Anthony D Fox, Jesper Madsen
Wild geese wintering in western Europe were declining by the 1930s probably due to loss of natural habitat and over exploitation through hunting, although the causes will never be known. Refuge provision and hunting restrictions from the 1950s enabled numbers to recover. Improved monitoring systems enabled the description of progressive increases and extensions of wintering range since that time, especially amongst those goose populations that increasingly exploited agricultural landscapes. This introductory article sets the scene for the special issue on the increasing interactions and conflicts created by recent increases in the range and abundance of wild geese throughout the northern hemisphere, especially with regard to agricultural damage, but including issues associated with air flight safety, human and animal health, ecosystem effects and conflicts with other biodiversity objectives...

Between the early 1900s and the 1990s, the greater snow goose Anser caerulescens atlanticus population grew from 3000 individuals to more than 700 000. Because of concerns about Arctic degradation of natural habitats through overgrazing, a working group recommended the stabilization of the population. Declared overabundant in 1998, special management actions were then implemented in Canada and the United States. Meanwhile, a cost-benefit socioeconomic analysis was performed to set a target population size. Discussions aiming towards attaining a common vision were undertaken with stakeholders at multiple levels...

After contact shots to the head biological traces inside firearm barrels can be found. This study was conducted to simulate and to evaluate such staining. Five current handguns of four inch barrel length in the calibre .22 long rifle, 7.65mm Browning, 9mm Luger and .38 special were used to perform 24 contact shots on silicone coated, gelatine filled box models using the triple contrast method. The staining was documented by endoscopy and swabs gathered from both ends of the barrel were analysed by quantitative PCR...

Acupuncture Anesthesia originated from the pain relief and pain prevention theory in acupuncture and moxibustion. This technique is a new exploration of anesthesiology and an original achievement of China, representing a landmark combination of Traditional Chinese Medicine (TCM) and Western medicine. Acupuncture Anesthesia was initiated in 1958, and, reflecting the historical background of China after the 1960s, the use of this technique widely spread throughout the country. Reaching other countries after 1971, Acupuncture Anesthesia made a significant impact, drawing attention from medical academia worldwide...

BACKGROUND: Heart failure is associated with exacerbated symptoms such as dyspnea and edema and results in frequent hospitalization and a poor quality of life. With the adoption of a comprehensive nursing care and follow-up program, patients with heart failure may exhibit improvements in their self-care capabilities and their hospitalizations may be reduced. OBJECTIVE: The purpose of this study was to examine the effect of a nursing care and follow-up program for patients with heart failure on self-care, quality of life, and rehospitalization...

Articular cartilage is a specialized tissue that lines the surface of joints. Injuries to articular cartilage pose challenges due to poor healing potential. Focal cartilage defects are typically the result of high impact or repetitive loads to the articular surface. They tend to occur in the younger, active population and have been shown to cause swelling, pain, and joint dysfunction. Although the natural history of these lesions has never been definitively elucidated in the literature, clinical experience suggests that if left untreated, these lesions will demonstrate an inability to heal and may lead to prolonged increased articular peak stresses, which in turn may lead to pain and significant limitations in the future...

Tissue-resident memory T (Trm) cells form a heterogeneous population that provides localized protection against pathogens. Here, we identify CD49a as a marker that differentiates CD8(+) Trm cells on a compartmental and functional basis. In human skin epithelia, CD8(+)CD49a(+) Trm cells produced interferon-γ, whereas CD8(+)CD49a(-) Trm cells produced interleukin-17 (IL-17). In addition, CD8(+)CD49a(+) Trm cells from healthy skin rapidly induced the expression of the effector molecules perforin and granzyme B when stimulated with IL-15, thereby promoting a strong cytotoxic response...

BACKGROUND: The concept of free interposition arthroplasty proved successful for small joints of the hand, wrist, and foot, particularly after the use of implants coated with pyrocarbon, which enhanced their tribologic and elastic properties. The present study reports preliminary outcomes of a pyrocarbon-coated interposition shoulder arthroplasty (PISA) implant. METHODS: This was a prospective study of 67 consecutive patients who underwent shoulder PISA at 9 centers...

The capacity and motivation to be social is a key component of the human adaptive behavioral repertoire. Recent research has identified social behaviors remarkably similar to our own in other animals, including empathy, consolation, cooperation, and strategic deception. Moreover, neurobiological studies in humans, nonhuman primates, and rodents have identified shared brain structures (the so-called 'social brain') apparently specialized to mediate such functions. Neuromodulators may regulate social interactions by 'tuning' the social brain, with important implications for treating social impairments...

As a special group of naturally occurring flavonoids, homoisoflavonoids have been discovered as active components of several traditional Chinese medicines for nourishing heart and mind. In this study, twenty homoisoflavonoid analogues, including different substitution groups on rings A and B, as well as heteroaromatic B ring, were synthesized and evaluated for their cardioprotective and neuroprotective activities. In a H2O2-induced H9c2 cardiomyocytes injury assay, nine homoisoflavonoid analogues showed promising activities in the same level as the positive control, diazoxide...

The Virtual Dental Home is a concept of the Pacific Center for Special Care of the Arthur A. Dugoni School of Dentistry in San Francisco. It is designed to improve access to dental care for underserved populations, specifically children and institutionalized adults. This article describes the development and implementation of the Virtual Dental Home, subsequently critiquing the concept. The criteria for a dental home are not met by the program. It is the equivalent of a traditional public oral health prevention and screening program, with the additional dimension of allowing dental hygienists and assistants to place interim glass ionomer restorations in dental cavities...

Experts are increasingly concerned by issues regarding the activity level of DNA stains. A case from our burglary-related casework pointed out the need for experiments regarding the persistence of DNA when more than one person touched a tool handle. We performed short tandem repeat (STR) analyses for three groups of tools: (1) personal and mock owned tools; (2) tools, which were first "owned" by a first user and then handled in a burglary action by a second user; and (3) tools, which were first owned by a first user and then handled in a moderate action...

INTRODUCTION: Tumors localized in the proximal tibial meta-diaphysis often lead to osteoarticular resections. MATERIALS AND METHODS: In this study, we retrospectively reviewed four patients who underwent intercalary tumor resection and reconstruction using an ultra-short stem in the proximal tibial epiphysis, a procedure that to our knowledge has not been reported in literature so far. RESULTS: At the time of operation, the mean patient age was 26...

INTRODUCTION AND HYPOTHESIS: The majority of patients with cystocele undergoing reconstructive surgery have combined defects of pubocervical fascia and uterosacral/cardinal ligament complex. In this regard, the simultaneous correction of both defects is rational. Furthermore, decreasing the use of synthetic materials in pelvic floor surgery is an important goal. The aim was to evaluate the objective and subjective cure rate of a hybrid technique: bilateral sacrospinous fixation using modern monofilament synthetic tape (apical sling) combined with the original technique of subfascial colporrhaphy...

Microglia, the principal resident immune cell in the retina, play constitutive roles in immune surveillance and synapse maintenance, and are also associated with retinal disease, including those occurring in the macula. Perspectives on retinal microglia function have derived largely from rodent models and how these relate to the macula-bearing primate retina is unclear. In this study, we examined microglial distribution and cellular morphology in the adult rhesus macaque retina, and performed comparative characterizations in three retinal locations along the center-to-periphery axis (parafoveal, macular, and the peripheral retina)...

The results of a theoretical study are presented dealing with convective heat and mass transfer in a colloidal suspension through a Hele-Shaw cell heated from below. The numerical analysis, based on a multi-component model, reveals that for a certain range of parameter values the dynamical regimes of travelling waves as well as oscillatory fingering formation are stable. The bifurcation phenomena and nonlinear evolution of spatiotemporal patterns that develop in the colloid suspension are modeled and discussed, paying special attention to the combined effects of gravity sedimentation, thermal diffusion with positive separation ratio and convection...

Articular cartilage is a connective tissue consisting of a specialized extracellular matrix (ECM) that dominates the bulk of its wet and dry weight. Type II collagen and aggrecan are the main ECM proteins in cartilage. However, little attention has been paid to less abundant molecular components, especially minor collagens, including type IV, VI, IX, X, XI, XII, XIII, and XIV, etc. Although accounting for only a small fraction of the mature matrix, these minor collagens not only play essential structural roles in the mechanical properties, organization, and shape of articular cartilage, but also fulfil specific biological functions...

Psychosomatic disorders of the scalp have some special characteristics due to the visibility, possible stigmatization, and amount/patterns of hair. Of practical relevance is trichotillomania, which is now classified as an obsessive-compulsive disorder (OCD). Patients who are obsessed with normal physiological hair loss represent a further psychodermatological challenge. Psychosomatic therapy includes basic psychosomatic care, behavior therapy, or treatment with psychopharmaceuticals.

The worldwide burden of mental disorders is considerable, and on the rise, putting pressure on health care systems. Current reforms aim to improve the efficiency of mental health care systems by increasing service integration in communities and strengthening primary mental health care. In this context, mental health care professionals (MHPs) are increasingly required to work on interdisciplinary teams in a variety of settings. Little is known, however, about the profiles of MHPs in relation to their perceived work role performance...
