Sodium Lauryl Sulfate, a Microbicide Effective Against Enveloped and Nonenveloped Viruses
Bibliographic record
Abstract
The number of individuals infected with human immunodeficiency virus (HIV) and other pathogens causing sexually transmitted diseases (STDs) is growing dramatically worldwide. Globally, heterosexual transmission may account for as much as 85-90% of new cases of HIV infection. Latex condoms represent an effective barrier against sexually transmitted pathogens, but unfortunately, their use is not generalized. Therefore, there is an urgent need to develop safe and potent topical microbicides under the control of women to efficiently reduce the spread of sexually transmitted infections. Sodium lauryl sulfate (SLS), an anionic surfactant with protein denaturing potency, is a potent inhibitor of the infectivity of several enveloped (Herpes simplex viruses, HIV-1, Semliki Forest virus) and nonenveloped (papillomaviruses, reovirus, rotavirus and poliovirus) viruses. The mechanism of action of SLS involves the solubilization of the viral envelope and/or the denaturation of envelope and/or capsid proteins. Studies have shown that SLS is not toxic for cultured cell lines of different origins at concentrations that inactivate HIV-1, herpes and human papillomavirus in vitro. In addition, intravaginal pretreatment of mice with a gel formulation containing SLS, completely protected animals against Herpes simplex virus type-2 infection. The gel formulation containing SLS was also well-tolerated following repeated intravaginal administrations to rabbits. Taken together, these data suggest that SLS represents a potential candidate for the use as a topical microbicide to prevent the sexual transmission of HIV-1, herpes, human papillomavirus and possibly other sexually transmitted pathogens. The impact of such a preventive tool on public health can be enormous.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
