Craniometrics and Ventricular Access: A Review of Kocher'S, Kaufman'S, Paine'S, Menovksy'S, Tubbs', Keen'S, Frazier'S, Dandy'S, and Sanchez'S Points
Oper Neurosurg (Hagerstown) 2020 May 1;18(5):461-469.PMID:31420653DOI:10.1093/ons/opz194.
Intraventricular access is frequently required during neurosurgery, and when neuronavigation is unavailable, the neurosurgeon must rely upon craniometrics to achieve successful ventricular cannulation. In this historical review, we summarize the most well-described ventricular access points: Kocher'S, Kaufman'S, Paine'S, Menovksy'S, Tubbs', Keen'S, Frazier'S, Dandy'S, and Sanchez'S. Additionally, we provide multiview, 3-dimensional illustrations that provide the reader with a novel understanding of the craniometrics associated with each point.
Finkelstein'S Test Is Superior to Eichhoff'S Test in the Investigation of de Quervain'S Disease
J Hand Microsurg 2018 Aug;10(2):116-118.PMID:30154628DOI:10.1055/s-0038-1626690.
Introduction de Quervain'S tenosynovitis is a common pathologic condition of the hand. Finkelstein'S test has long been considered to be a pathognomonic sign of this diagnosis, yet most clinicians and instruction manuals erroneously describe what is in fact the Eichhoff'S test, which is thought to produce similar pain by tendon stretching in a normal wrist. The purpose of this study was to compare Finkelstein'S test with Eichhoff'S test in asymptomatic individuals. Materials and Methods Thirty-six asymptomatic participants (72 wrists) were examined using both Finkelstein'S and Eichhoff'S tests with a minimum interval of 24 hours between the tests. Results The results showed that Finkelstein'S test was more accurate than Eichhoff'S test. It demonstrated higher specificity, produced significantly fewer numbers of false-positive results, and also caused significantly less discomfort to patients. Conclusion This study recommends Finkelstein'S test as the clinical examination of choice for the diagnosis of de Quervain'S disease.
Temperature dependence of the high-spin S2 to S3 transition in Photosystem II: Mechanistic consequences
Biochim Biophys Acta Bioenerg 2019 Jun 1;1860(6):508-518.PMID:31059676DOI:10.1016/j.bbabio.2019.05.001.
The Mn4CaO5-cluster in Photosystem II advances through five oxidation states, S0 to S4, before water is oxidized and O2 is generated. The S2-state exhibits either a low-spin, S = 1/2 (S2LS), or a high-spin state, S = 5/2 (S2HS). Increasing the pH favors the S2HS configuration and mimics the formation of TyrZ in the S2LS-state at lower pH values (Boussac et al. Biochim. Biophys. Acta 1859 (2018) 342). Here, the temperature dependence of the S2HS to S3 transition was studied by EPR spectroscopy at pH 8.6. The present data strengthened the involvement of S2HS as a transient state in the S2LSTyrZ → S2HSTyrZ → S3TyrZ transition. Depending on the temperature, the S2HS progresses to S3 states exhibiting different EPR properties. One S3-state with a S = 3 signal, supposed to have a structure with the water molecule normally inserted in S2 to S3 transition, can be formed at temperatures as low as 77 K. This suggests that this water molecule is already bound in the S2HS state at pH 8.6. The nature of the EPR invisible S3 state, formed down to 4.2 K from a S2HS state, and that of the EPR detectable S3 state formed down to 77 K are discussed. It is proposed that in the S2LS to S3 transition, at pH < 8.6, the proton release (Sugiura et al. Biochim. Biophys. Acta 1859 (2018) 1259), the S2LS to S2HS conversion and the binding of the water molecule are all triggered by the formation of TyrZ.
Synthesis and evaluation of radioiodinated (S,S)-2-(alpha-(2-iodophenoxy)benzyl)morpholine for imaging brain norepinephrine transporter
Eur J Nucl Med Mol Imaging 2006 Jun;33(6):639-47.PMID:16523308DOI:10.1007/s00259-005-0017-y.
Purpose: Abnormality of the brain norepinephrine transporter (NET) has been reported in several psychiatric and neuronal disorders. Since NET is an important target for the diagnosis of these diseases, the development of radiopharmaceuticals for imaging of brain NET has been eagerly awaited. In this study, we synthesized (S,S)-2-(alpha-(2-iodophenoxy)benzyl)morpholine [(S,S)-IPBM], a derivative of reboxetine iodinated at position 2 of the phenoxy ring, and evaluated its potential as a radiopharmaceutical for imaging brain NET using SPECT. Methods: (S,S)-(123/125)I-IPBM was synthesized in a halogen exchange reaction. The affinity and selectivity of (S,S)-IPBM for NET was measured by assaying the displacement of (3)H-nisoxetine and (S,S)-(125)I-IPBM from the binding site in rat brain membrane, respectively. The biodistribution of (S,S)-(125)I-IPBM was also determined in rats. Furthermore, SPECT studies with (S,S)-(123)I-IPBM were carried out in the common marmoset. Results: (S,S)-(125)I-IPBM was prepared with high radiochemical yields (65%) and high radiochemical purity (>98%). (S,S)-IPBM showed high affinity and selectivity for NET in the binding assay experiments. In biodistribution experiments, (S,S)-(125)I-IPBM showed rapid uptake in the brain, and the regional cerebral distribution was consistent with the density of NET. The administration of nisoxetine, a selective NET-binding agent, decreased the accumulation of (S,S)-(125)I-IPBM in the brain, but the administration of selective serotonin transporter and dopamine transporter binding agents caused no significant changes in the accumulation. Moreover, (S,S)-(123)I-IPBM allowed brain NET imaging in the common marmoset with SPECT. Conclusion: These results suggest that (S,S)-(123)I-IPBM is a potential SPECT radiopharmaceutical for imaging brain NET.
Impact of sporadic reporting of poultry Salmonella serovars from selected developing countries
J Infect Dev Ctries 2015 Jan 15;9(1):1-7.PMID:25596565DOI:10.3855/jidc.5065.
This review documents the sporadic reporting of poultry Salmonella serovars in South Africa, Egypt, Indonesia, India, and Romania, five countries selected based on the importance of their distribution in different regions of the world and their cumulative significant population size of 1.6 billion. South Africa reported contamination of its poultry carcasses by S. Hadar, S. Blockley, S. Irumu, and S. Anatum. Results from Egypt showed that S. Enteritidis and S. Typhimurium were predominant in poultry along with other non-typhoid strains, namely S. Infantis, S. Kentucky, S. Tsevie, S. Chiredzi, and S. Heidelberg. In Indonesia, the isolation of Salmonella Typhi was the main focus, while other serovars included S. Kentucky, S. Typhimurium, and S. Paratyhi C. In India, S. Bareilly was predominant compared to S. Enteritidis, S. Typhimurium, S. Paratyphi B, S. Cerro, S. Mbandaka, S. Molade, S. Kottbus, and S. Gallinarum. Romania reported two Salmonella serovars in poultry that affect humans, namely S. Enteritidis and S. Typhimurium, and other non-typhoid strains including S. Infantis, S. Derby, S. Colindale, S. Rissen, S. Ruzizi, S. Virchow, S. Brandenburg, S. Bredeney, S. Muenchen, S. Kortrijk, and S. Calabar. The results showed the spread of different serovars of Salmonella in those five developing countries, which is alarming and emphasizes the urgent need for the World Health Organization Global Foodborne Infections Network (WHO-GFN) to expand its activities to include more strategic participation and partnership with most developing countries in order to protect poultry and humans from the serious health impact of salmonellosis.
