in studying the temporal resolution of the visual system in general, and in studying inter-ocular differences or interactions in particular.The development of fast-acting antidepressants is crucial considering that conventional antidepressants require a long period to elicit therapeutic effects. Creatine, an ergogenic guanidine-like compound, stands out as a candidate to exert fast antidepressant-like responses. The present study investigated whether a single dose of creatine elicits a fast response in mice submitted to the novelty-suppressed feeding (NSF) test, a paradigm that may assess depression-like and anxiety-like behaviors. Ketamine, an NMDA receptor antagonist that has rapid antidepressant effects, and conventional antidepressants were also tested. The involvement of the mTORC1 signaling pathway in the behavioral responses was also investigated. Biochemical analyses included hippocampal BDNF level (ELISA) and total and phospho-mTORC1 (Ser2448), PSD95 and synapsin immunocontent (Western Blotting). Creatine (10 mg/kg, p.o.) or ketamine (1 mg/kg, i.p.) reduced the latency to feed in the NSF test. Conversely, fluoxetine (10 mg/kg, p.o.), imipramine (1 mg/kg, p.o.) or bupropion (10 mg/kg, p.o.) did not alter this parameter. The administration of rapamycin (mTOR inhibitor, 0.2 nmol/site, i.c.v.) abolished the effects of creatine or ketamine in the NSF test. Creatine or ketamine-treated mice presented increased hippocampal BDNF level, an effect abolished by rapamycin. Edralbrutinib inhibitor The hippocampal phospho-mTORC1 (Ser2448) immunocontent was increased by creatine, but not by ketamine. However, ketamine, but not creatine, increased PSD95 and synapsin immunocontent. Creatine and ketamine elicit a rapid response in the NSF test by a mechanism dependent on the mTORC1 signaling pathway.
To evaluate the prevalence of vitamin D deficiency in obese children and adolescents when compared to eutrophic controls.

Systematic review with meta-analysis covering studies with patients aged 0-18 years old diagnosed with obesity and vitamin D deficiency and control group of eutrophic patients. The studies were retrieved in the PubMed, Embase, and LILACS databases in December 2019. The search used the terms "obesity" in combination with "pediatric population" and "vitamin D".

Through the search 3155 articles were retrieved; and after analysis, 20 studies were selected according to the study objectives. A total of 24,600 children and adolescents were included. Through meta-analysis, the relative risk for the association between obesity and vitamin D deficiency in the pediatric population was 1.41 (95% CI 1.26-1.59) (I² = 89%, p < 0.01).

Children and adolescents with obesity have higher risk of vitamin D deficiency.

Although most studies of ancient genomes have focused on vertebrates, particularly archaic humans, newer technologies allow the capture of microbial pathogens and microbiomes from ancient and historical human and non-human remains. This coming of age has been made possible by techniques that allow the preferential capture and amplification of discrete genomes from a background of predominantly host and environmental DNA. There are now near-complete ancient genome sequences for three pathogens of considerable historical interest - pre-modern bubonic plague (Yersinia pestis), smallpox (Variola virus) and cholera (Vibrio cholerae) - and for three equally important endemic human disease agents - Mycobacterium tuberculosis (tuberculosis), Mycobacterium leprae (leprosy) and Treponema pallidum pallidum (syphilis). Genomic data from these pathogens have extended earlier work by paleopathologists. There have been efforts to sequence the genomes of additional ancient pathogens, with the potential to broaden our understanding of the infectious disease burden common to past populations from the Bronze Age to the early 20th century. In this review we describe the state-of-the-art of this rapidly developing field, highlight the contributions of ancient pathogen genomics to multidisciplinary endeavors and describe some of the limitations in resolving questions about the emergence and long-term evolution of pathogens.The study of bacteria interacting with their environment has historically centered on strategies for obtaining nutrients and resisting abiotic stresses. We argue this focus has deemphasized a third facet of bacterial life that is equally central to their existence namely, the threat to survival posed by antagonizing bacteria. The diversity and ubiquity of interbacterial antagonism pathways is becoming increasingly apparent, and the insidious manner by which interbacterial toxins disarm their targets emphasizes the highly evolved nature of these processes. Studies examining the role of antagonism in natural communities reveal it can serve many functions, from facilitating colonization of naïve habitats to maintaining bacterial community stability. The pervasiveness of antagonistic pathways is necessarily matched by an equally extensive array of defense strategies. These overlap with well characterized, central stress response pathways, highlighting the contribution of bacterial interactions to shaping cell physiology. In this review, we build the case for the ubiquity and importance of interbacterial antagonism.Like many organisms, bacteria and archaea have both innate and adaptive immune systems to defend against infection by viruses and other parasites. Innate immunity most commonly relies on the endonuclease-mediated cleavage of any incoming DNA that lacks a specific epigenetic modification, through a system known as restriction-modification. CRISPR-Cas-mediated adaptive immunity relies on the insertion of short DNA sequences from parasite genomes into CRISPR arrays on the host genome to provide sequence-specific protection. The discovery of each of these systems has revolutionised our ability to carry out genetic manipulations, and, as a consequence, the enzymes involved have been characterised in exquisite detail. In comparison, much less is known about the importance of these two arms of the defence for the ecology and evolution of prokaryotes and their parasites. Here, we review our current ecological and evolutionary understanding of these systems in isolation, and discuss the need to study how innate and adaptive immune responses are integrated when they coexist in the same cell.
