Aim: To review the initial effectiveness of bovine lipid extract surfactant (BLES) for the treatment of respiratory distress syndrome in preterm infants.
Methods And Results: A retrospective review of data collected from infants born <37-week gestation with respiratory distress syndrome treated with BLES between February 1, 2015 and March 1, 2016. Data were analyzed to determine the timing of initial dose, the length of time to wean the fraction of inspired oxygen (FiO) concentration to 0.21 following initial dose, and the number of repeated doses given during hospital admission. Infants were subgrouped by gestational age stratum, 23 to 27 weeks (group 1), 28 to 31 weeks (group 2), and 32 to 36 weeks (group 3). Ninety-eight infants received the surfactant during the study period. After applying exclusion criteria, 77 infants were analyzed. Mean (SD) gestational age was 28 (4) weeks, and mean (SD) birth weight was 1250 (602) g. Initial dose of BLES was given at a median (interquartile range) time of 29 (19-43) minutes in group 1, 150 (20-615) minutes in group 2, and 990 (53-2025) minutes in group 3. Median (interquartile range) length of time to wean the FiO concentration to 0.21 was 14 (5-56) minutes, 10 (5-53) minutes, and 10 (5-38) minutes in groups 1, 2, and 3, respectively. Ten infants required repeated doses.
Conclusion: Given the rapid response of BLES in all the groups, careful monitoring of ventilator parameters is paramount to allow for rapid weaning and early extubation to avoid lung injury associated with mechanical ventilation.

The mammalian target of rapamycin (mTOR) signaling pathway is activated by luteinizing hormone in preovulatory follicle. However, its impact on ovulation remains inadequately explored. Utilizing in vivo studies and in vitro fertilization, we demonstrated that the negative effect of inhibition of mTOR signaling by rapamycin on oocyte quality during the ovulatory phase, with a notable decrease in the total cell count of blastocysts, a reduction in gastrula size, and fetal degeneration on the 16th day of gestation while not affecting ovulated oocyte count or granulosa cell luteinization.

This scoping review focuses on drug delivery systems based on soft materials designed for the administration of drugs with anti-Trichomonas vaginalis activity. It primarily examines their use in addressing human trichomoniasis, exploring their physicochemical characteristics, in vitro and in vivo evaluation and identifying existing challenges and gaps. Given the economic burden and the One Health approach, formulations developed aiming at treating animal infections - cattle and poultry - were also discussed.

Research into nanoparticle interactions with biomolecules has become increasingly important in nanomedicine. While lipid nanoparticles (LNPs) are widely used as drug delivery systems, there remains a gap in understanding their fate in circulation, which is crucial for selecting appropriate lipids during formulation development. This study is the first to use Asymmetric Flow Field Flow Fractionation (AF4) to compare two types of LNPs: MC3-LNPs and SM-102-LNPs, and their interactions with a model protein, bovine serum albumin (BSA).

Modification of silica interfaces by covalent attachment of functional ligands is a primary means of controlling the interfacial chemistry of porous silicas used in separations, environmental cleanup, and biosensing. Recently, modification of hydrophobic, -alkyl-silane-functionalized interfaces has been achieved through self-assembly of zwitterionic phospholipids or mixed-charged surfactants to form "hybrid bilayers", producing interfaces that mimic lipid-bilayer partitioning and provide shape-selective partitioning of aromatic hydrocarbons. Charged headgroups, however, introduce electrostatic interactions that strongly influence the retention of ionizable solutes and require careful control over pH and ionic strength in the solution phase.
