X-linked Inhibitor of Apoptosis (XIAP) deficiency predisposes people to pathogen-associated hyperinflammation. Upon XIAP loss, Toll-like receptor (TLR) ligation triggers RIPK3-caspase-8-mediated IL-1β activation and death in myeloid cells. How XIAP suppresses these events remains unclear. Here, we show that TLR-MyD88 causes the proteasomal degradation of the related IAP, cIAP1, and its adaptor, TRAF2, by inducing TNF and TNF Receptor 2 (TNFR2) signaling. Genetically, we define that myeloid-specific cIAP1 loss promotes TLR-induced RIPK3-caspase-8 and IL-1β activity in the absence of XIAP...

INTRODUCTION: Emotion dysregulation (ED) has long been recognized in clinical descriptions of attention-deficit hyperactivity disorder (ADHD), but a renewed interest in ED has advanced research on the overlap between the two entities. Autonomic reactivity (AR) is a neurobiological correlate of emotion regulation; however, the association between ADHD and AR remains unclear. Our aim was to explore the clinical differences, AR, and subjective emotional responses to visual emotional stimuli in ADHD children with and without ED...

We applied the use of thermography to cognitive neuropsychology, particularly as an objective marker of subjective experiences, in the context of lying. We conducted three experiments: (a) An important lie was invented by the participants in 3 min, and it was recounted by phone to a significant person while they were recorded by the thermographic camera, obtaining a face and hands map of the lie. (b) A similar methodology was carried out, but adding the Cold Stress Test (CST) of the dominant hand during the phone call, obtaining a second physiologic marker (the percentage of thermal recovery) to detect the lie...

2,5-Dihydroxyacetophenone (DHAP) is an active compound obtained from Radix rehmanniae preparata, which is widely used as a herbal medicine in many Asian countries. DHAP has been found to possess anti-inflammatory, anti-anxiety, and neuroprotective qualities. For the present study, we evaluated the anti-cancer effects of DHAP on multiple myeloma cells. It was discovered that DHAP downregulated the expression of oncogenic gene products like Bcl-xl, Bcl-2, Mcl-1, Survivin, Cyclin D1, IAP-1, Cyclin E, COX-2, and MMP-9, and upregulated the expression of Bax and p21 proteins, consistent with the induction of G2/M phase cell cycle arrest and apoptosis in U266 cells...

INTRODUCTION: Abdomen, a closed compartment, is prone to raised intra-abdominal pressure (IAP) in the postoperative period. After a critical value of ≥ 15 cm of water, IAP produces abdominal compartment syndrome (ACS). ACS leads to reduced venous return, reduced cardiac output, and domino effect of organ dysfunction, leading to death. Hence, it is the need of hour to monitor IAP to pick up intra-abdominal hypertension (IAH) and ACS. This routine facilitates early institution of treatment measures...

Epigallocatechin-3-gallate (EGCG), a polyphenol in green tea is an effective antioxidant and possesses neuroprotective effects. For neurogenesis and synaptic plasticity, brain-derived neurotrophic factor (BDNF) and cyclic AMP response element-binding protein (CREB) are crucially involved. In this study we aimed to assess protective effects of EGCG against sevoflurane-induced neurotoxicity in neonatal mice. Distinct groups of C57BL/6 mice were given EGCG (25, 50 or 75 mg/kg b.wt) from postnatal day 3 (P3) to P21 and were subjected to sevoflurane (3 %; 6 h) exposure on P7...

BACKGROUND: Early-onset neonatal sepsis (EOS) is a serious and potentially life-threatening disease in newborns. C reactive protein (CRP) is the most used laboratory biomarker for the detection of EOS. Little is known about normal reference values of CRP during the perinatal period as several factors are able to influence it. OBJECTIVES: To identify an appropriate range of CRP values in healthy term newborns during the first 48 hours of life. DESIGN: CRP determination was performed in 859 term newborns at 12, 24 and 48 hours of life...

Transposon reactivation is an inherent danger in cells that lose epigenetic silencing during developmental reprogramming. In the mouse, long terminal repeat (LTR)-retrotransposons, or endogenous retroviruses (ERV), account for most novel insertions and are expressed in the absence of histone H3 lysine 9 trimethylation in preimplantation stem cells. We found abundant 18 nt tRNA-derived small RNA (tRF) in these cells and ubiquitously expressed 22 nt tRFs that include the 3' terminal CCA of mature tRNAs and target the tRNA primer binding site (PBS) essential for ERV reverse transcription...

Smac-mimetics are emerging as promising anti-cancer agents and are being evaluated in clinical trials for a variety of malignancies. Smac-mimetics can induce TNF production from a subset of tumor cells and simultaneously sensitize them to TNF-induced apoptosis. However, TNF derived from other cellular sources, such as cytotoxic lymphocytes (CLs) within the tumor, may also contribute to the anti-tumor activity of SMs. Here, we show that CD8(+) T cells and NK cells potently kill tumor cells in the presence of the SM, birinapant...

Inhibitor of Apoptosis Proteins (IAPs) are critical regulators of cell death and survival pathways. Mice lacking cellular IAP (cIAP) 1 and either cIAP2 or X-linked IAP (XIAP) die in utero, and myeloid lineage-specific deletion of all IAPs causes sterile inflammation, but their role in the skin is unknown. We generated epidermal-specific IAPs deficient mice and found that combined genetic deletion of cIAP1 in keratinocytes and ubiquitous cIAP2 deletion (cIap1(EKO/EKO).cIap2(-/-)) caused profound skin inflammation and keratinocyte death, lethal by post-partum day 10...

BACKGROUND: Schizophrenia is a neurological disease characterized by alterations to patients' cognitive functions and emotional expressions. Relevant studies often use magnetic resonance imaging (MRI) of the brain to explore structural differences and responsiveness within brain regions. However, as this technique is expensive and commonly induces claustrophobia, it is frequently refused by patients. Thus, this study used non-contact infrared thermal facial images (ITFIs) to analyze facial temperature changes evoked by different emotions in moderately and markedly ill schizophrenia patients...
