In traditional dual-ion systems, the cathode usually is employed as anion-storage materials. Herein, we propose a new dual-ion hybrid supercapacitor with reverse anion/cation-storage mechanism, consisting of a mesoporous (MPs) VN anode as a pivotal anion-storage material and K2-xMn8O16 nanosheet arrays grown on carbon cloth (NSs/CC) as (K-storage) cathode. During charge/discharge, the anode and cathode reversibly store/release OH- ions and K+ ions, respectively. Herein, the MPs VN as anion-storage electrode can operate in an alkaline condition and deliver a high capacitance of 251 mF cm-2 with desired low-voltage plateau. More importantly, benefiting from unique reverse dual-ion mechanism, the (MPs VN-K2-xMn8O16 NSs/CC) hybrid device displays excellent rate performance and satisfying area capacitance along with good durability of 92.2% after 10,000 cycles at a scan rate of 100 mV s-1. It offers new ideas to expand the range of anion-storage materials in dual-ion hybrid supercapacitors.Compared with conventional von Neumann's architecture-based processors, neuromorphic systems provide energy-saving in-memory computing. We present here a 3D neuromorphic humanoid hand designed for providing an artificial unconscious response based on training. The neuromorphic humanoid hand system mimics the reflex arc for a quick response by managing complex spatiotemporal information. A 3D structural humanoid hand is first integrated with 3D-printed pressure sensors and a portable neuromorphic device that was fabricated by the multi-axis robot 3D printing technology. The 3D neuromorphic robot hand provides bioinspired signal perception, including detection, signal transmission, and signal processing, together with the biomimetic reflex arc function, allowing it to hold an unknown object with an automatically increased gripping force without a conventional controlling processor. The proposed system offers a new approach for realizing an unconscious response with an artificially intelligent robot.Understanding size-dependent properties of 2D materials is crucial for their optimized performance when incorporated through solution routes. In this work, the chemical nature of MoS2 as a function of nanosheet size is investigated through the spontaneous reduction of chloroauric acid. Microscopy studies suggest higher gold nanoparticle decoration density in smaller nanosheet sizes, resulting from higher extent of reduction. Further corroboration through surface-enhanced Raman scattering using the gold-decorated MoS2 nanosheets as substrates exhibited an enhancement factor of 1.55 × 106 for smaller nanosheets which is 7-fold higher as compared to larger nanosheets. These plasmonic-semiconductor hybrids are utilized for photodetection, where decoration is found to impact the photoresponse of smaller nanosheets the most, and is optimized to achieve responsivity of 367.5 mAW-1 and response times of ∼17 ms. The simplistic modification via solution routes and its impact on optoelectronic properties provides an enabling platform for 2D materials-based applications.Background To protect developing brain from any unfavorable effects, it is necessary to construct experimental techniques that can sensitively detect and evaluate developmental toxicity. We have previously shown that brain perivascular tissues, especially perivascular macrophages (PVMs), respond sensitively even to weak stimuli by foreign toxicants such as low-dose exposure to nanoparticle. This paper shows the protocol of a novel staining method that enables easy detection and rapid evaluation of brain perivascular abnormalities. Methods As weak stimulus, low-dose of carbon black nanoparticle (95 μg/kg) or titanium dioxide nanoparticle (100 μg/kg) was intranasally administered to pregnant mice at gestational days 5 and 9. The offspring brains were used to confirm the properties of PVMs and to find suitable protocols for the detection and evaluation of the mild denaturation of PVMs. Furthermore, various procedures of novel combinational double staining including periodic acid-Schiff (PAS) staining and immunohsues, such as mild denaturation of PVMs, were sensitively and easily determined by the PAS-immunohistochemical double-staining method. This double staining method is a powerful tool to assess brain perivascular injuries including PVM denaturation and the relationship between the expression of various molecules and the morphology of PVMs. We propose that the observation of the tissue around brain blood vessels using the double staining provides potential endpoints to evaluate developmental neurotoxicity.Paracetamol, or acetaminophen (AAP), is the most commonly used analgesic during pregnancy and early life. While therapeutic doses of AAP are considered harmless during these periods, recent findings in both humans and rodents suggest a link between developmental exposure to AAP and behavioral consequences later in life. The aim of this study is to evaluate the impact of neonatal exposure to clinically relevant doses of AAP on adult spontaneous behavior, habituation, memory, learning, and cognitive flexibility later in life using a mouse model. Markers of oxidative stress, axon outgrowth, and glutamatergic transmission were also investigated in the hippocampus during the first 24 h after exposure. In addition, potential long-term effects on synaptic density in the hippocampus have been investigated. In a home cage setting, mice neonatally exposed to AAP (30 + 30 mg/kg, 4 h apart) on postnatal day 10 displayed altered spontaneous behavior and changed habituation patterns later in life compared to controls. VBIT12 These mice also displayed reduced memory, learning and cognitive flexibility compared to control animals in the Morris water maze. An increase of markers for oxidative stress was observed in the hippocampus 6 h after AAP exposure. As AAP is the first choice treatment for pain and/or fever during pregnancy and early life, these results may be of great importance for risk assessment. Here we show that AAP can have persistent negative effects on brain development and suggest that AAP, despite the relatively low doses, is capable to induce acute oxidative stress in the hippocampus.
A novel deep learning image reconstruction (DLIR) algorithm for CT has recently been clinically approved.

To assess low-contrast detectability and dose reduction potential for CT images reconstructed with the DLIR algorithm and compare with filtered back projection (FBP) and hybrid iterative reconstruction (IR).

A customized upper-abdomen phantom containing four cylindrical liver inserts with low-contrast lesions was scanned at CT dose indexes of 5, 10, 15, 20 and 25mGy. Images were reconstructed with FBP, 50% hybrid IR (IR50), and DLIR of low strength (DLL), medium strength (DLM) and high strength (DLH). Detectability was assessed by 20 independent readers using a two-alternative forced choice approach. Dose reduction potential was estimated separately for each strength of DLIR using a fitted model, with the detectability performance of FBP and IR50 as reference.

For the investigated dose levels of 5 and 10mGy, DLM improved detectability compared to FBP by 5.8 and 6.9percentage points (p.p.), and DLH improved detectability by 9.6 and 12.3 p.p., respectively (all p<.007). With IR50 as reference, DLH improved detectability by 5.2 and 9.8 p.p. for the 5 and 10mGy dose level, respectively (p<.03). With respect to this low-contrast detectability task, average dose reduction potential relative to FBP was estimated to 39% for DLM and 55% for DLH. Relative to IR50, average dose reduction potential was estimated to 21% for DLM and 42% for DLH.

Low-contrast detectability performance is improved when applying a DLIR algorithm, with potential for radiation dose reduction.

Computed tomography scan indicated that dacryocystoceles were bilateral and asymmetrical, with large dimensions at the right side and associated to a right side maxillary sinus mucocele. The right dacryocystocele was surgically removed, and the histology indicated characteristics of the lacrimal sac. The liquid content of the dacryocystocele was negative for microbes. The atypical mucocele in the maxillary sinus disappeared after dacryocystocele removal probably, due to recovery of sinus drainage.
To study circumferential trabeculotomy for congenital glaucoma using Glaucolight illuminated microcatheter.

This was a prospective, uncontrolled, consecutive interventional study of 25 eyes of 25 patients with primary congenital glaucoma (PCG) underwent circumferential trabeculotomy done with an illuminated microcatheter through a period of 18-24 months in ophthalmology department, faculty of medicine, Minia University, Egypt. Patients' data of 12 months' follow-up were recorded. The primary target was the mean intraocular pressure (IOP) study in which complete success was defined as an IOP ≤21 mm Hg and at least a 30% reduction without the use of antiglaucoma drugs and a qualified success when medications were used to reach this aim. The secondary target was studying the corneal diameter and cup disc ratio change.

The mean IOP (mm Hg) was reduced from 27.28 ± 3.46 preoperatively to 17.50 ± 5.09 at the final postoperative visit (
 < 0.001). The mean follow-up period length was (18 months). A qualified success rate was reached to 88%, complete success in 76% and failure in 12%. No serious surgical complications were observed.

Circumferential trabeculotomy accomplished by an illuminated microcatheter achieved a significant IOP lowering with either qualified or complete success in most of eyes with no significant ocular complications and it can be the first option in pediatric PCG surgery.

To report the 12 months outcomes of treatment naïve polypoidal choroidal vasculopathy (PCV) in patients with ≥20/40 Snellen's best-corrected visual acuity (BCVA).

This was a retrospective study including eyes treated with monotherapy of anti-vascular endothelial growth factors (VEGF) agents (bevacizumab, ranibizumab, aflibercept, and ziv-aflibercept) on a pro-re-nata (PRN) protocol. Photodynamic therapy using verteporfin (vPDT) was used as rescue therapy. The primary study objective was change in BCVA at 12 months. Secondary objectives included change in optical coherence tomography parameters central macular thickness (CMT) and pigment epithelial detachment (PED) height, the mean number of injections, and treatment-free interval at 12 months.

A total of 18 eyes of 18 patients (7 males, 11 females) were included. The mean age was 58.0 ± 12.0 years. BCVA at baseline and 12 months were 0.16 ± 0.08 (Snellen equivalent 20/30) and 0.15 ± 0.15 logarithm of the minimum angle of resolution (20/30), respectively.
