What do African Citizens of Different Income Levels think of Chinese Investment? 2015-2019 A study of three countries in Africa
No full textThis study focused on determining the relationship between occupation, education and perception on Chinese investment in Kenya, Senegal and Nigeria.
It used a combination of qualitative and quantitative research to determine conclusions. The qualitative research focused on interviews and personal one on one interactions with Africans. The author used publicly available Afrobarometer data for the quantitative study.
The results of the study indicate that there is a correlation between occupation and perception on Chinese influence for all three countries. However, there was no conclusive evidence that there was correlation between education and perception of Chinese influence.

A Case Report of a Gluteus Hematoma Detected on (99m)Tc-MDP Bone Scan
No full textThis is a case report of a gluteal hematoma detected on (99m)Tc-methylene diphosphonate (MDP) whole-body bone scan in a 77-year-old male who had experienced a road traffic accident
Septic Pulmonary Emboli Detected by 18F-FDG PET/CT in a Patient with Central Venous Catheter-Related Staphylococcus aureus Bacteremia
No full textWe describe a case of 18F-FDG PET/CT detecting septic pulmonary emboli in a patient with Staphylococcus aureus catheter-related bloodstream infection (CRBSI). The patient, who had an implantable venous access port for chemotherapy, underwent 18F-FDG PET/CT to diagnose unsuspected infectious foci. The PET/CT examination made it possible to offer a suggestive diagnosis and yielded metastatic infectious foci
Role of 11C-Methionine PET/CT in 99mTc-Sestamibi-Negative Parathyroid Adenoma: A Case Report
No full textWe report a case of 16-year-old female primary hyperparathyroidism patient who underwent cervical ultrasonography and 99mTc-sestamibi single photon emission computed tomography/computed tomography, both of which were negative for parathyroid adenoma. Subsequent 11C-methionine positron emission tomography/CT showed positive focal uptake suggesting parathyroid adenoma, which then was confirmed pathologically
Visualization of Dialysis-Related Amyloid Arthropathy on <sup>18</sup>F-FDG PET-CT Scan
No full textWe report a case of dialysis-related amyloid arthropathy in a patient with end-stage renal disease. It presented in our patient as moderately increased FDG uptake in the amyloid deposition in the periarticular tissues and eroding into adjacent bones
Pulmonary and Liver Toxocariasis Mimicking Metastatic Tumors in a Patient with Colon Cancer
No full textToxocariasis is an uncommon cause of multiple cavitary lung lesions and an ill-defined liver lesion. We herein report a patient with lung and liver toxocariasis, which mimicked metastatic lesions of colon cancer on 18F-FDG PET–CT and chest and abdominal CT performed for cancer staging after diagnosis of colon cancer. The patient was diagnosed with lung and liver toxocariasis by a positive enzyme-linked immunosorbent assay. Lung toxocariasis may occur as multiple cavitary lung lesions, and liver toxocariasis may appear as a solitary ill-defined nodule, which may be misdiagnosed as metastatic tumors. Clinicians should consider toxocariasis when multiple cavitary lung lesions and a solitary ill-defined focal liver lesion are detected, especially in a patient with cancer
Metastatic Pulmonary Calcification Detected on <sup>18</sup>F-FDG PET/CT and <sup>99m</sup>Tc-MDP Bone Scan
No full textMetastatic calcification relates to abnormal calcification resulting from hypercalcemia and can affect soft tissues, skeletal muscle, myocardium, lungs, stomach, kidneys, and blood vessels. We describe a case of metastatic pulmonary calcification in a 71-year-old male, images with 18F-fluorodeoxyglucose (FDG) PET/CT and 99mTc- methylene diphosphonate (MDP) bone scan
High-order synchronization of hair cell bundles
No full textAuditory and vestibular hair cell bundles exhibit active mechanical oscillations at natural frequencies that are typically lower than the detection range of the corresponding end organs. We explore how these noisy nonlinear oscillators mode-lock to frequencies higher than their internal clocks. A nanomagnetic technique is used to stimulate the bundles without an imposed mechanical load. The evoked response shows regimes of high-order mode-locking. Exploring a broad range of stimulus frequencies and intensities, we observe regions of high-order synchronization, analogous to Arnold Tongues in dynamical systems literature. Significant areas of overlap occur between synchronization regimes, with the bundle intermittently flickering between different winding numbers. We demonstrate how an ensemble of these noisy spontaneous oscillators could be entrained to efficiently detect signals significantly above the characteristic frequencies of the individual cells. © The Author(s) 20161
A Case Report of Early-Onset Alzheimer’s Disease Using 18F-FDG PET and 18F-FBB PET
No full textWe describe a 40-year-old female patient who presented with sleep disturbance, intermittent headache, and gradual subjective cognitive decline. 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) showed mild FDG hypometabolism in bilateral parietal and temporal lobes. However, 18F-florbetaben (FBB) amyloid PET revealed diffuse amyloid retention in the lateral temporal cortex, frontal cortex, posterior cingulate cortex/precuneus, parietal cortex, and cerebellum. This finding supports the clinical significance of amyloid imaging in diagnostic work-up of early-onset Alzheimer’s disease (EOAD)
