A dominant view of the role of the anterior temporal lobe (ATL) in semantic memory is that it serves as an integration hub, specialized in the processing of semantic relatedness by way of mechanisms that bind together information from different brain areas to form coherent amodal representations of concepts. Two recent experiments, using brain stimulation techniques along with the Deese-Roediger-McDermott (DRM) paradigm, have found a consistent false memory reduction effect following stimulation of the ATL, pointing to the importance of the ATL in semantic/conceptual processing...

Site-specific recombinases are potent tools to regulate gene expression. In particular, the Cre and FLP enzymes are widely used to either activate or inactivate genes in a precise spatiotemporal manner. Both recombinases work efficiently in the popular model organism Caenorhabditis elegans but their use in this nematode is still only sporadic. To increase the utility of the FLP system in C. elegans we have generated a series of single-copy transgenic strains that stably express an optimized version of FLP in specific tissues or by heat induction...

Mango (Mangiferaindica L.) fruits are generally classified based on peel color into green, yellow, and red types. Mango peel turns from green to yellow or red or retain green colors during ripening. The carotenoids and anthocyanins are the important pigments responsible for the colors of fruits. In the present study, peels of different colored cultivars at three ripening stages were characterized for pigments, colors, and gene expression analysis. The yellow colored cultivar "Arka Anmol" showed higher carotenoid content, wherein β-carotene followed by violaxanthin were the major carotenoid compounds that increased during ripening...

INTRODUCTION: While medications may prolong life and prevent morbidity in older people, adverse effects of polypharmacy are increasingly recognised. As patients age and become frail, prescribing may be expected to focus more on symptom control and minimise potentially harmful preventive medication use that confer little benefit within a short lifespan. Whether prescribing practice shifts to one of symptom control among the oldest old admitted to hospital remains unclear. METHODS: Retrospective analysis of all patients aged ≥85 years referred for comprehensive geriatric assessment at a tertiary care hospital between May 2006 and December 2014 for whom all prescribed medications were documented...

REVIEW
Livnat Goldenberg, Yossi Yaniv, Ron Porat, Nir Carmi
During the last decade, there has been a continuous rise in consumption and global marketing of fresh, easy-to-peel mandarins, with current annual production of nearly 29 million tons. Nevertheless, most of the existing knowledge on quality traits of citrus fruit comes from research conducted on oranges and grapefruit, which are the main products for the citrus juice manufacturing industry; relatively little is yet known regarding the unique fruit quality traits of mandarins, nor about the great diversity in these traits among the various natural sub-groups and varieties of mandarins...

BACKGROUND: Skin color is determined by melanin contents and its distribution. Melanin is synthesized in melanosomes of melanocytes, catalyzed by tyrosinase, melanogenic enzymes. Regarding the process of melanin synthesis, melanosomal pH is considered to play an important role, because it has been reported to differ between Caucasian and Black melanocytes. OBJECTIVE: Although polymethoxyflavone (PMF) has many beneficial effects, it has not been reported which PMF suppresses melanogenesis...

A strong version of scientism, such as that of Alex Rosenberg, says, roughly, that natural science reliably delivers rational belief or knowledge, whereas common sense sources of belief, such as moral intuition, memory, and introspection, do not. In this paper I discuss ten reasons that adherents of scientism have or might put forward in defence of scientism. The aim is to show which considerations could plausibly count in favour of scientism and what this implies for the way scientism ought to be formulated...

#18
Sho Yokoyama, Tsubasa S Matsui, Shinji Deguchi
Microcontact printing (μCPr) is one of the most popular techniques used for cell micropatterning. In conventional μCPr, a polydimethylsiloxane (PDMS) stamp with microfeatures is used to adsorb extracellular matrix (ECM) proteins onto the featured surface and transfer them onto particular areas of a cell culture substrate. However, some types of functional proteins other than ECM have been reported to denature upon direct adsorption to hydrophobic PDMS. Here we describe a detailed protocol of an alternative technique--microcontact peeling (μCPe)--that allows for cell micropatterning while circumventing the step of adsorbing proteins to bare PDMS...

The present study was carried out to know the sorption mechanism of Pb (II) and Ni (II) in aqueous solution using pea peels under the influence of sorbent dose, pH, temperature, initial metal ion concentration and contact time. SEM and FTIR were used for characterization of pea peels. The study showed that solution pH affects sorption process and the optimum pH for Pb (II) was 6.0 while for that of Ni (II) was 7.0. Pseudo-second order kinetic model was found to be the most suitable one to explain the kinetic data not only due to high value of R(2) (>0...
