Clinical Considerations of Ehlers-Danlos Syndrome for Implant Dentistry: Two Case Reports.

Ehlers-Danlos Syndrome (EDS) is a group of congenital connective tissue disorders that commonly affect joints, muscles, soft tissue, and blood circulation in the affected population. Many oral manifestations are displayed in EDS patients that can include gingival recession, lack of attached gingiva, early severe periodontal disease, and dental caries. However, the literature is limited and oftentimes contradictory regarding dental implants in EDS patients.

The Strategy to Use Sugammadex to Reduce Postoperative Pulmonary Complications after da Vinci Surgery: A Retrospective Study.

In 2000, the da Vinci Surgery System was approved by the United States Food and Drug Administration for general laparoscopic surgery and it became the first commercially available robotic surgery system. The aim of this study was to identify the incidence of postoperative pulmonary complications (PPCs) in patients undergoing da Vinci surgery and to observe whether the incidence of PPCs was affected by the usage of Sugammadex. Sugammadex is a gamma-cyclodextrin that encapsulates and subsequently inactivates steroidal neuromuscular blocking agents.

A Sextuple Knockout Cell Line System to Study the Differential Roles of CRY, PER, and NR1D in the Transcription-Translation Feedback Loop of the Circadian Clock.

The transcription-translation feedback loop (TTFL) is the core mechanism of the circadian rhythm. In mammalian cells, CLOCK-BMAL1 proteins activate the downstream genes by binding on the E-box sequence of the clock-controlled genes. Among these gene products, CRY1, CRY2, PER1, PER2, NR1D1, and NR1D2 can regulate the CLOCK-BMAL1-mediated transcription to form the feedback loop.

Prenatal diagnosis of the maternal derivative chromosome der(15)t(Y;15)(q12;p13) in a dizygotic twin pregnancy.

Sex chromosome translocations are unique and must be considered separately from translocations between autosomes. Here, we describe the first prenatal case of one twin fetus with an unbalanced translocation between chromosome Y and chromosome 15, presenting a 46,XY,der(15)t(Y;15) karyotype. The other twin had a normal 46,XY karyotype.

A retrospective study of sodium hypochlorite pulpotomies in primary molars.

Background/purpose: Formocresol has been a popular pulpotomy medicament for primary molars, however, its toxicity and potential carcinogenicity leaves room for other alternatives such as sodium hypochlorite (NaOCl). The purpose of this study is to evaluate the clinical and radiographic success rate of 5% NaOCl pulpotomy in primary molars.

Materials And Methods: A retrospective research of patient records from January 1, 2009 and December 31, 2012 was conducted to evaluate the clinical and radiographic success rate of 5% NaOCl pulpotomy in primary molars.

KIT Exon 11 Codons 557-558 Deletion Mutation Promotes Liver Metastasis Through the CXCL12/CXCR4 Axis in Gastrointestinal Stromal Tumors.

Purpose: KIT mutations, the most prevalent genetic event in gastrointestinal stromal tumors (GIST), are associated with malignant features and poor prognosis. Aggressive GISTs possess a high propensity to spread to the liver. This study aimed to explore the role of KIT mutations in GIST liver metastasis.

Discrepancy of cytogenetic analysis in Western and eastern Taiwan.

Objective: This study aimed at investigating the results of second-trimester amniocyte karyotyping in western and eastern Taiwan, and identifying any regional differences in the prevalence of fetal chromosomal anomalies.

Methods: From 2004 to 2009, pregnant women who underwent amniocentesis in their second trimester at three hospitals in western Taiwan and at four hospitals in eastern Taiwan were included. All the cytogenetic analyses of cultured amniocytes were performed in the cytogenetics laboratory of the Genetic Counseling Center of Hualien Buddhist Tzu Chi General Hospital.

Effects of light availability on the biomass production, CO2 fixation, and bioethanol production potential of Thermosynechococcus CL-1.

A thermophilic cyanobacterium named Thermosynechococcus CL-1 (TCL-1) was cultivated in this study to eliminate the energy input of cooling system in flat plate photobioreactors. Cultivating TCL-1 in the 1.5 cm light path flat plate photobioreactor exhibited stable characteristics for biomass production, CO2 fixation, and carbohydrate production under high illumination conditions (1000 or 2000 μE m(-2) s(-1)).

Analysis of earthy and musty odors in water samples by solid-phase microextraction coupled with gas chromatography/ion trap mass spectrometry.

A method for the determination of the earthy and musty odors geosmin, 2-methylisoborneol (2-MIB), 2-isobutyl-3-methoxy pyrazine (IBMP), 2-isopropyl-3-methoxy pyrazine (IPMP) and 2,4,6-trichloroanisole (2,4,6-TCA) in water by headspace solid-phase microextraction (HSSPME) combined with gas chromatography-ion trap mass spectrometry (GC-ITMS) is described. Several parameters of the extraction and desorption procedure were studied and optimized (such as types of fibers, extraction temperature, extraction time, desorption temperature, desorption time, ionic strength and elutropic strength and pH of samples). The method shows good linearity over the concentration range 1-500ngl(-1) and gives detection limits of sub-part per trillion levels for all compounds.

Evolutional change of karyotype with t(8;9)(p22;p24) and HLA-DR immunophenotype in relapsed acute myeloid leukemia.

The rare recurrent translocation of (8;9)(p22;p24) with PCM1-JAK2 fusion was recently characterized in diverse hematological malignancies. Most of them are atypical chronic myeloid leukemia (CML) or other myeloproliferative disorders (MPD), and are predominantly in the male. We report a female patient with acute myeloid leukemia (AML) initially presenting with normal karyotype and negative HLA-DR expression who achieved complete remission after standard chemotherapy.

Analysis of the saliva from patients with oral cancer by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry.

Using matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS), this study analyzed the saliva obtained from patients with oral cancer and compared these mass spectra with those obtained from healthy controls. Saliva without pre-treatment was mixed directly with a sinapinic acid matrix. Alpha-amylase (57 kDa) dominated the high mass range in the MALDI mass spectra of the saliva from healthy subjects, but the peak was suppressed for patients with oral cancer and was replaced by a peak at m/z 66 k in the spectra of patients' samples (15 out of 20).
