PVP/Clay/Vanadium Oxide Nanocomposites Development and Characterization for Potential Use as Controlled Drug Release Matrix in Diabetes’ Treatment

Research in drug release field, nowadays, focuses on more efficient systems for better release of the drug and wider timespan of action, granting several benefits to the patient’s organism and to the industry. The present work aims on developing a matrix of polymer nanocomposite based on Polyvinylpyrrolidone (PVP), bentonite clay and two different vanadium oxides, via spray drying technique. The goal is to achieve a long and steady release of metformin hydrochloride in future formulations with this drug. Since either the nanocomposites or metformin hydrochloride is highly hydrophilic, it is most suited for a future formulation of tablets. For now, the nanocomposites obtained were characterized through Nuclear Magnetic Resonance (NMR), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), Thermogravimetric Analysis (TGA) and Fourier Transform Infrared Spectroscopy (FTIR). The SEM and XRD analysis portrayed a very amorphous and homogenized material. TGA and FTIR proved the insertion of the nanoparticles, thus granting to the new material a slightly higher thermal resistance. The NMR analysis, using T1H parameters, is key for determining the formulations would behave better for extending the resistance of the nanocomposite’s matrix with the drug in later dissolution of tablets.
Attrition from Child/Youth Mental Health Treatment: The Role of Child Symptoms

This study examined the associations between social adversity, barriers-to-care (logistical obstacles, wait-time) and participation in children’s mental health treatment. The theoretical role of child symptoms (impact on the child, family burden) was addressed. Records were obtained for 1,963 parents who had accessed community-based care for their child (3-17 years). Data were collected as part of a provincial (Ontario, Canada) screening and outcome measurement initiative. The data were analyzed using multivariate logistic regression. Children with behavioural problems were at increased risk for attrition from treatment (OR=1.47, p < 0.001). The effect held upon controlling for age, gender, and co-morbid emotional symptoms; however, it was explained by child functional impairment. Similar effects were not found for the impact of symptoms on the family. Dropout was greater for adolescents (OR=1.43, p < 0.01) than younger children. Disadvantaged youth were more likely to drop out than more advantaged clients (OR=1.86, p < 0.001). Perceptions of difficulties in attending treatment were associated with a
Gain-Enhanced Cavity-Backed Cross Slot Antenna With Truncated Ground Walls

This article presents a new antenna structure using truncated ground walls (TGWs) for a gain enhancement implementation. The proposed antenna with TGWs is analyzed by an array of magnetic currents where the edge slot radiation of the proposed antenna is included. Also, the radiation at edge slots is operated by TGW, resulting in further enhancement for the antenna gain. To verify the proposed antenna with TGWs, an antenna module with a balun feed network was implemented and tested. The fabricated antenna gain was 10.1 dBi, and overall volume was <inline-formula> <tex-math notation="LaTeX">$50 \times 50 \times 6$ </tex-math></inline-formula> mm<sup>3</sup> (<inline-formula> <tex-math notation="LaTeX">$0.97\lambda _{0} \times 0.97\lambda _{0}\times 0.11\lambda _{0}$ </tex-math></inline-formula> at 5.8 GHz), which show a high gain to volume ratio compared to the conventional structures. The measured 10 dB impedance bandwidth (IBW) was 5.7% from 5.65 to 5.98 GHz, and 3 dB gain bandwidth was about 14% from 5.2 to 6.0 GHz.

Prevalence of Factors That Can Increase the Risk of Hip Fracture and Its Complications after Surgery

Background: hip fractures are defined as any fracture of the femur between the articular cartilage of the hip joint to 5 cm below the distal point of the lesser trochanter; they can occur at any age, they but are most common in the older persons. A worldwide incidence hip fractures are 1.6 million osteoporotic fractures of the hip in people aged 50 years and older in 2000, of which about 70% (1.14 million) were in women. Objectives: this study aimed to evaluate various postoperative complications and their risk factors in hip fracture patients in King Fahad Hospital in Saudi Arabia. Method: this prospective study enrolled patients with hip fractures who were subjected to hip fracture surgeries in the king Fahad Hospital in the period from 1/5/2010 to 31/1/2016. Detailed medical history,perioperative characteristics and post-operative characteristicswere collected from the patient's files. Results: the higher prevalence of hip fractures was founded among elderly patients with age range of 65 – 74 years. There was no significant correlations between age, gender, comorbidities (diabetes mellitus, anemia and walking of physical assistance), time of operation and post-operative complications (neurovascular, infection in joints, dislocation of the joint, loosing of the joint and post-operative disabilities) regarding readmission of hip fractures patients for the same reason within one year.While, there was a significant correlation between osteoporosis and readmission of hip fractures patients for the same reason within one year (P=0.049). Conclusion: medical complications such as neurovascular and infection in joints are encountered more frequently than surgical complications such as dislocation of the joint, loosing of the joint and post-operative disabilities. So, postoperative care is necessary to prevent medical complications.
Évaluation de la prise en charge des réactions allergiques aux urgences adultes de l’Hôpital Pellegrin à Bordeaux, à travers deux études observationnelles

Introduction : L’anaphylaxie est une pathologie dont la prevalence est en augmentation. Etant responsable de plus en plus d’hospitalisation et de deces, il est important que la prise en charge effectuee, soit la plus adequate possible. L’objectif de cette etude retrospective etait d’evaluer la concordance entre la prise en charge des reactions allergiques, realisee aux urgences, par rapport aux dernieres recommandations de la SFMU a ce sujet. Materiels et methode : Etude observationnelle, realisee entre le 1er decembre 2014 et le 30 juin 2015, puis sur la meme periode, un an plus tard. Etaient inclus, les patients se presentant pour un tableau d’allergie, au sein des urgences adultes de l’Hopital Pellegrin (a Bordeaux). Le but etait d’analyser et d’ameliorer la prise en charge des reactions allergiques, au sein de ces urgences. Resultats : 203 patients ont ete inclus (116 dans le premier groupe et 87 dans le second). L’âge moyen de la population etait de 36 ans, avec une proportion plus importante de femmes. Les patients ont presente majoritairement une symptomatologie cutaneo-muqueuse. Sur le plan therapeutique, on constate que 40 % des prescriptions sont adaptees. En comparant la prise en charge medicamenteuse des 2 groupes, on remarque des differences significatives. Notamment, les anti-histaminiques qui sont moins bien prescrit au stade 1 dans le second groupe (p < 0.01), tout comme les aerosols d’adrenaline en cas d’angio-œdeme (p = 0.02). Par contre, on observe une meilleure prescription des corticoides, qui sont moins donnes en cas d’urticaire dans le second groupe (p < 0.01). Dans presque un quart des cas, un bilan biologique standard est preleve malgre l’absence d’indication. Seulement 12 % des ordonnances de sortie sont redigees sans erreurs, sans difference significative entre les deux groupes. Les stylos d’adrenaline auto-injectables ne sont pas prescrits dans 10 % des cas environ. La moitie des patients ne sont pas informes de la necessite de prevoir une consultation aupres d’un allergologue. Conclusion : Il a ete remarque au cours de ce travail, une part importante de prescriptions medicamenteuses inadaptees. L’information des professionnels de sante ainsi que la realisation d’ordonnances de sortie pre-remplies pourrait ameliorer la prise en charge globale des reactions allergiques.
Choline derivatives immobilized on silica to catalyze transesterification reaction for production of glycerophosphocholine

Choline derivatives were covalently immobilized on the surface of γ -aminated silica. The obtained immobilized choline derivative was then successfully used for a transesterification reaction to produce glycerophosphocholine (GPC). Fourier transform infrared analysis and thermogravimetric analysis/differential thermal gravimetry indicated that the surface of the γ -aminated silica was covered by choline derivatives and the highest immobilization amount reached 1.1 mmol/g under optimal conditions. More importantly, the highest yield of GPC reached 97.9% during transesterification. With regard to GPC in food or medicine for human use, the immobilization technology can avoid catalyst contamination of the product and increase the safety of the product. The recyclability and stability of the immobilized choline derivative were excellent, as demonstrated by its use 20 times without any loss of productivity. A first-order kinetic model was employed and the relevant parameters were calculated to investigate kinetic characteristics of transesterification.
Data-driven approaches for unveiling the neurophysiological functions of the auditory system

: Typical neurophysiological experiments employ ‘‘hypothesis-driven’’ approaches: Researchers set a speciﬁc hypothesis, based on which stimuli and their parameters are chosen. However, there is always a concern that the hypothesis or stimulus parameter could be irrelevant to the essence of the brain function. The present paper review the authors’ recent studies that have applied some ‘‘data-driven’’ approaches as relatively hypothesis-free methodologies to traditional questions in auditory neurophysiology, such as neural frequency tuning and cortical topography. The results provide some new insights into the functional organization of the cortex and the optimality of the brain structure for auditory processing.
Prenatal Conditions and the Timing of Pregnancies

Prenatal Conditions and the Timing of Pregnancies Alfia Karimova Doctor of Philosophy Graduate Department of Economics University of Toronto 2016 Conditions experienced in utero have profound consequences for outcomes later in life. Much of this evidence is based on predictable variation in the prenatal environment. Such predictable variation can be avoided by mothers timing their pregnancies; however, this point has received little attention. In this dissertation, I study the timing of pregnancies to avoid foreseeable threats to fetal health, and the implications for the relationship between prenatal conditions and long-run outcomes. The first chapter contains a summary of the existing research on the timing of pregnancies and provides a framework for analyzing the evidence. In Chapter 2, I examine if women time pregnancy to avoid Ramadan, the Islamic month of fasting. Earlier research documents that pregnancies which are in utero during Ramadan lead to lower birthweight and a greater risk of fetal death. Using survey data from Indonesia, the world’s largest Muslim country, I find evidence of Ramadan avoidance. The probability of using contraceptives falls by 0.8 percentage points in the first month and by 1.2 percentage points in the second month after Ramadan, allowing mothers to conceive and give birth before the next cycle of Ramadan. Mothers learn to avoid exposure to Ramadan from their prior experience of pregnancy during Ramadan. There is no evidence of avoidance before the introduction of a program that distributed contraceptives, indicating that family planning programs may improve child health by allowing mothers to plan pregnancy to avoid predictable threats to prenatal health. In the final chapter, I study the consequences of prenatal exposure to dengue for infant health. Dengue is one of the most important mosquito-borne viral diseases in the world, yet evidence on its effects during pregnancy is inconclusive. Combining birth records data with data on dengue incidence in Puerto Rico, I find that one confirmed case of dengue per 1’000 during pregnancy leads to 0.53-0.76 percent fewer live births. Mothers are more likely to avoid dengue exposure in a given pregnancy if they have experienced dengue during a previous pregnancy. My research suggests that predictable variation in prenatal conditions often used in the fetal origins literature may not necessarily be treated as a natural experiment.
Description of BHK-21Persistent Infected Cell Inoculated with Infectious Bovine Rhinotracheitis Virus

Infectious Bovine Rhinotracheitis (IBR) disease caused by Bovine Herpesvirus-1 (BHV-1), this diseases include in strategic diseases. Based on the genotype, this virus divided into several subtypes, including subtype 1.1; subtype 1.2a and subtype 1.2b. The previous genotypic study revealed that based on the insertion-deletion of UL36 gene, samples divided into subtype 1.1 and subtype 1.2. This study aim was comparing phenotypic images of isolates from Lampung and Bukittinggi in MDBK and BHK-21 cells. Samples of swab nasal and tracheal organ obtained from Balai Veteriner Lampung and Balai Veteriner Bukittinggi. The samples were cultured on MDBK and BHK-21 monolayer cell of 2 days old obtained from Pusvetma. The Cytopathogenic Effects (CPE) in MDBK and BHK-21 observed on day 2. In the MDBK cell, the CPE found as the grape-like cluster and apoptosis. The CPE of BHK-21 cell line showed syncytium and indicated persistent infection. At day four on BHK-21 cell, it observed the particular infected cell that showed differences in cell shape between samples that have proximity to subtype 1.1 and subtype 1.2. The infected cell of subtype 1.1 group, appear as elongated shape and linear pattern near the center area. Inversely, the samples grouped as subtype 1.2 appear as rounded cell and circular pattern of the center area. Keywords—IBR, subtype 1.1, subtype 1.2b, UL36 gene, MDBK, BHK-21
Low Computational Sensing with Goertzel Filtering for Mobile Industrial IoT Devices

Internet-of Things (IoT) is getting connected to an increasing number of mobile devices such as autonomous vehicles, drones and robots. Termed as Mobile Industrial Internet-of Things (MI2oT) devices in this paper, a key requirement of these devices is to accurately estimate range and Doppler in various applications, in addition to data communication. Research efforts, therefore, include incorporating MI2-oT devices with high-data rate communications together with Frequency Modulated Continuous Wave Radar (FMCW) sensing capabilities. Range and Doppler sensing, in FMCW radars is undertaken by a two-stage Fast Fourier Transform (FFT) which is computationally demanding. It is challenging to design baseband processing with FFTs that can be implemented as low computational hardware or application specific integrated circuits (ASIC) in MI2oT devices. This paper, presents a novel range and Doppler sensing technique based on Goertzel filtering, leading to considerable reduction in computations compared to the FFT. FMCW radar with Goertzel filtering and FFT are examined in three cases viz., sensing the range and velocity of a car, vibration and respiration monitoring. Simulation results show a computation reduction of the order of 6.3×, 7.7× and 8.1× in giga-operations per second (GOPS) for the three cases respectively. The reduced computations increase the feasibility of implementing range and Doppler sensing in MI2oT devices which have restricted computational resources.
Dépense énergétique de repos en cancérologie. Étude clinique sur 390 patients

Contexte. En oncologie, la cachexie reste une cause importante de mortalite pour laquelle les ressources therapeutiques sont limitees et le role de la depense energetique de repos (DER) mal defini. L’objectif de cette etude est d’etudier le lien entre la DER et les marqueurs clinico-biologiques de cachexie en oncologie. Patients et methodes. Nous avons mesure la DER par calorimetrie indirecte chez des patients atteints de cancer. Nous avons defini selon l’equation de Harris et Benedict des patients hypermetaboliques (Hm) (DER mesuree >110% de la calculee), normometaboliques (Nm) (90%-110%) et hypometaboliques (Hom) (<90%). Nous avons etudie la perte de poids, le performance status (PS), l’albuminemie, le Nutritional Risk Index (NRI), les apports caloriques journaliers et calcule la balance energetique (apports caloriques journalier–DER). Resultats. Sur 390 patients on retrouvait 49% d’Hm, 30% de Nm et 21% d’Hom. Les Hm etaient plus denutris que les Nm: perte de poids etait de 5,9% vs 3,94 % (p=0,02) et la perte de poids > 5% de 67% vs 50% OR=4 p=0,014. L’albuminemie etait plus basse : 39,01 g/l vs 40,13 g/l p=0.042. Un NRI ≤97,5 representait 40% vs 27%, OR= 1,75 p= 0,036 et la CRP≥10 mg/L 52% vs 33% p=0,001 et le PS≥2 40% vs 29% OR=1,7 p=0,038. La balance energetique negative 45% vs 32% OR= 1,74 p=0,024. Compares aux patients ayant une balance energetique positive, les patients a balance negative etaient significativement plus denutris. Il n’existait pas de difference entre les Hom et les Nm. Conclusion. L’hypermetabolisme induit la cachexie par le biais d’une balance energetique negative chez les patients atteints de cancer.
Review on Application of Quaternary Ammonium Salts for Gas Hydrate Inhibition

Gas hydrate solids occurrence is considered as one of the serious challenges in flow assurance as it affects the hydrocarbon production significantly, especially in deep water gas fields. The most cost-effective method to inhibit the formation of hydrate in pipelines is by injecting a hydrate inhibitor agent. Continuous studies have led to a comprehensive understanding on the use of low dosage hydrate inhibitors such as ionic liquid and quaternary ammonium salts which are also known as dual function gas hydrate inhibitors. This paper covers the latest types of quaternary ammonium salts (2020–2016) and a summary of findings which are essential for future studies. Reviews on the effects of length of ionic liquids alkyl chain, average suppression temperatures, hydrate dissociation enthalpies, and electrical conductivity to the effectiveness of the quaternary ammonium salts as gas hydrate inhibitors are included.
Caracterización morfológica de nanotubos de ZnO

In this paper we present the procedure for zinc oxide (ZnO) nanotubes synthesis and their corresponding characterization. characterization. ZnO nanotubes were synthesized on previously optimized substrates, which is called "seed layer" and also on glass substrates in order to compare. The optimization of the seed layer was performed previously by ultrasonic spray pyrolysis by deposition of a ZnO thin film. Nanotubes growth was carried out by chemical bath deposition method. The substrates were immersed by facing the bottom of the glass beaker. Samples were studied using atomic force microscopy in order to study their morphological characteristics. Unlike other works, the synthesis was carried out in aqueous solution by utilizing zinc nitrate precursor and monoethanolamine as a control size agent. It was observed that uniform and hexagonal cross section nanotubes grew only on substrates with the seed layer deposition. On the other hand, position of the substrate induced a vertical and uniform growth of nanotubes in the normal direction to the substrate. Average diameter of nanotubes was 31.6 nm and average aspect ratio was 2.59 nm.
An Explicit and Scene-Adapted Definition of Convex Self-Similarity Prior With Application to Unsupervised Sentinel-2 Super-Resolution

Sentinel-2 satellite, launched by the European Space Agency, plays a critical role in various Earth observation missions. However, the spatial resolutions of Sentinel-2 images are different across its spectral bands, including four bands with a resolution of 10 m, six bands with a resolution of 20 m, and three bands with a resolution of 60 m. To facilitate the effectiveness of analyzing these images, super-resolving of the low-/medium-resolution bands to a higher resolution is desired. As in any image restoration inverse problems, we exploit image self-similarity, a commonly observed property in natural images, which underlies the state-of-the-art techniques, e.g., in image denoising. However, the design of self-similarity priors in nondiagonal inverse problems is challenging; often, a denoiser based on self-similarity is plugged into the iterations of an algorithm, without a guarantee of convergence in general. In this article, for the first time, we introduce a convex and scene-adapted regularizer built explicitly on a self-similarity graph directly learned from the Sentinel-2 images. We then develop a fast algorithm, termed Sentinel-2 super-resolution via scene-adapted self-similarity (SSSS). We experimentally show the superiority of SSSS over four commonly observed scenes, indicating the potential usage of our convex self-similarity regularization in other imaging inverse problems.
