Chemical conspicuousness, ant organs, and specificity in myrmecophilous caterpillars partitioning ant-plant systems.

Resource partitioning among sympatric species is crucial for assembling ecological communities, such as caterpillar-ant assemblages in tropical forests. Myrmecophilous caterpillars use behavioral and chemical strategies to coexist with ants, avoiding attacks. While these strategies are well-understood in single pair of interacting species, such as those involving myrmecophiles and ants, their role in complex multitrophic interactions that include several species of plants, herbivores and ants remains unclear.

Influence of Host Plants and Tending Ants on the Cuticular Hydrocarbon Profile of a Generalist Myrmecophilous Caterpillar.

In myrmecophilous organisms, which live in symbiosis with ants, cuticular hydrocarbons (CHCs) play a pivotal role in interspecific communication and defense against chemical-oriented predators. Although these interactions form complex information webs, little is known about the influence of biotic environmental factors on the CHC profiles of myrmecophiles. Here, we analyzed the effect of different host plants and tending ants on the larval CHC profile of Synargis calyce (Lepidoptera: Riodinidae), a polyphagous species with facultative myrmecophily.

Long-Term Clinical Outcome of Abdomino-Thoracic Lymphatic Interventions of Traumatic and Non-Traumatic Lymphatic Leakage in Adults.

The aim of this study was to retrospectively evaluate the long-term results of lymphatic interventions in adults with abdomino-thoracic lymphatic pathologies. Management of abdomino-thoracic chylous effusions in adults undergoing X-ray-lymphangiography with or without lymph-vessel embolization (LVE) from 2010-2018 was reviewed. Patients underwent lymphangiography alone when imaging showed normal findings or lymphatic obstruction without leakage or reflux; otherwise, LVE was performed (leakage, reflux, obstruction with leakage or reflux, lymphatic masses).

T cells expressing multiple co-inhibitory molecules in acute malaria are not exhausted but exert a suppressive function in mice.

Overwhelming activation of T cells in acute malaria is associated with severe outcomes. Thus, counter-regulation by anti-inflammatory mechanisms is indispensable for an optimal resolution of disease. Using Plasmodium berghei ANKA (PbA) infection of C57BL/6 mice, we performed a comprehensive analysis of co-inhibitory molecules expressed on CD4 and CD8 T cells using an unbiased cluster analysis approach.

A new ant-butterfly symbiosis in the forest canopy fills an evolutionary gap.

Myrmecophilous butterflies can establish complex symbiotic relationships with ants. A caterpillar wandering among the brood of the aggressive ponerine ant Neoponera villosa was found inside the core of a nest built in the myrmecophytic bromeliad Aechmea bracteata. This is the first caterpillar found living inside a ponerine ant nest.

The Building Regulation in Dual-Generations Program (BRIDGE): A Mixed-Methods Feasibility Pilot of a Parenting Program for Depressed Mothers of Preschoolers, Matched with Dialectical Behavior Therapy Skills.

Early exposure to maternal depression is a key risk factor for child mental illness (MI), but there are limited programs that interrupt intergenerational transmission. The BRIDGE "Building Regulation in Dual Generations" Program treats maternal MI using Dialectical Behavior Therapy Skills with a paired curriculum that promotes non-reactive and emotionally validating parenting designed to improve child mental health and ultimately prevent MI. The pilot feasibility trial (n = 28 dyads) included mothers and their preschool-aged children.

Motor Imagery Training of Reaching-to-Grasp Movement Supplemented by a Virtual Environment in an Individual With Congenital Bilateral Transverse Upper-Limb Deficiency.

This study explored the effect of kinesthetic motor imagery training on reaching-to-grasp movement supplemented by a virtual environment in a patient with congenital bilateral transverse upper-limb deficiency. Based on a theoretical assumption, it is possible to conduct such training in this patient. The aim of this study was to evaluate whether cortical activity related to motor imagery of reaching and motor imagery of grasping of the right upper limb was changed by computer-aided imagery training (CAIT) in a patient who was born without upper limbs compared to a healthy control subject, as characterized by multi-channel electroencephalography (EEG) signals recorded before and 4, 8, and 12 weeks after CAIT.

Cytotoxic T Cell-Derived Granzyme B Is Increased in Severe Malaria.

In malaria, CD8 T cells play a double-edged role. Liver-stage specific CD8 T cells can confer protection, as has been shown in several vaccine studies. Blood-stage specific CD8 T cells, on the other hand, contribute to the development of cerebral malaria in murine models of malaria.

PGC1α Inhibits Polyamine Synthesis to Suppress Prostate Cancer Aggressiveness.

Although tumorigenesis is dependent on the reprogramming of cellular metabolism, the metabolic pathways engaged in the formation of metastases remain largely unknown. The transcriptional coactivator peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC1α) plays a pleiotropic role in the control of cancer cell metabolism and has been associated with a good prognosis in prostate cancer. Here, we show that PGC1α represses the metastatic properties of prostate cancer cells via modulation of the polyamine biosynthesis pathway.

Irreducible ankle fracture dislocation due to posterior tibialis tendon interposition: Diagnostic and clues for early management - A case report.

Irreducible fracture dislocation of the ankle is a rare condition. Multiple cases have been described throughout the literature. Different known etiologies involve the distal fibula, deltoïd ligament and tendons of the posteromedial malleolar region.

The metabolic modulator PGC-1α in cancer.

The peroxisome proliferator-activated receptor gamma coactivator 1 alpha (PGC-1α) is a central modulator of cell metabolism. It regulates mitochondrial biogenesis and oxidative metabolism. Modifications and adaptations in cellular metabolism are hallmarks of cancer cells, thus, it is not surprising that PGC-1α plays a role in cancer.

UBTD1 is a mechano-regulator controlling cancer aggressiveness.

Ubiquitin domain-containing protein 1 (UBTD1) is highly evolutionary conserved and has been described to interact with E2 enzymes of the ubiquitin-proteasome system. However, its biological role and the functional significance of this interaction remain largely unknown. Here, we demonstrate that depletion of UBTD1 drastically affects the mechanical properties of epithelial cancer cells via RhoA activation and strongly promotes their aggressiveness.
