BACKGROUND: Kinematic multi-segment foot models have been increasingly used to study foot function. The addition of kinetics to these models may enhance their utility; however, this been hindered by limitations in measuring ground reaction forces (GRFs) under individual foot segments. PURPOSE: To determine the accuracy of partitioning segment GRFs from a single force platform on foot joint kinetics. METHODS: Two potential partitioning methods were applied to a previously published three-segment kinetic foot model...

Diameter deviation or follicle selection during a follicular wave begins with continuous growth rate of F1 (dominant or selected follicle; DF) and decreasing growth rate of F2 (largest subordinate). Intraovarian patterns based on presence or absence of the DF and CL are DF-CL, DF, CL, and devoid (neither DF nor CL). The DF and CL relationships in a pair of ovaries are ipsilateral (DF-CL pattern and devoid pattern) and contralateral (DF pattern and CL pattern). The effects of patterns and relationships on F1, F2, and FSH during deviation were determined in 21 mares...

Bovine tuberculosis (bTB) is a common disease of cattle and wildlife, with economic repercussions and implications for animal and human health. The surveillance of bTB in wildlife is particularly important, to shed light on the epidemiological role of wild species and for the adaptation of control measures. In France, a bTB surveillance system for free-ranging wildlife, the Sylvatub system, was launched in 2011 on wild boars, red deer, roe deer and badgers. It relies on active and passive surveillance activities, constrained by practical difficulties, such as the accessibility of wild animals, and regulatory rules for the trapping of badgers, for example...

BACKGROUND: Acne is very common skin condition. Most patients with acne will have a degree of scarring as a result of their acne. In patients with darker skin color the scarring can be further complicated by hyperpigmentation. Several treatment options can be used to improve acne scarring, however the problem of post acne hyperpigmentation is not often addressed. This study especially focus on the treatment of pigmented post acne scarring using skin microneedling. AIMS: The primary objective is to assess the improvement of pigmentation of acne scarring in patients with dark skin using microneedling...

AIM: to develop the methodology of early primary vitrectomy for aggressive posterior retinopathy of prematurity. MATERIAL AND METHODS: The study included 10 preterm infants (20 eyes; gestational term - 26-30 weeks, post-conceptual age - 34-39 weeks) with severe forms of aggressive posterior retinopathy of prematurity (AP-ROP). All patients underwent a complex ophthalmic examination. Their results were compared with retrospective data of earlier treated AP-ROP patients (10 preterm infants, 20 eyes), in whom laser photocoagulation (LC) was done first (gestational period at the time of LC ranged from 26 to 30 weeks, post-conceptual age - from 34 to 39 weeks)...

Complications and the frequency of their occurrence as the criteria of eye preservation after brachytherapy (BT) are presented in literature with inconsistencies due to the assessment being done after varied follow-up periods (1 month to 5-10 years). The evaluation of complications occurring after applying radioiodine can be found in literature. The complications after BT beta particle emitting ophthalmic applicators are seldom discussed in articles. PURPOSE: to examine the frequency of complications, the characteristics of their development after choroidal melanoma (CM) brachytherapy with ruthenium ophthalmic applicators (OA) during long-term follow-up and determine the possibility of their prevention...

As virtual reality expands in popularity, an increasingly diverse audience is gaining exposure to immersive virtual environments (IVEs). A significant body of research has demonstrated how perception and action work in such environments, but most of this work has been done studying adults. Less is known about how physical and cognitive development affect perception and action in IVEs, particularly as applied to preteen and teenage children. Accordingly, in the current study we assess how preteens (children aged 8-12 years) and teenagers (children aged 15-18 years) respond to mismatches between their motor behavior and the visual information presented by an IVE...

Electric field induced micro/nano patterns in thin polymer film, sometimes referred as electrohydrodynamic patterning, is a promising technique to fabricate micro/nano structures. Extensive attentions have been attracted due to its advantages in micro contact (easy demolding) and low cost. Although considerable work has been done on this technique, including both experimental and theoretical ones, there still appears a requirement for understanding the mechanism of electrohydrodynamic patterning. Thus we systematically studied the effect of different parameters on electrohydrodynamic patterning with a numerical phase field model...

Morgagni is considered the father of pathological anatomy. He died in 1771, 89 years old, and was buried in Saint Maxim church in Padua, where his wife and five of his 15 children were already buried. In 2011, an anthropological analysis confirmed that one of the skulls belonged to the oldest individuals among those found in Morgagni's tomb. A genetic analysis proved a kinship between this skull and the fragments of young individuals (one male and two females), supporting the hypothesis that they were Morgagni and his children...

An unprecedented number of medical students and residents express the desire to participate in global health work during their training and beyond. Preparing learners for work in underserved settings makes it more likely that they will continue to work in areas of need. Training programs that focus on global health have been criticized as there is ample work to be done in the US, and often global health work becomes learner-centric, which is difficult to maintain and potentially burdensome and harmful to the host site...

Congenital heart defects (CHDs) are the most common birth defects in neonatal life. CHDs could be presented as isolated defects or associated with developmental delay (DD) and/or other congenital malformations. A small proportion of cardiac defects are caused by chromosomal abnormalities or single gene defects; however, in a large proportion of cases no genetic diagnosis could be achieved by clinical examination and conventional genetic analysis. The development of genome wide array-Comparative Genomic Hybridization technique (array-CGH) allowed for the detection of cryptic chromosomal imbalances and pathogenic copy number variants (CNVs) not detected by conventional techniques...
