The primary aim of this study was to evaluate the convergent validity of the Motor domain (MOT) of PediaTracTM v3.0, an online developmental tracking instrument based on caregiver reports, with fine and gross motor domains (ASQ-FM and ASQ-GM) of the Ages and Stages Questionnaire (ASQ-3) in infants between 2- and 9 months of age. Participants were caregivers of 571 infants born term or preterm (gestational age <37 weeks) enrolled in a multi-site psychometric study of PediaTracTM . Findings revealed significant correlations between MOT and ASQ-3 scores at 2, 4, 6, and 9 months across time periods, term-preterm status, and biological sex...

Purpose: Retroperitoneal robotic-assisted pyeloplasty (ret-RAP) for ureteropelvic junction obstruction (UPJO) requires a larger retroperitoneal space (RS) to maintain specified distances between robotic (da Vinci) trocars and between trocars and the region of interest. A modified closed technique (MOT) and conventional closed technique (COT) were compared for creating an adequate RS with optical trocars. Methods: RS access in children with UPJO who underwent ret-RAP ( n  = 30) was MOT ( n  = 15) and COT ( n  = 15)...

Multiple object tracking (MOT) involves simultaneous tracking of a certain number of target objects amongst a larger set of objects as they all move unpredictably over time. The prevalent explanation for successful target tracking by humans in MOT involving visually identical objects is based on the Visual Indexing Theory. This assumes that each target is indexed by a pointer using a non-conceptual mechanism to maintain an object's identity even as its properties change over time. Thus, successful tracking requires successful indexing and the absence of identification errors...

We present a cold atomic beam source based on a two-dimensional (2D)+ magneto-optical trap (MOT), capable of generating a continuous cold beam of 87 Rb atoms with a flux up to 4.3 × 109  s-1 , a mean velocity of 10.96(2.20) m/s, and a transverse temperature of 16.90(1.56) µK. Investigating the influence of high cooling laser intensity, we observe a significant population loss of atoms to hyperfine-level dark states. To account for this, we employ a multiple hyperfine level model to calculate the cooling efficiency associated with the population in dark states, subsequently modifying the scattering force...

BACKGROUND: Ewing's sarcoma is a rare malignant entity. Extraosseous Ewing's sarcoma (EES) of the head and neck region is a rare occurrence, and Ewing's sarcoma of the parotid gland is even rarer. To the best of our knowledge, we reported the first case of extraskeletal ES originating from the parotid gland in the Tunisian literature. CASE REPORT: We report a rare case of EES of the parotid gland in a 35-year-old female. She presented with left parotid tumefaction...

Nonsymbiotic phytoglobins (nsHbs) are a diverse superfamily of hemoproteins grouped into three different classes (1, 2, and 3) based on their sequences. Class 1 Hb are expressed under hypoxia, osmotic stress, and/or nitric oxide exposure, while class 2 Hb are induced by cold stress and cytokinins. Both are mainly six-coordinated. The deoxygenated forms of the class 1 and 2 nsHbs from A. thaliana (AtHb1 and AtHb2) are able to reduce nitrite to nitric oxide via a mechanism analogous to other known globins. NsHbs provide a viable pH-dependent pathway for NO generation during severe hypoxia via nitrite reductase-like activity with higher rate constants compared to mammalian globins...

PURPOSE OF REVIEW: In recent years, the xenotransplantation science has advanced tremendously, with significant strides in both preclinical and clinical research. This review intends to describe the latest cutting-edge progress in knowledge and methodologies developed to overcome potential obstacles that may preclude the translation and successful application of clinical xenotransplantation. RECENT FINDINGS: Preclinical studies have demonstrated that it is now possible to extend beyond two years survival of primate recipients of life saving xenografts...

Crop production often faces challenges from plant diseases, and biological control emerges as an effective, environmentally friendly, cost-effective, and sustainable alternative to chemical control. Wheat blast disease caused by fungal pathogen Magnaporthe oryzae Triticum (MoT), is a potential catastrophic threat to global food security. This study aimed to identify potential bacterial isolates from rice and wheat seeds with inhibitory effects against MoT. In dual culture and seedling assays, three bacterial isolates (BTS-3, BTS-4, and BTLK6A) demonstrated effective suppression of MoT growth and reduced wheat blast severity when artificially inoculated at the seedling stage...

BACKGROUND: Acute lung injury (ALI) has garnered significant attention in the field of respiratory and critical care due to its high mortality and morbidity, and limited treatment options. The role of the endothelial barrier in the development of ALI is crucial. Several bacterial pathogenic factors, including the bacteria-derived formyl peptide (fMLP), have been implicated in damaging the endothelial barrier and initiating ALI. However, the mechanism by which fMLP causes ALI remains unclear...

PURPOSE OF REVIEW: Normothermic regional perfusion (NRP) is a novel procurement technique for donation after circulatory death (DCD) in the United States. It was pioneered by cardiothoracic surgery programs and is now being applied to abdominal-only organ donors by abdominal transplant programs. RECENT FINDINGS: Liver and kidney transplantation from thoracoabdominal NRP (TA-NRP) donors in the United States was found to have lower rates of delayed kidney graft function and similar graft and patient survival versus recipients of cardiac super rapid recovery (SRR) DCD donors...

It is estimated that in highly medicalised countries, median life expectancy for most newborns with cystic fibrosis now exceeds 70 years, approaching that of the general population. However, socio-economic disparities between countries continue to have a devastating impact on the prognosis of patients in Eastern Europe, Africa, India and South America. In Morocco, very limited genetic data suggest that the prevalence of this disease is at least of the same order as in Belgium. But as it is not really recognised by the national health system, patients are denied access even to symptomatic treatment...

PURPOSE OF REVIEW: To provide an update regarding the state of thoracoabdominal normothermic regional perfusion (taNRP) when used for thoracic organ recovery. RECENT FINDINGS: taNRP is growing in its utilization for thoracic organ recovery from donation after circulatory death donors, partly because of its cost effectiveness. taNRP has been shown to yield cardiac allograft recipient outcomes similar to those of brain-dead donors. Regarding the use of taNRP to recover donor lungs, United Network for Organ Sharing (UNOS) analysis shows that taNRP recovered lungs are noninferior, and taNRP has been used to consistently recover excellent lungs at high volume centers...

PURPOSE OF REVIEW: While liver transplant for unresectable colorectal cancer liver metastases (CRLM) has been demonstrated to be a promising treatment in selected patients, the typically low MELD score of these patients and lack of exception points may lead to challenges in receiving a deceased donor liver for transplant. RECENT FINDINGS: Several studies have shown improved outcomes in select patients with CRLM who undergo liver transplant, and several trials are ongoing and will conclude in the next several years...

PURPOSE OF REVIEW: The adoption of brain death played a crucial role in the development of organ transplantation, but the concept has become increasingly controversial. This essay will explore the current state of the controversy and its implications for the field. RECENT DEVELOPMENTS: The brain death debate, long limited to the bioethics community, has in recent years burst into the public consciousness following several high-profile cases. This has culminated in the reevaluation of the Uniform Determination of Death Act (UDDA), which is in the process of being updated...

PURPOSE OF REVIEW: The number of patients on the liver transplant waitlist continues to grow and far exceeds the number of livers available for transplantation. Normothermic machine perfusion (NMP) allows for ex-vivo perfusion under physiologic conditions with the potential to significantly increase organ yield and expand the donor pool. RECENT FINDINGS: Several studies have found increased utilization of donation after cardiac death and extended criteria brain-dead donor livers with implementation of NMP, largely due to the ability to perform viability testing during machine perfusion...

BACKGROUND: Oropharyngeal cancer is a global health concern due to its multifaceted nature. Recent molecular studies have linked p16 overexpression, associated with the human papillomavirus, to oropharyngeal cancer and its prognostic implications. MATERIALS AND METHODS: This retrospective study in Western Romania examined 60 patients, categorizing them based on p16 biomarker status: 28 were p16 positive, and 32 were p16 negative. Statistical tests, including Fisher's exact and chi2, were used for analysis...

PURPOSE OF REVIEW: Normothermic regional perfusion (NRP) is a novel procurement technique for donation after circulatory death (DCD) in the United States. It was pioneered by cardiothoracic surgery programs and is now being applied to abdominal-only organ donors by abdominal transplant programs. Multiple technical approaches can be used for abdominal-only NRP DCD donors and this review describes these techniques. RECENT FINDINGS: NRP has been associated with higher utilization of organs, particularly liver and heart grafts, from DCD donors and with better recipient outcomes...

MOTS-c, a mitochondrial-derived peptide, acts as a systemic hormone and MOTS-c level is inversely correlated with markers of obesity. Obesity is a risk factor for male reproductive physiology and is expressed as an important cause of infertility. In this study, we aimed to determine the effects of MOTS-c, which has been proven in the hypothalamus and testicles, on the actors involved in the reproductive axis. In the study, 80 male Wistar-Albino rats were divided into two main groups, obese and non-obese (n = 40)...

The flagellar motor is a powerful macromolecular machine used to propel bacteria through various environments. We determined that flagellar motility of the alpha-proteobacterium Sinorhizobium meliloti is nearly abolished in the absence of the transcriptional regulator LdtR, known to influence peptidoglycan remodeling and stress response. LdtR does not regulate motility gene transcription. Remarkably, the motility defects of the ΔldtR mutant can be restored by secondary mutations in the motility gene motA or a previously uncharacterized gene in the flagellar regulon, which we named motS...
