Nuclear architecture has never been carefully examined during early mammalian development at the stages leading to establishment of the embryonic and extra-embryonic lineages. Heterogeneous activity of the methyltransferase CARM1 during these stages results in differential methylation of histone H3R26 to modulate establishment of these two lineages. Here we show that CARM1 accumulates in nuclear granules at the 2- to 4-cell stage transition in the mouse embryo, with the majority corresponding to paraspeckles. Read More

In early mammalian embryos, it remains unclear how the first cell fate bias is initially triggered and amplified toward cell fate segregation. Here, we report that a long noncoding RNA, LincGET, is transiently and asymmetrically expressed in the nucleus of two- to four-cell mouse embryos. Overexpression of LincGET in one of the two-cell blastomeres biases its progeny predominantly toward the inner cell mass (ICM) fate. Read More

Previous research showed N-(quinolin-2-ylmethy) butane-1, 4-diamine (QMA), a polyamine analogue, was efficacious in the prevention of oxidative injury in models of cerebral ischemia. The present study manifested that pretreatment with QMA attenuated ischemic damage accompanying up regulation of Nuclear factor erythroid 2‑related factor (Nrf2), Heme oxygenase‑1 (HO‑1), p-ERK and p-Akt in cerebral cortex tissues of middle cerebral artery occlusion (MCAO) rats and oxygen-glucose deprivation (OGD)-treated PC12 cells. Further more, treatment with LY294002 (specific PI3K inhibitor), PD98059 (specific ERK inhibitor), brusatol (specific Nrf2 inhibitor) and SnPP (specific HO-1 inhibitor) deprived almost all the effects of QMA in MCAO rats and OGD-treated PC12 cells.

The development of genetic sexing strains (GSSs) based on classical genetic approaches has revolutionized the application of the sterile insect technique (SIT) against the Mediterranean fruit fly Ceratitis capitata (Wiedemann) (Diptera: Tephritidae). The global use of Mediterranean fruit fly GSS for SIT applications as part of area-wide integrated pest management (AW-IPM) programmes is testimony to their effectiveness. During recent years, transgenic sexing strains (TSSs) have been developed through genetic engineering techniques offering the possibility to produce male-only progeny by introducing female embryonic lethal genes and to increase the efficacy to identify released sterile males by means of the expression of fluorescent transgene markers.

Novel therapeutic options in chronic obstructive pulmonary disease (COPD) require delicate patient selection and thus demand for expert radiologists visually and quantitatively evaluating high-resolution computed tomography (CT) with additional functional acquisitions such as paired inspiratory-expiratory scans or dynamic airway CT. The differentiation between emphysema-dominant and airway-dominant COPD phenotypes by imaging has immediate clinical value for patient management. Assessment of emphysema severity, distribution patterns, and fissure integrity are essential for stratifying patients for different surgical and endoscopic lung volume reduction procedures. Read More

Glycopolymer-coated nanoparticles have attracted significant interest over the past few years, because of their selective interaction with carbohydrate receptors found on the surface of cells. While the type of carbohydrate determines the strength of the ligand-receptor interaction, the presentation of the sugar can be highly influential as the carbohydrate needs to be accessible in order to display good binding. To shine more light on the relationship between nanoparticle structure and cell uptake, we have designed several micelles based on fructose containing block copolymers, which are selective to GLUT5 receptors found on breast cancer cell lines.

Fused aromatic network (FAN) structures are a category of ordered porous polymers that permit the specific fusion of building blocks into extended porous network structures with designed skeletons and pores. One significant feature of FANs is that their structures can be tailorable with fused aromatic rings without rotatable single-bond connectivity. As a result, the geometry and space orientation of the building blocks are easily incorporated to guide the topological expansion of the architectural periodicity. Read More

Aim: To investigate the prevalence, location, and pattern of preexisting microcracks in non-endodontically treated teeth from fresh cadavers. Micro-computed tomography (micro-CT) technology was used as the analytical tool enabling full screening of the root dentine with the teeth retained in their original alveolar socket.
Methodology: As a pilot study and to validate the present method, a series of 4 high-resolution scans were performed on one bone-block specimen with teeth collected postmortem: (i) entire bone-block including the teeth, (ii) second molar tooth extracted atraumatically from the bone-block (iii) extracted tooth dehydrated to induce dentinal defects and (iv) entire bone-block following reinsertion of the extracted tooth into its matching alveolar socket.

By the end of neurogenesis in Drosophila pupal brain neuroblasts (NBs), nuclear Prospero (Pros) triggers cell cycle exit and terminates NB lifespan. Here, we reveal that in larval brain NBs, an intrinsic mechanism facilitates import and export of Pros across the nuclear envelope via a Ran-mediated nucleocytoplasmic transport system. In rangap mutants, the export of Pros from the nucleus to cytoplasm is impaired and the nucleocytoplasmic transport of Pros becomes one-way traffic, causing an early accumulation of Pros in the nuclei of the larval central brain NBs.

In the "Hypothesis" paper entitled "Lanthanides-Based Catalysis in Eukaryotes" (IUBMB Life 2018 Nov;70(11):1067-1075), we analyzed the possibility that Ce -dependent methanol dehydrogenases (MDHs) could be found not only in archaea and bacteria but also in eukaryotic organisms. This hypothesis was based on the observation that MDHs protein sequences carrying the signature of Ce -based active sites could be found in genome-derived proteomes of the eukaryotes Plasmodium yoelii yoelii, Nephila clavipes, Hyalella azteca, Pantholops hodgsonii, and Homo sapiens.

Background: After partial resection of the thyroid gland a second operation referred to as "completion thyroidectomy" may be required if histopathological analysis indicates the presence of differentiated thyroid cancer (DTC). Although there is little evidence it is assumed that the time point of completion thyroidectomy is not critical for oncological prognosis of patients with DTC. We assessed whether patients with total thyroidectomy (TTx) in a two-step procedure have an equal long-term prognosis with regard to disease-specific survival compared to patients immediately undergoing total thyroidectomy in a one-step procedure.
