Genetic correlations between 29 wool production and quality traits and 14 whole carcass measures and carcass component traits were estimated from the Information Nucleus of 8 flocks managed across a range of Australian sheep production environments and genetically linked. Wool data were from over 5,000 Merino progeny born over 5 yr, whereas carcass data were from over 1,200 wether progeny of over 176 sires, slaughtered at about 21 kg carcass weight, on average. Wool traits included yearling and adult records for wool weight, fiber diameter, fiber diameter variation, staple strength, scoured color, and visual scores for breech and body wrinkle...

Genetic correlations between 29 wool production and quality traits and live weight and ultrasound fat depth (FAT) and eye muscle depth (EMD) traits were estimated from the Information Nucleus (IN). The IN comprised 8 genetically linked flocks managed across a range of Australian sheep production environments. The data were from a maximum of 9,135 progeny born over 5 yr from 184 Merino sires and 4,614 Merino dams. The wool traits included records for yearling and adult fleece weight, fiber diameter (FD), staple length (SL), fiber diameter CV (FDCV), scoured color, and visual scores for breech and body wrinkle...

BACKGROUND: Breech presentation is a leading cause of cesarean delivery. The use of neuraxial anesthesia increases the success rate of external cephalic version procedures for breech presentation and reduces cesarean delivery rates for fetal malpresentation. Meta-analysis suggests that higher-dose neuraxial techniques increase external cephalic version success to a greater extent than lower-dose techniques, but no randomized study has evaluated the dose-response effect. We hypothesized that increasing the intrathecal bupivacaine dose would be associated with increased external cephalic version success...

The essential role of ultrasound examinations in diagnosis and treatment of developmental dysplasia of the hip (DDH) is widely accepted while the weighting and correlation of protective factors and perinatal risk for DDH still give rise to debate. Our aim was to investigate the impact of single and twofold combined risk and protective factors on the newborns' hip maturity, assessed with the Graf ultrasound method. Therefore, data sets of 11,820 universally screened newborns were analyzed. Univariate and logistic regression analyses were performed to correlate risk and protective factors with mature or immature but appropriate for age and pathologic hip types...

INTRODUCTION: Recent research has demonstrated that the media presentation of childbirth is highly medicalized, often portraying birth as risky and dramatic. Media representation of breech presentation and birth is unexplored in this context. This study aimed to explore the content and tone of news media reports relating to breech presentation and breech birth. METHODS: Google alerts were created using the terms breech and breech birth in online English-language news sites over a 3-year period from January 1, 2013, to December 31, 2015...

When a firearm is discharged, the individual marks of the breech face and firing pin are imprinted onto the primer of the cartridge case. These individual marks are reproducible between shots; however, over a large number of consecutive shots, it has been observed that minute changes in these individual marks may occur. Changes in individual marks may affect an examiner in their ability to identify or eliminate and may change the magnitude of a likelihood ratio, depending on the system used by the laboratory, but the effect that these changes have on the Integrated Ballistic Identification System (IBIS(®)) is largely unknown...

INTRODUCTION: Although caesarean section rates have been increasing over the years in both public and private sectors in Hong Kong, there has been a paucity of formal surveys on local trends in such rates. This study aimed to examine the trends in caesarean section rates over a 20-year period at a public regional obstetric unit in Hong Kong using the Robson's Ten-group Classification System. METHODS: All deliveries in a single obstetric unit during a 20-year period (1995-2014) were classified into 10 subgroups according to the Robson's classification...

Using a Gifford-McMahon cycle cryocooler based refrigeration system, a single barrel hydrogen pellet injection (SPINS-IND) system is indigenously developed at Institute for Plasma Research, India. The injector is based on a pipe gun concept, where a pellet formed in situ in the gun barrel is accelerated to high speed using high pressure light propellant gas. The pellet size is decided by considering the Greenwald density limit and its speed is decided by considering a neutral gas shielding model based scaling law...

In the last decades the exponential increase in frequency of Caesarean sections is being observed. At the same time, there is growing amount of epidemiologic data showing higher lifetime risk of incidence of several diseases in offspring who do not experience natural labour. These findings lead to investigation of mechanisms which are responsible for maladaptation of several organ systems. Authors of this article describe these mechanisms, focusing especially on epigenetic programming, production of microbiome and positive effect of peripartal stress on successful beginning of extrauterine life...

INTRODUCTION: The most common fractures during vaginal delivery occur in the clavicle, humerus, and femur. Cesarean section reduces the chances of a child having a birth injury. However, in some difficult extractions, long bone fractures may occur. Cesarean section further reduces the incidence of birth injuries, especially in a breech delivery. Maneuvers employed during cesarean section, energetic traction, improper uterine incisions, and contracted uterus may cause these injuries. In the medical literature, there are few articles highlighting the occurrence of long bone fractures during cesarean section...

This article considers the reception and representation of advanced military technology in late nineteenth- and early twentieth-century Britain. It argues that technologies such as the breech-loading rifle and the machine gun existed in an ambiguous relationship with contemporary ideas about martial masculinities and in many cases served to fuel anxieties about the physical prowess of the British soldier. In turn, these anxieties encouraged a preoccupation in both military and popular domains with that most visceral of weapons, the bayonet, an obsession which was to have profound consequences for British military thinking at the dawn of the First World War...

We report the case of a 36-year old man who underwent elective posterior lumbar spinal fusion after presenting with bilateral leg pain with associated back pain. He had undergone a L5/S1 discectomy in 2001, which provided good symptomatic relief. On this admission, he underwent elective L4-S1 posterolateral fusion and bilateral L4/5 and L5/S1 decompression. Intra-operatively a pedicle screw had to be re-inserted after fluoroscopy confirmed a lateral breech. The patient had no major postoperative complications until the sixth day when the patient re-presented with acute leg pain and weakness...

BACKGROUND: Inconsistent evidence of a higher risk of adverse perinatal outcomes during off-hours compared to office hours necessitated a search for clear evidence of an association between time of birth and adverse perinatal outcomes. METHODS: A cross-sectional study conducted at a tertiary referral hospital compared perinatal outcomes across three working shifts over 24 h. A checklist and a questionnaire were used to record parturients' socio-demographic and obstetric characteristics, mode of delivery and perinatal outcomes, including 5th minute Apgar score, and early neonatal mortality...
