Reducing the abundances of invasive species by removals aims to minimize their ecological impacts and enable ecosystem recovery. Removal methods are usually selective, modifying phenotypic traits in the managed populations. However, there is little empirical evidence of how removal-driven changes in multiple phenotypic traits of surviving individuals of invasive species can affect ecosystem functioning and recovery. Overcoming this knowledge gap is highly relevant because individuals are the elemental units of ecological processes and so integrating individual-level responses into the management of biological invasions could improve their efficiency. Here we provide novel demonstration that removals by trapping, angling and biocontrol from lakes of the globally invasive crayfish Procambarus clarkii induced substantial changes in multiple phenotypic traits. A mesocosm experiment then revealed that these changes in phenotypic traits constrain recovery of basic ecosystem functions (decomposition of organic matter, benthic primary production) by acting in the opposite direction than the effects of reduced invader abundance. selleck inhibitor However, only minor ecological impacts of invader abundance and phenotypic traits variation remained a year after its complete eradication. Our study provides quantitative evidence to an original idea that removal-driven trait changes can dampen recovery of invaded ecosystems even when the abundance of invasive species is substantially reduced. We suggest that the phenotypic responses of invaders to the removal programme have strong effects on ecosystem recovery and should be considered within the management of biological invasions, particularly when complete eradication is not achievable.Bariatric surgery is associated with near-immediate remission of type 2 diabetes and recently suggested as a treatment for type 2 diabetes. Specifically, Roux-en-Y gastric bypass has been a focus of much research, but still, the mechanisms of action are only partly elucidated. We aim to investigate whether some mechanisms might be mediated by free fatty acids (FFAs). We measured eight fractionated FFAs before and up to 2 years after Roux-en-Y gastric bypass surgery in 207 patients, divided into three groups. One non-diabetic group, one diabetic group with post-operative remission and one diabetic group with persistent diabetes after surgery. Pre- and postoperative levels of fractionated FFAs were compared within and between groups. The sum of the measured FFAs were lower in the group with persistent diabetes, compared to the other groups. The pre-surgery level of linoleic acid in the group with persistent diabetes was significantly lower compared to the other two groups. The levels of fractionated FFAs decreased from pre-surgery to three months after surgery, except for oleic acid and arachidonic acid and for Docosahexaenoic acid (DHA) in the non-diabetic group. The FFAs with decreasing levels from pre-surgery to three months post-surgery are all precursors to oleic acid, arachidonic acid, and DHA, respectively, which may imply a drift, indicating that they need to be sustained at an acceptable level for optimal metabolic function. The fact that the sum of the measured FFAs is lower in the group with persistent diabetes may suggest that this group and the group with diabetes remission represent two distinct types of type 2 diabetes. It is proposed that linoleic acid could be used as a biomarker to determine the plausibility for type 2 diabetes remission after Roux-en-Y gastric bypass surgery.
To investigate the causes and risk of death in a large cohort of Korean patients with rheumatoid arthritis (RA).

Patients in the Hanyang BAE (Bae registry of Autoimmune diseases for Epidemiology) RA cohort who fulfilled the American College of Rheumatology criteria were analyzed. A total of 2355 patients were enrolled from October 2001 to December 2015. Mortality data were derived by linking with data from the Korean National Statistical Office. Standardized mortality ratio was estimated by dividing observed deaths by expected number of deaths in the general population.

Over the observation period, 225 deaths were reported. Total age- and sex-adjusted standardized mortality ratio was 1.65 (95% confidence interval 1.44-1.87). The most common cause of death was malignancy (40 cases; 17.8%), followed by respiratory disease (38 cases; 16.9%) and cardiovascular disease (32 cases; 14.2%). Mortality rate and causes of death differed according to year and age of RA onset. Compared with survivors, individuals who died were more likely to be male, smokers, diagnosed with RA at an older age, and to have long disease duration, higher erythrocyte sedimentation rate and C-reactive protein, higher rheumatoid factor positivity rate, more severe radiographic damage, and more comorbidities.

The mortality rate of patients with RA remains higher than that of the general population. Therefore, to improve the survival of patients with RA, attention should be paid to the management of comorbidities as well as to the RA itself.

It causes multiple severe complications such as intestinal obstruction, chronic abdominal pain, and female infertility. To prevent PPA, several antiadhesion materials and drug delivery systems composed of biomaterials are used clinically, and clinical antiadhesive is one of the important applications nowadays. In addition to several commercially available materials, like film, spray, injectable hydrogel, powder, or solution type have been energetically studied based on natural and synthetic biomaterials such as alginate, hyaluronan, cellulose, starch, chondroitin sulfate, polyethylene glycol, polylactic acid, etc. Moreover, many kinds of animal adhesion models, such as cecum abrasion models and unitary horn models, are developed to evaluate new materials' efficacy. A new animal adhesion model based on hepatectomy and conventional animal adhesion models is recently developed and a new adhesion barrier by this new model is also developed.
