Review on the formation and growth of cerebral aneurysms

A cerebral aneurysm is a vascular condition characterized by local ballooning of an artery in the brain. Although aneurysm formation and growth are thought to be the result of destruction of the blood vessel wall, the details of the etiology are unclear. We review the formation and growth of cerebral aneurysms as follows. In the first part, we summarize the history of theories on the pathogenesis of cerebral aneurysm in chronological order from epidemiological and pathological viewpoints and based on data obtained from animal models of experimentally induced cerebral aneurysms, with a focus on the involvement of hemodynamic stress on the arterial wall. In the second part, we review computational fluid dynamics (CFD) studies on the initiation of cerebral aneurysms with a brief overview of the history of CFD in hemodynamics analysis. Of the hypotheses presented, strong emphasis is placed on that of high wall shear stress and a high wall shear stress gradient. Other leading hypotheses involving hemodynamics-related parameters are also reviewed. In the third part, we review CFD studies on the growth of cerebral aneurysms, in which hemodynamic parameters were compared between growing and stable aneurysms, to highlight the hemodynamic characteristics associated with their growth.

This review focuses on general information regarding coronavirus, pathological findings from biopsy sample of a previously published case and the standard preventive recommendations prescribed by various researchers and health authorities.
Wound healing activity of Dodonaea viscosa leaves

Effects of topical and oral administration of ethanol extract of Dodonaea viscosa was assessed on different parameters of wound healing such as wound contraction (applied as ointment), breaking strength of skin and granuloma (administered as suspension) in rats. The efficacy of the extract in dexamethasone treated animals was also evaluated. The extract was able to overcome the antihealing property of dexamethasone. In the excision model, 10 % extract treated wounds were found to have faster rate of wound contraction and epithelization. Further, The extract facilitated the healing process, evidenced by increase in the breaking strength of the incision and dead space wounds. Both the suspension and ointment of ethanol extract produced a significant response in all wound models studied.
Evaluation of Pound concept in determination of mediolateral mandibular posterior teeth position

Background: The ideal teeth arrangement is an important step for success in complete denture fabrication. There are different methods for determining the posterior denture teeth location. The purpose of this study was the comparison of posterior mandibular teeth location in the study group with Pound or Misch theory. Material and methods: An alginate mandibular impression of 80 dentate patients was taken and poured with dental stone. Retromolar pad area, mesial of canine and the lingual cusps of each posterior tooth marked on the cast and then transferred to the graded paper. Distance of each lingual cusp from the internal line of Pound triangle was measured. Data were analyzed with SPSS version 16.0. Result: In the study group, the average distance of lingual mandibular cusp from the internal line of Pound triangle was 1.69 mm in first premolars, 0.94 mm in second premolars, 0.7 mm in first molars and 0.75 mm in second molars. Conclusion: In most cases, distance of lingual mandibular cusps was within 1 mm of Pound triangle. Results were more similar to the Pound rather than the Misch theory.

Ideal harvesting point of ‘Limeira-IAC382’ trifoliate orange fruits for seed extraction

Abstract Trifoliate orange is one of the rootstocks most used worldwide mainly because it provides excellent quality fruit production. Harvest at the correct time is among factors that determine the physiological quality of seeds. The aim of this study was to identify physicochemical changes in ‘Limeira-IAC382’ trifoliate orange fruits, searching for the ideal harvest moment to obtain high quality seeds. Fruits were harvested at 180, 210 and 240 days after anthesis, stored in cold chamber and evaluated at 0, 15, 30 and 45 days of storage. The following variables were determined: mass loss, fruit color index, soluble solids, total titratable acidity and fruit juice ratio. Seeds were manually extracted and dried until reaching 30% water content. Seeds were used for the performance of germination, electrical conductivity and greenhouse seedling emergence tests. Seeds from fruits harvested at 240 DAA showed higher germination and greenhouse seedling emergence percentage compared to the other treatments until 30 and 45 days of storage in cold chamber, respectively. Storage for 45 days in cold chamber of fruits harvested at 210 DAA increases seed germination rate and the percentage of seedlings from seeds harvested at 180 DAA. It could be concluded that the harvesting of ‘Limeira-IAC382’ trifoliate orange fruits should be performed when fruits reached yellowish peel and low juice ratio, aiming at obtaining seeds with physiological quality.
A Comprehensive Comparison Between Design for Testability Techniques for Total Dose Testing of Flash-Based FPGAs

A comprehensive comparison between different design for testability (DFT) techniques for total-ionizing-dose (TID) testing of flash-based field-programmable gate arrays (FPGAs) is made to help designers choose the best suitable DFT technique depending on their application. The comparison includes muxed D scan, clocked scan, and enhanced scan DFT techniques. The comparison is done using ISCAS’89 benchmarks circuits. Points of comparisons include FPGA resources utilization, difficulty in design bring-up, added delay by DFT logic, and robust testable paths in each technique. We verified the results of each technique experimentally using Microsemi ProASIC3 FPGA’s and Cobalt 60 facility. The experimental results show a close total-dose failure level for all techniques when using worst-case test vectors (WCTVs) in total-dose testing of FPGA devices.
Outcomes of Transition to Adult HV Care in Perinatally HIV-infected Young Adults

Objective: To describe mortality in perinatally HIV-infected young adults after transition to adult care and identify associated factors. Methods: Patients who had transitioned from a pediatric outpatient clinic to adult HIV care between January 2003 and September 2012 were recruited for a retrospective cohort study, completed on April 30, 2014. The main study outcome was post-transition death. The most recent clinical and social-demographic data before transition were abstracted from medical and social records. Results: Of 51 transitioned patients, nine (18%) had died, all of HIV-related causes, most (5 [56%]) in the first year post-transition. Of 42 survivors, 33 were eligible; 27 (82%) provided consent. Immunosuppression (CD4+ T-lymphocyte [CD4] count <100 cells per μL) at transition was associated with a six-fold higher risk of mortality (67% vs. 11% in patients with CD4 count >100 cells perμL; relative risk [RR] =6.0, 95% CI=1.8819.19 [P=.005]). When controlled for CD4 count, employment at time of transition was associated with an almost 80% reduction in mortality risk (MH adjusted RR= 0.19; 95%
Deep structure of the Hellenic lithosphere from teleseismic Rayleigh-wave tomography

This research provides new constraints on the intermediate depth upper-mantle structure of the Hellenic lithosphere using a three-step Rayleigh-wave tomography. Broadband waveforms of about 1000 teleseismic events, recorded by ∼200 permanent broad-band stations between 2010 and 2018 were acquired and processed. Through a multichannel cross-correlation technique, the fundamental mode Rayleigh-wave phase-velocity dispersion curves in the period range 30–90 s were derived. The phase-velocities were inverted and a 3-D shear velocity model was obtained down to the depth of 140 km. The applied method has provided 3-D constraints on large-scale characteristics of the lithosphere and the upper mantle of the Hellenic region. Highlighted resolved features include the continental and oceanic subducting slabs in the region, the result of convergence between Adria and Africa plates with the Aegean. The boundary between the oceanic and continental subduction is suggested to exist along a trench-perpendicular line that connects NW Peloponnese with N. Euboea, bridging the Hellenic Trench with the North Aegean Trough. No clear evidence for trench-perpendicular vertical slab tearing was resolved along the western part of Hellenic Subduction Zone; however, subcrustal seismicity observed along the inferred continental–oceanic subduction boundary indicates that such an implication should not be excluded. The 3-D shear velocity model supports an N–S vertical slab tear beneath SW Anatolia that justifies deepening, increase of dip and change of dip direction of the Wadati-Benioff Zone. Low velocities found at depths <50 km beneath the island and the backarc, interrelated with recent/remnant volcanism in the Aegean and W. Anatolia, are explained by convection from a shallow asthenosphere.
Sustainable Gastronomy; power and energy use in food - is it possible to fight climate change through cookery?

This paper explores and establishes the concept of how power (energy) is used and embodied in food and cookery. It then examines how different types of cookery methods use different amounts of power, and thus cooking the same food using different methods can have different environmental impacts. It then investigates the history of “sustainable cookery”, performing a comprehensive review of historic cookbooks to highlight 23 key texts. These range from Frances Moore Lappe’s “Diet for a Small Planet” (1971), through to contemporary texts such as Diana Henry’s “Plenty: good, uncomplicated food for the sustainable kitchen” (2010), or the 4 books of the American Academy in Rome’s Sustainable Food Project (2011). These texts will be used to examine how concepts of sustainability have evolved over time.
Group-Based Skyline for Pareto Optimal Groups

Skyline computation, aiming at identifying a set of skyline points that are not dominated by any other point, is particularly useful for multi-criteria data analysis and decision making. Traditional skyline computation, however, is inadequate to answer queries that need to analyze not only <italic>individual</italic> points but also <italic>groups</italic> of points. To address this gap, we generalize the original skyline definition to the novel group-based skyline (G-Skyline), which represents Pareto optimal groups that are not dominated by other groups. In order to compute G-Skyline groups consisting of <inline-formula><tex-math notation="LaTeX">$s$</tex-math><alternatives><mml:math><mml:mi>s</mml:mi></mml:math><inline-graphic xlink:href="liu-ieq1-2960347.gif"/></alternatives></inline-formula> points efficiently, we present a novel structure that represents the points in a directed skyline graph and captures the dominance relationships among the points based on the first <inline-formula><tex-math notation="LaTeX">$s$</tex-math><alternatives><mml:math><mml:mi>s</mml:mi></mml:math><inline-graphic xlink:href="liu-ieq2-2960347.gif"/></alternatives></inline-formula> skyline layers. We propose efficient algorithms to compute the first <inline-formula><tex-math notation="LaTeX">$s$</tex-math><alternatives><mml:math><mml:mi>s</mml:mi></mml:math><inline-graphic xlink:href="liu-ieq3-2960347.gif"/></alternatives></inline-formula> skyline layers. We then present two heuristic algorithms to efficiently compute the G-Skyline groups: the point-wise algorithm and the unit group-wise algorithm, using various pruning strategies. We observe that the number of G-Skyline groups of a dataset can be significantly large, we further propose the top-<inline-formula><tex-math notation="LaTeX">$k$</tex-math><alternatives><mml:math><mml:mi>k</mml:mi></mml:math><inline-graphic xlink:href="liu-ieq4-2960347.gif"/></alternatives></inline-formula> representative G-Skyline groups based on the number of dominated points and the number of dominated groups and present efficient algorithms for computing them. The experimental results on the real NBA dataset and the synthetic datasets show that G-Skyline is interesting and useful, and our algorithms are efficient and scalable.
A correlative study of salivary and plasma glucose levels in type 2 diabetic patients with and without complications

Introduction: There are contradictory reports on using salivary glucose in diagnosis of diabetes mellitus. This study has made an attempt to estimate the salivary glucose levels in diabetic patients with and without complications and correlate them with plasma glucose as a marker of type 2 diabetes mellitus. Method: This was a Cross sectional observational study. Thirty eight type 2 diabetic patients without complications and thirty eight type 2 diabetic patients with either microvascular or macrovascular complications were the subjects of this study. Age and sex-matched normal healthy individuals were included as controls. Plasma and salivary glucose levels were estimated by spectrophotometric method. Results: We observed significantly higher glucose levels in plasma and saliva, in diabetic patients with complications, in comparison to those without complications, and normal healthy controls. There was significant positive correlation between salivary glucose and plasma glucose among all the subjects of the study. Non-linear regression analysis shows exponential relationship between plasma and salivary glucose. Conclusion: Salivary glucose analysis offers noninvasive, sensitive method for assessment of severity of diabetic complications with suitability for repeated sampling. Further studies with larger sample size need to be taken up to establish salivary glucose as a marker of diabetes mellitus.
Anti-Müllerian hormone, antral follicle count and follicle-stimulating hormone for predicting the number of oocytes retrieved in IVF/ICSI cycles

Objective To evaluate the efficacy of anti-Mullerian hormone (AMH), antral follicle count (AFC) and follicle-stimulating hormone (FSH) for predicting the number of oocytes retrieved in in-vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles. Methods In this retrospective study, a total of 122 infertile women were divided into two groups: group A, Results Group B had higher FSH levels compared with group A (8.2±3.5 IU/L vs 6.8±2.4 IU/L, P 0.05). The level of AMH was more strongly correlated with the number of oocytes retrieved than that of AFC or FSH level. The strengths of the correlation degrees were AMH level, AFC, and FSH level in turn (r=0.600, 0.511, −0.369). Conclusion AMH would be a useful predictor for ovarian response.
Experimental Reduction Of Fe-Oxyhydroxides In Simulated Carbonate and Sulfide/Sulfate Brine: Implications for Paleolake Deposits.

Mineral reduction simulations imitating various geochemical environments were conducted over 1 – 30 hours. Ferrihydrite was prepared from solid phases using a solvent-deficient method. In each experiment, ferrihydrite was abiotically reduced with sodium dithionite solution in 1 Molar buffered Na-carbonate and Na-sulfate/sulfide brine at 70°C under nitrogen atmosphere. Six (n=6) and ten (n=10) samples of resultant sulfate/sulfide and carbonate precipitates were collected, respectively. X-Ray Diffractometry (XRD) and Scanning Electron Microscopy (SEM) analytical methods were used to characterize the experimental products. Diagenetic siderite and goethite in carbonate simulations were identified with XRD. Siderite was observed as spherules and platy structures possibly of chukanovite. Calculations using PHREEQ software predicted siderite and pyrite forming in carbonate and sulfate/sulfide brines respectively. The expected pyrite did not precipitate. Rather magnetite, which was unexpected, was formed by either partial reduction of ferrihydrite or partial oxidation of an intermediate reduced phase such as wüstite. Understanding the diagenetic pathways and water-mineral interactions of these systems is necessary for paleoenvironmental reconstruction and for the fidelity of paleomagnetic records.

Isolation and Characterization of Bacteriophages against Escherichia coli Isolates from Chicken Farms

| The present study was conducted aiming to isolate and characterize bacteriophages with lytic activity against Escherichia coli infected poultry. A total of 72 samples of soil from 18 chicken farms were collected in six provinces in the Mekong Delta, Vietnam. Samples were primarily subjected to rapid detection methods, and then isolation of phage was done by a double agar layer method using E. coli as the host system. Phages were characterized on the basis of plaque morphology, pH susceptibility and host range. Results showed that the recovery of phages in soil was at a high proportion (73.6%), in which the percentage of phage isolates was higher from Noi chicken farms (66.6%) as compared to broiler chicken farms (58.3%). Four different phage morphotypes were observed against E. coli. There was a high rate of phages which existed at pH 2.0 at 26.4%. The percentage of phages that could survive from pH 5.0 to pH 3.0 significantly decreased from 84.9% to 39.6%. TEM analysis performed for MHH6 and PR2 which had widest host range, revealed that both phages belong to the Myoviridae family. It could be concluded that the MHH6 and PR2 phages have a wide host range and thus exhibit the potential to be used as a drug substitute tool against E. coli infection in chickens.
Age-Related Changes in two Muscle Enzymes of the Hawk Moth

AGE -RELATED CHANGES IN TWO MUSCLE ENZYMES OF THE HAWK MOTH, MANDUCA SEXTA Connor McMahon Director: Bernie Wone, Ph.D. Aging has been associated with significant declines in muscle strength and mass. The specific molecular mechanisms behind these changes, however, are not well known. One potential mechanism behind muscle aging could be enzymatic dysfunction. This research examines the enzyme changes that occur in the dorsolateral flight muscles of the hawk moth. The hawk moth, Manduca sexta, is an excellent model of muscle aging due to its short lifespan, ease of rearing, and endothermic flight muscles. We assayed citrate synthase (CS) and β-hydroxyacyl-CoA dehydrogenase (HADH) to determine the activity of the tricarboxylic acid cycle and fatty acid oxidation, respectively. A significant change in HADH activity was observed in male hawk moths between daytime and nighttime, but this change was not detected in females. Significant changes in CS activity occurred between middle aged and aged female hawk moths. Overall, CS activity increased with age for females, and aged females showed less distinction between daytime and nighttime CS activity. Increases in CS activity suggest age-related TCA cycle dysfunction in female hawk moths. This research identifies how beta oxidation and TCA activity change differently for male and female hawk moths via aging.
Mercury in natural health products as a cause of membranous nephropathy

Abstract Membranous nephropathy is a glomerular disease characterized by diffuse subepithelial immune complex deposition along the glomerular basement membrane. It can be both primary and secondary to malignancy and various drugs. An emerging area of concern is heavy metal exposure from use of largely unregulated natural health products. Here we present a case of biopsy-proven membranous nephropathy due to natural health products contaminated with mercury.
