Adaptation of Maize to Temperate Climates: Mid-Density Genome-Wide Association Genetics and Diversity Patterns Reveal Key Genomic Regions, with a Major Contribution of the Vgt2 (ZCN8) Locus

The migration of maize from tropical to temperate climates was accompanied by a dramatic evolution in flowering time. To gain insight into the genetic architecture of this adaptive trait, we conducted a 50K SNP-based genome-wide association and diversity investigation on a panel of tropical and temperate American and European representatives. Eighteen genomic regions were associated with flowering time. The number of early alleles cumulated along these regions was highly correlated with flowering time. Polymorphism in the vicinity of the ZCN8 gene, which is the closest maize homologue to Arabidopsis major flowering time (FT) gene, had the strongest effect. This polymorphism is in the vicinity of the causal factor of Vgt2 QTL. Diversity was lower, whereas differentiation and LD were higher for associated loci compared to the rest of the genome, which is consistent with selection acting on flowering time during maize migration. Selection tests also revealed supplementary loci that were highly differentiated among groups and not associated with flowering time in our panel, whereas they were in other linkage-based studies. This suggests that allele fixation led to a lack of statistical power when structure and relatedness were taken into account in a linear mixed model. Complementary designs and analysis methods are necessary to unravel the architecture of complex traits. Based on linkage disequilibrium (LD) estimates corrected for population structure, we concluded that the number of SNPs genotyped should be at least doubled to capture all QTLs contributing to the genetic architecture of polygenic traits in this panel. These results show that maize flowering time is controlled by numerous QTLs of small additive effect and that strong polygenic selection occurred under cool climatic conditions. They should contribute to more efficient genomic predictions of flowering time and facilitate the dissemination of diverse maize genetic resources under a wide range of environments.
Erosion pattern on heating plates for regenerative air pre-heaters

The paper covers erosion phenomena on heating plates in regenerative air pre-heaters. The erosion pattern due to the ash laden flue-gas are significantly influenced by the heating plate design. The investigations were carried out for different erosion stages, i.e. 20%, 30% and 40% mass loss of the heating plate material. The tests show that the erosion characteristics are dependent on the profile design. Profiles with additional The highest erosion could be found on profiles with additional disturbances perpendicular to the flow direction. It became also visible that the undulated plates are much more damaged by the ash particles then the notched ones.
Primary angioplasty and stenting may be superior to thrombectomy for acute atherosclerotic large-artery occlusion

Objective The objective of this article is to compare the effectiveness of primary angioplasty and/or stenting with stent retriever thrombectomy in acute anterior large-vessel occlusion due to atherosclerotic disease. Methods Patients were retrospectively reviewed from the endovascular treatment for acute anterior circulation ischemic stroke registry. Patients with large-vessel occlusions due to atherosclerosis were selected. We evaluated modified Rankin Scale (mRS) score at 90 days, modified thrombolysis in cerebral infarction (mTICI) score immediately post-procedure, and symptomatic and asymptomatic intracranial hemorrhage within 72 hours. Results Of 302 patients with acute anterior circulation occlusion due to atherosclerotic disease, 269 were treated with stent retriever thrombectomy as first-line therapy and 33 with angioplasty and/or stenting. Patients who received primary angioplasty treatment showed favorable independent outcome at 90 days (69.7% (23/33) vs 47.6% (128/269), p = 0.02) and lower rate of asymptomatic intracranial hemorrhage (9.1% (3/23) vs 30.5% (82/269), p = 0.01). Recanalization immediately post procedure did not differ (78.8%% (26/33) vs 86.2% (232/269), p = 0.29). Primary angioplasty therapy (OR, 0.27; 95% confidence interval (CI): 0.08–0.90; p = 0.03) and small baseline infarct (OR 0.36: 0.16–0.82; p = 0.02) were protective factors against poor functional outcome, while old age (OR 1.04:1.01–1.07; p = 0.006), severe neurological deficits (OR 3.76: 2.00–7.07; p < 0.001), and high glucose (OR 1.11: 1.01–1.23; p = 0.03) were associated with poor prognosis. Conclusions Patients with acute anterior circulation large-vessel occlusion due to atherosclerosis may benefit from urgent angioplasty and/or stenting as first-line therapy. Randomized controlled trials are warranted.
INTERNAL CURING IMPROVES CONCRETE PERFORMANCE THROUGHOUT ITS LIFE

ı SEPTEMBER/OCTOBER 2009 Introduction In recent years, the technology of internal curing has been steadily progressing from laboratory studies to fi eld application. Prominent examples of fi eld applications include a railway transit yard in Texas [1], Texas state highway 121 [2], and bridge decks in Ohio [3] and New York. A winter 2006 Concrete InFocus article focused on enhancing high performance concrete through internal curing [4]. More recent studies at Purdue University [5-8] and the National Institute of Standards and Technology (NIST) [9, 10] have indicated that internal curing with pre-wetted fi ne lightweight aggregates positively impacts a variety of aspects of concrete performance from its fresh state throughout its life cycle, from cradle to grave. Results from these studies are summarized in this paper.
Incidence and risk factors of intracranial aneurysm: A national cohort study in Korea

Background Estimations of the intracranial aneurysm incidence require long-term follow-up of a relatively large at-risk population; as a result, the incidence remains largely unknown. Aims To investigate the national incidence of intracranial aneurysm in a Korean population. Methods After excluding 18,604 potential subjects with a previous history of stroke (I6x.x), 998,216 subjects were included in this observational cohort. The primary endpoint was the earliest date of diagnosis of either unruptured intracranial aneurysm (UIA; I67.1) or subarachnoid hemorrhage (SAH; I60.x). We collected anthropometric data, blood pressure measurements, laboratory data, and smoking, drinking, and physical exercise habits of 132,355 subjects for whom healthcare screening data were available. Factors influencing intracranial aneurysm were evaluated via multivariate Cox regression. Results The overall observation size was 8,792,214 person-years. During follow-up, 4346 subjects were diagnosed with intracranial aneurysm (SAH, 1960; UIA, 2386). The crude incidence of intracranial aneurysm was 49.4/100,000 person-years. The hazard ratio for women was 1.56 (p < 0.01), and older subjects had an increased hazard ratio. Subjects with hypertension had an approximately 1.5-fold higher risk of intracranial aneurysm. A history of heart disease and family history of stroke were associated with respective hazard ratios of 2.08 and 1.77. Conclusions In this Korean population study, the standardized incidence of intracranial aneurysm was 52.2/100,000 person-years. Older age, female sex, hypertension, history of heart disease, and family history of stroke were independent risk factors for intracranial aneurysm.
Fungal Infections in Immunosuppressed Patients

Fungal infections, also called mycoses, are important causes of morbidity and mortality in humans. Some fungal infections are endemic, and these infections are usually caused by fungi that are present in the environment and whose spores enter humans. Other fungal infections are said to be opportunistic because the causative agents cause mild or no disease in healthy individuals but may infect and cause severe disease in immunodeficient persons. The human airway is continuously open to the nonsterile environment where fungal spores have the potential to reach lung tissue and produce disease. In the immunocompromised host, many fungi, including species of fungi typically considered nonpathogenic, have the potential to cause serious morbidity and mortality. Over the last several decades the advent of the human immunodeficiency virus (HIV) epidemic and the increasing use of immunosuppressive drugs for serious medical conditions have dramatically increased the number of persons who are severely immunocompromised. In addition, the range and diversity of fungi that cause disease have broadened. Although Candida and Aspergillus species continue to be the fungal pathogens that most frequently cause invasive fungal disease in immunocompromised persons overall, infections due to previously uncommon hyaline and dematiaceous filamentous fungi are being reported with increasing frequency. This is significant because, despite marked advances in antifungal therapy, infections caused by opportunistic fungal infections (rare and emerging) continue to be associated with high morbidity, high mortality, and poor patient outcomes. This results from a combination of drug-resistant strains, lack of robust clinical studies evaluating treatments, and severe underlying diseases in the patient [2].
Access of proteinase K to partially translocated nascent polypeptides in intact and detergent-solubilized membranes

We have used proteinase K as a probe to detect cytoplasmically and luminally exposed segments of nascent polypeptides undergoing transport across mammalian microsomal membranes. A series of translocation intermediates consisting of discrete-sized nascent chains was prepared by including microsomal membranes in cell-free translations of mRNAs lacking termination codons. The truncated mRNAs were derived from preprolactin and the G protein of vesicular stomatitis virus and encoded nascent chains ranging between 64 and 200 amino acid residues long. Partially translocated nascent chains of 100 amino acid residues or less were insensitive to protease digestion from the external surface of the membrane while longer nascent chains were susceptible to digestion by externally added protease. We conclude that the increased protease sensitivity of larger nascent chains is due to the exposure of a segment of the nascent polypeptide on the cytoplasmic face of the membrane. In contrast, low molecular weight nascent chains were remarkably resistant to protease digestion even after detergent solubilization of the membrane. The protease resistant behaviour of detergent solubilized nascent chains could be abolished by release of the polypeptide from the ribosome or by the addition of protein denaturants. We propose that the protease resistance of partially translocated nascent chains can be ascribed to components of the translocation apparatus that remain bound to the nascent chain after detergent solubilization of the membrane.
Relationships between radiation, clouds, and convection during DYNAMO

The relationships between radiation, clouds, and convection on an intraseasonal time scale are examined with data taken during the Dynamics of the Madden‐Julian Oscillation (MJO) field campaign. Specifically, column‐net, as well as vertical profiles of radiative heating rates, computed over Gan Island in the central Indian Ocean (IO) are used along with an objective analysis of large‐scale fields to examine three MJO events that occurred during the 3 month period (October to December 2011) over this region. Longwave (LW) and shortwave radiative heating rates exhibit tilted structures, reflecting radiative effects associated with the prevalence of shallow cumulus during the dry, suppressed MJO phase followed by increasing deep convection leading into the active phase. As the convection builds going into the MJO active phase, there are increasingly top‐heavy anomalous radiative heating rates while the column‐net radiative cooling rate progressively decreases. Temporal fluctuations in the cloud radiative forcing, being quite sensitive to changes in high cloudiness, are dominated by LW effects with an intraseasonal variation of ~0.4–0.6 K/d. While both the water vapor and cloud fields are inextricably linked, it appears that the tilted radiative structures are more related to water vapor effects. The intraseasonal variation of column‐net radiative heating enhances the convective signal in the mean by ~20% with a minimum in this enhancement ~10 days prior to peak MJO rainfall and maximum ~7 days after. This suggests that as MJO convective envelope weakens over the central IO, cloud‐radiative feedbacks help maintain the mature MJO as it moves eastward.
Use of Cytochrome c Oxidase Subunit I (COI) Nucleotide Sequences for Identification of the Korean Luciliinae Fly Species (Diptera: Calliphoridae) in Forensic Investigations

Blowflies, especially species belonging to the subfamily Luciliinae, are the first insects to lay eggs on corpses in Korea. Fast and accurate species identification has been a key task for forensic entomologists. Because conventional morphologic identification methods have many limitations with respect to forensic practice, molecular methods have been proposed to identify fly species of forensic importance. To this end, the authors amplified and sequenced the full length of the cytochrome c oxidase subunit I (COI) gene of the Luciliinae fly species collected in Korea. The results showed the COI sequences are instrumental in identifying Luciliinae fly species. However, when compared with previously reported data, considerable inconsistencies were noted. Hemipyrellia ligurriens data in this study differed significantly from two of the five pre-existing data. Two closely related species, Lucilia illustris and Lucilia caesar, showed an overlap of COI haplotypes due to four European sequences. The results suggest that more individuals from various geographic regions and additive nuclear DNA markers should be analyzed, and morphologic identification keys must be reconfirmed to overcome these inconsistencies.
MEG Evidence for Dynamic Amygdala Modulations by Gaze and Facial Emotions

Background Amygdala is a key brain region for face perception. While the role of amygdala in the perception of facial emotion and gaze has been extensively highlighted with fMRI, the unfolding in time of amydgala responses to emotional versus neutral faces with different gaze directions is scarcely known. Methodology/Principal Findings Here we addressed this question in healthy subjects using MEG combined with an original source imaging method based on individual amygdala volume segmentation and the localization of sources in the amygdala volume. We found an early peak of amygdala activity that was enhanced for fearful relative to neutral faces between 130 and 170 ms. The effect of emotion was again significant in a later time range (310–350 ms). Moreover, the amygdala response was greater for direct relative averted gaze between 190 and 350 ms, and this effect was selective of fearful faces in the right amygdala. Conclusion Altogether, our results show that the amygdala is involved in the processing and integration of emotion and gaze cues from faces in different time ranges, thus underlining its role in multiple stages of face perception.
Anti-EGFR monoclonal antibody panitumumab for the treatment of patients with metastatic colorectal cancer: an overview of current practice and future perspectives

ABSTRACT Introduction: Targeted agents alone or in combination with chemotherapy are current standard of treatment for metastatic colorectal cancer (mCRC). Panitumumab is a fully human monoclonal antibody which inhibits the epidermal growth factor receptor (EGFR). It is currently approved in combination with chemotherapy in first- and second-line and as a monotherapy in chemorefractory patients. RAS gene mutations confer resistance to anti-EGFR agents; thus, panitumumab is restricted to the treatment of RAS wild-type (WT) tumors. Areas covered: This review explores the available data on panitumumab and presents new perspectives on predictive markers of anti-EGFR efficacy including primary tumor sidedness and BRAF mutations. Other details covered include panitumumab’s mechanism of action, pharmacokinetics, pharmacodynamics and safety aspects of the therapy as well as mechanisms of secondary resistance and future prospects of treatment in different settings. Expert opinion: Panitumumab has significantly added to the treatment armamentarium for RAS WT mCRC. The effort spent in identifying predictive biomarkers of panitumumab efficacy has been of pivotal importance to development of the molecular selection of patients with mCRC. Primary and secondary resistance, however, still represent important issues. Novel strategies to overcome those issues are currently underway with promising results which highlight the potential use of panitumumab in combination with other targeted agents in the future.
Physical Activity and Mental Toughness in University Students of Tabriz University

The purpose of this study was to survey the mental toughness and physical activity among student university of Tabriz. Baecke physical activity questionnaire, mental thoughness48 and demographic questionnaire was distributed between students. 355 questionnaires were collected. Correlation, , multiple ANOVA and independent t-test was used for analyzing the hypotheses. The result showed that there was significant relationship between some of physical activity and mental toughness subscales. Two groups active and non-active were compared to find out the mental toughness differences, Student who obtained the 75% upper the physical activity questionnaire was active (n=97) and Student who obtained the 25% under the physical activity questionnaire was inactive group (n=95). The difference between active and non-active physically people showed that active student was significantly mentally toughness. It is expected that changes in physical activity levels significantly could be evidence of mental toughness changes, it should be noted that the other variables should not be ignored.
Intra-Abdominal Hypertension and Abdominal Compartment Syndrome after Abdominal Wall Reconstruction: Quaternary Syndromes?

Background and Aims: Reconstruction with reconstitution of the container function of the abdominal compartment is increasingly being performed in patients with massive ventral hernia previously deemed inoperable. This situation places patients at great risk of severe intra-abdominal hypertension and abdominal compartment syndrome if organ failure ensues. Intra-abdominal hypertension and especially abdominal compartment syndrome may be devastating systemic complications with systematic and progressive organ failure and death. We thus reviewed the pathophysiology and reported clinical experiences with abnormalities of intra-abdominal pressure in the context of abdominal wall reconstruction. Material and Methods: Bibliographic databases (1950–2015), websites, textbooks, and the bibliographies of previously recovered articles for reports or data relating to intra-abdominal pressure, intra-abdominal hypertension, and the abdominal compartment syndrome in relation to ventral, incisional, or abdominal hernia repair or abdominal wall reconstruction. Results: Surgeons should thus consider and carefully measure intra-abdominal pressure and its resultant effects on respiratory parameters and function during abdominal wall reconstruction. The intra-abdominal pressure post-operatively will be a result of the new intra-peritoneal volume and the abdominal wall compliance. Strategies surgeons may utilize to ameliorate intra-abdominal pressure rise after abdominal wall reconstruction including temporizing paralysis of the musculature either temporarily or semi-permanently, pre-operative progressive pneumoperitoneum, permanently removing visceral contents, or surgically releasing the musculature to increase the abdominal container volume. In patients without complicating shock and inflammation, and in whom the abdominal wall anatomy has been so functionally adapted to maximize compliance, intra-abdominal hypertension may be transient and tolerable. Conclusions: Intra-abdominal hypertension/abdominal compartment syndrome in the specific setting of abdominal wall reconstruction without other complication may be considered as a quaternary situation considering the classification nomenclature of the Abdominal Compartment Society. Greater awareness of intra-abdominal pressure in abdominal wall reconstruction is required and ongoing study of these concerns is required.
U1 snRNP Alteration and Neuronal Cell Cycle Reentry in Alzheimer Disease

The aberrancy of U1 small nuclear ribonucleoprotein (snRNP) complex and RNA splicing has been demonstrated in Alzheimer’s disease (AD). Importantly, the U1 proteopathy is AD-specific, widespread and early-occurring, thus providing a very unique clue to the AD pathogenesis. The prominent feature of U1 histopathology is its nuclear depletion and redistribution in the neuronal cytoplasm. According to the preliminary data, the initial U1 cytoplasmic distribution pattern is similar to the subcellular translocation of the spliceosome in cells undergoing mitosis. This implies that the U1 mislocalization might reflect the neuronal cell cycle-reentry (CCR) which has been extensively evidenced in AD brains. The CCR phenomenon explains the major molecular and cellular events in AD brains, such as Tau and amyloid precursor protein (APP) phosphorylation, and the possible neuronal death through mitotic catastrophe (MC). Furthermore, the CCR might be mechanistically linked to inflammation, a critical factor in the AD etiology according to the genetic evidence. Therefore, the discovery of U1 aberrancy might strengthen the involvement of CCR in the AD neuronal degeneration.
Western diets are not responsible for chronic acid retention: a critical analysis of organic acid and phosphate contribution

Abstract According to usual literature, the diet-dependent endogenous production of titratable acidity (TA) is contributed by sulphuric and phosphoric acids (NA) and by metabolizable acids (MAs), representing ‘net-endogenous acid production’ (NEAP). NEAP is mainly neutralised by diet-dependent salts of inorganic cations (), estimated in foods, faeces and urine from inorganic cation–anion difference (NB). It is claimed that urinary loss of organic acids’ anions, ‘’, induces metabolizable H+ ions’ retention. Since ‘’ is normally lost in urine as ‘’ or ‘’, no MA retention takes place. Therefore, in our approach, net acid production (NAP) reduces to endogenous sulphuric acidity only. Since in western diets (WDs) alkaline cations exceed inorganic anions (NB excess), acid excess from phosphorus is neutralized. Moreover, the renal reabsorption of ultra-filtered Pi takes place at ratios greater than ‘4/1’, which means that the kidney operates as a dietary Pi-dependent NB generator ( or ). Since, in standard WDs, H2SO4 generation is less than ‘’ production, the sulphuric acidity escaping the intestinal absorption is neutralized by and excreted as diet-dependent , without interfering in normal A/B status. Only when extreme acidifying diets are ingested, sulphuric acidity may exceed ‘’. In this case, the excess of sulphuric acidity production is neutralised by the intervention of urinary excretion, whose employment is normally restricted to prevent loss of ultra-filtered NB. Finally, the whole body NA balance (NAb(W)) is calculated from the difference ‘NAabs – NA(u)’, where abs = intestinal absorption and u = urinary excretion. Being ‘NAabs ≈ NA(u)’, NAb(W) approximates zero, confirming WDs as non-acidifying foods.
