Abstract Ornithine transcarbamylase deficiency (OTCD) is a rare X‐linked urea cycle disorder. Maternal OTCD can lead to life‐threatening hyperammonemia if untreated. We aimed to compare the outcomes of maternal OTCD when diagnosis is known prior to pregnancy to when diagnosis is made during pregnancy. We performed a systematic literature review on maternal OTCD using the databases Ovid MEDLINE and PubMed from 1982 through 2018. Studies were included if addressed maternal OTCD signs, symptoms, and...
Abstract Pathogenic variants in polynucleotide kinase 3′‐phosphatase (PNKP) gene have been associated with two distinct clinical presentations: autosomal recessive microcephaly, seizures, and developmental delay (MCSZ; MIM 613402) and ataxia with oculomotor apraxia type 4 (AOA4; MIM 616267). More than 40 patients have been reported so far, and their clinical presentations revealed a continuum phenotypic spectrum ranging from congenital microcephaly and early‐onset intractable seizures, to adult...
Abstract Esophageal atresia (EA) with or without tracheoesophageal fistula (TEF) is a foregut defect that is a major component of the VATER/VACTERL association. The specific diagnostic criteria for the VATER/VACTERL association phenotype have changed over time. The current definition is presence of at least three of the following: Vertebral defects, Anal atresia, Cardiac defects, TE fistula, or Renal and Limb anomalies in the absence of a specific genetic diagnosis. Using the Texas Birth Defect...
Abstract Alveolar capillary dysplasia with misalignment of pulmonary veins (ACDMPV) is a rare lethal lung developmental disease. Affected infants manifest with severe respiratory distress and refractory pulmonary hypertension and uniformly die in the first month of life. Heterozygous point mutations or copy‐number variant deletions involving FOXF1 and/or its upstream lung‐specific enhancer on 16q24.1 have been identified in the vast majority of ACDMPV patients. We have previously described two unrelated...

The hypothalamic neuropeptide RFRP3 can suppress hypothalamic GnRH neuron activation and inhibit gonadotropin release from the anterior pituitary. RFRP3 is also produced locally in the ovary and can inhibit steroidogenesis and follicle development in many vertebrates. However, almost nothing is known about the presence and regulatory action of RFRP3 in gonads of any carnivore species. Such knowledge is important for developing captive breeding programs for endangered carnivores and for inhibiting...
The family Pyxicephalidae including two subfamilies (Cacosterninae and Pyxicephalinae) is an ecologically important group of frogs distributed in sub-Saharan Africa. However, its phylogenetic position among the Anura has remained uncertain. The present study determined the complete mitochondrial genome sequence of Pyxicephalus adspersus, the first representative mitochondrial genome from the Pyxicephalinae, and reconstructed the phylogenetic relationships within Ranoidae using 10 mitochondrial protein-coding...
This article compares the differences in eye movements between orienteers of different skill levels on map information searches and explores the visual search patterns of orienteers during precise map reading so as to explore the cognitive characteristics of orienteers’ visual search. We recruited 44 orienteers at different skill levels (experts, advanced beginners, and novices), and recorded their behavioral responses and eye movement data when reading maps of different complexities. We found that...
Background Biopesticides based on strains of the bacterium Bacillus thuringiensis (Bt) are used globally for effective and environmentally friendly pest control. The most serious threat to the sustainable use of these microbial pesticides is the development of resistance on targeted pests. Populations of Plutella xylostella (diamondback moth) have evolved field resistance to Bt pesticides at diverse locations worldwide. Discovery of novel Bt strains with varied toxin profiles that...
Arbuscular mycorrhiza (AM) is known to be a mutually beneficial plant-fungal symbiosis; however, the effect of mycorrhization is heavily dependent on multiple biotic and abiotic factors. Therefore, for the proper employment of such plant-fungal symbiotic systems in agriculture, a detailed understanding of the molecular basis of the plant developmental response to mycorrhization is needed. The aim of this work was to uncover the physiological and metabolic alterations in pea (Pisum sativum L.) leaves...
Intersex is an intermediate stage of sexual differentiation in insects. Determining intersex morphology and the cause of its production will aid in the understanding of the mechanism of sexual differentiation in insects. In this paper, Wolbachia-infected Trichogramma pretiosum (T. preW+) that shows thelytokous parthenogenesis were used as subjects. In order to determine the causes of the T. preW+ intersex and the influence of parental generation temperature on gradual changes in secondary masculinization...
Watermelon (Citrullus lanatus Thunb.) is considered as a popular and nutritious fruit crop worldwide. Watermelon blood flesh disease caused by Cucumber green mottle mosaic virus (CGMMV) and bacterial fruit blotch caused by Acidovorax citrulli, are two major quarantine diseases of watermelon and result in considerable losses to global watermelon production. In this study, a multiplex reverse-transcription polymerase chain reaction (RT-PCR) method was developed for simultaneous detection of CGMMV and...
A single species of the dicynodontoid dicynodont Dicynodon is currently recognized from the late Permian Usili Formation of Tanzania: Dicynodon huenei Haughton, 1932. Restudy of the known Tanzanian materials of D. huenei demonstrates that they represent two distinct morphotypes, here considered separate taxa. The holotype of D. huenei is not referable to Dicynodon and instead is transferred to the genus Daptocephalus (but retained as a valid species, Daptocephalus huenei comb. nov.). A number of...
Background In the last 20 years, a general picture of the evolutionary relationships between geoemydid turtles (ca. 70 species distributed over the Northern hemisphere) has emerged from the analysis of molecular data. However, there is a paucity of good traditional morphological characters that correlate with the phylogeny, which are essential for the robust integration of fossil and molecular data. Part of this problem might be due to intrinsic limitations of traditional discrete characters. Here,...

An immunoinformatic approach followed by molecular dynamics simulation and systems biology approach has been adopted to predict and validate the potential B and T cell epitopes of Human Herpes Virus Type 1 because of its global burden and virulent nature. These epitopes formed strong interactions and expressed stable nature in the binding grove of human MHC‐I molecule, therefore, may have the ability to provoke the immune system, protecting against the HSV‐1 infection. Abstract The human...
Two PMAP‐37 analogs named PMAP‐37(R13‐I), PMAP‐37(K20/27‐I) were designed to enhance hydrophobicity. These analogs exhibited antibacterial activity in vitro and vivo, of which, PMAP‐37(K20/27‐I) exhibited therapeutic effects, whether in the clinical symptoms, the tissue lesions, or the tissue bacterial load and the survival rate, in mice infected S. aureus ATCC25923 or S. typhimurium SL1344 compared to the PMAP‐37. So, PMAP‐37(K20/27‐I) may be a candidate clinical drug for bacterial infections. ...

Previous research has documented that contour detection and integration may either be affected by local features such as the distances between elements or by high-level cognitive factors such as attention in our visual system. Less is known about how low and high level factors interact to influence contour integration. In this paper, we investigated how attention modulates contour integration through saliency (different element spacing) and topological propert ies (circle or S-shaped) when the state...
