The objective of this study was to evaluate possible side effects of insecticides used in soybean crops on pupae and adults of the egg parasitoid Telenomus podisi Ashmead (Hymenoptera: Platygastridae) under laboratory conditions. The protocol was adapted from standard methodology stablished by the Pesticides and Beneficial Organisms Working Group of the International Organization for Biological and integrated Control (IOBC) for Trichogramma cacoeciae (Marchal) (Hymenoptera: Trichogrammatidae). All tested benzoylureas, diacylhydrazines, diamides and spinosins as well as pyrethroid beta-cyfluthrin were harmless to T...

In order to regenerate the dental pulp, many strategies have been developed as phototherapy. In the pulp repair, we do not know if gallium-aluminum-arsenide (GaAlAs) laser preserves the primary odontoblasts or stimulates the formation of more dentin matrix when dental pulp is damaged. The aim of the present study was to examine the effect of laser phototherapy (λ780 nm) on vascularization, inflammation, density of the primary odontoblast layer, and formation of reactionary and reparative dentin in the dental pulp by provoking extrusion of the rat incisor...

Medications are perceived as health risk factors, because they might cause damage if used improperly. In this context, an adequate assessment of medication use history should be encouraged, especially in transitions of care to avoid unintended medication discrepancies (UMDs). In a case-controlled study, we investigated potential risk factors for UMDs at hospital admission and found that 150 (42%) of the 358 patients evaluated had one or more UMDs. We were surprised to find that there was no record of a patient and/or relative interview on previous use of medication in 117 medical charts of adult patients (44...

Cerebral ischemia-reperfusion is a classical example of reactive oxygen species (ROS) mediated acute damage to brain. Post-ischemic reperfusion induced oxygen free radicals production causes damage to brain cell mitochondria. Antioxidants like quercetin (Qc) have potentials to manage oxidative stress related pathophysiology. However low oral bioavailability and poor cell membrane permeability restricts its therapeutic efficacy. To overcome these hurdles mitochondria specific delivery of Qc nanocapsules were designed to efficiently counteract cerebral ischemia-reperfusion induced cell death and neurodegeneration in young and aged rats...

Inflammation has been identified as an important mediator of seizures and epileptogenesis. Understanding the mechanisms underlying seizure-induced neuroinflammation could lead to the development of novel therapies for the epilepsies. Reactive oxygen species (ROS) are recognized as mediators of seizure-induced neuronal damage and are known to increase in models of epilepsies. ROS are also known to contribute to inflammation in several disease states. We hypothesized that ROS are key modulators of neuroinflammation i...

Neuroinflammation is the inflammation of nervous tissue that can lead to neurodegeneration. Brain-derived neurotrophic factor (BDNF) is a neurotrophin which affects growth, function and survival of neurons, enhances the stabilization of synapses, regulates synaptic function and branching of dendrites and axons. Brain-derived neurotrophic factor is believed to be involved in the pathophysiology of central nervous system (CNS) diseases associated with neuroinflamation. The aim of this study was to investigate new protective and therapeutic effect of acetyl-L-carnitine (ALCAR) in neuroinflammation...

The cardiac transverse (T)-tubule membrane system is the safeguard for cardiac function and undergoes dramatic remodeling in response to cardiac stress. However, the mechanism by which cardiomyocytes repair damaged T-tubule network remains unclear. In the present study, we tested the hypothesis that MG53, a muscle-specific membrane repair protein, antagonizes T-tubule damage to protect against maladaptive remodeling and thereby loss of excitation-contraction coupling and cardiac function. Using MG53-knockout (MG53-KO) mice, we first established that deficiency of MG53 had no impact on maturation of the T-tubule network in developing hearts...

Noninvasive biological readouts of tumor metastatic risk and therapeutic efficacy are needed as healthcare costs rise. Conventional imaging modalities are expensive; require significant periods of time to see appreciable change and repetitive use increases risk of hazardous side effects. Utilizing circulating tumor cells (CTCs) as a minimally invasive biological readout of tumor progression or therapeutic response is increasingly being studied. While focus has primarily been on the predictive value of naturally occurring CTCs, a more recent effort has emerged regarding the potential consequence of therapy induced CTCs...

Activating transcription factor (ATF) 3 regulates chemokine expression in various cell types and tissues. Herein, we studied this regulation in contracting muscle cells in vitro, and in skeletal muscle after muscle-damaging exercise in vivo. C2C12 myotubes with normal or low ATF3 levels (atf3_siRNA) were electrically stimulated (EPS). Also, ATF3-knockout (ATF3-KO) and control mice ran downhill until exhaustion, and muscles were analyzed post-exercise. EPS increased ATF3 levels in myotubes (P < 0.01)...

INTRODUCTION: Infiltration and extravasation account for 23-78 % of the complications stemming from peripheral venous perfusions in neonatal intensive care units. Their consequences, sometimes dramatic, can be pain, infections, or even loss of skin, which can lead to nerve and/or muscle damage, particularly severe for preterm neonates. Today there are no recommendations on the care of these lesions, which can lead to an erroneous choice or to a delay in the possible treatments. OBJECTIVE: This review of the literature aims to explore and propose elements of therapeutic care collected in the scientific literature...

Tendon injuries (tendinopathies) are common in human and equine athletes and characterized by dysregulated collagen matrix, resulting in tendon damage. We have previously demonstrated a functional role for microRNA29a (miR29a) as a post-transcriptional regulator of collagen 3 expression in murine and human tendon injury. Given the translational potential, we designed a randomized, blinded trial to evaluate the potential of a miR29a replacement therapy as a therapeutic option to treat tendinopathy in an equine model that closely mimics human disease...

BACKGROUND: There is still a significant proportion of patients with heart failure who fail to improve after cardiac resynchronization therapy (CRT). The investigators used parametric two-dimensional speckle-tracking echocardiography with polar plots of the amplitude and timing of left ventricular (LV) longitudinal strain to guide implantation of the LV lead, with the aim of increasing CRT response. METHODS: Sixty-four patients who underwent LV lead implantation guided by two-dimensional speckle-tracking echocardiography (study group) and 64 patients treated with standard CRT implantation (control group) were retrospectively analyzed in this study...

This study sought to investigate the effects of kolaviron on diclofenac-induced hepatotoxicity in rats. Sixty male Wistar rats were divided into 6 groups of 10 rats each as follows: a control group that received oral propylene glycol and treatment groups that received diclofenac alone, diclofenac followed by Livolin Forte (a reference drug), or diclofenac followed by kolaviron at three different doses. At the end of the study period, five rats per group were sacrificed under ketamine hydrochloride anesthetic, 24h after treatment, while the other 5 rats in the group were allowed to recover for 2 weeks before being sacrificed...

Concussed individuals have been found to experience balance deficits in the anterior-posterior (AP) direction as indicated by greater Center of Pressure (COP) displacement and velocity. One possible reason for this change in balance control could be due to damage to the lateral vestibulospinal tract which sends signals to control posterior muscles, specifically ankle extensors leading to compensatory torques about the ankle. The purpose of the study was to quantify balance assessments in individuals experiencing persistent post-concussion symptoms (PCS) to determine balance control changes following a vestibular training intervention...

In this review, mucosal immune defense mechanisms used to control infections in the bovine genital tract (vestibule, vagina, cervix, uterus and oviduct) during the postpartum period are reviewed. Knowledge gaps are highlighted to emphasize the need for further investigations. Physical barriers to the entry of microbes include vulvar sealing, vestibule-vaginal constriction, a narrow cervical opening and the mucosal epithelium along with the overlying mucus layer. Genital tract mucosal epithelial cells recognize damage-associated molecular patterns and pathogen-associated molecular patterns and respond by secreting antimicrobial peptides and cytokines to recruit and activate immune cells...

REVIEW
Harold L Atkins, Mark S Freedman
Multiple sclerosis (MS) is thought to be an autoimmune disease targeting the central nervous system leading to demyelination, and axonal and neuronal damage, resulting in progressive disability. More intensive therapies such as immunodepletion with hematopoietic stem-cell rescue are being used at a time prior to patients becoming irreversibly disabled. Over the last 15 years, there has been a shift away from using autologous hematopoietic stem-cell transplants (aHSCT) to treat patients with progressive MS, towards treating those with active inflammation and relapses...

Neoleucinodes elegantalis (Guenée) (Lepidoptera: Crambidae) is one of the major pests of solanaceous plants in South America. It is considered a great threat by the European and Mediterranean Plant Protection Organization due to the serious economic damage that it causes on tomato farms; therefore, controlling this pest is a challenging task in South America. Controlling N. elegantalis at the egg stage is the best way to prevent it from damaging crops; however, thorough studies about the effectiveness of chemicals on the different life stages of this insect pest are lacking...

Inadequate infrastructural networks can be detrimental to society if transport between locations becomes hindered or delayed, especially due to natural hazards which are difficult to control. Thus determining natural hazard susceptible areas and incorporating them in the initial planning process, may reduce infrastructural damages in the long run. The objective of this study was to evaluate the usefulness of expert judgments for assessing natural hazard susceptibility through a spatial multi-criteria analysis approach using hydrological, geological, and land use factors...

Genetically improved farmed tilapia (GIFT, Oreochromis niloticus) are commercially important fish that are cultured in China. GIFT are highly susceptible to diseases when exposed to high temperatures in summer. Better understanding the GIFT regulatory response to heat stress will not only help in determining the relationship between heat stress signalling pathways and adaption mechanisms, but will also contribute to breeding new high-temperature tolerant strains of GIFT. In this study, we built control (28 °C) and heat-treated (37...
