Influence of enclosure size on growth of breast and leg muscle fibers in domestic fowl

This experiment evaluated the growth of breast and leg muscle fibers of domestic fowl raised in two enclosure sizes (SE: Small Enclosure, 1.125 m2/10 birds; LE: Large Enclosure, 5.25 m2/10 birds). In breast muscles, the number of fibers per area decreased over time and higher values were observed in broilers housed in SE compared to LE. The fiber size increased with age and was greater in LE than SE at 56 days of age, suggesting greater hypertrophic growth of fibers in breast muscle for broilers maintained in LE. In leg muscles, the muscle cross-sectional area was greater for broilers raised in LE than SE at 56 days of age and decreased from 42 to 56 days of age in broilers raised in SE, suggesting leg muscle atrophy in these birds. The Fast Glycolytic (FG), Fast Oxidative-Glycolytic (FOG) and Slow Oxidative (SO) fibers grew until 42 days of age in both enclosure sizes. The area of FOG fibers was greater in broilers raised in LE than those in SE at 28 and 56 days of age; in LE-raised broilers, the SO area was greater at 28, 42 and 56 days of age, suggesting that the muscles of broilers housed in LE are more oxidative. The BW gain was greater for broilers raised in LE than SE, whereas BW, feed intake and feed conversion were not influenced by enclosure size. Thus, the enclosure space affected hypertrophic growth and metabolic characteristics of breast and leg muscle fibers. © Asian Network for Scientific Information, 2012.

Identification of phospholipase C zeta in normospermic and teratospermic domestic cat sperm

In mammalian species, oocyte activation is initiated by oscillations in the intracellular concentration of free calcium ([Ca2+]i), which are also essential to allow embryonic development. To date, evidence supporting the hypothesis that a sperm factor is responsible for initiating oocyte activation has been presented in various mammalian species. Among the possible candidates to be the active sperm factor is the novel sperm-specific phospholipase C ζ (PLCζ), which besides its testis-specific expression is capable of initiating [Ca2+]i oscillations. In this study, we investigated the presence of PLCζ in the sperm of the domestic cat and whether normospermic and teratospermic cats differ in their PLCζ expression. Immunoblotting with anti-PLCζ antibodies confirmed the presence of an immunoreactive band of ~70 kDa in whole sperm lysates of domestic cat as well as in both soluble and insoluble fractions from this sperm. Additional immunoreactive bands, probably C- and N-terminal truncated versions of PLCζ, were also visualized in the soluble sperm fractions. Interestingly, immunoreactivity of PLCζ was detectable in teratospermic sperm, although with slightly less intensity than in normospermic sperm. In conclusion, domestic cat sperm express PLCζ in both cytosolic and high-pH fractions, which is consistent with data in other mammals. Sperm from teratospermic cats also express PLCζ, albeit at reduced concentrations, which may affect the fertility of these males. © 2013 Elsevier Inc..

Violence against children and adolescents: awareness and attitudes of Brazilian dentists

Violence against children and adolescents, ranging from negligence to sexual abuse, is an imperative public health problem. The ill treatments are considered as nonaccidental traumas, actions or omissions against children, who suffer physical or emotional violence. The main perpetrators are fathers, mothers, guardians, family, friends or the children‘s primary caretaker. It is very important to identify abuse cases, because this allows proper medical and legal intervention. In Brazil, the law n. 8.069, of July 13, 1990, known as the ECA -Statute for Children and Adolescents (SCA), stipulates the obligation to report suspected or confirmed cases of ill treatment against a child or adolescent to the Guardianship Council of the respective locality. The health professionals play a crucial role with regard to identifying cases of violence, collecting information, making early diagnosis of suspect cases and reporting such cases to the authorities. The dentists can contribute significantly, as most injuries occur in the orofacial region. Bite marks, burns, bruising, among others, are easily identified during a dental consultation. The aim of this work was to verify the awareness and attitudes of Brazilian dentists concerning violence against children and adolescents. This research was approved by the Research Ethics Committee of the Faculty of Dentistry of Araraquara – São Paulo State University (FOAr – UNESP). Sixty-three dentists answered an open and closed questionnaire concerning their formation, knowledge, experience and attitudes towards ill-treated children and adolescents. Among other results, thirty-nine dentists (61.9%) affirmed to have the means to identify illtreatment cases, 13 (20.6%) reported having some experience on this matter, but only 8 reported the cases to the Council of Guardianship, as determined by Brazilian law. Twenty percent of the reasons presented for not notifying the Council were fear of reprisal, and 60.0% were uncertain concerning the ethical and legal implications. Physical violence was the most reported form of identified violence (76.9%), followed by negligence (38.5%). Among the 13 professionals that had experience with violence cases, in 10 cases the perpetrators were identified – in 70.0% of the cases, the parents were the originators of such violence. It was concluded that further formation and orientation are necessary, in order to prepare dentists to act correctly when, during their professional activities, they encounter cases of violence against children and adolescents.

Violence against children and adolescents: the importance of knowledge of the spectrum of bruise colors in its diagnosis

Introduction: One of the violence types more observed against children is the physical abuse, which produces many types of traumatic injuries. Contusions are common trauma signs and may indicate aggression when frequently present in locations where accidental injuries are rare. Contusions in skin undergo color changes with the passage of time, and such change in color is called “spectrum of bruise colors of Legrand du Saulle”. Thus, it is possible to estimate the age of the lesion based on the evaluation of color. Injuries caused by child abuse often reach regions of head, face and neck, because they are exposed and easily accessible. Therefore, the dentist is responsible with regard to the diagnosis and the actions to be undertaken against the cases of child abuse. Objective: To present and discuss the significance of the spectrum of bruise colors as a considerable visible trace in suspicion of violence against children and adolescents, during dentists’ clinical routine. Literature review: The study of the “spectrum of bruise colors of Legrand du Saulle” refers to the estimation of the age of the injury, in respect to the color change. The application of this study is of great value for identify if a lesion occurred from a single incident or from multiple incidents, especially in cases where it occurs in the same region of the body, indicative of repetitive trauma. Conclusion: The spectrum of bruise colors is very important for health professionals, such as dentists, for the identification or suspicion of cases of abuse against children and adolescents. As great part of the lesions originated of abuse involve the areas of head and neck, it is unacceptable that these professionals are unaware of the basic signs to help in early diagnosis, which is the case of the colors of the lesions. However, concerning the chronology of the spectrum of bruise colors, it is not possible to establish rigorous times.

Burden of maternal bipolar disorder on at-risk offspring: A controlled study on family planning and maternal care

Introduction: Bipolar disorder (BD) is a highly incapacitating disease typically associated with high rates of familial dysfunction. Despite recent literature suggesting that maternal care is an important environmental factor in the development of behavioral disorders, it is unclear how much maternal care is dysfunctional in BD subjects. Objective: The objective of this study was to characterize maternal care in DSM-IV/SCID diagnosed BD type I subjects compared to healthy controls with (PD) and without (NPD) other psychiatric diagnoses. Materials and methods: Thirty-four BD mothers and 106 controls underwent an interview about family planning and maternal care, obstetrical complications, and mother-child interactions. K-SADS-PL questions about violence exposure were used to ascertain domestic violence and physical/sexual abuse. Results: BD mothers were less likely to have stable unions (45.5%; p < 0.01) or to live with the biological father of their children (33.3%; p < 0.01), but had higher educational level and higher rates of social security use/retirement. They also had fewer children and used less contraceptive methods than controls. Children of BD women had higher rates of neonatal anoxia, and reported more physical abuse (16.1%; p = 0.02) than offspring of NPD mothers. Due to BD mothers' symptoms, 33.3% of offspring suffered physical and/or psychological abuse. Limitations: Post hoc analysis, and the use of questions as a surrogate of symptoms as opposed to validated instruments. Conclusion: This is one of few reports confirming that maternal care given by BD women is dysfunctional. BD psychopathology can lead to poor maternal care and both should be considered important environmental risk factors in BD, suggesting that BD psychoeducation should include maternal care orientation.

Essays on the Empirical Analysis of Economic and Political Development in Sub-Saharan Africa

In Sub-Saharan Africa, non-democratic events, like civil wars and coup d'etat, destroy economic development. This study investigates both domestic and spatial effects on the likelihood of civil wars and coup d'etat. To civil wars, an increase of income growth is one of common research conclusions to stop wars. This study adds a concern on ethnic fractionalization. IV-2SLS is applied to overcome causality problem. The findings document that income growth is significant to reduce number and degree of violence in high ethnic fractionalized countries, otherwise they are trade-off. Income growth reduces amount of wars, but increases its violent level, in the countries with few large ethnic groups. Promoting growth should consider ethnic composition. This study also investigates the clustering and contagion of civil wars using spatial panel data models. Onset, incidence and end of civil conflicts spread across the network of neighboring countries while peace, the end of conflicts, diffuse only with the nearest neighbor. There is an evidence of indirect links from neighboring income growth, without too much inequality, to reduce the likelihood of civil wars. To coup d'etat, this study revisits its diffusion for both all types of coups and only successful ones. The results find an existence of both domestic and spatial determinants in different periods. Domestic income growth plays major role to reduce the likelihood of coup before cold war ends, while spatial effects do negative afterward. Results on probability to succeed coup are similar. After cold war ends, international organisations seriously promote democracy with pressure against coup d'etat, and it seems to be effective. In sum, this study indicates the role of domestic ethnic fractionalization and the spread of neighboring effects to the likelihood of non-democratic events in a country. Policy implementation should concern these factors.

Disclosure, discrimination and desire: experiences of Black and South Asian gay men in Britain

Using findings from a qualitative investigation based on in-depth email interviews with 47 Black and South Asian gay men in Britain, this paper explores the cross-cutting identities and discourses in relation to being both gay and from an ethnic minority background. Taking an intersectional approach, detailed accounts of identity negotiation, cultural pressures, experiences of discrimination and exclusion and the relationship between minority ethnic gay men and mainstream White gay culture are presented and explored. The major findings common to both groups were: cultural barriers limiting disclosure of sexuality to family and wider social networks; experiences of discrimination by White gay men that included exclusion as well as objectification; a lack of positive gay role models and imagery relating to men from minority ethnic backgrounds. Among South Asian gay men, a major theme was regret at being unable to fulfil family expectations regarding marriage and children, while among Black gay men, there was a strong belief that same-sex behaviour subverted cultural notions related to how masculinity is configured. The paper concludes by highlighting the importance of social location, particularly education and income, when examining the intersection of ethnicity and sexuality in future research.

Yolk Androstenedione in Domestic Chicks (Gallus Gallus Domesticus): Uptake and Sex-Dependent Alteration of Growth and Behavior

In birds, causes and consequences of variation in maternally-derived steroids in egg yolk have been the subject of intense experimentation. Many studies have quantified or manipulated testosterone ("T") and one of its immediate precursors, androstenedione ("A4") - often lumping the two steroids as "androgens" and treating them as functionally equivalent. However, yolk A4 is deposited in substantially higher concentrations than T, binds only weakly to the androgen receptor, and is readily converted into either T or estrone by steroidogenic enzymes present during embryonic development. Thus it may not be appropriate to assume that A4 has the same effect as T. In addition, A4's metabolic fate is likely to differ between females and males. The goals of this study were to examine the sex-specific uptake and metabolism of yolk A4 and consequences of elevated levels of yolk A4 on development and behavior of domestic chicks. Eggs were injected with 2mu Ci of tritiated androstenedione; radioactivity was detected in all tissues of day 7 and day 16 embryos and found in both aqueous and organics phases of day 7 yolk, with no difference between sexes. A second set of eggs was injected with 125ng of A4. A4 increased growth of morphological traits (tarsus, beak) in females, but not males. A4 males had smaller combs than controls; there was no treatment effect in females. A4 reduced tonic immobility behavior in both sexes. The results of this study illustrate the importance of distinguishing both between androgens and between sexes when investigating avian endocrine maternal effects. Copyright 2013 Elsevier Inc.

The role of warning behaviors in threat assessment: an exploration and suggested typology

The concept of warning behaviors offers an additional perspective in threat assessment. Warning behaviors are acts which constitute evidence of increasing or accelerating risk. They are acute, dynamic, and particularly toxic changes in patterns of behavior which may aid in structuring a professional's judgment that an individual of concern now poses a threat - whether the actual target has been identified or not. They require an operational response. A typology of eight warning behaviors for assessing the threat of intended violence is proposed: pathway, fixation, identification, novel aggression, energy burst, leakage, directly communicated threat, and last resort warning behaviors. Previous research on risk factors associated with such warning behaviors is reviewed, and examples of each warning behavior from various intended violence cases are presented, including public figure assassination, adolescent and adult mass murder, corporate celebrity stalking, and both domestic and foreign acts of terrorism. Practical applications and future research into warning behaviors are suggested. Copyright © 2011 John Wiley & Sons, Ltd.

Neighbourhoods Mobilise the Troops - Community Organising, Violence and Governmentality

The article reflects on the difficult relation between community work against domestic violence and local crime prevention under the conditions of the neoliberal state that cuts down on social benefits and promotes self-help, active citizenship and self-responsibility instead while at the same time restoring the punishing state with its strict regime of law-and-order. The author describes a project Tarantula - she started herself while being a social worker in Hamburg, Germany. Tarantula was aimed at strengthening social networks and the neighbours' willingness to get involved in favour of affected women. Although conceptualized as an emancipatory approach referring to community organizing in the tradition of social movements it is questionable whether and how this can really work in the current situation. At present, the field of crime control is being reconfigured as a result of political and administrative decisions, which, for their part, are based on a new structure of social relations and cultural attitudes. The demolition of the 'welfare state' means the re-coding of the security policy that facilitates the development of interventionist techniques that govern and control individuals through their own ability to act.

The Care and Shelter of Children and Adolescents in Brazil: Expressions of Social Issues

The future of Brazilian children who have the protection offered by familial bonds is threatened by social inequities that force them to seek shelter and grow up in shelters. According to the Institute of Applied Economic Research, an estimated 20,000 children and adolescents are served by institutions. The majority of these children are afro-descendent males between the ages of seven and fifteen years old. Of those researched, 87.6% have families (58.2% receive visits from their families, 22.7% are rarely visited by their families and 5.8 are legally prohibited from contacting or being by their families). The percentage of children and adolescents “without families” or with “missing families” is 11.3%. There is no information available for 2% of the children and adolescents residing in shelters. The principle factors that necessitate the placement of Brazilian children in institutions that provide care and shelter include poverty (including children forced to work, sell drugs or beg, for example); domestic violence; chemical dependence of parents or guardians; homelessness; death or parents or guardian; imprisonment of their parents; and sexual abuse committed by their parents or guardians. The issue of abandoned children and adolescents and their care and shelter in the Brazilian context expresses a perverse violation of Child and Adolescent Rights.

Bovine viral diarrhea virus in free-ranging wild ruminants in Switzerland: low prevalence of infection despite regular interactions with domestic livestock

ABSTRACT: BACKGROUND: In the frame of an eradication program for bovine viral diarrhea (BVD) in Swiss livestock, the question was raised whether free-ranging wildlife could threaten the success of this sanitary measure. Therefore, we conducted serological and virological investigations on BVD virus (BVDV) infections in the four indigenous wild ruminant species (roe deer, red deer, Alpine chamois and Alpine ibex) from 2009 to 2011, and gathered information on interactions between wild and domestic ruminants in an alpine environment by questionnaire survey. RESULTS: Thirty-two sera out of 1'877 (1.7%, 95% confidence interval [CI] 1.2-2.4) were seropositive for BVDV, and a BVDV1 sub genotype h virus was found in a seropositive chamois (0.05%, 95% CI 0.001-0.3). The seropositive animals originated from sub-alpine or alpine regions and significantly more seropositive red deer, chamois and ibex than roe deer were found. There were no statistically significant differences between sampling units, age classes, genders, and sampling years. The obtained prevalences were significantly lower than those documented in livestock, and most positive wild ruminants were found in proximity of domestic outbreaks. Additionally, BVDV seroprevalence in ibex was significantly lower than previously reported from Switzerland. The survey on interspecific interactions revealed that interactions expected to allow BVDV transmission, from physical contacts to non-simultaneous use of the same areas, regularly occur on pastures among all investigated ruminant species. Interactions involving cervids were more often observed with cattle than with small ruminants, chamois were observed with all three domestic species, and ibex interacted mostly with small ruminants. Interactions related to the use of anthropogenic food sources were frequently observed, especially between red deer and cattle in wintertime. CONCLUSIONS: To our knowledge, this is the first report of BVDV RNA isolated from an Alpine chamois. Nevertheless, our results suggest that BVDV infections are only sporadic in Swiss wild ruminants, despite regular occurrence of interactions with potentially infected livestock. Overall, serological, virological and ethological data indicate that wildlife is currently an incidental spill-over host and not a reservoir for BVDV in Switzerland.

Implementation status of error disclosure standards reported by Swiss hospitals

QUESTION UNDER STUDY To establish at what stage Swiss hospitals are in implementing an internal standard concerning communication with patients and families after an error that resulted in harm. METHODS Hospitals were identified via the Swiss Hospital Association's website. An anonymous questionnaire was sent during September and October 2011 to 379 hospitals in German, French or Italian. Hospitals were asked to specify their hospital type and the implementation status of an internal hospital standard that decrees that patients or their relatives are to be promptly informed about medical errors that result in harm. RESULTS Responses from a total of 205 hospitals were received, a response rate of 54%. Most responding hospitals (62%) had an error disclosure standard or planned to implement one within 12 months. The majority of responding university and acute care (75%) hospitals had introduced a disclosure standard or were planning to do so. In contrast, the majority of responding psychiatric, rehabilitation and specialty (53%) clinics had not introduced a standard. CONCLUSION It appears that Swiss hospitals are in a promising state in providing institutional support for practitioners disclosing medical errors to patients. This has been shown internationally to be one important factor in encouraging the disclosure of medical errors. However, many hospitals, in particular psychiatric, rehabilitation and specialty clinics, have not implemented an error disclosure policy. Further research is needed to explore the underlying reasons.
