Abstract

The ventrolateral prefrontal cortex (VLPFC) shows robust activation during the perception of faces and voices. However, little is known about what categorical features of social stimuli drive neural activity in this region. Since perception of identity and expression are critical social functions, we examined whether neural responses to naturalistic stimuli were driven by these two categorical features in the prefrontal cortex. We recorded single neurons in the VLPFC, while two male rhesus macaques (Macaca mulatta) viewed short audiovisual videos of unfamiliar conspecifics making expressions of aggressive, affiliative, and neutral valence. Of the 285 neurons responsive to the audiovisual stimuli, 111 neurons had a main effect (two-way ANOVA) of identity, expression, or their interaction in their stimulus-related firing rates; however, decoding of expression and identity using single-unit firing rates rendered poor accuracy. Interestingly, when decoding from pseudo-populations of recorded neurons, the accuracy for both expression and identity increased with population size, suggesting that the population transmitted information relevant to both variables. Principal components analysis of mean population activity across time revealed that population responses to the same identity followed similar trajectories in the response space, facilitating segregation from other identities. Our results suggest that identity is a critical feature of social stimuli that dictates the structure of population activity in the VLPFC, during the perception of vocalizations and their corresponding facial expressions. These findings enhance our understanding of the role of the VLPFC in social behavior. [ABSTRACT FROM AUTHOR]

Abstract

Brazil is the fourth largest swine producer and pork exporter in the world, the slaughter under the federal meat inspection service achieved 37 million pigs in 2017 (https://sidra.ibge.gov.br). Brazilian meat inspection system is under a modernization process and new procedures are just standardized and regulated for pigs reared in farms submitted to health animal service rules. In order to supply the risk analysis for meat inspection modernization, several studies on zoonotic hazards were conducted in Brazil last years. This one was focused on zoonotic parasitosis once that in sanitary post mortem examination, the inspectors can identify lesions compatible with cysticercosis (Satyaprakash et al., 2018), hydatidosis (De La Rue, 2008) and sarcosporidiosis (Zainalabidin, et al., 2017). Cysticercosis is caused by metacestodes of Taenia solium. Primarily, cysticercosis is an infection of pigs that act as an intermediate host of T. solium. Pigs are infected by ingestion of contaminated water, soil or feed with the eggs of Taenia solium expelled from tapeworm carriers. The eggs develop into cysticerci in various organs and musculature causing porcine cysticercosis characterized by small round whitish viscous cyst (7 to 15 mm), located mainly in the lingual muscles, masseters, heart and diaphragm (Satyaprakash et al. 2018). Cystic echinococcosis is a zoonotic disease caused by the genus Echinococcus (Cestoda: Taeniidae). Pigs are considered important intermediate hosts of the larval stage by eggs ingestion from contaminated environment with feces of definitive host. The intermediated host develops hydatid cysts in the liver and the parasite cycle can be complete if a definitive host ingest this organ without a heat treatment (De La Rue, 2008). Sarcosporidiosis is a disease caused by cyst forming coccidian, namely, Sarcocystis spp. Pigs can be infected when consuming food contaminated with fecal material of carnivores containing the sporocysts of Sarcocystis spp. The whitish filamentous, spindleshaped, rice-grain-like, macrocyst-forming sarcocyst has been observed in the muscles of pigs, mainly in the heart, tongue and diaphragm (Zainalabidin, et al., 2017). The aim of this study was to validate the macroscopic diagnosis of these lesions detected by veterinary inspection service using histopathology analysis.

Abstract

The granulomatous lymphadenitis (GL) in pigs is mainly caused by Mycobacterium avium hominissuis (MAH), who belongs to the Mycobacterium avium Complex (MAC), considered non-tuberculous mycobacteria (NTM). Although GL does not affect swine zootecnical performance, economic losses occur during the slaughter line by condemning viscera and carcasses. The lesion is characterized by one or more foci of granuloma, which most frequently affect the organs of the digestive tract and peripheral lymph nodes. The main differential diagnosis encompasses Mycobacterium bovis (M. bovis) and Mycobacterium tuberculosis (M. tuberculosis), who belongs to the Mycobacterium tuberculosis Complex (MTbC), of relevant zoonotic potential. Nevertheless macroscopic examinations and histopathology are insufficient to determine the etiologic agent involved. Federal Meat Inspection had registered the frequency of 0,81 % of lymphadenitis in Brazil from 2012 to 2014. The aim of this study was to investigate the etiology of the granulomatous lesions for validation of the national data of inspection and build a database to further risk analysis.

Abstract

Acrisols, Ferralsols, Leptosols and Planosols were sampled in layers down to 1 m under dense caatinga, open caatinga, pasture and agriculture. Agricultural Leptosols and Planosols had the lowest C and N concentrations among the land uses, although in some cases differences were not statistically significant. On average, conversion of dense caatinga to agriculture reduced C stocks from63 to 47 Mg ha?1. Acrisols had the highest concentrations of C and N, and Planosols had the lowest concentrations and stocks. Conversion to pasture did not reduce stocks, but open caatinga also had lower C stocks (50 Mg ha?1) than dense caatinga. Nitrogen stocks did not differ among land uses, implying that losses are greater for C than for N. Despite the fact that the western portion of Pernambuco state covers 3% of the Brazilian semi-arid area, it stocks about 0.20 Pg of C (and 0.019 Pg of N), which represents 2% of the total estimated soil C stock in the semiarid region (8.9 Pg). Therefore, the stock per hectare in the west portion of Pernambuco is about one-third smaller than the stock per hectare in the whole Brazilian semiarid region, probably a consequence of the lower average C concentration in the 20 cm superficial layer, a higher proportion of agricultural fields and shallower depths of some soil classes inwestern Pernambuco than in the whole semiarid region.

Abstract

A 38 year-old woman, with orthostatic hypotension secondary to autonomic dysfunction accompanied by sympathetic hyperactivity and excess of dopamine, was treated with an antagonistic dopaminergic drug, metoclopramide, 30 mg/day, with good tolerance. Support intervention as well as the use of various drugs (beta-blockers, caffeine, fludrocortisone, haloperidol) showed no effect. The answer to metoclopramide both subjective and objective were remarkable. The way in which metoclopramide acts has not yet been fully clarified. Being a widely used drug, well tolerated, its use must be considered in cases of severe orthostatic hypotension, especially those with an excess of dopamine.
