3-D printed, mechanically robust carrier used to deliver immunosuppressive drug, and cells

(Cell Transplantation Center of Excellence for Aging and Brain Repair) After a 3-D printer was used to create a micro but mechanically robust drug and cell carrier for local and sustained delivery of the immunosuppressive drug cyclosporine, researchers demonstrated in tests with animal models that the carrier, a combination of microspheres and hydrogel, maintained robust shape and integrity and delivered a local, sustained release of CsA in an amount that prevented acceleration of cytokines and overcame the need for additional drugs to treat immune rejection.

In this study, a rat DFU model was used to simulate the pathophysiology of clinical patients and to investigate the localization of human umbilical cord mesenchymal stem cells (hUC-MSCs) after intravenous transplantation and its role in DFU healing, so as to evaluate the potential of hUC-MSCs in the treatment of DFU. The diabetic rat model was established by streptozotocin injection, which was used to create full-thickness foot dorsal skin wounds to mimic DFU by a 6-mm skin biopsy punch and a Westcott scissor. The hUC-MSCs were transplanted through femoral vein, and the ulcer cicatrization situation and the fate of hUC-MSC...

Cutting the medial collateral ligament (MCL), even in part, seems counterintuitive. However, medial meniscal surgery is not always easy, and iatrogenic articular cartilage damage can be a complication of partial meniscectomy, meniscus repair, and/or allograft transplantation in a tight knee. Fortunately, partial tears of the MCL tend to heal, and most patients do tolerate iatrogenic, partial MCL tearing without negative long-term sequelae. However, rather than accidentally tearing the MCL during medial meniscal surgery, if you need room to operate, partially release the MCL.

Intraoperative transesophageal echocardiography is a standard diagnostic and monitoring tool employed in the management of patients undergoing an entire spectrum of cardiac surgical procedures, ranging from “routine” surgical coronary revascularization to complex valve repair, combined procedures, and organ transplantation. Utilizing a protocol as a starting point for imaging in all procedures and all patients enables standardization of image acquisition, reduction in variability in quality of imag ing and reporting, and ultimately better patient care.

Abstract The lacrimal glands produce the aqueous component of the pre-ocular tear film, which is essential for ocular health and optimal vision. This review explores its history, current understanding and recent advances, and scope for future research. It traces the evolution of human knowledge about the source of tears across several millennia, with specific emphasis on the individuals who made seminal contributions to this field. It provides a detailed update on the morphology, microscopic structure, innervation, vascular supply, and imaging modalities of both the main and accessory lacrimal glands. The review a...

Conclusions. Chronic airway injury and dysregulated repair programs are evident in airway epithelium obtained from patients with BOS, particularly with SAEC. We also show that azithromycin partially mitigates this pathology.

Abstract Multiple disease-modifying medications with regulatory approval to treat multiple sclerosis (MS) are unable to prevent inflammatory tissue damage in the central nervous system (CNS), and none directly promote repair. Thus, there is an unmet clinical need for therapies that can arrest and reverse the persistent accumulation of disabilities associated with progressive forms of MS (P-MS). Preclinical research has revealed an unexpected ability of neural stem cell (NSC) therapies to provide neurotrophic support and inhibit detrimental host immune responses in vivo following transplantation into the chronicall...

A new study shows that when specific human brain cells are transplanted into animal models of multiple sclerosis and other white matter diseases, the cells repair damage and restore function. The study provides one of the final pieces of scientific evidence necessary to advance this treatment strategy to clinical trials.
