Parental Care

Parental Care

Many animals exhibit parental care behavior, including feeding, grooming, and protecting young offspring. Parental care is universal in mammals and birds, which often have young that are born relatively helpless. Several species of insects and fish, as well as some amphibians, also care for their young.

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

Teratogenicity

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Pathophysiology of Diabetes

Pathophysiology of Diabetes

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility, suggesting a...

Area of Science:

Nutritional science
Developmental biology
Metabolic health

Background:

Increasing global prevalence of metabolic disorders linked to lifestyle.
Early-life nutrition and maternal factors may "program" offspring for metabolic syndrome.
Epidemiological data and animal models suggest a link between maternal obesity/nutrition and offspring obesity.

Purpose of the Study:

To identify specific maternal factors (diet, obesity, weight gain) during critical developmental periods that program metabolic syndrome.
To understand the mechanisms underlying maternal-fetal programming of metabolic disorders.
To inform the development of effective prevention strategies for obesity.

Main Methods:

Review of epidemiological data.
Analysis of established animal models.
Investigation of maternal-fetal relationship complexities.

Main Results:

Evidence suggests a strong association between maternal obesity and nutrition during pregnancy and offspring obesity.
Animal models are crucial for uncovering the physiological mechanisms of developmental programming.
Distinguishing causal factors in the maternal-fetal dyad remains challenging.

Conclusions:

Early-life nutritional environment plays a critical role in metabolic programming.
Targeting maternal factors and critical developmental windows is essential for obesity prevention.
Interventions aimed at curtailing obesity in early life offer a promising strategy against the epidemic.
