BACKGROUND In 1993, Chitayat et al., reported a newborn with hyperphalangism, facial anomalies, and bronchomalacia. We identified three additional families with similar findings. Features include bilateral accessory phalanx resulting in shortened index fingers; hallux valgus; distinctive face; respiratory compromise. OBJECTIVES To identify the genetic aetiology of Chitayat syndrome and identi...
Abstract. The COVID-19 pandemic caused significant economic disruption in 2020 and severely impacted air traffic. We use a state-of-the-art Earth system model ensembles of tightly constrained simulations to evaluate the effect reductions aviation traffic on contrail radiative forcing climate 2020. In absence any COVID-19-pandemic-caused reductions, simulates effective (ERF) 62 ± 59 mW m−2 (2 st...
Abstract Modeling studies have shown that surface air temperature (SAT) increase in response to an the atmospheric CO 2 concentration is larger over land than ocean. This so-called land–ocean warming contrast, φ , defined as land–mean SAT change divided by ocean-mean change, a striking feature of global warming. Small heat capacity unlikely sole cause because land-ocean contrast found equilibri...
Volcanic and wildfire events between 2014 2022 injected ∼3.2 Tg of sulfur dioxide 0.8 smoke aerosols into the stratosphere. With injections at higher altitudes lower latitudes, simulated stratospheric lifetime 2014–2022 is about 50% longer than volcanic 2005–2013 injections. The global mean effective radiative forcing (ERF) −0.18 W m−2, ∼40% ERF period 1991–1999 with a large-magnitude eruption ...
Reactivity of natural killer (NK) cells to an established human renal cancer cell line (KU-2) was determined by cellular immunoadsorbant tech nique, utilizing human leukemia cell line (CCRF-CEM) which is highly sensi tive to NK cells. The influence of human alpha interferon (HuIFN-ƒ¿) on NK activity against KU-2 cells was also determined by microcytotoxicity assay. Percent cytotoxicity increase...
OBJECTIVE SIRT1 has pleiotropic metabolic functions. We investigated whether SIRT1 genetic variation is associated with obesity. RESEARCH DESIGN AND METHODS In 6,251 elderly subjects from the prospective, population-based Rotterdam Study, three single nucleotide polymorphisms (SNPs) in the SIRT1 gene were studied in relation to BMI and risk of obesity (BMI > or =30 kg/m(2)) and prospectively ...
BACKGROUND The AP2/ERF family includes a large number of developmentally and physiologically important transcription factors sharing an AP2 DNA-binding domain. Among them DREB1/CBF and DREB2 factors are known as master regulators respectively of cold and heat/osmotic stress responses. EXPERIMENTAL APPROACHES The manual annotation of AP2/ERF family from Eucalyptus grandis, Malus, Populus and V...
As a subfamily of the APETALA 2/ethylene response element binding protein (AP2/EREBP) transcription factor superfamily, the ethylene response factor (ERF) is widely involved in the regulation of growth and response to various abiotic stresses in plants, and has been shown to be the main transcription factor regulating transcription of the genes related to hypoxia and waterlogging stress. In thi...
