BACKGROUND AND IMPORTANCE: During intramedullary lesion surgery, the lesion site and the posterior median sulcus (PMS) should be accurately identified prior to myelotomy to avoid severe injury of the posterior funiculus. However, intramedullary lesions are fundamentally invisible until the myelotomy is performed. Furthermore, the PMS location is frequently unclear due to lesion-induced swelling or distortion of the spinal cord. Intraoperative indocyanine green videoangiography (ICG-VA) followed by FLOW 800 analysis, which shows vascularization of the spinal parenchyma, may provide a solution for these problems in specific cases...

Scholars have posited that childhood socialisation experiences may play a key role in influencing behaviours and attitudes that contribute to the acquisition of HIV. This study examined the links between past ethnic-racial and gender socialisation, sexual assertiveness and the safe sexual practices of African American college women utilising a cluster analytic approach. After identifying separate racial-gender and ethnic-gender socialisation profiles, results indicated that ethnic-gender socialisation cluster profiles were directly associated with sexual assertiveness and safer sex behaviour...

Pablo Jiménez-Bonilla, Yi Wang
Butanol is a precursor of many industrial chemicals, and a fuel that is more energetic, safer and easier to handle than ethanol. Fermentative biobutanol can be produced using renewable carbon sources such as agro-industrial residues and lignocellulosic biomass. Solventogenic clostridia are known as the most preeminent biobutanol producers. However, until now, solvent production through the fermentative routes is still not economically competitive compared to the petrochemical approaches, because the butanol is toxic to their own producer bacteria, and thus, the production capability is limited by the butanol tolerance of producing cells...

Over the last decade several novel surgical treatment options and devices for glaucoma have been developed. All these developments aim to cause as little trauma as possible to the eye, to safely, effectively, and sustainably reduce intraocular pressure (IOP), to produce reproducible results, and to be easy to adopt. The term "micro-invasive glaucoma surgery (MIGS)" was used for summarizing all these procedures. Currently MIGS is gaining more and more interest and popularity. The possible reduction of the number of glaucoma medications, the ab interno approach without damaging the conjunctival tissue, and the probably safer procedures compared to incisional surgical methods may explain the increased interest in MIGS...

OBJECTIVE: College students are a group at risk for contracting sexually transmitted infections (STIs). While they are generally well informed about STIs, they do not consistently use condoms. An important element in preventing STIs is safer sex communication, especially with a sexual partner. This may be difficult, however, because of a lack of experience in talking about safer sex or because of the absence of suitable role models. In this study, a narrative intervention was tested that was developed to provide receivers with a social script for safer sex communication...

Antisense oligonucleotide (ASO) gapmers downregulate gene expression by inducing enzyme-dependent degradation of targeted RNA and represent a promising therapeutic platform for addressing previously undruggable genes. Unfortunately, their therapeutic application, particularly that of the more potent chemistries (e.g., locked-nucleic-acid-containing gapmers), has been hampered by their frequent hepatoxicity, which could be driven by hybridization-mediated interactions. An early de-risking of this liability is a crucial component of developing safe, ASO-based drugs...

Transportation agencies need efficient methods to determine how to reduce bicycle accidents while promoting cycling activities and prioritizing safety improvement investments. Many studies have used standalone methods, such as level of traffic stress (LTS) and bicycle level of service (BLOS), to better understand bicycle mode share and network connectivity for a region. However, in most cases, other studies rely on crash severity models to explain what variables contribute to the severity of bicycle related crashes...

OBJECTIVE: To examine whether gene expression analysis of a large-scale Parkinson disease (PD) patient cohort produces a robust blood-based PD gene signature compared to previous studies that have used relatively small cohorts (≤220 samples). METHODS: Whole-blood gene expression profiles were collected from a total of 523 individuals. After preprocessing, the data contained 486 gene profiles (n = 205 PD, n = 233 controls, n = 48 other neurodegenerative diseases) that were partitioned into training, validation, and independent test cohorts to identify and validate a gene signature...

Brucellosis is a globally distributed zoonotic disease that causes animal and human diseases. Although effective, the current Brucella vaccines (strain M5-90 or others) have several drawbacks. The first is their residual virulence for animals and humans and the second is their inability to differentiate natural infection from that caused by vaccination. In the present study, Brucella melitensis M5-90 manB mutant (M5-90ΔmanB) was generated to overcome these drawbacks. M5-90ΔmanB showed significantly reduced survival in macrophages and mice, and induced strong protective immunity in BALB/c mice...

Regional plexus and nerve blocks are a common technique in modern anesthesia. Since ultrasound machines are available in many departments, the role of nerve stimulation is highly discussed and different approaches to perform the blocks are taken into account. Common technique for electrical nerve stimulation is searching for a stimulating threshold of 0.4-0.5mA using an impulse width of 0.1ms. We present our hypothesis of using all possible information with a new concept of protective nerve stimulation together with first data supporting our theory...

These guidelines are a consensus document developed by a working party of the Australian and New Zealand Anaesthetic Allergy Group (ANZAAG) to provide an approach to the investigation of perioperative anaphylaxis. They focus primarily on the use of skin testing as it is the investigation with the greatest clinical utility for the identification of the likely causative agent and potentially safer alternatives. The practicalities and process of skin testing, its limitations, and the place of other tests are discussed...

Many N-methyl-d-aspartate (NMDA) receptor antagonists have been used to treat neurodegenerative diseases induced by glutamate excitotoxicity in clinics. However, the universality of the glutamic acid neurotransmitter system makes the glutamic acid receptor blockers inefficient and unsafe. Thus, regulating the downstream signaling pathway in the excitotoxicity of glutamic acid may be a more effective and safer way to antagonize the glutamic acid receptor. In this study, we investigated the effect of deferoxamine (DFO), an iron chelator, on the NMDA-induced excitotoxicity...

Previous research suggests darkness increases the risk of a collision involving a pedestrian and the severity of any injury suffered. Pedestrian crossings are intended to make it safer to cross the road, but it is not clear whether they are effective at doing this after-dark, compared with during daylight. Biannual clock changes resulting from transitions to and from daylight saving time were used to compare RTCs in the UK during daylight and darkness but at the same time of day, thus controlling for potential influences on RTC numbers not related to the ambient light condition...

Beer is one of the most frequently consumed fermented beverages in the world, and it has been part of the human diet for thousands of years. Scientific evidence obtained from the development of new techniques of food analysis over the last two decades suggests that polyphenol intake derived from moderate beer consumption may play a positive role in different health outcomes including osteoporosis and cardiovascular risk and the relief of vasomotor symptoms, which are commonly experienced during menopause and are an important reason why women seek medical care during this period; here, we review the current knowledge regarding moderate beer consumption and its possible effects on menopausal symptoms...

More than 30 drugs for antiretroviral therapy (ART), including integrase inhibitors (INIs), have been approved by the U.S. Food and Drug Administration (FDA) as of 2017. Integrase is the third essential enzyme in the cycle of human immunodeficiency virus (HIV) replication. INIs can effectively inhibit the replication of HIV and HIV is less prone to develop resistance to INIs clinically. Previous studies based on 7 phase III clinic trials indicate that INIs have satisfactory efficacy and tolerability in patients infected with HIV...

BACKGROUND: Attending school may have a strong preventative association with sexually transmitted infections among young women, but the mechanism for this relationship is unknown. One hypothesis is that students who attend school practice safer sex with fewer partners, establishing safer sexual networks that make them less exposed to infection. SETTING: We used longitudinal data from a randomized controlled trial of young women age 13-20 in the Bushbuckridge district, South Africa, to determine if the percentage of school days attended, school dropout and grade repetition are associated with having a partner five or more years older (age-disparate) and with the number of sexual partners in the previous 12 months...

The human ether-à-go-go channel (hEag1 or KV10.1) is a cancer-relevant voltage-gated potassium channel that is overexpressed in a majority of human tumors. Peptides that are able to selectively inhibit this channel can be lead compounds in the search for new anticancer drugs. Here, we report the activity-guided purification and electrophysiological characterization of a novel KV10.1 inhibitor from the sea anemone Anthopleura elegantissima. Purified sea anemone fractions were screened for inhibitory activity on KV10...
