The Influence of the Gut Microbiota on Alzheimer's Disease: A Narrative Review.

Alzheimer's disease (AD) is a common neurodegenerative disease that tends to occur in the elderly. The main symptom is hypomnesia. More and more older people are suffering from this disease worldwide.

Corresponding risk factors between cognitive impairment and type 1 diabetes mellitus: A narrative review.

Type 1 diabetes mellitus (T1DM) is a type of diabetes caused by the destruction of pancreatic β cells and the absolute lack of insulin secretion. T1DM usually starts in adolescence or develops directly as a severe disease state of ketoacidosis. T1DM and its complications make many people suffer and have psychological problems, which make us have to pay more attention to the prevention and early control of T1DM.

[Transurethral holmium laser enucleation of the prostate for benign prostatic hyperplasia in patients with a history of transrectal prostate biopsy].

Objective: To evaluate the efficiency and safety of transurethral holmium laser enucleation of the prostate (HoLEP) in the treatment of BPH in patients with a history of transrectal prostate biopsy (TRPB).

Methods: We retrospectively analyzed the clinical data on 102 cases of BPH treated by HoLEP in our hospital between November 2015 and May 2017, of which 42 had received TRPB prior to HoLEP (the PB group) but not the other 60 (the non-TRPB ［NPB］ group). We compared the preoperative, perioperative and postoperative follow-up data between the two groups of patients.

Scorpion Venom Heat-Resistant Peptide is Neuroprotective against Cerebral Ischemia-Reperfusion Injury in Association with the NMDA-MAPK Pathway.

Scorpion venom heat-resistant peptide (SVHRP) is a component purified from Buthus martensii Karsch scorpion venom. Our previous studies have shown that SVHRP is neuroprotective in models of Alzheimer's disease and Parkinson's disease. The present study aimed to explore the potential neuroprotective effects of SVHRP on cerebral ischemia/reperfusion (I/R) injury, using a mouse model of middle cerebral artery occlusion/reperfusion (MCAO/R) and a cellular model of oxygen-glucose deprivation/reoxygenation (OGD/R).

Pathological and cognitive changes in patients with type 2 diabetes mellitus and comorbid MCI and protective hypoglycemic therapies: a narrative review.

Type 2 diabetes mellitus (T2DM) is becoming a significant health issue worldwide. Many studies support the hypothesis that patients with T2DM have a higher-than-expected incidence of mild cognitive impairment (MCI) than individuals without diabetes. Based on the results from recent studies, MCI might be associated with the effects of T2DM on glucose metabolism and brain atrophy.

[Species composition, structure and spatial distribution of secondary cold-temperate Picea forest in Guandi Mountain, China].

The secondary Picea forest is one of the dominant vegetation types in Guandi Mountain. It's also the representative type of evergreen cold-temperate coniferous forests in subalpine region of north China. A 4 hm fixed monitoring Picea forest plot was established in Pangquangou Nature Reserve, Guandi Mountain (GDS plot) to better understand the basic characteristics such as species composition, community structure and its potential ecological process and mechanisms.

Mild cognitive impairment in type 2 diabetes mellitus and related risk factors: a review.

Type 2 diabetes mellitus (T2DM) is a global epidemic disease and has become a significant health problem. Many studies have raised concern about the mild cognitive impairment (MCI) with T2DM and even the Alzheimer's disease patients with T2DM. The incidence of MCI is higher in individuals with T2DM than those without diabetes.

Correlation between chronic headaches and the rectus capitis posterior minor muscle: A comparative analysis of cross-sectional trail.

Objective We aimed to investigate the morphological changes and potential correlation between chronic headaches and the rectus capitis posterior minor muscle (RCPmi). Methods Comparison of RCPmi between patients with chronic headaches and healthy adult volunteers were collected using magnetic resonance imaging (MRI) and Mimics software. Results Among the 235 MRI images analyzed, the data between the two groups were considered statistically significant.

Contribution of AM inoculation and cattle manure to lead and cadmium phytoremediation by tobacco plants.

Lead and cadmium are both highly toxic pollutants and pose potential risks to the environment and human health. Arbuscular mycorrhizal (AM) inoculation and organic amendments may make a potential contribution to phytoremediation of these toxic metals, but their effects remain unclear. We conducted a pot culture experiment to study the contribution of AM inoculation and/or cattle manure to phytoremediation of two soils artificially polluted with 0, 350, 500 and 1000 mg Pb per kg soil or 0, 1, 10, 100 mg Cd per kg soil using tobacco plants.

The effect of erbium on the adsorption and photodegradation of orange I in aqueous Er3+-TiO2 suspension.

Pure TiO(2) and erbium ion-doped TiO(2) (Er(3+)-TiO(2)) catalysts prepared by the sol-gel method were characterized by means of XRD and diffusive reflectance spectra (DRS). The XRD results showed that erbium ion doping could enhance the thermal stability of TiO(2) and inhibit the increase of the crystallite size, and the DRS results showed that the optical absorption edge slightly shifted to red direction owing to erbium ion doping and the Er(3+)-TiO(2) catalysts had three typical absorption peaks located at 490, 523 and 654 nm owing to the transition of 4f electron from (4)I(15/2) to (4)F(7/2), (2)H(11/2) and (4)F(9/2). With a purpose of azo dyes degradation, orange I was used as a model chemical.
