Mechanisms behind expansion of an invasive cyanobacterium Cylindrospermopsis raciborskii have not been fully resolved and different hypotheses, such as global warming, are suggested. In the East-Central Europe, it is widely occurring in western part of Poland but only in single locations in the East due to some limiting factors. Therefore, broad scale phytoplankton survey including 117 randomly selected lakes in Poland and Lithuania was conducted. The results showed that C. raciborskii occurred widely in western part of Poland but was absent from other regions and Lithuania except one lake...

Lily (Lilium longiflorum Thunb.) is the most representative bulb flower, and it is the third most important flower in the flower industry of South Korea after rose and chrysanthemum. To determine the efficacy of X-ray irradiation for use in quarantine processing, two species of flower thrips (Frankliniella intonsa (Trybom) and Frankliniella occidentalis (Pergande)) were placed in the top, middle, and bottom locations of lily boxes and irradiated with different X-ray doses. After irradiation with an X-ray dose of 150 Gy, the egg hatching of the two flower thrips was completely inhibited at every location in the lily boxes, and the irradiated F...

A new bacterial isolate, Paenibacillus sp. OSY-N, showed potent antimicrobial activity against Gram-negative and Gram-positive bacteria. Antimicrobials produced by this strain were purified by reverse-phase high performance liquid chromatography (HPLC). Structural analysis, using mass spectrometry (MS), of a single active HPLC fraction revealed two known cyclic lipopeptides, BMY-28160 and permetin A, a new cyclic lipopeptide, and the linear counterparts of these cyclic compounds. The latter were designated as paenipeptin A, B and C, respectively...

Ongoing payment reform in dialysis necessitates better patient outcomes and lower costs. Suggested improvements to processes of care for maintenance dialysis patients are abundant; however, their impact on patient-important outcomes is unclear. This systematic review included comparative randomized controlled trials or observational studies with no restriction on language, published from 2000 to 2014, involving at least 5 adult dialysis patients who received a minimum of 6 months of follow-up. The effect size was pooled and stratified by intervention strategy (multidisciplinary care [MDC], home dialysis, alternate dialysis settings, and electronic health record implementation)...

REVIEW
Andrew M Jones, Anni Vanhatalo
The curvilinear relationship between power output and the time for which it can be sustained is a fundamental and well-known feature of high-intensity exercise performance. This relationship 'levels off' at a 'critical power' (CP) that separates power outputs that can be sustained with stable values of, for example, muscle phosphocreatine, blood lactate, and pulmonary oxygen uptake ([Formula: see text]), from power outputs where these variables change continuously with time until their respective minimum and maximum values are reached and exercise intolerance occurs...

Jamun fruit comprises of seed and thick pulp. The pectin-protein bond of the thick pulp creates difficulty in making juice. Clear Jamun juice is not available in the market, so there is a need for extraction of juice with maximum yield. The goal of this research is to obtain high yield of clarified juice with the help of Pectinase (Aspergillus aculeatus) enzyme. The study was conducted at different enzyme concentration (0.01-0.1%), time duration (40-120 min), and temperature (30-50 °C). Various physical and chemical parameters, such as yield, turbidity, viscosity, clarity, colour, polyphenol, protein, TSS, and total solid, were measured as dependent variables...

BACKGROUND: Given the neurological morbidity and poor prognosis associated with brain metastases, it is critical to deliver appropriate therapy while remaining mindful of patient quality of life (QOL). For many patients, stereotactic radiosurgery (SRS) effectively controls intracranial disease, but QOL outcomes have not been characterized. OBJECTIVE: To determine the effect of number of brain metastases upon QOL preservation following SRS. METHODS: The EuroQol 5 Dimensions questionnaire (EQ-5D) and Patient Health Questionnaire 9 instruments were prospectively collected from a cohort of patients undergoing SRS for brain metastasis between 2008 and 2015...

BACKGROUND: A rising number of female-affirmed transgender adolescents are being treated with gonadotropin-releasing hormone analogues and subsequently cross-sex hormones at early or mid-puberty, with vaginoplasty as the presumed final step in their physical transition. But, despite the minimum age of 18 years defining eligibility to undergo this irreversible procedure, anecdotal reports have shown that vaginoplasties are being performed on minors by surgeons in the United States, thereby contravening the World Professional Association for Transgender Health (WPATH) standards of care (SOC)...

Number of incurable diseases associated with neurodegenerative syndromes like Alzheimer's, and Parkinson's, are owing to protein aggregation which leads to amyloid fibril formation. In vitro, such fibrillation depends on concentration, temperature, pH, ionic strength, organic solvents, agitation, and stirring, which play a crucial role in understanding the mechanism of fibrillation as well as to identify potential inhibitors for fibrillation. Although these parameters were considered, the precise repeatability of amyloid fibrillation kinetics between laboratories remains challenging...

BACKGROUND: Chronic obstructive pulmonary disease (COPD) (commonly referred to as chronic bronchitis and emphysema) is a chronic lung condition characterised by the inflammation of airways and irreversible destruction of pulmonary tissue leading to progressively worsening dyspnoea. It is a leading international cause of disability and death in adults. Evidence suggests that there is an increased prevalence of anxiety disorders in people with COPD. The severity of anxiety has been shown to correlate with the severity of COPD, however anxiety can occur with all stages of COPD severity...

The reproductive biology of the white grunt Haemulon plumierii was studied from 360 individuals obtained from artisanal fisheries landings in the Abrolhos Bank, Brazil, between August 2010 and March 2012. The overall sex-ratio did not differ significantly from 1:1, although males predominated in larger size classes. β-Binomial modelling of historical sex-ratio data indicated that the catch rate of females has increased in recent years. Females reached maturity at a smaller total length (LT ; 214 mm) than males (235 mm LT ) and the LT at which 50% of all individuals are mature (L50 ) was 220 mm, corresponding to 41·5% of the maximum recorded LT ...

AIMS: In-stent restenosis (ISR) is an important cause of DES failure and target vessel revascularization. We evaluated differences between early and late-presenting restenosis in second-generation drug-eluting stents (DES) using optical coherence tomography (OCT). METHODS AND RESULTS: Overall, 171 cases of second-generation DES ISR with a follow-up OCT minimum lumen area <3.0mm2 were included; 33.3% of patients (n=57) had early ISR; and 67.7% (n=114) had late ISR (duration from stent implantation >1 year)...

OBJECTIVE/BACKGROUND: Mycobacterium cosmeticum, first described in 2004, was recovered from a patient undergoing a cosmetic procedure. Subsequently, this species was associated with an outbreak in a nail salon. In all cases, the isolates were susceptible to all antibiotics tested. Recently, however, we recovered a strain of M. cosmeticum from the Chesapeake Bay, resistant to 11 of 14 antimicrobials. The objective of this work was to present our findings on the resistance and susceptibility of this isolate to various antibiotics...

BACKGROUND: Biological invasions have become a major threat to biodiversity, and identifying determinants underlying success at different stages of the invasion process is essential for both prevention management and testing ecological theories. To investigate variables associated with different stages of the invasion process in a local region such as Taiwan, potential problems using traditional parametric analyses include too many variables of different data types (nominal, ordinal, and interval) and a relatively small data set with too many missing values...

Boolean network (BN) is a popular mathematical model for revealing the behaviour of a genetic regulatory network. Furthermore, observability, an important network feature, plays a significant role in understanding the underlying network. Several studies have been done on analysis of observability of BNs and complex networks. However, the observability of attractor cycles, which can serve as biomarker detection, has not yet been addressed in the literature. This is an important, interesting and challenging problem that deserves a detailed study...

Brian W Schulz
Minimum toe clearance (MTC) is thought to quantify the risk of the toe contacting the ground during the swing phase of gait and initiating a trip, but there are methodological issues with this measure and the risk of trip-related falls has been shown to also be associated with gait speed and dynamic stability. This paper proposes and evaluates a new measure, trip risk integral (TRI), that circumvents many issues with MTC as typically calculated at a single point by considering minimum foot clearance across the entire swing phase and taking into account dynamic stability to estimate risk of falling due to a trip rather than risk of the foot contacting the floor...
