Monika Wipf, Corinne Bok-Beaube, Anja Palmowski-Wolfe
Cyclic strabismus is a rare disease of unknown origin. If untreated, it leads to manifest strabismus with the risk of amblyopia in children. Treatment is generally surgical. Here we report on three children in whom cyclic esotropia was successfully treated with one bimedial injection of 5 IU Botox ® . All patients remained orthotropic with good stereo functions at the last follow-ups at 16, 11, and 8 months. Botulinum toxin offered a minimally invasive treatment option in these patients.

OBJECTIVE: The option of performing MVD under awake anesthesia protocol ("awake" MVD) was examined in this initial series to assess whether intraoperative pain evaluation can identify and mitigate insufficient decompression of the trigeminal nerve, improving surgical outcomes. Additionally, "awake" MVD could expand procedure indications for those with comorbidities that would prohibit general endotracheal anesthesia (GEA). METHODS: An IRB-approved prospective study of 10 consecutive adults who underwent MVD for TN was conducted...

Sticholysin II (StII) is a pore-forming toxin of biomedical interest that belongs to the actinoporin protein family. Sticholysins are currently under examination as an active immunomodulating component of a vaccinal platform against tumoral cells and as a key element of a nucleic acids delivery system to cell cytosol. These proteins form pores in the plasma membrane leading to ion imbalance and cell lysis. However, the intracellular mechanisms triggered by actinoporins upon binding to membranes and its consequences for cell death are barely understood...

Conventionally, chitosans are derived from shrimp and other crustacean shells. Biotechnology offers an alternative route to produce chitosans and more importantly, specific chitosan structures tailored to the needs of a diversity of industries. However, for biotech chitosans and products thereof to be commercialised, legislation should not create a burden. Here, the requirements of the EU regulatory framework have been analysed for the entire chain from research to development and production of several potential applications including nanomaterials...

O Garaschuk, H M Semchyshyn, V I Lushchak
Brains' high energy expenditure with preferable utilization of glucose and ketone bodies, defines the specific features of its energy homeostasis. The extensive oxidative metabolism is accompanied by a concomitant generation of high amounts of reactive oxygen, nitrogen, and carbonyl species, which will be here collectively referred to as RONCS. Such metabolism in combination with high content of polyunsaturated fatty acids creates specific problems in maintaining brains' redox homeostasis. While the levels of products of interaction between RONCS and cellular components increase slowly during the first two trimesters of individuals' life, their increase is substantially accelerated towards the end of life...

The blood-oxygenation level dependent (BOLD) functional magnetic resonance imaging (fMRI) signal is commonly used to assess functional connectivity across brain regions, particularly in the resting state (rs-fMRI). However, the BOLD fMRI signal is not merely a representation of neural activity, but a combination of neural activity and vascular response. These aspects of the BOLD signal are easily influenced by systemic physiology, potentially biasing BOLD-based functional connectivity measurements. In this work, we focus on the following physiological modulators of the BOLD signal: cerebral blood flow (CBF), venous blood oxygenation, and cerebrovascular reactivity (CVR)...

The elytral base sclerites (= sclerites located at the articular region between the forewing and thorax in Coleoptera) of selected taxa were examined and homologized. Although the elytral base sclerites are highly modified compared to the wing base sclerites of the other neopterans, they can be homologized by using the conservative wing flapping and folding lines as landmarks. A reduction of the first axillary sclerite was identified as a general trend of the elytral base sclerites, although the sclerite usually has a very important function to mediate flight power from the notum to the wing...

BACKGROUND: Fear conditioning (FC) in rodents is the most used animal model to investigate the neurobiology of posttraumatic stress disorder (PTSD). Although research using FC has generated a better understanding of fear memories, studies often rely on mild or moderate FC training and behavioral analysis generally focuses on measuring freezing responses within few test sessions. NEW METHOD: We introduce the M-Maze task, a system to measures extinction of conditioned fear using suppression of operant behavior...

We propose a novel mathematical model for a metapopulation in which dispersal occurs on two levels: juvenile dispersal from the natal site is mandatory but it may take place either locally within the natal patch or globally between patches. Within each patch, individuals live in sites. Each site can be inhabited by at most one individual at a time and it may be of high or low quality. A disperser immigrates into a high-quality site whenever it obtains one, but it immigrates into a low-quality site only with a certain probability that depends on the time within the dispersal season...

Growth curve models play an instrumental role to quantify the growth of biological processes and have immense practical applications across disciplines. In the modelling approach, the absolute growth rate and relative growth rate (RGR) are two most commonly used measures of growth rates. RGR is empirically estimated by Fisher (1921) assuming exponential growth between two consecutive time points and remains invariant under any choice of the underlying growth model. In this article, we propose a new measure of RGR, called modified RGR, which is sensitive to the choice of underlying growth law...
