(AIMS Press, 2021-09-10)The objective of this study was to elucidate the proteomic mechanisms of drug resistance in HIV-infected African patients. Cell membrane fractions from forty oral Candida isolates isolated from African HIV-positive patients ... -
Human coronavirus NL63 open reading frame 3 encodes a virion-incorporated N-glycosylated membrane protein
(BioMed Central, 2010)Background: Human pathogenic coronavirus NL63 (hCoV-NL63) is a group 1 (alpha) coronavirus commonly associated with respiratory tract infections. In addition to known non-structural and structural proteins all coronaviruses ... -
Human coronavirus NL63: A clinically important virus?
(Future Science Group, 2011)Respiratory tract infection is a leading cause of morbidity and mortality worldwide, especially among young children. Human coronaviruses (HCoVs) have only recently been shown to cause both lower and upper respiratory tract ... -
Human coronavirus research: 20 years since the SARS-CoV outbreak
(Frontiers Media, 2022)This Editorial introduces 10 articles published in a Special Issue highlighting human coronavirus (hCoV) research on the twentieth anniversary of the outbreak of severe acute respiratory syndrome (SARS) in late 2002. ... -
Human coronaviruses: counteracting the damage by storm
(MDPI Viruses, 2021)Over the past 18 years, three highly pathogenic human (h) coronaviruses (CoVs) have caused severe outbreaks, the most recent causative agent, SARS-CoV-2, being the first to cause a pandemic. Although much progress has been ... -
Human sperm handling in intracytoplasmic sperm injection processes: In vitro studies on mouse oocyte activation, embryo development competence and sperm oxidation–reduction potential
(Wiley, 2018)Polyvinylpyrrolidone (PVP) and hyaluronic acid (HA) are routinely used in handling spermatozoa for intracytoplasmic sperm injection (ICSI). As there are still concerns about possible adverse effects on the embryo, this ... -
Identification and characterization of microRNAs expressed in the African malaria vector Anopheles funestus life stages using high throughput sequencing
(BioMed Central, 2016)Background: Over the past several years, thousands of microRNAs (miRNAs) have been identified in the genomes of various insects through cloning and sequencing or even by computational prediction. However, the number of ... -
Identification and characterization of the Trichoplusia ni Single Capsid Nuclear Polyhedrosis Virus p10 gene
(Springer Verlag, 2000)The p10 gene was identified and characterized from the Trichoplusia ni single capsid nuclear polyhedrosis virus (TniSNPV). The p10 open reading frame (ORF) sequence was identified following sequencing of the ends of the ... -
Identification, sequence analysis, and phylogeny of the immediate early gene 1 of the trichoplusia ni single nucleocapsid polyhedrosis virus
(Springer Verlag, 2001)Substantial research has been conducted on the immediate early 1 (ie-1) genes from the prototype baculovirus Autographa californica multicapsid nuclear polyhedrosis virus (AcMNPV) and the Orgyia pseudotsugata multicapsid ... -
Immunological changes during space travel: A ground-based evaluation of the impact of Neutron Dose Rate on Plasma Cytokine levels in human whole blood cultures
(Frontiers Media S.A., 2020)A better understanding of the combined impact of different space stressors on human health is urgently warranted, considering the upcoming long-duration missions beyond lower Earth orbit. Therefore, a growing number of ... -
Impact of body composition analysis on male sexual function: A metabolic age study
(Frontiers Media, 2023)Metabolic Age (MetAge) and body composition analysis may reflect an individual’s metabolic status, which is believed to influence male sexual and gonadal functions. Although erectile dysfunction (ED) and hypogonadism ... -
