Anal Expulsive

Anal-expulsive is a psychoanalytic concept describing a personality style that Sigmund Freud and later theorists associated with conflicts during the anal stage of psychosexual development and toilet training. In this model, permissive or poorly regulated toilet training was thought to influence later tendencies such as disorganization, impulsivity, emotional expressiveness, or excessive generosity, although these proposed links lack strong empirical support. The concept is therefore best understood as a historical element of psychoanalytic personality theory rather than a clinical diagnosis. Studying anal-expulsive theory helps students evaluate early explanations of personality development and compare them with evidence-based approaches in contemporary psychology.

This stage marks a critical point where children begin to develop a sense of control and mastery over their bodily functions, as well as their broader...

2023

The high incidence of pain after anal surgery is due to the physiological structure and pathological status of the anus. At present, the use of painkillers cannot provide satisfactory pain relief, which makes complementary therapy important. This paper proposes acupoint needle-embedding combined with ironing therapy to relieve postoperative pain.

A Rat Model of Pouchitis Following Proctocolectomy and Ileal Pouch-Anal Anastomosis Using Dextran Sulfate Sodium

This video describes the protocol for generating a patient-derived orthotopic xenograft colorectal cancer mouse model to study the progression of colorectal cancer cells in non-obese diabetic/severe combined immunodeficiency (NOD/SCID) mice. This murine model helps in understanding primary tumor growth and metastases pattern.

Lyme disease research studies often require generation of ticks infected with the pathogen Borrelia burgdorferi, a process that typically takes several weeks. Here we demonstrate a microinjection-based tick infection procedure that can be accomplished within hours. We also demonstrate an immunofluorescence method for in situ localization of B. burgdorferi within ticks.
