Infection01:20

Infection

11.6K
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Urinary Tract Infection II: Pathophysiology

524
The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...

Cystic Fibrosis: Pathogenesis

676
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Stages of Infection

64.7K
Stages of infection describe what happens to a susceptible host once a pathogen invades the human body. The stages of infection are incubation, prodromal, illness, stage of decline, and convalescence. The incubation stage is the period from exposure to a pathogen until symptoms start. The infected person is unaware of impending illness as the pathogens grow and multiply within the body. The duration may vary depending on the type of infection. The incubation period of measles averages ten to...

Defense Against Bacterial Pathogens01:31

Defense Against Bacterial Pathogens

2.6K
The human immune system is a complex network of cells, tissues, and organs that work together to defend the body against bacterial infections. It consists of various immune cells, each playing a specific role in the defense mechanism.
Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...

科学分野:

  • 神経科学; 遺伝学; 老年学

背景:

  • 人口の高齢化は、認知機能低下および神経認知障害のリスク増加と関連している。
  • アポリポタンパク質E(APOE)ε4アレルは、アルツハイマー病の重要な遺伝的リスク因子である。
  • 身体活動(PA)は、認知機能を維持するための潜在的な非薬理学的介入として認識されている。

研究 の 目的:

  • 健常高齢者の認知機能と身体活動との関連を調査する。
  • この関連におけるアポリポタンパク質E(APOE)遺伝子型の影響を調べる。
  • APOEの状態、身体活動、および認知機能の関係を高齢者で探求する。

主な方法:

  • 83人の認知機能が健常なブラジル人高齢者を対象とした横断観察研究。
  • 参加者はAPOE ε4アレル状態(キャリア対非キャリア)について遺伝子型を決定した。
  • 認知機能はAddenbrooke's Cognitive Examination-Revised(ACE-R)を用いて評価した。
  • 統計解析にはANCOVAが含まれた。

主要な成果:

  • APOE ε4キャリアは認知機能が低下し、APOEの状態は認知結果に有意に影響を与えた(p=0.039)。
  • APOE ε4キャリアと非キャリアの間で、認知または社会人口統計学的変数に統計学的に有意な差は認められなかった。
  • 身体活動は、APOEの状態を調整した後、グローバル認知と独立した関連はなかった(p=0.644)。

結論:

  • APOE ε4キャリアの状態は、認知機能が正常な高齢者の認知機能に明らかに影響を与える。
  • 身体活動は、この特定のサンプルでは認知機能と独立した関連を示さなかった。
  • APOEの状態のような遺伝的要因は、身体活動の認知への有益な効果を調節する可能性があり、さらなる縦断的研究が必要である。
