Meteoritic Abundances of Fatty Acids and Potential Reaction Pathways in Planetesimals [PDF]
The origin of fatty acids on the prebiotic Earth is important as they likely formed the encapsulating membranes of the first protocells. Carbon-rich meteorites (i.e., carbonaceous chondrites) such as Murchison and Tagish Lake are well known to contain these molecules, and their delivery to the early planet by intense early meteorite bombardments ...

Tranexamic Acid Inhibits Angiogenesis and Melanogenesis in Vitro by Targeting VEGF Receptors
Melasma is a common but complex skin condition concerning cosmetic problems. Tranexamic acid (TA) has been proved to be effective in treatment of melasma with still unclear mechanisms. Here, we show that VEGF165 enhanced the expression of VEGF receptors (

Effect of tranexamic acid on mortality in patients with haemoptysis: a nationwide study
Background Although tranexamic acid is widely used in patients with haemoptysis, whether it improves mortality has not been well investigated. The aim of this study was to evaluate the effect of tranexamic acid on in-hospital mortality among patients ...

Background: Tranexamic acid reduces blood loss in surgery and the risk of death in trauma patients. Meta-analyses of small trials suggest that tranexamic acid decreases the number of deaths from gastrointestinal bleeding, but these meta-analyses are ...

Exposure-Response Relationship of Tranexamic Acid in Cardiac Surgery.
BACKGROUND It is unclear whether high-dose regimens of tranexamic acid in cardiac surgery (total dose, 80 to 100 mg/kg) confer a clinical advantage over low-dose regimens (total dose, approximately 20 mg/kg), particularly as tranexamic acid-associated ...

Doubly robust treatment effect estimation with missing attributes [PDF]
Missing attributes are ubiquitous in causal inference, as they are in most applied statistical work. In this paper, we consider various sets of assumptions under which causal inference is possible despite missing attributes and discuss corresponding approaches to average treatment effect estimation, including generalized propensity score methods and ...

Geometric-algebraic approach to aqueous solutions of diprotic acids and its buffer mixtures [PDF]
A closed-form analytical expression for $\ce{[H3O+]}$ has been obtained for aqueous solutions of diprotic acids and its soluble salts. This formula allows to calculate the pH of aqueous solutions of diprotic acids, their buffer solutions, and the titrations of these two by a strong base, from the values of p$K_1$, p$K_2$, and the effective ...

Background and Aim: Dacryocystorhinostomy (DCR) is one of the most common ophthalmologic surgeries frequently associated with bleeding. Considering lack of a similar study, we decided to evaluate and compare the effects of remifentanil and tranexamic ...
