Lobular carcinoma with cytoplasmic granules
Diagnostic Cytopathology, 2001AbstractWe report on a case of invasive lobular carcinoma of the breast with a previously undescribed cytologic feature. Diff‐Quik‐stained cytologic preparations showed uniform single cells with prominent coarse cytoplasmic granules. Ultrastructurally, the granules showed features suggestive of autophagosomes and/or degenerative mitochondria.

A growth promoting effect of cytoplasmic granules
Experientia, 1953Des membranes chorioallantoidiennes d'embryons de poule traitees par 0,1 ou 0,2 cm3 d'une suspension de «gros granules» (mitochondries) provenants d'un homogenat de foie de grenouille, augmentent en poids sec de 20% environ (valeur rapportee a la croissance normale, ainsi qu'a l'effet du tampon phosphate/salin).

Cytoplasmic granules in exfoliated buccal epithelial cells
Journal of Oral Pathology & Medicine, 1983The cytoplasmic granules in exfoliated epithelial cells of healthy cheek mucosae of seven subjects were studied by means of phase‐contrast microscopy, electron microscopy and histochemistry. An electron microscopic technique was used to study specific granules which had been identified with the light microscope.

Cytoplasmic granules in myogenic cells
Experimental Cell Research, 1955respiration of these amoebae is strongly inhibited by cyanide [4, 10, 111 indicating the presence of a terminal cytochrome oxidase. From our own studies on Tetrahymena geleii (GL) and from the work of Eichel [5] it appears that these organisms also operate on a cytochrome e system. In washed, packed Tetrahymena geleii, observed spectroscopically in the

Cytoplasmic RNA granules, ribostasis, and neurodegeneration
Neurology, 2018The regulation of translation and decay of messenger RNA (mRNA) is a key mechanism for control of gene expression. During transcription in the nucleus, nascent mRNAs assemble with a set of RNA-binding proteins to form messenger ribonucleoprotein particles (mRNPs).

Two types of cytoplasmic granule in Trypanosoma rhodesiense
Experimental Parasitology, 1965Abstract Light microscope studies of Trypanosoma rhodesiense have demonstrated two distinct types of cytoplasmic granule. Type I granules can be fixed with methanol and stained with Giemsa stain. Type II granules can be fixed by OsO 4 vapor but are removed by methanol; they can be demonstrated by phase contrast but cannot be stained with Giemsa ...

Papillary Serous Carcinoma with Basophilic Cytoplasmic Granules
Ultrastructural Pathology, 1985Case HistoryA 69-year-old white female presented with vaginal bleeding and abdominal distention. A uterine cervical biopsy revealed adenocarcinoma. A laparotomy was performed, with a hysterectomy, bilaterial salpingo-oophorectomy, and multiple omental and abdominal lymph node biopsies.

The occurrence of specific cytoplasmic granules in the osteoclast
Journal of Ultrastructure Research, 1967The structure of the osteoclast in the tibiofemoral epiphyses of fetal rats has been studied by electron microscopy. The findings demonstrate the existence of dense specific granules which are apparently isomorphic with the primary lysosomes of soft tissue cell types.

Recruitment of mRNAs to cytoplasmic ribonucleoprotein granules in trypanosomes
Molecular Microbiology, 2007Summary Trypanosomes are outstanding examples of the importance of mRNA metabolism in the regulation of gene expression, as these unicellular eukaryotes mostly control protein synthesis by post‐transcriptional mechanisms.

Studies on the chemical composition of nuclei and cytoplasmic granules
Archives of Biochemistry and Biophysics, 1955Abstract A new method is described for the isolation of nuclei and large and small cytoplasmic granules, using glycerol-water solutions. The nuclei and large and small cytoplasmic granules were isolated from dog kidney, rat kidney, rat spleen, rabbit liver, and rabbit kidney. By a series of extractions there were obtained from each preparation: an “
