Background: Given the stigma and fear associated with Alzheimer’s disease (AD), combined with the progressive nature of the disease, the diagnosis of AD or mild cognitive impairment (MCI) is often very difficult; yet, there may still be ways to experience some positive outcomes following diagnosis. We aim to assess the psychological impact of a diagnosis of MCI or early dementia on positive well-being. Methods: Individuals with a diagnosis of MCI or AD were mailed surveys with the Silver-Lining Questionnaire. Resul [...]

The total lack of spermatozoa in the ejaculate is known as Azoospermia. It is the most severe and significant contributor to male infertility. Therefore, the purpose of this study is to assess the status of Azoospermia and its etiologic factors that contribute to male infertility in Saudi Arabia. This study included all published studies written in English that were published in Saudi Arabia. Online searches via PubMed and Google Scholar were conducted from their inception to 15 January 2023. A total of 624 studies [...]

The research described the production and characterization of various materials, particularly alpha-alumina ceramic supports, zeolite SAPO-34, and zeolite membranes. Ceramic supports were manufactured through dry uniaxial compaction. Sintering of the supports was carried out at 1300°C for 2 h. SAPO-34 zeolites and zeolite membranes were synthesized through a hydrothermal process involving two steps: a first step at 38°C for 24 h and a second step at 200°C for 24 h. The research aimed to determine how different sili [...]

Robertsonian translocations (RTs) are very common balanced structural chromosome rearrangements in humans. Due to alterations in the chromosome segregation pattern and the formation of unbalanced gametes and embryos, the carriers of RTs have a significant risk of reproductive failure. For over 30 years, fluorescent in situ hybridization (FISH) has been used for preimplantation genetic testing for chromosomal structural rearrangement (PGT-SR) in carriers of RTs. The data obtained by performing FISH for PGT-SR can be [...]

Inadequate sleep is a largely under recognised problem in Australia despite researchers consistently highlighting it as a key component of health and wellbeing. Over a third of Australian adults now experience some form of inadequate sleep, which is consistently linked to a range of accompanying physical and mental health concerns. In addition to the health burden on the individual, the associated financial burden incurred by the community is extremely high with inadequate sleep costing over 66.3 billion annually i [...]

Stress in teaching leads to many teachers suffering from burnout or leaving the profession. Therefore, it is important to identify specific correlates of teacher stress. The role of student age and social-emotional competence in teacher stress emergence is still unclear To further clarify this relationship, 284 teachers were surveyed using a questionnaire that measured teacher stress, student year grade, and student social-emotional competence. Results show a strong negative relationship between grade level and tea [...]

The ketogenic diet (KD) is currently well known in the lay media as a quick way to lose weight. However, the KD is not a new medical concept. The KD was used in the early 1900s to control seizures. However, as we developed more effective pharmacological agents, we used the KD less until it became practically obscure by the 1980s. Similar to the effects of fasting, the KD leads to the production of ketones as an alternative energy source to glucose. Therefore, the KD has many beneficial metabolic effects, such as an [...]

This article explores the adaptation process of older adults in residential care facilities in New Zealand. Through a phenomenological approach, this study provides clarity on how older adults adjust in residential care despite losses and challenges. Qualitative data on 24 older adults, 6 residential care facilities, and 10 staff were collected. Utilising qualitative software the following were identified: loss, support, acceptance and meaningful support. Initially, the unfamiliar environment and faces, structured [...]

The high carbon footprint of cement production and the cost and environmental impact of steel reinforcement make conventional concrete unsustainable for long-term use. Reducing cement consumption and identifying sustainable, cost-effective alternatives to steel are critical for lowering construction’s ecological and economic burden. Bio-based supplementary cementitious materials (SCMs), such as rice husk ash (RHA), and natural plant fibers show promise, but prior studies have mostly tested them separately or with v [...]
