Pediatric Blood &Cancer, EarlyView.ABSTRACT Background L‐asparaginase is a critical component in treatment protocols for pediatric acute lymphoblastic leukemia. Acute pancreatitis reactions can necessitate delays and, in some cases, discontinuation of L‐asparaginase, which compromises outcomes.

Journal of Biostatistics and EpidemiologyThe genetic variant of interest is referred to be a weak instrumental variable in Mendelian randomization If the relevance assumption is not met. By and large, a weak instrument bias occurs when there is insufficient statistical evidence to support an ...

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM
FEBS Letters, EarlyView.Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Impact of family size on education, child labor and female labor supply
Revista de Economía Política de Buenos Aires, 2018 This paper studies the impact of family size on education, child labor and mother’s labor market participation in Ecuador. Parent’s preferences and the sex mix of their children are exploited in an instrumental variables setting to overcome endogeneity ...

Non-Asymptotic Inference in Instrumental Variables Estimation
, 2017 This paper presents a simple method for carrying out inference in a wide variety of possibly nonlinear IV models under weak assumptions. The method is non-asymptotic in the sense that it provides a finite sample bound on the difference between the true ...

Jackknife instrumental variables estimation [PDF]
Journal of Applied Econometrics, 1999 Two-stage-least-squares (2SLS) estimates are biased towards OLS estimates. This bias grows with the degree of over-identification and can generate highly misleading results. In this paper we propose two simple alternatives to 2SLS and limited-information-maximum-likelihood (LIML) estimators for models with more instruments than endogenous regressors.

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Estimation with many instrumental variables [PDF]
Using many valid instrumental variables has the potential to improve efficiency but makes the usual inference procedures inaccurate. We give corrected standard errors, an extension of Bekker (1994) to nonnormal disturbances, that adjust for many ...
