Benign prostatic hyperplasia (BPH) is a chronic disorder that inflicts severe symptoms on middle-aged men. The current study compared the effects of tadalafil and tamsulosin on urological parameters after 3 and 6 months of therapy. A retrospective case–control study was conducted, in which 100 patients with moderately severe BPH were divided into two groups based on their treatment: 50 patients were given tamsulosin 0.4 mg/day and group 50 patients were administered tadalafil 5 mg daily. All patients continued therapy for approximately 6 months, and their urological parameters were assessed at baseline and after 3 and 6 months. There was no significant difference in the overall effect on the International Prostate Symptom Score at the end of the study using two-way ANOVA analysis (P = 0.448). The intercourse number was significantly improved by tadalafil compared to tamsulosin (P < 0.001). The prostatic-specific antigen, postvoiding residual, and prostatic volumes were not significantly different between tadalafil and tamsulosin (P = 0.198, 0.163, and 0.183, respectively). In conclusion, tadalafil, 5 mg once daily, appears to have similar efficacy to tamsulosin, with significant improvement in the patient’s erectile function. Tadalafil can be used for 6 months for moderate-to-severe lower urinary tract symptoms.

Hydrogels have gained much focus as a gastro-retentive technology for drug delivery. The current study aimed to design an oral mucoadhesive sustained-release dosage form to lower peptic ulcer complications (PUC). Using the Box-Behnken statistical design, the preparation method was developed by incorporating pantoprazole sodium (PZS) into hydrogel microcapsules (HGMC). The PZS was incorporated into the HGMC via an ion gelation technique, with sodium alginate as the gelling agent, calcium chloride as the crosslinking agent, and chitosan as the agent for sustained release. The optimized formulation of PZS-HGMC showed a diameter of 2.506 mm, a swelling rate of 838.2%, and an encapsulation efficiency of 93.8%. Scanning electron microscopy images revealed the microcapsules’ spherical shape. The in vitro release of the PZS from the HGMC after two hours in a simulated gastric fluid was 13.2%1±0.08%, compared with the apparent solubility of the pure PZS under the same conditions (95.24%±3.2%). After 24 hours, the percent of PZS released from the optimized formula was 69.84±2.4%, which indicates a sustained release pattern. The results from the in vivo study demonstrated improved healing of the induced ulcers in rats when treated with the PZS-HGMC formulation as compared to the standard PZS therapy; therefore, the obtained mucoadhesive HGMC was considered a potential drug delivery strategy for PUC therapy.

Off-grid and grid-connected photovoltaic (PV) systems with battery storage rely heavily on efficient energy transfer to maximize PV power utilization and battery lifespan. However, existing literature often overlooks the crucial role of energy transfer efficiency in these systems. This paper proposes a novel, fundamental-based PV power flow strategy that addresses this gap by employing a concept of source-load voltage matching. The proposed strategy ensures optimal voltage matching between the PV array and the battery bank. This is achieved by configuring the battery bank voltage range (between nominal and fully charged states) to closely align with the variation in PV voltage at its Maximum Power Point (MPP) across different operating temperatures. This systematic approach requires specifying the DC load voltage, configuring the battery bank, and selecting PV modules with compatible Vmp (voltage at maximum power) parameters. The system utilizes a high-current blocking diode and current limiter for safe connection between the PV array and battery bank. Additionally, the strategy protects against battery overcharge by controlling parallel fans used for PV panel cooling. Experimental results with a 1.62 kW PV system employing lead-acid batteries demonstrate improved efficiency compared to traditional methods. This innovative approach has the potential to significantly enhance energy transfer efficiency, contributing to improved energy sustainability in PV systems.

BackgroundDiabetes mellitus (DM) is well known for related micro and macrovascular complications. Uncontrolled hyperglycemia in diabetes mellitus leads to endothelial dysfunction, inflammation, microvascular impairment, myocardial dysfunction, and skeletal muscle changes which affect multiple organ systems. This study was designed to take an extensive view of cardiorespiratory dynamics in patients with type 2 DM.MethodsOne hundred healthy controls (HC) and 100 DM patients were enrolled. We measured and compared the breathing patterns (spirometry), VO2 max levels (heart rate ratio method) and self-reported fitness level (international fitness scale) of individuals with and without diabetes. Data was analyzed in SPSS v.22 and GraphPad Prism v8.0.ResultsWe observed restrictive spirometry patterns (FVC ConclusionThis study shows decreased pulmonary functions, decreased cardiorespiratory fitness (VO2 max) and IFiS scale variables in diabetic population as compared to healthy controls which are also associated with glycemic levels and long-standing DM. Screening for pulmonary functions can aid optimum management in this population.

Traumatic brain injury (TBI) leads to brain damage, comprising both immediate primary damage and a subsequent cascade of secondary injury mechanisms. The primary injury results in localized brain damage, while the secondary damage initiates inflammatory responses, followed by the disruption of the blood-brain barrier, infiltration of peripheral blood cells, brain edema, and the release of various immune mediators, including chemotactic factors and interleukins. TBI disrupts molecular signaling, cell structures, and functions. In addition to physical tissue damage, such as axonal injuries, contusions, and haemorrhages, TBI interferes with brain functioning, impacting cognition, decision-making, memory, attention, and speech capabilities. Despite a deep understanding of the pathophysiology of TBI, an intensive effort to evaluate the underlying mechanisms with effective therapeutic interventions is imperative to manage the repercussions of TBI. Studies have commenced to explore the potential of employing natural compounds as therapeutic interventions for TBI. These compounds are characterized by their low toxicity and limited interactions with conventional drugs. Moreover, many natural compounds demonstrate the capacity to target various aspects of the secondary injury process. While our understanding of the pathophysiology of TBI, there is an urgent need for effective therapeutic interventions to mitigate its consequences. Here, we aimed to summarize the mechanism of action and the role of phytochemicals against TBI progression. This review discusses the therapeutic implications of various phytonutrients and addresses primary and secondary consequences of TBI. In addition, we highlighted the roles of emerging phytochemicals as promising candidates for therapeutic intervention of TBI. The review highlights the neuroprotective roles of phytochemicals against TBI and the mechanistic approach. Furthermore, our efforts focused on the underlying mechanisms, providing a better understanding of the therapeutic potential of phytochemicals in TBI therapeutics.
