No full textThe cytoarchitecture of the adult human parabrachial nucleus: a Nissl and Golgi study
No full textThe parabrachial nucleus (PBN) plays important roles in numerous autonomic functions and in pain modulation. In different animal species, three main regions of the PBN have been identified: the m-PB, the 1-PB, and the Kölliker-Fuse nucleus (KF). The KF has not been identified in humans. The present study used Nissl and Golgi-Cox material and morphoquantitative methods to investigate the cytoarchitectural organization of the adult human PBN, paying particular attention to neuronal features endowed with functional significance, i.e. the arborization of the neurons. The PBN neuron population is made up of elements which are heterogeneous in size, shape and dendritic arborization, and grouped into two regions, the lateral and medial PBN (1- and m-PB). It has been suggested that some large sized neurons located in the ventral region of the m-PB might be the counterpart of the KF. In the m-PB the fusiform neurons are the most numerous cells; in the 1-PB the multipolar neurons prevail, and are particularly numerous in the dorsal 1-PB. Since the dendritic arborization is generally the main target of afferent projections to a neuron, it is possible that the 1-PB, and in particular its dorsal region, might be the main site for the endings of afferences to the human PBN

No full textArsenic ranks among the priority metals that are of public health significance. In the environment, the metalloid arsenic mainly exists under two forms: the arsenite [As(III)] and arsenate [As(V)]; the former being more toxic due to its high mobility and stability. Bacteria have developed multiple strategies for arsenic detoxification.
Rhodococcus aetherivorans BCP1 is able to cometabolize chlorinated compounds, mineralize a wide range of hydrocarbons1, resist different stress conditions2 and convert tellurite and selenite into less toxic forms3, making this strain an ideal candidate for microbial biotechnology applications. In this study, we assessed the ability of BCP1 to tolerate high concentrations of As(V) during its growth under aerobic conditions. Furthermore, different aspects regarding the arsenic homeostasis and the response of BCP1 to As(V) were investigated: (i) the different capability to convert As(V) into As(III) depending on the initial concentration of arsenate; (ii) the arsenic biosorption; (iii) the effect of arsenic on polyphosphate granule formation and (iv) the genetic/genomic aspects involved in arsenic detoxification. Finally, the detection of electrondense nanoparticles after the incubation with As(V) suggested the ability of BCP1 strain to generate As-based nanostructures
