Endoplasmic reticulum (ER) stress is an imbalance between the protein-folding load and capacity of ER. It can be induced by various physiological conditions, activating the unfolded protein response (UPR) to re-establish homeostasis, promoting cell survival. Under severe or chronic stress, apoptosis is induced. Normal cells generally do not experience continuous ER stress induction. The stressful conditions experienced in the tumor microenvironment facilitate chronic ER stress and UPR activation, which plays a pivotal role in tumour survival. Exacerbation of pre-existing ER stress can trigger cancer cell death, with a minimal effect on normal cells. Bcl 2 inhibitor Current literature suggests that cannabinoid treatment may induce cancer cell death via ER stress; however, little is known about the mechanisms of induction. This study proposed that cannabidiol (CBD) mechanism occurred through the influx of Ca2+ via the TRPV1 receptor, and increasing reactive oxygen species (ROS) production affects protein folding and induces ER stress. ER stress was induced, and detection and quantification were completed using Thioflavin T staining and GRP78 by western blot analysis. The effect of cannabinoid treatment on ROS production and Ca2+ influx was measured. CBD was the most potent ER stress inducer, significantly increasing Ca2+ and ROS accumulation. Concomitant treatment with CBD and an antioxidant significantly increased cell viability and decreased ER stress induction in the MCF7 cell line. Concomitant treatment with a TRPV1 antagonist increased viability in this cell line. In conclusion, the data suggested that CBD induced ER stress via Ca2+ influx through the TRPV1 receptor, thereby elevating intracellular ROS levels and disrupting protein folding.Saturated fatty acids, whose circulating levels are markedly increased in the body, significantly affect the growth and functions of skeletal muscle. These fatty acids may exert a detrimental effect on the undifferentiated skeletal myoblasts that may adversely affect their differentiation. In the present study, the exposure of myoblasts to excess palmitic acid caused an elevation of tumor necrosis factor-α expression and an increase in reactive oxygen species levels consistent with the enhanced inflammation and oxidative stress. Various concentrations of palmitic acid significantly decreased the mitochondrial membrane potential, induced the programmed cell death by an increase in the caspase-3 expression, and DNA fragmentation in the myoblasts. These findings suggest that the increased concentrations of saturated fatty acid in the myoblasts increase lipotoxicity by increasing inflammation and oxidative stress, decreasing the mitochondrial function, and inducing apoptosis.
The primary aim was to validate the Pancreatitis Activity Scoring System (PASS) in a multicenter prospectively ascertained acute pancreatitis (AP) cohort. Second, we investigated the association of early PASS trajectories with disease severity and length of hospital stay (LOS).

Data were prospectively collected through the APPRENTICE consortium (2015-2018). AP severity was categorized based on revised Atlanta classification. Delta PASS (ΔPASS) was calculated by subtracting activity score from baseline value. PASS trajectories were compared between severity subsets. Subsequently, the cohort was subdivided into three LOS subgroups as short (S-LOS) 2-3days; intermediate (I-LOS) 3-7days; and long (L-LOS) ≥7days. The generalized estimating equations model was implemented to compare PASS trajectories.

There were 434 subjects analyzed including 322 (74%) mild, 86 (20%) moderately severe, and 26 (6%) severe AP. Severe AP subjects had the highest activity levels and the slowest rate of decline in activity (P=0.0075618).WHAT IS KNOWN ON THE SUBJECT? Mobile mental health apps are increasingly being used by both mental health nurses to promote individual self-managemental of mental health conditions and by consumers. Perceptions about specific apps are known, but the overarching acceptability and usability of mental health apps in general less understood. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE? This paper identified consumer perceptions of mobile mental health apps. Six key areas were identified that future mobile app developers should consider to maximize consumer engagement with mental health apps. Consumers also highlighted that apps do not replace traditional mental health nursing-rather these supplement existing care. WHAT ARE THE IMPLICATIONS FOR PRACTICE? This review found that mental health apps are generally viewed positively by consumers; however, factors such as ease of use, usefulness of content and privacy need to be considered to maximise and sustain app engagement. ABSTRACT Introduction There is increasing in with the app" and "Perceived issues." Consumers indicated a preference for personalization for the app to meet individual needs. Discussion and Implications for Practice Mental health apps are generally viewed positively by consumers; however, factors such as ease of use, usefulness of content and privacy need to be considered to maximise and sustain app engagement.Osteosarcomas of the jaws (OSJ) are difficult to diagnose, rare malignant lesions, with uncharacteristic radiographic and clinical presentation. Early diagnosis and treatment are essential to improve long-term prognosis. The current report presents a rare case of a primary conventional osteoblastic osteosarcoma of the anterior maxilla in a 25-year-old female. She presented to a private dental clinic after developing pain, facial oedema and palpation tenderness of a mass associated with the upper right lateral incisor. The signs and symptoms mimicked very closely a regular radiolucent and symptomatic periapical pathology, and the definitive diagnosis was only possible through a combination of clinical, radiographic and histopathological findings. The patient was referred to an oncology facility, where she was submitted to radical excision surgery through a hemi-maxillectomy. Although other pathologies are uncommon, the differential diagnosis of lesions compatible with odontogenic periapical pathology should not be neglected.
