Role of Citicoline in the Management of Traumatic Brain Injury
pharmaceuticals Review Role of Citicoline in the Management of Traumatic Brain Injury Julio J. Secades Medical Department, Ferrer, 08029 Barcelona, Spain; [email protected] Abstract: Head injury is among the most devastating types of injury, specifically called Traumatic Brain Injury (TBI). There is a need to diminish the morbidity related with TBI and to improve the outcome of patients suffering TBI. Among the improvements in the treatment of TBI, neuroprotection is one of the upcoming improvements. Citicoline has been used in the management of brain ischemia related disorders, such as TBI. Citicoline has biochemical, pharmacological, and pharmacokinetic characteristics that make it a potentially useful neuroprotective drug for the management of TBI. A short review of these characteristics is included in this paper. Moreover, a narrative review of almost all the published or communicated studies performed with this drug in the management of patients with head injury is included. Based on the results obtained in these clinical studies, it is possible to conclude that citicoline is able to accelerate the recovery of consciousness and to improve the outcome of this kind of patient, with an excellent safety profile. Thus, citicoline could have a potential role in the management of TBI.

Clinical Significance of Small Molecule Metabolites in the Blood of Patients
www.nature.com/scientificreports OPEN Clinical signifcance of small molecule metabolites in the blood of patients with diferent types of liver injury Hui Li1,2,5, Yan Wang1,5, Shizhao Ma1,3, Chaoqun Zhang1,4, Hua Liu2 & Dianxing Sun1,4* To understand the characteristic of changes of serum metabolites between healthy people and patients with hepatitis B virus (HBV) infection at diferent stages of disease, and to provide reference metabolomics information for clinical diagnosis of liver disease patients. 255 patients with diferent stages of HBV infection were selected. 3 mL blood was collected from each patient in the morning to detect diferences in serum lysophosphatidylcholine, acetyl-l-carnitine, oleic acid amide, and glycocholic acid concentrations by UFLC-IT-TOF/MS. The diagnostic values of four metabolic substances were evaluated by receiver operating characteristic (ROC) curve. The results showed that the optimal cut-of value of oleic acid amide concentration of the liver cirrhosis and HCC groups was 23.6 mg/L, with a diagnostic sensitivity of 88.9% and specifcity of 70.6%. The diagnostic efcacies of the three substances were similar in the hepatitis and HCC groups, with an optimal cut-of value of 2.04 mg/L, and a diagnostic sensitivity and specifcity of 100% and 47.2%, respectively. The optimal cut-of value of lecithin of the HBV-carrier and HCC groups was 132.85 mg/L, with a diagnostic sensitivity and specifcity of 88.9% and 66.7%, respectively. The optimal cut-of value of oleic acid amide of the healthy and HCC groups was 129.03 mg/L, with a diagnostic sensitivity and specifcity of 88.4% and 83.3%, respectively. -

One of the most common compounds in these venomous cocktails are pore-forming proteins, a family of toxins whose activity relies on the disruption of the plasmatic membranes by forming pores. The venom of sea anemones, belonging to the oldest lineage of venomous animals, contains a large amount of a characteristic group of pore-forming proteins known as actinoporins. They bind specifically to sphingomyelin-containing membranes and suffer a conformational metamorphosis that drives them to make pores. This event usually leads cells to death by osmotic shock. Sticholysins are the actinoporins produced by Stichodactyla helianthus. Three different isotoxins are known: Sticholysins I, II, and III. -

IV. Pulmonary Lecithin Synthesis in the Human Fetus and Newborn and Etiology of the Respiratory Distress Syndrome Louis GLUCK1391, MARIE V. KULOVIGH, ARTHUR I. EIDELMAN, LEANDRO CORDERO, AND AIDA F. KHAZIN Department of Pediatrics, University of California, San Diego, School of Medicine, La Jolla, California, USA Extract The surface-active complex lining alveoli in normal lung lowers surface tension on ex- piration, thus preventing alveolar collapse. Surface activity follows a developmental timetable. Infants with idiopathic respiratory distress syndrome (RDS) almost ex- clusively are prematurely born, and their lungs lack adequate surface activity and are deficient in the principal surface-active component, lecithin. This deficiency implies that RDS is a "disease of development," with fetal and neonatal timetables for lecithin synthesis. The biosynthesis of lung lecithin in the living human infant was studied by examining phospholipids in lung effluent (pharyngeal aspirates, mucus), which have identical phospholipids to those in lung lavage (alveolar wash). The fatty acid esters of isolated lecithin and phosphatidyl dimethylethanolamine (PDME) were examined. The fi-carbon fatty acids are indicators of the primary pathways of synthesis of lecithin: (1) a preponderance of palmitic acid signifying cytidine diphosphate choline (CDP-choline) + D-a,{3-diglyceride -+lecithin (choline incorporation pathway) and (2) a preponder- ance of myristic acid signifying phosphatidyl ethanolamine (PE) + 2 CH3 —»• PDME + CHZ —> lecithin (methylation pathway). Fetal lung of 18 and 20 weeks showed slight incorporation by GDP-choline pathway, absence of PDME, and almost no methylation. -

Gut microbial metabolism of choline results in the production of trimethylamine (TMA), which, upon absorption by the host is converted into trimethylamine-N-oxide (TMAO) in the liver. A high accumulation of both components is related to cardiovascular disease, inflammatory bowel disease, non-alcoholic fatty liver disease, and chronic kidney disease. However, the relationship between the microbiota production of these components and its impact on these diseases still remains unknown. In this review, we will address which microbes contribute to TMA production in the human gut, the extent to which host factors (e.g., the genotype) and diet affect TMA production, and the colonization of these microbes and the reversal of dysbiosis as a therapy for these diseases. -
Spray-Dried Bioadhesive Formulations for Pulmonary Delivery
SPRAY-DRIED BIOADHESIVE FORMULATIONS FOR PULMONARY DELIVERY BY HUNER KAMAL OMER A THESIS SUBMITTED IN PARTIAL FULFILMENT FOR THE REQUIRMENTS OF THE DEGREE OF DOCTOR OF PHILOSOPHY AT THE UNIVERSITY OF CENTRAL LANCASHIRE July/2014 ABSTRACT This study describes developments and in vitro characterisation of lipid microparticles prepared using spray-drying for drug delivery to the lung via dry powder inhalers. Bioadhesive formulations such as prochitosome or chitosome powders have been introduced to overcome the drawbacks of liposome instability and potentially provide significant increase in the residence time of drug in the lung. Mannitol or lactose monohydrate (LMH) aqueous solutions were spray dried at inlet temperatures of 90, 130, 170 or 210ºC. Soy phosphatidylcholine and cholestrol (1:1 mole ratio) were used in all formulations. Cholesterol was added to increase vesicle membrane rigidity. Proliposomes containing salbutamol sulphate (SS) were prepared by incorporating various lipid:carrier (mannitol or LMH; 1:2, 1:4, 1:6, 1:8 and 1:10 w/w). Prochitosomes including SS or beclomethason dipropionate (BDP) were prepared by adding various chitosan glutamate:lipid ratios of 1:10, 2:10, 3:10 and 5:10 w/w. Chitosomes, including various cryoprotectants (mannitol, LMH, trehalose or sucrose), were prepared by including chitosan glutamate to liposomes generated from ethanol-based proliposomes in the ratio of 3:10 w/w chitosan to lipid. The spray-drying parameters for generation of dry powders were optimised by using an inlet temperature of 120ºC, outlet temperature of 73 ± 3°C, aspirator rate of 100%, suspension feed rate of 11%, and spray flow rate of 600 L/h using B-290 Buchi mini spray-dryer.
