Summary1)When the development of one or more blastomeres of the eggs ofAscaris megalocephala in 2- or 4-cell stages, is prevented by exposure to the rays of ultra-violet light for 6 to 8 hours, the remaining blastomeres produce the same cells and cell-groups as they would have produced had the whole egg developed normally.2)When one blastomere of a 4-cell stage is prevented from developing, the other three may produce an approximately normal 3/4 embryo, defective as to the cells and cell-groups…

TLDR
I find that in the first segmentation division, the enlarged masses of chromatin which are similar to the cast off ends in the somatic cells of normal segmentation, may or may not take part in nuclear reconstruction and the succeeding division; that the chromatin of the first segments is more greatly disturbed than in the divisions which follow.

Embryogenesis in C. elegans after elimination of individual blastomeres or induced alteration of the cell division order

TLDR
By ablating early blastomeres it is demonstrated here that the establishment of certain cell lineages is not necessary for the generation of a hatching juvenile, and the invariant pattern of early nematode embryogenesis is not a necessary prerequisite for normal development.

Phylum-wide transcriptome analysis of oogenesis and early embryogenesis in selected nematode species

TLDR
Female-specific expression of potential polarity associated genes during gonad development and oogenesis in the Enoplean nematode Romanomermis culicivorax is identified and demonstrates that the molecular machinery controlling oogenesis and embryogenesis in nematodes must be regulated differently in non-Caenorhabditis Nematodes, as crucial controlling components of Wnt and sex determination signaling are absent in these species.

Evolution of Cellular Pattern Formation during Early Nematode Embryogenesis

TLDR
This review focuses on cellular pattern formation and cell fate assignment during early development in nematodes and concludes that the “standard pattern” as found in the model system C. elegans constitutes only one of the many ways to construct a nematode.

Theodor and Marcella Boveri: chromosomes and cytoplasm in heredity and development

TLDR
The contributions of Theodor B overi and his co-worker, Marcella O'Grady Boveri, to the understanding of heredity and development go beyond the localization of the Mendelian hereditary factors onto the chromosomes.

Ultraviolet sensitivity of WASH (water, sanitation, and hygiene) -related helminths: A systematic review

TLDR
It is confirmed that further research is required to produce detailed recommendations for household or community scale UV-C LED or solar disinfection of water for preventing helminthiases and there has been very little research into the UV sensitivity of helminths.

Zur Kenntnis der Mitose III

TLDR
Die bei stärkerer Bestrahlung nach einem mitosenfreien Intervall sich abrundenden and zerfallenden Zellen folgen in ihrem zeitlichen Auftreten dem Wachstumsrhythmus and müssen deshalb als die zu ihrer Zeit fälligen Mitosen gewertet werden.
