This protocol describes in detail how to specifically transfect different regions in the C57BL/6 central nervous system via in utero electroporation. Included in this protocol are detailed instructions for transfections of regions that develop into the cortex, hippocampus, thalamus, hypothalamus, lateral septal nucleus and striatum.

Endoscopic septoplasty is a time-honored surgical procedure with multiple variations. This paper focuses on a step-by-step surgical approach to perform a modified septoplasty procedure known as limited two-line resection. This surgical technique can be applied to correct a deviated nasal septum in the absence of an external nasal deformity.

This method describes the use of Infrared dye based imaging system for detection of H1N1 in bronchioalveolar lavage (BAL) fluid of infected mice at a high sensitivity. This methodology can be performed in a 96- or 384-well plate, requires <10 μl volume of test material and has the potential for concurrent screening of multiple pathogens.

Developmental studies in the mouse are hampered by the inaccessibility of the embryo during gestation. To promote the long-term culture of the embryonic heart at late stages of gestation, we developed a protocol in which the excised heart is cultured in a semi-solid, dilute Matrigel.
FAQs
Placement determines which septal pixels or voxels contribute to the result. The analyst outlines a defined cardiac septal region, then summarizes the signal or intensity values contained within it. Because the measured area is deliberately localized, the resulting number represents the selected septal tissue rather than an impression of the entire image, supporting focused analysis.
The measurable feature depends on the imaging modality and the clinical question. An ROI may support quantitative assessment of septal structure, motion, perfusion, or tissue characteristics by analyzing the relevant signal or intensity information. This flexibility allows the same region-based approach to contribute to different forms of cardiac image analysis.
Reference regions provide a basis for judging the septal measurement rather than viewing it in isolation. Comparing the selected septal ROI with another region can help characterize relative signal or intensity patterns. Such comparisons may make quantitative findings more interpretable in cardiac imaging studies and support evaluation of tissue or structural differences.
Standardized placement reduces variation in which portion of the septum is analyzed. More consistent positioning can improve measurement reproducibility when different patients are evaluated or when examinations are compared over time. This supports clearer interpretation of quantitative results and strengthens clinical research that relies on repeated or group-based cardiac measurements.
Application begins by identifying the cardiac septum on the imaging study and outlining the specified region of interest. The analysis then extracts pixel- or voxel-based signal or intensity values and compares them with a reference region or another examination when appropriate. The resulting measurements provide a quantitative summary for the selected septal area.
Measurements can be organized around a consistently selected septal region and evaluated against reference regions or serial examinations. This framework helps researchers examine whether quantitative values differ between patients or change across time. Its usefulness depends on maintaining comparable ROI placement and interpreting the values in relation to the imaging modality used.
The method is useful when investigators need quantitative information about the cardiac septum rather than visual description alone. It can support studies of cardiac disease by examining septal structure, motion, perfusion, or tissue characteristics, depending on the imaging modality. Standardized measurements also facilitate comparisons within research datasets and across serial examinations.
