#1
Jaime A Teixeira da Silva
The Paolo Macchiarini case has several ethical ramifications. Professor Macchiarini, formerly of the Karolinska Institutet (KI), became famous for the tracheal surgeries he conducted between 2008 and 2014. His rapid rise to fame was followed by an almost equally rapid fall from grace as official reports, articles in newspapers and television programmes revealed several aspects related to misconduct in his curriculum vitae, professional practices and publishing-related activity. Formal misconduct reports issued by four KI co-workers in late 2014, then again in 2016, coupled with social scandals, including the tricking of a famous US television newscaster into a false marriage, a previous arrest in Italy for apparent bribery, and acute narcissism, all tainted Macchiarini's legend...

Three species of Opisthomonorcheides Parukhin, 1966 are reported for the first time from Indonesian waters: O. pampi (Wang, 1982) Liu, Peng, Gao, Fu, Wu, Lu, Gao & Xiao, 2010 and O. ovacutus (Mamaev, 1970) Machida, 2011 from Parastromateus niger (Bloch), and O. decapteri Parukhin, 1966 from Atule mate (Cuvier). Both O. pampi and O. ovacutus can now be considered widespread in the Indo-Pacific region, with earlier records of these species being from Fujian Province, China and Penang, Malaysia, respectively. We redescribe O...

The voice is an important part of human identity. The voice is susceptible to impact of hormons mainly sexual hormons. The larynx is one of secondary sex characacteristics. Disorders of voice pose serious obstacle to full social integration in male to female and female to male transsexuals. The causes of transsexuality are still a matter of considerable debate. Now it is considered that, big nucleus suprachiasmaticus in the hypothalamus may be a cause of transsexuality. The aim of phonosurgery in transsexual patients is to gain acceptable voice by the patients...

One of the legacies of the now retired Caltech Submillimeter Observatory (CSO) is presented in this paper. We measured for the first time the emission of the giant planets Jupiter and Saturn across the 0.3 to 1.3 mm wavelength range using a Fourier Transform Spectrometer mounted on the 10.4-meter dish of the CSO at Mauna Kea, Hawaii, 4100 meters above sea level. A careful calibration, including the evaluation of the antenna performance over such a wide wavelength range and the removal of the Earth's atmosphere effects, has allowed the detection of broad absorption lines on those planets' atmospheres...

Classic gastroenterological diagnostic tools have proven to be insufficient in identifying the causal relationship between extra-esophageal symptoms and presumed pathological reflux activity. Some new methodological approaches, such as functional endoscopy (video panendoscopy, VPE), are considered to be helpful. However, there are currently no data objectively verifying the success of this method. In a previous study, we found a good correlation between the reflux symptom index (RSI) according to Belafsky and endoscopic findings...

The strawberry (Fragaria x ananassa Dutch.), is the only vegetable belonging to the rosacea family. All strawberry species have now emerged from wild species and belong to the genus Fragaria, being that this genus presents more than 45 described species, and only 11 are considered natural species. Due to the octoploid nature of strawberry and its variability after hybridization, selecting one or more characters may result in unfavorable genotypes and even the exclusion of promising ones, because negative genetic correlations have been observed among them that cause inefficient selection...

Mei-Fei Yueh, Shujuan Chen, Nghia Nguyen, Robert H Tukey
Hyperbilirubinemia, caused by the accumulation of unconjugated bilirubin, is one of the most common clinical diagnoses in both premature and term newborns. Owing to the fact that bilirubin is metabolized solely through glucuronidation by UDP-glucuronosyltransferase (UGT) 1A1, it is now known that immaturity of UGT1A1 in combination with overproduction of bilirubin during the developmental stage acts as a bottleneck to bilirubin elimination and predisposes the infant to high TBS levels. While neonatal jaundice is mostly benign, excessively high levels of serum bilirubin in a small percentage of newborns can cause bilirubin-induced neurologic dysfunction (BIND), potentially leading to permanent brain damage, a condition known as kernicterus...

A major biochemical goal is the ability to mimic nature in engineering highly specific protein-protein interactions (PPIs). We previously devised a computational interactome screen to identify eight peptides that form four heterospecific dimers despite 32 potential off-targets. To expand the speed and utility of our approach and the PPI toolkit, we have developed new software to derive much larger heterospecific sets (≥24 peptides) while directing against antiparallel off-targets. It works by predicting Tm values for every dimer on the basis of core, electrostatic, and helical propensity components...

Interactions between bacteria and protists are essential to the ecosystem ecology of fens. Until now, however, there has been almost no information on how restoration procedures in carbonate fens affect the functioning of microbial food webs. Changes in vegetation patterns resulting from restoration may take years to be observed, whereas microbial processes display effects even after short-term exposure to changes in environmental conditions caused by restoration. Therefore, microbial processes and patterns can be used as sensitive indicators of changes in environmental conditions...

INTRODUCTION: The vacuum assisted closure device (VAC) improves wound-healing when utilized as a bolster to secure split thickness skin grafts (STSG). Patients typically remain hospitalized for VAC therapy; however, home VACs (hVAC) are now available. Limited studies examine burns treated with hVAC as a STSG bolster. METHOD: A retrospective study of records from an ABA verified regional burn center was conducted over 23 months. Patients included STSGs for burn. Data points included demographics, burn mechanism and location, graft characteristics, hospital length of stay (LOS), and time to heal...

Archaea represents the third domain of life, with the information-processing machineries more closely resembling those of eukaryotes than the machineries of the bacterial counterparts but sharing metabolic pathways with organisms of Bacteria, the sister prokaryotic phylum. Archaeal organisms also possess unique features as revealed by genomics and genome comparisons and by biochemical characterization of prominent enzymes. Nevertheless, diverse genetic tools are required for in vivo experiments to verify these interesting discoveries...

The apple (Malus×domestica) cultivar Honeycrisp has become important economically and as a breeding parent. An earlier study with SSR markers indicated the original recorded pedigree of 'Honeycrisp' was incorrect and 'Keepsake' was identified as one putative parent, the other being unknown. The objective of this study was to verify 'Keepsake' as a parent and identify and genetically describe the unknown parent and its grandparents. A multi-family based dense and high-quality integrated SNP map was created using the apple 8 K Illumina Infinium SNP array...

Pierre-Yves Dupont, Murray P Cox
Lateral gene transfer (or horizontal gene transfer), an atypical mechanism of transferring genes between species, has almost become the default explanation for genes that display an unexpected composition or phylogeny. Numerous methods of detecting lateral gene transfer events all rely on two fundamental strategies: primary structure composition or gene tree/species tree comparisons. Discouragingly, the results of these different approaches rarely coincide. With the wealth of genome data now available, detection of laterally transferred genes is increasingly being attempted in large uncurated eukaryotic datasets...

Incorporating effective smoking cessation interventions into lung cancer screening (LCS) programs will be essential to realizing the full benefit of screening. We conducted a pilot randomized trial to determine the feasibility and efficacy of a telephone-counseling (TC) smoking cessation intervention vs. usual care (UC) in the LCS setting. In collaboration with 3 geographically diverse LCS programs, we enrolled current smokers (61.5% participation rate) who were: registered to undergo LCS, 50-77 years old, and had a 20+ pack-year smoking history...

BACKGROUND: Mammary tumors are the second most common tumors (after skin tumors) in female dogs (Canis lupus familiaris). Tissue Inhibitor of Metlloproteinases-3 (TIMP-3) is a matrix associated endogenous inhibitor of Matrix Metalloproteinases (MMPs). Cancer metastasis occurs as a result of imbalance between MMPs and TIMPs. TIMP-3 is involved significantly in regulation of MMPs as well as progression of canine mammary tumor. OBJECTIVE: The present study was conducted to identify the structural and functional relationship between TIMP-3 and MMP which can aid in identifying the role of these proteins in canine mammary tumor...

OBJECTIVE: Recently numerous methods have been proposed for estimating average heart rate using photoplethysmography (PPG) during physical activity, overcoming the significant interference that motion causes in PPG traces. We propose a new algorithm framework for extracting instantaneous heart rate from wearable PPG and ECG signals to provide an estimate of heart rate variability during exercise. METHODS: For ECG signals we propose a new spectral masking approach which modifies a particle filter tracking algorithm, and for PPG signals constrains the instantaneous frequency obtained from the Hilbert transform to a region of interest around a candidate heart rate measure...

Long non-coding RNAs (lncRNAs) have now become the new hotspots in an ocean of diseases including osteosarcoma. The function of taurine up-regulated gene 1 (TUG1) and its working mechanism in osteosarcoma remain unclear. In our research, we found that TUG1 was elevated and correlated with a poor prognosis in osteosarcoma patients. Also, the following functional experiment showed that decreased TUG1 could remarkably inhibit osteosarcoma cell migration and invasion, indicating that TUG1 functioned as an oncogene in osteosarcoma...

From 1814 to 1831, the Prussian naturalist Friedrich Sellow collected 263 mammals in Brazil and Uruguay. Upon receiving the specimens, the curator of the Berlin Zoological Museum, Martin Lichtenstein, removed the original labels and replaced with ones containing more generalized locations. As a consequence, several type specimens have now dubious type localities. We examined these types as well as geographically restricted mammals collected by Sellow. In some cases, there are inconsistencies between the specimen label and the collection catalog regarding the collecting locality...
