Objective: To investigate thiol/disulfide homeostasis (TDH) and thioredoxin domain-containing 5 (TXNDC5) level in early and late-onset preeclampsia.Material and methods: In this cross-sectional study, 24 pregnant women with early-onset preeclampsia and 26 pregnant women with late-onset preeclampsia were compared with 30 pregnant women with no obstetric complications. The serum TXNDC5 levels and thiol/disulfide homeostasis were measured.Results: Serum TXNDC5 levels were significantly higher in the early-onset and late-onset preeclampsia groups compared with the control group (p < .05). Native thiol and total thiol levels were significantly lower in the early-onset and late-onset preeclampsia groups than control group. The disulfide levels were found as significantly high in early preeclamptic patients compared to control group (p < .05). The highest levels of TXNDC5 and the lowest levels of native thiol and total thiol were found in early-onset preeclampsia group. No significant difference was found between the patients with early onset and late onset preeclampsia regarding TXNDC5 levels and thiol/disulfide homeostasis (p > .05).Conclusion: Serum TXNDC5 levels were significantly higher in patients with early-onset and late-onset preeclampsia. The dynamic thiol/disulfide homeostasis was impaired in favor of the oxidized state in patients with preeclampsia.

What is Homeostasis?01:16

What is Homeostasis?

Maintaining homeostasis requires that the body continuously maintain its internal conditions. Each physiological condition has a particular set point, from body temperature to blood pressure to levels of certain nutrients. A set point is the physiological value around which the normal range fluctuates. A normal range is a restricted set of values that is optimally healthful and stable. For example, the set point for normal human body temperature is approximately 37°C (98.6°F).

pH Homeostasis01:31

pH Homeostasis

Acid-base homeostasis is essential for maintaining normal physiological activities in humans. The pH of various body fluids is strictly regulated because it is critical for the optimal activity of enzymes involved in metabolic reactions. Enzymes are basically proteins, so, any significant change in pH can affect their structure and activity. In humans, pH is regulated using three primary mechanisms— chemical buffer systems, respiratory regulation, and renal regulation.

Preparation and Reactions of Thiols02:33

Preparation and Reactions of Thiols

Thiols are prepared using the hydrosulfide anion as a nucleophile in a nucleophilic substitution reaction with alkyl halides. For instance, bromobutane reacts with sodium hydrosulfide to give butanethiol.

Skeleton and Calcium Homeostasis01:21

Skeleton and Calcium Homeostasis

Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.

Structure and Nomenclature of Thiols and Sulfides02:17

Structure and Nomenclature of Thiols and Sulfides

Thiols and sulfides are sulfur analogs of alcohols and ethers, respectively, where the sulfur atom takes the place of the oxygen atom. Thus, thiols are generally represented as RSH, where R is an alkyl substituent and —SH is the functional group. On the other hand, in sulfides, the central sulfur atom is bonded to two hydrocarbon groups on either side. Depending upon the type of group, sulfides can be either symmetrical or asymmetrical. Both thiols and sulfides display a bent geometry,...

Glucose Homeostasis: Regulation of Blood Glucose01:02

Glucose Homeostasis: Regulation of Blood Glucose

Carbohydrates consumed through foods are converted into glucose, a crucial energy source for the body. In the prandial state, high blood glucose levels stimulate the secretion of insulin from the pancreas. Insulin inhibits hepatic glucose production and stimulates glucose uptake and metabolism by muscle and adipose tissue. The excess glucose is converted into glycogen and stored in the liver and muscles.
During fasting, when blood glucose levels are low, the pancreas secretes glucagon. it...
