The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.Computer Systems: Systems composed of a computer or computers, peripheral equipment, such as disks, printers, and terminals, and telecommunications capabilities.Microscopy: The use of instrumentation and techniques for visualizing material and details that cannot be seen by the unaided eye. It is usually done by enlarging images, transmitted by light or electron beams, with optical or magnetic lenses that magnify the entire image field. With scanning microscopy, images are generated by collecting output from the specimen in a point-by-point fashion, on a magnified scale, as it is scanned by a narrow beam of light or electrons, a laser, a conductive probe, or a topographical probe.Microscopy, Electron, Scanning: Microscopy in which the object is examined directly by an electron beam scanning the specimen point-by-point. The image is constructed by detecting the products of specimen interactions that are projected above the plane of the sample, such as backscattered electrons. Although SCANNING TRANSMISSION ELECTRON MICROSCOPY also scans the specimen point by point with the electron beam, the image is constructed by detecting the electrons, or their interaction products that are transmitted through the sample plane, so that is a form of TRANSMISSION ELECTRON MICROSCOPY.Internet: A loose confederation of computer communication networks around the world. The networks that make up the Internet are connected through several backbone networks. The Internet grew out of the US Government ARPAnet project and was designed to facilitate information exchange.Gene Library: A large collection of DNA fragments cloned (CLONING, MOLECULAR) from a given organism, tissue, organ, or cell type. It may contain complete genomic sequences (GENOMIC LIBRARY) or complementary DNA sequences, the latter being formed from messenger RNA and lacking intron sequences.United StatesMicroscopy, Confocal: A light microscopic technique in which only a small spot is illuminated and observed at a time. An image is constructed through point-by-point scanning of the field in this manner. Light sources may be conventional or laser, and fluorescence or transmitted observations are possible.Databases, Factual: Extensive collections, reputedly complete, of facts and data garnered from material of a specialized subject area and made available for analysis and application.

Some must be administered before the event, but others may be effective for some time after. They act by a variety of mechanisms, but often directly or indirectly minimize the damage produced by endogenous excitatory amino acids.Neurons: The basic cellular units of nervous tissue. Each neuron consists of a body, an axon, and dendrites.

Cells, either as unicellular organisms or as part of a tissue of a multicellular organism, can acquire different functions thanks to their capability of changing their expression state. The enzyme synthesis, cell division or cell differentiation are some examples of these functions. The turning on and off of them lie in the mechanisms by which cells are able to integrate the information they perceive from the environment. Frequently, cells exhibit different responses under the same stimulus or environment. These probabilistic processes, whose behaviours are not univocal, are known as "cellular decision making". We can classify these processes according to the range at which the decision is made. We denominate cell-autonomous decision those in which of each cell chooses its response independently of the choice of the other cells of the population. By contrast, if the decision is made collectively by the whole population, it is classified as non autonomous. This second type of decisions involve ...
Many cellular processes require decision making mechanisms, which must act reliably even in the unavoidable presence of substantial amounts of noise. However, the multistable genetic switches that underlie most decision-making processes are dominated by fluctuations that can induce random jumps between alternative cellular states. Here we show, via theoretical modeling of a population of noise-driven bistable genetic switches, that reliable timing of decision-making processes can be accomplished for large enough population sizes, as long as cells are globally coupled by chemical means. In the light of these results, we conjecture that cell proliferation, in the presence of cell-cell communication, could provide a mechanism for reliable decision making in the presence of noise, by triggering cellular transitions only when the whole cell population reaches a certain size. In other words, the summation performed by the cell population would average out the noise and reduce its detrimental impact ...
Objective: We investigated the association of anti-inflammatory cytokines interleukin-1 receptor antagonist (IL-1ra) and adiponectin as well as pro-inflammatory cytokines IL-1β, IL-6, CCL2 and tumor necrosis factor (TNF)-α with β-cell function, metabolic status and clinical remission in patients with recent onset type 1 diabetes.. Research Design and Methods: Serum was obtained from 256 newly diagnosed patients (122 males/134 females, median age 9.6 years). Stimulated C-peptide, blood glucose and HbA1c were determined in addition to circulating concentration of cytokines at one, six and twelve months after diagnosis. Analyses were adjusted for sex, age and BMI percentiles.. Results: Anti-inflammatory IL-1ra was positively associated with C-peptide after six (p=0.0009) and twelve months (p=0.009). The beneficial association of IL-1ra on β-cell function was complemented by the negative association of IL-1β with C-peptide after one month (p=0.009). In contrast, anti-inflammatory adiponectin ...
The folding state of polypeptides is easily perturbed by adverse conditions. Misfolded proteins are non-functional and lead to a measure of inefficiency in the cells economy. Their presence has additional consequences that are unrelated to loss-of-function features as numerous genetic and biochemical observations suggest that structures elaborated by polypeptides that fail to attain their proper three dimensional structure have deleterious gain-of-function effects on cell function. This process, also referred to as proteotoxicity, appears to be particularly important to the fate of non-renewable cells of long-lived organisms in which accumulating misfolded proteins can act over extended periods of time. The hypothesized contribution of such proteotoxins to cellular dysfunction fits our intuitive notions of aging as a time and use-dependent process. The progressive aging of the human population has led to an increase in the incidence of diseases hypothesized to be associated with various ...

We have shown that near-total α-cell loss in adult mice has little effect on glucagonemia and no apparent effect on β-cell function or glucose homeostasis. This reveals that 2 to 4% of the normal α-cell mass is astonishingly sufficient to produce enough glucagon to ensure glycemic control under basal conditions. Massive α-cell loss is associated with a rapid enhancement of glucagon sensitivity, which allows increased glucose mobilization, even if the decrease in glucagonemia is very mild.. A corollary of this observation is that the normal amount of pancreatic α-cells apparently exceeds the physiologic requirement for proper blood glucose homeostasis. Indeed, the total glucagon found in the pancreas when only 2% of the α-cells remain was sufficient to maintain normoglucagonemia. A simple calculation reveals that if all pancreatic glucagon found 1 week after α-cell loss (∼7,400 pg; Supplementary Table 2) were entirely released at once into the circulation, glucagonemia would be more than ...

As indicated above, renin cells communicate with one another and with adjacent cells, including smooth muscle, mesangial cells, and perivascular interstitial cells. Disruption of such communication alters the renin phenotype, demonstrating that the identity of these cells is heavily dependent on the cells context, particularly their interaction with other cell types.. The Notch pathway is an ancestral, highly conserved, cell-to-cell communication system involved in cell fate decisions during development and in response to physiological challenges.54,55 Notch receptors, their ligands, and their final transcriptional effector, RBP-J, are expressed in renin cells.32 We found that the disruption of the Notch pathway either by the inhibition of γ-secretase (unpublished) or conditional deletion of RBP-J in renin cells56 results in severe reduction in the number of renin cells, low circulating renin, and decreased blood pressure. Further, mutant mice are unable to recruit renin cells in response to a ...

Genetics is a powerful tool, especially when used in combination with embryology, in the seeking of genes necessary for assembly of the cardiovasculature. The first questions must address the types of cellular decisions that are made during development. As for simpler systems in C elegans and D melanogaster, the lineage and cell-fate decisions of the cardiovascular progenitors need to be assessed. In addition it is likely that new paradigms will emerge for multicellular assembly. The study of cardiovascular mutations will define individual genetic steps that define organotypic decisions. A genetic approach is a natural extension of embryology, physiology, and anatomy, fields of great sophistication with regard to the cardiovasculature, because, like them, it focuses on integrative biology and on the intact organism. The zebrafish is particularly well suited to a combination genetic-embryologic study of the fashioning of the cardiovasculature. ...

My research interests include Bacterial Cell Cycle Regulation and Signal Transduction mechanisms.. 1. Bacterial Cell Cycle Regulation- Epigenetic mechanisms regulating various physiological activities in the prokaryotic cells are increasingly being appreciated. Methylation of specific bases of the DNA molecule by methyltransferases is the most common epigenetic modification observed in the bacterial cells. This modification of nucleotides adds another level of regulation at the transcription; furthermore, it has a fundamental role in the cell physiological processes such as DNA replication, DNA mismatch repair, and virulence mechanisms in many pathogens. Among the prokaryotic DNA methyltransferases, Dam expressed among the Gammaproteobacteria is the most intensively studied. In contrast to Dam, another DNA methyltransferase CcrM (Cell Cycle Regulated Methylase) has been described in the Alphaproteobacteria, where it plays an important role in the cell cycle regulation of Caulobacter crescentus ...
Mitochondrial DNA haplogroups and ageing mechanisms in osteoarthritis | Annals of the Rheumatic Diseases
From previous studies, it is known that the low OA risk haplogroup J is associated with lower serum levels of markers of collagen type-II degradation and of matrix metalloproteinases, but all of these studies failed to address the key question arising from this large body of evidence: What is the functional role of these mtDNA haplogroups?. To answer this question, Fernandez-Moreno et al7 used cytoplasmic hybrid (cybrid) cell lines. Cybrids incorporate mitochondria from human subjects and perpetuate the mtDNA-encoded components while maintaining the nuclear background of different cybrid lines as constant.16 Thus, this technique allows investigators to assess the influence of mtDNA variation on cell function. To investigate the role of mtDNA haplogroups, they also created cybrids using osteosarcoma cell lines with the same nuclear background, one of them harbouring the haplogroup J (which protects against OA) and another harbouring the haplogroup H (linked to higher risk of OA).. The cybrids ...
Sigma Zeta 2014 Fall Banquet:. On Tuesday, November 4th our own Dr. Nathan Lindquist from the physics department spoke on "Interdisciplinary nanotechnology research: the science and its many applications." Over the past few years, Bethel has invested in building a "NanoLab" for interdisciplinary student/faculty research on microscopy, spectroscopy, imaging, bio-sensing, nano-fabrication and nano-characterization. The recent addition of a Scanning Electron Microscope further builds our potential for cutting-edge projects. The talk provided some background on the science of nanotechnology, the tools of the trade, and its many promising applications. We found out how nano-research is directly aimed at solving some of our biggest challenges in energy, healthcare, and the environment. As is our custom in the fall, our banquet is a combined event with members of the Minnesota Microscopy Society. We had a total of 48 in attendance including students, faculty and MMS members. We recognized new members ...
Cellular decisions to live or die are fundamental to development and adult homeostasis, playing roles in a wide variety of physiological and pathological processes. These include cancer, degenerative disease, innate and adaptive immunity, ischemia-reperfusion injury, and infectious disease. As the study of cell death moves beyond the central mechanisms of apoptosis to wider issues of regulation and other forms of cell death, this vibrant area of research widens its influence and importance for human health and disease.
Pancreatic cancer begins in pancreas tissues. Pancreas lies in the abdomen just behind the lower part of the stomach. These secrete enzymes which help in digestion and hormones which help in regulating sugar metabolism. Often, pancreatic cancer has a poor prognosis even it is diagnosed early. Typically, it spreads rapidly. It is rarely detected in the initial stage. This is the major reason for many pancreatic cancer deaths. Symptoms do not develop till the cancer reaches advanced stage and it is not possible to remove it surgically. Pancreatic Cancer Causes: ...
The Food and Drug Administration is looking into new evidence that suggests a group of recently approved diabetes drugs can increase the risk of pancreatitis and other problems. The agency said Thursday samples of pancreas tissue taken from a small number of patients showed inflammation and cellular changes that often precede cancer. Academic researchers took the samples from diabetes patients who were taking the new medications, after they died from various causes.
Molecules | Free Full-Text | Promising Low-Toxicity of Viologen-Phosphorus Dendrimers against Embryonic Mouse Hippocampal Cells
A new class of viologen-phosphorus dendrimers (VPDs) has been recently shown to possess the ability to inhibit neurodegenerative processes in vitro. Nevertheless, in the Central Nervous Systems domain, there is little information on their impact on cell functions, especially on neuronal cells. In this work, we examined the influence of two VPD (VPD1 and VPD3) of zero generation (G0) on murine hippocampal cell line (named mHippoE-18). Extended analyses of cell responses to these nanomolecules comprised cytotoxicity test, reactive oxygen species (ROS) generation studies, mitochondrial membrane potential (ΔΨm) assay, cell death detection, cell morphology assessment, cell cycle studies, as well as measurements of catalase (CAT) activity and glutathione (GSH) level. The results indicate that VPD1 is more toxic than VPD3. However, these two tested dendrimers did not cause a strong cellular response, and induced a low level of apoptosis. Interestingly, VPD1 and VPD3 treatment led to a small decline in ROS

Modeling of phenomena observed in biological systems and the search for underlying mechanisms and principles have a long history, with remarkable contributions from Mathematical Biology. The development of the Hodgkin-Huxley model as an explanation of the temporal behavior of excited neurons or the class of predator-prey models for describing the dynamics of competing populations are prominent examples. Their principles can still be found in many areas of research (see e.g. Chapter 2 in  or Chapter 3 in ). Moreover, although classical Cell Biology was in the past a predominantly reductionist approach, in which cells were broken down into small subsystems, this was always accompanied by models on the system level. Regulation processes that drive cellular decisions, such as the lytic and lysogenic pathway in bacteriophage lambda [5, 6], the diauxic switch between glucose and lactose uptake in bacterial cells  or apoptotic decision processes , have been in the focus of interest for a ...
In the 1860s, the German scientist Paul Langerhans discovered tiny patches of cells in cross-sections of pancreas tissues. They looked like little islands, hence their name - islets of Langerhans. These islets have a rich blood supply and consist of two type of cells - larger alpha cells and numerous smaller beta cells. The function of these islets were unknown until the 20th century when scientists found that removing the pancreas for an animal resulted in a disease similar to human diabetes (incidentally, dogs and cats can get diabetes too).. It was isolated in the 1920s by Banting, Best & MacLeod in Canada.. Animals with their pancreas removed were treated with the "insulin" (meaning island), and this cured the animals of the diabetes. Animal insulin was then successfully used to treat humans for many years before genetic engineering took over the production.. ...
Each cell division, the nuclear DNA must be replicated efficiently and with high accuracy to avoid mutations which can have an effect on cell function. There are three replicative DNA polymerases essential for the synthesis of DNA during replication in eukaryotic cells. DNA polymerase α (Pol α) synthesize short primers required for DNA polymerase δ (Pol δ) and DNA polymerase ε (Pol ε) to carry out the bulk synthesis. The role of Pol δ and Pol ε at the replication fork has been unclear. The aim of this thesis was to examine what role Pol ε has at the replication fork, compare the biochemical properties of Pol δ and Pol ε, and to study the function of the second largest and essential subunit of Pol ε, Dpb2.. To identify where Pol ε replicates DNA in vivo, a strategy was taken where the active site of Pol ε was altered to create a mutator polymerase leaving a unique error-signature. A series of mutant pol ε proteins were purified and analyzed for enzyme activity and fidelity of DNA ...

Defective insulin secretion by chronic glucagon receptor activation in glucose intolerant mice in: Journal of Endocrinology...
Hyperglucagonemia is an important factor for type 2 diabetes which contributes to increased hepatic glucose production (Rizza 2010). In spite of this, however, little is known about the role of chronically elevated glucagon levels for β-cell function. A reason for this is the lack of appropriate models of long-term glucagon action, which in part is due to difficulties in administering native glucagon long-term because of poor chemical and physical stability. Therefore, in the current study, we administered a stable glucagon analog (ZP-GA-1) to mice fed a HFD to create a novel model for studying effects of chronic GCGR activation on β-cell function. The HFD fed mice do not develop hyperglucagonemia (Ahlkvist et al. 2013) which allowed us to study the impact of chronic GCGR stimulation on glucose tolerance in a glucose intolerant model without the confounding factor of endogenous hyperglucagonemia. In these mice, 2-week ZP-GA-1 infusion markedly reduced the insulin response to oral glucose. ...

As a result, Dr. Waldman notes, the findings also indicate that these miRNAs can serve as diagnostic markers. "Because they are involved in processes underlying cancer, these specific miRNAs mediate the disease process in different types of cells, such as pancreas or lung, for example," he says. "There apparently is a profile of miRNAs that identify pancreatic cancer cells from other types. It appears that in some cases, there are common miRNAs, and for others there are miRNAs that can distinguish different types of cancer. A tumor can be profiled based on miRNAs." MiRNAs cans serve as prognostic markers as well. "They apparently distinguish normal pancreas tissue from inflamed tissue from cancer, and this paper shows miRNAs correlate with who will do well and who wont," Dr. Waldman explains. "Presumably, it follows that miRNAs could be predictive markers, which could have implications for therapy. "On top of this, there is a new layer of biology that is identifying novel mechanisms involved in ...
Background : Carcinoma of the pancreas is a fatal malignant disease with limited therapeutic options. Cyclooxygenase-2 (COX-2) and c-erbB-2 are known to be involved in the carcinogenesis, differentiation and invasiveness of various neoplasms. We studied the immunohistochemical expressions of c-erbB-2 and COX-2 and the correlation between these expressions and the clinicopathologic parameters and the relation between the expressions. Methods : Immunohistochemical staining for c-erbB-2 and COX-2 were performed on the paraffin embedded sections of 36 cases of surgically resected ductal adenocarcinoma of the pancreas and 10 cases of non-neoplastic pancreas tissue. Results : The non-neoplastic control group showed a c-erbB-2 expression in the acini (8/10) and ducts (2/10), and a COX-2 expression in the acini (6/10) and ducts (3/10). The overexpression of c-erbB-2 was observed in 58% (21/36) of the carcinoma specimens. No significant correlation was found between c-erbB-2 and age, gender, tumor size, ...

Nectins and Nectin-like molecules (Necl) are families of cellular adhesion molecules involved in Ca2+-independent cellular adhesion. Nectins are ubiquitously expressed and have adhesive roles in a wide range of tissues such as the adherens junction of epithelia or the chemical synapse of the neuronal tissue. So far four nectins have been identified in humans, namely nectin-1, nectin-2, nectin-3 and nectin-4. These four family members have also been found in most other well studied mammals. Also, five Necls have been identified, these are: Necl-1, Necl-2, Necl-3, Necl-4 and Necl-5. All nectins and all Necls share the same overall structure defined by three extra cellular immunoglobulin domains, a single transmembrane helix and an intracellular domain. For all nectins the intracellular domain can bind a scaffold protein named afadin (the product of the MLLT4 gene). All nectins and Necls can form homo-cis dimers, meaning a dimer of two alike molecules on the same cell membrane. Following the ...
