Abundance and characteristics of microplastics in the Wanquan River estuary, Hainan Island.

As the nexus where rivers and oceans meet, estuaries are vulnerable to microplastic (MP) pollution derived from rivers. However, few studies have focused on the pollution status of MPs in small estuarine areas. Here, the abundance and characteristics of MPs in surface water and sediment samples from a small estuary, the Wanquan River estuary, were studied.

An integrative investigation of developmental toxicities induced by triphenyltin in a larval coral reef fish, Amphiprion ocellaris.

Triphenyltin (TPT) is widely distributed on coastlines, which makes coral reef fish a potential target of TPT pollution. However, the negative effects of TPT on coral reef fish remain poorly understood. Therefore, in the present study, the larval coral reef fish Amphiprion ocellaris was used to investigate the developmental toxicities of TPT at environmentally relevant concentrations (0, 1, 10 and 100 ng/L).

Thymic lipofibroadenoma of the anterior mediastinum: A rare case report.

Background: Lipofibroadenoma is an extremely rare thymic tumor, and the anterior mediastinum is the most common site.

Case Summary: A 21-year-old male was admitted with fever without obvious cause for 2 months. After admission, the patient's highest temperature was 38.

Poly(I:C) preconditioning protects the heart against myocardial ischemia/reperfusion injury through TLR3/PI3K/Akt-dependent pathway.

Emerging evidence suggests that Toll-like receptors (TLRs) ligands pretreatment may play a vital role in the progress of myocardial ischemia/reperfusion (I/R) injury. As the ligand of TLR3, polyinosinic-polycytidylic acid (poly(I:C)), a synthetic double-stranded RNA, whether its preconditioning can exhibit a cardioprotective phenotype remains unknown. Here, we report the protective effect of poly(I:C) pretreatment in acute myocardial I/R injury by activating TLR3/PI3K/Akt signaling pathway.

Effects of intravenous and inhalation anesthesia on blood glucose and complications in patients with type 2 diabetes mellitus: study protocol for a randomized controlled trial.

Background: Diabetes mellitus (DM) is a metabolic disorder syndrome caused by relative or absolute lack of insulin and varying degrees of insulin resistance. The type and regimen of anesthesia may affect perioperative hyperglycemia following major surgical stress. The effect of perioperative anesthetics on the blood glucose level of diabetic patients will play an essential role in the postoperative recovery of patients.

4-Butyl-anilinium perchlorate.

In the crystal structure of the title salt, C(10)H(16)N(+)·ClO(4) (-), the 4-butyl-anilinium cation is mirror symmetric, the butyl C atoms and anilinium N atom and 1,4-position C atoms of the benzene ring being located on the mirror plane; the perchlorate anion is also mirror symmetric, with two O atoms and one Cl atom lying on the mirror plane. Trifurcated N-H⋯O hydrogen bonding is observed between the cation and anion in the crystal structure.

Isonicotinonitrile-4-methyl-benzoic acid (1/1).

The title structure, C(6)H(4)N(2)·C(8)H(8)O(2), is built up from an assembly of isonicotinonitrile and 4-methyl-benzoic acid mol-ecules and may be regarded as a co-crystal. The two planar mol-ecules [r.m.

5-(1H-Tetra-zol-5-yl)-1H-indole monohydrate.

In the title compound, C(9)H(7)N(5)·H(2)O, the inter-planar angles between the benzene and tetra-zole rings and between the benzene and imidazole rings are 8.71 (3) and 1.32 (2)°, respectively.

[Three-dimensional finite element analysis of effect of root canal taper and post on tooth stress distribution].

Objective: To evaluate the effect of root canal taper and post on tooth stress distribution.

Methods: Three-dimensional finite element models of human mandibular first molar with root canals prepared with 35# K file, ProTaper and Profile were established. The tooth were restored with fiber-resin, stainless steel and silver amalgam posts respectively.

Dichloridobis(3,5-dimethyl-1H-pyrazol-4-amine-κN)cobalt(II).

In the title compound, [CoCl(2)(C(5)H(9)N(3))(2)], the Co(II) atom adopts a slightly distorted tetra-hedral coordination geometry provided by two chloride anions and two N atoms from the organic ligands. The dihedral angle between the pyrazole rings is 85.91 (10)°.

[Clinical study of repair the defect of immediate implant by acellular dermal matrix].

Objective: To evaluate the clinical effect of acellular dermal matrix allograft in repairing the oral mucosal defect of immediate implant.

Methods: 51 cases underwent immediate implant surgery for 67 implants right after the teeth or roots extracted. The mucosal defect of implant areas were repaired by acellular dermal matrix.
