  1. Heads and Tails: Molecular Imagination and the Lipid Bilayer, 1917–1941.Daniel Liu - 2018 - In Karl Matlin, Jane Maienschein & Manfred Laubichler (eds.), Visions of Cell Biology: Reflections Inspired by Cowdry's General Cytology. University of Chicago Press. pp. 209-245.
    Today, the lipid bilayer structure is nearly ubiquitous, taken for granted in even the most rudimentary introductions to cell biology. Yet the image of the lipid bilayer, built out of lipids with heads and tails, went from having obscure origins deep in colloid chemical theory in 1924 to being “obvious to any competent physical chemist” by 1935. This chapter examines how this schematic, strictly heuristic explanation of the idea of molecular orientation was developed within colloid physical (...)

  2. Thyroid Panel and Modified Lipid Profile among Sudanese Patients with Coronary Heart Disease.Lubna S. B. Mohmmedzain, Sahar A. M. Abdelrahman, Zainab E. M. Ibrahim, Zainab F. E. Ahmed & Mohamed A. M. Salih - 2019 - International Journal of Academic Health and Medical Research (IJAHMR) 3 (3):1-7.
    Abstract: The analytical, comparative cross-sectional study was conducted to assess the thyroid profiles and modified lipid profiles levels among Sudanese patients with coronary heart disease performed on forty-one patients with coronary heart disease as test group collected from Sudan Heart Center, Al rebat teaching hospital and Al mawada hospital in Khartoum state, during the period between November 2017 and May 2018. Furthermore, the test group compared with forty-one apparently healthy volunteers as control group was selected with the same inclusion (...)

    Regeneration of Hydra from aggregated cells.Alfred Gierer, S. Berking, H. Bode, C. N. David, K. Flick, G. Hansmann, H. Schaller & E. Trenkner - 1972 - Nature New Biology 239:98-101.
    • Aggregates of previously isolated cells of Hydra are capable, under suitable solvant conditions, of regeneration forming complete animals. In a first stage, ecto- and endodermal cells sort out, producing the bilayered hollow structure characteristic of Hydra tissue; thereafter, heads are formed (even if the original cell preparation contained no head cells), eventually leading to the separation of normal animals with head, body column and foot. Hydra appears to be the highest type of organism that allows for regeneration of the (...)

  4. Oxidative stress and inflammation induced by environmental and psychological stressors: a biomarker perspective.Pietro Ghezzi, Luciano Floridi, Diana Boraschi, Antonio Cuadrado, Gina Manda, Snezana Levic, Fulvio D'Acquisito, Alice Hamilton, Toby J. Athersuch & Liza Selley - 2018 - Antioxidants and Redox Signaling 28 (9):852-872.
    The environment can elicit biological responses such as oxidative stress (OS) and inflammation as a consequence of chemical, physical, or psychological changes. As population studies are essential for establishing these environment-organism interactions, biomarkers of OS or inflammation are critical in formulating mechanistic hypotheses. By using examples of stress induced by various mechanisms, we focus on the biomarkers that have been used to assess OS and inflammation in these conditions. We discuss the difference between biomarkers that are the result of a (...)

    The human revolution: Editorial introduction to 'honest fakes and language origins' by Chris Knight.Charles Whitehead - 2008 - Journal of Consciousness Studies 15 (10-11):226-235.
    It is now more than twenty years since Knight (1987) first presented his paradigm-shifting theory of how and why the ‘human revolution’ occurred — and had to occur — in modern humans who, as climates dried under ice age conditions and African rainforests shrank, found themselves surrounded by vast prairies and savannahs, with rich herds of game animals roaming across them. The temptation for male hunters, far from any home base, to eat the best portions of meat at the kill (...)

    Laparoscopic Ovarian Drilling Improve Endometrial Receptivity by Increasing Production of Endometrial Metabolites.Cemil Karakuş - 2022 - European Journal of Therapeutics 28 (1):62-66.
    Objective: Laparoscopic ovarian drilling normalizes ovulation by reducing cortical thickening, lowering androgen production, and regulating luteinizing hormone pulse frequency. On the other hand, the effect of laparoscopic ovarian drilling on the endometrium is unknown. This study was planned to investigate the changes in the functional markers of choline, creatine, lactate, and lipid metabolites of the endometrium before and after laparoscopic ovarian drilling in women with polycystic ovary syndrome. -/- Methods: Twenty women diagnosed with clomiphene-resistant polycystic ovary syndrome who did (...)

  7. Effects of Moderate Exercise Training On ApoE And ApoCIII In Metabolic Syndrome.Kutluhan Ertekin, Metin Baştuğ & Asena Gökçay Canpolat - 2023 - European Journal of Therapeutics 29 (1):65-73.
    Introduction: Metabolic syndrome (MetS) is an endocrinopathy with a combination of cardiovascular and metabolic compounds. In our study, it is expected to obtain results showing that mortality rate, loss of workforce, and treatment costs due to disorders caused by MetS can be reduced by physical exercise. The study analyses the effect of moderate exercise training on this Apolipoprotein E (ApoE), Apolipoprotein CIII (ApoCIII), adiponectin, resistin, interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α) which are thought to have a role in the (...)

    A pressure-reversible cellular mechanism of general anesthetics capable of altering a possible mechanism of consciousness.Kunjumon Vadakkan - 2015 - Springerplus 4:1-17.
    Different anesthetics are known to modulate different types of membrane-bound receptors. Their common mechanism of action is expected to alter the mechanism for consciousness. Consciousness is hypothesized as the integral of all the units of internal sensations induced by reactivation of inter-postsynaptic membrane functional LINKs during mechanisms that lead to oscillating potentials. The thermodynamics of the spontaneous lateral curvature of lipid membranes induced by lipophilic anesthetics can lead to the formation of non-specific inter-postsynaptic membrane functional LINKs by different mechanisms.

    A framework for the first‑person internal sensation of visual perception in mammals and a comparable circuitry for olfactory perception in Drosophila.Kunjumon Vadakkan - 2015 - Springerplus 4 (833):1-23.
    Perception is a first-person internal sensation induced within the nervous system at the time of arrival of sensory stimuli from objects in the environment. Lack of access to the first-person properties has limited viewing perception as an emergent property and it is currently being studied using third-person observed findings from various levels. One feasible approach to understand its mechanism is to build a hypothesis for the specific conditions and required circuit features of the nodal points where the mechanistic operation of (...)

  10. Changes in serum biochemistry of fish, Channa punctatus in response to nickel toxicity.Mukul Sinha - 2021 - IJAR 7 (8):459-461.
    The present investigation has been designed to study the effect of sub lethal concentrations of Nickel on the serum metabolites of Channa punctatus after exposure to 45 days. The present study shows that serum metabolites such as glucose and protein were significantly decreased while lipid was significantly increased. Thus, the result provides an overview of the manipulation of fish, Channa punctatus as a biomarker of heavy metals through alternation in serum biochemical parameters.
