Treatment of Specific Types of Nystagmus
2007
■ The function of the ocular motor system is to hold images stable on the fovea. The vestibular system and the vestibulo-ocular reflex (VOR) also play an important role in this function. The VOR connects the peripheral vestibular endorgans – the semicircular canals and otoliths – with their appropriate pair of eye muscles via a three-neuronal arc.
Poļu studentu korporācijas Welecja piemiņas plāksne
2020
Raksts satur informāciju par poļu studentu korporāciju Welecja piemiņas plāksni, kas glabājās LU Muzeja krājumā. Rakstā tiek analizēta piemiņas plāksnes memoriālā nozīme kopīgajā Polijas un Latvijas valstu vēsturē, uzsverot poļu studentu korporāciju aizsākumus Baltijā. Uzmanības centrā ir Welecja korporants Ignācijas Moscickis, kurš studējis ir Rīgas Politehnikumā/Rīgas Politehniskajā institūtā, kā arī sniedzis ieguldījumu demokrātijas saglabāšanas mēģinājumā Polijas valstī.
Molecular markers for identified neuroblasts in the developing brain of Drosophila.
2003
The Drosophila brain develops from the procephalic neurogenic region of the ectoderm. About 100 neural precursor cells (neuroblasts) delaminate from this region on either side in a reproducible spatiotemporal pattern. We provide neuroblast maps from different stages of the early embryo (stages 9, 10 and 11, when the entire population of neuroblasts has formed), in which about 40 molecular markers representing the expression patterns of 34 different genes are linked to individual neuroblasts. In particular, we present a detailed description of the spatiotemporal patterns of expression in the procephalic neuroectoderm and in the neuroblast layer of the gap genes empty spiracles, hunchback, hu…
Enteromyxum leei (Myxozoa: Myxosporea) infection in gilthead sea bream (Sparus aurata): Immune-related studies
2013
La presente tesis doctoral estudia diversos aspectos de la enteromixosis de la dorada, relacionados principalmente con la transmisión y la caracterización del parásito, con los factores que afectan a su establecimiento en el hospedador y a la interacción parásito-hospedador, y con la respuesta inmunitaria inducida por el parásito. En primer lugar, se desarrolló un nuevo método de transmisión de E. leei, que mejora los resultados obtenidos por los hasta ahora disponibles. El parásito se transmitió con éxito a doradas mediante intubación por vía anal de raspados intestinales de peces infectados. Con este método, se consiguió una infección más rápida y extensa que por efluente y por cohabitaci…
Muscle-Tendon Interaction During Human Dolphin-Kick Swimming
2019
Without high impact forces, it is not clear how humans can utilize tendon elasticity during low-impact activities. The purpose of the present study was to examine the muscle-tendon behavior together with the electromyographic (EMG) activities of the vastus lateralis (VL) muscle during the human dolphin-kicking. In a swimming pool, each subject (n = 11) swam the 25 m dolphin-kicking at two different speeds (NORMAL and FAST). Surface EMGs were recorded from the VL and biceps femoris (BF) muscles. Simultaneous recordings of the knee joint angle by electro-goniometer and of the VL fascicle length by ultrasonography were used to calculate the muscle-tendon unit and tendinous length of VL(L-MTU a…
ESRA19-0618 Vulnerability of different nerves to intrafascicular injection with different needle bevel types and needle angles: a mathematical model
2019
Background and aims Intrafascicular injection of a local anesthetic, its toxicity, and direct needle trauma to nerve tissue are generally considered the primary reasons for nerve injury after intraneural injection. We hypothesize that the only way that the local anesthetic can enter the fascicle is if at least 80% of the distal needle orifice is inside the fascicle. the aim of this study was to calculate the theoretical vulnerability of nerve fascicles given their actual sizes and that of different needle openings. Methods We superimposed microscopic images of two routinely used nerve block needles (a 22-G, 15 ‘StimuplexOD’ needleand a 22-G, 30 ‘StimuplexOUltra 360O’ needle) over microscopi…
