Host defense peptides, also known as antimicrobial peptides, are key elements of innate host defense. One host defense peptide with well-characterized antimicrobial activity is the human cathelicidin, LL-37. LL-37 has been shown to be upregulated at sites of infection and inflammation and is regarded as one of the primary innate defense molecules against bacterial and viral infection. Human exposure to combustion-derived or engineered nanoparticles is of increasing concern, and the implications of nanomaterial exposure on the human immune response is poorly understood...

Brett S Younginger, Daniel J Ballhorn
PREMISE OF THE STUDY: Fungal endophytes have been shown to colonize all land plants, yet surprisingly little attention has been given to their community composition in ferns. We examined the diversity and temporal turnover of fungal endophytes in foliar tissue of the temperate western sword fern, Polystichum munitum, comparing taxa in newly emerged leaflets and in the same fronds after 1 mo of exposure in the field. METHODS: Utilizing next-generation sequencing, we sampled pinnae from P...

PREMISE OF THE STUDY: Although asexual taxa are generally seen as evolutionary dead ends, asexuality appears to provide a short-term benefit in some taxa, including a wider geographic distribution compared to sexual relatives. However, this may be an illusion created by multiple, morphologically cryptic, asexual lineages, each occupying a relatively small area. In this study we investigate the role of multiple lineages in the biogeography of Myriopteris gracilis Fée (Pteridaceae), a North American apomictic triploid fern species with a particularly large range...

BACKGROUND: Adiantum philippense (AP) is a pteridophyte that shows antihyperglycemic activity in vivo diabetic model, but the mechanism of action is unknown. OBJECTIVE: AP was found to play a pivotal role in minimizing the high blood glucose in alloxan-induced diabetic rats. Simultaneously, it was observed that it could maintain the normal lipid profile even in diabetic condition. To investigate its insulin-like activity along with its inhibitory role on adipocyte differentiation became the objective of our present study...

Sudden infant death syndrome (SIDS) remains the leading cause of postneonatal mortality in the United States, despite reduction in rates of more than 50% since the initiation of the "Back to Sleep" (now called "Safe to Sleep") campaign in 1994. In recent years, the rate of decline in SIDS deaths has plateaued, even with the ongoing educational efforts that promote safe sleep and other risk reduction measures. The 2016 American Academy of Pediatrics guidelines for reducing the risk of SIDS focus heavily on sleep practices, bedding, and location, but also include factors that often receive less attention (ie, prenatal care, maternal smoking, alcohol and drug use, and childhood vaccinations)...

Enzootic bovine haematuria (EBH) in cattle occurs in upland areas of the world. In India, the disease is present in isolated pockets in the Himalayas and in the Nilgiri Hills. The variation in the disease incidence has been attributed to different environmental conditions and animal rearing practices followed in the different regions. The aim of the study was to conduct field surveys in parts of EBH endemic regions of Himachal Pradesh, a north-western Himalayan state of India. Out of the total 103 plant samples collected, a total of 95 samples were identified as ferns...

Culture-independent molecular surveys of plant root microbiomes indicate that soil type generally has a stronger influence on microbial communities than host phylogeny. However, these studies have mostly focussed on model plants and crops. Here, we examine the root microbiomes of multiple plant phyla including lycopods, ferns, gymnosperms, and angiosperms across a soil chronosequence using 16S rRNA gene amplicon profiling. We confirm that soil type is the primary determinant of root-associated bacterial community composition, but also observe a significant correlation with plant phylogeny...

Herein, we describe three advanced techniques for cathodoluminescence (CL) spectroscopy that have recently been developed in our laboratories. The first is a new method to accurately determine the CL-efficiency of thin layers of phosphor powders. When a wide band phosphor with a band gap (Eg > 5 eV) is bombarded with electrons, charging of the phosphor particles will occur, which eventually leads to erroneous results in the determination of the luminous efficacy. To overcome this problem of charging, a comparison method has been developed, which enables accurate measurement of the current density of the electron beam...

BACKGROUND: Early HIV diagnosis reduces morbidity, mortality, the probability of onward transmission, and their associated costs, but might increase cost because of earlier initiation of antiretroviral treatment (ART). We investigated this trade-off by estimating the cost-effectiveness of HIV screening in primary care. METHODS: We modelled the effect of the four-times higher diagnosis rate observed in the intervention arm of the RHIVA2 randomised controlled trial done in Hackney, London (UK), a borough with high HIV prevalence (≥0·2% adult prevalence)...

The C3-symmetric uranium(iv) and cerium(iv) complexes Me3SiOM(OAr(P))3, M = U (1), Ce (2), OAr(P) = OC6H2-6-(t)Bu-4-Me-2-PPh2, have been prepared and the difference between these 4f and 5f congeners as initiators for the ring opening polymerisation (ROP) of l-lactide is compared. The poorly controlled reactivity of the homoleptic analogue U(OAr(P))4 (3) demonstrates the importance of the M-OSiMe3 initiating group. The incorporation of a nickel atom in 1 to form the U-Ni heterobimetallic complex Me3SiOU(OAr(P))3Ni (4) may be the first example of the use of the inverse trans influence to switch the reactivity of a complex...

Human rhinoviruses (HRVs) are the most common cause of viral respiratory tract infections, and are associated with significant morbidity and mortality in immunocompromised individuals and patients with pre-existing pulmonary conditions. The therapeutic options available are extremely limited and therefore novel therapeutics for HRV infections are of significant interest. Cathelicidins have been shown to have potent antiviral activity against a range of pathogens and are known to be key immunomodulatory mediators during infection...

Although vitamin D deficiency is known to be a risk factor for some psychological disorders, there have been few studies on the effects of vitamin D supplementation on their symptoms. Depression and aggression are common mental disorders and are associated with disability and disease burden. We aimed to evaluate the effectiveness of high-dose vitamin D supplementation on depression and aggression scores in adolescent girls. Nine hundred forty adolescent girls received vitamin D3 at a dose of 50,000 IU/week for 9 weeks...

PREMISE OF THE STUDY: Comparative analyses of plastid genomes have suggested that gene order and content are relatively stable across the main groups of land plants, with significant changes rarely reported. We examine plastome organization and RNA editing in ferns and report changes that add valuable information on plastome evolution in land plants. METHODS: Using next-generation sequencing methods, we fully sequenced plastomes from three species of Schizaeaceae, and compared their plastomes with other groups of land plants to study changes in gene composition, plastome architecture, and putative RNA editing sites...

The transcription of photosynthesis genes encoded by the plastid genome is mainly mediated by a prokaryotic-type RNA polymerase called plastid-encoded plastid RNA polymerase (PEP). Standard PEP-dependent promoters resemble bacterial sigma-70-type promoters containing the so-called -10 and -35 elements. On the other hand, an unusual light- and stress-responsive promoter (psbD LRP) that is regulated by a 19-bp AAG-box immediately upstream of the -35 element has been mapped upstream of the psbD-psbC operon in some angiosperms...

Despite the success of safe sleep campaigns and the progress in understanding risk factors, the rate of reduction in the cases of sudden infant death syndrome has now slowed and it remains a leading cause of postneonatal mortality in many developed countries. Strategic action is needed to tackle this problem and it is now vital to identify how the sudden infant death research community may best target its efforts. The Global Action and Prioritization of Sudden Infant Death Project was an international consensus process that aimed to define and direct future research by investigating the priorities of expert and lay members of the sudden unexpected infant death (SUID) community across countries...
