基于层次分析法对白垩纪短脉螽科昆虫后足胫节端距的游泳能力检测

短脉螽科是直翅目昆虫的一个中生代灭绝类群,其最重要特征之一是后足胫节末端具有3—4根较长的距,可以分为长刺状、棒状和叶状等3种类型。在假设短脉螽科具有游泳能力条件下,利用层次分析法(Analytic Hierarchy Process,AHP)探讨短脉螽不同后足胫节端距类型对游泳能力的贡献。分析表明短脉螽科昆虫中,具有叶状端距的类型更有利于提高该类昆虫的游泳能力。短脉螽科昆虫后足端距的高分异度,表明该科昆虫在白垩纪的近水环境不同生态位中均具有较好的适应性。

Discrimination between extreme chronotypes using the full and reduced version of the Morningness-Eveningness Questionnaire

The aim of this study was to carry out a comparison of the ability to discriminate between extreme chronotypes, i.e., morning- and evening-types, among the Morningness-Eveningness Questionnaire (MEQ) and its reduced version (rMEQ). To this end a secondary analysis of cohort studies, using two different approaches, was carried out. The first, subjective, relied on the computing of overlap between extreme chronotypes according to their hourly ideal bedtime, get-up time and midpoint of sleep reported at the MEQ and rMEQ, while the second, objective, on the corresponding actual-actigraphic times. At the subjective approach, 2706 participants filled in the MEQ, while 940 the rMEQ (age range of both groups: 18–30 years). The overlap was significantly lower among those who filled the rMEQ than MEQ when considering ideal midpoint of sleep (13.70% and 46.28%, respectively) and get-up time (47.04% and 62.34%, respectively). At the objective approach, 51 participants filled in the MEQ while 52 the rMEQ (age range: 19–30 years in both groups) at the end of one week of actigraphic recording. No significantly different overlap across those who filled the MEQ or rMEQ was observed with reference to the examined actigraphic times. Results of subjective assessment showed as rMEQ more clearly discriminated between extreme chronotypes than MEQ. The attempt to find an objective confirmation did not provide the same results, probably as a consequence of a masking effect by social rhythms.     

Unraveling the essential role in conjugation of the Tra protein of Streptomyces lividans plasmid pIJ101

Plasmid pIJ101 from Streptomyces lividans encodes a single gene, tra, that is essential for both plasmid transfer and mobilization of chromosomes during mating. The tra gene product (Tra) is a membrane protein, a portion of which shows similarity to transfer proteins of other streptomycete plasmids as well as additional bacterial chromosome partitioning proteins. This paper reviews past and present work that has focused on elucidating the precise role of the Tra protein of pIJ101 in conjugation in Streptomyces.     

Abscess forming ability of streptococcus milleri group: synergistic effect with Fusobacterium nucleatum.

The abscess forming abilities of "Streptococcus milleri" strains (Streptococcus constellatus, Streptococcus anginiosus, and Streptococcus intermedius) isolated from dentoalveolar abscesses and the synergistic effect of Fusobacterium nucleatum co-inoculated with the isolates were examined on a mouse subcutaneous abscess model. Five days after inoculation, all S. milleri strains formed abscesses, which showed less pathological spread to surrounding connective tissues than those formed by Staphylococcus aureus 209P strain and were similar to those by F. nucleatum ATCC25586. When each S. milleri strain and F. nucleatum were co-inoculated, abscess sizes and each bacterial number recovered from abscesses increased in comparison to those treated by bacterial mono-inoculation of each S. milleri strain or F. nucleatum alone. The strongest synergistic effect was observed in the combination of S. constellatus and F. nucleatum. In a time course experiment with this combination, the recovery of S. constellatus subsequently decreased after the decrement of F. nucleatum, and it appeared that the association with F. nucleatum maintained the bacterial number of S. constellatus in the abscess. The cell-free supernatant of F. nucleatum had a tendency to increase the abscess size caused by S. constellatus in this model. When S. constellatus was cultured with F. nucleatum culture supernatant in vitro, growth enhancement in the early phase was observed. Furthermore, the phagocytic killing of S. constellatus by human polymorphonuclear leukocytes (PMNs) was significantly suppressed and the PMN membranes appeared to be injured by addition of the F. nucleatum culture supernatant. These results suggest that the pathogenicity of S. milleri strains in odontogenic infections may be enhanced by the co-existence of F. nucleatum.     

Fermentative capacity of baker's yeast exposed to hyperbaric stress

Baker's yeast suspensions were incubated at different pressures (from 1 bar to 6 bar) and different gases [air, O(2) and a mixture of 8% (v/v) CO(2), 21% O(2) and N(2)]. Raising the air pressure from 1 bar to 6 bar stimulated cell growth but had no effect on leavening ability or viability of the cells. A 50% reduction of the CO(2) produced in dough occurred with 6 bar O(2) which also stopped growth. The fermentative capacity of the cells was stimulated by the cells exposure to increased CO(2) partial pressure up to 0.48 bar.     

Cassava breeding: opportunities and challenges

Although cassava is a major food crop, its scientific breeding began only recently compared with other crops. Significant progress has been achieved, particularly in Asia where cassava is used mainly for industrial processes and no major biotic constraints affect its productivity. Cassava breeding faces several limitations that need to be addressed. The heterozygous nature of the crop and parental lines used to generate new segregating progenies makes it difficult to identify parents with good breeding values. Breeding so far has been mainly based on a mass phenotypic recurrent selection. There is very little knowledge on the inheritance of traits of agronomic relevance. Several approaches have been taken to overcome the constraints in the current methodologies for the genetic improvement of cassava. Evaluations at early stages of selection allow for estimates of general combining ability effect or breeding values of parental lines. Inbreeding by sequential self-pollination facilitates the identification of useful recessive traits, either already present in the Manihot gene pool or induced by mutagenesis.     

Comparison of competitive ability between native and introduced salmonids: evidence from pairwise contests

Brown trout, Salmo trutta, and rainbow trout, Oncorhynchus mykiss, have been introduced to freshwaters in Hokkaido, Japan. Today, it is recognized that these introduced salmonids have negative impacts on native salmonids such as white-spotted charr, Salvelinus leucomaenis, and masu salmon, O. masou. In particular, interspecific competition may be an important mechanism that could contribute to the exclusion for native salmonids. In this study, experimental pairwise contests were conducted to compare interference competitive ability between native and introduced salmonids. We demonstrated that brown trout were competitively superior to white-spotted charr and masu salmon whereas rainbow trout were superior to white-spotted charr. We suggest that introduced brown trout negatively impact both white-spotted charr and masu salmon, and introduced rainbow trout negatively impact white-spotted charr.     

Genetic characterization and specific detection of beer-spoilage Lactobacillus sp. LA2 and related strains

AIMS: Lactobacillus sp. LA2 (DSM15502) and related strains (LA2 group) possess strong beer-spoilage ability. The 16S rDNA sequence of LA2 strain is virtually indistinguishable from that of L. collinoides, generally considered to be nonbeer-spoilage bacteria. The aim of this study was to identify the genetic marker to distinguish between Lactobacillus sp. LA2 group and L. collinoides and to provide a rapid means of identifying beer-spoilage strains belonging to Lactobacillus sp. LA2 group. METHODS AND RESULTS: The 16-23S rDNA intergenic spacer (ITS) regions of Lactobacillus sp. LA2 and L. collinoides JCM1123T were sequenced to identify a genetic marker to distinguish between the two groups. As a result, 300 and 500 bp ITS regions of Lactobacillus sp. LA2 were found to be almost identical with those of L. collinoides JCM1123T. Sequence comparison analysis between Lactobacillus sp. LA2 and L. collinoides JCM1123T revealed that the two contiguously located nucleotides are absent in both ITS regions of Lactobacillus sp. LA2. Based on the sequence difference, we have designed specific PCR primers with a minor modification to the primer sequence that can differentiate between beer-spoilage Lactobacillus sp. LA2 group and nonbeer-spoilage L. collinoides. CONCLUSIONS: The PCR-based method has been developed to identify Lactobacillus sp. LA2 group, providing a rapid and sensitive means of determining the beer-spoilage ability of detected bacterial strains. SIGNIFICANCE AND IMPACT OF THE STUDY: The substitution of one nucleotide, located at the third position to the 3'-end in the primer sequence, enhanced the specificity of the PCR method while retaining sufficient sensitivity. The nucleotide gap identified in this study appeared to serve as a useful genetic marker that can differentiate 12 beer-spoilage Lactobacillus sp. LA2 group strains from its close relatives that exhibit no beer-spoilage ability.
