Одинокий квантовый Sodium MRI на 3T для разделения сигналов Sodium и Mono и B-T2.

Из-за десятикратной разницы в концентрации натрия на мембранах, которая активно поддерживается насосом с натрием-потассием (Na+-K+), клеточный ионный баланс очень чувствительн. Разрывы в этом насосе или мембранной целостности, наблюдаемые в таких неврологических расстройствах, как эпилепсия, множественный склероз, биполярное заболевание и легкая травма головного мозга, приводят к увеличению внутриклеточного натрия. Однако это изменение клеточного уровня часто маскируется доминирующим внеклеточным сигналом натрия, что затрудняет проведение различия между популяциями натрия с моно- и биэкспонент

Лечение болезни костей миэломы: Когда, как часто и как долго?

Площадь ММ в последние годы резко изменилась. Было введено несколько новых и более эффективных методов лечения, которые не только делают пациентов более продолжительными, но и приводят их к более глубокой ремиссии. Это делает потенциальное общее воздействие защитной обработки костей гораздо более высоким, но, возможно, и менее необходимым. Введены новые и более точные методы воображения, которые делают обнаружение костных заболеваний более чувствительным, и введение критериев SLIM-CRAB изменило параметры, использовавшиеся в старых клинических испытаниях для исследования лечения костных заболев

Application of Nanoparticles for Magnetic Hyperthermia for Cancer Treatment-The Current State of Knowledge.

Hyperthermia (HT) is an anti-cancer therapy commonly used with radio and chemotherapies based on applying heat (39-45 °C) to inhibit tumor growth. However, controlling heat towards tumors and not normal tissues is challenging. Therefore, nanoparticles (NPs) are used in HT to apply heat only to tumor tissues to induce DNA damage and the expression of heat shock proteins, which eventually result in apoptosis. The aim of this review article is to summarize recent advancements in HT with the use of magnetic NPs to locally increase temperature and promote cell death. In addition, the recent develop

Significance of long chain polyunsaturated fatty acids in human health.

In the last decades, the development of new technologies applied to lipidomics has revitalized the analysis of lipid profile alterations and the understanding of the underlying molecular mechanisms of lipid metabolism, together with their involvement in the occurrence of human disease. Of particular interest is the study of omega-3 and omega-6 long chain polyunsaturated fatty acids (LC-PUFAs), notably EPA (eicosapentaenoic acid, 20:5n-3), DHA (docosahexaenoic acid, 22:6n-3), and ARA (arachidonic acid, 20:4n-6), and their transformation into bioactive lipid mediators. In this sense, new familie

Effects of glucocorticoid replacement therapy in patients with pituitary disease: A new perspective for personalized replacement therapy.

Secondary adrenal insufficiency (SAI) is an endocrine disorder due to impaired secretion of ACTH resulting from any disease affecting the pituitary gland. Glucocorticoid replacement therapy is mandatory to ensure patient survival, haemodynamic stability, and quality of life. In fact, a correct dose adjustement is mandatory due to the fact that inappropriately low doses expose patients to hypoadrenal crisis, while inappropriately high doses contribute to glucose metabolic and cardiovascular deterioration. This review analyses the current evidence from available publications on the epidemiology

EHA Guidelines on Management of Antithrombotic Treatments in Thrombocytopenic Patients With Cancer.

In cancer patients, thrombocytopenia can result from bone marrow infiltration or from anticancer medications and represents an important limitation for the use of antithrombotic treatments, including anticoagulant, antiplatelet, and fibrinolytic agents. These drugs are often required for prevention or treatment of cancer-associated thrombosis or for cardioembolic prevention in atrial fibrillation in an increasingly older cancer population. Data indicate that cancer remains an independent risk factor for thrombosis even in case of thrombocytopenia, since mild-to-moderate thrombocytopenia does n

Улучшается прогноз по множественным болезням кости миэломы: анализ ретроспективного анализа хирургических операций.

Множественная миелома (ММ) — гематологическая порча, характеризующаяся инфильтрацией костного мозга и формированием остеолитической опухоли. Несмотря на успехи в лечении этого заболевания, ММ остается неизлечимым и часто приводит к осложнениям, таким, как множественные заболевания костей миэломы (ММБД). Для борьбы с симптомами, связанными с болезнью костей, включая боль и переломы, часто необходимо хирургическое вмешательство. 135 у пациентов с диагнозом MMBD, которые прошли операцию, по сравнению с 190 у пациентов с диагнозом MM, которые не прошли хирургическую операцию и служили в качестве к

Development and validation of a novel modified cancer cachexia index in patients with locally advanced gastric cancer undergoing neoadjuvant chemotherapy: a multicenter cohort study.

BACKGROUND: Although the cachexia index (CXI) is a well-established prognostic predictor in gastric cancer (GC) patients, its effectiveness in patients with locally advanced gastric cancer (LAGC) who have undergone neoadjuvant chemotherapy (NACT) remains unclear. METHODS: This multicenter study included 600 LAGC patients treated with NACT from January 2010 to June 2022. A modified CXI was constructed based on Random Forest model, calculated as (post-NACT subcutaneous adipose tissue area at L3) × (post-NACT serum albumin)/(post-NACT platelet count) . Patients were categorized into mCXI-low and

A population-based study of the clinical course of chronic fatigue syndrome.

BackgroundChronic fatigue syndrome (CFS) presents a challenge for patients, health care providers, and health insurance groups because of its incapacitating nature, unknown cause, and poorly understood prognosis. We conducted a longitudinal population-based study to characterize the clinical course of CFS.MethodsSixty-five CFS subjects were identified from a random-digit-dialing survey of Wichita, Kansas residents and followed for up to 3 years. We evaluated changes in CFS classification (partial or total remission, alternative medical or psychiatric diagnoses), CFS case-defining criteria, wel

Cancer and the kidney: dangereoux liasons or price paid for the progress in medicine?

A long time ago, the links between renal disease and malignancy were observed, however, quite recently, their importance was recognized and 'new' subspecialty in nephrology, namely 'onconephrology' was established. In the XXI century, patients with malignancy make up the most growing number of the subjects seen for nephrology consult and/or critical care nephrology services. A plethora of renal problems may be found in patients with malignancy. They may influence not only their short-term outcomes but also the adequate therapy of the underlying oncological problem. Thus, all these kidney-relat

A machine learning model for identifying patients at risk for wild-type transthyretin amyloid cardiomyopathy.

Transthyretin amyloid cardiomyopathy, an often unrecognized cause of heart failure, is now treatable with a transthyretin stabilizer. It is therefore important to identify at-risk patients who can undergo targeted testing for earlier diagnosis and treatment, prior to the development of irreversible heart failure. Here we show that a random forest machine learning model can identify potential wild-type transthyretin amyloid cardiomyopathy using medical claims data. We derive a machine learning model in 1071 cases and 1071 non-amyloid heart failure controls and validate the model in three nation

A novel alkaloid compound, DCZ0358, exerts significant antitumor activity in bortezomib-resistant multiple myeloma cells through inhibition of JAK2/STAT3 pathway.

Multiple myeloma (MM), the second most common haematological malignancy, is currently incurable because patients often develop multiple drug resistance and experience subsequent relapse of the disease. This study aims to identify a potential therapeutic agent that can counter bortezomib (BTZ) resistance in MM. DCZ0358, a novel alkaloid compound, is found to exert potent cytotoxic effects against BTZ-resistant MM cells in vivo and in vitro. The anti-myeloma activity of DCZ0358 is associated with inhibition of cell proliferation, promotion of cell apoptosis via caspase-mediated apoptotic pathway

Оптимизация доставки каннабидиол: повышение растворимости и проницаемости воды посредством фосфолипидной комплексации.

Каннабидиол (КБР) продемонстрировал терапевтический потенциал в лечении эпилепсии, множественного склероза, болезни Альцгеймера, Паркинсона и Крона. Несмотря на ее многообещающие последствия и анальгетические, антивоспалительные и аксиолитические свойства, полный потенциал КБР сдерживается низкой растворимостью воды (0,7-10 мкг/мл), низкой проницаемостью и химической нестабильностью. Цель этого исследования состояла в том, чтобы повысить проницаемость кишечника (GI) в результате распада, стабильности и проницаемости кишечника КБР путем создания комплекса КБР-фосфолипид (CBD-PLC). Мы предположи

Multiple myeloma in Niger Delta, Nigeria: complications and the outcome of palliative interventions.

BACKGROUND: Multiple myeloma (MM) is one of the hematological malignancies that require palliative care. This is because of the life-threatening nature and the suffering associated with the illness. The aim of this study is to bring to the fore the complications experienced by people living with MM in the Niger-Delta region of Nigeria and the outcome of various palliative interventions. METHODS: This was a 10-year multi-center retrospective study of 26 patients diagnosed and managed in three major centers in the Niger-Delta region of Nigeria from January 2003 to December 2012.

Circulating Levels of Soluble α-Klotho and FGF23 in Childhood Cancer Survivors: Lack of Association with Nephro- and Cardiotoxicity-A Preliminary Study.

Background/Objectives: The survival rate among pediatric cancer patients has reached 80%; however, these childhood cancer survivors (CCSs) are at a heightened risk of developing chronic conditions in adulthood, particularly kidney and cardiovascular diseases. The aims of this study were to assess the serum α-Klotho and FGF23 levels in CCSs and to determine their association with nephro- and cardiotoxicity. Methods: This study evaluated a cohort of 66 CCSs who remained in continuous remission, with a mean follow-up of 8.41 ± 3.76 years. Results: The results of this study revealed that CCSs exhi

TEMPI Syndrome: Update on Clinical Features, Management, and Pathogenesis.

TEMPI (telangiectasias, elevated erythropoietin level and erythrocytosis, monoclonal gammopathy, perinephric fluid collections, and intrapulmonary shunting) syndrome is a rare and newly defined multisystemic disease, which belongs to "monoclonal gammopathy of clinical significances". Due to its rarity, the etiology, pathogenesis, and clinical features of this disease remain largely unknown. Owing to its hidden and diverse clinical manifestations, missed diagnosis and misdiagnosis are common. In recent years, as more patients (including three fatal cases) were identified, some special clinical
