To address this, we initially report a bioinformatics analysis toward the identification and categorization of nonredundant SHs in Drosophila melanogaster. Following up on this in silico analysis, leveraging discovery chemoproteomics, we identify and globally map the full complement of SH activities during various developmental stages and in different adult tissues of Drosophila. Finally, as a proof of concept of the utility of this activity atlas, we highlight sexual dimorphism in SH activities across different tissues in adult D. melanogaster, and we propose new research directions, resources, and tools that this study can provide to the fly community.Bacterial/fungal biofilm-mediated persistent endodontic infections (PEIs) are one of the most frequent clinical lesions in the oral cavity, resulting in apical periodontitis and tooth damage caused by loss of minerals. The conventional root canal disinfectants are poorly bio-safe and harmful to teeth and tissues, making them ineffective in treating PEIs. The development of nanomaterials is emerging as a promising strategy to eradicate disease-related bacteria/fungi. Herein, glucose oxidase (GOx)-modified magnetic nanoparticles (MNPs) were synthesized via a facile and versatile route for investigating their effects on removing PEI-related bacterial/fungal biofilms. It is found that GOx was successfully immobilized on the MNPs by detecting the changes in the diameter, chemical functional group, charge, and magnetic response. Further, we demonstrate that GOx-modified MNPs (GMNPs) exhibit highly effective antibacterial activity against Enterococcus faecalis and Candida albicans. Moreover, the antibacterial/fungal activity of GMNPs is greatly dependent on their concentrations. Importantly, when placed in contact with bacterial/fungal biofilms, the dense biofilm matrix is destructed due to the movement of GMNPs induced by the magnetic field, the formation of reactive oxygen species, and nutrient starvation induced by GOx. Also, the in vitro experiment shows that the as-prepared GMNPs have excellent cytocompatibility and blood compatibility. Thus, GMNPs offer a novel strategy to treat bacteria/fungi-associated PEIs for potential clinical applications.Two-dimensional transition metal dichalcogenides (TMDs) offer numerous advantages over silicon-based application in terms of atomically thin geometry, excellent opto-electrical properties, layer-number dependence, band gap variability, and lack of dangling bonds. The production of high-quality and large-scale TMD films is required with consideration of practical technology. However, the performance of scalable devices is affected by problems such as contamination and patterning arising from device processing; this is followed by an etching step, which normally damages the TMD film. Herein, we report the direct growth of MoSe2 films on selective pattern areas via a surface-mediated liquid-phase promoter using a solution-based approach. Our growth process utilizes the promoter on the selective pattern area by enhancing wettability, resulting in a highly uniform MoSe2 film. Moreover, our approach can produce other TMD films such as WSe2 films as well as control various pattern shapes, sizes, and large-scale areas, thus improving their applicability in various devices in the future. Our patterned MoSe2 field-effect transistor device exhibits a p-type dominant conduction behavior with a high on/off current ratio of ∼106. Thus, our study provides general guidance for direct selective pattern growth via a solution-based approach and the future design of integrated devices for a large-scale application.Cu2SnxGe1-xS3 (CTGS) particles were synthesized via a solid-state reaction and assessed, for the first time, as both photocatalysts and photocathode materials for hydrogen evolution from water. Variations in the crystal and electronic structure with the Sn/Ge ratio were examined experimentally and theoretically. The incorporation of Ge was found to negatively shift the conduction band minimum, such that the bandgap energy could be tuned over the range 0.77-1.49 eV, and also increased the driving force for the photoexcited electrons involved in hydrogen evolution. The effects of the Sn/Ge ratio and of Cu deficiency on the photoelectrochemical performance of Cu2SnxGe1-xS3 and CuySn0.38Ge0.62S3 (1.86 less then y less then 2.1) based photocathodes were evaluated under simulated sunlight. Both variations in the band-edge position and the presence of a secondary impurity phase affected the performance, such that a particulate Cu1.9Sn0.38Ge0.62S3 photocathode was the highest performing specimen. This cathode gave a half-cell solar-to-hydrogen energy conversion efficiency of 0.56% at 0.18 V vs a reversible hydrogen electrode (RHE) and an incident-photon-to-current conversion efficiency of 18% in response to 550 nm monochromatic light at 0 VRHE. More importantly, these CTGS particles also demonstrated significant photocatalytic activity during hydrogen evolution and were responsive to radiation up to 1500 nm, representing infrared light. The chemical stability, lack of toxicity, and high activity during hydrogen evolution of the present CTGS particles suggest that they may be potential alternatives to visible/infrared light responsive Cu-chalcogenide photocatalysts and photocathode materials such as Cu(In,Ga)(S,Se)2 and Cu2ZnSnS4.This study describes the novel use of diffusible iodine-based contrast-enhanced computed tomography (diceCT) as a digital necropsy aid. DiceCT was used postmortem to evaluate the cause of progressive respiratory disease in a juvenile maleo (Macrocephalon maleo). The technique facilitated soft-tissue contrast and a three-dimensional investigation of sinus and choanal anatomy as a means to identify normal and pathologic morphologies. Results showed right-sided narial occlusion by mucoid debris, along with left-sided choanal stenosis caused by osteomyelitis and reactive bone formation. The high spatial resolution afforded by diceCT enabled targeted histology and quantification of the clinical impact of pathologies, which contributed to an effective 60% loss in nasal airway aperture for this individual. This study demonstrates how adding diceCT to traditional necropsy can proffer additional understanding of an individual's pathology, and the resulting data can enhance research programs in vertebrate anatomy, evolution, and health.An approximately 41-yr-old female Asian elephant (Elephas maximus) experiencing forelimb stiffness and decreased range of motion was diagnosed with bilateral carpal osteoarthritis (OA). Standing sedation combined with local anesthesia was used to deliver ultrasound-guided carpal articular injections of an autologous conditioned serum product, interleukin receptor antagonist protein, combined with hyaluronic acid. Within 2 mo of completing therapy, improved range and speed of motion were evident. Reduced inflammation was suggested by decreased carpal articular prostaglandin E2 levels. Subjectively improved clinical signs lasted approximately 5-6 mo, at which point carpal articular injections were repeated. GDC-0879 ic50 Joint inflammatory markers were useful in gauging response to treatment and may provide guidance in the diagnostic and therapeutic approach to elephant OA. On the basis of the positive response noted, interarticular autologous therapy combined with hyaluronic acid should be considered for carpal OA in elephants.Microsporidia are obligate, intracellular fungi. In reptiles, they are most commonly reported in squamates. We report the first detection of microsporidiosis in inland bearded dragons (Pogona vitticeps) from Australia, and for the first time, mixed infections of microsporidium and adenovirus in asymptomatic inland bearded dragons. In one collection there were five individuals, one of which was lethargic, inappetent, and had lost weight. Two large ovarian granulomas were palpated (42 × 23 mm and 26 × 19 mm) and were surgically removed. This animal died shortly after surgery. Histological evaluation of these granulomas revealed granulomatous inflammation within or adjacent to ovarian tissue, containing numerous aggregates of microorganisms consistent with microsporidia. The organisms were confirmed as Encephalitozoon pogonae by polymerase chain reaction (PCR) and sequencing. Agamid adenovirus-1 was also detected. These two infectious agents were also detected by PCR in all the other bearded dragons in this collection (n = 5), all of which were asymptomatic. A single dragon from a second collection presented for a routine wellness examination after the sudden death of another dragon in the collection. This dragon had similar intracelomic masses to the dragon from the first collection. These were removed surgically, but the dragon died 5 wk later following 3 wk of treatment with 25 mg/kg fenbendazole PO q7 days. Necropsy samples were collected and the microsporidian Encephalitozoon pogonae was detected in oral-cloacal swabs, blood, and multiple tissues by PCR and sequencing. Agamid adenovirus-1 was not detected in this dragon.A primiparous white rhinoceros (Ceratotherium simum) gave birth to a calf overnight after approximately 16 mo of gestation. The calf was found dead in the morning. Necrosuppurative placentitis with bacterial inclusions suggestive of coxiellosis was diagnosed histologically, and Coxiella burnetii was identified in fetal tissues and placenta by polymerase chain reaction and immunohistochemistry. Another primiparous female from the same herd aborted later that year after approximately 15 mo of gestation, and coxiellosis was similarly diagnosed in fetal tissues and on vaginal shedding. Estimates of exposure time, duration of vaginal shedding, and phase I and phase II antibody dynamics were determined retrospectively and prospectively for the two confirmed cases. Biosecurity measures were put in place to prevent guests, staff, and conspecific exposure to the organism. No other confirmed cases have occurred in the collection 3 yr after the initial cases. Coxiellosis outbreaks could represent an emerging threat to conservation efforts and ex situ white rhinoceros breeding programs.This case series describes six confirmed cases of mycotic encephalitis and/or mycotic pneumonia in southern pudu (Pudu puda). One case involved a 10.5-yr-old intact female that presented with an inability to stand, eventually progressing to grand mal seizures. Magnetic resonance imaging showed a lesion within the cerebellar vermis with edema causing cerebellar herniation. The animal was euthanized based on a grave prognosis. Gross and histologic examination revealed primary central nervous system phaeohyphomycosis. Curvularia spicifera was sequenced from the cerebellar tissue. This is the first time this fungus has been reported as a primary central nervous system infection in an artiodactyl species. The remaining five cases occurred in neonates between 17 and 67 days old. Clinical signs varied widely, including facial swelling, weakness, posterior paresis, and sudden death. Antifungal therapy was initiated in three neonatal animals but was unsuccessful in each case. All neonates had active mycotic pneumonia caused by Aspergillus fumigatus or Mucor spp. at time of death; four of these animals also had disseminated disease that caused mycotic encephalitis. This case series indicates that fungal disease should be included in the differential diagnosis list of any pudu presenting for neurologic or respiratory clinical signs.
