We describe a radiological sign, “inside-outside sign,” observed during the cannulation of an expandable contrast-filled tubular structure in the human body. In this optical illusion, a catheter or guidewire appears to be outside the lumen when it is inside the lumen in reality. Knowing this rare optical illusion is essential to avoid mistaking it for a catheter or guidewire outside the lumen.

Hydroxyapatite bioceramics has attracted many material scientists as it is the main constituent of the bone and the teeth in human body. The synthesis of the bioceramics has been performed for years. Nowadays, the synthetic work is not only focused on the hydroapatite but also on the fluorapatite and chlorapatite bioceramics since later materials have also biological compatibility with human tissues; and they may also be very promising for clinic purpose. However, in comparison of the synthetic bioceramics with natural one on microstructure, a great differences were observed according to our previous results. We have investigated these differences further in this work since they are very important to appraise the synthetic bioceramics for their clinic application.The synthetic hydroxyapatite and chlorapatite were prepared according to A. Krajewski and A. Ravaglioli and their recent work. The briquettes from different hydroxyapatite or chlorapatite powders were fired in a laboratory furnace at the temperature of 900-1300°C. The samples of human enamel selected for the comparison with synthetic bioceramics were from Chinese adult teeth.

This is a combined study of two diffirent branches, photogrammetry and morphology of blood cells. The three dimensional quantitative analysis of erythrocytes using SEMP technique, electron computation technique and photogrammetry theory has made it possible to push the study of mophology of blood cells from LM, TEM, SEM to a higher stage, that of SEM P. A new path has been broken for deeply study of morphology of blood cells.In medical view, the abnormality of the quality and quantity of erythrocytes is one of the important changes of blood disease. It shows the abnormal blood—making function of the human body. Therefore, the study of the change of shape on erythrocytes is the indispensable and important basis of reference in the clinical diagnosis and research of blood disease.The erythrocytes of one normal person, three PNH Patients and one AA patient were used in this experiment. This research determines the following items: Height;Length of two axes (long and short), ratio; Crevice in depth and width of cell membrane; Circumference of erythrocytes; Isoline map of erythrocytes; Section map of erythrocytes.

Peningkatan suhu tubuh  menyebabkan rasa tidak nyaman, gelisah pada anak, sehingga waktu untuk istirahat menjadi terganggu.Tatalaksana pada anak dengan demam dapat dilakukan dengan metode farmakologi dan non farmakologi. Tepid water spongingmerupakan tatalaksana non farmakologi. Konservasi adalah serangkaian sistem agar tubuh manusia mampu menjalankan fungsi, beradaptasi untuk melangsungkan kehidupan. Perawat mempunyai peran untuk membantu anak dalam mengatasi gangguan termoregulasi. Karya ilmiah ini bertujuan untuk mengetahui efektifitas penurunan suhu tubuh menggunakan tepid water sponging dengan pendekatanl konservasi Levine di ruang rawat infeksi. Efektifitas diukur dalam pemberian asuhan keperawatan berdasarkan proses keperawatan yang terdapat dalam model konservasi Levine yaitu: pengkajian, menentukan trophicognosis, menentukan hipotesis, intervensi dan evaluasi. Terdapat lima kasus yang dibahas. Hasil penerapan model konservasi Levine mampu meningkatkan kemampuan anak dalam mempertahankan fungsi tubuh dan beradaptasi terhadap perubahan. Kombinasi tepid water sponging dan terapi farmakologi mampu mengatasi demam dengan cepat dibanding terapi farmakologi.   Kata kunci: termoregulasi, tepid water sponging, teori model konservasi Levine   REDUCTION OF BODY TEMPERATURE USING TEPID WATER SPONGINGWITH THE LEVINE CONSERVATION APPROACH   ABSTRACT Increased body temperature causes discomfort, anxiety in children, so that the time to rest becomes disturbed. Management of children with fever can be done by pharmacological and non-pharmacological methods. Tepid water sponging is a non-pharmacological treatment. Conservation is a series of systems so that the human body is able to function, adapt to life. Nurses have a role to help children overcome thermoregulation disorders. This scientific work aims to determine the effectiveness of decreasing body temperature using tepid water sponging with the approach of Levine conservation in the infectious care room. Effectiveness is measured in the provision of nursing care based on the nursing process contained in the Levine conservation model, namely: assessment, determining trophicognosis, determining hypotheses, intervention and evaluation. There are five cases discussed. The results of the application of the Levine conservation model are able to improve the ability of children to maintain body functions and adapt to changes. The combination of tepid water sponging and pharmacological therapy is able to overcome fever quickly compared to pharmacological therapy.   Keywords: thermoregulation, tepid water sponging, Levine conservation model theory

The Swiss geologist and mineralogist Louis-Albert Necker belonged to a family rich in scientific celebrities. Though a professor at the Académie de Genève for 25 years and author of numerous publications, he is mainly remembered today for his description of the “Necker cube” optical illusion and for leaving Geneva to spend the last 20 years of his life in Portree on the Isle of Skye. As a first step towards assessing Necker's contribution to science, a full list of his publications is presented, with comments about their citation in previous bibliographies and about published translations and abridgements. Information about the surviving specimens from his scientific collections, most of which are in the Muséum d'histoire naturelle de Genève, is also presented.
