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.

ABSTRACT The mouths and anuses of Penguins house complex microflora, which play important roles in growth and development. In this study, 6,391,065 sequences were detected from the oral and anal microflora of gentoo (Pygoscelis papua) penguins, with Firmicutes and Proteobacteria dominating the oral and anus samples from female gentoo penguins, respectively, while in males, Proteobacteria dominated the oral samples and Firmicutes dominated the anus samples. In addition, we provide the first demonstration that the dominant oral and anal microflora of P. papua (notably Firmicutes, Proteobacteria, Actinobacteria, and Bacteriodetes) exhibit a diel rhythm. Given that the status of penguin populations remains an issue of environmental and conservation concern, our work provides important insight into the health of this penguin species by focusing on the diversity, diel rhythms, and dynamics of dominant intestinal microflora, further offering useful reference materials for future studies on the diel interactions between microflora and the penguin host.

ABSTRACT The aim of the study is to validate the Polish version of the Single Item Chronotyping (SIC) tool, and thus confirm the relevance of Putilov’s six chronotypes. The SIC was used as an instrument intended to identify patterns of changes in alertness occurring throughout the day. The external validity of the SIC was confirmed by comparison to the Composite Scale of Morningness (CSM) scores, midsleep time on working days, midsleep time on free days and social jetlag. The sample consisted of 436 adult participants, with a mean age of 24.98 ± 8.41 (range 18 to 63). In a study sample, each SIC type was represented by at least 10% of participants. Differences were noted between SIC groups in a Composite Scale of Morningness. The relevance of Putlov’s chronotypology was confirmed for the Polish population. It may be possible to effectively measure chronotype with this single-item tool.

ABSTRACT Increasing evidences highlight the role of vasopressin (AVP) in the regulation of metabolic functions and the association between hydration state and metabolic disorders. Supraoptic nuclei (SON) neurons are particularly sensitive to metabolic changes, as shown by the loss of plasma AVP rhythmicity during diabetes. We aimed in this work to determine the effect of high energy (HE) feeding on SON clock functioning in Psammomys obesus, a desert herbivore rodent in which metabolic syndrome is nutritionally induced. Animals were subjected to either normal or HE feeding for 3 months. Immunohistochemical study indicates that AVP and the circadian transcription factor CLOCK profiles follow daily oscillations with higher content in the beginning of the rest period in control group fed with low energy (LE) diet. Our data show that HE feeding induces critical changes through impairment of daily AVP and CLOCK cycling in the SON. These findings show clearly that SON clockwork is altered by HE diet-induced metabolic changes. Further studies are needed to better understand SON neurons responses to metabolic derangement.

ABSTRACT Novel study on identification of critical heat stress zone (CHSZ) taking 20 years data was carried out in Indian buffaloes considering the effect of temperature humidity index-THI on milk production and composition traits. More than 3 lakh daily milk yield records (DMY); 9864 records each of monthly test day fat% (MTDF%) and SNF% (MTDSNF%) and meteorological data were collected from ICAR-NDRI and ICAR-CSSRI, Karnal, respectively. THI model [THI = (0.55× Tdb + 0.2× Tdp) × 1.8 + 32 + 17.5] by National Research Council in 1971 was used for computing THI. The year was classified into: Heat Stress Zone (HSZ) and Non-Heat Stress Zone (NHSZ) based on the trends of rising THI and declining milk production and composition traits. For DMY, NHSZ was 1st October to 9th April and HSZ was 10th April-30th September. For composition traits, October-March was NHSZ and April-September the HSZ. Within the HSZ regression analysis was conducted to find the zone where maximum drop in traits occur per unit rise in THI. A maximum decline in DMY 92.20 gram was observed during 15th August-14th September; identified as CHSZ for DMY. Similarly, maximum drop in MTDF% (b = −0.052) and MTDSNF% (b = −0.0114) observed during July-August, considered as CHSZ.

ABSTRACT Excessive or abusive use of smartphones, which is related to personality traits, has led to the emergence of phubbing, which is becoming a very widespread problem. Excessive use of smartphones also affects sleep patterns. In this context, the concept of chronotype, which is closely related to sleep, becomes prominent. Therefore, the present study aims to examine the relationship between chronotypes, personality traits, and phubbing levels of students studying in the field of health. 732 students participated in the study, which was planned using a correlational research design. Data were collected using a demographic form, the phubbing scale, the big five personality traits scale, and the composite scale of morningness (CSM). Descriptive statistical analyses, Pearson correlation analysis, and multiple linear regression analysis were used in the analysis of the data. As a result, Agreeableness, Conscientiousness, Neuroticism, and Morningness/Eveningness were significant predictors of phubbing. Other variables, on the other hand, were not found to be significant predictors of phubbing. Among the student participants in the study the phubbing level was high for those who were evening- and neither chronotype, who were not agreeable and conscientious, and who had neurotic personality traits.

ABSTRACT The daily pattern of total locomotor activity (TLA) of cattle kept in different housing conditions was investigated in order to evaluate whether TLA could be used as a useful index of animal welfare. Twenty Modicana cattle were divided into two equal groups: Group A, housed in a grazing area of 5 hectare, and Group B, housed in a paddock of 200 m2. Animals were equipped with activity-monitoring data loggers (Actiwatch-Mini®) to record the daily TLA for 7 days. The trigonometric statistical model, used to describe the rhythmic parameters (mesor, amplitude, acrophase and robustness of rhythm), indicated a diurnal rhythm of TLA in cattle. Animals belonging to Group B showed lower TLA, an anticipation of acrophase (time of activity peak) of TLA, and lower values of Mesor, amplitude and robustness of rhythm compared to Group A (p < 0.05). These results suggest that cattle in the paddock condition showed disturbed physiological characteristics of TLA displaying a flattening in its daily pattern compared to animals kept in the grazing area. This aspect should be taken into consideration of farming management in the planning of housing conditions, which should respect the requirement of locomotor activity and related physiological behaviors of cattle in order to guarantee the animal welfare.

ABSTRACT Membrane lipids play significant roles in cellular functions, including those controlled by circadian machinery (e.g., membrane transport). Membranes have been overlooked during the investigation of circadian mechanisms. The findings of previous studies suggest that membrane action potentials and phospholipid composition exhibit daily oscillations, which involve changes in fatty acid saturation and chain length, and are subjected to fatty chain remodeling. Thus, it is possible that membranes are affected by oscillatory output rhythms from cellular autonomous clocks. The regulation of lipid chain length and degree of unsaturation, along with resulting changes in membrane lipid polymorphic properties, may serve as the basis of an important mechanism that mediates the circadian regulation of various membrane-associated processes. However, direct evidence indicating that membrane lipid oscillations are part of the circadian machinery has yet to be reported. This review updates the current understanding of potential connections between the membrane bilayer and the circadian clock, with important implications for circadian rhythm disorders and related chronic diseases, such as obesity, diabetes, and cardiovascular disease.

ABSTRACT This study reports the copro-prevalence of giardiasis in sheep and cattle populations of nomadic communities in Multan-Pakistan. For this purpose, a total of 184 faecal samples were collected from cattle (n = 92) and sheep (n = 92) raised by the nomads. All samples were analyzed by using species-specific ELISA kits for the detection of copro-antigen of Giardia duodenalis. Results showed that the overall prevalence of giardiasis was 21.20%, whereas, in sheep and cattle, the prevalence rates were 19.18% and 23.91%, respectively. Age, clinico-physical status and drinking water source showed significant association (P < 0.05) with giardiasis in both sheep and cattle. Breed, history of gastrointestinal problems and routine vaccination were also significant (P < 0.05) risk factors in sheep but not in cattle. Deworming history had a significant association (P < 0.05) with giardiasis in cattle population only. Conversely, sex, herd size, farmers’ educational status, feeding pattern, physiological status, contact with wildlife and Giardia-susceptible animals and hygienic condition of housing facility showed non-significant association (P > 0.05) with giardiasis. In conclusion, the cattle and sheep raised by the nomads are infected with giardiasis and may pose a serious threat to susceptible animal and human populations in their surrounding regions.

ABSTRACT While sleepiness assessment metrics were initially developed in medical research, subjective sleepiness assessment is now widely used in both fundamental and applied studies. The Stanford Sleepiness Scale (SSS) and the Karolinska Sleepiness Scale (KSS) are often considered the gold standard in sleepiness research. However, their convergence and specific features have not been sufficiently investigated. The present study aims to analyse the dynamics and convergence of subjective sleepiness as measured by the KSS and SSS. A total of 208 adults participated in the experiment. Our findings suggest that sleepiness generally increased from the evening till night and was highest early in the morning. The SSS score appeared to be more sensitive to certain factors. The SSS and KSS scores strongly correlated with each other and converged on sleepiness assessment. However, the KSS showed a more even distribution of scores than the SSS. Currently, we are continuously expanding the SSDD.
