Mature microRNA is a crucial component in the gene expression regulation network. At the same time, microRNA gene expression and procession is regulated in a precise and collaborated way. Pre-microRNAs mediate products during the microRNA transcription process, they can provide hints of microRNA gene expression regulation or can serve as alternative biomarkers. To date, little effort has been d...

The study aimed to determine correlates of gestational weight gain and infant birth weight of pregnant women attending antenatal clinics in public primary health care facilities in lfe Central and East Local Government Areas of Osun State, Nigeria. Over 1000 women were recruited during booking and antenatal clinic and followed up till delivery. Chi square was used in the bivariate analysis of a...

The current outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)in China threatened humankind worldwide. The coronaviruses contains the largest RNA genome among all other known RNA viruses, therefore the disease etiology can be understood by analyzing the genome sequence of SARS-CoV-2. In this study, we used an ab-intio based computational tool VMir to scan the complete geno...

Breastmilk protects infants against infections; however, specific responses of breastmilk immune factors to different infections of either the mother or the infant are not well understood. Here, we examined the baseline range of breastmilk leukocytes and immunomodulatory biomolecules in healthy mother/infant dyads and how they are influenced by infections of the dyad. Consistent with a greater ...

BACKGROUND Mature miRNAs can often be classified into large families, consisting of members with identical seeds (nucleotides 2 through 7 of the mature miRNAs) and highly homologous approximately 21-nucleotide (nt) mature miRNA sequences. However, it is unclear whether members of a miRNA gene family, which encode identical or nearly identical mature miRNAs, are functionally interchangeable in v...

CONFLICT OF INTEREST NONE DECLARED. INTRODUCTION Teratomas are derived from embryonic tissues that are typically found in the gonadal and sacrococcygeal regions of adults and children. Primary teratomas in the retroperitoneum are very rare in infant and primary adrenal teratomas are extremely rare. Early diagnosis and surgical resection are important for effective treatment. CASE REPORT We ...

conclusions hbv in children due to vaccination failure was resulted from vertical transmission. hbv pre-s/s gene mutations were prevalent and could occur before or after vaccination. therefore, simply analyzing mutation frequency of hbv gene was not of value. to advance blocking hbv vertical transmission, future studies should focus on specific mutation sites, potentially associated with vaccin...

The RNA-protein subunit assembly of nuclear RNase P was investigated by specific isolation and characterization of the precursor and mature forms of RNase P using an RNA affinity ligand. Pre-RNase P was as active in pre-tRNA cleavage as mature RNase P, although it contained only seven of the nine proteins found in mature RNase P. Pop3p and Rpr2p were not required for maturation of the RPR1 RNA ...
