Study Question: Does selection for mtDNA mutations occur in human oocytes? Summary Answer: We provide statistical evidence in favor of the existence of purifying selection for mtDNA mutations in human oocytes acting between the expulsion of the first and second polar bodies (PBs). What is Known Already: Several lines of evidence in Metazoa, including humans, indicate that variation within the germline of mitochondrial genomes is under purifying selection...

The apothecary occupied a liminal position in early modern society between profit and healing. Finding ways to distance their public image from trade was a common problem for apothecaries across Europe. This article uses the case of a Bolognese apothecary, Filippo Pastarino, to address the question of how early modern apothecaries chose to represent themselves to political authorities and to the wider public. 'Mercy', alongside 'craft', was a pillar of apothecaries' social identity. By contrast, no matter how central financial transactions ('money') were to their activity, apothecaries did not want to be perceived as merchants...

Fluctuating noise, common in everyday environments, has the potential to mask acoustic cues important for speech recognition. This study examined the extent to which acoustic cues for perception of vowels and stop consonants differ in their susceptibility to simultaneous and forward masking. Younger normal-hearing, older normal-hearing, and older hearing-impaired adults identified initial and final consonants or vowels in noise-masked syllables that had been spectrally shaped. The amount of shaping was determined by subjects' audiometric thresholds...

GaSb nanostructures integrated on Si substrates are of high interest for p-type transistors and mid-IR photodetectors. Here, we investigate the metalorganic chemical vapor deposition and properties of GaSb nanostructures monolithically integrated onto silicon-on-insulator wafers using template-assisted selective epitaxy. A high degree of morphological control allows for GaSb nanostructures with critical dimensions down to 20 nm. Detailed investigation of growth parameters reveals that the GaSb growth rate is governed by the desorption processes of an Sb surface layer and, in turn, is insensitive to changes in material transport efficiency...

PD-L1 is expressed by a subset of patients with metastatic melanoma (MM) with an unfavorable outcome. Its expression is increased in cells resistant to BRAF or MEK inhibitors (BRAFi or MEKi). However, the function and regulation of expression of PD-L1 remain incompletely understood.After generating BRAFi- and MEKi-resistant cell lines, we observed marked up-regulation of PD-L1 expression. These cells were characterized by a common gene expression profile with up-regulation of genes involved in cell movement...

Listeria monocytogenes , a lethal foodborne pathogen, has the ability to resist the hostile food processing environment and thus frequently contaminates ready-to-eat foods during processing. It is commonly accepted that the tendency of L. monocytogenes ' to generate biofilms on various surfaces enhances its resistance to the harshness of the food processing environment. However, the role of biofilm formation in the transferability of L. monocytogenes EGDe remains controversial. We examined the growth of Listeria biofilms on stainless steel surfaces and their effect on the transferability of L...

Complex lesions of the thoracic aorta are traditionally treated in 2 surgical steps with the elephant trunk technique. A relatively new approach is the frozen elephant trunk (FET) technique, which potentially allows combined lesions of the thoracic aorta to be treated in a 1-stage procedure combining endovascular treatment with conventional surgery using a hybrid prosthesis. These are very complex and time-consuming operations, and good results can be obtained only if appropriate strategies for myocardial, cerebral, and visceral protection are adopted...

BACKGROUND: The unrivalled conquests of Genghis Khan (CE c.1162-1227) led to the establishment of the Greater Mongolian Empire. By 1279, the Mongol dynasty controlled a vast Empire which, for the first time in history, unified Europe and China via the famous Silk Road. The ensuing century of peace and stability is referred to by historians as the Pax Mongolica, which facilitated Europe's renaissance and remarkably contributed to the rise of modern medicine and surgery. METHODS: Secondary sources from published literature, primary sources from manuscripts and illustrations courtesy of universities, museum libraries and archives...
