The genus Laminaria has a wide distribution range compared with other kelp genera because it is found in both the North and the South Atlantic, on both sides of the North Pacific, as well as in the Mediterranean. Hypotheses behind this biogeographical pattern have been discussed by several authors but have not yet been fully evaluated with time-calibrated phylogenies. Based on the analysis of four molecular markers (ITS2, rbcL, atp8 and trnWI), our goal was to reassess the Laminaria species diversity in South Africa, assess its relationship to the other species distributed in the South Atlantic and reconstruct the historical biogeography of the genus...

Previous publications list ten species in the Laurencia complex from South Africa with all ascribed to the genus Laurencia sensu stricto. However, the diversity of the complex in South Africa has not yet been reassessed following the numerous recent taxonomic changes. The present study investigated the phylogenetic relationships and taxonomy of this group in South Africa using recent collections. Methods included a molecular phylogenetic analysis of plastid rbcL gene sequences (a total of 146; including eleven outgroup taxa) using Bayesian Inference, and the examination of morphological and anatomical characters, including the number of corps en cerise when present...

BACKGROUND: Topiramate is a newer broad-spectrum antiepileptic drug (AED). Some studies have shown the benefits of topiramate monotherapy in the treatment of juvenile myoclonic epilepsy (JME). However, there are no current systematic reviews to determine the efficacy and tolerability of topiramate monotherapy in people with JME. This is an updated version of the original Cochrane Review published in Issue 12, 2015. OBJECTIVES: To evaluate the efficacy and tolerability of topiramate monotherapy in the treatment of JME...

We published a phylogenetic comparative analysis that found geckos had gained and lost adhesive toepads multiple times over their long evolutionary history (Gamble et al. 2012). This was consistent with decades of morphological studies showing geckos had evolved adhesive toepads on multiple occasions and that the morphology of geckos with ancestrally padless digits can be distinguished from secondarily padless forms. Recently, Harrington and Reeder (2017) reanalyzed data from Gamble et al. (2012) and found little support for the multiple origins hypothesis...

Marine sediments contain eukaryotic DNA deposited from overlying water columns. However, a large proportion of deposited eukaryotic DNA is aerobically biodegraded in shallow marine sediments. Cold seep sediments are often anaerobic near the sediment-water interface, so eukaryotic DNA in such sediments is expected to be preserved. We investigated deeply buried marine sediments in the Japan Sea, where a methane hydrate deposit is associated with cold seeps. Quantitative PCR analysis revealed the reproducible recovery of eukaryotic DNA in marine sediments at depths up to 31...

Sexual traits (e.g., visual ornaments, acoustic signals, courtship behaviour) are often displayed together as multi-modal signals. Some hypotheses predict joint evolution of different sexual signals (e.g., to increase the efficiency of communication), or that different signals trade-off with each other (e.g., due to limited resources). Alternatively, multiple signals may evolve independently for different functions, or to communicate different information (multiple message hypothesis). We evaluated these hypotheses with a comparative study in the family Estrildidae, one of the largest songbird radiations, and one that includes many model species for research in sexual selection and communication...

A Gram-stain negative, rod-shaped, aerobic bacterial strain, designated TA-C7e(T), was isolated from an agricultural soil obtained from Taean region, Korea. Phylogenetically, the strain was grouped with the genus Massilia and shared 95.33-97.97% 16S rRNA sequence similarity with the type strains of other species of the genus Massilia. The DNA-DNA hybridisation between TA-C7e(T) and Massilia haematophila KACC 13771(T), Massilia suwonesis KACC 12635(T), and Massilia yuzhufengensis KACC 16569(T) revealed a low level of relatedness (<40%)...

Despite remarkable progress in imaging modalities and surgical management, persistence or recurrence of primary hyperparathyroidism (PHPT) still occurs in 2.5-5% of cases of PHPT. The aim of this review is to expose the management of persistent and recurrent hyperparathyroidism. A literature search was performed on MEDLINE using the search terms "recurrent" or "persistent" and "hyperparathyroidism" within the past 10 years. We also searched the reference lists of articles identified by this search strategy and selected those we judged relevant...

Large tumor suppressor (LATS) is an important member of the Hippo pathway which can regulate organ size and cell proliferation. However, very little is known about the expression and clinical significance of LATS in lung cancer especially from this part of the world. We elucidated the frequency of LATS1 &LATS2 promoter hypermethylation (by methylation-specific PCR) and expression (by real-time PCR) in sixty nine (n = 69) Non-Small Cell Lung Cancer (NSCLC) patients and their corresponding normal lung tissue samples...

The Pain Resilience Scale was recently developed to assess dimensions of resilience critical to pain-related adaptation and was found to predict experimental pain sensitivity in a pain-free population. Pain resilience has also been theoretically linked to behavioral persistence despite pain. To date, however, this hypothesis has not been experimentally tested. To address this gap in the literature, in the current study 105 healthy young adults underwent a baseline administration of the Paced Auditory Serial Addition Test (PASAT), a stressful mental arithmetic task, delivered with somatosensory distraction (i...

Many studies have shown that schizophrenia patients have aberrant functional network connectivity (FNC) among brain regions, suggesting schizophrenia manifests with significantly diminished (in majority of the cases) connectivity. Schizophrenia is also associated with a lack of hemispheric lateralization. Hoptman et al. (2012) reported lower inter-hemispheric connectivity in schizophrenia patients compared to controls using voxel-mirrored homotopic connectivity. In this study, we merge these two points of views together using a group independent component analysis (gICA)-based approach to generate hemisphere-specific timecourses and calculate intra-hemisphere and inter-hemisphere FNC on a resting state fMRI dataset consisting of age- and gender-balanced 151 schizophrenia patients and 163 healthy controls...

OBJECTIVE: Hypothyroidism is complicated by neuromuscular symptoms (myalgias, slowness of movements, and tiredness) and signs (easy fatigability and cramps), which may have a negative impact on general well-being and quality of life. In a pilot, prospective, controlled study, we investigated the features of muscle dysfunction in hypothyroidism by disease questionnaire, biochemical measures, and physical performance tests. MATERIALS AND METHODS: Fifty-seven consecutive patients with newly diagnosed hypothyroidism were enrolled, 27 subclinical (S-Hypo) and 30 overt (O-Hypo)...

Coordination of cell division and cell fate is crucial for the successful development of mammalian early embryos. Aurora kinases are evolutionarily conserved serine/threonine kinases and key regulators of mitosis. Aurora kinase B (AurkB) is ubiquitously expressed while Aurora kinase C (AurkC) is specifically expressed in gametes and preimplantation embryos. We found that increasing AurkC level in one blastomere of the 2-cell embryo accelerated cell division and decreasing AurkC level slowed down mitosis. Changing AurkB level had the opposite effect...

Various typical and atypical neurological manifestations can be seen as the initial symptoms of celiac disease (CD). We suggest that gluten toxicity is the most suspicious triggering risk factor for probable pathophysiological pathways of neurological involvement in atypical CD. The medical charts of 117 patients diagnosed with atypical CD were retrieved from a tertiary center in Ankara, Turkey. Eight patients reported as having neurologic manifestations as initiating symptoms were evaluated in detail. The initial neurological manifestations of CD in our study included atypical absence, which was reported first in this study, generalized tonic-clonic seizures, complex partial seizures, severe axial hypotonia and down phenotype, multifocal leukoencephalopathy, mild optic neuritis, attention deficit hyperactivity disorder, and short duration headaches...

INTRODUCTION: Lamotrigine is used in pregnancy to control epilepsy and mood disorders. The reproductive safety of this widely used drug remains undefined and may represent a significant public health concern. OBJECTIVE: We aimed to perform a systematic review and meta-analysis of existing knowledge related to malformation rates and maternal-neonatal outcomes after in utero exposure to monotherapy with lamotrigine. METHODS: Relevant studies were identified through systematic searches conducted in MEDLINE (Ovid), Embase (Ovid), CENTRAL (Ovid), and Web of Science (Thomson Reuters) from database inception to July 2016; no language or date restrictions were applied...

Transfer is a desired outcome of simulation-based training, yet evidence for how instructional design features promote transfer is lacking. In clinical reasoning, transfer is improved when trainees experience instruction integrating basic science explanations with clinical signs and symptoms. To test whether integrated instruction has similar effects in procedural skills (i.e., psychomotor skills) training, we studied the impact of instruction that integrates conceptual (why) and procedural (how) knowledge on the retention and transfer of simulation-based lumbar puncture (LP) skill...

A cold-adapted bacterium, Shewanella livingstonensis Ac10, which produces eicosapentaenoic acid (EPA) as a component of its membrane phospholipids, is useful as a model to study the function of EPA and as a host for heterologous production of thermolabile proteins at low temperatures. In this study, we characterized extracellular membrane vesicles (EMVs) of this bacterium to examine the involvement of EPA in the biogenesis of EMVs and for the future application of EMVs to extracellular protein production. We found that this strain produced EMVs from the cell surface...
