The possible \(B\pi \) molecular state and its radiative decay

Recently, several exotic bosons have been confirmed as multi-quark states. However, there are violent disputes about their inner structures, namely if they are molecular states or tetraquarks, or even mixtures of the two structures. It would be interesting to search experimentally for non-strange four-quark states with open charm or bottom which are lighter than \(\Lambda _c\) or ...

The new interaction suggested by the anomalous \(^8\) Be transition sets a rigorous constraint on the mass range of dark matter

The WIMPs are considered to belong to the favorable dark matter (DM) candidates, but the upper bounds on the interactions between DM and standard model (SM) particles obtained by the upgraded facilities of DM direct detection get lower and lower. Researchers turn their attention to the search for less massive DM candidates, i.e. light dark matter of the MeV scale. The recently ...

Efficient acquisition of iron confers greater tolerance to saline-alkaline stress in rice (Oryza sativa L.)

To elucidate the mechanisms underlying tolerance to saline-alkaline stress in two rice genotypes, Dongdao-4 and Jigeng-88, we exposed them to medium supplemented with 10 mM Na2CO3 and 40 mM NaCl (pH 8.5). Dongdao-4 plants displayed higher biomass, chlorophyll content, and photosynthetic rates, and a larger root system than Jigeng-88 under saline-alkaline conditions. Dongdao-4 had a ...

Increased activity of the complement system in cerebrospinal fluid of the patients with Non-HIV Cryptococcal meningitis

Backgrounds Cryptococcal meningitis (CM) has been known to lead to significant morbidity and mortality. The relative contribution of the complement system in protection and pathogenesis during CM remains largely unknown. The purpose of this study was to evaluate the baseline complement component profiles in human cerebrospinal fluid (CSF) and plasma from non-HIV patients with CM, ...

Exploring open-charm decay mode \(\Lambda _c\bar{\Lambda }_c\) of charmonium-like state Y(4630)

The newly observed X, Y, Z exotic states are definitely not in the standard \(Q\bar{Q}'\) structures, thus their existence composes a challenge to our understanding on the fundamental principles of hadron physics. Therefore the studies on their decay patterns which are determined by the non-perturbative QCD will definitely shed light on the concerned physics. Generally the ...

Rab14 Act as Oncogene and Induce Proliferation of Gastric Cancer Cells via AKT Signaling Pathway

Rab14 is a member of RAS oncogene family, and its dysfunction has been reported to be involved in various types of human cancer. However, its expression and function were still unclear in gastric cancer. The aim of this study was to investigate the function and mechanism of Rab14 in gastric cancer cell lines. Quantitative real-time PCR (qRT-PCR) was performed in 17 gastric ...

Efficient method for transfer of microinjected eggs to mouse ampulla for generating transgenic mice

Background The new method described here is highly efficient in transferring microinjected mouse eggs (MEs) through the bursa membrane of a surrogate mother mouse to the ampulla of the oviduct without damaging the blood vessels on the bursa membrane. Results This method causes no loss of blood, and it produces newborn pups/founders from approximately 70% of the transferred MEs, ...

Burkholderia pseudomallei-derived miR-3473 enhances NF-κB via targeting TRAF3 and is associated with different inflammatory responses compared to Burkholderia thailandensis in murine macrophages

Background Burkholderia pseudomallei (Bp) is the causative agent of melioidosis, a kind of tropical disease. Burkholderia thailandensis (Bt), with a high sequence similarity to Bp, is thought to be an avirulent organism. Since there are numerous similarities between Bp and Bt, their differences in pathogenesis of host response and related mechanism are still undermined. In recent ...

Down-Regulation of CXCL12/CXCR4 Expression Alleviates Ischemia-Reperfusion-Induced Inflammatory Pain via Inhibiting Glial TLR4 Activation in the Spinal Cord

Toll-like receptor 4 (TLR4) is important for the pathogenesis of inflammatory reactions and the promotion of pain processing after ischemia/reperfusion (IR) in spinal cord. Recently, C-X-C chemokine ligand 12 (CXCL12) and its receptor, C-X-C chemokine receptor 4 (CXCR4), were demonstrated to be simultaneously critical for inflammatory reactions, thereby facilitating glial ...

Intestinal perforation during chemotherapeutic treatment of intra-abdominal desmoid tumor in patients with Gardner’s syndrome: report of two cases

Background A minority of intra-abdominal desmoid tumors is associated with Gardner’s syndrome in which desmoid tumors become an important cause of morbidity and mortality if they are surgically unresectable. Case presentation Here, we report two cases of intestinal perforation during chemotherapy in patients with Gardner’s syndrome-associated intra-abdominal desmoids. One female ...

Serum Metabolomics of Burkitt Lymphoma Mouse Models

Burkitt lymphoma (BL) is a rare and highly aggressive type of non-Hodgkin lymphoma. The mortality rate of BL patients is very high due to the rapid growth rate and frequent systemic spread of the disease. A better understanding of the pathogenesis, more sensitive diagnostic tools and effective treatment methods for BL are essential. Metabolomics, an important aspect of systems ...

Predictive factors for cosmetic surgery: a hospital-based investigation

Background Cosmetic surgery is becoming increasingly popular in China. However, reports on the predictive factors for cosmetic surgery in Chinese individuals are scarce in the literature. Methods We retrospectively analyzed 4550 cosmetic surgeries performed from January 2010 to December 2014 at a single center in China. Data collection included patient demographics and type of ...

Some results on a certain type of difference equation originated from difference Painlevé I equation

In this paper, by using Nevanlinna value distribution theory, we consider a certain type of difference equation, which originates with the difference Painlevé I equation, f ( z + 1 ) + f ( z − 1 ) = A ( z ) f ( z ) + C ( z ) , where A ( z ) , C ( z ) are small meromorphic functions relative to f ( z ) , and we obtain the existence and the forms of rational solutions. We also ...

SHP-1 activation inhibits vascular smooth muscle cell proliferation and intimal hyperplasia in a rodent model of insulin resistance and diabetes

Aims/hypothesis Accelerated migration and proliferation of vascular smooth muscle cells (VSMCs) enhances arterial restenosis after angioplasty in insulin resistance and diabetes. Elevation of Src homology 2-containing protein tyrosine phosphatase 1 (SHP-1) induces apoptosis in the microvasculature. However, the role of SHP-1 in intimal hyperplasia and restenosis has not been ...
