Embryos of the annual killifish Austrofundulus limnaeus can enter into a state of metabolic dormancy, termed diapause, as a normal part of their development. In addition, these embryos can also survive for prolonged sojourns in the complete absence of oxygen. Dormant embryos support their metabolism using anaerobic metabolic pathways, regardless ...

Nanomaterials and nanotechnology is in forefront of materials research. Minimal attention is given to the potential participation of these materials in cell metabolism. Here we review recent efforts to understanding how carbon nanomaterials participate on cell metabolism. First, the introduction to the materials science of graphene, carbon nanotubes and metallic ...

Empirical studies give increased support for the hypothesis that the sporadic form of cancer is an age-related metabolic disease characterized by: (a) metabolic dysregulation with random abnormalities in mitochondrial DNA, and (b) metabolic alteration - the compensatory upregulation of glycolysis to offset mitochondrial impairments. This paper appeals to the theory ...

Adenosine deaminase, which catalyzes the deamination of adenosine and deoxyadenosine, plays a central role in purine metabolism. Indeed, its deficiency is associated with severe immunodeficiency and abnormalities in the functioning of many organs, including nervous system. We have mimicked an adenosine deaminase-deficient situation by incubating a human astrocytoma cell line ...

Xenotransplantation is one alternative to transplantation of human organs which has been investigated. It is generally accepted that the pig represents the most logical choice of animals to serve as organ donors for xenotransplantation. Moreover, the implementation of cloning by somatic cell nuclear transfer (SCNT) and transgenic techniques have resulted ...

To have large numbers of replicates in forensic entomology research, it is often necessary to freeze carcasses and thaw them before use in experiments. Research on the effects of freezing on decomposition is minimal in the literature and the effect that it has on insect (e.g., blow fly, beetle) activity ...

• A hallmark of the innate immune system of plants is the biosynthesis of low-molecular-weight compounds referred to as secondary metabolites. Tryptophan-derived branch pathways contribute to the capacity for chemical defense against microbes in Arabidopsis thaliana. • Here, we investigated phylogenetic patterns of this metabolic pathway in relatives of A. ...

Statins are competitive inhibitors of 3-hydroxy-3-methylyglutaryl-coenzyme A reductase and reduce low-density lipoprotein-C levels. Statins are well-tolerated drugs used for prevention of atherosclerosis and cardiovascular events. Statins possess anti-inflammatory, immunomodulatory, antioxidant, metabolic, and possible anticancer effects. Statins are reported to be effective against psoriasis, dermatitis, graft-versus-host disease, uremic pruritus, vitiligo, and ...

The effects of cyano substitution on cyclobutadiene are explored using density functional, coupled-cluster, CASSCF, and CASPT2 calculations. An isodesmic reaction is employed to gauge the relative stabilization (DeltaH(rxn) degrees) of cyclobutadienes with varying numbers of cyano groups. Although density functional theory predicts a relatively large stabilization for the addition of ...

After choosing between two alternatives, people perceive the chosen alternative as more attractive and the rejected alternative as less attractive. This postdecisional dissonance effect was eliminated by cleaning one's hands. Going beyond prior purification effects in the moral domain, physical cleansing seems to more generally remove past concerns, resulting in ...

an attractive smile helps people feel more self-confident and look younger. One of the more controversial aspects of smile attractiveness pertains to buccal corridor size. There is no previous study by those with artistic knowledge that has assessed the asthetic considerations of buccal corridor size. The purpose of this study ...

The enhancement/retardation of percutaneous permeation of diethyl-m-toluamide (DEET) in the presence of five percutaneous penetration modifiers (laurocapram, 3-dodecanoyloxazolidin-2-one (N-0915), S,S-dimethyl-N-(4-bromobenzoyl) iminosulfurane (DMBIS), S,S-dimethyl-N-(2-methoxycarbonylbenzenesulfonyl) iminosulfurane (DMMCBI) and tert-butyl 1-dodecyl-2-oxoazepan-3-yl-carbamate (TBDOC)) was investigated. These permeation modifiers were formulated in either water, propylene glycol (PG), ethanol or polyethylene glycol 400 (PEG 400). The ...

Trustee performance evaluations have been around for a long time, but now they might actually be useful.

We used an F1 hybrid of zucchini and its wild progenitor to examine the effects of pollen competition on progeny performance. We experimentally varied the intensity of pollen competition by depositing large or small pollen loads onto stigmas. To separate the effects of pollen competition from maternal effects, we excised ...

This report describes a study of consultation patterns of male and female partners in a group practice. It was found that fulltime principals of both sexes had similar levels of workload; that patients chose to consult a doctor of the same sex not only for sex-specific disorders but also for ...

This paper presents facts that disagree with the hypothesis of "a hydrophobic effect."

1 In nialamide-treated mice, L-5-hydroxytryptophan produced a dose-dependent hypoglycaemic response which was independent of whether the animals had been fed or fasted.2 This response was accompanied by a head-twitching response which was also dose-dependent.3 The hypoglycaemic response was not accompanied by an elevation in plasma immunoreactive insulin levels and was ...

This study assigned 81 non-naïve subjects, divided into low- and high-dose groups, to four experimental conditions (marijuana/marijuana, marijuana/placebo, placebo/marijuana and placebo/placebo) for two sessions separated by about one week. The low dose was 4.8 mg. Delta(9)-THC followed by 2.4 mg. one hour later. The high dose was 9.1 mg. followed ...

The importance of sunlight in bringing about not only photosynthesis in plants, but also other photochemical effects, is reviewed. More effort should be devoted to photochemical storage of the sun's energy without the living plant. There is no theoretical reason to believe that such reactions are impossible. Ground rules for ...

The effect of digoxin on A-V conduction in 19 patients with known disease of their conduction tissue was studied while a demand pacing system was in position. Fifteen had transient complete heart block after myocardial infarction and four had chronic intermittent complete heart block. The patients were studied on return ...

Treatment of Nitella antheridia with colchicine results in various sperm abnormalities, depending upon duration of exposure and subsequent recovery. Early effects of treatment include disappearance of spindle fibers and a cessation of ordered cell wall formation in dividing cells. Sperm released from antheridia treated for 24 hr and allowed to ...

The activity of carbenicillin against 200 strains of Pseudomonas aeruginosa was measured by a quantitative agar dilution method. Minimal inhibitory concentrations (M.I.C.'s) for five graded inocula were measured in terms of complete inhibition (CI) and reduced growth (RG). The M.I.C. decreased progressively as inocula were reduced, median values for the ...

Although revaccination with BCG has been practised for many years, the effects of this procedure have not been studied in detail. This paper gives some results from a study of the immediate effects of revaccination, i.e., the lesion developing at the site of injection and the tuberculin sensitivity present after ...

Fifteen homosexuals were treated with hypnosis. The patients were selected from a general psychiatric practice and had a long history of confirmed homosexual behaviour and showed no evidence of organic or psychotic illness. The type of hypnotic induction attempted in all cases is described. In those where a satisfactory depth ...

Thioridazine, chlorpromazine and trifluoperazine were administered to six psychiatric patients. Each was used in four dosage levels (thioridazine and chlorpromazine: 200, 400, 800 and 1200 mg. daily; trifluoperazine: 8, 16, 32, 64 mg. daily); and each increase in dosage was effected after four days of drug administration.Before the trial, twice ...
