AIM: This study was aimed at investigating the association between peri-implant maintenance therapy (PIMT) and the frequency of peri-implant diseases, and to further identify the factors that contribute to failure of PIMT compliance. MATERIAL AND METHODS: A cross-sectional study on healthy partial edentulous patients was conducted. These were grouped in the following categories according to the PIMT compliance: regular compliers (RC) (≥2 PIMT/year), erratic compliers (EC) (<2 PIMT/year), and non-compliers (NC) (0 PIMT/year)...

Patients with subjective cognitive decline (SCD) are at higher risk for conversion to dementia due to Alzheimer's disease (AD). Semantic verbal fluency (SVF) seems to be impaired in the early stages of AD. The goal of the present study was to identify the discriminative potential of verbal fluency (VF) in patients with SCD to show if very early signs of cognitive decline may be detected in SCD. We examined 93 normal controls (NC) and 61 participants with SCD. Each participant was administered a comprehensive neuropsychological battery...

In this paper, Co3O4 nanostructures with different morphologies (nanoparticles (NPs), nanosheets (NSs) and nanocubes (NCs)) are directly grown on an ITO substrate using a hydrothermal method. Sb2S3 is loaded onto Co3O4 to construct a Co3O4/Sb2S3 heterojunction, which is used as an all p-type photocathode for photoelectrochemical (PEC) water splitting for the first time. The specific morphologies of Co3O4 have been discussed in detail. The improved PEC properties of the Co3O4/Sb2S3 heterojunction are characterized...

PURPOSE: It has been increasingly suggested that specific microRNAs expression profiles in the circulation and atrial tissue are associated with the susceptibility to atrial fibrillation. Nonetheless, the role of circulating microRNAs in Graves' disease patients with atrial fibrillation has not yet been well described. The objective of the study was to identify the role of circulating microRNAs as specific biomarkers for the diagnosis of Graves' disease with atrial fibrillation. METHODS: The expression profiles of eight serum microRNAs, which are found to be critical in the pathogenesis of atrial fibrillation, were determined in patients with Graves' disease with or without atrial fibrillation...

BACKGROUND: Synovitis-acne-pustulosis-hyperostosis-osteitis (SAPHO) syndrome is a rare disease and there is no related literature concerning psychiatric symptoms in SAPHO patients. Thus, we believe that this will be the first paper to explore the episode and the neurobiological basis of depression symptoms in SAPHO patients using resting state functional magnetic resonance imaging (rs-fMRI). Twenty-eight SAPHO patients and fifteen age- and gender- matched normal controls (NC) were consecutively submitted to psychiatric evaluation and rs-fMRI scanning...

The pathophysiology of erectile dysfunction post radical prostatectomy is not clearly clarified, and the low efficacy of traditional PDE5i treatment remains a major complaint in contemporary practice. This study aimed to demonstrate phenotypic modulation in bilateral cavernous nerve injury (BCNI) rats within 7 days, and subsequently validate gene therapy with Myocardin (Mycod) by maintaining a contractile phenotype in corpus cavernosum smooth muscle cells. Initially, 36 male rats were randomly divided into BCNI and negative control (NC) groups for histological and phenotypic molecular measurements at 3, 5, and 7 days...

NUT carcinomas (NC) are rare and aggressive tumours characterized by chromosomal rearrangements of the gene encoding for nuclear protein of the testis (NUT) located on chromosome 15q14. This article presents a case of a 60-year-old woman diagnosed with NC presenting as a fast growing primary tumour in the right palate. Further evaluation revealed a tumour mass in the lungs and widespread metastases. A review of the literature did not reveal earlier cases presenting in the palate. In order to improve early diagnosis it is suggested to perform immunohistochemical testing for NUT in all poorly differentiated carcinomas without glandular differentiation arising in the chest, and head and neck (Clin Cancer Res, 18, 2012, 5773)...

Stra8 (stimulated by retinoic acid gene 8) is a specific gene that is expressed in mammalian germ cells during transition from mitosis to meiosis and plays a key role in the initiation of meiosis in mammals and birds. So, the evaluation of the Stra8 pathway in cSSCs may provide a deeper insight into mammalian spermatogenesis. miRNA was also an important regulating factor for meiosis of SSCs. However, there is currently no data indicating that miRNA regulate the meiosis of SSCs via Stra8. Here, we predicted the prospective miRNA targeting to Stra8 using the online Bioinformatics database-Targetscan, and performed an analysis of the dual-luciferase recombinant vector, pGL3-CMV-LUC-MCS-Stra8-3'UTR...

BACKGROUND: Lack of accessible laboratory infrastructure limits HIV antiretroviral (ART) treatment initiation, monitoring and retention in many resource-limited settings. Point-of-care testing (POCT) is advocated as a mechanism to overcome these limitations. We executed a pragmatic, prospective, randomized, controlled trial comparing the impact of POCT versus standard-of-care (SOC) on treatment initiation and retention in care. METHOD: Selected POC technologies were embedded at 3 primary health clinics in South Africa...

The US Food and Drug Administration (FDA) issued a guidance document in 2010 on pharmacokinetic (PK) studies in renal impairment (RI) on the basis of observations that substances such as uremic toxins might result in altered drug metabolism and excretion. No specific recommendations for oncology drugs were included. We surveyed the publicly available FDA review documents of 29 small molecule oncology drugs approved between 2010 and the first quarter of 2015. The objectives were as follows: (i) summarize the impact of RI on PK at the time of the initial new drug application; (ii) identify limitations of the guidance; and (iii) outline an integrated approach to study the impact of RI on these drugs...

Objectives.: Persistent growth of Mycobacterium avium complex (MAC) in the lungs indicates continuous infection in MAC lung disease (MAC-LD), but its clinical significance has not been investigated. We aimed to evaluate the predictors of persistent culture-positivity and its impact on radiographic deterioration in MAC-LD. Methods.: MAC-LD patients at multiple medical centers from 2011 to 2016 were enrolled retrospectively. Microbiological persistence of MAC-LD was defined as persistent culture-positivity for MAC (MAC-PP) exceeding one year, in contrast with the negative conversion group (MAC-NC)...

STUDY QUESTION: How does the cognitive development of children conceived after ART (IVF and ICSI) - measured as cognitive skills at age 3, 5, 7 and 11 years - differ over time from those born after natural conception (NC)? SUMMARY ANSWER: Improved measures of cognitive development up to age 5 years were recorded in children conceived with ART compared to NC, which attenuates by 11 years, with ART children still scoring slightly better than NC children. WHAT IS KNOWN ALREADY: Results on the cognitive outcomes of children conceived after ART have been highly contradictory...

OBJECTIVES: The Luminex technology is the most sensitive diagnostic method for HLA antibody detection and identification. However, the interpretation of immunoassays is commonly affected by the artifact, and non-specific background. Sera from some patients show high negative control bead (NC) value, which makes assessing and interpretation of HLA antibodies difficult. In this study, we evaluated the effect of Adsorb Out reagent, dithiothreitol (DTT), and Ethylenediaminetetraacetic acid (EDTA) on the NC median fluorescence intensity value by comparing treated versus untreated patient sera...

Core-shell nanocarriers are increasingly being adapted in cosmetic and dermatological fields, aiming to provide an increased penetration of the active pharmaceutical or cosmetic ingredients (API and ACI) through the skin. In the final form, the nanocarriers (NC) are usually prepared in hydrogels, conferring desired viscous properties for topical application. Combined with the high chemical complexity of the encapsulating system itself, involving numerous ingredients to form a stable core and quantifying the NC and/or the encapsulated active without labor-intensive and destructive methods remains challenging...

CONTEXT: Heart, kidneys, and liver are the vital organs present in vertebrates and some other animals. They have a wide range of functions, such as maintaining homeostasis, detoxification, protein synthesis, and production of biochemical, that are necessary for digestion and maintaining circulation. These organs are necessary for the survival, and currently, there are no means to compensate for the absence of their functionalities in a long term. The damage of liver can affect other vital organs, including kidneys and heart...

Cytochrome P450 (P450, CYP) 21A2 is the major steroid 21-hydroxylase, converting progesterone to 11-deoxycorticosterone and 17α-hydroxy(OH)progesterone to 11-deoxycortisol. More than 100 CYP21A2 variants give rise to congenital adrenal hyperplasia (CAH). We previously reported a structure of wild-type (WT) human P450 21A2 with bound progesterone and now present a structure bound to the other substrate (17α-OH progesterone). We found that the 17α-OH progesterone- and progesterone-bound complex structures are highly similar, with only some minor differences in surface loop regions...
