Pig Carcasses

The domestic pig (Sus scrofa) was used as a model to study arthropod succession on carcasses under tree shade and out of shade in southern Nigeria. Carcass decomposition took longer periods under tree shade than in exposed sites, at 24.5 and 16.5 days, respectively. Four decomposition stages - fresh, bloated, decay, and dry - were observed. No significant variabilities were recorded in the types and patterns of infestation of the carcasses by arthropods in both locations. Four classes of arthropods - Insecta, Arachnida, Diplopoda and Crustacea - were recorded. The class Insecta dominated the total arthropods collected with 24 families, and formed 94% of the catches. The other three classes each had one family represented, and contributed only 2% of the total catches. The calliphorids, a phorid, and sarcophagids arrived and bred on the carcasses only a few hours after death of the pigs. Families of coleopterans came during the bloated stage, and fed on the immature dipterous maggots and carrion materials. The ants (Hymenoptera) came in large numbers to eat the carcasses, and also preyed on all other fauna of the food resource. A muscid and a stratiomyiid, bred on the carcass as to the decay stage. Other insects and arthropods arrived mostly during the decay stage to feed on the carcasses. Species richness on the carcasses peaked during the decay stage.

Hymenotpera species may act as necrophagous, consuming decomposing tissues, as predators, when they feed on other immature and adult insects, and parasites of larvae and pupae of dipterans and coleopterans that colonize the carcasses. In this way, the fauna of four Hymenoptera families (Vespidae, Apidae, Icheneumonidae and Formicidae) associated to different decomposition stages of Sus scrofa carcass partially submerged in igarapé of the “terra-firme” Amazonian forest are presented. Formicidae were the most abundant insects with 957 individuals collected all directly in the carcass, followed by Vespidae (143), Apidae (88) and Ichneumonidae with nine individuals collected in the suspended trap. Due to the aspect of the injuries caused by some Hymenoptera to the carcass, they may be mistaken as skin ulcers, burns or abrasions, which may mislead a forensic investigation.

Abstract Objective With the ongoing COVID-19 pandemic, large numbers of people will receive one of the several medications proposed to treat COVID-19, including patients of reproductive age. Given that some medications have shown adverse effects on sperm quality, there might be a transgenerational concern. We aim at examining the association between drugs proposed to treat COVID-19 when taken by the father around conception and any pre-term birth or major birth defects in offspring in a nation-wide cohort study using Danish registry data. Offspring whose father filled at least one prescription of the following medications in the 3 months preceding conception were considered exposed: chloroquine, hydroxychloroquine, losartan, azithromycin, naproxen, dexamethasone and prednisone. Results For azithromycin and naproxen, large numbers of offspring were exposed (> 1800 offspring), and we found no association with adverse birth outcomes. For chloroquine, losartan and dexamethasone, exposure was intermediate (~ 900 offspring), and there was no statistically significant association with birth defects. For hydroxychloroquine and prednisone, exposure was limited (< 300 offspring). Our evidence suggests that azithromycin and naproxen are safe with respect to pre-term birth and birth defects. For the other drugs investigated larger exposures are needed for conclusive statements.

Sus Scrofa Domesticus

Antemortem domestic pig (Sus scrofa domesticus) dental pathology literature is sparse. This observational descriptive study evaluated 23 client-owned pigs that while sedated/anesthetized for routine annual care had intraoral dental radiographs and an oral examination performed. Age, gender, weight, and breed for each pig were recorded. Oral examination and radiographic findings were reviewed to create a comprehensive list of dental abnormalities identified. Descriptive statistics were performed to summarize the data. The study population included 14 castrated males and 20 Vietnamese pot-bellied mini-pigs. The median age was 3 years (range 2-12 years), and the median weight was 39 kg (range 11-140 kg). The most common finding was missing teeth (21/23 pigs); the first premolar tooth was the most likely to be absent (64/106 missing teeth). Periodontal disease was common (20/23 pigs). Advanced stages primarily affected the first molar teeth frequently in the form of a mucogingival defect. Supernumerary roots were discovered on the maxillary canine teeth in female pigs only (10/25 teeth with supernumerary roots). The most common persistent deciduous tooth was the maxillary second incisor (15/19 persistent deciduous teeth). Non-age or gender related open apices were most likely associated with mandibular first and second incisor teeth (26/96 teeth with open apices). Tooth resorption was also identified (7/23 pigs). The study findings prove that pet pigs commonly have dental pathology; therefore, thorough oral examinations with intraoral radiographs should be included in porcine routine health care regimens.

To summarize the recent trials and studies of the role of beta-blocker on the treatment for cancer patients treated with anthracycline to decrease morbidity and mortality rate. Good management of cancer will result in large numbers of cancer survivors. On the other hand, cancer therapy also has side effects, one of which is cardiotoxicity. Cardiotoxicity could reduce therapy effectiveness, hence, increase disease progression and mortality rate. Anthracyclines is one of the chemotherapy agents with cardiotoxicity as a side effect. Beta-blocker has the ability to reduce cardiotoxicity due to anthracyclines usage. Keywords: Beta-blocker; Cardiotoxicity; Anthracyclines

Abstract Honey bees are very valuable to human. These social insects contribute in the pollination of many crops. Also, the products from honey bee colonies have many nutritional and medicinal benefits. Thus, keeping honey bees are very valuable and can be considered as source of income to many families. There are many diseases and pests that attack honey bee colonies. The pests attack bee colonies include: hornets, wax moths, bee-eater birds, and beetles. Such challenges can impact the survival and productivity of honey bee colonies. In this study, some beetle species belong to Fam. Nitidulidae, Dermestidae and Mycetophagidae were detected in honey bee colonies in Egypt, during spring. Despite the presence of many beetle species in the agricultural environment, only few species preferred the invasion of the colonies for feeding. These beetles do not attack stages of honey bees. They only feed on stored pollen or bee bread, especially those fallen on the bottom of the beehives. This is an alarm to follow the feeding behavior and distribution of these beetles. These beetles’ species can be considered as potential pests to weak honey bee colonies, housed in old or damaged beehives. The presence of large numbers of these beetles in weak colonies may disturb the activities of the bees and may passively impact the survival of the colonies. Listing these beetles is very important to better understanding the interaction between honey bees and beetles. On the other side, small hive beetles were not detected in the colonies. These beetles are currently one of the major problems facing honey bees in different parts of the world. This study confirms the absence of small hive beetles from Egypt.

The aim of our study was to assess the dynamics of the characteristics in pig carcasses as affected by the season and year of slaughter. A total of 106 027 carcasses of growing-finishing pigs of commercial production, slaughtered in the same abattoir in 2014 and 2015 were included in the study. The carcasses were classified using UltraFOM 200 device, as the characteristics controlled were back-fat thickness at two locations and the depth of m. Longissimus dorsi. These measurements were used to further determine the lean meat percentage. The results of the study showed significant differences in the dynamics of changes of carcass characteristics during the seasons and the years. The highest lean meat percentage was found in summer (56.48%), followed by spring (56.34%), autumn (56.29%) and winter (56.10%). On the other hand, the pigs slaughtered in winter displayed highest carcass weight and back-fat thickness at both locations.
