Abstract
Alpha mangostin (AM), isolated from G. mangostana, showed beneficial effects in several disorders due to its antioxidant and anti-inflammatory properties. Acute kidney injury (AKI) due to different etiologies can develop into severe complications, resulting in high mortality rates. In this work, AM is tested for its ability to alleviate AKI in glycerol-induced AKI rat model, where 30 Male Sprague-Dawley rats were assigned to a healthy group, glycerol-treated group and AM-treated group. Glycerol- and AM groups received a single dose of glycerol (per IM, 50% glycerol in saline, 8 ml/kg), whereas control group was injected with saline. AM treatment (a single daily dose, per IP, 175mg/kg) was accomplished for three days. Animals were executed to collect blood samples and kidney tissue for biochemical and histological examination. It was found that glycerol induced increase in serum creatinine, blood urea nitrogen (BUN), lipid peroxidation, serum magnesium, TNF-α and IL-6. It also induced renal edema and hypocalcemia along with histopathological renal damage. AM treatment improved renal histological features and alleviated increase in serum creatinine, BUN, serum magnesium, TNF-α and IL-6 levels, as well as renal edema and lipid peroxidation but did not affect serum calcium levels. This suggests AM as a potential therapeutic agent for treating AKI mainly via its antioxidant and anti-inflammatory properties.

Abstract
Using a songbird, zebra finches, as a developmental drug abuse model we found previously that cannabinoid agonists administered during the sensorimotor period of vocal learning (50-75 days of age) persistently alter song patterns and cocaine responsiveness in adulthood. However, these effects were not produced in adults exposed to similar treatment regimens. Currently, we have used the MAGL inhibitor, JZL184, to test whether enhanced endocannabinoid signaling may similarly alter cocaine responsiveness. We found that, as expected and consistent with prior results, repeated developmental (but not adult) treatments with Δ9-tetrahydrocannabinol (THC, 3 mg/kg QD IM) resulted in increased time spent in cocaine-paired chambers. Unexpectedly and in contrast, repeated developmental JZL184 (4 mg/kg QD IM) treatments decreased time spent in cocaine-conditioned chambers. That is, young finches repeatedly treated with JZL184 avoided cocaine-paired chambers later in adulthood, while similar development treatments with THC had the opposite effect. To begin to identify brain regions that may underly this differential responsiveness we used c-Fos expression as a marker of neuronal activity. Differences in c-Fos expression patterns following placement of cocaine-conditioned finches into vehicle- vs. cocaine-paired chambers suggest distinct involvement of circuits through striatal and amygdaloid regions in respective effects of THC and JZL184. Results demonstrate that, like exogenous cannabinoid exposure, inhibition of MAGL activity during late post-natal development persistently alters behavior in adulthood. Contrasting effects of THC vs. MAGL inhibition with JZL184 suggests the latter alters development of brain regions to favor promotion of aversive rather than appetitive cocaine responsiveness later in adulthood.

Abstract
BACKGROUND Acute paracetamol toxicity is a common and potentially life-threatening emergency causing liver failure that may necessitate liver transplantation. Unfortunately, current therapies are still defective. OBJECTIVES To investigate the protective effects exerted by Aleppo galls (Quercus infectoria Olivier) extract against acute paracetamol toxicity in mice. METHODOLOGY Eighteen mice were divided into three experimental groups, each included six mice in each group. The groups included: negative control group, paracetamol toxicity group that received an acute toxic intraperitoneal dose of paracetamol (250 mg/kg) for four consecutive days, and treatment group (received 250 mg/kg paracetamol followed few hours later by Aleppo galls extract for the same duration). Animals were anaesthetized using ether anaesthesia. Animals were sacrificed by decapitation and blood samples were drawn. Paracetamol toxicity effects versus Aleppo galls protection were evaluated on liver function tests, liver histology, serum cholesterol and serum triglycerides. RESULTS Acute paracetamol toxicity caused significantly elevated serum transaminases (ALT and AST), decreased serum albumin, and increased serum cholesterol and triglycerides. Aleppo galls extract exerted significant protective effects and restored near normal serum levels of the previously-mentioned parameters. Upon histopathological evaluation, mice in the control group showed normal hepatic architecture with preserved hepatic cords and sinuses. Acute paracetamol toxicity induced peripheral zonal degeneration with focal necrosis of the hepatic tissue. The hepatocytes showed cytoplasmic vacuolation with indistinct cell borders. Central hepatic venules were congested. Administration of Aleppo galls extract reduced the tissue damaging effects induced by paracetamol toxicity with only minimal residual degenerative changes that were observed with absent necrosis. CONCLUSION Quercus infectoria Olivier (Aleppo galls) is a promising source of phytochemicals and future therapeutics.

Abstract
BACKGROUND Paracetamol (acetaminophen) is an over-the-counter non-steroidal anti-inflammatory drug that may cause acute toxic overdosage particularly in neuropsychiatric patients. Paracetamol is also very commonly prescribed as an analgesic and antipyretic agent. Paracetamol toxicity causes decreased reduced glutathione and oxidative tissue damage. Aleppo galls is a promising natural remedy exerting antioxidant and tissue-protective effects that may combat acetaminophen-induced oxidative tissue damage. METHODOLOGY Biochemical and toxicological effects of a toxic dose of paracetamol (250 mg/kg) were investigated for three consecutive days versus the tissue-protective effects of Aleppo galls. Eighteen white albino mice were randomly allocated in this study and divided into three experimental groups (six mice per group): negative control (received intraperitoneal sterile water injection), paracetamol toxicity group (received intraperitoneal paracetamol injection) and the third group (received paracetamol injection at 250 mg/kg/day together with oral Aleppo galls treatment at 250 mg/kg/day for 3 consecutive days). All mice were sacrificed by the end of the study. RESULTS Our data revealed that paracetamol toxicity exerted significant oxidative stress damaging effects (high serum malondialdehyde, decreased serum catalase and decreased total antioxidant capacity), and significant inflammatory effects (high serum IL-6) and significant tissue-damaging effects (high serum LDH). Aleppo galls treatment significantly protected against acetaminophen toxicity-induced oxidative stress effects (P<0.001), inflammatory effects (P<0.001) and tissue-damaging effects (P<0.001). CONCLUSION Aleppo galls are promising for future drug therapeutics and for the synthesis of natural remedies for treating paracetamol toxicity. We recommend formulating Aleppo galls extract as a pharmaceutical nutrition and to be given to those who need to take large doses of paracetamol.

Abstract
The transmission of the severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) can occur through an airborne route, in addition to contaminated surfaces and objects. In hospitals, it has been confirmed by several studies that SARS‐CoV‐2 can contaminate surfaces and medical equipment especially in hospitals dedicated to coronavirus disease 2019 (COVID‐19) patients. The aim of this study was to detect the contamination of hands, objects, and surfaces in isolation rooms and also in outpatients' clinics in hospitals and polyclinics. Environmental contamination of public high‐touch surfaces in public facilities was also investigated during an active COVID‐19 pandemic. Random swabs were also taken from public shops, pharmacies, bakeries, groceries, banknotes, and automated teller machines (ATMs). Samples were analyzed for SARS‐CoV‐2 positivity using real‐time polymerase chain reaction. In the COVID‐19 regional reference hospital, only 3 out of 20 samples were positive for SARS‐CoV‐2 RNA. Hand swabs from SARS‐CoV‐2‐positive patients in isolation rooms were occasionally positive for viral RNA. In outpatients' clinics, door handles were the most contaminated surfaces. Dental chairs, sinks, keyboards, ophthalmoscopes, and laboratory equipment were also contaminated. Although no positive swabs were found in shops and public facilities, random ATM swabs returned a positive result for SARS‐CoV‐2. Although there is no longer a focus on COVID‐19 wards and isolation hospitals, more attention is required to decontaminate frequently touched surfaces in health‐care facilities used by patients not diagnosed with COVID‐19. Additionally, high‐touch public surfaces such as ATMs require further disinfection procedures to limit the transmission of the infection. SARS‐CoV‐2 RNA was detected in outpatient healthcare facilities. Most contaminated surfaces were door handles. Medical equipment were occasionally positive for SARS‐CoV‐2. Dental clinic door handles and chairs were contaminated. SARS‐CoV‐2 RNA was detected on ATM. Decontamination of high‐touch surfaces is essential.

Abstract
Cannabidiol (CBD), a non-euphorigenic compound derived from Cannabis, shows promise for improving recovery following cerebral ischemia and has recently been shown effective for the treatment of childhood seizures caused by Dravet and Lennox-Gastaut syndromes. Given evidence for activity to mitigate effects of CNS insult and dysfunction, we considered the possibility that CBD may also protect and improve functional recovery of a complex learned behavior. To test this hypothesis, we have applied a songbird, the adult male zebra finch, as a novel pre-clinical animal model. Their learned vocalizations were temporarily disrupted with bilateral microlesions of HVC (used as a proper name) a pre-vocal motor cortical-like brain region that drives song. These microlesions destroy about 10% of HVC, and temporarily impair song production, syntax and phonology for about seven days. Recovery requires sensorimotor learning as it depends upon auditory feedback. Four CBD doses (0, 1, 10 and 100 mg/kg) within three surgery conditions (microlesion, no-microlesion, sham-microlesion) were evaluated (n = 5-6). Birds were recorded over 20 days: three baseline; six pre-microlesion drug treatment days and; 11 post-microlesion treatment and recovery days. Results indicate 10 and 100 mg/kg CBD effectively reduced the time required to recover vocal phonology and syntax. In the case of phonology, the magnitude of microlesion-related disruptions were also reduced. These results suggest CBD holds promise to improve functional recovery of complex learned behaviors following brain injury, and represent establishment of an important new animal model to screen drugs for efficacy to improve vocal recovery.
