Metabolomics based on UHPLC-QToF- and APGC-QToF-MS reveals metabolic pathways reprogramming in response to tidal cycles in the sub-littoral species Mimachlamys varia exposed to aerial emergence.

Mimachlamys varia is a sub-littoral bivalve encountered from Norway to the Mediterranean Sea, which lives mostly byssally attached to rocks. During the low tide period, M. varia individuals, located highest on the shore, may experience short time of aerial exposure and face a low availability of oxygen. Here we report a comparative metabolomic profiling of gill samples of M. varia obtained by both LC-QToF and APGC-QToF mass spectrometry, to analyze metabolic changes occurring during emersion in comparison w...


Assessment of the biological quality of port areas: A case study on the three harbours of La Rochelle: The marina, the fishing harbour and the seaport.

This work was designed to investigate biological impacts at 3 dates (day 0, day 7 and day 21) on black scallops (Mimachlamys varia) in the three ports areas of La Rochelle town in winter 2017. In order to assess the biological effects on the wild population of black scallops, bivalves were place in four different locations: in the three ports (semi-closed areas), and in a marshland uncontaminated site (closed area). Biomarkers of effects (heavy metals) and exposure (oxidative stress and immunological effect...

Does Timing of Surgery Affect Treatment of the Terrible Triad of the Elbow?

BACKGROUND This study investigated the influence of surgical timing on the treatment of terrible triad of the elbow (TTE). MATERIAL AND METHODS After exclusion, 63 patients were enrolled in this study: 20 patients were classified into the emergency group (group A, within 24 h after injury), 26 into the early surgery group (group B, from 4 to 14 days after injury), and 17 into the delayed surgery group (group C, more than 14 days after injury). All patients underwent the same approach, and elbow motion and c...


Isolation and exploitation of minority: Game theoretical analysis.

We investigate various group-size distributions occurring in a situation where each group's resource is exposed to appropriation by other groups. The amount of appropriation depends on the size difference between groups. Our work focuses on the cases where the entire community isolates a small group or even an individual to maximize its gain. While people's basic motivation to form a group can be understood based on the group-size effect on multiplying a collective asset, sensitive factors that induce a asy...

Proximate, fatty acids and metals in edible marine bivalves from Italian market: Beneficial and risk for consumers health.

Seafood is recognized as a healthy food choice due to high contents of essential nutrients, including polyunsaturated fatty acids (PUFAs) of the n-3 family. However, seafood is often contaminated by toxic compounds, which have adverse effects on human health. The aim of this study was to provide information about the percentage of edible part, condition index and the benefit and risk for human consumers health associated to the consumption of eight bivalve species (Flexopecten glaber, Mimachlamys varia, Mod...

Group I introns are widespread in archaea.

Group I catalytic introns have been found in bacterial, viral, organellar, and some eukaryotic genomes, but not in archaea. All known archaeal introns are bulge-helix-bulge (BHB) introns, with the exception of a few group II introns. It has been proposed that BHB introns arose from extinct group I intron ancestors, much like eukaryotic spliceosomal introns are thought to have descended from group II introns. However, group I introns have little sequence conservation, making them difficult to detect with sta...

The role of group cohesion in a group-based behavioral weight loss intervention.

Behavioral weight loss interventions are often delivered in groups. Group cohesion may enhance program attendance and, thereby, weight loss. In this secondary analysis, our goals were to: (1a) assess whether group cohesion measured early in a behavioral weight loss intervention predicts program attendance and weight loss outcomes and, if so, (1b) explore whether attendance mediates the link between group cohesion and weight loss; (2) characterize the association between change in group cohesion and weight l...

Experimental animal study of docetaxel combined with carboplatin in the treatment of retinoblastoma.

The synergistic effects of docetaxel (DTX) combined with carboplatin in the treatment of retinoblastoma (RB) was explored in mouse RB xenografts compared with carboplatin alone and DTX alone groups. Retinoblastoma Y-79 cells (4.0×10/ml) were injected into the vitreous body of the right eye of mice to establish the mouse model of RB xenografts. Then the mice were randomly divided into 4 groups (n=30): DTX combined with carboplatin group (group A), carboplatin group (group B), DTX group (group C) and blank c...

Reply to readers (Manuscript ID: HEP-18-1297).

In our preliminary experiment, we divided patients into 3 groups, 10 patients in each group. Group A received standard medicine treatment (SMT) only. Group B was treated with allogeneic bone marrow-derived MSCs (BM-MSCs) every week for 4 weeks, at a dosage of 1x10 per Kg. For Group C the dosage of BM-MSCs was 10x10 per Kg. No significant difference was found in the levels of liver functions and 24 week survival rate between Group B and Group C (data not published). This may be related with the peripheral ve...

Hypergravity enhances the therapeutic effect of dexamethasone in allergic asthma and rhinitis animal model.

We investigated whether the therapeutic effects of dexamethasone for allergic asthma and rhinitis were enhanced in mice when exposed to hypergravity. Forty mice were divided into 5 groups (n = 8/group): Control group received saline intraperitoneally (i.p.) and intranasally (i.n.); Asthma group received i.p./i.n. ovalbumin (OVA) for inducing allergic asthma/rhinitis; Dexa group received i.n. dexamethasone (0.75 mg/kg) 30 minutes before each OVA challenge; Hypergravity group was subjected to allergic asthma/...

The effects of neoadjuvant chemotherapy on the minimum alveolar concentration (MAC) values of sevoflurane and desflurane in patients with hepatocellular carcinoma (HCC) complicated with jaundice were investigated. Eighty patients with HCC complicated with jaundice were selected. Forty patients underwent the neoadjuvant chemotherapy and were grouped into the desflurane group (Group D) and the sevoflurane group (Group S). Patients in all chemotherapy groups received 2 cycles of chemotherapy prior to surgery a...

Comparison of Congenital Malformations among Babies Born after Administration of Letrozole or Clomiphene Citrate for Infertility Treatment in a Korean Cohort.

This retrospective study investigated and compared the incidence of congenital foetal anomalies after letrozole versus clomiphene citrate (CC) administration for infertility treatment. Data from 142 newborns were included: letrozole group, n = 83; CC group, n = 61. Congenital anomalies were found in 7.2% (6/83) patients in the letrozole group and 18.0% (11/61) patients in the CC group, with no significant between-group difference (p = .066). Major congenital anomaly rate was 2.4% (2/83) in the l...

What is the relationship between the bioaccumulation of chemical contaminants in the variegated scallop Mimachlamys varia and its health status? A study carried out on the French Atlantic coast using the Path ComDim model.

Increasing activity along the French Atlantic coast has led to chronic pollution with, in particular, mixtures of contaminants such as hydrocarbons, phytosanitary products, PCBs and heavy metals. Based on previous research, pollution biomarkers were used in this study as they can indicate health status when monitoring the impact of pollutants on coastal species such as the marine bivalve Mimachlamys varia. Mollusc bivalves were sampled in March 2016, in open and semi-open areas (a harbour zone), from thirte...

Ostracism drives group moralization and extreme group behavior.

Sharing beliefs, particularly moral beliefs, is a way to establish social connections. We hypothesized that ostracism leads people who are high in the need to belong to adhere to the moral beliefs of an ingroup, and that moralizing the beliefs of one's group increases the willingness to endorse extreme behavior on behalf of the group. Across two studies, participants were ostracized or included, rated the moral relevance of their group values, and indicated their endorsement of extreme behavior on behalf of...

The Importance of Structure and Connection for People Living With Schizophrenia: A 33-Year Outpatient Group Experience.

This paper evaluates an outpatient group for persons living with schizophrenia. Qualitative changes and psychiatric admissions among group members were reviewed to measure recovery. Thirty-two members have attended sessions for up to 28 years. Meaningful interactions (e.g., supportive comments) have increased and hospitalizations have decreased. The support of the therapists and the other group members has allowed for personal recovery and developing and maintaining social connections. Prior to starting th...

Stability of anti-A blood group titers among blood group B renal transplant candidates.

As deceased donor kidney allocation is based in part on blood type compatibility, group B candidates are disadvantaged due to their disproportionate representation on the wait list compared to the group B donor pool. To mitigate this discrepancy, group B candidates can receive group A or A B donor kidneys if their anti-A titers are below a predetermined cutoff. Currently, eligibility is reverified quarterly to UNet based on individual center protocols, which can vary due to a lack of set guidelines for moni...

Mechanical Augmentation With Absorbable Alginate Sheet Enhances Healing of the Rotator Cuff.

For anatomical restoration of a repaired rotator cuff, mechanical augmentation of the repaired structure is essential. Using histological and biomechanical evaluation in a rat model, the authors sought to determine the efficacy of an absorbable alginate sheet at the supraspinatus tendon-to-bone repair site for healing of the rotator cuff tear. Forty adult (12 weeks old) male Sprague- Dawley wild-type rats were used in this study. The animals were randomly separated into 2 groups: group 1, conventional supra...

Comparison of two groups for the apolipoprotein E polymorphisms by using next generation sequencing: The first group with three consecutive abortions and the second group with at most one abortion in three consecutive pregnancies.

The importance of apolipoprotein E genotypes and allelic polymorphisms in the etiology of recurrent miscarriage is controversial. We plan to investigate this in a two-group study involving more than a thousand participants. In total, 1046 subjects (802 participants in the first group, 244 participants in the second group) were investigated. Women in the first group had a history of ≥3 consecutive spontaneous miscarriage and women in the second group had at most one miscarriage in three consecutive pregnan...

Specifically, the degree to which variability in racial out-group exposure affects children's use of race to make decisions about unfamiliar individuals (Chinese, White, Southeast Asian) was investigated. Participants (N = 212; M  = 60.51 months) chose functions for novel objects after informants demonstrated their use; indicated with which peer group member to socialize; and ...

Hydrogen treatment reduces tendon adhesion and inflammatory response.

A rat model of tendon repair was established to investigate the effects of hydrogen water on tendon adhesion reduction. Thirty-six Sprague Dawley rats were randomly divided into a normal saline (NS) group and a hydrogen water (HS) group according to the processing reagents after a tendon repairing operation. Pre- and postoperative superoxide dismutase (SOD), malondialdehyde (MDA), and glutathione (GSH) in subjects' serum were observed. Skin fibroblasts were grouped into an NS group, H O group, H group, and...

A Prospective, Controlled, Multicenter Study to Evaluate the Clinical Outcome of Implant Treatment in Women with Osteoporosis/Osteopenia: 5-Year Results.

The impact of osteoporosis on implant treatment is still a matter of debate in the scientific community, as it may possibly lead to higher failure rates. As long-term controlled trials are missing, the aim of this study was to verify the long-term outcome of implants placed in patients with systemic osteoporosis. Postmenopausal women in need of implants underwent bone mineral density measurements in hip and spine, using dual X-ray absorptiometry scans. Based on T-scores, they were divided into 2 groups: gro...

Synergistic Effects of Mesenchymal Stem Cell Transplantation and Repetitive Transcranial Magnetic Stimulation on Promoting Autophagy and Synaptic Plasticity in Vascular Dementia.

rTMS and MSCs transplantation both showed therapeutic effects on cognition impairment in vascular dementia model rats. However, whether these two therapies have synergistic effects and the molecular mechanisms remain unclear. In our present study, rats were randomly divided into six groups: control group, sham operation group, VD group, MSC group, rTMS group and MSC+rTMS group. The VD model rats were prepared using a modified 2VO method. rTMS treatment was implemented at a frequency of 5 Hz, the stimulation...
