BACKGROUND: The Breast Lesion Excision System(®) (BLES(®)) is a stereotactic vacuum-assisted breast biopsy device that utilizes radiofrequency in order to excise non-palpable mammographic lesions for pathologic diagnosis. The purpose of this study was to evaluate the efficacy of BLES(®) in performing complete, margin-free excisions of small solid carcinomas. METHODS: Our retrospective study of prospectively enrolled patients included 50 cases of non-palpable, BIRADS ≥ 4, solid by means of mammography and sonography, lesions...

In this paper, we used a classic basal ganglia-corticothalamic model(BGCT) to study the onset and control mechanism of absence epilepsy in specific relay nuclei (SRN) of thalamus. It was found that the seizure state may appear in SRN by turning the coupling strength -vsr and signal transmission delay τ on the route "Thalamic reticular nuclei (TRN) of thalamus ⟶ SRN ". With increasing of -vsr, the seizure state appeared two times, and its onset mechanism has not been discussed in previous studies. The seizure activity can be well controlled by adjusting the activation level of the substantia nigra pars reticulata (SNr) in basal ganglia, which is a main output tissue to the corticothalamic system through two direct inhibitory pathways "SNr ⟶ SRN" and "SNr ⟶ TRN " in our model...

Pressure controlled ventilation is a common mode of ventilation used to manage both adult and pediatric populations. However, there is very little evidence that distinguishes the efficacy of pressure controlled ventilation over that of volume controlled ventilation in the adult population. This gap in the literature may be due to the absence of a consistent and systematic algorithm for managing pressure controlled ventilation. This article provides a brief overview of the applications of both pressure controlled ventilation and volume controlled ventilation and proposes an algorithmic approach to the management of patients receiving pressure controlled ventilation...

We investigated the anticancer chemotoxicity of previously reported iodinated chlorin p6 copper complex (ICp6-Cu), a novel chlorophyll derivative in which copper is attached to the side chain carboxylate groups via coordination. Human oral carcinoma cells NT8e, 4451 and the non-cancerous keratinocyte HaCaT cells were treated with ICp6-Cu for 48 h in dark and cell viability, proliferation and morphological alterations were examined. ICp6-Cu showed pronounced cytotoxicity in cancer cells with IC50 ∼40 μM, whereas, the viability of HaCaT cells was not affected...

Yeast frataxin homolog (Yfh1) is the orthologue of human frataxin, a mitochondrial protein whose deficiency causes Friedreich Ataxia. Yfh1 deficiency activates Aft1, a transcription factor governing iron homeostasis in yeast cells. Although the mechanisms causing this activation are not completely understood, it is assumed that it may be caused by iron-sulfur deficiency. However, several evidences indicate that activation of Aft1 occurs in the absence of iron-sulfur deficiency. Besides, Yfh1 deficiency also leads to metabolic remodeling (mainly consisting in a shift from respiratory to fermentative metabolism) and to induction of Yhb1, a nitric oxide (NO) detoxifying enzyme...

OBJECTIVE: To compare BASDAI 50 response rate to TNFi in axial spondyloarthritis (axSpA) depending on the presence or not of objective signs of axSpA and to look for predictive factors of TNFi efficacy. METHODS: Patients diagnosed with axSpA according to ASAS criteria "clinical arm" and treated between January 2001 and September 2015 with TNFi were included. First group included patients with at least one objective sign such as arthritis, dactylitis, enthesitis, uveitis, inflammatory bowel disease, elevated C-reactive protein or radiological sacroiliitis, and second group included non-radiographic axSpA (nr-axSpA) patients without any objective sign corresponding to patients with inflammatory back pain and either a good response to NSAID or a SpA family history...

Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS) and Alzheimer's disease (AD) are neurodegenerative diseases that may share genetic risk factors. The exon variant Aal58Val (rs17571) in CTSD was recently associated with AD, leading us to examine whether it also affects risk of ALS and PD. The rs17571 variant was genotyped using the ligase detection reaction in 569 Han Chinese patients with PD, 301 patients with ALS, and healthy controls age- and gender-matched to each patient group. The frequencies of genotypes and alleles were similar between each disease group and its respective control group...

The aim of our paper was to provide comprehensive data on the prevalence of absence of palmaris longus muscle (PLM) and its anatomical characteristics and conduct two separate meta-analyses comparing cadaveric and functional studies while identifying variation among different ethnic groups. An extensive search was conducted through the major electronic databases to identify eligible articles. Data extracted included prevalence of absence of PLM among subjects, ethnicity, laterality, side, and gender. Our main findings revealed that the absence of PLM is more frequently reported in functional studies...

Circulating blood cells, and cell-derived microvesicles, are emerging as pragmatic delivery systems that can smartly complement the already existing nanotherapeutic platforms evaluated to treat or diagnose diseases. The valuable distinctive features of circulatory cells over synthetic nanocarriers encompass their biological origin which confers immune transparence, known biodegradability, high drug loading, relatively long half-life and a targeting capacity associated with their physiological surface functionality...

OBJECTIVES: This study sought to investigate the incidence, associated findings, and natural history of effusive-constrictive pericarditis (ECP) after pericardiocentesis. BACKGROUND: ECP is characterized by the coexistence of tense pericardial effusion and constriction of the heart by the visceral pericardium. Echocardiography is currently the main diagnostic tool in the assessment of pericardial disease, but limited data have been published on the incidence and prognosis of ECP diagnosed by echo-Doppler...

BACKGROUND: The human frequency-following response (FFR) is a neurophonic potential used to examine the brain's encoding of complex sounds (e.g., speech) and monitor neuroplastic changes in auditory processing. Given the FFR's low amplitude (order of nanovolts), current conventions in literature recommend collecting several thousand trials to obtain a robust evoked response with adequate signal-to-noise ratio. NEW METHOD: By exploiting the spectrotemporal fidelity of the response, we examined whether auditory playbacks (i...

BACKGROUND: Primary immune thrombocytopenia is a severe bleeding disorder. About 50-85% of patients achieve initial remission from first-line therapies, but optimal second-line treatment remains a challenge. All-trans retinoic acid (ATRA) has an immunomodulatory effect on haemopoiesis, making it a possible treatment option. We aimed to evaluate the efficacy and safety of ATRA plus danazol versus danazol in non-splenectomised patients with corticosteroid-resistant or relapsed primary immune thrombocytopenia...

Bovine satellite cell (bSC) myogenesis and skeletal muscle hypertrophy occur through the orchestrated actions of multiple autocrine and paracrine growth factors. Intimate to the bSC niche is IL6, a dual-purpose cytokine with proinflammatory and mitogenic properties. The objective of the experiment was to examine the effects of IL6 on proliferation and differentiation of bSC in vitro. Treatment of primary bSC cultures with recombinant bovine IL6 (bIL6) failed to alter myogenesis owing to the absence of intracellular signal transduction...

OBJECTIVE: To identify the critical factors that determine recommendations and other decisions about health care related tests and diagnostic strategies (HCTDS). METHODS: We used a qualitative descriptive approach and conducted semi-structured in-depth interviews with 24 international experts (informants) in evidence and decisions about HCTDS. RESULTS: Although test accuracy (TA) was the factor most commonly considered by organizations when developing recommendations about HCTDS, informants agreed that TA is necessary but rarely, if ever, sufficient and may be misleading when solely considered...

The effects of early environmental enrichment (EE) when solving a simple spatial task in adult male rats were assessed. After weaning, rats were housed in pairs in enriched or standard cages (EE and control groups) for two and a half months. Then the rats were trained in a triangular-shaped pool to find a hidden platform whose location was defined in terms of two sources of information, a landmark outside the pool and a particular corner of the pool. As expected, enriched rats reached the platform faster than control animals...

BACKGROUND: The incidence of cancer is increased in patients with systemic sclerosis (SSc). Further, recent studies have also shown that the presence of anti-RNA polymerase III antibodies is associated with a higher incidence of cancer in this population. PATIENTS AND METHODS: Herein we present the cases of two men aged 56 and 23 years presenting SSc without anti-Scl70 or anti-centromere antibodies but with anti-RNA polymerase III antibodies. Clinical symptoms led us to prescribe more laboratory exams and both patients were diagnosed with cancer of the nasopharyngeal area...

BACKGROUND: Current phase mapping systems for atrial fibrillation(AF) create two-dimensional(2D) maps. This process may affect the accurate detection of rotors. We developed a three-dimensional(3D) phase mapping technique that utilizes the 3D locations of basket electrodes to project phase onto patient-specific left atrial(LA) 3D surface anatomy. OBJECTIVES: We sought to determine whether rotors detected in 2D phase maps were present at corresponding time segments and anatomical locations on 3D phase maps...

Antagonistic interactions between hosts and parasites are key structuring forces in natural populations. Demographic factors like extinction, migration and the effective population size shape host-parasite metapopulational dynamics. Therefore, to understand the evolution of host-parasite systems it is necessary to study the distribution of the genetic variation of both entities simultaneously. In this paper, we investigate the population genetics co-structure of parasites and hosts within a metapopulation of the liver fluke, Fasciola hepatica, and two of its intermediate hosts, the main intermediate host in Europe, Galba truncatula, and a new intermediate host, Omphiscola glabra, in Central France...
