Effect of fertilization and genetic variation on susceptibility of Pinus radiata seedlings to Hylobius abietis damage

The effects of establishment fertilization and pine genotype on pine weevil (Hylobius abietis L.) damage was studied in a radiata pine (Pinus radiata D. Don) naturally infected familyfertilization genetic trial in Galicia (north- western Spain). Fertilization strongly increased both growth and H. abietis damage, especially when calcium phosphate was included in the fertilization treatment. Fertilized plants showed higher degree of debarking, greater leader loss, and higher mortality than unfertilized controls. Because of the greater leader loss, fertilization did not significantly increase the actual height (height of live stem) 1 year after planting. In contrast, after the second growing season, fertilized plants over- compensated for the weevil damage and reached greater height than the unfertilized controls. However, considering the ef- fects on survival and the stem deformities resulting from the leader losses, fertilization should be avoided (or delayed) in P. radiata plantations on clear-cut coniferous areas if the risk of H. abietis is high. Our results also indicate a strong ge- netic variation in H. abietis susceptibility within the Galician P. radiata breeding population. The high family-mean and the moderate individual-tree heritability estimates suggest that improving resistance to this pest by conventional breeding techniques is possible. The use of planting stock with improved resistance should be considered as another prophylactic measure to supplement the traditional methods employed against this pest.

The emotional eating and negative food relationship experiences of obese and overweight adults

ABSTRACT Overweight and obesity pose serious public health problems, affecting 68.8% of Americans. Previous research indicated that psychological factors played important roles in an individual’s motivation to consume food. In particular, emotional eating, defined as overeating in response to negative affect, has received particular attention as a risk factor for obesity. This study explored and addressed the emotional factors involved in the development of emotional eating. A total of 10 Midwestern American male and female adults, previously diagnosed as medically overweight and obese, were recruited via online and print advertisement using maximum variation and snowball sampling methods. Using a semi-structured, face-to-face interview format, participants shared their perspectives about the development and persistence of emotional eating. The interviews were transcribed and Atlas.ti software was used to assist in thematic analysis of emotional eating. Study results yielded themes, such as emotional triggers, food cravings, comfort from foods, mindless eating, and childhood experiences. Findings indicated that participants generally lacked emotional self-care, but desired to decrease their emotional eating behaviors. Implications are discussed to construct creative, evidence-based treatments for the overweight and obese emotional eaters.
Magnetic disorder in TbAl2 nanoparticles

The magnetic and thermal properties of TbAl2 nanosized alloys (diameters, 12 nm ≤ D ≤ ? > 20 nm) obtained by high-energy milling are characterised by specific heat, magnetisation and neutron scattering. The specific heat shows that the λ-anomaly at Curie temperature vanishes when the milling time reaches 300 h and its field variation shows a broad peak around 70 K disclosing a disordered magnetic state. The thermal variation of magnetization follows a Bloch process with a decrease of the stiffness constant and a faster demagnetisation with a quadratic exponent instead of the bulk ordinary T 3 / 2 ? > -dependence. The magnetic moment reduction in the nanosized alloys follows a 1/D dependence, remarking the role of disordered moment surface. The Rietveld analysis of the neutron diffraction patterns indicates a collinear ferromagnetic structure, with a reduction of the Tb-magnetic moment when decreasing the particle size. The temperature dependent overall magnetic signal of nanoparticles is derived from small-angle neutron scattering. A magnetic nanoparticle structure with an ordered ferromagnetic core and a disordered surface layer is proposed.
Real-World Management of Trabectedin/Pegylated Liposomal Doxorubicin in Platinum-Sensitive Recurrent Ovarian Cancer Patients: A National Survey

Background Trabectedin (T) plus pegylated liposomal doxorubicin (PLD) is approved for treatment of platinum-sensitive recurrent ovarian cancer (ROC). Despite the recommendations and guidelines, variations in managing T/PLD administration in routine clinical practice cannot be excluded. We aimed at setting up an Italian survey collecting data about management of T/PLD administration in ROC patients. Methods We carried out the development of a questionnaire-based survey on routine clinical practice in the management of ROC patients administered T/PLD. The survey registered the physicians’ approach to modification/discontinuation of treatment, type of modifications, reasons why, and so on. The survey was transmitted to medical oncologists and gynecologic oncologists practicing in national centers/institutions. Results Fifty-eight Italian centers/institutions returned the compiled questionnaire; participants practiced at community cancer centers or hospitals (56.9%), academic institutions (36.2%), and other settings (private clinics, etc) (6.9%). There was no statistically significant difference in the distribution of practice setting according to geographic areas. Most responders were medical oncologists (84.5%) and were members (82.8%) of at least 1 scientific society or cooperative group. Almost 31.5% of responders reported interruption of the whole treatment, mostly because of toxicity (41.2%), followed by patients’ choice (29.4%), or achievement of clinical benefit (23.5%). Dose reduction was referred by 47.4% of responders. Reduction of dose for both drugs was referred by 88.5% of responders, and the extent of dose reduction ranged between 10% and 30%. Conclusions This survey highlights the gaps in transposing evidence-based or consensus guidelines in the real-world management of T/PLD administration; these findings could be useful in order to focus the attention on specific knowledge and/or experience gaps and plan pertinent educational programs.
A basket two-part model to analyze medical expenditure on interdependent multiple sectors

This study proposes a novel statistical methodology to analyze expenditure on multiple medical sectors using consumer data. Conventionally, medical expenditure has been analyzed by two-part models, which separately consider purchase decision and amount of expenditure. We extend the traditional two-part models by adding the step of basket analysis for dimension reduction. This new step enables us to analyze complicated interdependence between multiple sectors without an identification problem. As an empirical application for the proposed method, we analyze data of 13 medical sectors from the Medical Expenditure Panel Survey. In comparison with the results of previous studies that analyzed the multiple sector independently, our method provides more detailed implications of the impacts of individual socioeconomic status on the composition of joint purchases from multiple medical sectors; our method has a better prediction performance.
Cardiac Troponin I in Non- Acute Coronary Syndrome Patients with Chronic Kidney Disease

Objective The aim of this study was to assess the results of troponin I (cTnI) in non- acute Coronary Syndrome (ACS) patients with chronic kidney disease (CKD). We also examined the risk factors for elevated cTnI in non-ACS patients with CKD and whether stage 5 CKD modifies the associations of elevated cTnI and the risk factors in non-ACS patients with CKD. Methods A retrospective study was performed. Logistic regression models were used. Results 293 non-ACS patients with CKD were included in the current study. 43.34% non-ACS patients with CKD have an elevated cTnI level and 5.12% have an elevated cTnT level in MI range. In CKD patients without ACS and heart failure, only 26.03% (38/146) patients have an elevated cTnT level. In adjusted analyses, age, diastolic blood pressure and congestive heart failure is associated with an elevated cTnI level in non-ACS patients with CKD. Congestive heart failure is associated with an elevated cTnI level in non-ACS patients with CKD (OR 2.30, 95% CI 1.08,4.88, P=0.03). Stage 5 CKD does not modify the association of congestive heart failure and an elevated cTnI level. Conclusion 43.34% non-ACS patients with CKD and 26.03% CKD patients without ACS and congestive heart failure have an elevated cTnI level. Congestive heart failure is associated with an elevated cTnI level in non-ACS patients with CKD. Stage 5 CKD does not modify the association of congestive heart failure and an elevated cTnI level.
Postoperative Epileptic Seizures in Children: Is the Brain Incision a Risk Factor?

BACKGROUND Postoperative seizures (PSs) after neurosurgical operations are common but little is known about the role of surgical brain incision on their genesis. This topic has not been addressed so far. OBJECTIVE To verify if the corticotomy affects the risk of PSs and postoperative epilepsy (PE) in children. METHODS One hundred forty-three consecutive pediatric cases operated on for supratentorial lesions at the same institution in the last 15 yr have been retrospectively reviewed by dividing them into group A, 68 children who required brain corticotomy mainly for hemispheric tumors, and group B, 75 children treated through extracortical approaches mainly for suprasellar and optic tumors. Patients with possible "epileptic" biases, like preoperative seizures, were excluded. RESULTS No significant differences have been found between group A and B as far as incidence of PSs (11.7% vs 14.5%) and PE (4.5% vs 6.5%), timing, and type of seizures are concerned after a mean 6.8 yr follow-up. The size of corticotomy in group A (<3 cm2 vs >3 cm2) had no impact on epileptogenesis as well as the other variables considered in both groups (age, sex, extent of lesion resection). CONCLUSION This study shows that the surgical cortical "trauma" would not represent a risk factor for PSs and PE. According to the present analysis and the literature, other causes seem to be involved (namely, electrolytic imbalance and brain gliosis). This information is important for preoperative surgical planning and postoperative management. A validation by both adult series and prospective studies is needed.
Interfacial water molecules at biological membranes: Structural features and role for lateral proton diffusion

Proton transport at water/membrane interfaces plays a fundamental role for a myriad of bioenergetic processes. Here we have performed ab initio molecular dynamics simulations of proton transfer along two phosphatidylcholine bilayers. As found in previous theoretical studies, the excess proton is preferably located at the water/membrane interface. Further, our simulations indicate that it interacts not only with phosphate head groups, but also with water molecules at the interfaces. Interfacial water molecules turn out to be oriented relative to the lipid bilayers, consistently with experimental evidence. Hence, the specific water-proton interaction may help explain the proton mobility experimentally observed at the membrane interface.
Radiographic assessment of maxillary sinus lateral wall thickness in edentulous posterior maxilla

Background and aim Given the importance of evaluating the maxillary sinus lateral wall thickness (LWT) to avoid complications during surgery, the aim of this study was to examine LWT as well as the effect of residual ridge height (RH), edentulous region, type of edentulism, age and gender on it. Methods In this cross-sectional study conducted in 2016, 150 samples of the CBCT imaging archives of the Oral and Maxillofacial Radiology Clinic in Babol, Iran, were evaluated retrospectively. In the coronal section, RH and LWT (at 3, 7, 10 and 15 mm from the lowest point of the sinus floor) were measured in NNT software in millimeters. Data were analyzed using the SPSS v22 software through independent-samples t-test, paired-samples t-test and ANOVA. Results In 150 assessed images, by increasing the wall distance from the floor, the mean sinus lateral wall thickness was increased (p=0.01). There was no relationship between gender and age with the sinus lateral wall thickness (p>0.05). RH showed a significant relationship with LWT so that the higher the RH, the greater the LWT (p<0.05). It was also observed that the mean LWT was 1.31±0.3 mm in the partial edentulism and 0.95±0.26 mm in the complete edentulism (p<0.05). The maximum thickness was found in the first molar and the minimum values were in the second premolar and the second molar. Conclusion Due to the impact of residual ridge height and type of edentulism on LWT and anatomical variations observed in the maxillary sinus, CBCT assessment is recommended before surgery such as sinus lifting in this area.
Automating Stroke Patient Evaluation Using Sensor Data and SVM

Evaluation of post-stroke hemiplegic patients is an important aspect of rehabilitation, especially for assessing improvement of a patient's condition from a treatment. It is also commonly used to evaluate stroke patients during theraputic clinical trials [1]. The Fugl-Meyer Assessment is one of the most widely recognized and utilized measures of body function impairment for post-stroke patients [2]. We propose a method for automating the upper-limb portion of the Fugl-Meyer Assessment by gathering data from sensors monitoring the patient. Features are extracted from the data and processed by a Support Vector Machine (SVM). The output from the SVM returns a value that can be used to score a patient's upper limb functionality. This system will enable automatic and inexpensive stroke patient evaluation that can save up to 30 minutes per patient for a doctor, providing a huge time-saving service for doctors and stroke researchers.
The Distribution of Henipaviruses in Southeast Asia and Australasia: Is Wallace’s Line a Barrier to Nipah Virus?

Nipah virus (NiV) (Genus Henipavirus) is a recently emerged zoonotic virus that causes severe disease in humans and has been found in bats of the genus Pteropus. Whilst NiV has not been detected in Australia, evidence for NiV-infection has been found in pteropid bats in some of Australia’s closest neighbours. The aim of this study was to determine the occurrence of henipaviruses in fruit bat (Family Pteropodidae) populations to the north of Australia. In particular we tested the hypothesis that Nipah virus is restricted to west of Wallace’s Line. Fruit bats from Australia, Papua New Guinea, East Timor and Indonesia were tested for the presence of antibodies to Hendra virus (HeV) and Nipah virus, and tested for the presence of HeV, NiV or henipavirus RNA by PCR. Evidence was found for the presence of Nipah virus in both Pteropus vampyrus and Rousettus amplexicaudatus populations from East Timor. Serology and PCR also suggested the presence of a henipavirus that was neither HeV nor NiV in Pteropus alecto and Acerodon celebensis. The results demonstrate the presence of NiV in the fruit bat populations on the eastern side of Wallace’s Line and within 500 km of Australia. They indicate the presence of non-NiV, non-HeV henipaviruses in fruit bat populations of Sulawesi and Sumba and possibly in Papua New Guinea. It appears that NiV is present where P. vampyrus occurs, such as in the fruit bat populations of Timor, but where this bat species is absent other henipaviruses may be present, as on Sulawesi and Sumba. Evidence was obtained for the presence henipaviruses in the non-Pteropid species R. amplexicaudatus and in A. celebensis. The findings of this work fill some gaps in knowledge in geographical and species distribution of henipaviruses in Australasia which will contribute to planning of risk management and surveillance activities.
Scutellaria extract decreases the proportion of side population cells in a myeloma cell line by down-regulating the expression of ABCG2 protein.

BACKGROUND AND AIMS Scutellaria is one of the most popular traditional Chinese herbal remedies against various human diseases, including cancer. In this study, we examined the active effects of Scutellaria extract and its main flavonoid constituents on the proportion of side population cells within human multiple myeloma cell line RPMI8226 in vitro and explored the potential molecular mechanisms involved. MATERIALS AND METHODS The contents of flavonoids in ethanolic extract of Scutellaria baicalensis Georgi were determined using high performance liquid chromatography. The antiproliferative effect of the ethanolic extract on RPMI-8226 was determined by CCK assay. Apoptosis was measured by annexin combining with propidium iodide in a flow cytometer. Cell cycle analysis was performed by propidium iodide staining in combination with flow cytometry analysis. Hoechst 33342 exclusion assay was used for the identification of side population within RPMI8226 cells. The expression of ABCG2 protein was assessed by Western blotting assay. RESULTS The content of major flavonoids constitutents of Scutellaria extract was baicalin (10.2%), wogonoside (2.50%), baicalein (2.29%), and wogonin (0.99%), respectively. The crude Scutellaria extract did not show significant anti-proliferative effect, apoptosis induction and cell cycle arrest in RPMI-8226 within the concentrations of 1-75μg/mL. However, the ethanolic extract, baicalein, wogonin and baicalin reduced the side population cells in RPMI-8226, and data showed that baicalein and wogonin had stronger inhibitory effects. Correspondingly, they also exhibited significant effects on decreasing the expression level of ABCG2 protein in RPMI-8226 in vitro. CONCLUSIONS Our results for the first time demonstrated a novel mechanism of action for Scutellaria extract and its main active flavonoids, namely targeting SP cells by modulating the expression of ABCG2 protein. This study provides an insight for new therapeutic strategies targeting cancer stem cells of multiple myeloma.
C1-Esterase Inhibitor from Human Plasma-An Improved Process to Achieve Therapeutic Grade Purity

C1-Esterase Inhibitor (C1-INH) is a protein present in human plasma and is a member of serine protease inhibitors super family. C1-INH is a molecule with lot of therapeutic importance and is widely used in the treatment of Angioedema and in the current research an improved purification scheme is developed to fractionate C1-INH from human plasma. By a series of chromatography steps C1-INH is purified to homogeneity. A simple three step chromatography procedure has been described excluding the more inefficient or cumbersome methods like precipitation or affinity capture. The C1-INH purified by this scheme is characterized along with the reference molecule. C1-INH produced by this method is a single-chain glycoprotein with a molecular weight of 85-93 KDa with increased purity and yields of 100-120 mg/L of plasma. The chromatography steps are easily scalable and the process is economical and adaptable for therapeutic protein manufacture.
[Association between RIPK4 relative copy number and prognosis of colorectal cancer patient after oxaliplatin-based chemotherapy].

OBJECTIVE To investigate the association between receptor-interacting kinase protein 4 (RIPK4) relative copy number (RCN) and prognosis of stage III( colorectal cancer (CRC) patients treated with oxaliplatin-based chemotherapy. METHODS RIPK4 RCN was determined by real-time PCR and then dichotomized into high RIPK4 RCN group(n=35) and low RIPK4 RCN group (n=104) using the third quartile as the cut-off point. Overall survival (OS) and recurrence-free survival (RFS) were compared between high and low RIPK4 RCN groups. The subgroup prognostic analysis was also conducted based on tumor site. RESULTS The median follow-up period was 49 months (ranged 4 to 98 months). Patients with high RIPK4 RCN had poorer OS than those with low RIPK4 RCN, which reached marginal significance(median OS, 43.0 months vs. 53.5 months, P=0.074). Meanwhile there was no significant difference of RFS between two groups (P=0.352). In colon cancer subgroup, high RIPK4 RCN was significantly associated with poor OS (median OS, 31.5 months vs. 56.6 months, P=0.015) but not with RFS (P=0.135). In rectal cancer subgroup, RIPK4 RCN was not associated with both OS and RFS (P=0.981, P=0.738). Multivariate analysis revealed that high RIPK4 RCN was an independent prognostic factor of OS in stage III( CRC patients treated with oxaliplatin-based chemotherapy (HR=2.903, 95% CI: 1.275 to 6.610). CONCLUSION RIPK4 RCN is significantly associated with OS in stage III( colon cancer patients receiving oxaliplatin-based chemotherapy and may be a novel biomarker that can predict the efficacy of oxaliplatin in colon cancer patients.
The crossover conformational shift of the GTPase atlastin provides the energy driving ER fusion

The homotypic fusion of endoplasmic reticulum membranes is catalyzed by the atlastin GTPase. The mechanism involves trans-dimerization between GTPase heads and a favorable crossover conformational shift, catalyzed by GTP hydrolysis, that converts the dimer from a “prefusion” to “postfusion” state. However, whether crossover formation actually energizes fusion remains unclear, as do the sequence of events surrounding it. Here, we made mutations in atlastin to selectively destabilize the crossover conformation and used fluorescence-based kinetic assays to analyze the variants. All variants underwent dimerization and crossover concurrently, and at wild-type rates. However, certain variants were unstable once in the crossover dimer conformation, and crossover dimer stability closely paralleled lipid-mixing activity. Tethering, however, appeared to be unimpaired in all mutant variants. The results suggest that tethering and lipid mixing are catalyzed concurrently by GTP hydrolysis but that the energy requirement for lipid mixing exceeds that for tethering, and the full energy released through crossover formation is necessary for fusion.
