Triflusal is a prodrug used as a platelet antiaggregant agent (a platelet aggregation inhibitor). It has efficacy similar to that of aspirin specially in patients with cerebral and myocardial infraction. Chemically, triflusal is nothing except a derivative of acetylsalicylic acid (2-acetyl-3-trifluoromethylsalicylic acid). It is bio-transformed under the effect of a deacetylation process into the active metabolite (known as HTB) which is 2-hydroxyl-3-trifluoromethylbenzoic acid. During the triflusal uses the cutaneous phototoxic/photoallergic side effect is noted including rash, itching or allergic reactions. In order to study this side effect, we use a very excellent tool to study such reactions which is DFT and TD-DFT. The active metabolite of triflusal HTB molecular orbitals and UV-VIS spectroscopic features have been investigated herein. The obtained results show that there is a difference in the molecular orbitals (MOs) pattern between the two forms of HTB (protonated and deprotonated) especially the HOMOs of the deprotonated species..

Abstract: In this study, we introduce a novel approach to the solution of a nonlinear Volterra -Fredholm integral equations by applying the Adomian decomposition method under the effect of the Abaoub- Shkheam transform. We demonstrate the existence and uniqueness of the solution in Banach space and illustrate this idea with an example.

Seven sedimentary rocks and seven crude oils undertook a geochemical analysis to describe their organic matter type and

then tag the Paleoenvironments based on the organic matter. The samples were collected from B1-NC151, A1-NC58, P1-

NC1, E1-NC174, D1-NC151, H29-NC115, and D1-NC174 boreholes, located in Murzuq Basin. The study was established to

understand life forms in the ecosystem based on biomarkers that biochemical techniques recognized. Microscopy was used

for kerogen typing and Spore Color Index reference. Organic matter (EOM) was extracted from cutting samples. Furthermore,

hydrocarbons were saturated and aromatic fractionated from the samples to investigate using Gas chromatograph system.

Spore color index (SCI), range between 1.5-3.5, Amorphous organic matter (AOM) from 42 to 95 percentage, Phytoclasts %

were 4-15.5, and Palynomorphs % range 0.5 to 7.5. The percentage of Carbon 85.66-86.29, Hydrogen 13.16-13.73, Nitrogen

0.06 -0.27, and Sulfur 0.31-0.70, besides wax were measured, ranging among 1.3 to 6.0 %. Pristine/n-C17, Phytane/n-C18,

Pristine/Phytane, carbon preference index measurements (CPI) and DBT/P as saturated hydrocarbon ratios from whole oil

chromatographs were established. Tricyclic terpanes, hopanes and n-alkanes were distinguishing as the most important oil

biomarkers that reserved the characteristics in the Paleoenvironments. 

Introduction: Diabetes is a common condition among pregnant women, and a high glycated haemoglobin (HbA1c) level can indicate poor outcomes for both the mother and the fetus. This report presents a case of an unknown diabetic primigravida with a significantly elevated HbA1c level, which resulted in severe complications during pregnancy and adverse fetal outcomes. Case Study: A 37-year-old primigravida was referred to the emergency obstetrics and gynaecology clinic, where she reported a notable decrease in fetal movements and feelings of lethargy. Laboratory tests revealed a significantly elevated blood sugar level. After assessing fetal well-being, the decision was made to terminate the pregnancy at 33 weeks and 2 days due to severe fetal distress. Immediate treatment was initiated to control the high blood sugar levels. The outcome was the delivery of a preterm boy who presented with multiple biochemical imbalances and required admission to the neonatal intensive care unit (NICU). Conclusion: Improving hyperglycemia and glycated haemoglobin levels to lower than the upper normal limits during both the preconception and post-conception phases can significantly reduce morbidity and mortality for mothers and their fetuses.

Eighty-five rock samples corresponding to the Palaeozoic formations were taken from two wells in

the NC 200 Block of the Murzuq Basin. The study aimed to find out geochemical characteristics of

parameters and specific Gas Chromatography-Mass Spectrometry (GC-MS) biomarkers were 

applied to determine the potential hydrocarbon generation. Per se, Rocks are good sources and 

hold fair content of organic matter, crossing in the range of good accumulation, in which the very 

good source rocks have an organic carbon richness (TOC) reached of 3.7 wt%. The studied rocks 

are ranged from immature to late mature organic matter (OM) with total organic carbon richness 

(TOC) range between 0.4 – 3.7 wt%. Rock-Eval parameters S1, S2, S3, Tmax, S2/S3, OI, PI and HI 

of the source rock samples have values ranged from 0.02 – 0.3, 0.22 – 6, 0.36 – 4, 423 – 443, 24= 

350, 0 – 0.27 and 42 – 384 respectively. The range of hydrogen index (HI) related to oxygen index 

(OI) displays that all kerogen types from Type II to Type III are exist and increase with depth. The 

Tmax parameter is wide-ranging among studied formations, indicating different levels of organic 

matter maturity, from immature oil window and to late mature for the Devonian-Carboniferous and 

Silurian source rocks, associated with more depth. Molecular composition analysis of n-alkanes and 

other biomarkers supported the findings of Rock-Eval pyrolysis data, revealing varied hydrocarbon 

signatures across the formations. The Carbon isotope analysis (δ13C) suggested multiple sources 

contributing to the generated oil, including Type I to Type III kerogens. Silurian Bir Tlacsin/Tanezzuft Formations, the Devonian Awaynat Wanin/BDS II Formations, and

Large outbreaks of skin lesions in cattle have been observed recently throughout the governorate. The LSDV was

shown to be the causative factor. The local strain of LSDV was sequenced and deposited into GenBank, where it

was assigned the accession number MK552139 and designated as LSDV/Egy-BSU/2018. The discovered strain

resources were connected and to other LSDVs, however the phylogenetic tree clustered viruses of sheep pox, goat

pox, and LSD viruses independently.

ABSTRACT: Study area situated in the center of the Hameimat trough which is located in the southeast of the Sirte basin. The Hameimat trough contains two of the largest oil fields in Libya, Gialo and Abu-Attifel fields. The Upper Cretaceous Rachmat, Tagrifet, and Sirte Formations are considered as the main source rock in Sirte Basin.Organic geochemical study of the Upper Cretaceous Rachmat, Tagrifet and Sirte Formations show these Formations have total organic carbon content values of 0.53% to 3.35% fair to excellent as source rock. The Kerogen types are type II and III mixed continental and marine organic matter. The thermal maturity of these formations indicates a mature stage in oil window.Oil saturation index (OSI: S1*100/TOC) shows that Sirte and Rachamt formations have low oil saturation, while the Tagrifet formation has good potential, where OSI exceeds 140 mg HC/g TOC in the most samples of the formation. The Tagrifet formation considers a good unconventional reservoir for shale oil, where the Sirte and Rachmat formations consider possible for shale oil with high risk.

Abstract: New footprints of theropod dinosaurs were discovered near Sebha city, southwestern Libya. It is the only known dinosaur record from the Jurassic to Lower Cretaceous period within the Messak Formation. The dinosaur footprints have been examined, counted, measured, photographed, and described to deduce the type of dinosaur, its size, shape, walking style, potential diet, and, if possible, its social interactions with other individuals. A total of 183 clear dinosaur footprints were found and documented, and at least two main sizes of footprints have been defined, characterized, and categorized into two groups: large footprints and small ones. The examined footprints made by an upright dinosaur stood and walked on its two hind feet on a humid layer composed of clay, silt, and fine sand. These footprints suggest they may belong to the theropod group of dinosaurs. The size of these footprints ranges from 20 to 60 cm, and the most common type is characterized by an angle of 50 to 70 degrees between the outermost digits. The foot size suggests that the trace makers' height at the pelvis ranged from 0.8 to 2.4 m, while the overall length of the creature reached 9 m from head to tail. A close examination of the footprints reveals almost equal distances between each footprint, indicating that the animals were moving with coordinated, normal steps and walking in their typical gait. Consequently, they were not in a state of chase or escape from any potential dangers. Based on the current state of knowledge, we believe there are two possible interpretations regarding the preservation of these footprints. Physical and chemical processes, such as consolidation, cementation, and the formation of a crust of iron oxides, played a crucial role in preserving the dinosaur footprints within fragile sediments primarily composed of silt and mudstone beds, which are covered by thin layers of sandstone.
