Injectable PLGA Microscaffolds with Laser-Induced Enhanced Microporosity for Nucleus Pulposus Cell Delivery.

Intervertebral disc (IVD) degeneration is a leading cause of lower back pain (LBP). Current treatments primarily address symptoms without halting the degenerative process. Cell transplantation offers a promising approach for early-stage IVD degeneration, but challenges such as cell viability, retention, and harsh host environments limit its efficacy.

Treatments and clinical outcomes in stage II colon cancer patients with 12-gene Oncotype DX Colon Recurrence Score® assay-guided therapy: real-world data.

Background: The 12-gene Oncotype DX Colon Recurrence Score® result quantifies the recurrence risk in stage II/III colon cancer (CC). This real-world study investigated stage II CC patients whose treatment decisions incorporated the Recurrence Score® (RS) result.

Materials And Methods: This retrospective analysis of a prospectively designed cohort included all stage II, mismatch repair-proficient CC patients who underwent 12-gene testing through Clalit between January 2011 and December 2016 and had available data with a minimum 3-year follow-up.

Altered Serum Alpha1-Antitrypsin Protease Inhibition before and after Clinical Hematopoietic Stem Cell Transplantation: Association with Risk for Non-Relapse Mortality.

α1-Antitrypsin (AAT), an acute-phase reactant not unsimilar to C-reactive protein (CRP), is a serine protease inhibitor that harbors tissue-protective and immunomodulatory attributes. Its concentrations appropriately increase during conditions of extensive tissue injury, and it induces immune tolerance, in part, by inhibiting the enzymatic activity of the inflammatory serine protease, proteinase 3 (PR3). Typically administered to patients with genetic AAT deficiency, AAT treatment was recently shown to improve outcomes in patients with steroid-refractory graft-versus-host disease (GVHD).

Innate Immunity and CKD: Is There a Significant Association?

Chronic kidney disease (CKD) constitutes a worldwide epidemic, affecting approximately 10% of the global population, and imposes significant medical, psychological, and financial burdens on society. Individuals with CKD often face elevated morbidity and mortality rates, mainly due to premature cardiovascular events. Chronic inflammation has been shown to play a significant role in the progression of CKD, as well as in the acceleration of CKD-related complications, including atherosclerosis, cardiovascular disease (CVD), protein-energy wasting, and the aging process.

Intervertebral disc human nucleus pulposus cells associated with back pain trigger neurite outgrowth in vitro and pain behaviors in rats.

Low back pain (LBP) is often associated with the degeneration of human intervertebral discs (IVDs). However, the pain-inducing mechanism in degenerating discs remains to be elucidated. Here, we identified a subtype of locally residing human nucleus pulposus cells (NPCs), generated by certain conditions in degenerating discs, that was associated with the onset of discogenic back pain.

Role of clinicopathological variables in predicting recurrence and survival outcomes after surgery for non-metastatic renal cell carcinoma: Systematic review and meta-analysis.

Renal cell carcinoma (RCC) represents 2% of all diagnosed malignancies worldwide, with disease recurrence affecting 20% to 40% of patients. Existing prognostic recurrence models based on clinicopathological features continue to be a subject of controversy. In this meta-analysis, we summarized research findings that explored the correlation between clinicopathological characteristics and post-surgery survival outcomes in non-metastatic RCC patients.

Predicting clinical outcome of sulfur mustard induced ocular injury using machine learning model.

The sight-threatening sulfur mustard (SM) induced ocular injury presents specific symptoms in each clinical stage. The acute injury develops in all exposed eyes and may heal or deteriorate into chronic late pathology. Early detection of eyes at risk of developing late pathology may assist in providing unique monitoring and specific treatments only to relevant cases.

Influence of residency discipline and seniority on traumatic musculoskeletal radiographs interpretation accuracy: a multicenter study.

Objectives: Imaging studies are a significant and integral part of the initial assessment of patients admitted to the emergency department. Developing imaging diagnostic abilities early in residency is of paramount importance. The purpose of this study was to evaluate and compare diagnosis accuracy of common musculoskeletal X-rays (XR) between residency disciplines and seniority.

Revealing leukocyte populations in human peri-implantitis and periodontitis using flow cytometry.

Objective: To identify, quantify, and characterize leukocyte populations in PI and periodontitis using flow cytometry.

Methods: Fresh biopsies from human PI and periodontitis lesions were processed to a single-cell suspension. The immune cell types were identified using flow cytometry.

[FALSE POSITIVE 5-ALA INDUCED FLUORESCENCE OF HEMATOLOGICAL MALIGNANCIES, BENIGN TUMORS, INFECTIOUS AND INFLAMMATORY PATHOLOGIES PRESENTED AS BRAIN LESIONS - A CASE SERIES].

The 5-aminolevulinic acid (5-ALA) fluorescence-guided resection is an essential part of the current state-of-the-art treatment of primary malignant brain tumors. Metabolized by tumor cells, creating Protoporphyrin-IX, which is fluorescent under UV light emitted from the microscope, 5-ALA facilitates visual distinction between the tumor and the normal brain tissue surrounding it, coloring it pink. This real-time diagnostic feature was shown to lead to more complete removal of the tumor and confers a survival benefit.

Mathematical models of learning and what can be learned from them.

Learning is a multi-faceted phenomenon of critical importance and hence attracted a great deal of research, both experimental and theoretical. In this review, we will consider some of the paradigmatic examples of learning and discuss the common themes in theoretical learning research, such as levels of modeling and their corresponding relation to experimental observations and mathematical ideas common to different types of learning.

Palatal soft tissue thickness around dental implants and natural teeth in health and disease: A cross sectional study.

Background: Previous studies focused on the influence of buccal mucosa thickness on peri-implant bone loss and inflammation, with inconclusive results. We observed substantially thicker palatal mucosal tissues at peri-implantitis sites. Therefore, we hypothesize that thick palatal peri-implant mucosa may be associated with deeper pockets and disease severity.

Digital photometric analysis of gingival response to periodontal treatment.

Objectives: The color is a major factor in determining inflammation status in most gingival indices. Current indices have limitations mainly due to subjective nature. Digital color analysis can provide objective and accurate measurements.

Vascular Graft Infection Imaging.

Vascular graft infection is a rare, life threatening complication of vascular repair with synthetic or native material. The pathogenesis, causative microorganisms and clinical manifestations vary according to graft's location and time duration since surgery. The diagnosis of graft infection is challenging since there is no single "gold standard" test and diagnosis is based on clinical and radiological criteria.

[GESTATIONAL TROPHOBLASTIC DISEASE: THE NEED FOR CENTRALIZATION OF TREATMENT CENTERS IN ISRAEL].

Gestational trophoblastic disease comprises a spectrum of pregnancy-related disorders, consists of premalignant disorders of complete and partial hydatidiform mole, and malignant disorders such as invasive mole, choriocarcinoma, and the rare placental-site trophoblastic tumor/epithelioid trophoblastic tumor. These malignant forms are termed Gestational Trophoblastic Neoplasia (GTN). Until the early 1960's, hysterectomy was the treatment of choice for women with malignant trophoblastic diseases.

Information Theory Solution Approach to the Air Pollution Sensor Location-Allocation Problem.

Air pollution is one of the prime adverse environmental outcomes of urbanization and industrialization. The first step toward air pollution mitigation is monitoring and identifying its source(s). The deployment of a sensor array always involves a tradeoff between cost and performance.

LGR5 expressing skin fibroblasts define a major cellular hub perturbed in scleroderma.

Systemic sclerosis (scleroderma, SSc) is an incurable autoimmune disease with high morbidity and mortality rates. Here, we conducted a population-scale single-cell genomic analysis of skin and blood samples of 56 healthy controls and 97 SSc patients at different stages of the disease. We found immune compartment dysfunction only in a specific subtype of diffuse SSc patients but global dysregulation of the stromal compartment, particularly in a previously undefined subset of LGR5-scleroderma-associated fibroblasts (ScAFs).
