Lumbar Pedicle Morphology and Vertebral Dimensions in Isthmic and Degenerative Spondylolisthesis-A Comparative Study.

Background: The pedicle screw is the most common device used to achieve fixation in fusion of spondylolistheses. Safe and accurate placement with this technique relies on a thorough understanding of the bony anatomy. There is a paucity of literature comparing the surgically relevant osseous anatomy in patients with a degenerative spondylolisthesis (DS) and an isthmic spondylolisthesis (IS).

The space of man's death. A modern age secondary burial case in northern Italy.

Much of the recent archaeological and anthropological research on Italian modern age secondary burials has focused primarily on source analysis and the funerary context descriptions. To enable a clearer understanding of these atypical burials we need more archaeological data. To comprehend the mortuary practices it is necessary to investigate the surviving funeral monuments, burials and human remains.

A case of erosive polyarthropathy from Medieval northern Italy (12th-13th centuries).

Objective: To evaluate and differentially diagnose erosive skeletal lesions located on multiple joints of an individual archaeologically recovered in 2017.

Materials: Skeletal remains of a well-preserved skeleton dating to the 12th-13th centuries from the medieval church of San Biagio in Cittiglio (Varese, northern Italy).

Methods: Macroscopic and radiographic imaging.

Platelet-Rich Plasma Injection With Percutaneous Needling for Recalcitrant Lateral Epicondylitis: Comparison of Tenotomy and Fenestration Techniques.

Background: Recalcitrant lateral epicondylitis (LE) is a common debilitating condition, with numerous treatment options of varying success. An injection of platelet-rich plasma (PRP) has been shown to improve LE, although it is unclear whether the method of needling used in conjunction with a PRP injection is of clinical importance.

Purpose: To determine whether percutaneous needle tenotomy is superior to percutaneous needle fenestration when each is combined with a PRP injection for the treatment of recalcitrant LE.

Epigenetic variation, inheritance, and parent-of-origin effects of cytosine methylation in maize (Zea mays).

Pure epigenetic variation, or epigenetic variation that is independent of genetic context, may provide a mechanism for phenotypic variation in the absence of DNA mutations. To estimate the extent of pure epigenetic variation within and across generations and to identify the DNA regions targeted, a group of eight plants derived from a highly inbred line of maize (Zea mays) was analyzed by the methylation-sensitive amplified polymorphism (MSAP) technique. We found that cytosine methylation (mC) differences among individuals accounted for up to 7.
