From the above protocols, it can be seen that the clinical picture of poisoning was very similar in all animals. Usually the first symptom was lethargy, to which inactivity was added; lethargy intensified and at times passed, as it were, into a stunned state. Dispatch of the gastrointestinal canal was not built up significantly and for a short time, and in cats, more or less pronounced salivation appeared.

Looking through the stories of patients who passed through our hands in 1906 in a difficult department of the Kazan District Hospital, we drew attention to a rather rare case of idiocy, which, unfortunately, we had to observe for a very short time, why its study was of a general nature, and there is much in the clinical picture seemed unclear. However, we had to perform an autopsy on this patient and, examining his brain, we hoped to find the key to understanding those phenomena that seemed incomprehensible during his lifetime.

Reflex epilepsy, where epileptic seizures are triggered by specific sensory stimuli, affects 4–7% of patients suffering from epilepsy. Reading epilepsy, where all or almost all epileptic seizures are induced by reading, is a very rare form of reflex epilepsy. Two types of this disease have been distinguished: the most common type is caused by sudden muscle jaw contractions (myoclonic variant) and it lasts for a very short time (for example few seconds), while the second type is characterised by focal alexia seizures (focal variant with alexia). The article highlights the clinical picture and treatment of reading epilepsy in a 18-yearold patient. In this case, seizures were always caused by at least 2 hours of continuous reading and were preceded by jaw myoclonus. The treatment included sodium valproate and levetiracetam.

AbstractReplication failures were among the triggers of a reform movement which, in a very short time, has been enormously useful in raising standards and improving methods. As a result, the massive multilab multi-experiment replication projects have served their purpose and will die out. We describe other types of replications – both friendly and adversarial – that should continue to be beneficial.

AbstractWe present an analysis of short time-scale intensity variations in the coronal green line as obtained with high time resolution observations. The observed data can be divided into two groups. The first one shows periodic intensity variations with a period of 5 min. the second one does not show any significant intensity variations. We studied the relation between regions of coronal intensity oscillations and the shape of white-light coronal structures. We found that the coronal green-line oscillations occur mainly in regions where open white-light coronal structures are located.

We have studied the destruction of rabbit muscle actin filaments by osmium tetroxide (OSO4) to develop methods which will preserve the structure of actin filaments during preparation for transmission electron microscopy.Negatively stained F-actin, which appears as smooth, gently curved filaments in control samples (Fig. 1a), acquire an angular, distorted profile and break into progressively shorter pieces after exposure to OSO4 (Fig. 1b,c). We followed the time course of the reaction with viscometry since it is a simple, quantitative method to assess filament integrity. The difference in rates of decay in viscosity of polymerized actin solutions after the addition of four concentrations of OSO4 is illustrated in Fig. 2. Viscometry indicated that the rate of actin filament destruction is also dependent upon temperature, buffer type, buffer concentration, and pH, and requires the continued presence of OSO4. The conditions most favorable to filament preservation are fixation in a low concentration of OSO4 for a short time at 0°C in 100mM sodium phosphate buffer, pH 6.0.

Intermediate high temperature tempering prior to subsequent reaustenitization has been shown to double the plane strain fracture toughness as compared to conventionally heat treated UHSLA steels, at similar yield strength levels. The precipitation (during tempering) of metal carbides and their subsequent partial redissolution and refinement (during reaustenitization), in addition to the reduction in the prior austenite grain size during the cycling operation have all been suggested to contribute to the observed improvement in the mechanical properties. In this investigation, 300M steel was initially austenitized at 1143°K and then subjected to intermediate tempering at 923°K for 1 hr. before reaustenitizing at 1123°K for a short time and final tempering at 583°K. The changes in the microstructure responsible for the improvement in the properties have been studied and compared with conventionally heat treated steel. Fig. 1 shows interlath films of retained austenite produced during conventionally heat treatment.

Lysosomal Diseases

There are four lysosomal diseases of which the neuronal ceroid lipofuscinosis is the rarest. The clinical presentation and their characteric abnormal ultrastructure subdivide them into four types. These are known as the Infantile form (Santavuori-Haltia), Late infantile form (Jansky-Bielschowsky), Juvenile form (Batten-Spielmeyer-Voght) and the Adult form (Kuph's).An 8 year old Omani girl presented wth myclonic jerks since the age of 4 years, with progressive encephalopathy, mental retardation, ataxia and loss of vision. An ophthalmoscopy was performed followed by rectal suction biopsies (fig. 1). A previous sibling had died of an undiagnosed neurological disorder with a similar clinical picture.

Short Time

Strong solid state bonds are routinely produced between physical vapor deposited (PVD) silver coatings deposited on sputter cleaned surfaces of two dissimilar metal parts. The low temperature (200°C) and short time (10 min) used in the bonding cycle are advantageous from the standpoint of productivity and dimensional control. These conditions unfortunately produce no microstructural changes at or near the interface that are detectable by optical, SEM, or microprobe examination. Microstructural problems arising at these interfaces could therefore easily go undetected by these techniques. TEM analysis has not been previously applied to this problem because of the difficulty in specimen preparation. The purpose of this paper is to describe our technique for preparing specimens from solid state bonds and to present our initial observations of the microstructural details of such bonds.

Highly polyploid somatic nucleus (macronucleus) of ciliate Bursaria truncatella under goes severe changes in morphology during cell division. At first, macronucleus (Ma) condences, diminishes in size and turns perpendicular to longitudinal axis of the cell. After short time, Ma turns again, elongates and only afterwards the process of division itself occurs. The biological meaning of these phenomena is not clear.Localization of RNA in the cells was performed on sections of ciliates B. truncatella, embedded in “Lowicryl K4M” at various stages: (1) before cell division (Figs. 2,3); (11) at the stage of macronucleus condensation; (111) during elongation of Ma (Fig.4); (1111) in young cells (0-5min. after division). For cytochemical labelling we used RNaseAcolloidal gold complexes (RNase-Au), which are known to bind to RNA containing cell ularstructures with high specificity. The influence of different parameters on the reliability and reproducibility of labelling was studied. In addition to the factors, discussed elsewhere, we found that the balance of mono- and bivalent cations is of great significance.
