S100A16 up-regulates Oct4 and Nanog expression in cancer stem-like cells of Yumoto human cervical carcinoma cells.

Cancer stem-like cells (CSCs), which possess the ability to self-renewal and are multipotent, are regarded as the cause of tumor formation, recurrence, metastasis and drug resistance. It is necessary to understand the properties of CSCs in order to treat them effectively. It has been previously reported that S100 family proteins, which carry calcium-binding EF-hand motifs and are associated with tumorigenic processes, serve crucial roles in maintaining cancer stem-like properties.

Efficacy and Safety of a Single-Pill Fixed-Dose Combination of Azilsartan and Amlodipine.

Background: Guidelines for the management of hypertension recommend the use of drugs with different mechanisms of action in antihypertensive regimens that include single-pill fixed-dose combinations of medications. There is some controversy regarding which single-pill fixed-dose combinations of angiotensin II type 1 receptor blockers (ARBs) and calcium channel blockers (CCBs) are effective at reducing blood pressure (BP).

Methods: Forty hypertensive patients who were receiving a single-pill fixed-dose combination of valsartan 80 mg/day and amlodipine 5 mg/day or irbesartan 100 mg/day and amlodipine 5 mg/day were enrolled.

[Jejunal duplication in an adult presenting with hematochezia].

A 56-year-old man was admitted to our hospital with appetite loss, palpitations, orthostatic syncope, and hematochezia. Contrast-enhanced abdominal computed tomography (CT) revealed a proximal jejunal diverticulum with contrast extravasation. We immediately performed transoral double balloon enteroscopy (DBE) to treat the bleed in the jejunum, and this revealed a small ulcer with an exposed vessel at the opening of the jejunal diverticulum.

Efficacy and safety of two single-pill fixed-dose combinations of angiotensin II receptor blockers/calcium channel blockers in hypertensive patients (EXAMINER study).

Background: There is some controversy regarding which single-pill fixed-dose combinations of angiotensin II type 1 receptor blockers (ARBs) and calcium channel blockers (CCBs) are effective at reducing blood pressure (BP).

Methods: Sixty hypertensive patients who received a single-pill fixed-dose combination of valsartan 80 mg/day and amlodipine 5 mg/day were enrolled (UMIN Registration 000013460). They were randomly divided into two treatment groups [single-pill fixed-dose combination therapy with valsartan 80 mg/day and amlodipine 5 mg/day (Val/Am group), or irbesartan 100 mg/day and amlodipine 5 mg/day (Irb/Am group)] and treated for 16 weeks.

Association Between Visit-to-Visit Variability in Blood Pressure and Cardiovascular Events in Hypertensive Patients After Successful Percutaneous Coronary Intervention.

Background: Visit-to-visit variability (VVV) in blood pressure (BP) in addition to high BP has been shown to be a strong predictor of coronary events and stroke. Therefore, we investigated the associations between VVV in BP or BP levels and cardiovascular events after successful percutaneous coronary intervention (PCI).

Methods: We enrolled 176 hypertensive patients who had undergone successful PCI and who had four clinic visits to measure BP until follow-up coronary angiography (CAG) at 6 - 9 months after PCI.

[Two cases of recurrent GIST successfully treated with imatinib mesylate at 100mg/day].

Case 1: Recurrent tumors from gastric GIST in the liver and the abdominal wall showed partial response with 200mg/day imatinib and maintained partial response at 100mg/day. Case 2: Metastatic liver tumors from the jejunal GIST showed partial response with 200mg/day imatinib. The tumors have been enlarged for interruption of imatinib administration, however, re- treatment with imatinib resulted in partial response again and kept partial response at 100mg/day of imatinib.

[A case of recurrent breast cancer with lung metastasis resection showing four disease-free years under trastuzumab treatment].

We report a case of recurrent breast cancer with solitary lung metastasis that has shown no recurrence with treatment by trastuzumab alone after partial resection of the right lung upper lobe. A 56-year-old woman, who presented with left breast cancer, underwent quadrantectomy and axillar lymph node dissection in March 2004. Pathological findings were as follows: invasive ductal carcinoma, 3.

Clinical usefulness of a collimator distance dependent resolution recovery in myocardial perfusion SPECT: a clinical report from a single institute.

Objective: Imperfect image resolution because of finite-sized collimator channels often causes a decrease in diagnostic performance in myocardial perfusion single-photon emission computed tomography (SPECT). This prompted us to evaluate the clinical usefulness of collimator distance dependent resolution recovery (RR) in myocardial perfusion SPECT.

Methods: We retrospectively reviewed myocardial SPECT images of 60 consecutive patients (26 men, 34 women; mean age 68 years).

Safety, efficacy and pharmacokinetics of S-1 in a hemodialysis patient with advanced gastric cancer.

Purpose: The safety and efficacy of S-1 in hemodialysis patients have not been established. We evaluated the safety and efficacy and pharmacokinetics of S-1 in a hemodialysis patient with advanced gastric cancer.

Patient: A 66-year-old Japanese man with chronic renal failure, who had undergone hemodialysis three times a week for 3 years.

[A case of gastric gastrointestinal stromal tumor operated after low-dose chemotherapy with imatinib mesylate].

A 76-year-old man was admitted to our hospital because of tarry motions. Endoscopic findings showed an ulcer on a large submucosal tumor in the stomach. Abodminal CT scan showed a protruding lesion of approximately 13 cm at the lumen of the gastric body.

[Good response in ARDS treated with sivelestat sodium hydrate during chemotherapy for cholangiocarcinoma].

We experienced a case of good response in acute respiratory distress syndrome (ARDS) treated with sivelestat sodium hydrate during chemotherapy for cholangiocarcinoma. A 66-year-old male treated with combined paclitaxel (PTX) and S-1 suffered from ARDS following neutropenia. Sputum and blood culture examinations demonstrated an unknown origin, so sivelestat sodium hydrate was considered more effective than antibiotics.
