Branched Chains

During late summer 1996 to 1997, 27 to 30% of Gypsophila paniculata (baby's-breath) plants were noted as diseased in an experimental field (Kazanlak, Bulgaria). Symptoms on lower and middle leaves consisted of small circular spots, with light brown centers and reddish purple margins. Development of numerous spots (which grew larger) and, especially, damage to the midrib led to withering of leaflets. Conidiophores of the isolated fungus were dark, formed singly or in clusters, were unbranched with three to eight septa, and were 40 to 120 µm long. Conidia, produced in branched chains (four to six conidia or longer), were brown, globose, and ovate to pyriform with short beaks, contained four to five transverse and zero to two longitudinal septa, and were 36.6 to 46.6 × 10.0 to 13.3 µm. The fungus was identified as Alternaria alternata. Pathogenicity was confirmed by artificial inoculation of potted G. paniculata and Dianthus caryophyllus plants. Conidia (2 weeks old) produced on potato dextrose agar were sprayed on plants in a 5 × 103 suspension, and plants were incubated at 20 to 24°C in a moist chamber for 2 days. Lesion development in both plant species was observed and recorded at 4 to 5 and 6 to 7 days after inoculation, respectively. Lesions were most numerous on G. paniculata. This is the first report of A. alternata on baby's-breath in Bulgaria. References: (1) M. B. Ellis. 1971. Dematiaceous Hyphomycetes. Commonwealth Mycological Institute, Kew, U.K. (2) E. G. Simmons.

Mechanisms Of Plasticity

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.

Full Participation

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.
