Office employees of all ages are at risk for non-communicable diseases such as musculoskeletal disorders (MSDs) due to physical inactivity. Stretching exercise (SE) behavior could help office employees prevent MSDs. This research aimed to study the predictors of SE among office employees working in Shahid Beheshti University of Medical Sciences (SBUMS) of Iran through a health promotion model (HPM). ⋯ This study showed that the office employees who were more confident and committed to a plan of action, and perceived fewer barriers, were more likely to engage in SE behavior.

Mitochondrial and oxidative stress has been related to obesity and breast cancer being this cancer more frequent and more aggressive in postmenopausal women with obesity. ⋯ We did not find a higher frequency of mitochondrial somatic mutations in postmenopausal women with breast cancer and obesity compared to those with normal BMI. However, results could be due to the small number of women studied.

Adenosine A1 receptor (AA1R) is widely present in the central nervous system, exerting brain protective antiepileptic effects, mainly by binding corresponding G proteins. We evaluated the neuroprotective effects of AA1R on hippocampal neuronal injury after lithium chloride-pilocarpine-induced epilepsy in rats. ⋯ AA1R abated cell edema and reduced apoptosis, exerting neuroprotective effects on hippocampal neuronal injury after lithium chloride-pilocarpine-induced epilepsy.

Cancer is the second-leading cause of death in the world, accounting for one out of six deaths. Consequently, there is an urgent need for new and more effective therapeutic options as well as drug screening methods. Immortal, "stable" cancer cell lines have been employed since the past century to assess drug response but face several disadvantages. ⋯ Here, we provide an overview of the basic concepts underlying generation and characterization of primary cell cultures from tumor samples. We emphasize the advantages and disadvantages of using these types of cancer cell cultures, and we make a comparison with other types of cultures used for personalized therapy. Finally, we consider the use of primary cancer cell cultures in personalized therapy as a means to improve drug response prediction and therapeutic outcomes.

It has been proposed that Vitamin D helps reduce the accumulation of cerebral β-amyloid-42 by innate immune stimulation and phagocytosis activation. An association between low Vitamin D levels and Alzheimer's dementia (AD) has been established. We determined the association between Vitamin D, mild cognitive impairment (MCI), and AD in older Mexican adults (> 65 years). ⋯ Serum Vitamin D deficiency was associated with MCI and dementia; low levels produced a greater effect over executive functions.
