Role of autophagy during methamphetamine neurotoxicity
No full textMethamphetamine causes nigrostriatal denervation and striatal dopamine loss, while sparing nigral cell bodies. Nigral dopamine neurons feature autophagic vacuoles and cytoplasmic alpha-synuclein-, ubiquitin- and parkin-positive inclusion-like bodies. On that basis, autophagy was considered essential in methamphetamine-induced neurotoxicity, but its neurotoxic or protective role has never been addressed. Here we review the gap between the descriptive evidence on activation of autophagy and the lack of knowledge about its role during methamphetamine intoxication. Our preliminary findings rule out a detrimental role for autophagy; this represents the first step in understanding the consequence of activation of autophagy in methamphetamine toxicity

Generation of 22-mJ, 2.0-ps Pulses from a 1-kHz Ho:YLF Regenerative Chirped Pulse Amplifier
No full textWe report a CW-pumped Ho:YLF regenerative amplifier (RA) delivering pulses with 22.5-mJ energy and 2.0-ps duration at 1 kHz. The RA emitting at 2051 nm is broadband-seeded and implemented in a chirped pulse amplification system. © 2024 The Author(s
Benzodiazepine receptors: localization in rat amygdala
No full textBehavioral, electroencephalographic, and evoked potential studies, as well as experiments utilizing the direct intracerebral injection of benzodiazepines (BZs), have implicated the amygdala, particularly its basolateral nuclear division, as an important locus of the therapeutic actions of these drugs. BZ receptor localization within the amygdala could further define which amygdaloid nuclei are important for BZ action and suggest neuroanatomical pathways especially sensitive to these drugs. Using a quantitative light microscopic autoradiographic technique, this study has localized type 1 and type 2 BZ receptors within the amygdaloid nuclear complex of the rat. BZ receptors were labeled with [3H]flunitrazepam, and type 1 BZ receptor binding was preferentially displaced by CL218,872 in 8-micron coronal sections of rat brain. Autoradiograms were generated by the apposition of emulsion- coated coverslips and quantified by standardized procedures. Ten amygdaloid nuclei were examined at nine levels over the rostrocaudal extent of the amygdala. Total BZ receptor density was highest in the basolateral nuclear complex, and the majority of these receptors were of the type 2 subclass. Type 1 receptors were concentrated in the anterior aspects of the amygdala, particularly the anterior cortical nucleus. These results are consistent with an important role for the basolateral amygdala in anxiogenesis and seizure induction. Furthermore, a larger circuit which includes the amygdala, ventromedial hypothalamus, mammillary body, anterior thalamus, and frontal cortex could be involved in the anxiolytic actions of the BZ drugs.</jats:p
Pure-rotational 1D-CARS spatiotemporal thermometry with a single regenerative amplifier system
No full textWe report spatiotemporal pure-rotational coherent anti-Stokes Raman spectroscopy (CARS) in a one-dimensional imaging arrangement obtained with a single ultrafast regenerative amplifier system. The femtosecond pump/Stokes photon pairs, used for impulsive excitation, are delivered by an external compressor operating on a ∼35% beam split of the uncompressed amplifier output (2.5 mJ/pulse). The picosecond 1.2 mJ probe pulse is produced via the second-harmonic bandwidth compression (SHBC) of the ∼65% remainder of the amplifier output (4.5 mJ/pulse), which originates from the internal compressor. The two pump/Stokes and probe pulses are spatially, temporally, and repetition-wise correlated at the measurement, and the signal generation plane is relayed by a wide-field coherent imaging spectrometer onto the detector plane, which is refreshed at the same repetition rate as the ultrafast regenerative amplifier system. We demonstrate 1 kHz cinematographic 1D-CARS gas-phase thermometry across an unstable premixed methane/air flame-front, achieved with a single-shot precision <1% and accuracy <3%, 1.4 mm field of view, and an excellent <20 µm line-spread function.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Flight Performance and Propulsio
Project: Establishing an accounting outsourcing company "MJ Grāmatvedība" Ltd
No full textProjekta ideja ir izveidot grāmatvedības ārpakalpojumu uzņēmumu SIA „MJ Grāmatvedība”, kurš sniegtu pilna vai daļēja cikla grāmatvedības pakalpojumus, sākot ar pirmreizējo dokumentu apstrādi un beidzot ar visu nepieciešamo atskaišu sagatavošanu, kā arī konsultāciju sniegšanu. Projekta mērķis ir ne tikai sniegt grāmatvedības pakalpojumus, bet arī analizēt uzņēmumu darbību un izstrādāt ieteikumus darbības uzlabošanai. Darba autore uzskata, ka nozares pārstāvjiem ir būtiski jāpierāda sava nozīme un to kādam jābūt mūsdienu grāmatvedim. Grāmatvedis nav tikai persona, kura izdara konkrētus darbus, nodos atskaites, tas ir cilvēks, kuram labi jāpārzina nodokļu sistēma, finanšu vadīšana, jāspēj sniegt padomus uzņēmuma finanšu vadības uzlabošanai, kā arī jāspēj pielāgoties tehnoloģiju radītajām izmaiņām. Maģistra darbs apjoms ir uz 105 lappusēm, kas sastāv no 7 nodaļām, 17 pielikumiem, 22 tabulām un 7 attēliem. Darba izstrādē izmantoti 70 informācijas avoti.The general project idea is to establish the accountancy firm MJ Accountancy Ltd., which would provide full or half-cycle accountancy services including the processing of primary documentation, reports’ preparation, and providing of the accountancy consultations. The aim of the project is not only to provide accountancy consultations but also to deal with firms activity analysis and developing suggestions on their activity improvement. The author of the project supports the idea that the field representatives must constantly sustain the status of the accountant’s profession in current times. The accountant is not only the person who executes one’s regular duties and submits reports, but also the person who is competent in the field of taxes, financial management, able to advise on improvements in financial management, and above all able to adapt to the technological changes. The volume of the project is 105 pages, which includes 7 chapters, 17 appendices, 22 tables, 7 figures. 70 sources of information were used in master’s thesis
