Abstract
Paradise fish (Macropodus opercularis) is an air-breathing freshwater fish species with a signature labyrinth organ capable of extracting oxygen from the air that helps these fish to survive in hypoxic environments. The appearance of this evolutionary innovation in anabantoids resulted in a rewired circulatory system, but also in the emergence of species-specific behaviors, such as territorial display, courtship and parental care in the case of the paradise fish. Early zoologists were intrigued by the structure and function of the labyrinth apparatus and a series of detailed descriptive histological studies at the beginning of the 20th century revealed the ontogenesis and function of this specialized system. A few decades later, these fish became the subject of numerous ethological studies, and detailed ethograms of their behavior were constructed. These latter studies also demonstrated a strong genetic component underlying their behavior, but due to lack of adequate molecular tools, the fine genetic dissection of the behavior was not possible at the time. The technological breakthroughs that transformed developmental biology and behavioral genetics in the past decades, however, give us now a unique opportunity to revisit these old questions. Building on the classic descriptive studies, the new methodologies will allow us to follow the development of the labyrinth apparatus at a cellular resolution, reveal the genes involved in this process and also the genetic architecture behind the complex behaviors that we can observe in this species.

Abstract
Over the decades, a small number of model species, each representative of a larger taxa, have dominated the field of biological research. Amongst fishes, zebrafish (Danio rerio) has gained popularity over most other species and while their value as a model is well documented, their usefulness is limited in certain fields of research such as behavior. By embracing other, less conventional experimental organisms, opportunities arise to gain broader insights into evolution and development, as well as studying behavioral aspects not available in current popular model systems. The anabantoid paradise fish (Macropodus opercularis), an "air-breather" species from Southeast Asia, has a highly complex behavioral repertoire and has been the subject of many ethological investigations, but lacks genomic resources. Here we report the reference genome assembly of Macropodus opercularis using long-read sequences at 150-fold coverage. The final assembly consisted of ≈483 Mb on 152 contigs. Within the assembled genome we identified and annotated 20,157 protein coding genes and assigned ≈90% of them to orthogroups. Completeness analysis showed that 98.5% of the Actinopterygii core gene set (ODB10) was present as a complete ortholog in our reference genome with a further 1.2 % being present in a fragmented form. Additionally, we cloned multiple genes important during early development and using newly developed in situ hybridization protocols, we showed that they have conserved expression patterns.

Abstract
The present study investigated whether the length of interbirth intervals between first and second-born children in a North-American middle-class sample could be explained by paternal and alloparental support and firstborn children's gender. The sample consisted of 225 families in which mothers were expecting their second child. Parents reported on paternal and alloparental support (maternal kin, paternal kin, and non-kin support). The results showed that higher maternal kin support and having a firstborn son was linked with shorter interbirth-intervals. Mothers' longer work hours during the pregnancy with the second born was related to longer interbirth intervals. These results highlight the importance of maternal kin support and children's characteristics in understanding the timing of birth when parents have a second child.

Abstract
In the Mycobacterium genus over one hundred species are already described and new ones are periodically reported. Species that form colonies in a week are classified as rapid growers, those requiring longer periods (up to three months) are the mostly pathogenic slow growers. More recently, new emerging species have been identified to lengthen the list, all rapid growers. Of these, Mycobacterium abscessus is also an intracellular pathogen and it is the most chemotherapy-resistant rapid-growing mycobacterium. In addition, the cases of multidrug-resistant Mycobacterium tuberculosis infection are also increasing. Therefore there is an urgent need to find new active molecules against these threatening strains. Based on previous results, a series of salicylanilides, salicylanilide 5-chloropyrazinoates and carbamates was designed, synthesized and characterised. The compounds were evaluated for their in vitro activity on M. abscessus, susceptible M. tuberculosis H37Rv, multidrug-resistant (MDR) M. tuberculosis MDR A8, M. tuberculosis MDR 9449/2006 and on the extremely-resistant Praha 131 (XDR) strains. All derivatives exhibited a significant activity with minimum inhibitory concentrations (MICs) in the low micromolar range. Eight salicylanilide carbamates and two salicylanilide esters exhibited an excellent in vitro activity on M. abscessus with MICs from 0.2 to 2.1 μM, thus being more effective than ciprofloxacin and gentamicin. This finding is potentially promising, particularly, as M. abscessus is a threateningly chemotherapy-resistant species. M. tuberculosis H37Rv was inhibited with MICs from 0.2 μM, and eleven compounds have lower MICs than isoniazid. Salicylanilide esters and carbamates were found that they were effective also on MDR and XDR M. tuberculosis strains with MICs ≥1.0 μM. The in vitro cytotoxicity (IC50) was also determined on human MonoMac-6 cells, and selectivity index (SI) of the compounds was established. In general, salicylanilide derivatives substituted by halogens on both salicyl and aniline rings showed better activity, than 4-benzoylaniline derivatives. The ester or carbamate bond formation of parent salicylanilides mostly retained or improved antimycobacterial potency with moderate selectivity.

Abstract
New pyridopyrimidine derivatives were defined using a novel HTS in silico docking method (FRIGATE). The target protein was a dUTPase enzyme (EC 3.6.1.23; Rv2697) which plays a key role in nucleotide biosynthesis of Mycobacterium tuberculosis (Mtb). Top hit molecules were assayed in vitro for their antimycobacterial effect on Mtb H37Rv culture. In order to enhance the cellular uptake rate, the TB820 compound was conjugated to a peptid-based carrier and a nanoparticle type delivery system (polylactide-co-glycolide, PLGA) was applied. The conjugate had relevance to in vitro antitubercular activity with low in vitro and in vivo toxicity. In a Mtb H37Rv infected guinea pig model the in vivo efficacy of orally administrated PLGA encapsulated compound was proven: animals maintained a constant weight gain and no external clinical signs of tuberculosis were observed. All tissue homogenates from lung, liver and kidney were found negative for Mtb, and diagnostic autopsy showed that no significant malformations on the tissues occurred.

Abstract
Hypotonia in the neonatal period and early infancy is a common clinical finding. It can be caused by various heterogeneous disorders of different origin which might lead to diagnostic difficulties. Disorders of the neuromuscular junction, such as congenital myasthenic syndromes and neonatal transient myasthenia gravis are among the aetiologies. We report on a case of congenital myasthenia caused by mutation in the long cytoplasmic loop of the epsilon subunit of the acetylcholine receptor and a neonate of a myasthenic mother diagnosed with transient myasthenia gravis.

Abstract
PURPOSE Primary prevention by periconceptional folic acid supplementation can significantly reduce the risk of neural tube defects. EUROCAT, the European network of population-based registries for the epidemiologic surveillance of congenital anomalies, lacks sufficient data on the birth prevalence of neural tube defects in Hungary before and after the promotion of primary prevention by folic acid. Our aims were to compare the birth prevalence of neural tube defects (myelomeningocele, anencephaly and encephalocele) over two 12-year periods in South-Eastern Hungary. Further aims were to compare our data to those ones in other areas in Europe. METHODS Data were collected from the databases of the Department of Hungarian Congenital Abnormality Registry. The total and live birth prevalence rate of neural tube defects were calculated and compared over 1980-1991 and 1994-2005. In addition, the trends in the total birth prevalence, the number of live births and terminations for and stillbirths with neural tube defects were analysed throughout the period of 1994-2005. RESULTS A significant decline was found in the total and live birth prevalence of myelomeningocele, anencephaly and encephalocele over 1994-2005 compared to the period of 1980-1991. The total birth prevalence of neural tube defects, however, showed a trend of increase after 1994, with declining number of live births and increasing number of terminations for neural tube defects. CONCLUSION Public health measures are warranted in order to replace termination of pregnancy with primary prevention in South-Eastern Hungary.

Abstract
The spectrum of lissencephaly ranges from absent (agyria) or decreased (pachygyria) convolutions to less severe malformation known as subcortical band heterotopia. Mutations involving LIS1 and TUBA1A result in the classic form of lissencephaly, whereas mutations of the DCX gene cause lissencephaly in males and subcortical band heterotopia in females. This report describes the clinical manifestations and imaging and genetic findings in 2 boys with lissencephaly and a girl with subcortical band heterotopia. An ovel mutation (c.83_84delAT, p.Tyr28Phefs*31) was identified in LIS1 in 1 of the boys with lissencephaly and another novel mutation (c.200delG, p.Ile68Leufs*87) was found in DCX in the girl with subcortical band heterotopia. The mutations appeared in the first half of the genes and are predicted to result in truncated proteins. A mutation was found in the TUBA1A gene (c.1205G>A, p.Arg402His) in the other boy. This mutation affects the folding of tubulin heterodimers, changing the interactions with proteins that bind microtubules.

Abstract
This study examined the stability of coparenting and its link to child temperament including 88 families with a firstborn toddler (child 1) that were expecting their second baby (child 2) at T1 (in the last trimester of the second pregnancy). Parents reported on the quality of the coparenting relationship and the temperament of both children. Coparental cooperation was observed at T1 with child 1 and at T3 (when child 2 was 1 year old) with child 1 and 2 in triadic and tetradic contexts. Results show that (a) parent-reported coparenting with child 1 was highly stable; however, this stability was moderated by the difficult temperament of child 2; (b) coparenting with child 1 and child 2 on the basis of parent reports was highly correlated longitudinally and concurrently, although longitudinal links were moderated by the difficult temperament of child 2; and (c) cooperative coparenting observed during triadic interaction at T1 was not linked to cooperation observed when four family members interacted at T3. The study presented here provides further evidence of the plasticity of coparenting in young families and that child temperament plays an important role in shaping the coparenting relationships.

Abstract
Mycobacterium tuberculosis is a successful pathogen, and it can survive in infected macrophages in dormant phase for years and decades. The therapy of tuberculosis takes at least six months, and the slow-growing bacterium is resistant to many antibiotics. The development of novel antimicrobials to counter the emergence of bacteria resistant to current therapies is urgently needed. In silico docking methods and structure-based drug design are useful bioinformatics tools for identifying new agents. A docking experiment to M. tuberculosis dUTPase enzyme, which plays a key role in the bacterial metabolism, has resulted in 10 new antitubercular drug candidates. The uptake of antituberculars by infected macrophages is limited by extracellular diffusion. The optimization of the cellular uptake by drug delivery systems can decrease the used dosages and the length of the therapy, and it can also enhance the bioavailability of the drug molecule. In this study, improved in vitro efficacy was achieved by attaching the TB5 antitubercular drug candidate to peptide carriers. As drug delivery components, (i) an antimicrobial granulysin peptide and (ii) a receptor specific tuftsin peptide were used. An efficient synthetic approach was developed to conjugate the in silico identified TB5 coumarone derivative to the carrier peptides. The compounds were effective on M. tuberculosis H37Rv culture in vitro; the chemical linkage did not affect the antimycobacterial activity. Here, we show that the OT20 tuftsin and GranF2 granulysin peptide conjugates have dramatically enhanced uptake into human MonoMac6 cells. The TB5-OT20 tuftsin conjugate exhibited significant antimycobacterial activity on M. tuberculosis H37Rv infected MonoMac6 cells and inhibited intracellular bacteria.

Abstract
A retrospective population based survey of patients born with holoprosencephaly in South-Eastern Hungary between July 1, 1992 and June 30, 2006 was performed. All live birth cases with craniofacial and non-craniofacial abnormalities were included in the study. A total of 9 patients (5 boys and 4 girls) were found with holoprosencephaly among 185 486 live births, which correspond to a birth prevalence of 0.49 per 10,000 live births (95% confidence interval [CI]: 0.17-0.80). These figures were similar to those ones found in New York State and several European regions. In our series one newborn had trisomy 13. Eight patients did not have chromosomal abnormalities on routine testing, 4 of them had craniofacial abnormalities only and another 4 showed non-craniofacial anomalies as well. Three patients died in the neonatal period and another one in childhood. Patients surviving the neonatal period had intellectual and motor handicap, and epilepsy.

Abstract
Data regarding the epidemiology of callosal anomalies are contradictory. We performed a population-based retrospective survey to study the birth prevalence and clinical features of agenesis/hypoplasia of the corpus callosum and accompanying central nervous system and somatic abnormalities in southeastern Hungary between July 1, 1992 and June 30, 2006. Among 185,486 live births, 38 patients (26 boys and 12 girls) manifested agenesis/hypoplasia of the corpus callosum, corresponding to a prevalence of 2.05 per 10,000 live births (95% confidence interval, 1.4-2.7). Callosal anomalies were isolated in 18 patients, and were associated with other central nervous system malformations in five children. Both central nervous system and noncentral nervous system abnormalities were evident in seven patients, whereas callosal dysgenesis was accompanied only by somatic anomalies in eight children. Five of 18 patients with isolated agenesis/hypoplasia of the corpus callosum remained asymptomatic. Developmental delay, intellectual disability, or epilepsy occurred in all patients, except one, when callosal anomalies were combined with other brain or somatic abnormalities. Five patients with multiplex malformations died. Callosal anomalies form a clinically significant and relatively frequent group of central nervous system malformations.

Abstract
The epidemiology and clinical spectrum of schizencephaly in south-eastern Hungary have been surveyed in a retrospective population-based study. A total of 10 patients (6 boys and 4 girls) were found with schizencephaly among 185 486 live births in a period of 14 years (July 1, 1992 to June 30, 2006), which means a birth prevalence of 0.54 per 10 000 (95% confidence interval [CI]: 0.20-0.87). The schizencephaly was unilateral in 7 cases (with closed lips in 5 and open lips in 2 patients) and bilateral in 3 children (with closed lips in 2 and open lips in 1). The septum pellucidum was absent in 5 cases; however, optic nerve hypoplasia was not found in these patients. Delayed development and intellectual disability were observed in all patients, except 2 with unilateral closed lip schizencephaly. Epilepsy was diagnosed in 3 patients (2 with unilateral and 1 with bilateral schizencephaly).

Abstract
AIM To describe the population-based epidemiological characteristics and clinical features of primary microcephaly in Hungary. METHODS A retrospective survey of patients born with microcephaly in a region (Dél-Alföld - South Great Plain) in Hungary between July 1, 1992 and June 30, 2006 was performed. Patients with microcephaly and without any environmental or obstetric risk factors and/or dysmorphism (primary microcephaly) were included in the study. The birth prevalence of primary microcephaly per 10,000 live births was calculated. RESULTS Ten patients (8 girls and 2 boys) were found with primary microcephaly among 185,486 live births, which corresponds to a birth prevalence of 0.54 per 10,000 live births (95% confidence interval: 0.20-0.87). Developmental delay and intellectual disability were the main clinical features. Dyskinesia was seen in one and epilepsy was diagnosed in two patients. The MRI revealed simplified gyral pattern in all patients. CONCLUSION Primary microcephaly is a very rare brain malformation, although the birth prevalence found in this survey is slightly higher than the few figures published earlier. As more and more genes and mutations responsible for primary microcephaly are discovered, the ascertainment of these rare cases is mandatory to provide the parents with genetic counselling.

Abstract
We describe 3 patients with bilateral operculum syndrome. They presented with various degrees of suprabulbar (pseudobulbar) signs in addition to delay in cognitive, motor, and speech development in 2 children and developmental language disorder in the third one. A patient with schizencephaly in the left perisylvian area and contralateral polymicrogyria had spastic hemiparesis on the right side, whereas another patient showed bilateral underdevelopment of the opercula in association with axial hypotonia and spastic diplegia. Both of them had epileptiform discharges on the electroencephalogram without clinical manifestations of seizures. The magnetic resonance imaging of the third child with developmental language disorder was normal; however, his electroencephalogram showed frequent bilateral subclinical centrotemporal epileptiform discharges, probably responsible for the speech delay. Structural or functional involvement of the opercula bilaterally was a common finding in all the 3 patients and they had symptoms similar to those described in the developmental type of Foix-Chavany-Marie and Worster-Drought syndromes.

Abstract
Primary Raynaud's disease is generally a disease of younger females; however, there are cases where symptoms present over the age of 40. These cases are described as late onset. In our current prospective study we compared the characteristics of early and late onset types of primary Raynaud's in 127 patients. In addition to the collection of medical records, we performed capillary-microscopy and hand perfusion scintigraphy using Tc-99 m DTPA to evaluate the microcirculation of each patient's fingers. Regarding the spectrum of the capillary-microscopic findings, we did not find any significant difference between the early and late onset forms. However, in hand perfusion examinations done using Tc-99 m DTPA, we measured a significantly lower finger/palm ratio (FPR) in the early onset group of patients. We also observed a correlation between the duration of the disease and the FPR, as well as between the age and FPR. Longer disease duration resulted in a significantly lower FPR. On the basis of our results, we believe that late onset Raynaud's should be treated as a separate entity. Due to its different characteristics found on examination and follow-up of our patients, functional hand perfusion examination should be recommended independently of the age-related characteristics of the disease.

Abstract
Two regions of rpoB associated with rifampin resistance were sequenced in 29 rifampin-resistant (determined by the proportion method) isolates of Mycobacterium tuberculosis obtained from patients from three counties in Hungary. Of the 29 resistant strains, 27 had a mutation in either the 81-bp region (26 strains) or the N-terminal region (1 strain), while the other 2 strains had no mutations in either region. The locations and frequencies of the mutations differed from those previously reported. The most common mutation in this study, D516V, was found in 38% of the Hungarian strains, a frequency 2 to 10 times higher than that found in studies from other countries. These same 29 isolates were also evaluated with the Inno-LiPA Rif. TB test (LiPA), a reverse hybridization assay for the rapid detection of rifampin resistance. Although LiPA detected the presence of an rpoB mutation in 26 of the resistant isolates, the type of mutation could not be determined in 4 isolates because the mutations present were not among those included on the LiPA strip. In addition, a silent mutation in one of the rifampin-susceptible control strains was interpreted as rifampin resistant by LiPA. These findings demonstrate the importance of validating this rapid molecular test by comparison with DNA sequence results in each geographic location before incorporating the test into routine diagnostic work.
