Efficient preparation of hybrid biofuels from biomass-derived 5-(acetoxymethyl)furfural and petroleum-derived aromatic hydrocarbons.

Fuel candidates containing both petroleum-derived and biomass-derived molecules in their structural motifs ensure both feedstocks are used optimally and coherently. This work reports a straightforward and efficient preparation of 5-(arylmethyl)furfurals (AMFFs), 2-(arylmethyl)furans (AMFs), and 2-(arylmethyl)-5-methylfurans (AMMFs) as hybrid biofuels (or fuel oxygenates) starting from carbohydrate-derived 5-(acetoxymethyl)furfural (AcMF) and petroleum-derived aromatic hydrocarbons. The AMFFs were prepared by Friedel-Crafts reaction between AcMF and aromatic hydrocarbons (, BTX, mesitylene) by employing anhydrous ZnCl as the catalyst.

Comparative Evaluation of Multidetector Computed Tomography and Dual-Energy Computed Tomography Findings in Gastrointestinal Tuberculosis.

Aim: To compare multidetector computed tomography (MDCT) and dual-energy computed tomography (DECT) imaging findings in gastrointestinal (GI) tuberculosis.

Objective: To study imaging findings of MDCT and DECT in GI tuberculosis.

Methodology: All the patients falling in the sampling frame and fulfilling the eligibility criteria were clinically examined and demographic details, presenting complaints, medical history, history of anti-tubercular treatment (ATT) intake, personal habits, and family history of tuberculosis were noted.

Sphenoclival Intraosseous Lipoma: A Typical Lesion at an Atypical Location.

In this report, we present the case of a rare tumor in the sphenoclival region and discuss the potential pitfalls in its diagnosis and management. Intraosseous lipoma is a rare benign tumor, mostly accounting for 0.1% of all bone tumors.

Droplet digital PCR shows the D-Loop to be an error prone locus for mitochondrial DNA copy number determination.

Absolute quantification of mitochondrial DNA copy number (mCN) provides important insights in many fields of research including cancer, cardiovascular and reproductive health. Droplet digital PCR (ddPCR) natively reports absolute copy number, and we have developed a single-dye, multiplex assay to measure rat mCN that is accurate, precise and affordable. We demonstrate simple methods to optimize this assay and to determine nuclear reference pseudogene copy number to extend the range of mCN that can be measured with this assay.
