Geniposide alleviates heart failure with preserved ejection fraction in mice by regulating cardiac oxidative stress via MMP2/SIRT1/GSK3β pathway.

Heart failure with preserved ejection fraction (HFpEF) is a complex clinical syndrome with cardiac dysfunction, fluid retention and reduced exercise tolerance as the main manifestations. Current treatment of HFpEF is using combined medications of related comorbidities, there is an urgent need for a modest drug to treat HFpEF. Geniposide (GE), an iridoid glycoside extracted from Gardenia Jasminoides, has shown significant efficacy in the treatment of cardiovascular, digestive and central nervous system disorders.

Factors influencing spiritual wellbeing among pancreatic ductal adenocarcinoma patients receiving chemotherapy.

Background: Spiritual wellbeing emphasizes optimistic and positive attitudes while self-regulating negative emotions when coping with stress. However, there have only been a few small studies of spiritual wellbeing of pancreatic ductal adenocarcinoma (PDAC) patients undergoing chemotherapy. The core factors influencing spiritual wellbeing in this clinical population are still unclear.

Responses of the tree peony (Paeonia suffruticosa, Paeoniaceae) cultivar 'Yu Hong' to heat stress revealed by iTRAQ-based quantitative proteomics.

Horticulture productivity has been increasingly restricted by heat stress from growing global warming, making it far below the optimum production capacity. As a popular ornamental cultivar of tree peony, Paeonia suffruticosa 'Yu Hong' has also been suffering from heat stress not suitable for its optimal growth. To better understand the response mechanisms against heat stress of tree peony, investigations of phenotypic changes, physiological responses, and quantitative proteomics were conducted.

Dipeptidyl peptidase-4 (DPP4) inhibitor sitagliptin alleviates liver inflammation of diabetic mice by acting as a ROS scavenger and inhibiting the NFκB pathway.

As a common chronic metabolic disease, the development of diabetes mellitus (DM) may also be accompanied by liver damage and inflammatory disorders. Sitagliptin is an inhibitor of dipeptidyl peptidase-4 (DPP4, also known as CD26), which is clinically used for DM treatment. However, the mechanism of sitagliptin's efficiency in liver diseases is largely unknown.

Upregulation of GABA receptor promotes long-term potentiation and depotentiation in the hippocampal CA1 region of mice with type 2 diabetes mellitus.

Type 2 diabetes mellitus (T2DM) is a long-term metabolic disorder characterized by high blood sugar levels, insulin resistance and a relative lack of insulin. A previous study has reported that an association exists between γ-aminobutyric acid (GABA) and the hippocampus. The current study therefore aimed to assess the effect of the GABA receptor (GABA-R) on the long-term potentiation (LTP) and depotentiation of the hippocampal CA1 region in mice with T2DM.

Long intergenic noncoding RNA p21 suppresses the apoptosis of hippocampus neurons in streptozotocin-diabetic mice by sponging microRNA-221 through upregulation of FOS.

Diabetes is associated with neurological complications, and accumulated evidence shows that biological pathways in diabetes are targeted by noncoding RNA transcripts. In this study, the role of long intergenic noncoding RNA (lincRNA) p21/microRNA-221 (miR-221)/fructooligosaccharide (FOS) axis was investigated in the mice with diabetes treatment. The streptozotocin-induced diabetic mouse model was established.

Are nurses prepared to manage cancer pain? A national survey of nurses' knowledge about pain control in Taiwan.

Nurses play a crucial role in cancer pain control, but little is known about how well-prepared nurses are to manage cancer pain in Taiwan. The purpose of this study was to examine the level of knowledge about pain management among Taiwanese nurses with different background characteristics and to determine the predictor(s) of nurses' pain management knowledge. Nurse subjects were recruited by a cross-sectional nationwide survey with stratified sampling from nine hospitals distributed in the four major geographic regions of Taiwan.

Relationship between pain-specific beliefs and adherence to analgesic regimens in Taiwanese cancer patients: a preliminary study.

This pilot cross-sectional study aimed to 1) explore pain beliefs and adherence to prescribed analgesics in Taiwanese cancer patients, and 2) examine how selected pain beliefs, pain sensory characteristics, and demographic factors predict analgesic adherence. Pain beliefs were measured by the Chinese version of Pain and Opioid Analgesic Beliefs Scale-Cancer (POABS-CA) and the Survey of Pain Attitudes (SOPA). Analgesic adherence was measured by patient self-report of all prescribed pain medicine taken during the previous 7 days.
