Comparison of Haemodynamic Responses to Laryngeal Mask Airway Insertion and Laryngoscopy with Endotracheal Intubation in Adults Undergoing Elective Surgery at Muhimbili [PDF]
, 2012 Airway management is of utmost importance during delivery of general anaesthesia. Traditionally, laryngoscopy and endotracheal tube (ETT) insertion has been the mainstay in providing adequate airway management and delivering anaesthesia.

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation
FEBS Letters, EarlyView.Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

FEBS Letters, EarlyView.Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Prediction and measurement of wall insertion loss [PDF]
IEEE Transactions on Antennas and Propagation, 1999 A propagation loss study is presented to determine the attenuation of various building walls. An approximate model was developed for the propagation of a spherical electromagnetic wave through a building wall of known material properties. This model is based on the method of images and geometrical optics.

Improved insertion-loss tester [PDF]
, 1964 An improved test method accurately measures the insertion loss of RF components while avoiding amplifier drift. Currents are balanced across a bridge transformer with shorted probes and then with each component to be tested.

FEBS Letters, EarlyView.How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...
