Regional changes of maximum dose insecticide responses in diamondback moth (Lepidoptera: Plutellidae) populations from Georgia and Florida, USA.

Maximum dose bioassays were conducted to assess the efficacy of multiple registered active ingredients for diamondback moth (DBM), Plutella xylostella (L.), control in Georgia and Florida from 2021 to 2023 as a follow-up to an earlier study. Low efficacy (<40% mortality) was recorded for the highest labeled rate of Bacillus thuringiensis var.

Anopheles gambiae strain (Ag55) cultured cells originated from Anopheles coluzzii and are phagocytic with hemocyte-like gene expression.

Anopheles gambiae and Anopheles coluzzii are closely related species that are predominant vectors of malaria in Africa. Recently, A. gambiae form M was renamed A.

A Target Site Mutation Associated With Diamide Insecticide Resistance in the Diamondback Moth Plutella xylostella (Lepidoptera: Plutellidae) is Widespread in South Georgia and Florida Populations.

Laboratory colonies of diamondback moth (DBM) larvae were established from larvae collected from four sites in Georgia and Florida where diamide, specifically chlorantraniliprole, insecticide resistance was recently documented. Based on dose-response experiments, these colonies exhibited 109- to 4,298-fold resistance to chlorantraniliprole, compared to a commercially available susceptible control colony. Colonies exhibited 50- to 107-fold resistance to another diamide, cyantraniliprole, based on similar dose-response experiments.

Defense-Related Gene Expression Following an Orthotospovirus Infection Is Influenced by Host Resistance in .

Planting resistant cultivars is the most effective tactic to manage the thrips-transmitted tomato spotted wilt orthotospovirus (TSWV) in peanut plants. However, molecular mechanisms conferring resistance to TSWV in resistant cultivars are unknown. In this study, transcriptomes of TSWV-susceptible (SunOleic 97R) and field-resistant (Tifguard) peanut cultivars with and without TSWV infection were assembled and differentially expressed genes (DEGs) were compared.

Regional Survey of Diamondback Moth (Lepidoptera: Plutellidae) Response to Maximum Dosages of Insecticides in Georgia and Florida.

We conducted maximum dose bioassays of insecticide for the control of diamondback moth (DBM), Plutella xylostella (Linnaeus), in cole crops, from 2016 to 2019 at several commercial locations in Georgia and Florida. The nominal maximum dose was defined as the highest labeled rate of an insecticide at the beginning of the survey in the equivalent of 935 liters/ha dilution. The results indicated low insecticide efficacy for high labeled rates of the following insecticides by common name (Insecticide Resistance Action Committee group number in parentheses).

Red blood cell metabolism in Rhesus macaques and humans: comparative biology of blood storage.

Macaques are emerging as a critical animal model in transfusion medicine, because of their evolutionary similarity to humans and perceived utility in discovery and translational science. However, little is known about the metabolism of Rhesus macaque red blood cells (RBC) and how this compares to human RBC metabolism under standard blood banking conditions. Metabolomic and lipidomic analyses, and tracing experiments with [1,2,3-C]glucose, were performed using fresh and stored RBC (sampled weekly until storage day 42) obtained from Rhesus macaques (n=20) and healthy human volunteers (n=21).

miR-873-5p targets mitochondrial GNMT-Complex II interface contributing to non-alcoholic fatty liver disease.

Objective: Non-alcoholic fatty liver disease (NAFLD) is a complex pathology in which several dysfunctions, including alterations in metabolic pathways, mitochondrial functionality and unbalanced lipid import/export, lead to lipid accumulation and progression to inflammation and fibrosis. The enzyme glycine N-methyltransferase (GNMT), the most important enzyme implicated in S-adenosylmethionine catabolism in the liver, is downregulated during NAFLD progression. We have studied the mechanism involved in GNMT downregulation by its repressor microRNA miR-873-5p and the metabolic pathways affected in NAFLD as well as the benefit of recovery GNMT expression.

Comparison of transcriptomes of an orthotospovirus vector and non-vector thrips species.

Thrips transmit one of the most devastating plant viruses worldwide-tomato spotted wilt tospovirus (TSWV). Tomato spotted wilt tospovirus is a type species in the genus Orthotospovirus and family Tospoviridae. Although there are more than 7,000 thrips species, only nine thrips species are known to transmit TSWV.

Sonoporation as an Approach for siRNA delivery into T cells.

Delivery of small interfering RNAs (siRNAs) into primary T cells is quite challenging because they are non-proliferating cells and are difficult to transfect with non-viral approaches. Because sonoporation is independent of the proliferation status of cells and siRNA acts in the cell cytoplasm, we investigated whether sonoporation could be used to deliver siRNA into mouse and human T cells. Cells mixed with Definity microbubbles and siRNA were sonicated with a non-focused transducer of center frequency 2.

Reducing Dental Plaque Scores in Long-term Care Facilities Using a Checklist and Random Inspections: A Pilot Study.

The development and use of tailored interventions in overcoming barriers to optimum health in long-term care facility residents is of the highest importance. One successful approach to improving health outcomes is the use of a checklist by health care providers. Despite the evidence of the success of such checklists in nursing and medicine, there is little evidence on their use in improving dental outcomes.

Parabiosis Incompletely Reverses Aging-Induced Metabolic Changes and Oxidant Stress in Mouse Red Blood Cells.

Mature red blood cells (RBCs) not only account for ~83% of the total host cells in the human body, but they are also exposed to all body tissues during their circulation in the bloodstream. In addition, RBCs are devoid of de novo protein synthesis capacity and, as such, they represent a perfect model to investigate system-wide alterations of cellular metabolism in the context of aging and age-related oxidant stress without the confounding factor of gene expression. In the present study, we employed ultra-high-pressure liquid chromatography coupled with mass spectrometry (UHPLC-MS)-based metabolomics and proteomics to investigate RBC metabolism across age in male mice (6, 15, and 25 months old).

Transcriptome changes associated with Tomato spotted wilt virus infection in various life stages of its thrips vector, Frankliniella fusca (Hinds).

Persistent propagative viruses maintain intricate interactions with their arthropod vectors. In this study, we investigated the transcriptome-level responses associated with a persistent propagative phytovirus infection in various life stages of its vector using an Illumina HiSeq sequencing platform. The pathosystem components included a Tospovirus, Tomato spotted wilt virus (TSWV), its insect vector, Frankliniella fusca (Hinds), and a plant host, Arachis hypogaea (L.

Deficiency of mitochondrial modulator MCJ promotes chemoresistance in breast cancer.

Despite major advances in early detection and prognosis, chemotherapy resistance is a major hurdle in the battle against breast cancer. Identifying predictive markers and understanding the mechanisms are key steps to overcoming chemoresistance. Methylation-controlled J protein (MCJ, also known as DNAJC15) is a negative regulator of mitochondrial respiration and has been associated with chemotherapeutic drug sensitivity in cancer cell lines.

Fine-Tuning of CD8(+) T Cell Mitochondrial Metabolism by the Respiratory Chain Repressor MCJ Dictates Protection to Influenza Virus.

Mitochondrial respiration is regulated in CD8(+) T cells during the transition from naive to effector and memory cells, but mechanisms controlling this process have not been defined. Here we show that MCJ (methylation-controlled J protein) acted as an endogenous break for mitochondrial respiration in CD8(+) T cells by interfering with the formation of electron transport chain respiratory supercomplexes. Metabolic profiling revealed enhanced mitochondrial metabolism in MCJ-deficient CD8(+) T cells.

Effect of Hippotherapy on Motor Proficiency and Function in Children with Cerebral Palsy Who Walk.

Aims: To evaluate the effects of hippotherapy on physical capacities of children with cerebral palsy.

Methods: Thirteen children (4-12 years old) with cerebral palsy classified in Gross Motor Function Classification System Level I or II were included in this prospective quasi-experimental ABA design study. Participants received 10 weeks of hippotherapy (30 min per week).

Long-lasting effects of dexamethasone on immune cells and wound healing in the zebrafish.

This study assessed the lasting impact of dexamethasone (DEX) exposure during early development on tissue repair capacity at later life stages (5, 14, and 24 days post fertilization [dpf]) in zebrafish larvae. Using the caudal fin amputation model, we show that prior exposure to DEX significantly delays but does not prevent wound healing at all life stages studied. DEX-induced impairments on wound healing were fully restored to normal levels with longer post amputation recovery time.

Updating in working memory predicts greater emotion reactivity to and facilitated recovery from negative emotion-eliciting stimuli.

That emotions change in response to emotion-eliciting events is a natural part of human life. However, it is equally important for emotions to return to baseline once the emotion-eliciting events have passed. This suggests that the ability to emotionally react to and recover from emotion-eliciting events is critical for healthy psychological functioning.

Emotional inertia and external events: The roles of exposure, reactivity, and recovery.

Increased moment-to-moment predictability, or inertia, of negative affect has been identified as an important dynamic marker of psychological maladjustment, and increased vulnerability to depression in particular. However, little is known about the processes underlying emotional inertia. The current article examines how the emotional context, and people's responses to it, are related to emotional inertia.

Effect of acute stresses on zebra fish (Danio rerio) metabolome measured by NMR-based metabolomics.

We applied an acute stress model to zebra fish in order to measure the changes in the metabolome due to biological stress. This was done by submitting the fish to fifteen minutes of acute confinement (netting) stress, and then five minutes for the open field and light/dark field tests. A polar extract of the zebra fish was then subjected to (1)H nuclear magnetic spectroscopy.

Illegitimate V(D)J recombination-mediated deletions in Notch1 and Bcl11b are not sufficient for extensive clonal expansion and show minimal age or sex bias in frequency or junctional processing.

Illegitimate V(D)J recombination at oncogenes and tumor suppressor genes is implicated in formation of several T cell malignancies. Notch1 and Bcl11b, genes involved in developing T cell specification, selection, proliferation, and survival, were previously shown to contain hotspots for deletional illegitimate V(D)J recombination associated with radiation-induced thymic lymphoma. Interestingly, these deletions were also observed in wild-type animals.
