Spatial Genomic Approaches to Investigate HOX Genes in Mouse Brain Tissues.

Spatial transcriptomic tools are an upcoming and powerful way to investigate targeted gene expression patterns within tissues. These tools offer the unique advantage of visualizing and understanding gene expression while preserving tissue integrity, thereby maintaining the spatial context of genes. Curio is a robust spatial transcriptomic tool that facilitates high throughput comprehensive spatial gene expression analysis across the entir e transcriptome with high efficiency. Here, we present a bioinformatics protocol for performing whole transcriptome gene expression analysis of mouse brain tissue using Curio. Specifically, we demonstrate using computational techniques to visualize expression patterns of various HOX genes in the mouse brain.

Parasitoids, polydnaviruses and endosymbiosis.

Symbiotic associations traditionally have been treated as evolutionary curios rather than as a major source of evolutionary innovation. Recent research on a wide variety of organisms is changing this view and is breaking down the barriers between the traditional categories of parasitism, commensalism and mutualism, to produce a more flexible view of multispecific interactions. An especially abundant, but little discussed, mutualism exists between parasitoid wasps in the superfamily Ichneumonoidea and a novel form of DNA viruses known as polydnaviruses. Mutualisms between viruses and eukaryotes are not often reported, although as many as 100 000 species of organisms may exhibit this unusual association. In this review Jim Whitfield considers what is known about the parasitoid-polydnavirus relationship and how (and from what) it might have arisen.

Food safety and consumers' attitude in a new EU member state. A case study of Hungary.

Food safety problems are gaining importance throughout Europe. National food safety strategies are required and in the center of these strategies are consumers. The aim of our study was to analyse the behavior of Hungarian consumers and their food safety-related knowledge based on cluster analysis of principal component scores. We have identified five clusters: 'uncertain curios', 'optimistic technocrats', 'indifferent', 'distrustful' and 'incoherent' consumers. The name of each group is reflecting the most characteristic feature of the cluster. Furthermore, their socio-economic and educational background was dominant, as well. Consequently, our most important aim should be to strengthen the efficiency of risk communication towards consumers relating to food safety issues if we want to preserve their fragile confidence.

Treatment of the carcinoid tumor and the malignant carcinoid syndrome.

Certainly in treatment of the carcinoid tumor surgery has a well-established curative and palliative potential. The primary challenge is a knowledgable marriage between stage of disease and aggressiveness of operative procedure. Nonsurgical treatment of the malignant disease per se has thus far not produced optimum results and, in the opinion of this author, should still be confined to a clinical research setting. It would seem very doubtful, however, that the more mundane types of trials, empirically testing drug after drug and arbitrarily concocted drug combinations, is the most productive road to follow. There is an evident need for more sophisticated approaches to this tumor, which has unique metabolic characteristics that should be pharmacologically exploitable. Past experience has indicated that such a setting may permit dramatic therapeutic accomplishment. There is a strong need for animal models or established cell lines which would facilitate preclinical therapeutic exploration. The carcinoid syndrome presents an unparalleled opportunity for fundamental physiologic observations and for experimental therapeutic study that can have applicability not only in palliating the syndrome itself but also in the management of other pathophysiologic states that may involve more subtle abnormalities of the same hormonal mechanisms. The patient with the carcinoid tumor should not just be a fascinating curio for grand rounds exhibition. He should be a focal point for research involving an experienced, multidisciplinary clinical team supported by devoted basic scientists. If our patient resources and efforts can be concentrated in this manner, the carcinoid should be a strong candidate for the next medically curable human cancer.

The conjoined twins of Löwen.

This paper discusses an unusual etching of unlike-sex conjoined twins of the syncephalus type dated 1547. The authenticity of the case is discussed in terms of the biological plausibility of such twins and in the light of mediaeval understanding of the twinning process. Unlike-sex syncephalic twins may occur as a result of dispermic fertilisation, or be an erroneous depiction of an asymmetrical anomaly of the external genitalia of a like-sex pair, mimicking the genitals of the other sex. On the other hand, the Löwen etching conforms with mediaeval beliefs that conjoined twins are divine punishment and therefore were used for ecclesiastical and perhaps commercial purposes. The historical context of the drawing, in which the relation between religion, media, and medicine satisfied the eagerness of the public for curios of Nature, is no longer valid. Thus the Löwen etching opens a window to the past from which modern medicine can be appreciated.

Three new species of Isospora Schneider, 1881 (Apicomplexa: Eimeriidae) from the lesser seed-finch, Oryzoborus angolensis (Passeriformes: Emberizidae) from Brazil.

Three new coccidian (Apicomplexa: Eimeriidae) species are reported from the lesser seed-finch, Oryzoborus angolensis from Brazil. Sporulated oocysts of Isospora curio n. sp. are spherical to subspherical; 24.6 x 23.6 (22-26 x 22-25) microm, shape-index (SI, length/width) of 1.04 (1.00-1.15). Oocyst wall is bilayerd, approximately 1.5 microm thick, smooth and colourless. Micropyle and oocyst residuum are absent. The sporocysts are ovoid, 13.2 x 10.9 (15-17 x 10-13) microm, SI = 1.56 (1.42-1.71), with a small Stieda body and residuum composed of numerous granules scattered among the sporozoites. Sporozoites are elongated and posses a smooth surface and two distinct refractile bodies. Oocysts of Isospora braziliensis n. sp. are spherical to subspherical, 17.8 x 16.9 (16-19 x 16-18) microm, with a shape-index of 1.06 (1.00-1.12) and a smooth, single-layered wall approximately 1 microm thick. A micropyle, oocyst residuum and polar granules are absent. Sporocysts are ellipsoid and slightly asymmetric, 13.2 x 10.8 (12-14 x 9-12) microm, SI = 1.48 (1.34-1.61). Each sporocyst contains a barely visible Stieda body and a residuum composed numerous of granules. Sporozoites are elongated and each of them contains two distinct refractile bodies. Oocysts of Isospora paranaensis n. sp. are subspherical to broadly ellipsoid 24.3 x 19.8 (22-26 x 18-22) microm, SI = 1.22 (1.15-1.38) with smooth single-layered wall approximately 1.5 microm thick. A micropyle and oocyst residuum are absent, but one distinct ellipsoid polar granule (2.5-3.5 x 1.5-2.5 microm) is present. Sporocyst are ovoid, 15.7 x 10.1 (14-18 x 8-12) microm, SI = 1.46 (1.31-1.72), with distinct Stieda and sub-Stieda bodies. Each sporocyst contains a spherical sporocyst residuum, 4 microm in diameter All described isosporan species represent a possible cause of acute coccidiosis for O. angolensis in captivity.

[Historical study of the moth repellent, "Fujisawa Camphor" (7) - selling price and packaging.].

The selling price of "Fujisawa Camphor" has increased 1,000-fold in the 100 years since it first went on sale. This 1,000-fold increase is not high at all. The price of "Fujisawa Camphor" was not low in the 1980s, one of grounds for setting the price was the damage caused by moths to expensive Japanese clothes and curios. For packaging in the Edo era, being wrapped in paper was the mainstream form, but modern-age packaging shifted to a cardboard box. As for "Fujisawa Camphor", a beautiful design was created for the cardboard.

[Anatomic preparations in the Petersburg "art chamber"].

The first museums on history of nature were opened in early Enlightenment and had originated from baroque curio galleries at most of the European courts. Peter the Great, too, had his "Art Chamber" converted to a universal museum primarily designed to didactic purposes. Much of the space was devoted to anatomic and teratological exhibits. To complete these collections, Peter repeatedly ordered all malformations to be handed over ("Monster Decree"). When travelling abroad, he purchased anatomic, zoological, botanic, and mineralogical collections, such as the famous collection previously owned by Frederik Ruysch in Amsterdam, with injected anatomic specimens with period-style decorations. The Art Chamber collection was later on described by K. W. Burdach, anatomist, and K. E. v. Baer, anthropologist. Many of its exhibits are still at show.

Speaking modifies voice-evoked activity in the human auditory cortex.

The voice we most often hear is our own, and proper interaction between speaking and hearing is essential for both acquisition and performance of spoken language. Disturbed audiovocal interactions have been implicated in aphasia, stuttering, and schizophrenic voice hallucinations, but paradigms for a noninvasive assessment of auditory self-monitoring of speaking and its possible dysfunctions are rare. Using magnetoencephalograpy we show here that self-uttered syllables transiently activate the speaker's auditory cortex around 100 ms after voice onset. These phasic responses were delayed by 11 ms in the speech-dominant left hemisphere relative to the right, whereas during listening to a replay of the same utterances the response latencies were symmetric. Moreover, the auditory cortices did not react to rare vowel changes interspersed randomly within a series of repetitively spoken vowels, in contrast to regular change-related responses evoked 100-200 ms after replayed rare vowels. Thus, speaking primes the human auditory cortex at a millisecond time scale, dampening and delaying reactions to self-produced "expected" sounds, more prominently in the speech-dominant hemisphere. Such motor-to-sensory priming of early auditory cortex responses during voicing constitutes one element of speech self-monitoring that could be compromised in central speech disorders.

Visual-vestibular interaction studied with stroboscopically illuminated visual patterns.

Horizontal DC-electrooculograms were recorded in subjects rotating on a horizontal turntable sinusoidally at 0.1 Hz and 35 to 40 degrees amplitude. The subjects either fixated a stroboscopically illuminated vertically striped pattern (1.15 to 3.45 degrees period) rotating with the turntable or initiated Sigma-OKN before the rotation began and tried to maintain Sigma-OKN during rotation. In a third paradigm, interaction of vestibulo-ocular reflex (VOR) and Phi-OKN was studied. VOR-suppression by fixation was complete within the limits of EOG-recording precision (+/- 1 degree X s-1) for flash frequencies fs greater than 10 flashes X s-1. VOR-suppression decreased monotonically with fs between 10 and 1 flashes X s-1. A similar dependency on fs was found for VOR-suppression during Sigma- or Phi-OKN. Above 10 flashes X s-1 VOR-suppression remained incomplete; below 5 flashes X s-1 VOR-suppression was stronger with the Sigma-OKN paradigm than during fixation and depended on spatial frequency of the pattern. During sinewave rotation of the subject the perceived speed Vp of Sigma-movement correlated to the movement of gaze in space and not to the movement of the eye in head. In a control experiment with normal optokinetic stimulation, OKN-suppression by fixating a small flashing target was found to depend on fs in a similar way as VOR-suppression in the experiments described above.

Annoyance and health risk caused by military low-altitude flight noise.

Effects of noise of low-flying military jet aircraft were investigated from demoscopic and epidemiological points of view. Areas with different low-altitude flight noise exposure were compared with one another as to subjective annoyance, casual blood pressure and ear symptoms. With the same energy equivalent sound pressure level (Leq), the subjective disturbance caused by military low-altitude flight noise was essentially greater than that due to ordinary flight noise (in the neighbourhood of civil airports). A comparison of several areas revealed that frequencies of ear symptoms (tinnitus lasting more than one hour and permanent hearing threshold shifts of greater than 30 dB) were higher only in areas where maximal flight noise levels considerably exceeded 115 dB (A) accompanied by rapid noise level increases. Blood pressure measurements yielded significantly higher values (group difference 9 mm Hg systolic) in girls living in these highly exposed areas. Acoustic limits are proposed with respect to public health.

The use of olfaction in the foraging behaviour of the golden-mantled flying fox, Pteropus pumilus, and the greater musky fruit bat, Ptenochirus jagori (Megachiroptera: Pteropodidae).

Double-choice experiments with three adult males of the little golden-mantled flying fox, Pteropus pumilus, and ten adult greater musky fruit bats, Ptenochirus jagori (both Megachiroptera: Pteropodidae), demonstrate that they are able to discriminate accurately between an empty dish and a dish containing fruits of one of several species by odour alone. Tests were run using fruits of six fruit species for Pteropus pumilus and five fruit species for Ptenochirus jagori. The fruit species used are known to be consumed in the wild by Ptenochirus jagori and are, with two exceptions, species of the natural rain-forest habitat. This is the first study to show that fruit bats are also able to assess the ripeness of a fruit exclusively by its odour. The bats preferred ripe over unripe fruits of the same species. Thus, both Pteropus pumilus and Ptenochirus jagori can not only locate fruits by their odour but can also discriminate between ripe and unripe fruits of the same species by olfaction. The results confirm and expand earlier findings on the role of olfactory cues in the orientation of foraging pteropodids.

Thalamic and cortical high-frequency (600 Hz) somatosensory-evoked potential (SEP) components are modulated by slight arousal changes in awake subjects.

Human somatosensory-evoked potentials (SEP) recorded at the scalp after conventional electrical median-nerve stimulation contain a low-amplitude (<500 nV), high-frequency (approximately 600 Hz) burst of repetitive wavelets, which are superimposed onto the primary cortical response N20. Previous electroencephalographic (EEG) studies have shown: (1) that these wavelets are generated near the hand area of the primary somatosensory cortex and in deep fibers of thalamocortical afferences; and (2) that only the 600-Hz burst, but not the N20 is decreased during sleep. Since the thalamus is involved in regulating both, selective attention and arousal, the present study aimed at characterizing the effects of focused attention and slight arousal changes on the 600-Hz oscillations. A dipole-source analysis of 64-channel SEP recordings after electric right-median-nerve stimulation allowed the comparison of brainstem, thalamic, and two cortical (one tangential, one radial) source activities in ten awake human subjects under two slightly different arousal states (eyes open vs. eyes closed), each tested for three conditions of focused attention (directed towards rare acoustic and right- or left-hand somatosensory target stimuli). While the N20 was not modified at all, the source strength of the high-frequency wavelet burst was significantly increased for eyes opened versus eyes closed, at the thalamic source site as well as for the tangentially oriented cortical source. In contrast, there were no significant differences between conditions with different attentional targets. This evidence for modulatory effects of increased arousal (eyes open) on both thalamic and cortically generated high-frequency SEP activity fits the hypothesis that the 600-Hz SEP burst at least partially represents an arousal-dependent signal generated at the thalamic level and transmitted to the primary somatosensory cortex.
