Child growth stunting is common in low-income countries, possibly due to insufficient protein intakes. Most previous studies have concluded that children's protein intakes are adequate in relation to estimated requirements, but these studies did not consider issues of protein digestibility and effects of infection on dietary protein utilization. Using an alternative approach to assess the possible role of protein inadequacy in children's growth restriction, the results of 18 intervention trials in which supplementary protein or amino acids were provided to children ages 6-35 months and growth outcomes were reviewed...

Hemorrhagic enteritis (HE) is an acute viral disease that affects avian species, particularly turkeys, compromising their commercial production and having a negative effect on animal welfare. Turkey adenovirus 3 (TAdV-3), is the main causal agent of the disease. In this study, we considered 3 groups of turkeys to achieve 2 purposes: 1) A preliminary investigation on the microbiota content in the 4 parts of healthy turkey's intestine (group A), namely duodenum, jejunum, ileum, and ceca was done; 2) an investigation on the relationship between natural infections with TAdV-3 and the intestinal microbiota in the jejunum, where HE mostly develops, comparing group A with animals with molecular positivity for the virus and with clinical signs of HE (group B) and animals with molecular positivity for the virus but without clinical signs (group C)...

Several studies have reported that hepatitis B virus (HBV) infection may decrease the risk of stroke. However, its association is controversial. Thus, we conducted a systematic review and meta-analysis to investigate the relationship between hepatitis B virus (HBV) infection and the risk of stroke. Relevant studies published before May 2017 were identified by searching PubMed, EMBASE, and ISI Web of Science. The relationships between HBV infection and the risk of stroke were assessed using odds ratio (OR)/risk ratio (RR) values and the corresponding 95% confidence intervals (CIs)...

CCCH type zinc finger antiviral protein (ZAP) is a host restriction factor that inhibits the replication of a variety of viruses in mammals. However, little is known about its antiviral activity on avian tumor virus. Avian leukosis virus subgroup J (ALV-J), an oncogenic retrovirus, induces myelocytomas and various other tumors in meat and egg type chickens. Here, we identified a chicken ZAP (chZAP) that increased at early stage, and subsequently decreased after infection of ALV-J in DF-1 cells, indicating the inducible feature of the endogenous chZAP...

Endoplasmic reticulum (ER)-stress-mediated apoptosis is a host defense mechanism against Mycobacterium tuberculosis (Mtb) infection. Calreticulin (CRT) is the major calcium-binding chaperone protein. Previous reports have suggested a close relationship between the cell-surface expression of CRT and apoptosis. In this study, the role of CRT during Mtb infection was examined. The results showed that Mtb infection induces CRT production by macrophages and that CRT levels are correlated with the degree of apoptotic cell death...

Orf virus has been utilized as a safe and efficient viral vector against not only diverse infectious diseases, but also against tumors. However, the nature of the genes triggered by the vector in human cells is poorly characterized. Using RNA sequencing technology, we compared specific changes in the transcriptomic profiles in human foreskin fibroblast cells following infection by the orf virus. The results indicated that orf virus upregulates or downregulates expression of a variety of genes, including genes involved in antiviral immune response, apoptosis, cell cycle and a series of signaling pathways, such as the IFN and p53-signaling pathways...

Despite many advances in conventional treatment strategies, there is no effective treatment modality for malignant gliomas. Gene therapy may offer a promising option for gliomas and several gene therapy approaches have shown anti-tumor efficiency in previous studies. Mesenchymal stem cell-based gene therapies, in which stem cells are genetically engineered to express therapeutic molecules, have shown tremendous potential because of their innate homing ability. In this study, human menstrual blood-derived MSCs (MenSC), a novel type of multipotential MSCs displays tropism for human malignant glioma when used as a gene delivery vehicle for therapeutics...

As an increasingly common cause of skin infections worldwide, the prevalence of antibiotic-resistant Staphylococcus aureus (S. aureus) across China has not been well documented. This literature aims to study the resistance profile to commonly used antibiotics, including macrolides, fusidic acid (FA) and mupirocin, and its relationship to the genetic typing in 34 S. aureus strains, including 6 methicillin-resistant S. aureus (MRSA), isolated from a Chinese hospital. The MIC results showed 27 (79.4%), 1 (2.9%) and 6 (17...

Prophylactic and/or therapeutic vaccines have an important potential to control Trypanosoma cruzi (T. cruzi)infection. The involvement of regulatory/suppressor immune cells after an immunization treatment and T. cruzi infection has never been addressed. Here we show that a new trans-sialidase-based immunogen (TSf) was able to confer protection, correlating not only with beneficial changes in effector immune parameters, but also influencing populations of cells related to immune control. Regarding the effector response, mice immunized with TSf showed a TS-specific antibody response, significant delayed-type hypersensitivity (DTH) reactivity and increased production of IFN-γ by CD8+ splenocytes...

Ring fixation is a powerful tool in the treatment of bone defects. The ability to create high-quality, biologically normal new bone of even massive proportions using distraction osteogenesis is a major reason for its success. In addition, ring fixation provides the ability to limit the risk of deep infection, improves flexibility in limb length control and alignment, and increases soft tissue coverage options. The drawbacks of ring fixation include long frame times, pin problems, risk of joint contractures, and difficult usage in areas with a large soft tissue envelope such as the thigh...

Gustilo-Anderson IIIB tibial fractures and infected tibial nonunions represent particular challenges for the orthopaedic trauma surgeon. Debridement of dysvascular bone and soft tissues can create composite bone and soft tissue defects. Restoring the soft tissue envelope is a critical step in preventing or treating ongoing infection and in restoring local blood supply. Shortening and angulation techniques, including the gradual expansion muscle flap, rely on distraction histogenesis to address composite bone and soft tissue loss...

High-energy, open tibial shaft fractures may result in significant comminution, bone loss, and soft tissue injuries. Early, thorough debridement of all nonviable tissue is of critical importance in treating these fractures as an inadequate initial debridement increases the risk of infection and nonunion. Large iatrogenic bone and soft tissue defects can result from debridement and will require subsequent reconstruction by both orthopaedic and plastic surgeons. Although a variety of approaches exist to address these reconstructions, successful management of bone defects remains a considerable challenge...
