Cryopreservation has numerous deleterious effects on sperm structure and function, which can be reduced by adding seminal plasma (SP), either autologous or heterologous. The objective was to determine effects of adding boar SP to the freezing extender on sperm quality, tyrosine phosphorylation and fertilizing ability of frozen-thawed ram sperm. Semen was collected from eight Small-tail Han rams and extended in a glucose-egg yolk buffer supplemented with 0, 20, 40, or 60% porcine SP (from Large white boars)...

Injurious pecking (IP) remains one of the major welfare challenges in housing of laying hens worldwide due to the negative consequences it inflicts on animal welfare and economy. One potential solution to reduce IP is the use of dark brooders as the primary heat source during rearing. The objective was to investigate effects of rearing layer chicks with different management strategies and size allowances of dark brooders on IP and production-related traits during rear and lay. Groups of 100 to 103 Isa Warren chicks were reared either with one of 4 brooder types (n = 4 per treatment) or with whole-house heating (control: n = 6)...

The association between exposure to general anesthesia and dementia risk has been inconsistently reported across epidemiological studies. To better understand the association, we conducted a meta-analysis of epidemiological studies. PubMed and Embase were searched through April 2017. Random-effects models were used to pool association estimates. We further evaluated potential dose-response relationship. Based on literature search, seven prospective/cohort studies, 11 case-control studies, and a pooled analysis of six case-control studies were identified...

Ring fixation is a powerful tool in the treatment of bone defects. The ability to create high-quality, biologically normal new bone of even massive proportions using distraction osteogenesis is a major reason for its success. In addition, ring fixation provides the ability to limit the risk of deep infection, improves flexibility in limb length control and alignment, and increases soft tissue coverage options. The drawbacks of ring fixation include long frame times, pin problems, risk of joint contractures, and difficult usage in areas with a large soft tissue envelope such as the thigh...

REVIEW
Kim Van Orden, Charlene Deming
Late life suicide prevention differs from suicide prevention for other age groups: first, the number of older adults worldwide is on the rise; second, late-life suicide receives much less attention in all societal spheres, from the media, to federal funding agencies, to healthcare initiatives. Recent findings indicate an association between internalized ageist stereotypes and reduced will to live. Recent research also addresses the role of cognitive control as a contributor to risk and as an intervention target (e...

Globally, 32.4 million individuals are blind and 191 million have moderate or severe visual impairment (MSVI); 80% of cases of blindness and MSVI are avoidable. However, great efforts are needed to tackle blindness and MSVI, as eye care in most places is delivered in isolation from and without significant integration with general health sectors. Success stories, including control of vitamin A deficiency, onchocerciasis, and trachoma, showed that global partnerships, multisectoral collaboration, public-private partnerships, corporate philanthropy, support from nongovernmental organizations-both local and international-and governments are responsible for the success of these programs...

BACKGROUND: To examine psychological health and perceived social support in patients with chronic edema (CE). METHODS AND RESULTS: A random sample of 107 patients with CE was group matched for age and gender with 102 community controls. The cases had swelling of the arm (38%) and leg (61%) and midline swelling (14%). Cases were more likely to be single or divorced/separated (p = 0.041) and have reduced mobility (p < 0.001). They had significantly poorer overall health related quality of life (HRQoL), in particular physical functioning (p = 0...

BACKGROUND: Fresh osteochondral allografts (OCAs) are limited in availability. The Missouri Osteochondral Allograft Preservation System (MOPS) has been reported to effectively preserve OCAs twice as long as current tissue bank protocols in preclinical studies. HYPOTHESIS: The viable chondrocyte density (VCD) in OCAs preserved for up to 70 days using the MOPS will not be significantly different from day 0, and the VCD in MOPS-preserved OCAs will be significantly higher than for standard tissue bank preservation...

We study how intrinsic parameters of CNT samples affect the properties of macroscopic CNT fibers with optimized structure. We measure CNT diameter, number of walls, aspect ratio, graphitic character, and purity (residual catalyst and non-CNT carbon) in samples from 19 suppliers; we process the highest quality CNT samples into aligned, densely packed fibers, by using an established wet-spinning solution process. We find that fiber properties are mainly controlled by CNT aspect ratio and that sample purity is important for effective spinning...

DNA damage is constantly produced by both endogenous and exogenous factors; DNA lesions then trigger the so-called DNA damaged response (DDR). This is a highly synchronized pathway that involves recognition, signaling and repair of the damage. Failure to eliminate DNA lesions is associated with genome instability, a driving force in tumorigenesis. Proteins carry out the vast majority of cellular functions and thus proteome quality control (PQC) is critical for the maintenance of cellular functionality. PQC is assured by the proteostasis network (PN), which under conditions of proteome instability address the triage decision of protein fold, hold, or degrade...
