conservative medical therapy such as retinoids or surgical excision followed by reconstruction as required. The reconstruction options can range from a dermal substitute full-thickness skin graft to local flaps, depending on the wound bed. We present a severe case of rhinophyma that required a complex reconstruction with a three-stage forehead flap because of the mass effect and the wound that resulted from the surgical excision of an extremely large and troublesome rhinophyma.Congenital cataract refers to a lens opacity caused by multiple etiological factors, including genetic mutation, abnormal metabolism of the lens, and infection. Currently, there are >100 known disease-causing genes as well as 60 known mutations in the Cx46 gene (Gap junction alpha-3, GJA3) associated with congenital cataracts. Dysfunction of gap junctions impairs homeostasis in lens cells, thereby inducing cataract pathogenesis. This study aims to identify the disease-causing mutation in a family with congenital cataract, and to further explore the possible pathogenic mechanism resulting from this mutation. We identified that a recurrent heterozygous missense mutation c.T148C (p.S50P) in GJA3 was the pathogenic mutation in this family. Previously, this mutation was found in a British family causing bilateral congenital cataract. We further demonstrated that CX46 wild type (WT) was coupled through functional gap junctions in HeLa cells, while mutant Cx46 S50P lost this ability. Moreover, the half-life of Cx46 S50P was longer than that of Cx46 WT, Cx46 S50P protein was also localized to the endoplasmic reticulum and induced more reactive oxygen species compared to Cx46 WT, which may lead to dysregulation of Cx46-formed gap junction. Collectively, our study defines the genetics basis of a congenital cataract family as well as the cellular mechanisms of mutant Cx46 S50P, and provides useful information for further studies of the pathogenesis and therapeutic strategy for treating congenital cataract.Aim To determine whether pretreatment of neutrophil-to-lymphocyte ratio (NLR) or platelet-to-lymphocyte ratio (PLR) has a prognostic value in patients with inoperable locally advanced non-small-cell lung cancer. Materials & methods A total of 167 patients between 2013 and 2016 were analyzed retrospectively. Results Appropriate cut-off values for initial NLR (3.06) and PLR (168.03) were determined by receiver operating characteristic curves. High NLR (p less then 0.001 and p less then 0.001) was related to poor overall survival (OS) and progression-free survival (PFS) via univariate analysis. Multivariable analysis showed that NLR can independently influence OS (hazard ratio 1.570; p = 0.012) and PFS (hazard ratio 1.471; p = 0.023). PLR did not correlate with OS or PFS. Conclusion Pretreatment of NLR could independently predict the prognosis of inoperable locally advanced non-small-cell lung cancer patients, while pretreatment of PLR does not have prognostic value.

Studies have demonstrated the diagnostic efficiency of antibody testing in COVID-19 infection. There is limited data on the IgM/IgG changes in asymptomatic and discharged patients with reoccurring positive nucleic acid test (RPNAT). This study aims to investigate these IgM/IgG changes.

There were 111 patients with positive nucleic acid test (NAT) and 40 suspected patients enrolled in the study. The serum SARS-CoV-2 specific IgM/IgG antibody levels were retrospectively analysed with the disease progress in asymptomatic and RPNAT patients.

The best overall performance was found by combining the IgM, IgG, and CT; 95.1% sensitivity and 75% specificity. This was tested in 111 RT-PCR positive cases. The median IgM and IgG levels were lower in the asymptomatic group compared to the symptomatic group (

 < .01). Among 15 RPNAT cases, the IgM levels of the RPNAT group at the time of discharge (IgM2.79, IQR 0.95-5.37) and retest (IgM 2.35, IQR 0.88-8.65) were significantly higher than those of the non-reoccurring positive nucleic acid test group (Non-RPNAT) (IgM on discharge 0.
