Abstract: The purpose of the study is to determine how geographical proximity, climate, and topography influence the morphology of village chickens in Jordan’s Karak Governorate. Surveys were conducted in six regions of Karak as well as Tafilah, Madaba, Aqaba, and Al-Mafraq governarates. These governarates were included because they are geographically close to Karak Governorate and can be compared in terms of topography and climate. The morphology and biometric data of each male and female bird, including the exterior shape of the bird, body weight, colors, and measurements of body parts, were recorded during a field survey in the targeted regions. Each breeder’s information was gathered, and each chicken was photographed separately. Afterward, various statistical analyses were utilized to distinguish between morphological traits, perform clustering, and conduct differential analyses. The Mahalanobis distances (measure of the distance between a point P and a distribution D) were also calculated and estimated. The findings demonstrated that there are disparities in the phenotypic features of chickens between the sexes and between geographical areas. Village chickens are still raised in a traditional manner; as a result, there have been no genetic improvement techniques used or gene flow from geographically remote regions. Also as a result, chickens in Karak Governorate still resemble one another and their ancient ancestors in terms of morphological traits. In all regions and in both genders, the dominating traits were the pink color and single comb, the beige beak, the orange eye color, and the red earlobe with white speck. The difference in regions and height led to a significant difference in the appearance of traits in males and females.

Abstract: Indigenous chickens of Jordan are facing extinction and need genetic conservation because they were unable to commercially compete in the poultry industry because of low genetic ability compared to commercial layers. The study aimed to investigate phenotypic and genetic diversity of village chickens in Jordan using discriminant analyses procedures to provide a basis for sustainable genetic conservation and utilization program to overcome any possible extinction. The sampled chicken population of 578 one-year old chickens (125 males and 433 females) was phenotypically characterized for 15 biometric and plumage traits from major cities of the three regions; Middle, North, and South. The traits variations within and between breeds were detected statistically by stepwise discriminant and canonical-discriminant of uni- and multivariate analyses. The results showed the sampled population as village chickens in Jordan is comprised of indigenous (Baladi) breed (85%) and few exotic and commercial breeds. The breeds were distinct and differentiated based on phenotypic traits indicating high genetic variability. The major phenotypic traits that showed significant power to differentiate breeds were comb type, body weight, comb size, earlobe color, wattle size, face color and breast size in males and comb type and size, body weight, face and breast size, leg color and wattle size in females. Recent and past crossings, admixture or migration from exotic and commercial breeds were noted. Moreover, low levels of phylogeographic structure were observed across the studied breeds. In conclusion, there is a need to conserve the indigenous breed in situ and in vivo for its adaptive gene pool in the coming days of persisted climate change and disease threats.

Abstract: In Jordan, the public is still unaware of the fate and impact of pesticide application. This study aimed to evaluate the attitudes, knowledge and practices of undergraduate students enrolled in various academic departments at the Faculty of Agriculture, Mutah University, Jordan toward pesticides’ residues in food and feed. Students were questioned about their social aspects, and food and feed safety knowledge and resources. Responses have been obtained from 209 responding students. Results indicated that the cross-section through the Faculty of Agriculture, Mutah University, Jordan appears a satisfactory. The findings show that respondents are very highly concerned about human health, food safety, and the risk of environmental pollution, and they have a real desire to reduce the use of pesticides. Respondents had a moderate level of knowledge about food safety, pesticides’ side effects, pesticides’ residues in food or feed, and usage of pesticides in homes and gardens. According to the respondents, the most common way that people are exposed to pesticide residues is by consuming pesticide residues in food. The respondents expressed a moderate level of concern about their attitudes toward organic farming adoption. Correlations between demographic variables and knowledge of food and feed safety, involving a workshop on food/feed safety, care about human health as well as environmental pollution, and looking for information on food/feed safety were reported in the study.

Abstract: Drug addiction affects both brain and behavior. It has multifaceted impacts on the patients’ body, mind, and nervous system. There are different types of drugs that cause addiction as marijuana, opium, cocaine, heroin, meth and pain medications. Drug abuse is considered as a great challenge to social and public heath in the world. To date, 185 million addicts are there around the world. According to the statistics, with 1,200,000 permanent drug abusers and 600,000 occasional abusers [1], herbal medicine has a long history in treatment of diseases and the majority of people have tendency to use such medications. But there are a lot of questions because of the novelty of this treatment method in treating addiction, this lack of information are more evident. In this review, we highlighted on some herbal and drugs derived from them in treatment of addiction

Abstract: Coronavirus disease 2019 (COVID-19) is one of the worst pandemics, responsible for huge losses in economy and healthcare sectors all over the world. In addition to mortality, COVID-19 disease causes several types of pain during viral infection and after recovery. Inflammatory and neuropathic pain were reported in COVID-19 patients. Unfortunately, using many of the available drugs aggravated COVID-19 symptoms in patients and increased patients' susceptibility to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). There is a need for new therapeutics that can alleviate rather than aggravate COVID-19 symptoms. In this book, the author provides an introduction to the COVID-19 disease, pain in COVID-19 patients, the involvement of pain receptors in several symptoms that frequently appear in COVID-19 patients and an opinion on potential approaches for the alleviation of COVID-19 symptoms. In more detail, the author, herein, highlights the possible involvement of the transient receptor potential (TRP) channels, cannabinoid (CB) receptors, peroxisome proliferator-activated receptors (PPAR) and opioid receptors in COVID-19 symptoms in parallel with the crosstalk between these receptors.

Research Title: Nongenomic activation of the GC-A enzyme by resveratrol and estradiol downstream from membrane estrogen receptors in human coronary arterial cells.

Abstract: Abstract Background and aim: Resveratrol (RSVL), a polyphenolic phytoestrogen in grapes, confers multifaceted cardiovascular benefits. The cellular and molecular basis of RSVL actions has been largely undefined until now. Methods and results: In human coronary smooth muscle cells (HCSMCs), RSVL markedly (3.2-fold) enhanced cGMP formation (t(1/2): 6.3 min, EC(50): 1.8 microM) and stimulated kinase-G activity (4-fold). By contrast, RSVL had no effect on cAMP or PKA activity in these cells. The RSVL-enhanced cGMP/kinase-G activity was not abrogated by the nitric oxide synthase-inhibitor (L-NMMA, 10 microM), or the soluble guanylyl cyclase (sGC)-inhibitor (ODQ, 10 microM). In membrane preparations from HCSMCs, RSVL activated GC in the particulate-, but not in the soluble-membrane fraction. Similar effects were due to the specific particulate-GC-A agonist atrial natriuretic peptide (ANP, 0.1-1 microM). The combined effects of RSVL and ANP were competitive. By contrast, the selective GC-B agonist (BNP) showed no response on cGMP, whereas that for GC-C (guanylin) produced only slight increases in cGMP levels. Estradiol (E2) mimicked the effects of RSVL on cGMP, but showed a 46% lower maximal response. Combining E2 with RSVL showed a competitive, rather than an additive, response. Further, cGMP formation by RSVL or E2 was significantly attenuated by the pure estrogen receptor blocker, ICI-182,780 (10 microM). Conclusion: These findings are the first to link RSVL with pGC/kinase-G activation downstream from membrane ERs in the vasculature, thus substantiating its coronary protective effects, even in endothelium-disrupted coronary arteries.
