Multiple myeloma (MM) is characterized as a clonal expansion of malignant plasma cells in the bone marrow, which is often associated with pancytopenia and osteolytic bone disease. Interestingly, myeloma-infiltrated bone marrow is considered to be hypoxic, providing selection pressure for a developing tumour. Since HSP90 was shown to participate in stabilization of the subunit of the key transcription factor HIF-1, which controls the hypoxic response, the aim of this study was to investigate the influence of a HSP90 inhibitor 17-Allylamino-17-demethoxygeldanamycin (17-AAG), on MM cells cultured under low oxygenation conditions...

OBJECTIVE: It is difficult to critically outline the optimal treatment for women with early-stage cervical cancer (eCC) wishing fertility preservation. Neoadjuvant chemotherapy (NAC) to downstage "bulky" eCC could potentially lead to fertility-sparing surgery (FSS) in a wider patient population. The rationale is to provide oncological safety balanced with maximal fertility effort. We aimed to obtain the most accurate fertility outcomes for eCC women treated with NAC followed by FSS and identify potential factors favoring fertility...

The international community has set forth global targets that include calls for universal access to high-quality early childhood care and education (ECCE), as indicated in the United Nations' Sustainable Development Goals. One major impediment to achieving this target is the lack of a skilled workforce. In this paper, we argue the case for leveraging youth as an untapped resource for supplying the workforce the ECCE system needs. Youth comprise a large proportion of the global population, and historically, although youth experience higher unemployment rates than their adult counterparts, youth are important agents of social awareness, social transformation, and community mobilization in multiple global contexts...

BACKGROUND: Circular caries occurs in the earliest age of the children (1 - 1.5 year), immediately after the eruption of the deciduous teeth. During this period, children are too young to be able to properly implement oral hygiene. Consequently, it is at a negligible level, with plenty of soft plaque on the deciduous tooth surfaces. OBJECTIVE: The main objective of this clinical trial was to determine the correlation between oral hygiene shown with Oral Hygiene index, and the initial stages of circular caries (initial lesion and superficial form), before and after topical fluoride treatment...

PURPOSE: Physical activity is an important part of life, and exercise-induced asthma (EIA) can reduce the quality of life. A standardized exercise challenge is needed to diagnose EIA, but this is a time consuming, effortful and expensive method. Exhaled nitric oxide (eNO) as a marker of eosinophil inflammation is determined rapidly and easily. The aim of this study was to investigate eNO as surrogate marker for predicting a positive reaction in an exercise challenge in a cold chamber (ECC)...

PURPOSE: Cardiac surgery and conventional extracorporeal circulation (CECC) impair the bioavailability of drugs administered by mouth. It is not known whether miniaturized ECC (MECC) or off-pump surgery (OPCAB) affect the bioavailability in similar manner. We evaluated the metoprolol bioavailability in patients undergoing CABG surgery with CECC, MECC, or having OPCAB. METHODS: Thirty patients, ten in each group, aged 44-79 years, scheduled for CABG surgery were administered 50 mg metoprolol by mouth on the preoperative day at 8-10 a...

Acid resistance is one of key properties assisting the survival of cariogenic bacteria in a dental caries environment, but only a few genes conferring acid resistance have been identified to data. Functional metagenomics provides a systematic method for investigating commensal DNA to identify genes that encode target functions. Here, the host strain Escherichia coli DH10B and a constructed bidirectional transcription vector pSKII+ -lacZ contributed to the construction of a metagenomic library, and 46.6 Mb of metagenomic DNA was cloned from carious supragingival plaque of 8children along with screening for lethal functionality...

Membrane transporters play an important role in the absorption, distribution, clearance and elimination (ADCE) of the drugs. Supported by the pharmacokinetics data in human, several transporters including organic anion transporting polypeptide (OATP)1B1, OATP1B3, organic anion transporter (OAT)1, OAT3, organic cation transporter (OCT)2, multidrug and toxin extrusion proteins (MATEs), P-glycoprotein and breast cancer resistance protein (BCRP) are suggested to be of clinical relevance. An early understanding of transporters role in the drug disposition and clearance allows reliable prediction/evaluation of the pharmacokinetic changes due to drug-drug interactions (DDIs) or genetic polymorphisms...

Compared to conventional concrete, polyvinyl alcohol fiber reinforced engineering cementitious composite (PVA-ECC) offers high-strength, ductility, formability, and excellent fatigue resistance. However, impact-induced structural damage is a major concern and has not been previously characterized in PVA-ECC structures. We investigate the damage of PVA-ECC beams under low-velocity impact loading. A series of ball-drop impact tests were performed at different drop weights and heights to simulate various impact energies...

Infant oral health (IOH) is a preventive service advocated by major medical and dental organizations. IOH aims to prevent early childhood caries (ECC) and impart health strategies to families for continued oral health and prevention of future caries. IOH reaches across disciplines, is low cost, and is covered by Medicaid and many private dental payers. Increasing evidence points to immediate and long-term positive oral health outcomes of reduced disease, reduction in costly care, and reduction in ECC-associated morbidities...

Sigma factors are bacterial transcription factors that bind the core RNA polymerase and direct transcription initiation at a specific promoter site. These specialized sigma factors bind the promoters of genes appropriate to the environmental conditions and selectively increase the transcription of those genes. Here, we attempt to identify sigma factors in 5 genomes belonging to the Enterobacter cloacae complex (Ecc), a group of gram-negative bacteria that are important nosocomial pathogens. This process includes the identification of orthologous sequences, conserved motifs, domains, families, phylogenetic profiles, and protein-protein associations of these components...

The shortening of sarcomeres that co-ordinates the pump function of the heart is stimulated by electrically-mediated increases in [Ca2+ ]. This process of excitation-contraction coupling (ECC) is subject to modulation by neurohormonal mediators that tune the output of the heart to meet the needs of the organism. Endothelin-1 (ET-1) is a potent modulator of cardiac function with effects on contraction amplitude, chronotropy and automaticity. The actions of ET-1 are evident during normal adaptive physiological responses and increased under pathophysiological conditions, such as following myocardial infarction and during heart failure, where ET-1 levels are elevated...
