    Abstract Previously, we generated thymic lymphoma cell lines from EbetaR/Rp53-/- (EP) double mutant mice where the T cell receptor (TCR) beta enhancer (Ebeta) was deleted, and the p53 gene was inactivated. Here, we characterized the EP cell lines to study the roles of the Ebeta and p53 on TCRbeta rearrangements during lymphomagenesis. Recombination activation genes (RAGs) were expressed, while the TCRbeta chain was not expressed in the EP cell lines. Dbeta-Jbeta rearrangements were not detected at all, and Dbeta1 and Dbeta2 cleavages were also not detected in the EP cell lines. However, Jbeta cleavages suppressed in Ebeta mutant thymocytes were readily detected in the EP cell lines. The Jbeta cleavages appeared to be uncoupled, aberrant, RAG-dependent and Ebeta-independent and were not detected in a p53 or Ebeta single mutant background, suggesting that the Jbeta cleavages are selected in the Ebeta and p53 double mutant background. Sequence analysis showed that the cleavage occurred in the cryptic recombination signal sequences (RSSs) present throughout Jbeta gene segments. The results implicate that the uncoupled and aberrant V(D)J cleavages may contribute to double-strand break-mediated genome instability during lymphomagenesis in EP mice.

    Abstract The precise function of cis elements in regulating V(D)J recombination is still controversial. Here, we determined the effect of inactivation of the TCRbeta enhancer (Ebeta) on cleavage and rearrangement of Dbeta1, Dbeta2, Jbeta1, and Jbeta2 gene segments in CD4-CD8- [double-negative (DN)] and CD4+CD8+ [double-positive (DP)] thymocytes. In Ebeta-deficient mice, (i) Dbeta1 rearrangements were more severely impaired than Dbeta2 rearrangements; (ii) most of the Dbeta and Jbeta cleavages and rearrangements occurred in DP, rather than in DN, thymocytes; and (iii) most of the 3' Dbeta1 cleavages were coupled to 5' Dbeta2 cleavages instead of to Jbeta cleavages, resulting in nonstandard Dbeta1-Dbeta2-Jbeta2 joints. These findings suggest that the Ebeta regulates TCRbeta rearrangement by promoting accessibility of Dbeta and Jbeta gene segments in DN thymocytes and proper pairing between Dbeta1 and Jbeta gene segments for cleavage and joining in DP thymocytes.

    Abstract Objective: To obtain insight into the molecular mechanism of acute leukemia in elderly patients in relation to the clinical features of the disease.
    Methods: DNA specimens were obtained from 34 elderly patients with acute nonlymphoblastic leukemia (ANLL), 9 elderly patients with acute lymphoblastic leukemia (ALL) and 10 healthy blood donors. Polymerase chain reaction (PCR) coupled with single-strand conformation polymorphism (SSCP) was performed to detect T cell receptor (TCR) V gamma I-J gamma gene rearrangement.
    Results: In the 34 elderly ANLL patients, 47.1% (16/34) were found with TCRV gamma I-J gamma gene rearrangement, showing a higher rate of the rearrangement than in younger ANLL patients (P<0.025). TCRV gamma I-J gamma gene rearrangement was identified in 7 (77.8%) of the 9 elderly patients with ALL, and 3 of the identified cases had oligoclonal/ subclonal rearrangement, suggesting a higher rate of oligoclonal/subclonal rearrangement in elderly ALL patients than in younger ALL patients (P<0.01). None of the blood donors was found with TCRV gamma I-J gamma gene rearrangement. The complete remission rate was lower in the elderly ANLL patient with TCRV gamma I-J gamma gene rearrangement than in those without (P<0.05).
    Conclusion: The detection of TCRV gamma I-J gamma gene rearrangement can be of value in assessing the therapeutic effect and making prognostic prediction in elderly patients with acute leukemia.

    Abstract The content of kernel starch (STC), which is a fundamental indicator of the nutritional value of maize, is directly correlated with the grain's taste and aroma. Both calcium (Ca) and magnesium (Mg) are critical nutrients that play a significant role in the growth and development of maize, as well as in the synthesis of STC. To determine the physiological driving mechanisms of Ca and Mg effects on the accumulation of STC synthesis in maize kernels and the characteristics of their effects on endogenous hormones and enzymes of STC synthesis in maize leaves, our study applied foliar Ca and Mg fertilizers at various levels to maize prior to pollination. (1) The levels of Ca, Mg, indole-3-acetic acid (IAA), gibberellin (GA), and zeatin riboside (ZR) in maize leaves increased and then decreased after the supplementation of Ca and Mg. They peaked on the 32nd day after pollination. In contrast, the levels of abscisic acid (ABA) initially decreased and then increased. Ca and Mg had a negative correlation with ABA and a positive correlation with IAA, GA, and ZR. (2) As the levels of Ca and Mg increased, correspondingly rose the activities of enzymes responsible for STC synthesis and the content of STC and its components. Principally influencing the synthesis of STC were ABA, IAA, uridine diphosphate-glucose pyrophosphorylase (UDPG), granule-bound starch synthase (GBSS), and soluble starch synthase (SSS). (3) "IAA-UDPG or GBSS-STC" was the predominant physiological regulation pathway of Ca on kernel STC, whereas "IAA-GBSS-STC" was the dominant physiological regulation pathway of Mg on kernel STC. The regulatory impact of STC by UDPG and GBSS was positive, as were the effects of IAA on UDPG and GBSS. In conclusion, the accumulation of kernel starch was significantly enhanced by Ca and Mg supplementation via the modulation of endogenous hormone levels and key enzyme activities. This research identifies a viable approach to improve the nutritional composition of maize.

    Abstract Despite advances in high-dimensional cellular analysis, the molecular profiling of dynamic behaviors of cells in their native environment remains a major challenge. We present a method that allows us to couple the physiological behaviors of cells in an intact murine tissue to deep molecular profiling of individual cells. This method enabled us to establish a novel molecular signature for a striking migratory cellular behavior following injury in murine airways.

    Abstract Exercise plays an important role in regulating energy homeostasis, which affects the diversity of the intestinal microbial community in humans and animals. To the best of the authors' knowledge, few studies have reported the associations between horse gut microbiota along with their predicted metabolic activities and the athletic ability of Jeju horses and Thoroughbreds living in Korea. This study was conducted to investigate the association between the gut microbiota and athletic performance in horses. This study sequenced the V3 and V4 hypervariable regions of the partial 16S rRNA genes obtained from racehorse fecal samples and compared the fecal microbiota between high- and low-performance Jeju horses and Thoroughbreds. Forty-nine fecal samples were divided into four groups: high-performance Jeju horses (HJ, n = 13), low-performance Jeju horses (LJ, n = 17), high-performance Thoroughbreds (HT, n = 9), and low-performance Thoroughbreds (LT, n = 10). The high-performance horse groups had a higher diversity of the bacterial community than the low-performance horse groups. Two common functional metabolic activities of the hindgut microbiota (i.e., tryptophan and succinate syntheses) were observed between the low-performance horse groups, indicating dysbiosis of gut microbiota and fatigue from exercise. On the other hand, high-performance horse groups showed enriched production of polyamines, butyrate, and vitamin K. The racing performance may be associated with the composition of the intestinal microbiota of Jeju horses and Thoroughbreds in Korea.

    Abstract Study objective: HRAD± was developed to quickly assess pediatric perioperative affect and cooperation. HRAD± represents: Happy, Relaxed, Anxious, Distressed, with a yes/no answer to cooperativity. The primary aim of this study was to investigate the clinical utility of HRAD± as an affect and cooperation assessment tool for inhalational mask induction. Secondary aims examined inter-rater reliability (IRR) of HRAD± and predictive validity of induction HRAD± with emergence delirium.
    Design: This was a prospective observational investigation.
    Setting: We conducted this investigation at Lucile Packard Children's Hospital Stanford, an academic, quaternary care children's hospital in Northern California.
    Patients: A total of 197 patients were included in this investigation. Children 1-14 years of age, who underwent daytime procedures with inhalational induction of anesthesia and American Society of Anesthesiologists physical status I-III were eligible.
    Interventions: During mask induction, two trained research assistants (RAs) independently scored the patient's affect and cooperation. After extubation, the same investigators observed the patient's emergence.
    Measurements: RAs scored each mask induction using the following scales: HRAD±, modified Yale Preoperative Anxiety Scale (mYPAS), Observation Scale of Behavioral Distress (OSBD), and Induction Compliance Checklist (ICC). Correlations were calculated to HRAD±. IRR of HRAD± between the RAs as well as predictive validity of HRAD± to Pediatric Anesthesia Emergence Delirium (PAED), Watcha and Cravero scales were calculated.
    Main results: HRAD± scores strongly correlated with mYPAS (r = 0.840, p < 0.0001) with moderate correlation to OSBD (r = 0.685, p < 0.0001) and ICC (-0.663, p < 0.0001). IRR was moderate for the affect and cooperation portion of the HRAD± scale, respectively (κ = 0.595 [p < 0.0001], κ = 0.478 [p < 0.0001]). A weak correlation was observed with PAED (r = 0.134 [p = 0.0597]) vs HRAD±. No correlations were observed between Watcha (r = 0.013 [p = 0.8559]) and Cravero and HRAD± scales (r = 0.002 [p = 0.9767]).
    Conclusions: HRAD± is a clinically useful and simple scale for evaluating pediatric affect and cooperation during inhalational mask induction. Results demonstrate correlation with commonly utilized research assessment scales.

    Abstract Allergic rhinitis (AR) is a type I hypersensitivity mediated by dominant T helper 2 (Th2) response over the Th1 response after re-exposure to a specific allergen. Currently, socio-economic cost evoked by AR is quickly increasing since the prevalence of AR is gradually increasing in all ages worldwide. Several probiotic Lactobacillus strains have been described with potential immunomodulatory effects against type I hypersensitivity such as AR. Thus, the aim of the present work was to characterize basic probiotic property and immunomodulatory role of newly isolated Lactobacillus strains from Kimchi, a traditional fermented Korean food, in AR. Among the identified strains, Lactiplantibacillus plantarum NR16 revealed to be a powerful Th1 inducer since immune cells co-cultured with NR16 produced the highest quantity of interferon-γ (IFN-γ) and interleukin-12 (IL-12) but secreted a low amount of IL-4 in vitro. Therefore, NR16 was selected for the following assays conducted with mice with birch pollen-induced AR. Oral administration of NR16 reduced airway hyperresponsiveness and leukocyte infiltration in lesions of mice. In conclusion, oral administration of NR16 may mitigate symptoms of AR by inducing Th1 immune response, which might rebalance Th2/Th1 ratio by decreasing Th2 cytokine production in specific lesions of mucosa.
