The selective removal of B800 bacteriochlorophyll (BChl) a from light-harvesting complex 2 (LH2) in purple photosynthetic bacteria is a clue about elucidation of the mechanism for the transfer of energy from these pigments to B850 BChl a and their roles in the LH2 protein structure. We demonstrated that the kinetics of the removal of B800 BChl a from two representative LH2 proteins derived from Phaeospirillum molischianum and Rhodoblastus acidophilus differed significantly, in contrast to the calculated binding enthalpy...

The metameric structure in vertebrates is based on the periodic formation of somites from the anterior end of the presomitic mesoderm (PSM). The segmentation boundary is defined by the Tbx6 expression domain, whose anterior limit is determined by Tbx6 protein destabilization via Ripply2. However, the molecular mechanism of this process is poorly understood. Here, we show that Ripply2 directly binds to Tbx6 in cultured cells without changing the stability of Tbx6, indicating an unknown mechanism for Tbx6 degradation in vivo...

Targeted interventions have been delivered to neighbors of cholera cases in major epidemic responses globally despite limited evidence for the impact of such targeting. Using data from urban epidemics in Chad and D.R. Congo we estimate the extent of spatiotemporal zones of increased cholera risk around cases. In both cities, we found zones of increased risk of at least 200-meters during the 5-days immediately following case presentation to a clinic. Risk was highest for those living closest to cases and diminished in time and space similarly across settings...

In this piece we discuss and reflect on the conclusion of the Theranos saga in the light of its fraud conviction. Theranos (founded in 2003 by Elizabeth Holmes) was supposed to disrupt the diagnostic testing industry by developing technology which could perform dozens of tests using a tiny amount of blood from a finger-prick. As a result, Ms. Holmes rose to fame, becoming the world's youngest female self-made billionaire and was plastered across magazine covers. However, in 2014, Theranos began to fall apart following increasingly damaging revelations regarding its lack of expertise, technology, framework, extreme secrecy and inaccurate test results...

Unknown 15 years ago, PCSK9 (proprotein convertase subtilisin/kexin type 9) is now common parlance among scientists and clinicians interested in prevention and treatment of atherosclerotic cardiovascular disease. What makes this story so special is not its recent discovery nor the fact that it uncovered previously unknown biology but rather that these important scientific insights have been translated into an effective medical therapy in record time. Indeed, the translation of this discovery to novel therapeutic serves as one of the best examples of how genetic insights can be leveraged into intelligent target drug discovery...

PURPOSE OF REVIEW: In the current era of implantable cardioverter-defibrillator procedures, the decision of whether or not to perform defibrillation threshold testing at the time of implantation is now less of a clinical conundrum. In this paper, we summarize this current practice, beginning with the physiology of defibrillation, followed by a review of the salient data, and discussion of specific situations where defibrillation threshold testing remains a clinical consideration. RECENT FINDINGS: Two prospective randomized trials demonstrated no mortality difference and no overall complication rate difference between patients who underwent defibrillation testing at implant compared with patients who underwent no defibrillation testing...

OBJECT: Measurements of quantitative blood flow are crucial during brain vascular surgery. Indocyanine green video angiography (ICG-VAG) is an accepted method of blood flow visualization. However, quantitative techniques have not been established. Thus, the aim of this study was to further develop ICG analysis in visualization of intraoperative flow change. METHODS: We conducted basic experiments and clinical investigations to establish a relationship between ICG-VAG and measured blood flow...

Background: As Myanmar progresses towards lymphatic filariasis (LF) elimination, it is important to know how well the anti-filarial activities have performed. The present study was conducted to study the implementation of the key anti-filarial activities and their impact on key indicators of LF transmission. Methods: A secondary analysis of aggregate program data on the anti-filarial activities was conducted in four endemic state/regions of Myanmar receiving at least six mass drug administration (MDA) rounds during 2001-2016...

The purpose of this analysis was to assess potential predictors of intra-cranial bleeding (ICB) and gastrointestinal bleeding (GIB) in patients with symptomatic peripheral artery disease (PAD) in UK primary care. Patients with symptomatic PAD diagnosed from 2000 to 2010 were identified from The Health Improvement Network (THIN; N  = 28,484). A nested case-control analysis, adjusted for potential confounders, was performed to calculate odds ratios (ORs) and 95% confidence intervals (CIs) for potential predictors of ICB or GIB...

BACKGROUND: Although there have been several reports regarding the significance of staging lymphadenectomy for early stage ovarian clear cell carcinoma (CCC) patients, there have been few reports focusing on the number of removed lymph nodes. The aim of this study was to evaluate the impact of the number of removed lymph nodes on recurrence-free survival (RFS) in stage I ovarian CCC. METHODS: The subjects were patients with ovarian CCC who underwent surgery between January 1988 and December 2013...

Although severe infections caused by hypervirulent Klebsiella pneumoniae isolates, such as K1 isolates belonging to sequence type (ST) 23, have been a significant problem in Asian countries, epidemiology of these isolates in Japan remains unclear. We performed a nationwide molecular epidemiological study of K. pneumoniae K1 and K2 isolates in Japan. Of the 259K. pneumoniae isolates collected, 14 and 16 isolates were identified as capsular genotypes K1 and K2, respectively. All K1 isolates were ST23 or its closely related clones and showed high genetic similarity by pulsed-field gel electrophoresis (PFGE) and the DiversiLab system (DL)...

BACKGROUND: Ureaplasma species (Usp) are the most prevalent genital Mycoplasma isolated from the urogenital tract of both men and women. Usp may be commensals in the genital tract but may also be contributors to a number of pathological conditions of the genital tract. Because they can also just colonize the genital tract of healthy people, their pathogenic role can be difficult to prove. OBJECTIVES: The aim of the study was to evaluate the efficacy of a quantitative polymerase chain reaction (qPCR) method for the discrimination between infection and colonization by measuring prevalence of Usp in asymptomatic versus symptomatic patients...

Circumcision is the oldest surgical operation known to mankind. It probably originated as a less radical form of genital mutilation inflicted on prisoners of war. Over time it was adopted by the Egyptian priesthood and nobility, perhaps inspired by the mythology of Osiris. In turn, circumcision became part of the Jewish and Muslim religious cultures. In contrast, ancient Greeks valued an intact prepuce, as evident from the nude figures of Renaissance art. In the 19th century, circumcision was touted as a treatment for excessive masturbation, seizures, epilepsy, and paraplegia...

Tra1 is an essential component of the SAGA/SLIK and NuA4 complexes in S. cerevisiae , recruiting these co-activator complexes to specific promoters. As a PIKK family member, Tra1 is characterized by a C-terminal phosphoinositide 3-kinase (PI3K) domain. Unlike other PIKK family members (e.g. Tor1, Tor2, Mec1, Tel1), Tra1 has no demonstrable kinase activity. We identified three conserved arginine residues in Tra1 that reside proximal or within the cleft between the N- and C-terminal subdomains of the PI3K domain...

PURPOSE: Laparoscopic liver resection is widely used for liver tumors, but its utility in patients with cirrhosis remains controversial. The aim of this study was to assess the surgical outcomes of laparoscopic liver resection in patients with liver cirrhosis with specific reference to a difficulty scoring system. METHODS: From January 2010 to March 2016, the outcomes of laparoscopic liver resection in 95 patients were retrospectively reviewed. Surgical outcomes were analyzed to identify differences between the liver cirrhosis and non-liver cirrhosis groups; these groups were further stratified to high and low difficulty scores...
