Within a eukaryotic cell, a membrane-limited body which contains chromosomes and one or more nucleoli (CELL NUCLEOLUS). The nuclear membrane consists of a double unit-type membrane which is perforated by a number of pores; the outermost membrane is continuous with the ENDOPLASMIC RETICULUM. A cell may contain more than one nucleus. (From Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed)
Nuclear morphometry in columnar cell lesions of the breast: is it useful? (1/41)AIMS: To evaluate the nuclear morphometric features of breast columnar cell lesions (CCLs) observed on mammotome core biopsies, to determine if there are significant measurable differences between those with atypia and those without. Correlation with follow-up open excision specimens was made. METHODS: Mammotome core biopsies performed on patients that contained CCLs were derived from the departmental case files. Histological material was reviewed and foci of CCLs demarcated for nuclear morphometric assessment, which was accomplished using an imaging system. Nuclear parameters studied were nuclear area and perimeter, circularity factor and feret's diameter. Statistical analysis used the GraphPad Prism software, with p<0.05 indicating significance. RESULTS: On examination of core biopsies of 40 patients with CCLs, 8 lesions were benign, 4 showed atypical lobular hyperplasia, 8 showed CCLs with nuclear atypia, 19 disclosed atypical ductal hyperplasia (ADH) and 1 showed ductal carcinoma in situ (DCIS). The nuclear area, perimeter and feret's diameter of CCLs with atypia were significantly greater than those without (p = 0.04, 0.03 and 0.019, respectively), whereas no difference was observed in the circularity factor. Follow-up open excision biopsy specimens in 24 patients showed upgrading to DCIS in 40% of cases diagnosed initially with ADH on core biopsy compared with 20% of CCLs with atypia. CONCLUSIONS: Nuclear morphometry in CCLs confirms nuclear size as the key parameter in the assessment of nuclear atypia. Whether it can be potentially used as an adjunctive tool depends on the establishment of appropriate cut-offs. (+info)
Resistance to Alzheimer's pathology is associated with nuclear hypertrophy in neurons. (2/41)This study focuses on the morphometric changes of neurons in asymptomatic Alzheimer's disease (AD), a state characterized by the presence of AD lesions in subjects without cognitive impairment. In autopsy brains, we used stereological methods to compare the cell body and nuclear volumes of anterior cingulate gyrus (ACG) and CA1 hippocampal neurons in asymptomatic AD subjects (n=9), subjects with AD dementia (AD, n=8), mild cognitive impairment (MCI, n=9), and age-matched controls (controls, n=9). In ACG, we observed a significant decrease in the neuronal volume of MCI and AD compared to controls; by contrast, no atrophy was present in asymptomatic AD. Moreover, we found a significant increase in nuclear volume in asymptomatic AD compared to controls (P<0.001), MCI (P<0.01) and AD (P<0.001) brains. Similar results were found in the CA1 region of the hippocampus. This nuclear hypertrophy may represent an early neuronal reaction to Abeta or Tau, or a compensatory mechanism which forestalls the progression of AD and allows the brain to resist the development of dementia.

Nuclear swelling occurs during premature senescence mediated by MAP kinases in normal human fibroblasts. (4/41)Excess thymidine induced premature senescence in normal human fibroblasts (TIG-7), with induction of typical senescence markers. Nuclear swelling, as well as cell swelling, was clearly observed in these senescent cells. Simultaneous addition of MAP kinase inhibitors, U0126, SB203580, and SP60025, effectively suppressed induction of premature senescence and senescence markers. (+info)

Migratory localization of cyclin D2-Cdk4 complex suggests a spatial regulation of the G1-S transition. (8/41)The association of the cyclin D-Cdk (DC) complex with retinoblastoma protein (pRb) is required for the G1-S transition of the cell cycle. Cyclin synthesis, nuclear localization and degradation are control mechanisms for the transition, but regulation of the DC complex nuclear import also contributes to the transition. Analysis of the timing of the G1-S transition in mammalian cell lines revealed acceleration with overexpression of cyclin D2 and Cdk4. Immunolocalization assays revealed that cyclin D2 and Cdk4 formed a complex in the cytoplasm and approached the nucleus. They accumulated on the cytosolic surfaces of the nuclear pores and then were arrested at the nuclear membrane before the nucleus reached a critical size. Finally, the complex was released into the nucleus and colocalized with pRb there, which led to pRb phosphorylation and DNA synthesis. The translocalization depended on the G1-S transition. In contrast, a truncated cyclin D2 that was not able to fully associate with Cdk4 lost the ability for release into the nucleus. This pattern of translocalization suggests a spatial separation of the cyclin D-Cdk complex from pRb and DNA in the nucleus to regulate the G1-S transition. (+info)
A homeostatic mechanism rapidly corrects aberrant nucleocytoplasmic ratios maintaining nuclear size in fission yeast | Crick
Nuclear size scales with cell size across a wide range of cell types. The mechanism by which this scaling is maintained in growing cells remains unclear. Here we investigate the mechanism of nuclear size homeostasis in the simple eukaryote fission yeast, by monitoring the recovery of aberrant nuclear volume to cell volume (N/C) ratios following perturbation. We demonstrate that both high and low N/C ratios correct rapidly, maintaining nuclear size homeostasis. We assess the kinetics of nuclear and cellular growth and of N/C ratio correction and demonstrate that nuclear and cellular growth rates are not directly coupled. We propose that the mechanism underlying nuclear size homeostasis, involves multiple limiting factors implicated in processes including nucleocytoplasmic transport, lipid biogenesis and RNA processing. We speculate that these link cellular size increases to changes in nuclear contents, which in turn lead to changes in nuclear membrane surface area. Our study reveals that there is ...

Prognostic significance of nuclear morphometry in renal cell carcinoma
Although the significance of these preliminary results must not be overstated, nuclear morphometry might provide significant prognostic information in predicting survival and tumours at high risk of progression in RCC.
A Randomized Prospective Study of Lumpectomy Margin Assessment with us by Freya Schnabel, Susan K. Boolbol et al.
BACKGROUND: The presence of tumor cells at the margins of breast lumpectomy specimens is associated with an increased risk of ipsilateral tumor recurrence. Twenty to 30 % of patients undergoing breast-conserving surgery require second procedures to achieve negative margins. This study evaluated the adjunctive use of the MarginProbe device (Dune Medical Devices Ltd, Caesarea, Israel) in providing real-time intraoperative assessment of lumpectomy margins. METHODS: This multicenter randomized trial enrolled patients with nonpalpable breast malignancies. The study evaluated MarginProbe use in addition to standard intraoperative methods for margin assessment. After specimen removal and inspection, patients were randomized to device or control arms. In the device arm, MarginProbe was used to examine the main lumpectomy specimens and direct additional excision of positive margins. Intraoperative imaging was used in both arms; no intraoperative pathology assessment was permitted. RESULTS: In total, 596 patients

In this study we report on the variation in nuclear and cytoplasmic size of intermediate cells in normal cervical smears, in relationship to the week of the menstrual cycle and in relationship to the mode of contraception. A total of 18000 cells from 360 different women was studied. A significant difference in nuclear size of intermediate cells in smears from ovulating women not using contraception was found in comparison with intermediate cells in smears from women using contraceptive pills (ANOVA: F(1.312) = 4.98, p less than 0.02). Also a significant difference in the nuclear size of intermediate cells in smears from women using norgestrel- (or levonorgestrel)-containing formulas compared with lynestrenol-containing formulas was found (ANOVA: F(1.232) = 5.82, p less than 0.01). The influence of exogenous and endogenous hormones on cell populations in cervical smears is discussed. It is concluded that in studies on intermediate cells in cervical smears the contraceptive status of the women has to be

INVESTIGATION OF NUCLEAR ARCHITECTURAL PROTEINS IN ARABIDOPSIS AND TOMATO
Regulation of nuclear morphology in plants results from signaling and physical interactions that span the nuclear envelope. A key regulatory component is a family of Nuclear Matrix Constituent Proteins (NMCPs) that form the plant nuclear lamina. Arabidopsis thaliana contains four NMCP-like proteins, called CROWDED NUCLEI (CRWN). CRWN proteins are necessary for nuclear size and shape maintenance in differentiated cells, where CRWN1 acts as the chief regulator followed by CRWN4. However, the coordination of activities among these paralogous proteins remains unclear. I surveyed nuclear CRWN abundance within crwn single and double mutants using protein immunoblots. I found that plants lacking either CRWN1 or CRWN3 showed a decrease in CRWN4 abundance. Further, loss of CRWN1 along with either CRWN2 or CRWN3 led to a significant reduction in CRWN4 protein levels in the nucleus. Based on these data, the stability of CRWN4 in the nucleus is proposed to depend on an interaction with CRWN1, CRWN2 and ...

Papanicolaou Society of Cytopathology Case of the Month June 2012
Aspiration smears were highly cellular with cohesive clusters and sheets of ductal epithelial cells along with groups of mildly enlarged ductal epithelial cells with increased nuclear to cytoplasmic ratios, mild variation of nuclear size, and inconspicuous nucleoli. Cells had a small to moderate amount of amphophilic cytoplasm. No significant loss of cohesion within the groups of ductal cells was noticed. Scattered bare oval myoepithelial cell nuclei, histiocytes, thin proteinaceous material, and stromal fragments were present. The on-site assessment diagnosis was fibrocystic changes, proliferative type, with atypia . A core biopsy was recommended and was immediately performed. It revealed a proliferation of tubular structures with round and slit-like lumens lined by ductal epithelial cells without significant atypia. The tubules were arranged around fibrillary elastoid material in an infiltrative pattern. Some of the lumens demonstrated florid usual ductal hyperplasia. Cystically dilated ducts ...

Cytonuclear IHC | Indica Labs
The Cytonuclear IHC module measures cell-by-cell IHC positivity for single or multi stain applications. Each cell is measured for cytoplasmic or nuclear positivity of every individual stain as well as the colocalization of different marker combinations. Positive cells are binned and assigned an intensity score (0, 1+, 2+, and 3+) based on stain optical density. The module also reports a variety of other metrics relating to cell/nuclear size and stain intensity. Optionally, the tool can output the complete table of cell data including individual cell sizes and optical density measurements for each stain in each cellular compartment. This module has the option to define specific cell phenotypes according to marker positivity, allowing users to define and count specific cell populations based off of defined positivity and negativity rules.. In the first example shown above, the module is configured to output an intensity markup for a single IHC marker (DAB). Cells below the positivity threshold for ...

Hematological profiles are routinely used to assess the health status of animals. Several methods have been developed for blood-cell counting, but typically they are expensive and/or time-consuming. Here, a free image-processing software, Mizutama, developed for counting cells in photographs of blood smears is presented. Mizutama uses the thresholding method to transform original photographs into grayscale trinary images. Following a number of parameters, Mizutama searches in the image for cells of a given size, with a nucleus size relative to cytoplasm surface area. The software is not only easy, versatile, and intuitive to handle, but is also fast when counting cells in photographs. Moreover, it is highly accurate, failing to detect only c. 1.4% of avian red cells in ordinary microscopic photographs. The Mizutama application may greatly facilitate the counting of erythrocytes and other blood cells in physiological studies, saving time and money. informacion[at]ebd.csic.es: Ochoa et al (2019) ...

Evaluation of Nuclear Morphometry and Ki-67 Index in Clear Cell Renal Cell Carcinomas: a Five-Year Study
Background and objective: Clear Cell Renal Cell Carcinoma (CCRCC) is the most common adult renal neoplasm. Staging and grading of RCC are important predictors of survival. Fuhrman nuclear grading is widely used for CCRCC, the subjective nature of which has prompted more objective methods to evaluate nuclear features. Furthermore, Ki-67, a reliable marker of cellular proliferation may provide another variable for assessment of the biological behavior of RCC. The aim of this research was to study nuclear morphometry and Fuhrman nuclear grading of clear cell RCC, and to assess their relationship with the Ki-67 index. Methods: Hematoxylin and eosin slides of forty cases of CCRCC were retrieved and studied for pathologic variables, including Fuhrman nuclear grade, pathological tumor and node stage. Nuclear morphometric analysis was performed using computer-assisted image analysis. The relationship between Fuhrman nuclear grading, pathologic stage, tumor size, nuclear morphometry and proliferative index were

Hormone Dependence in Premalignant Mammary Progression | Cancer Research
The p53-ull mammary epithelial model differs from the traditional mouse models of mammary tumorigenesis in several fundamental biological properties (5 , 6) . The traditional mouse models of mammary tumorigenesis, which are induced by mouse mammary tumor virus standard, arise from alveolar hyperplasias. These alveolar hyperplasias are negative for ER at the onset and generate ER-negative, hormone-independent tumors. In chemical carcinogen-treated mice, tumors arise from both alveolar hyperplasias and ductal hyperplasias. However, tumors are primarily hormone independent. Because the p53-null normal mammary epithelium and the serially transplanted, immortalized ductal outgrowths were ER positive, it was of interest to determine the hormonal dependency of preneoplastic progression in these cells.. The hormonal dependency of the p53-null normal mammary epithelium is indistinguishable from that of the p53 wild-type epithelium. Previous results demonstrated that growth and morphogenesis in ...
College of American Pathologists - December 2001 Anatomic Abstracts
Subjective assessment of flat urothelial lesions has often resulted in an under- or overdiagnosis of urothelial carcinoma in situ. To identify reproducible morphologic objective criteria, the authors used an image analysis system to measure several nuclear features (area, diameter, roundness, ellipticity, and optical density) in 20 cases each of CIS, urothelial dysplasia, and normal urothelium with adjacent lymphocyte controls. They did not analyze reactive urothelial lesions and umbrella cells. The most useful, statistically significant morphologic parameter was mean nuclear area of the largest 25 percent of nuclei. The mean upper quartile nuclear area relative to lymphocytes was 2.2 times (range, 1.4 to 2.8 times) in normal urothelium, 2.9 times (range, 1.8 to 3.6 times) in urothelial dysplasia, and 4.9 times (range, 4.0 to 7.6 times) in CIS. The nuclear size measurements for urothelial dysplasia and normal urothelium overlapped, but the separation between CIS and urothelial dysplasia was ...

Simultaneous use of cell-permeant and impermeant fluorescent nuclear dyes is a common method to study cell viability and cell death progression. Although these assays are usually conducted as end-point studies, time-lapse imaging offers a powerful technique to distinguish temporal changes in cell viability at single-cell resolution. SYTO 13 and Hoechst 33342 are two commonly used cell-permeant nuclear dyes; however their suitability for live imaging has not been well characterized. We compare end-point assays with time-lapse imaging studies over a 6 h period to evaluate the compatibility of these two dyes with longitudinal imaging, using both control neurons and an apoptotic neuron model. In longitudinal assays of untreated neurons, SYTO 13 addition caused acute necrosis within 3 h, whereas neurons imaged with Hoechst remained viable for at least 6 h. In a staurosporine-induced apoptotic model of neurotoxicity, determinations of the mode of cell death and measurements of nuclear size were identical
Genome size in turtle and crocodile | Biology Letters
TSC and CNI genome sizes based on the sum of chromosome sizes are close to GGA, but these sizes are smaller than those in the database . The larger genome sizes were obtained from the measurement of nuclear DNA content at cellular level. Both methods differ from DNA sequencing in that they require a DNA reference point from another species. When the reference species used for nuclear measurement is distantly related from the target species, the result may be influenced by varying fluorescence intensity owing to species variation in cell or nuclear sizes. In contrast to cells, chromosome structure shows little variation between species, and human chromosomes can be used as a reference for many species, even for zebrafish . Our measurement of 1.15 Gb for GGA is consistent with 1.05 Gb of the assembled sequence , showing that chromosome measurement has a high accuracy. Therefore, our method is to be preferred where whole-genome sequence is unavailable. Our data refine previous ...
Fast label-free multilayered histology-like imaging of human breast cancer by photoacoustic microscopy | Science Advances
Implementation of an intraoperative UV-PAM system for breast tumor excision could be transformative. Our UV-PAM system was able to image fixed, unprocessed breast tumors with an image quality comparable to that of conventional histology using processed, paraffin-embedded, sectioned, and H&E-stained specimens (Figs. 3 and 4 and fig. S4). Although fixed breast tumors were imaged in this study to maintain tissue integrity during relatively long intervals between surgery and processing for histology, fresh breast tumors are expected to provide similar imaging contrast (33). With relevant information regarding such tissue features as the average nuclear size and internuclear distance (Fig. 5), typically obtained from histology, UV-PAM images could be used to detect cancer cell clusters at the margins of tissue specimens during a surgical procedure, allowing immediate action to achieve clear margins. Although benign breast epithelial cells are too few in the UV-PAM images to be compared with cancer ...
CoCl2, a Mimic of Hypoxia, Induces Formation of Polyploid Giant Cells with Stem Characteristics in Colon Cancer
The induction of polyploidy is considered the reproductive end of cells, but there is evidence that polyploid giant cancer cells (PGCCs) contribute to cell repopulation during tumor relapse. However, the role of these cells in the development, progression and response to therapy in colon cancer remains undefined. Therefore, the main objective of this study was to investigate the generation of PGCCs in colon cancer cells and identify mechanisms of formation. Treatment of HCT-116 and Caco-2 colon cancer cells with the hypoxia mimic CoCl2 induced the formation of cells with larger cell and nuclear size (PGCCs), while the cells with normal morphology were selectively eliminated. Cytometric analysis showed that CoCl2 treatment induced G2 cell cycle arrest and the generation of a polyploid cell subpopulation with increased cellular DNA content. Polyploidy of hypoxia-induced PGCCs was confirmed by FISH analysis. Furthermore, CoCl2 treatment effectively induced the stabilization of HIF-1α, the differential

A contour property based approach to segment nuclei in cervical cytology images | SpringerLink
Segmentation of nuclei in cervical cytology pap smear images is a crucial stage in automated cervical cancer screening. The task itself is challenging due to the presence of cervical cells with spurious edges, overlapping cells, neutrophils, and artifacts. After the initial preprocessing steps of adaptive thresholding, in our approach, the image passes through a convolution filter to filter out some noise. Then, contours from the resultant image are filtered by their distinctive contour properties followed by a nucleus size recovery procedure based on contour average intensity value. We evaluate our method on a public (benchmark) dataset collected from ISBI and also a private real dataset. The results show that our algorithm outperforms other state-of-the-art methods in nucleus segmentation on the ISBI dataset with a precision of 0.978 and recall of 0.933. A promising precision of 0.770 and a formidable recall of 0.886 on the private real dataset indicate that our algorithm can effectively detect and
Enter the virus | Journal of Cell Biology | Rockefeller University Press
In the nuclear area, the proportion of microtubule-dependent, directed movement actually increases. Microtubules are not known to exist in interphase nuclei, so the authors suggest that the virus is travelling along invaginations in the nuclear envelope that have been observed by others. These invaginations may provide rapid access to the nuclear volume for both cellular materials and virus particles. Indeed, the speed of infection (with nuclear entry as an endpoint) is fast. Previous estimates of a two-hour infection were limited by the need to detect multiple virus particles. The new methods yield a figure of just 15 min.Bräuchle says the method can be used to track any virus, and might help gene therapists understand where their virus of choice is getting held up during the infection process. Meanwhile, he has made virus labeled on both capsid and DNA, so that he can track the exact location and kinetics of viral disassembly. ▪ ...

The first level consists of a deterministic procedure in which for each scenario the existence of at least one undamaged success path to comply with the fundamental safety function is investigated. This procedure can be subsequently extended to calculate probability measures such as conditional core damage probability and the conditional probability of spent fuel damage. In the most elaborated stage probabilistic safety assessment (PSA) techniques are introduced giving consideration to the probabilistic aspects of the hazards and of the capacity of structures systems and components (fragility). Event tree and fault tree models are used to compute PSA metrics such as core damage frequency large early release frequency and frequency of spent fuel ...
Parakeratosis - Wikipedia
Parakeratosis is a mode of keratinization characterized by the retention of nuclei in the stratum corneum. In mucous membranes, parakeratosis is normal. In the skin, this process leads to the abnormal replacement of annular squames with nucleated cells. Parakeratosis is associated with the thinning or loss of the granular layer and is usually seen in diseases of increased cell turnover, whether inflammatory or neoplastic. Parakeratosis is seen in the plaques of psoriasis and in dandruff. Granular parakeratosis (originally termed axillary granular parakeratosis) is an idiopathic, benign, nondisabling cutaneous disease that manifests with intertriginous erythematous, brown or red, scaly or keratotic papules and plaques. It presents in all age groups and has no established clinical associations.

ERC FUNDED PROJECTS | ERC: European Research Council
Summary A measurement of the 2S-2P transition frequencies (Lamb shift) in the muonic helium-3 and 4 ions by means of laser spectroscopy is proposed. This will lead to a ten times more accurate determination of the root-mean-square (rms) charge radii of the He-3 and He-4 nuclei. The radius of the magnetic moment distribution inside the He-3 nucleus will result from the hyperfine structure in muonic 3He. In the muonic helium ion, a single negative muon orbits the helium nucleus. The muon is a point-like lepton, just as the electron, except it is about 200 times heavier. This gives a factor of 200^3 = 10^7 enhancement of nuclear finite size effects on the energy levels of muonic vs. regular (electonic) Helium ions. Muonic helium is the ideal sytem to study the He nuclear size. The CREMA project has four main aims: (1) Solve the proton size puzzle created by our recently completed muonic hydrogen project [R. Pohl et al., The size of the proton, Nature 466, 213 (2010)]. Our tenfold ...
Dr. Daniel Gareau Ph.D. Biomedical Engineering - Automated identification of epidermal keratinocytes in reflectance confocal...
Abstract. Keratinocytes in skin epidermis, which have. bright cytoplasmic contrast and dark nuclear contrast in reflectance. confocal microscopy (RCM), were modeled with. a simple error function reflectance profile: erf( ). Fortytwo. example keratinocytes were identified as a training. set which characterized the nuclear size a = 8.6±2.8. μm and reflectance gradient b = 3.6±2.1 μm at the nuclear/. cytoplasmic boundary. These mean a and b parameters. were used to create a rotationally symmetric erf( ) mask. that approximated the mean keratinocyte image. A computer. vision algorithm used an erf( ) mask to scan RCM. images, identifying the coordinates of keratinocytes. Applying. the mask to the confocal data identified the positions. of keratinocytes in the epidermis. This simple model. may be used to noninvasively evaluate keratinocyte populations. as a quantitative morphometric diagnostic in skin. cancer detection and evaluation of dermatological cosmetics..

The resection rate is defined as the fraction of patients that proceed to planned surgery with removal of primary tumor (R0/R1) following neoadjuvant treatment with gemcitabine plus erlotinib.The resection rate will be estimated by the binomial point estimate, i.e. as the number of patients that undergo the planned surgery with removal of the primary tumor following neoadjuvant treatment with gemcitabine plus erlotinib divided by the number of evaluable patients. This quantity will also be estimated with a 95% binomial confidence interval..

Breast cancer often requires surgical treatment including breast-conserving surgical resection. However, with current post-surgical histological margin analysis, one-quarter of breast cancer patients undergo re-excision to achieve negative margins corresponding to decreased local recurrence and better outcomes. Therefore, a method with high resolution and specificity for intraoperative margin assessment is needed.
TNO Repository search for: subject:Mitosis index
Archival paraffin embedded material was used to examine whether additional quantitative criteria would be helpful to discriminate between histologically benign and malignant rat mammary tumours. To this end nuclear DNA content expressed as DNA ploidy index (DI) was measured using flow cytometry (FCM). A total of 63 benign and malignant mammary tumours were investigated. Thirteen out of 38 (34%) mammary carcinomas were DNA aneuploid against 0 out of 25 benign mammary tumours. Aneuploidy was not significantly increased in tumours showing histological signs of greater malignancy such as cribriform-comedo type or invasive growth. In addition to DI other quantitative criteria indicative for malignancy, such as mitotic count and nuclear morphometric characteristics, were estimated in 24 benign and malignant tubulopapillary tumours, a category where the histological classification may be difficult. It appeared that five out of nine noninvasive tubulopapillary carcinomas and six out of seven invasive ...

The Fractal Dimension as a Petrophysical Parameter.
The secondary electron emission from a Scanning Electron Microscope (SEM) was used to determine that the pore spaces of seven sandstones and four dolomites exhibited fractal behavior over certain length scales. Data from the SEM measurements produced log-log plots that not only verified the fractal nature of the rocks, but also allowed for the determination of their fractal dimensions. To model the transport properties of fractal lattices, a two dimensional model known as the Sierpinski Carpet was used as a starting point. Results developed for the petrophysical properties of such fractal lattices, such as porosity, permeability, capillary pressure, et. are presented here. Although the results cannot be directly compared with experiments, they demonstrate a methodology that can be applied to three dimensional lattices as well. A variation of a three dimensional fractal structure known as the Menger Sponge was used to model the pore spaces in rocks in an attempt to determine transport properties of rocks
