Growth and photosynthesis of Chlorella strains from polar,temperate and tropical freshwater environments under temperature stress

Journal of Oceanology and Limnology 2018年第4期36卷 1266-1279页

作者： Kok-Keong LEE Phaik-Eem LIM sze-wan poong Chiew-Yen WONG Siew-Moi PHANG John BEARDALL Institute of Ocean and Earth Sciences University of Malaya Institute of Graduate Studies University of Malaya School of Health Sciences International Medical University National Antarctic Research Centre University of Malaya Institute of Biological Sciences University of Malaya School of Biological Sciences Monash University

Elevated temperatures as a consequence of global warming have significant impacts on the adaptation and survival of microalgae which are important primary producers in many ecosystems. The impact of temperature on the photosynthesis of microalgae is of great interest as the primary production of algal biomass is strongly dependent on the photosynthetic rates in a dynamic environment. Here, we examine the effects of elevated temperature on Chlorella strains originating from different latitudes, namely Antarctic, Arctic, temperate and tropical regions. Chlorophyll fluorescence was used to assess the photosynthetic responses of the microalgae. Rapid light curves(RLCs) and maximum quantum yield( F_v/F_m) were recorded. The results showed that Chlorella originating from different latitudes portrayed different growth trends and photosynthetic performance. The Chlorella genus is eurythermal, with a broad temperature tolerance range, but with strain-specific characteristics. However, there was a large overlap between the tolerance range of the four strains due to their "eurythermal adaptivity". Changes in the photosynthetic parameters indicated temperature stress. The ability of the four strains to reactivate photosynthesis after inhibition of photosynthesis under high temperatures was also studied. The Chlorella strains were shown to recover in terms of photosynthesis and growth(measured as Chl a) when they were returned to their ambient temperatures. Polar strains showed faster recovery in their optimal temperature compared to that under the ambient temperature from which they were isolated.

Unraveling the ties between irritable bowel syndrome and intestinal microbiota

引用

World Journal of Gastroenterology 2014年第10期20卷 2470-2481页

作者： Sung Noh Hong poong-Lyul Rhee Division of Gastroenterology Department of Medicine Samsung Medical Center Sungkyunkwan University School of Medicine Seoul 135-710 South Korea

Irritable bowel syndrome (IBS) is the most prevalent functional gastrointestinal disorder. It is a multifactorial disorder. Intestinal microbiota may cause the pathogenesis of IBS by contributing to abnormal gastrointestinal motility, low-grade inflammation, visceral hypersensitivity, communication in the gut-brain axis, and so on. Previous attempts to identify the intestinal microbiota composition in IBS patients have yielded inconsistent and occasionally contradictory results. This inconsistency may be due to the differences in the molecular techniques employed, the sample collection and handling methods, use of single samples that are not linked to fluctuating symptoms, or other factors such as patients’ diets and phenotypic characterizations. Despite these difficulties, previous studies found that the intestinal microbiota in some IBS patients was completely different from that in healthy controls, and there does appear to be a consistent theme of Firmicutes enrichment and reduced abundance of Bacteroides. Based on the differences in intestinal microbiota composition, many studies have addressed the roles of microbiota-targeted treatments, such as antibiotics and probiotics, in alleviating certain symptoms of IBS. This review summarizes the current knowledge of the associations between intestinal microbiota and IBS as well as the possible modes of action of intestinal microbiota in the pathogenesis of IBS. Improving the current level of understanding of host-microbiota interactions in IBS is important not only for determining the role of intestinal microbiota in IBS pathogenesis but also for therapeutic modulation of the microbiota.

Unexpected anterograde amnesia associated with Buscopan used as a predmedication for endocscopy

World Journal of Gastroenterology 2007年第28期13卷 3895-3896页

作者： Hyuk Lee Hee Jung Son poong-Lyul Rhee Jae J Kim Jong Chul Rhee Departments of Medicine Samsung Medical CenterSungkyunkwan University School of MedicineSeoul 135-710Korea Departments of Medicine Samsung Medical CenterSungkyunkwan University School of MedicineSeoul 135-710Korea Center for Health PromotionSamsung Medical CenterSungkyunkwan University School of MedicineSeoul 135-710Korea

It has been known that peripheral adverse event is caused by peripheral antimuscarinic action, from hyoscine butylbromide (Buscopan; Boehringer Ingelheim, Germany) used as a premedication for endoscopy. However, symptoms or signs associated with the central nervous system are rarely reported in the field of anesthesiology and peripartum labor. This central anticholinergic syndrome is likely caused by blockade of muscarinic cholinergic receptors in the central nervous system. There is no report on Buscopan-induced central anticholinergic syndrome in endoscopy room so far. Three middle-aged females unexpectedly suffered from anterograde amnesia after intramuscular injection of hyoscine butylbromide as an antispasmodic premedication for endoscopy at our endoscopy unit in the Health Promotion Center.

Epstein-Barr virus-associated lymphoepithelioma-like early gastric carcinomas and endoscopic submucosal dissection: Case series

引用

World Journal of Gastroenterology 2014年第5期20卷 1365-1370页

作者： Ji Young Lee Kyoung-Mee Kim Byung-Hoon Min Jun Haeng Lee poong-Lyul Rhee Jae Jun Kim Department of Medicine Samsung Medical Center Sungkyunkwan University School of Medicine Department of Pathology Samsung Medical Center Sungkyunkwan University School of Medicine

Epstein-Barr virus (EBV)-associated lymphoepithelioma-like gastric carcinoma (LELC) is characterized by a lower lymph node (LN) metastasis rate and a higher survival rate than other forms of gastric cancer. Although current prognosis for LELC is favorable, the most common approach is radical gastrectomy involving an extensive D2 lymph node dissection. Here, we report four cases of EBV-associated early LELC that were treated by an alternative approach, endoscopic submucosal dissection (ESD). The long-term outcome of this procedure is discussed. All patients were treated by ESD en bloc, and all ESD specimens showed tumor-free lateral resection margins. None of the lesions showed lymphovascular invasion. A pathological examination of ESD specimens revealed submucosal invasion of more than 500 μm in all four cases. One patient underwent additional radical surgery post-ESD; no residual tumor or LN metastasis was noted in the surgical specimen. The other three patients did not undergo additional surgery, either because of severe comorbidity or their refusal to undergo operation, but were subjected to medical follow-up. None of the ESD-treated patients reported local recurrence or distant metastases during the 27-32 mo of follow-up after ESD.
