Эпигенетика и метаболическая метаболическая дисфункция при многоразовом склерозе: обзор подходов к травяным лекарствам и текущих клинических испытаний.

Множественный склероз (MS) — сложная аутоиммунная болезнь, характеризующаяся воспалением, обезвоживанием и нейродегенерацией в центральной нервной системе (КНС). Хотя точные причины остаются неясными, недавние исследования подчеркивают важную роль эпигенетических изменений и митохондриальной дисфункции в начале и развитии болезни. Эпигенетические изменения, такие, как метилация ДНК, модификация гистона и регулирование микроРНК, влияют на генное выражение, не изменяя последовательности ДНК, что приводит к иммунной дисрегуляции и воспалению. Аналогичным образом, митохондриальная дисфункция, отме

SEOM clinical guidelines for anaemia treatment in cancer patients (2020).

Anaemia is defined by the presence of haemoglobin (Hb) levels < 13 g/dL in men and 12 g/dL in women. Up to 39% of cancer patients present it at the time of diagnosis and up to 40% have iron deficiency. Anaemia causes fatigue, functional deterioration and a reduction in the quality of life; it has also been associated with a poorer response to anti-tumour treatment and lower survival. Basic diagnostic tests for anaemia are simple and should be a routine part of clinical practice. These guidelines review the available evidence on the use of different therapies for treating anaemia: erythropoiesi

Nanovesicular Drug Delivery Systems for Overcoming Antibiotic Resistance.

Despite the early success of treating bacterial infections with antibiotics, resistance development has become a global problem. Treatment of organisms that have become resistant to common antibacterial agents is challenging and can cause severe and extended illness, longer hospital stays, and increased medical costs. Bacteria may develop antibiotic resistance by multiple biochemical pathways, including target-site gene mutations, decreased permeability, drug uptake or efflux mechanisms that remove the drug from the host cells, and alterations in metabolic pathways. Several strategies to overc

Utilization of redox modulating small molecules that selectively act as pro-oxidants in cancer cells to open a therapeutic window for improving cancer therapy.

There is a rapidly growing body of literature supporting the notion that differential oxidative metabolism in cancer versus normal cells represents a metabolic frailty that can be exploited to open a therapeutic window into cancer therapy. These cancer cell-specific metabolic frailties may be amenable to manipulation with non-toxic small molecule redox active compounds traditionally thought to be antioxidants. In this review we describe the potential mechanisms and clinical applicability in cancer therapy of four small molecule redox active agents: melatonin, vitamin E, selenium, and vitamin C
