    Menurut kitab Undang-undang Hukum Perdata Pasal 1150, gadai adalah hak yang diperoleh seseorang yang mempunyai piutang atas suatu barang bergerak. Barang bergerak tersebut diserahkan kepada orang yang berpiutang oleh seorang yang mempunyai utang atau oleh seorang lain atas nama orang yang mempunyai utang. Dan masyarakat masih menganggap Perusahaan syariah dan konvensional sama. Padahal jika dilihat dari segi operasional dan landasan hukumnya jelas berbeda yang dimana pegadaian syariah berpedoman pada Al-Qur'an surah Al-Baqarah ayat 278 tentang larangan riba. Hal ini menunjukkan bahwa produk Ar-Rahn menjadi pilihan terbaik untuk nasabah dalam mengambil keputusan memilih produk gadai syariah atau ar-Rahn

    Spin Splitting Tunable Optical Bandgap in GdN Thin Films for Spin Filtering

    Full text link
    Rare-earth nitrides, such as gadolinium nitride (GdN), have great potential for spintronic devices due to their unique magnetic and electronic properties. GdN has a large magnetic moment, low coercitivity and strong spin polarization suitable for spin transistors, magnetic memories and spin-based quantum computing devices. Its large spin splitting of the optical bandgap functions as a spin-filter that offers the means for spin-polarized current injection into metals, superconductors, topological insulators, 2D layers and other novel materials. As spintronics devices require thin films, a successful implementation of GdN demands a detailed investigation of the optical and magnetic properties in very thin films. With this objective, we investigate the dependence of the direct and indirect optical bandgaps (Eg) of half-metallic GdN, using the trilayer structure AlN(10 nm)/GdN(t)/AlN(10 nm) for GdN film thickness t in the ranging from 6 nm to 350 nm, in both paramagnetic (PM) and ferromagnetic (FM) phases. Our results show a bandgap of 1.6 eV in the PM state, while in the FM state the bandgap splits for the majority (0.8 eV) and minority (1.2 eV) spin states. As the GdN film becomes thinner the spin split magnitude increases by 60%, going from 0.290 eV to 0.460 eV. Our results point to methods for engineering GdN films for spintronic devices

    <p>Abstract</p> <p>Introduction</p> <p>In literature, many different types of foreign objects have been found to have caused eye injuries. These objects can range from organic to inorganic matter such as glass, wood, pencil, nails and fishhooks. Once the injury is recognized, removal of the foreign body and technique used in the management of the injury is very important to reduce further ocular damage. This case report investigates an injury caused by an object similar to a fishhook that pierced into the eyelid in the opposite direction to normal.</p> <p>Case presentation</p> <p>A 19 year old man presented with a one hour history of the right upper eyelid injury from a wire fence. The loose end of the wire penetrated the full thickness of the eyelid in the direction opposite to the normal. The wire passed from under the eyelid, through the centre of the upper lid, to the external surface. After the application of topical anesthetic drops, the eye could be opened manually, the lid averted, and the wire passed out through the defect. No complications were observed. Post removal, the acuity increased to 6/9 and there was no intraocular penetration. Full recovery was observed as well.</p> <p>Conclusion</p> <p>A severe eyelid penetrating injury can be uncomplicated with a full recovery when there is no intraocular penetration. It is also possible to have an injury pass under the lower margin of the lid and penetrate from inside to out, with no associated corneal injury.</p

    Get PDF
    Background: Inflammatory bowel disease (IBD), particularly ulcerative colitis (UC), exhibits varied clinical presentations and extraintestinal manifestations (EIMs) that impact the overall well-being of affected individuals. This systematic review aims to consolidate recent studies conducted in Saudi Arabia to comprehensively analyze the sociodemographic characteristics and clinical features of UC patients, with a specific focus on bone-related complications. Objective: To systematically review Extraintestinal Manifestations of Ulcerative Colitis in Saudi Arabia Methodology: Using the PRISMA guidelines, a comprehensive A systematic search was conducted to identify relevant studies published between 2014 and 2023 on PubMed in English that investigated UC in Saudi Arabia. resulting in the inclusion of seven studies with a collective participant count of 1580. Sociodemographic characteristics &amp; Clinical characteristics, particularly the prevalence of bone-related complications, were examined across these studies. Results: The sociodemographic analysis of 1580 participants from seven studies highlighted variations in extraintestinal manifestations in IBD. Due to the inflammatory nature of the UC disease, and increased glucocorticoids concentrations, bone-related complications, including osteoporosis and osteopenia, were prevalent in UC patients, with distinct patterns observed in different studies. Arthropathy emerged as one of the most common extraintestinal manifestation. Moreover, renal stones are another issue for these patients. Finally, all of these manifestations contribute to the prevalence of anxiety and depression symptoms that was identified among UC patients, that indicated that fifth of these cohort suffer from, psychological disease. Conclusion: This systematic review provides a comprehensive overview of recent studies on UC in Saudi Arabia, emphasizing the prevalence of bone-related complications as predominant extra intestinal manifestations. The findings underscore the importance of addressing these complications in the management of UC patients, necessitating regular testing of the bone density in these patients and provide supplements and other necessary treatments for these patients. Moreover, it is important to consider the psychological impact of such disease on the quality of life of patients. Comprehensive multi-disciplinary medical teams need to work together to address various clinical aspects regarding Ulcerative colitis. This does not only include gastroenterologist, nephrologists and general internists, but also include psychologists/therapists to ensure all patients needs are addressed. Finally, further research is needed to have comprehensive view of UC in Saudi Populations and improve the overall quality of care

    Aims The aim of this study was to investigate the outcomes of Vancouver type B2 and B3 fractures by performing a systematic review of the methods of surgical treatment which have been reported. Materials and Methods A systematic search was performed in Ovid MEDLINE, Embase and the Cochrane Central Register of Controlled Trials. For inclusion, studies required a minimum of ten patients with a Vancouver type B2 and/or ten patients with a Vancouver type B3 fracture, a minimum mean follow-up of two years and outcomes which were matched to the type of fracture. Studies were also required to report the rate of re-operation as an outcome measure. The protocol was registered in the PROSPERO database. Results A total of 22 studies were included based on the eligibility criteria, including 343 B2 fractures and 167 B3 fractures. The mean follow-up ranged from 32 months to 74 months. Of 343 Vancouver B2 fractures, the treatment in 298 (86.8%) involved revision arthroplasty and 45 (12.6%) were treated with internal fixation alone. A total of 37 patients (12.4%) treated with revision arthroplasty and six (13.3%) treated by internal fixation only underwent further re-operation. Of 167 Vancouver B3 fractures, the treatment in 160 (95.8%) involved revision arthroplasty and eight (4.8%) were treated with internal fixation without revision. A total of 23 patients (14.4%) treated with revision arthroplasty and two (28.6%) treated only with internal fixation required re-operation. Conclusion A significant proportion, particularly of B2 fractures, were treated without revision of the stem. These were associated with a higher rate of re-operation. The treatment of B3 fractures without revision of the stem resulted in a high rate of re-operation. This demonstrates the importance of careful evaluation and accurate characterisation of the fracture at the time of presentation to ensure the correct management. There is a need for improvement in the reporting of data in case series recording the outcome of the surgical treatment of periprosthetic fractures. We have suggested a minimum dataset to improve the quality of data in studies dealing with these fractures

    Despite evidence of a relationship between Apolipoprotein E (APOE) ε4+ and later-life cognitive decline, the lifespan effects of carrying an ε4+ allele on cognitive ageing are not well understood. Evidence of ε4+ advantages in early-life are inconsistent, but not inconsiderable. We explored the proposal that APOE ε4+ cognitive advantages arise only in response to complex and sensitive tasks targeting specific executive functions. We systematically manipulated executive demand within verbal fluency, decision-making, prospective memory, and sustained attention tasks. Participants aged 18–25 years (21 ε4+, 63 ε33) also completed a measure of subjective effort. Under low executive demand, ε4+ made fewer verbal fluency word repeats compared to ε33 carriers. Under high executive demand, ε4+ showed lower costs associated with performing concurrent tasks, greater switching errors, and more verbal fluency root repetition errors. Overall, ε4+ appeared to be showing working memory updating advantages under conditions of low executive demand, more effective resource allocation under elevated levels of executive demand, and errors indicating different strategy use compared to ε33 carriers, including speed-accuracy trade-offs

    <p>Abstract</p> <p>Background</p> <p>Immunohistochemical detection of cold shock proteins is predictive for deleterious outcome in various malignant diseases. We recently described active secretion of a family member, denoted Y-box (YB) protein-1. We tested the clinical and diagnostic value of YB-1 protein fragment p18 (YB-1/p18) detection in blood for malignant diseases.</p> <p>Methods</p> <p>We used a novel monoclonal anti-YB-1 antibody to detect YB-1/p18 by immunoblotting in plasma samples of healthy volunteers (n = 33), patients with non-cancerous, mostly inflammatory diseases (n = 60), hepatocellular carcinoma (HCC; n = 25) and advanced solid tumors (n = 20). YB-1/p18 was then tested in 111 patients with chronic liver diseases, alongside established tumor markers and various diagnostic measures, during evaluation for potential liver transplantation.</p> <p>Results</p> <p>We developed a novel immunoblot to detect the 18 kD fragment of secreted YB-1 in human plasma (YB-1/p18) that contains the cold-shock domains (CSD) 1-3 of the full-length protein. YB-1/p18 was detected in 11/25 HCC and 16/20 advanced carcinomas compared to 0/33 healthy volunteers and 10/60 patients with non-cancerous diseases. In 111 patients with chronic liver disease, YB-1/p18 was detected in 20 samples. Its occurrence was not associated with advanced Child stages of liver cirrhosis or liver function. In this cohort, YB-1/p18 was not a good marker for HCC, but proved most powerful in detecting malignancies other than HCC (60% positive) with a lower rate of false-positive results compared to established tumor markers. Alpha-fetoprotein (AFP) was most sensitive in detecting HCC, but simultaneous assessment of AFP, CA19-9 and YB-1/p18 improved overall identification of HCC patients.</p> <p>Conclusions</p> <p>Plasma YB-1/p18 can identify patients with malignancies, independent of acute inflammation, renal impairment or liver dysfunction. The detection of YB-1/p18 in human plasma may have potential as a tumor marker for screening of high-risk populations, e.g. before organ transplantation, and should therefore be evaluated in larger prospective studies.</p

    Spatial navigation deficits — overlooked cognitive marker for preclinical Alzheimer disease?

    Get PDF
    Detection of incipient Alzheimer disease (AD) pathophysiology is critical to identify preclinical individuals and target potentially disease-modifying therapies towards them. Current neuroimaging and biomarker research is strongly focused in this direction, with the aim of establishing AD fingerprints to identify individuals at high risk of developing this disease. By contrast, cognitive fingerprints for incipient AD are virtually non-existent as diagnostics and outcomes measures are still focused on episodic memory deficits as the gold standard for AD, despite their low sensitivity and specificity for identifying at-risk individuals. This Review highlights a novel feature of cognitive evaluation for incipient AD by focusing on spatial navigation and orientation deficits, which are increasingly shown to be present in at-risk individuals. Importantly, the navigation system in the brain overlaps substantially with the regions affected by AD in both animal models and humans. Notably, spatial navigation has fewer verbal, cultural and educational biases than current cognitive tests and could enable a more uniform, global approach towards cognitive fingerprints of AD and better cognitive treatment outcome measures in future multicentre trials. The current Review appraises the available evidence for spatial navigation and/or orientation deficits in preclinical, prodromal and confirmed AD and identifies research gaps and future research priorities

    Current strategies for treatment of intervertebral disc degeneration: substitution and regeneration possibilities

    Get PDF
    Background: Intervertebral disc degeneration has an annual worldwide socioeconomic impact masked as low back pain of over 70 billion euros. This disease has a high prevalence over the working age class, which raises the socioeconomic impact over the years. Acute physical trauma or prolonged intervertebral disc mistreatment triggers a biochemical negative tendency of catabolic-anabolic balance that progress to a chronic degeneration disease. Current biomedical treatments are not only ineffective in the long-run, but can also cause degeneration to spread to adjacent intervertebral discs. Regenerative strategies are desperately needed in the clinics, such as: minimal invasive nucleus pulposus or annulus fibrosus treatments, total disc replacement, and cartilaginous endplates decalcification. Main Body: Herein, it is reviewed the state-of-the-art of intervertebral disc regeneration strategies from the perspective of cells, scaffolds, or constructs, including both popular and unique tissue engineering approaches. The premises for cell type and origin selection or even absence of cells is being explored. Choice of several raw materials and scaffold fabrication methods are evaluated. Extensive studies have been developed for fully regeneration of the annulus fibrosus and nucleus pulposus, together or separately, with a long set of different rationales already reported. Recent works show promising biomaterials and processing methods applied to intervertebral disc substitutive or regenerative strategies. Facing the abundance of studies presented in the literature aiming intervertebral disc regeneration it is interesting to observe how cartilaginous endplates have been extensively neglected, being this a major source of nutrients and water supply for the whole disc. Conclusion: Severalinnovative avenues for tackling intervertebral disc degeneration are being reported â from acellular to cellular approaches, but the cartilaginous endplates regeneration strategies remain unaddressed. Interestingly, patient-specific approaches show great promise in respecting patient anatomy and thus allow quicker translation to the clinics in the near future.The authors would like to acknowledge the support provided by the Portuguese Foundation for Science and Technology (FCT) through the project EPIDisc (UTAP-EXPL/BBBECT/0050/2014), funded in the Framework of the “International Collaboratory for Emerging Technologies, CoLab”, UT Austin|Portugal Program.

    In the CMS Experiment, muon detection in the forward direction is accomplished by cathode strip chambers~(CSC). These detectors identify muons, provide a fast muon trigger, and give a precise measurement of the muon trajectory. There are 468 six-plane CSCs in the system. The efficiency of finding muon trigger primitives (muon track segments) was studied using~36 CMS CSCs and cosmic ray muons during the Magnet Test and Cosmic Challenge~(MTCC) exercise conducted by the~CMS experiment in~2006. In contrast to earlier studies that used muon beams to illuminate a very small chamber area (< ⁣0.01< \! 0.01~m2^2), results presented in this paper were obtained by many installed CSCs operating {\em in situ} over an area of  ⁣23\approx \! 23~m2^2 as a part of the~CMS experiment. The efficiency of finding 2-dimensional trigger primitives within 6-layer chambers was found to be~99.93±0.03%99.93 \pm 0.03\%. These segments, found by the CSC electronics within 800800~ns after the passing of a muon through the chambers, are the input information for the Level-1 muon trigger and, also, are a necessary condition for chambers to be read out by the Data Acquisition System
