Low-temperature vacuum evaporation as a novel dehydration process for the long-term preservation of transplantable human corneal tissue.
Cell Tissue Bank

Academic Ophthalmology, Mental Health and Clinical Neurosciences, School of Medicine, University of Nottingham, Nottingham, UK.
Globally there is a shortage of available donor corneas with only 1 cornea available for every 70 needed. A large limitation to corneal transplant surgery is access to quality donor tissue due to inadequate eye donation services and infrastructure in many countries, compounded by the fact that there are few available long-term storage solutions for effectively preserving spare donor corneas collected in countries with a surplus. In this study, we describe a novel technology termed low-temperature vacuum evaporation (LTVE) that can effectively dry-preserve surplus donor corneal tissue, allowing it to be stored for approximately 5 years, shipped at room temperature, and stored on hospital shelves before rehydration prior to ophthalmic surgery.

American University of Beirut Medical Center, Riad El Solh, PO Box: 11-0236, Beirut, 1107 2020, Lebanon.
Background: Lebanon continues to experience dramatic changes in its medical demography following the ongoing economic crisis of 2019, including brain drain of physicians across different specialties. This paper assesses the landscape of physicians in Lebanon in 2024 to highlight gaps and propose solutions.
Methods: A List of registered physicians is obtained from the Lebanese Order of Physicians (LOP) in Beirut and Tripoli.
The Phytochemical Properties of Low-Grade Longan Syrup and Its Potential Use as a Dietary Supplement for Honey Bees.
Insects
November 2024
Meliponini and Apini Research Laboratory, Department of Entomology and Plant Pathology, Faculty of Agriculture, Chiang Mai University, Chiang Mai 50200, Thailand.
Climate change significantly affects honey bee populations and their access to natural food sources, demanding alternative economic feed sources. Longan stands out as the most important fruit crop in Southeast Asia, but with a surplus of low-grade fruit that is not suitable for the market. This study investigates the potential of longan syrup as an alternative carbohydrate source for honey bees by measuring sugar composition, phytochemical profiles, feed, and survival, as well as the resulting gut microbial changes.

Objective: Aim: The purpose of this study is to comprehensively assess the workload of general practitioners using the time study and the WISN method..
Patients And Methods: Materials and Methods: Time studies are used to assess the objective workload of physicians, by measuring the duration of physicians' activities, and the WISN method, which is based on the workload of a health care professional and determines how many health care professionals of a certain type are needed to cope with the workload of a given health care facility.
Mathematical modeling of Ethiopia's energy demand by sectors and energy types, with forecasts for the next 30 years.
Heliyon
November 2024
Ministry of Water and Energy, Addis Ababa, Ethiopia.
Article Synopsis
- The study focuses on optimizing energy supply and demand in Ethiopia, recognizing the need to avoid shortages or surpluses of energy by projecting future requirements accurately.
- A mathematical model was created using data from the past fifteen years, employing linear and multilinear regression techniques, to analyze energy consumption trends in relation to factors like GDP, population growth, and urbanization.
- The results forecast energy demand scenarios up to 2052 based on different GDP growth rates, validating the model's effectiveness through comparison with actual trends.
