Abstract
Soft corals, particularly Sarcophyton sp. are rich in metabolites with variety of biological activities. In this study, a pyran-based 9-exo-methylene-10-hydroxy-sarcotrocheliol (1) and 2-dehydro-4-peroxy-sarcophine (2), two new cembranoide diterpenes, were isolated together with 9-hydroxy-10,11-dehydro-sarcotrocheliol, sarcotrocheliol, sarcotrocheliol acetate, sarcophine, (+)-7α,8β-dihydroxydeepoxysarcophine, (±)-sarcophytonine B, and peridinin from the organic extract of Sarcophyton glaucum collected at the coasts of Hurghada, Egypt. The structures of the new diterpenes 1-2 were identified based on cumulative analyses of HRESIMS and NMR (1D/2D NMR) spectra. The relative configurations of both compounds were verified by NOESY spectra and comparison with our recently reported analogues. The compounds showed no antimicrobial activity against a set of diverse tested microorganisms.

Abstract
The experiment was carried out on mango cv. Dusehri to investigate the effect of N, P and K fertilizers on vegetative, reproductive growth, yield and fruit quality. Eight different fertilizer combinations such as T1 (control), T2 (N), T3 (P), T4 (K), T5 (NP), T6 (NK), T7 (PK) and T8 (NPK) were used. Individual or combine fertilizer application of N (1000 g), P (750 g) and K (750 g) were applied during growing season in February and August. All the treatments significantly influenced on vegetative growth, flowering, fruiting, yield and other physiochemical attributes of mango as compared to control. Least effect was observed with individual fertilizer application while combine fertilizer treatments enhanced most of the investigated parameters. Especially, qualitative traits showed non-significant differences between treated and untreated mango trees. However, among the different treatments T8 (NPK) showed significance for fruiting aspects such as maximum size of growth flushes (177.51 mm), total number of panicles/tree (845), total number of flowers/panicle (974), sex ratio (69.18%), fruit retention (13.85%), total number of fruits/tree (379), yield (82 kg/tree), fruit weight (197.5 g), pulp weight (135.5 g) and physiochemical parameters namely TSS (24.53), Vit. C (57.63 mg/100 mL) and total sugar (20.84%). In general, combine application of NPK (T8) were the most effective in enhancing fruiting aspects, yield, physiochemical characteristics as well as improved fruit quality of mango trees.

Abstract
The COVID-19 pandemic had significant impact on health care worldwide which has led to a reduction in all elective admissions and management of patients through virtual care. The purpose of this study is to assess changes in STEMI volumes, door to reperfusion, and the time from the onset of symptoms until reperfusion therapy, and in-hospital events between the pre-COVID-19 (PC) and after COVID-19 (AC) period. All acute ST-segment elevation myocardial infarction (STEMI) cases were retrospectively identified from 16 centers in the Kingdom of Saudi Arabia during the COVID-19 period from January 01 to April 30, 2020. These cases were compared to a pre-COVID period from January 01 to April 30, 2018 and 2019. One thousand seven hundred and eighty-five patients with a mean age 56.3 (SD ± 12.4) years, 88.3% were male. During COVID-19 Pandemic the total STEMI volumes was reduced (28%, n = 500), STEMI volumes for those treated with reperfusion therapy was reduced too (27.6%, n= 450). Door to balloon time < 90 minutes was achieved in (73.1%, no = 307) during 2020. Timing from the onset of symptoms to the balloon of more than 12 hours was higher during 2020 comparing to pre-COVID 19 years (17.2% vs <3%, respectively). There were no differences between the AC and PC period with respect to in-hospital events and the length of hospital stay. There was a reduction in the STEMI volumes during 2020. Our data reflected the standard of care for STEMI patients continued during the COVID-19 pandemic while demonstrating patients delayed presenting to the hospital.

Abstract
Spontaneous coronary artery dissection (SCAD) has emerged as an important cause of acute coronary syndrome and sudden cardiac death. The triggers for SCAD often do not include traditional atherosclerotic risk factors. The most commonly reported triggers are extreme physical or emotional stress. The current study compared in-hospital and follow-up events in patients with SCAD with and without reported stress. Data from 83 patients with a confirmed diagnosis of SCAD were collected retrospectively from 30 centers in 4 Arab Gulf countries (KSA, UAE, Kuwait, and Bahrain) from January 2011 to December 2017. In-hospital myocardial infarction (MI), percutaneous coronary intervention (PCI), ventricular tachycardia/ventricular fibrillation, cardiogenic shock, death, ICD placement, dissection extension) and follow-up (MI, de novo SCAD, death, spontaneous superior mesenteric artery dissection) events were compared between those with and without reported stress. Emotional and physical stress was defined as new or unusually intense stress, within 1 week of their initial hospitalization. The median age of patients in the study was 44 (37-55) years. Foty-two (51%) were women. Stress (emotional, physical, and combined) was reported in 49 (59%) of all patients. Sixty-two percent of women with SCAD reported stress, and 51 % of men with SCAD reported stress. Men more commonly reported physical and combined stress. Women more commonly reported emotional stress (P < 0.001). The presence or absence of reported stress did not impact on overall adverse cardiovascular events (P = 0.8). In-hospital and follow-up events were comparable in patients with SCAD in the presence or absence of reported stress as a trigger.

Abstract
Abstract
9-Hydroxy-10,11-dehydro-sarcotrocheliol (1), a new pyrane-based cembranoid diterpene, has been isolated along with three other known compounds, namely, sarcotrocheliol acetate (2), (+)-sarcophytol A (3), and (−)-sarcophytonin A (4), from the organic extract of the soft coral Sarcophyton trocheliophorum. The chemical structures of compounds 1–4 were determined on the basis of their 1D and 2D NMR [1H, 13C, 1H–1H correlation spectroscopy, heteronuclear multiple-quantum coherence, heteronuclear multiple-bond correlation, and nuclear Overhauser effect (NOE)] and mass spectra [electron ionization (EI), electrospray ionization, and high resolution mass spectrometry (HRMS)], and by comparison with related structures. The compounds 1–4 showed neither antimicrobial activity against 11 diverse tested microorganisms, nor cytotoxicity against brine shrimp, whereas the soft coral extract showed low cytotoxicity with a mortality rate of 1.7%.

Abstract
Two new poly-hydroxy steroids, zahramycins A (1) and B (2), have been isolated from the polar fraction of the extract of the coral Sarcophyton trocheliophorum. Compound 1 was confirmed to bear an oxirane ring at C-5 and C-6, while 2 has a keto-hydroxy sterol structure. The known DNA primary metabolites uracil, thymine, adenine, uridine, 2´-deoxyuridine, and thymidine were also isolated and identified. Structures of the new sterols 1 and 2 were confirmed by NMR ( 1H, 13C, 1H-1H COSY, HMQC, HMBC, and NOESY) spectroscopy, mass spectrometry (EI, ESI, and HRMS), and by comparison with related structures. The antimicrobial and cytotoxic activities of compounds 1 and 2 along with that of the coral extract were also determined. Zahramycin B (2) showed high (15 mm) and moderate (12 mm) antibacterial activity against Staphylococcus aureus and Bacillus subtilis, and fungus Pythium ultimum (12 mm), while zahramycin A (1) and the crude extract of Sarcophyton trocheliophorum were inactive. Both steroids and the crude extract of Sarcophyton trocheliophorum showed no cytotoxicity.

Abstract
UNLABELLED BACKGROUND More than 15,000 marine products have been described up to now; Sponges are champion producers, concerning the diversity of products that have been found. Most bioactive compounds from sponges were classified into anti-inflammatory, antitumor, immuno- or neurosurpressive, antiviral, antimalarial, antibiotic, or antifouling. Evaluation of in vitro inhibitory effects of different extracts from four marine sponges versus some antioxidants indices and carbohydrate hydrolyzing enzymes concerned with diabetes mellitus was studied. The chemical characterizations for the extracts of the predominating sponges; SP1 and SP3 were discussed. METHODS All chemicals served in the biological study were of analytical grade and purchased from Sigma, Merck and Aldrich. All kits were the products of Biosystems (Spain), Sigma Chemical Company (USA), Biodiagnostic (Egypt). Carbohydrate metabolizing enzymes; α-amylase, α-glucosidase, and β-galactosidase (EC3.2.1.1, EC3.2.1.20, and EC3.2.1.23, respectively) were obtained from Sigma Chemical Company (USA). RESULTS Four marine sponges; Smenospongia (SP1), Callyspongia (SP2), Niphates (SP3), and Stylissa (SP4), were collected from the Red Sea at Egyptian coasts, and taxonomically characterized. The sponges' extracts exhibited diverse inhibitory effects on oxidative stress indices and carbohydrate hydrolyzing enzymes in linear relationships to some extent with concentration of inhibitors (dose dependant). The extracts of sponges (3, 1, and 2) showed, respectively, potent-reducing power. Purification and Chemical characterization of sponge 1 using NMR and mass spectroscopy, recognized the existence of di-isobutyl phthalate (1), di-n-butyl phthalate (2), linoleic acid (3), β-sitosterol (4), and cholesterol (5). Sponge 3 produced bis-[2-ethyl]-hexyl-phthylester (6) and triglyceride fatty acid ester (7). CONCLUSION Marine sponges are promising sources for delivering of bioactive compounds. Four marine sponges, collected from Red Sea at Egyptian coasts, were identified as Smenospongia (SP1), Callyspongia (SP2), Niphates (SP3), and Stylissa (SP4). The results demonstrated that different sponges extracts exhibited inhibitory effects on oxidative stress indices and carbohydrate hydrolyzing enzymes in linear relationships to some extent with concentration of inhibitors (dose dependant). The extracts of sponges (3, 1, and 2) showed, respectively, potent-reducing power. Chemical characterizations of sponges SP1 and SP3 were discussed. Based on this study, marine sponges are considered as talented sources for production of diverse and multiple biologically active compounds.

Abstract
OBJECTIVE To define the sociodemographic and clinical aspects of organic phosphate and carbamate poisoning. DESIGN The records of 70 adults (33 males and 37 females) with carbamate or organophosphate intoxication admitted to a North Jordan Teaching Hospital over a five-year period were reviewed retrospectively. These patients represented 10% of all drug overdoses admitted over the same period. RESULTS The most cases occurred in the 15-19 year-old age group and the female to male ratio was 1.1:1. Carbamate intoxication was more than twice as common as organophosphate intoxication. Two thirds (64%) of the patients intended to commit suicide, 26% were due to accidental ingestion and the remaining 10% were from occupational exposure. Muscarinic manifestations were the predominant clinical feature followed by central nervous system and then nicotinic manifestations. Low grade fever, not related to infection, was observed in 49% of the patients and respiratory difficulty in 47%, of which 11% required assisted ventilation. Twenty-nine percent of the patients presented with coma. Three patients died for a hospital mortality of 4%. CONCLUSIONS The widespread use of carbamates and organophosphates as household pesticides and the lack of adequate regulations controlling their sale and application has encouraged teenagers to prefer them as a modality of attempted suicide. This source of poisoning has become a major health problem in some developing countries.

Abstract
Ten patients with complex non-union of the tibia were treated by locked intramedullary nailing. These patients had scarred skin as a result of initial severe open fractures, multiple debridement or fasciotomies with external fixators and skin grafts applied. Seven of the patients also had previous osteomyelitis or pin track infections. Fully pain-free walking was achieved in all patients and radiological union in nine patients without the need for a bone graft. Four patients developed infection after nailing, of which three resolved with treatment.

Abstract
Ketamine, most often used as an anaesthetic agent can provide adequate post operative analgesia when delivered in the form of infusion, replacing narcotics, which can cause bronchospasm in susceptible individuals. This cohort study was undertaken to assess the feasibility of providing complete post operative analgesia in asthmatics with ketamine delivered in sub-anaesthetic doses (6.10-6.41 ugm./kg.-1/min-1). Diazepam (0.97-1.02 ugm./kg.-1/min-1) was delivered from the same infusion to eliminate the unwanted effects of ketamine. Ketamine induced little alteration in blood pressure while tachycardia was significant (P < 0.05). Respiratory functions observed, were favourable for asthmatics. Diazepam helped in reducing ketamine induced side effects, but after infusion over long periods tendency of cumulation was observed. Complications encountered were minimum with more than 93% patient acceptability for this method of analgesia.
