In conclusion, the 20mSRT-music is feasible and presents a good concurrent validity in adolescents, independently of the sex and it will be an alternative and good approach to assess cardiorespiratory fitness.Cancer is a major public health burden worldwide, affecting millions of people each year. One of the major hallmarks of cancer is rapid growth and progression by evasion of host immune responses. Tumor resistance to conventional anticancer drugs by several mechanisms, such as drug inactivation, efflux pumps and enhanced toxicity to normal cells decreases their clinical efficacy. These limitations resulted in the development of new targeted agents, such as monoclonal antibodies and small molecule inhibitors that have high tumor specificity. This paper discusses the therapeutic applications of novel molecular targeted agents and immunotherapy as an alternative treatment option for head and neck cancers, as well as provides insight into future therapeutic approaches for advanced head and neck cancers.Background Congenital hypothyroidism due to thyroid dysgenesis is a frequent congenital endocrine disorder for which the molecular mechanisms remain unresolved in the majority of cases. This situation reflects, in part, our still limited knowledge about the mechanisms involved in the early steps of thyroid specification from the endoderm, in particular the extrinsic signaling cues that regulate foregut endoderm patterning. In this study, we used small molecules and genetic zebrafish models to characterize the role of various signaling pathways in thyroid specification. Methods We treated zebrafish embryos during different developmental periods with small-molecule compounds known to manipulate the activity of Wnt signaling pathway and observed effects in thyroid, endoderm, and cardiovascular development using whole-mount in situ hybridization and transgenic fluorescent reporter models. We used the antisense morpholino (MO) technique to create a zebrafish acardiac model. For thyroid rescue experiments, bone morphogenetic protein (BMP) pathway induction in zebrafish embryos was obtained by manipulation of heat-shock inducible transgenic lines. Results Combined analyses of thyroid and cardiovascular development revealed that overactivation of Wnt signaling during early development leads to impaired thyroid specification concurrent with severe defects in the cardiac specification. When using a model of MO-induced blockage of cardiomyocyte differentiation, a similar correlation was observed, suggesting that defective signaling between cardiac mesoderm and endodermal thyroid precursors contributes to thyroid specification impairment. Rescue experiments through transient overactivation of BMP signaling could partially restore thyroid specification in models with defective cardiac development. Conclusion Collectively, our results indicate that BMP signaling is critically required for thyroid cell specification and identify cardiac mesoderm as a likely source of BMP signals.This work evaluates the performance of activated carbon obtained from sugarcane straw (SCAC) as an adsorbent for polyaromatic hydrocarbons (PAHs) present in model wastewater. Two commercial samples of activated carbons with different textural properties were also studied for comparison. The activated carbon prepared from sugarcane straw presents a well-developed porosity with a high surface area, which was comparable to that of one of the commercial samples studied. For all the studied carbons, adsorption followed pseudo-second-order kinetics, and the higher rate constants were found for the SCAC sample for the four PAHs. Sips and Hill isotherms best fitted the adsorption equilibrium data of the PAHs on all activated carbons investigated. The activated carbon obtained from sugarcane straw (SCAC) presented a higher adsorption capacity (2.08 mmol g-1 for naphthalene, 1.26 mmol g-1 for fluorene, 1.14 mmol g-1 for phenanthrene, and 0.98 mmol g-1 for fluoranthene) when compared to the commercial carbon samples studied in this work as well as for those related in the literature. It confirms that its use of SCAC as an adsorbent for PAHs is a promising application for the valorization of this biomass waste.

To describe drug-induced sleep endoscopy (DISE) findings in children with obstructive sleep apnea and to differentiate them between surgically naïve children and children who had adenotonsillectomy performed.

Retrospective case series with chart review.

Secondary care hospital.

A cohort of 56 children with the diagnosis of obstructive sleep apnea was submitted to DISE and subsequent upper airway surgery 23 were surgically naïve, and 33 had persistent obstructive sleep apnea after adenotonsillectomy. Comparisons between groups were calculated with chi-square test and Student's

test. Simple linear regression was used to model polysomnographic indices.

In surgically naïve children, the most common sites of obstruction were the adenoids (78.2%) and the lateral pharyngeal walls/tonsils (82.6%). In children with persistent obstructive sleep apnea after adenotonsillectomy, the most common sites of obstruction were the adenoids (54.5%), followed by the supraglottis (48.5%) and the tongue base (45.5%).

Preparation of del-Nido cardioplegia and its delivery technique can cause significant hemodilution. The resultant effects from hemodilution are largely proportionate to the use of a dual circuit. We opted for a custom-disposable single cardioplegia circuit instead of a dual circuit.

We describe an alternative technique of del-Nido cardioplegia delivery and initial clinical experience with it at National University Hospital, Singapore. This is a retrospective analysis of data from January 2017 to April 2019, comprising of 177 patients of heart surgery and reflecting a single center database survey under the National Health Care Group.

Of the 177 patients who underwent surgery with del-Nido cardioplegia, 76 (42.9%) were valve-only procedures and 5 (2.8%) were coronary artery bypass graft-only procedures. Ultrafiltration was utilized in 132 (62.6%) patients, whereas filtrate volume was 2200 [150-9500] mL. The alternative technique of del-Nido cardioplegia delivery adopted by National University Hospital advocates for a single pump, single circuit system.
