Our study aimed to obtain data on the age and individual characteristics of the glands of the vaginal vestibule in postnatal human ontogenesis. Material and research methods. By the macromicroscopic way, the small glands of the vaginal vestibule wall were investigated in cadavers of 163 women of different ages without pathology of the urogenital system. The total number, length, width, density of location, the area of the initial section, the diameter of the common excretory duct of the glands, the number of glands with ampoule-widened excretory ducts, and glands were determined. The results of the study. The conducted macromicroscopic examination made it possible to reveal that the maximum number and size of small vestibular glands are determined in the 1st period of adulthood. Starting from the 2nd period of adulthood and up to old age inclusive, there is a decrease in these indicators. The minimum level of individual variability in the size and number of small glands of the vestibule is characteristic in ontogeny for the neonatal period.

The aim was to study the macro-microanatomy and morphometric characteristics of the glands of the right, left and common hepatic ducts in people of different ages under conditions of relative norm.Material and methods. The experimental material included a complex consisting of the left, right and common hepatic ducts obtained from the corpses of 126 persons of different age groups who died from causes not related to the pathology of the digestive system. The glands of the hepatic ducts were selectively stained with methylene blue according to R.D. Sinelnikov, followed by fixation in a saturated solution of ammonium picric acid. The macroscopic structure and microstructure of gels were studied using an MBS-9 stereomicroscope. The analysis included the percentage of glands with different numbers of initial divisions. The studied morphometric parameters included the total number of glands, the length and width of their initial part. Methods of parametric statistics based on the Statistica 6.0 software were used for statistical data processing. Statistical data processing included the calculation of the arithmetic mean indicators, their errors, the analysis of the amplitude of the variation series of each indicator was carried out.Results. According to the results of the study, the number of glands in the walls of the common hepatic duct during postnatal ontogenesis was 1.30–1.84 times higher (p<0.05) compared to the right hepatic duct and 1.39–2.13 times higher (p<0.05) than the same indicator in the walls of the left hepatic duct. There was also a tendency according to which the size of the initial section of the glands of the common hepatic duct was larger than that of the right and left hepatic ducts. The minimum and maximum individual values of the total number of glands, the length and width of the initial section in the walls of the common hepatic duct were also higher in comparison with the analogous parameters of the right and left hepatic ducts.Conclusion. Age-related, regional and individual characteristics of the number and size of the glands of the hepatic ducts have been revealed; variants of the shape of the glands in different age periods have been determined, which is important not only for the development of a new scientific direction – morphological exocrinology, but also for gastroenterology, surgery of the extrahepatic biliary tract.

Health And Well Being

The impact of shift and night work on health shows a high inter- and intra-individual variability, both in terms of kind of troubles and temporal occurrence, related to various intervening factors dealing with individual characteristics, lifestyles, work demands, company organisation, family relations and social conditions. The way we define "health" and "well-being" can significantly influence appraisals, outcomes and interventions. As the goal is the optimisation of shiftworkers' health, it is necessary to go beyond the health protection and to act for health promotion. In this perspective, not only people related to medical sciences, but many other actors (ergonomists, psychologists, sociologists, educators, legislators), as well as shiftworkers themselves. Many models have been proposed aimed at describing the intervening variables mediating and/or moderating the effects; they try to define the interactions and the pathways connecting risk factors and outcomes through several human dimensions, which refer to physiology, psychology, pathology, sociology, ergonomics, economics, politics, and ethics. So, different criteria can be used to evaluate shiftworkers' health and well-being, starting from biological rhythms and ending in severe health disorders, passing through psychological strain, job dissatisfaction, family perturbation and social dis-adaptation, both in the short- and long-term. Consequently, it appears rather arbitrary to focus the problem of shiftworkers' health and tolerance only on specific aspects (e.g. individual characteristics), but a systemic approach appears more appropriate, able to match as many variables as possible, and aimed at defining which factors are the most relevant for those specific work and social conditions. This can support a more effective and profitable (for individuals, companies, and society) adoption of preventive and compensative measures, that must refer more to "countervalues" rather than to "counterweights".

Background: Neonatal period is a period from birth to under 28 days of life. The common causes of mortality and morbidity in our region are preventable, among which neonatal sepsis is the commonest one. Most of the deaths occur within 7 days of life. Objectives: To study the clinical profile, pattern of diseases, causes of morbidity and mortality amongst newborns. Materials and methods: A hospital based descriptive study was done among total 967 newborns including both inborn and out born admitted in NICU, NGMC from January 2016 to December 2016. Age, sex, gestational age, diagnosis at admission, outcome of admitted th newborns were the main variables under study. Data was entered in Excel and analyzed using SPSS 20th version. Data were presented through pie, bar graph and table with frequency and percentage. Results: Male were predominant in the study (65%). One third of the admitted newborns were preterms. Half of the admitted newborns were admitted on their first day of life. Neonatal sepsis was the most common cause of admission. Deaths occured in 7.4%of total babies. Seventy-six percent got improved after treatment. Only 2.8% were referred to higher center. Conclusions: Most of the neonates got admitted in first day of life with commonest cause being neonatal sepsis. Recovery rate was satisfactory. To reduce the mortality and morbidity of neonates, we need to increase awareness level in general population and proper aseptic practices in medical practitioners.

Abstract: Apuleia molaris spruce ex benth, commonly known in Brazil as "amarelão," is a fast-growing forest plant with a potential for use in reforestation; however, there is little information about the physiology and morphology of its fruits, seeds, and seedlings. Thus, the objective of this work was to describe the morphology of the fruits, seeds, and seedlings, in addition to the anatomic patterns of seedlings, as a contribution to the technical-scientific knowledge and production of amazonian species for reforestation in the state of Pará. For this purpose, the morphological descriptions followed the parameters from specialized literature and the common techniques used in plant anatomy. The species presents leguminous fruit; seeds with pleurogram, average dimensions of 51.21, 21.33, and 2.09 mm length, width, and thickness, respectively; and seedlings with eophyll and pinnate metaphylls, cordiform, phanerocotylar germination, epigaeous, and foliaceous. Eophylls and metaphylls present uniseriate epidermis, collateral and dorsiventral vascular bundle. The morphological characteristics may help in field identification and in the identification of young plants, aiding the production of seedlings of this species. Furthermore, anatomically, the hypocotyl has no striking differences from the root.

Erynia pieris Li & Humber (Entomophthorales: Entomophthoraceae) is described for a fungus originally isolated from Pieris rapae (Lepidoptera: Pieridae). The fungus grows and sporulates well on standard mycological media. Primary conidia are ovoid to obovoid, 21–33 × 11–24 μm (averaging 26 × 16 μm, with a length/width ratio of 1.60), uninucleate, bitunicate, and forcibly discharged from bifurcate or irregularly branched conidiophores. Secondary through quaternary conidia are more nearly globose than primary conidia. Nuclei contain prominent, readily stained chromosomal granulations. Cystidia emerge from the host body before the conidiophores, are only slightly thicker than conidiophores at the base, and taper to a blunt apex. Rhizoids are monohyphal on lepidopterans, are little thicker than vegetative hyphae, and have no discoid terminal holdfast; rhizoidal morphology varies considerably between lepidopterous and nonlepidopterous hosts. No resting spores were observed. Laboratory studies demonstrated the pathogenicity of cultures of this fungus on several other lepidopterans (Estigmene acrea, Heliothis zea, Heliothis virescens, Trichoplusia ni, Spodoptera eridania). on the common housefly (Musca domestica), and on potato leafhopper (Etnpoasca fabae). Erynia virescens (Thax.) Remaudière & Hennebert is emended and compared with E. pieris; both species are assigned to Erynia subg. Furia (Batko) Li & Humber, comb. nov. Furia differs from other Erynia subgenera by the presence of cystidia as thick as conidiophores and of rhizoids no thicker than vegetative hyphae and having no differentiated terminal holdfasts, and by the absence of secondary capilliconidia.

The Morris Water Maze (MWM) is a behavioral test widely used in the field of neuroscience to evaluate spatial learning memory of rodents. However, the interpretation of results is often impaired by the common use of statistical tests based on independence and normal distributions that do not reflect basic properties of the test data, such as the constant-sum constraint. In this work, we propose to analyze MWM data with the Dirichlet distribution, which describes constant-sum data with minimal hypotheses, and we introduce a statistical test based on uniformity (equal amount of time spent in each quadrant of the maze) that evaluates memory impairments. We demonstrate that this test better represents MWM data and show its efficiency on simulated as well as in vivo data. Based on Dirichlet distribution, we also propose a new way to plot MWM data, showing mean values and inter-individual variability at the same time, on an easily interpretable chart. Finally, we conclude with a perspective on using Bayesian analysis for MWM data.

The results of processing the data of continuous recording of body temperature using loggers obtained with the enclosure keeping 23 individuals of the common viper Vipera berus L. in Karelia (62.068310°N, 33.958824°E) are presented. Nine temperature characteristics, subdivided into 2 groups, were quantitatively evaluated – thermoecological, describing the dependence of the course of the viper’s body temperatures on the heat flux of the medium, and thermophysiological, stable parameters of thermoregulation. The factors that determine the variability of temperature characteristics are considered: time of day, weather conditions, morphometric indicators of an individual. A wide individual variability of thermoecological indicators and low variability of thermophysiological indicators were revealed, which was not associated with significant differences in different individuals. The parameter “maximum voluntary temperature”, which characterizes body temperature while avoiding overheating, is the closest to the physiological parameter of thermoregulation; obtaining such data is a very laborious process associated with deciphering the snake’s behavior from video recordings. An indicator that gives close values to the maximum voluntary temperature, which has a very simple calculation algorithm – “median active temperature (for a sample of temperatures above 30°C)”; however, it requires a volumetric series of continuously recorded temperature records for analysis. An accurate, statistically robust “maximum typical temperature” parameter gives an idea of the true maximum temperature characteristic of a species, but has a complex calculation method. These thermophysiological parameters are recommended to be used for intrapopulation and interspecies comparisons.

AbstractIn situations of negative energy balance (NEB) due to feed scarcity or high physiological demands, body energy reserves (BR), mainly stored in adipose tissues, become the main sources of energy for ruminants. The capacity to mobilize and restore such BRs in response to different challenges is of major concern in the current context of breeding for resilience. Body condition score (BCS) is a common, practical indicator of BR variations throughout successive productive cycles, and quantitative tools for characterizing such dynamics at the individual level are still lacking. The main objective of this work was to characterize body condition dynamics in terms of BR mobilization and accretion capacities of meat sheep during their productive lifespan through a modelling approach.The animal model used in this work was the reproductive meat ewe (n = 1478) reared in extensive rangeland. Regular measurements of BCS for each productive cycle were used as the indicator of BR variations. A hybrid mathematical model and a web interface, called PhenoBR, was developed to characterize ewes’ BCS variations through four synthetic and biologically meaningful parameters for each productive cycle i: BR accretion rate , BR mobilization rate , plus the time of onset and the duration of the BR mobilization, and ΔTi, respectively.The model converged for all the ewes included in the analysis. Estimation of the parameters indicated the inter-individual variability for BR accretion and mobilization rates, and for the length of the mobilization period. Body reserve mobilization rates were closely correlated between productive cycles. Significant correlations between BR mobilization and accretion rates suggest that the two processes are biologically linked. Parameters kp and kb decreased as parity increased. BR mobilization rate and duration increased as litter size increased, while BR accretion rate decreased.Individual characterization of animals by these parameters makes it possible to rank them for their efficiency in the use of body reserves when facing NEB challenges. Such parameters could contribute to better management and decision-making by farmers and advisors, e.g. by adapting feeding systems to the individual characteristics of BR dynamics, or by geneticists as criteria to develop future animal breeding programs including BR dynamics for more robust and resilient animals.

<p>The extreme ecological success of insect societies is frequently attributed to the division of labour within their colonies (Chittka & Muller, 2009; Holldobler & Wilson, 2009; E. Wilson & Hölldobler, 2005). Yet, we are far from understanding the causes and consequences of division of labour, implying workers’ specialization (Chittka & Muller, 2009; Dornhaus, 2008). Moreover, little studied is the behaviour of individual workers (Jeanson & Weidenmüller, 2013). Social wasps (Hymenoptera: Vespidae) have received less attention than social bees and ants, and our knowledge of basic aspect of their ecology is still poor (Jeanne, 1991; Greene, 1991). With my thesis, I aimed to contribute to a better understanding of the common wasp (Vespula vulgaris) foraging ecology and organization of labour. With a particular attention to their foraging behaviour, I investigated the inter-individual variability among wasp workers and their cooperation.  My thesis shows evidence of information sharing and co-ordination in V. vulgaris foragers’ activity. In fact, the discovery and choice of resources by wasp foragers was assisted by information provided by experienced nestmates (Chapter 2). When resources known to portion of the workforce became newly available, the foraging effort of the whole colony increased. My observations of common wasps are hence consistent with foraging activation mechanisms and suggest piloting (in which one individual leads one or more nestmates to a resource) as a possible foraging recruitment mechanism in social wasps.  I found huge variation in lifetime activity, task performance, and survival among common wasp workers (Chapter 3). Some individuals specialized on alternative foraging tasks over their lifetime, and a minority individuals performed a disproportionately high number of foraging trips (elitism). Foragers appeared to become more successful with age, accomplishing more trips and carrying heavier fluid loads. Compared to smaller nestmates, larger wasps contributed more to the colony foraging economies. High mortality was associated with the beginning of the foraging activity, relative to lower mortality in more experienced workers.  I evaluated the performance of common wasp workers within the same insect colony, and found empirical support for the hypothesis that specialist foragers are more efficient than generalists (Chapter 4). In fact, V. vulgaris behavioural specialists performed more trips per foraging day and their trips tended to be shorter. Despite their more intense foraging effort, specialists lived longer than generalists.  I investigated the intra-colonial variation in the sting extension response (SER) of common wasps, measured as a proxy for individual aggressiveness (Chapter 5). I found that wasps vary greatly in their SER and that individuals change during their life. Aggressive individuals tended to become more docile, while docile individuals more aggressive. Older wasps tended to be more aggressive. Wasp size was not significantly related to the SER. Wasp foragers had a less pronounced sting extension than individuals previously involved in nest defence. For the same individual, the aggressive response was proportional to the intensity of the negative stimulus.</p>

Introduction This study describes the use of prescription medications and psychological counselling in the past 12 months among Canadian adults with a self-reported mood and/or anxiety disorder diagnosis; the sociodemographic and clinical characteristics associated with their use; and reasons for not using them. Methods We used data from the 2014 Survey on Living with Chronic Diseases in Canada—Mood and Anxiety Disorders Component. The study sample (n = 2916) was divided into four treatment subgroups: (1) taking medication only; (2) having received counselling only; (3) both; or (4) neither. We combined the first three subgroups and carried out descriptive and multivariate logistic regression analyses comparing those who are taking medication and/or have received counselling in the past 12 months, versus those doing neither. Estimates were weighted to represent the Canadian adult household population living in the 10 provinces with diagnosed mood and/or anxiety disorders. Results The majority (81.8%) of Canadians with a mood and/or an anxiety disorder diagnosis reported they are taking medications and/or have received counselling (47.6% taking medications only; 6.9% received counselling only; and 27.3% taking/having received both). Upon controlling for individual characteristics, taking medications and/or having received counselling was significantly associated with older age; higher household income; living in the Atlantic region or Quebec versus Ontario; and having concurrent disorders or mood disorders only. Symptoms controlled without medication was the most common reason for not taking medications, while preferring to manage on their own and taking medications were among the common reasons for not having received counselling. Conclusion The majority of Canadian adults with a mood and/or an anxiety disorder diagnosis are taking medications, while few have received counselling. Insights gained regarding the factors associated with these treatments, and reasons for not using them, emphasize the importance of discussing treatment options and perceived barriers with patients to ensure they receive the best treatment according to their needs and preference.
