BACKGROUND: Ki-67 immunostaining is commonly used in neuroendocrine tumors to estimate the proliferative index and for grading. This study investigates its association with the invasiveness of follicular-derived thyroid carcinomas (TCs).
METHODS: A retrospective analysis of patients with TC at three McGill University teaching hospitals between January 2018 and November 2023 was conducted. The inclusion criteria included patients with malignant thyroid tumors and accessible Ki-67 LI data from final pathology specimens. The data collected included patient demographics, Ki-67 LI values, and different invasiveness attributes, such as molecular mutations, the histological subtype, lymphovascular invasion (LVI), extrathyroidal extension (ETE), and positive lymph nodes (LNs).
RESULTS: In total, 212 patients met the inclusion criteria, of which 80.7% were females and 19.3% were males. The Ki-67 LI ranged from 1% to 30%, with the majority of the cases within the range of 1-15%. A significant association was observed between higher Ki-67 LI and high-risk histological subtypes of thyroid carcinoma (p < 0.001). Similarly, Ki-67 LI was significantly associated with LVI and positive LN metastasis (p < 0.001 and p = 0.036, respectively). However, no significant association was found between the Ki-67 LI and gene mutations or ETE (p = 0.133 and p = 0.190, respectively). Using percentiles to establish a cutoff, patients with a Ki-67 LI higher than 6.7 showed a higher likelihood of being associated with invasive features.
CONCLUSION: Elevated Ki-67 LI can serve as an indicator of aggressiveness in follicular-derived TC, especially when associated with distinct histological subtypes, LVI and positive LNs.

Lignin is a complex polymer found in the cell walls of plants, providing structural support and protection against pathogens. By modifying lignin composition and structure, scientists aim to optimize plant defense responses and increase resistance to pathogens. This can be achieved through various genetic engineering techniques which involve manipulating the genes responsible for lignin synthesis. By either up regulating or down regulating specific genes, researchers can alter the lignin content, composition, or distribution in plant tissues. Reducing lignin content in specific tissues like leaves can improve the effectiveness of defense mechanisms by allowing for better penetration of antimicrobial compounds. Overall, Lignin modification through techniques has shown promising results in enhancing various plants resistance against pathogens. Furthermore, lignin modification can have additional benefits beyond pathogen resistance. It can improve biomass processing for biofuel production by reducing lignin recalcitrance, making the extraction of sugars from cellulose more efficient. The complexity of lignin biosynthesis and its interactions with other plant components make it a challenging target for modification. Additionally, the potential environmental impact and regulatory considerations associated with genetically modified organisms (GMOs) require careful evaluation. Ongoing research aims to further optimize this approach and develop sustainable solutions for crop protection.

The biological role and precise molecular mechanisms of Notch receptor 3 (NOTCH3) in the malignant progression of bladder cancer (BLCA) remain unclear. In this study, we found that NOTCH3 was significantly upregulated and associated with poor prognosis in BLCA patients. Functional experiments demonstrated that NOTCH3 knockdown inhibited BLCA cell proliferation, migration, invasion and significantly suppressed tumor growth and metastasis in vivo as well. Mechanically, chromatin immunoprecipitation and dual-luciferase reporter assays confirmed that NOTCH3 could promote the transcription of secreted phosphoprotein 1 (SPP1), a potential downstream target gene of NOTCH3, by binding to the CSL elements in the SPP1 promoter. Moreover, we also found that targeting NOTCH3 inhibited BLCA growth and metastasis by suppressing the SPP1-PI3K/AKT axis. Our study highlights the critical role of NOTCH3-SPP1-PI3K/AKT axis in the malignant progression of BLCA, suggesting that NOTCH3 may be a potential therapeutic target for BLCA.
BACKGROUND: Bile chemistry during normothermic ex situ liver perfusion (NESLiP) has been suggested to be an indicator of cholangiopathy. The normal range of biochemical variables in bile of livers undergoing NESLiP has not been defined, nor have published biliary viability criteria been assessed against instances of posttransplant nonanastomotic bile strictures (NASs).
METHODS: The bile and perfusate chemistry of 200 livers undergoing NESLiP between February 1, 2018, and October 30, 2023, was compared. In addition, 11 livers that underwent NESLiP and later developed NAS were selected and their bile chemistry was also examined.
RESULTS: In livers that did not develop cholangiopathy, concentrations of sodium, potassium, and chloride were slightly higher in bile than in perfusate, whereas the concentration of calcium was slightly lower. Bile was alkali and had a lower glucose concentration than perfusate. Cholangiocyte glucose reabsorption was shown to saturate at high perfusate concentrations and was more impaired in livers donated after circulatory death than in livers donated after brain death. Published criteria failed to identify all livers that went on to develop NASs.
CONCLUSIONS: A significant false-negative rate exists with current biliary viability criteria, probably reflecting the patchy and incomplete nature of the development of NASs in the biliary tree. The data presented here provide a benchmark for future assessment of bile duct chemistry during NESLiP.

A glucose biosensor includes a plurality of optical fibers configured for placement within the ear canal. A first optical fiber emits light into the ear canal. A plurality of other optical fibers capture and transmit the reflected light back to the glucose biosensor. A plurality of photodetectors are configured in the glucose biosensor to detect the reflected light from the plurality of optical fibers. The glucose biosensor processes the detected light from each photodetector to determine a glucose level measurement. In an embodiment, the glucose biosensor also obtains a second glucose level measurement using another method and determines a calibration for the first glucose level measurement using the second glucose level measurement.
Efavirenz, an antiretroviral drug used for the treatment of human immunodeficiency virus 1 (HIV-1) infections, is known for its neurological and psychiatric adverse events. Efavirenz is part of Atripla®, a single tablet regimen (STR), currently the most prescribed antiretroviral drug in the Netherlands. Recently, a new STR has become available, Eviplera® containing a successor of Efavirenz, named Rilpivirin. It has been shown in the phase-3 ECHO and THRIVE studies that Atripla as well as Eviplera have excellent and comparable antiretroviral efficacy in naive HIV-infected patients. Furthermore, data from these studies have shown that Eviplera was associated with fewer neurological and psychiatric adverse events than Atripla over 48 weeks. However, this was only patient reported adverse events, not neuropsychological evaluation. Furthermore, they were treatment naïve for HIV. Moreover, there might be a bias in these kind of switch studies due to the fact that those patients who switch will mostly regard their new combination better than the old one. Contrary, data on the long term impact of Efavirenz on neuropsychological performance and symptoms are conflicting.

Objective: This study aims to investigate the effect of switching from Atripla to Eviplera on neurocognitive performances (neurocognitive testing) and imaging (functional MRI scanning) in virologically suppressed HIV-infected patients.
Sphingosine-1-phosphate (S1P) receptor (S1PR) agonists, such as fingolimod (FTY720), alleviate nociception in preclinical pain models by either activation (agonism) or inhibition (functional antagonism) of S1PR type-1 (S1PR1). However, the dose-dependence and temporal relationship between reversal of nociception and modulation of S1PR1 signaling has not been systematically investigated. This study examined the relationship between FTY720-induced antinociception and S1PR1 adaptation using a sciatic nerve chronic constriction injury (CCI) model of neuropathic pain in male and female C57Bl/6J mice. Daily injections of FTY720 for 14 days dose-dependently reversed CCI-induced mechanical allodynia without tolerance development, and concomitantly resulted in a dose-dependent reduction of G-protein activation by the S1PR1-selective agonist SEW2871 in the lumbar spinal cord and brain. These findings indicate FTY720-induced desensitization of S1PR1 signaling coincides with its anti-allodynic effects. Consistent with this finding, a single injection of FTY720 reversed mechanical allodynia while concomitantly producing partial desensitization of S1PR1-stimulated G-protein activation in the CNS. However, mechanical allodynia returned 24-hr post injection, despite S1PR1 desensitization at that time, demonstrating a dissociation between these measures. Furthermore, CCI surgery led to elevations of sphingolipid metabolites, including S1P, which were unaffected by daily FTY720 administration, suggesting FTY720 reversed mechanical allodynia by targeting S1PR1 rather than sphingolipid metabolism. Supporting this hypothesis, acute administration of the S1PR1-selective agonist CYM-5442 mimicked the anti-allodynic effect of FTY720. In contrast, the S1PR1-selective antagonist NIBR-0213 prevented the anti-allodynic effect of FTY720, but NIBR-0213 given alone did not affect nociception. These results indicate that FTY720 alleviates CCI-induced allodynia through a mechanism distinct from functional antagonism.
Choline is an essential nutrient that can be found in foods, such as egg yolks, liver, and other meats. It is important for the composition and repair of normal cellular membranes, normal brain function, and normal cardiovascular function. Research has suggested that the presence of adequate amounts of choline during pregnancy and breastfeeding can help ensure healthy fetal brain development. Additionally, adequate prenatal choline levels may have long-lasting positive effects on cognitive function, including memory. However, sufficient research has not been done on the effects of choline on pregnant women and their unborn babies. This study will evaluate the safety and effectiveness of taking choline supplements during pregnancy, and whether taking choline during pregnancy will have an effect on infant development.

Participants in this double-blind study will be randomly assigned to receive either placebo or 1250 mg of choline daily throughout pregnancy, until delivery. Vital signs will be taken, potential side effects will be assessed, and study medication will be given at each visit. Blood samples will be taken at enrollment and approximately at weeks 20, 28, 32. Children will be followed and assessed until 4 years of age.
Frequent itching and incessant scratching are commonly observed in various chronic inflammatory skin conditions, including atopic dermatitis and psoriasis. The persistent and prolonged nature of pruritus can worsen one's quality of life. Keratinocytes (KCs), the predominant cells of the epidermis, have been confirmed to interact with sensory neurons and immune cells and be involved in chronic skin inflammatory diseases associated with pruritus. Initially, KCs and sensory neurons form a unique synapse-like connection within the epidermis, serving as the structural foundation for their interaction. Additionally, several receptors, including toll-like receptors and protease-activated receptor 2, expressed on KCs, become activated in an inflammatory milieu. On the one hand, activated KCs are sources of pro-inflammatory cytokines and neurotrophic factors, such as adenosine triphosphate, thymic stromal lymphopoietin, and nerve growth factor, which directly or indirectly participate in stimulating sensory neurons, thereby contributing to the itch sensations. On the other hand, KCs also function as primary transducers alongside intraepidermal nerve endings, directly initiating pruritic responses. This review summarizes the current literature and highlights the critical role of KCs in the development and persistence of chronic itch in inflammatory skin disorders.

Intramural NIAID sponsored several phase I-II studies of cell transfers during the 1990's, including gene-modified cells, in identical twins discordant for HIV infection. These studies were both novel in the field of alternative treatment strategies for HIV infection and served as early studies in the developing field of clinical gene therapy. The current protocol represents an umbrella protocol in which these early trials have been consolidated for purposes of long-term safety monitoring and long-term follow-up of gene-modified cell persistence. Cell recipients as well as donors enrolled in Intramural NIAID twin gene marking, gene therapy and cell transfer studies have been eligible for study participation. Participants are monitored for safety per a uniform standardized schedule. No gene therapy, cell transfers or other investigational therapeutic interventions occur under the auspices of this protocol.
BACKGROUND: The role of Mediator complex subunit 1 (MED1), a pivotal transcriptional coactivator implicated in diverse biological pathways, remains unexplored in the context of oral squamous cell carcinoma (OSCC). This study aims to elucidate the contributory mechanisms and potential impact of MED1 on the progression of OSCC.
METHODS: The expression and clinical significance of MED1 in OSCC tissues were evaluated through the bioinformatics analyses. The effects of MED1 on the biological behavior of OSCC cancer cells were assessed both in vitro and in vivo. Dual-luciferase reporter assay, chromatin immunoprecipitation (ChIP) assay, bioinformatic analysis, CD8+ T cell isolation experiment, coculture experiment, enzyme-linked immunosorbent assay (ELISA), and flow cytometric analysis were employed to elucidate the underlying mechanism through which MED1 operates in the progression of OSCC.
RESULTS: MED1 exhibited upregulation in both OSCC tissues and multiple OSCC cell lines, which correlated with decreased overall survival in patients. In vitro experiments demonstrated that knockdown of MED1 in metastatic OSCC cell lines SCC-9 and UPCI-SCC-154 hindered cell migration and invasion, while overexpression of MED1 promoted these processes. Whereas, MED1 knockdown had no impact on proliferation of cell lines mentioned above. In vivo studies further revealed that downregulation of MED1 effectively suppressed distant metastasis in OSCC. Mechanistically, MED1 enhanced the binding of transcription factors c-Jun and c-Fos to the matrix metalloprotein 9 (MMP9) promoters, resulting in a significant upregulation of MMP9 transcription. This process contributes to the migration and invasion of SCC-9 and UPCI-SCC-154 cells. Furthermore, MED1 modulated the expression of programmed death-ligand 1 (PD-L1) through the Notch signaling pathway, consequently impacting the tumor-killing capacity of CD8+ T cells in the tumor microenvironment.
CONCLUSIONS: Our findings indicate that MED1 plays a pivotal role in OSCC progression through the activation of MMP9 transcription and suppression of CD8+ T cell antitumor immunity, suggesting that MED1 may serve as a novel prognostic marker and therapeutic target in OSCC.

Provided is a method for controlling the propagation and differentiation of hematopoietic stem cells derived from umbilical cord blood. The method displays superior safety for propagation by culturing of the hematopoietic stem cells. The hematopoietic stem cells are seeded in a medium containing the ultrasound-treated liquid component of umbilical cord blood. Propagation and differentiation of umbilical cord blood hematopoietic stem cells can be suppressed as long as operations are performed in the presence of the ultrasound-treated liquid component of umbilical cord blood. On the other hand, propagation of umbilical cord blood hematopoietic stem cells can be promoted by seeding the hematopoietic stem cells in a medium containing the liquid component of umbilical cord blood that has not been subjected to ultrasound treatment. Thus, it is possible to arbitrarily control propagation and differentiation and promote propagation of umbilical cord blood hematopoietic stem cells by using serum derived from umbilical cord blood.
