A Framework For Digital Energy Modulation And Translation In Projectional X-Ray Imaging, Richard R. Wargo

Theses and Dissertations

In projectional X-ray imaging, acquisition energy fundamentally influences subject contrast, image noise, and radiation dose. While dual-energy techniques exploit spectral differences to optimize contrast and enable material separation, acquiring multiple images of the same anatomy often requires additional exposures and increased system complexity.

This dissertation presents a framework for digital energy modulation (DEM), in which computational models are trained to translate projection images between energy domains without requiring additional X-ray acquisitions. DEM is conceived as a generalizable strategy for controlled contrast modulation in projection imaging, with potential applications in image optimization, radiation therapy alignment, and dual-energy applications.

The framework was …

Myelin Oligodendrocyte Glycoprotein Antibody-Associated Disease Incidentally Diagnosed During Post-Stroke Rehabilitation: A Case Report, Ching-Yun Liao, Chung-Hao Chao, Chih-Chin Hsu

Rehabilitation Practice and Science

背景

髓鞘少突膠質細胞糖蛋白抗體相關疾病（MOGAD）是一種罕見的自體免疫發炎性疾病，主要涉及中樞神經系統（CNS），其主要特徵是視神經、腦部和脊髓脫髓鞘。我們報告一例最初疑似復發性中風的病例，該病例在住院中風復健期間最終確診為MOGAD。

病例概要

49歲女性，左側大腦半球梗塞，在中風後復健期間出現多次右側肢體肌力下降伴隨失語症。這些神經功能波動偏離了典型卒中的預期復健軌跡。卒中發作兩個月後行腦部磁振造影（MRI）檢查，結果顯示右側內囊後肢、腦橋及C1脊髓出現多處新發病灶。後續血清學檢查顯示抗髓鞘少突膠質細胞糖蛋白（MOG）IgG抗體陽性，而水通道蛋白4（AQP4）抗體陰性，確診為MOGAD。患者接受了甲潑尼龍治療及充分的復健治療，追蹤期間肌力顯著改善，未見脫髓鞘病灶復發。

結論

本案例凸顯了復健科醫師在早期發現類似中風的神經發炎性疾病的關鍵作用。復健科醫師處於獨特的領先地位，能夠透過持續的功能監測識別「危險信號」；任何偏離預期復健路徑或無法解釋的神經功能波動都應促使醫生進行進一步檢查。早期識別此類非典型模式，並及時進行免疫治療和多學科康復，可以預防永久性功能衰退，並優化長期預後。

BACKGROUND: Stroke leads to complex chronic structural and functional brain changes that specifically affect motor outcomes. The brain predicted age difference (PAD) has emerged as a sensitive biomarker of both sensorimotor and cognitive function after stroke. Our previous study showed a higher global brain PAD associated with poorer motor function after stroke. However, the association between local stroke lesion load, regional brain age, and motor impairment is unclear. This study aimed to investigate the associations between focal lesion damage, regional brain PAD in both hemispheres, and motor outcomes in chronic stroke, and to identify key predictors of motor impairment.

A Chicken Model For Non-Invasive Diagnosis Of Infant Developmental Dysplasia Of The Hip (Ddh) Using Acoustic Transmission Measurements, Aliza Shah

Honors Undergraduate Theses

Developmental dysplasia of the hip (DDH) is a condition characterized by abnormal development and stability of the hip joint. In a healthy infant, the femoral head (ball) fits securely within the acetabulum (socket of the pelvis), allowing for proper joint function. In DDH, the relationship is disrupted, ranging from mild acetabular dysplasia to partial (subluxation) or complete dislocation of the femoral head. This condition represents a range of structural abnormalities that develop during early growth. The integrity of the hip joint is essential for physical mobility, and disruption of this structure can lead to significant functional impairment. DDH may result …

Synthesis And Characterization Of Succinate Dehydrogenase Inhibitors H2/Z14 And C6/Z96 In Order To Combat Small Cell Lung Cancer, Lauren M. Graves

Honors Undergraduate Theses

The use of ubiquinone inhibitors to combat cancer is a recent development in medicinal science and procedures to efficiently synthesize these drugs remain limited. C6/Z96 and H2/Z14, two succinate dehydrogenase inhibitors, have been previously tested in vitro against NSCLC with positive results. Their similarity to ubiquinone is what makes them a strong candidate for a succinate dehydrogenase inhibitor at the ubiquinone binding site. The heterocyclic scaffolds and substituents are proposed to bind strongly through a combination of electronics, hydrogen-bonding, and fit, allowing them to bind well and prove to be more favorable than ubiquinone when competing for the Q-site. By …

Ropinirole-Induced Sleep-Related Behavioral Disturbances And Psychotic Symptoms In Parkinson's Disease: A Case Report, Kareena Arora, Akshatha C. J, Rajesh Raman, Vikrant Arora, Bindu Annigeri, Megha Sadashiv

Digital Journal of Clinical Medicine

Parkinson’s disease (PD) is a progressive neurodegenerative disorder characterized primarily by motor symptoms such as bradykinesia, rigidity, and tremor. Though commonly associated with motor symptoms but can also present with significant non-motor symptoms such as sleep disturbances, psychosis, and cognitive decline. These symptoms may arise spontaneously or be medication-induced. We present the case of a 53-year-old male with Parkinson’s disease who developed nocturnal behavioural disturbances and psychotic features, likely secondary to dopaminergic agonist medication. Symptom resolution followed adjustment of antiparkinsonian medications and the introduction of antipsychotic medication

Spectrum Of Neurodevelopmental Disorders In Children Attending A Developmental Clinic In Dar Es Salaam, Tanzania, Aleya Zulfikar Remtulla, Sumayyah Nasiruddin Saudin, Orujul Hassan, Mariam Noorani

Paediatrics and Child Health, East Africa

Background: Neurodevelopmental disorders (NDDs) in children present significant challenges for healthcare systems globally. In Tanzania, children with NDDs and their families face significant challenges due to late diagnosis, lack of standardized screening tools, widespread stigma and cultural beliefs that deter health-seeking behaviours. Awareness about NDDs is low, and financial constraints further complicate access to necessary medical interventions. The country suffers from a severe shortage of specialized healthcare providers, and general healthcare providers often lack adequate training. Additionally, limited specialized facilities, high treatment costs and insufficient healthcare policies dedicated to NDDs make it difficult to manage these conditions effectively. Understanding the …
