The 1st complete mitochondrial genome in the migratory dragonfly Pantala flavescens Fabricius, 1798 (Libellulidae: Odonata).
BACKGROUND Biofilm is a fundamental bacterial survival mode which proceeds through three main generalized phases adhesion, maturation, and dispersion. Lactobacilli spp. (LB) are critical components of gut and reproductive health and are widely used probiotics. Evaluation of time-dependent mechanisms of biofilm formation is important for understanding of host-microbial interaction and development of therapeutic interventions. Time-dependent LB biofilm growth was studied in two systems large biofilm output in continuous flow system (microfermenter (M), Institute Pasteur, France) and electrical impedance-based real time label-free cell analyzer (C) (xCELLigence, ACEA Bioscience Inc., San Diego, CA). L. plantarum biofilm growth in M system was video-recorded, followed by analyses using IMARIS software (Bitplane, Oxford Instrument Company, Concord, MA, USA). Additionally, whole genome expression and analyses of attached (A) and dispersed (D) biofilm phases at 24 and 48 h were performed. RESULTS The dynamic of biofilm growth of L. plantarum was similar in both systems except for D phases. Comparison of the transcriptome of A and D phases revealed, that 121 transcripts differ between two phases at 24 h. and 35 transcripts - at 48 h. of M growth. The main pathways, down-regulated in A compared to D phases after 24 h. were transcriptional regulation, purine nucleotide biosynthesis, and L-aspartate biosynthesis, and the upregulated pathways were fatty acid and phospholipid metabolism as well as ABC transporters and purine nucleotide biosynthesis. Four LB species differed in the duration and amplitude of attachment phases, while growth phases were similar. CONCLUSION LB spp. biofilm growth and propagation area dynamic, time-dependent processes with species-specific and time specific characteristics. The dynamic of LB biofilm growth agrees with published pathophysiological data and points out that real time evaluation is an important tool in understanding growth of microbial communities.Following publication of the original article [1], it has been brought to the authors' attention that in their paper (Rodrigues et al. 2016) they reported the genome size based on 2C values (diploid genome) when it is more common to present it as 1C value.BACKGROUND Brachydactyly type A1(BDA-1) is an autosomal dominant disorder which is caused by heterozygous pathogenic variants in a specific region of the N-terminal active fragment of Indian Hedgehog (IHH). The disorder is mainly characterized by shortening or missing of the middle phalanges. In this study, Our purpose is to identify the pathogenic variations associated with BDA-1 involved in a five-generation Chinese family. METHODS A BDA-1 family with 8 affected and 14 unaffected family members was recruited. Whole exome sequencing (WES) was performed to identify the pathogenic variant in the proband, and which was later confirmed and segregated by Sanger sequencing. The significance of variants were assessed using several molecular and bioinformatics analysis methods. RESULTS We uncovered a novel heterozygous missense variant c.299A > G (p.D100G) at the mutational hotspot of IHH gene following whole-exome sequencing of a Chinese family with BDA-1. The variant co-segregated with BDA-1 in the pedigree, showed 100% penetrance for phalange phenotype with variable expressivity. CONCLUSIONS In conclusion, this study reports a five-generation Chinese family with BDA-1 due to a novel pathogenic variant (c.299A > G (p.D100G)) of IHH and expands the clinical and genetic spectrum of BDA-1.BACKGROUND Succinic semialdehyde dehydrogenase (SSADH) deficiency is a rare autosomal recessive disorder. Neuroimaging findings are commonly considered rather non-specific. To date, no neuroreceptorial brain imaging with 123I-FP-CIT(DaTScan) is known in subjects with SSADH deficiency. METHODS A 30-year-old man was referred to our attention to rule out any potential nigrostriatal dopaminergic presynaptic pathway alterations in a clinical context of a γ-hydroxybutyric aciduria. He showed impossibility to the autonomous gait, head and trunk retropulsion, lower limbs strength deficit, verbal and upper limbs motor stereotypies and irregular eye tracking. RESULTS Brain MRI depicted basal ganglia signal abnormalities. Brain SPECT with DaTSCan images showed a global significant reduction of radiotracer uptake. CONCLUSIONS The findings obtained by means of the 123I-DaTScan brain SPECT may give rise to new concerns on pathophysiological aspects of the SSADH deficiency disorder that has never been investigated before, such as the nigrostriatal dopaminergic system functionality, encouraging further investigation.

The most well known and studied phthalimide derivative (isoindoline-1,3-dione) is thalidomide, because this compound initially presented important sedative effects. This review approaches some of the recent and efficient chemical synthesis pathway to obtain phthalimide analogues. It is also presented a summary of the main biological activities of these derivatives found in the literature. Therefore, this review describes the chemical and therapeutic aspects of phthalimide derivatives.

HCV and HIV infections are specified by systemic inflammation but the inflammation process in HCV/HIV co-infection are much complicated and are not well characterized. OBJECTIVE The aim of this study was to analyze the expression of TLR-3, TLR-7, IL-10, IFN-1 (IFN-α, IFN-β), and TNF-α in HIV, HCV and HIV/HCV co-infected patients. 1 Methods Forty-five patients including HIV group (n=15), HCV group (n=15), HIV/HCV coinfection group (n=15) and healthy control group (n=15) participated. fMLP mw Peripheral blood mononuclear cells (PBMCs) were obtained. PBMC-RNA, HCV and HIV RNA were extracted from all subjects and cDNA were synthesis. The viral load analyzed by reverse transcription-quantitative PCR (RT-qPCR), as well, the expression levels of IFN-α, IFN-β, TLR-3, TLR-7, TNF, and IL-10 mRNA were quantified in PBMCs. RESULTS The levels of IFN-I, IL-10, and TNF-α were overexpressed in all patients' groups (p0.
