The adequate disposal of agricultural waste is one of the major concerns of public officials and a research challenge to obtain sustainable solutions to the problem. In this sense, the objective of this study was to evaluate the banana leaf stalk use as substrate in solid-state fermentation (SSF) for production of amylolytic and cellulolytic enzymes by Penicillium spp. LEMI A11 strain grown under different substrate concentrations, pH and temperature. Effects of different pH conditions (5.0 and 6.0), temperature (30 and 35 °C) and substrate concentration 70 and 90% (in relation to the final volume) of the fermentation were evaluated over 120 hours of fermentation. The results indicated that Penicillium spp. LEMI A11 was able to use the banana stalk as substrate under SSF. The maximum activities for amylase dextraining, amylase saccharifying and CMCase were 0.18; 0.13 and 04 U.g-1, respectively. The effect of environmental factors related to the substrate concentration was significant for saccharifying amylase and CMCase activity only. The interaction between the environmental factors tested was significant for the dextrinizing amylase activity only. It was verified enzyme activity reduction after 96 hours of fermentation for all enzymes. It concluded that banana stalk is an alternative carbon source to be used in SSF for enzyme production by of Penicillium spp. LEMI A11.

AbstractReductionist thinking in neuroscience is manifest in the widespread use of animal models of neuropsychiatric disorders. Broader investigations of diverse behaviors in non-model organisms and longer-term study of the mechanisms of plasticity will yield fundamental insights into the neurobiological, developmental, genetic, and environmental factors contributing to the “massively multifactorial system networks” which go awry in mental disorders.

Abstract The global prevalence of obesity has been rising at an alarming rate, accompanied by an increase in both childhood and maternal obesity. The concept of metabolic programming is highly topical, and in this context, describes a predisposition of offspring of obese mothers to the development of obesity independent of environmental factors. Research published in this issue of Clinical Science conducted by Litzenburger and colleagues (Clin. Sci. (Lond.) (2020) 134, 921–939) have identified sex-dependent differences in metabolic programming and identify putative signaling pathways involved in the differential phenotype of adipose tissue between males and females. Delineating the distinction between metabolically healthy and unhealthy obesity is a topic of emerging interest, and the precise nature of adipocytes are key to pathogenesis, independent of adipose tissue volume.

The World Health Organization's (WHO's) 2001 International Classification of Functioning Disability and Health (ICF) has as one of its central tenets the full inclusion of persons with disabilities in society. It acknowledges the need for medical and rehabilitation intervention in its biopscychosocial framework. However, the WHO realizes that society must do its part to facilitate this full participation and empowerment. Persons with complex communication needs (PWCCN) often need augmentative and alternative communication (AAC) in order to express themselves. However, in order to access and successfully use AAC, PWCCN need access to the necessary AAC devices and services, as well as a willing society to interact with them as full contributing members of society. The factors outside of a person's specific physical and/or cognitive functional limitations are addressed in the ICF via the Personal and Environmental Factors. Personal Factors include the individual's personality traits, lifestyle, experiences, social/educational/professional background, race, gender, and age. Environmental Factors include community support systems, social service agencies, governments, social networks, and those persons that interact with the PWCCN. This article addresses the sociopolitical influences on PWCCN and their functioning from a human rights perspective. The necessary introspective role of speech-language pathologists in this process is explored.
