Effects of daytime exposure to different monochromatic lights on the excretion of 6-sulfatoxymelatonin (aMT6s) in a hospital environment Biol. Rhythm Res. (IF 0.826) Pub Date : 2021-01-03 Teresinha Guerreiro Cervi Angstmam; Ayrton Custodio Moreira; Edson Zangiacomi Martinez
ABSTRACT Hospitalized patients are frequently deprived of contact with natural light and constantly exposed to artificial lighting, losing biological synchronism. However, few studies have been conducted to assess the consequences of inadequate exposure to light in hospital environments, whether related to insufficient light in the period daytime, or to light peaks at night. This study assesses the

Effects of exposures to weak 2-Hz vs. 8-Hz electromagnetic fields on spectral characteristics of the electroencephalogram in afternoon nap Biol. Rhythm Res. (IF 0.826) Pub Date : 2020-12-20 Vladimir B. Dorokhov; Anton O. Taranov; Dmitry S. Sakharov; Svetlana S. Gruzdeva; Olga N. Tkachenko; Gleb N. Arsenyev; Natalya V. Ligun; Dmitry S. Sveshnikov; Zarina B. Bakaeva; Valeriy V. Dementienko; Alexandra N. Puchkova
ABSTRACT The human brain seems to be able to respond to low-level extremely low-frequency electromagnetic fields. Controlled laboratory studies of human sleep under exposure to such fields are scarce, especially on the effects of 1 Hz – 16 Hz fields overlapping with the frequencies of the electroencephalographic (EEG) signal (e.g., delta, theta, alpha, and sigma activities). In a double-blind placebo-controlled

The effects of ovariectomy on the behavioral and physiological responses to constant light in C57BL6/J Mice Biol. Rhythm Res. (IF 0.826) Pub Date : 2020-12-01 Julie M. Michaud; John C. Price; Hannah V. Deane; Holly A. Concepcion; Jason A. Coronella; Holly DeCourcey; Joseph A. Seggio
ABSTRACT Circadian disruptions, including exposure to constant light, are known to produce behavioral and physiological issues. However, sex differences exist in how those problems manifest, as males tend to have increased susceptibility to the negative consequences of circadian disruption. As gonadal hormones play a role in circadian timekeeping, we decided to investigate whether ovariectomized C57BL6/J

Assessment of time window for sleep onset on the basis of continuous wrist temperature measurement Biol. Rhythm Res. (IF 0.826) Pub Date : 2020-07-29 Timo Partonen; Jari Haukka; Liisa Kuula; Anu-Katriina Pesonen
The interactions of the principal circadian clock with the homeostatic sleep process create the time-sensitive window for easy falling asleep in the evening, which is affected by a thermoregulatory process. It has been hypothesized that the changes in skin and core body temperatures before the sleep onset might play a direct role in sleep regulation. To determine this time window, we recorded from

‘Ramadan’ is observed by the Muslims around the world, out of their religious belief, as a period when they fast all day and break fasting only after sun set. The Ramadan fasting, which can be viewed as alternate fasting owing to the nature of food intake during this time, stretches for 28 days. The food intake prior to sun rise is known as ‘sahour’ and that after sunset is called ‘iftar’. In view

Role of environmental stressor-host immune system–pathogen interactions in development of infectious disease in farm animals Biol. Rhythm Res. (IF 0.826) Pub Date : 2019-11-27 Sophia Inbaraj; Veerasamy Sejian; Santhamani Ramasamy
Animal husbandry serves as a source of provision of high-quality animal protein to the entire world population. Farm animals are exposed to different types of stressors at various stages of their life cycle. The climate change phenomenon also imposes additional stress on the animals due to extreme temperature (heat and cold) and unavailability of feed, etc. Such stress stimuli induce the release of

Northeast Brazilian donkeys have little physiological responses influenced by tropical conditions Biol. Rhythm Res. (IF 0.826) Pub Date : 2019-11-25 Ariana Lopes Correia de Paiva; Josiel Ferreira; Talyta Lins Nunes; Andressa Nunes Mouta; Naftali Silva Fernandes; Jerson Marques Cavalcante; Raimundo Alves Barrêto Júnior; Valéria Veras de Paula
Ten northeast Brazilian donkeys were used to evaluate the influence of meteorological variables on their physiological responses in tropical conditions. Physiological data included respiratory rate (RR), heart rate (HR), rectal temperature (RT), systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP) and cortisol concentrations. The environment was characterized

Performance of crossbred goat kids fed with diets varying in concentrate-to-forage ratio: intake, nutrient utilization, enteric methane emission and body weight changes Biol. Rhythm Res. (IF 0.826) Pub Date : 2019-11-25 Shubham Thakur; Madhu Mohini; Tariq A. Malik; Sanjay Howal; Tarun Kumar Varun; Anubha Madavi; Ram Dev Yadev; Goutam Mondal; Chander Datt
The present study was undertaken to evaluate the effect of isonitrogenous diets varying in concentrate-to-forage ratio on enteric methane (CH4) emission, nutrient utilization and growth performance in crossbred goat kids. Fifteen Alpine and Beetal crossbred (AxB) kids (3–4 months age) were divided into three groups based on average body weight and treatments were assigned to the three groups randomly

Impact of environmental and incubation factors on hatchability of duck eggs Biol. Rhythm Res. (IF 0.826) Pub Date : 2019-11-22 Mohamed E. Abd El-Hack; Cesar Betancur Hurtado; Dairon Más Toro; Mahmoud Alagawany; Essam M. Abdelfattah; Shaaban S. Elnesr
Hatchability is the most important elements for producing more ducks. Hatchability is an indicator used to determine the economic value for any commercial hatchery. Optimal conditions during the incubation process may be defined as those leading to maximum hatchability of healthy ducklings. One of the main factors in the success of the duck hatching process is to adjust the appropriate temperature

Seasonal influence of age at first calving on genetic variation and subsequent reproductive performances in Murrah buffaloes Biol. Rhythm Res. (IF 0.826) Pub Date : 2019-11-22 Ranjeet Verma; Kennady Vijayalakshmy; Meenakshi Virmani; Sanjeev Kumar; Ashutosh Verma
The age at first calving (AFC) has a huge impact on profitability in the dairy industry. It can be used as an indicator of fertility and productivity and it is also considered as an essential factor to ascertain the overall production performance of the animal. There are large variations in AFC in herd to herd, breed to breed and also country to country. This may be due to various factors that affect

The present study surveyed that the prevalence of subclinical and clinical ketosis in cattle was assessed in and around Bikaner; a total of 200 cows after parturition were examined. The overall prevalence of clinical ketosis amongst post-parturient cows was 11.50%, while 23.50% for subclinical ketosis. Prevalence of clinical and subclinical ketosis in cows with relation to breed was the highest in
