Speech Title: Nanosecond Pulsed Electric Field (nsPEF) Causes Instantaneous Cellular Membrane Modulation by Altering Calreticulin Expression

Abstract: Nanosecond Pulsed Electric Field (nsPEF) is a novel cancer ablation technology which applies high pulsed power into ultra short pulses and causes non-thermal bioeffects on cell membrane. It is hypothesized to open nanopores in the lipid layers on cell membrane but the direct morphological evidence is still lack. This study designed a unique cell capture system to record the instantaneous membrane changes in the early stage of cell death. The melanoma B16-F10 cells and Jurkat T leukemia cells were treated by nsPEF (300 ns, at 2 kV/cm, 4 kV/cm and 8 kV/cm). The morphological changes on plasma membranes caused by nsPEF were snapped in liquid nitrogen after the cells in nsPEF treatment system equipped with free falling track and pulsor. Immediately after a single pulse, the pulsed cells plunged into liquid nitrogen by gravity for scanning electron microscopy (SEM). Beside liquid nitrogen the cell culture media was also used to collect pulsed cells for MTT, apoptosis, cell cycle and CRT expression. The study provides the first hand direct SEM proof of near-real-time cell membrane changes duiring nsPEF-caused cancer cell death. The non-thermal nsPEF induces higher expression of cell surface calreticulin (CRT), a key protein adjusting the lipid raft suspension and trafficking, which contribute to a dynamical membrane rafting, pore perforation and cell death.
Keywords: nanosecond pulsed electric field (nsPEF); membrane perforation; fresh freeze; calreticulin pathway

Speech Title: MR Guided Pulsed High Intensity Focused Ultrasound Enhancement of Docetaxel Combined with Radiotherapy for Prostate Cancer Treatment

Abstract: The purpose of this study is to evaluate the efficacy of the enhancement of docetaxel by pulsed focused ultrasound (pFUS) in combination with radiotherapy (RT) for treatment of prostate cancer in vivo. LNCaP cells were grown in the prostates of male nude mice. When the tumors reached a designated volume by MRI, tumor bearing mice were randomly divided into 7 groups (n=5): (1) pFUS alone; (2) RT alone; (3) docetaxel alone; (4) docetaxel + pFUS; (5) docetaxel + RT; (6) docetaxel + pFUS + RT; and (7) control. MR guided pFUS treatment was performed using a focused ultrasound treatment system (InSightec ExAblate 2000) with a 1.5T GE MR scanner. Animals were treated once with pFUS, docetaxel, RT or their combinations. Docetaxel was given by i.v. injection at 5 mg/kg before pFUS. RT was given 2 Gy after pFUS. Animals were euthanized 4 weeks after treatment. Tumor volumes were measured on MRI at 1 and 4 weeks post-treatment. Results showed that triple combination therapies of docetaxel, pFUS and RT provided the most significant tumor growth inhibition among all groups, which may have a potential for the treatment of prostate cancer due to an improved therapeutic ratio.
Keywords: MRgFUS, docetaxel, RT, prostate cancer, in vivo

Speech Title: Strongyloides in Cerebrospinal Fluid

Abstract: A 45-year-old Latino man with diabetes mellitus type II and recent episode of pneumonia presented to the emergency room with complaint of rectal pain for a week. He was found to have a perirectal abscess and admitted for debridement. Screening HIV test was positive with a T lymphocyte count of 2, a diagnosis previously unknown to the patient. Throughout his course of admission, his mental status deteriorates. Strongyloides was found on cytologic evaluation of his CSF. Strongyloides involvement of CSF is rare and most of them are seen on postmortem examination. The main risk factor for developing hyperinfection and disseminated disease is immunosuppression; which frequently seen in patients with advanced HIV infection or patients received corticosteroid treatment.
Keywords: CSF, HIV, Strongyloides

Speech Title: Identification of Mineral Crystal Nucleators in Bone

Abstract: Biomineralization involves proteins directly in controlling the mineral crystal nucleation/induction, growth, and maturation. We presented these ~300 proteins at the last conference. Among these proteins, here we will show the proteins for inducing mineral crystal deposition, providing new insights into the mechanisms for bone formation and ectopic mineralization such as vascular calcification and for creating mineralized organic matrices that can substitute for bone.

Speech Title: Mouse behavior analysis for Parkinson's disease

Abstract: Automated recognition of mouse behaviours is crucial in studying psychiatric and neurologic diseases, e.g. Parkinson’s disease. To achieve this objective, it is very important to analyse temporal dynamics of mouse behaviours. In this paper, we develop and implement a novel Hidden Markov Model (HMM) algorithm to describe the temporal characteristics of mouse behaviours. In particular, we here propose a hybrid deep learning architecture, where the first unsupervised layer relies on a new spatial-temporal segment Fisher Vector (SFV) encoding both visual and contextual features. Subsequent supervised layers based on our segment aggregated network (SAN) are trained to estimate the state dependent observation probabilities of the HMM. Finally, we evaluate our approach using JHuang’s and our own datasets, and the results show that our method outperforms other state-of-the-art approaches.

Speech Title: Optical Detection of Transcriptional Activities in Single Cells

Abstract: Single cell optical imaging has become a major approach to study mechanisms of transcriptional regulation in higher eukaryotes. I will discuss our recent work in detecting transcriptional activities in cultured mammalian cells by single molecule RNA fluorescence in situ hybridization. We have successfully identified transcription sites of endogenous genes and counted nascent transcripts. We have generated single-copy promoter transgenes by site-specific DNA recombination and have quantitatively analyzed changes in promoter activities in single cells. We have studied the roles of cell cycle progression and transcription factor NF-Y binding in regulating mouse Ccnb1 gene. This work will facilitate single cell analysis on transcriptional regulation in mammals.

Speech Title: Application of Liquid Biopsy in Cancer Research

Abstract: Liquid biopsy has been gaining much attention in cancer research as a complementary or alternative sample to solid tissue biopsy due to its less invasive procedure and the provision of sampling at multiple time points for cancer progress monitoring. In addition, a better representation of tumor heterogeneity can be found in liquid biopsy and faster turnaround time from sample to results can be achieved. This talk will share some applications of liquid biopsy in cancer research, focusing on the circulating cell-free nucleic acids, circulating tumor cells, extracellular vesicles, circulating PIWI-interacting RNAs and microRNA studies. Liquid biopsy will usher in a new era of cancer management, it is a good source for early detection, disease monitoring (including detecting tumor loading, resistance, mutation and recurrence), and perhaps for screening in the future. Furthermore, the facilitation of biomarker detection by digital PCR and next-generation sequencing will also be briefly covered.

Speech Title: Personalised Patient Physiology Monitoring using Bayesian Hierarchical Gaussian Processes

Abstract: With the rapid increase in volume of wearable devices, automated algorithms are employed to label physiological time-series data. The management of chronic diseases can be performed by monitoring continuous time-series vital-sign data (such as blood pressure and heart rate) via low-cost wearable devices. Automated algorithms may then be used with the resulting data to provide early warning of deterioration of the health of an individual. Such algorithms are typically trained for a large population without taking into account the time-variability and inter-subject variability of the data being collected. More...
