The Orthopaedic Workforce Is Not as Diverse as the Population It Serves: Where Are the Minorities and the Women?: AOA Critical Issues Symposium.

J Bone Joint Surg Am 2019 Apr;101(8):e31

Nth Dimensions, Chicago, Illinois.

The lack of sex and racial diversity of the physicians within the specialty of orthopaedic surgery was recognized decades ago, and formal steps to address these issues began in 1983 with the founding of the Ruth Jackson Orthopaedic Society and the J. Robert Gladden Orthopaedic Society. Despite the efforts of these organizations, the work of other interested groups, and the growing diversity in medical student demographics, physician diversity in orthopaedic surgery remains disproportionately poor relative to the populations that we serve as a specialty.

Changes in nitrogen functional genes in soil profiles of grassland under long-term grazing prohibition in a semiarid area.

Sci Total Environ 2019 Apr 3;673:92-101. Epub 2019 Apr 3.

State Key Laboratory of Soil Erosion and Dryland Farming on the Loess Plateau, Northwest A&F University, Yangling 712100, PR China. Electronic address:

Grazing prohibition has been used to restore degraded grassland ecosystems in semiarid areas; however, the impact of this measure on soil nitrogen (N) cycling is poorly understood. Furthermore, recent studies have tended to focus on the topsoil and ignored a steep gradient of nutrient accumulation with soil depth. Here, we investigated changes in N functional genes (NFGs) involved in organic N decomposition (chiA), archaeal and bacterial ammonia oxidation (amoA-AOA and amoA-AOB), respectively, denitrification (nirK and nirS), and N fixation (nifH) in soil profiles from a chronosequence of grazing prohibition (0, 10, 15, 25, and 35 years) in the semiarid grasslands of the Loess Plateau, China.

Genomic adaptation to eutrophication of ammonia-oxidizing archaea in the Pearl River estuary.

Environ Microbiol 2019 Mar 29. Epub 2019 Mar 29.

SZU-HKUST Joint PhD Program in Marine Environmental Science, Shenzhen University, Shenzhen, China.

Ammonia-oxidizing archaea (AOA) are ubiquitous in natural ecosystems, and they are responsible for a significant fraction of ammonia oxidation globally. Since the first AOA isolate was established a decade ago, molecular surveys of their environmental distribution [based primarily on amplicon sequencing of the amoA, which codes for the alpha subunit of ammonia monooxygenase (AMO)], show that their habitats are believed to range from marine to terrestrial environments. However, the mechanisms of adaptation underpinning to their habitat expansion remain poorly understood. Read More

Functional dominance and community compositions of ammonia-oxidizing archaea in extremely acidic soils of natural forests.

Appl Microbiol Biotechnol 2019 Mar 28. Epub 2019 Mar 28.

Laboratory of Environmental Microbiology and Toxicology, School of Biological Sciences, Faculty of Science, The University of Hong Kong, Pokfulam Road, Hong Kong, SAR, People's Republic of China.

Extremely acidic soils of natural forests in Nanling National Nature Reserve have been previously investigated and revisited in two successive years to reveal the active ammonia oxidizers. Ammonia-oxidizing archaea (AOA) rather than ammonia-oxidizing bacteria (AOB) were found more functionally important in the extremely acidic soils of the natural forests in Nanling National Nature Reserve. The relative abundances of Nitrosotalea, Nitrososphaera sister group, and Nitrososphaera lineages recovered by ammonia monooxygenase subunit A (amoA) transcripts were reassessed and compared to AOA communities formerly detected by genomic DNA.

Italian Age of Acquisition Norms for a Large Set of Words (ItAoA).

Front Psychol 2019 13;10:278. Epub 2019 Feb 13.

Department of General Psychology, University of Padua, Padua, Italy.

Age of acquisition (AoA) is an important psycholinguistic variable that affects the performance of healthy individuals and patients in a large variety of cognitive tasks. For this reason, it becomes more and more compelling to collect new AoA norms for a large set of stimuli in order to allow better control and manipulation of AoA in future research. An important motivation of the present study is to extend previous Italian norms by collecting AoA ratings for a much larger range of Italian words for which concreteness and semantic-affective norms are now available thus ensuring greater coverage of words varying along these dimensions.

Remarkable NO emissions by draining fallow paddy soil and close link to the ammonium-oxidizing archaea communities.

Sci Rep 2019 Feb 22;9(1):2550. Epub 2019 Feb 22.

Key Laboratory of Agro-ecological Processes in Subtropical Regions and Taoyuan Station of Agro-Ecology Research, Institute of Subtropical Agriculture, Chinese Academy of Sciences, Changsha, 410125, China.

Fallow paddies experience natural flooding and draining water status due to rainfall and evaporation, which could induce considerable nitrous oxide (NO) emissions and need to be studied specially. In this study, intact soil columns were collected from a fallow paddy field and the flooding-draining process was simulated in a microcosm experiment. The results showed that both NO concentrations in the soil and NO emission rates were negligible during flooding period, which were greatly elevated by draining the fallow paddy soil. Read More

Characterization of Multipath Effects in Indoor Positioning Systems by AoA and PoA Based on Optical Signals.

Sensors (Basel) 2019 Feb 21;19(4). Epub 2019 Feb 21.

Department of Electronics, University of Alcalá, Alcalá de Henares, 28801 Madrid, Spain.

In this paper, we characterize and measure the effects of the errors introduced by the multipath when obtaining the position of an agent by means of Indoor Positioning Systems (IPS) based on optical signal. These effects are characterized in Local Positioning Systems (LPSs) based on two different techniques: the first one by determining the Angle of Arrival (AoA) of the infrared signal (IR) to the detector; and the second one by working with the measurement of the Phase shift of signal Arrival from the transmitter to a receiver (PoA). We present the obtained results and conclusions, which indicate that using Position Sensitive Devices (PSD) the multipath effects for AoA have little impact on the measurement, while for PoA the positioning errors are very significant, making the system useless in many cases.

Nitrification inhibitors effectively target N O-producing Nitrosospira spp. in tropical soil.

Environ Microbiol 2019 Apr 14;21(4):1241-1254. Epub 2019 Mar 14.

Department of Microbial Ecology, Netherlands Institute for Ecology NIOO-KNAW, Wageningen, Netherlands.

The nitrification inhibitors (NIs) 3,4-dimethylpyrazole (DMPP) and dicyandiamide (DCD) can effectively reduce N O emissions; however, which species are targeted and the effect of these NIs on the microbial nitrifier community is still unclear. Here, we identified the ammonia oxidizing bacteria (AOB) species linked to N O emissions and evaluated the effects of urea and urea with DCD and DMPP on the nitrifying community in a 258 day field experiment under sugarcane. Using an amoA AOB amplicon sequencing approach and mining a previous dataset of 16S rRNA sequences, we characterized the most likely N O-producing AOB as a Nitrosospira spp. Read More

Long-term fertilization regimes change soil nitrification potential by impacting active autotrophic ammonia oxidizers and nitrite oxidizers as assessed by DNA stable isotope probing.

Environ Microbiol 2019 Apr 14;21(4):1224-1240. Epub 2019 Mar 14.

Jiangsu Provincial Key Lab for Organic Solid Waste Utilization, National Engineering Research Center for Organic-Based Fertilizers, Jiangsu Collaborative Innovation Center for Solid Organic Waste Resource Utilization, Nanjing Agricultural University, Nanjing, 210095, China.

Chemoautotrophic ammonia-oxidizers and nitrite-oxidizers are responsible for a significant amount of soil nitrate production. The identity and composition of these active nitrifiers in soils under different long-term fertilization regimes remain largely under-investigated. Based on that soil nitrification potential significantly decreased in soils with chemical fertilization (CF) and increased in soils with organic fertilization (OF), a microcosm experiment with DNA stable isotope probing was further conducted to clarify the active nitrifiers.

Nitric oxide acutely modulates hypothalamic and neurohypophyseal carbon monoxide and hydrogen sulphide production to control vasopressin, oxytocin and atrial natriuretic peptide release in rats.

J Neuroendocrinol 2019 Feb 12;31(2):e12686. Epub 2019 Feb 12.

Department of Physiology, Ribeirão Preto Medical School, University of São Paulo, Ribeirão Preto, Brazil.

Nitric oxide (NO) negatively modulates the secretion of vasopressin (AVP), oxytocin (OT) and atrial natriuretic peptide (ANP) induced by the increase in extracellular osmolality, whereas carbon monoxide (CO) and hydrogen sulphide (H S) act to potentiate it; however, little information is available for the osmotic challenge model about whether and how such gaseous systems modulate each other. Therefore, using an acute ex vivo model of hypothalamic and neurohypophyseal explants (obtained from male 6/7-week-old Wistar rats) under conditions of extracellular iso- and hypertonicity, we determined the effects of NO (600 μmol L sodium nitroprusside), CO (100 μmol L tricarbonylchloro[glycinato]ruthenium [II]) and H S (10 mmol L sodium sulphide) donors and nitric oxide synthase (NOS) (300 μmol L N -methyl-l-arginine [LNMMA]), haeme oxygenase (HO) (200 μmol L Zn(II) deuteroporphyrin IX 2,4-bis-ethylene glycol [ZnDPBG]) and cystathionine β-synthase (CBS) (100 μmol L aminooxyacetate [AOA]) inhibitors on the release of hypothalamic ANP and hypothalamic and neurohypophyseal AVP and OT, as well as on the activities of NOS, HO and CBS. LNMMA reversed hyperosmolality-induced NOS activity, and enhanced hormonal release by the hypothalamus and neurohypophysis, in addition to increasing CBS and hypothalamic HO activity. Read More

[Denitrification and Phosphorus Removal from Low C/N Urban Sewage Based on a Post-Partial Denitrification AOA-SBR Process].

Huan Jing Ke Xue 2019 Jan;40(1):360-368

School of Environmental Science and Engineering, Qingdao University, Qingdao 266071, China.

This study focuses on the investigation of the nitrogen (N) and phosphorus (P) removal characteristics of a combination of enhanced phosphorus removal (EBPR) with simultaneous partial nitrification endogenous denitrification (SPND) and post-partial denitrification process. An anaerobic/aerobic/anoxic (A/O/A) operated sequencing batch reactor (SBR) fed with urban sewage was optimized by regulating the aeration rate and anoxic time. Based on this optimization, deep-level nitrogen and phosphorus removals from low C/N urban sewage could be realized. Read More
