Mitochondrial neurogastrointestinal encephalopathy (MNGIE) is a rare, inherited, multisystemic autosomal recessive disorder caused by mutations in the nuclear TYMP gene. This syndrome is characterized by ptosis, external ophthalmoplegia, gastrointestinal dysmotility, cachexia, peripheral neuropathy, and leukoencephalopathy. Our case illustrates a patient diagnosed with MNGIE and cachexia who has benefited from the initiation and maintenance of parenteral nutrition. We highlight the benefits of receiving long-term supplementary home parenteral nutrition under close monitoring for patients with this neurogastrointestinal disease in order to gain weight and maintain good health.
Obstetric anal sphincter injuries (OASI) are a common preventable cause of anal incontinence. Both diagnosis and primary repair are often sub- optimal, partly due to the absence of effective clinical audit. This study was designed to evaluate the location of scars diagnosed by translabial ultrasound (TLUS).

This was a retrospective analysis of 309 women following primary repair of OASI between June 2012 and May 2019. All underwent a standardized interview, including St Mark's incontinence score (SMIS), clinical examination and TLUS assessment. TAK-243 E1 Activating inhibitor Analysis of TLUS volume data sets was undertaken by postprocessing, blinded against all other information. We classified tears into four groups A no visible defect or distortion (potential false-positive), B exclusively proximal OASI, C exclusively distal OASI; D both proximal and distal OASI.

Of the 309 women seen, we excluded 34 women referred for reasons other than recent (< 1 year) OASI, 16 due to missing data and 4 due to poor image quality, leaving 255 patients. Women were seen on average 0.25 years (SD 0.1) after the index birth and mean age was 29.1 years (SD, 4.6). Anal incontinence was reported by 97 (38.7%). The EAS was scarred proximally (Group B) in 64 (25 %) women in 19 (7%) the trauma was distal (Group C). In 165 (65 %), the damage affected both proximal and distal EAS.

EAS scars after primary repair commonly affect the entire length of the EAS. However, partial tears seem to be more likely to occur proximally. This article is protected by copyright. All rights reserved.

Autoimmune diseases are a heterogeneous group of diseases which lose the immunological tolerance to self-antigens. It is well recognized that irregularly provoked T cells participate in the pathological immune responses. As a novel nanomaterial with promising applications, tetrahedral framework nucleic acid (TFNA) nanostructure was found to have immune regulatory effects on T cells in this study.

To verify the successful fabrication of TFNA, the morphology of TFNA was observed by atomic force microscopy (AFM) and dynamic light scattering. The regulatory effect of TFNA was evaluated by flow cytometry after cocultured with CD3+ T cells isolated from healthy donors. Moreover, the associated signaling pathways were investigated. Finally, we verified our results on the T cells from patients with neuromyelitis optica spectrum disorder (NMOSD), which is a typical autoimmune disease induced by T cells.

We revealed the alternative regulatory functions of TFNA in human primary T cells with steady status via the JNK signaling pathway. Moreover, by inhibiting both JNK and ERK phosphorylation, TFNA exhibited significant suppressive effects on IFNγ secretion from provoking T cells without affecting TNF secretion. Similar immune regulatory effects of TFNA were also observed in autoreactive T cells from patients with NMOSD.

Overall, our results revealed a potential application of TFNA in regulating the adaptive immune system, as well as shed a light on the treatment of T cell-mediated autoimmune diseases.

Stress granules (SGs) are condensed membrane-less organelles dynamically formed in the cytoplasm of eukaryotes cells to cope with diverse intracellular or extracellular stress factors, with features of liquid-liquid phase separation. They are composed of multiple constituents, including translationally stalled mRNAs, translation initiation factors, RNA-binding proteins and also non-RNA-binding proteins. SG formation is triggered by stress stimuli, viral infection and signal transduction, while aberrant assembly of SGs may contribute to tissue degenerative diseases. Recently, a growing body of evidence has emerged on SG response mechanisms for cells facing high temperatures, oxidative stress and osmotic stress. In this review, we aim to summarize factors affecting SGs assembly, present the impact of SGs on germ cell development and other biological processes. We particularly emphasize the significance of recently reported RNA modifications in SG stress responses. In parallel, we also review all current perspectives on the roles of SGs in male germ cells, with a particular focus on the dynamics of SG assembly.
A growing body of literature suggests alcohol industry corporate social responsibility activity, including the creation of 'social aspects' organisations (SAO), may harm rather than improve public health. We aimed to explore established researcher experiences of working with SAOs, and the factors informing their decisions to do so.

Qualitative interview study with senior alcohol researchers who had previous or ongoing connections to SAOs or their predecessors initiated when their careers were established (n= 16). Thematic analysis using NVivo software.

Established researchers were recruited for their expertise by alcohol industry SAOs via employees who were previously academics or via academic colleagues with SAO connections. Motivated by the desire to improve public health and 'reach out' beyond academia, researchers were confident that they could maintain their independence when sharing their expertise with SAOs. Short-term connections included attendance at SAO-funded events and book chapter contributions.
