Its principal nuclei, the lateral superior olive (LSO) and the medial superior olive (MSO) process interaural time and intensity differences, which are the main cues for sound localization in the horizontal plane. Toothed whales (odontocetes) rely heavily on hearing and echolocation for foraging, orientation, and communication and localize sound with great acuity. The investigation of the SOC in odontocetes provides insight into adaptations to underwater hearing and echolocation. this website However, quantitative anatomical data for odontocetes are currently lacking. We quantified the volume, total neuron number, and neuron density of the LSO of six common dolphins (Delphinus delphis) using the Cavalieri principle and the unbiased stereology optical fractionator. Our results show that the LSO in D. delphis has a volume of 150 + (SD = 27) mm3 , which is on average 69 (SEM = 19) times larger than the LSO in human, or 37 (SEM = 11) times larger than the human LSO and MSO combined. The LSO of D. delphis contains 20,876 ± (SD = 3300) neurons. In comparison, data reported for the human brainstem indicate the LSO has only about ¼ that number but about the same number for the LSO and MSO combined (21,100). LSO neurons range from 21 to 25 μm (minor axis) and from 44 to 61 μm (major axis) in transverse sections. The LSO neuron packing density is 1080 ± (SD = 204) neurons/mm3 , roughly half of the LSO neuron density in human. SMI-32-immunohistochemistry was used to visualize projection neurons in the LSO and revealed the presence of principal, marginal, and multipolar neurons in transverse sections. The distinct morphology of the LSO likely reflects the common dolphin's superb sensitivity to ultra-high frequencies and ability to detect and analyze sounds and their location as part of its underwater spatial localization and echolocation tasks.Thin, metallic wires can easily penetrate the gastrointestinal system if ingested and cause serious cardiac issues in children. We report a pediatric case of such an object that caused cardiac tamponade after lodging in the left ventricle. The wire was extracted without cardiopulmonary bypass and a full recovery was made. Cardiac issues after ingestion of foreign objects are rare but immediate surgery is required for resolution.Several studies have demonstrated the role of high glucose in promoting endothelial dysfunction utilizing traditional two-dimensional (2D) culture systems, which, however, do not replicate the complex organization of the endothelium within a vessel constantly exposed to flow. Here we describe the response to high glucose of micro- and macro-vascular human endothelial cells (EC) cultured in biomimetic microchannels fabricated through soft lithography and perfused to generate shear stress. In 3D macrovascular EC exposed to a shear stress of 0.4 Pa respond to high glucose with cytoskeletal remodeling and alterations in cell shape. Under the same experimental conditions, these effects are more pronounced in microvascular cells that show massive cytoskeletal disassembly and apoptosis after culture in high glucose. However, when exposed to a shear stress of 4 Pa, which is physiological in the microvasculature, human dermal microvascular endothelial cells (HDMEC) show alterations of the cytoskeleton but no apoptosis. This result emphasizes the sensitivity of HDMEC to different regimens of flow. No significant variations in the thickness of glycocalyx were detected in both human endothelial cells from the umbilical vein and HDMEC exposed to high glucose in 3D, whereas clear differences emerge between cells cultured in static 2D versus microfluidic channels. We conclude that culture in microfluidic microchannels unveils unique insights into endothelial dysfunction by high glucose.Lung cancer has the highest incidence and mortality rates among all types of cancer worldwide, and 80%-85% of patients with lung cancer are diagnosed with non-small cell lung cancer (NSCLC), which has 5-year survival rate of only 5% at advanced stages. Development of new therapeutic agents and strategies is required to enhance the treatment efficiency in patients with NSCLC. Metabolic alterations and anticancer effects of plant hormones and their derivatives have not been investigated in NSCLC in vitro and in vivo. The present study investigated the cytotoxic effects of 11 plant hormones and their derivatives against NSCLC cell lines; ortho-topolin riboside (oTR) showed the highest cytotoxicity among all tested compounds against NSCLC cells. Alteration of metabolites and lipids was investigated using gas chromatography-mass spectrometry and nano electrospray ionization-mass spectrometry in oTR-treated NSCLC cells and a xenograft mouse model. oTR reduced amino acid and pyrimidine synthesis in NSCLC cells and xenograft tumors. Moreover, oTR reduced glycolytic function and decreased mitochondrial respiration function by inhibiting glutamine and fatty acid oxidation. Increased levels of phosphatidylcholine, phosphatidylethanolamine, and phosphatidylserine species suggested that oTR might act as a fatty acid oxidation inhibitor. In addition, the increased level of phosphatidylserine species implied that phosphatidylserine-mediated apoptosis occurred in oTR-treated NSCLC cells and xenograft tumor. The antiproliferative and apoptotic effects of oTR were mediated by the reduced p-ERK and p-AKT levels and increased cleaved Caspase-3 levels, respectively. This is the first study to investigate the metabolic alterations and anticancer activity of oTR in in vitro and in vivo models of NSCLC. Our results provide basis for the development of oTR-based therapeutic agent for patients with NSCLC.A total of 1335 outpatients with suspected coronary artery disease and who underwent computed tomography derived fractional flow reserve (FFRCT ) analysis were examined. Only four patients showed reverse increase of FFRCT from the proximal to the distal vessel and all of them had a large ramus artery (RAM). Of all parameters (vessel length, lumen volume, plaque volume, and left ventricular mass), only the bifurcation angle was significantly higher in reverse increase of FFRCT with RAM group (106.0 ± 15.8°) than normal FFRCT with RAM group (82.6 ± 21.7°) and normal FFRCT without RAM group (66.9 ± 21.1°).Desulfovibrio fructosovorans, a sulfate-reducing bacterium, possesses six gene clusters encoding six hydrogenases catalyzing the reversible oxidation of H2 into protons and electrons. Among them, Hnd is an electron-bifurcating hydrogenase, coupling the exergonic reduction of NAD+ to the endergonic reduction of a ferredoxin with electrons derived from H2 . It was previously hypothesized that its biological function involves the production of NADPH necessary for biosynthetic purposes. However, it was subsequently demonstrated that Hnd is instead a NAD+ -reducing enzyme, thus its specific function has yet to be established. To understand the physiological role of Hnd in D. fructosovorans, we compared the hnd deletion mutant with the wild-type strain grown on pyruvate. Growth, metabolite production and consumption, and gene expression were compared under three different growth conditions. Our results indicate that hnd is strongly regulated at the transcriptional level and that its deletion has a drastic effect on the expression of genes for two enzymes, an aldehyde ferredoxin oxidoreductase and an alcohol dehydrogenase. We demonstrated here that Hnd is involved in ethanol metabolism when bacteria grow fermentatively and proposed that Hnd might oxidize part of the H2 produced during fermentation generating both NADH and reduced ferredoxin for ethanol production via its electron bifurcation mechanism.Hydrogels with high mechanical strength and injectability have attracted extensive attention in biomedical and tissue engineering. However, endowing a hydrogel with both properties is challenging because they are generally inversely related. In this work, by constructing a multi-hydrogen-bonding system, a high-strength and injectable supramolecular hydrogel is successfully fabricated. It is constructed by the self-assembly of a monomeric nucleoside molecular gelator (2-amino-2'-fluoro-2'-deoxyadenosine (2-FA)) with distilled water/phosphate buffered saline as solvent. Its storage modulus reaches 1 MPa at a concentration of 5.0 wt%, which is the strongest supramolecular hydrogel comprising an ultralow-molecular-weight (MW less then 300) gelator. Furthermore, it exhibits excellent shear-thinning injectability, and completes the sol-gel transition in seconds after injection at 37 °C. The multi-hydrogen-bonding system is essentially based on the synergistic interactions between the double NH2 groups, water molecules, and 2'-F atoms. Furthermore, the 2-FA hydrogel exhibits excellent biocompatibility and antibacterial activity. When applied to rat molar extraction sockets, compared to natural healing and the commercial hemorrhage agent gelatin sponge, the 2-FA hydrogel exhibits faster degradation and induces less osteoclastic activity and inflammatory infiltration, resulting in more complete bone healing. In summary, this study provides ideas for proposing a multifunctional, high-strength, and injectable supramolecular hydrogel for various biomedical engineering applications.In this article, I consider the framing of trauma as an epigenetic exposure that warrants intergenerational interventions. I draw on ethnographic research conducted in Khayelitsha, Cape Town, South Africa in 2014-15 to illustrate how violence prevention in this context is increasingly framed in epigenetic terms. I show that, in contrast to the anticipatory logic of a programmatic focus on maternal investment as a means to arrest intergenerational cycles of violence, violence produces different infrastructures of anticipation and effects on intergenerational relations. I argue against the speculative conflation of trauma and intergenerational epigenetics, to resist a newly biologized view of the bodily manifestations of apartheid history-in itself a re-inscription of damage, and a form of violence. Drawing on Murphy's concept of distributed reproduction (2017b), I argue for collectivized forms of intervention that aim for accountability and social justice.Concern about the harmful health effects of industrial pollution is increasingly taking on an intergenerational dimension. In environmental health sciences such as toxicology, this has resulted in emphasizing the influence of toxic chemicals, substances, and situations across generations. Toxic relationalities are now being explored through research on gene-environment interaction, including toxicogenomics and epigenetic research through animal experiments and birth cohort studies. Based on fieldwork conducted among reproductive and developmental toxicologists working in Nanjing, China, this article shows how toxicological research both expresses and produces renewed anxieties about "passing down pollution." These toxicological accounts of intergenerational harm problematically work through overly simplistic renderings of reproduction and biological relatedness. But they also have the potential to catalyze creative understandings of toxic relationalities and responsibilities at a moment when making kin is increasingly seen as key to securing livable futures.
