Huimei Hao, Shanshan Wang
Though important for a variety of medical procedures, general anesthesia is not a problem free. Some anesthetics have been suggested to affect a number of signals, which are associated with memory consolidation and cognition. In the present study, we attempted to investigate the molecular mechanism of anesthesia-regulated processes. We found that under hypothermic condition, anesthetic of isoflurane enhances various signals expression in hippocampus, including Hspd1, Actb, Mgst1, THBS4, Syp, C1QC, Serpine, Plat, and Ngf, which were related to cellular stress, neural plasticity responses, and hippocampal injury...

PURPOSE: Consolidation is a standard part of most post-distraction protocols. This study aims to determine whether the deliberate omission of a consolidation period following mandibular distraction (MD) in neonates with Pierre Robin sequence (PRS) affected the airway outcomes and complication rates. PATIENTS AND METHODS: A retrospective chart review of 28 neonates with PRS who underwent MD for severe airway obstruction between 2009 and 2014 was performed. Neonates were split into 2 cohorts: those with a very short or no consolidation (no consolidation group, n = 18) and those with a traditional consolidation period (consolidation group, n = 10)...

BACKGROUND: Conventional fronto-orbital advancement and distraction osteogenesis (DOG) have been used to treat craniosynostosis, both of which are considered effective. During the authors' practice, a phenomenon of frontal hyperostosis has been observed in the patients of craniosynostosis after DOG, which has yet to be reported in the literature. The purpose of this study is trying to identify the factors related to the phenomenon. MATERIALS AND METHODS: From 1997 to 2010, all patients of craniosynostosis undergoing DOG were reviewed...

Essential gene functions remain largely underexplored in bacteria. Clostridium cellulolyticum is a promising candidate for consolidated bioprocessing; however, its genetic manipulation to reduce the formation of less-valuable acetate is technically challenging due to the essentiality of acetate-producing genes. Here we developed a Cas9 nickase-assisted chromosome-based RNA repression to stably manipulate essential genes in C. cellulolyticum. Our plasmid-based expression of antisense RNA (asRNA) molecules targeting the phosphotransacetylase (pta) gene successfully reduced the enzymatic activity by 35% in cellobiose-grown cells, metabolically decreased the acetate titer by 15 and 52% in wildtype transformants on cellulose and xylan, respectively...

Caroline L Horton
The continuity hypothesis (1) posits that there is continuity, of some form, between waking and dreaming mentation. A recent body of work has provided convincing evidence for different aspects of continuity, for instance that some salient experiences from waking life seem to feature in dreams over others, with a particular role for emotional arousal as accompanying these experiences, both during waking and while asleep. However, discontinuities have been somewhat dismissed as being either a product of activation-synthesis, an error within the consciousness binding process during sleep, a methodological anomaly, or simply as yet unexplained...

Coccidioides spp. are saprophytic, dimorphic fungi that are endemic to arid climates, are capable of infecting many species, and result in diverse clinical presentations. An indoor-housed laboratory rhesus macaque presented with weight loss and decreased activity and appetite. During the diagnostic evaluation, a bronchiolar-alveolar pattern in the cranial lung lobes, consistent with bronchopneumonia, was noted on radiographs. Given the poor prognosis, the macaque was euthanized. Confirming the radiographic assessment, gross necropsy findings included multifocal to coalescing areas of consolidation in the right and left cranial lung lobes...

Ibrahim S Al-Busaidi, Cameron I Wells
Developing the clinical academic workforce of the future is a priority of international relevance. Despite a number of measures implemented to address this challenge, a small proportion of medical students engage in research. Lack of knowledge of available research opportunities, and difficulty finding projects and suitable mentors are key barriers to undergraduate medical research. To date, there is no consolidated source of information on undergraduate research training opportunities and their outcomes available to medical students in New Zealand...

Roger Ratcliff, Hans P A Van Dongen
Sleep deprivation adversely affects the ability to perform cognitive tasks, but theories range from predicting an overall decline in cognitive functioning because of reduced stability in attentional networks to specific deficits in various cognitive domains or processes. We measured the effects of sleep deprivation on two memory tasks, item recognition ("was this word in the list studied") and associative recognition ("were these two words studied in the same pair"). These tasks test memory for information encoded a few minutes earlier and so do not address effects of sleep deprivation on working memory or consolidation after sleep...

Development of vaccines that are both safe and effective remains a costly and time-consuming challenge. To accelerate the pace of development and improve the efficacy and safety of candidate vaccines for both existing and emerging infectious agents, we have employed a distributed development approach. This features the managed integration of individual expert groups having the requisite vaccine platforms, pre-clinical models, assays, skills and knowledge pertinent to a specific pathogen into a single, end-to-end development team capable of producing a new vaccine tailored to that particular agent...

Purpose While critical approaches have enriched research in proximate fields, their impact has been less marked in studies of healthcare management. In response, the 2016 Organizational Behaviour in Health Care Conference hosted its first-ever session dedicated to the emergent field of critical healthcare management studies (CHMSs). The purpose of this paper is to present five papers selected from that conference. Design/methodology/approach In this introductory paper, the authors frame the contributions as "green shoots" in a field of CHMS which contains four main furrows of activity: questioning the taken-for-granted; moving beyond instrumentalism; reflexivity and meanings in research; and challenging structures of domination (Kitchener and Thomas, 2016)...

The title compound, [IrCl(C12H8NO)2{(CH3)2SO}]·H3CCN or [IrCl(fppy)2(DMSO)]·H3CCN [where fppy is 4-(pyridin-2-yl)benzaldehyde and DMSO is dimethyl sulfoxide], is a mononuclear iridium(III) complex including two fppy ligands, a sulfur-coordinating DMSO ligand, and one terminal chloride ligand that define a distorted octa-hedral coordination sphere. The complex crystallizes from 1:1 DMSO-aceto-nitrile as an aceto-nitrile solvate. In the crystal, weak C-H⋯O and C-H⋯N hydrogen-bonding inter-actions between adjacent complexes and between the aceto-nitrile solvent and the complex consolidate the packing...

BACKGROUND: In cancer cells, autophagy can act as both tumor suppressor, when autophagic event eliminates cellular contends which exceeds the cellular capacity of regenerate promoting cell death, and as a pro-survival agent removing defective organelles and proteins and helping well-established tumors to maintain an accelerated metabolic state while still dealing with harsh conditions, such as inflammation. Many pathways can coordinate the autophagic process and one of them involves the transcription factors called PPARs, which also regulate cellular differentiation, proliferation and survival...

We measured ground displacements before and after the 2009 L'Aquila earthquake using multi-temporal InSAR techniques to identify seismic precursor signals. We estimated the ground deformation and its temporal evolution by exploiting a large dataset of SAR imagery that spans seventy-two months before and sixteen months after the mainshock. These satellite data show that up to 15 mm of subsidence occurred beginning three years before the mainshock. This deformation occurred within two Quaternary basins that are located close to the epicentral area and are filled with sediments hosting multi-layer aquifers...

The concept of epithelial-mesenchymal plasticity (EMP), which describes the dynamic flux within the spectrum of phenotypic states that invasive carcinoma cells may reside, is being increasingly recognised for its role in cancer progression and therapy resistance. The myriad of events that are able to induce EMP, as well as the more recently characterised control loops, results in dynamic transitions of cancerous epithelial cells to more mesenchymal-like phenotypes through an epithelial-mesenchymal transition (EMT), as well as the reverse transition from mesenchymal phenotypes to an epithelial one...

OBJECTIVE: Research is required in order to illustrate and detail the experiences of informal caregivers of patients with motor neurone disease (pwMND) to further advance the research base and to inform the development of future support structures and services. Due to the heterogeneous nature of caregiving for pwMND, one way in which this can be achieved is through a qualitative review. A qualitative thematic analysis of existing qualitative studies has not, to the best of the authors' knowledge, been previously undertaken...

Mechanical ventilation (MV) is critical in the management of many patients with the acute respiratory distress syndrome (ARDS). However, MV can also cause ventilator-induced lung injury (VILI). The selection of an appropriate tidal volume is an essential part of a lung-protective MV strategy. Since the publication of a large randomized clinical trial demonstrating the benefit of lower tidal volumes, the use of tidal volumes of 6 mL/kg predicted body weight (PBW, based on sex and height) has been recommended in clinical practice guidelines...

A number of Angelica species have been used in traditional systems of medicine to treat many ailments. Especially, essential oils (EOs) from the Angelica species have been used for the treatment of various health problems, including malaria, gynecological diseases, fever, anemia, and arthritis. EOs are complex mixtures of low molecular weight compounds, especially terpenoids and their oxygenated compounds. These components deliver specific fragrance and biological properties to essential oils. In this review, we summarized the chemical composition and biological activities of EOs from different species of Angelica...
