Ureter Injury in Laparoscopic Para-Aortic Lymphadenectomy for Endometrial Cancer by the Transperitoneal Approach.

The patient was 66 years old, had three pregnancies and two deliveries, and was menopausal at the age of 51. She had irregular bleeding and was found to have a chicken-egg-sized uterus and a thickened endometrium (23 mm). She underwent laparoscopic surgery for uterine endometrial cancer (endometrioid carcinoma G1, stage IB).

Ureter Injury in Total Laparoscopic Hysterectomy.

Objective: To identify surgical manipulations that caused ureter injury during total laparoscopic hysterectomy (TLH) and evaluate the surgical manipulations to identify ways to prevent such injury. . This single-center, cross-sectional study included 1135 cases of TLH performed for benign diseases from January 2009 to December 2021.

Emotional response evoked by viewing facial expression pictures leads to higher temporal resolution.

We examined the effects of emotional response, with different levels of valence and arousal, on the temporal resolution of visual processing by using photos of various facial expressions. As an index of the temporal resolution of visual processing, we measured the minimum lengths of the noticeable durations for desaturated photographs using the method of constant stimuli by switching colorful facial expression photographs to desaturated versions of the same photographs. Experiments 1 and 2 used facial photographs that evoke various degrees of arousal and valence.

Gastrointestinal Stromal Tumor with Repeated Multiple Cerebral Infarction Mimicking Ovarian Cancer with Trousseau's Syndrome.

We report a case of gastrointestinal stromal tumor (GIST) with repeated multiple cerebral infarctions mimicking ovarian cancer. A 79-year-old postmenopausal woman had multiple cerebral infarctions with a giant pelvic tumor detected by computed tomography. Ovarian cancer with Trousseau's syndrome was suspected.

Robot-assisted laparoscopic hysterectomy for endometrial cancer in a patient with Herlyn-Werner-Wunderlich syndrome.

Herlyn-Werner-Wunderlich syndrome, a rare Mullerian duct anomaly, includes a triad of uterine didelphys, obstructed haemivagina and ipsilateral renal agenesis. A 58-year-old woman with Herlyn-Werner-Wunderlich syndrome, reported of recurrent genital bleeding for 9 years, was finally diagnosed with endometrial cancer. She had a history of vaginal septum resection and nephrectomy of atrophic right kidney.

A Case of Trousseau's Syndrome Accompanying Ovarian Cancer with Widespread Thromboembolisms.

The patient was a 41-year-old woman, gravida 0. She had no notable medical history. Laparoscopic right salpingo-oophorectomy and left cystectomy were performed for bilateral ovarian endometriomas, which were both pathologically diagnosed as benign.

Generation of rat induced pluripotent stem cells using a plasmid vector and possible application of a keratan sulfate glycan recognizing antibody in discriminating teratoma formation phenotypes.

Induced pluripotent stem cells (iPSCs) offer an invaluable tool for biological research and regenerative medicine. We report establishment of rat iPSCs (riPSCs) using a plasmid vector encoding four transcription factors, Oct3/4, Sox2, c-Myc and Klf4. Although all riPSC clones were generated and cultured under the same conditions, expressed hallmark pluripotency markers and differentiated successfully in vitro, the expression of a keratan sulfate glycan epitope with unique properties defined by R-10G antibody varied in the riPSC clones.

Involvement of KRAS G12A mutation in the IL-2-independent growth of a human T-LGL leukemia cell line, PLT-2.

Cytokine-dependent cell lines have been used to analyze the cytokine-induced cellular signaling and the mechanism of oncogenesis. In the current study, we analyzed MOTN-1 and PLT-2 cell lines established from different stages of a T-cell large granular lymphocyte leukemia patient (Daibata et al. 2004).

Transcriptional regulation of neutral sphingomyelinase 2 in all-trans retinoic acid-treated human breast cancer cell line, MCF-7.

Effects of all-trans retinoic acid (ATRA) on sphingomyelinase expression were examined using MCF-7 (ATRA-sensitive) and MDA-MB-231 (ATRA-resistant) breast cancer cells. Increased NSMase activity, NSMase2 mRNA and protein were observed in ATRA-treated MCF-7 but not in ATRA-treated MDA-MB-231. Increased NSMase2 mRNA of ATRA-treated MCF-7 was mostly due to enhanced transcription.

Sphingosine kinase 1/S1P pathway involvement in the GDNF-induced GAP43 transcription.

Glial cell line-derived neurotrophic factor (GDNF) is important for the development and maintenance of dopamine neurons (Lin et al. [1993] Science 260: 1130-1132). GDNF is neuroprotective in animal models of Parkinson disease, where dopamine neurons show selective degeneration.

Heterogeneous sphingosine-1-phosphate lyase gene expression and its regulatory mechanism in human lung cancer cell lines.

The role of sphingolipid metabolic pathway has been recognized in determining cellular fate. Although sphingolipid degradation has been extensively studied, gene expression of human sphingosine 1-phosphate lyase (SPL) catalyzing sphingosine 1-phosphate (S1P) remains to be determined. Among 5 human lung cancer cell lines examined, SPL protein levels paralleled the respective mRNA and enzyme activities.
