BACKGROUND: Buruli ulcer (BU) is a subcutaneous skin disease listed among the neglected tropical diseases by the World Health Organization (WHO). Early case detection and management is very important to reduce morbidity and the accompanied characteristic disfiguring nature of BU. Since diagnosis based on clinical evidence can lead to misdiagnosis, microbiological confirmation is essential to reduce abuse of drugs; since the anti-mycobacterial drugs are also used for TB treatment. The current WHO gold standard PCR method is expensive, requires infrastructure and expertise are usually not available at the peripheral centers where BU cases are managed...

Mafenide acetate is used in some burn wounds for its ability to penetrate eschar but requires frequent uncomfortable dressing changes for its application. The authors hypothesize that hydrofiber dressings will hold mafenide acetate solution for an extended period of time and maintain antimicrobial activity longer than traditional gauze, thus possibly obviating the need for frequent dressing changes. Four experimental arms included: 1) hydrofiber, stored on a dry well plate as control, 2) gauze saturated with 2...

OBJECTIVE: Coronary heart disease (CHD) is a frequent medical condition in developed countries and is one of the most serious diseases threatening patients' lives. Perioperative myocardial infarction is the major cause of perioperative cardiac death and cardiac arrest, but is difficult to be precisely identified by observing clinical symptoms or assessing cardiac enzyme levels or by ECG examination. Therefore, assessment of patient prognosis requires reliable predictors. In this regard, we tested the prognostic value of serum troponin I (TnI) concentrations...

OBJECTIVE: Transcatheter aortic valve replacement (TAVR) has been accepted as an alternative to surgery in high risk or inoperable patients with severe aortic stenosis (AS). Although transfemoral approach is the most often preferred means of access, in patients with severe ilio-femoral arteriopathy, other vascular access sites may be required. The aim of the present study was to report our experience with trans-subclavian approach for TAVR using different valve systems. METHODS: Among 273 patients undergoing TAVR between June 2011 and May 2016, 10 patients (mean age: 68...

Objective To prepare Rev-erbβ knockout HEK293 cells using clustered regularly interspaced short palindromic repeats/Cas 9 nuclease (CRISPR/Cas9) gene editing technology. Methods The knock-in or knockout of Rev-erbβ gene could be realized by single-guide RNA (sgRNA)-mediated Cas9 cutting of target DNA, and followed by DNA homologous recombination or non-homologous end joining-mediated DNA repair. Firstly, four sgRNAs were designed for Rev-erbβ gene. The sgRNA1 and sgRNA2 with the higher activity were respectively used to construct pCMV-hCas9-U6-Rev-erbβ sgRNA1 and pCMV-hCas9-U6-Rev-erbβ sgRNA2...

BACKGROUND: Estrogens and their synthetic analogues are widely used as pharmaceuticals. Upon oral administration these drugs are eventually excreted via urine. The persistence of these pharmaceuticals and inefficient removal by water treatment lead to accumulation in surface water and effluents with negative effects for aquatic life and human health. METHODS: In this study, the uptake of estradiol by a combined magnetic ion exchange resin - ultrafiltration process (MIEX-UF) was investigated...

Identifying genetic alterations in tumors is critical for molecular targeting of therapy. In the clinical setting, formalin-fixed paraffin-embedded (FFPE) tissue is usually employed for genetic analysis. However, DNA extracted from FFPE tissue is often not suitable for analysis because of its low levels and poor quality. Additionally, FFPE sample preparation is time-consuming. To provide early treatment for cancer patients, a more rapid and robust method is required for precision medicine. We present a simple method for genetic analysis, called touch imprint cytology combined with massively paralleled sequencing (touch imprint cytology [TIC]-seq), to detect somatic mutations in tumors...

During a fiber post cementation, bonding failure often occurs at the junction between the fiber-post and resin-cement. Because this failure requires better characterization, we evaluated if different post surface treatment can affect the bond strength of urethane dimethacrylate (UDMA) fiber-posts with resin-cements. Three groups were created: G1: no treatment/silane; G2: ethyl alcohol (96° GL)/silane; G3: 24% H2O2/silane and further divided into four subgroups: I-Unicem/3MESPE; II-BisCem/Bisco; III-Panavia SA/Kuraray and IV-DuoLink/Bisco...

AIM: Increased afferent fibre activity contributes to pathological conditions such as the overactive bladder syndrome. Nerve fibres running near the urothelium are considered to be afferent as no efferent system has yet been described. The aim of this study was to identify sub-types of afferent nerve fibres in the mouse bladder wall based on morphological criteria and analyse regional differences. MATERIALS AND METHODS: 27 bladders of six month old C57BL/6 mice were removed and tissues were processed for immunohistochemistry...

Sudden unexpected death in epilepsy (SUDEP) is the leading cause of mortality in patients with refractory epilepsy, and as such has been a major research focus over the last 25 years. The earliest SUDEP research papers were published in Seizure, as have scores of SUDEP papers since. In this review we discuss the efforts to try and describe the pathophysiological basis of SUDEP, the drive to discover the clinical risk factors that increase the likelihood of SUDEP, and the motivation to increase awareness of SUDEP...
