BACKGROUND: The insect cuticle protects against environmental stresses such as insecticides, physical injury, dehydration and pathogenic microorganisms. Structural cuticular proteins (CPs) are the primary components, and are of interest for physiology-based pest management methods. Anopheles sinensis CPs are poorly characterised at present, therefore we performed whole genome sequence analysis and re-analysed available transcriptome data to identify potential insecticide resistance-associated CPs...

Probiotics have been proposed for a number of indications ranging from the hypothetical long-term immunomodulatory effects to proven benefits in the management of different clinical conditions.An increasing number of commercial products containing probiotics are available. In those products, irrespective if it is food, food supplement, medical food, or drug, the probiotic microorganisms have to be present in a sufficient number by the end of the shelf-life, to pass through the gastrointestinal tract resisting acid and bile, to colonize the gut, and to retain functional properties required to obtain the suggested beneficial effect...

Acute myeloid leukemia (AML) developing in patients with chronic lymphocytic leukemia (CLL) is very uncommon and usually associated with prior treatment. Acute promyelocytic leukemia (APL) accounts for a very small proportion of treatment-associated AML. So far, there has been only one reported case of APL occurring post radiation for prostate cancer in a patient with CLL. We report herein the first case of APL and CLL presenting concomitantly in an untreated patient. Evaluation of peripheral blood and bone marrow aspirate with immunohistochemistry, flow cytometry, and FISH to confirm two morphologically, molecularly and genetically distinct leukemic populations characteristic of APL and CLL is required...

Cancer cells reprogram their metabolism to optimize their growth and proliferation in the host microenvironment. For this purpose, they enhance the uptake of extracellular nutrients and deal with the metabolic waste products through the overexpression of numerous membrane proteins including amino-acid transporters (LAT1) and acid-base regulating enzymes, such as carbonic anhydrases (CAs). Here we describe the anti-tumoral effects of a new class of CAXII inhibitors, the glycosyl coumarins on T-ALL/LL cells. These effects appeared to be mediated through inhibition of mTOR/Akt pathway and c-myc downregulation...

PURPOSE: Increasing evidence suggests that Mediterranean Diet (MD) is correlated with reduced risk of breast cancer (BC) and cancer mortality, since it modifies patients' serum antioxidant capacity, body composition and biochemical parameters. The aim of the study was to investigate whether a dietary intervention based on MD has a beneficial effect on these factors. METHODS: In this intervention study, seventy female BC survivors were randomly assigned to (1) the intervention group (personalized dietary intervention based on MD) and (2) the control group (received the updated American Cancer Society Guidelines on Nutrition and Physical Activity for Cancer Prevention and ad libitum diet)...

Despite significant advances in the management and treatment of heart disease in children, there continue to be patients who have worse outcomes than might be expected. A number of risk factors that could be responsible have been identified. Evidence based findings will be reviewed including whether young age and/or reduced body weight exacerbate these responses. For example, newborn children undergoing congenital cardiac surgery are known to have worse outcomes than older children. Evidence exists that newborn hearts do not tolerate ischemia as well as adults; developing irreversible injury sooner and exhibiting at risk metabolic profiles...

International guidelines recommend that the management of knee osteoarthritis (OA) combine both nonpharmacological and pharmacological interventions. Intra-articular (IA) therapies are considered part of this multimodal approach and are well-established Food and Drug Administration (FDA) and European Medicines Agency (EMA)-approved treatments. Areas covered. Safety data for knee OA, including IA corticosteroids, hyaluronic acid, platelet-rich plasma and botulinum toxin are critically reviewed, and evidence- and pratice-based measures to improve safety of IA therapies are discussed...

Infectious diseases are a major global health issue. Diagnosis is a critical first step in effectively managing their spread. Paper-based microfluidic diagnostics first emerged in 2007 as a low-cost alternative to conventional laboratory testing, with the goal of improving accessibility to medical diagnostics in developing countries. In this review, we examine the advances in paper-based microfluidic diagnostics for medical diagnosis in the context of global health from 2007 to 2016. The theory of fluid transport in paper is first presented...

Hypotension commonly occurs in parturients undergoing cesarean delivery under spinal anesthesia. This leads to maternal and neonatal adverse outcomes, including maternal nausea and vomiting and fetal acidosis, and might even lead to cardiovascular collapse if not treated. Arterial dilatation and reduction in systemic vascular resistance are the major contributors to spinal-induced hypotension. Therefore, strategies aimed at expanding the intravascular volume with fluid loading or increasing venous return with lower extremities mechanical compression and lateral tilt have had limited effectiveness in the management of spinal-induced hypotension...

Assessments of watershed-based restoration efforts are rare but are essential for the science of stream restoration to advance. We conducted a watershed scale assessment of Abram Creek before and after implementation of a watershed-based plan designed to maximize ecological recovery from acid mine drainage (AMD) impairment. We surveyed water chemistry, physical habitat, benthic macroinvertebrates, and fish community structure in three stream types: AMD-impacted (14 streams), AMD-treated (13 streams), and unimpaired reference (4 streams)...

OBJECTIVE: A workgroup of clinical experts has developed an Appropriate Use Criteria (AUC) for the use of hyaluronic acid (HA) in the treatment of osteoarthritis (OA) of the knee. The increasingly broad and varied use of HA injections, lack of published clinical guidance, and limited coverage for their use has created the imperative to establish appropriateness criteria. METHODS: The experts of this workgroup represent rheumatology, orthopedic surgery, physiatry, sports medicine, and nursing clinicians with substantive knowledge of intra-articular HA therapy...

Pain is a subjective feeling and one of the defense and alerting mechanisms of the body, which is distinguished from the body senses, including touch sensation and perception of heat, cold, pressure, etc. Pain, discomfort, and edema are very common after dental procedures, especially after periodontal surgeries, usually occurring during the first 24 hours after surgery; such pains are classified as medium to severe pains. Generally, medications are used to manage patients' pain and discomfort. One of the most commonly used medications for pain control is Ibuprofen, which is one of the NSAIDs and is a simple derivative of phenylpropionic acid...

Climate change will affect semiarid ecosystems through severe droughts that increase the competition for resources in plant and microbial communities. In these habitats, adaptations to climate change may consist of thinning - that reduces competition for resources through a decrease in tree density and the promotion of plant survival. We deciphered the functional and phylogenetic responses of the microbial community to six years of drought induced by rainfall exclusion and how forest management affects its resistance to drought, in a semiarid forest ecosystem dominated by Pinus halepensis Mill...

BACKGROUND: Recognition of a broad spectrum of disease and development of Clostridium difficile infection (CDI) and recurrent CDI (rCDI) in populations previously considered to be at low risk has renewed attention on differences in the risk profile of patients. In the absence of primary prevention for CDI and limited treatment options, it is important to achieve a deep understanding of the multiple factors that influence the risk of developing CDI and rCDI. METHODS: We conducted a review of systematic reviews and meta-analyses on risk factors for CDI and rCDI published between 1990 and October 2016...

OBJECTIVES: We describe phaeochromocytoma penetrance in multiple endocrine neoplasia type 2 (MEN2) according to RET protooncogene-specific mutations, and report changes in phaeochromocytoma diagnosis and management from 1968 to 2015. DESIGN: This retrospective chart review included 309 MEN2 patients from one specialised ambulatory care centre. Phaeochromocytoma patients were categorised by diagnosis date: early, 1968-1996, n = 40; and recent, 1997-2015, n = 45. RESULTS: Phaeochromocytoma was diagnosed in 85/309 patients with RET mutations in the following exons (phaeos/all carriers, %): exon 11 (56/120, 46·6%); exon 16 (7/17, 41·2%), exon 10 (14/47, 29·8%), and exon 13-15 (2/116, 1·7%)...
