Rhinoceros (rhino) numbers have dwindled substantially over the past century. As a result, three of the five species are now considered to be critically endangered, one species is vulnerable and one species is near-threatened. Poaching has increased dramatically over the past decade due to a growing demand for rhino horn products, primarily in Asia. Improved wildlife forensic techniques, such as validated tests for species identification of seized horns, are critical to aid current enforcement and prosecution efforts and provide a deterrent to future rhino horn trafficking...

Pregnancy is a well-established risk factor for venous thromboembolism and is associated with a state of hypercoagulability. The use of sensitive and specific biological markers to predict risk factors for thrombosis is essential during pregnancy. Our objective was to investigate the usefulness of thrombin generation test (TGT) as a marker to predict the risk of thrombosis in high risk venous thrombosis (HRVT) pregnancies compared to normal pregnancies. This retrospective study enrolled 134 women with HRVT pregnancies, 78 of whom had monozygotic, spontaneous and untreated pregnancies and formed the study group...

Achieving minimal residual mitral regurgitation (MR) after percutaneous MitraClip repair is limited by iatrogenic mitral stenosis. It is unknown whether allowing moderately elevated postprocedural mean mitral gradients (MMGs) to achieve < moderate residual MR is preferable to moderate residual regurgitation. Patients with less-than-moderate residual MR but a MMG of ≥5 mm Hg (Group 1) were compared with patients with moderate residual MR (Group 2). The primary end point was heart failure hospitalization...

Visceral adipose tissue (VAT) is a metabolically active organ, associated with higher risk of malignancies. We aimed to evaluate if VAT is associated with the risk of hepatocellular carcinoma (HCC) in patients presenting with cirrhosis as well as HCC recurrence after liver transplantation (LT). Cirrhotic patients (n=678; 457 males) who were assessed for LT (289 with HCC) were evaluated for body composition analysis. Patients who underwent LT (n=247, 168 males) were subsequently evaluated for body composition, and 96 of these patients (78 males) had HCC...

The genetic characterization and actual prevalence of EIAV in Mongolian horse in the disease endemic region is currently unknown. Here, 11 of 776 horse serum samples from four Mongolian provinces tested positive on agar gel immunodiffusion test. Genomic DNA extracted from all seropositive samples was subjected to nested PCR assay. Among these, three samples tested positive with nested PCR assay and were identified by sequencing analysis based on long termination repeat and tat gene of the virus. Two of the three sequences were identical, with 94...

Sepsis concurrently activate both coagulation and complement systems. While complement activation by bacteria is well-documented, work in mice and in vitro suggests that coagulation proteases can directly cleave complement proteins. We aimed to determine if generation of coagulation proteases in vivo can activate the complement cascade in two highly coagulopathic models. We compared temporal changes in activation biomarkers of coagulation (thrombin-antithrombin, TAT), fibrinolysis (plasmin-antiplasmin, PAP) and complement (C3b, C5a, C5b-9) in baboons infused with factor Xa and phospholipids (FXa/PCPS) vs...

BACKGROUND: Laboratory-based respiratory pathogen (RP) results are often available too late to influence clinical decisions such as hospitalisation or antibiotic treatment due to time delay in transport of specimens and testing schedules. Ward-based i.e. point of care (POC) testing providing rapid results may alter the clinical management pathway. METHODS: FilmArray® RP polymerase chain reaction (PCR) systems were placed in three in-patient and out-patient medical areas...

Although tumor-targeting nanovehicles for hepatocellular carcinoma (HCC) chemotherapy have attracted great research and clinic interest, the poor cancer penetration, inefficient cellular uptake, and slow intracellular drug release greatly compromise their therapeutic outcomes. In this work, a multifunctional mixed micellar system, consisting of glycyrrhetinic acid (GA) for specific liver-targeting, trans-activator of transcription (TAT) peptide for potent cell penetration, and pH-sensitive poly(β-amino ester) polymers for acidic-triggered drug release, was developed to provide HCC-targeting delivery and pH-triggered release of doxorubicin (DOX)...

Type 1 diabetes (T1D) is characterized by massive destruction of insulin-producing β cells by autoreactive T lymphocytes, arising via defective immune tolerance. Therefore, effective anti-T1D therapeutics should combine autoimmunity-preventing and insulin production-restoring properties. We constructed a cell-permeable PDX1-FOXP3-TAT fusion protein (FP) composed of two transcription factors: forkhead box P3 (FOXP3), the master regulator of differentiation and functioning of self-tolerance-promoting Tregs, and pancreatic duodenal homeobox-1 (PDX1), the crucial factor supporting β cell development and maintenance...

A20 (also known as TNFAIP3) is a potent anti-inflammatory protein that suppresses many intracellular signaling pathways induced by inflammatory cytokines and bacterial and viral pathogens. The anti-inflammatory function of A20 depends on its modulation of or binding to polyubiquitin chains on key signaling proteins in the nuclear factor-κB (NF-κB) pathway. To test whether A20 can be used as therapeutic agent in these inflammatory diseases, we prepared a recombinant cell-penetrating form of A20 (TAT-A20) for intracellular delivery and examined its effect on tumor necrosis factor-α (TNFα)-induced NF-κB activation...

HIV-associated neurocognitive disorder (HAND) remains highly prevalent in HIV infected individuals and represents a special group of neuropathological disorders, which are associated with HIV-1 viral proteins, such as transactivator of transcription (Tat) protein. Cocaine abuse increases the incidence of HAND and exacerbates its severity by enhancing viral replication. Perturbation of dopaminergic transmission has been implicated as a risk determinant of HAND. The presynaptic dopamine (DA) transporter (DAT) is essential for DA homeostasis and dopaminergic modulation of the brain function including cognition...

Amphetamine (AMPH)-mediated norepinephrine transporter (NET) downregulation requires NET-T258/S259 trafficking motif. The present study utilizes cell permeable NET-T258/S259 motif interfering peptide, which blocks AMPH-induced NET downregulation, to explore the role of this form of NET regulation in AMPH-mediated behaviors. In rats receiving intra-accumbal microinjections of TAT-conjugated peptides encompassing NET-T258/S259 motif, acute systemic AMPH failed to inhibit NE transport in the TAT-NET-T258/S259 wild-type (WT) peptide injected hemisphere but not in the vehicle or scrambled peptide injected hemisphere...

In the present study, we searched for possible candidates that can prevent ischemic damage in the rabbit spinal cord. For this study, we used two-dimensional gel electrophoresis followed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry, in sham- and ischemia-operated animals. As the level of protein disulfide-isomerase A3 (PDIA3) significantly decreased 3 h after ischemia/reperfusion, we further investigated its possible role against ischemic damage using an in vitro spinal cord cell line and in vivo spinal cord ischemic model...

Friedreich ataxia (FA) is a rare disease caused by deficiency of frataxin, a mitochondrial protein. As there is no cure available for this disease, many strategies have been developed to reduce the deleterious effects of such deficiency. One of these approaches is based on delivering frataxin to the tissues by coupling the protein to trans-activator of transcription (TAT) peptides, which enables cell membranes crossing. In this study, we tested the efficiency of TAT-MTScs-FXN fusion protein to decrease neurodegeneration markers on frataxin-depleted neurons obtained from dorsal root ganglia (DRG), one of the most affected tissues...

It is widely accepted that endocytosis mediates the uptake of cationic cell penetrating peptides (CPPs) at relatively low concentrations (i.e. nano- to micromolar), while direct transduction across the plasma membrane comes into play at higher concentrations (i.e. micro- to millimolar). This latter process appears to depend on peptide-driven cellular processes, which in turn may induce local perturbations of plasma-membrane composition and/or integrity, and to be favored by peptide aggregation, especially into dimers...
