Progressive aniridia associated keratopathy is worsening visual acuity of congenital aniridia subjects lifelong. Restoration of PAX6 expression in PAX6 haploinsufficient limbal epithelial cells could be one therapeutic option. In a previous study using aniridia-like CRISPR/Cas9 genome-edited corneal epithelial cells, the antipsychotic drugs duloxetine and ritanserin increased PAX6 mRNA and protein expression.

Aortic regurgitation is a common valve disease and can be caused by delineated findings such as fenestrations or hardly discernible alterations of the aortic root geometry. Therefore, aortic regurgitation can be a challenging diagnosis during an autopsy. Cardiac surgeons, however, are confronted with comparable problems during surgery and have developed a refined knowledge of the anatomy of the aortic root including its geometry.

Background: Although to date the pathogenesis of endometriosis remains largely unexplained, it is known that processes of migration, proliferation and revascularization and thus calcium as a messenger substance play an important role. Consecutively, the present study examines the immunohistochemical expression of the calcium transient receptor potential channels 3 and 6 (TRPC3 and TRPC6) in ectopically located (outside the uterine cavity) endometrial tissue.

Methods: Laparoscopically collected and histomorphologically verified endometriosis tissues from several different intraabdominal locations were examined (n = 20) and immunohistochemical stainings were performed with anti-TRPC3 and anti-TRPC6 antibodies (Alomone Labs, Jerusalem).

Background: Canonical transient receptor potential channels play a crucial role in cancer cell proliferation. While TRPC6 subtype detection in submandibular glands and the relevance of some TRPC channels in this gland have been shown in animal models, its histological detection in human lacrimal and submandibular glands, as well as related tumors, lacks systematic study. Studying TRPC6 in humans could lead to new therapeutic options.

During routine dissections of cadavers as part of the medical curriculum, we identified a rare unilateral variation in the brachial plexus on the right side of a female body donor. This variation consisted of four unusual changes to the regular pattering of nerve bundles and the dorsal scapular artery permeating the complex neural network. The variation included contributions of root C4 to the plexus by a root C4/C5 anastomosis, a rare fusion of the superior and middle trunks to a 'superomiddle' trunk, a preliminary, proximal branching of the suprascapular nerve off the C5 root.

  • The study compares the peak insertion torques of three types of screws used for cervical spine fixation: lateral mass screws (LMS), pedicle screws, and the new Attallah screw.
  • Results indicate that while the Attallah screw has comparable torque to pedicle screws at certain cervical levels, it generally shows lower strength at C5 and C6.
  • Overall, the findings suggest that the Attallah screw is a viable option for posterior cervical fixation, but pedicle screws are still considered superior in strength, especially between C5 and C6.
