activity of thymidine kinase during the cell cycle in tetrahymena pyriformis.the presence of thymidine kinase has recently been reported in tetrahymena pyriformis. the activity pattern for this enzyme was investigated during the cell cycle in both the one heat-shock per cell generation and the starvation-refeed system. thymidine kinase was found to be a peak enzyme during s-phase in both situations. nucleoside phosphotransferase was a continuous enzyme in the one heat-shock per cycle system, however, it closely paralleled the thymidine kinase curve during starvation and ...1998104828
protein-calorie malnutrition in patients with colorectal cancer.protein-calorie malnutrition, as determined by anthropometric measures and laboratory tests, was assessed in 17 preoperative patients with colorectal cancer and 47 control patients. the cancer patients had significant deficits in visceral protein and skeletal muscle and no deficit in fat stores. greater attention should be given to preoperative nutritional assessment and to the correction of protein deficits.1998104851
bronchial mucosal permeability.the tracheobronchial epithelium has well-developed tight junctions which on a morphologic basis should be markedly resistant to penetration by protein molecules. despite this, antigen inhalation in monkeys allergic to ascaris suum results in the rapid onset of pulmonary physiologic changes. recent studies in man and animals have shown that a substantial number of mast cells exist in the bronchial lumen and epithelium. we suggest that antigen-antibody interaction initially occurs on these superfi ...1979104888
passage of immunoglobulins from plasma to the oral cavity in rhesus monkeys.the passage of immunoglobulin from plasma to the oral cavity was studied in rhesus monkeys. immunoglobulins g, a and m were purified from pooled rhesus monkey serum, radiolabelled with 125i and injected intravenously into twelve monkeys. sequential samples of oral fluids were taken over a 24 h period and were assayed for radioactivity. radioactivity could be detected in crevicular fluid washings after 0.5 h in monkeys injected with igg and iga, and after 2 h in monkeys given igm. maximal levels ...1978104924

muscle responses and monosynaptic reflexes in falling monkey. role of the vestibular system.the free fall has been used in our laboratory as a way to test vestibular function in baboons in order to quantify vestibular compensation in the hemilabyrinthectomized animal. this study presents only those results that concern the contribution of the vestibular system to muscle responses due to sudden fall. emg activity was recorded from the fully conscious animal using chronic electrodes implanted in various muscles. spinal monosynaptic reflexes (hoffmann's and tendon reflexes) were studied i ...1978105128
some clinical consequences of red cell incompatibility: the bradshaw lecture 1978.most deaths from red cell incompatibility are due either to the transfusion of abo-incompatibile red cell or to rh-haemolytic disease of the newborn; almost all the deaths are preventible. it seems that approximately 1 in 5,000 recipients receive abo-incompatible blood, a figure which implies that donor and/or recipient may be mis-identified in as many as 1 in 1,5000 transfusions. another serious consequence of mis-identification is the transfusion of rh-positive blood to an rh-negative female w ...1998105132
evaluation of caged mating behavior in macaca fascicularis.studies were undertaken to characterize the basic behavioral parameters of a breeding colony of macaca fascicularis under caged conditions. the female reproduction performance index and the success ratio were found to correlate with mating behavior relating to cyclicity in females with cycles of less than 30 days. these evaluations proved to be useful in the selection of animals based on sexual vigor.1998105139

an anthranilate synthase of the extreme aminase type in a species of blue-green bacteria (algae).anthranilate synthase of agmenellum quadruplicatum, a unicellular species of blue-green bacteria, consists of two nonidentical subunits. a 72,000 dalton protein has aminase activity but is incapable of reaction with glutamine (amidotransferase) unless a second protein (18,000 molecular weight) is present. the small subunit was first detected through its ability to complement a partially purified aminase subunit from bacillus subtilis to produce a hybrid complex capable of amidotransferase functi ...1978105718
genetic and biochemical aspects of trehalase from drosophila melanogaster.only one molecular form of trehalase (e.c. 3.2.1.28) was detectable in adult drosophila melanogaster by polyacrylamide gel electrophoresis and isoelectric focusing. an examination of duplication- and deletion-bearing aneuploids exhibiting dosage sensitivity indicated that the enzyme is encoded by a gene, treh+, located between 55b and 55e of the second chromosome. the tissue-specific soluble and particulate forms of trehalase appear to be manifestations of a single protein encoded by a single ge ...1998105719
the necessity of magnesium cation for acid assistance aglycone departure in catalysis by escherichia coli (lacz) beta-galactosidase.1. removal of mg2+ from escherichia coli (lacz) beta-galactosidase slightly increases the rate of hydrolysis of galactosyl pyridinium salts, but decreases the rate of hydrolysis of arylgalactosides. 2. fair correlation of logkcat. and log (km) with the pka of aglycone is now observed for arglygalactosides, as well as for glycosyl pyridinium salts. 3. degalactosylation of mg2+-free enzyme is the rate-limiting step in the hydrolysis of 2,4-dinitrophenyl galactoside. 4. alpha-deuterium kinetic isot ...1978105722
relationship between biotin-binding proteins from chicken plasma and egg yolk.the plasma of laying hens contains a specific biotin-binding protein that appears to be identical with an egg-yolk biotin-binding protein. both proteins are saturated with biotin and require elevated temperatures to effect the exchange of [14c]biotin for the protein-bound vitamin. the heat-exchange curve in each case is the same and differs sharply from that of avidin, the egg-white biotin-binding protein. on sephadex g-100 gel filtration, plasma and yolk biotin-binding proteins were each eluted ...1978105724
drosophila melanogaster lacks eye-pigment binding proteins.drosophila melanogaster contains no detectable eye-pigment binding proteins, and the previous evidence for the presence of such protein in the cecropia moth is probably not valid. the major brown pigment of drosophila (and of cecropia), dihydroxanthommatin, behaves as a high molecular weight compound in sephadex chromatography, thus leading to false conclusions.1998105753
mutual homology of mouse immunoglobulin gamma-chain gene sequences.we have assessed the relative homology of mouse immunoglobulin heavy-chain gene sequence using complementary dnas (cdnas) synthesized against gamma-chain mrnas (gamma 1, gamma 2a, gamma 2b, and gamma 3) purified from mouse myelomas. cdnas complementary to the gamma-chain mrnas did not cross-hybridize with the mu- and alpha-chain mrnas, whereas they cross-hybridized to significant extents (22--66%) with the gamma-chain mrnas of other subclasses. the heterologous hybrids formed, however, melt at 5 ...1979105754

multiple sclerosis: immunochemical studies on the demyelinating serum factor.sera from patients with multiple sclerosis (ms) frequently produce demyelination of central nervous system tissue cultures. the nature of the factors responsible for demyelination is not as yet clearly established. however, several authors previously reported, in in vivo and in vitro models, demyelinating activity in igg fractions isolated from sera and cerebrospinal fluid of ms patients14,42,48. we found the demyelinating activity of ms sera to be extremely labile to conventional biochemical tr ...1979105780
