ABSTRACT The relationship of sleep parameters and physical performances was assessed in young female handball players. Under 14 (13.44 ± 0.5 years), and under 17 (16.0 ± 0.8 years). Sleep patterns were evaluated using: Sleep quality (PSQI), insomnia (ISI) and sleepiness (ESS), questionnaires. Stork balance tests with open-eyes (OEB) and closed-eyes (CEB) were assessed. Squat-jump (SJ), standing broad jump (SBJ), five jump (FJT) and T-agility tests were determined. A positive correlation was found in U14 between the PSQI and ESS with agility time (r = 0.43 and 0.34, respectively), while a negative correlation was found between ISI and both: OEB (r = -0.48), and CEB (r = -0.38). For the U17, a negative correlation was found between ESS and CEB (r = -0.33). Results suggest that the quality of sleep related with age should be taken into consideration because it may affect balance and agility in young female handball players.

ABSTRACT The performance and productivity in poultry flocks are affected by climate change, especially in tropical islands. This study has been designed to understand the impact of two major seasons viz. summer (February-June) and rainy (July-September) on biochemical and immunological traits in three backyard poultry breeds viz. Desi (non-descript indigenous), Nicobari Fowl, and Vanaraja of Andaman and Nicobar Islands, India, for the first time. Ninety adult poultry birds were randomly selected from three different rural villages of the Andaman and Nicobar Islands including Desi (D, n = 30), Nicobari Fowl (NF, n = 30) and Vanaraja (V, n = 30). Ten birds each of D, NF and V from each village (sex ratio− 1:1) were chosen for the study. Serum samples collected (n=/bird/season/breed) from the three breeds were analysed. The study revealed that season had significant effect on biochemical parameters, i.e. serum albumin (p < 0.0001), globulin (p < 0.01), ALP (p < 0.05), total bilirubin (p < 0.05) and serum glutamic oxaloacetic transaminase (p < 0.05). Moreover, season had significant effect on immune parameters i.e. IL−2 (p < 0.0001), IL−4 (p < 0.0001), IL−6 (p < 0.0001&p < 0.05), HSP−70 (p < 0.0001&p < 0.01), TLR−4 (p < 0.01&p < 0.05) and INF-γ (p < 0.0001). It was observed that breed had significant effect on total bilirubin (D-V & NF-V, p < 0.0001), serum glutamic oxaloacetic transaminase (NF-V, p < 0.01 &D-V, p < 0.05). And also had significant effect on. IL−2 (D-NF, p < 0.001 &NF-V, p < 0.01), IL−4 (D-NF& D-V, p < 0.0001;NF-V, p < 0.05; D-V&NF-V, p < 0.01), IL−6 (D-NF & D-V, p < 0.0001), HSP−70 (D-NF & D-V, p < 0.0001; D-NF p < 0.01; NF-V, p < 0.05), and INF-γ (D-NF & D-V, p < 0.0001&D-NF, p < 0.05). This study could establish the seasonal influence on biochemical and immunological traits of rural backyard poultry breeds in tropical climate of Andaman and Nicobar Islands.
家禽的生产性能和生产力受到气候变化的影响，特别是在热带岛屿。本研究旨在首次了解夏季(2 - 6月)和雨季(7 - 9月)两个主要季节对印度安达曼和尼科巴群岛3个后院家禽品种德西(非描述土生)、尼科巴利家禽和瓦纳拉贾的生化和免疫性状的影响。选取安达曼-尼科巴群岛3个不同乡村的成年家禽90只，分别为Desi (D, n = 30)、Nicobari Fowl (NF, n = 30)和Vanaraja (V, n = 30)。每个村选取D、NF和V型各10只(性比为- 1:1)进行研究。对采集的3个品种(n=/鸟/季节/品种)血清样本进行分析。研究发现，季节对血清白蛋白(p < 0.0001)、球蛋白(p < 0.01)、碱性磷酸酶(p < 0.05)、总胆红素(p < 0.05)和谷草转氨酶(p < 0.05)等生化指标有显著影响。此外,季节对免疫参数即显著影响。IL 2 (p < 0.0001), IL−−4 (p < 0.0001), IL−6 (p < 0.0001 < 0.05),代替HSP 70−(p < 0.0001 < 0.01),代替TLR−4 (p < 0.01 < 0.05)代替和正-γ(p < 0.0001)。结果表明，品种对总胆红素(D-V、NF-V, p < 0.0001)、血清谷草酰乙酸转氨酶(NF-V, p < 0.01、D-V, p < 0.05)有显著影响。也对。IL−2 (D-NF p < 0.001 &NF-V, p < 0.01), IL−4 (D-NF& dv, p < 0.0001; NF-V p < 0.05;D-V&NF-V, p < 0.01), 6 (IL−D-NF & dv, p < 0.0001), HSP−70 (D-NF & dv, p < 0.0001;D-NF p < 0.01;NF-V, p < 0.05),正-γ(D-NF & dv p < 0.0001 &d-nf, p < 0.05)。本研究旨在了解安达曼和尼科巴群岛热带气候下农村散养家禽品种的季节生化和免疫特性。

ABSTRACT In the present study, accelerometer data obtained from a sensor prototype and data obtained from commercial animal-activity recording systems were recorded simultaneously and processed to identify the parameters most fully describing the locomotor activity of laboratory mice. A linear combination of the found parameters explained up to 66% of the variance of activity measured by the PhenoMaster system and up to 86% of the variance of activity measured by the LABORAS system, with 20-min averaging of the parameters measured every minute. Correlation coefficient between body temperature and activity measured by the prototype was higher than that for activity measured by the PhenoMaster system. It has been demonstrated that the developed sensor can be used to assess an animal’s locomotor activity at least with 20-min averages, and when powered by a 5 mAh battery with a total sensor weight of 0.9 g, the resulting runtime is expected to exceed 6 months effectively making it a data logger suitable for long-term field research.

ABSTRACT The aim of study was to identify the relationships between the circadian preference and diurnal training times of elite volleyball players (n = 78). The Morningness-Eveningness Questionnaire (MEQ) was used to identify circadian preference, resulting in a point score. Diurnal training times were divided: morning training time (MTT), intermediate training time (ITT) and evening training time (ETT). One-way ANOVA showed a relationship between circadian preference and diurnal training time documented by point score differences in the MEQ between MTT, ITT and ETT (p < 0.01). A higher (p < 0.01) point score value in the MEQ was recorded in the MTT compared to the ETT. No difference was found between MTT and ITT and ITT and ETT (p > 0.05). The results of the study show the importance of the relationship between circadian preference and typical training times during the day. The influence of training time on the development of circadian preference will need to be verified experimentally.

ABSTRACT The aim of the study was to evaluate the sleep, sunlight exposure, chronotype, mood and physical activity of college students in two consecutive years during the COVID-19 pandemic (Brazilian Clinical Trials Registry: RBR-4m5j4s). The students (n = 318) answered questionnaires in two moments (2020 - time 1 and 2021 – time 2). The data showed that there was less sunlight exposure and a chronotype with more morning tendencies in the time 2, but with no difference in sleep quality. College students walked more and sat less on weekends, but with no difference in the physical activity level. Physical activity and morning chronotype were associated with lower psychological impact. Therefore, college students, despite being less exposed to sunlight and having greater morning trends in 2021, maintained psychological symptoms, sleep quality and physical activity in the first two years of the pandemic. However, students who practiced physical activity and were mornings suffered less psychological impact.

ABSTRACT This study aimed to analyze the effect of Ramadan fasting (RF) on the morning-afternoon differences of cognitive and short-term maximal performances. . Fifteen young female handball players completed the attention (AT), simple reaction time (SRT), squat jump (SJ), Illinois agility (IAT) and 5-m shuttle run (5mSRT, to assess total (TD) and peak (PD) distances) tests at 08h00 and 1800 during ten days before Ramadan (BR), first ten days of Ramadan (F10R), last ten days of Ramadan (L10R) and ten days after Ramadan (AR). The results revealed that BR, SRT, AT, SJ, IA, TD and PD were greater in the afternoon compared to the morning (p<0.001). This morning-afternoon differences in physical and cognitive performances were reduced during F10R and were blunted or reversed during L10R (p<0.05). These findings suggest that the intraday differences in cognitive and physical performance in young female handball players might be blunted and/or reversed during RF.

ABSTRACT Environmental pollution is a threat to circadian rhythms of behaviour and physiology of organisms. The daily rhythm of swimming activity in zebrafish Danio rerio was studied to evaluate the toxicity of water from Lerma River, in Mexico, as it passed through the city of Salamanca, Guanajuato. Swimming activity along 3 days of acute exposure to polluted water, and then, the activity of the enzyme acetylcholinesterase and the oxidative stress in homogenized tissue was tested. Exposure to polluted water drastically reduces magnitude and alters the daily pattern of swimming activity. Cosinor analysis shows effect on mesor and robustness of rhythms, Tissue analysis showed a negative effect on AChE or an increase on oxidative stress. The analysis of water ions Al, P, F−, PO4 3-, SO4 2- in concentrations above the established in the official references. We discuss that daily swimming activity in zebra fish is useful to test water quality in polluted environments.

ABSTRACT 5-Fluorouracil (5-FU) is an antineoplastic drug. Although 5-FU is effective in targeting cancer cells, it also affects healthy cells, which can lead to clear haematological toxicity. The present study aimed to determine whether the haematological toxicity of 5-FU varies over a 24-hour period. Female rats were synchronised to a 12/12 light-dark (L/D) cycle. Rats were injected with 300 mg/kg 5-FU at six different circadian stages (1, 5, 9, 13, 17, 21 Zeitgebers (ZT)). The maximum rhythmic alteration was observed when 5-FU was administered at 5-ZT, while the minimum was observed at 21-ZT. These results suggest that the haematological toxicity of 5-FU is maximal when administered in the middle of the light-rest phase, while the haematological tolerance is optimal when 5-FU is administered at the end of the dark phase in rats, which corresponds to the end of the daytime activity phase in human patients.

ABSTRACT This study aimed to examine the nutritional status of healthcare professionals with different chronotypes and to determine their diet quality. Of the health care professionals (n = 204), 10.3% were morning chronotype (n = 21), 14.2% were evening chronotype (n = 29) and 75.5% were intermediate chronotype profiles (n = 154). Daily carbohydrate intake was significantly higher in the evening chronotype participants than was that in the morning and intermediate chronotype participants (p < 0.05). Daily intake of total fat, saturated fat, monounsaturated fatty acid (MUFA), and sodium in all the participants was above the population-specific recommended values, and saturated fat intake was highest in the evening chronotype participants. Nutritional status (except carbohydrate and potassium) and diet quality of healthcare professionals participating in the present study did not differ according to their chronotypes. Their diet quality was not good and their energy and nutrient intakes were below the requirements.
