BACKGROUND: Upper gastrointestinal bleeding (UGIB) is a common and potentially fatal medical emergency. This study aimed to investigate the frequency, causes, outcomes, and efficacy of endoscopy in the treatment of UGIB at King Fahad Central Hospital in Jazan, Saudi Arabia.METHODS: Between January 2017 and December 2023, a retrospective study was performed including all hospitalized patients with

The minimal SO(10) grand unified theory, augmented by higher-dimensional operators, is based on the following Higgs representations: adjoint 45H, spinor 16H, and complex vector 10H. It was recently realized that, as opposed to the conventional wisdom, any intermediate mass scale has to lie close to the grand unification one. This bears profound consequences for the scalar particles mass spectrum a

Background: We studied the association between cardiorenal function and survival, neurological outcome and trends in survival after in-hospital cardiac arrest (IHCA). Methods: We included cases aged ≥ 18 years in the Swedish Cardiopulmonary Resuscitation Registry during 2008 to 2020. The CKD-EPI equation was used to calculate estimated glomerular filtration rate (eGFR). A history of heart failure

Introduction Simulation-based studies indicate that crisis checklist use improves management of patients with critical conditions in the emergency department (ED). An interview-based study suggests that use of an emergency manual (EM) - a collection of crisis checklists - improves management of clinical perioperative crises. There is a need for in-depth prospective studies of EM use during clinica

We have investigated the optical properties of heterostructured InGaN platelets aiming at red emission, intended for use as nano-scaled light-emitting diodes. The focus is on the presence of non-radiative emission in the form of dark line defects. We have performed the study using hyperspectral cathodoluminescence imaging. The platelets were grown on a template consisting of InGaN pyramids, flatte

Water sources near mining regions are often susceptible to contamination from toxic elements. This study employs machine learning (ML) techniques to evaluate drinking water quality and identify pollution sources near a chromite mine in Iran. Human health risks were assessed using both deterministic and probabilistic approaches. Findings revealed that concentrations of calcium (Ca), chromium (Cr),

Tumour-induced osteomalacia is caused by tumorous production of fibroblast growth factor 23 (FGF23) leading to urinary phosphate wasting, hypophosphataemia and decreased vitamin D activation. The resulting osteomalacia presents with muscle weakness and bone pain but progresses to multiple pathological fractures. Patients often remain undiagnosed for years with severe physical, psychological and ec

When Stockholms Enskilda Bank hired two women in 1864, it waspresumably the first bank in the world to do so. The fashion ofhiring women gradually spread, and bank telling became femaledominated.We describe and analyze this process, identifying threeperiods in the feminization of the Swedish commercial banksector. Economic, institutional, technological, and cultural factorswere all instrumental in

In a joint research project – Human Factors in Air Navigation Services, HUFA – between the Swedish Civil Aviation Administration and Lund University the focus is on human and organizational factors and safety in air traffic control. The Swedish Air Navigation Services (ANS) are undergoing major organizational changes in order to adapt to changing demands on efficiency and technical development in

Nässelqvist’s contribution examines different models for understanding the oral delivery of New Testament writings. He finds evidence in favor of the existence in antiquity of both oral performance from memory and public reading directly from a manuscript. These types of oral delivery not only involved different delivery practices, but were also used in dissimilar settings for distinct text genres

The molecular self-diffusion coefficients were accessed, for the first time, in solutions of microcrystalline cellulose, dissolved in 30 wt% and 55 wt% aqueous tetrabutylammonium hydroxide, TBAH (aq), and in mixtures of 40 wt% TBAH (aq) with an organic co-solvent, dimethylsulfoxide (DMSO), through pulsed field gradient stimulated echo NMR measurements. A two-state model was applied to estimate α (

Aims: Mineralocorticoid receptor antagonists (MRAs) improve outcomes in heart failure with reduced ejection fraction (HFrEF) but remain underused and are often discontinued especially in patients with chronic kidney disease (CKD) due to concerns on renal safety. Therefore, in a real-world HFrEF population we investigated the safety of MRA use, in terms of risk of renal events, any mortality and an

Implantation of demineralized bone matrix in rodents elicits a series of cellular events leading to the formation of new bone inside and adjacent to the implant. This process is believed to be initiated by an inductive protein present in bone matrix. It has been suggested that local growth factors may further regulate the process once it has been initiated. This investigation was designed to study

Working conditions and regulations encourage everyone to participate actively in shaping the surrounding environment in order to increase the social durability. End-users’ participation during the construction process will contribute to building better products that fulfil their needs and requirements. Meanwhile the real estate administrators will achieve a long term economic success if all renter

New and improved preparative routes to the previously known PCP ligands cis-1,3-bis(di-isopropylphosphinito)cyclohexane and cis-1,3-bis[(di-tert-butylphosphino)methyl]cyclohexane are reported. They react with 1 equivalent of dichloro(1,5-cyclooctadiene)platinum(II) [(COD)PtCl2] to give the cis coordinated complex cis-[PtCl2{cis-1,3-bis(di-isopropylphosphinito)}cyclohexane] and the Csp3-H activated

Galectins are a family of β-galactose binding lectins associated with functions such as immunological and malignant events. To study the binding affinity of galectins for natural and artificial saccharides and glycoconjugates we have developed an assay using fluorescence polarization. A collection of fluorescein-conjugated saccharides was synthesized and used as probes with galectins-1 and -3 and

The proper use and exchange of the right packaging-related information in a grocery supply chain is critical to achieve an efficient and responsive packaging logistics system. The use of well-defined packaging-related information that is available for all actors in the supply chain also facilitates an integrated and supply chain-orientated packaging development. The objective of this paper is to d

Immature progenitor cells (generated by in vitro propagation) may provide a useful alternative to primary cells (from dissected embryonic tissue) for transplantation if their migratory and proliferative and differentiation properties can be controlled and directed in vivo. In this study E15 murine EGF-responsive progenitor cells were transplanted to the striatum of adult rats. Simultaneously, thes

Four different ways to detect Kraft and soluble pine lignin using either soluble or immobilised Trametes hirsuta laccase have been investigated. In the first, the concentration of lignin was measured using laccase in homogeneous medium with a Clark electrode. In the second, laccase immobilised onto aminated porous glass beads was used in a reactor submerged into the lignin containing solution and

The t(11;20)(p15;q11) is a rare but recurrent translocation that so far has been described in only four acute myeloid leukemias (AMLs), two treatment-related myelodysplastic syndromes (t-MDSs), and one case of polycythemia vera. Recently, the t(11;20) was shown to result in a fusion of the NUP98 and TOP1 genes, with expression of the NUP98/TOP1 chimera encoded by the der(11)t(11;20), but not of th
