Identification of new candidate biomarkers to support doxorubicin treatments in canine cancer patients.

BackgroundBoth human and veterinary cancer chemotherapy are undergoing a paradigm shift from a "one size fits all" approach to more personalized, patient-oriented treatment strategies. Personalized chemotherapy is dependent on the identification and validation of biomarkers that can predict treatment outcome and/or risk of toxicity. Many cytotoxic chemotherapy agents, including doxorubicin, base their mechanism of action by interaction with DNA and disruption of normal cellular processes. We developed a high-resolution/accurate-mass liquid chromatography-mass spectrometry DNA screening approac

Колониальная ишемия без мезентерического оккулирования: случай, имплицитирующий интерферон-β.

Интерфероны типа I являются широко используемыми иммунодуляторными агентами. Интерферон-α (интерферон-α) связан с ишемическим колитом, но случаи, связывающие интерферон-β (IFN-β) с ишемическим колитом, редки.

The Crystalline Nephropathies.

Crystalline nephropathies are a unique form of kidney disease characterized by the histologic finding of intrarenal crystal deposition. The intrinsic nature of some molecules and ions combined with a favorable tubular fluid physiology leads to crystal precipitation and deposition within the tubular lumens. Crystal deposition promotes kidney injury through tubular obstruction and both direct and indirect cytotoxicities. Further kidney injury develops from inflammation triggered by these crystals. From a clinical standpoint, the crystalline nephropathies are associated with abnormal urinalysis a

NK3.3-Derived Extracellular Vesicles Penetrate and Selectively Kill Treatment-Resistant Tumor Cells.

Cancer treatments often become ineffective due to the development of tumor resistance, leading to metastasis and relapse. Treatments may also fail because of their inability to access cells deep within the tumor tissue. When this occurs, new therapeutic agents are needed. We previously reported that NK3.3EVs, extracellular vesicles (EVs) derived from the normal human natural killer (NK) cell line, NK3.3, have strong cytotoxic activity against leukemia and breast cancer cell lines, without harming normal cells. Here, we used a three-dimensional (3D) MCF7 breast cancer mammosphere model to repro

A modified method for reducing renal injury in zoledronic Acid treatment of hypercalcemia and adverse skeletal events.

AimsIn this paper, we have reported a previously undescribed risk factor of deterioration of renal function in zoledronic acid treatment of skeletal metastasis - high serum calcium level. Based on this consideration, a modified method of treatment of hypercalcemia (HCM) with zoledronic acid is suggested in this paper.Material and methodsBone scan findings of 1090 cancer patients were analyzed, of which 26 had intense renal parenchymal uptake as a result of HCM or bone metastases. Subsequently, a total of 56 bone metastases patients with zoledronic acid treatment were divided into three groups:

Macrophage Activation Markers, CD163 and CD206, in Acute-on-Chronic Liver Failure.

Macrophages facilitate essential homeostatic functions e.g., endocytosis, phagocytosis, and signaling during inflammation, and express a variety of scavenger receptors including CD163 and CD206, which are upregulated in response to inflammation. In healthy individuals, soluble forms of CD163 and CD206 are constitutively shed from macrophages, however, during inflammation pathogen- and damage-associated stimuli induce this shedding. Activation of resident liver macrophages viz. Kupffer cells is part of the inflammatory cascade occurring in acute and chronic liver diseases. We here review the ex

Pathophysiology and Treatments of Complications of Waldenström's Macroglobulinemia.

Waldenstrom's macroglobulinemia (WM) or lymphoplasmacytic lymphoma is a B-cell malignancy characterized by lymphoplasmacytic cells in the bone marrow that secrete high amounts of immunoglobulin (Ig) M. The large pentameric structure of IgM leads to a variety of unique complications in WM, such as hyperviscosity syndrome, cryoglobulinemia and sensory neuropathy. Furthermore, malignant cells can infiltrate the central nervous system and lead to a variety of neurological complications, also known as Bing Neel Syndrome. Because of the unique pathophysiology of WM and these complications, their dia

Role of TLR2 rs5743708 and dectin-1 rs16910526 polymorphisms in susceptibility to fungal infections in COVID-19 patients.

IntroductionThe progression of fungal co-infection with COVID-19 depends on the patient's genetic innate immunity. Our goal is to understand the connection between the single nucleotide polymorphisms (SNPs) rs5743708 and rs16910526 in the toll-like receptor 2 (TLR2) and dectin-1 (CLEC7A) genes, respectively, and fungal infection in COVID-19 patients.Material and methodsThis study assessed the SNPs rs5743708 from the TLR2 gene and rs16910526 from dectin-1 by Sanger sequencing. Two groups of COVID-19 patients participated in this study: 110 COVID-19 patients free from fungal infection (COVID-19

Multiple myelomas in cats.

Multiple myelomas are uncommon neoplasms of the bone marrow of cats [Weber NA, Tebeau CS (1998) An unusual presentation of multiple myeloma in two cats. Journal of the American Animal Hospital Association34 (6), 477-483]. Nine cats diagnosed with multiple myelomas were retrospectively identified over a 16-year period (1986-2002). Cats with multiple myelomas were older than 7 years (mean age 11.7 years); six males and three females were affected (2.1), but no breed predisposition was evident. Treatment of multiple myelomas consisted of supportive management in the nine cats and anti-neoplastic

Prevalence, putative mechanisms, and current management of sleep problems during chemotherapy for cancer.

Sleep problems are highly prevalent in cancer patients undergoing chemotherapy. This article reviews existing evidence on etiology, associated symptoms, and management of sleep problems associated with chemotherapy treatment during cancer. It also discusses limitations and methodological issues of current research. The existing literature suggests that subjectively and objectively measured sleep problems are the highest during the chemotherapy phase of cancer treatments. A possibly involved mechanism reviewed here includes the rise in the circulating proinflammatory cytokines and the associate

… This model suggests that sleep problems occur as a result of predisposing and precipitating factors and may become chronic as a result of perpetuating factors (see Figure 1 ). … Thus, this model posits that sleep problems might be maintained via perpetuating factors even when the original stressor (precipitating factor) is no longer present. …

Clinical relevance of extracellular vesicles in hematological neoplasms: from liquid biopsy to cell biopsy.

In the era of precision medicine, liquid biopsy is becoming increasingly important in oncology. It consists in the isolation and analysis of tumor-derived biomarkers, including extracellular vesicles (EVs), in body fluids. EVs are lipid bilayer-enclosed particles, heterogeneous in size and molecular composition, released from both normal and neoplastic cells. In tumor context, EVs are valuable carriers of cancer information; in fact, their amount, phenotype and molecular cargo, including proteins, lipids, metabolites and nucleic acids, mirror nature and origin of parental cells rendering EVs a

Cryoglobulinemia Type II: Sustained Remission After B-Cell-Directed Therapy.

BACKGROUND Cryoglobulinemia is a rare disease with a prevalence of <5 cases per 10 000. In many cases there is significant diagnostic delay, leading to years of morbidity. There are no randomized trials on non-infectious type II cryoglobulinemia, and choice of therapy is based on clinical expertise and observational data. Therapy based on the monoclonal anti-CD20 antibody rituximab in combination with glucocorticosteroids is the preferred choice in many centers. This strategy induces clinical remission in two-thirds of patients. However, one-third of the initially-responding patients experienc

Clinical review: specific aspects of acute renal failure in cancer patients.

Acute renal failure (ARF) in cancer patients is a dreadful complication that causes substantial morbidity and mortality. Moreover, ARF may preclude optimal cancer treatment by requiring a decrease in chemotherapy dosage or by contraindicating potentially curative treatment. The pathways leading to ARF in cancer patients are common to the development of ARF in other conditions. However, ARF may also develop due to etiologies arising from cancer treatment, such as nephrotoxic chemotherapy agents or the disease itself, including post-renal obstruction, compression or infiltration, and metabolic o
