Microgel-Based 3D Bioprinting: A Convergent Strategy Integrating Material Design, Jamming Dynamics, and Biological Function.

Driven by rapid technological innovation and an increasing demand for personalized medicine, microgel-based bioprinting emerges as a versatile strategy for generating physiologically relevant tissue models and patient-specific constructs. By integrating microgel systems with 3D bioprinting, this approach enables the creation of complex, cell-laden architectures that closely recapitulate native tissue architecture and function. Pivotal to this potential are microgels that offer significant advantages over conventional hydrogel-based bioinks, including tunable rheological behavior, enhanced prin

Harnessing the Therapeutic Potential of Capsaicin and Its Analogues in Pain and Other Diseases.

Capsaicin is the most predominant and naturally occurring alkamide found in Capsicum fruits. Since its discovery in the 19th century, the therapeutic roles of capsaicin have been well characterized. The potential applications of capsaicin range from food flavorings to therapeutics. Indeed, capsaicin and few of its analogues have featured in clinical research covered by more than a thousand patents. Previous records suggest pleiotropic pharmacological activities of capsaicin such as an analgesic, anti-obesity, anti-pruritic, anti-inflammatory, anti-apoptotic, anti-cancer, anti-oxidant, and neur

Role of Ceramide from Glycosphingolipids and Its Metabolites in Immunological and Inflammatory Responses in Humans.

Glycosphingolipids (GSLs) are composed of hydrophobic ceramide and hydrophilic sugar chains. GSLs cluster to form membrane microdomains (lipid rafts) on plasma membranes, along with several kinds of transducer molecules, including Src family kinases and small G proteins. However, GSL-mediated biological functions remain unclear. Lactosylceramide (LacCer, CDw17) is highly expressed on the plasma membranes of human phagocytes and mediates several immunological and inflammatory reactions, including phagocytosis, chemotaxis, and superoxide generation. LacCer forms membrane microdomains with the Sr

A Standardized Method for Vertical Sleeve Gastrectomy Bariatric Surgery Investigations in Cancer.

Obesity is a global epidemic that has affected the lives of over 14% of adults worldwide and over a third of Americans. Obesity is associated with the increased risk of thirteen obesity-associated cancers and poor cancer outcomes. Bariatric surgery is the most effective method of sustained weight loss and has been steadily increasing in clinical use over the past 4 decades. Importantly, bariatric surgery is established to decrease cancer risk. Vertical sleeve gastrectomy (VSG) is currently the most common bariatric surgery procedure. To evaluate underlying mechanisms of bariatric associated ca

Efficacy and safety of C-arm computed tomography-guided microwave ablation with percutaneous osteoplasty for flat bone metastases.

BACKGROUND: Flat bone metastases are common in patients with advanced cancers, often resulting in severe pain, limited mobility, and reduced quality of life (QOL). Traditional treatment options, such as radiotherapy or systemic therapies, often fail to provide sufficient pain relief or improve functional outcomes in these patients. Microwave ablation (MWA) offers advantages, such as shorter procedure times and larger ablation zones, while percutaneous osteoplasty (PO) enhances bone stability and prevents pathological fractures. Despite these benefits, the combination of these techniques for tr

Management of Foot Ulcers and Chronic Wounds with Amniotic Membrane in Comorbid Patients: A Successful Experience.

Chronic wounds are defined as those with disturbances in normal healing. They involve symptoms like exudate, odor, pain or impaired mobility, severely impacting life quality. In the case of patients with additional comorbidities, these are known to aggravate the healing impairment. Amniotic membrane (AM) is gaining attention for its regenerative potential, as it has shown promise in treating hard-to-heal wounds, such as diabetic foot ulcers. This work examines a series of five patients who, while suffering an array of other chronic conditions, were treated with AM for the management of non-hea

Nanoliposomes in Cancer Therapy: Marketed Products and Current Clinical Trials.

The drugs used for cancer treatment have many drawbacks, as they damage both tumor and healthy cells and, in addition, they tend to be poorly soluble drugs. Their transport in nanoparticles can solve these problems as these can release the drug into tumor tissues, as well as improve their solubility, bioavailability, and efficacy, reducing their adverse effects. This article focuses on the advantages that nanotechnology can bring to medicine, with special emphasis on nanoliposomes. For this, a review has been made of the nanoliposomal systems marketed for the treatment of cancer, as well as th

Treatment of bone tumours by radiofrequency thermal ablation.

Radiofrequency thermal ablation (RFTA) is considered the treatment of choice for osteoid osteomas, in which it has long been safely used. Other benign conditions (chondroblastoma, osteoblastoma, giant cell tumour, etc.) can also be treated by this technique, which is less invasive than traditional surgical procedures. RFTA ablation is also an option for the palliation of localized, painful osteolytic metastatic and myeloma lesions. The reduction in pain improves the quality of life of patients with cancer, who often have multiple morbidities and a limited life expectancy. In some cases, these

Терапевтическая способность монометилфумарата и иона алюминия к уменьшению воспаления и окислительного стресса в псориазе.

Псориаз представляет собой хроническое воспалительное состояние кожи, характеризующееся эритематическими досками с белыми чешуями. Его патогенез тесно связан с окислительным стрессом и дисбалансом в иммунной реакции Th1/TH2. Нынешние методы лечения псориаза, такие, как актуальные агенты, системная терапия и фототерапия, часто не достигают полной ремиссии в клинических условиях. Монометилфумарат (MMF), который был утвержден Администрацией США по продуктам питания и наркотикам в 2020 году в отношении множественного склероза, продемонстрировал свою эффективность в борьбе с псориазом. Кроме того,

Cold Atmospheric Plasma in the Treatment of Osteosarcoma.

Human osteosarcoma (OS) is the most common primary malignant bone tumor occurring most commonly in adolescents and young adults. Major improvements in disease-free survival have been achieved by implementing a combination therapy consisting of radical surgical resection of the tumor and systemic multi-agent chemotherapy. However, long-term survival remains poor, so novel targeted therapies to improve outcomes for patients with osteosarcoma remains an area of active research. This includes immunotherapy, photodynamic therapy, or treatment with nanoparticles. Cold atmospheric plasma (CAP), a hig

Regulatory role of PI3K/Akt/WNK1 signal pathway in mouse model of bone cancer pain.

In the advanced stage of cancer, the pain caused by bone metastasis is unbearable, but the mechanism of bone cancer pain (BCP) is very complicated and remains unclear. In this study, we used 4T1 mouse breast cancer cells to establish a bone cancer pain model to study the mechanism of BCP. Then the paw withdrawal mechanical threshold (PWMT) and the hematoxylin-eosin staining were used to reflect the erosion of cancer cells on tibia tissue. We also determined the role of proinflammatory factors (TNF-α, IL-17, etc.) in BCP by the enzyme-linked immunosorbent assay in mouse serum. When GSK690693, a

Schnitzler's Syndrome: A Diagnostic Consideration in Evaluating the Constellation of Monoclonal Gammopathy and Chronic Urticaria.

Schnitzler's syndrome is a rare clinical entity characterized by intermittent, non-pruritic urticarial rash, fevers, arthralgias, myalgias and monoclonal gammopathy, most commonly of the immunoglobulin M (IgM) subtype. Schnitzler's syndrome should be considered in the differential diagnosis of fever of unknown origin. We report a case of a 56-year-old healthy Caucasian female, who initially presented to the primary care physician's office with complaints of severe generalized fatigue and myalgias involving thighs and calves. Patient subsequently underwent extensive rheumatologic workup, and wa

Following the upper lip lacerations were several weeks of intermittent unknown episodic fevers. The patient, challenged by impaired mobility, exhibited an array of symptoms, including severe upper lip pain with lacerations and white patches on the tongue. Laboratory findings indicated thrombocytopenia and anemia, with positive tests for both influenza A and B. Despite completing Tamiflu, the patient expe

Enhancing the Bioavailability of Resveratrol: Combine It, Derivatize It, or Encapsulate It?

Overcoming the limited bioavailability and extensive metabolism of effective in vitro drugs remains a challenge that limits the translation of promising drugs into clinical trials. Resveratrol, despite its well-reported therapeutic benefits, is not metabolically stable and thus has not been utilized as an effective clinical drug. This is because it needs to be consumed in large amounts to overcome the burdens of bioavailability and conversion into less effective metabolites. Herein, we summarize the more relevant approaches to modify resveratrol, aiming to increase its biological and therapeut

Current trends of infectious complications following hematopoietic stem cell transplantation in a single center.

This study was to analyze the infectious complications after hematopoietic stem cell transplantation (HSCT) according to the recent changes of HSCT. Medical records of 379 adult patients who underwent HSCT consecutively at Catholic HSCT Center from January 2001 to December 2002 were reviewed retrospectively. Allogeneic HSCT accounted for 75.7% (287/379) and autologous HSCT for 24.3% (92/379). During pre-engraftment period, bacterial infection was predominant, and E. coli was still the most common organism. After engraftment, viral infection was predominant. The incidence of invasive fungal inf

A case of renal damage induced by cryoglobulinemia associated with Monoclonal Gammopathy of Renal Significance.

BACKGROUND: Cryoglobulins are abnormal immunoglobulins present in circulation, capable of precipitating at lower temperatures and redissolving upon rewarming to body temperature (37 °C). It is widely accepted that mixed cryoglobulinemia is more commonly seen in chronic infections and autoimmune diseases.
