Crisis and environmental governance decisions amidst the COVID-19 pandemic: Lessons from European countries.

This study investigates the influence of the COVID-19 pandemic crisis on environmental governance decisions within publicly listed European companies. It utilizes a comprehensive analysis of publicly available data regarding these firms and check the environmental governance practices during the pandemic, informed by risk society theory which describes modern societies marked by ongoing risks and uncertainties primarily stemming from technological and scientific advancements. The regression and robustness analysis has been performed on how companies have responded to the crisis, specifically in terms of their approaches to environmental sustainability and governance. Covid-19 has a significantly positive impact on environmental governance (EG), with a coefficient of 18.73 and a p-value of .000. Other variables like human development (HD), size, and free cash flow (FCF) positively affect EG, while corruption (Corrupt) and leverage (Lev) have a negative influence. Robust analysis confirms the negative impact of Covid-19 on EG, with a coefficient of 18.46 and a p-value below .01, consistent across different subsamples. However, it also underscores the challenges companies have encountered in upholding their sustainability efforts amid the crisis. In sum, this research offers valuable insights into how the COVID-19 pandemic has affected environmental governance decisions, with potential implications for policymakers, regulators, and business leaders striving to advance sustainability in the post-pandemic landscape.

Therapeutic benefits of prophetic medicine remedies in treating hematological diseases (A review article).

Hematological disorders are common medical ailments constituting an important cause of morbidity and mortality worldwide, which may be managed efficiently using different prophetic medicine remedies as adjuvants to current therapeutics. Prophetic medicine includes the body of knowledge about medicine that has been derived from the deeds, customs (sunnah), ahadith (sayings), actions, and agreements of Prophet Muhammad, peace be upon him. This review article aims at exploring the magnitude of therapeutic benefits of prophetic medicine remedies as adjuvant treatments to many different types of hematological disorders. Herein, we reviewed many published research studies throughout the literature to delineate the potential therapeutic benefits of prophetic remedies on hematological disorders. Several types of hematological disorders may benefit from prophetic medicine remedies that are rich in natural antioxidants that combat oxidative stress-induced harm e.g. nigella sativa, oral honey, camel milk and urine, Ajwa date fruits, olive oil, Zamzam water and figs. Many prophetic medicine remedies were reported to decrease the hematological cytotoxicity effects induced by different chemicals and are beneficial in treating anemias e.g. iron deficiency anemia, sickle cell anemia, thalassemia, coagulopathies and hematological malignancies as leukemia and myeloma. These remedies treat or alleviate the different hematological disorders using different mechanisms e.g. modulating the immune function, treating deficiencies of different substances, protecting against toxins-induced cytotoxicity, decreasing platelets aggregation, suppressing clotting factors activation, exerting antineoplastic effects (enhancing cancer cells cytotoxicity) and inhibiting angiogenesis. Prophetic medicine remedies exert clinically significant therapeutic benefits for treating COVID-19 pandemic, anemia, thrombosis, thalassemia and blood cancers without inducing toxicity or side effects.

Do natural resources affect environmental quality in MINT Economies? The role of tourism and financial development.

With the growing nature of the ecological footprint, research studies focus on exploring new determinants of environmental degradation. Moreover, the role of natural resources and energy consumption in environmental quality has gained much attention in the literature. However, tourism raises the demand for energy consumption and extraction of natural resources. This research study investigates the influence of natural resources, tourism, and renewable energy in MINT countries, using novel Cross-Sectional Auto Regressive Distributive Lag (CS-ARDL) methodological techniques and employing yearly data from 1995 to 2018. The study also applied recently developed Kónya (Econ Model 23:978-992, 2006) causality to identify the causal relationship between the variables of the heterogenous panel. The result shows that tourism, natural resources, and economic growth are positively associated with the ecological footprint in the long-run. However, renewable energy consumption negatively impacts ecological footprint in both in short-run and the long-run. Further, the study explored a bidirectional causality between economic growth and ecological footprint in MINT countries. Finally, based on the empirical results, the study recommends that the authorities in MINT countries revisit their tourism, natural resources, and economic activities policies to enhance the environmental quality and reduce the ecological footprint.

Investigating the financial market development and shadow economy nexus in the presence of country risk in an emerging economy.

This research study examined the influence of financial market development on the shadow economy and the moderating effect of country risk (political, economic, and financial) in this nexus in Pakistan. Using data from 1995 to 2018, the study applied the Augmented Dickey-Fuller (ADF) and Phillips-Perron (PP) unit root tests, followed by the F-bounds test to investigate stationarity and cointegration in the series, respectively. The study utilized the Autoregressive Distributed Lag (ARDL) approach to estimate the long-run relationship, and to examine the possible causal relationship among the variables, the study employed Breitung and Candelon's (2006) spectral test. The study identified that financial market development is negative, and the country's risk determinants are positively associated with the shadow economy's size. Moreover, the study found that country risk positively moderates the influence of financial market development on the shadow economy. The results also highlighted a unidirectional relationship from economic and financial risk towards the shadow economy. Finally, based on the empirical findings, the study recommends some policy implications to the regulators of financial markets and the shadow economy.

Predictive Factors and Interventional Modalities of Post-stroke Motor Recovery: An Overview.

Stroke is the most common cause of motor impairment worldwide. Therefore, many factors are being investigated for their predictive and facilitatory effects on recovery of motor function after stroke. Motor recovery can be predicted through several factors, such as clinical assessment, clinical biomarkers, and gene-based variations. As for interventions, many methods are under experimental investigation that aim to improve motor recovery, including different types of pharmacological interventions, non-invasive stimulation, and rehabilitation training by inducing cortical reorganization, neuroplasticity, angiogenesis, changing the levels of neurotransmitters in the brain, and altering the inflammatory and apoptotic processes occurring after stroke. Studies have shown that clinical biomarkers combined with clinical assessment and gene-based variations are reliable factors for predicting motor recovery after stroke. Moreover, different types of interventions such as pharmacological agents (selective serotonin reuptake inhibitors {SSRI}, noradrenaline reuptake inhibitors {NARIs}, levodopa, and amphetamine), non-invasive stimulation, and rehabilitation training have shown significant results in improving functional and motor recovery.

Epidemiological Trends and Clinical Characteristics of Childhood Leukemia in Saudi Arabia: A Review.

Leukemia is the most prevalent type of cancer among children in Saudi Arabia. It has variable clinical presentations and accounts for a large scale of mortality and morbidity. Acute lymphoblastic leukemia (ALL) constituted the majority of pediatric leukemic cases with male gender predisposition. The most common first presentation that patients come with are manifestations of anemia, thrombocytopenia, and fever. Bone pain, fatigue, weight loss, organomegaly, and pale skin are among the commonest manifestations of pediatric leukemia. Childhood ALL and acute myeloid leukemia (AML) clinical manifestations seem to be very similar, even though there're some considerable differences in how common the clinical characteristics are. Chromosomal abnormalities are taken into consideration to determine survival and treatment. PubMed and Google Scholar were searched for the childhood leukemia population in Saudi Arabia. Our review article aims at providing comprehensible and updated statistical data on the different types of leukemia and their clinical presentations in Saudi Arabia.

Tobacco chewing and risk of gastric cancer: a case-control study in Yemen.

This study aimed to assess the risk factors for gastric cancer in Yemen. A hospital-based case-control study of 70 cases and 140 controls was carried out in Sana'a city between May and October 2014. A structured questionnaire was used to collect information through direct interview. Living in rural areas, tobacco chewing and drinking untreated water were significant risk factors for gastric cancer. Frequent consumption of chicken, cheese, milk, starchy vegetables, cucumber, carrots, leeks, sweet pepper, fruit drinks, legumes and olive oil were associated significantly with decreased risk of gastric cancer. Multiple logistic regression analysis showed that chewing tobacco and frequent consumption of white bread were associated with increased risk of gastric cancer, whereas frequent consumption of chicken, cooked potatoes and fruit drinks had an inverse association. Risk of gastric cancer can be prevented by health education and increasing community awareness.

La présente étude avait pour objectif d'évaluer les facteurs de risque du cancer de l'estomac au Yémen. Une étude cas-témoin en milieu hospitalier impliquant 70 cas et 140 témoins a été menée dans la ville de Sanaa entre mai et octobre 2014. Un questionnaire structuré a été utilisé pour collecter des informations au cours d'entretiens directs. La résidence en zone rurale, la consommation de tabac à chiquer et d'eau de boisson non traitée constituaient des facteurs de risque significatifs pour le cancer de l'estomac. Une consommation fréquente de poulet, de fromage, de lait, de légumes riches en amidon, de concombres, de carottes, de poireaux, de poivrons, de boissons fruitées, de légumes et d'huile d'olive était fortement associée à une diminution du risque de cancer de l'estomac. L'analyse de régression logistique multiple a montré que le tabac à chiquer et une consommation fréquente de pain blanc étaient associés à une augmentation du risque de cancer de l'estomac, tandis que la consommation fréquente de poulet, de pommes de terre cuites et de boissons fruitées avait une association inverse. Il est possible de prévenir le risque de cancer de l'estomac grâce à une éducation en santé et à la sensibilisation de la communauté

Genotoxicity following Organophosphate Pesticides Exposure among Orang Asli Children Living in an Agricultural Island in Kuala Langat, Selangor, Malaysia.

BACKGROUND: Agriculture is an important sector for the Malaysian economy. The use of pesticides in agriculture is crucial due to its function in keeping the crops from harmful insects. Children living near agricultural fields are at risk of pesticide poisoning. OBJECTIVE: To evaluate the genotoxic risk among children who exposed to pesticides and measure DNA damage due to pesticides exposure. METHODS: In a cross-sectional study 180 Orang Asli Mah Meri children aged between 7 and 12 years were studied. They were all living in an agricultural island in Kuala Langat, Selangor, Malaysia. The data for this study were collected via modified validated questionnaire and food frequency questionnaire, which consisted of 131 food items. 6 urinary organophosphate metabolites were used as biomarkers for pesticides exposure. For genotoxic risk or genetic damage assessment, the level of DNA damage from exfoliated buccal mucosa cells was measured using the comet assay electrophoresis method. RESULTS: Out of 180 respondents, 84 (46.7%) showed positive traces of organophosphate metabolites in their urine. Children with detectable urinary pesticide had a longer tail length (median 43.5; IQR 30.9 to 68.1 µm) than those with undetectable urinary pesticides (median 24.7; IQR 9.5 to 48.1 µm). There was a significant association between the extent of DNA damage and the children's age, length of residence in the area, pesticides detection, and frequency of apple consumption. CONCLUSION: The organophosphate genotoxicity among children is associated with the amount of exposure (detectability of urinary pesticide) and length of residence in (exposure) the study area.

Medical education in Saudi Arabia: a review of recent developments and future challenges.

Medical education has been changing rapidly in Saudi Arabia. Within a decade, the number of medical colleges increased from 5 medical schools with traditional disciplined-based curricula to 21 medical colleges with varied curricula ranging from the traditional to more innovative, problem-based, community-oriented programmes. The private sector has started investing in higher education generally and medical education in particular. Also other government sectors that provide advanced health services have started established new medical colleges. The expansion of quantity in medical education has been associated with a drive for greater quality assurance. Accreditation of higher education institutes began with the establishment of the National Commission for Academic Assessment and Accreditation in 2005. This review focuses on documenting developments in Saudi medical education up to 2008 and discussing the future potential and challenges facing the sector.

Better diagnosis and treatment of throat infections caused by group A beta-haemolytic streptococci.

This study aims to assess the diagnostic value of a rapid streptococcal antigen test in addition to four clinical features in patients with sore throat, using throat culture and antibody titre as reference tests, and to evaluate the efficacy of the current antibiotics used in the treatment of throat infections caused by group A beta-haemolytic streptococcus (GABHS). Four clinical features (fever [history of] > or = 38 degrees C, lack of cough, tonsillar exudate, and anterior cervical lymphadenopathy) are recorded in 355 patients aged four years to > or =15 years. A rapid antigen diagnostic test (RADT) is performed, as well as a throat culture. Antistreptolysin O (ASO) titre is performed in patients 11 years. GABHS from patients are tested for susceptibility to different antibiotics. Throat cultures were positive for GABHS in 19% patients. Rapid tests were positive in 24%. Compared with throat culture, the rapid test gave a sensitivity of 91%, specificity of 91%, positive predictive value of 73% and a negative predictive value of 98%. For patients with three or four clinical features, however, the sensitivity was considerably higher at 97%. Using the ASO test as a reference, no association was found between RADT and culture results. Zithromax showed the highest prescription rate (25.5%) and produced a high cure rate (91%) in patients with GABHS pharyngitis.

Immunogenicity of influenza and HSV-1 mixed antigen ISCOMs in mice.

Immunostimulating complexes (ISCOMs) were prepared with mixtures of antigens from influenza A virus (A/PR/8/34 or A/Sichuan/2/87) and herpes simplex virus type 1 (HSV-1), and were characterised by enzyme linked immunosorbent assay (ELISA) and electron microscopy using double-labelling immunogold techniques employing monoclonal antibodies to influenza or HSV-1 glycoproteins. The immunogenicity of the mixed antigen ISCOMs was evaluated in mice, following administration by the subcutaneous route, by measuring the total and subclass IgG antibody responses. Protection of these animals against challenge with live influenza A/Sichuan virus or live HSV-1, was compared with that induced by immunization with aqueous mixed antigen preparations. It was found that relatively high humoral responses to both influenza and HSV antigens, and increased levels of protection to both influenza and HSV viruses were elicited in mice receiving the mixed antigen ISCOM preparation compared to those observed in animals receiving the mixed aqueous subunit preparation. The findings also indicate that antigens from more than one virus can be used in an ISCOM formulation to produce immunity and protection.

Comparative antibody responses and protection in mice immunised by oral or parenteral routes with influenza virus subunit antigens in aqueous form or incorporated into ISCOMs.

The total and subclass antibody responses of mice and protection of these animals against live influenza A/Sichuan/2/87 virus challenge infection were determined after immunisation with homologous A/Sichuan/87 aqueous or ISCOM-formulated surface glycoprotein subunit antigens administered by either the oral or intramuscular routes. The results show that the greatest systemic and local antibody responses were elicited in mice immunised with A/Sichuan ISCOMs by the intramuscular route; protection against homologous virus challenge was also effective in these animals, particularly after two doses of the vaccine. However, relatively high immune responses and protection were also elicited by the A/Sichuan/87 ISCOM vaccine administered orally. Immunisation of mice by the intramuscular route resulted in levels of serum IgG2a subclass antibody significantly greater than those induced by the same preparation given by the oral route, or by the aqueous A/Sichuan/87 subunit antigen preparation administered by either route. The findings indicate that the ISCOM delivery system can be used for immunisation by the oral route, although in mice, under the conditions used, this strategy compares unfavourably with the intramuscular route in terms of both local and systemic immune responses and protection against homologous challenge virus infection.

Methylation of CpG-island-containing genes in human sperm, fetal and adult tissues.

The methylation of three human genes containing CpG islands and a CpG-depleted gene were measured in sperm, fetal and adult tissues. The c-Ha-ras was methylated extensively in the 3' region in sperm with a methylation-free region extending from the promoter to the third exon. The extent of methylation in the 3' region decreased in fetal cells, however, de novo methylation of sites closer to the island and within exon 1 were apparent. These sites were more completely methylated in adult lymphocytes and kidney. Essentially similar results were obtained with the CpG-island-containing genes, c-myc and HPRT (encoding hypoxanthine phosphoribosyl transferase), which showed that unmethylated sites near the CpG islands in sperm became methylated in fetal and adult cells. The variations in methylation seen in the non-island regions of the c-Ha-ras gene were mirrored in the insulin-encoding gene which does not contain a CpG island. The results show similar variations in methylation of non-island regions of DNA which occur independent of expression, and show that regions of extensive methylation in sperm may move closer to CpG islands in fetal and adult somatic cells.

Delivery outcome after infertility--a registry study.

Among a total of 379,779 women with 383,589 infants born in Sweden (1983 to 1986), 7.8% had a recorded period of infertility of at least 1 year. Women with a history of infertility had a higher mean age, a lower parity, had fewer previous induced abortions but more spontaneous abortions, extrauterine pregnancies, and stillbirths than women without a history of infertility. They also smoked more. There was an excess of multiple births. Singleton infants showed an increased percentage of low-birth weight infants, short gestational duration, and signs of intrauterine growth retardation. The rate of major malformations was not increased in the total infertile group but may have been increased in the subgroup with at least 4 years of infertility.

Changes in the allelic methylation patterns of c-H-ras-1, insulin and retinoblastoma genes in human development.

The methylation status of the c-H-ras-1, insulin and retinoblastoma genes was determined in human sperm, hydatidiform mole, fetal tissues, adult lymphocytes and adult kidney. Individual alleles of c-H-ras-1 and insulin were distinguishable due to presence of endogenous variable number of tandem repeat (VNTR) polymorphisms. Both alleles of the latter two genes were extensively methylated in sperm compared to the other tissues. Several sites within these genes were less methylated in fetal tissues and the two alleles were differentially methylated in some cases. The retinoblastoma gene was highly methylated in all tissues examined, with the exception of a single site that was under-methylated in sperm only. The sperm-specific methylation patterns in all three genes could represent imprinting of the parental chromosomes. Since 5-methylcytosine is inherently mutagenic, it is possible that methylation imprinting could alter the susceptibilities of human genes to point mutations.

Axonal branching of the olivocerebellar projection in the rat: a double-labeling study.

Collateralization of olivocerebellar (climbing) fibers was studied in the rat by means of the fluorochrome double-labeling technique. Most of the olivocerebellar projection is crossed except for a minimal ipsilateral component which arises from the most rostal part of the inferior olivary nucleus (ION). ION neurons in the caudolateral part of the medial accessory olive (MAO) and the dorsal accessory olive (DAO) give off axons that branch to supply both hindlimb areas of the contralateral cerebellar cortex, i.e., the rostral anterior lobe and the caudal paramedian lobule. In addition, neurons in the middle one-third of the contralateral MAO and DAO send axons that divide to terminate in both the caudal part of the anterior lobe and the rostral part of the paramedian lobule (forelimb receiving areas). Neurons within the caudal part of the MAO, the lateral part of the DAO, the ventral lamella of the principal olive (PO), and the dorsomedial cell column (DMCC) send axonal branches that terminate within at least two different areas of the same sagittal zones throughout the contralateral cerebellar cortex. Thus, the ION contains specialized cells that provide a divergence of integrated information from the ION to at least two cerebellar regions.
