"Deep Learning For Microscope Image Denoising", Nasreen Buhn, Sriya Adunur, Guy Hagen, Jonathan Ventura

College of Engineering Summer Undergraduate Research Program

In order to avoid damaging live cells, optical microscope imaging must be conducted under low-excitation light intensity and/or short exposure times, resulting in low signal-to-noise ratios (SNR). Deep learning methods offer an effective solution for removing microscope noise, utilizing algorithms that are able to reconstruct finer features in low SNR images. This research explores the denoising capability of several deep learning methods based on PSNR and SSIM. Tested methods include traditional approaches (BMED), supervised learning (CARE and Restormer), and unsupervised methods (Noise2Fast, N2V, SSD-Unsupervised, and SASSID). The Restormer model, which employs an encoder-decoder transformer architecture and progressive learning, stood out …

Molecular Architecture Of Chitin And Chitosan-Dominated Cell Walls In Zygomycetous Fungal Pathogens By Solid-State Nmr, Qinghui Cheng, Malitha C. Dickwella Widanage, Jayasubba Reddy Yarava, Ankur Ankur, Jean Paul Latgé, Ping Wang, Tuo Wang

School of Medicine Faculty Publications

Zygomycetous fungal infections pose an emerging medical threat among individuals with compromised immunity and metabolic abnormalities. Our pathophysiological understanding of these infections, particularly the role of fungal cell walls in growth and immune response, remains limited. Here we conducted multidimensional solid-state NMR analysis to examine cell walls in five Mucorales species, including key mucormycosis causative agents like Rhizopus and Mucor species. We show that the rigid core of the cell wall primarily comprises highly polymorphic chitin and chitosan, with minimal quantities of β-glucans linked to a specific chitin subtype. Chitosan emerges as a pivotal molecule preserving hydration and dynamics. Some …

Same Or Different? Resolution Of Diagnostic Difficulty Of Two Mixed Cell-Type Tumors In Ovarian Pathology., Sarah Ingram, Priyanka Raju Md, Wei Shaw Do, Steve Sowers Pa, Kelly Brenan-Rothschild Md

Transformative Medicine

Introduction: When confronted by two disease processes, physicians in all disciplines are faced with the question: Are they manifestations of a common etiology, or distinct entities co-occurring? Inherent in this dilemma is whether an aberration from normal is even a disease process at all. Tissue pathology plays a key role in resolving this conundrum. Although diagnoses can be challenging, there are various methodologies used in the field of pathology to ascertain whether two tumors are of the same or different origins.

Case Description: This case report reviews two patients with large ovarian neoplasms and surgical pathology revealing histopathological features of …

Bilio-Cecal Stent Migration Presenting As Massive Rectal Bleeding., Lefika Bathobakae, Shady Geris, Mohita Jariwala, Mansi Patel, Jessica Escobar, Ruhin Yuridullah, Kamal Amer, Yana Cavanagh

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Endoscopic biliary stenting is a well-established intervention for the treatment of biliary, hepatic, and pancreatic disorders. The common indications include strictures, neoplasms, stones, infections, and bile leaks. Stents can be occluded, predisposing patients to ascending cholangitis and biliary sepsis. Distal stent migration is another known complication of endoscopic stenting and is usually spontaneous. Bowel perforation, abscesses, bleeding, and pancreatitis are rare complications of distal stent migration and are usually limited to the duodenum. Herein, we describe an extremely rare case of bilio-cecal stent migration presenting as rectal bleeding.

Potential Targeting Mechanisms For Bone-Directed Therapies, Betul Celik, Andrés Leal, Shunji Tomatsu

Department of Pediatrics Faculty Papers

Bone development is characterized by complex regulation mechanisms, including signal transduction and transcription factor-related pathways, glycobiological processes, cellular interactions, transportation mechanisms, and, importantly, chemical formation resulting from hydroxyapatite. Any abnormal regulation in the bone development processes causes skeletal system-related problems. To some extent, the avascularity of cartilage and bone makes drug delivery more challenging than that of soft tissues. Recent studies have implemented many novel bone-targeting approaches to overcome drawbacks. However, none of these strategies fully corrects skeletal dysfunction, particularly in growth plate-related ones. Although direct recombinant enzymes (e.g., Vimizim for Morquio, Cerezyme for Gaucher, Elaprase for Hunter, Mepsevii for …

Clinical Practice in Athletic Training

The Athletic Training Milestones (AT Milestones) were developed as an evaluation tool to capture the breadth and depth of athletic training knowledge, skills, and behavior. However, it is unclear whether athletic training programs are implementing this tool or how they are implementing it to gauge the clinical progression of students or residents in athletic training. We aimed to explore the perceptions and use of the AT Milestones among educators in athletic training programs. We used a cross-sectional, web- based survey with open-ended questions to collect data from athletic training programs on if and how they implement the AT Milestones at …

Using Machine Learning To Determine A Functional Classifier Of Reward Responsiveness And Its Association With Adolescent Psychiatric Symptomatology, Robert James Richard Blair, Johannah Bashford-Largo, Ahria Dominguez, Matthew Dobbertin, Karina S. Blair, Sahil Bajaj

Center for Brain, Biology, and Behavior: Faculty Publications

Background. Machine learning (ML) has developed classifiers differentiating patient groups despite concerns regarding diagnostic reliability. An alternative strategy, used here, is to develop a functional classifier (hyperplane) (e.g. distinguishing the neural responses to received reward v. received punishment in typically developing (TD) adolescents) and then determine the functional integrity of the response (reward response distance from the hyperplane) in adolescents with externalizing and internalizing conditions and its associations with symptom clusters.

Methods. Two hundred and ninety nine adolescents (mean age = 15.07 ± 2.30 years, 117 females) were divided into three groups: a training sample of TD adolescents …

Introduction: Numerous studies have highlighted cognitive benefits in lifelong bilinguals during aging, manifesting as superior performance on cognitive tasks compared to monolingual counterparts. Yet, the cognitive impacts of acquiring a new language in older adulthood remain unexplored. In this study, we assessed both behavioral and fMRI responses during a Stroop task in older adults, pre- and post language-learning intervention.

Methods: A group of 41 participants (age: 60–80) from a predominantly monolingual environment underwent a four-month online language course, selecting a new language of their preference. This intervention mandated engagement for 90 minutes a day, five days a week. …

Less Activity Means Improved Welfare? How Pair Housing Influences Pinyon Jay (Gymnorhinus Cyanocephalus) Behaviour, London M. Wolff, Jeffrey R. Stevens

Center for Brain, Biology, and Behavior: Faculty Publications

The activity level and specific behaviours exhibited by captive animals are crucial indicators of welfare. Stereotypies, or repetitive behaviours that have no apparent function or goal, are performed by animals experiencing poor conditions in their environment and indicate welfare concerns. Changes in the housing environment in particular may have critical influences on behaviour and welfare. Here, we measured behavioural changes in a captive pinyon jay (Gymnorhinus cyanocephalus) population (n = 10) associated with a shift from single to pair housing. Using automated video processing, we show that pair housing greatly reduced overall activity levels in these birds. The …

A Literature Review Of Pain Control In Osteoarthritis Patients Using Blood Flow Restriction Training, John Gericke, Dakota Pastore, Tyler Pigott

Rowan-Virtua Research Day

Background: Osteoarthritis (OA) is a degenerative disease that mainly affects articular cartilage of joints. OA most commonly affects the knees and causes pain and reduces quality of life in older adults. Blood flow restriction (BFR) occludes arterial and venous flow during exercise using a blood pressure cuff placed on the proximal lower limb. This creates an intramuscular hypoxic environment which promotes muscle hypertrophy. High load training can cause pain and inflammation in knee OA patients due to increased stress. BFR can allow patients with knee OA to use lower loads to achieve beneficial effects of rehabilitation.

Methods: Data was ascertained …

Case Report: Hidden Posterior Dislocation Of The Clavicular Head, David F. Koziel

Rowan-Virtua Research Day

Reported is a case of a 24-year-old male who presented with left shoulder pain and decreased range of motion of the same shoulder upon awakening, diagnosed with a posterior dislocation of the proximal clavicle, with the clavicular head residing in the mediastinum. In the conscious, ambulatory, young adult it is arguably much more common for major bony trauma involving the upper extremity and shoulder to present with pain, deformity, and a known mechanism. This is an example that lacks all three of these characteristics and highlights the importance of details in the physical examination as well as clinical gestalt.

Morel Lavallee Lesion: A Shear Fascia-Nating Soft Tissue Injury, Isaac F. Su, James A. Espinosa, Alan A. Lucerna

Rowan-Virtua Research Day

Morel-Lavallée lesions (MLLs), first described by their namesake, French physician Victor-Auguste-François Morel-Lavallée, in 1863, represent a distinct category of soft-tissue degloving injuries. These injuries occur when a shearing force disrupts the connection between subcutaneous tissue and fascia, severing lymphatic vessels and capillaries, and leading to an encapsulated collection of lymph, blood, and necrotic fat. Because this space is deep and enclosed, the fluid accumulation cannot easily drain or resolve spontaneously and often an inflammatory capsule develops, further inhibiting resorption. Undiagnosed, patients go on to develop chronic pain, infection, skin necrosis, progressive neurovascular deficits, and, in severe cases, potential loss of …
