The ubiquitous SbcCD exonuclease complex has been shown to perform an important role in DNA repair across prokaryotes and eukaryotes. However, they have remained uncharacterized in the ancient and stress-tolerant cyanobacteria. In the cyanobacterium Anabaena sp. strain PCC7120, SbcC and SbcD homologs, defined on the basis of the presence of corresponding functional domains, are annotated as hypothetical proteins, namely Alr3988 and All4463 respectively. Unlike the presence of sbcC and sbcD genes in a bicistronic operon in most organisms, these genes were distantly placed on the chromosome in Anabaena, and found to be negatively regulated by LexA...

Traditional yellow maize though contains high kernel carotenoids, the concentration of provitamin A (proA) is quite low (<2 μg/g), compared to recommended level (15 μg/g). It also possesses poor endosperm protein quality due to low concentration of lysine and tryptophan. Natural variant of crtRB1 (β -carotene hydroxylase ) and lcyE ( lycopene- ε -cyclase ) cause significant enhancement of proA concentration, while recessive allele, opaque2 ( o2 ) enhances the level of these amino acids. Development of biofortified maize enriched in proA, lysine and tryptophan thus holds significance in alleviation of micronutrient malnutrition...

Mucormycosis or zygomycosis, also called phycomycosis, is an uncommon, invasive, potentially lethal and an aggressive fungal infection of the order Mucorales that usually affects patients with alteration of their immunological system. From its initial description (Paltauf, 1885), this entity still has a high mortality. Imaging techniques are not usually diagnostic, and cultures are not totally reliable. Definitive diagnosis is exclusively obtained by means of histopathological examination. Early recognition and aggressive treatment are of paramount importance and have reduced the mortality and morbidity...

Melanotic neuroectodermal tumor of infancy is a rare benign but locally aggressive neoplasm of neural crest origin with a high recurrence rate. It usually affects infants of < 1 year of age. Involvement of maxilla of an infant is the most common presentation although cases outside this setting have been reported. We report the case of a 6-month-old male child presenting with intraoral swelling. Radiologically, a tumor was detected in the right maxilla, and wide local excision was done. Histological examination revealed typical biphasic population of cells with deposits of melanin pigment...

BACKGROUND: Inadequate antenatal care (ANC) can lead to missed diagnosis of danger signs or delayed referral to emergency obstetrical care, contributing to maternal mortality. In developing countries, ANC quality is often limited by skill and knowledge gaps of the health workforce. In 2011, the Mentorship, Enhanced Supervision for Healthcare and Quality Improvement (MESH-QI) program was implemented to strengthen providers' ANC performance at 21 rural health centers in Rwanda. We evaluated the effect of MESH-QI on the completeness of danger sign assessments...

The amphiphilic monomer 2-hydroxyethyl methacrylate (HEMA) is widely used in dental adhesives as a priming component, especially for dentin bonding. It behaves as a compatibilizer between hydrophilic and hydrophobic components, and stabilizes the multi-component adhesive system. However, there are several drawbacks associated with using HEMA, such as water retention within the adhesive layer, hydrolysis in oral environments, and cytotoxicity. These drawbacks lead to the failure of tooth restoration and represent a heavy medical burden...

A few decades ago, the chances of survival for patients with a haematological malignancy needing Intensive Care Unit (ICU) support were minimal. As a consequence, ICU admission policy was cautious. We hypothesized that the long-term outcome of patients with a haematological malignancy admitted to the ICU has improved in recent years. Furthermore, our objective was to evaluate the predictive value of the Acute Physiology and Chronic Health Evaluation (APACHE) II score. A total of 1095 patients from 5 Dutch university hospitals were included from 2003 until 2015...

Recently high density (HD) nonmagnetic cobalt has been discovered in a nanoscale cobalt thin film, grown on Si(111) single crystal. This form of cobalt is not only nonmagnetic but also superconducting. These promising results have encouraged further investigations of the growth of the nonmagnetic (NM) phase of cobalt. In the original investigation, the cobalt film had a natural cobalt oxide at the top. We have investigated whether the growth of HD NM cobalt layers in the thin film depends on (i) a capping layer on the cobalt film, (ii) the thickness of the cobalt film and (iii) the nature of the substrate on which the cobalt film is grown...
