Abstract
Titanium dioxide (TiO2) nanoparticles have gained significant attention due to their wide-ranging applications. This research explores an approach to functionalize Niobium Nitrogen Titanium Dioxide nanoparticles (Nb-N-TiO2 NPs) with Mentha arvensis ethanolic leaf extracts. This functionalization allows doped NPs to interact with the bioactive compounds in extracts, synergizing their antioxidant activity. While previous studies have investigated the antioxidant properties of TiO2 NPs synthesized using ethanolic extracts of Mentha arvensis, limited research has focused on evaluating the antioxidant potential of doped nanoparticles functionalized with plant extracts. The characterization analyses are employed by Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and Ultraviolet-visible (UV-Vis) spectroscopy to evaluate these functionalized doped nanoparticles thoroughly. Subsequently, the antioxidant capabilities through the 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric-reducing antioxidant power (FRAP) assays have been assessed. Within functionalized Nb-N-TiO2, the FTIR has a distinctive peak at 2350, 2010, 1312, 1212, and 1010 cm-1 with decreased transmittance associated with vibrations linked to the Nb-N bond. SEM revealed a triangular aggregation pattern, 500 nm to 2 µm of functionalized Nb-N-TiO2 NPs. Functionalized doped Nb-N-TiO2 NPs at 500 µg mL-1 exhibited particularly robust antioxidant activity, achieving an impressive 79% efficacy at DPPH assessment; meanwhile, ferric reduction efficiency of functionalized doped Nb-N-TiO2 showed maximum 72.16%. In conclusion, doped Nb-N-TiO2 NPs exhibit significantly enhanced antioxidant properties when functionalized with Mentha arvensis ethanolic extract compared to pure Nb-N-TiO2 manifested that doped Nb-N-TiO2 have broad promising endeavors for various biomedicine applications.

Abstract
Focused ultrasound (FUS) has emerged as a promising noninvasive therapeutic modality for treating atherosclerotic arterial disease. High-intensity focused ultrasound (HIFU), a noninvasive and precise modality that generates high temperatures at specific target sites within tissues, has shown promising results in reducing plaque burden and improving vascular function. While low-intensity focused ultrasound (LIFU) operates at lower energy levels, promoting mild hyperthermia and stimulating tissue repair processes. This review article provides an overview of the current state of HIFU and LIFU in treating atherosclerosis. It focuses primarily on the therapeutic potential of HIFU due to its higher penetration and ability to achieve atheroma disruption. The review summarizes findings from animal models and human trials, covering the effects of FUS on arterial plaque and arterial wall thrombolysis in carotid, coronary and peripheral arteries. This review also highlights the potential benefits of focused ultrasound, including its noninvasiveness, precise targeting, and real-time monitoring capabilities, making it an attractive approach for the treatment of atherosclerosis and emphasizes the need for further investigations to optimize FUS parameters and advance its clinical application in managing atherosclerotic arterial disease.

Abstract
Clostridium tetani produce tetanospasmin, a potent exotoxin; that causes tetanus or lockjaw disease. Scientists developed an anti-tetanus toxoid to protect the body from the spasm's neurotoxic effect. In Pakistan recently, 478 cases of neonatal tetanus were reported. The study was carried out at The National Control Laboratory for Biologicals Islamabad, aiming to decipher the effectiveness of the most frequently used tetanus toxoid vaccine adsorbed in Pakistan in comparison to standard reference vaccine having earlier known consistent values. The vaccines included domestic public sector, domestic private sector, imported private sector I, and imported private sector II. The triplicate experiments on purebred Swiss albino mice were performed by immunizing with Tetanus toxoid and then tested parallel with standard reference vaccine. Various analytical tests were performed on the test organism that included flocculation test/identity test, antibody quantification using enzyme-linked immunosorbent assay (ELISA), potency test, abnormal toxicity test, osmolality, pH test, liquid sub-visible particle test, and sterility test. Results of all the vaccines were compared in comparison with the standard reference vaccine. Absorbances of test vaccines were recorded at the lowest dilution by ELISA. The domestic private sector, imported private sector I, imported private sector II and standard reference vaccine were flocculated at mean dilution (Mean: 0.24, 95% CI: 0.1903–0.2897), and the domestic public sector was flocculated at mean dilution (Mean: 0.23, 95% CI: 0.2052–0.2548). All the products were found within the normal ranges where it was concluded that the maximum average titer of 2.81 was observed at dilution 10−1.6, indicating that these vaccines were adequate/suitable for the prevention of tetanus.

Abstract
Medicinal plants are known for their diverse use in the traditional medicine of the Himalayan region of Pakistan. The present study is designed to investigate the anticancer and antimicrobial activities of Prunus cornuta and Quercus semicarpifolia. The anticancer activity was performed using cancerous human cell lines (HepG2, Caco-2, A549, MDA-MB-231, and NCI-H1437 carcinoma cells), while the antimicrobial activity was conducted with the agar-well diffusion method. Furthermore, toxicity studies were performed on alveolar and renal primary epithelial cells. Initially, different extracts were prepared by maceration techniques using n-hexane, chloroform, ethyl acetate, butanol, and methanol. The preliminary phytochemical screening showed the presence of secondary metabolites such as alkaloids, tannins, saponins, flavonoids, glycosides, and quinones. The chloroform extract of P. cornuta (PCC) exhibited significant inhibitory activity against Acinetobacter baumannii (16 mm) and Salmonella enterica (14.5 mm). The A. baumannii and S. enterica strains appeared highly susceptible to n-hexane extract of P. cornuta (PCN) with an antibacterial effect of 15 mm and 15.5 mm, respectively. The results also showed that the methanolic extracts of Quercus semecarpifolia (QSM) exhibited considerable antibacterial inhibitory activity in A. baumannii (18 mm), Escherichia coli (15 mm). The QSN and QSE extracts also showed good inhibition in A. baumannii with a 16 mm zone of inhibition. The Rhizopus oryzae strain has shown remarkable mycelial inhibition by PCM and QSN with 16 mm and 21 mm inhibition, respectively. Furthermore, the extracts of P. cornuta and Q. semicarpifolia exhibited prominent growth inhibition of breast (MDA-MB-231) and lung (A549) carcinoma cells with 19-30% and 22-39% cell viabilities, respectively. The gut cell line survival was also significantly inhibited by Q. semicarpifolia (24-34%). The findings of this study provide valuable information for the future development of new antibacterial and anticancer medicinal agents from P. cornuta and Q. semicarpifolia extracts.

Abstract
OBJECTIVE To determine the outcome of patients undergoing extracorporeal shock wave lithotripsy (ESWL) for treatment of upper urinary tract calculi (renal and ureteric), and to note role of double-J (DJ) stents in these patients. DESIGN A cross-sectional analytical study. PLACE AND DURATION OF STUDY Department of Urology, Rawalpindi General Hospital, Rawalpindi, from February 1999 to July 2001. PATIENTS AND METHODS Record of patients who underwent ESWL for renal and ureteric stones was retrieved and analyzed using statistical program, SPSS version-10 and Epi-Info 2000. In some patients pre-ESWL DJ stents were placed because of various reasons like solitary kidney, large stone volume etc. Patients were divided in two groups, Group I, in whom DJ stents were not placed, and Group II, in whom DJ stents were placed. ESWL was performed in each subject in standard way employing piezoelectric lithotripter E.D.A.P. LT 02X. Patients were evaluated for stone clearance fortnightly with X-ray or ultrasound. RESULTS Four hundred and thirty-two patients, 68.8% male and 31.2% female, underwent ESWL. Mean age of patients was 37.7 +/- 13.1 years. Majority of patients (78.47%, n = 339) had renal, while rest had ureteric stones. Group I and II included 408 (94.4%) and 24 (5.6%) patients respectively. Renal stones were present in 78% (n=318) of Group I and 87.5% [n = 21] of Group II patients. Mean size of stones in Group I and II patients was 10.91 +/- 4.6, and 10.4 +/- 4.7mm. Stone clearance was 96.3% and 100% in Group I and Group II patients respectively. Significantly more ESWL sessions were required for stone clearance in Group II (p-value 0.03); in addition Group II patients had significantly more complications (p-value 0.01). CONCLUSION ESWL is an effective procedure. Pre-ESWL stenting is associated with increased numbers of ESWL sessions and more complications.
