Reclamation is essential for restoring the ecological function of soil in mining areas. However, the microbiological mechanism of soil ecological function reconstruction under different reclamation measures still needs to be clarified. Clarifying the characteristics of soil bacterial and fungal communities, assembly mechanisms, and their relationship with physicochemical properties under different reclamation measures is crucial for reshaping the ecological stability of soil in mining areas.

Understanding the decomposition dynamics and driving factors of manure in the soil subjected to different reclaimed years could provide theoretical basis to rational utilization of manure and soil fertility improvement in coal mining area. Cattle manure and pig manure were mixed with soils subjected to different reclaimed years (one year, R; 10 years, R; and 30 years, R) at the ratio of manure carbon to soil mass of 4 to 100, so as to examine manure decomposition characteristics using the nylon mesh bag (15 cm deep of soil buried) in the Shanxi coal mine reclamation area, with no manure addition as control (CK). Soil samples were collected at day 12, 23, 55, 218, 281, and 365 to measure the contents of soil manure residual, soil microbial biomass carbon (MBC), and dissolved organic carbon (DOC).

Article Synopsis
  • Acute myocardial infarction (AMI) is a significant health issue worldwide, and this study explored the effects of Angiotensin IV (Ang IV) on AMI in mice, revealing its potential protective properties.
  • The infusion of Ang IV prior to AMI significantly lowered mortality rates, reduced inflammation, decreased cardiomyocyte apoptosis, and improved heart function compared to untreated AMI subjects.
  • The research indicated that Ang IV may help mitigate oxidative stress, inflammation, and fibrosis in the heart, suggesting a therapeutic role for Ang IV in the aftermath of an AMI.

Article Synopsis
  • Dynesys is a dynamic stabilization system designed to reduce issues related to spinal fusion surgeries, but its advantages over traditional fusion are not definitively proven.
  • Current clinical reports indicate that short-term outcomes of Dynesys are comparable to those of lumbar fusion, while medium-term studies show more positive results for Dynesys.
  • However, long-term studies have not been as promising, making it unclear whether Dynesys is better than fusion for treating lumbar degenerative conditions.

Visceral leishmaniasis (VL) caused by Leishmania spp. is an important vector-borne disease prevalent in China. VL was rampant in the vast area of China north of the Yangtze River before the founding of the People's Republic of China in 1949.

As a zoonotic parasitosis caused by the parasitism of Echinococcus larvae, echinococcosis imposes serious disease and economic burdens on human beings and society, and is thus a global public health issue. Its complex life history, wide distribution, the combined influence of various epidemic factors, coupled with the unique natural environment, customs, and religious beliefs in endemic areas, pose a huge challenge to the national echinococcosis control programme in China. Accurate early detection and confirmation of diagnosis of echinococcosis, the use of effective drugs, real-time surveillance of the infection status of populations and various hosts, controlling the source of infection, and blocking the route of transmission are of enormous significance for control.

Very poor reclaimed soil quality and weak microbial activity occur in the reclamation area of a coal gangue landfill in the Loess Hills. The fourth and fifth years after farmland soil was reclaimed were studied, and the changes in and carbon source utilization characteristics of rhizosphere (R) and non-rhizosphere (S) soil microorganisms under organic and inorganic (OF), inorganic (F), and organic (O) fertilizer application and a control treatment (CK) in soybean (S) and maize (M) rotation systems were compared and analysed in Guljiao Tunlan, Shanxi Province, China. Biolog-EcoPlate technology was used to analyse the mechanism of soil characteristic change from the perspective of soil microbial metabolism function to provide a theoretical basis for reclamation and ecological reconstruction in this area.

Background: The larval stages of the tapeworms Echinocoocus granulosus and Echinococcus multilocularis are the causative agents of human cystic echinococcosis (CE) and human alveolar echinococcosis (AE), respectively. Both CE and AE are chronic diseases characterised by long asymptomatic periods of many years. However, early diagnosis of the disease is important if treatment and management of echinococcosis patients are to be successful.

October 2017

Kala-azar was once transmitted in the northern area of the Yangtze River in China, including 16 provinces (cities or autonomous regions). Through the great continuing prevention and control effort, this disease has been effectively controlled in the most of endemic areas. However, because the epidemic factors of the disease are complex, this disease still transmits or sporadically occurs in the western part of China, including 60 counties of Xinjiang, Gansu, Sichuan, Inner Mongolia, Shanxi, and Shaanxi provinces (autonomous regions).

Objective: To clone and express the basement membrane specific heparan sulfate proteoglycan core protein (H3), and to evaluate its effect in detection of human cystic echinococcosis (CE).

Methods: The H3 gene immunoscreened from the cDNA library was cloned into pGEX-4T vector. The recombinant plasmid pGEX-3X-AgB8/3 was transformed into BL21 strains and induced by isopropyl-β-D-thiogalactopyranoside (IPTG).

Objective: To evaluate the reactivity of adult hookworm antigens to serum from patients with hookworm disease, and analyze in the serum class- or subclass-specific antibodies that show superior antigen recognition.

Methods: Sera from healthy participants, patients infected by Necator americanus and those with other parasitic infections were processed for ELISA, which used raw antigens extracted from adult worms of Necator americanus as the coating antigen, and different classes or subclasses of anti-human antibody labeled with HRP as the secondary antibody. The sensitivity and specificity of the assay with various secondary antibodies were compared.

In 2008 and 2009, an outbreak of desert-subtype zoonotic visceral leishmaniasis occurred in Jiashi county, Xinjiang, China. So far, no animal reservoir has been identified for this type of visceral leishmaniasis. Therefore, we surveyed the most common mammals (wild and domestic) for Leishmania infections during the outbreak in 2008 and 2009 in order to identify the source of the visceral leishmaniasis in this region.

Background: Leishmania infantum infections in dogs play a crucial role in the transmission of pathogens causing visceral leishmaniasis to humans in the Gansu province, northwest China. To be able to control zoonotic transmission of the parasite to humans, a non-invasive loop-mediated isothermal amplification (LAMP) assay to specifically detect L. infantum infections in dogs was developed.

Background: Visceral leishmaniasis (VL) is a life-threatening disease caused by protozoan parasites of the Leishmania donovani complex. Early case detection followed by adequate treatment is essential to the control of VL. However, the available diagnostic tests are either invasive and require considerable expertise (parasitological demonstration of the parasite in tissue smears) or unable to distinguish between past and active infection (serological methods).

Human cystic and alveolar echinococcoses are zoonotic diseases caused by the larval stages of Echinococcus granulosus and Echinococcus multilocularis, respectively. As the diseases are co-endemic in many areas of the world, a simple and rapid test for the differential diagnosis of cystic echinococcosis (CE) and alveolar echinocoocosis (AE) is needed. Here, we describe the development of an immunochromatographic test (ICT) using crude hydatid cyst fluid and a recombinant 18-kDa protein (rEm18) as antigens for the detection of E.
