Prevalence of gram-negative infections in cervico-facial sepsis [PDF]
, 2019 Magister Chirurgiae Dentium (MChD)In cervico-facial sepsis a substantial proportion of organisms are normally gram-negative staining of which the majority are anaerobes (Boyanova 2006 and Sanchez 2010).

Destabilization of α-helical structure in solution improves bactericidal activity of antimicrobial peptides: Opposing effects on bacterial and viral targets [PDF]
, 2016 We have previously examined the mechanism of antimicrobial peptides on the outer membrane of vaccinia virus. Here we show that the formulation of peptides LL37 and magainin-2B amide in polysorbate 20 (Tween-20™) results in greater reductions in virus ...

A predator-prey interaction between a marine Pseudoalteromonas sp. and Gram-positive bacteria [PDF]
, 2020 Predator-prey interactions play important roles in the cycling of marine organic matter. Here we show that a Gram-negative bacterium isolated from marine sediments (Pseudoalteromonas sp.

Riemannian Optimization for Skip-Gram Negative Sampling
, 2017 Skip-Gram Negative Sampling (SGNS) word embedding model, well known by its implementation in "word2vec" software, is usually optimized by stochastic gradient descent. However, the optimization of SGNS objective can be viewed as a problem of searching for
