We tested our hypothesis that Myc-interacting zinc finger protein 1 (MIZ1), a cell cycle regulator, suppressed inflammation, and therefore, represented a useful prognostic marker in patients with acute necrotizing pancreatitis (ANP) complicated by acute lung injury.

Nicotine, the major component of cigarette smoke, has been reported to promote pancreatic ductal adenocarcinoma (PDAC) growth and invasion. Deregulation of microRNA (miRNA) expression is found in many cancers, including PDAC. The effects of nicotine on miRNAs change in PDAC progression remain unknown.

Nicotine promotes tumor progression and epithelial-mesenchymal transition by regulating the miR-155-5p/NDFIP1 axis in pancreatic ductal adenocarcinoma.

Colonoscopy is effective in the prevention and screening of colorectal cancer. Whether terminal ileal (TI) intubation is required during conventional colonoscopy and whether it offers clinical benefits with respect to polyp detection rate (PDR) remain unclear. This retrospective study included patients who underwent colonoscopy at our hospital between July 1, 2018 and April 20, 2019. The positive findings and time for TI intubation were recorded. Univariate and multivariate analyses were performed to identify factors associated with PDR. There were 1675 patients with cecal intubation colonoscopy, including 994 (59 %) with TI intubation and 8 (1 %) with intestinal disease. The mean time for TI intubation was 40 seconds (3-338), and the mean time from cecal intubation to arrival at the deep part of TI mucosa was 24 seconds (2-118). The overall PDR was 27 %. On multivariable analysis, age > 50 years [95 % confidence interval (CI) 2.837-4.590], male sex (95 %CI, 0.406-0.649), presence of symptoms (abdominal symptoms vs. asymptomatic, 95 % CI, 1.146-2.468; stool changes vs. asymptomatic, 95 % CI, 1.070-1.834), and non-TI intubation (95 % CI, 1.040-1.648) were independent predictors of higher PDR. Trend analysis indicated decreasing trend of PDR among non-TI intubation group, 0-5 cm TI intubation group, and > 5 cm TI intubation group (30 % vs. 27 % vs. 24 %, respectively; p < 0.05). TI intubation is necessary to identify small bowel disease among a designated population, but it was not suggested to be routinely performed as part of colonoscopy, owing to limited positive intestinal findings, extra time requirement, and possible PDR worsening.

Routine ileal intubation in colonoscopy does not increase the polyp detection rate: a retrospective study.

Accumulating data support that regular physical activity potentially inhibits chronic colitis, a risk factor for colitis-associated cancer (CAC). However, possible effects of physical activity on CAC and the underlying mechanisms remain poorly understood.

Easy recurrence and bacteria infected-wound healing after surgery excision pose severe challenges to clinical melanoma therapy. Herein, an injectable CuO nanodots-engineered thermosensitive chitosan hydrogel (CuO-BSO@Gel) for enhanced melanoma chemo-sonodynamic therapy and improved infected wound healing was rationally constructed by facilely integrating the CuO nanodots and L-Buthionine-(S, R)-sulfoximine (BSO) with thermoresponsive hydrogel. Favored by the Fenton catalytic activity of Cu, the CuO nanodots can achieve enhanced chemodynamic therapy (CDT) by self-supplying HO under acidic tumor microenvironment. Simultaneously, the CuO nanodots with a narrow bandgap (2.29 ​eV) were proven to be the efficient sonosensitizers, and the corresponding quantum yield of singlet oxygen (O) could be boosted by the O generation during Fenton-like reactions. Additionally, combining with the glutathione (GSH) depletion of loaded BSO, intracellular oxidative stress induced by SDT and CDT was further amplified, leading to the specific ferroptosis. Importantly, this multifunctional hydrogel significantly promoted the proliferation of normal skin cells and accelerated the bacteria-infected wound healing by the effective chemo-sonodynamic antibacterial activity and the enhanced angiogenesis. Thus, the engineered thermogel features the distinct chemo-sonodynamic performance, desirable biocompatibility and bioactivity, providing a competitive strategy for eradicating melanoma and infected wound healing.

Gallstone disease (GSD) is a major public health problem worldwide. The dietary inflammatory index (DII) and the energy-adjusted DII (E-DII) have been used to describe dietary inflammatory potential. The current study sought to investigate the pro-inflammatory role of diet on GSD among outpatients in the United States.

Acute pancreatitis (AP) ranks among the most frequently encountered gastrointestinal diseases in the emergency department. Recent studies have increasingly emphasized the substantial connection among gut microbiota, inflammatory cytokines, and AP.

Synaptic loss strongly correlates with cognitive impairment in Alzheimer's disease (AD), yet the mechanism linking its origin and pattern remain unclear. Given that connected brain regions share molecular and synaptic features, and pathological tau, a key driver of synaptic degeneration, propagates through brain networks, we hypothesize that network architecture may influence synaptic loss in AD. By combining synaptic vesicle glycoprotein 2 A (SV2A) PET in 91 AD patients and 54 controls with normative connectome data, we show strongly connected regions exhibit similar levels of synaptic loss, and synaptic loss in one region is associated with connectivity-weighted synaptic loss in connected regions. Regions strongly connected to the epicenter show greater and faster synaptic loss. Plasma p-tau181 levels correlate with network-constrained synaptic loss, and post-mortem data confirm reduced SV2A expression in tau-rich areas. These findings support that synaptic vulnerability in AD is partially constrained by network topology and is modulated by phosphorylated tau.

Synaptic loss pattern is constrained by brain connectome and modulated by phosphorylated tau in Alzheimer's disease.

All intravenous delivered nanomedicine needs to escape from the blood vessel to exert their therapeutic efficacy at their designated site of action. Failure to do so increases the possibility of detrimental side effects and negates their therapeutic intent. Many powerful anticancer nanomedicine strategies rely solely on the tumor derived enhanced permeability and retention (EPR) effect for the only mode of escaping from the tumor vasculature. However, not all tumors have the EPR effect nor can the EPR effect be induced or controlled for its location and timeliness. In recent years, there have been exciting developments along the lines of inducing endothelial leakiness at the tumor to decrease the dependence of EPR. Physical disruption of the endothelial-endothelial cell junctions with coordinated biological intrinsic pathways have been proposed that includes various modalities like ultrasound, radiotherapy, heat and even nanoparticles, appear to show good progress towards the goal of inducing endothelial leakiness. This review explains the intricate and complex biological background behind the endothelial cells with linkages on how updated reported nanomedicine strategies managed to induce endothelial leakiness. This review will also end off with fresh insights on where the future of inducible endothelial leakiness holds.
