Imprinting Mechanisms [PDF]

open access: yesGenome Research, 1998
A number of recent studies have provided new insights into mechanisms that regulate genomic imprinting in the mammalian genome. Regions of allele-specific differential methylation (DMRs) are present in all imprinted genes examined. Differential methylation is erased in germ cells at an early stage of their development, and germ-line-specific ...

Mechanization, Automation, Robotization and Digitalization: Conceptual Clarification and Systematization

open access: yesСельскохозяйственные машины и технологии, 2023
The paper highlights the importance of clarifying scientific terminology to delineate the exclusion of humans from technical systems, in particular the concepts such as «mechanization,» «automation,» «robotization,» and «digitalization» that are commonly

Smaller is better: nanobodies meet NMR

open access: yesFEBS Letters, EarlyView.
Nanobodies are single‐domain antigen‐binding fragments derived from camelid heavy chain antibodies. Their small size, high stability, and exceptional specificity make nanobodies uniquely useful probes for NMR studies of protein dynamics, transient conformational states, and protein–protein interactions.

Productivity and Quality Sugarcane Broth at Different Soil Management

open access: yesAgronomy, 2023
The quality of sugarcane broth can be affected by soil management. In compacted soils the productivity is reduced, and the raw material is poor. This research aimed to evaluate productivity and quality of sugarcane for four soil management types: (CT ...

Developmental programmes drive cellular plasticity, disease progression and therapy resistance in lung adenocarcinoma

open access: yesMolecular Oncology, EarlyView.
This study shows that lung adenocarcinomas exploit developmental branching morphogenesis to acquire a therapy resistant basal‐like tumour cell state. This process was found to be regulated by combined TP53 loss‐of‐function and type‐I interferon signalling, identifying a novel axis for biomarker and therapeutic target discovery.

Assessment of mechanization status for some major crop value chains in Ghana

open access: yesAcademy Journal of Science and Engineering, 2023
Mechanization of agriculture is widely accepted as a means to raise agricultural output and ensure sufficient food supplies. Previous failed attempts to mechanize Ghana's agriculture have been linked to a failure on the part of policymakers to recognize ...

Experimental Study and Engineering Application of the Spatial Reticulated Grid Bolt-Shotcrete Support Structure for Excavation Tunnels

open access: yesApplied Sciences, 2022
In view of the problems of rapid construction and deformation control of large cross-section tunnels in complex urban environments, the concept of “timely high-strength support” was put forward to form strong support over time and bear the load of ...

Loss of IGF‐1R impairs DNA‐PKcs recruitment to chromatin leading to defective end‐joining

open access: yesMolecular Oncology, EarlyView.
IGF‐1R promotes radioresistance by facilitating DNA‐PKcs recruitment to chromatin, enabling non‐homologous end‐joining (NHEJ) repair of double‐strand breaks. Inhibition or loss of IGF‐1R disrupts this recruitment to damage sites, driving compensatory reliance on microhomology‐mediated end‐joining (MMEJ) repair.

Mechanisms of Teratogenesis [PDF]

open access: yesAmerican Journal of Anatomy, 1972
Man’s early pictorial and written records make it clear that he was aware of and curious about the structural defects that from birth afflicted some of his fellow men. His attitudes about these congenital variants have ranged widely in different cultures: from romanticizing them in mythology, to using them as portent of coming events, to accepting them
