This experiment investigated whether retrieval-induced forgetting (RIF) would be found in children's self-generated autobiographical memory recall. An adapted version of the RIF paradigm for adults' autobiographical memories was administered to 8- and 9-year-old children (N = 65). We hypothesized that RIF would be found in terms of both number of memories recalled and amount of memory detail reported. The relationship between memory detail at the retrieval practice phase and RIF magnitude was also investigated...

Advances in reproductive medicine have significantly increased the success of fertility treatments. Nevertheless, some women experience recurrent implantation failure (RIF) after in-vitro fertilization (IVF) or recurrent pregnancy loss (RPL). Imbalances in the immune system and failure to achieve immune tolerance to the foetus have been implicated as potentially modifiable causes of idiopathic RIF and RPL. As such, women are increasingly being treated with immunomodulatory agents in an attempt to achieve a successful pregnancy...

West Nile virus-associated disease is one of the most widespread vector-borne diseases in the world. In Morocco, the first cases were reported in horses in 1996 and the disease re-emerged in 2003 and in 2010. The objective of this work was to study the epidemiological situation of WNV-associated infection in Morocco, by quantifying the seroprevalence of anti-WNV IgM and IgG antibodies in horses in different bioclimatic regions-zones of Morocco in 2011. During the months of May, June and July 2011, 840 serum samples were collected from horses in four regions characterized by different environmental and climatic features such as altitude, temperature and precipitation...

Rifampin (RIF) is a bactericidal antibiotic drug and potent inducer of hepatic and intestinal cytochrome P-450 (CYP-450) enzyme systems. Given by mouth or intravenously, it can cause numerous clinical drug interactions; thus, alternative systems of drug delivery that bypass some or all of its toxic effects are well worth investigating. In this study, a controlled layer-by-layer (LBL) process of encapsulating RIF in biocompatible alginate and chitosan polymers loaded onto Fe3 O4 nanoparticles was developed. Fe3 O4 nanoparticles were synthesized from FeCl3 ·6H2 O using a hydrothermal procedure...

Rapid and accurate drug-susceptibility testing (DST) is essential for the treatment of multi- and extensively drug-resistant tuberculosis (M/XDR-TB). We compared the utility of genotypic DST assays with phenotypic DST (pDST) using BACTEC 960 MGIT or Löwenstein-Jensen to construct M/XDR-TB treatment regimens for a cohort of 25 consecutive M/XDR-TB patients and 15 possible anti-TB drugs.Genotypic DST results from Cepheid GeneXpert MTB/RIF (Xpert) and line probe assays (LPAs: Hain GenoType MTBDRplus 2.0 and MTBDRsl 2...

BACKGROUND: The WHO algorithm for the diagnosis of tuberculosis in seriously ill HIV-infected patients lacks a firm evidence base. We aimed to develop a clinical prediction rule for the diagnosis of tuberculosis and to determine the diagnostic utility of the Xpert MTB/RIF assay in seriously ill HIV-infected patients. METHODS: We conducted a prospective study among HIV-infected inpatients with any cough duration and WHO-defined danger signs. Culture-positive tuberculosis from any site was the reference standard...

Adverse drug reactions are inevitable risk factors associated with use of modern medicines. First-line anti-tuberculosis drugs contribute to diverse pathological complications, and hepatotoxicity is one of them. This study investigated the effects of anti-TB drugs in combination (rifampicin [RIF] + isoniazid [INH] + pyrazinamide [PZA]) on Wistar rats. Rats were grouped as control group (saline), toxicant group that was given (30.85 mg/kg b.wt., INH + 61.7 mg/kg b.wt., RIF + 132.65 mg/kg b.wt. PZA in dosage extrapolated from dose that is used in human)...

Albuminuria is an independent risk factor for renal interstitial fibrosis (RIF). Glomerular-filtered albumin in endocytic and non-endocytic pathways may injure proximal tubular epithelial cells (PTECs) via megalin and TGFβRII, respectively. Since megalin and TGFβRII are both modified by post-translational core fucosylation, which plays a critical role in RIF. Thus, we sought to identify whether core fucosylation is a potential target for reducing albumin-induced injury to PTECs. We constructed a human PTEC-derived cell line (HK-2 cells) and established an in vitro model of bovine serum albumin (BSA) injury...

BACKGROUND: The first-line antituberculosis (anti-TB) drugs, isoniazid (INH), rifampicin (RIF), ethambutol (EMB), and pyrazinamide (PZA), are effective in the treatment of pulmonary tuberculosis. However, the toxicity of these drugs in the clinical setting limits their use. Here, we evaluated the effects of anti-TB drugs on the reproductive system in female rats. METHODS: Thirty-five female Wistar rats were assigned into five groups of seven animals each. The control group received normal saline, whereas others received INH (5 mg/kg), RIF (10 mg/kg), EMB (15 mg/kg), and PZA (15 mg/kg) through gavage thrice a week for 8 consecutive weeks...

Drug Resistant Tuberculosis (DRTB) is an emerging problem world-wide. In order to control the disease and decrease the number of cases overtime a prompt diagnosis followed by an appropriate treatment should be provided to patients. Phenotypic DST based on liquid automated culture has greatly reduced the time needed to generate reliable data but has the drawback to be expensive and prone to contamination in the absence of appropriate infrastructures. In the past 10 years molecular biology tools have been developed...

We describe a 44-year-old female with triple-negative breast cancer who developed skin erythaema, sclerosis and contracture of her entire right breast 15 months after completion of post-lumpectomy chemotherapy and radiotherapy, consistent with post-irradiation morphoea (PIM). PIM is a rare complication of breast irradiation that impairs a patient's quality of life. PIM is located usually at the radiation port or in the surrounding tissue. Clinically, PIM is misdiagnosed commonly as lymphoedema and cellulitis in the early inflammatory phase, and recurrent breast cancer, chronic radiodermatitis (CRD), radiation-induced fibrosis (RIF), post-irradiation pseudosclerodermatous panniculitis (PIPP), atypical vascular lesions (AVL) or angiosarcoma (AS) in the late burnout phase...

Mycobacterium tuberculosis (MTB) is the causative agent of pulmonary tuberculosis. Rapid and accurate diagnosis is crucial to tuberculosis control and prevention. A series of diagnostic methods has been available for MTB detection; however, new rapid, simple and affordable methods are needed. In this study, a multiple cross displacement amplification (MCDA)-based assay was developed to detect the IS6110 gene of the M. tuberculosis complex. Hydroxy naphthol blue (HNB), a colorimetric indicator, was used to detect amplification products...

The most common definition of repeated implantation failure (RIF) is the failure to obtain a clinical pregnancy after three completed IVF cycles. This definition, however, may lead to misuse of the diagnosis. To disentangle this, we set up a mathematical model based on the following main assumptions: rate of success of IVF constant and set at 30%; and RIF postulated to be a dichotomous condition (yes or no) with a prevalence of 10%. On this basis, the expected cumulative chance of pregnancy after three and six cycles was 59% and 79%, respectively...

RIF (repeated implantation failure) women with immunologic basis and cellular abnormalities may benefit from intravenous immunoglobulins (IVIG) as an immunomodulator based on different studies. In this study, we evaluated the effect of IVIG on the frequency and function of Th17 and Treg cells, as two important subgroups of CD4(+) T cells in implantation and pregnancy rates. Seventy-two RIF patients with preconception Th1⁄Th2 ratio and natural killer (NK) cells frequency and activity elevation were selected and divided into two groups; 40 out of 72 received IVIG, aspirin, and heparin (anoxaparin) and constituted the treatment group and 32 patients received aspirin and heparin (anoxaparin) and no IVIG and were the control group...

Renal interstitial fibrosis (RIF) is a common outcome in various chronic kidney diseases. Injury to renal tubular epithelial cell (RTEC) is major link in RIF. Hypoxia is one of the common factors for RTEC damage. Retinoic acid receptors (RARs), RARα, RARβ and RARγ, are evolutionary conserved and pleiotropic proteins that have been involved in various cellular functions, including proliferation, differentiation, apoptosis, and transcription. Recently, we discovered that aberrant expression of RARs was involved in the development of RIF in rats...

Rifampicin (RIF), a typical ligand of human pregnane X receptor (PXR), powerfully induces the expression of cytochrome P450 3A4 (CYP3A4) in humans. Although it is thought that RIF is not a ligand of rodent PXR, treatment with high-dose RIF (e.g., more than 20 mg/kg) increases the expression of CYP3A in the mouse liver. In this study, we investigated whether the induction of CYP3A by high-dose RIF in the mouse liver is mediated via indirect activation of mouse PXR (mPXR). The results showed that high-dose RIF increased the expression of CYP3A11 and other PXR-target genes in the liver of wild-type mice but not PXR-knockout mice...

Housekeeping genes (HKG) are presumed to be constitutively expressed throughout tissue types but recent studies have shown they vary with pathophysiology. Often, validation of appropriate HKG is not made. There is no consensus on which HKGs are most stably expressed in endometrial tissue so this study aimed to identify the most stable HKG in the endometrium of women with recurrent implantation failure (RIF) and recurrent miscarriages (RM). Inclusion criteria were women between 25-45 years (n = 45) suffering recurrent miscarriage (RM), recurrent implantation failure (RIF) or fertile controls...

Xpert MTB/RIF (Xpert) is a widely-used test for tuberculosis (TB) and rifampicin-resistance. Second-line drug susceptibility testing (DST), which is recommended by policymakers, typically requires additional specimen collection that delays effective treatment initiation. We examined whether cartridge extract (CE) from used Xpert TB-positive cartridges was, without downstream DNA extraction or purification, suitable for both genotypic DST (MTBDRplus, MTBDRsl), which may permit patients to rapidly receive a XDR-TB diagnosis from a single specimen, and spoligotyping, which could facilitate routine genotyping...

BACKGROUND: Mycobacterium tuberculosis (MTB) is one of the most significant causes of mortality and morbidity. Early diagnose is important especially in multiple drug resistant tuberculosis to avoid transmission. Traditional techniques requires at least one to three weeks for diagnosis of tuberculosis. Diagnostic delays with multiple drug resistant tuberculosis are associated with worse clinical outcomes and increased transmission The Xpert MTB/RIF assay is one of the new diagnostic device for the diagnosis of tuberculosis and rapid detection of rifampicin resistance...
