Protein Families02:47

Protein Families

17.2K
Protein families are groups of homologous proteins; that is, they have similarities in amino acid sequences and three-dimensional structures. Protein families usually occur because of gene duplication, where an additional copy of a gene is inserted into the genome of an organism.   Mutations that change the amino acids but still allow the protein to be properly synthesized, will lead to new protein family members.   If these new proteins contain similar amino acids in key...

Gene Families

10.0K
Gene families consist of groups of genes proposed to have originated from a common ancestor. Typically these arise through events in which a gene or genes are mistakenly duplicated during cell division. Unlike their parent genes (which are subject to selection pressure to maintain function), these gene copies do not need to preserve their sequences and may evolve at a relatively faster rate.
Occasionally these regions can be adapted to take on new roles within the organism, becoming novel genes...

Family Therapy

620
Family therapy conceptualizes psychological challenges as arising from dysfunctional interactions within the family unit, rather than as isolated issues within individuals. This approach seeks to address and transform the patterns of communication, roles, and relationships within families to promote healthier dynamics and emotional well-being for all members.

Sources of Self-Esteem I: Family Experience

197
Self-esteem, a crucial component of psychological development, is significantly shaped by familial experiences. The early parent-child relationship serves as a foundational influence on a child's self-concept, with long-lasting effects extending into adolescence and adulthood.Parental Behaviors and Early Self-Esteem FormationEmpirical studies have identified four principal parental behaviors that foster healthy self-esteem in children. These include expressions of acceptance, affection, and...

Area of Science:

  • Dermatology
  • Toxicology
  • Genetics

Background:

  • Chloracne is a severe acne-like skin condition often caused by exposure to chlorinated aromatic hydrocarbons.
  • Familial clustering suggests a potential genetic predisposition interacting with environmental triggers.

Observation:

  • An 11-year-old boy exhibited widespread comedonal lesions, hyperpigmented conjunctivae, enlarged meibomian glands, and nail hyperpigmentation.
  • Respiratory symptoms including cough and fever, mild anemia, and leukocytosis were noted.
  • Affected siblings and parents, with the father experiencing severe hepatic failure and skin manifestations post-pesticide exposure.

Findings:

  • Clinical presentation and family history strongly indicated chloracne.
  • Histologic examination confirmed the diagnosis.
  • Pesticide and herbicide exposure identified as a likely etiological factor.

Implications:

  • Highlights the severe dermatological and systemic effects of toxic chemical exposure.
  • Underscores the importance of considering environmental toxins in familial dermatological conditions.
  • Suggests a need for further investigation into genetic susceptibility factors in chloracne development.
