Microbial analysis of clinical material taken from patients at the Oncology Center, Maria Skłodowkda-Curie Institute in Warsaw in 1997

An analysis was carried out of the microbiological investigations of clinical material samples obtained from the patients of two oncology centres belonging to the Warsaw Oncology Centre. Microorganisms cultured from urine, blood, catheters, smears of wounds and other materials were analysed. From 4839 clinical material samples from the Ursynów centre 1755 bacterial strains were isolated. From 423 samples from the centre in Wawelska Street 171 strains were obtained. In infections of patients from the centres the number of Gram-positive cocci was twice that of Gram-negative rods. In the investigated clinical material S. aureus was the most frequently isolated Gram-positive coccus, while E. coli was the most frequent species among Gram-negative bacteria. In the infections of oncological patients a considerable frequency was noted of yeast-like fungi, especially C. albicans. Particularly disquieting was the increasing number of isolates of C. glabrata and C. krusei strains resistant to fluconazole.     

Genetics Institute Inc.和Whitehead Institute发现EPO受体

两个研究机构的研究人员叙述了登在4月21日《CELL》杂成上的他们的发现。际为EPO的红细胞生成素,是由肾天然产生的激素,它的作用是调节人体细胞的产生。受体是附着在未成熟红细胞外表面的一种蛋白质。当EPO与其受体结合时,便触发了细胞对激素的反应。预测EPO受体的研究将有助于进一步了解红细胞成熟的过程,并能改进对患有威胁生命的血液病的儿童和成人的治疗方法。这一突破还使研究者得以鉴别激素的活性部位并有助于研制模拟EPO活性的底物。     

Infant Botulism in Argentina, 1982––1997

The first cases of infant botulism in Argentina were described in 1982. From 1982 to 1997, 146 cases of infant botulism were diagnosed by the identification of botulinal toxin and Clostridium botulinum in feces. The cases were between 2 and 48 weeks of age: 90% were between 5 and 24 weeks old, and 49% were between 5 and 12 weeks old. Of 93 (64%) patients whose sex was reported, 55 (59%) were male and 38 (41%) were female. By season in which illness occurred, 43 (29%) occurred in winter, 43 (29%) in spring, 36 (25%) in summer and 22 (15%) in autumn. The majority of patients lived in suburban or rural areas. All strains isolated belonged to C. botulinum type A, consistent with the predominance of this type in the soils of Argentina.     

Metazooplankton dynamics in the Salton Sea, California, 1997–1999

The dynamics of metazooplankton populations were studied over 3 years at the saline (43 g l^–1) Salton Sea, California's largest lake. Total abundance was highest in summer following late winter/early spring phytoplankton blooms. At this time, metazooplankton consisted mostly of the copepod, Apocyclops dengizicus, and the rotifer, Brachionus rotundiformis. In August or September, severe crashes in the metazooplankton populations occurred each year in mid-lake due to strong wind events which increased mixing and caused low oxygen and high sulfide concentrations throughout the water column. Larvae of the polychaete worm, Neanthes succinea and the barnacle, Balanus amphitrite were present mostly in late winter and spring. Their scarcity in summer is due in part to persistent anoxic bottom conditions that decrease adult populations and in part to predation by tilapia, an omnivorous fish that has become abundant in the lake since the 1960s. Two Synchaeta species, rotifers not previously reported from the Sea, were abundant in winter and spring and predation on these may have permitted the copepod to persist at low levels through the winter. There were two major changes in metazooplankton dynamics since 1954–1956 in addition to the appearance of the two synchaetid rotifers in the fauna. First, there are now much lower densities of barnacle and polychaete larvae in the fall, probably due to the invasion of the zooplanktivorous fish, tilapia. Second the precipitous crashes now seen in metazooplankton densities, especially the copepod, in late summer-early fall did not occur in the 1950s possibly because fall overturn events did not result in such high sulfide levels.

Thermal, mixing, and oxygen regimes of the Salton Sea, California, 1997–1999

The Salton Sea is a shallow (mean depth = 8 m; maximum depth = 15 m), saline (41–45 g l^–1), intermittently mixing, 57 km long, 980 km² lake located in the arid southwestern United States. The Sea is a wind driven system, with predominant winds paralleling the long axis of the lake, being strongest in spring and weakest in summer and fall. The Sea mixed daily or nearly daily between September and January. During this cooling period, moderate to high levels of dissolved oxygen (3–11 mg l^–1) were found throughout the water column. Mean water column temperature ranged from a minimum of 13–14 °C in early January to a maximum of 30–34 °C in July–September. During most of this warming period, the Sea was thermally stratified but subject to periodic wind driven mixing events. Winds were stronger in spring 1998 than in 1997 or 1999, causing more rapid heating of the lake that year and also delaying onset of anoxic conditions in bottom waters. During summer months, mid-lake surface waters were sometimes supersatured with oxygen, and bottom waters were hypoxic or anoxic with sulfide concentrations > 5 mg l^–1. Oxic conditions (> 1 mg O₂ l^–1) often extended a few meters deeper nearshore than they did well offshore as a consequence of greater mixing nearshore. Mixing events in late summer deoxygenated the entire water column for a period of days. Consumption of oxygen by sulfide oxidation likely was the principal mechanism for these deoxygenation events. Sulfide concentrations in surface waters were 0.5–1 mg l^–1 approximately 3 days after one mixing event in mid-August 1999. These mixing events were associated with population crashes of phytoplankters and zooplankters and with large fish kills. In the southern basin, freshwater inflows tended to move out over the surface of the Sea mixing with saline lake water as a function of wind conditions. Salinity gradients often contributed more to water column stability than did thermal gradients in the southeasternmost portion of the lake.

The World Maritime University—Sasakawa Global Ocean Institute: A New Institute in a Unique University

Abstract

Building capacity in ocean affairs, the law of the sea, and marine scientific research in relation to the needs of developing countries is an integral part of the U. Convention on the Law of the Sea and associated instruments, including the International Maritime Organization (IMO) treaty regime. This article traces the development of capacity-building initiatives at the World Maritime University (WMU) over the past three decades, including the establishment of the WMU–Sasakawa Global Ocean Institute in 2018. The establishment of the new institute should be viewed within the wider context of the extraordinary philanthropy of the Sasakawa Peace Foundation and the Nippon Foundation in building human resource capacity and in supporting advanced academic research on complicated and contentious ocean issues. The article describes the extensive consultation process that informs the research, education, and capacity development agenda of the new institute, including work on the ocean-related goals of the 2030 Agenda for Sustainable Development.

The Sun Health Research Institute Brain Donation Program: Description and Eexperience, 1987–2007

The Brain Donation Program at Sun Health Research Institute has been in continual operation since 1987, with over 1000 brains banked. The population studied primarily resides in the retirement communities of northwest metropolitan Phoenix, Arizona. The Institute is affiliated with Sun Health, a nonprofit community-owned and operated health care provider. Subjects are enrolled prospectively to allow standardized clinical assessments during life. Funding comes primarily from competitive grants. The Program has made short postmortem brain retrieval a priority, with a 2.75-h median postmortem interval for the entire collection. This maximizes the utility of the resource for molecular studies; frozen tissue from approximately 82% of all cases is suitable for RNA studies. Studies performed in-house have shown that, even with very short postmortem intervals, increasing delays in brain retrieval adversely affect RNA integrity and that cerebrospinal fluid pH increases with postmortem interval but does not predict tissue viability.
