[Selective Adsorption of Au(Ⅲ) by Activated Carbon Supported Polythioamides and Adsorption Mechanism].

By using in-situ synthesis of polythioamide (PTA) on activated carbon (AC), a polythioamide-modified activated carbon-based adsorbent (AC-PTA) was successfully prepared and used to study the selective adsorption effect and mechanism of Au(Ⅲ) in wastewater. The results showed that AC-PTA exhibited excellent selective adsorption to Au(Ⅲ) in the coexisting solution of multiple metal ions in a wide pH range (<5.0).

Pathological significance of urinary complement activation in diabetic nephropathy: A full view from the development of the disease.

Aims/introduction: The aim of the present study was to obtain a full view of the changes of urinary complement activation products in the development of diabetic nephropathy and explore their possible significance in the disease process.

Materials And Methods: A total of 62 patients at different stages of diabetic nephropathy, 20 diabetes patients without nephropathy and 20 healthy persons were enrolled. Urinary complement activation products, including C3a, C5a and C5b-9, were measured, and their associations with the progression of the disease were analyzed.

Lectin-induced renal local complement activation is involved in tubular interstitial injury in diabetic nephropathy.

Background: Complement has been suggested to be involved in diabetic nephropathy (DN), but the exact significance and underlying mechanisms remain unclear. Data about renal local complement activation in DN patients is scarce. The purpose of the study was to clarify the significance and mechanism of renal local complement activation in DN.

A Devonian tetrapod-like fish reveals substantial parallelism in stem tetrapod evolution.

The fossils assigned to the tetrapod stem group document the evolution of terrestrial vertebrates from lobe-finned fishes. During the past 18 years the phylogenetic structure of this stem group has remained remarkably stable, even when accommodating new discoveries such as the earliest known stem tetrapod Tungsenia and the elpistostegid (fish-tetrapod intermediate) Tiktaalik. Here we present a large lobe-finned fish from the Late Devonian period of China that disrupts this stability.

[Changes of pathologic feature and microtubulin associated protein 2 in nervous system of hens with organophosphate-induced delayed neuropathy induced by 2,4,6-trimethylbenzoyl phenylphosphonate].

Objective: To develop the organophosphate-induced delayed neuropathy (OPIDN) hen model with 2,4,6-trimethylbenzoyl phenylphosphonate (TOCP), and observe the change of pathology and investigate the alterations of microtubulin associated protein 2 (MAP2).

Methods: 48 adult hens were randomly divided into four groups, including three experimental groups and control group (n = 12 each group). The hens in three experimental groups were treated with TOCP by gavage at single dosages of 250, 500 and 750 mg/kg respectively while the control hens received an equivalent volume of corn oil by gavage.

[Clinical characteristics, diagnosis and treatment of hepatoid adenocarcinoma of the stomach].

Objective: To investigate the clinical characteristics,diagnosis and treatment of hepatoid adenocarcinoma of the stomach.

Methods: Clinical data of 13 hepatoid adenocarcinomas of the stomach, collected from 201 cases of gastric cancer, were analyzed retrospectively.

Results: Of the 201 gastric carcinomas, there were 13 AFP-producing adenocarcinomas of the stomach, the positive rate was 6.

[Effect of HuperzineA on neurophathologic change of mouse exposed by isocarbophos and phoxim].

Objective: In order to assessment the Huperzine A (HupA) on CNS of mice exposed by phoxim and isocarbophos.

Methods: One group was given tween-80 or peanut oil as control. One group was given phoxim or isocarbophos alone as phoxim or isocarbophos group.
