Monocytes are short-lived mononuclear phagocytes that circulate in the bloodstream and comprise two main subpopulations that in the mouse are best defined by the Ly6C marker. Intravascular functions of "classical" Ly6C+ monocytes and their interactions with other lymphoid and myeloid leukocytes in the circulation remain poorly understood. Rather, these cells are known to efficiently extravasate into tissues. Indeed, Ly6C+ monocytes and their descendants have emerged as a third, highly plastic and dynamic cellular system that complements the two classical, tissue-resident mononuclear phagocyte compartments, i...

Incidental appendectomy (IA) could potentially increase the risk of morbidity after abdominal procedures; however, such effect is not clearly established. The aim of our study is to test the association of IA with morbidity after abdominal procedures. We identified 743 (0.37%) IA among 199,233 abdominal procedures in the National Surgical Quality Improvement Program database (2005-2009). Cases with and without IA were matched on the index current procedural terminology code. Patient characteristics were compared using chi-squared test for categorical variables and Student t test for continuous variables...

Atopic dermatitis (AD) is a complex, chronic inflammatory skin disorder affecting more than 10% of UK children and is a major cause of occupation-related disability. A subset of patients, particularly those with severe AD, are persistently colonised with Staphylococcus aureus (S. aureus) and exacerbation of disease is commonly associated with this bacterium by virtue of increased inflammation and allergic sensitisation, aggravated by skin barrier defects. Understanding the complex biology of S. aureus is an important factor when developing new drugs to combat infection...

There is emerging evidence that tubulointerstitial fibrosis is the final common pathway of the majority of chronic progressive renal diseases, including diabetic nephropathy (DN). Zinc, an essential dietary element, has been suggested to be important for a number of protein functions during fibrosis in vivo and in vitro. However, the effect of zinc deficiency (ZnD) on renal interstitial fibrosis in DN remains unclear. The present study investigated the effect and the underlying mechanisms of ZnD on renal interstitial fibrosis during DN using an streptozotocin‑induced model of diabetes with immunofluorescence staining and western blot analysis...

Chinese medicines are emerging as an attractive new generation of anticancer drugs. Here, we explored the impact of salvianolic acid B (Sal B), the major water-soluble compounds of Danshen, on apoptosis and autophagy of human hepatocellular carcinoma cells (HCC). We also investigated the related molecular mechanisms. We found that Sal B exhibits potent ability to inhibit HCC cells viability in a concentration-dependent manner, and to induce apoptosis via the mitochondrial apoptosis pathway. Additionally, Sal B could also induce autophagy...

Synthetic cannabinoids (SCs) are the largest group of compounds currently monitored in Europe by the EU Early Warning System on new psychoactive substances. Emerging recreational use of these products has led to multiple cases of adverse health effects and even death. In contrast to marijuana, where Δ9-tetrahydrocannabinol (Δ9THC) is metabolized to only one major active metabolite, it has been reported that several major phase I metabolites of SCs remain biologically active, exerting cannabinoid (CB) receptor affinity, potency and efficacy greater than Δ9THC...

Collagen networks play an important role in coordinating and regulating collective cellular dynamics via a number of signaling pathways. Here, we investigate the transmission of forces generated by contractile cells in 3D collagen-I networks. Specifically, the graph (bond-node) representations of collagen networks with collagen concentrations of 1, 2 and 4 mg ml(-1) are derived from confocal microscopy data and used to model the network microstructure. Cell contraction is modeled by applying correlated displacements at specific nodes of the network, representing the focal adhesion sites...

Antibiotic resistance has emerged as a major threat to global health care. This is largely due to the fact that many pathogens have developed strategies to acquire resistance to antibiotics. Metallo-β-lactamases (MBL) have evolved to inactivate most of the commonly used β-lactam antibiotics. AIM-1 is one of only a few MBLs from the B3 subgroup that is encoded on a mobile genetic element in a major human pathogen. Here, its mechanism of action was characterised with a combination of spectroscopic and kinetic techniques and compared to that of other MBLs...

BACKGROUND: Surgery-related conditions account for the majority of admissions in primary referral hospitals in Sub-Saharan Africa. The role of surgery in the reduction of global disease burden is well recognized, but there is a great qualitative and quantitative disparity in the delivery of surgical and anaesthetic services between countries. This study aims at estimating the nature and volume of surgery delivered in an entire administrative division of Cameroon. METHODS: In this retrospective survey conducted during the year 2013, we used a standard tool to analyse the infrastructure and human resources involved in the delivery of surgical and anaesthetic services in the Fako division in the south-west region of Cameroon...

Chronic hepatitis B is a worldwide disease, with significant burden on health care systems. While universal vaccination programs have led to an overall decrease in incidence of transmission of hepatitis B, unfortunately, there remain large areas in the world where vaccination against hepatitis B is not practiced. In addition, vertical transmission of hepatitis B persists as a major concern. Hepatitis B treatment of the pregnant patient requires a thorough assessment of disease activity and close monitoring for flares, regardless of initiation of antiviral therapy...

One of the major concerns in the practice of allergy is related to the safety of procedures for the diagnosis and treatment of allergic disease. Management (diagnosis and treatment) of hypersensitivity disorders involves often intentional exposure to potentially allergenic substances (during skin testing), deliberate induction in the office of allergic symptoms to offending compounds (provocation tests) or intentional application of potentially dangerous substances (allergy vaccine) to sensitized patients. These situations may be associated with a significant risk of unwanted, excessive or even dangerous reactions, which in many instances cannot be completely avoided...
