Salmonella invades and replicates inside intestinal epithelial cells both in Salmonella-specific vacuoles and free in the cytosol (hyper-replication). A high-throughput fluorescence microscopy-based protocol is described here to quantify the intracellular phenotypes of Salmonella by two complementary image analyses through ImageJ, reaching single-cell resolution and scoring.

A number of different procedures for preparing nanoparticles for surface analysis are presented (drop casting, spin coating, deposition from powders, and cryofixation). We discuss the challenges, opportunities, and possible applications of each method, particularly regarding the changes in the surface properties caused by the different preparation methods.

We illustrate the application of 1H(15N,αγ)12C resonant nuclear reaction analysis (NRA) to quantitatively evaluate the density of hydrogen atoms on the surface, in the volume, and at an interfacial layer of solid materials. The near-surface hydrogen depth profiling of a Pd(110) single crystal and of SiO2/Si(100) stacks is described.
FAQs
It separates the expansion of female germ cells by mitotic proliferation from the meiotic stages that prepare a cell for reproduction. This distinction helps investigators determine when chromosome number is reduced and when recombination occurs. In genetics, separating these phases clarifies how errors arising during development may influence the genetic constitution and viability of resulting embryos.
Unequal divisions allocate most cellular material to one developing egg while producing smaller polar bodies. Oogenesis Analysis therefore considers both the number and relative cellular contributions of these products, rather than treating every division as equivalent. This pattern is relevant to understanding how a mature oocyte is produced and how abnormal divisions may affect subsequent development.
Meiotic recombination provides a basis for examining how genetic variation is generated, whereas chromosome segregation analysis evaluates whether chromosomes are distributed correctly during meiosis. Studying these processes together helps identify potential sources of aneuploidy, meaning an abnormal chromosome number. Such findings can connect events in oocyte development with reduced embryo viability or developmental abnormalities.
Genomic imprinting is an important genetic feature examined alongside oocyte development because it concerns how inherited genetic information is marked for transmission. Including imprinting in the analysis broadens interpretation beyond chromosome number alone. It helps researchers investigate how maternal contributions may relate to inheritance patterns, reproductive disorders, and developmental outcomes across generations.
In these settings, investigators use the analysis to examine developmental progression, chromosome segregation, recombination, and possible sources of aneuploidy. The same framework supports comparisons involving infertility and maternal-age effects without reducing either condition to a single mechanism. Results can help relate changes in female germ-cell development to reproductive health and the likelihood of developmental abnormalities.
The analysis can provide evidence about how genetic variation arises, how chromosomes are transmitted, and why some embryos may have reduced viability. It also supports investigation of reproductive disorders and developmental abnormalities. Interpreting these outcomes requires connecting cellular events, such as meiotic segregation and unequal division, with inheritance and reproductive health rather than examining them in isolation.
