A procedure for making en face preparations of the mouse carotid artery and aorta is described. Such preparations, when immunofluorescently stained with specific antibodies, enable us to study localization of proteins and identification of cell types within the entire vascular wall by confocal microscopy.

Roux-en-Y Gastric Bypass Procedure: A Bariatric Surgical Procedure for Gastric Resectioning in Murine Model

2025
This video describes a bariatric surgery-Roux-en-Y procedure. This involves the cutting of the jejunum- the middle portion of the intestine- to generate two intestinal limbs. The biliary limb is attached to the existing intestinal loop and the alimentary limb is attached to the stomach, creating a gastric bypass. The gastric bypass created here helps to decrease the nutrient uptake and efficiently reduces body weight.

The lateral ventricle walls contain the largest germinal region in the adult mammalian brain. Traditionally, studies on neurogenesis in this region have relied on classical sectioning techniques for histological analysis. Here we present an alternative approach, the wholemount technique, which provides a comprehensive, en-face view of this germinal region.

A standardized mortar provides a consistent combination of cement, graded sand, and water for comparing cement performance. By reducing variation in the test mixture and specimen preparation, the method creates results that can be compared across cement products. This consistency makes the procedure useful for engineering quality control, product development, and compliance assessment.
The two measurements examine strength through sequential loading stages. First, flexural loading breaks each 40 × 40 × 160 mm prism and provides a flexural-strength result. The resulting halves are then tested in compression, allowing compressive strength to be measured from material produced during the same specimen test. Together, the results give complementary information about cement performance.
Cement strength changes as specimens cure, so testing age and curing conditions must be controlled to make results meaningful. BS EN 196-1 defines when measurements are taken and maintains consistent conditions before testing. This allows laboratories to compare strength development between cement products without confusing differences in curing history with differences in binder performance.
The procedure uses mortar made from cement, graded sand, and water, shaped into 40 × 40 × 160 mm prism specimens. These dimensions provide a defined form for the subsequent flexural and compressive measurements. Using the specified materials and geometry helps laboratories produce comparable results and limits variation caused by specimen preparation.
The workflow begins with preparing the standardized mortar and forming prism specimens. The prisms are then cured under controlled conditions until the defined testing ages. Each prism undergoes flexural loading and breaks into halves, after which those halves are subjected to compression testing. The sequence produces both flexural and compressive strength results for evaluation.
The method supports cement quality control, product development, and compliance assessment. Its standardized preparation, specimen dimensions, curing conditions, and loading sequence provide a common basis for comparing cement performance. Engineers can use the resulting strength information when evaluating cement products and selecting suitable binders for concrete and other cement-based construction materials.
