Caenorhabditis elegans neuroscientists are on track to describe the world’s first functional connectome. The work by Ohnishi et al (2011) is an excellent example of this effort. Characterizing glutamatergic transmission within the neural circuit controlling locomotion in thermal gradients, they found that two thermosensory neurons, AFD and AWC, transmitted glutamate signals of opposite polarity...

Changes in the environment cause both short-term and long-term changes in an animal's behavior. Here we show that specific sensory experiences cause changes in chemosensory receptor gene expression that may alter sensory perception in the nematode Caenorhabditis elegans. Three predicted chemosensory receptor genes expressed in the ASI chemosensory neurons, srd-1, str-2, and str-3, are repressed...

Sensory systems generally contain a number of neuronal subtypes that express distinct sensory receptor proteins. This diversity is generated through deterministic and stochastic cell fate choices, while maintaining the subtype often requires a distinct mechanism. In a study published in the February 1, 2009, issue of Genes & Development, Lesch and colleagues (pp. 345-358) describe a new transcr...

Brazilian soybean has undergone considerable economic growth. Its production depends on the demand for some inputs. One of these inputs is soil water supply, which can be made artificially or obtained by natural rainfall. Knowledge available capacity (AWC), total availability (TWA), poorly accessible and difficult to measure in field. This study aimed map AWC state Tocantins, based pedotransfer...

The socio-economic development of a country is highly dependent on water availability. Nowadays, increasing scarcity major global challenge. Continuing improvements in water-use efficiency are essential for cotton production sustainability. Reduced irrigation could be solution to shortage the arid climate without compromising yield. Therefore, two-year field study was conducted assess effect tw...

Abstract Introduction Incisional Hernia (IH) is a common complication of colorectal surgery. Given high recurrence rates and associated morbidity, emphasis must be on prevention IH. There an association between surgeon volume outcomes in hernia surgery, yet little evidence regarding impact the experience performing abdominal wall closure (AWC) IH rate. Our aim was to assess at 1 year following ...

BACKGROUND India shares the largest burden of under-nutrition in world. The aim of this study was to conduct follow-up assessment of under-nourished children attending anganwadi center (AWC). METHODS This was a retrospective cohort study conducted in 50 AWC of Tapi district. Total 529 children aged 1-6 years diagnosed as under-nourished before 1 year were included. Pre-structured questionnair...
