Characterization of the zebrafish gabra1 germline loss of function allele confirms a function for Gabra1 in motility and nervous system development.

Mutation of the GABRA1 gene is associated with neurodevelopmental defects and epilepsy. GABRA1 encodes for the α1 subunit of the γ-aminobutyric acid type A receptor (GABAR), which regulates the fast inhibitory impulses of the nervous system. Multiple model systems have been developed to understand the function of GABRA1, but these models have produced complex and, at times, incongruent data.

Stress, a Brief Update.

Stress is fundamental for health and adaptation; it is an evolutionarily conserved response that involves several systems in the organism. The study of the stress response could be traced back to the end of the nineteenth century with George Beard's or Claude Bernard's work and, from that moment on, several studies that have allowed the elucidation of its neurobiology and the consequences of suffering from it were consolidated. In this theoretical review, we discuss the most relevant researches to our knowledge on the study of stress response, from the concept of stress, its neurobiology, the hormonal response during stress, as well as its regulation, the effects of acute and chronic stress, stress from cognition, the different stress responses during life, as well as its relationship with different psychiatric disorders.

Conditional Generative Models for Dynamic Trajectory Generation and Urban Driving.

This work explores methodologies for dynamic trajectory generation for urban driving environments by utilizing coarse global plan representations. In contrast to state-of-the-art architectures for autonomous driving that often leverage lane-level high-definition (HD) maps, we focus on minimizing required map priors that are needed to navigate in dynamic environments that may change over time. To incorporate high-level instructions (i.

Probabilistic Semantic Mapping for Autonomous Driving in Urban Environments.

Statistical learning techniques and increased computational power have facilitated the development of self-driving car technology. However, a limiting factor has been the high expense of scaling and maintaining high-definition (HD) maps. These maps are a crucial backbone for many approaches to self-driving technology.

Treatment of Bolivian Leishmania braziliensis Cutaneous and Mucosal Leishmaniasis.

Although infection with Leishmania braziliensis is perhaps the key reason to treat New World cutaneous leishmaniasis (CL) and mucosal leishmaniasis (ML), the total literature contains relatively few reported cases. With the aim of supplementing the meager clinical information available, we searched the records of Jorochito (Dermatology) Hospital, Bolivia, for the years 1999-2020 and identified treatment records for 1,696 naive CL patients and 355 naive ML patients. Because follow-up was poor for this real-world treatment experience in the developing world, only 255 CL patients (15%) and 114 ML patients (32%) attended follow-up at Hospital.

Analysis of emissions-driven changes in the oxidation capacity of the atmosphere in Europe.

Anthropogenic emissions in Europe have been gradually reduced thanks to a combination of factors, including restrictive regulation and policy implementation, fuel switching, technological developments, and improved energy efficiencies. Many measures have been specifically introduced to meet the annual and hourly limit value of NO for the protection of human health, mainly targeting traffic emissions. Due to NO reduction policies in Europe, NO levels have generally declined, but O concentrations have been found to increase.
