#1
S Wei, Y Yu, Q Qin
A new cell line derived from the caudal fin of golden pompano Trachinotus ovatus (TOCF) was successfully established and characterized. TOCF cells grew well at 28° C in L-15 medium supplemented with 10% foetal bovine serum (FBS). The cell line has been subcultured in more than 100 passages. Molecular characterization of 18S ribosomal (r)RNA and cytochrome oxidase subunit 1 (COI) confirmed that the TOCF cells were derived indeed from T. ovatus. TOCF cells have a modal chromosome number of 54. It was further showed that TOCF cells were transfected successfully with pEGFP-N3 and pDsRED-N1 plasmid, suggesting that TOCF cells could be used to research gene functions in vitro...

Cheng Guo, Cheng Shen, Qiang Li, Jiubin Tan, Shutian Liu, Xinchi Kan, Zhengjun Liu
Multiple distance phase retrieval methods hold great promise for imaging and measurement due to their less expensive and compact setup. As one of their implementations, the amplitude-phase retrieval algorithm (APR) can achieve stable and high-accuracy reconstruction. However, it suffers from the slow convergence and the stagnant issue. Here we propose an iterative modality named as weighted feedback to solve this problem. With the plug-ins of single and double feedback, two augmented approaches, i.e. the APRSF and APRDF algorithms, are demonstrated to increase the convergence speed with a factor of two and three in experiments...

Teresa G Odle
Screening mammography introduces low doses of radiation per examination and in regular intervals over decades for women who have annual screening. Further, advanced breast imaging modalities and follow-up imaging methods contribute to additional radiation exposure in radiosensitive breast tissue. This article reviews the effects of radiation on the breasts, summarizes dose measurements and estimates for breast imaging modalities, and discusses efforts to optimize dose in breast imaging.

Kevin R Clark
Earthquakes are a devastating phenomena of nature, causing significant destruction and extensive damage. Most earthquake-related injuries result from collapsing buildings, flying debris, and falling objects. Medical imaging modalities, in particular digital radiography, computed tomography, and sonography, are used to help manage and treat patients injured during an earthquake. Therefore, health care providers, including radiologic technologists, must be aware of the imaging considerations associated with earthquake-related injuries...

Interferon alpha/beta (IFN-α/β) is a critical mediator of protection against most viruses, with host survival frequently impossible in its absence. Many studies have investigated the pathways involved in the induction of IFN-α/β after virus infection and the resultant upregulation of antiviral IFN-stimulated genes (ISGs) through IFN-α/β receptor complex signaling. However, other than examining the effects of genetic deletion of induction or effector pathway components, little is known regarding the functionality of these responses in intact hosts and whether host genetic or environmental factors might influence their potency...

The use of sensory information to control behavior usually involves the integration of sensory input from different modalities. This integration is affected by behavioral states and experience, and it is also sensitive to the spatiotemporal patterns of stimulation and other general contextual cues. Following the finding that hawkmoths can use relative humidity (RH) as a proxy for nectar content during close-range foraging, we evaluate here whether RH could be used during locomotive flight under two simulated contexts in a wind tunnel: 1) dispersion, and 2) search phase of the foraging behavior...

Heart failure (HF) is a threat to public health. Heterogeneities in etiology and phenotype complicate the diagnosis and management of HF. This is especially true when considering HF with preserved ejection fraction (HFpEF) which make up 50% of HF cases. Natriuretic peptides may aid in establishing a working diagnosis in patients suspected of HF, but echocardiography remains the optimal choice for diagnosing HF. Echocardiography provides important prognostic information in both HF with reduced ejection fraction (HFrEF) and HFpEF...

BACKGROUND: Debridement, antibiotics, and implant retention (DAIR) is a widely used treatment modality for early acute prosthetic joint infection (PJI). A preoperative risk score was previously designed for predicting DAIR failure, consisting of chronic renal failure (K), liver cirrhosis (L), index surgery (I), cemented prosthesis (C), and C-reactive protein >115 mg/L (KLIC). The aim of this study was to validate the KLIC score in an external cohort. METHODS: We retrospectively evaluated patients with early acute PJI treated with DAIR between 2006 and 2016 in 3 Dutch hospitals...

This study presents a novel method for the detection and classification of a wide range of physical activities, including standing, sitting, lying, level walking, and walking upstairs and downstairs using a single chest-mounted accelerometer. The trunk inclination angle and variation of the gravitational component of the accelerometer recording were used for detection and classification of postural transitions and walking modalities. In addition, biomechanical features of each transition were used to reject false detections...

Temporary transcutaneous pacing devices are used to treat symptomatic bradyarrhythmias that are unresponsive to medical therapy until it resolves or a more stable pacing device is established. Pain is the most common complication. Skin burns as a complication are uncommon. A female patient presented with a complete atrioventricular block that caused altered mental status and required orotracheal intubation. A temporary transcutaneous pacing device was used to treat the bradyarrhythmia and maintained for 12 h until a temporary transvenous pacemaker was placed...

BACKGROUND: Renal colic is a frequently encountered diagnosis among emergency department patients. Point-of-care (POC) ultrasound has taken on an increasingly important role in the diagnostic strategy of this disease, as it has been shown to be an effective modality for diagnosis and for guiding management. The primary pathology that the emergency physician will evaluate for in cases of suspected renal colic is hydronephrosis, which is a dilatation of the renal pelvis and calyces resulting from a distal obstruction such as a ureteral stone...

Imaging of the spine is extensively applied in the assessment of patients with low back pain, who often expect imaging procedures to be undertaken. However, the majority of conventional imaging techniques have questionable precision in identifying the primary structural source of pain. This has led to increasing scientific interest in emerging new medical imaging modalities, since adequate correlation between imaging findings and symptoms is crucial for referring clinicians to optimize patient treatment plans...

BACKGROUND: Although transthoracic echocardiography is the dominant imaging modality in CHD, optimal utilisation is unclear. We assessed whether adherence to the paediatric Appropriate Use Criteria for outpatient transthoracic echocardiography could reduce inappropriate use without missing significant cardiac disease. METHODS: Using the Appropriate Use Criteria, we determined the indication and appropriateness rating for each initial echocardiogram performed at our institution during calendar year 2014 (N=1383)...

Objective Autologous articular cartilage (AC) harvested for repair procedures of high weight bearing (HWB) regions of the femoral condyles is typically obtained from low weight bearing (LWB) regions, in part due to the lack of non-destructive techniques for cartilage composition assessment. Here, we demonstrate that infrared fiber optic spectroscopy can be used to non-destructively evaluate variations in compositional and mechanical properties of AC across LWB and HWB regions. Design AC plugs ( N = 72) were harvested from the patellofemoral groove of juvenile bovine stifle joints, a LWB region, and femoral condyles, a HWB region...

The paper will draw on materials from arts therapies literature and comments from experts’ panels to discuss some specific characteristics of the arts therapies and to investigate the role of aesthetic engagement for resilience and mental well-being. The arts increasingly find their way as interventions in mental health domains. However, explorations into the specific mechanisms that underpin the therapeutic effect of arts-based activities are still scarce. Qualitative data were collected from a thematic literature review and expert comments on meaningful working procedures in arts therapies...

Polymyalgia rheumatica (PMR) and large-vessel vasculitis (LVV) are related rheumatic diseases which are occasionally present concomitantly. PMR is characterized by synovitis and bursitis. In LVV, inflammation of the blood vessel wall is seen. Both disorders can be difficult to diagnose since patients often present non-specific symptoms and results of blood tests. The non-specific symptoms cannot always be distinguished from symptoms indicating an occult malignancy. We present a case of PMR and LVV in a Scandinavian man visualized on [18 F]-2-deoxy-D-glucose positron emission tomography/computed tomography (18 F-FDG PET/CT) with the presentation of typically affected sites of joints and arteries and with the same imaging modality ruling out occult malignancy...

Colovaginal and/or rectovaginal fistulas cause significant and distressing symptoms, including vaginitis, passage of flatus/feces through the vagina, and painful skin excoriation. These fistulas can be a challenging condition to treat. Although most fistulas can be treated with surgical repair, for those patients who are not operative candidates, limited options remain. As minimally-invasive interventional techniques have evolved, the possibility of fistula occlusion has enriched the therapeutic armamentarium for the treatment of these complex patients...

The genus Rhinogobius Gill 1859 is widely distributed in fresh waters along the Western Pacific coast of tropical and temperate Asia. A new species, Rhinogobius maxillivirgatus, is described from Anhui Province in Eastern China. This species can be differentiated from all congeners by a combination of the following characters: up to 6 longitudinal brown to black stripes along the side of the body; pectoral-fin rays modally 14; predorsal scale series 5-9; lateral scale series 28-30; transverse scale series 6-7; branchiostegal membrane with about 20 red round spots in males; and 2 black oblique stripes parallel along the upper jaw on the anterior portion of the cheek...

It is known that the symptoms of Parkinson's disease (PD) progress successively, early and accurate diagnosis of the disease is of great importance, which slows the disease deterioration further and alleviates mental and physical suffering. In this paper, we propose a joint regression and classification scheme for PD diagnosis using baseline multi-modal neuroimaging data. Specifically, we devise a new feature selection method via relational learning in a unified multi-task feature selection model. Three kinds of relationships (e...

INTRODUCTION: The incidence of acute appendicitis is approximately 250,000 cases per year in the United States with a lifetime risk of 7% (Gupta & Dupuy, 1997). However, despite strongly associated clinical signs, diagnostic accuracy based on history and physical exam alone is only 70% (Jess et al., 1981). This is in large part due to the multitude of mimics found in the differential diagnosis of appendicitis. As a result highly sensitive imaging such as computed tomography scan has become standard of care...
