One aerobic, Gram-stain-negative, rod-shaped bacterium, designated strain RB1R5T, was isolated from Renlongba glacierin Tibet Autonomous Region, China. Growth was observed at 4–25°C and pH 7.0–8.0. Phylogenetic analysis based on 16SrRNA gene sequences revealed that strain RB1R5T belongs to the genus Flavobacterium, and its closest relatives are Flavobacterium luteum IMCC26026T and Flavobacterium psychroterrae CCM 8827T with 97.75 and 97.42% gene sequence similarities,respectively. The average nucleotide identity and DNA–DNA hybridization values between strain RB1R5T and its closest relativeFlavobacterium luteum IMCC26026T were 78.02 and 21.8%, respectively. The major cellular fatty acids were anteiso-C15:0 andsummed feature 3 (comprising C16:1ω7c/C16:1ω6c). The sole menaquinone was MK-6. The major phospholipid was phosphatidylethanolamine. On the basis of phenotypic, phylogenetic and chemotaxonomic characterizations, strain RB1R5T representsa novel species of the genus Flavobacterium, for which the name Flavobacterium psychrotolerans sp. nov. is proposed. The typestrain is RB1R5T (=CGMCC 1.23024T=NBRC 113060T).

Das Konzept der äquivalenten Spannung (Vergleichsspannung) wird seit langem angewendet und hat sich bewährt. Ein wesentlicher Grund dafür liegt darin, dass es u. a. bei der Formulierung phänomenologischer Werkstoffmodelle weiterhilft. Von Nachteil ist, dass es weder mit physikalischen Prinzipien in Verbindung steht, noch Informationen über die Mikrostruktur des Werkstoffs enthält. Trotzdem wurden zahlreiche Hypothesen zur Formulierung von äquivalenten Spannungen in der Vergangenheit aufgestellt und in der Praxis mit unterschiedlichem Erfolg angewendet.

Das Konzept der ?quivalenten Spannung (Vergleichsspannung) wird seit langem angewendet und hat sich bew?hrt. Ein wesentlicher Grund dafür liegt darin, dass es u. a. bei der Formulierung ph?nomenologi-scher Werkstoffmodelle weiterhilft. Von Nachteil ist, dass es weder mit physikalischen Prinzipien in Verbindung steht, noch Informationen über die MikroStruktur des Werkstoffs enth?lt. Trotzdem wurden zahlreiche Hypothesen zur Formulierung von ?quivalenten Spannungen in der Vergangenheit aufgestellt und in der Praxis mit unterschiedlichem Erfolg angewendet. Als Basis für die Systematisierung der zahlreichen Modelle hat Yu die Unified Strength Theory (UST) vorgeschlagen. Diese eignet sich, u.a. inkompressibles inelastisches Materialverhalten sowie kompressible Werkstoffe mit unterschiedlichem Verhalten bei Zug- und Druckbeanspruchung zu beschreiben. In diesem Beitrag wird die Theorie von Yu analysiert, mit existierenden Modellen verglichen und durch einfachere Modelle approximiert. Für das UST-Modell und weitere Modelle werden die plastische Querkontraktionszahl und die maximale hydrostatische Spannung berechnet. Mit Hilfe der Querkontraktionszahl beim Zug und einfacher Spannungsverh?ltniszah- len werden verschiedene Modelle miteinander verglichen. Der relevante Wertebereich der Modellparameter l?sst sich ausgehend von diesen Gr??en einschr?nken. Zur Reduktion der Anzahl der Modelle wird in diesem Beitrag eine alternative Systematisierung auf der Basis der geometrischen Eigenschaften der Vergleichsspannungen eingesetzt. In dieser Systematik nimmt das Modell von Yu eine wichtige Position ein.

A health crisis struck China on the cusp of the New Year. Wuhan, a metropolis of 11 million residents in central China's Hubei Prov- ince, became the epicenter of a new coronavirus. As the number of infected cases rapidly rose and the local health care system was under tremendous stress, an unprecedented rescue mission and nationwide battle against the epidemic began.

PCR-Capillary electrophoresis technology was used to identify diatoms in lung, liver and kidney, and to assess the effects of these diatom species. From 20 randomly selected experimental rabbits, which were drowned in the same location, the liver, kidney and lung from each rabbit were removed and diatom DNA was extracted from the tissues of these organs and subsequently amplified by specific primers of the diatom SSU gene. The diatom DNA was then analyzed using PCR-Capillary electrophoresis. When the amount of biomaterial was increased, the number of diatom species detected in the lung, liver and kidney gradually increased, and was statistically significant (P < 0.01). Bivariate correlation analysis showed a positive correlation between the quantity and types of diatoms. The proportion of diatom species detected in each group varied. When the quantity was greater than 0.9 g in the lung, samples including two or more types of diatoms predominated. When the quantity was greater than 1.5 g in the liver, samples including one or more types of diatoms predominated. When the quantity was greater than 2 g in the kidney, samples which included one or more types of diatoms predominated. The number of diatom species found in different organs with different tissue mass was significantly different, and provides a reference for the detection of diatoms using PCR-Capillary electrophoresis technology. This technique also has potential in the forensic identification of drowning.C1 Liu, Chao; Minist Publ Secur, Guangzhou Inst Criminal Sci and Technol, Key Lab Forens Pathol, Guangzhou 510030, Guangdong, Peoples R ChinaSC Science & Technology - Other Topics; Genetics & Heredity; Legal Medicine

Wound healing in diabetic patients is a difficult problem to be solved at present. In addition, patients with diabetes have an increased risk of postoperative wound complications. “She-Xiang-Yu-Hong” (SXYH) ointment is a type of traditional Chinese medicine (TCM) compound used to treat wounds. Over the past few years, SXYH has been applied in the Affiliated Hospital of Chengdu University of TCM (Chengdu, China) for the treatment of diabetic foot infections and bedsores, whereas there has been rare research on the effect of SXYH ointment on wound healing. In this study, SXYH ointment was first applied to streptozotocin (STZ)-triggered diabetic ICR mice (4–6 weeks, 20?±?2?g) to observe the accelerated wound healing and the shortened wound healing period. As indicated by the histology and biochemistry analyses of skin biopsies, the wounds treated using SXYH ointment showed an increase in the granulation tissue. Moreover, SXYH also modulated the inflammation response by regulating affinity proinflammatory cytokines release (e.g., IL-6 and TNF- α ). Furthermore, SXYH ointment obviously improved collagen fiber deposition and tissue on the wound surface. On the whole, this study indicated that SXYH ointment could accelerate wound healing, promote blood vessel formation, and suppress inflammations. Thus, the clinical potential of SXYH ointment was demonstrated in the treatment of diabetes and refractory wounds.
