The Vaginal Microbiota, Indah Kencana, Satya Wydya Yenny

Journal of General - Procedural Dermatology and Venereology Indonesia

The vagina is an ecosystem consisting of various species of microorganisms (microbiota) that play important role in maintaining vaginal health. The vaginal ecosystem includes a variety of species classified into aerobic and anaerobic microorganisms which are vaginal microbiota (VMB). In the vagina of a healthy woman, 70% of normal microbiota is dominated by the Lactobacillus species. Lactobacillus is a Gram-positive, anaerobic bacterium, and belongs to the group of lactic acid bacteria (LAB). LAB produces lactic acid which plays a role in maintaining vaginal acidity at pH

Feasible Stenting Of A Large Septal Perforator Providing A Sizeable Coronary Collaterals, Hussam Al Hennawi, Mohammad F. Mathbout,, Abdulrahman Taftafa, Christopher D. Nielsen

Division of Internal Medicine Faculty Papers & Presentations

While coronary artery disease involving the septal perforator branches presents similar to diseases of major coronary arteries, management can present a challenge. Owing to their relatively small size, performing interventional procedures is often impractical in terms of selecting appropriate devices. Although larger septal perforator branches have been managed percutaneously, similar to major vessels, long-term sequelae and clinical effectiveness have been indeterminate. We present our experience in managing a patient with a stenosed septal perforator branch and challenging comorbidities.

Emerging Applications Of Contrast-Enhanced Ultrasound In Trauma, Brenda Tester, Ji-Bin Liu, John R. Eisenbrey, George Koenig

Department of Radiology Faculty Papers

The use of contrast-enhanced ultrasound (CEUS) has expanded over the past decade to include a variety of diagnostic and therapeutic applications. These include urgent clinical situations that require timely diagnosis and subsequent treatment. With the introduction of microbubble ultrasound contrast agents (UCAs), CEUS provides increased sensitivity and specificity over conventional ultrasound. Within the trauma setting, CEUS benefits include point of care imaging and an ability to monitor perfusion in real-time. Additionally, UCAs are non-nephrotoxic, and can be used when contrast enhanced CT is contraindicated. In this review, we discuss recent advancements of CEUS within trauma settings.

Recent Progress In Immunotherapy For Skin Cancer, Fadhli Aulia Mughni, Rinadewi Astriningrum, Aida Sd Hoemardani, Kusmarinah Bramono, Adhimukti T. Sampurna, Agassi Suseno Sutarjo

Journal of General - Procedural Dermatology and Venereology Indonesia

Skin cancer is a global health concern due to its growing incidence and high mortality rate. The most common therapeutic modalities in skin cancer include surgery, radiotherapy, and chemotherapy. However, those therapies do not specifically target cancer cells and may damage healthy tissues. Cancer induces immune response by releasing soluble antigens and danger signals caused by tumor cellular stress or death, while the immune system continuously monitor and control malignant proliferation through cancer immunoediting. Therefore, targeting this mechanism is a promising approach to manage cancer, especially those unresponsive to conventional therapies. Immunotherapy is a specific therapy that manipulates the immune …

Faculty, Staff and Student Publications

EWI2 is a transmembrane immunoglobulin superfamily (IgSF) protein that physically associates with tetraspanins and integrins. It inhibits cancer cells by influencing the interactions among membrane molecules including the tetraspanins and integrins. The present study revealed that, upon EWI2 silencing or ablation, the elevated movement and proliferation of cancer cells in vitro and increased cancer metastatic potential and malignancy in vivo are associated with (i) increases in clustering, endocytosis, and then activation of EGFR and (ii) enhancement of Erk MAP kinase signaling. These changes in signaling make cancer cells (i) undergo partial epithelial-to-mesenchymal (EMT) for more tumor progression and (ii) proliferate …

Viral Infections In Pakistan: Prevalence, Factors Affecting Spread, And Recommendations For Control, Zehra Naseem, Maaha Ayub, Sharaf Ali Shah, Syed Asad Ali, Syed Hani Abidi

Medical College Documents

Pakistan is endemic to a number of viral infections, owing to its humid climate, topographical variation, soaring population, and lack of education and awareness. These viruses may have several different modes of transmission, including respiratory or airborne transmission, sexual transmission, blood-borne, fecal-oral transmission, vector-borne transmission, and transmission following an organ transplant. Although several different microorganisms are responsible for causing these infections, a few viruses are found more commonly in Pakistan and are primarily responsible for causing infections. In this study, we present a review of the most recent studies on different viruses, transmitted through various transmission routes, found commonly in …

The Evolution And Structure/Function Of Bhlh-Pas Transcription Factor Family, Hailey E Edwards, Daniel A Gorelick

Faculty, Staff and Students Publications

Proteins that contain basic helix-loop-helix (bHLH) and Per-Arnt-Sim motifs (PAS) function as transcription factors. bHLH-PAS proteins exhibit essential and diverse functions throughout the body, from cell specification and differentiation in embryonic development to the proper function of organs like the brain and liver in adulthood. bHLH-PAS proteins are divided into two classes, which form heterodimers to regulate transcription. Class I bHLH-PAS proteins are typically activated in response to specific stimuli, while class II proteins are expressed more ubiquitously. Here, we discuss the general structure and functions of bHLH-PAS proteins throughout the animal kingdom, including family members that do not fit …

Pathogenesis Of Tuberculosis: The 1930 Lübeck Disaster Revisited, Peter Donald, Stefan Kaufmann, Stephanie Thee, Anna Maria Mandalakas, Christoph Lange

Faculty, Staff and Students Publications

During the 1930 Lübeck Mycobacterium bovis bacille Calmette–Guérin (BCG) disaster, 251 neonates received three oral BCG doses accidentally contaminated by virulent Mycobacterium tuberculosis; 67 (26.7%) infants died of tuberculosis. BCG reversion to pathogenicity did not occur. Detailed post mortem examinations clarified contested aspects of tuberculosis pathogenesis. Gastrointestinal infection was seldom “silent” and did not cause typical primary pulmonary lesions. In 15 infants, primary pulmonary foci were found but these resulted from vaccine ingestion and aspiration and were not caused by gastrointestinal infection spreading to the lungs without trace of its journey, as claimed by prominent researchers such as Calmette …

Dual-Mode Tumor Imaging Using Probes That Are Responsive To Hypoxia-Induced Pathological Conditions, S A Amali S Subasinghe, Robia G Pautler, Md Abul Hassan Samee, Jason T Yustein, Matthew J Allen

Faculty, Staff and Students Publications

Hypoxia in solid tumors is associated with poor prognosis, increased aggressiveness, and strong resistance to therapeutics, making accurate monitoring of hypoxia important. Several imaging modalities have been used to study hypoxia, but each modality has inherent limitations. The use of a second modality can compensate for the limitations and validate the results of any single imaging modality. In this review, we describe dual-mode imaging systems for the detection of hypoxia that have been reported since the start of the 21st century. First, we provide a brief overview of the hallmarks of hypoxia used for imaging and the imaging modalities used …

Epigenetic variation plays a significant role in normal development and human diseases including cancer, in part through post-translational modifications (PTMs) of histones. Identification and profiling of changes in histone PTMs, and in proteins regulating PTMs, are crucial to understanding diseases, and for discovery of epigenetic therapeutic agents. In this study, we have adapted and validated an antibody-based reverse phase protein array (RPPA) platform for profiling 20 histone PTMs and expression of 40 proteins that modify histones and other epigenomic regulators. The specificity of the RPPA assay for histone PTMs was validated with synthetic peptides corresponding to histone PTMs and by …

Paramedics’ Confidence And Perceived Competence When Attending To Varied Patient Presentations: A Mixed-Method Study, Nicholas J. Waltrich, Jade Sheen, Mathew Ling

Internet Journal of Allied Health Sciences and Practice

Purpose: Paramedics are routinely called to patients presenting with mental health concerns. Previous literature suggests paramedics find this patient group challenging. However, no study has investigated whether paramedics find mental health presentations (MHP) more challenging relative to other patient presentations, or whether certain paramedic variables relate to their perceived ability to manage MHP. This study investigates differences in paramedics’ perceived ability to attend to MHP compared to other patient presentations, and whether their perceived ability is related to their level of experience or location of work (metropolitan or rural). The study also explores paramedic’s experiences and perspectives of MHP. Method: …

Connectomic Analysis Of The Drosophila Lateral Neuron Clock Cells Reveals The Synaptic Basis Of Functional Pacemaker Classes, Orie T. Shafer, Gabrielle J. Gutierrez, Kimberly Li, Amber Mildenhall, Daphna Spira, Jonathan Marty, Aurel A. Lazar, Maria De La Paz Fernandez

Advanced Science Research Center

The circadian clock orchestrates daily changes in physiology and behavior to ensure internal temporal order and optimal timing across the day. In animals, a central brain clock coordinates circadian rhythms throughout the body and is characterized by a remarkable robustness that depends on synaptic connections between constituent neurons. The clock neuron network of Drosophila, which shares network motifs with clock networks in the mammalian brain yet is built of many fewer neurons, offers a powerful model for understanding the network properties of circadian timekeeping. Here, we report an assessment of synaptic connectivity within a clock network, focusing on the …

Regulation Of Age-Associated Insulin Resistance By Mt1-Mmp-Mediated Cleavage Of Insulin Receptor, Xuanming Guo, Pallavi Asthana, Susma Gurung, Shuo Zhang, Sheung Kin Ken Wong, Samane Fallah, Chi Fung Willis Chow, Sijia Che, Lixiang Zhai, Zening Wang, Xin Ge, Zhixin Jiang, Jiayan Wu, Yijing Zhang, Xiaoyu Wu, Keyang Xu, Cheng Yuan Lin, Hiu Yee Kwan, Aiping Lyu, Zhongjun Zhou, Zhao-Xiang Bian, Hoi Leong Xavier Wong

Faculty, Staff and Student Publications

Insulin sensitivity progressively declines with age. Currently, the mechanism underlying age-associated insulin resistance remains unknown. Here, we identify membrane-bound matrix metalloproteinase 14 (MT1-MMP/MMP14) as a central regulator of insulin sensitivity during ageing. Ageing promotes MMP14 activation in insulin-sensitive tissues, which cleaves Insulin Receptor to suppress insulin signaling. MT1-MMP inhibition restores Insulin Receptor expression, improving insulin sensitivity in aged mice. The cleavage of Insulin Receptor by MT1-MMP also contributes to obesity-induced insulin resistance and inhibition of MT1-MMP activities normalizes metabolic dysfunctions in diabetic mouse models. Conversely, overexpression of MT1-MMP in the liver reduces the level of Insulin Receptor, impairing hepatic insulin …

Divergent Outer Retinal Circuits Drive Image And Non-Image Visual Behaviors, Corinne Beier, Ulisse Bocchero, Lior Levy, Zhijing Zhang, Nange Jin, Stephen C Massey, Christophe P Ribelayga, Kirill Martemyanov, Samer Hattar, Johan Pahlberg

Faculty, Staff and Student Publications

Image- and non-image-forming vision are essential for animal behavior. Here we use genetically modified mouse lines to examine retinal circuits driving image- and non-image-functions. We describe the outer retinal circuits underlying the pupillary light response (PLR) and circadian photoentrainment, two non-image-forming behaviors. Rods and cones signal light increments and decrements through the ON and OFF pathways, respectively. We find that the OFF pathway drives image-forming vision but cannot drive circadian photoentrainment or the PLR. Cone light responses drive image formation but fail to drive the PLR. At photopic levels, rods use the primary and secondary rod pathways to drive the …
