First study on oxyuriosis in horses from Algeria: Prevalence and clinical aspects

The present study was carried out the Tiaret region, on horses belonging to the Chaouchaoua National Haras, ONDEEC and on two private farms during the period from February 05th to April 17th, 2019. It aims to assess the overall prevalence of equine oxyuriosis in the area and to describe the most dominant clinical signs of this parasite infection. Scotch tape test was applied on 176 horses randomly selected and the microscopic observation of slides was carried out at the parasitology laboratory of the Veterinary institute of Tiaret. The overall prevalence of Oxyuris equi was 38.64% with females being more infected (37.04%) than males (20.45%). The prevalence of oxyuriosis was higher in fillies (70%) than in foals (48.39%).The high prevalence of Oxyuris equi was recorded in the private farms with a percentage of 85% and 44% in farm 1 and 2, respectively. The more commonly clinical signs were tail rubbing in 42% and scratching in 32% of positive horses.Equine oxyuriosis is a common infection in the study area and requires the application of hygienic measures with more therapeutic and preventive care.

Comparison of Clinical Assessment and Adhesive-Tape Laboratory Microscopic of Sarcoptes scabiei for Scabies Diagnostic

Scabies infestation caused by Sarcoptes scabiei mite that infected the skin by making the tunnel burrow. Diagnosis of scabies infestation commonly relies on clinical assessment (CA). However, some scabies symptoms are similar to other diseases. Diagnosis of confirmed scabies can be made by identifying egg or Sarcoptes scabiei mite or scybala through skin scraping laboratory microscopic examination, which was the adhesive tape microscopic (AT) a noninvasive alternative. We aimed to compare the scabies diagnostic accuracy of CA and AT in Islamic Boarding School. This study was an analytical observational cross-sectional study. The population was 94 students of Islamic Boarding School, determining the sample base on purposive sampling technique. There were 34 samples with presumptive scabies analyzed with CA by two clinicians and AT by two trained laboratory technicians. The result showed that the number of patients who positive scabies by CA was 14 (41.18 percent) and 31 (91.18 percent) by AT. Sensitivity was 41.93 percent for CA and 92.85 percent for AT, and the difference was significantly based on Cohen's kappa (ⱪ=0.024). The number of positive cases with both techniques was 13 (38.24 percent). The number of patients positive with only CA was 1 (2.93 percent), and only AT was 18 (22.9 percent). The accuracy of CA was only 44,11 percent. The study concluded that CA is low accuracy than AT. The adhesive tape test is easy, needs no expensive equipment. It is recommended that adhesive tape test for screening purposes. The appropriate comprehensive of both methods for scabies diagnostic is highly recommended.

AVERAGE TOTAL HEMISPHERIC EMISSIVITY MEASUREMENT IN THE LWIR SPECTRUM FOR ADHESIVE TAPES USED IN THE THERMOGRAPHY TAPE TEST

Thermographers often use comparative methods to estimate surfaceemissivity. Among the most used is the tape method. In this method a knownemissivity tape in the LWIR (Long Wavelength Infrared) spectrum is placedon the surface to be inspected. After thermal equilibrium, the temperature ofthe tape and the surface under inspection must be the same. In this case, thetemperature observed on the tape is the reference temperature. The emissivityof the surface must then be changed until the reference temperature isreached. It is common practice to admit the value of the emissivity of theadhesive tape as 0.95, there are few studies that present these data withmetrological rigor, which leads to doubts about the emissivity of thecommercial tapes. In this work, experiments were performed on Tekbond,Double A, 3M 101, Rapix, Altape, adhesive tapes for temperatures of 50, 55,60, 65 and 70ºC. An experimental apparatus was developed through which itwas possible to estimate surface reflection, transmission and atmosphericemission for one and two layers of tapes, in order to make emissivitymeasurements possible. Through the data it was possible to statisticallyestimate the LWIR average total hemispheric emissivity as well as theacceptance range to 95% certainty, being therefore equal to ε=0.94±0.03. Itis possible to arm, therefore, that the value of 0.95, usually used as emissivityof the adhesive tape, is extremely reasonable because it is 0.01 of the averagevalue of the Gaussian distribution calculated by this work.

A Facile and Rapid Fabrication of Multifunctional Color-Tuned Titanium

In this article, a strategy for the fabrication of color-tuned titanium using a torch was developed. The torch was used to manufacture a layer of titanium dioxide on titanium substrates. The reaction time and requirements were reduced compared to the anodization process. Various colors appeared depending on the time of torch heating, and this torched-titanium substrate was treated with octadecyltriethoxylsilane (ODTS) to gain superhydrophobic properties for self-cleaning. Scanning Electron Microscope (SEM), Raman spectroscopy, and Atomic Force Microscope (AFM) were used for surface analysis. Besides, the mechanical and ODTS stability of the surface were evaluated through a cross-cut adhesion tape test and water contact angle measurement, proving that the torch is a suitable fabrication process for multifunctional color-tuned titanium.

Terowongan dan tungau sulit ditemukan pada penderita skabies disebabkan oleh kerusakan kulit karena garukan dan jumlah tungau yang sedikit.CHARACTERISTICS OF CARDINAL SIGNS OF SCABIES IN SANTRI AT ISLAMIC BOARDING SCHOOLSScabies is a contagious skin infection. This disease can be diagnosed by finding two of the four kardinal signs, namely itching at the site of predilection, especially at night, concerning a group of people, the presence of tunnel lesions in the skin and the discovery of mites in skin scrapings. This study aims to determine the characteristics of kardinal signs in scabies. The study was conducted at one pesantren in Bandung from March to October 2019. Subjects in this study were 43 person with scabies. Tunnel checks are performed with a burrow ink test and lesion scrapings are carried out using an adhesive tape technique. The data of this descriptive research are analyzed by univariate analysis. The results showed that papules were the most common lesion morphology (86%), most lesion locations were found between fingers (65.1%), positive examination results on the burrow ink test were 14% and all adhesive tape test showed results negative. Tunnels and mites are difficult to find in people with scabies due to skin damage due to scratching and a small amount of mites.

Adhesion Strength of Hydroxyapatite Coating on Titanium Materials (Ti-6Al-4V ELI) for Biomedical Application

Implantasi menggunakan material titanium Ti-6Al-4V ELI masih memiliki keterbatasan yaitu osseointegrasi yang rendah karena bersifat kurang bioaktif. Hidroksiapatit digunakan sebagai bahan pelapisn meningkatkan bioaktivitas material dan ikatan material dengan jaringan tulang. Material Ti-6AL-4V ELI (kepingan) dilapisi dengan hidroksiapatit menggunakan metode electrophoretic deposition, dengan variasi voltase (5,8, dan 11 volt) selama 5 menit dan variasi waktu deposisi (5,8, dan 11 menit) dengan voltase 8 volt. Pengujian kekasaran dan kekuatan adhesi lapisan hidroksiapatit pada permukaan material dilakukan secara kualitatif. Hasil penelitian yang diperoleh menunjukkan bahwa metode EPD dapat digunakan untuk melapisi material Ti-6Al-4V ELI dengan hidroksiapatit. Massa partikel penyusun lapisan hidroksiapatit relatif dipengaruhi oleh perlakuan waktu deposisi karena terdapat perubahan ketebalan lapisan. Akan tetapi, susunan partikel relatif dipengaruhi oleh daya yang mengakibatkan migrasi partikel yang akan berpengaruh terhadap ikatan lapisan pada permukaan material. Perlakuan voltase 8 volt selama 5 menit menghasilkan kekasaran pemukaan material dilapisi hidroksiapatit Ra 0,88 dan kerusakan lapisan setelah cross cut tape test adalah 2,25% yang berarti lapisan mengalami adhesi dengan baik pada permukaan material. Dengan masa hidroksiapatit relatif tinggi (0,3 mg), lapisan tersebut menutupi permukaan material titanium dengan baik (surface coverage 82,1%) memiliki ketebalan rata-rata (73,3 μm). Hasil yang diperoleh diharapkan sesuai untuk aplikasi biomedis.

Characterization and Analysis of Metal Adhesion to Parylene Polymer Substrate Using Scotch Tape Test for Peripheral Neural Probe

This paper presents measurement and FEM (Finite Element Method) analysis of metal adhesion force to a parylene substrate for implantable neural probe. A test device composed of 300 nm-thick gold and 30 nm-thick titanium metal electrodes on top of parylene substrate was prepared. The metal electrodes suffer from delamination during wet metal patterning process; thus, CF4 plasma treatment was applied to the parylene substrate before metal deposition. The two thin film metal layers were deposited by e-beam evaporation process. Metal electrodes had 200 μm in width, 300 μm spacing between the metal lines, and 5 mm length as the neural probe. Adhesion force of the metal lines to parylene substrate was measured with scotch tape test. Angle between the scotch tape and the test device substrate changed from 60° to 90° during characterization. Force exerted the scotch tape was recorded as the function of displacement of the scotch tape. It was found that a peak was created in measured force-displacement curve due to metal delamination. Metal adhesion was estimated 1.3 J/m2 by referring to the force peak and metal width at the force-displacement curve. Besides, the scotch tape test was simulated to comprehend delamination behavior of the test through FEM modeling.

The study of comorbid pathologies that influence the severity of the disease and impair the effectiveness of treatment is carried out to optimize the treatment of the main disease. Materials and methods. The total of 132 medical students was divided into two groups: the 1st group: 56 students who didn`t have acne elements, the 2nd group: 76 students with mild acne vulgaris. At the baseline and after 12 months epithelial tape-test was performed to define Demodex mites presence. The theory of chances was used to assess the impact of acne on the occurrence of Demodex mites. Results. The presence of Demodex mites was observed in 3.57% of students in the 1st group and in 21.05% of students in the 2nd group on repeated tape-test. The probability value (P) among students of the 1st group was P1 = 0.037; among students of the 2nd group – P2 = 0.266. The odds (O) indicator in the 1st group of students without acne elements was O1 = 0.04, in the 2nd group diagnosed with acne – O2 = 0.21. The odds ratio (OR) value in the case/control groups was 7.20. Confidence intervals (95% CI) – (1.582, 32.765): the lower limit of the confidence interval (2.019, + ∞); the upper limit of the confidence interval (-∞, 25680). The significance test p-value was 0.00533. Conclusion. Acne vulgaris is one of the aggravating factor that increases the risk of Demodex mites.
