Background: Despite the availability and benefits of the Human papillomavirus (HPV) vaccine, parental acceptance remains low in the eastern mediterranean region (EMR). Therefore, this meta-analysis aimed to estimate the pooled proportion of parental uptake and willingness to vaccinate their children with the HPV vaccine and their determinants in the EMR.

Methods: We searched PubMed Central, PubMed Medline, Scopus, Web of Science, ProQuest, Google Scholar, and medRxiv according to PRISMA guidelines until the 5th of April 2024.

Nutritional epidemiology aims to link dietary exposures to chronic disease, but the instruments for evaluating dietary intake are inaccurate. One way to identify unreliable data and the sources of errors is to compare estimated intakes with the total energy expenditure (TEE). In this study, we used the International Atomic Energy Agency Doubly Labeled Water Database to derive a predictive equation for TEE using 6,497 measures of TEE in individuals aged 4 to 96 years.

Olanzapine (OLZ) is a commonly prescribed drug for the treatment of schizophrenia and related disorders. However, OLZ use is associated with several adverse effects, including decreased locomotor activity and increased body weight. While the majority of studies have directed their focus towards managing the metabolic side effects of OLZ, there has been limited attention given to the effects on locomotor activity.

Article Synopsis
  • Doubly labeled water is the most reliable method for measuring total energy expenditure (TEE), but its accuracy can be affected by the isotope dilution space ratio (DSR).
  • This study explored factors like age, sex, ethnicity, body composition, and geographical elevation to see how they influence DSR, using various statistical analysis methods.
  • Results showed that while DSR decreased with age in individuals 60 and older, no significant effects were found from other variables, suggesting that previous estimates of TEE might be overestimating values for older individuals, especially those around 90 years old.

The recognition of core promoter sequences by TFIID is the first step in RNA polymerase II (Pol II) transcription initiation. Metazoan holo-TFIID is a trilobular complex, composed of the TATA binding protein (TBP) and 13 TBP-associated factors (TAFs). Why and how TAFs are necessary for the formation of TFIID domains and how they contribute to transcription initiation remain unclear.

Objective: Kienböck disease is a rare condition characterized by severe pain and restricted wrist movement. Various palliative methods have been proposed as therapeutic strategies for alleviating symptoms. Mesenchymal stromal cell transplantation has been suggested as an innovative and promising approach due to its potential for inducing regeneration and immunomodulation in the necrotic tissue.

The recognition of core promoter sequences by the general transcription factor TFIID is the first step in the process of RNA polymerase II (Pol II) transcription initiation. Metazoan holo-TFIID is composed of the TATA binding protein (TBP) and of 13 TBP associated factors (TAFs). Inducible knock out (KO) results in the formation of a Taf7-less TFIID complex, while KO leads to serious defects within the TFIID assembly pathway.

There is considerably greater variation in metabolic rates between men than between women, in terms of basal, activity and total (daily) energy expenditure (EE). One possible explanation is that EE is associated with male sexual characteristics (which are known to vary more than other traits) such as musculature and athletic capacity. Such traits might be predicted to be most prominent during periods of adolescence and young adulthood, when sexual behaviour develops and peaks.

Multiple sclerosis (MS) is a progressive, demyelinating neurodegenerative disease of the central nervous system. MS is immune-mediated and leads to disability especially in young adults. Even though 18 MS therapy drugs were approved, they slightly inhibit disease progression and do not induce regeneration and repair in the nervous system.

Obesity is caused by a prolonged positive energy balance. Whether reduced energy expenditure stemming from reduced activity levels contributes is debated. Here we show that in both sexes, total energy expenditure (TEE) adjusted for body composition and age declined since the late 1980s, while adjusted activity energy expenditure increased over time.

Introduction: The use of cisplatin in clinical practice in the management of head and neck squamous cell carcinoma (HNSCC) is limited by its toxicity and acquired resistance, which makes the decision-making process of its prescription multifactorial.

Methods: An Egyptian expert panel (comprising nine Egyptian oncologists) meeting was held after a comprehensive literature review on the use of cisplatin in HNSCC. The panel aimed to develop a consensus on evidence-based recommendations for receiving cisplatin in the chemoradiotherapy management of HNSCC in Egyptian clinical practice.

Article Synopsis
  • * A study using different levels of ozone concentration found decreased uptake of essential minerals like calcium, magnesium, iron, zinc, sodium, and potassium by roots, with specific differences in how these minerals were allocated between roots and shoots.
  • * Although chronic ozone exposure influenced mineral uptake and distribution, it did not significantly change total carbon and nitrogen concentrations in leaves or roots, with only minor changes such as reduced lignin in leaves at the highest ozone level.

Understanding the impacts of activity on energy balance is crucial. Increasing levels of activity may bring diminishing returns in energy expenditure because of compensatory responses in non-activity energy expenditures. This suggestion has profound implications for both the evolution of metabolism and human health.
