概括
氧醇 (HT) 有效地对抗由高级糖化终产物 (AGEs) 引起的皮肤衰老. 这种天然化合物可以改善皮肤的水分,厚度和原,同时也可以增强肠道屏障功能.
科学领域:
- 皮肤病学和衰老研究研究.
- 营养药品和天然产品化学
- 胃肠病学和肠道健康
背景情况:
- 饮食中的高级糖化终产品 (AGEs) 加快皮肤衰老,导致化品和健康问题.
- 来自橄的抗氧化剂氧化 (HT) 正因其抗衰老特性而受到研究.
- 了解AGE对皮肤的影响以及HT的潜在保护作用至关重要.
研究的目的:
- 为了评估氧醇 (HT) 对老年化瘤诱导的皮肤老化对小鼠的保护作用.
- 评估HT对皮肤水分,厚度,原蛋白含量,氧化应激和炎症的影响.
- 调查HT对肠道屏障功能的影响.
主要方法:
- 48只8个月大的雄性C57BL/6J小鼠被分为对照,AGE模型和两个HT治疗组 (HT25,HT50).
- 小鼠接受了16周的治疗,在干预后采集了皮肤,血清和阴茎样本.
- 分析了皮肤和肠道组织的各种生物标志物,包括水分,厚度,原蛋白,氧化应激标志物 (SOD,GSH-Px,MDA),炎症细胞因子 (IL-6,IL-1β,TNF-α) 和紧密结合蛋白 (ZO-1,ocludin).
主要成果:
- 高剂量的HT (HT50) 显著增加了皮肤水分,表皮和皮肤厚度以及氧水平.
- 通过降低马隆迪化物 (MDA) 和增加超氧化物脱氧酶 (SOD) 和谷氨过氧酶 (GSH-Px) 活动,HT治疗减少了氧化应激.
- 通过增加ZO-1和奥克卢丁的表达,HT干预显著降低了炎症性细胞因子 (IL-6,IL-1β,TNF-α) 的水平,并增强了肠道屏障完整性.
结论:
- 氧醇 (HT) 对皮肤衰老有显著的益处,改善了水分,厚度和原蛋白含量.

The Effect of Aging on Tissues
3.4K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Aging
612
Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

Radical Autoxidation
3.1K
The oxidation of an organic compound in the presence of air or oxygen is called autoxidation. For example, cumene reacts with oxygen to form hydroperoxide. Autoxidation involves initiation, propagation, and termination steps. Many organic compounds are susceptible to autoxidation—especially ethers in the presence of oxygen, which form hydroperoxides. Even though this reaction is slow, old ether bottles contain small amounts of peroxide, which leads to laboratory explosions during ether...

Renewal of Skin Epidermal Stem Cells
3.0K
The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption
229
As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...
