Background: Although the effects of exercise training (ET) on sleep problem have been reported, the effects according to the components of exercise, including intensity, frequency, and time window, are unknown. Thus, in this study, we aimed to assess the effects of ET on sleep quality in community-dwelling older adults with sleep problems.

Methods: We evaluated individuals aged ≥65 years whose Pittsburgh sleep quality index was >5 points at baseline.

Aim: To investigate the effects of high-intensity interval exercise training on microvascular endothelial function among community-dwelling older people.

Methods: We analyzed the data from a nonrandomized controlled trial. This study's participants were 48 men (aged 75 ± 5 years; exercise training group, n = 24; control group, n = 24) and 83 women (aged 75 ± 4 years; exercise training group, n = 36; control group, n = 47).

Background: The hypotensive effects of high-intensity interval training have been reported; however, studies on older adults are few. This study aimed to examine whether interval-walking training (IWT), a home-based program of high-intensity interval training, reduces blood pressure (BP) levels when compared with a non-intervention group in community-dwelling older adults.

Methods: An intervention study was conducted with 55 men (age, 75±5 years; IWT/control groups, N.

Background: Most malignancies lack tumor-associated antigens, which are recognized by T-lymphocytes through major histocompatibility complex (MHC) molecules, and seem to evade host immunological defense. In this study, we investigated whether allogeneic MHC gene transfer into the low-antigenic tumor might induce cell-mediated immunity, and provide an immunotherapeutic effect in vivo.

Materials And Methods: Mammary adenocarcinoma cells (MAT B III) originated from an F344 rat (RT1A(l)) were transfected with a plasmid DNA encoding RT1A(a) (pcMRT1A) in vitro.

Background/aims: Depression of cell-mediated immunity frequently accompanies solid tumor malignancy, and appears to be worsened as the disease progresses. In this study, we investigated cell-mediated immune status in colorectal cancer patients.

Methodology: Interleukin-2 (IL-2) productivity by phytohemagglutinin (PHA)-stimulated non-adherent peripheral blood mononuclear cells (PBMC), and prostaglandin E2 (PGE2) productivity by LPS-stimulated adherent PBMC were investigated in colorectal cancer patients with hepatic metastasis (n=20) and without hepatic metastasis (n=20), and in non-malignant disease controls (n=20).

Background/aims: Recurrence of the remnant liver or extrahepatic sites after hepatic resection for colorectal metastases is concerned as a significant prognostic factor. While regional chemotherapy may reduce recurrence of the liver, appropriate therapy for extrahepatic metastases needs to be elucidated.

Methodology: We identified 207 patients undergoing hepatectomy for colorectal metastases.

Background: Although extracellular heat-shock protein 70 (Hsp70) potentially mediates an inflammatory response, the association of circulating Hsp70 with complications after surgery is poorly understood.

Methods: Perioperative plasma concentrations of Hsp70 and interleukin-6 were measured by immunoassays in 64 consecutive patients undergoing liver resection.

Results: Plasma concentrations of Hsp70 and interleukin-6 showed a striking increase immediately after surgery, and on postoperative day 1.

Objective: Splenectomy is the standard surgical treatment for hereditary spherocytosis, but partial splenic embolization is another potential option. We retrospectively studied the therapeutic effects of partial splenic embolization as a treatment for hereditary spherocytosis.

Conclusion: Partial splenic embolization is a safe and effective alternative to splenectomy or partial splenectomy in the treatment of hereditary spherocytosis.

Human hepatocellular carcinoma (HCC) is a hypervascular tumor but the mechanisms underlying the process of angiogenesis are not fully understood. Angiopoietins (Ang) have been recently identified as ligands for Tie-2 receptor and are thought to be important factors in vascular maturation and stability during angiogenesis. In this study, we investigated the expression of Ang-1, Ang-2, Tie-2, and vascular endothelial growth factor (VEGF) in surgically resected specimens from 46 patients with HCC to determine their potential role in tumor angiogenesis and its progression.
