Purification of residual glycerol recovered from biodiesel production

open access: yesSouth African Journal of Chemical Engineering, 2019
Transesterification is the most widely used reaction in the production of biodiesel. It involves the breaking of the triglyceride structure and the exchange of alkyl groups with the hydroxide groups of the alcohol to obtain the new ester (biodiesel).

Concurrent bi-lateral negotiation in agent systems

open access: yes, 2003
Bi-lateral negotiations represent an important class of encounter in agent-based systems. To this end, this paper develops and evaluates a heuristic model that enables an agent to participate in multiple, concurrent bi-lateral encounters in competitive ...

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

open access: yesFEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Structure‐forward targeting of claudins with synthetic binders

open access: yesFEBS Letters, EarlyView.
Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

open access: yesFEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

A comparison of time to achieve T5 blockade in lateral versus sitting position during elective cesarean section under spinal anesthesia: A randomized control trial

open access: yesJournal of Obstetric Anaesthesia and Critical Care, 2020
Context: Spinal anesthesia is the preferred anesthetic technique for cesarean section. Lateral and sitting positions are commonly used for performing subarachnoid block in parturients. Maternal positioning affects the spread of local anesthetic drugs and

Air-Q ILA as a conduit for orotracheal intubation in children: A randomized control trial for comparison between supine and lateral patient positions

open access: yesJournal of Anaesthesiology Clinical Pharmacology, 2022
Background and Aims: Airway management in children is always challenging and becomes a concern if required in the lateral position. We evaluated the efficacy of orotracheal intubation using the Air-Q intubating laryngeal Airway (Air-Q ILA) in supine and ...

Relationship between Speed and Lateral Position on Curves, September 2012 [PDF]

open access: yes, 2012
Excessive speed is often cited as a primary driver factor in crashes, particularly rural two-lane crashes. It has also been suggested that speed plays a significant role in crashes on curves. However, the relationship between speed and crashes on curves

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein

open access: yesFEBS Letters, EarlyView.
Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.
