To serve and to protect: the role of decidual innate immune cells on human pregnancy

To serve and to protect: the role of decidual innate immune cells on human pregnancy: AbstractThe maternal–fetal interface undergoes dynamic changes that promote successful development of the embryo/fetal allograft during pregnancy. This immune privilege of the conceptus is mediated through local and systemic cellular responses. In species in which endometrial decidualization accompanies pregnancy, unique immune cell niches are found. Many studies have addressed the enigmatic roles of uterine (u)NK cells as killers and helpers because they are frequently found in the uterine lining...περισσότερα »
Protease-activated receptors (PARs)—biology and role in cancer invasion and metastasis

Protease-activated receptors (PARs)—biology and role in cancer invasion and metastasis: AbstractAlthough many studies have demonstrated that components of the hemostatic system may be involved in signaling leading to cancer progression, the potential mechanisms by which they contribute to cancer dissemination are not yet precisely understood. Among known coagulant factors, tissue factor (TF) and thrombin play a pivotal role in cancer invasion. They may be generated in the tumor microenvironment independently of blood coagulation and can induce cell signaling through activation of ... περισσότερα »

Applied anatomy of the anterior cranial fossa: what can fracture patterns tell us?: The skull base is uniquely placed to absorb anteriorly directed forces imparted either via the midfacial skeleton or cranial vault. A variety of skull base fracture classifications exist. Less well understood, however, is fracture extension beyond the anterior cranial fossa (ACF) into the middle and posterior cranial fossae. The cases of 81 patients from two UK major trauma centres were studied to examine the distribution of fractures across the skull base and any relationship between the vector of f... περισσότερα »

The impact of schistosomes and schistosomiasis on murine blood coagulation and fibrinolysis as determined by thromboelastography (TEG): AbstractSchistosomes are parasitic platyhelminths that currently infect over 200 million people and cause the chronic debilitating disease schistosomiasis. While these large intravascular parasites can disturb blood flow, surprisingly they do not appear to provoke thrombus formation around them in vivo. In order to determine if the worms can alter their local environment to impede coagulation, we incubated adult worms (50 pairs) in murine blood (50... περισσότερα »

Impact of restless leg syndrome on mortality in patients on hemodialysis: still debatable: The results presented by Stefanidis et al were unexpected [1], since the authors found no association between Restless Leg Syndrome (RLS) and increased mortality among patients on hemodialysis.

However, RLS in patients with end-stage renal disease, including those on hemodialysis, may have additional non-traditional risk factors, especially mineral and bone disorders(MBD).

Time window for recanalization in basilar artery occlusion: Speculative synthesis: Basilar artery occlusion (BAO) is one of the most devastating forms of stroke and few patients have good outcomes without recanalization.

Human papillomavirus 16 (HPV16) is the most prevalent HR-HPV. HPV oncogenesis is driven by two viral oncoproteins, E6 and E7, which are expressed through alternative splicing of a polycistronic RNA to yield four major splice isoforms (E6 full length, E6*I, E6*II, E6*X).

Pan Canadian Rash Trial: A Randomized Phase III Trial Evaluating the Impact of a Prophylactic Skin Treatment Regimen on Epidermal Growth Factor Receptor-Tyrosine Kinase Inhibitor-Induced Skin Toxicities in Patients With Metastatic Lung Cancer [Treatment-Related Complications]: Purpose Erlotinib is an epidermal growth factor receptor inhibitor approved for patients with advanced non–small-cell lung cancer (NSCLC) whose epidermal growth factor receptor expression status is positive or unknown. Although it is efficacious, erlotinib can cause skin toxicity. This prospective, randomized ...περισσότερα »

Radiation Dose-Response Relationship for Risk of Coronary Heart Disease in Survivors of Hodgkin Lymphoma [Treatment-Related Complications]: Purpose Cardiovascular diseases are increasingly recognized as late effects of Hodgkin lymphoma (HL) treatment. The purpose of this study was to identify the risk factors for coronary heart disease (CHD) and to quantify the effects of radiation dose to the heart, chemotherapy, and other cardiovascular risk factors. Patients and Methods We conducted a nested case-control study in a cohort of 2,617 5-year HL survivors, treated between 1965 and 19...περισσότερα »

Direct application of bFGF without edge trimming on human subacute tympanic membrane perforation To investigate the feasibility of direct application of basic fibroblast growth factor (bFGF) without edge trimming on human subacute traumatic tympanic membrane perforation (TMP). Spontaneous resolution of a petrous apex cholesterol granuloma Cholesterol granuloma is the most common primary lesion of the petrous apex. Management of petrous apex cholesterol granuloma has evolved in recent years from primary surgical treatment to conservative observation. In this article, a case of spontane...περισσότερα »

Upfront Genotyping of DPYD*2A to Individualize Fluoropyrimidine Therapy: A Safety and Cost Analysis [Clinical Trials]: Purpose Fluoropyrimidines are frequently prescribed anticancer drugs. A polymorphism in the fluoropyrimidine metabolizing enzyme dihydropyrimidine dehydrogenase (DPD; ie, *DPYD***2A*) is strongly associated with fluoropyrimidine-induced severe and life-threatening toxicity. This study determined the feasibility, safety, and cost of *DPYD***2A* genotype–guided dosing. Patients and Methods Patients intended to be treated with fluoropyrimidine-based chemotherapy were...περισσότερα »

Arthropod venom Hyaluronidases: biochemical properties and potential applications in medicine and biotechnology: AbstractHyaluronidases are enzymes that mainly degrade hyaluronan, the major glycosaminoglycan of the interstitial matrix. They are involved in several pathological and physiological activities including fertilization, wound healing, embryogenesis, angiogenesis, diffusion of toxins and drugs, metastasis, pneumonia, sepsis, bacteremia, meningitis, inflammation and allergy, among others. Hyaluronidases are widely distributed in nature and the enzymes from mammalian spermato... περισσότερα »
Tumor necrosis factor-alpha (TNF-α) contributes in inflammation and has been implicated in the development of colorectal cancer (CRC)

Polymorphisms of tumor necrosis factor alpha in Middle Eastern population with colorectal cancer: AbstractTumor necrosis factor-alpha (TNF-α) contributes in inflammation and has been implicated in the development of colorectal cancer (CRC). Single nucleotide polymorphisms (SNPs) in *TNF*-*α* promoter could affect the risk of CRC by regulating TNF-α production. This is the first study to investigate *TNF*-*α* SNPs in a Middle Eastern population. In this study, we examined three SNPs in *TNF*-*α* for association with CRC. One hundred CRC patients and 100 controls were genotyped for *... περισσότερα »
Clindamycin Use in Head and Neck Free Tissue Transfer
Alexandros G. SfakianakisστοOtoRhinoLaryngology - Alexandros G. SfakianakisΠριν από 1 ώρα
Increased Surgical Site Infection Rates following Clindamycin Use in Head and Neck Free Tissue Transfer: Objective The development of surgical site infections (SSIs) can put the viability of free tissue transfer reconstructions at risk, often resulting in considerable postoperative morbidity and prolonged hospitalization. Current antibiotic prophylactic guidelines suggest a first- or second-generation cephalosporin with metronidazole for clean-contaminated cases and recommend clindamycin as an alternative choice in penicillin-allergic patients. This study was designed to examine the... περισσότερα »
Evaluation of a novel Surgicric® cricothyroidotomy device for emergency tracheal access

Evaluation of a novel Surgicric® cricothyroidotomy device for emergency tracheal access in a porcine model: Summary A can't intubate, can't ventilate scenario can result in morbidity and death. Although a rare occurrence (1:50 000 general anaesthetics), it is crucial that anaesthetists maintain the skills necessary to perform cricothyroidotomy, and are well-equipped with appropriate tools. We undertook a bench study comparing a new device, Surgicric®, with two established techniques; the Melker Emergency Cricothyroidotomy, and a surgical technique. Twenty-five anaesthetists perform...περισσότερα »
