Rhipicephalus sanguineus (Latreille) (Ixodida: Ixodidae) is a three-host dog tick found worldwide that is able to complete its' entire lifecycle indoors. Options for the management of R. sanguineus are limited and its' control relies largely on only a few acaricidal active ingredients. Previous studies have confirmed permethrin resistance and fipronil tolerance in R. sanguineus populations, commonly conferred by metabolic detoxification or target site mutations. Herein, five strains of permethrin-resistant and three strains of fipronil-tolerant ticks were evaluated for metabolic resistance using synergists to block metabolic enzymes...

Idiopathic CD4(+) lymphopenia (ICL) predisposes to opportunistic infections (OIs) but can often remain asymptomatic and does not have a strong association with monogenic mutations. Likewise, cryptococcal meningoencephalitis, the most common OI in ICL, is not strongly associated with monogenic mutations. In this study, we describe 2 patients with ICL plus an additional immune defect: one from an E57K genetic mutation in the nuclear factor-κβ essential modulator, and the other with acquired autoantibodies to granulocyte-macrophage colony-stimulating factor...

BACKGROUND: Cross-border malaria transmission is an important problem for national malaria control programmes. The epidemiology of cross-border malaria is further complicated in areas where Plasmodium falciparum and Plasmodium vivax are both endemic. By combining passive case detection data with entomological data, a transmission scenario on the northwestern Thai-Myanmar border where P. falciparum is likely driven by importation was described, whereas P. vivax is also locally transmitted...

The sporadic outbreaks of highly pathogenic H5N1 avian influenza virus have raised public health concerns. Monoclonal antibodies (MAbs) against hemagglutinin (HA) have been increasingly used successfully for therapeutic purposes. Previously, MAb 9F4, generated against clade 1 H5N1 HA, was observed to have cross-clade neutralizing efficacy and inhibited viral entry by preventing the pH-mediated conformational change of HA. Furthermore, mouse-human chimeric MAb 9F4 was found to retain high degrees of neutralizing activity...

An ultrasonic method is employed to synthesize the Sn doped Zn0.95Sn0.05O quantum dots with green light emission. Sn(2+) and Sn(4+) ions are used to create different optical defects inside Zn0.95Sn0.05O quantum dots and the changing trend of oxygen concentration under different ultrasonic irradiation power are investigated. The photoluminescence spectra are employed to characterize the optical defects of Zn0.95Sn0.05O quantum dots. The UV-vis spectra are used to study the band gap of Zn0.95Sn0.05O quantum dots, which is influenced by their sizes...

Near-infrared spectroscopy studies in children with attention deficit hyperactivity disorder (ADHD) have shown excessive prefrontal activity responsible for coping with interference. However, it is possible that the previous results were influenced by verbal, reading, and memory developments. The flanker task is an interference task that does not require a verbal response, reading, or memorization. We examined activity in the superior frontal cortex (SFC) during the flanker task in 12 children with ADHD and 14 children with typical development using near-infrared spectroscopy...

Mutations in WNT1 cause osteogenesis imperfecta (OI) and early-onset osteoporosis, identifying it as a key Wnt ligand in human bone homeostasis. However, how and where WNT1 acts in bone are unclear. To address this mechanism, we generated late-osteoblast-specific and osteocyte-specific WNT1 loss- and gain-of-function mouse models. Deletion of Wnt1 in osteocytes resulted in low bone mass with spontaneous fractures similar to that observed in OI patients. Conversely, Wnt1 overexpression from osteocytes stimulated bone formation by increasing osteoblast number and activity, which was due in part to activation of mTORC1 signaling...

Osteogenesis imperfecta (OI) is an inherited bone disorder that causes fractures due to impaired production of collagen type I. In recent years, denosumab, a human monoclonal antibody against receptor activator of nuclear factor κB ligand (RANKL), has become widely used as an anti-osteoclastic agent for osteoporosis. This study investigated osteoporotic cases of OI to examine effects of denosumab on bone fragility. This was a retrospective, consecutive case series that included 3 female patients aged 42, 40, and 14 years, respectively...

Osteogenesis imperfecta (OI) is the most common inherited form of bone fragility and includes a heterogenous group of genetic disorders which most commonly result from defects associated with type 1 collagen. 85%-90% of cases are inherited in an autosomal dominant manner and are caused by mutations in the COL1A1 and COL1A2 genes, leading to quantitative or qualitative defects in type 1 collagen. In the last decade, defects in several other proteins involved in the normal processing of type 1 collagen have been described...

Osteogenesis imperfecta (OI) is a bone disorder that can lead to skull base deformities such as basilar invagination, which can cause compression of cranial nerves, including the trigeminal nerve. Trigeminal neuralgia in such cases remains a challenge, given distorted anatomy and deformities. We present an alternative option, consisting in cannulation of the foramen ovale and classical percutaneous treatment. Percutaneous balloon microcompression was performed in a 28 year-old woman with OI and severe trigeminal neuralgia using computed tomography (CT) and radiographic-guided cannulation of the Gasserian ganglion without neuronavigation or stereotactic devices...

We describe the sixth species of bent-toed gecko from the Lesser Sunda Islands, Indonesia. This species was first collected on the banks of the Oi Marai River on the low northern slopes of Gunung (Mount) Tambora on Sumbawa Island. The new species is differentiated from Greater Sunda Islands (including Sulawesi) and Lesser Sunda Islands congeners by having the following unique combination of characters: (1) two scales between the second pair of postmentals in contact with the first pair; (2) dorsal surface of antebrachium tuberculate; (3) no tubercles on dorsal surface of brachium; (4) dorsal surfaces of thigh and crus tuberculate; (5) 18 irregularly aligned, longitudinal rows of keeled tubercles at midbody; (6) 26-27 paravertebral tubercles; (7) 40 ventral scales between indistinct ventrolateral folds; (8) 16-17 fourth-toe subdigital scales; (9) a continuous enlarged precloacal and femoral scales present, with the enlarged femoral scales arranged in three rows; (10) males with five to six precloacal pores, with four larger pores situated in a short groove; (11) femoral pores absent in both sexes; (12) lack of transversely enlarged subcaudal scales; and (13) 7-9 irregular, paired black blotches on the body...

Osteogenesis imperfecta (OI) is a disease caused by defects in type I collagen production that results in brittle bones. While the pathology is mainly caused by defects in the osteoblast lineage, there is also elevated bone resorption by osteoclasts resulting in high bone turnover in severe forms of the disease. Osteoclasts originate from hematopoietic myeloid cells, however changes in hematopoiesis have not been previously documented in OI. In this study, we evaluated hematopoietic lineage distribution and osteoclast progenitor cell frequency in bone marrow, spleen and peripheral blood of osteogenesis imperfecta murine (OIM) mice, a model of severe OI...
