uticle collagens and cuticlins are molecular targets for plant cysteine proteinases. However, the presence of tyrosine cross-links in nematode cuticle proteins seriously impeded protein identification by proteomic analyses. Multiple cuticle targets exist, probably making resistance to this new anthelmintic slow to develop.

Ivermectin is widely used in human and animal medicine to treat and prevent parasite nematode infections. It has been suggested that its mode of action requires the host immune system, as it is difficult to reproduce its clinical efficacy in vitro. We therefore studied the effects of a single dose of ivermectin (Stromectol

-0.15mg/kg) on cytokine levels and immune cell gene expression in human volunteers. This dose reduces bloodstream microfilariae rapidly and for several months when given in mass drug administration programmes.

Healthy volunteers with no travel history to endemic regions were given 3-4 tablets, depending on their weight, of either ivermectin or a placebo. Blood samples were drawn immediately prior to administration, 4h and 24h afterwards, and complete blood counts performed. Serum levels of 41 cytokines and chemokines were measured using Luminex

and expression levels of 770 myeloid-cell-related genes determined using the NanoString nCounter

Overall, our data do not support a direct effect of ivermectin, when given at the dose used in current filarial elimination programmes, on the human immune system.

Navigating health systems in host countries can be a challenge for refugees, particularly in a multi-provider system such as Lebanon. Syrian refugees in Lebanon face a high burden of Non-Communicable Diseases (NCDs) including diabetes mellitus. Evidence on how refugees navigate the health system is essential to improve provision of NCD services. We conducted a qualitative study amongst Syrian diabetes patients visiting Médecins Sans Frontières (MSF) clinics in one urban and one rural setting in Lebanon to explore factors influencing choice of and pathways to diabetes care.

In-depth interviews were conducted with male and female adult participants with DM type 1 or type 2 who were receiving treatment at MSF clinics. Participants were recruited using convenience sampling. Interviews were conducted in Arabic and directly transcribed and translated into English. Data were coded in NVivo and analyzed using an inductive thematic approach.

A total of 29 in-depth interviews were conducted with 13 men and 16 women. Knowledge and understanding of diabetes management differed among participants. Syrian refugees in Lebanon gathered information about health services for diabetes largely from social networks of family and peers rather than through formal means. Pathways to care included different combinations of providers such as clinics, pharmacists and informal providers.

Syrian refugees with diabetes in Lebanon face considerable challenges in navigating the health care system due to their vulnerable status and limited knowledge of the host country systems. To ensure access to care for diabetes, efforts need to be made to support patients' orientation in the Lebanese health system.

Toxoplasma gondii infections are common in humans and animals worldwide. Among all intermediate hosts of T. gondii, captive marsupials from Australia and New Zealand are highly susceptible to clinical toxoplasmosis. However, most free-range marsupials establish chronic T. gondii infection. Infected marsupial meat may serve as a source of T. gondii infection for humans. Differences in mortality patterns in different species of kangaroos and other marsupials are not fully understood. Lifestyle, habitat, and the genotype of T. gondii are predicted to be risk factors. For example, koalas are rarely exposed to T. gondii because they live on treetops whereas wallabies on land are frequently exposed to infection.

The present review summarizes worldwide information on the prevalence of clinical and subclinical infections, epidemiology, and genetic diversity of T. gondii infecting Australasian marsupials in their native habitat and among exported animals over the past decade. The role of genetic types of T. gondiilated or genotyped from most macropods in the USA and other countries. Thus, clinical toxoplasmosis in marsupials imported from Australia is most likely to occur from infections acquired after importation.

Most Australasian marsupials in their native land, Australia and New Zealand, have high prevalence of T. gondii, and kangaroo meat can be a source of infection for humans if consumed uncooked/undercooked. The genotypes prevalent in kangaroos in Australia and New Zealand were genetically distinct from those isolated or genotyped from most macropods in the USA and other countries. Thus, clinical toxoplasmosis in marsupials imported from Australia is most likely to occur from infections acquired after importation.

Early challenges to axonal physiology, active transport, and ultrastructure are endemic to age-related neurodegenerative disorders, including those affecting the optic nerve. Chief among these, glaucoma causes irreversible vision loss through sensitivity to intraocular pressure (IOP) that challenges retinal ganglion cell (RGC) axons, which comprise the optic nerve. Early RGC axonopathy includes distal to proximal progression that implicates a slow form of Wallerian degeneration. In multiple disease models, including inducible glaucoma, expression of the slow Wallerian degeneration (Wld

) allele slows axon degeneration and confers protection to cell bodies.

Using an inducible model of glaucoma along with whole-cell patch clamp electrophysiology and morphological analysis, we tested if Wld

also protects RGC light responses and dendrites and, if so, whether this protection depends upon RGC type. We induced glaucoma in young and aged mice to determine if neuroprotection by Wld

on anterograde axonal transport and spatial contrast acuity depends on age.

We found Wld

protects dendritic morphology and light-evoked responses of RGCs that signal light onset (αON-Sustained) during IOP elevation. However, IOP elevation significantly reduces dendritic complexity and light responses of RGCs that respond to light offset (αOFF-Sustained) regardless of Wld

. As expected, Wld

preserves anterograde axon transport and spatial acuity in young adult mice, but its protection is significantly limited in aged mice.

The efficacy of Wld

in conferring protection to neurons and their axons varies by cell type and diminishes with age.

Mechanical chest compression devices are accepted alternatives for cardiopulmonary resuscitation (CPR) under specific circumstances. Current devices lack prospective and comparative data on their specific cardiovascular effects and potential for severe thoracic injuries.

To compare CPR effectiveness and thoracic injuries of two mechanical chest compression devices in pigs.

Prospective randomised trial.

Eighteen male German landrace pigs.

Ventricular fibrillation was induced in anaesthetised and instrumented pigs and the animals were randomised into two intervention groups. Mechanical CPR was initiated by means of LUCAS™ 2 (mCCD1) or Corpuls™ cpr (mCCD2) device. Advanced life support was applied for a maximum of 10 cycles and animals achieving ROSC were monitored for 8 h. Ventilation/perfusion measurements were performed and blood gas analyses were taken. Thoracic injuries were assessed via a standardised damage score.

Five animals of the mCCD1 group and one animal of the mCCD2 group achieved ROSC (p = 0.048). Only the mCCD1 animals survived until the end of the monitoring period (p < 0.01). MCCD1 animals showed less pulmonary shunt (p = 0.025) and higher normal V/Q (p = 0.017) during CPR. MCCD2 animals showed significantly more severe thoracic injuries (p = 0.046).

The LUCAS 2 device shows superior resuscitation outcomes and less thoracic injuries compared to Corpuls cpr when used for experimental CPR in juvenile pigs. Researchers should be aware that different mCCDs for experimental studies may significantly influence the respective outcome of resuscitation studies and affect comparability of different trials. Controlled human and animal CPR studies and a standardised post-resuscitation injury evaluation could help to confirm potential hazards.

Trial approval number G16-1-042-E4.Immunotherapy has ushered in an exciting new era for cancer treatment. The recent discovery and success of immune checkpoint blockade and chimeric antigen receptor (CAR) T cell adoptive cell transfer has raised interest in using other immune cells, including Natural Killer (NK) cells, which might overcome some limitations with CAR T cell therapy. In this review article, we discuss the evidence that cellular metabolism is crucial for NK cell effector function. Acalabrutinib BTK inhibitor Additionally, potential strategies to optimise the metabolism of therapeutic NK cells for improved function within the metabolically adverse tumour microenvironment will be explored.

Doxorubicin (DOX), a widely used chemotherapeutic agent, can cause neurodegeneration in the brain, which leads to a condition known as chemobrain. In fact, chemobrain is a deteriorating condition which adversely affects the lives of cancer survivors. This study aimed to examine the potential therapeutic effects of bone marrow mesenchymal stem cells (BMSCs) and their derived exosomes (BMSCs-Exo) in DOX-induced chemobrain in rat models.

Chemobrain was induced by exposing rats to DOX (2 mg/kg, i.p) once weekly for 4 consecutive weeks. After 48 h of the last DOX dose, a subset of rats was supplied with either an intravenous injection of BMSCs (1 × 10

) or a single dose of 150 μg of BMSCs-Exo. Behavioral tests were conducted 7 days post injection. Rats were sacrificed after 14 days from BMSCs or BMSCs-Exo injection.

BMSCs and BMSCs-Exo successfully restored DOX-induced cognitive and behavioral distortion. These actions were mediated via decreasing hippocampal neurodegeneration and neural demyelination throupoptotic, and oxidative stress state. Proposed mechanisms of the protective effects of bone marrow stem cells (BMSCs) and their exosomes (BMSCs-Exo) in doxorubicin (DOX)-induced chemobrain. Blue arrows induce. Red arrows inhibit.

BMSCs and their derived exosomes offer neuroprotection against DOX-induced chemobrain via genetic and epigenetic abrogation of hippocampal neurodegeneration through modulating Wnt/β-catenin and hedgehog signaling pathways and through reducing inflammatory, apoptotic, and oxidative stress state.
