Les As. examinent l'architecture des projections etendues des verbes et des noms dans les langues scandinaves continentales, c-a-d le danois, le norvegien et le suedois. En particulier, ils apportent des preuves concernant la courte montee des verbes et des noms respectivement dans le SV et le SN, et la montee du verbe du syntagme verbal au syntagme flexionnel. En outre, ils soulignent un fort parallelisme entre ces projections, dans la mesure ou les adverbes circonstanciels ont la meme position dans le SV que les adjectifs attributifs dans le SN
Domain propagation in He-ion-bombarded magnetic wires with opposite exchange bias

Exchange-biased IrMn/CoFe full films are magnetically structured with He-ion bombardment into stripes with antiparallel-aligned loop shift. The patterning results in a two-step magnetization loop corresponding to two regions of oppositely aligned exchange bias. The longitudinal magnetization reversal through head-on domain-wall motion and partial penetration of magnetization from neighboring strips is highly asymmetric involving ripplelike domain structures and incoherent rotation of magnetization. In addition, Neel-wall-like structures with a preferred sense of rotation are formed at the edges of the strips. Along the transverse direction the reversal is dominated by the switching of the magnetic border structures between the strips. Complicated domain patterns are generated under other external field angles.
Copper Efflux System Required in Murine Lung Infection by Haemophilus influenzae Composed of a Canonical ATPase Gene and Tandem Chaperone Gene Copies

Copper is an essential micronutrient but is toxic at high concentrations. In Haemophilus influenzae mechanisms of copper resistance and its role in pathogenesis are unknown; however, our previous genetic screen by transposon insertion-site sequencing implicated a putative cation transporting ATPase (copA) in survival in a mouse lung infection model. ABSTRACT Copper is an essential micronutrient but is toxic at high concentrations. In Haemophilus influenzae mechanisms of copper resistance and its role in pathogenesis are unknown; however, our previous genetic screen by transposon insertion-site sequencing implicated a putative cation transporting ATPase (copA) in survival in a mouse lung infection model. Here, we demonstrate that H. influenzae copA (HI0290) is responsible for copper homeostasis involving the merR-type regulator, cueR, as well as six tandem copies of the metallochaperone gene, copZ. Deletion of the ATPase and metallochaperone genes resulted in increased sensitivity to copper but not to cobalt, zinc, or manganese. Nontypeable H. influenzae (NTHi) clinical isolate NT127 has the same locus organization but with three copies of copZ. We showed that expression of the NTHi copZA operon is activated by copper under the regulatory control of CueR. NTHi single copA and copZ mutants and, especially, the double deletion copZA mutant exhibited decreased copper tolerance, and the ΔcopZA mutant accumulated 97% more copper than the wild type when grown in the presence of 0.5 mM copper sulfate. Mutants of NT127 deleted of the ATPase (copA) alone and deleted of both the ATPase and chaperones (copZ1-3) were 4-fold and 20-fold underrepresented compared to the parent strain during mixed-infection lung challenge, respectively. Complementation of cop locus deletion mutations restored copper resistance and virulence properties. NTHi likely encounters copper as a host defense mechanism during lung infection, and our results indicate that the cop system encodes an important countermeasure to alleviate copper toxicity.

The impact of child mortality on fertility in South Africa: Do child support grants and antiretroviral treatment matter?

This paper investigates the effect of under-five mortality, child support grant (CSG) coverage and the rollout of antiretroviral therapy (ART) on fertility in South Africa. The study employs the quality-quantity trade-off framework to analyse the direct and indirect factors affecting fertility using the two stage least squares fixed effects instrumental variable approach. The analysis uses balanced panel data covering nine provinces from 2001–2016. This period was characterised by significant increases in the child support grant coverage and ART coverage. Furthermore, this period was characterised by a significant decline in the under-five mortality rate. We find no evidence to support the hypothesis that increases in the CSG coverage are associated with an increase in fertility. This finding aligns with previous literature suggesting that there are no perverse incentives for childbearing associated with the child support grant. On the other hand, results indicate that an increase in ART coverage is associated with an increase in fertility. Results also show that a decrease in under-five mortality is associated with a decline in fertility over the sample period. HIV prevalence, education, real GDP per capita, marriage prevalence and contraceptive prevalence are also important determinants of fertility in South Africa. Although the scale up of ART has improved health outcomes, it also appears to have increased fertility in HIV-positive women. The ART programme should therefore be linked with further family planning initiatives to minimise unintended pregnancies.
Single proton LET characterization with the Timepix detector and artificial intelligence for advanced proton therapy treatment planning

Objective. Protons have advantageous dose distributions and are increasingly used in cancer therapy. At the depth of the Bragg peak range, protons produce a mixed radiation field consisting of low- and high-linear energy transfer (LET) components, the latter of which is characterized by an increased ionization density on the microscopic scale associated with increased biological effectiveness. Prediction of the yield and LET of primary and secondary charged particles at a certain depth in the patient is performed by Monte Carlo simulations but is difficult to verify experimentally. Approach. Here, the results of measurements performed with Timepix detector in the mixed radiation field produced by a therapeutic proton beam in water are presented and compared to Monte Carlo simulations. The unique capability of the detector to perform high-resolution single particle tracking and identification enhanced by artificial intelligence allowed to resolve the particle type and measure the deposited energy of each particle comprising the mixed radiation field. Based on the collected data, biologically important physics parameters, the LET of single protons and dose-averaged LET, were computed. Main results. An accuracy over 95% was achieved for proton recognition with a developed neural network model. For recognized protons, the measured LET spectra generally agree with the results of Monte Carlo simulations. The mean difference between dose-averaged LET values obtained from measurements and simulations is 17%. We observed a broad spectrum of LET values ranging from a fraction of keV μm−1 to about 10 keV μm−1 for most of the measurements performed in the mixed radiation fields. Significance. It has been demonstrated that the introduced measurement method provides experimental data for validation of LETD or LET spectra in any treatment planning system. The simplicity and accessibility of the presented methodology make it easy to be translated into a clinical routine in any proton therapy facility.
Comparison of long-term quality of life between Billroth-I and Roux-en-Y anastomosis after distal gastrectomy for gastric cancer: a randomized controlled trial

Abstract Background: The results of studies comparing Billroth-I (B-I) with Roux-en-Y (R-Y) reconstruction on the quality of life (QoL) are still inconsistent. The aim of this trial was to compare the long-term QoL of B-I with R-Y anastomosis after curative distal gastrectomy for gastric cancer. Methods: A total of 140 patients undergoing curative distal gastrectomy with D2 lymphadenectomy in West China Hospital, Sichuan University from May 2011 to May 2014 were randomly assigned to the B-I group (N = 70) and R-Y group (N = 70). The follow-up time points were 1, 3, 6, 9, 12, 24, 36, 48, and 60 months after the operation. The final follow-up time was May 2019. The clinicopathological features, operative safety, postoperative recovery, long-term survival as well as QoL were compared, among which QoL score was the primary outcome. An intention-to-treat analysis was applied. Results: The baseline characteristics were comparable between the two groups. There were no statistically significant differences in terms of postoperative morbidity and mortality rates, and postoperative recovery between the two groups. Less estimated blood loss and shorter surgical duration were found in the B-I group. There were no statistically significant differences in 5-year overall survival (79% [55/70] of the B-I group vs. 80% [56/70] of the R-Y group, P = 0.966) and recurrence-free survival rates (79% [55/70] of the B-I group vs. 78% [55/70] of the R-Y group, P = 0.979) between the two groups. The scores of the global health status of the R-Y group were higher than those of the B-I group with statistically significant differences (postoperative 1 year: 85.4 ± 13.1 vs. 88.8 ± 16.1, P = 0.033; postoperative 3 year: 87.3 ± 15.2 vs. 92.8 ± 11.3, P = 0.028; postoperative 5 year: 90.9 ± 13.7 vs. 96.4 ± 5.6, P = 0.010), and the reflux (postoperative 3 year: 8.8 ± 12.9 vs. 2.8 ± 5.3, P = 0.001; postoperative 5 year: 5.1 ± 9.8 vs. 1.8 ± 4.7, P = 0.033) and epigastric pain (postoperative 1 year: 11.8 ± 12.7 vs. 6.1 ± 8.8, P = 0.008; postoperative 3 year: 9.4 ± 10.6 vs. 4.6 ± 7.9, P = 0.006; postoperative 5 year: 6.0 ± 8.9 vs. 2.7 ± 4.6, P = 0.022) were milder in the R-Y group than those of the B-I group at the postoperative 1, 3, and 5-year time points. Conclusions: Compared with B-I group, R-Y reconstruction was associated with better long-term QoL by reducing reflux and epigastric pain, without changing survival outcomes.

Spontaneous dark formation of OH radicals at the interface of aqueous atmospheric droplets

Significance Recent studies suggest that reactions that do not usually occur in bulk solution can occur spontaneously in small water droplets, possibly due to the naturally formed electric field at the air–water interface. We explore the atmospheric significance of this process by demonstrating efficient spontaneous production of interfacial hydroxyl radicals (OH) from aqueous droplets under ambient conditions. This interfacial OH production does not involve precursors or catalysts, such as light or heat, and is likely the largest aqueous OH source in atmospheric droplets at nighttime. The ubiquity of aqueous aerosols and cloud droplets and their possibly strong OH-producing capability suggests that we have to rethink atmospheric multiphase oxidation chemistry.
Delpinium uncinatum mediated green synthesis of AgNPs and its antioxidant, enzyme inhibitory, cytotoxic and antimicrobial potentials

Green synthesis of nanoparticles is becoming a method of choice for biological research due to its environmentally benign outcomes, stability and ease of synthesis. In this study, silver nanoparticles (AgNPs) were synthesized using stem (S-AgNPs), root (R-AgNPs) and mixture of stem and root (RS-AgNPs) of Delphinium uncinatum. The synthesized nanoparticles were characterized by standardized techniques and evaluated for their antioxidant, enzyme inhibition, cytotoxic and antimicrobial potentials. The AgNPs exhibited efficient antioxidant activities and considerable enzyme inhibition potential against alpha amylase, acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) enzymes. S-AgNPs showed strong cytotoxicity against human hepato-cellular carcinoma cells (HepG2) and high enzyme inhibitory effect (IC50 values 27.5μg/ml for AChE and 22.60 μg/ml for BChE) compared to R-AgNPs and RS-AgNPs. RS-AgNPs showed significant inhibition of Klebsiella pneumoniae and Aspergillus flavus and exhibited higher biocompatibility (<2% hemolysis) in human red blood cells hemolytic assays. The present study showed that biologically synthesized AgNPs using the extract of various parts of D. uncinatum have strong antioxidant and cytotoxic potentials.
Cerebrospinal Fluid Flow and Brain Motion in Chiari I Malformation: Past, Present, and Future

Cranio‐spinal volume and pressure changes associated with the cardiac‐cycle and respiration are altered in Chiari I malformation (CMI) due to obstruction of cerebrospinal fluid (CSF) flow at the foramen magnum. With the introduction of motion‐sensitive MRI sequences, it was envisioned that these could provide noninvasive information about volume–pressure dynamics at the cranio‐cervical junction in CMI hitherto available only through invasive pressure measurements. Since the early 1990s, multiple studies have assessed CSF flow and brain motion in CMI. However, differences in design and varied approaches in the presentation of results and conclusions makes it difficult to fully comprehend the role of MR imaging of CSF flow and brain motion in CMI. In this review, a cohesive summary of the current status of MRI assessment of CSF flow and brain motion in CMI is presented. Simplified versions of the results and conclusions of previous studies are presented by dividing the studies in distinct topics: 1) comparing CSF flow and brain motion between healthy subjects (HS) and CMI patients (before and after surgery), 2) comparing CSF flow and brain motion to CMI severity and symptoms, and 3) comparing CSF flow and brain motion in CMI with and without syringomyelia. Finally, we will discuss our vision of the future directions of MR imaging in CMI patients.
The SCARE 2023 guideline: updating consensus Surgical CAse REport (SCARE) guidelines

Background: The Surgical CAse REport (SCARE) guidelines were first published in 2016 as a tool for surgeons to document and report their surgical cases in a standardised and comprehensive manner. However, with advances in technology and changes in the healthcare landscape, it is important to revise and update these guidelines to ensure they remain relevant and valuable for surgeons. Materials and methods: The updated guidelines were produced through a Delphi consensus exercise. Members of the SCARE 2020 guidelines Delphi group, editorial board members, and peer reviewers were invited to participate. Potential contributors were contacted by e-mail. An online survey was completed to indicate their agreement with the proposed changes to the guideline items. Results: A total of 54 participants were invited to participate and 44 (81.5%) completed the survey. There was a high degree of agreement among reviewers, with 36 items (83.7%) meeting the threshold for inclusion. Conclusion: Through a completed Delphi consensus exercise we present the SCARE 2023 guidelines. This will provide surgeons with a comprehensive and up-to-date tool for documenting and reporting their surgical cases while highlighting the importance of patient-centred care.
Psychometric Properties of the Patient Activation Measure in Family Caregivers of Patients With Chronic Illnesses

Background The Patient Activation Measure (PAM) is used clinically and in research to measure an individual’s knowledge, skills, and confidence related to their health management engagement. Despite the use of “patient” in the title, the instrument can be used in nonpatient populations. A group at high risk for low activation concerning their own health is family caregivers of patients with chronic illnesses. The psychometric properties of the PAM have not been established in family caregivers. Objectives This study aimed to examine the psychometric properties of the PAM 10-item version (PAM-10) in a sample of family caregivers of patients with chronic illnesses. Our focus was on family caregivers’ health activation of their own healthcare needs. Methods We evaluated the internal consistency reliability of the PAM-10 in a sample of 277 family caregivers. Item-total correlations and interitem correlations were used to assess item homogeneity. Construct validity of the PAM-10 was examined using exploratory factor analysis and testing hypotheses on known relationships. Results The PAM-10 demonstrated adequate internal consistency. Item-total correlation coefficients and interitem correlation coefficients were acceptable. Construct validity of the instrument was supported. Factor analysis yielded two factors that explained 62.3% of the variance in the model. Lower levels of depressive symptoms were significantly associated with better activation, providing evidence of construct validity. Caregivers with high activation levels were significantly more likely to engage in and adhere to self-care behaviors such as regular exercise, eating a healthy diet, and engaging in stress reduction strategies. Discussion This study demonstrated that the PAM-10 is a reliable and valid measure for family caregivers of patients with chronic illnesses to measure caregivers’ health activation of their own healthcare needs.
The correlation between women’s various gynaecological diseases to ovarian cancer in Sulaimaniyah City, Iraq

Objective To assess the relationship between benign gynaecological disorders and ovarian cancer (OC). Methods This retrospective observational study enrolled female patients with histologically-confirmed primary OC. Clinical and demographic data were collected using a questionnaire. Blood samples were analysed for tumour biomarker levels including cancer antigen (CA)-125, CA19-9, carcinoembryonic antigen, β human chorionic gonadotropin (β-hCG) and lactate dehydrogenase (LDH) using enzyme-linked immunosorbent assays. Results A total of 100 female patients were enrolled in the study. Of these, 44 patients had simple ovarian cysts (44%), 22 had uterine fibroids (22%), 15 had adenomyosis (15%), 13 had pelvic inflammatory disease (13%) and six had endometriosis (6%). There was a significant association between high grade serous OC histology with both benign ovarian and uterine diseases. There was a significant association between both adenomyosis and uterine fibroids and high grade OC. There was also a significant association between endometriosis and stages III/IV OC. With regard to tumour biomarkers, there was a significant association between β-hCG and LDH biomarkers and benign uterine tumours. Conclusion Benign gynaecological diseases are accompanied by the high risk of the development of OC. Common benign gynaecological diseases associated with OC were uterine fibroids and adenomyosis.
Base excision repair of the N-(2-deoxy-d-erythro-pentofuranosyl)-urea lesion by the hNEIL1 glycosylase

Abstract The N-(2-deoxy-d-erythro-pentofuranosyl)-urea DNA lesion forms following hydrolytic fragmentation of cis-5R,6S- and trans-5R,6R-dihydroxy-5,6-dihydrothymidine (thymine glycol, Tg) or from oxidation of 7,8-dihydro-8-oxo-deoxyguanosine (8-oxodG) and subsequent hydrolysis. It interconverts between α and β deoxyribose anomers. Synthetic oligodeoxynucleotides containing this adduct are efficiently incised by unedited (K242) and edited (R242) forms of the hNEIL1 glycosylase. The structure of a complex between the active site unedited mutant CΔ100 P2G hNEIL1 (K242) glycosylase and double-stranded (ds) DNA containing a urea lesion reveals a pre-cleavage intermediate, in which the Gly2 N-terminal amine forms a conjugate with the deoxyribose C1′ of the lesion, with the urea moiety remaining intact. This structure supports a proposed catalytic mechanism in which Glu3-mediated protonation of O4′ facilitates attack at deoxyribose C1′. The deoxyribose is in the ring-opened configuration with the O4′ oxygen protonated. The electron density of Lys242 suggests the ‘residue 242-in conformation’ associated with catalysis. This complex likely arises because the proton transfer steps involving Glu6 and Lys242 are hindered due to Glu6-mediated H-bonding with the Gly2 and the urea lesion. Consistent with crystallographic data, biochemical analyses show that the CΔ100 P2G hNEIL1 (K242) glycosylase exhibits a residual activity against urea-containing dsDNA.
The value of NT-pro-brain natriuretic peptide and left ventricular ejection fraction for prediction of premature ventricular complexes burden.

OBJECTIVE We aimed to investigate the relation of NT-pro BNP level and left ventricular ejection fraction with premature ventricular complex burden. PATIENTS AND METHODS A total of 94 patients with PVC burden > 5% (age 45.9+12.9 years, 53 males, 41 females) were included in the study. The primary outcome was PVC burden % and main prognostic factors were LVEF% and NT-Pro BNP level. Gender, age, DM, HTN, presence of symptoms, symptom duration and heart rate were used as adjustment predictor variables. We created four different linear multivariable models to compare performance measures of prognostic factors: Model-1 has gender, age, DM, HTN, symptoms and heart rate, while LVEF has been added in addition to model-1 in model-2. Model-3 included NT-Pro-BNP alongside model-1 variables, while model-4 included both LVEF and NT-Pro-BNP variables in addition to model-1 variables. Accordingly, we compare the performance (R2, likelihood ratio X2) of models. RESULTS The median PVC burden was 18% (IQR; 11-27). When model-1 consisting of gender, age, DM, HTN, presence of symptoms, symptomS duration and heart rate and model-2 consisting of LVEF in addition to variables of model-1 were compared, it was observed that both LRX2 and R2 values improved (likelihood ratio test p-value=0.013). Model-1 compared with model-3 which consisting of NT-pro BNP in addition to variables of model-1, and it was observed that both LRX2 and R2 values improved (likelihood ratio test p-value=0.008). However, when compared to model-1, the most significant improvement was observed in both LRX2 and R2 values in model-4 consisting of model-1 plus NT-Pro-BNP and LVEF (likelihood ratio test p-value <0.001). CONCLUSIONS We determined that NT-pro-BNP levels and LVEF could predict PVC burden in patients. Higher levels of NT-pro-BNP and lower LVEF values were associated with increased PVC burden.
