Crohn's disease (CD) is a chronic inflammatory bowel disease of unknown origin that can cause significant disability and morbidity with its progression. Due to the unique nature of CD, surgery is often necessary for many patients during their lifetime, and the incidence of postoperative complications is high, which can affect the prognosis of patients. Therefore, it is essential to identify and manage postoperative complications.

Therefore, high temperature is an important external factor affecting sperm function, and the studies on the underlying mechanisms are of great significance for the treatment of male infertility, improvement of in vitro sperm preservation and further elucidation of spermatogenesis and sperm maturation. It is known currently that the influence of high temperature on sperm involves genetic material, morphology, survival rate, motility and fertility, most of which have been found in various species and may be attributed to the conserved common process or common substances in spermatogenesis and maturation.

Increasing evidence demonstrated that tau pathology played an important role in AD progression. Resveratrol (RSV) has previously proved to exert neuroprotective effect against AD by inhibiting Aβ generation and Aβ-induced neurocytotoxicity, while its effect on tau pathology is still unknown.

Lewy pathology mainly consists of abnormal aggregates of α-synuclein, which play a pivotal role in PD pathophysiology. However, the complexity of PD leads to clinical challenges, and there are still no treatments to halt or slow the neurodegenerative process.

Objective To evaluate the diagnostic accuracy of different laboratory approaches for tuberculous peritonitis(TP).Methods The clinical data of patients with suspected TP who were mainly manifested as ascites in Peking Union Medical College Hospital from January 2014 to June 2017 were retrospectively analyzed. Ascites samples were tested with different diagnostic approaches,including acid fast stain,culture for mycobacterium,real-time polymerase chain reaction for identifying DNA of mycobacterium tuberculosis,and T-cell spot of tuberculosis test(T-SPOT.

To identify variations potentially responsible for prolificacy, we sequenced the genomes of the highly prolific Taihu pig breed and four control breeds. Genes involved in embryogenesis and morphogenesis were targeted in the Taihu pig, consistent with the morphological differences observed between the Taihu pig and others during pregnancy.

NASA recently redefined this syndrome as Spaceflight-Associated Neuro-ocular Syndrome (SANS). Evidence thus reviewed supports that chronic, mildly elevated intracranial pressure (ICP) in space (as opposed to more variable ICP with posture and activity on Earth) is largely accounted for by loss of hydrostatic pressures and altered hemodynamics in the intracranial circulation and the cerebrospinal fluid system.

Methods: We retrospectively reviewed the clinical records of inpatients with NTM BSI at our institution between January 2008 and January 2015 and recorded clinical parameters including age, gender, underlying disease, clinical manifestation, organs involved with NTM disease, species of NTM, laboratory data, treatment and outcome of these patients.
It has been shown that the minimum gravity exposure requirements vary greatly among different physiological systems. A preliminary comparison between two extremes, vessels vs. bones, shows that not only the mechanostat at the tissue level differs greatly, but also the bone loss during weightlessness may also involve calcium deposition-resorption changes.

Intestinal TB (ITB) constitutes a major public health problem in developing countries and has been associated with significant morbidity and mortality. The aim of this study was to characterize the clinical, radiological, endoscopic, and pathological features of ITB and to define the strategy for establishing the diagnosis.

Laying performance is an important economical trait of goose production. As laying performance is of low heritability, it is of significance to develop a marker-assisted selection (MAS) strategy for this trait. Definition of sequence variation related to the target trait is a prerequisite of quantitating MAS, but little is presently known about the goose genome, which greatly hinders the identification of genetic markers for the laying traits of geese.

Methods: The main factors with different levels for development of seed embryonic and seedlings of Pulsatilla cernua were investigated through repeated experiments with multifactorial and cross.
Results: The method for development of seedlings and seeds germination of Pulsatilla cernua were to soak the seeds in the mixed solutions with 2.
Background: To elucidate further from the biomechanical aspect whether microgravity-induced cerebral vascular mal-adaptation might be a contributing factor to postflight orthostatic intolerance and the underlying mechanism accounting for the potential effectiveness of intermittent artificial gravity (IAG) in preventing this adverse effect.
Methodology/principal Findings: Middle cerebral arteries (MCAs) were isolated from 28-day SUS (tail-suspended, head-down tilt rats to simulate microgravity effect), S+D (SUS plus 1-h/d -Gx gravitation by normal standing to simulate IAG), and CON (control) rats. Vascular myogenic reactivity and circumferential stress-strain and axial force-pressure relationships and overall stiffness were examined using pressure arteriography and calculated.
Histone H2B monoubiquitination (H2Bub) is being recognized as a regulatory mechanism that controls a range of cellular processes in plants, but the molecular mechanisms of H2Bub that are involved in responses to biotic stress are largely unknown. In this study, we used wild-type and H2Bub loss-of-function mutations of Arabidopsis (Arabidopsis thaliana) to elucidate which of its mechanisms are involved in the regulation of the plant's defense response to Verticillium dahliae (Vd) toxins. We demonstrate that the depolymerization of the cortical microtubules (MTs) was different in the wild type and the mutants in the response to Vd toxins.

Visual impairment intracranial pressure syndrome (VIIP) is considered a major risk for future human spaceflight. Loss of hydrostatic pressure gradients in vascular and cerebrospinal fluid systems due to the removal of gravity associated with subsequent intracranial and intraocular fluid shifts and the resulting intraocular/intracranial pressure mismatch might be important etiology factors causingVIIP syndrome. Acclimation changes in the ocular and cerebral circulation and the two fluid systems during chronic microgravity exposure and their underlying mechanisms need further elucidation.

Evidence from recent ground and spaceflight studies with animals and humans supports the notion that microgravity-induced vascular remodeling contributes to postflight orthostatic intolerance. In the vascular beds of lower body, such as in splanchnic and lower limb circulation, resistance vessels would undergo hypotrophy and decrement in myogenic tone and vasoreactivity. Thus, despite the concurrent sympathetic activation, the increase in peripheral vascular resistance would still be compromised while astronauts were re-exposed to Earth's 1-G gravity, since ~75 % of the total vascular conductance lies below the heart.
