Abstract

On behalf of Cell Therapy Transplant Canada (CTTC), we are pleased to present the Abstracts of the CTTC 2023 Annual Conference. The conference was held in-person, 31 May–2 June 2023, in Halifax, Nova Scotia at the Westin Nova Scotian hotel. Poster authors presented their work during a lively and engaging welcome reception on Thursday, 1 June, and oral abstract authors were featured during the oral abstract session in the afternoon of Friday, 2 June 2023. Twenty-three (23) abstracts were selected for presentation as posters and four (4) as oral presentations. Abstracts were submitted within four categories: (1) Basic/Translational Sciences, (2) Clinical Trials/Observations, (3) Laboratory/Quality, and (4) Pharmacy/Nursing/Other Transplant Support. The top four (4) oral abstracts and top four (4) poster abstracts were selected to receive an award. All of these were marked as “Award Recipient” within the relevant category. We congratulate all the presenters on their research and contributions to the field.

Abstract

ABSTRACTThe diet during pregnancy, or antenatal diet, influences the offspring’s intestinal health. We previously showed that antenatal butyrate supplementation reduces injury in adult murine offspring with dextran sulfate sodium (DSS)-induced colitis. Potential modulators of butyrate levels in the intestine include a high fiber diet or dietary supplementation with probiotics. To test this, we supplemented the diet of pregnant mice with high fiber, or with the probiotic bacteria Lactococcus lactis subspecies cremoris or Lactobacillus rhamnosus GG. We then induced chronic colitis with DSS in their adult offspring. We demonstrate that a high fiber antenatal diet, or supplementation with Lactococcus lactis subspecies cremoris during pregnancy diminished the injury from DSS-induced colitis in offspring. These data are evidence that antenatal dietary interventions impact offspring gut health and define the antenatal diet as a therapeutic modality to enhance offspring intestinal health.

Abstract

Abstract Antibodies to programmed cell death protein 1 (anti‐PD‐1) have become a promising immunotherapy for triple negative breast cancer (TNBC), blocking PD‐L1 signaling from pro‐tumor cells through T cell PD‐1 receptor binding. Nevertheless, only 10%–20% of PD‐L1+ metastatic TNBC patients who meet criteria benefit from immune checkpoint blockade (ICB), and biomarkers to predict patient response have been elusive. We have previously developed an immunological niche, consisting of a microporous implant in the subcutaneous space, that supports tissue formation whose immune composition is consistent with that within vital organs. Herein, we investigated dynamic gene expression within this immunological niche to provide biomarkers of response to anti‐PD‐1. In a 4T1 model of metastatic TNBC, we observed sensitivity and resistance to anti‐PD‐1 based on primary tumor growth and survival. The niche was biopsied before, during, and after anti‐PD‐1 therapy, and analyzed for cell types and gene expression indicative of treatment refractivity. Myeloid cell‐to‐lymphocyte ratios were altered between ICB‐sensitivity and resistance. Longitudinal analysis of gene expression implicated dynamic myeloid cell function that stratified sensitivity from resistance. A niche‐derived gene signature predicted sensitivity or resistance prior to therapy. Analysis of the niche to monitor immunotherapy response presents a new opportunity to personalize care and investigate mechanisms underlying treatment resistance. Summary: A remote implant identified biomarkers that predict anti‐PD‐1 response before therapy, providing a unique tool to understand heterologous immunotherapy resistance in triple negative breast cancer.

Abstract

Abstract Biomaterial scaffolds mimicking the environment in metastatic organs can deconstruct complex signals and facilitate the study of cancer progression and metastasis. Here we report that a subcutaneous scaffold implant in mouse models of metastatic breast cancer in female mice recruits lung-tropic circulating tumor cells yet suppresses their growth through potent in situ antitumor immunity. In contrast, the lung, the endogenous metastatic organ for these models, develops lethal metastases in aggressive breast cancer, with less aggressive tumor models developing dormant lungs suppressing tumor growth. Our study reveals multifaceted roles of neutrophils in regulating metastasis. Breast cancer-educated neutrophils infiltrate the scaffold implants and lungs, secreting the same signal to attract lung-tropic circulating tumor cells. Second, antitumor and pro-tumor neutrophils are selectively recruited to the dormant scaffolds and lungs, respectively, responding to distinct groups of chemoattractants to establish activated or suppressive immune environments that direct different fates of cancer cells.

Abstract

Abstract The present study aimed to identify the bioactive constituents in the chloroform extract of H. spicatum rhizomes (HS-RCLE), further evaluated for its in-vitro pesticidal activities validating via molecular docking techniques. GC/MS analysis of HS-RCLE identified 14 compounds contributing 84.1 % of the total composition. The extract was dominated by oxygenated sesquiterpenes (43.1 %) with curcumenone (25.2 %) and coronarin E (14.8 %) as the major compounds. The extract recorded 89.4 % egg hatchability inhibition and 82.6 % immobility of Meloidogyne incognita, 66.7 % insecticidal activity on Spodoptera litura, 100 % phytotoxic activity on Raphanus raphanistrum seeds, and 74.7 % anti-fungal activity on Curvularia lunata at the respective highest dose studied. The biological activities were furthermore validated by using docking studies on certain proteins/enzymes namely acetylcholinesterase (PBD ID: IC2O), carboxylesterase (PDB ID: 1CI8), acetohydroxyacid synthase (PBD ID: 1YHZ) and trihydroxy naphthalene reductase (PBD ID: 3HNR). The bioactivity of the major constituents of the extract was predicted with the help of in silico PASS studies. HS-RCLE was observed to be a viable alternative source of natural pesticidal agents and paves the way for further studies on its mechanistic approaches and field trials to ascertain its pesticidal studies.

41. A Hands-On Introduction to Machine Learning for Calculus Students

Author

Ravi, M. S.

Abstract

This article shows how the exciting new field of Machine Learning can be effectively introduced in a standard calculus sequence, once the students have been introduced to functions of several variables. This is an opportunity to engage students in a discussion of an application of calculus to an emerging field that the students encounter in their everyday life; either through online advertising, or through increasingly sophisticated applications like image recognition, computer voice transcription, etc. In addition to the 'cool' factor which can help engage the students, this application could appeal to students outside the traditional STEM disciplines. In this article the author demonstrates how this application can illustrate the central mathematical ideas that students should gain from studying calculus.

Abstract

Background and Objectives: Tibia is a superficial long bone, with one third of its surface being subcutaneous. An increasing incidence of road traffic accidents, farm accidents, gunshot wound predisposes it for open fracture. Open fractures of the tibia are the most common open long bone fractures. High-energy trauma is the primary mechanism of injury, with over 50% of cases being attributed to road traffic accidents are frequently contaminated. The treatment of open tibia fractures is still controversial. This prospective study was conducted at a tertiary care trauma center to evaluate the functional outcome and complications following primary debridement and nailing in type I to type IIIA open tibia fractures. Materials and Methods: A total of 30 patients diagnosed with open tibial diaphyseal fractures, who underwent primary debridement and fixation with intramedullary interlocking nail were included in the study and type III B, type III C open fractures were excluded. Patients were followed for a period of 12 months and assessed using Modified Ketenjian criteria and Johner − Wruhs' criteria. Results: Out of 30 patients who underwent primary nailing for open tibia fractures, 66.67% had excellent, 26, 67% good, and 6.66% of patients had fair results. 93.33% of the patients had union within 9 months and 6.66% of the cases had delayed union. Conclusion: Primary intramedullary interlocking nailing in open tibia fractures is a good treatment option, it aids early patient mobilization and early resume to work. It avoids multiple surgical procedures and promotes early fracture union.
