Effects of nocturnal snacks on body composition in patients with liver cirrhosis.

Background: Patients with liver cirrhosis are universally malnourished and the nocturnal snacks intervention is the currently recommended nutritional intervention for patients with liver cirrhosis. Body composition is an important indicator for the assessment of nutritional conditions. We investigated the effects of nocturnal snacks (200 kcal/day) for 3 months on body composition in patients with liver cirrhosis.

Mechanism and efficiency research of P- and N-codoped graphene for enhanced paracetamol electrocatalytic degradation.

Electrocatalytic oxidation is an effective technology for treatment of refractory organic pollutants, and its performance strongly depends on anode materials. Among all anode materials, graphene (GN) owns the advantages of high stability and lack of secondary pollution. The catalytic performance of GN can be further improved through heteroatom doping.

[Effects of low-dose dexmedetomidine combined with hydromorphone in postoperative analgesia and on the serum IL-6 and CRP levels of prostate cancer patients].

Objective: To explore the effects of low-dose dexmedetomidine (DM) combined with hydromorphone (HM) in postoperative analgesia and on levels of serum interleukin-6 (IL-6) and C-reactive protein (CRP) in PCa patients.

Methods: Using the random number table, we divided 102 PCa patients undergoing radical prostatectomy from January 2019 to November 2020 into a trial group (n = 51) and a control group (n = 51), the former given HM and the latter low-dose DM + HM for postoperative analgesia. We recorded the postoperative resuscitation time, extubation time and pain, perioperative cognitive function, IL-6 and CRP levels, and drug-related adverse reactions of the patients, and compared them between the two groups.

[Correlation of human papillomavirus (HPV) and HPV vaccines with male reproductive health].

HPV is a very common virus worldwide spread by direct contact and involved in male reproductive health-related diseases such as infertility, condyloma acuminatum, and penile cancer. The development of HPV vaccines has contributed to the effective prevention of various subtypes of HPV and protection of males from HPV infection, especially the partners of HPV-positive females, the men who have sex with men, and those with a psychological fear of HPV infection. Therefore, HPV vaccines play an important role in the protection of males.

Sulfur doped-graphene for enhanced acetaminophen degradation via electro-catalytic activation: Efficiency and mechanism.

Although graphene exhibited excellent performance, its capability of electrochemical catalytic oxidation would significantly improve by modification via sulfur (S)-doping. However, due to the complicated doping species of heteroatoms, the detailed mechanism was still remained open for discussion. Thus, this first-attempt study tended to decipher such mechanism behind the direct and indirect oxidation by analyzing S species in S-graphene.

[Degradation of RBk5 with Peroxymonosulfate Efficiently Activated by N-Doped Graphene].

The large loss of catalysts and secondary pollution problems are bottlenecks for the utilization of persulfate advanced oxidation processes. Thus, a modified Hummers method combined with a hydrothermal method was used to prepare N-doped graphene as a catalyst for peroxymonosulfate (PMS) activation. The produced sulfate radical (SO·) and hydroxyl radical (·OH) were able to degrade RBk5.

The relationship between human papillomavirus and penile cancer over the past decade: a systematic review and meta-analysis.

Human papillomavirus (HPV) infection appears to play an important role in the development of penile cancer (PeCa), but their relationship remains unclear. Therefore, we performed a systematic review and meta-analysis to elucidate their relationship. We systematically searched Embase, PubMed, Cochrane Library, and Web of Science for case-control studies and cross-sectional studies using polymerase chain reaction (PCR) technology on formalin-fixed paraffin-embedded (FFPE) or paraffin-embedded (PE) PeCa tissues to detect HPV (published between January 1, 2007, and December 29, 2017; no language restrictions).

Diagnostic Performance of Gallium Labelled Prostate-Specific Membrane Antigen Positron Emission Tomography/Computed Tomography and Magnetic Resonance Imaging for Staging the Prostate Cancer with Intermediate or High Risk Prior to Radical Prostatectomy: A Systematic Review and Meta-analysis.

Purpose: To compare the diagnostic efficiency of Gallium labelled prostate-specific membrane antigen positron emission tomography (Ga-PSMA PET) and magnetic resonance imaging (MRI) for staging the lymph node metastases (LNMs) in the prostate cancer.

Materials And Methods: A broad search of scientific databases including PubMed, EMBASE, Web of Science, Cochrane Database, and Chinese Biomedicine Literature Database (updated prior to November 1st, 2018) was conducted systematically by two reviewers. In this paper, we evaluated the methodological quality of each included article independently and performed a systematic review and meta-analysis to reveal the summary of the diagnostic performance of Ga-PSMA PET and MRI in properly identifying LNMs of intermediate- and/or high-risk prostate cancer.

Catalytic performance and mechanism of graphene electrode doped with S and N heteroatoms for N-(4-hydroxyphenyl)ethanamide electrochemical degradation.

As operation performance of electro-oxidation is strongly influenced by feature of anode materials, apparently oriented preparation of electrode materials to maximize stable degradation efficiency would be top-priority consideration for system optimization. Recently, heteroatoms hybrid graphene is well known as one of major matrices popularly constructed onto anode modification due to its excellent electronic properties and long-term operation stability. The novelty focused on the first proposed competitive interactions between N and S species on graphene edges for improving operation efficiency.

Exposure to silica nanoparticles causes reversible damage of the spermatogenic process in mice.

Environmental exposure to nanomaterials is inevitable, as nanomaterials have become part of our daily life now. In this study, we firstly investigated the effects of silica nanoparticles on the spermatogenic process according to their time course in male mice. 48 male mice were randomly divided into control group and silica nanoparticle group with 24 mice per group, with three evaluation time points (15, 35 and 60 days after the first dose) per group.
