The microbiome of freshwater sponges is rarely studied, and not a single novel bacterial species has been isolated and subsequently characterized from a freshwater sponge to date. A previous study showed that 14.4% of the microbiome from Ephydatia fluviatilis belong to the phylum Planctomycetes. Therefore, we sampled an Ephydatia sponge from a freshwater lake and employed enrichment techniques targeting bacteria from the phylum Planctomycetes. The obtained strain spb1 was subject to genomic and phenomic cha...
: The aim of the study was to verify the agreement between preplanned and executed pacing during a 3-km race and determine whether adjustments are mediated by the rating of perceived exertion (RPE). : Thirteen young runners (eight males and five females, 17.5 ± 2.1 and 17.0 ± 1.6 years old, respectively) with national and international experience participated in the study. Before the simulated competition, the athletes informed of their preplanned pacing for the distance through a dashboard with the ...
Cadmium (Cd) contamination is becoming a significant environmental concern due to its persistency in soil. In the subsurface, the fate and transport of Cd are significantly affected by the presence of organic carriers, including bacteria, which are ubiquitous. In this research, facilitated Cd transport by four different bacterial strains in zeolite was investigated by column experiments under three different Cd introduction scenarios (i.e., a Cd and bacteria mixture, Cd and bacteria introduced separately bu...
Tailed bacteriophages (phages) are one of the most abundant life forms on Earth. They encode highly efficient molecular machines to infect bacteria, but the initial interactions between a phage and a bacterium that then lead to irreversible virus attachment and infection are poorly understood. This information is critically needed to engineer machines with novel host specificities in order to combat antibiotic resistance, a major threat to global health today. The tailed phage T4 encodes a specialized devic...
Mycobacteriophages are viruses specific to mycobacteria that have gained attention as alternative therapeutic strategies for treating antibiotic-resistant infections. Mycobacteriophages are highly diverse and have been grouped into 29 clusters, 63 sub-clusters and 10 singletons based on the genome sequence. Here, we annotate the genome of PDRPxv, a lytic mycobacteriophage isolated from New Delhi; it belongs to the Siphoviridae family as determined by transmission electron microscopy. This phage survives at ...
AIDs may disproportionately impact specific racial groups, but autoimmune (AID) prevalence information by minority racial group is sparse for many AIDs. The objective of this analysis was to supplement previously published AID prevalence rates by providing information on race rate ratios (minority race populations compared to Caucasian populations) in the United States. Preliminary to estimating race rate ratios, contemporary US-specific, health care utilization-based AID prevalence rates and female-to-male...
Alterations in mineral metabolism, such as high phosphorus, high parathyroid hormone (PTH) and high fibroblast growth factor-23 (FGF-23) have been identified as potential risk factors for heart failure (HF). Important differences in the prevalence of mineral metabolism abnormalities and in the risk of HF have been reported across race/ethnic groups. In this study, we evaluated whether the associations of mineral metabolism markers with HF differed by race/ethnicity.
We report the identification and characterization of a bacteriophage λ-encoded protein, NinH. Sequence homology suggests similarity between NinH and Fis, a bacterial nucleoid-associated protein involved in numerous DNA topology manipulations, including chromosome condensation, transcriptional regulation and phage site-specific recombination. We find that NinH functions as a homodimer and is able to bind and bend double-stranded DNA in vitro. Furthermore, NinH shows a preference for a 15 bp signature sequen...
The Geographic Mosaic Theory of Coevolution (GMTC) predicts that coevolutionary arms races will vary over time and space because of the diverse ecological settings and population histories of interacting species across the landscape. Thus, understanding coevolution may require investigating broad sets of populations sampled across the range of the interaction. In addition, comparing coevolutionary dynamics between similar systems may reveal the importance of specific factors that structure coevolution. Here...
Klebsiella pneumoniae is an important emerging pathogen of humans and animals which may lead to major clinical implications including mortality. Moreover the increased use of antibiotics has promoted emergence of carbapenem resistant strains and extended spectrum β-lactamase producers (ESBLs) of K. pneumoniae. Recently, phage therapy has gained momentum as a conceivable alternative against emerging antibiotic resistance.
To study the effect of prolonged complex decongestive therapy (CDT) on lymphedema in arms without a subcutaneous echo-free space on subcutaneous tissue ultrasonography.
Neurosurgery is consistently one of the most competitive specialties for resident applicants. The emphasis on research in neurosurgery has led to an increasing number of publications by applicants seeking a successful residency match. The authors sought to produce a comprehensive analysis of research produced by neurosurgical applicants and to establish baseline data of neurosurgery applicant research productivity given the increased emphasis on research output for successful residency match.
Plasmodium knowlesi, the fifth human malaria parasite, has caused mortality in humans. We aimed to identify P. knowlesi novel binding peptides through a random linear dodecapeptide phage display targeting the 19-kDa fragment of Merozoite Surface Protein-1 protein.
Oral VRL offers easier administration, better quality of life, and cost saving. This study aimed to evaluate the treatment efficacy in terms of tumor response of the two formulations of vinorelbine (VRL, oral and IV) in combination with epirubicin (EPI); and the effect of EPI co-administration on VRL pharmacokinetics (PK) in Chinese patients with metastatic breast cancer (MBC) using a phase 2, open label, randomized trial. Patients were aged 18-70 years, had histologically confirmed MBC, Karnofsky Performa...
Biomechanical investigations examining shoulder function commonly observe a high degree of inter-individual variability in muscle activity and kinematic patterns during static and dynamic upper extremity exertions. Substantial differences in musculoskeletal geometry between individuals can alter muscle moment arms and lines of action that, theoretically, alter muscle activity and shoulder kinematics. The purposes of this research were to: (i) quantify model-predicted functional roles (moment arms, lines of ...
Recent literature has shown significant differences in meningioma incidence between different races, but minimal conclusive data exists on the role of race and ethnicity in overall survival for patients with high-grade intracranial meningioma. We conducted a systematic review to investigate the impact of race and ethnicity on survival in patients with high-grade intracranial meningioma.
The discovery of Sodium-Glucose co-transporter-2 (SGLT2) inhibitors had rewritten the treatment of diabetes mellitus with an impressive fall in incidence of death and associated complications.
Oral malodor is a common condition caused by some Gram-negative oral bacteria, among which are the 3 red complex bacteria (RCB). The present study investigated the effectiveness of the Ultrasound Tongue Scraper (UTS) to disrupt the structural morphology of the bacteria and their biofilm.
To investigate whether participation in the Trans Europe Foot Race 2009 (TEFR), an ultramarathon race held over 64 consecutive days and 4486 km, led to changes in cardiac structure and function.
Hidradenitis suppurativa (HS) is an often-debilitating disease characterized by chronic and recurrent painful nodules, abscesses, and sinus tracts affecting the intertriginous areas. Despite evidence in the literature of varying prevalence of HS among different racial and ethnic groups, no studies have evaluated the overall generalizability of clinical trial results considering the increased prevalence of HS among African American populations. Additionally, there is a paucity of data exploring the distribut...
An observed disparity in population-scale data are a larger number of males among preterm births (PTBs). We investigated spontaneous PTB risk among women of various race/ethnic groups in combination with infants' sex.
There have been few large studies involving multiethnic cohorts of patients treated with anterior cruciate ligament reconstruction (ACLR), and therefore, little is known about the role that race/ethnicity may play in the differential risk of undergoing revision surgery following primary ACLR. The purpose of this study was to evaluate whether differences exist by race/ethnicity in the risk of undergoing the elective procedure of aseptic revision in a universally insured cohort of patients who had undergone A...
Researchers typically identify health disparities using self-reported race/ethnicity, a measure identifying individuals' social and cultural affiliations. In this study, we use data from Waves 1, 3, and 4 of Add Health to examine health disparities by interviewer-ascribed skin color, a measure capturing the perceptions of race/ethnicity ascribed to individuals by others. Individuals with darker skin tones may face greater exposure to serious stressors such as perceived discrimination, poverty, and economic ...
