The aim of the present study was to investigate the effects of mechanical stress on the osteogenic differentiation of human ligamentum flavum cells via the bone morphogenetic protein (BMP)‑Smad1 signaling pathway. Mechanical stress increased cell proliferation and induced osteogenic differentiation of human cells derived from the ossification of the ligamentum flavum (OLF). In addition, mechanical stress activated osteocalcin (OC), alkaline phosphatase (ALP) and runt‑related transcription factor 2 (RUNX‑2) mRNA expression, and suppressed Ets proto‑oncogene 1 (Ets‑1) and sex determining region Y‑box 2 (SOX‑2) mRNA expression in OLF cells...

Fruit flies in the genus Bactrocera are global, economically important pests of agricultural food crops. However, basic life history information about these pests, which is vital for designing more effective control methods, is currently lacking. Artificial diets can be used as a suitable replacement for natural host plants for rearing fruit flies under laboratory conditions, and this study reports on the two-sex life-table parameters of four Bactrocera species (Bactrocera correcta, Bactrocera dorsalis, Bactrocera cucurbitae, and Bactrocera tau) reared on a semi-artificial diet comprising corn flour, banana, sodium benzoate, yeast, sucrose, winding paper, hydrochloric acid and water...

BACKGROUND: Oxidation of LDL particles entrapped in the extracellular matrix of the arterial wall is a key factor in the development of atherosclerosis. Lipid oxidation products, such as malondialdehyde (MDA), react with surrounding extracellular matrix proteins and cause modifications that are recognized by the immune system. MDA modification of collagen type IV is increased in carotid lesions from symptomatic patients and correlates with autoantibodies against MDA-modified collagen type IV in plasma...

OBJECTIVE: Preliminary evidence suggests that serotonin reuptake inhibitor (SRI) use may increase postictal respiratory drive and prevent death. We sought to determine whether SRIs are associated with improved all-cause and possible seizure-specific mortality in patients with epilepsy. METHODS: Patients with epilepsy and a random 10:1 sample without epilepsy were extracted from The ClinicAl research using LInked Bespoke studies and Electronic health Records (CALIBER) resource...

BACKGROUND AND AIMS: Anaemia affects up to 74% patients with Crohn's disease (CD) and ulcerative colitis (UC) and is correlated with decreased quality of life. The European Crohn's and Colitis Organisation (ECCO) recommends at least annual screening for iron-deficiency anaemia. We aimed to determine the prevalence of anaemia, frequency of anaemia screening and factors associated with anaemia in a retrospective study of mild to moderate inflammatory bowel disease (IBD) in the USA. METHODS: Adults with at least two outpatient encounters for IBD between 2010 through 2014 who contributed laboratory information were identified from MarketScan, a US commercial claims database...

OBJECTIVE: Pediatric patients often require larger doses of antiepileptic drug (AED) than adults in order to attain therapeutic serum concentrations and/or achieve seizure control. Safety and efficacy data are often extrapolated from adult literature; hence, optimal dosage may only be determined anecdotally or based on expert opinion. With limited pediatric dosing guidelines, milligrams per day that are based on weight may exceed the maximum adult dose. The primary objective of this study is to evaluate the safety of exceeding maximum doses as specified by the US Food and Drug Administration or manufacturers of commonly used AEDs in pediatric patients...

Systemic lupus erythematosus (SLE) is a typical autoimmune disorder with multiple organ involvement and unknown etiology. It has been shown that polymorphic variants of the genes encoding key enzymes of folate and methionine metabolism may influence DNA methylation. Genomic DNA was extracted from blood samples of 150 SLE patients and 160 controls, matching age, sex, and ethnicity. MTHFR rs1801133C>T and MTR rs1805087A>G polymorphisms were genotyped by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method...

INTRODUCTION: There are few longitudinal studies of dementia in developing countries. We used longitudinal data from the Maracaibo Aging Study to accurately determine the age- and sex-specific incidence of dementia in elderly Latin Americans. METHODS: The Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition, Text Revision) was used to diagnose dementia, which was classified as Alzheimer's disease, vascular dementia, or other. Age- and sex-specific incidence was estimated as the number of new cases of dementia divided by person-years (p-y) of follow-up...

BACKGROUND: Adults with congenital heart disease (ACHD) are affected by atrial arrhythmias (AA). To elucidate the impact of AA on prognosis, we aimed to determine the impact of AA on death, heart failure and stroke in ACHD patients in a prospective nationwide clinical registry. METHODS: All patients aged ≥18years included in the CONCOR registry per October 1st 2015 were analysed. Prior AA was defined as atrial fibrillation, atrial flutter or unspecified AA before inclusion in CONCOR and new-onset AA as a first documented AA during follow-up...

Within populations of the amphipod crustaceans Orchestia gammarellus and Orchestia aestuarensis, a proportion of females produce thelygenic (female-only) broods, which often contain intersexual individuals. This phenomenon is associated with the presence of two putative feminizing parasites, the paramyxid Paramarteilia orchestiae and the microsporidian Dictyocoela cavimanum, which frequently co-infect the same host. In order to determine which of the parasites causes feminization, Orchestia were resampled from the type locality of P...

BACKGROUND: Reported cut-offs for childhood TSH and FT4 reference ranges vary widely and the knowledge on the determinants of childhood thyroid function is sparse. We aimed to summarize the existing studies on thyroid function reference ranges in children. Furthermore, our objective was to investigate the determinants of childhood TSH and FT4 concentration in a population based-prospective cohort. METHODS: First, to identify studies on childhood thyroid reference ranges, we systematically searched The National Library of Medicine's PubMed, Embase, Ovid Medline, Web of Science and Google Scholar databases...

BACKGROUND: Surgical site infections (SSIs) result in delayed wound healing, increased use of antibiotics and increased length of hospital stay, putting remarkable physical and financial burden on patients, their relatives and the healthcare facilities. Patient-related factors, such as pre-existing colonization with antibiotic-resistant bacteria, and clinical-related factors, such as adherence to sterile techniques, contribute to the development of SSIs. The objective of this study, therefore, was to determine the SSI rate and risk factors for emergency abdominal surgeries at Tamale Teaching Hospital, Ghana...

Sex affects the risk, treatment responses and outcome of many types of cancers. The mechanism of gender disparity in development of hepatocellular carcinoma (HCC) remains obscure. Sex-determining region on Y chromosome (SRY) was overexpressed in approximate 84% male patient HCC. Moreover, we are the first to generate a liver-specific transgenic (TG) murine model with overexpression of the male specific gene SRY. Subject to a single intraperitoneal injection N-nitrosodiethylamine (DEN) at day 14, TG and wildtype (WT) mice of both genders were sacrificed at different time points (6-13...

Sex differences in patterns of methamphetamine (MA) abuse have been reported with females (humans and rodents) showing an elevated addiction phenotype. Previous findings indicate MA-induced hypothalamic-pituitary-adrenal (HPA) axis activation is also sexually dimorphic with females exhibiting an elevated glucocorticoid release and differential neural activation patterns within HPA axis-associated brain regions. These effects may contribute to sex differences in abuse. To determine the role of gonadal hormones in mediating sex differences in MA-induced glucocorticoids, male and female C57BL/6J mice were gonadectomized or sham-operated, and following recovery, injected with MA (5 mg/kg) and sacrificed 60 minutes or 120 minutes later...

BACKGROUND: Low blood 25-hydroxyvitamin D (25(OH)D) concentrations have been associated with cancer in dogs. Little research has examined what other factors may affect 25(OH)D concentrations. OBJECTIVES: (1) To determine whether the presence of cancer (lymphoma, osteosarcoma, or mast cell tumor [MCT]) in dogs is associated with plasma 25(OH)D concentrations and (2) identify other factors related to plasma 25(OH)D concentrations in dogs. ANIMALS: Dogs newly diagnosed with osteosarcoma (n = 21), lymphoma (n = 27), and MCT (n = 21) presented to a tertiary referral oncology center, and healthy, client-owned dogs (n = 23)...
