To understand gene function, it is necessary to compare cells carrying the mutated target gene with normal cells. In most biomedical studies, the cells being compared are in different mutant and control animals and, therefore, do not experience the same epigenetic changes and tissue microenvironment. The experimental induction of genetic mosaics is essential to determine a gene cell-autonomous function and to model the etiology of diseases caused by somatic mutations.

However, the Cre-loxP technology has several drawbacks, including weak activity, leakiness, toxicity, and low reliability of existing Cre-reporters. This is mainly because different genes flanked by loxP sites (floxed) vary widely in their sensitivity to Cre-mediated recombination.

Targeting the Notch receptors or Delta-like ligand 4 (Dll4) dysregulates angiogenesis. Here, by analyzing single and compound genetic mutants for all Notch signaling members, we find significant differences in the way ligands and receptors regulate liver vascular homeostasis.

In our work, we present a narrative review, which includes 20 observational studies that provide data on the blood levels of vitamin D, folate, or fatty acids of children diagnosed with ASD (Autism Spectrum Disorder-AG group), and of a control group (children without this disorder-CG group). The main characteristics and results are presented in a summary table.

The aims of the study are to adapt the Healthcare-workers' Aggressive Behavior Scale-Users (HABS-U) to mental health professionals, to establish the frequency of exposure to hostile indicators and to determine which professional group is most exposed.
Method: Study through qualitative and quantitative methodology in MH professionals of the Region of Murcia (Spain).
Improved methods for manipulating and analyzing gene function have provided a better understanding of how genes work during organ development and disease. Inducible functional genetic mosaics can be extraordinarily useful in the study of biological systems; however, this experimental approach is still rarely used in vertebrates. This is mainly due to technical difficulties in the assembly of large DNA constructs carrying multiple genes and regulatory elements and their targeting to the genome.

Specific clotting activity of seed extract was 200 times higher than that of flower extract.

The most common and prominent symptoms of apnea is excessive diurnal drowsiness, as well asin addition to alterations of the memory and concentration, irritability, headache, and depression, among others. To date, no known studies have related OSAS with another type of more serious psychiatric disorder, such as psychotic symptoms.
