Acidosis caused by accumulation of lactic acid more rapidly than it can be metabolized. It may occur spontaneously or in association with diseases such as DIABETES MELLITUS; LEUKEMIA; or LIVER FAILURE.
A mitochondrial disorder characterized by focal or generalized seizures, episodes of transient or persistent neurologic dysfunction resembling strokes, and ragged-red fibers on muscle biopsy. Affected individuals tend to be normal at birth through early childhood, then experience growth failure, episodic vomiting, and recurrent cerebral insults resulting in visual loss and hemiparesis. The cortical lesions tend to occur in the parietal and occipital lobes and are not associated with vascular occlusion. VASCULAR HEADACHE is frequently associated and the disorder tends to be familial. (From Joynt, Clinical Neurology, 1992, Ch56, p117)
A group of muscle diseases associated with abnormal mitochondria function.
A transfer RNA which is specific for carrying leucine to sites on the ribosomes in preparation for protein synthesis.
A heterogenous group of disorders characterized by alterations of mitochondrial metabolism that result in muscle and nervous system dysfunction. These are often multisystemic and vary considerably in age at onset (usually in the first or second decade of life), distribution of affected muscles, severity, and course.

Proteins that bind specific drugs with high affinity and trigger intracellular changes influencing the behavior of cells. Drug receptors are generally thought to be receptors for some endogenous substance not otherwise specified.
A molecule that binds to another molecule, used especially to refer to a small molecule that binds specifically to a larger molecule, e.g., an antigen binding to an antibody, a hormone or neurotransmitter binding to a receptor, or a substrate or allosteric effector binding to an enzyme. Ligands are also molecules that donate or accept a pair of electrons to form a coordinate covalent bond with the central metal atom of a coordination complex. (From Dorland, 27th ed)
Molecules on the surface of T-lymphocytes that recognize and combine with antigens. The receptors are non-covalently associated with a complex of several polypeptides collectively called CD3 antigens (ANTIGENS, CD3). Recognition of foreign antigen and the major histocompatibility complex is accomplished by a single heterodimeric antigen-receptor structure, composed of either alpha-beta (RECEPTORS, ANTIGEN, T-CELL, ALPHA-BETA) or gamma-delta (RECEPTORS, ANTIGEN, T-CELL, GAMMA-DELTA) chains.
The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

WW: An isolated three-stranded antiparallel beta-sheet domain that unfolds and refolds reversibly; evidence for a structured hydrophobic cluster in urea and GdnHCl and a disordered thermal unfolded state. (1/338)

The objective of this study was to evaluate the suitability of the WW domain as a desirable model system to understand the folding and stability of an isolated three-stranded antiparallel beta-sheet structure. The WW domain was subjected to thermal and chaotropic denaturation/reconstitution utilizing a variety of biophysical methods. This three-stranded sheet folds reversibly and cooperatively utilizing both urea and GdnHCl as denaturants; however, the denatured state retains structure in the form of a hydrophobic cluster involving at least one aromatic side chain. In contrast to chaotropic denaturation, thermal denaturation appears to be more complete and may be a two state process. The suitability of the WW domain for future studies aimed at understanding the kinetics and thermodynamics of antiparallel beta-sheet folding clearly emerges from this initial study. The most exciting and significant result in this manuscript is the finding that the chaotropic denatured state of WW has a hydrophobic cluster as discerned by near-UV CD evidence. The role that the denatured state plays in the folding and stability of a three-stranded beta-sheets, and its capacity for preventing aggregation may be particularly important and is the subject of ongoing studies.  (+info)

Detection of putative Zn(II) binding sites within Escherichia coli RNA polymerase: inconsistency between sequence-based prediction and 65Zn blotting. (2/338)

The availability of repeating 'Cys' and/or 'His' units in a particular order prompts the prediction of Zn(II) finger motifs in a protein. Escherichia coli RNA polymerase has two tightly bound Zn(II) per molecule of the enzyme as detected by atomic absorption spectroscopy. One Zn(II) was identified to be at the beta subunit, whereas the other putative Zn(II) binding site has recently been predicted to be at the N-terminal half of the beta' subunit, from primary sequence analysis. We show here that the beta' subunit has no ability to bind 65Zn(II). On the other hand, the N-terminal domain of the alpha subunit has strong Zn(II) binding ability with no obvious functional implications.  (+info)

Thiopental attenuates hypoxic changes of electrophysiology, biochemistry, and morphology in rat hippocampal slice CA1 pyramidal cells. (3/338)

BACKGROUND AND PURPOSE: Thiopental has been shown to protect against cerebral ischemic damage; however, it has undesirable side effects. We have examined how thiopental alters histological, physiological, and biochemical changes during and after hypoxia. These experiments should enable the discovery of agents that share some of the beneficial effects of thiopental. METHODS: We made intracellular recordings and measured ATP, sodium, potassium, and calcium concentrations from CA1 pyramidal cells in rat hippocampal slices subjected to 10 minutes of hypoxia with and without 600 micromol/L thiopental. RESULTS: Thiopental delayed the time until complete depolarization (21+/-3 versus 11+/-2 minutes for treated versus untreated slices, respectively) and attenuated the level of depolarization at 10 minutes of hypoxia (-33+/-6 versus -12+/-5 mV). There was improved recovery of the resting potential after 10 minutes of hypoxia in slices treated with thiopental (89% versus 31% recovery). Thiopental attenuated the changes in sodium (140% versus 193% of prehypoxic concentration), potassium (62% versus 46%), and calcium (111% versus 197%) during 10 minutes of hypoxia. There was only a small effect on ATP (18% versus 8%). The percentage of cells showing clear histological damage was decreased by thiopental (45% versus 71%), and thiopental improved protein synthesis after hypoxia (75% versus 20%). CONCLUSIONS: Thiopental attenuates neuronal depolarization, an increase in cellular sodium and calcium concentrations, and a decrease in cellular potassium and ATP concentrations during hypoxia. These effects may explain the reduced histological, protein synthetic, and electrophysiological damage to CA1 pyramidal cells after hypoxia with thiopental.  (+info)

Mitotic misregulation and human aging. (4/338)

Messenger RNA levels were measured in actively dividing fibroblasts isolated from young, middle-age, and old-age humans and humans with progeria, a rare genetic disorder characterized by accelerated aging. Genes whose expression is associated with age-related phenotypes and diseases were identified. The data also suggest that an underlying mechanism of the aging process involves increasing errors in the mitotic machinery of dividing cells in the postreproductive stage of life. We propose that this dysfunction leads to chromosomal pathologies that result in misregulation of genes involved in the aging process.  (+info)

Oestrogen, progesterone, and androgen receptors in ovarian neoplasia: correlation between immunohistochemical and biochemical receptor analyses. (5/338)

AIM: To investigate the correlation between immunohistochemical and biochemical steroid receptor analyses by measurement of oestrogen, progesterone, and androgen receptor status in ovarian neoplasia. METHODS: Tissue samples were obtained from 27 ovarian neoplasms, including two borderline tumours. Immunohistochemical staining of the tissue slides was scored semiquantitatively, incorporating the intensity and percentage of positive staining (histo-score). Tumours with a histo-score of 10 or more were considered steroid receptor positive. The epithelial and stromal fractions of the tumours were analysed separately. To study the uniformity of receptor expression throughout a tumour, up to four samples were analysed. RESULTS: Immunohistochemical histo-scores of the oestrogen receptor in the epithelial fractions were significantly correlated with the biochemical oestrogen receptor values (r = 0.408). Androgen receptor status in the epithelial fraction was correlated with that in the stromal fraction (r = 0.741), while androgen receptor histo-scores in the epithelial fraction correlated with the biochemical assay values (r = 0.463). On biochemical analysis, 17 of the 27 ovarian tumours were oestrogen receptor positive and seven were progesterone receptor positive. On immunohistochemical analysis, eight tumours were oestrogen receptor positive and two were progesterone receptor positive. Biochemical analysis showed that 14 of the 26 tumours were slightly androgen receptor positive (10-50 fmol/mg protein), while all the others were negative. On immunohistochemical analysis, seven of the 26 tumours were androgen receptor positive. When two or more specimens from one tumour were analysed, marked differences in steroid status were found, especially in progesterone receptor and androgen receptor expression. Some parts of a tumour were steroid receptor positive, while other parts were negative owing to heterogeneity of expression. CONCLUSIONS: Immunohistochemical and biochemical analysis of steroid receptors in ovarian tumours correlated weakly or not at all. Heterogeneity of expression within a tumour and the presence of progesterone and androgen receptors in the stromal fraction partly accounted for this observation. Biochemical and immunohistochemical androgen receptor status was much lower than in previous reports.  (+info)

Trehalose effect on low temperature protein dynamics: fluctuation and relaxation phenomena. (6/338)

We performed spectral diffusion experiments in trehalose-enriched glycerol/buffer-glass on horseradish peroxidase where the heme was replaced by metal-free mesoporphyrin IX, and compared them with the respective behavior in a pure glycerol/buffer-glass (Schlichter et al., J. Chem. Phys. 2000, 112:3045-3050). Trehalose has a significant influence: spectral diffusion broadening speeds up compared to the trehalose-free glass. This speeding up is attributed to a shortening of the correlation time of the frequency fluctuations most probably by preventing water molecules from leaving the protein interior. Superimposed to the frequency fluctuation dynamics is a relaxation dynamics that manifests itself as an aging process in the spectral diffusion broadening. Although the trehalose environment speeds up the fluctuations, it does not have any influence on the relaxation. Both relaxation and fluctuations are governed by power laws in time. The respective exponents do not seem to change with the protein environment. From the spectral dynamics, the mean square displacement in conformation space can be determined. It is governed by anomalous diffusion. The associated frequency correlation time is incredibly long, demonstrating that proteins at low temperatures are truly nonergodic systems.  (+info)

A new method for mapping nucleic acid sequence homology by electron microscopy. (7/338)

We describe here a new method for the electron microscopic mapping of sequence homology in nucleic acids. Specific segments of the T7 chromosome have been isolated following digestion with the restriction endonuclease from Hemophilus aegyptious (Haey). Denatured segments are annealed to the l-strand of T7 DNA; treatment of the hybrid with glyoxal allows only guanosine residues in the single-chain region to the reacted, producing an adduct which will no longer hydrogen bond with its complement on the r-strand. When the segment is displaced and the glyoxalated l-strand allowed to renature with the r-strand, "H" shaped structures are produced in which the duplex region corresponds to the position of sequence homology with the segment. The conditions employed for glyoxalation do not detectably disrupt duplex regions as small as 400 base pairs. This procedure should be generally useful for observing sequence homology in more complex DNA molecules containing duplex regions which can be specifically enriched for and their arrangement determined by electron microscopy.  (+info)

A novel method to determine the topology of peroxisomal membrane proteins in vivo using the tobacco etch virus protease. (8/338)

Most proteins essential for the biogenesis of peroxisomes (peroxins) that are identified to date are associated with or are integral components of the peroxisomal membrane. A prerequisite in elucidating their function is to determine their topology in the membrane. We have developed a novel tool to analyze the topology of peroxisomal membrane proteins in the yeast Hansenula polymorpha in vivo using the 27-kDa NIa protease subunit from the tobacco etch virus (TEVp). TEVp specifically cleaves peptides containing the consensus sequence, EXXYXQ downward arrowS (tev). We show that cytosolic TEVp and peroxisomal TEVp.SKL are selectively active on soluble cytosolic and peroxisomal tev-containing proteins in vivo, respectively, without affecting the viability of the yeast cells. The tev sequence was introduced in between the primary sequence of the peroxisomal membrane proteins Pex3p or Pex10p and the reporter protein enhanced green fluorescent protein (eGFP). Co-synthesis of these functional tev-GFP tagged proteins with either cytosolic TEVp or peroxisomal TEVp.SKL revealed that the C termini of Pex3p and Pex10p are exposed to the cytosol. Additional applications of the TEV protease to study peroxisome biogenesis are discussed.  (+info)

Westminster-based Myogen Inc.s shares soared Monday after its experimental drug helped patients with a potentially fatal lung disorder in a pivotal trial. A study, one of two needed for U.S. regulatory approval, found that the drug ambrisentan improved patients breathing and slowed worsening of pulmonary arterial hypertension, Myogen said. The once-a-day pill eased shortness of breath, allowing patients to walk farther in a six-minute test, the firm said. Geoffrey Meacham, an analyst at J.P. Morgan Securities Inc., said the results were better than he expected. The findings clearly position ambrisentan to become a best- in-class oral pulmonary arterial hypertension agent, Meacham wrote in a note to clients. Myogen remains, in our view, one of the most attractive pipeline stories in biotech, with ambrisentan and the darusentan drug for high blood pressure in development, he said. In the condition that ambrisentan is intended to treat, the pulmonary arteries thicken and become severely ...

The forward reaction above is of the pseudo first order, as the professor says. But its rate constant depends on acidic catalytic factors and the net reaction rate is affected by the reverse reaction rate The concentration of products- the organic acid and the alcohol - affects the net reaction rate by increased rate of the reverse reaction and by shifting of the reaction quotient.. The content of a mineral acid catalyzes the reaction, what means speeding up both reactions, therefore keeping the same equilibrium constant.(required as consequence of the energy conservation law). The reaction is still the pseudo first order, but the rate constant depends on concentration of the catalysing acid.. The alternative approach is considering the mineral acid as self-regenerating reagent. But it must be then evaluated as reaction chain.. The content of a mineral base decreases reverse reaction rate and shifts the reaction quotient by reacting with the organic acid. It also directly reacts with the ...
A method for maintaining the attitude of a three-axis controlled satellite by use of magnetic torquers includes using magnetometers for measuring the direction of the ambient geomagnetic field. The direction of the net reaction wheel momentum is also determined. The angle between the direction of the geomagnetic field and the net reaction wheel momentum is determined. The angle is compared with a threshold value. Magnetic torquer power consumption is reduced by operating the magnetic torquers only when the angle exceeds the threshold value.

Artur Meski, Maciej Koutny, Wojciech Penczek: Verification of Linear-Time Temporal Properties for Reaction Systems with Discrete Concentrations. Fundam. Inform. 154(1-4): 289-306 (2017). Abstract. Reaction systems are a formal model for computational processes inspired by the functioning of the living cell. This paper introduces reaction systems with discrete concentrations, which are an extension of reaction systems allowing for quantitative modelling. We demonstrate that although reaction systems with discrete concentrations are semantically equivalent to the original qualitative reaction systems, they provide much more succinct representations in terms of the number of entities being used. We define a variant of Linear Time Temporal Logic interpreted over models of reaction systems with discrete concentrations. We provide its suitable encoding in SMT, together with bounded model checking, and present experimental results demonstrating the scalability of the verification method for reaction ...

State-of-the-art biochemical systems for medical applications and chemical computing are application-specific and cannot be re-programmed or trained once fabricated. The implementation of adaptive biochemical systems that would offer flexibility through programmability and autonomous adaptation faces major challenges because of the large number of required chemical species as well as the timing-sensitive feedback loops required for learning. Currently, biochemistry lacks a systems vision on how the user-level programming interface and abstraction with a subsequent translation to chemistry should look like. By developing adaptation in chemistry, we could replace multiple hard-wired systems with a single programmable template that can be (re)trained to match a ...

The common names of ligases often include the word ligase, such as DNA ligase, an enzyme commonly used in molecular biology laboratories to join together DNA fragments. Other common names for ligases include the word synthetase, because they are used to synthesize new molecules. Biochemical nomenclature has sometimes distinguished synthetases from synthases and sometimes treated the words as synonyms. Under one definition, synthases do not use energy from nucleoside triphosphates (such as ATP, GTP, CTP, TTP, and UTP), whereas synthetases do use nucleoside triphosphates. It is also said that a synthase is a lyase (a lyase is an enzyme that catalyzes the breaking of various chemical bonds by means other than hydrolysis and oxidation, often forming a new double bond or a new ring structure) and does not require any energy, whereas a synthetase is a ligase (a ligase is an enzyme that binds two chemicals or compounds) and thus requires energy.

BSc Medical Biochemistry/MSci Clinical Biochemistry at Middlesex University explores the field of biochemistry with a focus on human biology and medicine.
Biochemistry instructors are inundated with various representations from which to choose to depict biochemical phenomena. Because of the immense amount of visual know-how needed to be an expert biochemist in the 21st century, there have been calls for instructors to develop biochemistry students' visual literacy. However, visual literacy has multiple aspects, and determining which area to develop can be quite daunting. Therefore, the goals of this study were to determine what visual literacy skills biochemistry instructors deem to be most important and how instructors develop and assess visual literacy skills in their biochemistry courses. In order to address these goals, a needs assessment was administered to a national sample of biochemistry faculty at four-year colleges and universities. Based on the results of the survey, a cluster analysis was conducted to group instructors into categories based on how they intended to develop visual literacy in their courses. A

Analytical toxicology is concerned with the role of the laboratory in the diagnosis, treatment and prevention of poisoning. Analytical toxicologists spend much of their time measuring compounds such as alcohols, drugs and poisons in biological samples and in providing an interpretation of any results generated.. Most Clinical Biochemistry laboratories within the NHS will perform a degree of analytical toxicology as part of their routine workload, usually for patients who present to the emergency department having knowingly or accidentally ingested a poison. Most analysis performed in these circumstances is done by automated analysers and requires a fast turnaround time. Commonly encountered compounds include ethanol, paracetamol, salicylate and lithium. Clinical Scientists who work within this setting may be required to oversee the performance of the assays as well as provide interpretative advice on the results generated.. There are a number of more specialised analytical toxicology ...

Publisher: University of Delaware. Date Issued: 2018. Abstract: At the level of individual living cells, key species such as genes, mRNAs, and proteins are typically present in small numbers. Consequently, the biochemical reactions involving these species are inherently noisy and result in considerable cell-to-cell variability. This thesis outlines two mathematical tools to quantify stochasticity in these biochemical reaction systems: (i) a novel computational method that provides exact lower and upper bounds on statistical moments of population counts of important species, and (ii) a first-passage time framework to study noise in the timing of a cellular event that occurs when population count of an underlying regulatory protein attains a critical threshold. ☐ The method to compute bounds on moments builds upon the well-known linear dynamical system that describes the time evolution of statistical moments. However, except for some ideal cases, this dynamical system is not closed in the sense ...
TY - JOUR. T1 - Dynamic biochemical reaction process analysis and pathway modification predictions. AU - CONEJEROS RISCO, RAUL JORGE. AU - Vassiliadis, Vassilios S.. PY - 2000/5/5. Y1 - 2000/5/5. N2 - Recently, the area of model predictive modification of biochemical pathways has received attention with the aim to increase the productivity of microbial systems. In this study, we present a generalization of previous work, where, using a sensitivity study over the fermentation as a dynamic system, the optimal selection of reaction steps for modification (amplification or attenuation) is determined. The influence of metabolites in the activity of enzymes has also been considered (through activation or inhibition). We further introduce a new concept in the dynamic modeling of biochemical reaction systems including a generalized continuous superstructure in which two artificial multiplicative terms are included to account for: (a) enzyme overexpression or underexpression (attenuation or ...

AU - Ejeh, D.. AU - Hambright, P.. AU - Fujita, Etsuko. PY - 1998/4/23. Y1 - 1998/4/23. N2 - Several cobalt porphyrins (CoP) have been reduced by radiation chemical, photochemical, and electrochemical methods, in aqueous and organic solvents. In aqueous solutions, the CoIP state is stable at high pH but is shorter lived in neutral and acidic solutions. Stable CoIP is also observed in organic solvents and is unreactive toward CO2. One-electron reduction of CoIP leads to formation of a species that is observed as a transient intermediate by pulse radiolysis in aqueous solutions and as a stable product following reduction by Na in tetrahydrofuran solutions. The spectrum of this species is not the characteristic spectrum of a metalloporphyrin π-radical anion and is ascribed to Co0P. This species binds ...

An artificial chemistry is a chemical-like system that usually consists of objects, called molecules, that interact according to rules resembling chemical reaction rules. Artificial chemistries are created and studied in order to understand fundamental properties of chemical systems, including prebiotic evolution, as well as for developing chemical computing systems. Artificial chemistry is a field within computer science wherein chemical reactions-often biochemical ones-are computer-simulated, yielding insights on evolution, self-assembly, and other biochemical phenomena. The field does not use actual chemicals, and should not be confused with either synthetic chemistry or computational chemistry. Rather, bits of information are used to represent the starting molecules, and the end products are examined along with the processes that led to them. The field originated in artificial life but has shown to be a versatile method with applications in many fields such as chemistry, economics, sociology ...
We imaged the purified OT complex by cryo-EM and obtained a first snapshot of the complex by computer reconstruction of the micrographs, said Li, a cryo-EM expert.. In cryo-EM, he explained, samples are frozen in vitreous ice and maintained at cryogenic temperatures (-274° Fahrenheit) using liquid nitrogen while the samples are photographed in the high vacuum of an electron microscope. The sophisticated cryo-EM machine resides in Brookhaven Labs biology department. Li and his collaborators also measured the mass of the OT complex at Brookhavens Scanning Transmission Electron Microscope (STEM) facility.. The structure deciphered by the group helps to explain many biochemical phenomena observed about the enzyme complex over the past two decades. It also offers hints as to how the enzyme performs its various jobs, from recognizing the sugar molecules to be added to the protein, scanning the protein as it is formed to identify the sites where sugars should be attached, and transferring the sugar ...
