Alzheimer's disease (AD) is the most common cause of dementia, and it exhibits pathological properties such as deposition of extracellular amyloid β (Aβ) and abnormally phosphorylated Tau in nerve cells and a decrease of synapses. Conventionally, drugs targeting Aβ and its related molecules have been developed on the basis of the amyloid cascade hypothesis, but sufficient effects on the disease have not been obtained in past clinical trials. On the other hand, it has been pointed out that chronic inflammation and microbial infection in the brain may be involved in the pathogenesis of AD. Recently, attention has been focused on the relationship between the periodontopathic bacterium and AD. and its toxins have been detected in autopsy brain tissues from patients with AD. In addition, pathological conditions of AD are formed or exacerbated in mice infected with . Compounds that target the toxins of ameliorate the pathogenesis of AD triggered by infection. These findings indicate that the pathological condition of AD may be regulated by controlling the bacteria in the oral cavity and the body. In the current aging society, the importance of oral and periodontal care for preventing the onset of AD will increase.

The evolution of body weight under the natural trypanosome challenge and its association with disease tolerance to trypanosomosis is of utmost economic importance in cattle. This study estimated heritability for growth traits and packed cell volume (PCV) and their genetic correlations in the N'Dama cattle in the Gambia. A total of 2,488, 2,442, 1,471, 1,934, and 1,452 bodyweight records at 12 months (WT12), 16 months (WT16), 18 months (WT18), 24 months (WT24), 36 months (WT36) and 50 months (WT50) and 1,782, 1,800, 1,844, 1,608, and 1,459 records for PCV at 12 months (PCV12) 18 months (PCV18), 24 months (PCV24), 36 months (PCV36), and 50 months (PCV50), respectively, were analysed.

Background: The high burden of malaria in Africa is largely due to the presence of competent and adapted Anopheles vector species. With invasive Anopheles stephensi implicated in malaria outbreaks in Africa, understanding the genomic basis of vector-parasite compatibility is essential for assessing the risk of future outbreaks due to this mosquito. Vector compatibility with P.

Nanomaterials have been shown to promote crop growth, yield and stress resistance. Carbon nanosol (CNS), a type of nanomaterial, is used to regulate tobacco shoot and root growth. However, information about the application of CNS to crop plants, especially tobacco, is still limited.

Background: In observational studies, frailty has been strongly associated with mental disorders. However, the mechanisms underlying the association between frailty and mental disorders remain unclear.
Methods: We conducted a two-sample Mendelian randomization (MR) study to assess the causal relationship between frailty, as measured by the frailty index (FI), and ten common mental disorders.

Background And Aim: Recent Mendelian randomization and meta analysis suggest a controversial causality between C3-epimer of 25 hydroxyvitamin D3 (C3-epi-D3) and type 2 diabetes mellitus (T2DM). The clinical evidence regarding the impact of C3-epi-D3 on the progression of T2DM is currently insufficient. This study aims to investigate whether C3-epi-D3 has any effect on metabolic disorders of T2DM patients.
