Despite extensive research efforts, there is currently no cure for ALS and existing treatments only address its symptoms. To address this unmet medical need, genome editing technologies, such as CRISPR-Cas9, have emerged as a promising solution for the development of new treatments for ALS. Studies have shown that CRISPR-Cas9-guided RNAs have the potential to provide accurate and effective silencing in the genetic disease of ALS. Results have demonstrated a 67% on-target score and a 98% off-target score with GC content within the range of 40-60%. This is further validated by the correlation between the gRNA's structural accuracy and the minimum free energy. The use of CRISPR-Cas9 provides a unique opportunity to target this disease at the molecular level, offering hope for the development of a more effective treatment. In silico and computational therapeutic approaches for ALS suggest that the CRISPR-Cas9 protein holds promise as a future treatment candidate. The CRISPR mechanism and the specificity of gRNA provide a novel therapeutic approach for this genetic disease, offering new hope to those affected by ALS.

Certain NAT2 SNPs were associated with BC and/or modified the association of BC with smoking. However, limited evidence is available among BC patients or smokers from Jordan. This study aimed to discover novel SNPs in NAT2 and to assess the association with BC. This was a case-control study among 120 BC patients and 120 controls. Amplification of a 446 bp fragment of NAT2 encoding the N-catalytic domain was conducted using a polymerase chain reaction. Gene sequencing was done using Sanger-based technology. A total of 40 SNPs were detected. Two variants were significantly associated with BC (p<0.05); namely a novel c.87G>A and the reported c.341T>C. Regarding c.87G>A, genotype distribution was significantly associated with BC and subgroup analysis confirmed that this was significant in both smokers (p=0.007) and non-smokers (p=0.001). Regression subgroup analysis suggested GA as a risk factor among smokers (AOR= 2.356). The frequencies of TC and CC genotypes of c.341T>C were significantly higher in BC (p<0.05).

Quercetin 3-O-glucoside (QUE-G) was isolated and characterized by modern spectroscopic techniques. RBFCE was orally administered at 250 mg/kg, 500 mg/kg, and 750 mg/kg doses for ten days.

Gastric juice volume, pH, acidity, mucus content, and protein content were evaluated to understand the mechanism underlying its gastroprotective effect. Omeprazole (OMP) was used as the positive control. RBFCE at a dose of 750 mg/kg significantly (p<0.01) reduced the UI (3.54) and increased the protection rate (67.63%) compared to the negative (ulcer) control group. Treatment with RBFCE in a dose-dependent manner increased the gastric pH, mucus content, and total protein while decreasing gastric juice volume and total acidity. Histopathological studies showed severe gastric mucosal injury and edema in ulcer control animals compared to extract-treated groups.

Numerous ever-evolving antigens are produced as a result of HIV-1's genetic variability. Developing an effective vaccination is challenging because of the structural properties of the viral envelope glycoprotein that obscure conserved receptor-binding sites and the presence of carbohydrate moieties that prevent antibodies from reaching potential epitopes. To work on an HIV-specific vaccine, this study identified 5 HIV-surface proteins, from the literature, to screen potential epitopes and construct an mRNA vaccine. A wide range of immunological-informatics techniques were utilized to develop a construct that efficiently stimulated cellular and humoral immune responses. The vaccine was produced with 31 epitopes, a TLR4 agonist termed RpfE that acts as an adjuvant, secretion boosters, subcellular trafficking structures, and linkers. It was determined that this suggested vaccine would cover 98.9 percent of the population, making it widely available. We, furthermore, carried out an immunological simulation of the vaccine illustrating the active and stable responses from innate and adaptive immune cells, the memory cells remained active for up to 350 days after vaccine injection, whereas the antigen was excreted from the body within 24 hours.
