Influence of handling and conditioning protocol on learning and memory of Microplitis croceipes

Microplitis croceipes (Cresson) (Hymenoptera: Braconidae) learns odors in association with both hosts and food. The food‐associated ‘seeking’ behavior of M. croceipes was investigated under various training protocols utilizing the conditioning odor, 3‐octanone. We investigated the effects of odor training, or its lack, training duration, training frequency, time elapsed after training, wasp hunger state, and training reinforcement, on the food‐seeking responses of M. croceipes females. We found that odor‐trained females show strong food seeking responses, whereas non‐odor‐trained females do not respond to the odor, and that a single 10 s association with the odor whilst feeding on sugar water subsequently conditioned the wasps to exhibiting significant responses to it. Increases in training time to more than 10 s did not improve their responses. Repetition of the food–odor associations increased a wasp's recall, as well as its response over time, compared to a single exposure. Repeated exposure to the learned odor in the absence of a food reward decreased the responses of less hungry individuals. However, the level of response increased significantly following a single reinforcement with the food–odor association. Understanding the factors that influence learning in parasitoids can enhance our ability to predict their foraging behavior, and opens up avenues for the development of effective biological detectors.     

Preliminary results from the self-regulatory treatment of high-medication-consumption headache

Data are presented from a prospective clinical replication series of ten consecutive high-medication headache patients who presented for nondrug treatment of their headaches. For the first eight, an attempt was made to withdraw the patients from medication, with the assistance of relaxation training, prior to entering a comprehensive self-regulatory treatment program. For the last two, drug withdrawal accompanied the treatment. Six of the ten patients showed clinically significant reductions in headache activity, which held up over follow-ups of up to 12 months. Psychological tests provide some discrimination between success and failures.This research was supported in part by a grant from NINDS, No. NS-23340. Appreciation is expressed to Dr. Kenneth A. Appelbaum and Ms. Denise Michultka for their roles in this study.     

Effects of training on axial muscle of two cyprinid species: Chondrostoma nasus (L.) and Leuciscus cephalus (L.)

The effect of an endurance training program lasting 17 weeks was studied in two cyprinid species, Chondrostoma nasus (L.) and Leuciscus cephalus (L.). Red, intermediate and white axial muscle were investigated. Morphometrical analysis revealed that training induced, in both species, increased red and intermediate muscle mass, fibre diameter and capillarization. Differences between species in the response to training were observed for volume densities of mitochondria and lipid. In contrast to C. nasus, L. cephalus show higher values for these compartments in red and intermediate fibres. The results are considered adaptational changes which increase the aerobic capacity of red and intermediate muscle fibres to meet higher sustained swimming activities.     

Características de los programas de entrenamiento de fuerza muscular en personas mayores con sarcopenia. Revisión de alcance

ObjectiveThe aim of this scoping review was to analyze the resistance training-based programs’ characteristics and outcomes of physical and psychological health and cognitive functions measured in older adults with sarcopenia.MethodThis scoping review was carried out following the criteria and flow diagram established in the PRISMA guidelines and included studies from 2011 until 2020 from electronic databases, including PubMed, Scopus, and Web of Science.ResultsA total of 13 randomized controlled trials were included. The sample's average age was 72.2 years, with an age range between 71 and 80 years, considering a total sample of 1029 older adults (57% women). Resistance training-based programs were carried out mainly in university facilities, presented high adherence (91.2%) and were able to induce increase in strength and muscle mass. The most frequent parameters used were 2-3 weekly, 50-90-min-long sessions for 3-9 months, using between 8 and 15 repetitions, in an intense training zone with 1-RM between 60% and 85%. The most measured physical health outcomes were muscle strength, muscle mass, and BMI. Cognitive impairment was frequently evaluated, and few studies evaluated mental health.ConclusionThis review characterized resistance training-based programs in older people with sarcopenia, highlighting the extension, frequency, duration, and intensity of these, as well the most frequently used outcome measures and instruments. These results could be useful for prescribing future resistance training-based programs in older adults with sarcopenia.
