Cigarette smoking negatively impacts mesenchymal stem cell functionality, including proliferation, viability, and differentiation potential. Adipose-derived mesenchymal stem cells (ADMSCs) are increasingly used for therapeutic purposes, but the specific effects of smoking in vivo on these cells are poorly understood. This study investigates the effects of cigarette smoke on the proliferation, viability, gene expression, and cellular functions of ADMSCs from smoking and non-smoking donors.

Females were aged ≤ 35 years, had at least two consecutive first-trimester RPLs, and the acquired cause of RPL was excluded.

It is likely to be an autoimmune in origin, presenting persistent therapeutic challenges despite current therapies. This study aims to investigate the potential of umbilical cord mesenchymal stromal cells (UCMSCs) in treating ulcerative colitis (UC).

Design: Multi-institutional cross-sectional study.
Participants: Patients ≥ 65 years of age who underwent cataract surgery at Johns Hopkins Hospital (JHH) and Kaiser Permanente (KP) between January 1, 2017, and December 31, 2019.
Background: Recently we reported results of phase 1 pilot clinical trial of 2 consecutive intracavernous (IC) injection of autologous bone marrow-derived mesenchymal stem cells (BM-MSCs) for the first time in the treatment of diabetic patients with erectile dysfunction (DM-ED). In phase 2 of this study our aim is to evaluate long term safety and efficacy of IC injections of BM-MSC on additional eight patients with DM-ED.
Results: Each patient received 2 consecutive IC injections of BM-MSC and evaluated at 1, 3, 6, 12, and 24-month time points.
Introduction: Von Hippel-Lindau disease (e.g. VHL) is an autosomal dominant multi-organ cancer syndrome caused by a mutation in the tumour suppressor gene.

Presently, treatment modalities for chronic SCI have restricted clinical effectiveness. Mesenchymal stromal cells (MSCs) demonstrate promise in addressing nervous tissue damage.

Patient And Methods: A retrospective chart review of all patients with eyelid lacerations presenting to the ED at a single level 1 trauma center was performed. Eyelid lacerations were categorized as simple eyelid lacerations, eyelid lacerations with eyelid margin involvement, and eyelid lacerations with nasolacrimal system involvement.
Multiple sclerosis (MS) is a chronic neuro-inflammatory disease resulting in disabilities that negatively impact patients' life quality. While current treatment options do not reverse the course of the disease, treatment using mesenchymal stromal/stem cells (MSC) is promising. There has yet to be a consensus on the type and dose of MSC to be used in MS.

They manifest as dysplasia in bone marrow hemopoietic elements associated with peripheral cytopenias with variable risk of AML transformation.
Patients And Methods: We analyzed retrospectively registry data collected prospectively from patients with primary MDS and patients with MDS/myeloproliferative neoplasm (MPN) in the Jordan University Hospital between January 2007 and September 2021.
Purpose: To determine current prescribing patterns for topical or intraocular/periocular anti-inflammatory medications (AIMs) after routine cataract surgery.
Setting: kera-net online members.
Design: Cross-sectional survey.
Purpose: To assess the refractive accuracy of eight intraocular lens (IOL) formulas in eyes that underwent combined phacovitrectomy.
Methods: A retrospective chart review of 59 eyes that underwent uncomplicated phacovitrectomy between 2017 and 2020 at the Johns Hopkins Wilmer Eye Institute. Inclusion criteria were postoperative best corrected visual acuity of 20/40 or better within 6 months of surgery and IOL implantation in the capsular bag.
The corneal epithelial layer is continuously replaced by limbal stem cells. Reconstructing this layer in vitro using synthetic scaffolds is highly needed. Poly-lactic-co-glycolic acid (PLGA) is approved for human use due to its biocompatibility and biodegradability.

To better understand resistance mechanisms and identify novel therapies, robust preclinical models mimicking the bone marrow (BM) microenvironment are needed. This study aimed to achieve an automated fabrication process of a three-dimensional (3D) AML disease model that recapitulates the 3D spatial structure of the BM microenvironment and applies to drug screening and investigational studies.

Methods: A task force involving key opinion leaders, experts in the management of breast cancer, and stakeholders in healthcare systems where genetic testing is available in Jordan discussed current evidence and local real-life practice. The task force then formulated recommendations to achieve better patient outcomes and satisfaction based on evidence-based medicine and their clinical experience in BRCA-mutated breast cancer management.
Gold nanoparticles (AuNPs) are one of the most stable nanoparticles that have been prevalently used as examples for biological and biomedical applications. Herein, we evaluate the effect of AuNPs on the biological processes of dental pulp stem cells derived from exfoliated deciduous teeth (SHED). Two different shapes of PEGylated AuNPs, rods (AuNR-PEG) and spheres (AuNS-PEG), were prepared and characterized.

Here, we demonstrate that the small GTPase Ran has predictive value for breast cancer (BC) patients as a whole, and for specific BC subtypes.
Patients And Methods: Ran expression was quantified by immunohistochemistry in 263 patients with primary breast cancer diagnosed at the Breast Unit, Royal Liverpool Hospital.
Purpose: To identify factors related to suboptimal refractive outcomes after toric intraocular lens implantation.
Patients And Methods: A retrospective case-control chart review of 446 eyes with toric lens insertion by the same surgeon at a university hospital from 2016 to 2020 was conducted. Pre-operative exam findings, biometry, and one month and three month post-operative vision and refraction were noted.
Diabetes Mellitus Type 1 is an autoimmune disease that occurs due to the destruction of insulin-producing cells (β cells), resulting in hyperglycemia. Therefore, diabetic patients depend on insulin treatment for the rest of their lives. Stem cells are considered a promising cellular therapy to replace the nonfunctional beta cells with functional and mature beta cells.

Nonetheless, in most cases, the resulting disability permanently affects the individual's quality of life due to the limited outcome of available treatment options. The neurological deficit associated with SCI results from primary injury induced by the physical trauma and secondary injury involving inflammation, spinal tissue degeneration, and scar formation.
