Phylogeography of lethal male fighting in a social spider mite.

When males fight for access to females, such conflict rarely escalates into lethal fight because the risks and costs involved, that is, severe injury or death, are too high. The social spider mite, does exhibit lethal male fights, and this male-male aggressiveness varies among populations. To understand the evolution of lethal fighting, we investigated aggressiveness in 42 populations and phylogenetic relationships in 47 populations along the Japanese archipelago.

Discussion on the risk factors of developing cardiovascular diseases (CVD) after the kidney transplantation.

To discuss the risk factors of developing cardiovascular disease (CVD) after the kidney transplantation. Retrospective analysis on the data of 1106 patients who had been underwent kidney allotransplantation in People's Hospital of Zhengzhou from July, 2010 to Dec, 2014 and conformed to the inclusion criteria was taken. Cox proportional hazard model was used to analyze the risk factors of developing CVD after the kidney transplantation.

Variation in nesting behavior of eight species of spider mites, Stigmaeopsis having sociality.

Nesting behavior is considered to be an important element of social living in animals. The spider mites belonging to the genus Stigmaeopsis spend their lives within nests produced from silk threads. Several of these species show cooperative sociality, while the others are subsocial.

Clinical effect of treating renal transplant recipients with percutaneous coronary intervention and its safety.

Objective: To explore clinical effect of treating acute coronary syndrome (ACS) of renal transplant recipients with percutaneous coronary intervention and its safety.

Methods: Forty two renal transplant recipients who were diagnosed with acute coronary syndrome and received percutaneous coronary intervention (PCI) in our hospital were selected. Serum creatinine (Cr) and glomerular filtration rate (GFR) were compared before surgery, 48 ~ 72 hour after surgery and one year after surgery.

Significantly increased visceral adiposity index in prehypertension.

Background: The prevalence of prehypertension has increased in China, and prehypertension frequently progress to hypertension over a short time period; both have become public health problems. Therefore, this study was conducted to determine the relationship between the Visceral Adiposity Index (VAI) and blood pressure (BP) in China.

Methods: A cross-sectional epidemiological survey was conducted in China using a stratified random cluster sampling method.

Reproductive isolation between Stigmaeopsis celarius and its sibling species sympatrically inhabiting bamboo (Pleioblastus spp.) plants.

Stigmaeopsis celarius Banks (hereafter Sc) is a spider mite living and feeding on the leaves of various bamboo species such as Moso bamboo [Phyllostachys edulis (=P. pubescens)] and Pleioblastus spp. (Poaceae).

Female performance towards offspring under starved conditions in four phytoseiid species (Acari, Phytoseiidae).

There is an important difference between cannibalism between unrelated individuals and between a mother and its offspring, because the former can be defined as a form of intraspecific competition, but the latter affects the inclusive fitness of individuals. Many examples of cannibalism have been reported in predacious phytoseiid mites. Furthermore, sib cannibalism avoidance is known in several species.

[Clinical study of pulmonary infection in kidney transplantation recipients taking new immunosuppressant].

Objective: To explore the etiopathogenesis, therapy and incidence of pulmonary infection in kidney transplantation recipients taking new immunosuppressant.

Methods: The clinical data from 752 kidney transplant recipients were retrospectively analyzed, who were divided into 3 groups according to the immunosuppressants administered, namely group A (CsA+MMF+Pred, n=226), group B (FK506+MMF+Pred, n=386) and group C (FK506+Rap+Pred, n=140). The incidence and mortality of pulmonary infection were recorded and the analysis of etiopathogenesis, diagnosis and therapy of pulmonary infection were carried out in the 3 groups.

Effects of mating rates on oviposition, sex ratio and longevity in a predatory mite Neoseiulus cucumeris (Acari: Phytoseiidae).

Two aspects of mating effects on the fecundity, sex ratio and longevity of Neoseiulus cucumeris (Acari: Phytoseiidae) were examined in laboratory experiments: (1) females mated by one, two or three different males (unmated and 3 days old) at 5-day intervals, and (2) females mated by males with different age/mating status (number of females mated previously by the male). Females allowed to mate with a second or third male at 5-day intervals produced 39 eggs on average, but those mated with a single male produced 28 eggs on average. Matings with additional males 5 or 10 days after the first male increased the duration of the oviposition period of these females by 5-7 days and at the same time reduced the post-oviposition period by about 10 days.

[Application of tacrolimus and cyclosporine A in HBV-carrying renal transplant recipients].

Objective: To compare the long-term effect and safety of tacrolimus (FK506) and cyclosporine (CsA) in kidney transplant (KT) recipients carrying hepatitis B Virus(HBV).

Methods: A total of 109 patients with HBV were randomized into FK506 group (52 cases) and CsA group (57 cases) after KT, and a 2-year-long follow-up of the patients was conducted to record the patient and graft survival, incidence of acute graft rejection and postoperative liver function.

Results: The 2-year patient/graft survival was 86.

[On the causes of mite pest outbreaks in mono- and poly-cultured moso bamboo forests].

In this paper, the damage of phytophagous mites Schizotetranychus nanjingensis Ma & Yuan, Aponychus corpuzae Rimando and Aculus bambusae Kuang to moso bamboo (Phyllostaychs pubescens) was examined for ten pairs of mono- and poly-cultured forests at six locations in Fujian, China. The results showed that the mite damage in mono-cultured forests (35%) was twice as high as that in poly-cultured forests (17.5% < the injury level of 20%), and the difference was significant by t-test.

Ambulatory migration in mites (Acari: Tetranychidae, Phytoseiidae) to new leaves of moso bamboo shoots.

The migratory behaviour of two tetranychid pest species, Aponychus corpuzae and Schizotetranychus nanjingensis, and one phytoseiid, Typhlodromus bambusae, was studied in several monocultural bamboo forests in Fujian Province, China. The aim of the study was to assess how the ambulatory immigration of tetranychid and phytoseiid mites from the ground to new leaves is affected by a sticky barrier around the stem, by the age of bamboo shoots or by shoot density. The results show that while the sticky barrier is particularly effective at disrupting the ambulatory immigration from the ground to new leaves of S.
