Land-use change and intensification threaten bee populations worldwide, imperilling pollination services. Global models are needed to better characterise, project, and mitigate bees' responses to these human impacts. The available data are, however, geographically and taxonomically unrepresentative; most data are from North America and Western Europe, overrepresenting bumblebees and raising concerns that model results may not be generalizable to other regions and taxa.

There is compelling evidence that more diverse ecosystems deliver greater benefits to people, and these ecosystem services have become a key argument for biodiversity conservation. However, it is unclear how much biodiversity is needed to deliver ecosystem services in a cost-effective way. Here we show that, while the contribution of wild bees to crop production is significant, service delivery is restricted to a limited subset of all known bee species.

Article Synopsis
  • * A new database has been created, containing over 1.6 million samples from 78 countries, which includes data on around 28,000 species experiencing various types of human impacts across different ecosystems.
  • * This comprehensive dataset, part of the PREDICTS project, offers a much broader perspective for analyzing biodiversity trends and will be publicly accessible in 2015, enhancing our understanding of ecological changes.

The 'Individueel functioneren medisch specialisten' (Individual Functioning of Medical Specialists, IFMS) programme is a formative evaluation tool.- The aim of the IFMS programme is to consolidate good practices and to ameliorate those less desirable. - It is an integral system that takes the complexity of the medical profession, the physician as an individual and the expectations and demands from the individual's surroundings into account.

The natural human response to illness is to seek to understand what is happening and to look for help from others. In all cultures, one finds healers, who provide explanations and offer care. Their interventions often have a placebo effect through activation of natural healing processes in the patient.

Background: Hyperthermic intraperitoneal chemotherapy (HIPEC) is more and more used in the treatment of patients with peritoneal carcinomatosis (PC) of different primary tumours. However, survival of patients with PC is still poor. The aim of this study was to evaluate the effects of preoperatively administered bevacizumab and temperature of the perfusion in an experimental model of HIPEC.

Unlabelled: Introduction : Hyperthermic intraperitoneal chemotherapy (HIPEC) is becoming a standard therapy in the treatment of peritoneal carcinomatosis (PC). Compared to systemic chemotherapy, HIPEC improves survival in patients with PC. This therapy has high morbidity rates (up to 41%).

Background: Mucinous adenocarcinoma (MAC) of the colorectum has been known and studied for many years. The prognostic significance of this histological subtype remains controversial. The authors reviewed the prognostic significance of mucinous differentiation in colorectal cancer.

Quadrupole-based inductively coupled-mass spectrometry (ICP-MS) with pneumatic nebulization as a means of sample introduction was employed for quantification of platinum in blood and tissue samples of rats with peritoneal carcinomatosis, receiving intraperitoneal treatment with the Pt-containing chemotherapeutic drug oxaliplatin, and in the perfusate solution used for this purpose. The Pt levels were measured for various treatment conditions, i.e.

Spoiled gradient echo pulse (SPGRE) sequences are commonly used in dynamic contrast-enhanced MRI (DCE-MRI) studies to measure the contrast agent concentration in a tissue of interest over time. However, due to improper tuning of the SPGRE parameters, concentration uncertainty can be very high, even at high signal-to-noise ratio in the MR measurement. In this work, an optimization procedure is proposed for selecting the optimal value of the SPGRE-flip angle FA(opt), given the expected concentration range.

Neuropathic pain (NeP) syndromes remain a difficult-to-treat medical entity. Despite a growing number of pharmacological and invasive analgesic therapies the results remain less than optimal because of insufficient analgesic efficacy and/or occurrence of pronounced side effects. Current guidelines propose the use of multimodal and balanced pharmacological therapies, focused on the underlying pathophysiological mechanisms (mechanistic approach).

Objective: To determine the efficacy of lidocaine 5% patches [Versatis, commercialised by Grünenthal GmbH, Aachen, Germany] in patients with PNCCP.

Background: This study focuses on chronic pain states of a neuropathic nature, located at the scar or over a larger area of the skin around the scar. This post-operative/post-traumatic neuropathic chronic cutaneous pain (PNCCP) may be a side-effect of any incision of the skin in the context of a surgical procedure or a traumatic event.

Article Synopsis
  • The study looked at how well doctors agreed on test results for kids with bladder problems during a research project in Europe.
  • They tested 97 kids with one kind of bladder issue and 105 kids with another, checking their test scores before and after treatment.
  • The results showed that doctors didn't agree much on one type of score but were okay with another type, highlighting that it's important to review tests without bias.

Worldwide agriculture is one of the main drivers of biodiversity decline. Effective conservation strategies depend on the type of relationship between biodiversity and land-use intensity, but to date the shape of this relationship is unknown. We linked plant species richness with nitrogen (N) input as an indicator of land-use intensity on 130 grasslands and 141 arable fields in six European countries.

Article Synopsis
  • The study aimed to compare how certain medical conditions in kids, like urge syndrome and dysfunctional voiding, respond to different treatments.
  • 97 kids with urge syndrome and 105 with dysfunctional voiding were given treatments and observed through special tests before and after.
  • The results showed that changes in bladder activity didn't really help predict how well the treatments would work, suggesting that standard treatments are enough for most kids.

The demographic variability and life history differentiation of two closely related shrubs (Atriplex canescens and A. acanthocarpa) were investigated in the Chihuahuan Desert, and the results were interpreted in the context of theories of coexistence in fluctuating environments. Demographic information was recorded during three annual intervals and analyzed employing matrix projection models.

Agri-environment schemes are an increasingly important tool for the maintenance and restoration of farmland biodiversity in Europe but their ecological effects are poorly known. Scheme design is partly based on non-ecological considerations and poses important restrictions on evaluation studies. We describe a robust approach to evaluate agri-environment schemes and use it to evaluate the biodiversity effects of agri-environment schemes in five European countries.

In the past decades, large amounts of contaminated sediments have been dredged and spread out along rivers. The understanding of the fate and the behaviour of contaminants in dredged sediments is essential to deal with the management of contaminated sediments. Heavy metal leaching behaviour in dredged sediments of different ages since disposal, varying from 10 to 70 years, was assessed by pH(stat) leaching test and potentiometric titrations.

The infrahyoid musculocutaneous flap was described by Wang in 1986. The authors utilize this type of flap since 1994 with an importance that increases in the field of head and neck reconstructive surgery. Their experience of 153 reconstructions in oropharynx and oral cavity showed 128 (84%) cases with good cicatrisation and 25 (16%) with complications.

Purpose: We assessed the relationship between general joint hypermobility (GJH) and lower urinary tract symptoms presenting as nonneurogenic bladder sphincter dysfunction in children.

Materials And Methods: Parents of 89 children 5 to 12 years old who were diagnosed with GJH according to the Beighton and Bulbena scales were asked to fill out a questionnaire concerning symptoms of nonneurogenic bladder sphincter dysfunction, namely daytime urinary incontinence, nighttime urinary incontinence, urinary tract infection, constipation and fecal soiling. The control group comprised 116 healthy schoolchildren 5 to 12 years old.
