Liver-targeted polymeric prodrugs delivered subcutaneously improve tafenoquine therapeutic window for malaria radical cure.

Approximately 3.3 billion people live with the threat of malaria. Infection can result in liver-localized hypnozoites, which when reactivated cause relapsing malaria.

The role of exercise for pain management in adults living with and beyond cancer: a systematic review and meta-analysis.

Background: Pain is a common side effect of cancer or cancer treatment that negatively impacts biopsychosocial wellbeing and quality of life. Exercise is a potential intervention to manage pain that is safe and has multiple benefits. The objective was to determine the role of exercise in cancer pain management.

Postnatal maternal mental health and postnatal attachment.

Aims: Maternal mental illness has a significant influence on negative maternal and childhood outcomes. Few studies have focused on both maternal depression and anxiety, or explored the interplay of maternal mental illness and the mother-infant bond. We aimed to examine the relationship between early postnatal attachment and mental illness at 4 and 18 months postpartum.

The Natural History of Aerosolized Infection in Cynomolgus Macaques.

Tularemia is a severe, zoonotic infection caused by the Gram-negative bacterium . Inhalation results in a rapid, severe bacterial pneumonia and sepsis, which can be lethal. Because the cynomolgus macaque is the accepted nonhuman primate model for tularemia, we conducted a natural history study of pneumonic tularemia by exposing macaques to target inhaled doses of 50, 500, or 5000 colony forming units (CFU) of subsp.

Small Particle Aerosol Exposure of African Green Monkeys to MERS-CoV as a Model for Highly Pathogenic Coronavirus Infection.

Emerging coronaviruses are a global public health threat because of the potential for person-to-person transmission and high mortality rates. Middle East respiratory syndrome coronavirus (MERS-CoV) emerged in 2012, causing lethal respiratory disease in »35% of cases. Primate models of coronavirus disease are needed to support development of therapeutics, but few models exist that recapitulate severe disease.

Coccidioidomycosis in Nonhuman Primates: Pathologic and Clinical Findings.

Coccidioidomycosis in nonhuman primates has been sporadically reported in the literature. This study describes 22 cases of coccidioidomycosis in nonhuman primates within an endemic region, and 79 cases of coccidioidomycosis from the veterinary literature are also reviewed. The 22 cases included baboons ( n = 10), macaques ( n = 9), and chimpanzees ( n = 3).

Toxicity and pathophysiology of palytoxin congeners after intraperitoneal and aerosol administration in rats.

Preparations of palytoxin (PLTX, derived from Japanese Palythoa tuberculosa) and the congeners 42-OH-PLTX (from Hawaiian P. toxica) and ovatoxin-a (isolated from a Japanese strain of Ostreopsis ovata), as well as a 50:50 mixture of PLTX and 42-OH-PLTX derived from Hawaiian P. tuberculosa were characterized as to their concentration, composition, in-vitro potency and interaction with an anti-PLTX monoclonal antibody (mAb), after which they were evaluated for lethality and tissue histopathology after intraperitoneal (IP) and aerosol administration to rats.

Stoma care products represent a common and previously underreported source of peristomal contact dermatitis.

Background: Peristomal dermatitis is a common complication for the >700 000 patients in the United States with an ostomy. The role of stoma skin care products in peristomal dermatitis is poorly understood.

Objective: To evaluate stoma skin care products as a cause of peristomal dermatitis.

Effects of Fractional Inspired Oxygen on Cerebral Oxygenation in Preterm Infants following Delivery.

Objectives: To explore regional cerebral oxygen saturations (rcSO2) in preterm neonates initially stabilized with 0.3 fractionated inspired oxygen (FiO2) concentrations. We hypothesized that those infants who received >0.

Experimental infection of cynomolgus macaques (Macaca fascicularis) with aerosolized monkeypox virus.

Monkeypox virus (MPXV) infection in humans results in clinical symptoms very similar to ordinary smallpox. Aerosol is a route of secondary transmission for monkeypox, and a primary route of smallpox transmission in humans. Therefore, an animal model for aerosol exposure to MPXV is needed to test medical countermeasures.

Evaluation of the efficacy of modified vaccinia Ankara (MVA)/IMVAMUNE against aerosolized rabbitpox virus in a rabbit model.

Infection of rabbits with aerosolized rabbitpox virus (RPXV) produces a disease similar to monkeypox and smallpox in humans and provides a valuable, informative model system to test medical countermeasures against orthopoxviruses. Due to the eradication of smallpox, the evaluation of the efficacy of new-generation smallpox vaccines depends on relevant well-developed animal studies for vaccine licensure. In this study, we tested the efficacy of IMVAMUNE [modified vaccinia Ankara-Bavarian Nordic (MVA-BN)] for protecting rabbits against aerosolized RPXV.

Smallpox vaccine does not protect macaques with AIDS from a lethal monkeypox virus challenge.

It is unknown whether smallpox vaccination would protect human immunodeficiency virus type 1 (HIV-1)-infected individuals, because helper CD4(+) cells, the targets of HIV-1 infection, are necessary for the induction of both adaptive CD8(+) cell and B cell responses. We have addressed this question in macaques and have demonstrated that, although smallpox vaccination is safe in immunodeficient macaques when it is preceded by immunization with highly attenuated vaccinia strains, the macaques were not protected against lethal monkeypox virus challenge if their CD4(+) cell count was <300 cells/mm(3). The lack of protection appeared to be associated with a defect in vaccinia-specific immunoglobulin (Ig) switching from IgM to IgG.

Vaccination with gp120-depleted HIV-1 plus immunostimulatory CpG oligodeoxynucleotides in incomplete Freund's adjuvant stimulates cellular and humoral immunity in rhesus macaques.

Whole killed human immunodeficiency virus type 1 (HIV-1) immunogens contain the more conserved epitopes of HIV-1 and therefore may provide some utility as potential HIV-1 vaccine candidates. Previous studies have shown that synthetic oligodeoxynucleotides (ODN) containing unmethylated cytosine-guanine (CpG) dinucleotides trigger rapid stimulation of both CD4+ and CD8+ T cells. Here, we investigated whether immunization of rhesus macaques with an inactivated gp120-depleted HIV-1 immunogen, emulsified in incomplete Freund's adjuvant (IFA) together with immunostimulatory CpG-containing ODN (ODN 2006), would elicit HIV-specific cellular and humoral immune responses.

Hydrogen peroxide and corneal endothelium.

Because of recent evidence of low levels of hydrogen peroxide in the aqueous humor, studies were performed to determine levels of corneal endothelial toxicity as well as factors modifying toxicity. Perfusion of cornea endothelial cells for 3 h with varying concentrations of hydrogen peroxide demonstrated a threshold of toxicity at a concentration between 0.3 and 0.

Photodynamic alteration of cornea endothelium. Relation to bicarbonate fluxes and oxygen concentration.

Corneas were mounted in flux chambers and endothelial bicarbonate fluxes were determined following sensitization of endothelial cells with 5 . 10(-6) M rose bengal and exposure to light. Corneas exposed to light demonstrated an increased passive bicarbonate flux compared to corneas not photosensitized.

Chlorhexidine effects on corneal epithelium and endothelium.

Chlorhexidine digluconate, a soft contact lens disinfectant, was perfused over rabbit corneal peithelial and endothelial surfaces under a variety of concentrations and conditions. Without protein in the bathing solutions, the cornea swelled when chlorhexidine concentrations of 20 microgram/mL or greater were perfused over the endothelium. Scanning electron microscopy demonstrated rounded, swollen cells with loss of microvilli.
