Human alkyladenine DNA glycosylase (AAG) initiates base excision repair (BER) to guard against mutations by excising alkylated and deaminated purines. Counterintuitively, increased expression of AAG has been implicated in increased rates of spontaneous mutation in microsatellite repeats. This microsatellite mutator phenotype is consistent with a model in which AAG excises bulged (unpaired) bases, altering repeat length. To directly test the role of base excision in AAG-induced mutagenesis, we conducted mutation accumulation experiments in yeast overexpressing different variants of AAG and detected mutations via high-depth genome resequencing...

BACKGROUND: The presence of skilled birth attendants (SBAs) is crucial in childbirth to reduce the maternal mortality ratio (MMR) and to achieve the maternal mortality target of the United Nations' Sustainable Development Goals (SDGs). The aim of this study was to investigate the factors related to childbirths attended by SBAs in Bangladesh. METHODS: Data from the Bangladesh Demographic and Health Survey (2014 BDHS) were analyzed. Logistic regression was applied to calculate crude odds ratios (CORs), adjusted odds ratios (AORs), 95% confidence intervals (CIs), and p-values...

BACKGROUND: Oddball paradigms are frequently used to study auditory discrimination by comparing event-related potential (ERP) responses from a standard, high probability sound and to a deviant, low probability sound. Previous research has established that such paradigms, such as the mismatch response or mismatch negativity, are useful for examining auditory processes in young children and infants across various sleep and attention states. The extent to which oddball ERP responses may reflect subtle discrimination effects, such as speech discrimination, is largely unknown, especially in infants that have not yet acquired speech and language...

Categorized as a Biopharmaceutics Classification System (BCS) Class II drugs, statin exhibit low aqueous solubility and bioavailability thus presenting an obstacle and great challenge to formulation researchers. This paper describes a de novo approach to enhance the aqueous solubility of one of the most commonly prescribed statins i.e. simvastatin (SMV) by forming a complex (SMV-ARG) with cosolute arginine (ARG). The complex has been characterized for its apparent solubility and in vitro dissolution. The solid state characterization has been carried out using Fourier Transform Infra-Red (FTIR) Spectroscopy, Elemental Analysis, X-Ray Powder Diffraction (XRD), Differential Scanning Calorimetry (DSC) analysis, Thermal Gravimetric Analysis (TGA) and Scanning Electron Microscopy (SEM)...

Egg allergy is one of the most common food allergies during childhood along with cow's milk allergy. The measles-mumpsrubella (MMR) vaccine is included in the pediatric immunization schedule and contains egg protein. The currently accepted opinion is that the MMR vaccination should be done in a single dose under medical observation in patients with egg allergy. Although it is reported that the MMR vaccine is safe for that patients, there are some patients who developed anaphylaxis. Generally, the development of anaphylaxis after the previous vaccination is reported as a contraindication...

BACKGROUND/AIM: Total mesorectal excision combined with neo-adjuvant chemoradiotherary (CRT) and adjuvant chemotherapy, has been the standard treatment of locally advanced rectal cancer (LARC). Although TNM (Tumor, Node, Metastasis) classification for malignant Tumors is still the cornerstone in rectal cancer staging, there has been an effort to identify molecular biomarkers with additional prognostic or predictive value. MATERIALS AND METHODS: We retrospectively analyzed molecular biomarkers on prospectively collected histological specimens and clinical data from a cohort of 135 consecutive rectal cancer cases who underwent radical excision in a tertiary center between 2011-2014 (males=87, females=48, age range=22-89 years, mean=64,67 years, SD=13...

Accumulating evidence indicates that immune checkpoint inhibition-mediated cancer immunotherapies greatly improve the prognosis of certain types of cancer. This approach is now becoming a standard therapy, joining surgery, radiotherapy, and chemotherapy. Because the costs of antibody drugs are now a socioeconomic burden in many countries, an urgent need in cancer immunotherapy is the identification of relevant biomarkers that can predict therapy efficacy. Recent studies have reported that colorectal adenocarcinoma with hereditary or sporadic deficiency in mismatch repair (MMR) proteins has high antigenicity and that detection of these proteins could be a promising way to estimate clinical response...

Following the introduction of measles-rubella (MR) catch-up vaccination in 2001 and two dose measles-mumps-rubella (MMR2) keep-up program in 2002, the incidence of measles, mumps and rubella was not evaluated systematically. To describe the recent changes in epidemiology, a population based incidence study from 2001 to 2015 using national notifiable disease surveillance data was conducted. Between 2001 and 2015, there was decrease in the incidence of measles and rubella, whereas a steady increase in mump incidence was noted...

INTRODUCTION: The Mortality Surveillance Division (MSD) of the U.S. Armed Forces Medical Examiner System was established in 1998 to improve surveillance for all military deaths although emphasizing deaths from infectious diseases. Establishment of the MSD was part of the 1997 Department of Defense initiative to improve surveillance and response for emerging infectious diseases. Before 1998, mortality surveillance was limited to compiling information from death certificates, a system that provided limited useful information and lacked the timeliness needed to take meaningful action to address emerging infectious disease threats...

Population-based studies have revealed 2-10% measles vaccine failure rate even after two vaccine doses. While the mechanisms behind this remain unknown, we hypothesized that host genetic factors are likely to be involved. We performed a genome-wide association study of measles specific neutralizing antibody and IFNγ ELISPOT response in a combined sample of 2872 subjects. We identified two distinct chromosome 1 regions (previously associated with MMR-related febrile seizures), associated with vaccine-induced measles neutralizing antibody titers...

During somatic hypermutation (SHM) of immunoglobulin genes, uracils introduced by activation-induced cytidine deaminase are processed by uracil-DNA glycosylase (UNG) and mismatch repair (MMR) pathways to generate mutations at G-C and A-T base pairs, respectively. Paradoxically, the MMR-nicking complex Pms2/Mlh1 is apparently dispensable for A-T mutagenesis. Thus, how detection of U:G mismatches is translated into the single-strand nick required for error-prone synthesis is an open question. One model proposed that UNG could cooperate with MMR by excising a second uracil in the vicinity of the U:G mismatch, but it failed to explain the low impact of UNG inactivation on A-T mutagenesis...

Alkylating agents are known to induce the formation of O(6)-alkylguanine (O(6)-alkG) and O(4)-alkylthymine (O(4)-alkT) in DNA. These lesions have been widely investigated as major sources of mutations. We previously showed that mismatch repair (MMR) facilitates the suppression of GC-to-AT mutations caused by O(6)-methylguanine more efficiently than the suppression of GC-to-AT mutations caused by O(6)-ethylguanine. However, the manner by which O(4)-alkyT lesions are repaired remains unclear. In the present study, we investigated the repair pathway involved in the repair of O(4)-alkT...

In chronic myeloid leukemia (CML) patients, 3-month BCR-ABL1 levels have consistently been correlated with further outcomes. Monitoring molecular responses in CML using the GeneXpert (Cepheid) platform has shown an optimal correlation with standardized RQ-PCR (IS) when measuring BCR-ABL1 levels lower than 10%, as it is not accurate for values over 10%. The aim of the present study was to determine the predictive molecular value at three months on different outcome variables using the Xpert BCR-ABL1 MonitorTM assay (Xpert BCR-ABL1)...
