Most vascular plants interact with arbuscular mycorrhizal fungi （AMF） and are thereby provided significant advantages in nutrient acquisition, especially phosphate. The widespread retention of this symbiosis in vascular plants is testament to its importance and ancient origins. This highlight focuses on the reports of two of the first genes identified through for- ward genetic screens for AMF symbiotic mutants： Required for Abuscular Mycorrhization 1 （RAM1） and RAM2, which respectively encode a GRAS transcription factor and a glyc- erol-3-phosphate acyl-transferase （GPAT） that are required for the formation of fungal entry structures （hyphopodia） on the root surface.

A close relationship is assumed to exist between historic preservation and architectural practice. This study explores the nature of this relationship by using evidence from scholarly literature, the job market, and architectural education. The examined literature contains many examples showing that the architecture field views historic preservation as an external interest. Evidence from the job market indicates that architecture employers are uninterested in historic preservation skills, and historic preservation employers are not looking for architecture skills. Architecture schools and accrediting organizations either disregard historic preservation or minimize its importance. Moreover, historic preservation is more closely related to environmental and behavioral studies than it is to the architectural field. The relationship between architecture and historic preservation is tenuous, strained, and based more on stereotypes than on actual evidence.

cancer is a systemic disease. In order to fully understand it, we must take a holistic view on how cancer interacts with its host. The brain monitors and responds to natural and aberrant signals arriving from the periphery, particularly those of metabolic or immune origin. As has been well described, a hallmark of cancer is marked disruption of metabolic and inflammatory processes. Depending on the salience and timing of these inputs, the brain responds via neural and humoral routes to alter whole-body physiology. These responses have consequences for tumor growth and metastasis, directly influencing patient quality of life and subsequent mortality. Additionally, environmental inputs such as light, diet, and stress, can promote inappropriate neural activity that benefits cancer. Here, I discuss evidence for brain-tumor interactions, with special emphasis on subcortical neuromodulator neural populations, and potential ways of harnessing this cross-talk as a novel approach for cancer treatment.

A na?ve solver is one approach that can be used to identify prospective solutions based on data on(or projected to be on) a blackboard Architecture’s blackboard. The na?ve solver approach doesn t implement heuristics or other techniques to determine what solution paths to attempt first. Instead, it runs the blackboard forward(simulating what would occur if data were gradually added to the blackboard at a faster-than-real time rate). The approach doesn t guarantee that an optimal solution will be found and will need to be run repetitively to create multiple solutions for comparison. This paper assesses the effect of pre-pruning the blackboard’s facts and rules to remove those that are not relevant(e.g., facts that cannot be asserted, rules that cannot be triggered) or which produce irrelevant facts and pruning actions that produce irrelevant facts(and/or trigger other similarly useless actions). It describes the blackboard implementation and its utility, explains the pruning process used and presents quantitative and qualitative assessment of the utility of pruning to a na?ve solver’s operations. This value is extrapolated to facilitate consideration of a more robust pruning process which also removes low-value facts, actions and rules in addition to those being removed due to their uselessness.

Introduction certain patients at low risk of clinically significant esophageal varices by baveno criteria can safely avoid screening esophagogastroduodenoscopy(EGD)[1,2].However,regardless of variceal status,the PREDEScI study suggests that earlier betablocker(bb)use in compensated disease with clinically significant portal hypertension by hepatic venous pressure gradient may result in benefit by delaying the time to decompensated cirrhosis[3,4].This carries significant ramifications for future clinical guidelines and decision-making for whom we decide to initiate bb.

The term Hereditary Non-Polyposis colorectal cancer （HNPcc） is a poor descriptor of the syndrome described by Lynch. Over the last decade, the term has been applied to heterogeneous groups of families meeting limited clinical criteria, for example the Amsterdam criteria. It is now apparent that not all Amsterdam criteria-positive families have the Lynch syndrome. The term HNPcc has also been applied to clinical scenarios in which cRcs with DNA microsateUite instability are diagnosed but in which there is no vertical transmission of an altered DNA mismatch repair （MMR） gene. A term that has multiple, mutually incompatible meanings is highly problematic, particularly when it may influence the management of an individual family. The Lynch syndrome is best understood as a hereditary predisposition to malignancy that is explained by a germline mutation in a DNA MMR gene. The diagnosis does not depend in an absolute sense on any particular family pedigree structure or age of onset of malignancy. Families with a strong family history of colorectal cancer that do not have Lynch syndrome have been grouped as ‘Familial colorectal cancer Type-X＇. The first step in characterizing these cancer families is to distinguish them from Lynch syndrome. The term HNPcc no longer serves any useful purpose and should be phased out.
