'Monitoring of immune responses following mogamulizumab-containing treatment in patients with adult T-cell leukaemia-lymphoma (ATL)' (MIMOGA) is a multicentre prospective clinical study (UMIN000008696). In the MIMOGA study, we found that a lower percentage of CD2- CD19+ B cells in peripheral blood mononuclear cells (PBMC) was a significant unfavourable prognostic factor for overall survival (OS). Accordingly, we then analysed the immunoglobulin G (IgG) heavy-chain repertoire in PBMC by high-throughput sequencing. Of the 101 patients enrolled in the MIMOGA study, for 81 a sufficient amount of PBMC RNA was available for repertoire sequencing analysis. Peripheral IgG B cells in patients with ATL had a restricted repertoire relative to those in healthy individuals. There was a significant positive correlation between the Shannon-Weaver diversity index (SWDI) for the IgG repertoire and proportions of B cells in the PBMC of the patients. Multivariate analysis identified two variables significantly affecting OS a higher serum soluble interleukin-2 receptor level, and a lower SWDI for the IgG repertoire [hazard ratio, 2·124; 95% confidence interval, 1·114-4·049; n = 44]. The present study documents the importance of humoral immune responses in patients receiving mogamulizumab-containing treatment. Further investigation of strategies to enhance humoral immune responses in patients with ATL is warranted.Pyroptosis is a specialized form of inflammatory cell death which aids the defensive response against invading pathogens. Its normally tight regulation is lost during infection by the severe acute respiratory coronavirus 2 (SARS-CoV-2), and thus, uncontrolled pyroptosis disrupts the immune system and the integrity of organs defining the critical conditions in patients with high viral load. Molecular pathways engaged downstream of the formation and stabilization of the inflammasome, which are necessary to execute the process, have been uncovered and drugs are available for their regulation. However, the pharmacology of the upstream events, which are critical to sense and interpret the initial damage by the pathogen, is far from being elucidated. This limits our capacity to identify early markers and targets to ameliorate SARS-CoV-2 linked pyroptosis. Here, we focus attention on the mitochondria and pathways leading to their dysfunction, in order to elucidate the early steps of inflammasome formation and devise tools to predict and counter pathological states induced by SARS-CoV-2.Random effects in longitudinal multilevel models represent individuals' deviations from population means and are indicators of individual differences. Researchers are often interested in examining how these random effects predict outcome variables that vary across individuals. This can be done via a two-step approach in which empirical Bayes (EB) estimates of the random effects are extracted and then treated as observed predictor variables in follow-up regression analyses. This approach ignores the unreliability of EB estimates, leading to underestimation of regression coefficients. As such, previous studies have recommended a multilevel structural equation modeling (ML-SEM) approach that treats random effects as latent variables. The current study uses simulation and empirical data to show that a bias-variance tradeoff exists when selecting between the two approaches. ML-SEM produces generally unbiased regression coefficient estimates but also larger standard errors, which can lead to lower power than the two-step approach. Implications of the results for model selection and alternative solutions are discussed.
In plants, populations and species vary widely along the continuum from outcrossing to selfing. Life-history traits and ecological circumstances influence among-species variation in selfing rates but their general role in explaining intraspecific variation is unknown. Using a database of plant species, we test whether life-history traits, geographic range position, or abundance predict selfing rate variation among populations.
We identified species where selfing rates were estimated in at least three populations at known locations. Two key life-history traits (generation time and growth form) were used to predict within-species selfing rate variation. Populations sampled within a species' native range were assessed for proximity to the nearest edge and abundance. Finally, we conducted linear and segmented regressions to determine functional relationships between selfing rate and geographic range position within species.
While woody species exhibit lower variation in selfing rates compared to herbs, thisphylogeographic information concerning specific range edges, the study of traits influencing mating system (e.g. herkogamy), and measures of abundance at local scales (e.g. population density).

The aim of this study was to develop a bilayered in vitro construct that simulated the tooth periodontal ligament and attached alveolar bone, for the purpose of tissue regeneration and investigation of physiological and orthodontic loading. Two types of materials were used to develop this construct sol-gel 60S10Mg derived scaffold, representing the hard tissue component of the periodontium, and commercially available Geistlich Bio-Gide® collagen membrane, representing the soft tissue component of the tooth attachment. Each scaffold was dynamically seeded with human periodontal ligament cells (HPDLCs). Scaffolds were either cultured separately, or combined in a bilayered construct, for 2 weeks. Characterisation of the individual scaffolds and the bilayered constructs included biological characterisation (cell viability, scanning electron microscopy to confirm cell attachment, gene expression of periodontium regeneration markers), and mechanical characterisation of scaffolds and constructs. HPDLCs enjoyed a biocompatible 3-dimensional environment within the bilayered construct components. There was no drop in cellular gene expression in the bilayered construct, compared to the separate scaffolds.Meganucleases are rare cutting enzymes that can generate DNA modifications and are part of the plant genome editing toolkit although they lack versatility. Here, we evaluated the use of two meganucleases, I-SceI and a customized meganuclease, in tomato and oilseed rape. Different strategies were explored for the use of these meganucleases. The activity of a customized and a I-SceI meganucleases was first estimated by the use of a reporter construct GFFP with the target sequences and enabled to demonstrate that both meganucleases can generate double-strand break and HDR mediated recombination in a reporter gene. Interestingly, I-SceI seems to have a higher DSB efficiency than the customized meganuclease up to 62.5% in tomato and 44.8% in oilseed rape. Secondly, the same exogenous landing pad was introduced in both species. Despite being less efficient compared to I-SceI, the customized meganuclease was able to generate the excision of an exogenous transgene (large deletion of up to 3316 bp) present in tomato. In this paper, we also present some pitfalls to be considered before using meganucleases (e.g., potential toxicity) for plant genome editing.
RalA is a member of the Ras superfamily of small GTPases. The Anti-RalA autoantibodies (s-RalA-Abs) act as tumor markers in various types of cancer and are negatively associated with the p53 autoantibodies (s-p53-Abs). This study aimed to evaluate the relationship between s-RalA-Abs and s-p53-Abs in various types of cancer.
A total of 1833 cancer patients (esophageal cancer, 172; hepatocellular carcinoma, 91; lung cancer, 269; gastric cancer, 317; colon cancer, 262; breast cancer, 364; and prostate cancer, 358) and 73 healthy subjects were enrolled in the study. The levels of s-RalA-Abs and s-p53-Abs were analyzed using enzyme-linked immunosorbent assay, and the positivity rates and relations between the two autoantibodies were evaluated. The cutoff values for s-RalA abs and s-p53 abs were set as mean + 2 standard deviation and the values higher than the cutoff values were defined as positive.
The titers in all cancer types were significantly higher than those in the controls (P < 0.01). The positivity rates for s-RalA-Abs ranged between 11.7 and 21.5%, and those for s-p53-Abs ranged between 12 and 28.5%. A combined assay of the two antibodies revealed positivity rates of 20.9 and 44.2%. In Stage 0/I/II tumors, the positivity rates of the combination of the two antibodies ranged between 21.5 and 42.3%. The two autoantibodies were complementary to each other in the prostate and breast cancers, but independent in other carcinomas.
The combined use of s-RalA-Abs and s-p53-Abs tended to increase the positivity rate in all cancers, including Stage 0/I/II cancers.

Mediastinal and abdominal lymphatic malformations may not be diagnosed until adulthood. Radiologic and pathologic diagnosis is often challenging due to the rarity of the lesion. Surgical excision of these lesions may be curative but lymphatic leak is a known complication. Lymphatic duct embolization may then be required to treat the leak.
We describe a patient with post-surgical chylothorax where thoracic duct lymphangiography and embolization was performed by catheterizing the thoracic duct at the venous angle where it drains into the subclavian vein.
Lymphatic duct embolization can be challenging in patients with lymphatic malformations. In these patients, if there is adequate visualization on ultrasound or fluoroscopy, terminal aspect of the thoracic duct can be accessed through the subclavian vein to perform the procedure.

Our objective was to describe the efficacy and safety of furosemide and chlorothiazide combination continuous infusion (FCCCI) in children in a pediatric intensive care unit (ICU), including postoperative cardiac patients.
This was a retrospective cohort study in a pediatric ICU within a tertiary care teaching hospital. Children aged < 18 years admitted from 1 January 2010 to 31 December 2019 were included if they received a furosemide infusion for at least 6 h and then transitioned to FCCCI. Each patient acted as their own control.
A total of 203 patients (107 [53%] postoperative cardiac) met the study inclusion criteria. The study population was 55% male and 74% Caucasian, with a median age of 4.9 months. Of the total patients, 143 (70.4%) required mechanical ventilation and 39 (19.2%) required dialysis. The median duration of furosemide and FCCCI was 24.6 h (interquartile range [IQR] 12.4-54) and 41 h (IQR 15-162), respectively. Urine output increased by 52% with FCCCI (mean increase of 2.2 mL/kg/h [95% confidence interval CI 1.
