Monocyte phagocytosis of malaria β-haematin in the presence of artemisinin, amodiaquine, chloroquine, doxycycline, primaquine, pyrimethamine and quinine.

The intraerythrocytic malaria parasite digests haemoglobin to provide amino acids for metabolism and releases toxic haem that is sequestered into haemozoin, a non-toxic, insoluble, crystalline pigment. Following erythrocyte rupture, haemozoin is released into circulation and phagocytosed by monocytes. Phagocytosed haemozoin and antimalarial drugs have both been reported to modulate monocyte functions. This study determined the effects of therapeutic concentrations of seven antimalarial drugs; amodiaquine, a...


The Timing of Chemoprophylaxis in Autologous Microsurgical Breast Reconstruction.

Patients undergoing autologous breast reconstruction are at high risk of perioperative venous thromboembolic events. The efficacy of chemoprophylaxis in decreasing venous thromboembolic events is well established, but the timing of chemoprophylaxis remains controversial. The authors compare the incidence of bleeding following preoperative versus postoperative initiation of chemoprophylaxis in microvascular breast reconstruction.

Practice patterns of VTE chemoprophylaxis after discharge following hepatic and pancreatic resections for cancer: A survey of hepatopancreatobiliary surgeons.

Patients with hepatopancreatobiliary (HPB) malignancies undergoing resection are prone to venous thromboembolism (VTE), and current guidelines recommend up to 28 days of chemoprophylaxis after major surgery. We sought to determine the practice patterns among HPB surgeons for use of chemoprophylaxis after discharge. A survey on VTE chemoprophylaxis after oncologic HPB operations was distributed to attending surgeons at the 18 HPB fellowship training programs in the United States and Canada. Of the HPB surge...


Revisiting the Cardiotoxic Effect of Chloroquine.

Cardiotoxicity is a well-known side effect of chloroquine. Several studies have proposed chloroquine as a potential anti-diabetic treatment but do not address this problem. The current study investigated the effect of ex vivo chloroquine treatment on (1) heart function and glucose uptake, (2) mitochondrial function and (3) in vivo treatment on heart function.

Development and Evaluation of a Novel HNB Based Isothermal Amplification Assay for Fast Detection of Pyrimethamine Resistance (S108N) in .

Sulphadoxine and pyrimethamine (SP) have been used as long-acting partner antimalarial drugs in artemisinin combination therapy (ACT) for falciparum malaria. The emergence and increasing spread of SP resistance in malaria-endemic areas have become a challenge for the control of malaria. Therefore, regular monitoring of the mutation status of partner drugs is important for the better management of drug policy. There are limitations with traditional molecular methods and there is an urgent need for an easy me...

Combination CpG + MPL adjuvant in RSV F protein single dose priming of infant and adult age mice wa...

Accepters, fence sitters, or rejecters: Moral profiles of vaccination attitudes.

Childhood vaccination is a safe and effective way of reducing infectious diseases. Yet, public confidence in vaccination is waning, driven in part by the 'manufacture of doubt' by anti-vaccination activists and websites. However, there is little research examining the psychological underpinnings of anti-vaccination rhetoric among parents.

Ascorbic acid prevents chloroquine-induced toxicity in inner glial cells.

Vaccination of hamsters with Opisthorchis viverrini extracellular vesicles and vesicle-derived recombinant tetraspanins induces antibodies that block vesicle uptake by cholangiocytes and reduce parasite burden after challenge infection.

The liver fluke Opisthorchis viverrini infects several million people in Southeast Asia. Adult flukes live in the bile ducts of humans, where they cause hepatobiliary pathology, including cholangiocarcinoma. Here, we investigated the potential of extracellular vesicles (EVs) secreted by the fluke and defined recombinant proteins derived from EVs to generate protective immunity in a hamster vaccination-challenge model.

Chirobiotic V Versus Chiralpak ID for the Enantioselective Chromatographic Separation of Chloroquine: Stability and Validation Study.

Chloroquine is a chiral antimalarial drug and demonstrates enantioselective pharmacodynamic and pharmacokinetic properties. However, this drug is administered as racemate. The knowledge of stereoselective aspects of these agents may be useful to better understand their mechanisms of action and to optimize their safety and/or clinical efficacy. In this study, an enantioselective analytical method for the quantification of chloroquine enantiomers was developed using HPLC-UV. The chromatographic conditions wer...

Information on the costs of providing vaccination is limited, especially for adults.

Vaccination in Germany - Recommendations of STIKO.

The epidemiological effect of vaccination is that it primarily reduces the incidence and prevalence of infectious agents and diseases, providing ideal conditions (also from an economic point of view) for prevention. Goal of vaccination is first the individual protection. Other goals may be "herd immunity", regional repression and global extinction. The STIKO provides recommendations for the implementation of vaccinations and for the implementation of other measures for the specific prevention of communicabl...

Characteristics of regulatory T-cell populations before and after Ty21a typhoid vaccination in children and adults.

Typhoid fever, caused by the pathogen Salmonella enterica serovar Typhi (S. Typhi), is a serious global health concern. Challenge studies with wild type S. Typhi identified associations between gut-homing regulatory T cells (Treg) and development of typhoid disease. Whether oral live-attenuated Ty21a vaccination induces gut-homing Treg remains unclear. Here, we analyze pediatric and adult Treg pre- and post-Ty21a vaccination in an autologous S. Typhi-antigen presentation model to address this knowledge gap....
