The ocean's biota sequester atmospheric carbon dioxide (CO2) in part by producing dissolved organic matter (DOM) that persists in the ocean for millennia. This long-term accumulation of carbon may be facilitated by abiotic and biotic production of chemical structures that resist degradation, consequently contributing disproportionately to refractory DOM. Compounds that are selectively preserved...

Korf, Reid and Edelkamp initiated a line of research for developing methods (KRE and later CDP) that predict the number of nodes expanded by IDA* for a given start state and cost bound. Independent of that, Chen developed a method (SS) that can also be used to predict the number of nodes expanded by IDA*. In this paper we advance these prediction methods. First, we develop a variant of CDP that...

The cytochrome b heavy chain (gp91-phox) is expressed exclusively in terminally differentiating myelomonocytic cells. The human gp91-phox gene spans approximately 30 kilobases, and is divided into 13 exons. A ubiquitous factor that is indistinguishable from the CCAAT-binding factor CP1 interacts in vitro with the distal gp91-phox promoter CCAAT box motif. CP1 binding is prevented, however, by a...

The properties of cardiolipin synthase were investigated in mitochondria and submitochondrial fractions from etiolated mung bean (Vigna radiata L.) seedlings. Direct evidence is presented that the enzyme utilizes CDP-diacylglycerol in addition to phosphatidylglycerol for the synthesis of cardiolipin. Cardiolipin synthase had an alkaline pH optimum of about 9 and required divalent cations for ac...

A multicenter double-blind placebo-controlled study of cytidine 5'-diphosphocholine (CDP-choline) was conducted to evaluate possible clinical benefits of the drug in patients with acute, moderate to severe cerebral infarction. The patients included also suffered from moderate to mild disturbances of consciousness, and all were admitted within 14 days of the ictus. Patients were allocated random...

Background: Various recommendations exist concerning the discontinuation of contact and droplet precautions (CDP) for patients hospitalised with coronavirus disease 2019 (COVID-19). Some are based on repeated negative real-time polymerase chain reaction (RT-PCR) results, whereas other clinical criteria. The feasibility safety these poorly documented. Method: We conducted a retrospective study t...

Full or partial loss of function in the upper limb is an increasingly common due to sports injuries, occupational injuries, spinal cord injuries, and strokes. Typically treatment for these conditions relies on manipulative physiotherapy procedures which are extremely labour intensive. Although mechanical assistive device exist for limbs this is rare for the upper body. In this paper we describe...

Cyclodextrins (CDs) are well-known macrocyclic compounds in the fields of supramolecular and molecular recognition. For use as separation adsorption materials, water-soluble CDs must be modified into solid forms. Hybrid polymers consisting amorphous silica α- or β-CDs (propyl-modified α-CD, butyl-modified β-CD, ethylenediamine modified-βCD), designated propyl-α-CDP (2), butyl-β-CDP (3), EDA-β-C...
