  • Metabolism of D1-Valine and D1-Isovaline in the Normal
    Ai ABSTRACT OF ThE THESIS OF ___________ for (Naine) (Degree) (Majer) Date Thesis presented__._-J-9LJ-____ THE T i tie - - 9 .PY. NO.MAL RAT- Abstract Approved: (kiajor Professor) Up to the present time no in±ormation is available as to the role of di-valine in metabolism except that it is an ind.ispensllJle amino acid. and must be su.pplied in the diet of' the animal if' growth and. life is to contlnu.e. Experimental techniques that lately have been applied. to the stu.ay of other amino acids might yield sorne inform- ation in this problem and assign to di-valine a definite role as a glycogenic or as a ketone-prod.u.cing compound. The ketolytic properties of di-valine have beem dem- onstrated by the decrease in level of acetonuria of' fasting rats fed di-valine when the ketonaria arises from endogen- oua stores. These ketolrt1c results have been further substantiated when fasting rats were fed. sodium butyrate to heighten the already existing acetonu.ria. This ketolytic effect should derive its origin from the formation of' liver glycogen. Liver glycogen studies were carried. out to test this hypothesis. Small but sign- ificant amounts of glycogen were founa after feeding dl- valine. Thus, affording further proof' that di-valine may be considered a weakly glycogenic amino acid. No glycogen was found after feeding di-isovaline. Absorption studies were made and the rates of absorp- tion of di-valine and di-isovaline were found to confirm to the values previously reported by Chase and Lewis.

Methods A series of experiments examined the effects of systemic and spinally administered baclofen on bladder nociception in female anesthetized rats. Models of bladder nociception included those which employed neonatal and adult bladder inammation to produce bladder hypersensitivity. Results Cumulative intraperitoneal dosing (1–8 mg/kg IP) and cumulative intrathecal dosing (10–160 ng IT) of baclofen led to dose-dependent inhibition of visceromotor responses (VMRs) to urinary bladder distension (UBD) in all tested models. There were no differences in the magnitude of the analgesic effects of baclofen as a function of inammation versus no inammation treatments. Hemodynamic (pressor) responses to UBD were similarly inhibited by IT baclofen as well as UBD-evoked excitatory responses of spinal dorsal horn neurons. The GABAB receptor antagonist, CGP 35348, antagonized the antinociceptive effects of IT baclofen on VMRs in all tested models but did not affect the magnitude of the VMRs by itself suggesting no tonic GABAB activity was present in this preparation.

    Stereoselective Biocatalysis. A mature technology for the asymmetric synthesis of pharmaceutical building blocks Jesús Albarrán-Velo, Daniel González-Martínez and Vicente Gotor-Fernández* a Organic and Inorganic Chemistry Department, Biotechnology Institute of Asturias (IUBA), University of Oviedo, Avenida Julián Clavería s/n, 33006 Oviedo, Spain.

Abstract Biocatalysis is gaining increasing attention in the academic and industrial sector due to the possibility of developing highly stereoselective transformations in a sustainable manner. The creation of stereogenic centers in organic synthesis is not trivial and multiple approaches have been disclosed based on 1 organometallic and organocatalytic methods with the use of day by day more complex catalysts to induce asymmetry in selected transformations. The intrinsic chirality of enzymes makes them powerful tools for the development of stereoselective transformations, catalysing a wide range of chemical reactions due to the high abundance and diversity of enzymes in nature. In addition, the enormous advances in rational design and molecular biology methods have opened up the possibility to create more robust and versatile biocatalysts, which have improved the initial activities displayed by wild-type enzymes. Therefore, their applicability has been widely increased in terms of reaction conditions, substrate specificity, activity and selectivity among others. All these properties have attracted the industrial sector, which has taken advantage of the enzyme selectivities in multiple scenarios. Herein, the focus has been put in recent developments of stereoselective transformations for the synthesis of valuable building blocks towards the production of pharmaceuticals and biologically active natural products.

  • Dynamic Transitions in Neuronal Network Firing Sustained by Abnormal Astrocyte Feedback

Astrocytes play a crucial role in neuronal firing activity. Their abnormal state may lead to the pathological transition of neuronal firing patterns and even induce seizures. However, there is still little evidence explaining how the astrocyte network modulates seizures caused by structural abnormalities, such as gliosis. To explore the role of gliosis of the astrocyte network in epileptic seizures, we first established a direct astrocyte feedback neuronal network model on the basis of the hippocampal CA3 neuron- astrocyte model to simulate the condition of gliosis when astrocyte processes swell and the feedback to neurons increases in an abnormal state. We analyzed the firing pattern transitions of the neuronal network when astrocyte feedback starts to change via increases in both astrocyte feedback intensity and the connection probability of astrocytes to neurons in the network.

  • A New Family of Extraterrestrial Amino Acids in the Murchison Meteorite
    www.nature.com/scientificreports OPEN A new family of extraterrestrial amino acids in the Murchison meteorite Received: 16 November 2016 Toshiki Koga1 & Hiroshi Naraoka1,2 Accepted: 8 March 2017 The occurrence of extraterrestrial organic compounds is a key for understanding prebiotic organic Published: xx xx xxxx synthesis in the universe. In particular, amino acids have been studied in carbonaceous meteorites for almost 50 years. Here we report ten new amino acids identified in the Murchison meteorite, including a new family of nine hydroxy amino acids. The discovery of mostly C3 and C4 structural isomers of hydroxy amino acids provides insight into the mechanisms of extraterrestrial synthesis of organic compounds. A complementary experiment suggests that these compounds could be produced from aldehydes and ammonia on the meteorite parent body. This study indicates that the meteoritic amino acids could be synthesized by mechanisms in addition to the Strecker reaction, which has been proposed to be the main synthetic pathway to produce amino acids. The extraterrestrial synthesis of amino acids is an intriguing discussion concerning the chemical evolution for the origins of life in the universe, because amino acids are fundamental building blocks of terrestrial life. The extrater- restrial amino acid distribution has been extensively examined using carbonaceous chondrites, which are the most chemically primitive meteorites containing volatile components such as water and organic matter, particularly the Murchison meteorite since it’s fall in 1969. The Murchison meteorite is classified as a CM2 (Mighei-type) chon- drite, moderately altered by aqueous activity on the parent body (e.g. ref. 1). Currently, a total of 86 amino acids have been identified in the Murchison meteorite as α, β, γ and δ amino structures with a carbon number between 2–4 C2 and C9 including dicarboxyl and diamino functional groups .
