Cryopreservation of gametes and embryos of non-domestic species.

Many species of mammals are threatened or endangered. Methods of assisted reproduction that are being used with increasing frequency to produce offspring of domestic animals and humans are often viewed as offering innovative ways to reproduce non-domestic species as well. Uncounted millions of live young of domestic or laboratory species have been produced from gametes and embryos stored at -70 degrees C or below, sometimes for as long as 25 to 35 yrs. Such methods of cryopreservation are now being applied with increasing frequency and urgency to preserve gametes and embryos of non-domestic and threatened species to establish "genome resource banks" or "frozen zoos." But levels of success to produce live young from such cryopreserved gametes or embryos vary considerably from species to species, as well as from individual to individual. It is sometimes thought that differences among species in fundamental characteristics of their gametes may determine the efficacy of cryopreservation and the production of live young. However, it may not be that ineffective cryopreservation is responsible for low success rates. Rather, the limiting factor may be insufficient information and knowledge of the most basic reproductive biology of such non-domestic species. Even standard methods of cryopreservation may be completely adequate to act as a "temporary" expedient to preserve germplasm of non-domestic species to permit time to acquire a fuller understanding of the biology and behavior of non-domestic species.

Bezoar (Capra aegagrus) is a matriarchal candidate for ancestor of domestic goat (Capra hircus): evidence from the mitochondrial DNA diversity.

The leading hypothesis on the ancestor of domestic goats (Capra hircus) is that it is the wild goat called the bezoar or pasang (Capra aegagrus). To verify this hypothesis, we sequenced and compared the cytochrome b gene of mitochondrial DNA from six domestic goats and bezoar. A further sequence for the markhor was taken from the database. In total we detected 51 nucleotide substitutions among the domestic goats, bezoar and markhor. However, only one specific nucleotide substitution was found between the domestic goats and the bezoar. On the other hand, 43 nucleotide substitutions were specific for the markhor. This result suggested a close relationship between the domestic goats and the bezoar. A neighbor-joining and parsimony phylogenetic tree constructed using the sequences showed that the domestic goats and the bezoar belong to the same cluster, while the markhor showed a distinct cluster separate from that of the domestic/bezoar cluster. This result was confirmed by trees based on the sequence of the mitochondrial displacement loop regions. These results suggest that the strongest candidate for a matriarchal ancestor of domestic goats is the bezoar.

Genotyping of Clostridium perfringens isolated from domestic and exotic ruminants and swine.

Clostridium perfringens types A, B, C, D and E are known to cause severe enteritis/enterotoxaemia and diseases (especially caused by type A) belonging to the gas oedema complex in many species. Samples from the small intestine as well as faeces of domestic and exotic animals suffering from enterotoxaemic signs or having died within days after first occurance of toxaemia were submitted for typing C. perfringens toxovars by multiplex PCR. The following species have been investigated: domestic sheep (Ovis ammon; n = 10), domestic goat (Capra aegagrus hircus; n = 26), Japanese serow (Capricornis sumatraensis; n = 4), lechwe waterbuck (Hydrotragus leche; n = 1), blackbuck (Antilope cervicapra; n = 1), European reindeer (Rangifer tarandus tarandus; n = 4), domestic swine (Sus scrofa; n = 52), and collared peccary (Tayassu albirostris; n = 1). Interestingly, the predominant C. perfringens toxovar in domestic sheep was type A. This toxovar could also be diagnosed in all reindeer, in three Japanese serows, one lechwe waterbuck and most pigs (n = 47), the majority of those being at suckling age. Type D was the most prevalent toxovar (n = 18) in domestic goats, but also types A and E could be identified as pathogens in this species. Type C could only be found in domestic swine (n = 5) and in one case of clostridiosis in a Japanese serow. Two cases of enterotoxaemia in goats, one case in reindeer, and a single case in blackbuck and collared peccary were caused by C. perfringens type E. Genotyping of C. perfringens is recommended before starting vaccination programmes as it could be shown, that the importance of specific toxovars has been underestimated in specific species and/or age groups.

Can screening for domestic violence be introduced successfully in a sexual health clinic?

BACKGROUND: Domestic violence is reported frequently when Australian women are surveyed and is associated with poorer health outcomes on a variety of measures. Routine screening for domestic violence is a strategy designed to both prevent domestic violence and provide an opportunity for early intervention. METHODS: Following staff consultation and training, a 1-month pilot of routine screening for domestic violence (RSDV) of all female patients was conducted in a large sexual health clinic. RESULTS: Following the evaluation of this pilot, RSDV was introduced in 2003 for all new female patients. Of the 3244 women eligible for screening, 2893 (89%) were screened. Of these, 254 (8.8%) identified domestic violence. CONCLUSIONS: Routine screening for domestic violence is feasible in a sexual health clinic population. High screening rates were achieved and high rates of domestic violence were identified, providing an opportunity for intervention.

Eastern North America as an independent center of plant domestication.

The status of eastern North America as an independent center of plant domestication has recently been called into question by a number of genetic and archaeological studies, which suggest that the region may not have witnessed the independent domestication of local crop plants, but rather may have been on the receiving end of domesticated crop plants introduced from Mexico. Here, I provide a synthesis of the currently available archaeological and genetic evidence from both eastern North America and Mexico regarding the spatial and temporal context of initial domestication of the four plant species identified as potential eastern North American domesticates: marshelder (Iva annua), chenopod (Chenopodium berlandieri), squash (Cucurbita pepo), and sunflower (Helianthus annuus). Genetic and archaeological evidence provides strong support for the independent domestication of all four of these plant species in the eastern United States and reconfirms the region as one of the world's independent centers of domestication.

Attitudes and practices of doctors toward domestic violence victims in South Africa.

Our study intended to ascertain doctors' attitudes and practices toward domestic violence in a sample of 402 doctors randomly chosen for a mail survey from a list of registered medical practitioners in South Africa. We found that the mean number of patients treated for domestic violence per month was 11.4 (SD = 13.4); for White doctors 15.8, African Black 6.2, and for Asian doctors 5.3. The high frequency of domestic violence detected in this sample seems to reflect national surveys on domestic violence. Most doctors believed that they should play a role in prevention and treatment, and their attitudes toward victims of domestic violence were generally sympathetic and supportive. Male doctors and long-serving practitioners tended to have more conservative views of the causes and attitudes of spousal assault and of the doctors' role in prevention. Only 9.7% of the doctors had received any training on domestic violence. Further research is needed to establish the prevalence of domestic violence in women presenting to medical practitioners and to investigate how the problem currently is being addressed.

Lead levels in domestic water supplies and neural tube defects in Glasgow.

OBJECTIVE: To study the association between "pregnancy" prevalence (affected births and terminations) of neural tube defects in postcode districts of Glasgow and lead concentrations in domestic water. SETTING: Postcode districts of Glasgow supplied by water from the Loch Katrine reservoir. DESIGN: An ecological study. Lead concentrations from 1911 randomly selected domestic water samples were obtained from the Glasgow 93 lead study. Neural tube defects (affected births and terminations) were identified from the Glasgow register of congenital anomalies for the period 1983-95 for each postcode district in the study population. Correlations were sought between lead concentrations and pregnancy prevalence of neural tube defects/1000 live births in postcode districts. RESULTS: No correlation was found between domestic water lead concentrations > 10 microg/litre and pregnancy prevalence of neural tube defects within postcode districts. Areas of Glasgow previously with high domestic water lead concentrations did not have a higher prevalence of neural tube defects. Houses with the lowest domestic water lead concentrations were in Carstairs deprivation categories 1 (least deprived), 6, and 7 (most deprived). The highest pregnancy prevalence of neural tube defects was found in the most deprived areas. CONCLUSION: Deprivation is a risk factor for neural tube defects and might have been a confounding factor in previous studies looking at the association between such defects and domestic water lead concentrations. This study does not support the hypothesis that levels of lead > 10 microg/litre in domestic water supplies are associated with a higher pregnancy prevalence of neural tube defects. The reasons behind the decline in pregnancy prevalence of neural tube defects seen in the past two decades remain unexplained.

Asthma symptoms in women employed in domestic cleaning: a community based study.

BACKGROUND: Epidemiological studies have shown an association between cleaning work and asthma, but the risk factors are uncertain. The aim of this study was to assess the risk of asthma in women employed in domestic cleaning. METHODS: A cross sectional study was conducted in 4521 women aged 30 to 65 years. Information on respiratory symptoms and cleaning work history was obtained using a postal questionnaire with telephone follow up. Asthma was defined as reported symptoms in the last year or current use of drugs to treat asthma. Odds ratios (OR) with 95% confidence intervals (CI) for asthma in different cleaning groups were estimated using adjusted unconditional logistic regression models. RESULTS: 593 women (13%) were currently employed in domestic cleaning work. Asthma was more prevalent in this group than in women who had never worked in cleaning (OR 1.46 (95% CI, 1.10 to 1.92)). Former domestic cleaning work was reported by 1170 women (26%), and was strongly associated with asthma (OR 2.09 (1.70 to 2.57)). Current and former non-domestic cleaning work was not significantly associated with asthma. Consistent results were obtained for other respiratory symptoms. Twenty five per cent of the asthma cases in the study population were attributable to domestic cleaning work. CONCLUSIONS: Employment in domestic cleaning may induce or aggravate asthma. This study suggests that domestic cleaning work has an important public health impact, probably involving not only professional cleaners but also people undertaking cleaning tasks at home.

Assessing the offending activity of criminal domestic violence suspects: offense specialization, escalation, and de-escalation evidence from the Spouse Assault Replication Program.

OBJECTIVE: Over the past quarter century, intimate partner violence research has occupied an increasingly important position in the research agenda of criminology, public policy, and public health. Yet, a number of questions about the criminal careers of domestic violence offenders remain unresolved. This study attempts to determine (1) the extent to which criminal domestic violence offenders specialize in violence, and (2) whether the severity of an offender's attacks against the same victim increase, decrease, or stay about the same over time. METHODS: Data from the Spouse Assault Replication Program (SARP) are used to address two questions corresponding to different features of the criminal careers of domestic violence offenders. RESULTS: The specialization analysis reveals that the majority of domestic violence offenders with prior official criminal records have been involved in nonviolent forms of criminal behavior in addition to domestic violence. The escalation analysis identifies groups of escalators and de-escalators as well as individuals who engage in stable low-level aggression and stable high-level aggression. CONCLUSIONS: Few SARP domestic violence offenders have been specializing exclusively in violence. There is also a heterogeneous mix of offenders who escalate and de-escalate the severity of their attacks over the short-term follow-up periods. Few studies have presented data consistent with the present study's findings. A longitudinal analysis of the criminal careers of domestic violence offender subtypes is critical for future research.

Failure to maintain interspecific pregnancy after transfer of Dall's sheep embryos to domestic ewes.

Over a 3-year period, 32 Dall's sheep (Ovis dalli dalli) embryos were transferred into 24 domestic sheep (O. aries) recipients and 4 were transferred into 2 Dall's sheep recipients. In the first year, none of the 10 O. aries recipients was diagnosed pregnant. In the following 2 years, 9 (37%) of the domestic sheep recipients were pregnant on Day 18, 8 (33%) on Day 40, 6 (25%) on Day 90 and 4 (16%) on Day 120; 1 aborted at Day 125 and another at Day 145. Pregnancies were established only in ewes that had previously been recipients of Dall's sheep embryos. The 2 remaining pregnant sheep were treated with progesterone from Day 125 until the fetuses were determined to be dead at Day 145. Both of the Dall's sheep recipients (Year 2) established pregnancies; 1 live Dall's sheep lamb was born 174 days after mating. No differences in serum progesterone, oestrone, prostaglandin F-2 alpha metabolites or cortisol concentrations could be detected during pregnancy between recipients carrying Dall's sheep embryos, recipients receiving progesterone treatment or domestic ewes carrying domestic sheep pregnancies. Six fetuses were necropsied (1 at Day 125 and 5 at Day 145-146): all fetuses were premature and had various degrees of hydranencephaly. No significant differences were found when cotyledon numbers were compared among domestic ewes carrying Dall's sheep lambs. Dall's sheep ewes lambing naturally and domestic ewes lambing naturally. These results demonstrate that the transfer of Dall's sheep embryos to domestic ewes results in the establishment but subsequent loss of pregnancy and that these losses occur throughout gestation.

Gene flow between natural and domestic populations of Lutzomyia longipalpis (Diptera: Psychodidae) in a restricted focus of American visceral leishmaniasis in Venezuela.

The epidemiology of the visceral leishmaniasis in the Americas is associated with both a natural and a domestic cycle. The existence of reproductively isolated populations of Lutzomyia longipalpis (Lutz & Neiva), and the scarcity of records of this species from natural habitats in areas where it has been associated with domestic habitats indicated that natural populations could be genetically distinct from domestic ones. Therefore, we compared the genetic structure and estimated the gene flow between L. longipalpis from domestic and peridomestic habitat and from an adjacent undisturbed natural environment along a 1.2-km transect. The analyses were performed on electrophoretic data from eight isozyme loci. The absence of fixed differences in the diagnostic loci Ak and Hk indicated that all specimens belonged to one of the two cryptic species identified in Venezuela. The average number of alleles per locus ranged from 2.0 to 2.9 and the average heterozygosity ranged from 7.8 to 13.4%. No differences were detected in the genetic structure of this species from domestic or peridomestic habitats and those trapped as far as 1.2 km from human dwellings. Nm, estimated from Wright's Fst, indicated that at least 208 individuals per generation migrated between the peridomestic habitat and a 1.2-km distant point to maintain the observed similarities in allelic frequencies. This high rate of gene flow indicated that this species has high migration rates between domestic and natural environments, and has the potential to transport for Leishmania from natural to domestic environments.

Understanding domestic violence against women: using evolutionary psychology to extend the feminist functional analysis.

Evolutionary psychologists such as Wilson and Daly (1993b) hypothesize that one goal of male-perpetrated domestic violence is control over female sexuality, including the deterrence of infidelity. According to this hypothesis, domestic violence varies with women's reproductive value or expected future reproduction, declining steeply as women age. We tested this hypothesis with a sample of 3,969 cases of male-perpetrated partner-abuse reported to a single police precinct in a large urban area over a 14-year period. Results show that (a) rates of domestic violence decrease as women age, (b) younger men are at greatest risk for perpetrating domestic violence, (c) younger, reproductive age women incur nearly 10 times the risk of domestic violence as do older, post-reproductive age women, and (d) the greater risk of domestic violence incurred by reproductive age women is not attributable solely to mateship to younger, more violent men. Discussion addresses theoretical implications of these findings and suggests a refinement of the feminist hypothesis of domestic violence against women.

Domestic violence victims in a hospital emergency department.

OBJECTIVE: To determine the prevalence and predictors of domestic violence victims among attenders at the emergency department at Royal Brisbane Hospital in 1991. DESIGN: Cross-sectional study in which randomly selected nursing shifts were used to screen attenders. RESULTS: Of all attenders at the emergency department, 14.1% disclosed a history of domestic violence. Women were more likely than men to disclose domestic violence ("raw" relative risk, 2.31; 95% confidence interval [CI], 1.83-2.91; relative risk adjusted for age and history of child abuse, 4.50; 95% CI, 3.02-6.71). The greatest risks for being an adult victim of domestic violence were being female and having experienced abuse as a child. Most of those who had experienced domestic violence within the last 24 hours (1.1% of attenders) came to the department after-hours when social work staff were unavailable for referral. CONCLUSIONS: The prevalence and risk factors have implications for the training of doctors and nurses in domestic violence problems and for the provision of adequate resources to deal with the psychosocial aspects of domestic violence.

Susceptibility of phagocytes from elk, deer, bighorn sheep, and domestic sheep to Pasteurella haemolytica cytotoxins.

Alveolar macrophages and peripheral blood neutrophils from elk (Cervus elaphus), bighorn sheep (Ovis canadensis canadensis), and domestic sheep were exposed to culture supernatants from Pasteurella haemolytica isolated from bighorn sheep and domestic sheep. In a second experiment, peripheral blood neutrophils from mule deer (Odocoileus hemionus), elk, and bighorn sheep were exposed to culture supernatants from P. haemolytica isolated from elk, bighorn sheep and domestic sheep. Alveolar macrophages from elk, bighorn sheep and domestic sheep were resistant to killing by P. haemolytica supernatants from bighorn sheep and domestic sheep; susceptibility of neutrophils to cell death, as measured by release of lactate dehydrogenase, differed significantly (P < 0.05) between the four species tested. Bighorn sheep and domestic sheep neutrophils were susceptible to cytotoxin damage by the P. haemolytica isolates used; bighorn sheep neutrophils were four- to eight-fold more susceptible to cytotoxin damage than domestic sheep neutrophils. Neutrophils from deer and elk were resistant to killing by P. haemolytica cytotoxins from any species tested.

Domesticated birds as a model for the genetics of speciation by sexual selection.

In theory, even populations occupying identical environments can diverge in sexually selected traits, as a consequence of different mutational input. I evaluate the potential of this process by comparing the genetics of breeds of domesticated birds to what is known about the genetics of differences among species. Within domesticated species there is a strong correlation of time since domestication with the number of breeds. Descendants of the rock dove, Columba livia (the oldest domesticate) show differences in courtship, vocalizations, body shape, feather ornaments (crests and tails) and colors and color patterns. When nine other domesticated species are included there is a striking hierarchy, with more recent domesticates having a nested subset of these traits: the youngest domesticated species have breeds distinguished only by color. This suggests that selection of new, visible, mutations is driving the process of breed diversification, with mutations that appeal to the breeder happening the most frequently in color. In crosses among related species, color, feather ornaments and many vocalizations and displays show both intermediate dominance and pure dominance. Although the number of loci affecting each of these traits is typically unknown, limited evidence of the genetics of species' differences suggests that some differences are due to the substitution of single genes of major effect. While neither the genetics of breeds nor the genetics of species provide a perfect model for the genetics of speciation, similarities between the two are sufficiently striking to infer that major, visible, mutations can provide the impetus underlying new directions of sexual selection.

[Comparison of the pathogenesis and epizootiologic importance of avian mycobacteriosis in various types of domestic and free-living syntropic birds].

The sensitivity of domestic and different sorts of synanthropic free living fowl to M. avium and pathogenesis of tuberculous process were observed by experimental infections. The partridge, domestic fowl, pheasant and sparrow were the most sensitive to intramuscular infection by suspension of M. avium. The sparrow, domestic fowl, laughing gull were the most sensitive to peroral infection by food contaminated by tbc poultry liver. After free contact between the poultry, the domestic fowl was the most sensitive to infection and then the sparrow, turkey, guinea fowl, pheasant and partridge were sensitive, too. The tuberculous lesions were observed in majority of infected fowls in cases of guinea fowl, turkey, laughing gull, domestic fowl, sparrow, partridge and pheasant after all types of infections. The pigeon, rook and turtle-dove were very resistant to M. avium infection. The largest quantities of mycobacteria in tissues of infected fowl were found in sparrow and guinea fowl and then in domestic fowl, pheasant and partridge. From the results of patho-morphological and culture examinations, we can distribute the experimentally infected fowl in four groups: very sensitive-domestic fowl, sparrow, pheasant, partridge, laughing gull; little sensitive-guinea fowl, turkey; resistant-goose, duck; very resistant-pigeon, turtle-dove, rook. It is necessary to know that the sensitivity of these sorts of fowl can be affectable by conditions of experimental infection. If we want to criticize the epizootological importance of individual sorts of fowl as a source of M. avium, we must take into account their sensitivity to M. avium, pathogenesis of tuberculous process and their breeding or zoological specificities of individual sorts.

Population Genomics of Almond (Prunus dulcis) Reveals Region-Specific Selection and a Complex History of Domestication.

The domestication of perennial crops in the Mediterranean Basin remains unclear, particularly regarding the genomic consequences of human-mediated demographic shifts and selection. We analysed 8.1 million single nucleotide polymorphisms from 96 cultivated almond (Prunus dulcis) accessions from Europe, North America, Central Asia, and New Zealand, alongside four wild relatives. Population structure analyses revealed four geographically differentiated cultivated groups (Central Asian, North American, and two European) and three wild populations (P. spinosissima, P. orientalis, and P. fenzliana). Cultivated almonds retained high genetic diversity, consistent with weak domestication bottlenecks typical of outcrossing perennials. Elevated diversity and private allele counts in Central Asian cultivars, together with limited evidence of crop-wild gene flow, support Central Asia as an important reservoir of ancestral cultivated diversity that may have played a major role during the early stages of almond domestication. In contrast, allele sharing consistent with historical wild-to-crop introgression-especially involving P. orientalis-has contributed to the genomic composition of European and North American almonds. Genome-wide scans for selective sweeps showed most genes overlapping candidate sweep regions were population-specific, though often associated with similar biological functions, including stress responses and agronomic traits. This suggests repeated targeting of comparable pathways during and post-domestication, despite distinct selection histories. Notably, a subset of candidate genes detected in cultivated populations also occurs in wild relatives, particularly P. orientalis. This overlap is consistent with shared ancestral variation, introgression/gene flow between wild and cultivated lineages, and/or parallel adaptation. Altogether, our results support a complex domestication and diversification history for almonds, shaped by geographic expansion, gene flow with wild relatives, and recurrent selection acting in different regions. This study highlights wild relatives as important reservoirs of genetic diversity and emphasises the need for broader geographic sampling to clarify their contributions to almond domestication and adaptation.

Understanding Dynamics: A Systematic Review of the Attitudes, Knowledge, and Competencies of European Frontline Professionals Toward Domestic Abuse.

There remains a paucity of European research on attitudes and responses to domestic abuse from frontline workers and professionals who regularly encounter domestic abuse or engage with domestic abuse legislation. This systematic review synthesized qualitative, quantitative, and mixed-method peer-reviewed studies that explored professionals' knowledge, attitudes, and competencies related to domestic abuse. The professionals included medical staff (doctors, nurses, midwives), social care professionals, police officers, and criminal justice practitioners. The review was conducted on current European studies published between 2014 and 2025 and was reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Databases consulted included APA PsycInfo, Scopus, Web of Science, PubMed, Sociological Abstracts, International Bibliography of the Social Sciences, Social Services Abstracts, and Google Scholar. Full-text review was performed on 273 articles, of which 36 were deemed appropriate for inclusion. The review included 8 multi-country studies spanning the United Kingdom (England, Scotland, and Wales), and 28 single-country studies conducted in England, Sweden, Turkey, Portugal, the Republic of Ireland, Wales, Bosnia, Spain, Italy, Slovenia, and Hungary. A narrative and thematic synthesis categorized professional attitudes toward domestic abuse into four emergent themes: attitudes toward engagement and responsibility, attitudes toward victims, knowledge and understanding of domestic abuse, and attitudes as predictors of professional practice. This review addresses a dearth of research and provides recommendations for promoting proactive practice among professionals most likely to receive disclosures of abuse.
