Effect of Donor Site Selection for Fat Grafting on the Yield and Viability of the Stromal Vascular Fraction.

Background: The efficacy of stromal vascular fraction (SVF) treatment, or stem cell treatment, directly depends on the SVF cell count and the cells' viability. The SVF cell count and viability are in direct correlation with the adipose tissue harvesting site that yields SVF cells, making this research a contribution to developing tissue guidance.

Objectives: The aim of this study was to investigate the importance of harvesting subcutaneous adipose tissue-derived SVF cells on the concentration and viability of SVF.

The diagnostic dilemma of a gallbladder volvulus: An unusual case report and review of the literature.

Introduction And Importance: A gallbladder volvulus is a rare medical condition requiring emergency surgery. There are 500 cases reported in the literature, and only 10 % have ever been diagnosed preoperatively. Gallbladder volvulus occurs when the gallbladder torts around the cystic duct and cystic artery resulting in occlusion of both structures and consequently, ischemia of the gallbladder.

"We regret to inform you that you did not match": Reflections on how to improve the match experience.

There is increasing concern amongst stakeholders over the high numbers of unmatched Canadian Medical Graduates (CMGs), yet little is known from the perspective of those who go unmatched. We present an opinion-based narrative analysis examining the matching process by reflecting on the pre- and post-match period and provide suggestions related to the Canadian context from the unmatched perspective. The challenge in the pre-match period was a lack of transparency around elective availability, resident selection criteria, and what happens after going unmatched.

Cholinergic Modulation of Frontoparietal Cortical Network Dynamics Supporting Supramodal Attention.

A critical function of attention is to support a state of readiness to enhance stimulus detection, independent of stimulus modality. The nucleus basalis magnocellularis (NBM) is the major source of the neurochemical acetylcholine (ACh) for frontoparietal cortical networks thought to support attention. We examined a potential supramodal role of ACh in a frontoparietal cortical attentional network supporting target detection.

The expression and significance of p53 protein and Ki-67 protein in pterygium.

Background/aim: Pterygium is considered to be a degenerative disease of the conjunctiva, however, the presence of tumor markers in pterygium reinforces the hypothesis that this lesion is similar to tumor. Inactivation of p53 function removes an obstacle to increased proliferation. Factors affecting the prevalence of p53 expression in pterygium deserve investigation.
