Uncertain Risk, Science Experiments, And The Courts, Eric E. Johnson Jan 2021

Uncertain Risk, Science Experiments, And The Courts, Eric E. Johnson

Florida State University Law Review

Legal scholarship has looked at problems of uncertainty- "unknown unknowns"-in a variety of contexts, from financial regulation to national security. This Article, however, focuses on uncertain risk in what may be its most challenging arena: experimental scientific research. Notably, this context imposes a key conceptual hurdle. In other arenas, law and regulation can work to lessen uncertainty. But with science-experiment risk, uncertainty cannot be sidestepped, since going beyond the current state of human knowledge is the whole point of experimental research. Moreover, scienceexperiment risk involves the highest possible stakes, since future experiments could plausibly lead to global catastrophe, even human …

Multisystem Inflammatory Syndrome In Children, Selda Hançerli̇ Törün, Di̇lek Yilmaz Çi̇ftdoğan, Ateş Kara

Turkish Journal of Medical Sciences

As the COVID-19 pandemic continues, children can be infected with the virus that causes COVID-19. Clinical symptoms of children with COVID from China, where the disease was first reported, generally were less severe than adults. However, at the end of April 2020 in Europe, it was observed that some children with SARS-CoV-2 infection developed fever, abdominal pain, shock, myocardial insufficiency and they needed to be taken care of in intensive care unit. This new disease has been called multisystem inflammatory syndrome in children (MIS-C). Although the pathogenesis of MIS-C is unclear, it progresses with signs of multiorgan involvement as a …

Dopamine Transporter Spect Imaging In Parkinson's Disease And Parkinsoniandisorders, Ümi̇t Özgür Akdemi̇r, Hati̇ce Ayşe Tokçaer Bora, Lütfi̇ye Özlem Atay Jan 2021

Dopamine Transporter Spect Imaging In Parkinson's Disease And Parkinsoniandisorders, Ümi̇t Özgür Akdemi̇r, Hati̇ce Ayşe Tokçaer Bora, Lütfi̇ye Özlem Atay

Turkish Journal of Medical Sciences

The dopamine transporter (DAT) imaging provides an objective tool for the assessment of dopaminergic function of presynaptic terminals which is valuable for the differential diagnosis of parkinsonian disorders related to a striatal dopaminergic deficiency from movement disorders not related a striatal dopaminergic deficiency. DAT imaging with single-photon emission computed tomography (SPECT) can be used to confirm or exclude a diagnosis of dopamine deficient parkinsonism in cases where the diagnosis is unclear. It can also detect the dopaminergic dysfunction in presymptomatic subjects at risk for Parkinson's disease (PD) since the reduced radiotracer binding to DATs in striatum is already present in …

Basal And Pentagastrin-Stimulated Calcitonin Cut-Off Values In Diagnosis Of Preoperativemedullary Thyroid Cancer, Emi̇ne Kartal Baykan, Mehmet Erdoğan

Turkish Journal of Medical Sciences

Background/aim: Medullary thyroid cancer (MTC) originates from parafollicular cells (C cell) and produces calcitonin (CT). Basal serum CT was used in the diagnosis and treatment of MTC. If basal CT level is 100 pg/mL or higher, it is likely to have MTC, but if basal CT level is below 10 pg/mL, the probability of developing thyroid disease is low. In cases with basal CT level between 10-100 pg/mL, pentagastrin-stimulated (PS) CT level is studied to evaluate MTC and C cell hyperplasia (CHH). This study aimed to determine cut-off value for basal and PS peak CT level for diagnosis of MTC. …

Background/aim: In the present study we aimed to figure out the effect of metformin on the expression of AMPK-alpha, cyclin D1, and Tp53, and apoptosis in primary breast cancer cells (PBCCs). Materials and methods: PBCCs were treated with two doses of metformin (0 mM, 25 mM). Proliferation was determined by BrdU assay. Real-time PCR was used to assess AMPK-alpha, cyclin D1, and Tp53 gene expressions; apoptotic indexes of PBCCs were analyzed using flow-cytometry. Results: Twenty-four-hour incubation with 25 mM metformin reduced the proliferation of PBCCs. AMPK-alpha gene expression in PBCCs was not affected by 25 mM metformin treatment compared with …

Background/aim: Nonsteroidal antiinflammatory drugs (NSAIDs) including diclofenac, naproxen, ibuprofen, acetylsalicylic acid, and acetaminophen have been shown to have antimicrobial effects on various microorganisms. The aim of this study was to investigate the antibacterial effects of NSAIDs on Staphylococcus aureus. Materials and methods: Susceptibilities of S. aureus strains to NSAIDs with or without antimicrobials (moxifloxacin, vancomycin, ciprofloxacin, clindamycin, and gentamicin) were determined using the microdilution method and disk diffusion test. Expression levels of genes in the presence of drugs were investigated by real-time quantitative RT-PCR (qRT-PCR), and immunoblotting analysis was performed for staphylococcal protein A (SpA). Results: Our results showed that …
