The anterolateral ligament of the knee is not a solid structure in human fetuses.

Purpose: The purpose of this study was to investigate if the anterolateral ligament of the knee (ALL) is present in the human fetus and describe its topography along with other structures of the region.

Methods: Forty human fetuses knee joints, at mean age 34 weeks (± 2.57 weeks), fixed in 10% formalin, were submitted to cross-sectional dissection and mesoscopic analysis.

Multiple arterial variations in the upper limb: description and clinical relevance.

Although arterial variations in the upper limb are usually found during anatomical dissections and clinical practice, multiple arterial variations associated with nervous variations along the limb is rare and clinically relevant. This paper described a combined anatomical variation involving the neurovasculature in the upper limb. A left upper limb dissection of a male cadaver with approximately 50-60 years of age, fixed in 10% formalin, was performed.

Low-dose chronic lead exposure increases systolic arterial pressure and vascular reactivity of rat aortas.

Chronic lead exposure induces hypertension affecting endothelial function. We investigated whether low-concentration lead exposure alters blood pressure and vascular reactivity, focusing on the roles of NO, oxidative stress, cyclooxygenase-derived vasoconstrictor prostanoids, and the local angiotensin-renin system. Aortic rings from 3-month-old Wistar rats were treated daily with lead acetate (first dose 4mg/100g, subsequent doses 0.

Cardiovascular adaptive responses in rats submitted to moderate resistance training.

The present study investigated the effects of 8 week of resistance training (RT) on hemodynamic and ventricular function on cardiac myosin ATPase activity, and on contractility of papillary muscles of rats. Groups: control (CO), electrically stimulated (ES), trained at 60% (TR 60%) and 75% of one repetition maximum (1RM) (TR 75%). Exercise protocol: 5 sets of 12 repetitions at 60 and 75% of 1RM, 5 times per week.
