AIM: To define NGF (nerve growth factor) and its high- affinity receptor trkANGF presence and distribution in fibrotic liver and in HCC, and to verify if NGF might have a role in fibrosis and HCC. METHODS: Intracellular distribution of NGF and trkANGF were assessed by immunohistochemistry and immuno- electron microscopy in liver specimens from HCC, cirrhosis or both. ELISA was used to measure circulating NGF levels. RESULTS: NGF and trkANGF were highly expressed in HCC tissue, mainly localized in hepatocytes, endothelial and some Kupffer cells. In the cirrhotic part of the liver they were also markedly expressed in bile ducts epithelial and spindle-shaped cells. Surprisingly, in cirrhotic tissue from patients without HCC, both NGF and trkANGF were negative. NGF serum levels in cirrhotic and/or HCC patient were up to 25-fold higher than in controls. CONCLUSION: NGF was only detected in liver tissue with HCC present. Intracellular distribution suggests paracrine and autocrine mechanisms of action. Better definition of mechanisms may allow for therapeutic and diagnostic/prognostic use of NGF.

On the Range of Action of Adult Culex pipiens s.l.

Mosquitoes are an interesting topic due to their medical importance, as they play an active role in the transmission of many pathogens and parasites, acting as vectors for various pathologies that are deadly to humans, such as dengue, yellow fever, chikungunya, West Nile virus, encephalitis and malaria, among many others that are less common. In terms of morbidity and mortality caused by vector-borne diseases, mosquitoes are the most dangerous animals for humanity and, although they also play a role in the ecosystem as a food source for other organisms, their importance for public health cannot be overlooked. As highly efficient vectors, they put more than three billion people at risk, mainly in tropical and subtropical regions as well as in Europe, since heat waves and flooding are becoming more frequent and severe, and summers are getting longer and warmer, accelerating mosquito development, biting rates, and the incubation of the pathogens within their bodies. Female mosquitoes bite to acquire proteins for the development of their ovaries and eggs and, in the process, acquire pathogens and/or parasites from one vertebrate host and transmit them to another, usually after a short period of replication. Three of their four life stages are lived in still freshwater, so it is crucial to understand their range of action when they reach adulthood and leave the water, in order to plan and implement local prevention measures. A set of georeferenced abundance data collected in mainland Portugal over seven years was linked to cartographed water bodies in a geographic information system to estimate the distances at which Culex pipiens s.l. had a significant presence, with criteria based on the size of the catches. The result allows for an estimate of the fly range of those mosquitoes, which can be used to focus countermeasures.

A Comparison of Airborne Formaldehyde Field Measurements Collected in an Anatomic Pathology Laboratory

Environmental monitoring of airborne formaldehyde (FA) using sensitive methodologies is fundamental to prevent health risks. The objective of this study was to compare three different FA monitoring methods during the daily activities of an anatomic pathology laboratory. Daily eight-hour measurements deriving from Radiello® passive diffusive samplers (PDS), NEMo XT continuous optical sensor (COS), and multi-gas 1512 photoacoustic monitor (MPM) were simultaneously compared over a period of 14 working days. Given the different daily distributions of the measurements performed by the three devices, all measurements were time-aligned for comparison purposes. The 95% limit of agreement (LOA) method was applied to estimate the degree of concordance of each device with respect to the others. Formaldehyde arithmetic mean measured using PDS was 32.6 ± 10.4 ppb (range: 19.8 - 62.7). The simultaneous measures performed by COS and MPM were respectively 42.4 ± 44.8 ppb (range: 7.0 - 175.0) and 189.0 ± 163.7 ppb (range: 40.0 - 2895.4). The MPM geometric mean (171.3 ppb) was approximately five times higher than those derived from COS (32.3 ppb) and PDS (31.4 ppb). The results of the LOA method applied to log-transformed FA data showed the same systematic discrepancies between MPM and the other two devices. A good agreement between PDS and COS could lead to a tailored approach according to the individual specificity of these techniques. This tool may be useful for accurately assessing the risk of FA exposure among healthcare workers. However, the limited specificity of the MPM does not support its use as a monitoring method for FA in the workplace.

The plasticity of plasticity:lesson from remote microglia induced by focal central nervous system injury

Neural Regeneration Research 2020年第1期15卷 57-58页

作者： maria teresa Viscomi Institute of Histology and Embriology Università Cattolica del S.Cuore

The last decades have represented an important season in the re-conceptualization of brain plasticity,especially in extending the concept at events occurring beyond the developmental stage and in demonstrating the profound impact of these changes on so-called spontaneous recovery after central nervous system(CNS)*** study of the cellular,molecular,functional and structural mechanisms involved in brain plasticity has clearly emphasized the multitude of players engaged in this phenomenon,leading to the conceptualization that non-neuronal cells and non-neuronal mechanisms intervene in these changes and orchestrate some of the responses observed(Werner and Stevens,2015).Among the different non-neuronal cells and non-neuronal substrates of injury-induced plasticity is becoming increasingly recognized that microglia drive a series of intrinsic CNS responses after damage(Sandvig et al.,2018;Bisicchia et al.,2019).

Since their first description in the brains of patients suffering from Alzheimer ’s disease(AD), more than 100 years ago, extracellular amyloid-β(Aβ) plaques and intracellular neurofibrillary tangles have been the principal focus of AD research. However, this focus has led to the failure of several long and promising clinical trials, and the efficacy of new Aβ-targeting drugs to slow down the disease progression is still controversial despite being successful in reducing the Aβ load.
