To describe a patient's condition and clinical progress, admitted to King Abdulaziz University Hospital, Jeddah, Kingdom of Saudi Arabia with Coronaviruses disease-19 (COVID-19) infection who presented initially with gastrointestinal symptoms. The novel COVID-19 disease does not only affect the respiratory tract but also affects other parts of the body. A 23-year old male patient came to the emergency room suffering from acute abdominal pain and vomiting. The patient appeared to have a complicated course of infection with gastrointestinal manifestations and a perforated duodenal ulcer without any respiratory symptoms. Laboratory and radiographic investigations revealed positive results for COVID-19. The chest CT showed a ground-glass appearance. Accordingly, the patient was referred for an emergency laparotomy and was treated mainly for a perforated duodenal ulcer. Unfortunately, the patient died due to several complications. Patients presenting with gastrointestinal symptoms during this pandemic should be assessed for COVID-19 infection, even if respiratory symptoms are absent.

The design of highly efficient photocatalysts to photoreduce nitrogen (N) to ammonia (NH) under mild conditions is extremely challenging. In this work, various molar ratio of molybdenum (Mo) is incorporated into BiOCl via a hydrothermal process. The resulting Mo-doped BiOCl exhibits remarkable solar-driven activity for N photo fixation without any scavengers or sacrificial agents.

The rise of multidrug-resistant (MDR) bacteria in food products poses a significant threat to public health, necessitating innovative and sustainable antimicrobial solutions. This study investigates the green synthesis of zinc oxide nanoparticles (ZnO-NPs) using extracts to evaluate their antibacterial and antibiofilm activities against MDR strains isolated from sold fish samples. The obtained results show that the contamination with reached 54.

Carbon is nothing less than a rock star in the world of research on allotropes which has a tremendous ability to form several simple and complex allotropic structures of various sp, sp and sp hybridizations, thanks to its flexible chemical structure. By high-pressure experimental and theoretical approaches, new carbon forms were synthesized from known carbon structures. Herein, we report the phase transition from amorphous carbon nanoparticles to a novel thermodynamically stable carbon allotropic structure, denominated as SD carbon (Sivakumar-Dai carbon), obtained through the impact of acoustic shock waves with a transient pressure of 16.

Since photocatalytic and electrocatalytic technologies are crucial for tackling the energy and environmental challenges, significant efforts have been put into exploring advanced catalysts. Among them, perovskite type ABO oxides show great promising catalytic activities because of their flexible physical and chemical properties. In this review, the fundamentals and recent progress in the synthesis of perovskite type ABO oxides are considered.

Self-reported physical activity is associated with lower brain food cue responsiveness in reward-related regions, but relationships utilizing objective physical activity measurement tools have not been explored. This cross-sectional study examined whether device-measured moderate-to-vigorous intensity physical activity and sedentary time are related to neural responses to visual food cues using functional magnetic resonance imaging. Fifty-one healthy adults (30 men, 21 women; mean ± SD: age 26 ± 6 years; body mass index 24.
