background chronic sacroiliac (si) joint pain constitutes 16% to 30% of the total prevalence of chronic low back pain, which is commonly unilateral. apart from conservative management, various interventional pain management procedures have been reported. intraarticular deposteroid injection has been described as the most evidence-based, but different various radio frequency (rf) procedures have...

introduction: the horizontal bony canal in the lateral maxillary wall is the site of anastomosis between the arterial branches from the posterior superior alveolar artery (psaa) and the infraorbital artery. this anatomic structure is known as the ‘alveolar antral artery’.   materials and methods: we performed a literature review. the anatomic location of the alveolar antral artery in the latera...

The capture of patchily distributed nutrients by tree roots has received extensive research, but the fate of those nutrients has not. We performed experiments to determine if nutrient transport within tree species is preferentially transported from specific roots to specific branches. Saplings of five species with contrasting growth requirements were examined: two Betula species (B. papyrifera ...

The ramifications of the portal vein in the liver of horses were studied by using corrosion casting and gross dissection. The portal vein in the horse supplies the hepatic lobes by six major branches. The right lobe is supplied by three main branches, namely the dorsal diaphragmatic, the right caudodorsal and the right intermediate branches. The left branch supplies the left lateral and medial ...

BACKGROUND BL52 is located 3 cun lateral to the lower border of the spinous process of the L2 vertebra. The needling pathway includes the skin, subcutaneous tissue, latissimus dorsi muscle, intrinsic muscles of the back, quadratus lumborum muscle, the dorsal branches of the second lumbar artery and vein, and the lateral branches containing fibres from the second lumber spinal nerve. Deep perpen...

abstract     in order to study the relationships among seed yield and its components in nigella sativa, path coefficient and factor analysis was done using some agro- morphological traits of 21 different genotypes. genotypes were evaluated using a completely randomized design with four replications in ardestan university research farms. there was a high and positive correlation between seed yie...

BACKGROUND Thoracentesis and video-assisted thoracic surgery procedures can result in haemorrhage as a consequence of severing the collateral branches of the posterior intercostal artery. These branches have been shown to be most common in the 5th intercostal space (ICS). Tortuosity has been shown to be especially prevalent nearer to midline. A group of investigators have recommended the 4th an...

The nerve originates from the L2/L3 segments and travels down, lateral to the psoas muscle. It crosses the iliacus muscle deep to the fascia and then passes through or under the lateral part of the inguinal ligament. It runs superficially and divides into anterior and posterior branches to innervate the lateral thigh. The course of the nerve can be variable. One study of cadaveric specimens fou...
