Polyphenol là các chất chuyển hóa thứ cấp của thực vật và thường tham gia vào
việc bảo vệ chống lại tia cực tím hoặc sự xâm nhập của các tác nhân gây bệnh.
Trong thập kỷ qua, đã có nhiều quan tâm về tiềm năng lợi ích sức khỏe từ
polyphenol thực vật trong chế độ ăn uống như một chất chống oxy hoá. Các nghiên
cứu dịch tễ học và phân tích tổng hợp liên quan mạnh mẽ đến việc tiêu thụ lâu
dài các chế đ... hiện toàn bộ

The balance between oxidation and antioxidation is believed to be critical in
maintaining healthy biological systems. Under physiological conditions, the
human antioxidative defense system including e.g., superoxide dismutase (SOD),
catalase (CAT), glutathione peroxidase (GPx), glutathione (GSH) and others,
allows the elimination of excess reactive oxygen species (ROS) including, among
others supe... hiện toàn bộ
Oxidative stress has been implicated in many chronic diseases. However,
antioxidant trials are so far largely unsuccessful as a preventive or curative
measure. Chronic low‐grade inflammatory process, on the other hand, plays a
central role in the pathogenesis of a number of chronic diseases. Oxidative
stress and inflammation are closely related pathophysiological processes, one of
which can be eas... hiện toàn bộ

Background. There are several health benefits that honeybee products such as
honey, propolis, and royal jelly claim toward various types of diseases in
addition to being food. Scope and Approach. In this paper, the effects of honey,
propolis, and royal jelly on different metabolic diseases, cancers, and other
diseases have been reviewed. The modes of actions of these products have also

Reactive oxygen species (ROS) are by-products of normal cell activity. They are
produced in many cellular compartments and play a major role in signaling
pathways. Overproduction of ROS is associated with the development of various
human diseases (including cancer, cardiovascular, neurodegenerative, and
metabolic disorders), inflammation, and aging. Tumors continuously generate ROS
at increased le... hiện toàn bộ

Increasing interest has recently focused on determining whether several natural
compounds, collectively referred to as nutraceuticals, may exert neuroprotective
actions in the developing, adult, and aging nervous system. Quercetin, a
polyphenol widely present in nature, has received the most attention in this
regard. Several studies in vitro, in experimental animals and in humans, have
provided su... hiện toàn bộ
Manganese (Mn) is an essential element that is involved in the synthesis and
activation of many enzymes and in the regulation of the metabolism of glucose
and lipids in humans. In addition, Mn is one of the required components for Mn
superoxide dismutase (MnSOD) that is mainly responsible for scavenging reactive
oxygen species (ROS) in mitochondrial oxidative stress. Both Mn deficiency and
intoxic... hiện toàn bộ
About 246 million people worldwide had diabetes in 2007. The global figure of
people with diabetes is projected to increase to 370 million in 2030. As the
prevalence of diabetes has risen to epidemic proportions worldwide, diabetic
nephropathy has become one of the most challenging health problems. Therapeutic
options such as strict blood glucose and blood pressure controls are effective
for preve... hiện toàn bộ

The prevalence of diabetes mellitus (DM) is increasing worldwide, a consequence
of the alarming rise in obesity and metabolic syndrome (MetS). Oxidative stress
and inflammation are key physiological and pathological events linking obesity,
insulin resistance, and the progression of type 2 DM (T2DM). Unresolved
inflammation alongside a “glucolipotoxic” environment of the pancreatic islets,
in insul... hiện toàn bộ
