This includes their de novo biosynthesis from renewable resources, biotransformations in single- and biphasic fermentation setups, metabolic funneling of lignin-derived aromatics, and the upcycling of aromatic monomers from plastic waste streams. Additionally, this review provides insights into unique features of Pseudomonads that make them exceptional hosts for aromatics biotechnology and discusses engineering strategies.The dynamic biogeography of glacial refugia may cause complex patterns of genetic admixture between parapatric taxa, which in turn can mislead their systematics, diversity, and distributions. We investigated this issue for green toads (Bufotes) inhabiting the circum-Aegean region, a biodiversity hotspot of the Eastern Mediterranean. A previous phylogeographic study based on mitochondrial and microsatellite loci identified the hybrid zone between the European (viridis) and Anatolian (sitibundus) lineages of B. viridis all over the Balkan Peninsula, but subsequent range-wide genomic analyses (>1000 SNPs) located this transition in Turkey, a thousand kilometers eastwards. In order to clarify the diversity and taxonomy of the circum-Aegean populations, we reconciled these conflicting findings by integrating previous data with pure sitibundus individuals. Our results confirmed that the viridis/sitibundus hybrid zone extends in Western Anatolia, but that southeastern European populations feature cytonuclear discordances and a high and structured microsatellite diversity. This remarkable situation may stem from a massive geographic displacement of the hybrid zone during the last glacial fluctuations, an underappreciated yet seemingly common feature among the herpetofauna of the region. Our study thus contributes to the rising view that mitochondrial DNA can be a poor predictor of current phylogeographic structure, hence the need for genomic data, especially for narrowly distributed taxa. Finally, the analyses unambiguously support the distinction of a micro-endemic clade of green toads unique to some Cyclades islands, for which we provide a formal taxonomic description.Concerning that the residues of photosensitizers (PS) may cause serious side effects under light, it is of great significant to timely switch-off PS after photodynamic therapy (PDT). Herein, we proposed a supramolecular strategy to regulate the activity of PS, fabricating a supramolecular PS with improved reactive oxygen species (ROS) generation efficiency and accelerated self-degradation ability. During PDT treatment, the supramolecular PS exhibited good therapeutic efficiency as well as reduced dark toxicity. Moreover, the supramolecular PS could be degraded by ROS generated by itself and lose its PDT activities once PDT treatment finished. In this way, the side effects of PDT can be reduced without sacrificing the therapeutic efficiency. This work provides a novel strategy for smarter PDT beacon to further improve the safety of PDT treatment.Long non-coding RNAs (lncRNAs) are poorly understood in insects. In this study, we performed genome-wide analysis of lncRNAs in Tribolium castaneum by RNA-seq. In total, 4516 lncRNA transcripts corresponding to 3917 genes were identified from late embryos, early larvae, late larvae, early pupae, late pupae and early adults of T. castaneum, including 3152 novel lncRNAs and 1364 known lncRNAs. These lncRNAs have few exons and transcripts, and are short in length. During development, they exhibited nine different expression patterns. Functionally, they can act either by targeting messenger RNAs (1813 lncRNAs) and lncRNAs (45 lncRNAs) or as micro RNA (miRNA) precursors (46 lncRNAs). LncRNAs were observed to target the metabolic enzymes of glycolysis, TCA cycle and amino acids, demonstrating that lncRNAs control metabolism by regulating metabolic enzymes. Moreover, lncRNAs were shown to participate in cell differentiation and development via their targets. As miRNA precursors, lncRNAs could participate in the ecdysone signaling pathway. This study provides comprehensive information for lncRNAs of T. castaneum, and will promote functional analysis and target identification of lncRNAs in the insect.Pulmonary infection by Mycoplasma hominis (M hominis) in lung transplant (LTx) recipients is an uncommon yet potentially severe complication. Linrodostat cost Bronchial dehiscence in the context of M hominis infection has not been previously reported. In this report, we discuss a case of donor-derived M hominis infection in a LTx recipient with bilateral bronchial anastomoses dehiscence and stenosis. The infection was managed using a multidisciplinary approach repeat surgical revision of the necrotic anastomosis; targeted antibiotic therapy with the combination of oral and inhaled fluoroquinolones, and oral doxycycline and continuous ventilatory support. Response to therapy was monitored through repeat bronchoscopy and serial quantitative PCR assays for M hominis in bronchoalveolar lavage and aspiration. The rare nature of M hominis infection after LTx, its difficult detection in conventional cultures and innate resistance to beta-lactams make diagnosis and timely treatment of this organism challenging. We recommend that transplant centers have a low threshold for screening for Mycoplasma infection, particularly in patients with unsatisfactory postoperative course and little response to broad-spectrum antimicrobial and antifungal coverage. Monitoring with PCR may help to adapt the duration of antibiotic therapy.HIV-1 viral load (VL) testing is a crucial element in providing an antiretroviral treatment monitoring program. The success of these programs depends on the availability and quality of the VL testing services. There are several pre-analytic factors which can affect the quality of VL testing. Many of the challenges faced by resource-limited countries result in a compromise of specimen integrity, thus limiting widespread access to VL monitoring. The various logistic and financial challenges that exist are not insurmountable and several innovative solutions currently exist to overcome these barriers to providing widespread VL testing. This review summarizes the VL testing challenges in resource-limited settings and provides an overview of potential solutions including testing dried blood spots, dried plasma spots, plasma separation cards and the use of point of care tests.
