Метод газовой хроматографии для количественного определения остаточных растворителей в наноформуляциях.

Описано разработку и проверку метода газовой хроматографии, который является чувствительным, быстрым и специфичным для оценки 19 распространенных растворителей класса 2 и класса 3, часто используемых в формулировке наномедицины. Проверка метода проводилась с использованием системы газовой хроматографии PerkinElmer с детектированием искровой ионизации и колонки Elite 624 Crossbond 6% цианопропилфенил-94% диметилполисилоксана или DB-Fatwax-Ultra Inert с гелием в качестве носителя. Оценены характеристики валидации, такие как линейность, восстановление при добавлении, точность метода, специфичност

Drugs for discoid lupus erythematosus.

BACKGROUND: Discoid lupus erythematosus (DLE) is a chronic form of cutaneous lupus, which can cause scarring. Many drugs have been used to treat this disease and some (such as thalidomide, cyclophosphamide and azathioprine) are potentially toxic. This is an update of a Cochrane Review first published in 2000, and previously updated in 2009. We wanted to update the review to assess whether any new information was available to treat DLE, as we were still unsure of the effectiveness of available drugs and how to select the most appropriate treatment for an individual with DLE. OBJECTIVES: To ass

Chronic pruritus: a narrative review.

Chronic pruritus encompasses a manifestation of several cutaneous, allergic, infectious, neurological, psychological, and systemic conditions, whose etiological investigation and therapeutic strategy can be challenging. This comprehensive review aims to enhance the understanding of pruritus by highlighting important elements in its pathogenesis, including keratinocytes, Merkel cells and mast cells, nerve fibers, histaminergic and nonhistaminergic pathways, and the interaction of itch signals with the central nervous system. Diagnostic evaluation of chronic pruritus may require a meticulous app

Prurigo Nodularis: Pathogenesis and the Horizon of Potential Therapeutics.

Chronic pruritus that lasts for over 6 weeks can present in various forms, like papules, nodules, and plaque types, with prurigo nodularis (PN) being the most prevalent. The pathogenesis of PN involves the dysregulation of immune cell-neural circuits and is associated with peripheral neuropathies, possibly due to chronic scratching. PN is a persistent and challenging condition, involving complex interactions among the skin, immune system, and nervous system. Lesional skin in PN exhibits the infiltration of diverse immune cells like T cells, eosinophils, macrophages, and mast cells, leading to

… High-potency topical corticosteroids, such as betamethasone valerate 0.1% tape, remain the first-line topical therapy for PN. Studies have demonstrated that this tape can reduce pruritus and flatten nodules in PN patients compared to moisturizing itch relief cream alone [ 151 ]. … An occlusive dressing containing betamethasone valerate 0.1% for the treatment of prurigo nodularis.

Systematic review of the tools and outcomes for the assessment of acute radiation dermatitis severity.

Acute radiation dermatitis (ARD) is a common adverse effect experienced by patients undergoing radiation therapy. Effective assessment tools to accurately measure and manage ARD's impact on patients' quality of life and treatment outcomes is needed. The aim of this study was to evaluate the diverse tools and outcome measures used in the assessment of ARD. A systematic review of MEDLINE®, Embase, and Cochrane was conducted for records 1946-March 2024. A total of 423 studies, including 227 randomized controlled trials (RCTs), were included in the analysis. The review identified 58 distinct tools

Cold Atmospheric Pressure Plasma (CAP) as a New Tool for the Management of Vulva Cancer and Vulvar Premalignant Lesions in Gynaecological Oncology.

Vulvar cancer (VC) is a specific form of malignancy accounting for 5-6% of all gynaecologic malignancies. Although VC occurs most commonly in women after 60 years of age, disease incidence has risen progressively in premenopausal women in recent decades. VC demonstrates particular features requiring well-adapted therapeutic approaches to avoid potential treatment-related complications. Significant improvements in disease-free survival and overall survival rates for patients diagnosed with post-stage I disease have been achieved by implementing a combination therapy consisting of radical surgic

In vitro расширила человека CD4+CD25+ регуляционные T клетки, подавляющие распространение Т клеток.

Регулирующие Т клетки (Tregs) оказались критически важными в балансе между автоиммунизацией и терпимостью и были связаны с несколькими аутоиммунными заболеваниями человека. Однако небольшое число трегов в периферии крови ограничивает их терапевтический потенциал. Поэтому мы разработали протокол, который позволит расширить "Трегз" при сохранении их подавляющей активности. Мы изолировали клетки CD4+CD25 hi от человеческой периферической крови и расширили их in vitro в присутствии anti-CD3 и anti-CD28 Магнитные кситы и высокие концентрации внешнего интерлейкина (IL) -2. Траги были эффективно расш
