A Umemoto, C B Holroyd
Anterior cingulate cortex (ACC) is involved in cognitive control and decision-making but its precise function is still highly debated. Based on evidence from lesion, neurophysiological, and neuroimaging studies, we have recently proposed a critical role for ACC in motivating extended behaviors according to learned task values (Holroyd and Yeung, 2012). Computational simulations based on this theory suggest a hierarchical mechanism in which a caudal division of ACC selects and applies control over task execution, and a rostral division of ACC facilitates switches between tasks according to a higher task strategy (Holroyd and McClure, 2015)...

REVIEW
Vargas-Bello-Pérez E, Larraín R E
In the last decades there has been an increased consumer interest in the fatty acid (FA) composition of ruminant meat due to its content of saturated FA, which have been implicated in diseases associated with modern life. However, recent studies have questioned the recommendations to reduce intake of fat, saturated FA and cholesterol as a mean of reducing risk of cardiovascular disease. Interestingly, ruminant meat has some bioactive lipids such as C18:1t11 and C18:2 c9, t11 which have been reported to have positive effects on human health...

Alcelaphine herpesvirus 1 (AlHV-1) is a gammaherpesvirus carried asymptomatically by wildebeest. Upon cross-species transmission, AlHV-1 induces malignant catarrhal fever (MCF), a fatal lymphoproliferative disease of ruminants, including cattle. The strain C500 has been cloned as an infectious, pathogenic bacterial artificial chromosome (BAC) that is used to study MCF. Although AlHV-1 infection can be established in cell culture, multiple passages in vitro cause a loss of virulence associated with rearrangements of the viral genome...

Goats are an important source of livelihood especially in smallholder communities. Infections with gastrointestinal nematodes (GIN) remain the most prevalent parasitic diseases affecting small ruminants. The study was conducted to assess management, the level of knowledge and control of gastrointestinal nematodes. Surveys were conducted in Chipinge, Shurugwi, Binga, Tsholotsho and Matobo districts, representing the five natural/agro-ecological regions (NR) in Zimbabwe. Data was collected in 135 households using a pre-tested semi-structured questionnaire...

Mineral salt bricks are often used in cow raising as compensation for mineral losses to improve milk yield, growth, and metabolic activity. Generally, effects of minerals are partially thought to result from improvement of microbial metabolism, but their influence on the rumen microbiota has rarely been documented to date. In this study, we investigated the response of microbiota to mineral salt in heifer and adult cows and evaluated ruminal fermentation and enteric methane emissions of cows fed mineral salts...

Methane (CH4) emissions by human activities have more than doubled since the 1700s, and they contribute to global warming. One of the sources of CH4 is produced by incomplete oxidation of feed in the ruminant's gut. Domestic ruminants produce most of the emissions from animal sources, but emissions by wild ruminants have been poorly estimated. This study (i) scales CH4 against body mass in 503 experiments in ruminants fed herbage, and assesses the effect of different sources of variation, using published and new data; and (ii) it uses these models to produce global estimates of CH4 emissions from wild ruminants...

Moniezia spp. parasitize the intestines of ruminants, causing monieziasis. In this study, the complete mitochondrial (mt) genomes of M. benedeni and M. expansa have been determined, characterized and employed to test the hypothesis that M. benedeni and M. expansa are distinct species by phylogenetic analysis based on the concatenated amino acid sequences derived from 12 protein-coding genes, inferred with Bayesian and Maximum-likelihood methods. The complete mt genomes of M. benedeni and M. expansa were 13,958bp and 13,934bp in size, respectively...

OBJECTIVES: The current study examined whether various types of rumination are distinguishable and the effects of personal growth initiative (PGI) on posttraumatic growth, posttraumatic stress, and depression through adaptive and maladaptive rumination. METHOD: Sample included 292 college students who experienced a potentially traumatic event (PTE). RESULTS: Intrusive and deliberative rumination were found to be distinct factors. However, brooding and reflection, thought to be separate aspects of depression, were a single factor...

Rumination is a maladaptive form of emotion regulation associated with psychopathology. Research with adults suggests that rumination covaries with diurnal cortisol rhythms, yet this has not been examined among adolescents. Here, we examine the day-to-day covariation between rumination and cortisol, and explore whether trait rumination is associated with alterations in diurnal cortisol rhythms among adolescent girls. Participants (N = 122) provided saliva samples 3 times per day over 3 days, along with daily reports of stress and rumination, questionnaires assessing trait rumination related to peer stress, and diagnostic interviews assessing depression and anxiety...

We evaluated the effects of mineral salt supplement on enteric methane emissions, ruminal fermentation and methanogen community of dairy cows over a whole lactation period. Ten Holstein cows fed a total mixed ration (TMR) diet were randomly allocated into two groups, one supplied with mineral salts as the treatment group and the other as the control group. The methane measurement showed that the ingestion of mineral salts lowered enteric methane emissions significantly (P < 0.05), with an average of 10...

The aim of the present study was to use fMRI to examine the neural correlates of engaging in rumination among a sample of remitted depressed adolescents, a population at high risk for future depressive relapse. A rumination induction task was used to assess differences in the patterns of neural activation during rumination versus a distraction condition among 26 adolescents in remission from major depressive disorder (rMDD) and in 15 healthy control adolescents. Self-report depression and rumination, as well as clinician-rated depression, were also assessed among all participants...

The metallothionein 1 (MT1) coding sequence of red deer was identified and compared to orthologous sequences from other mammals. Over 90% identity was observed between red deer MT1 amino acid sequence and MT1 sequences of other ruminants. Liver and kidney samples of red deer were collected from the industrial zinc smelting site of Miasteczko Slaskie and from the Masuria Lake District serving as a pollution-free control site. The concentrations of cadmium (Cd), lead (Pb), copper (Cu) and zinc (Zn) were analyzed by the atomic absorption spectrometry technique (AAS)...

Rumination is associated with exacerbated angry mood. Angry moods may also trigger rumination. However, research has not empirically tested the bidirectional associations of state rumination and anger, as experience sampling methodology can do. We predicted that state anger and rumination would be bi-directionally associated, both concurrently and over time, even controlling for trait anger and rumination. In addition, because mindfulness is associated with rumination and anger at the bivariate level, we examined the effect of trait mindfulness on the bidirectional association between state rumination and anger...

This article discusses various aspects of pastoralism in the Latin American countries with the largest dryland areas. The topics covered include: social, economic and institutional issues; grasslands and their carrying capacity; production systems and productivity rates; competition for forage resources between domestic livestock and wildlife; and the health status of livestock and wildlife. Most grasslands exhibit some degree of degradation. The percentage of offspring reaching weaning age is low: 47-66% of calves and 40-80% of lambs...

Understanding the relationship between ingested plant material and the attached microbiome is essential for developing methodologies to improve ruminant nutrient use efficiency. We have previously shown that perennial ryegrass (PRG) rumen bacterial colonization events follow a primary (up to 4 h) and secondary (after 4 h) pattern based on the differences in diversity of the attached bacteria. In this study, we investigated temporal niche specialization of primary and secondary populations of attached rumen microbiota using metagenomic shotgun sequencing as well as monitoring changes in the plant chemistry using mid-infrared spectroscopy (FT-IR)...

OBJECTIVE: Anxiety and depression are highly prevalent disorders in adolescence. They are associated with deficits in working memory (WM), which also appears to increase rumination, worry, and negative mood. WM training, especially in an emotional context, might help in reducing or preventing these disorders. The current study investigated the direct effects of online emotional WM training on WM capacity, and short- and long-term effects on symptoms of anxiety and depression, and secondary measures of emotional functioning...

Bluetongue (BT) is a disease of ruminants caused by bluetongue virus (BTV) transmitted by biting midges of the Culicoides genus. Outbreaks have been controlled successfully by vaccination, however, currently available BT vaccines have several shortcomings. Recently, we have developed BT Disabled Infectious Single Animal (DISA) vaccines based on live-attenuated BTV without expression of dispensable non-structural NS3/NS3a protein. DISA vaccines are non-pathogenic replicating vaccines, do not cause viremia, enable DIVA and are highly protective...

REVIEW
Kevin E Washburn
As stated many times throughout this issue, localization of the origin of neurologic deficits in ruminants is paramount to successful diagnosis and prognosis. This article serves as a guide to answer 2 questions that should be asked when presented with a ruminant with neurologic dysfunction: Is the lesion rostral or caudal to the foramen magnum? and Does the animal have primary neurologic disease? The answers to these 2 broad questions begin the thought processes to more specifically describe the location and nature of the dysfunction...
