Background: Benign prostatic hyperplasia (BPH) is the proliferation of the stromal and epithelial cells of the prostate gland, resulting in an increase in its size. This may result in obstruction of the lower urinary tract causing storage and voiding symptoms. Methods: This was a prospective cross-sectional study from August 2020 to July 2021, to evaluate the characteristic of patients presenting to the Tamale Teaching Hospital with lower urinary tract symptoms secondary to BPH. Results: The median age at presentation with lUTS secondary to BPH is 68.88 ± 11.10 years with an average prostate volume of 70 g. The average time of presentation to the hospital is 5 months, mostly with moderate to severe symptoms. correlation between Prostate volume (PV) and age yielded a positive relationship;however, this was not statistically significant, (r = 0.028, p-value = 0.747). There was a significant positive relationship between PV and the IPSS score, (r = 0.334, p-value conclusion: Our patients with symptomatic BPH present at age 60 years and above, with nearly all of them presenting with moderate to severe lUTS.

lithium/fluorinated-carbon（li/cFx） primary batteries are widely used in defense and military fields due to their stable discharge plateau, low self-discharge rate, and adaptability across a wide temperature range. However, enhancing their overall energy density and discharge capacity at low temperatures remains a critical challenge. Herein, we report a strategically designed liBF4-based sulfite/carboxylate electrolyte, where the anion-involved solvation structure significantly enhances electrochemical kinetics by reducing the desolvation barrier. Simultaneously, it introduces a radical reaction mechanism that contributes to additional capacity. As a result, the li/cFxprimary batteries with this formulated electrolyte deliver a specific capacity of 2,257.15 mAh g-1at 25 °c. More importantly, when operating at -40 °c, the batteries exhibit an exceptionally high discharge capacity of 1,549.4 m Ah g-1and an energy density of 2,868.6 wh kg-1. Even at -60 °c, the li/cFxcells achieve a specific capacity of 444.3 mAh g-1and an energy density of 821.8 wh kg-1at 0.1 c, significantly outperforming previously reported organic-based liquid electrolytes. This work offers a viable strategy for enhancing the specific capacity and energy density of primary batteries in extreme environments, providing valuable insights for future developments.

Inflammation and angiogenesis, the major pathological changes of osteoarthritis (OA), are closely associated with joint pain; however, pertinent signalling interactions within subchondral bone of osteoarthritic joints and potential contribution to the peripheral origin of OA pain remain to be elucidated. Herein we developed a unilateral anterior crossbite mouse model with osteoarthritic changes in the temporomandibular joint. Microarray-based transcriptome analysis, besides quantitative real-time polymerase chain reaction, was performed to identify differentially expressed genes (DEGs). Overall, 182 DEGs (fold change ≥ 2, P were identified between the control and unilateral anterior crossbite groups: 168 were upregulated and 14 were downregulated. On subjecting significant DEGs to enrichment analyses, inflammation and angiogenesis were identified as the most affected. Inflammation-related DEGs were mainly enriched in T cell activation and differentiation and in the mammalian target of rapamycin/nuclear factor-κB/tumour necrosis factor signalling. Furthermore, angiogenesis-related DEGs were mainly enriched in the Gene Ontology terms angiogenesis regulation and vasculature development and in the KEGG pathways of phosphoinositide 3-kinase-protein kinase B/vascular endothelial growth factor/hypoxia-inducible factor 1 signalling. Protein– protein interaction analysis revealed a close interaction between inflammation-and angiogenesis-related DEGs, suggesting that phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit delta (Pi3kcd), cathelicidin antimicrobial peptide (camp), c-X-c motif chemokine receptor 4 (cxcr4), and MYB proto-oncogene transcription factor (Myb) play a central role in their interaction. To summarize, our findings reveal that in subchondral bone of osteoarthritic joints, signal interaction is interrelated between inflammation and angiogenesis and associated with the peripheral origin of OA pain; moreover, our data highlight potential t
