Physical activity and exercise

مَا تَذَرُ مِن شَيۡءٍ أَتَتۡ عَلَيۡهِ إِلَّا جَعَلَتۡهُ كَٱلرَّمِيمِ

and it reduced everything it came up against to shreds

قَالَ قَآئِلࣱ مِّنۡهُمۡ لَا تَقۡتُلُواْ يُوسُفَ وَأَلۡقُوهُ فِي غَيَٰبَتِ ٱلۡجُبِّ يَلۡتَقِطۡهُ بَعۡضُ ٱلسَّيَّارَةِ إِن كُنتُمۡ فَٰعِلِينَ

[Another of them] said, ‘Do not kill Joseph, but, if you must, throw him into the hidden depths of a well where some caravan may pick him up.’

ٱذۡهَبُواْ بِقَمِيصِي هَٰذَا فَأَلۡقُوهُ عَلَىٰ وَجۡهِ أَبِي يَأۡتِ بَصِيرࣰ ا وَأۡتُونِي بِأَهۡلِكُمۡ أَجۡمَعِينَ

Take my shirt and lay it over my father’s face: he will recover his sight. Then bring your whole family back to me.’

وَمِنَ ٱلنَّاسِ مَن يَتَّخِذُ مِن دُونِ ٱللَّهِ أَندَادࣰ ا يُحِبُّونَهُمۡ كَحُبِّ ٱللَّهِۖ وَٱلَّذِينَ ءَامَنُوٓاْ أَشَدُّ حُبࣰّ ا لِّلَّهِۗ وَلَوۡ يَرَى ٱلَّذِينَ ظَلَمُوٓاْ إِذۡ يَرَوۡنَ ٱلۡعَذَابَ أَنَّ ٱلۡقُوَّةَ لِلَّهِ جَمِيعࣰ ا وَأَنَّ ٱللَّهَ شَدِيدُ ٱلۡعَذَابِ

Even so, there are some who choose to worship others besides God as rivals to Him, loving them with the love due to God, but the believers have greater love for God. If only the idolaters could see- as they will see when they face the torment- that all power belongs to God, and that God punishes severely

۞إِنَّ قَٰرُونَ كَانَ مِن قَوۡمِ مُوسَىٰ فَبَغَىٰ عَلَيۡهِمۡۖ وَءَاتَيۡنَٰهُ مِنَ ٱلۡكُنُوزِ مَآ إِنَّ مَفَاتِحَهُۥ لَتَنُوٓأُ بِٱلۡعُصۡبَةِ أُوْلِي ٱلۡقُوَّةِ إِذۡ قَالَ لَهُۥ قَوۡمُهُۥ لَا تَفۡرَحۡۖ إِنَّ ٱللَّهَ لَا يُحِبُّ ٱلۡفَرِحِينَ

Qarun was one of Moses’ people, but he oppressed them. We had given him such treasures that even their keys would have weighed down a whole company of strong men. His people said to him, ‘Do not gloat, for God does not like people who gloat

قَالُواْ ٱبۡنُواْ لَهُۥ بُنۡيَٰنࣰ ا فَأَلۡقُوهُ فِي ٱلۡجَحِيمِ

They said, ‘Build a pyre and throw him into the blazing fire.’

Go with this shirt of mine and cast it upon the face of my father so that he may come to seeing. Joseph said, " Take my shirt to Jacob, for his pain has not ceased from the time he saw the shirt stained with the wolf's blood. The balm will also be my shirt. " When they took the shirt from Egypt, the morning breeze was commanded to take the shirt's scent to Jacob's nostrils so that, before Joseph's messenger could give the good news, he would receive it from the Real's mes- senger and recognize the Real's perfect gentleness and favor toward him. According to the tasting of the recognizers, this is the divine breeze that wanders furtively around the world to the doors of the breasts of the faithful and the tawḤīd-voicers to see where there may be a limpid breast and an empty secret core in which to dwell. Her love came to me before I knew love- it came across a carefree heart and took poss

Among the people are some who take peers apart from God, loving them as if loving God. And those who have faith are more intense in love for God. If this were the only verse in the whole Qur'an about the faithful and God's friends, their eminence and honor would be complete, for the Lord of the Worlds is saying, “They love Me intensely and more completely than the unbelievers love their objects of worship.” Do you not see that every once in a while the unbelievers set up another idol and take up another object of worship. Like poor people, they are content with something carved of wood. Then, when they can, they take down the wooden one and make another from silver or gold. If their love for their object of wor- ship is real, why do they turn away from it toward another? They say that a man met a woman recognizer, and her beauty exercised its influence over his heart. He said, “'My all i

It did not leave anything any soul or property that it came upon without making it like decayed bones like something that is withered and in scattered pieces.

And in Musa, when We sent him to Fir'awn with a manifest authority (38)But (he) turned away along with his hosts, and said: "A sorcerer or a madman. (39)So We took him and his armies, and dumped them into the sea (Yamm), for he was blameworthy (40)And in 'Ad when We sent against them the barren wind (41)It spared nothing that it reached, but blew it into broken spreads of rotten ruins (42)And in Thamud, when they were told: "Enjoy yourselves for a while! (43)But they insolently defied the command of their Lord, so the Sa'iqah overtook them while they were looking (44)Then they were unable to rise up, nor could they help themselves (45)(So were) the people of Nuh before them. Verily, they were a people who were rebellious (46) Lessons from the Destruction of Fir'awn, 'Ad, Thamud, and the People of Nuh Allah the Exalted said, وَفِي مُوسَىٰ إِذْ أَرْسَلْنَاهُ إِلَىٰ فِرْعَوْنَ بِسُلْطَان

One of them namely Judah said ‘Do not kill Joseph but cast him throw him into the bottom of a well ghayābat al-jubb is the darkest recess of a well; a variant reading has the plural ghayābāt so that some caravan might pick him up if you are to do anything’ of what you desire in the way of separating Joseph from us so content yourselves with this solution.

Yet there be people who take to themselves compeers idols besides God that is other than God loving them by magnifying them and being subservient to them as God is loved that is as their love of Him; but those who believe love God more ardently than those who love their compeers because the former never reject God whereas the latter when faced with hardship soon abandon those compeers for God; If he if you O Muhammad (s) were to see those who did evil by taking to themselves compeers when idh here denotes idhā they see read either as active yarawna ‘they see’ or passive yurawna ‘they are made to see’ the chastisement you would see a grave sight that this is because the might the power and the vanquishing altogether a circumstantial qualifier belongs to God and that God is terrible in chastisement according to one reading the person listening to the verse governs the verb yarā ‘he sees’ a

Narrated Abu Tha'labah Al-Khushani:"I said: 'O Messenger of Allah! We are a people who hunt.' He said: 'If you send your dog and you mentioned the Name of Allah upon it, and he catches something for you, then eat it.' I said: 'Even if he kills it?' He said: 'Even if he kills it.' I said: 'We are a people who shoot (at game).' He said: 'What you catch with your bow, then eat it.'" He said: "Then I said:'Indeed we are a people who travel. We come across Jews, Christians, and Zoroastrians, and we do not find vessels other than theirs.' He said: 'If you do not find other than them, then wash them with water, then eat and drink from it

It was narrated that Salamah bin Nufail Al-Kindi said:"I was sitting with the Messenger of Allah when a man said: 'O Messenger of Allah! The people have lost interest in horses and put down their weapons, and they say there is no Jihad, and that war has ended.' The Messenger of Allah turned to face him and said: 'They are lying, now the fighting is to come. There will always be a group among my Ummah who will fight for the truth, for whom Allah will cause some people to deviate, and grant them provision from them, until the Hour begins and until the promise of Allah comes. Goodness is tied to the forelocks of horses until the Day of Resurrection. It has been revealed to me that I am going to die and will not stay long, and you will follow me group after group, striking one another's necks. And the place of safety for the believers is Ash-Sham

It was narrated that Abu Hurairah said:"The Messenger of Allah said: 'There is goodness tied to the forelocks of horses until the Day of Resurrection. And horses are of three types: Those that bring reward to man, those that are a means of protection for a man, and those that are a burden (of sin) for a man. As for those that bring reward, they are kept for the cause of Allah and for Jihad. No fodder enters their stomach but for everything that enters their stomachs, reward is written for him, even if he puts them out to pasture.'" And he quoted the Hadith

Narrated Al-Bara' bin 'Azib: That the Messenger of Allah (ﷺ) said: "Bring me a shoulder blade or tablet." Then he wrote: Not equal are those of believers who sit. 'Amr bin Umm Maktum who was behind him said: "Is there an exemption for me?" So the following was revealed: Except those who are disabled. There are narrations on this topic from Ibn 'Abbas, Jabir and Zaid bin Thabit. This Hadith is Hasan Sahih and it is a Hadith that is Gharib from the narration of Sulaiman At-Taimi from Abu Ishaq. And Shu'bah and Ath-Thawri reported this Hadith from Abu Ishaq

Narrated 'Abdullah bin 'Umar: A man came to Prophet (ﷺ) seeking permission to go for Jihad. So he said: 'Do you have parents (living)? ' He said: 'Yes.' He said: 'Then it is for them that you should perform Jihad.'" [Abu 'Eisa said:] There is something on this topic from Ibn 'Abbas. This Hadith is Hasan Sahih. (One of the narrators) Abul-Abbas is the blind (Al-A'ma) poet (Ash-Sha'ir), from Makkah, and his name is As-Sa'ab bin Farrukh

Physical activity patterns among South-Asian adults: a systematic review.: Physical activity (PA) has many beneficial physical and mental health effects. Physical inactivity is considered the fourth leading risk factor for global mortality. At present there are no systematic reviews on PA patterns among South Asian adults residing in the region. The present study aims to systematically evaluate studies on PA patterns in South Asian countries. A five-staged comprehensive search of the literature was conducted in Medline, Web of Science and SciVerse Scopus using keywords

Reducing the decline in physical activity during pregnancy: a systematic review of behaviour change interventions.: Purpose: Physical activity (PA) typically declines throughout pregnancy. Low levels of PA are associated with excessive weight gain and subsequently increase risk of pre-eclampsia, gestational diabetes mellitus, hypertension disorders, delivery by caesarean section and stillbirth. Systematic reviews on PA during pregnancy have not explored the efficacy of behaviour change techniques or related theory in altering PA behaviour. This systematic review evaluated the content of PA interventions to re

A review of familial correlates of child and adolescent obesity: what has the 21st century taught us so far?

Unlabelled: With the rising prevalence rates of child and adolescent obesity over the last several decades, it is important to examine the extant research to inform future research. Objective: The aim of this paper was to review and critique research investigating familial correlates of child and adolescent obesity in the last decade. Methods: A literature review was conducted between March 2008 and December 2008. Studies published after 2000 that assessed familial associations with child and adolescent obesity in the parental, family functioning, and sibling domains were included in the review. A total of 80 studies met the inclusion criteria. Results: The majority of studies focused on the parental domain. Substantial evidence indicates an association between authoritative parenting style and child/adolescent lower BMI, healthy dietary intake, and physical activity. Also, research on f…

Exercise and mental health: many reasons to move.

The relationship between physical activity and mental health has been widely investigated, and several hypotheses have been formulated about it. Specifically, during the aging process, physical exercise might represent a potential adjunctive treatment for neuropsychiatric disorders and cognitive impairment, helping delay the onset of neurodegenerative processes. Even though exercise itself might act as a stressor, it has been demonstrated that it reduces the harmful effects of other stressors when performed at moderate intensities. Neurotransmitter release, neurotrophic factor and neurogenesis, and cerebral blood flow alteration are some of the concepts involved. In this review, the potential effects of exercise on the aging process and on mental health are discussed, concerning some of the recent findings on animal and human research. The overwhelming evidence present in the literature …

Physical activity and likelihood of depression in adults: a review.

Objective: This review examines original research which has investigated associations between physical activity (PA) dose (i.e. frequency, intensity and duration) and domain and depression or symptoms of depression in adults. Methods: A search of electronic databases and authors' own bibliographic libraries was performed between 2006 and 2007 for original research articles investigating associations between PA and depression in adults. A total of 27 observational and 40 intervention studies were included. Results: Of the studies that focused on the association between duration of PA and likelihood of depression, all five observational studies, and five of the seven intervention studies found both shorter and longer durations of PA were associated with reduced likelihood of depression. Of the studies that focused on the association between intensity of PA and likelihood of depression, fou…

Be smart, exercise your heart: exercise effects on brain and cognition.

An emerging body of multidisciplinary literature has documented the beneficial influence of physical activity engendered through aerobic exercise on selective aspects of brain function. Human and non-human animal studies have shown that aerobic exercise can improve a number of aspects of cognition and performance. Lack of physical activity, particularly among children in the developed world, is one of the major causes of obesity. Exercise might not only help to improve their physical health, but might also improve their academic performance. This article examines the positive effects of aerobic physical activity on cognition and brain function, at the molecular, cellular, systems and behavioural levels. A growing number of studies support the idea that physical exercise is a lifestyle factor that might lead to increased physical and mental health throughout life.

Economic burden of physical inactivity: healthcare costs associated with cardiovascular disease.

Increasingly important objectives for developed and especially for developing countries include increasing the numbers of individuals who do not smoke, who eat healthy diets and who are physically active at levels that are health enhancing. In developing countries, deaths from chronic disease are projected to increase from 56% of all deaths in 2005 to 65% by 2030 (driven largely driven by deaths due to cardiovascular and coronary heart disease); in developed countries, however, the increase is only from 87.5 to 88.5%. The data on physical inactivity presented in this review were derived primarily from World Health Organization (WHO) publications and data warehouses. The prevalence of physical inactivity at less than the levels recommended for enhancing health is high; from 17 to 91% in developing countries and from 4 to 84% in developed countries. In developed countries, physical inactiv…

Nutrition, physical activity, and cardiovascular disease: an update.

Many epidemiological studies have indicated a protective role for a diet rich in fruits and vegetables against the development and progression of cardiovascular disease (CVD), one of the leading causes of morbidity and mortality worldwide. Physical inactivity and unhealthy eating contribute to these conditions. This article assesses the scientific rationale of benefits of physical activity and good nutrition on CVD, especially on atherosclerosis-related diseases. Compelling evidence has accumulated on the role of oxidative stress in endothelial dysfunction and in the pathogenesis of CVD. Reduced nitric oxide (NO) bioavailability due to oxidative stress seems to be the common molecular disorder comprising stable atherosclerotic narrowing lesions. Energy expenditure of about 1000 kcal (4200 kJ) per week (equivalent to walking 1 h 5 days a week) is associated with significant health benefit…

A review of physical activity patterns in pregnant women and their relationship to psychological health.

Regular physical activity contributes positively to physical and psychological health. Adverse consequences of inactivity may be an especially important problem among pregnant women. Up to 60% are inactive during pregnancy. This review found consistent evidence that physical activity is reduced during pregnancy; however, few investigators have sought to quantify physical activity patterns among pregnant women using well validated measures. Some of the barriers to physical activity during pregnancy, such as depression, anxiety and fatigue, have been shown to be attenuated by regular exercise performed by non-pregnant samples. There is a need to better understand the relationships between these factors and physical activity during pregnancy. Available retrospective and prospective results suggest that both leisure time and work-related physical activities are decreased across pregnancy. In…

Promoting health and physical function among cancer survivors: potential for prevention and questions that remain.

Cancer survivors are at increased risk, not only for progressive and recurrent disease, but also other cancers, cardiovascular disease, diabetes, osteoporosis, and functional decline. Lifestyle interventions to improve dietary and physical activity behaviors, and smoking cessation, have the potential to improve the overall health and quality of life of this vulnerable population. Studies on overall health and physical function from 1966 and beyond regarding the impact of behavioral interventions that used randomized and controlled designs were identified through MEDLINE and PubMed searches. Published reports currently exist for 22 exercise interventions, 11 diet-related interventions (excluding those limited to dietary supplements or single nutrients), two diet and exercise interventions, and 10 behavioral-based smoking cessation interventions. Although many interventions have been succe…

Altered respiratory physiology in obesity.

The major respiratory complications of obesity include a heightened demand for ventilation, elevated work of breathing, respiratory muscle inefficiency and diminished respiratory compliance. The decreased functional residual capacity and expiratory reserve volume, with a high closing volume to functional residual capacity ratio of obesity, are associated with the closure of peripheral lung units, ventilation to perfusion ratio abnormalities and hypoxemia, especially in the supine position. Conventional respiratory function tests are only mildly affected by obesity except in extreme cases. The major circulatory complications are increased total and pulmonary blood volume, high cardiac output and elevated left ventricular end-diastolic pressure. Patients with obesity commonly develop hypoventilation and sleep apnea syndromes with attenuated hypoxic and hypercapnic ventilatory responsivenes…

Neurobiology of exercise.

Voluntary physical activity and exercise training can favorably influence brain plasticity by facilitating neurogenerative, neuroadaptive, and neuroprotective processes. At least some of the processes are mediated by neurotrophic factors. Motor skill training and regular exercise enhance executive functions of cognition and some types of learning, including motor learning in the spinal cord. These adaptations in the central nervous system have implications for the prevention and treatment of obesity, cancer, depression, the decline in cognition associated with aging, and neurological disorders such as Parkinson's disease, Alzheimer's dementia, ischemic stroke, and head and spinal cord injury. Chronic voluntary physical activity also attenuates neural responses to stress in brain circuits responsible for regulating peripheral sympathetic activity, suggesting constraint on sympathetic resp…

Behavioural treatments for chronic systemic inflammation: effects of dietary weight loss and exercise training.

Persistent low-grade inflammation, as indicated by higher circulating levels of inflammatory mediators such as C-reactive protein, interleukin-6 and tumour necrosis factor-alpha, is a strong risk factor for several chronic diseases. There are data indicating that decreasing energy intake and increasing physical activity may be effective therapies for reducing overall inflammation. Evidence is strong that circulating levels of inflammatory markers are elevated with total and abdominal obesity, possibly owing to a higher secretion rate of cytokines by adipose tissue in obese people. Moreover, very-low-energy dietary weight loss reduces both circulating markers of inflammation and adipose-tissue cytokine production. Data from several large population-based cohorts show an inverse association between markers of systemic inflammation and physical activity or fitness status; small-scale interv…

Interventions for treating obesity in children.

Childhood obesity remains an important public health concern and prevention programmes should be the priority in order to decrease the prevalence of obesity. The aim of this review is to summarize the most effective types of intervention for treating obesity in children and adolescents. A number of identified strategies used to treat childhood obesity range from lifestyle approaches, pharmacotherapy to surgical intervention. Dietary treatment of obese children and adolescents should aim to ensure adequate growth and development by reducing excessive fat mass accumulation, avoiding loss of lean body mass, improving well-being and self-esteem, and preventing cyclical weight regain. Management protocols involve behaviour modifications, family support, and lifestyle changes which are difficult to put into practice and may require multidisciplinary professional teams. The cornerstone of weigh…

Quantifying physical activity in daily life with questionnaires and motion sensors in COPD.

Accurate assessment of the amount and intensity of physical activity in daily life is considered very important due to the close relationship between physical activity level, health, disability and mortality. For this reason, assessment of physical activity in daily life has gained interest in recent years, especially in sedentary populations, such as patients with chronic obstructive pulmonary disease (COPD). The present article aims to compare and discuss the two kinds of instruments more commonly used to quantify the amount of physical activity performed by COPD patients in daily life: subjective methods (questionnaires, diaries) and motion sensors (electronic or mechanical methods). Their characteristics are summarised and evidence of their validity, reliability and sensitivity is discussed, when available. Subjective methods have practical value mainly in providing the patients' vie…

Neural Dynamics of Shooting Decisions and the Switch from Freeze to Fight.

Real-life shooting decisions typically occur under acute threat and require fast switching between vigilant situational assessment and immediate fight-or-flight actions. Recent studies suggested that freezing facilitates action preparation and decision-making but the neurocognitive mechanisms remain unclear. We applied functional magnetic resonance imaging, posturographic and autonomic measurements while participants performed a shooting task under threat of shock. Two independent studies, in unselected civilians (N = 22) and police recruits (N = 54), revealed that preparation for shooting decisions under threat is associated with postural freezing, bradycardia, midbrain activity (including the periaqueductal gray-PAG) and PAG-amygdala connectivity. Crucially, stronger activity in the midbrain/PAG during this preparatory stage of freezing predicted faster subsequent accurate shooting. Fi…

Comparative Analyses of Zebrafish Anxiety-Like Behavior Using Conflict-Based Novelty Tests.

Modeling of stress and anxiety in adult zebrafish (Danio rerio) is increasingly utilized in neuroscience research and central nervous system (CNS) drug discovery. Representing the most commonly used zebrafish anxiety models, the novel tank test (NTT) focuses on zebrafish diving in response to potentially threatening stimuli, whereas the light-dark test (LDT) is based on fish scototaxis (innate preference for dark vs. bright areas). Here, we systematically evaluate the utility of these two tests, combining meta-analyses of published literature with comparative in vivo behavioral and whole-body endocrine (cortisol) testing. Overall, the NTT and LDT behaviors demonstrate a generally good cross-test correlation in vivo, whereas meta-analyses of published literature show that both tests have similar sensitivity to zebrafish anxiety-like states. Finally, NTT evokes higher levels of cortisol, l…

Further development in the assessment of psychological flexibility: a shortened Committed Action Questionnaire (CAQ-8).

Background: Committed action is a relatively understudied facet of the psychological flexibility model but a potentially important process of overt behaviour in relation to chronic pain. In this study, we take a previously developed measure of committed action, the Committed Action Questionnaire (CAQ), and validate a shorter version. Methods: A total of 664 adults seeking treatment for chronic pain participated in this study. They provided responses to the CAQ and also completed measures of acceptance and health-related daily functioning. Exploratory and confirmatory factor analyses as well as Mokken scaling analysis were used to explore the structure of the CAQ and produce an 8-item version (CAQ-8). Results: A two-factor scale emerged from the analyses that both meets criteria for reliability and validity and performs comparably to the longer original version. In validity correlation an…

Reduced salience and default mode network activity in women with anorexia nervosa.

Background: The neurobiology of anorexia nervosa is poorly understood. Neuronal networks contributing to action selection, self-regulation and interoception could contribute to pathologic eating and body perception in people with anorexia nervosa. We tested the hypothesis that the salience network (SN) and default mode network (DMN) would show decreased intrinsic activity in women with anorexia nervosa and those who had recovered from the disease compared to controls. The basal ganglia (BGN) and sensorimotor networks (SMN) were also investigated. Methods: Between January 2008 and January 2012, women with restricting-type anorexia nervosa, women who recovered from the disease and healthy control women completed functional magnetic resonance imaging during a conditioned stimulus task. Network activity was studied using independent component analysis. Results: We studied 20 women with anore…

Multisystem resiliency moderates the major depression-telomere length association: findings from the Heart and Soul Study.

Major depressive disorder (MDD) has been associated with reduced leukocyte telomere length (LTL). It is not known, however, whether psychosocial and behavioral protective factors moderate this association. In the current study, we examine whether multisystem resiliency--defined by healthy emotion regulation, strong social connections, and health behaviors (sleep and exercise)--predicts LTL and mitigates previously demonstrated associations between depression diagnosis and LTL. LTL was measured, using a quantitative PCR assay, in 954 patients with stable cardiovascular disease in the Heart and Soul Study. In a fully adjusted model, high multisystem resiliency predicted longer LTL (b=80.00, SE=27.17, p=.003), whereas each individual factor did not. Multisystem resiliency significantly moderated the MDD-LTL association (p=.02). Specifically, MDD was significantly related to LTL at 1 SD belo…

Dopamine receptor antagonism disrupts social preference in zebrafish: a strain comparison study.

Zebrafish form shoals in nature and in the laboratory. The sight of conspecifics has been found reinforcing in zebrafish learning tasks. However, the mechanisms of shoaling, and those of its reinforcing properties, are not known. The dopaminergic system has been implicated in reward among other functions and it is also engaged by drugs of abuse as shown in a variety of vertebrates including zebrafish. The ontogenetic changes in dopamine levels and, to a lesser degree, in serotonin levels, have been found to accompany the maturation of shoaling in zebrafish. Thus, we hypothesized that the dopaminergic system may contribute to shoaling in zebrafish. To test this we employed a D1-receptor antagonist and quantified behavioral responses of our subjects using a social preference (shoaling) paradigm. We found significant reduction of social preference induced by the D1-R antagonist, SCH23390, i…

The effects of acute tryptophan depletion on affective behaviour and cognition in Brown Norway and Sprague Dawley rats.

Previous studies in rats and humans have shown that the essential amino acid tryptophan (TRP) is depleted after consumption of a gelatin-based protein-carbohydrate mixture, which is lacking L-tryptophan (TRP-). In rats, TRP depletion caused impaired object recognition but only had a modest effect on affective behaviour. Because these studies were preformed with Wistar rats, the aim of the present experiment was to evaluate strain differences in behavioural responses to acute TRP depletion between Brown Norway (BN) and Sprague Dawley (SD) rats. The rats were repeatedly treated with TRP- or a balanced control (TRP+) and were tested in tests of anxiety- and depression-related behaviour (open-field test, home cage emergence test, social interaction test, forced swim test) and memory. SD rats, but not BNs, showed more anxiety- and depression-related behaviour and impaired object recognition a…

Time-dependent effects of striatal interleukin-2 on open field behaviour in rats.

There is evidence that immune messengers like cytokines can modulate emotional and motivated behaviours and are involved in psychiatric conditions like anxiety, and depression. Previously, we showed that cytokine gene expression (interleukin (IL)-2 mRNA) in specific brain tissues (striatum, prefrontal cortex) correlated with anxiety-like behaviour (open arm time) in an elevated plus-maze in rats. In a subsequent experiment, a single striatal IL-2 injection showed behavioural trends with the lower dose (1 ng) acting in a behavioural suppressive way, whereas the highest dosage (25 ng) led to activation and anxiolytic-like behaviour. Here, to support and extend our previous findings, we tested Wistar outbred rats after a single unilateral (balanced brain sites) IL-2 injection into the ventral/dorsal striatum followed by an open field test acutely and 24 h later. Analyses for horizontal loco…

Induction of IDO by bacille Calmette-Guérin is responsible for development of murine depressive-like behavior.

Chronic inflammation activates the tryptophan-degrading enzyme IDO, which is well known to impair T cell proliferation. We have previously established that bacille Calmette-Guérin (BCG), an attenuated form of Mycobacterium bovis, is associated with persistent activation of IDO in the brain and chronic depressive-like behavior, but a causative role has not been established. In these experiments we used both pharmacologic and genetic approaches to test the hypothesis that IDO activation is responsible for the development of chronic depression that follows BCG infection. BCG induced TNF-alpha, IFN-gamma, and IDO mRNA steady-state transcripts in the brain as well as the enzyme 3-hydroxyanthranilic acid oxygenase (3-HAO) that lies downstream of IDO and generates the neuroactive metabolite, quinolinic acid. Behaviors characteristic of depression were apparent 1 wk after BCG infection. Pretreat…

Chronic delta 9-tetrahydrocannabinol during adolescence provokes sex-dependent changes in the emotional profile in adult rats: behavioral and biochemical correlates.

Few and often contradictory reports exist on the long-term neurobiological consequences of cannabinoid consumption in adolescents. The endocannabinoid system plays an important role during the different stages of brain development as cannabinoids influence the release and action of different neurotransmitters and promote neurogenesis. This study tested whether long-lasting interference by cannabinoids with the developing endogenous cannabinoid system during adolescence caused persistent behavioral alterations in adult rats. Adolescent female and male rats were treated with increasing doses of Delta(9)-tetrahydrocannabinol (THC) for 11 days (postnatal day (PND) 35-45) and left undisturbed until adulthood (PND 75) when behavioral and biochemical assays were carried out. CB1 receptor level and CB1/G-protein coupling were significantly reduced by THC exposure in the amygdala (Amyg), ventral …

Developmental vitamin D deficiency alters adult behaviour in 129/SvJ and C57BL/6J mice.

Developmental vitamin D (DVD) deficiency has been proposed as an environmental risk factor for a number of brain disorders. The absence of this vitamin during foetal development in the rat is known to alter behaviour in the adult, and many of these alterations are informative with respect to the clinical features of schizophrenia. Here we investigated whether DVD deficiency had a similar effect on 129/SvJ and C57BL/6J mice. Female mice were fed a diet deficient in vitamin D for 6 weeks prior to conception until birth, after which dams and their offspring were fed a normal diet (i.e. containing vitamin D). Control mice were fed a normal diet throughout the experiment. The adult offspring underwent a comprehensive behavioural test battery at 10 weeks of age. We found that DVD-deficient mice of both strains exhibited significantly higher levels of exploration, as measured by the frequency o…
