This study aimed to assess lower limb strength and some related factors among older people with dementia examined and treated at the National Geriatric Hospital. Three-quarters of older dementia patients have impaired lower limb strength. Our results highlighted that diabetes, and geriatric syndromes such as malnutrition, high fall risk, dependence, and partial dependence were significantly associated with lower limb strength in older patients with dementia.

Ovarian cancer (OC) is a gynecological malignancy tumor with high recurrence and mortality rates. Programmed cell death (PCD) is an essential regulator in cancer metabolism, whose functions are still unknown in OC. Therefore, it is vital to determine the prognostic value and therapy response of PCD-related genes in OC.

Tumor morphology, immune function, inflammatory levels, and nutritional status play critical roles in the progression of intrahepatic cholangiocarcinoma (ICC). This multicenter study aimed to investigate the association between markers related to tumor morphology, immune function, inflammatory levels, and nutritional status with the prognosis of ICC patients.

Lung cancer significantly impairs exercise capacity and health-related quality of life (HRQL). Pulmonary rehabilitation (PR) has demonstrated positive effects on exercise capacity and HRQL in lung cancer patients. However, its impact on cardiopulmonary function needs further exploration. The aim of this study was to explore the effects of PR on cardiopulmonary function, exercise capacity and HRQL in patients with lung cancer.

This study aims to identify functionally relevant lncRNAs impacting OS proliferation and lipid metabolism and seeks to shed light on the upstream regulatory mechanisms governing lipogenic enzyme activity. Based on comprehensive bioinformatic analysis and the establishment of a risk model, we identified seven lncRNAs signifcantly associated with clinical characteristics and lipid metabolism-related genes in patients with OS.

This paper investigates the nonlinear vibration of saturated porous functionally graded plate subjected to the combination of mechanical and thermal loadings. Three different distributions of porosity are considered. Based on the Biot and higher order shear deformation theories, the vibration characteristics including natural frequency, deflection amplitude – time curves and relation between frequency ratio and amplitude of the saturated porous plate are determined.

The primary aim of Cerebral Signal Transduction: From First to Fourth Messengers, therefore, is to offer a comprehensive picture of the recent advances made in the signaling field as it relates to neuronal and cere bral function. The current state of progress provides an exciting opportunity for such a comprehensive focus because molecular tools have become available to selectively remove, reduce, or enhance spe cific components in the signaling pathways, e. g. , by interfering with the genes encoding key proteins.

This groundbreaking work explores media scholar Sut Jhally's thesis that advertising functions as a religion in late capitalism and relates this to critical theological studies. Sheffield argues that advertising is not itself a religion, but that it contains religious dimensions - analogous to Durkheim's description of objects as totems.

The linear buckling behavior of functionally graded toroidal shell segments with corrugated core under axial compression using the first-order shear deformation theory is presented in this paper. The homogeneous technique is applied for shear deformable corrugated core. Approximate analytical solutions are assumed to satisfy the simply supported boundary conditions and the adjacent equilibrium criterion is applied to obtain closed-form relations of buckling loads.

In the paper "Nonlinear static analysis of bidirectional functionally graded sandwich plates using a higher-order finite element formulation" the nonlinear static behaviors of bidirectional functionally graded sandwich (BFGSW) plates are investigated using a finite element procedure. The plates consist of three layers, a homogeneous core and two bidirectional functionally graded face sheets. A nonlinear finite element formulation in sense of the von Karman nonlinear strain-displacement relation is derived in the basis of a higher-order shear deformation theory.

The article analyzes significant changes that have taken place in the development of the rural sector of Ukraine by sustainable supply chain development, which includes two components: agrarian (agriculture and technologically related industries) and rural areas (spatial base of production and resettlement of the population) of the second half of the last century. Current problems are revealed and the prospects of the rural sector functioning, through the prism of different concepts of productive forces development, are outlined.
