Size‐Modulated Mesoderm‐Endoderm Divergence and Myocardial Cavitation in Micropatterned Cardioids

open access: yesAdvanced Science, EarlyView.
Micropatterned cardioids, CRISPR‐engineered reporter hiPSCs, deep‐tissue imaging, and single‐cell RNA sequencing are integrated to model mesoderm‐endoderm co‐development. Heart‐foregut crosstalk promotes single large cavitation inside cardioids, resembling early heart chamber formation. ABSTRACT The human heart, originating from the splanchnic mesoderm,

An Open‐Source Pipeline for Calcium Imaging and All‐Optical Physiology in Human Stem Cell‐Derived Neurons

open access: yesAdvanced Science, EarlyView.
This work introduces an open‐source all‐optical platform for functional phenotyping of human stem cell‐derived neurons. The system integrates optogenetics, calcium imaging, automated acquisition, and analysis to resolve single‐cell and network activity, enabling longitudinal measurements, disease modeling, and pharmacological screening in preclinical ...

Impact of temperature on karyotype differences in Cynodon dactylon of different ploidy levels at different latitudes

open access: yesBMC Plant Biology
Background Chromosomal karyotype is closely linked to species evolution, adaptability, and environmental responses. As global climate change intensifies, temperature fluctuations critically affect chromosomal behavior, consequently influencing plant ...

THE PECULIARITIES OF CARIOTYPIC EVOLUTION OF MAMMALIS IN THE CAUCASUS MOUNTAINS

open access: yesЮг России: экология, развитие, 2014
. In the present work chromosomal polymorphism is studied on the basis or cariotypes analisis of more than 100 species and intraspecific forms of Mammalia of the Caucasus. Divergence of branches on the phylogenetic trees received on different chromosomal

In silico karyotyping of chromosomally polymorphic malaria mosquitoes in the Anopheles gambiae complex [PDF]

open access: yes, 2019
Chromosomal inversion polymorphisms play an important role in adaptation to environmental heterogeneities. For mosquito species in the Anopheles gambiae complex that are significant vectors of human malaria, paracentric inversion polymorphisms are ...

Clinical, Genetic, and Pathologic Variability in Myelodysplastic Syndromes and Precursor Conditions Across Race, Ethnicity, and Sex

open access: yesAmerican Journal of Hematology, EarlyView.
ABSTRACT The epidemiology of myelodysplastic syndromes/neoplasms (MDS) is challenging to define due to inconsistent reporting, complex diagnostic procedures, and evolving diagnostic criteria. Using the National MDS Natural History Study—a prospective cohort with centrally adjudicated histopathology and genetic variant review—we characterized the ...

Cytogenetic risk stratification in chronic myelomonocytic leukemia

open access: yesHaematologica, 2011
Background The prognostic value of cytogenetic findings in chronic myelomonocytic leukemia is unclear. Our purpose was to evaluate the independent prognostic impact of cytogenetic abnormalities in a large series of patients with chronic myelomonocytic ...

Mammalian karyotype evolution [PDF]

open access: yes, 2009
Kariotip neke jedinke se odnosi na broj, veličinu i izgled njezinih kromosoma. Kromosomi pojedinih vrsta predstavljaju širok spektar raznolikosti, od broja do njihove morfologije.
