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...

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...

The ideal implant for the treatment of an unstable intertrochanteric femoral fracture is still a matter of discussion. The aim of this systematic review is to conduct a network meta-analysis of randomized controlled trials (RCTs) comparing clinical outcomes between dynamic hip screws (DHS), Medoff sliding plating, percutaneous compression plating (PCCP), proximal femoral nails (PFN), Gamma nails and less invasive stabilization system fixation in femoral trochanteric fractures in the elderly. These clinical outcomes consist of total intra-operative time, intra-operative fluoroscopy time, intra-operative blood loss, blood component transfusion, length of hospital stay, postoperative general complications, wound complications, late complications and reoperation rates...

Wu-tou Decoction (WTD) is a famous traditional Chinese medicine (TCM) formula which is applied to treat arthritis and pain of joints. In this study, a sensitive and rapid method was developed for the separation and identification of the absorbed constituents and metabolites of WTD in the rats plasma by ultra high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UHPLC-Q-TOF-MS). A total of 22 absorbed prototype constituents and 49 metabolites were identified or tentatively characterized in dosed plasma...

OBJECTIVE: To investigate the diagnostic accuracy of various evoked potential monitoring techniques in predicting postoperative neurological deficit in intracranial aneurysm surgery. METHODS: A literature search of the MEDLINE, Embase and Cochrane databases was conducted for English language papers published between 31 March 1983 and 31 March 2016. Original studies that reported the use of evoked potential monitoring during intracranial aneurysm surgery in predicting postoperative neurological damage were selected, and their relevant reference lists were hand searched...

Mono-ethylene glycol (MEG) is an important petrochemical with widespread use in numerous consumer products. The current industrial MEG-production process relies on non-renewable fossil fuel-based feedstocks, such as petroleum, natural gas, and naphtha; hence, it is useful to explore alternative routes of MEG-synthesis from gases as they might provide a greener and more sustainable alternative to the current production methods. Technologies of synthetic biology and metabolic engineering of microorganisms can be deployed for the expression of new biochemical pathways for MEG-synthesis from gases, provided that such promising alternative routes are first identified...

BACKGROUND: The prior literature has suggested a potential increase in colorectal cancer (CRC) among patients with breast cancer. METHODS: We performed a systematic review of the literature and included 37 retrospective cohort studies and 8 case-control studies. The primary aim was to determine the prevalence of CRC. Secondary aims included analysis of adenomatous polyps and analysis of CRC prevalence by age. We calculated pooled prevalence rates and odds ratios using random effects models with 95% confidence intervals (CI)...

INTRODUCTION: Cytotoxic chemotherapy is the mainstay treatment for metastatic colorectal cancer (mCRC). Fluoropyrimidines, oxaliplatin, and irinotecan are the most active drugs; however, their optimal sequencing has not yet been established. Some evidence has shown that upfront treatment with 5-fluorouracil, oxaliplatin, and irinotecan (FOLFOXIRI regimen) can improve outcomes for patients with mCRC. MATERIALS AND METHODS: We performed a systematic search in electronic databases...

Amanita subpallidorosea is a recently discovered lethal Amanita sect. Phalloideae species found in China that is clustered with A. virosa in the same clade based on molecular phylogenetic analysis. However, the cyclopeptide toxin contents of these lethal mushrooms remain poorly studied. In this study, the cyclopeptide toxins in A. subpallidorosea were reported for the first time and the cyclopeptide compositions of A. subpallidorosea and A. virosa species were systematically analyzed. Thirteen cyclopeptides and two unknown compounds were identified or observed from these two lethal mushrooms by high-performance liquid chromatography coupled with high-resolution mass spectrometry...

INTRODUCTION: Asymptomatic Toxoplasma gondii transmitted from blood donors to receiving patients has become a concern. Numerous articles have been published on the epidemiology of T. gondii in blood donors in Iran and a systematic review of the results shows quite different findings, hence this study was conducted to determine the seroprevalence of T. gondii in Iranian blood donors using meta-analysis. METHODS: We searched for epidemiological studies that were published until July 2016 in eight English databases including: Scopus, PubMed, Ovid, Science Direct, Cochrane, Web of Science, Springer, Wiley Online Library, and four Iranian databases: Magiran, Iranmedex, SID and Medlib as well as Google Scholar...

Within the Poisson-Boltzmann approach, electrolytes in contact with planar, spherical, and cylindrical electrodes are analyzed systematically. The dependences of their capacitance C on the surface charge density σ and the ionic strength I are examined as a function of the wall curvature. The surface charge density has a strong effect on the capacitance for small curvatures, whereas for large curvatures the behavior becomes independent of σ. An expansion for small curvatures gives rise to capacitance coefficients which depend only on a single parameter, allowing for a convenient analysis...

Here, a facile self-templating approach has been presented for synthesis of hollow and yolk-shell mesoporous silica nanoparticles (HMSNs and YMSNs) through a selective etching of hybrid silica nanoparticles. The hybrid silica nanoparticles are from the co-condensation of tetraethylorthosilicate (TEOS) and N-[3-(trimethoxysilyl)propyl]ethylenediamine (TSD) by a simple one-step process. Two kinds of products including HMSNs and YMSNs can be easily prepared only by tuning the TSD amounts in the precursor. Significantly, the transformation of hollow structure does not use any sacrificial template and surface protective agent...

Eczema is a common, long-term condition but inadequate support and information can lead to poor adherence and treatment failure. We have reviewed the international literature of interventions designed to promote self-management in adults and children with eczema. MEDLINE, MEDLINE in process, EMBASE, CINAHL and GREAT were searched from their inception to August 2016 for randomised controlled trials. Two authors independently applied eligibility criteria, assessed risk of bias for all included studies and extracted data...
