In this review, we elaborate the potential effect of circadian rhythm disorder in vascular calcification and try to provide a new direction in the prevention of vascular calcification.Osteocalcin, the osteoblast-derived protein, has been shown to be modulated in patients with problematic glucose metabolism. Our systematic review and meta-analysis found that in humans, higher blood osteocalcin level is associated with lower body indices of fat.

Osteocalcin (OC) was found to be inversely correlated with measures of glucose and energy metabolism, with some groups suggesting the undercarboxylated form (ucOC) to be metabolically active, although the link is not clear, especially in humans. Given obesity is a major risk factor for metabolic disorders, we aimed to assess the correlation between OC and two measures of body weight body mass index (BMI) and percentage body fat (%BF).

MEDLINE and EMBASE were searched to identify observational studies in adult populations that reported the crude correlation coefficients (r) between OC and BMI and %BF. Pool r were obtained using random-effects models.

Fifty-one publications were included in this analysis. Both total OC (TOC) (pooled r = - 0.151, 95% CI -0.17, - 0.130; I

= 52%) and ucOC (pooled r = - 0.060, 95% CI -0.103, - 0.016; I

= 54%) were inversely correlated with BMI. The pooled r between TOC and BMI in Caucasian-and-other-regions (r = - 0.187) were stronger than those in Asian populations (r = - 0.126; intra-group p = 0.002; R

 = 0.21). GPCR agonist The mean/median BMI of the reported cohort was the major contributor to between-study heterogeneity in correlation between TOC/ucOC and BMI (R

 = 0.28 and 0.77, respectively). Both TOC and ucOC were also inversely correlated with %BF (TOC pooled r = - 0.185, 95% CI -0.257 to - 0.112; ucOC pooled r = - 0.181, 95% CI -0.258 to - 0.101).

Higher OC and ucOC were correlated with lower BMI and %BF. The inverse correlations between TOC/ucOC and BMI appear to be affected by ethnicity and obesity status.

It was shown that if organic catalysts were abundant, then effective averaging of enantioselectivity would prohibit any symmetry breaking in such systems. It was further argued that non-linear (catalytic) reactions must be very scarce (called the abundance parameter) and catalysts should work on small groups of similar reactions (called the similarity parameter) in order to chiral symmetry breaking have a chance to occur. Models with 20 amino acids and peptide lengths up to three were considered. It was shown that there are preferred ranges of abundance and similarity parameters where the symmetry breaking can occur in the models with catalytic synthesis / catalytic destruction / both catalytic synthesis and catalytic destruction. It was further shown that models with catalytic synthesis and catalytic destruction statistically result in a substantially higher percentage of the models where the symmetry breaking can occur in comparison to the models with just catalytic synthesis or catalytic destruction. It was also shown that when chiral symmetry breaking occurs, then concentrations of some amino acids, which collectively have some mutually beneficial properties, go up, whereas the concentrations of the ones, which don't have such properties, go down. An open source code of the whole system was provided to ensure that the results can be checked, repeated, and extended further if needed.

Cisplatin has been established as one of the most important agents in multidisciplinary treatment for head and neck cancer (HNC). However, since HNC patients are often elderly and typically have several comorbidities, a limited number of patients can tolerate high-dose cisplatin in real-world HNC populations. We will provide a review of therapeutic alternatives to high-dose cisplatin-based treatment in the setting of definitive and postoperative chemoradiotherapy (CRT) or induction chemotherapy.

Clinical criteria for CDDP ineligibility have been discussed in HNC. When considering cisplatin-based chemotherapy as part of a non-surgical approach, precise evaluation of the patient's physical condition, nutritional status, and comorbidities is needed. Upfront surgery is an important option with high curability, if a de-intensified non-surgical approach is estimated to be unavoidable. Although no prospective data are available regarding alternatives to definitive cisplatin-based combination therapy for patientsis an important option with high curability, if a de-intensified non-surgical approach is estimated to be unavoidable. Although no prospective data are available regarding alternatives to definitive cisplatin-based combination therapy for patients undergoing a non-surgical approach, cetuximab, carboplatin, or split-dose cisplatin-based regimens may be employed for cisplatin-ineligible patients in clinical practice. The combination of immune checkpoint inhibitors with radiotherapy may be a promising novel approach, and some trials are currently targeting the specific cohort of patients ineligible for high-dose cisplatin. There are no standard treatments for patients ineligible for high-dose cisplatin. A personalized treatment strategy should be proposed based on the individual benefit-to-risk ratio of each treatment option in patients ineligible for the standard of care. Prospective clinical trials for cisplatin-ineligible patients with locally advanced HNC still need to be performed.A plethora of neuroimaging studies have focused on the discovery of potential neuroendophenotypes useful to understand the etiopathogenesis of autism and predict treatment response. Social robotics has recently been proposed as an effective tool to strengthen the current treatments in children with autism. However, the high clinical heterogeneity characterizing this disorder might interfere with behavioral effects. Neuroimaging is set to overcome these limitations by capturing the level of heterogeneity. Here, we provide a preliminary evaluation of the neural basis of social robotics and how extracting neural hallmarks useful to design more effective behavioral applications. Despite the endophenotype-oriented neuroimaging research approach is in its relative infancy, this preliminary evidence encourages innovation to address its current limitations.
