Examining the Influence of Zinc Oxide Nanoparticles and Bulk Zinc Oxide on Rat Brain Functions: a Comprehensive Neurobehavioral, Antioxidant, Gene Expression, and Histopathological Investigation.

The study aimed to assess the impact of zinc oxide nanoparticles (ZnONPs) on rats' neurobehavior compared to bulk zinc oxide (BZnO). Thirty male Sprague-Dawley rats were randomly assigned to five groups. The control group received Tween 80 (10%), while the ZnONP groups were given ZnONPs at 5 and 10 mg/kg body weight dosages, and the bulk zinc oxide (BZnO) groups received BZnO at the same dosages.

Lateralised Behavioural Responses in Livestock to Environmental Stressors: Implications for Using Infrared Thermography to Assess Welfare Conditions.

Lateralised behavioural responses to environmental stressors have become more frequently used as indicators of social welfare in animals. These lateralised behavioural responses are under the control of asymmetrical brain functions as part of the primary functions of most vertebrates and assist in primary social and survival functions. Lateralised behavioural responses originating from the left hemisphere are responsible for processing familiar conditions, while the right hemisphere is responsible for responding to novel stimuli in the environment.

Tend and Befriend in Horses: Partner Preferences, Lateralization, and Contextualization of Allogrooming in Two Socially Stable Herds of Quarter Horse Mares.

Studies show that horses express favoritism through shared proximity and time and demonstrate unique affiliative behaviors such as allogrooming (mutual scratching) with favorite conspecifics. Allogrooming also occurs more frequently during stress and has been observed to occur more frequently in domestic herds than feral. The role of partner preference, lateralization, and duration of allogrooming as measures of social bonding has remained unclear.

'Can They Take the Heat?'-The Egyptian Climate and Its Effects on Livestock.

Egypt already has conditions in summer that cause heat stress for livestock, and predicted climate changes suggest that these will be exacerbated over the course of this century. As well, extreme climatic events make the mitigation of climate change difficult but important to understand. Apart from neonates, farm animals have upper critical temperatures in the region of 25-30 °C, whereas temperatures in summer regularly exceed 40 °C for prolonged periods.

Hepatorenal protective effect of nano-curcumin against nano‑copper oxide-mediated toxicity in rats: Behavioral performance, antioxidant, anti-inflammatory, apoptosis, and histopathology.

Background: Metal oxide nanoparticles (NPs) induce oxidative stress that can cause cellular toxicity. A natural antioxidant that can be used to protect tissues from oxidative stress is curcumin.

Purpose: In the present study, we evaluated the protective effect of curcumin nanoparticles (curcumin-NPs) against copper oxide nanoparticles (CuO-NPs)-mediated hepatorenal effects on behavioral performance, biochemical markers, antioxidants, inflammation, apoptosis, and histopathology in rats.

The Impact of Anthropogenic Climate Change on Egyptian Livestock Production.

Egypt is one of the hottest countries in the world, and extreme climate events are becoming more frequent, which is consistent with the warming of the planet. The impact of this warming on ecosystems is severe, including on livestock production systems. Under Egyptian conditions, livestock already suffer heat stress periods in summer.

Insight Study on the Comparison between Zinc Oxide Nanoparticles and Its Bulk Impact on Reproductive Performance, Antioxidant Levels, Gene Expression, and Histopathology of Testes in Male Rats.

Despite the beneficial effects of zinc oxide nanoparticles (ZnONPs) on different biomedical applications, including their antioxidant and anti-inflammatory ones, it might have cytotoxic and genotoxic impacts on the male reproductive system. The current study compares the effect of zinc oxide nanoparticles and their bulk form, at different doses, on male rats' reproductive performance, testicular antioxidants, gene expression, and histopathology. Thirty male rats were randomly allocated equally in five groups.

Protective effect of methylene blue against copper oxide nanoparticle-induced neurobehavioral toxicity.

Increasing attention has been paid in the past decade to assessing the toxicological effects of nanoparticles and finding a protectant; thus, the current study aimed to investigate the protective effect of the mitochondria-targeting drug methylene blue (MB) against copper oxide nanoparticle (CuO-NP)-induced neurobehavioral toxicity in rats. For this purpose, twenty rats were allocated to four equal groups (n = 5). The negative control group received distilled water intraperitoneally (IP) and Tween 80 (10 %) orally.

The eyes have it: lateralized coping strategies in cattle herds responding to human approach.

We report a range of lateralized coping strategies adopted by large social groups of cattle in response to mild challenges posed by humans of varying degrees of familiarity. At either 14 or 18 pens at a commercial feedlot, with 90 to 200 cattle in each, we conducted a series of video recorded 'pressure tests'. 'Frontal' pressure tests involved walking from a position perpendicular to the concrete feed bunk of a given pen, towards the geometric centre of the line of feeding cattle.

Respiratory, ocular and skin health in recreational and competitive swimmers: Beneficial effect of a new method to reduce chlorine oxidant derivatives.

Background: Chlorine by-products may irritate the eyes, nose, skin and airways of swimmers and may cause chronic airway inflammation.

Objective: To assess the salutary effects on swimmers health of a new method of water disinfection.

Methods: Recreational (n=320) and competitive swimmers (n=53) participated in the study.

Multidrug resistance protein 1 localization in lipid raft domains and prostasomes in prostate cancer cell lines.

Background: One of the problems in prostate cancer (CaP) treatment is the appearance of the multidrug resistance phenotype, in which ATP-binding cassette transporters such as multidrug resistance protein 1 (MRP1) play a role. Different localizations of the transporter have been reported, some of them related to the chemoresistant phenotype.

Aim: This study aimed to compare the localization of MRP1 in three prostate cell lines (normal, androgen-sensitive, and androgen-independent) in order to understand its possible role in CaP chemoresistance.

Benefits of carbon dioxide as pH reducer in chlorinated indoor swimming pools.

Carbon dioxide is seldom used as pH reducer in swimming pools. Nevertheless it offers two interesting advantages. First, its use instead of the usual hydrochloric acid avoids the characteristic and serious accident of mixing the disinfectant with that strong acid, which forms a dangerous chlorine gas cloud and, second, it allows the facility to become slightly a depository of that greenhouse gas.

Macrocephaly-cutis marmorata telangiectatica congenita: report of six new patients and a review.

We report on six additional patients with macrocephaly-cutis marmorata telangiectatica congenita (M-CMTC; MIM 602501) and review the literature. This syndrome is a multiple congenital anomalies/mental retardation and overgrowth disorder comprising macrocephaly, cutis marmorata, vascular marks of lip and/or philtrum, syndactyly, hemihypertrophy, CNS anomalies, and developmental delay. Based on the findings in our 6 patients and on 69 patients previously reported we listed the very frequent (observed in >75%), frequent (25-75%), and less frequent (>25%) components of the syndrome.
