Glioma is the most common human central nervous system tumour with a high degree of malignancy. Some Rab GTPases have significant effects on glioma.

This study aimed to investigate the effect of Rab3b (Rab GTPase3b) on human glioma cell proliferation and apoptosis by silencing Rab3b and to initially verify the value of Rab3b expression for the diagnosis and progression in human glioma.

Rab3b was silenced by siRNA transfection. Human glioma tissues and normal brain tissues adjacent to glioma were obtained by surgery. Rab3b, P53, Caspase 7, Bax, and Bim mRNA and protein expression levels were detected by quantitative real-time polymerase chain reaction (qRT-PCR) and Western blotting. see more Cell proliferation was detected by the cell counting kit-8 assay, and the cell cycle and apoptosis were analysed using flow cytometry.

Rab3b mRNA and protein expression in human glioma U251 and U87 cells was significantly downregulated after Rab3b silencing. Rab3b silencing inhibited glioma cell proliferation by promoting cn levels of apoptosis-related proteins, however these preliminary in vitro results warrant validation on in vivo studies.Mucoadhesive formulations have been demonstrated to result in efficient drug delivery systems with advantages over existing systems such as increased local retention and sustained drug release via adhesiveness to mucosal tissues. The controlled release of colon-targeted, orally administered drugs has recently attracted a number of studies investigating mucoadhesive systems. Consequently, substantial designs, from mucoadhesive cores to shells of particles, have been studied with promising applications. This review will provide an overview of specific strategies for developing mucoadhesive systems for colon-targeted oral delivery with controlled drug release, including mucoadhesive matrices, cross-linked mucoadhesive microparticles, coatings and mucoadhesive nanoparticles. The understanding of the basic principle of these designs and advanced formulations throughout will lead to the development of products with efficient drug delivery at the colon for therapies for different diseases.Alzheimer's Disease (AD) is one of the most prevalent age-related neurodegenerative diseases that affect the cognition, behavior, and daily activities of individuals. Studies indicate that this disease is characterized by several pathological mechanisms, including the accumulation of amyloid beta peptide, hyperphosphorylation of tau protein, impairment of cholinergic neurotransmission, and increase in inflammatory responses within the central nervous system. Chronic neuroinflammation associated with AD is closely related to disturbances in metabolic processes, including insulin release and glucose metabolism. As AD is also called type III diabetes, diverse compounds having antidiabetic effects have been investigated as potential drugs for its symptomatic and disease-modifying treatment. In addition to insulin and oral antidiabetic drugs, scientific attention has been paid to cyclic-3',5'-adenosine monophosphate (cAMP)-specific phosphodiesterase (PDE) inhibitors that can modulate the concentration of glucose and related hormones, and exert beneficial effects on memory, mood, and emotional processing. In this review, we present the most recent reports focusing on the involvement of cAMPspecific PDE4, PDE7, and PDE8 in glycemic and inflammatory response controls as well as the potential utility of the PDE inhibitors in the treatment of AD. Besides the results of in vitro and in vivo studies, the review also presents recent reports from clinical trials.Background The overall changes of ocular motility in Graves' orbitopathy (GO) are not easily quantifiable with the methods currently available, especially in clinical studies. The aim of the present study was to calculate parameters that quantify the changes of ocular motility in GO in relation to the Gorman score for diplopia. Methods We studied 100 GO patients (Group 1) and 100 controls (Group 2). We also included 30 patients treated with intravenous methylprednisolone (iv-MP), assessed at baseline and after 12 and 24 weeks (Group 3), and 66 patients submitted to squint surgery, assessed at baseline and after 12 weeks (Group 4). Ocular ductions were measured in four gaze directions by a perimeter arc and were used to calculate a total motility score (TMS) as the sum of ductions in each direction; a biocular TMS (b-TMS) as the sum of the TMS of two eyes; and an asymmetry ratio (AR) as the sum of the differences of the corresponding ductions between the two fellow eyes divided by the mean difference found in controls. Quality of life was accessed by a specific questionnaire (Graves' orbitopathy quality of life [GO-QoL] questionnaire). Results TMS and b-TMS were lower, while AR was higher, in Group 1 compared with controls (p  less then  0.001). In Group 1, TMS and b-TMS were inversely correlated with the Gorman score (p  less then  0.001) and AR was higher in patients with constant diplopia compared with the others (p  less then  0.001). In Group 3, TMS and b-TMS increased after treatment in responders to iv-MP (p  less then  0.001). In Group 4, TMS and b-TMS improved in all patients after surgery (p  less then  0.01), while AR and GO-QoL score improved only in those without residual constant diplopia (p  less then  0.001). Conclusion We describe a quantitative method to assess eye motility dysfunction in any stage of GO to be used as an outcome measure in clinical studies.Language provides cadences of sounds, silences, and movements that bring to light meaning, which in turn transforms human connections, understanding, and knowledge. When coupled with disciplinary knowledge and opportunities to illuminate with simulation, there are opportunities to influence human connectedness, which is meaningful even in times of a pandemic.At times of perceived rapid and significant change, such as the world has experienced with the current COVID-19 pandemic, the unrepeatable ebb and flow of the paradoxical rhythms inherent in humanuniverse patterning seem to come to the forefront of awareness. What was previously known and familiar seemingly disintegrated in the emergence of the unfamiliar experience of a global quarantine. While difficulties abounded across the discipline of nursing, these challenges created new opportunities for visioning anew in thinking beyond the restrictions of the COVID-19 pandemic. A challenge is presented to nurse administrators and faculty charged with preparing the next generation of nurses to meet the challenges of an unknowable future by thinking beyond the traditional boundaries of classroom and clinic to co-create new ways of living the teaching-learning mission of nurse education programs.
