Prognosis of breast cancer during pregnancy: evidence for nursing care.

This integrative review analyzed evidence available in the literature concerning the prognosis of breast cancer during pregnancy. The following databases were used for selecting studies: PubMed, CINAHL and LILACS. A total of 240 primary studies were identified; 13 papers were included in the integrative review's sample after reading the titles and abstracts and according to the established inclusion and exclusion criteria.

Effect of laser on the remnant liver after the first 24 hours following 70% hepatectomy in rats.

Purpose: To evaluate the mitochondrial function of the remnant liver (RL) in the early phase of liver regeneration in rats after 70% partial hepatectomy (PH).

Methods: Sixty male Wistar rats (200-250g) submitted to 70% PH were divided into five groups according to the time of euthanasia and application or not of laser light: C = Control, time zero; 2 minutes, 4, 6 and 24 hours after PH. The dose of laser radiation was 22.

The effect of laser on remanescent liver tissue after 90% hepatectomy in rats.

Purpose: To evaluate the effect of laser beam on reminiscent liver after partial hepatectomy 90%.

Methods: Wistar rats, (N=42), were divided into six groups with seven specimens each. The partial hepatectomy (HP) was performed in all animals through exeresis of approximately 90% of the liver parenchyma.

Enhancement of liver regeneration by the association of Hyptis pectinata with laser therapy.

Since new molecules that normally would accelerate regeneration can also be potentialized by light, the use of new substances combined with laser therapy seems to be a natural type of experiment. Therefore, the purpose of this study was to assess the effects of Hyptis pectinata leaves on liver regeneration after partial hepatectomy (PH) associated with laser therapy. Twenty-four rats were divided into four groups--PH(control), PHL (laser therapy), PH200 (200 mg/kg of Hyptispectinata), and PHL200 (200 mg/kg of the plant and laser)--which were submitted to 67% hepatectomy.
