The hormone osteocalcin influenced neurodevelopment and cognition in mice models, this human study explored potential associations between total serum levels in human infants and neurodevelopment at four years of age.

The data were based on two Swedish birth cohorts from 2008-09. We followed 158 healthy full-term vaginal births (51% girls), by measuring serum osteocalcin in cord blood and at four, 12 and 36 months. The values were compared to neurodevelopment tests at four years of age.

There was an association between osteocalcin at four months and later full-scale intelligence quotient (IQ) (r
0.031, p<0.05). Children with osteocalcin levels in the highest quartile scored 5.6 (95% confidence interval 1.3 to 9.9) points higher than those in the lowest quartile, with mean scores of 118.8 ±8.8 and 113.2 ±9.2 (p<0.05). They also scored higher on gross motor skills (p<0.05) and showed greater ability during the drawing trail test (p<0.005). Cord levels of osteocalcin were negatively associated with processing speed and fine motor development at four years, but levels at 12 and 36 months were not associated with later neurodevelopment.

Osteocalcin levels in infancy appeared to be associated with later IQ and motor development, but more research is needed.

Blood group genotyping has been used in different populations. This study aims at evaluating the genotypes of common blood group antigens in the Omani blood donors and to assess the concordance rate with obtained phenotypes.

Blood samples from 180 Omani donors were evaluated. Samples were typed by serological methods for the five blood group systems MNS, RH (RHD/RHCE), KEL, FY and JK. Samples were genotyped using RBC-FluoGene vERYfy eXtend kit (inno-train©). Predicted phenotypic variants for 70 red blood cell antigens among the MNS, RH (RHD/RHCE), KEL, FY, JK, DO, LU, YT, DI, VEL, CO and KN blood group systems were assessed.

Simultaneous phenotype and genotype results were available in 130 subjects. Concordance rate was >95% in all blood group systems with exception of Fy(b+) (87%). Homozygous GATA-1 mutation leading to erythroid silencing FY*02N.01 (resulting in the Fy(b-)
phenotype) was detected in 81/112 (72%) of genotyped samples. In addition, discrepant Fy
phenotype/genotype result was obtained in 14/112 samples; 13 of which has a heterozygous GATA-1 mutation and one sample with a wild GATA genotype. D and partial e c.733C>G variants expressing the V+VS+ phenotype were found in 22/121 (18.2%) and 14/120 (11.7%) of the samples, respectively. Di(a-b+), Js(a-b+), Yt(a+b-) and Kn(a+b-) genotype frequencies were 99.4%, 95.8%, 91.9% and 97.7%, respectively.

In conclusion, we report a high frequency of FY*02N.01 allele due to homozygous c.-67T>C GATA-1 single-nucleotide variation. This is the first study reporting the detailed distribution of common and rare red cell genotypes in Omani blood donors.

Here, we use long-term data on over 1800 individually recognizable wild meerkats (Suricata suricatta) collected over 30 years and a multigenerational genetic pedigree to partition phenotypic variation in three cooperative behaviors (babysitting, pup feeding, and sentinel behavior) into individual, additive genetic, and other sources, and to assess their repeatability and heritability. Selleck Epigenetic inhibitor In addition to strong effects of sex, age, and dominance status, we found significant repeatability in individual contributions to all three types of cooperative behavior both within and across breeding seasons. Like most other studies of the heritability of social behavior, we found that the heritability of cooperative behavior was low. However, our analysis suggests that a substantial component of the repeatable individual differences in cooperative behavior that we observed was a consequence of additive genetic variation. Our results consequently indicate that cooperative behavior can respond to selection, and suggest scope for further exploration of the genetic basis of social behavior.Microbial degradation of subsurface organic contaminants is often hindered by the low availability of both contaminants and nutrients, especially phosphorus (P). The use of activated carbon and traditional P fertilizers to overcome these challenges has proved ineffective; therefore, we sought to find an innovative and effective solution. By heating bone meal-derived organic residues in water in a closed reactor, we synthesized nonporous colloids composed of aromatic and aliphatic structures linked to P groups. X-ray absorption near edge spectroscopy analysis revealed that the materials contain mostly bioavailable forms of P (i.e., adsorbed P and magnesium-bearing brushite). The capacity of the materials to adsorb organic contaminants was investigated using benzene and batch isotherm experiments. The adsorption isotherms were fitted to the linearized Freundlich model; isotherm capacity (logKF ) values for the materials ranged between 1.6 and 2.8 μg g-1 . These results indicate that the colloidal materials have a high affinity for organic contaminants. This, coupled with their possession of bioavailable P, should make them effective amendments for in situ groundwater bioremediation. Also, the materials' chemical properties suggest that they are not recalcitrant, implying that they will not become potential contaminants when released into the environment.
Gas ventilation is inhomogeneous in the lung of many species. However, it is not known down to what length scales this inhomogeneity persists. It is generally assumed that ventilation becomes homogenous at subacinar length scales, beyond the spatial resolution of available imaging techniques. Here we imaged the distribution of inhaled Xe gas in the rabbit lung using synchrotron radiation energy-subtractive imaging. We apply fractal analysis to show that ventilation becomes internally uniform within regions about the size of rabbit lung acini.

Ventilation is inhomogeneous in the lungs across species. It has been hypothesized that ventilation inhomogeneity is largely determined by the design of the airway branching network. Because exchange of gases at the alveolar barrier is more efficient when gas concentrations are evenly distributed at subacinar length scales, it is assumed that a "functional unit" of ventilation exists within the lung periphery, where gas concentration becomes uniform. On the other hanfunctional unit of ventilation. However, the existence of such a functional unit has never been demonstrated experimentally due to lack of in situ gas concentration measurements of sufficient spatial resolution in the periphery of a complex bifurcating network. Here, using energy-subtractive synchrotron radiation tomography, we measured the distribution of an inert gas (Xe) in the in vivo rabbit lung during Xe washin breathing manoeuvres. The effects of convective flow rate, diffusion, and cardiac motion were also assessed. Fractal analysis of resulting gas concentration and tissue-density maps revealed that fractal dimension was always smaller for Xe than for tissue density, and that only for the gas, a length scale existed where fractal dimension approached unity. The length scale where this occurred was seen to correspond to that of a rabbit acinus, the terminal structure comprising only alveolated airways. This article is protected by copyright.

The aim of this study was to characterise the response rate and toxicity profile of cyclophosphamide and prednisolone given to dogs with newly diagnosed, chemotherapy naïve, B cell multicentric lymphoma.

Dogs with diagnosed with B cell lymphoma naïve to chemotherapy treatment were prospectively identified at the author's institution (2017 to 2021) and given cyclophosphamide as their initial chemotherapeutic agent in combination with prednisolone with owner's consent. Signalment, laboratory findings, stage, treatment response and toxicity were recorded.

Thirty-two dogs were included in the study. The overall response rate in this population of dogs was 84%. Twenty dogs (62%) had a partial response, three dogs (9%) had a complete response, four dogs (12%) had stable disease and five dogs (15%) had progressive disease. Side effects were noted in 47% of patients, with neutropaenia being the most commonly reported.

Cyclophosphamide and prednisolone were well-tolerated with limited side effects. The response rate observed in this cohort of dogs with chemotherapy-naïve B cell multicentric lymphoma is promising. Further comparative studies are required to confirm the safety and effectiveness of this intervention.

We assembled a multidisciplinary group of editors and researchers with expertise in international health research to develop this consensus statement. We reviewed relevant existing literature and held three workshops to present research data and holistically discuss the concept of equitable authorship and the role of academic journals in the context of international health research partnerships. We subsequently developed statements to guide prospective authors and journal editors as to how they should address this issue. We recommend that for manuscripts that report research conducted in low- or middle-income countries by collaborations including partners from one or more high-income countries, authors should submit accompanying structured reflexivity statements. We provide specific questions that these statements should address and suggest that journals should transparently publish reflexivity statements with accepted manuscripts. We also provide guidance to journal editors about how they should assess the structured statements when making decisions on whether to accept or reject submitted manuscripts. We urge journals across disciplines to adopt these recommendations to accelerate the changes needed to halt the practice of parachute research.
Reflection is one of four components of the experiential learning cycle and is often the one overlooked. This practice can be used in graduate-level health care education, such as medicine and dentistry. This metacognitive practice allows students to conceptualize learning in a clinical setting and apply this knowledge to new scenarios. Reflective practice can be taught using different modalities of narrative medicine, and several studies have studied its effectiveness in areas such as professional development, collaboration, communication among others. Most of these studies, however, have been conducted solely in the medical setting, and narrative medicine may have useful application in the practice and teaching of dentistry.

This literature review examined the outcomes of narrative medicine in medical studies concerning reflection and hypothesized their benefits to dental education. The studies reviewed were chosen by utilizing key term searches of the National Center for Biotechnology Information PubMed library and qualitative factor analysis by study team investigators.
