Moreover, the down-regulation of RAB8A could attenuate the increase in trophoblast cell proliferation, migration, invasion and glucose uptake induced by miR-30d-5p functional inhibitor. These data imply that miR-30d-5p expression is down-regulated in placental tissue from GDM patients and affects trophoblast cell functions by targeting RAB8A, which may provide new insight into the pathogenesis of GDM.Traumatic brain injury (TBI) is defined as a disturbance in brain functioning caused by an external force. The development of post traumatic epilepsy (PTE) is a serious risk associated with TBI. Indeed, other neurological impairments are also common following TBI. In this review, we analyze and discuss the most widely used and best validated rodent models of TBI, with a particular focus on their contribution to the understanding of the PTE development. Furthermore, we explore the importance of these models for the study of other neurobehavioral comorbidities associated with brain injury. The efficient and accurate diagnosis of epilepsy and other neurological comorbidities as a consequence of brain trauma should improve the survival and quality of life of patients after TBI.
Factors such as the manufacturing materials, shape or even the mechanical and thermal response of sitting Pressure Redistribution Support Surfaces (PRSS) can be potential contributors to pressure ulcers. However, few studies have compared a number of characteristics of the most frequently used devices.
To compare three potential contributors to pressure ulcers in five commercial PRSS pressure redistribution, temperature and perceived comfort.
Study with a cross-over randomized design in healthy volunteer participants. Data was collected in a temperature and relative humidity controlled environment. To assess thermal response, the temperature (Flir-E60) of the region of interest was captured before and after use of each PRSS for further analysis. The region of interest was the gluteal zone. To assess the pressure redistribution a pressure mat (XSensor®) was used between the 5 cushion and each study participant using a standardized method. Finally, a subjective perception questionnaire recorded comfort, a) seem to provide a more effective pressure relief characteristic than those injected with polyurethane foam and gel in most of the studied pressure variables. However, the cushions provide similar thermal response and perceived comfort.
Hydroxycinnamic acids their derivatives have various pharmacological properties. The hydroxycinnamic acid derivatives, methyl cinnamate, trans-cinnamic, and p-coumaric acids have been the object of study in the treatment of skin wounds. However, it is unclear whether these derivatives exert a direct beneficial effect on fibroblast function. In this study, we evaluated the effects of methyl cinnamate, trans-cinnamic, and p-coumaric acids on fibroblast migration in vitro.
NIH 3T3 and L929 fibroblast cell lines were exposed to each drug at several concentrations and the effect on cell viability, cell cycle, and extracellular matrix production were assessed by MTT assay, flow cytometry, and immunofluorescence staining, respectively. The effect on cell migration was examined using scratch assay.
The results showed that hydroxycinnamic acid derivatives not affect cell viability, but increase fibroblast migration in the in vitro scratch-wound healing assay. They also induced an increase in S and G2/M phases accompanied by a decrease in the G0/G1 phase of the cell cycle. The cell proliferation inhibitor mitomycin C abolished the effect induced by p-coumaric acid and methyl cinnamate, indicating that only the trans-cinnamic acid stimulated migration. A transwell migration assay confirmed that trans-cinnamic acid-treated fibroblasts exhibited increased migration compared with untreated cells. trans-Cinnamic acid-induced fibroblast migration was decreased by PKA inhibitor and p38-MAPK inhibitor but not by JNK inhibitor. Additionally, trans-cinnamic acid-treated fibroblasts showed an increase in the production of laminin and collagen type I.
Our study showed that trans-cinnamic acid improves fibroblast migration and modulates extracellular matrix synthesis, indicating its potential for accelerating the healing process.

However, the optimal extent of surgery remains debatable. We aimed to perform a meta-analysis of hepatectomy and no hepatectomy approaches in patients with T2 gallbladder cancer. We searched the following electronic databases for systematic literature PubMed, Google Scholar, and the Cochrane Library. We selected studies that compared patients with T2 gallbladder cancer who underwent hepatectomy with those who did not. While the long-term overall survival (OS) and disease-free survival (DFS) were the primary outcomes, perioperative morbidity and mortality were the secondary outcome. We analysed over 18 studies with 4,587 patients. Of the total patients, 1,683 and 1,303 patients underwent hepatectomy and no hepatectomy, respectively. The meta-analysis revealed no significant difference between the hepatectomy and no hepatectomy groups, in terms of the overall morbidity (risk ratio [RR] = 1.85, 95% confidence interval [CI] = 0.66-5.20) and 30-day mortality (RR = 0.9, 95% CI = 0.1-8.2). The results were comparable in terms of the OS (RR = 0.76, 95% CI = 0.57-1.01), (HR = 0.74, 95% CI = 0.49-1.12), and DFS (RR = 0.99, 95% CI = 0.88-1.11). In conclusion, the perioperative and long-term outcomes of hepatectomy and no hepatectomy approaches were comparable. Hepatectomy may not be required in T2 gall bladder cancer if the preoperative evaluation confirms the depth of the tumour in the perimuscular connective tissue and the intraoperative frozen sections confirm microscopic negative margins. GSK429286A Likewise, for those whom gall bladder cancer was diagnosed from the pathological report after simple cholecystectomy, further hepatectomy may not necessary.
