In this work, the diversity of the genus in the Nordic Seas and the North Atlantic waters south of Iceland is studied based on the analyses of molecular markers (mitochondrial COI, 16S rDNA and nuclear ITS2) and morphological characters. Our results showed the presence of at least five genetic lineages in the studied material which could also be morphologically identified by their segmental annulation patterns, the number and the shape of acicular spines, and the length and the shape of pygidial lobes. The species name is assigned to one of the lineages restricting its geographical and vertical distribution to the deep-sea areas north of Iceland and Jan Mayen, and three lineages are described as new species (i.

Introduction: For women who have experienced failed attempts at in vitro fertilization (IVF) and face medical issues, leading to infertility, the renewed effort to seek fertility treatment, coupled with decreasing likelihood of success, can exert substantial emotional and physical strains. Consequently, many couples opt to discontinue treatment before attaining pregnancy. The objective of this study was to evaluate the reproductive outcomes in patients with unsuccessful prior IVF attempts who received a complementary treatment designed to alleviate emotional distress and burden.

Introduction: Studies on mind-body approaches in patients with advanced pancreatic ductal adenocarcinoma (PDAC) are rare. We performed a pilot study with follow-up until 1 year to explore changes in pain, quality of life (QoL), stress, and negative emotions in patients with advanced PDAC, who regularly practiced a standardized form of spiritual meditation in addition to standard medical care.

Methods: At baseline and every 2 months for a maximum of 1 year, global pain, QoL (global, SEIQoL, FACT-G), spiritual well-being (FACIT-Sp), perceived stress (PSQ-20), anxiety and depression (HADS), and diurnal cortisol secretion (cortisol slope) were assessed.

This study examined the effects of meditative states in experienced meditators on present-moment awareness, subjective time, and self-awareness while assessing meditation-induced changes in heart-rate variability and breathing rate. A sample of 22 experienced meditators who practiced meditation techniques stressing awareness of the present moment (average 20 years of practice) filled out subjective scales pertaining to sense of time and the bodily self and accomplished a metronome task as an operationalization of present-moment awareness before and after a 20 min meditation session (experimental condition) and a 20 min reading session (control condition) according to a within-subject design. A mixed pattern of increased sympathetic and parasympathetic activity was found during meditation regarding heart-rate measures.

Early school times clash with the late sleep of adolescents, leading to wide-spread sleep restriction in students. Evidence suggests that delaying school starts is beneficial for sleep and recent studies investigated whether this also translates into improved academic achievement. We thus conducted a systematic review of the literature on school start times, grades and test scores in middle and high-school students.

In Australia, the deep-water (bathyal and abyssal) benthic invertebrate fauna is poorly known in comparison with that of shallow (subtidal and shelf) habitats. Benthic fauna from the deep eastern Australian margin was sampled systematically for the first time during 2017 RV 'Investigator' voyage 'Sampling the Abyss'. Box core, Brenke sledge, and beam trawl samples were collected at one-degree intervals from Tasmania, 42°S, to southern Queensland, 24°S, from 900 to 4800 m depth.

Article Synopsis
  • Migraine is a prevalent condition among children and adolescents, but there hasn't been a comprehensive comparison of various nonpharmacological treatments for it.
  • This study conducted a systematic review and network meta-analysis to assess whether nonpharmacological treatments are more effective than simply being on a waiting list, analyzing data from multiple reputable sources.
  • The results showed that certain interventions like self-administered treatments and psychological methods were significantly more effective than the waiting list, but when evaluating each treatment individually, none showed strong statistical significance, highlighting a need for further research in this area.

Recent research shows that placebo mechanisms can be utilized in ethical and legal ways such as in open-label conditions, when patients know that they receive placebos, and through psychological interventions aiming to optimize patients' expectations. Showing that placebo interventions are also cost-efficient could improve their acceptability. To review studies that performed health economic evaluations (HEEs) of intentional placebo interventions and to review studies that intentionally applied placebo interventions and reported outcomes eligible for HEEs.
