Growth inhibitor found in Centaurea spp.
Creators: name: Fletcher, Ronald Austin
Publisher: name: University of British Columbia
Year: 2011

description: The knapweeds were introduced into North America in the nineteenth century. They have now established themselves and are spreading rapidly. In British Columbia’s dry interior they grow in dense infestations, tending to exclude as well as out-compete other plants. Because of this characteristic they now present a serious problem. It has been suspected that toxic substances produced by the knapweeds may be partially responsible for enabling them to establish themselves at the expense of other plants. The object of this study, therefore, was to establish the presence and location of inhibitory substances in three species of knapweed: Centaurea repens, Centaurea diffusa, and Centaurea maculosa; and if possible to identify the chemical structure of the compounds responsible. In order to determine whether inhibitors might be present, tomatoes were grown in both infested and non infested soil. Also, dried leaf powder from the knapweed was added to greenhouse soil to observe the effects it might have on the growth of tomatoes. Leaf, stem, root and seed of the knapweed were extracted separately with different solvents: ether, water and ethanol. Germination tests, using lettuce, barley and cress as test crops, were used as methods of bioassay. In order to isolate the inhibitory compound, ascending paper chromatography was employed using the aqueous phase of n-Butanol:acetic acid:water (4:1:5) as the solvent. The inhibitor was located on the chromatographic paper by means of germination tests. Chromogenic sprays and comparisons of Rf values with different solvents were made in order to identify the inhibitor. To further characterize the compound an ultraviolet spectrum was carried out. The findings of the soil studies indicated that knapweed infested soil, and soil containing leaf powder of knapweed, were inhibitory to the growth of tomatoes. The inhibitor was found to be present in all the three species studied, and was located mainly in the leaves. It proved to be both ether and water soluble, and non-specific, being inhibitory to all the crops tested. The inhibitor was found as a pale yellow fluorescent band at an Rf of 0.9. Chromogenic sprays indicated the inhibitor to be an indole derivative. This was confirmed by the ultraviolet absorption spectrum.

description: Abstract

This study focuses on the employment status of women in the Cuddalore district is the main emphasis of this study, particularly the effects of work and education on women. The findings showed a strong positive correlation between women's empowerment in decision-making, control over resources, and voice, and employment and education.  Women who have an education are more likely to be employed, and as employment builds economic strength and financial independence, it also contributes to their empowerment. Higher education is a key component of the Millennium Development Goals since it not only increases human potential but also establishes the foundation for a high standard of living. The information highlights how crucial it is to take regional differences into account when developing financial policies and assistance initiatives. Regarding this study, the questionnaire's reliability was 90%. Both descriptive and inferential statistical methods, including the chi- square test, were applied to the data analysis. The results showed that women with higher education degrees had greater career opportunities. It was also discovered that women's employment and advancement in the workforce are significantly influenced by higher education.

description: We simulate CMB maps including non-Gaussianity arising from cubic order perturbations of the primordial gravitational potential, characterized by the non-linearity parameter $g_{NL}$. The maps are used to study the characteristic nature of the resulting non-Gaussian temperature fluctuations. We measure the genus and investigate how it deviates from Gaussian shape as a function of $g_{NL}$ and smoothing scale. We find that the deviation of the non-Gaussian genus curve from the Gaussian one has an antisymmetric, sine function like shape, implying more hot and more cold spots for $g_{NL}>0$ and less of both for $g_{NL}<0$. The deviation increases linearly with $g_{NL}$ and also exhibits mild increase as the smoothing scale increases. We further study other statistics derived from the genus, namely, the number of hot spots, the number of cold spots, combined number of hot and cold spots and the slope of the genus curve at mean temperature fluctuation. We find that these observables carry signatures of $g_{NL}$ that are clearly distinct from the quadratic order perturbations, encoded in the parameter $f_{NL}$. Hence they can be very useful tools for distinguishing not only between non-Gaussian temperature fluctuations and Gaussian ones but also between $g_{NL}$ and $f_{NL}$ type non-Gaussianities.

description: Background: Balance is one of the primary abilities developed during the motor and skeletal evolution. Regular and specific training throughout life-span could improve the balance and, in turn the execution of complex motor patterns as well as of the normal daily activities (Ricotti, 2011). Aim: In this study we investigate the relation between the balance abilities and different types of physical activities (PA) in youths. Method: Thirty-six subjects (age: 24±17 years; male/female:18/18) were enrolled and grouped into two PA categories: the exergame group includes subjects who use Nintendo Wii Balance Board gaming at least twice a week (n=12), and the sport group includes subjects who practice sport at least twice a week (n=12). Subjects who do not practice sports or physical activity were enrolled as control (n=12). The postural control was assessed by means of normal standing balance tests (for 30s) with open eyes (OE) and closed eyes (CE), respectively; a force plate (AMTI Model OR6-7) was used to acquire data of the centre of pressure (CoP) sway. According to previous study [2], we were able to select two variables from CoP sway: the total displacement of sway (DOT) and the mean velocity. The mean velocity was estimated for anteroposterior (MVAP) and lateral-lateral (MVLL) directions, respectively. Statistical analysis was carried out with SPSS (SPSS Inc, Ver. 20). Significance of differences was assessed by one-way ANOVA followed by Bonferroni post-hoc test (95% confidence level). Result: ANOVA revealed significant differences among groups for the three variables. We found that the mean of DOT and MVAP was significantly decreased in the exergame’s group compared with the others study groups. Of note, the differences were higher for CE than OE test. Conclusion: Our findings suggest that the balance ability reaches a mastery level during the youth age-period. However, a specific program of balance training using the exergaming approach could improve the proficiency level of the aforementioned ability more than conventional sport training.

description: In karate, balance control represents a key performance determinant (1). Balance stability was reported to be related to a refined control of the center of mass (CoM) displacement (2). The aim of the current study was to quantitatively investigate the motor strategies adopted by elite and non-elite karateka to maintain balance control. We analyzed the execution of traditional karate techniques (kata) in two groups: elite Masters (n=6, 31±19 years) and non-elite Practitioners (n=4, 25±9 years). On each participant, the three-dimensional coordinates of 14 reflective markers (landmarks: right and left tragion, acromion, olecranum, radius styloid process, great trochanter, femur lateral epicondyle, lateral malleolus) were recorded by nine infrared cameras of an optoelectronic motion analyzer with a 120 Hz sampling rate. Kinematic parameters assessed were: CoM, step width, joints range of motions. CoM kinematics was computed according to the segmental centroid method (3). In the 11 steps of kata, CoM height was 8% lower (p<0.05, Mann-Whitney non parametric U-test), CoM average velocity and rms acceleration were approximately 35% higher (p<0.05) and step width was higher (p<0.05) in Masters. There was a significant difference between groups in CoM height and step width in seven and six out of the 11 steps, respectively. CoM vertical displacements resulted almost equal along the vertical direction, while in the horizontal direction it was significantly (p<0.05) higher in Masters than in Practitioners. Results suggest that elite karateka developed a refined body balance control, obtained through the increase of the base of support and different maneuvers of lower limbs. The proposed method could be used to objectively detect talented karateka, to measure proficiency level and to assess training effectiveness.

description: We discuss the representations that new scalar degrees of freedom (beyond those in the minimal standard model) can have if they couple to quarks in a way that is consistent with minimal flavor violation. If the new scalars are singlets under the flavor group then they must be color singlets or color octets. In this paper we discuss the allowed representations and renormalizable couplings when the new scalars also transform under the flavor group. We find that color \bar{3} and 6 representations are also allowed. We focus on the cases where the new scalars can have renormalizable Yukawa couplings to the quarks without factors of the quark Yukawa matrices. The renormalizable couplings in the models we introduce automatically conserve baryon number.

description: In the absence of an external field, the Rashba spin-orbit interaction (SOI) in a two-dimensional electron gas in a semiconductor quantum well arises entirely from the screened electrostatic potential of ionized donors. We adjust the wave functions of a quantum well so that electrons occupying the first (lowest) subband conserve their spin projection along the growth axis (Sz), while the electrons occupying the second subband precess due to Rashba SOI. Such a specially designed quantum well may be used as a spin relaxation trigger: electrons conserve Sz when the applied voltage (or current) is lower than a certain threshold V*; higher voltage switches on the Dyakonov-Perel spin relaxation.

Early Outcomes after Carotid Endarterectomy and Carotid Artery Stenting for Carotid Stenosis in the ACS-NSQIP Database
Creators: name: Zeenat Qureshi Stroke Institutes
Publisher: name: Zenodo
Year: 2023

description: Background

Carotid endarterectomy (CEA) and carotid artery stenting (CAS) are both viable treatment options for carotid artery stenosis. We sought to compare perioperative outcomes after CEA and CAS for the management of carotid stenosis using a “real-world” sample.

Methods

We conducted a retrospective observational study using the National Surgical Quality Improvement Program database to compare 30-day (periprocedural) outcomes in patients with carotid stenosis undergoing CEA versus CAS from 2005 to 2012. Baseline characteristics and periprocedural outcomes including stroke, myocardial infarction, mortality and combined outcome (composite of any stroke, myocardial infarction, or death) were compared.

Results

A total of 54,640 patients were identified who underwent CEA and 488 who underwent CAS. Patients undergoing CEA were more likely to be older and have symptomatic stenosis, and less likely to be white, have congestive heart failure, and have chronic obstructive pulmonary disease. There were no significant differences between CEA and CAS in periprocedural mortality (0.9% vs. 1.2%, p = 0.33), stroke (1.6% vs. 1.6 p = 0.93), myocardial infarction (0.9% vs. 1.6%, p = 0.08), or combined outcome (3.0% vs. 4.9%, p = 0.09). The interaction between symptomatic status and procedure type was not significant, indicating the association of symptomatic status with 30-day mortality (p = 0.29) or the combined periprocedural outcome (p = 0.57) were similar in cases receiving CEA and CAS.

Conclusion

Early outcomes after CEA and CAS for carotid artery stenosis appear to be similar in a “real-world” sample and comparable to clinical trials. Patients undergoing CAS were more likely to be younger and surgically have higher risk based on baseline characteristics likely reflecting clinical practice case selection.

description: We report the observation of wave turbulence on the surface of a ferrofluid mechanically forced and submitted to a static normal magnetic field. We show that magnetic surface waves arise only above a critical field. The power spectrum of their amplitudes displays a frequency-power law leading to the observation of a magnetic wave turbulence regime which is experimentally shown to involve a 4-wave interaction process. The existence of the regimes of gravity, magnetic and capillary wave turbulence is reported in the phase space parameters as well as a triple point of coexistence of these three regimes. Most of these features are understood using dimensional analysis or the dispersion relation of the ferrohydrodynamics surface waves.

Subjects: subject: Radiochemotherapy
subject: locally advanced cervical cancer
subject: external radiation and interstitial brachytherapy
subject: quality of life

description: Objectives: To evaluate clinical results and long-term patient reported outcome measures (PROM) on quality of life in cervical cancer patients following radiochemotherapy (RCT) and brachytherapy (BT) as definitive treatment. Materials and methods: Between 2003 and 2023, a total of 132 patients with advanced cervical cancer were evaluated for possible treatment. Patients treated by postoperative RCT, palliative radiotherapy, and those treated for recurrent disease were excluded. Thus, 46 patients receiving standard RCT and BT as their curative treatment and were included in this study. PROMs were assessed prospectively by the patients’ self-completion of the EORTC-QLQ-C30 and EORTC-QLQ-CX24. Results: Five-year overall survival (OS), distant metastases-free survival (DMFS), and pelvic-tumor-free survival rates (PTFS) were 53%, 54% and 83%, respectively. A significant impact on OS was seen for FIGO-stage (IIB-IIIA: 79% vs IIIB-IVA: 33%, p=0.015), for overall treatment time (OTT) (50-65d: 64% vs >65d: 38%, p=0.004), and for Rectal D2cc (≤73 Gy: 50% vs. >73Gy: 38%, p=0.046). The identical parameters were significantly associated with DMFS (FIGO-stage: p=0.012, OTT: p=0.008, D2cc: p=0.024). No parameters of significant influence on PTFS were seen. On multivariate analysis, an impact of FIGO-stage on OS (p=0.05) and DMFS (p=0.014) was detected, and of Rectal D2cc on DMFS (p=0.031). Overall QoL-score of 63/100. Cognitive function was the least impaired (84/100), while role functioning was the worst (67/100). On the symptom scale, Insomnia (46/100), Fatigue (41/100), Dyspnea (32/100), Pain (26/100) and financial difficulties (25/100) were scored the worst. According to the EORTC-QLQ-CX24 questionnaire, peripheral neuropathy (36/100) and lymphedema (32/100) occurred most frequently. Impaired sexual/vaginal functioning (32/100) and body image (22/100) were also frequently recorded. Conclusion: In patients with advanced cervical carcinoma a combination of RCT and BT remains an excellent treatment option. In terms of patient reported long-term quality of life specific support is needed to alleviate symptoms including lymphedema, peripheral neuropathy, and impaired sexual activity.

description: In dieser Arbeit wurden verschiedene Aspekte der chemischen Wasserstoffspeicherung und der Verstromung von Wasserstoff in Brennstoffzellen behandelt. Den Kern der Arbeit bildeten Versuche in Polymerelektrolytmembran-Brennstoffzellen, sowohl bei niedrigen Temperaturen (60-100°C), als auch bei erhöhten Temperaturen (160-200°C). Das Ziel der Arbeit war es, die Speicherung und Freisetzung von Wasserstoff in und aus organischen Molekülen (LOHC) mit der direkten Verstromung in Brennstoffzellen zu kombinieren. Dabei wurden Brennstoffe und LOHC-Speichermoleküle direkt in der Brennstoffzelle eingesetzt – Direkt-Brennstoffzelle. Zu diesen LOHC-Molekülen zählten 2-Propanol, 1-Cyclohexylethanol, Diisopropylether, Propen und Perhydrobenzyltoluol. Neben der Untersuchung von verschiedenen Brennstoffen wurde der Einfluss diverser Prozess- und Materialparameter der Membranelektrodeneinheit auf das Leistungsvermögen von Wasserstoff-Brennstoffzellen und Direkt-Brennstoffzellen bestimmt.
description: In this work, various aspects of chemical hydrogen storage and the conversion of hydrogen to electricity in fuel cells were investigated. Most experiments were conducted in polymer electrolyte membrane fuel cells, both at low temperatures (60-100°C), and at elevated temperatures (160-200°C). The goal of the work was to combine the storage and release of hydrogen in organic molecules (LOHC) with direct conversion to electricity in fuel cells. This involved the use of LOHC storage molecules directly in the fuel cell – Direct LOHC Fuel Cell. These LOHC molecules included 2-propanol, 1-cyclohexylethanol, diisopropyl ether, propene and perhydro benzyl toluene. In addition to investigating different fuels, the influence of various process and material parameters of the membrane electrode assembly on the performance of hydrogen fuel cells and Direct LOHC Fuel Cells was determined.

description: Orienteering races usually develop in wooded lands with large differences in slopes. In addition to the climbs, long descents are frequently covered. Therefore, lower limb muscular strength is necessary to sustain these challenges on rough terrains (1). Eight male orienteers of junior Italian team (OR; age, 19±1.6yr), 8 cross country track and fields experienced runners (TF; 20±4.5yr), and 8 sedentary persons (control group CG; 23±2.7yr), all with right lower limb dominance volunteered. Between groups, no age-, weight-, height-, and BMI-related differences were found (ANOVA, p>0.05). Each participant performed and an isokinetic dynamometer measured 5 repetitions of right and left knee flexion and extension at the angular speeds of 60-120-180-240-300deg/sec respectively. The ratios of peak torques between knee flexors and extensors were also computed, at each angular speed. Descriptive statistics were calculated within subject, group, movement, angular speed, and side. For each movement, the effects of group and side, and group×side interactions on peak torques at different speeds were compared by ANOVA (statistical significance 5%). On average within group, flexor and extensor muscles of the right knee were stronger than those of contralateral limb, but no significant differences were found. Side-related differences were similar in all groups (p>0.05). In both sides and movements at each angular speed, OR performed larger peak torques than TF and CG (p<0.001). For each angular velocity, the ratios between flexors and extensors were larger in OR (p<0.001). For orienteers, overcoming natural obstacles, and engaging eccentric work of knee muscles when running downhill could represent effective training tools. Data could be of interest for athletes, coaches, physical therapists, and physicians to set efficient training plans, to prevent trauma, and to define rehabilitation treatments. Further investigations should be extended to other muscular districts, and to other sports.

An investigation of the penetration of thin aluminum oxide films by liquid bismuth
Creators: name: Allday, William John
Publisher: name: University of British Columbia
Year: 2011

description: The penetration of thin aluminum oxide films by liquid bismuth was studied between 350 and 500°C. A correlation was sought between the type and thickness of the oxide film, and the time and nature of the attack. Mechanical and electropolished, and anodized films of different thicknesses were exposed to liquid bismuth either by immersing a plate in the liquid and measuring the contact angle or by melting a drop of bismuth on a specific area of a plate. Electropolished surfaces had no resistance to attack by the bismuth. Pitting and edge attack occurred with all other surface preparations. The anodized films often separated from the aluminum under thermal stresses and allowed the bismuth to spread under the film, sometimes removing it entirely. Attempts were made to control the number and nature of defects in the oxide film, but the difficulty of this is shown by the scatter in the results. No attack on aluminum oxide itself is likely and no diffusion of bismuth through the oxide was found at the temperatures used. The conclusion was reached that the bismuth penetrated the oxide film only at points where there was a high concentration in the film of some impurity oxide (such as nickel or copper oxides) that reacts with bismuth.

description: We have recently carried out the first wide-field hydrogen Paschen-alpha line imaging survey of the Galactic Center (GC), using the NICMOS instrument aboard the Hubble Space Telescope. The survey maps out a region of 2253 pc^2 around the central supermassive black hole (Sgr A*) in the 1.87 and 1.90 Micron narrow bands with a spatial resolution of 0.01 pc at a distance of 8 kpc. Here we present an overview of the observations, data reduction, preliminary results, and potential scientific implications, as well as a description of the rationale and design of the survey. We have produced mosaic maps of the Paschen-alpha line and continuum emission, giving an unprecedentedly high resolution and high sensitivity panoramic view of stars and photo-ionized gas in the nuclear environment of the Galaxy. We detect a significant number of previously undetected stars with Paschen-alpha in emission. They are most likely massive stars with strong winds, as confirmed by our initial follow-up spectroscopic observations. About half of the newly detected massive stars are found outside the known clusters (Arches, Quintuplet, and Central). Many previously known diffuse thermal features are now resolved into arrays of intriguingly fine linear filaments indicating a profound role of magnetic fields in sculpting the gas. The bright spiral-like Paschen-alpha emission around Sgr A* is seen to be well confined within the known dusty torus. In the directions roughly perpendicular to it, we further detect faint, diffuse Paschen-alpha emission features, which, like earlier radio images, suggest an outflow from the structure. In addition, we detect various compact Paschen-alpha nebulae, probably tracing the accretion and/or ejection of stars at various evolutionary stages.

description: The pancreas is a glandular organ endowed with two main functions; an exocrine function that assists digestion and an endocrine function that modulates blood glucose concentration. Pancreatic Beta-cells produce insulin to regulate/lower blood glucose concentration, driving them into cells to be utilized. Distortions of the architecture of pancreatic Beta-cells lead to function loss; thus, preservation/restoration of their cytoarchitecture would sustain their functions. Vernonia amygdalina is a vital plant acknowledged widely for its antioxidant and anti-diabetic effects; however, its impact on the pancreas has received little attention. This study is premeditated to examine the effects of the methanolic leaf extracts of Vernonia amygdalina (MLEVA) on the cytoarchitecture of the pancreas in Alloxan-induced pancreatic toxicity. Thirty (30) adult male Wistar rats were grouped into 6 (A-F) (n=5). Group A, the control group, received feed and water only. Group B received a single intra-peritoneal injection of 150mg/kg of Alloxan. Groups C, D, and E received single intra-peritoneal injections of 150mg/kg of Alloxan and were then treated with 200, 300, and 400 mg/kg/day of the MLEVA, respectively. Group F received a single intra-peritoneal injection of 150mg/kg of Alloxan and was orally treated with 100mg/kg/day of Vitamin E. The experiment lasted 16 days before sacrificing the animals via a median incision on the abdominal cavity, under ketamine (100mg/ml), as anaesthesia, 24 hours after their last treatment. The pancreas was carefully and rapidly processed for routine H & E staining. This study recorded a 28% mortality rate after Alloxan administration, leading to degenerative histo-pathological changes in the pancreas' endocrine and exocrine compartments. 300mg/kg of MLEVA demonstrated a marked regenerative effect on the pancreas. The MLEVA is a promising agent for managing Diabetes, evidenced by its protective and therapeutic effect on Alloxan-induced pancreatic toxicity.
