OBJECTIVE: Intracortical brain-machine interfaces (BMIs) are a promising source of prosthesis control signals for individuals with severe motor disabilities. Previous BMI studies have primarily focused on predicting and controlling whole-arm movements; precise control of hand kinematics, however, has not been fully demonstrated. Here, we investigate the continuous decoding of precise finger movements in rhesus macaques. APPROACH: In order to elicit precise and repeatable finger movements, we have developed a novel behavioral task paradigm which requires the subject to acquire virtual fingertip position targets...

Extracellular vesicles (EVs) hold great potential as novel systems for nucleic acid delivery due to their natural composition. Our goal was to load EVs with microRNA that are synthesized by the cells that produce the EVs. HEK293T cells were engineered to produce EVs expressing a lysosomal associated membrane, Lamp2a fusion protein. The gene encoding pre-miR-199a was inserted into an artificial intron of the Lamp2a fusion protein. The TAT peptide/HIV-1 transactivation response (TAR) RNA interacting peptide was exploited to enhance the EV loading of the pre-miR-199a containing a modified TAR RNA loop...

HIV-associated neurocognitive disorder (HAND) affects approximately half of HIV-infected patients. Loss of synaptic connections is a hallmark of many neurocognitive disorders, including HAND. The HIV-1 protein transactivator of transcription (Tat) disrupts synaptic connections both in vitro and in vivo and has been linked to impaired neurocognitive function in humans. In vitro studies have shown that ifenprodil, an antagonist selective for GluN2B-containing NMDARs, reverses synapse loss when applied after Tat...

BACKGROUND: Methadone maintenance treatment (MMT) patients face unique costs associated with their healthcare expenditures. As such, it is important that these patients have access to health insurance (HI) to help them pay for both routine and unforeseen health services. In this study, we explored factors related to health insurance enrollment and utilization among MMT patients, to move Vietnam closer to universal coverage among this patient population. METHODS: A cross-sectional study was conducted with 1003 patients enrolled in MMT in five clinics in Hanoi and Nam Dinh provinces...

Although potent combination antiretroviral therapy can effectively block viral replication in the host, human immunodeficiency virus (HIV) persists due to the existence of latent but replication-competent proviruses residing primarily in a very small population of resting memory CD4(+) T cells. Viral latency is established when the expression of the autoregulatory viral trans-activating factor Tat is reduced to subthreshold levels. The absence of Tat reduces HIV transcription and protein production to levels that make the host cell invisible to the immune system and refractory to antiretroviral treatment...

Post‑translational modifications have been associated with developmental and aging processes, as well as in the pathogenesis of certain diseases. The present study aimed to investigate the effects of small ubiquitin‑like modifier 1 (SUMO‑1) on hippocampal dependent memory function, cell proliferation and neuroblast differentiation. To facilitate the delivery of SUMO‑1 into hippocampal neurons, a transactivator of transcription (Tat)‑SUMO‑1 fusion protein was constructed and mice were divided into two groups: A vehicle (Tat peptide)‑treated group and a Tat‑SUMO‑1‑treated group...

Connexin43 (CX43), a protein that forms gap junction channels and hemichannels in astrocytes, is downregulated in high-grade gliomas. Its relevance for glioma therapy has been thoroughly explored; however, its positive effects on proliferation are counterbalanced by its effects on migration and invasion. Here, we show that a cell-penetrating peptide based on CX43 (TAT-Cx43266-283) inhibited c-Src and focal adhesion kinase (FAK) and upregulated phosphatase and tensin homolog in glioma stem cells (GSCs) derived from patients...

BACKGROUND: Our health system orders a high number of STAT priority portable chest radiographs (62%) compared to Routine (35%) and Today (3%). Retrospective chart review of 1000 chest radiographs ordered with the STAT priority revealed that 38% of studies did not indicate clinical urgency. Given the high number or STAT priority portable chest radiographs ordered, prioritizing acquisition and interpretation of true STATs has become challenging for technologists and radiologists, leading to process inefficiencies, long turnaround times (TATs), communication failures, and patient-safety errors...

Aging is associated with impaired renal artery function, which is partly characterized by arterial stiffening and a reduced vasodilatory capacity due to excessive generation of reactive oxygen species by NADPH oxidases (Nox). The abundance and activity of Nox depends on basal activity of the heptahelical transmembrane receptor GPER; however, whether GPER contributes to age-dependent functional changes in renal arteries is unknown. This study investigated the effect of aging and Nox activity on renal artery tone in wild-type and GPER-deficient (Gper-/-) mice (4 and 24 months old)...

The connection between the repression of human immunodeficiency virus type 1(HIV-1) transcription and the resting CD4+ T cell state suggests that the host transcription factors involved in the active maintenance of lymphocyte quiescence are likely to repress the viral transactivator, Tat, thereby restricting HIV-1 transcription. In this study, we analysed the interplay between Tat and the forkhead box transcription factors, FoxO1 and FoxO4. We show that FoxO1 and FoxO4 antagonize Tat-mediated transactivation of HIV-1 promoter through the repression of Tat protein expression...

The blood-brain barrier (BBB) is the protective parclose of brain safety, but it is also the main obstacle of the drug delivery to cerebral parenchyma, which hamper therapy for brain diseases. In this work, a glioma targeted drug delivery system was developed through loading doxorubicin into Angiopep-2 and TAT peptide dual-modified liposomes (DOX-TAT-Ang-LIP). Low-density lipoprotein receptor-related protein-1 (LRP1) was one receptor overexpressed on both BBB and glioma cytomembranes. Angiopep-2, a specific ligand of LRP1, exhibited high LRP1 binding efficiency...

Human immunodeficiency virus type (HIV) transcription is crucial for its life cycle and is primarily involved in the maintenance of viral latency. HIV transcription is regulated by both viral and cellular transcription factors. Numerous epigenetic factors, as well as transcriptional suppressor proteins, play major roles in the maintenance of transcriptional silencing of viral gene expression from the proviral DNA. Once inducible transcription factors such as nuclear factor B are activated through extracellular signaling, viral latency is terminated and transcription from the silenced proviral DNA is initiated...

Xanthomonas oryzae pv. oryzae, an economically important bacterium, causes a serious disease in rice production worldwide called bacterial leaf blight. How X. oryzae pv. oryzae infects rice and causes symptoms remains incompletely understood. Our earlier works demonstrated that the twin-arginine translocation (Tat) pathway plays an vital role in X. oryzae pv. oryzae fitness and virulence but the underlying mechanism is unknown. In this study, we used strain PXO99(A) as a working model, and identified 15 potential Tat-dependent translocation proteins (TDTP) by using comparative proteomics and bioinformatics analyses...
