Aicardi-Goutieres syndrome(AGS)is a systemic inflammatory disorder caused by mutations in any one of the nine different genes,whose deficiency provokes a type I(interferon)IFN response probably central to pathogenesis.^(1) ADAR1,one of the genes mutated in AGS(AGS6),encodes for an enzyme that belongs to the ADAR family(ADAR1,ADAR2,and ADAR3)that catalyzes the conversion of adenosine to inosine within double-stranded RNAs(dsRNAs)(RNA editing A-to-1).

A General Approach to L(h,k)-Label Interconnection Networks

引用

Journal of Computer Science & Technology 2008年第4期23卷 652-659页

作者： Tiziana Calamoneri Saverio Caminiti Rossella Petreschi Department of Computer Science Sapienza University of Rome

Given two non-negative integers h and k, an L（h, k）-labeling of a graph G = （V, E） is a function from the set V to a set of colors, such that adjacent nodes take colors at distance at least h, and nodes at distance 2 take colors at distance at least k. The aim of the L（h, k）-labeling problem is to minimize the greatest used color. Since the decisional version of this problem is NP-complete, it is important to investigate particular classes of graphs for which the problem can be efficiently solved. It is well known that the most common interconnection topologies, such as Butterfly-like, Beneg, CCC, Trivalent Cayley networks, are all characterized by a similar structure： they have nodes organized as a matrix and connections are divided into layers. So we naturally introduce a new class of graphs, called （l × n）-multistage graphs, containing the most common interconnection topologies, on which we study the L（h, k）-labeling. A general algorithm for L（h, k）-labeling these graphs is presented, and from this method an efficient L（2, 1）-labeling for Butterfly and CCC networks is derived. Finally we describe a possible generalization of our approach.

Calcium-sensitive protein MLC1 as a possible modulator of the astrocyte functional state

Astrocytes,the main population of glial cells in the central nervous system(CNS),exert essential tasks for the control of brain tissue homeostasis,supporting neuron and other glial cell activity from the developmental stage to adult *** maintain the optimal functionality of the brain,astroglial cells are particularly committed to reacting to every change in tissue homeostatic conditions,from mild modifications of the physiological environment,a process called astrocyte activation,to the more severe alterations occurring in pathological situations causing astrocyte reactivity or reactive astrogliosis(Escartin et al.,2021).During these reactive states,astrocytes mount an active,progressive response encompassing morphological,molecular,and interactional remodeling,leading to the acquisition of new functions and the loss of others,whose intensity,duration,and reversibility are dependent on the nature of the stimulus and regulated in a context-specific manner.

Human semen hyperviscosity： prevalence, pathogenesis and therapeutic aspects

引用

Asian Journal of Andrology 2009年第5期11卷 609-615,I0004页

The aims of this study were （a） to determine the prevalence of subjects with semen hyperviscosity （SHV） in a large population of male partners of subfertile couples; （b） to identify any correlation between SHV and infections or inflammation of the genital tract; （c） to assess the effects of therapeutic approaches for treating SHV; and （d） to assess sperm kinetic parameters after successful treatment of SHV. A retrospective study of 1 833 male partners of subfertile couples was conducted. Next, clinical, seminal, bacteriological and ultrasound studies involving 52 subjects suffering from SHV were performed, and the SHV was classified as being mild （length of thread 〉 2 cm and ≤4 cm）, moderate （〉 4 cm and ≤ 6 cm） or severe （〉 6 cm）. The prevalence of SHV was observed in 26.2% （480） of the subjects, with 13.2% suffering from mild, 6.6% from moderate and 6.4% from severe SHV. Treatment was completely successful in only 27 subjects （52.0%）, primarily in those who had mild basal SHV with a positive semen culture. In these subjects, progressive motility percentage, straight line velocity and linearity were significantly higher than pre-treatment levels. SHV is often found in subjects with subfertility. Pathogenesis was strictly related to infective/inflammatory factors in only 48.0% of cases; therefore, it is possible that biochemical, enzymatic or genetic factors have a role in this condition.

Background The role of human bocavirus (HBoV) as a respiratory pathogen has not been fulfilled *** aimed to describe clinical and serological characteristics of children with HBoV hospitalized for acute respiratory tract infection and to evaluate whether differences occur between HBoV alone and in *** We retrospectively reviewed data from 60 children (median age of 6.2 months,range 0.6-70.9) hospitalized for acute respiratory symptoms,with HBoV detected from a respiratory sample,using a reverse transcriptase-PCR for 14 respiratory viruses (including respiratory syncytial virus (RSV),influenza virus A and B,human coronavirus OC43,229E,NL-63 and HUK1,adenovirus,rhinovirus,parainfluenza virus 1-3,and human metapneumovirus).Results HBoV was detected alone in 29 (48.3%) patients,while in co-infection with other viruses in 31 patients (51.7%),with a peak between December and *** the 60 patients,34 were bronchiolitis,19 wheezing,3 pneumonia,2 upper respiratory tract infection,and 2 whooping *** children (11.6%) required admission to the paediatric intensive care unit (PICU) for respiratory *** differences was observed in age,family history for atopy and/or asthma,clinical presentations,chest X-ray,or laboratory findings in children with HBoV alone *** viral *** was the most frequently co-detected virus (61.3%).When compared with HBoV detection alone,the co-detection of RSV and HBoV was associated with male sex (P=0.013),younger age (P=0.01),and lower blood neutrophil count (P=0.032).Conclusions HBoV can be detected alone and in co-infection respiratory samples of children with an acute respiratory tract infection.A cause-effect relationship between HBoV and respiratory infection is not clear,so further studies are needed to clarify this point.

ABCB1 and ABCB19 auxin transporters have synergistic effects on early and late Arabidopsis anther development

引用

Journal of Integrative Plant Biology 2015年第12期57卷 1089-1098页

Arabidopsis abcbl abcb19 double mutants defective in the auxin transporters ABCB1/PGP1 and ABCB19/PGP19 are altered in stamen elongation, anther dehiscence and pollen maturation. To assess the contribution of these transporters to stamen development we performed phenotypic, histological analyses, and in situ hybridizations on abcbl and abcbl9 single mutant flowers. We found that pollen maturation and anther dehiscence are precocious in the abcbl but not in the abcb19 mutant. Accordingly, endothecium ligniflcation is altered only in abcbl anthers. Both abcbl and abcb1 abcb19 stamens also show altered early development, with asynchronous anther Iocules and a multilayer tapetum. DAPI staining showed that the timing of meiosis is asynchronous in abcbl abcb19 anther Iocules, while only a small percentage of pollen grains are non- viable according to Alexander＇s staining. In agreement, TAM （TARDY ASYNCHRONOUS MEIOSIS）, as well as BAM2 （BARELY ANY MERISTEM）involved in tapetal cell development--areoverexpressed in abcbl abcb19 young flower buds. Corre- spondingly, ABCB1 and ABCB19 mRNA localization supports the observed phenotypes of abcbl and abcbl abcb19 mutant anthers. In conclusion, we provide evidence that auxin transport plays a significant role both in early and late stamen development： ABCB1 plays a major role during anther development, while ABCB19 has a synergistic role.
